Formwork and construction process for fabricating concavo-convex wood-grain fair-faced concrete wall

Abstract

The invention discloses a template and a construction process for making a concave-convex wood-grain fair-faced concrete wall. The template includes: an inner and outer double-layer template, wherein the inner layer is a rubbing board made of solid wood, and the outer layer is a base plate with a complete plane , characterized in that the rubbing board is fixed on the complete plane of the substrate, the rubbing board is formed by splicing wood boards of at least one thickness, and each thickness of wood boards includes several pieces. The construction process includes the following steps: (1) splicing several wooden boards on the base plate to form an inner and outer double-layer structure formwork; (2) setting several pieces of said formwork on the side of the wall that needs to form a concave-convex wood grain wall surface effect, and using One side of the rubbing board faces the wall; (3) pour fair-faced concrete and perform concrete curing for several days; (4) remove the formwork after curing and repair the defects on the wall.

Description

technical field [0001] The invention relates to a fair-faced concrete construction tool and a construction process, in particular to a formwork and a construction process for making a concave-convex wood grain clear-faced concrete wall. Background technique [0002] In ancient Rome, concrete was only a material for cementation on the masonry of traditional arches. It wasn't until the Pantheon built in 120 AD that concrete became an independent building material for building walls. In the twenties of the 20th century, more and more architects began to realize that the decorative features of clear-water concrete were used to express the emotion conveyed by the building. Le Corbusier's Marseille apartment, Louis Kahn's Yale University art gallery, etc. The first country in Asia is Japan, and Tadao Ando is the most representative. When clear water concrete is fully recognized and widely used in the world, Chinese people still focus on the selection of glass curtain walls and ...

AI Technical Summary

Problems solved by technology

[0005] The traditional formwork is difficult to meet the construction requirements, that is, it is difficult to meet the wall effect of forming a concave-convex wood grain structure on the wall after pouring. In the prior art, there is a technology that uses wood boards as the surface of the formwork, but what it achieves is the microstructure of wood grain. , on the large building wall, it is difficult to see the wood grain structure of the wall from a distance. It is necessary to realize the concave and convex wood grain structure of the wall of the large building that can be observed from a distance and a close view.
