Description

[Detailed Description of the Invention] The present invention relates to a fastening member for an L-shaped frame fitting in a wooden building.

Traditionally, L-shaped frame fittings in wooden buildings have been used to connect columns and horizontal members such as beams and girders, and to reinforce them or attach braces. A bolt is inserted through a hole in each bent piece, penetrates from the side of the wood that is in contact with the metal fittings to the opposite side, and is tightened with a nut.

However, when attaching to a horizontal member (lower beam) and a column that have already been installed on foundation concrete, it is not possible to insert bolts and tighten them.

The present inventor has discovered that when installing an L-shaped frame fitting, the frame can be assembled without passing a bolt through the surface of the metal fitting from the abutting surface of the wood to be joined to the opposite surface. As a result of research on the tightening of L-shaped frame fittings, the present invention was a distant relative.

In the present invention, a lower end that can be inserted into the recumbent material and inserted into the through hole 4 that abuts the recumbent material side of the L-shaped frame fitting 1 that frames the corner of the recumbent material 10 and the pillar 11, is provided. A method for fastening frame fittings in a wooden construction, characterized in that a screwable connecting member 7 having a plate 9 having a through hole 8 for insertion of a bolt 6 and a supporting hole 8 that can be penetrated from both sides of a lying material is fastened. This relates to a connecting member for use.

Next, an example of implementation of the present invention will be explained with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the state in which the present invention is used, and FIG. 2 is a front view showing an embodiment of the connecting member of the present invention.

In the figure, reference numeral 1 denotes an L-shaped ring fitting, which is generally bent at an angle of 90°.

Reference numeral 2 denotes reinforcing parts stretched on the vertical and horizontal edges of the L-shaped frame fitting 1.
When the brace 5 is arranged on the wall, the brace 5 is attached to the wall surface or the like with or without contact.

Reference numerals 3 and 4 indicate through holes provided in the bent surface of the above-mentioned L-shaped frame member, and although they are provided in one example in the illustrated example, they may be provided in one row or three rows.

Reference numeral 6 denotes a bolt having a hole I, which is used as the connecting member 7 of the present invention when the L-shaped frame fitting 1 is fastened to the side member 10 side.
When the L-shaped frame member 1 is fastened to the pillar 11 side, it is inserted through the through hole 3 of the frame member 1.

Reference numeral 7 denotes a connecting member of the present invention which connects the above-mentioned L-shaped frame fitting 1 and the bolt 6 as necessary, and a nut is screwed into its upper end, and the bolt 6 is inserted through its lower end. A plate 9 having a through hole 8 is integrally provided.

Next, how to use the present invention will be explained.

L-shaped frame fittings 1 are arranged on the corner surfaces of the rectangular beams of the horizontal beams 10 and the pillars 11 erected thereon on the foundation concrete of a wooden building, and the horizontal beams 10 in which the through holes 4 are located. A vertical hole is drilled in a predetermined portion of the plate 9 of the connecting member 7, and the plate 9 of the connecting member
is inserted so that it is perpendicular to the longitudinal line of the lying member 10.

In this case, the center of the through hole 8 provided in the center of the plate 9 should be located below the longitudinal center line of the lying material 10, preferably at a position approximately 415 below the width of the iron material from the upper edge. .

Next, a through hole is drilled directly below the through hole 4 and at a position 415 below the upper edge, that is, from both sides of the lying member 10 at a portion corresponding to the through hole 8 position of the plate body 9, passing through the through hole 8. After inserting the bolt 6 into this through hole and the through hole 8 of the plate body 9 and tightening both ends with nuts, the spiral protruding upward from the through hole 4 of the L-shaped frame fitting 1 is inserted. Tie one end with a nut.

Further, on the column 11 side, a through hole is bored from its outer surface to a predetermined part of the through hole 3 of the L-shaped frame fitting 1, and a bolt 6 is inserted into this and both ends are tightened with nuts. It is something.

In addition, in the case of the L-shaped frame member 1 provided with the reinforcing portion 2, it is further tightened with a brace member 5 provided with a turnbuckle.

According to the present invention, since it has the above-mentioned configuration, the so-called
When assembling the corner of the horizontal member 10 and the pillar 11 with the L-shaped frame member 1, a through hole 4 is provided which comes into contact with the horizontally collapsed side of the frame member 1.
In particular, a screwable connecting member 7, which can be inserted into the recumbent material and has a plate 9 at its lower end that has a through hole 8 for insertion of bolts 6 and for support, which can be penetrated from both sides of the recumbent member, is fastened. In this way, the horizontal member, the L-shaped frame fitting, and furthermore the pillar are strongly assembled, so the bolt insertion holes are inserted into the horizontal member 10.
In other words, the hole into which the connecting member 7 of the present invention is inserted is drilled at a depth of approximately 315 to 415 mm from the top surface of the horizontal piece, and the bolts pass through both sides of the horizontal piece. This method is extremely effective, strong, and easy to assemble when it is not possible to provide through holes on the top and bottom, such as in square timbers lying on foundation concrete. It is something that can be done.
