Occlusion structure of stepped deformation joints on high and low roofs

Abstract

The invention provides a high-low roof stepped deformation seam occlusal structure, by setting staggered cantilevered reinforced concrete slab cover plates at the high and low positions of the roof stepped deformation joints and protruding from the high and low-level reverse sills respectively, and A vertical plate is set on the surface of the deformation joint at the drop, and the bottom of the vertical plate is connected to the top surface of the lower horizontal cover plate close to the deformation joint at the drop, and the side is connected to the high-order reverse sill on the same side as the lifting end of the lower horizontal cover plate. A continuous step-shaped deformation joint is converted into a continuous three-dimensional four-way deformation joint, which solves the problem that the roof catchment water on the higher roof structural plate crosses the lower horizontal cover plate and flows backward to the deformation joint at the drop. The roof structural slab, cover slab, vertical slab, anti-sill and side beams are all poured with reinforced concrete, so that the main structure, waterproof seal, thermal insulation material and other deformation joint structures can be formed continuously and integrally, which simplifies the construction formwork and reduces the construction cost. Difficulty, shorten the construction period.

Description

technical field [0001] The invention relates to a general building structure for joints, in particular to a high and low roof stepped deformed seam joint structure. Background technique [0002] Deformation joints are artificially set gaps of appropriate width to prevent deformation of buildings under the action of external factors (temperature changes, uneven foundation settlement and earthquakes), resulting in cracking or even destruction. [0003] In architectural design, due to the appearance, functional requirements or structural characteristics of the building, it will lead to the formation of such figure 1 The high and low roof structure shown includes two side beams 1, and two roof structure panels 2 with a height difference between them are respectively fixed on the outer sides of the two side beams 1, and steps are arranged on the two side beams 1 Type anti-sill 3, there are gaps between the two stepped anti-sills 3 and between the two side beams 1, and the two ga...

Problems solved by technology

[0006] (1) The structure of the deformation joint is segmented and discontinuous. Whether it is the construction between the cover joint plate and the main body of the building, or the waterproof sealing inside the deformation joint, and the construction of the coil, it is difficult to carry out continuous and unified treatment, which increases the difficulty of construction. and construction period;

[0007] (2) shaped like figure 1 The high and low roof structure, because the reinforced concrete roof structure slab on the left is lower than the reinforced concrete roof structure slab on the right, if the image 3 The structural form of the structure makes it difficult to drain the rainwater into the reinforced concrete roof structural slab on the right side in the event of heavy rain;

[0008] (3) Since the joints between them are filled with sealant, if the sealant, flat seam cover and special end cover are exposed to the environment for a long time, they will age and crack, and the rainwater will be directly poured into the The interior of the building is caused by deformation joints, resulting in water seepage and leakage
