Basement floor post-cast strip structure and construction method thereof

Abstract

The invention provides a basement floor post-cast strip structure and a construction method thereof. The structure comprises a cushion layer, a V-shaped water-stop steel plate, post-cast strip steel bars, post-cast strips, floor steel fabrics, a floor and a waterstop; the center of the cushion layer is fixedly provided with the V-shaped water-stop steel plate through screws; the post-cast strip steel bars are welded to welding sections of the two sides of the V-shaped water-stop steel plate; the post-cast strip steel bars are attached to the top surface of the cushion layer and extend upwardsalong a downwards-concave slope of an inverted trapezoid; the welding sections of the V-shaped water-stop steel plate are provided with upright templates; the post-cast strips are cast on the two sides of the templates; the post-cast strips cover the two sides of the V-shaped water-stop steel plate and the post-cast strip steel bars; the floor steel fabrics are arranged on the top surface of the cushion layer and the top surfaces of the post-cast strips; the floor is poured with a floor steel fabric as a foundation; the middle portion, corresponding to the inverted trapezoidal downwards-concave width, of the floor is provided with a fracture; and the waterstop is embedded in the center of the fracture section.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to a basement basement post-cast belt structure and a construction method thereof. Background technique [0002] The post-cast belt construction technology is widely used at the construction site. The traditional post-cast belt retention method is to pour the post-cast concrete after the construction of the main structure is completed. This requires continuous precipitation to ensure that the groundwater level remains below 500mm of the foundation. After the main structure is completed, the concrete is poured after pouring and the concrete strength meets the design requirements before the precipitation can be stopped. The overall construction time is longer; and the traditional The post-pouring tape technology will increase the cost of project dewatering and damage the waterproof layer of the bottom plate when the groundwater pressure is strong, resulting in the failure of the ...

AI Technical Summary

Problems solved by technology

This requires continuous precipitation to ensure that the groundwater level remains below 500 mm of the foundation. After the main structure is completed, the concrete is poured after pouring and the concrete strength meets the design requirements before the precipitation can be stopped. The overall construction time is relatively long; and the traditional The advanced post-cast belt technology will increase the cost of project dewatering and damage the waterproof layer of the bottom plate when the groundwater pressure is strong, resulting in the failure of the post-cast belt waterproof layer; the long-term immersion of the post-cast belt steel bars and construction joints in water will affect the construction quality of the subsequent concrete pouring process , the foundation pit cannot be backfilled early, affecting the safety of foundation pit support and the early use of temporary land
