Connection hardware for wooden building

Abstract

A connection hardware for a wooden building which is contributive to efficient construction of a large wooden building, can save the space when it is transported, and can draw a lateral member toward a longitudinal member when they are jointed. The connection hardware for a wooden building comprises a basic hardware (3) secured to the side face of the longitudinal member (1), and an accessory hardware (4) coupled into a containing groove (U) provided in the end face of the lateral member (2) by means of a fixing metal on the rear surface of the containing groove (U). An upper receiving portion (12) having a longitudinal hole (10a) where its inner surface on the projecting side is an inclining surface (11c) is provided at the upper portion of the accessory hardware (4) and a downward tapered portion (9) is provided at the lower portion. On the other hand, an upward tapered portion (6) which can be inserted into the longitudinal hole (10a) of the upper receiving portion (12) is provided at the upper portion of the basic hardware (3), and a lower receiving portion (13) having a longitudinal hole (10b) capable of receiving the downward tapered portion (9) and forming, on its inner surface on the projecting side, an inclining surface (11b) is provided at a lower portion.

Description

technical field [0001] The present invention relates to a connecting metal fitting for timber construction that connects longitudinal members (columns, beams, trusses, etc.) and cross members (beams, trusses, etc.). Background technique [0002] In recent years, reflecting the trend of emphasizing the comfort of users, for example, the wooden structure of large buildings such as school buildings has been continuously developed. Metal parts of wooden buildings. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 8-120791 [0004] In the case of a large wooden structure building, the number of parts required is significantly larger than that of a single-family house, and in the case of construction of a large object, it is almost always determined by the customer with a strict deadline. However, such a conventional connecting metal member requires a lot of work on site in order to ensure sufficient connection strength between parts, and there is a possibil...

AI Technical Summary

Problems solved by technology

However, since the longitudinal member and the transverse member in the state where the connecting metal fittings are attached have a long protruding length from the wood, when stowed on a car or the like, the protruding length of the stowage space is wasted, resulting in a waste of storage space. As the loading capacity decreases, there may be a cost increase caused by deterioration in the efficiency of material transportation and a significant delay in the construction completion delivery period
