Connection structure of wood frame column in multi-story and tall wood structure

Abstract

The invention discloses a connection structure of a wood frame column in a multi-story and tall wood structure. The connection structure comprises a wood column, prefabricated grooves, embedded type steel connection pieces, bolt holes and bolts, wherein the wood column is divided into an upper column and a lower column, and connection nodes of the upper column and the lower column are positioned at positions which are as high as the half storeys of adjacent upper and lower layers; the prefabricated grooves with identical sizes and depths are formed in two splicing sections of the upper column and the lower column; the embedded type steel connection pieces are mounted in the prefabricated grooves; the bolt holes are formed in the outer walls of the prefabricated grooves and the embedded type steel connection pieces; the bolts penetrate through the bolt holes and are tightened, so that the upper column and the lower column are connected to form the entire long wood column. According to the connection structure, short columns are used as the wood column connection nodes at the positions which are as high as the half storeys of the adjacent layers and then are spliced to reach a required height, but the intensity and the whole performance of the wood column cannot be reduced by splicing; therefore, the wood column can be either produced and spliced in a factory or spliced on the site. The connection structure improves the construction efficiency, is high in feasibility and can be well applied to actual engineering.

Description

technical field [0001] The invention relates to a novel structure of construction engineering, in particular to a connection structure of frame column nodes of a multi-story wooden structure. Background technique [0002] At present, most of the wooden structure buildings are low-rise buildings with 2-3 floors. With the increase of population, the gradual reduction of construction land and the expansion of the application range of wooden structures, multi-high-rise wooden structure buildings have gradually become a development hotspot. Compared with the traditional structural form, the multi-story wooden structure building can adopt the construction method of prefabricating the components of each part in the factory and assembling on site, which can complete the construction and installation of the house more quickly, efficiently and conveniently. It is very important and necessary that the completed wooden structure building has the excellent performance of being green, com...

Problems solved by technology

[0003] At present, there are few studies on the disconnection position and node connection of wooden frame columns in multi-story wooden structures. The existing frame node forms are cumbersome to make, and the connection positions of wooden columns are mostly at the foot of the column, where multiple member nodes are connected. A converging bolt group is formed, and the bending moment at the foot of the column is the largest. As a connection point here, it is not conducive to the lateral performance of the joint under horizontal load. low efficiency
