Description

Technical Field

[0002] The reverse construction method is used for underground space development of cultural relics protection buildings. Before the underground space development, the cultural relics protection buildings must be lifted up first, and then the excavation and construction of the basement roof must be started. After the basement roof is completed and reaches the strength, the cultural relics protection buildings are lowered, and then the internal structure of the cultural relics protection buildings is constructed. In this case, there are many cases of one column and one pile. When falling back, the lattice columns cannot be exposed to the ground, thus affecting the falling back of the building, so it is impossible to use the method of connecting steel columns after they are higher than the floor. The most complicated situation is that the one-column-one-pile lattice columns also serve as lifting structure supports.

[0003] However, the lattice column is connected to the upper steel column. The usual possible implementation method is to add a head end plate to the end of the lattice column, and then weld the upper steel column to the end plate to form the upper vertical structure. This method connects the temporary structure and the permanent structure only through an end plate. From the perspective of structural design, the force is not clear, and the lattice column cannot be strictly regarded as the anchoring of the upper steel structure in the concrete; from the perspective of construction, the temporary lattice column needs to ensure that all welding is first-class welds, and at the same time, a stiffening partition needs to be added to the inside of the lattice column. It is difficult to implement the existing structure. Therefore, a conversion device for box-type steel columns and lattice columns is urgently needed to solve the above problems.
