Installation and construction method of assembly type house building composite slabs

Abstract

The invention relates to the technical field of house building construction, in particular to an installation and construction method of assembly type house building composite slabs. The method includes the following steps of firstly, binding beams and rebars, and temporarily fixing first upper rebars of the beams to first sides of the upper portions of the beams; secondly, hanging second composite slabs on second sides of the upper portions of the beams, wherein the first sides and the second sides are located on the two sides of the beams correspondingly; and thirdly, fixing and binding thetemporarily-fixed first upper rebars after restoration. Since the first upper rebars and the second composite slabs are located on the different sides of the upper portions of the beams, when the second composite slabs are hung, and no position conflict occurs; anchoring rebars of the second composite slabs do not need to be bent, the tensile strength of the anchoring rebars cannot be affected, and meanwhile the after-installation structure quality is ensured; and since the first upper rebars are disposed for temporary fixation, the beams and the rebars are connected into a whole, the beams and the rebars are prevented from damage when the second composite slabs are installed, construction cost is prevented from being increased, and construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for installing and constructing prefabricated building construction laminated panels. Background technique [0002] At present, the following two solutions are mainly used to deal with the position conflict between the anchor reinforcement bars of the laminated slab and the upper reinforcement bars of the beam during the hoisting of the laminated slab in China: [0003] Option 1: Before hoisting the laminated slab, bend the anchor bars anchored into the beam upwards by 90°, and restore the bars after hoisting. [0004] Option 2: Bind the remaining steel bars of the beam except the upper steel bar first, and then complete the binding of the upper steel bars of the beam after the hoisting of the laminated slab is completed. [0005] However, there are problems with both of the above solutions: [0006] Option 1: The anchoring steel bar is bent twice, which ...

Problems solved by technology

[0006] Option 1: The anchoring steel bar is bent twice, which reduces the tensile capacity of the anchoring steel bar and affects the structural quality

[0007] Solution 2: When the beam reinforcement is bound, the upper reinforcement of the beam is not bound, and the overall closure cannot be achieved. The overall beam reinforcement is not stable. The beam reinforcement is easy to be damaged during the hoisting of the laminated slab, and the repair of the beam reinforcement will reduce the construction efficiency and increase the construction cost; the composite slab is hoisted. The upper reinforcement of the rear beam has bent anchors. After the laminated slab is installed, the upper L-shaped reinforcement of the beam is tied. It is difficult to set it in place and the construction is difficult.
