Abstract

<P>PROBLEM TO BE SOLVED: To provide joining hardware capable of tightening a joining part of framework without causing play and rickety motion in a joining method for the wooden framework. <P>SOLUTION: A bolt having a hexagonal head using a lag screw as a shaft and creating length of 30 to 40 mm of a mm bolt at a tip in one body, heavy gage shaped steel, and unequal angle steel are cut to bolt washer width, and bolt holes are drilled in two portions or three portions in accordance with required strength to provide a washer for converting bolt stress by 90°. When strength is required, combination of two washers is used as a T-steel of three hole type or five hole type. When it is necessary to mount the washer on a lag screw shaft, a lag screw nut is manufactured, the nut is locked, and fitting is attached. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Detailed Description of the Invention

The conventional wooden frame has been improved in various ways, but it is still devised as a part of the improvement for this, which is not yet completely compatible with drying and moisture absorption. In order to keep the play of the bolt to a minimum, the rugged screw spiral of 4-5 mm thicker than the diameter of the male spiral part is made to correspond to the change in thickness using the bolt shaft, and the bolt head is a hexagonal head as before, Using a bolt made of 30 mm to 40 mm long at the tip, and connecting the stress to the L shape, the unequal side L-shaped steel is cut according to the required washer width and penetrated. Necessary drilling of bolts at 2 or 3 locations. When further strength is required, use the same type of unequal side L-shaped steel as a T-shape steel with 3 or 5 locations. Use a rag screw spiral bolt or mm screw rag screw spiral bolt.

FIG.

For the joints of large ants and scythes that have been widely used in the past, follow-up large plug joints, follow-up lug screw joints, or follow-up wood screw joints are frequently used.

The same applies to the through pillars. If the cross section is insufficient using 105 corners and 120 corners, the drawing is presented as one I-shaped or two L-shaped.

FIG.

Reinforce the composite column using the bolts. This is because the wall thickness is not changed, the dimensional change of the interior, exterior, fittings, and the like is reduced, and general off-the-shelf products are used without difficulty.

Even if it is attached to the T-shaped joint of a horizontal member, it will be a short mortise rugged screw stop, and a wing head bolt and dovetail head will not be used as a rugged screw stop for the column head beam joint.

The hardware that penetrates the inner wall side from the outer surface of the outer wall of the structural material such as foundation, trunk difference, girders, beams, pillars, etc. facing outwards must be carved and the hardware protrudes from the outer surface of the structural material. First, install a ventilation column with a moisture-permeable sheet, so that the surface of the hardware is not directly shaken by the outside air. This is to prevent condensation and frost due to indoor penetration.

The T-joint is also a short tenon lag screw screw-in stop, and the length under the neck is increased by the required strength for large beams, pillars, and joints, and two or more are used.

In the conventional bolt tightening method, when the hole is drilled, the front hole is made 3 to 5 mm larger than the diameter of the male spiral part, and recently, the shaft diameter of the bolt is 1 than the diameter of the male spiral part. A thin product of ~ 2mm is used. For this reason, play was generated in less than half a year even when the screw was tightened.

A hexagonal head bolt with a 30mm to 40mm long bolt at the tip centered on a rag screw.
A washer that cuts heavy shape steel and unequal side angle steel into bolt washer widths and drills two bolt holes or three bolt holes according to the required strength to convert bolt stress by 90 °.
When further strength is required, two pieces are combined and used as a three-hole or five-hole type T-shaped steel.
When it is necessary to attach the washer to the rag screw shaft, manufacture the rag screw nut, and stop the nut and attach the bracket.

Inside the wall, the base, the pillar, the main line, or the column, the main line, the torso, the pillar, the main line, etc. Without tightening, complete the tightening.

FIG.

When fastening, use a woodworking drill to drill a fine tip hole and use an impact wrench to tighten bolts and nuts. There is no need to force a large diameter bolt.
