The comparison of the dome support of the shallow round warehouse and the traditional construction technology

Through the comparison of traditional silo roof measures and platform construction schemes, in view of the characteristics of the large span of the silo and the high-altitude operation, the current dome support construction technology can well solve the shortcomings of the traditional technology, which not only saves the cost but also ensures the construction operation. safety. The following is aboutShallow Dome BracketThe description of the construction, I hope it will be helpful to everyone.

The traditional construction technology of the silo roof is to use the pre-embedded corbel platform as the construction platform for the superstructure after the steel slipform platform is completed. However, the actual operation requires not only the platform itself to have sufficient bearing capacity, but also reliable stability. There is also a considerable hidden danger to the safety of the operator when the lowering platform is operated on the top of the warehouse wall behind the sliding form. Secondly, it is not time-consuming, labor-intensive and unsafe to dismantle the platform. Therefore, the traditional platform sliding form construction is due to its dismantling risk. The larger has been gradually abandoned.

Another is to use the sliding form to tow the girder, and put the design structure girder on top of the sliding form gantry. After the sliding form construction is completed, remove part of the platform to lower the girder to the design elevation with inverted chains. The structural girder is only one-rolled steel. The frame can reach more than ten tons, but it is still necessary to design the upper part of the wall thickness to reduce or the lower wall thickness to increase, increase its cost or reduce the structural safety. The inverted chain that lowers the girder to the design elevation is also a safety problem that is difficult to solve.

In addition, the measure platform is installed after the slipform construction is completed. Generally, the embedded parts of the tube wall and the small platform are used, and the tower crane is used to lift the platform beams piece by piece. There is considerable operational risk.

The above traditional construction methods will increase risks and costs. Therefore, designing a support similar to the silo roof structure and passing the stability verification can solve the shortcomings of the traditional technology. The construction technology of the silo dome support is widely used in the construction of the silo roof. For more details, please consult Anhui Xingcheng Slipform Engineering Co., Ltd.
