Embodiment

[0022] Take two square wooden columns made of Douglas fir, both with a side length of 200mm and a height of 650mm. One as an unreinforced comparison specimen;

[0023] The other is reinforced and repaired with the patented solution of the present invention: the angle steel is an equilateral angle steel with a specification of 50mm×3mm, the length, height and thickness of the steel panels are 200mm, 50mm and 3mm respectively, and the distance along the height direction is 400mm.

[0024] as attached figure 1 and 2 Shown, the concrete steps that carry out reinforcement by the present invention are:

[0025] (1) Treatment of wooden column 1: chamfer the four column corners along the full height of the column body, and carry out flatness treatment on wooden column 1, and the flatness is 0-1.5mm; the chamfering radius of wooden column 1 is the same as that of the selected angle steel 2 Corresponding to the inner angle, the error is not greater than ± 2mm.

[0026] (2) Paste ang...

Abstract

A method for reinforcing a rectangular wood column by pasting angle steel comprises the steps of wood column processing, angle steel pasting and steel batten plate welding. The angle steel is pasted to the angle portion of the wood column, a steel batten plate is welded in the height direction, the bearing force and the ductility of the wood column can be effectively improved, and meanwhile the requirements for reinforcing and repairing for corrosion resisting and durability are met.

Description

technical field [0001] The invention belongs to the field of building science and technology, and specifically relates to a method for pasting angle steel to reinforce a rectangular wooden column, which is used for maintenance, reinforcement and transformation of wooden structures. Background technique [0002] The use of wood to build houses is an important form of construction in my country. After years of use in wooden structures, wooden columns often suffer from cumulative damage such as splitting, rotten grooves, and aging. Traditionally, the inlay method or the inlay and hoop method are often used to solve the splitting of the wooden structure; according to the degree of decay of the wooden structure, different repair and reinforcement methods such as palm tenon, chasing tenon, mantis tenon and pier are used to solve the problem. In the case of rotten troughs, once the troughs of the wooden structure are rotten to the point where they cannot bear the load, the wooden c...
