Why do you need to use wood grain paint with steel structure

               With the rapid development of the mineral industry, the previously precious metals, such as steel and iron, are currently very favorable. Therefore, many buildings are now used in metals such as steel structures, iron pipes, such as steel structure guardrails, iron pipe guardrails, steel structure gazebo, steel structure flower stand, metal corridor and other metal structures:

Due to the characteristics of steel structures, because of its own characteristics, it is easy to be affected by the water in the air or the rain, snow and frost in the natural world, and high and low temperature, and produces rust stains. It not only affects the perception, but also affects the service life of these buildings. However, after the decoration of wood grain paint, the surface of these metals will form a protective film, which effectively isolates the water in the air and the impact of wind and frost in nature on metal.

Secondly, I have to talk about the feel of the steel structure, iron pipe and other materials. The feel of these metal itself has a little rustic feeling, and the hand feels smooth and moisturized after the wood grain paint becomes the film, and the feel is very good. If you are not making wood paint on the metal surface, it is easy to score your hands or other parts when the temperature is too high. After making wood grain paint, not only the heating of the metal, but also the metal feel.

Finally, let's talk about the appearance of the metal. The appearance of the metal, whether it is steel structure or iron pipe and other metals, the surface of the building is monochrome. In addition to inconsistency with the surrounding environment, it also does not seem to have a little natural beauty, and the overall looks full of sharp feelings. However, if the wood grain paint is made, the wood grain paint gives a more gentle and stable feeling of metal building.

Installation standards for steel structure engineering

Steel structures are widely used in the construction industry. Steel structure workshops are the first choice of many entrepreneurs because they can store a large number of products. The SAFS steel structure manufacturer will take you to understand what the engineering installation standards are.

 

1. Marks should be set at the end of the steel to indicate the specification, grade, quantity and material acceptance certificate number of the steel;

 

2. When stacking in the open air, the site should be flat, higher than the surrounding ground, and drainage ditches should be set around;

 

3. When stacking, try to make the back of the section steel face upward or outward to avoid snow and water accumulation. There should be a height difference at both ends to facilitate drainage;

 

4. Before installation, the construction unit should conduct special inspections on the product qualification certificates, design documents and pre-assembly records of the components, and review and record the dimensions of the components;

 

5. Appropriate connection methods should be adopted to make the joint design consistent with the simplified structural calculation model;

 

6. When hoisting the steel structure, appropriate measures should be taken to prevent excessive bending and torsional deformation, and heat blocks should be placed at the contact between the rope buckle and the component to prevent damage to the component;

 

7. After the steel structure is hoisted in place, the brackets and other connecting parts should be fastened in time to ensure the stability of the structure;

 

8. When using tools at high places, spare parts should be put into the tool bag, and they should not be thrown up and down;

 

9. When working in rainy days, reliable anti-skid measures should be taken, and lightning protection should be paid attention to during thunderstorm seasons;

 

10. Before construction, the weather conditions are good, and no work is allowed if the wind is above level 4.

What is the difference between multi-layer steel structure and single-layer steel structure

The characteristics of steel structure are: the heat resistance of steel structure is good, but the fire resistance is poor; the test shows that when the performance of steel changes from normal temperature to 150 ℃, the strength and plasticity of steel change greatly at 600 ℃, and the strength drops to zero , Completely lose the bearing capacity, and the fire resistance level of the steel structure is improved. When the fireproof coating thickness of the fireproof coating is 15mm, the fire resistance limit of the steel member can reach 1.5h.

 

1. Single-story: There is only one-story building on the ground, which is a single-story building, including industrial plants (single-story height above 6-8m), civil buildings (2-3m) and agricultural factory buildings (above 2.2m) and other buildings.

 

2. Multi-storey: Refers to 4-6 storey buildings.

 

3. High-rise: Refers to buildings with more than 10 floors and a total height of less than 100 meters.

 

4. Super high-rise: Refers to buildings with more than 40 floors and more than 100 meters.

 

5. High-rise buildings and super high-rise buildings mainly adopt steel-concrete structures, such as: cross columns, box columns and other structural forms.

 

The above is the introduction of SAFS steel structure to different places of multi-layer and single-layer. Steel structure is widely used today and is also loved by more builders.

Space frame manufacturer's transportation and storage requirements for craft accessories

       Before the process engineering, the space frame manufacturer will process the parts of the accessories.

After the coating of the accessory surface is dry, the space frame is checked in detail after drying the coating of the accessories. The surface coating of the packaging protection component is a complete drying state, ensuring that the components and parts are not deformed, damaged, and no loss.

The names, numbers, weights, and hanging points of the space frame of the space frame packaging, the name, number, weight, and hanging point position, etc., and fill in the packaging list.

In the installation order of the process attachment, the space frame structure accessories is assembled according to the unit, and the configuration is complete and re -supply. The stacking venue on the spot can meet the needs of the on -site installation order.

During the transportation of space frame accessories, the length and weight of the space frame craft accessories are combined with the appropriate transportation vehicles. The fulcrum of the space frame accessories on the transport vehicle, the length of the two ends, and the method of ligation must ensure that the space frame accessories do not produce deformation and not damage the coating.

The daily storage requirements of the craft accessories of the space frame to ensure that the ground floor is flat and firm. Divide and store according to the type, model, and installation order of the components; the bottom cushion should have sufficient support surface to prevent the fulcrum from sinking. When the same type of space frame accessories are stacked, the fulcrum of each layer of the space frame accessories should be kept on the same vertical line to prevent the space frame accessories from being fractured and deformed.

After the craft accessories to the construction site, the relevant personnel should check the details of the accessories, check the number of accessories entry accessories, and check the factory certificate and related information.

Features of the space frame structure

Space frame engineering is gradually increasing in people's daily life. As we all know, it is a space frame structure composed of several rods connected according to a certain network space. According to the appearance design of the product, there are flat space frame and inclined spherical space frame, showing the characteristics of the space frame structure of the interior space.

 

The spherical space frame has the characteristics of triple stress, and can bear various stress functions. Generally, the internal structure can be adjusted according to the force standard of the spherical space frame, and has a high safety factor. For the spherical space frame, this is the The rods at the intersection of the upper sky not only bear force but also have the function of pillars, ensuring the comprehensiveness of the space frame project, and the product has good stability, high rigidity and good seismic performance during use.

 

The space frame structure building project can realize the large-span structure of small rods to build large-scale projects. At the same time, the space occupied by the structure is relatively small, and the interior space can be used with greater efficiency.

 

The structure of the spherical space frame has very unique characteristics. It can carry out various stresses by changing the stress state, which greatly stimulates the strength of materials and reduces the consumption of materials. In addition, The raw material of the rods for manufacturing the space frame structure is relatively simple, which is conducive to transportation and storage, and is conducive to improving productivity and ensuring the quality of the project.

How to quickly build a steel structure warehouse

Many companies now plan to build new factories in order to meet production needs. From the perspective of construction costs, the steel structure warehouse is much lower than that of traditional factories, while the construction time is shorter. However, some people don't know much about the steel structure, and they don't know how to quickly complete the construction of the warehouse.

It is learned that it is not a problem to build steel structure factories quickly. First contact steel structure manufacturers. In recent years, with the accelerated development of the steel structure industry, many manufacturers have provided steel structure construction services. Under the same conditions, it is recommended to contact manufacturers with good reputation and brand influence in the industry. They have established construction specifications and have professional design and installation teams to meet user needs. The second is to speed up steel structure design. What kind of factory do you want to build?

Customers can refer to the existing steel structure model and make amendments to the dissatisfaction place. Finally, the construction of steel structure is strictly organized. From the perspective of construction, it involves the flat field and the installation of steel structure. In order to achieve continuity, each construction program is connected as much as possible, and at the same time, it is well collaborative. In fact, some professional steel structure manufacturers have a whole set of construction processes and installation steps. When customers determine the factory style, they will promote it in many ways and work together to complete the installation of the warehouse.

It is estimated that the construction cost of the steel structure warehouse is only about 40%of the traditional factory buildings, which can effectively reduce the production cost of the enterprise. Therefore, more and more enterprise users choose to build steel structures. As long as the above points are grasped, the construction speed of the steel structure has been significantly improved. If you have a plan to build a warehouse, you can contact the SAFS steel structure grid company. This is a regular company that provides steel structure design and installation services. Strong strength and recommended.

Steel structure factory roof characteristics

The roof of the steel structure factory building is generally relatively flat, because the steel structure factory building is usually relatively flat, and the area is relatively large, and it will not be said that there are some uneven or strange designs. The practicability of the uneven steel structure factory building is very poor, because the area of the steel structure factory building is generally larger than that of the ordinary factory building, so the uneven factory building structure

The body is not conducive to the application of steel structure workshops. It is precisely because of this that the roofs of many steel structure factories are designed to be flat, because the roofs of steel structure factories are still serving steel structure factories in essence. 

The heat dissipation of steel structure workshop roofs is generally better, this is also because the work performed in steel structure workshops is generally the kind of work that generates relatively large heat, such as some glass manufacturing or some light industries, This kind of steel structure factory building needs a lot of power support. When using a lot of electricity, it will generate a lot of heat. Therefore, when designing the roof of a steel structure factory building, it is generally considered to use materials with better heat dissipation , In addition, there are generally more people in steel structure workshops, so it is necessary to consider heat dissipation and ventilation from every angle as much as possible, because human breathing will produce carbon dioxide.

Principles to be Followed in Choosing Appropriate Space Frame Engineering Design Form

       There are many different forms for the design of space frame processing engineering, but depending on the environment, the selected form may be different. The following are the basic principles to be followed in the selection of space frame processing engineering:

1. Large-span space frame processing engineering: three-way cross space frame and triangular pyramid space frame are preferred;

2. Plane cross truss system: If the plane shape is square or close to square, it is better to adopt the orthogonal and upright form. When the plane shape is rectangular, the orthogonal and oblique form should be adopted. It is not recommended to adopt the oblique and oblique form.

3. The space frame of the quadrangular pyramid system is evenly loaded and has the best rigidity; the space frame is placed upright to save steel, which is convenient for lighting and ventilation, and the oblique and star shape are conducive to giving full play to the strength of the material.

4. When the planar shape is trigonal, hexagonal or circular, the triangular pyramid system space frame is the first choice. Among them, the triangular pyramid space frame has the highest rigidity, followed by the evacuated triangular pyramid, but it saves materials and has a simple structure, and the honeycomb shape has the worst rigidity. It should be combined with peripheral supports when selecting.

5. Selection of support mode: Peripheral support is suitable for large and mid-span space frames; point support is flexible in layout, suitable for factories and warehouses with large column spacing, and mixed support is suitable for hangars or assembly workshops. The selection of the space frame processing project is not a random choice. It should be considered according to many factors such as the environment and function of the site, so as to ensure that the space frame building can play its due value.

Metal arched roof slot connection method

According to the principle of differential division, a ring can be divided into several small units, and the difference between the width of each unit of each unit and the B2 is ΔB. This difference is processed into a wedge -shaped slot and connects two equal width plates together. This method is called a groove connection method. This method can be used to zero, and it is difficult to turn it. The use of existing ordinary equipment and technology can solve more complicated problems. Not only is it easy and feasible, but also reasonable, improve the utilization rate of materials and reduce waste. The inner arc length is the total length of the division, and the actual external width of the selected board type is divided into unit B2, and the corresponding outer circular unit arc length is B1. Selected wide straight boards, only one-way bending can meet the styling requirements. The difference between the internal and external units is Δb = B1-B2. The gap between the two boards can be suppressed into large, small cover grooves according to the selected plate -shaped ripple forming size. Pull tightly by pulling rivets on the side of the waves, or pull rivets at the valley. This method is applied in the engineering practice in recent years, and has achieved good social and economic benefits. The following is based on two typical projects to explain the choice of different shapes and different board types in detail, and the design and construction methods of the cover slot are also different.

After the above introduction, it can be seen that it can be seen that the groove connection method has great advantages at the hyperbolic level. The SAFS steel structure believes that this practice can be promoted and applied. It is particularly applicable to ordinary mid -range materials such as ordinary pressure steel plates. For high -end materials such as aluminum plates or aluminum alloy plates, direct forming method can also be used. The cost of such engineering is generally relatively high, the strength of the board is low, and it is easy to mold.

Main Factors of Steel Structure Damage and Its Reinforcing Technical Measures

 The main factors of steel structure damage are:

(1) Insufficient bearing capacity of the structure caused by load changes, extended service, and changes in codes and regulations;

(2) The component is deformed, twisted, disabled, dented, etc. due to various accidents, resulting in weakening of the section of the component, warping of the rod, cracking of the connection, etc.;

(3) Deformation, cracking and warping of components or connections caused by temperature difference;

(4) The cross-section of steel structural members is weakened due to corrosion caused by chemical corrosion and electrochemical corrosion;

(5) Others include mistakes in design, production, and construction, and illegal use and operation during the service period.

There are mainly three types of reinforcement technical measures for steel structures:

(1) Cross-section reinforcement method: Reinforce with steel in part or along the whole length of the member, and connect them into a whole to make them bear common force;

(2) Change the calculation diagram: add additional supports, adjust the load distribution, reduce the level of internal force, and force the displacement of the statically indeterminate structural supports to reduce the stress peak;

(3) Prestressed cable method: use high-strength cables to reinforce weak links of the structure or improve the overall bearing capacity, stiffness and stability of the structure.
