Description

[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building metal fitting, and more particularly to a metal fitting used to fix an end portion of a bracing of a wooden construction to an inner corner of a frame.

[Prior art]

In a wooden building, a rectangular framework is formed by beams and columns,
Using braces to reinforce the framework. As shown in FIGS. 4 and 5, a conventional bracing method is to prepare a bracing 2 having a length corresponding to the diagonal length of the frame 1 formed by the beams 6, 7 and columns 8. , Both ends thereof are cut into a sword-like shape, the tips 2a, 2a thereof are fitted to the inside corners 3, 3 of the frame, the nails 4 are hammered in obliquely, and then the reinforcing plate 5 is attached to the side face to form the frame 1 And the braces 2 were fixed.

[Problems to be solved by the device]

In order to fit the braces in the frame without any gaps, it is necessary to cut the braces to the correct length, but in reality, it is not uncommon for some braces to be created, and as a result, sufficient bracing action as braces is achieved. There is a problem that it is not demonstrated. Furthermore, even if the braces are fitted tightly into the frame during construction, the braces may dry and shrink, creating a gap between their tips and the inner corners of the frame. Can't give. The present invention reduces the number of steps required to cut the braces to an accurate length, and allows the braces to be attached to the frame without gaps by simple operation, thus providing sufficient strength to the frame. The purpose is to provide bracing fixtures that can be used.

[Means for Solving the Problems]

The bracing fixture 23 according to the present invention comprises two mutually orthogonal seating surfaces 11a, 11b attached to the inner corner 3 of the building frame 1 formed by the beams 6, 7 and columns 8. L-shaped seat 11
And the support shaft 15 in the direction parallel to the seat surfaces 11a and 11b of the L-shaped seat.
And a support member 16 that is pivotally supported by and extends in a direction that bisects the included angle of the L-shaped seat. The support member 16 has a receiving portion 17 into which the end of the brace 2 is inserted at the tip.
The receiving part 17 is provided with a bottom plate 19 for receiving the cut end face of the inserted braces 2 in the direction perpendicular to the longitudinal direction, and the bottom plate 19 is provided with the screw rod 20 and the nut member 21 in the extending direction of the support member 16. It is movable back and forth in the extending direction of the support member 16.

[Action]

The L-shaped seat 11 of the fixing bracket 23 is attached and fixed to the lower inner corner 3 of the rectangular frame 1 formed of beams and columns, and the base end of the braces 2 is attached to the receiving portion 17 at the tip of the supporting member. Insert the screw rod 20
When it is advanced to, the tip of the braces 2 is pressed against the corner portion on the opposite side of the framework 1 to be installed. Therefore, it is not necessary to cut the length of the brace 2 with such a precise dimension, and no skill is required for construction. Further, even if the brace 2 is dried and contracted and a gap is formed between the tip 2a and the corner 3 of the frame, the gap can be easily filled by advancing the screw rod 20. Further, a supporting member 16 for supporting one end of the braces 2
Is pivotally supported by an L-shaped seat 11 fixed to a corner portion 3 of the frame 1, so that it can be used for the frame 1 having various shapes.

【Example】

FIG. 1 is a perspective view showing an embodiment of a fixing metal fitting of the present invention. In the figure, 11 is an L-shaped seat having two seating surfaces 11a and 11b orthogonal to each other, and is an inner lower corner portion 3 (FIG.
(Refer to FIG. 2), the two seating surfaces 11a and 11b are fixed to the lower beam 6 and the pillar 8 respectively. 12 and 13 are brackets in a direction orthogonal to the two bearing surfaces 11a and 11b of the L-shaped seat 11.
It is welded and integrated inside. One of the brackets 13 is a reinforcing plate 14 that is welded to the side edge of the L-shaped seat 11 and has its extending portion fixed to the side surfaces of the beam 6 and the pillar 8.
A large number of through holes for inserting fixing nails and fixing bolts are bored therethrough. 15 is a spindle installed between brackets 12 and 13, 16 is a spindle 15
It is a support member pivotally supported by. The support member 16 extends in a direction that bisects the included angle of the two seat surfaces 11a and 11b of the L-shaped seat 11. The support member 16 has a base end portion into which the support shaft 15 is inserted and has a square tubular shape, and the distal end side has a U-shaped cross section in which one side wall of the square tubular member is removed to form an opening surface 18, and the distal end has a striated shape. It is a receiving part 17 that receives the end of the paddle. A plurality of long holes 28 that are long in the extending direction of the support member are bored in the side wall of the support member 16 in the portion forming the receiving portion 17. On the support shaft 15 side of the receiving portion 17, there is provided a bottom plate 19 which is movable back and forth in the extending direction of the support member 16. A base end of a screw rod 20 in the extending direction of the support member 16 is welded to the center of the rear surface (face on the support shaft 15 side) of the bottom plate 19, and a nut 21 is screwed to the screw rod 20. An immovable plate 22 is welded to the side of the support member 16 closer to the support shaft 15 than the bottom plate 19, and the seat surface of the nut 21 is in contact with the immovable plate 22. The tip 20a of the screw rod passes through a through hole (not shown) provided at the center of the immovable plate 22 behind the immobile plate 22 (the support shaft 15
Side). Next, a method of using the fixing fitting according to the present invention will be described with reference to FIGS. 2 and 3. First, the L-shaped seat 11 is attached to the inner lower corner portion 3 of the frame formed by the lower beam 6 and the pillar 8 and fixed with nails or the like, and the reinforcing plate 14 is further fixed with the bolt 24 or the nail 25. Fix at 8. Next, the base end of the braces 2 whose tip is cut like a sword and whose base end is cut in the direction perpendicular to the longitudinal direction is fitted into the receiving portion 17 at the end of the supporting member, and the nail 26 is inserted through the long hole 28 in the side wall of the receiving portion. (The nails 26 and the braces can be relatively moved in the direction of the slot 28 by sliding the nails 26 if a strong force is applied to the receiving portions 17 and the braces), and the tips are stored inside the opposing upper corners 3. Then, a wrench is inserted into the opening surface 18 and the nut 21 is rotated to advance the screw rod 20, that is, the bottom plate 19 toward the facing upper corner portion. Due to the advancing operation of the bottom plate 19, the tip 20a of the bracing
Touches the upper corner portion 3 of the frame 1 without a gap, so a nail is driven into the tip 2a of the abutted braces from an oblique direction to fix the nail. If necessary, the loosening prevention nut 27 is screwed onto the screw rod 20 and fastened with a spanner to prevent the nut 21 from loosening. When the braces 2 thus constructed are dried and contracted before the wall coating work and a gap is created between the tip 2a and the upper corner 3 of the frame 1, the nut 21 is rotated again to rotate the screw rod 20 and After advancing the brace 2 upward so that the end of the brace is brought into close contact with the upper corner of the frame, the wall is painted.

[Effect of device]

As described above, according to the fixing bracket of the present invention, even if there is an error between the size of the braces and the diagonal dimension of the frame, the braces can be fixed to the frame without a gap, so that the braces are sufficient for the frame. The strength can be imparted, the labor for cutting the braces to an accurate length is not required, and skill is not required for the work. In addition, even if the braces dry and shrink and a gap is created between the tip and the frame, the gap can be easily filled by advancing the bottom plate of the receiving part, and the frame should have sufficient strength. You can Further, since the supporting member is pivotally supported on the L-shaped seat so as to be swingable, the supporting member can be used for frames of various shapes.
