Abstract

The invention discloses a construction installation method for a fast-easy setback grid of a bottom plate construction joint, comprising the following steps of: (a) respectively installing an upper-layer reinforcing grid and a lower-layer reinforcing grid on the top surface and the bottom surface of the bottom plate construction joint; (b) installing a water-stop steel plate between the upper-layer reinforcing grid and the lower-layer reinforcing grid; (c) welding a plurality of upper-layer vertical reinforcing bars sequentially and longitudinally at intervals along the construction joint between the upper-layer reinforcing grid and the water-stop steel plate, and welding a plurality of lower-layer vertical reinforcing bars sequentially and longitudinally at intervals along the construction joint between the lower-layer reinforcing grid and the water-stop steel plate; and (d) respectively binding and connecting the upper part and the lower part of the fast-easy setback grid with the upper-layer reinforcing grid and the lower-layer reinforcing grid, and binding and connecting side walls of the fast-easy setback grid with the plurality of upper-layer vertical reinforcing bars and the plurality of lower-layer vertical reinforcing bars. By adopting the method provided by the invention, leakage is difficult to occur in the concrete pouring process, fewer steps are needed, the construction period is short and the comprehensive cost is low.

Description

technical field [0001] The invention relates to a construction and installation method of a fast and easy closing net, in particular to a construction and installation method of a quick and easy closing net for construction joints of a bottom plate. Background technique [0002] Kuaiyi Closing Net is a permanent formwork successfully developed in the early 1980s. It is a formwork made of thin hot-dip galvanized steel sheet and processed into a formwork with unidirectional U-shaped ribbed framework and unidirectional three-dimensional network. Its mechanical properties are excellent, and it is light and heavy. In addition, the fast and easy closing net does not need to be demolished. It is especially suitable for pouring concrete in sections, and has advanced science and wide practicability. However, there are also certain shortcomings, that is, the quick-easy closing net is easy to deform and leak grout under the extrusion of concrete, so that the compactness of concrete is...
