Problems solved by technology

Therefore, during the construction of the basement structure, due to the block construction of the floor slab, the area of ​​the floor slab adjacent to the enclosure structure is too small to withstand the pressure transmitted by the enclosure structure when the support is disassembled, resulting in large displacement or deformation, affecting The safety of the main structure in the dismantling area may even lead to the destruction of the main structure
[0004]At present, there is no effective measure to solve this problem. Only after the post-cast belt is fully constructed can the support of the enclosure structure be removed, which limits the construction order, or even delay the construction period, affecting the construction progress

Embodiment Construction

[0020] The present invention is specifically implemented in the Hangzhou Wantong Center project to be developed and constructed by Hangzhou Wantong Fashion Property Co., Ltd.

[0021] The project site is located at the intersection of Shangtang Road and Daguan Road, Gongshu District, Hangzhou City. The proposed buildings for the project mainly include five 14-24-story buildings, with an integral underground garage with 3 floors. The proposed building on the site is a frame core tube structure. Due to the small range of the basement floor, support structures are provided in both the floor and the floor. Such as figure 2 As shown, on the bottom slabs on both sides of each post-pouring belt 7, the floor 5 is constructed first and the floor 6 is constructed after the upper reinforcement 1 of the inner bottom and the lower reinforcement 2 of the bottom is pre-embedded. Before the structural support, the steel backing plates 3 on both sides of the post-cast belt 7 are connected b...

Abstract

The invention provides a post-cast strip replacing supporting structure used for disassembling a building envelope support. The post-cast strip replacing supporting structure is composed of angle steel (4) and steel base plates (3). The steel base plates are embedded into the symmetrical positions of the middles of floors on two sides of a post-cast strip in advance. The angle steel is vertically installed between the two symmetrical steel base plates in the length direction. The angle steel and the steel base plates are connected in a welded mode before the building envelope support is disassembled. By the adoption of the replacing supporting structure, pressure generated by a building envelope in the support disassembling process can be effectively transmitted, and the safety of a body structure is ensured; moreover, when the post-cast strip is cast, the angle steel and the steel base plates do not need to be disassembled, and follow-up construction is facilitated. The replacing supporting structure is low in manufacturing cost, simple, easy to implement and wide in application range, and has high application and popularization value.

Description

[0001] technical field [0002] The invention relates to a post-cast belt support replacement structure used when the support of an enclosure structure is removed, and belongs to the technical field of underground engineering structure construction. Background technique [0003] Usually in the construction process of construction projects, in order to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven temperature and shrinkage, according to the requirements of design or construction specifications, it is necessary to leave temporary construction joints at the corresponding positions of the foundation floor, walls, and beams. The structure is divided into several parts for construction, and after the concrete components of each part solidify and shrink and stabilize, then post-cast belts such as construction joints are poured to connect the structure into a whole. Therefore, during the construction of the basement structure...
