Dot-matrix cross-grain reinforced wood structure mortise and tenon joints

Abstract

The invention discloses a dot-matrix type horizontal grain enhanced wood structure mortise-tenon joint which comprises a wood column, a wood beam and a dot-matrix type high-strength material used for tenon enhancement. The wood column and the wood beam are connected in a mortise-tenon joint mode, a tenon is provided with a hole in the height direction of the wood beam, the hole penetrates through the tenon in the height direction of the wood beam, the diameter of the hole is 0.5-2.0 mm smaller than that of the dot-matrix type high-strength material used for tenon enhancement, the dot-matrix type high-strength material used for tenon enhancement is inserted into the hole, the surface of the dot-matrix type high-strength material used for tenon enhancement is smooth or provided with a threaded structure in advance, the high-strength direction of the dot-matrix type high-strength material used for tenon enhancement and the height direction of the wood beam are consistent, the dot-matrix type high-strength material used for tenon enhancement is made of wood or bamboo, and the surface of the dot-matrix type high-strength material used for tenon enhancement is coated with an adhesive agent. The dot-matrix type horizontal grain enhanced wood structure mortise-tenon joint is mainly used for mortise-tenon joint reinforcement and enhancement of traditional wood structure buildings.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to a dot-matrix horizontal grain reinforced wood structure mortise and tenon joint. Background technique [0002] my country's wooden structure buildings have a long history and are distributed all over the country. Wood structure buildings account for more than 50% of all ancient buildings. Its excellent techniques have extremely high historical, cultural relics, artistic and scientific values. The most notable feature of the traditional wooden structure is that the frame composed of columns and beams adopts the connection form of mortise and tenon. As early as 7,000 years ago, a large number of tenon and tenon joints of wooden structures were found in the Hemudu site. Subsequent wooden components of ancient Chinese wooden buildings Mortise and tenon joints are commonly used. Mortise and tenon means that according to the needs of the connection of the compon...

Problems solved by technology

[0010] Most of these reinforcement methods have the following disadvantages: the nails, flat steel, curved steel plates, metal gusset plates, and carbon fibers used in the reinforcement of the joints are all exposed, and the appearance of the reinforced joints is low in aesthetics, which is harmonious and unified with the appearance of wooden materials Poor performance, losing the beauty of the wooden structure itself; the use of metal connectors requires additional anti-rust treatment and post-use and maintenance measures, and the process is cumbersome
