Ancient building wooden pillar reinforcing, fire-prevention and decoration integrated construction method

Abstract

The invention discloses an ancient building wooden pillar reinforcing, fire-prevention and decoration integrated construction method. The method includes the following steps that, 1, the surface of an ancient building wooden pillar is cleaned and polished; 2, carbon fiber cloth is pasted to the surface of the wooden pillar by means of a carbon fiber cloth adhesive; 3, fireproof fiber cloth is pasted to the outside of the carbon fiber cloth by means of fireproof glue; 4, decoration construction is conducted on the surface of the fireproof fiber cloth. Compared with decorating techniques using putty and plasters, the method is simple in technological operation step, has no special requirements of raw materials, and is low in production cost and suitable for low-cost rapid repair of the ancient building wooden pillar.

Description

technical field [0001] The invention belongs to the technical field of protection of wooden pillars of ancient buildings, in particular to an integrated construction method for reinforcing fireproof decoration of wooden pillars of ancient buildings. Background technique [0002] Due to the long-term loading time or wind and snow erosion of the wooden structure of ancient buildings, the performance of the material has deteriorated, so it is necessary to strengthen the wooden structure. Due to the limited resources of wood, it is impossible to replace new materials in a large area during the restoration and reconstruction of wooden structures. This is especially true for rare materials and cultural relics. [0003] The reinforcement of wooden structures is mainly reflected in the reinforcement of components and joints. Common reinforcement methods include setting diagonal braces, caulking and hooping, chemical grouting, and sticking steel plates. However, these traditional met...

AI Technical Summary

Problems solved by technology

For example, although the reinforcement by sticking steel plates can improve the strength and rigidity of the components, the steel plates have the disadvantages of being heavy, easy to corrode, and difficult to shape, and cannot be widely used in the reinforcement of wood structures.

Wood itself is a combustible material. A considerable part of ancient buildings use wooden structures, which also have high requirements for fire protection of wooden structures. Although the method has a certain fireproof effect, it does not greatly improve the fire resistance time of wooden structures, and there is still a high risk

[0004] The traditional wooden structure decoration process is putty floor covering. This kind of finishing process is complicated to operate, has high requirements on raw materials, and high production cost, which is not suitable for today's development trend.
