Building formwork slab-staggering-prevention abutted seam connection method

Abstract

The invention relates to a building formwork slab-staggering-prevention abutted seam connection method. The method is characterized by comprising the following steps that S1, an abutted seam fastening device is machined; S2, formworks are selected, specifically, building formworks with proper sizes and quantity are selected according to a site needing to be laid, and positioning mounting holes are drilled in the four side surfaces of each building formwork at intervals; S3, assembling is carried out to form a new assembly type circulation formwork, specifically, a limiting plug block and a limiting bearing block, machined in the S1, of the abutted seam fastening device are mounted at the two opposite sides of the bottom face of each building formwork with the positioning mounting holes drilled in the S2 through bolts, and the new assembly type circulation formwork is formed; S4, a plurality of new assembly type circulation formworks formed in the S2 are laid and spliced; and S5, a movable rod on the abutted seam fastening device slides towards the other side to achieve splicing of the adjacent formworks. The flatness of the abutted seam of a splicing formwork is guaranteed, the concrete pouring quality is improved, meanwhile, the splicing and dismounting efficiency is high, the construction period is shortened, and the circulation service life of the formworks is prolonged.

Description

technical field [0001] The invention belongs to the technical field of construction, and relates to a building formwork patchwork technology, in particular to a building formwork patchwork connection method for anti-stacking. Background technique [0002] Existing concrete structures use a large number of formworks during construction. Due to the size limitation of the formwork, multiple formworks are required to be spliced ​​together, thus facing common problems such as seam leakage, wrong platform, etc., which have always affected the quality of engineering construction and the work site. environment; therefore, many projects solve the problem of staggered platforms by screwing connection bars between adjacent building formworks. However, building formwork needs to be assembled and disassembled repeatedly during engineering construction. This connection method is likely to cause damage to the formwork and turnover. The efficiency is reduced, and the construction time is gr...

Problems solved by technology

[0002] Existing concrete structures use a large number of formworks during construction. Due to the size limitation of the formworks, multiple formworks are required to be spliced ​​together. As a result, there are common problems such as seam leakage, wrong platform, etc., which have always affected the quality of engineering construction and the work site. environment; therefore, many projects solve the problem of staggered platforms by screwing connection bars between adjacent building formworks. However, building formwork needs to be assembled and disassembled repeatedly during engineering construction. This connection method is likely to cause formwork damage and turnover. The rate is reduced, and the construction time is greatly increased, which increases the construction cost.
