Problems solved by technology

[0003] The existing construction methods cannot meet the requirements of construction safety, quality and progress at the same time, and have the following disadvantages:
[0004] First, the demolition process of the partition wall is relatively cumbersome. The partition wall is removed in layers and sections, and then the connection of the structure of the layer is completed. The whole process needs to go through the demolition of the partition wall, the transportation of garbage, the erection of formwork and the connection of the structures on both sides and other stages, due to the overlap of construction procedures, the entire construction period takes a long time;
[0005] Second, for the beamless floor, due to the separation of the partition wall, the floor slabs on both sides of the ground wall are cantilever structures. This construction process is often not considered in the structural design, and danger may occur during the removal of the partition wall and the structural connection of the two sides. or cause quality accidents;
[0006] Third, the middle partition wall is removed in layers from the top, and then the structures on both sides are connected in layers. The connection of the top structure causes the ground wall garbage that is subsequently removed to be transported outside the site through vertical transportation, but needs to be re-transported by truck , resulting in increased construction costs and pollution to the surrounding environment

Embodiment 1

[0031] Such as figure 1 As shown, in this embodiment, the partition wall 1 is removed in sections, and then the corresponding floors of the structures on both sides of the partition wall 1 removal area are connected. When the partition wall 1 is removed twice in two sections, the partition wall 1 is divided into the partition wall 11 in the first zone and the partition wall 12 in the second zone, and the construction of the demolition of the partition wall 1 and the structural connection on both sides method, comprising the steps of:

[0032] Such as figure 2 As shown, S001: Temporary structural columns 2 are set on both sides of the partition wall 1;

[0033] Such as Figure 3 to Figure 4 As shown, S002: After the construction of the structures on both sides of the middle partition wall 1 is completed, cut and chisel the middle partition wall 1 in sections, lift the removed middle wall garbage, and connect the bottom, floor and roof of the structures on both sides, so tha...

Abstract

The invention relates to a construction method for middle wall dismantling and two-side structure connecting, and belongs to the technical field of building construction. The construction method is used for solving the problems that the construction period is long, construction difficulty is large and the surrounding environment is polluted due to the fact that two-side structures are connected only after the middle wall is dismantled in a layered and sectioned mode in the prior art. The construction method for middle wall dismantling and two-side structure connecting comprises the steps that 1, temporary constructional columns are arranged on the two sides of a middle wall and serve as supports of temporary overhanging portions of the two-side structures before the middle wall is dismantled; 2, after construction of the two-side temporary constructional columns is completed, the middle wall is dismantled by cutting in sections, and dismantled ground wall rubbish is transported by a crane; 3, bottom plates of the two-side structures and floor slabs and top plates of various floors are connected, so that the two-side structures are connected into an integral structure; and 4, the temporary constructional columns are dismounted in a layered mode from bottom to top.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for removing a middle partition wall and connecting structures on both sides. Background technique [0002] Before the construction of the foundation pit adjacent to the subway line, in order to protect the safe operation of the subway line, a partition wall (a partition wall is a type of underground continuous wall) must be installed at a certain distance from the subway line. The partition wall divides a basement into two parts , the structures on both sides are constructed separately, and finally the ground wall is removed to connect the structures on both sides. [0003] The existing construction methods cannot meet the requirements of construction safety, quality and progress at the same time, and have the following disadvantages: [0004] First, the demolition process of the partition wall is relatively cumbersome. The partition wall is ...
