Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] see Figure 1-2 , the present invention provides a technical solution: a post-cast joint structure and construction method of a laminated slab, the specific operations are as follows:

[0026] Step 1: Measure and set out, set up beams or walls, and post-cast joint formwork system. The post-cast joint formwork system is mainly composed of steel pipes, square wood, adjustable jacking, multi-layer plywood and self-adhesive rubber sealing stri...

Abstract

The invention discloses a laminated slab post-pouring joint structure and a construction method, and relates to the technical field of building construction. The laminated slab post-pouring seam structure and the construction method specifically comprise the following steps that firstly, surveying and setting out are conducted, a beam or a wall and a post-pouring seam formwork system are erected, and the post-pouring seam formwork system is mainly composed of a steel pipe, square timber, an adjustable jacking, multiple layers of plywood and self-adhesive rubber sealing strips; the self-adhesive rubber sealing strip can be adhered to the template, is good in sealing performance, and can be recycled for multiple times after the template is removed. According to the laminated slab post-pouring joint structure and the construction method, the contact face of the straight section of a traditional prefabricated slab is optimized into a structure with the narrow left portion and the wide right portion, the end of the prefabricated slab and the formwork form a reserved groove, an inverted-T-shaped structure is formed after concrete pouring, the overall shape of the prefabricated slab and a cast-in-place layer is increased, the shape is divided into oblique steps, concrete pouring and vibrating compaction are facilitated, and the model reduces the concrete pressure at the slurry leakage position and reduces the slurry leakage rate.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a post-cast joint structure of a laminated slab and a construction method. Background technique [0002] The prefabricated building is a benign interaction between the traditional construction industry and advanced manufacturing industry, and is the product of the deep integration of construction industrialization and construction informatization. Promoting the development of prefabricated buildings is of great significance to promoting the transformation of construction production methods, ensuring the quality and safety of engineering construction, promoting the transformation and upgrading of the construction industry, and supply-side structural reforms. The laminated slab is the most widely used assembly structure in prefabricated buildings. It is an assembled monolithic floor slab formed by laminating prefabricated slabs and cast-in-place reinforced concrete la...
