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.
