A method for compositely strengthening wooden beams

Abstract

The invention belongs to the field of civil engineering and discloses a method for compound reinforcement of a wooden beam. The method is characterized in that at the bottom of the wooden beam (1), fiber cloth (3) is adhered, a base layer (5) is arranged, a bamboo board (2) is adhered and a round bolt (6) is screwed to achieve compound reinforcement of the wooden beam (1). In the method, the bamboo board (2) is used as a reinforcing material, meanwhile the fiber cloth (3) is mechanically anchored, the bonding effect of the bamboo board (2), the fiber cloth (3) and the wooden beam (1) is strengthened through fusion of the round bolt (6) with the bamboo board (2) and the wooden beam (1), and the thickness of epoxy resin glue (4) between the bamboo board (2) and the wooden beam (1) is ensured by arranging the base layer (5) embedded with a solid filling (51). By the adoption of the method, the probability of untimely damage due to bonding layer failure in the wooden beam bending process is reduced, the wooden beam is reinforced by adopting two low-carbon environmentally friendly materials, respective advantages of the two materials are fully played, the bearing capability of the wooden beam is improved, and an original style and features of an old historic building structure restored as the old are achieved.

Description

technical field [0001] The invention relates to a method for compositely reinforcing wooden beams, which belongs to the field of civil engineering reinforcement. Background technique [0002] The development of wooden structures in ancient buildings in my country has a long history, which can be traced back to 3,500 years ago. The emergence, development, and changes of wooden structures run through the entire development process of ancient buildings, and they are also one of the most important architectural forms of ancient buildings in my country. The research and application of modern wooden structures is also relatively extensive. Its superior seismic performance and high strength-to-weight ratio make it a typical ecological and environmentally friendly structural form. Wooden structures often face market demand for reinforcement during long-term use, especially for wooden beams, which are important stress-bearing components of wooden structures, and their bearing capacit...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for compositely reinforcing wooden beams, improve the bearing capacity of wooden beams, and solve the deficiencies in the existing reinforcement technology of wooden beams, such as solving the problems of easy bonding and damage of fibers in the pasting fiber reinforcement method and the steel plate of the bonding steel reinforcement method. It is easy to rust and other technical problems, and realizes the original style of the old wooden structure of ancient buildings. It can be used for the reinforcement of various wooden structure beams
