Template positioning tool and method for external wall concrete cornice pouring

Abstract

The invention discloses a template positioning tool and method for external wall concrete cornice pouring. Through the production, installation and reinforcement of a shaping mold, a component formedby pouring is not plastered, the construction period is saved, the cost is reduced, and the construction quality is ensured. The tool comprises cornice templates formed for pouring concrete and support frames at the lower parts of the cornice templates. Each of the cornice templates is a long template with an L-shaped cross section and is divided into a flat plate and a vertical plate, and the cornice templates and the support frames are installed together by dovetail screws. Each of the cornice templates corresponds to a plurality of support frames. The support frames are installed on an outer wall by expansion bolts. The heights of the vertical plates of the cornice templates are consistent with the heights of upper vertical segments of the support frames. The widths of the flat plates of the cornice templates are larger than the lengths of horizontal segments of the support frames. Through the use of the tool, the process of strengthening a cast-in-place concrete component templateis simplified, and the tool is simple and efficient and has a good application value.

Description

technical field [0001] The invention relates to a formwork positioning tool and method for pouring concrete overhanging eaves on an exterior wall, belonging to the technical field of construction engineering. Background technique [0002] Concrete overhanging eaves on exterior walls refer to strip-shaped cast-in-place moldings formed by concrete pouring, which are used to separate and decorate buildings. Overhanging eaves are non-load-bearing components, requiring straight and beautiful lines and consistent heights to achieve the effect of decoration and beautification. The conventional method is to construct the exterior wall at the same time. Due to the limitation of the work space and technical requirements of the exterior wall, it is often necessary to carry out secondary chiseling repairs and plastering due to the poor level of the overhanging eaves and the unsatisfactory surface quality.

AI Technical Summary

Problems solved by technology

The conventional method is to construct the external wall at the same time. Due to the limitation of the working space and technical requirements of the external wall, it is often necessary to carry out secondary chisel repair and plastering due to the poor level of the overhanging eaves and the unsatisfactory surface quality.

[0003] When making fair-faced concrete overhangs, straightness, levelness, surface perception and pollution are all important considerations. However, the following problems exist in actual construction: 1. Different decoration methods have different handover parts, and there are difficulties in process handover; 2. In the actual operation process, it is difficult to control the levelness of the concrete eaves; 3. The concrete eaves are located on the outside of the outer wall, with a height of 3m-6m from the ground, and it is difficult to reinforce the overhanging eaves with formwork; 4. The outer wall splits bricks and During stone construction, it is easy to damage the edges and corners of the concrete eaves, which is not good for the protection of the finished eaves
