Template for large-volume concrete casting

Abstract

The invention provides a template for concrete casting, and particularly provides a template applied to the field of large-volume concrete casting. An embedded part (1) of a casting template is buried on the ground; a plurality of vertical rods (2) are arranged at intervals and form a frame structure on the ground; each vertical rod (2) is fixedly connected with the embedded part (1); a plurality of panels (3) are respectively connected with each side face of the frame structure consisting of the vertical rods (2); and each panel (3) is respectively and moveably connected with the vertical rods (2) close to the panel (3) through connecting pieces (4). The structure of the casting template has the advantages of high rigidity and stability, small deformation amount and the like, and the requirement on cross section size can be met during large-volume concrete casting; and because a Wisa plate serves as a concrete panel and has a certain water-absorption and exhaustion effect, the glossiness and the flatness of the surface of the cast concrete can be improved, and the casting quality of concrete is greatly improved.

Description

technical field [0001] The invention belongs to the field of mass concrete pouring, and more specifically relates to a template for mass concrete pouring. Background technique [0002] Concrete is one of the most important civil engineering materials today. It is an artificial stone made of cementing materials, aggregates (also called aggregates) and water prepared in a certain proportion, stirred and vibrated, and cured under certain conditions. Concrete has the characteristics of abundant raw materials, low price, and simple production process. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. With the maturity of concrete construction technology, the size of concrete solid section is also increasing, and mass concrete pouring has been used more and more widely. The pouring of mass concrete requires good formwork construction. According to the materials, the formwork engineering is ...

AI Technical Summary

Problems solved by technology

Existing formwork projects have many deficiencies in mass concrete construction. In mass concrete construction, steel formwork has good rigidity and is not easy to deform. It can ensure that the section size meets the requirements, but the steel panel is impermeable. The characteristics of airtightness tend to make the appearance quality of the finished concrete poor; the rigidity of the conventional wooden formwork is poor, and it is easy to produce deformation and deviation when pouring large-volume concrete, and in serious cases, the formwork will burst and cause accidents
