Basement-roof-post-pouring-belt pre-closing structure and construction method

Abstract

The invention relates to a basement-roof-post-pouring-belt pre-closing structure. The basement-roof-post-pouring-belt pre-closing structure comprises a basement-roof-post-pouring-belt pre-closing lateral model structure, a basement-roof-post-pouring-belt pre-closing flush-type prefabricated plate structure and a basement-roof-post-pouring-belt pre-closing suspending-model jacking pouring structure; the basement-roof-post-pouring-belt pre-closing lateral model structure comprises comb-type lattice-type skeletons, expanded steel diamond meshes, steel wire dense meshes, vertical reinforced steelplates, water-stopping steel plates, horizontal supporting rods, slant iron wire support rib pulling rods and straight thread sleeves; the basement-roof-post-pouring-belt pre-closing flush-type prefabricated plate structure comprises post-pouring-belt main ribs, an upper ribbed prefabricated plate, foam plates, connecting threaded rods, deformation adjusting gaskets and hauling threaded rods. Thebasement-roof-post-pouring-belt pre-closing structure has the advantages that accurate positioning and fixing of the comb-type lattice-type skeletons, the expanded steel diamond meshes, the steel wiredense meshes, the vertical reinforced steel plates and the water-stopping steel plates are achieved, and meanwhile the horizontal supporting rods and the slant iron wire support rib pulling rods aremore easily arranged.

Description

technical field [0001] The invention relates to a basement roof pre-closed post-pouring tape structure and a construction method, which belongs to the field of basement post-pouring tape sealing engineering, is suitable for the construction of high-rise buildings and super-long concrete structures, and is very good for buildings with tight construction periods and high settlement requirements. Effect. Background technique [0002] In high-rise buildings, the high-rise main building and the low-rise podium are often connected together. Due to the large basement area, the post-cast belt is set up to overcome harmful cracks caused by concrete shrinkage and foundation settlement. However, the post-cast belt has a large section and Due to the dense reinforcement, it is extremely difficult to support the formwork, especially if some sundries or garbage fall into it, and it cannot be closed for a long time, and it cannot be covered with soil in time, which has a great impact on the...

[0002] In high-rise buildings, the high-rise main building is often connected with the low-rise podium. Due to the large basement area, the post-cast belt is set up to overcome harmful cracks caused by concrete shrinkage and foundation settlement. However, the post-cast belt has a large cross-section and Due to the dense steel reinforcement, it is extremely difficult to support the formwork, especially if some sundries or garbage fall into it, and it cannot be closed for a long time, and it cannot be covered with soil in time, which has a great impact on the quality of the structure

In the traditional construction method, the post-casting belt is set separately when the frame is erected. After the post-casting belt meets the design requirements, it is poured with a higher-strength concrete. This will cause the post-casting belt to be closed for a long time, which will affect the quality of the project. carry out
