Cross-laminated timber wall dovetail tenon connecting technology and manufacturing method

Abstract

The invention relates to a cross-laminated timber wall dovetail tenon connecting technology and a manufacturing method and belongs to the technical field of timber engineering. A cross-laminated timber wall dovetail tenon connecting structure comprises a dovetail tenon wall and a dovetail mortise wall. A dovetail tenon of the dovetail tenon wall is processed in the end face of cross-laminated timber in the longitudinal direction of the wall, a dovetail mortise of the dovetail mortise wall is milled in the plane of the cross-laminated timber in the longitudinal direction of the wall, and the dovetail tenon and the dovetail mortise are in angle fit to be processed. When a building of a timber structure is constructed, the dovetail tenon wall and the dovetail mortise wall are aligned to be driven in a hoisted mode, and accordingly connection is completed. The cross-laminated timber wall dovetail tenon connecting technology is mainly applied to connecting of the building walls of the cross-laminated timber structure, a mortise and tenon structure in an ancient building in China and a modern timer structure are combined, the strength requirement of a wall connecting joint can be met, factory prefabrication can be achieved, and rapid site construction can be achieved.

Description

Technical field: [0001] The present invention relates to a cross-glued wood wall dovetail connection technology and a manufacturing method, specifically, a technology for connecting two cross-glued wood walls using a dovetail structure, and self-tapping screws or The adhesive reinforces the joint and belongs to the technical field of wood engineering. technical background: [0002] Cross-Laminated Timber (CLT for short) is a new type of engineered wood material made of standard timber criss-cross pavement. Cross-laminated timber has superior mechanical properties and stable in-plane performance. It can be used as the main building material to build medium and high-rise wooden structures, and it can also replace prefabricated concrete panels in general buildings. In recent years, medium and high-rise wood structure buildings have risen rapidly all over the world. The "Code for Design of Multi-Story Wooden Structures" promulgated by my country in 2017 has allowed the constru...

Problems solved by technology

Foreign researchers have found that the traditional connection methods applied to CLT, including angle steel connection, anchor connection and self-tapping screw connection, cannot give full play to the superior performance of CLT.
