wooden parts assembly

Abstract

The present invention provides a wooden component assembly that reduces the size of the fixing structure of the tension member arranged to improve the load-bearing performance of wooden components made of wooden materials, facilitates joining with other components, and improves the appearance . Screw a metal screw member (6) with a helically protruding wing (6a) on the outer peripheral surface of a cylindrical shaft portion (6b) having a through hole in the axial direction into a wooden member (1 ) in the two positions of the axial direction. There is a groove (3) or a hollow hole between the two screw parts, and the steel rod (2) is inserted from the through hole of one screw part (6) through the groove (3) or the hollow hole to the other screw part (6) in the through hole. In a state where tension is applied to the steel bar, both ends are locked to the screw member (6) via nuts (7). In addition, a cutting recess (4) is formed on both end surfaces of the wooden member, and the screw member is screwed into the cutting recess, and the steel rod is locked to the screw member in the cutting recess.

Description

technical field [0001] The present invention relates to a wooden component assembly, which has: a glulam formed by laminating small-section wood; a wooden component made of a wooden material such as natural wood; and a tension member arranged along the axial direction of the wooden component, Prestress is introduced into the above-mentioned wooden member by the tension force of the tension member. Background technique [0002] In a wooden building, a structure having a large space, such as a living room where many people can gather or a parking space where many cars can be parked, is sometimes required. In order to provide such a large space, it is necessary to install horizontal frame members such as beams between columns arranged at large intervals, and to support loads on the roof or upper floors. [0003] In order to support the load of the roof or the upper floor, wooden materials are sometimes reinforced with steel materials or the like in horizontal frame materials e...

AI Technical Summary

Problems solved by technology

In order to prevent such deformation, it is necessary to enlarge the contact area of ​​the metal parts and to enlarge the structure for fixing tension members such as reinforcing steel rods.

In addition, the structure for fixing the tension member is exposed from the side of the wood, or hinders the joining of the end of the wood to other members.
