Abstract

PROBLEM TO BE SOLVED: To provide a tightening hardware capable of absorbing a machining error of tenon holes and bolt holes in the tightening of tenon forming of the columns and horizontal members and struts and horizontal members of a wooden building. SOLUTION: A loose hole 16 for drift pin or a female screw is provided in a long nut 2, and a gusset with screw is threaded with a hole with female screw through a spline tenon adjustably connected to the position of the hole with a bolt 4. A drift pin is inserted into the loose hole to accommodate the machining error so as to easily tighten the columns to the horizontal members.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mortise joint at a tenon connection between a pillar of a wooden building or the like, a horizontal member and a bundle and a horizontal member.

[0002]

2. Description of the Related Art The connection between pillars and horizontal members of a conventional wooden building is as follows.
It is a method that does not use nails or hardware, combining wood with complicated joint processing, which has been developed and inherited by the previous technician, and uses wood with sufficient cross section and strength for the members themselves, Joining is a method of fixing with a plug, a wedge, etc. to the mating and tenon of the mating, and requires advanced working techniques, and the precision of processing greatly affects the joining effect. Due to the deterioration of technical skills of engineers, pre-cutting has progressed, and the joint fitting construction method has been developed, and the "mortise" and the pipe tenon have become widespread.

[0003]

Conventional tying fittings such as mortise joints are pipe mortises provided with holes for tying. 1) Insert the pipe mortise into the mortise of the horizontal members and columns or bundles. When fixing with a drift pin or bolt for fastening, if a processing error occurs in the fastening hole between the horizontal member and the column or bundle, the drift pin or bolt cannot be loaded. 2) In order to handle the processing error in 1) above, a round hole for tightening the pipe tenon is made large. When a pull-out force is generated in the columns or bundles, a gap is created between the horizontal member and the columns or bundles and fixed. Degree decreases. 3) It is difficult to eliminate machining errors of drift pins and bolt holes for cutting a nose, a tenon, and fastening. 4) Construction and assembly takes time and skill. 5) Hardware such as washers cannot be attached to the pipe tenon. 6) Since the tenon of the pipe has a small cross-sectional area, if the tenon is threaded for joining or the like, the strength is significantly reduced. And the like.

[0004]

In order to solve the above-mentioned problems, in the present invention, a long nut 2 is provided with a drift pin or bolt hole 3 or a female screw 17. reference

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS When the mortise of the present invention is used, 1) When the mortise of the present invention is inserted into a tenon hole of a horizontal member and a column or a bundle and fixed with a drift pin or bolt for binding. , Even if there is a processing error in the connecting hole between the horizontal member and the column or bundle,
The long nuts can be adjusted with the connecting bolts by using the connecting bolts, so that the drift pins and bolts can be loaded. Furthermore, since the angle of the drift pins and bolt balls for binding the horizontal members to the columns and bundles is free, the construction performance is improved and the number of types of tenons is reduced. In addition, if the hole is a horizontally elongated hole, it becomes easier to insert drift pins and bolts for binding and the like, and the workability is further improved. Specifically, it can absorb machining errors such as the cutting of a single member, the mortise hole, the mortise hole, the drift pin and the bolt hole. 2 Because multiple long nuts can be joined with bolts,
Easily hire mortise, with holes for drift pins and bolts oriented at any angle. 3. Since the holes of multiple long nuts can be oriented at any angle, threaded gussets can be loaded for joining corners of a ridge or polygonal roof. 4. If a metal such as a washer is attached to the long nut with a bolt, it becomes a hold-in metal. 5. The method of inserting a hiring tenon into the mortise hole of the horizontal members and pillars and bundles and fixing it with drift pins or bolts for binding, so no reinforcing hardware such as locks is required.

[0006]

Embodiment 1 FIG. 5 shows a mortise 1 in which a long nut 2 provided with a hole 3 and a long nut are joined to each other with bolts 4 according to the present invention, and loaded into a tenon hole 5 of a base 8 and a pillar 7. Tighten the gusset 6 with a screw to the long nut 2 of the base 8, fix the large pull 9 and the pillar 7 on the left and right sides of the base 8, fix the washer 15 with the bolt 4, and make a holdown hardware. FIG. 6 is a vertical sectional view showing an embodiment 1. FIG. 6 shows a mortise 1 of the present invention, in which a long nut 2 joined by bolts 4 is loaded into a tenon hole 5 of a bundle 10 and a purlin 11 and a corner block 12 is attached. FIG. 4 is a vertical cross-sectional view in which a gusset 6 with a screw is used, and a washer 15 is attached to the long nut 2 with a bolt 4.

[0007]

The long nut provided with a hole according to the present invention is
When used in combination with bolts, the processing of columns and bundles and the connection of horizontal members can be done by cutting the lips, drilling, etc. If bolts are used to attach washers, they can also be used as holder hardware. The attached gusset can be attached at any angle, so you can attach a ridge or corner roof with a polygonal roof. still,
If the hole is made into a horizontally long hole, it becomes easier to insert drift pins and bolts for tightening, etc., further improving workability.
The same effect can be obtained by providing a hole or a female screw in a tan buckle or a pipe or a shape steel with a screw at the end instead of a long nut.
