Construction method for fixing trapezoidal column cap formwork

Abstract

The invention discloses a construction method for fixing a trapezoidal column cap formwork. The method comprises the following steps of firstly, splicing and installing the trapezoidal column cap formwork according to a design drawing; adopting triangular square wooden blocks for reinforcing the joints between the trapezoidal column cap formwork and a floor slab formwork, making each whole squarewooden block cling to the tail end of each triangular square wooden block, and adopting a single steel pipe for hooping each column module, wherein the single steel pipes are positioned on the bottomsurfaces of the whole square wooden blocks, and single steel pipe hoops are arranged at intervals and vertically supported; adopting the square wooden blocks for carrying out fan-shaped wrapping on joints in the four sides of the trapezoidal column cap formwork; adopting double steel pipe hoops for square wooden blocks wrapped in a fan shape; arranging inclined supports to reinforce the double steel pipe hoops, and connecting the bottoms of the inclined supports with a scaffold. The method avoids slurry leakage, die deviation and die bursting during concrete pouring, ensures the squareness ofthe corners of a trapezoidal column cap, improves the concrete forming effect, and saves die supporting materials.

Description

technical field [0001] The invention relates to a construction method for fixing a trapezoidal column cap template. Background technique [0002] In the construction process of the trapezoidal column cap formwork of the beamless floor, 50×100mm square timber is usually used to reinforce the formwork, and the 50mm side of the square timber is vertical to the column cap formwork, and the upper connecting plate is used to support the square timber, and the lower part of the square timber is connected to the column. Connected; after the square wood is arranged at an interval of 300mm, it is horizontally reinforced with a φ48 steel pipe at an interval of 300mm, and finally the vertical support of the steel pipe is reinforced at an interval of 300mm. The traditional reinforcement method has the following problems: [0003] ① The joints between the column cap formwork, the column formwork and the floor formwork are not reinforced, and problems such as grout leakage and mold explos...

AI Technical Summary

Problems solved by technology

[0003] ① The joints between the column cap formwork, the column formwork and the floor formwork are not reinforced, and problems such as grout leakage and mold explosion are prone to occur when pouring concrete, resulting in honeycomb pockmarks and irregular corners, which affect the concrete molding effect;

[0004] ②The joints of the formwork on the four sides of the column cap are not reinforced, and the joints are prone to be too large. When pouring concrete, problems such as grout leakage, mold runout, and mold explosion are also prone to occur, resulting in honeycomb pockmarks and irregular corners, which affect concrete molding. Effect;

[0005] ③ The square timbers are vertically arranged in parallel, not optimized for the formwork of the trapezoidal column cap, wasting materials;

[0006] ④Using vertical support, not optimized for the trapezoidal column cap. When pouring concrete, the vertical support is subjected to oblique force, and the vertical support is prone to deformation, which leads to problems such as mold runout and mold explosion, and the corners of the column cap are not square. , affect the concrete forming effect
