Influence of temperature difference on steel space frame structure construction engineering

What are the effects of temperature difference on steel space frame structure construction projects? The phenomenon of thermal expansion and contraction of objects has obvious influence on the installation of column components in steel space frame structure buildings. The independent steel column hoisted on the column foundation is exposed to sunlight, causing it to have front and back sides, and there is a temperature difference on both sides and deformation, which will cause the steel column to tilt. As time goes by, the steel columns tilt westward in the morning and eastward in the afternoon. The steel columns of large steel structure workshops, commercial steel structure buildings, and municipal steel structure buildings all have the phenomenon of vertical changes. In the measurement adjustment, pay attention to the following points:

1. Distinguish whether the component is the original bending or the bending caused by the weather, so as to prevent unnecessary repeated adjustment;

2. You can choose to adjust the measurement in the morning or at night (of course, cloudy days without temperature difference are better) to eliminate the existence of temperature difference;

3. Or establish a column as a standard column, install it when there is no temperature difference, and correct its verticality deviation to ±0. When calibrating other columns, the verticality of the standard column shall prevail. Re-calibrate other steel columns to make their vertical values and inclination directions consistent with those of standard columns;

4. Or use the temperature difference displacement value formula to calculate the displacement value, so as to correct the displacement of the column end, and the direction can be consistent with the calculation.

Five advantages of Chinese space frame structure manufacturers

In recent years, due to the rapid development of electronic computing technology, the calculation problem of high-order statically indeterminate structures of steel structure space frames has been solved, and the development trend of steel structure space frames in both the formal level and the specific application level is the same.

At this stage, the focus is on large and medium-span commercial buildings, such as gymnasiums, hangars, exhibition halls, waiting rooms, gas stations, coal bunkers in power plants, etc. Large and medium-sized workshops have been gradually applied and promoted. The greater the distance, the more obvious the advantages of choosing this construction method and the practical effect of economic development.

China's space frame structure factory has five major advantages:

1. The manufacturer will actively contact the whole process of multi-channel processing technology such as flat roof, home improvement ceiling, stairway, civil engineering, water and electricity, anti-corrosion and thermal insulation engineering related to this construction project, so as to help you feel at ease and labor-saving;

2. Will actively review the rationality of the space frame engineering drawings you give, and give you clear opinions and suggestions on the results of the combing, you only need to make strategic decisions;

3. The manufacturer will reasonably arrange the construction period and do a good job of frame-line construction;

4. The manufacturer will provide complete raw material acceptance for the entire project;

5. China's space frame structure manufacturers will provide tracking and after-sales maintenance service project tracking services in the whole process of new project application in the later stage of the space frame project.

How to Tighten the Dry Coal Shed Space Frame Bolts

SAFS Space Frame Bolt Ball

1. In the middle and late application of the dry coal shed space frame, the corrosion resistance of its own stainless steel sheet is weak, because it is impossible to completely block the gas with architectural coatings on the construction site, and it is in a closed and restricted space, accumulating The unique chemical substances such as coal also have many uncertain factors, which cause and accelerate the corrosion of the steel structure.If there is a lack of timely maintenance measures during application, and in the whole process of application, if you do not pay attention to the extrusion of the rubber bearing and the bending of the components caused by the stacking pressure of coal, this will give safety to different levels. lead to a safety hazard or an immediate accident.

2. At the construction site of the space frame of the dry coal shed, in order to control the cost or not attach great importance to the construction party, the construction party will not carry out the engineering construction or timely engineering construction of the fireproof material for the surface layer of the steel structure. The heat resistance of stainless steel sheet is weak, and many of its properties change with the rise and fall of temperature. When the temperature reaches 430-540 °C, the yield limit, compressive strength and elastic mold of the stainless steel sheet will be greatly reduced, and the bearing capacity will be lost.

Steel structure manufacturers analyze the effects and disadvantages of steel structure buildings

What is the effect of steel structure manufacturers' steel structure buildings? What drawbacks need to pay attention to? We often see elegant streets in movies, with quaint but elegant buildings. This kind of building is built with wood structure or light steel structure, but now with the continuous rise of wood price, the market of light steel structure system gradually grows rapidly and is gradually widely accepted by the market, which is called building system.

steel structure buildings 

Steel structure is currently controversial as a prominent architectural form. Of course, there has also been a lot of negative news. It is not without news that steel buildings are degraded or collapsed. This has led many to suspect that the thermal conductivity of steel structures is large.

 

Such as composite board, insulation board, PVC and so on. The melting point of steel is 1400~1500, and the softening temperature of steel is about 500. When building temperatures hit around 500, it's not something we need to think about anymore. The steel structure is covered with fireproof gypsum board on both sides of the wall and the ceiling of the floor, and is protected with gypsum board on the ordinary fire wall and basin parapet, which can meet the fire protection requirement of one hour. The glass fiber filled between the wall and the wall column floor grid also has a positive protective effect on fire prevention and heat transfer.

 

If you insist that the fire protection effect of steel structures is not good, it is only a one-sided analysis, and you want to judge the fire performance of steel structures, not the fire performance of individual materials. After all, steel structure buildings are not made of steel plates, composite panels, thermal insulation surfaces, and PVC, but various materials are designed and perfected. In fact, many steel structures seem to be flammable substances. Why does every factory say that the fire resistance rating of steel structures is four, because it is impossible for anyone to use flammable substances to build houses.

 

In the sense of environmental protection, the steel structure is a green building, it is a dry work, does not require a lot of water, and will not waste water resources, no construction waste will be generated during the construction process, no noise, and the most important thing is steel The structure is a recyclable material, which greatly reduces the loss of resources.

 

Generally, all building materials of steel structures must be customized in advance in the factory, and after assembly, they can be directly pulled to the site for modular assembly. So it saves a lot of time required to build the steel structure.

steel structure construction 

In the construction process of steel structure, a lot of materials are used in thermal insulation, fire prevention, sound insulation, etc., so it is not only suitable for residential convenience, but also has advantages in steel structure industrial buildings, and the plasticity of steel structure is relatively strong,The shapes are also varied.
