Embodiment 1

[0026] Such as Figure 1-Figure 2 As shown, a reinforced structure of damaged wooden structure mortise and tenon joints, including wooden columns 2, beams 1, the end of the beam 1 is the tenon head part, using a group of horizontally parallel self-tapping screws 3, self-mortise The end of the part is drilled inward into the beam 1, and the set of horizontally parallel self-tapping screws 3 is located in the same elevation.

[0027] In this example, see figure 1 , the tenon is L-shaped and stepped, and its outer end protrudes from the wooden post 2 . The tenon part is through tenon.

[0028] In this example, see figure 1 , the length of the self-tapping screw 3 extending into the beam 1 is not less than 1 times the diameter of the wooden column.

[0029] In this embodiment, when the width of the tenon is not greater than 50mm, the diameter of the self-tapping screw 3 is 6-8mm; when the width of the tenon is greater than 50mm, the diameter of the self-tapping screw 3 is 8-10...

Embodiment 2

[0036] In this embodiment, the tenon is a dovetail tenon embedded in the wooden column 2, and a set of horizontally parallel self-tapping screws 3 start from the wooden column 2 and drill into the wooden column 2, the dovetail tenon and the wooden column 2 in sequence. Liang Fang1.

[0037] All the other are the same as embodiment one.

[0038] The invention provides a method for strengthening mortise and tenon joints of damaged wood structures, which can significantly improve the mechanical performance of mortise and tenon joints of damaged wood structures; and the method is simple and easy to implement, has little effect on the appearance of tenon and tenon joints, and is convenient for popularization .

Abstract

The invention relates to a reinforcing structure for a damaged wood structure mortise-tenon joint. The reinforcing structure for the damaged wood structure mortise-tenon joint comprises a wood pole and a tiebeam. The end of the tiebeam is a tenon portion. A group of transversely parallel self-tapping screws are inwards screwed into the tiebeam from the end of the tenon portion, and the group of transversely parallel self-tapping screws are located on the same facade. When the reinforcing structure for the damaged wood structure mortise-tenon joint is used for reinforcing, the facade structureof the wood structure is not damaged, the stage periphery structure is not influenced, and the force bearing capacity of the damaged wood structure mortise-tenon joint can be conveniently and effectively improved. The reinforcing method is easy to implement, has little influence on the appearance of the mortise-tenon joint and is convenient to popularize.

Description

technical field [0001] The invention relates to a reinforcement structure and a reinforcement method of a damaged wooden structure mortise and tenon joint, belonging to the technical field of civil engineering. Background technique [0002] Mortise and tenon joints are one of the commonly used forms of component connection in traditional wood structures. Since wood is a biomass material, long-term use will easily lead to cumulative damage such as dryness, decay, insects, aging, etc., and wood is a combustible material, so the probability of fire is high. For wooden structures in earthquake areas, they will also suffer from earthquakes. influences. Wooden structures need to be maintained and repaired before they can continue to be used after being damaged by cracks, rot, insects, aging, fire or earthquakes. The sections of the wooden beams and columns at the mortise and tenon joints are weakened, which is a weak position for the wooden frame. Therefore, the improvement of t...
