Vertical semi-dovetail tenon node connection structure for wood structure building beam column

Abstract

The invention discloses a vertical semi-dovetail tenon node connection structure for a wood structure building beam column. In the wood structure building, the connection between a middle column and a wood beam or a side column and the wood beam adopts the vertical semi-dovetail tenon node connection structure, and knotting to each other is conducted through the tenon vertical semi-dovetail on the wood beam structure, so that the seismic horizontal bearing tensile strength of a frame is improved. Meanwhile, the vertical semi-dovetail tenon node has strong bending resistance ability. The vertical semi-dovetail tenon node is connected and applied to a wood structure farm house or a civil mixed structure, so that the seismic bearing ability of the wood structure farm house or the civil mixed structure is greatly improved; and the vertical semi-dovetail tenon node connection form makes a slight change on the basis of inheriting a traditional mortise and tenon node connection form, a nail and an iron are still not needed, the vertical semi-dovetail tenon node connection form is more suitable for drawing materials and constructing houses locally of remote mountainous areas, and the construction progress and construction quality are improved in a large degree; and meanwhile, cost of vertical semi-dovetail tenon node is low, and the cost of engineering structure can be reduced.

Description

technical field [0001] The invention belongs to the technical field of building structures, and relates to a wood structure building node connection structure, in particular to a vertical semi-dovetail joint connection structure used for wood structure building beams and columns. Background technique [0002] Mortise and tenon connection is one of the characteristics of traditional wooden structure buildings in my country. The connection between traditional wooden structure components is usually made of mortise and tenon connection without any iron or nail. Timber mortise and tenon is composed of mortise and mortise, which can withstand a certain bending moment, has good elasticity and resistance to horizontal thrust, shows strong semi-rigid properties, and allows certain deformation to absorb part of the earthquake energy , to reduce the seismic impact of the structure. [0003] A structure is composed of nodes and components. Among them, the joint is a more critical part...

AI Technical Summary

Problems solved by technology

Due to the traditional dovetail (horizontal dovetail) (see attached picture Figure 8-9 ) has a large weakening of the cross-section of the column; the beam is completely disconnected at the connection, the overall stiffness becomes smaller, and the integrity is weakened; Roof installation and connection, can not be installed and used in the middle of the height of the column, etc., the traditional through tenon (see attached picture Figure 6~7 ) has the disadvantages that there is no special pull-out design for the connection, and it is easy to pull out the tenon and fall off during an earthquake.
