Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a fastener for a long horizontal member, and more particularly to improvement of a driving wedge portion.

[Conventional technology]

The applicant filed a Japanese application No. 63-15 filed on November 28, 1988.
No. 4444 has filed an application for the fastener a shown in FIGS. That is, the fastener a is provided integrally with the substrate 31 and the mounting plate formed in an L-shape on two edges of the rectangular plate 32, and the strip 32 is formed with the ridge 39 in the vertical direction. It was done. The column 33 and the long transverse member 42 are members fastened by the fastening members a. That is, the mounting surface 40 of the column 33 is provided with a shallow mounting hole 41, and one end of the horizontal member 42 is abutted against the mounting hole 41.

On the other hand, a longitudinal burying hole 43 is cut at an end of the horizontal member 42, and a hole 391 corresponding to the ridge 39 is formed therein. The end face 421 has a fastening bolt 3 described later.
A nut hole 371 for receiving the nut 37 screwed into 5 is formed, and a wedge 38 is driven between the ridge 39 and the hole 391. Reference numeral 44 denotes an upper fixing plate which is fastened by a bolt 45 to a screw hole 46 provided on the upper surface of the fastening member a, and clamps an end of the horizontal member 42 with the fastening member a.

Since the fastening structure of the horizontal member configured as described above has a large number of engaging portions such as the buried hole 43, the hole 391 and the nut hole 371 at the end, the fastening portion becomes complicated and the productivity is increased. At the same time, it was difficult to maintain, and at the same time, there was a problem that the ends were weakened. Also, in the case of a large diameter of the horizontal member, the wedge 38 is inevitably large, and the driving work is not easy.

Therefore, it is considered that the wedge hole on the side of the fastener is slightly shifted from the side hole on the side of the long transverse member toward the column, and a wedge made of a metal bar is inserted into the wedge hole and locked. (Eg, Japanese Utility Model Publication No. 57-24805).

[Problems to be solved by the invention]

However, conventionally, in order to obtain a wedge having relatively large strength, a metal round bar has been used. Therefore, when using a plurality of such wedges, if the amount of “shift” in each wedge hole is not constant, an excessive fastening load may be applied to some of the wedges or fasteners to damage them. Was.

[Means for solving the problem]

The purpose of the present invention is to solve the above-mentioned disadvantages. The first invention is to provide a plate-like body standing on a substrate and to provide a fastener having a mounting plate connected to a pillar at one end thereof. While connecting the fastening fitting to the pillar, an embedded hole for vertically inserting the fastening fitting is provided at an end of a long horizontal member connected to the pillar,
A plurality of wedge holes and side holes are provided for the wedge for penetrating the fastener and the elongated cross member horizontally in the horizontal direction to connect them, and the wedge hole on the fastener side is connected to the elongated cross member. The wedges are tapered from the one end in the longitudinal direction to the other end, and are tapered into the plurality of wedge holes.

In the second invention, a wedge receiving plate is attached to the opposite side of the wedge hole column of the fastener, and wedges driven into the plurality of wedge holes are divided diagonally so that each end becomes thinner. The third invention is to provide a fastener formed by erecting a plate-like body on an elongated substrate, and to vertically attach the fastener to the ends of both long horizontal members to be connected. A plurality of wedge holes and horizontal holes are provided for the wedges that penetrate the fasteners and the two horizontal members in the horizontal direction and connect the two, and a buried hole is provided in the fasteners side. The wedge holes are provided slightly shifted from the end of the long transverse member with respect to the transverse holes on both long transverse member sides, and the plate thickness changes from one end in the longitudinal direction to the other end. Is inserted into the wedge hole.

In the fourth invention, a wedge receiving plate is attached to a side opposite to the end surface of the long transverse member of the wedge hole, and wedges driven into the plurality of wedge holes are diagonally divided so that each tip becomes thin. Two wedges.

[Action]

When the hole for embedding the horizontal member in the fastener attached to the column is fitted, the height and direction of the plurality of wedge holes provided in the fastener and the horizontal hole provided in the horizontal member substantially match, and the fastening metal Since the wedge hole provided in the horizontal frame is located at a position shifted from the horizontal hole provided in the horizontal material or to the column side, if the wedge is driven between the two holes, the horizontal material is pressed against the column side, and the There is no gap between the end face and the pillar. In addition, even if the relationship between the wedge hole and the horizontal hole is shifted from one hole to another at the festival, the so-called tapered wedge is used because the tip of each wedge is narrow, By changing the length, the load applied to each wedge can be adjusted.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, as shown in FIG.
A rectangular plate 2 is erected at the center in the upper longitudinal direction. A mounting plate 3 is provided by bending one end of the substrate 1 upward at a right angle. The plate 2 is welded to the substrate 1 and the mounting plate 3 to be integrated. A bolt hole 6 is formed on both sides of the mounting plate 3 for passing a connecting bolt 5 penetrating the column 4. 7 is a nut.

A mounting hole 9 for inserting the mounting plate 3 into the mounting surface 8 of the pillar 4 is formed. A long horizontal member 10 connected to the column 4 is provided with a buried hole 11 for inserting the above-mentioned fastening member A in a vertical direction. A nut hole 71 for receiving the nut 7 of the fastening bolt 5 is formed in an end face 101 of the horizontal member 10 which contacts the column 4. The pillar 4 may be made of wood or metal.

A screw hole 14 for a fixing bolt 13 for fixing the upper fixing plate 12 is formed on the upper surface of the plate 2. A stud may be provided upright instead of the screw hole.

A wedge 15 is driven in the left-right direction to connect the fastening fitting A and the long horizontal member 10. For this reason, the plate-like body 2 of the fastening fitting A
A plurality (three in the figure) of wedge holes 16 are provided in the horizontal direction at intervals in the vertical direction. In the embodiment, the openings are provided in one row. However, when the fastening fitting A is large, two or more rows may be provided. As is clear from FIGS. 1 to 3, the wedge 15 is formed in a so-called tapered shape in which the plate thickness changes from one end in the longitudinal direction to the other end. A space is made slightly shorter than the width of the long horizontal member 10 to insert the burying trees 18 and 18 at both ends.

On the long horizontal member 10 side, a horizontal hole corresponding to the wedge hole 16
17 and 17 are provided on both sides of the buried hole 11. In this case, the wedge hole
As shown in FIGS. 2 and 3, the 16 is shifted slightly toward the pillar 4 side, specifically 3 to 5 mm, with respect to the horizontal holes 17 and 17.

The wedge hole 16 to be opened to the fastening bracket A is a horizontal hole of the long transverse member 10.
17 and 17, slightly shifted to the pillar 4 side, wedge 15
At the same time, the long transverse member 10 and the fastening fitting A are connected, and at the same time, the long transverse member 10 moves to the column 4 side, and both are pressed together without a gap. Since the wedges used in the festival are formed in a tapered shape, the load acting on each wedge can be equally distributed by changing the depth of the wedges.

4 and 5 show a second embodiment. In the figure, fastening bracket A
To the opposite side of the pillar 4 in the wedge hole 16 Receiving plate 19 of the wedge hole 15
Is attached. Further, the wedge 15 is diagonally divided into two wedges 151 and 152 so that each end becomes thin. The same applies to the case where the wedge holes 16 are offset from the horizontal holes 17.

As described above, since the two wedges 15 are used for driving from both sides, the driving is easy. In addition, since the receiving plate 19 is attached to the opposite side of the column 4, the step between the wedge hole 16 and the horizontal hole 17 turns to the wedge 15
Since it does not appear on the side, the wedge 151 is easy to drive. Further, since the wedges 151 and 152 receive the force on a wide surface, there is no possibility that the wedges 151 and 152 are broken even when a large force is applied.

FIG. 6 shows a third embodiment in which two long transverse members are connected in a straight line. An elongated substrate 21 as shown in FIG.
A plate-like body 22 having the same length as 21 is erected, and both are welded to be integrated.

In the long horizontal members 23, 23 to be connected, burial holes 24, 24 for vertically inserting the above-mentioned fastener B are formed. A wedge 25 is driven in the horizontal direction as a connection between the fastening fitting B and the two long transverse members 23. For this reason, three horizontal wedge holes 26 are provided on the left and right sides of the plate-shaped body 22 of the fastener B at intervals in the vertical direction. When the fastening fittings B are large, two or more rows are provided and the number of holes is increased.

The long horizontal members 23, 23 also correspond to the wedge holes 26,
Drill lateral holes 27, 27 on both sides of the buried hole 24.

In this case, the wedge holes 26 are slightly shifted from the lateral holes 27, 27 toward the end surface 23a of the long transverse members 23, 23. This is the same as in the first and second embodiments. The upper fixing plate 28 is fixed to the upper end of the fastener B by the fixing bolt 29.

The other points are the same as those of the first embodiment, and the description is omitted.

Also, in the third embodiment, similarly to the second embodiment, a wedge receiving plate (not shown) is attached to the side opposite to the end surface 23a of the long transverse member 23 of the wedge hole 26 of the fastening member B, It goes without saying that the fourth embodiment in which two wedges are used to drive in from both front and rear sides can be performed.

[Effect of the invention]

According to the present invention, (1) By driving a wedge into a fastener provided on a horizontal member, the horizontal member is pressed against the column, and the end face of the horizontal member and the column are in close contact with each other. Further, since the wedge is driven from the horizontal direction instead of the means for driving from above, the wedge is shorter and easier to drive than the conventional wedge.

(2) For the same reason, the fastener has no ridges, so that the fastener is simplified.

(3) Since each wedge is tapered, even when the gap between the wedge hole and the transverse member is not constant, the load applied to each wedge can be made uniform by adjusting the driving depth. can do.

(4) In the second invention and the fourth invention, since the wedge receiving plate is attached to the fastener, the wedge is easy to be driven, and the wedge is received on the surface of the receiving plate. There is no fear of breaking.

In addition, since the two fins having thinner tips are driven from both front and rear sides, they are easy to drive and can be driven to the full.

And so on.
