Description

[Detailed description of the invention] << Industrial application field >> This invention relates to a metal fitting used to reinforce a dwarf, a lintel and other rungs provided at the upper side of the opening of a wall having Japanese walls on both sides. It is.

<< Conventional Techniques and Problems >> Kamoi and lintels in conventional wooden buildings are mortise-jointed to pillars at both ends, and are fixedly supported at the lower ends of studs suspended from beams. However, timber often becomes out of order, and the deflection due to the load is large. Therefore, in a snowy area or a wet area, distortion occurs in the Kamoi and the lintel within one to two years after construction, and the center of the Kamoi descends and twists due to the snow load. As a result, there have been many problems such as a problem in opening and closing the sliding door. If the distortion of the Kamoi is severe,
The sliding door cannot move, the sliding door cannot be removed, and the load applied to the sliding door causes the glass fitted in the sliding door to be broken by a slight impact.

Various reinforcing metal fittings and structures are used in buildings, but no reinforcing metal fittings that can effectively prevent distortion such as Kamoi or lintel are known.

《Problems to be solved by the invention》 This invention solves the above-mentioned problems, especially the reinforcement that can completely prevent distortion and deformation of rungs such as lintels, lintels, etc. of walls with Japanese style walls on both sides. It is an object of the present invention to obtain a metal fitting which is easy to construct, does not impair the aesthetic appearance of the wall surface, and does not interfere with other construction work such as installation of a barbed.

<< Means for Solving the Problems >> The reinforcing bracket of the present invention includes a band plate 6 forming a horizontal surface,
An end face plate 7 erected from both ends of the strip plate, a girder plate 8 having both ends and a lower side fixedly integrated with the end face plate 7 and the strip plate 6 to form a vertical surface; And a receiver 10 attached to the upper edge of the building. The strip 6 is attached to and fixed to the upper surface of the crossbar at the upper edge of the opening of the building, and the end plates 7 are provided on both sides of the opening. The receiving device 10 is attached to and fixed to a side surface of the pillar 1 and is used by being fixed to a frame such as a stud or a punch provided in a wall body above the opening. The fixing bracket of the present invention can be entirely made of an iron plate, a stainless plate, an aluminum plate or the like having a thickness of about 3 mm, and can provide sufficient rigidity to reinforce the crosspiece 2.

<< Operation >> In the reinforcing metal fitting 5 having the above structure, the strip 6 resists the horizontal distortion of the crosspiece 2, the girder 8 resists the vertical distortion, and both 6, 8 resist twisting and contraction. . And since this metal fitting 5 fixes the crossbar 2 by firmly fixing both ends to the pillar 1, the rigidity of the reinforcing metal fitting 5 becomes extremely high,
Therefore, the bracket 5 does not become excessively heavy,
And a strong resistance to horizontal, vertical and torsional strains, and the column 1 can also prevent the displacement of the entire crosspiece 2.

The reinforcing metal fittings 5 can be manufactured at low cost by a welding structure, are embedded in the Japanese walls on the upper and lower sides of the crosspiece, and can be provided with perforations and the like by providing perforations in the reinforcing metal fittings 5 appropriately. There is no problem in mounting.

<< Embodiment >> FIG. 1 is a side view of a reinforcing metal fitting according to the present invention, and FIG. 2 shows a state in which the reinforcing metal fitting of the present invention is mounted on a doorway of a wall that partitions a Japanese-style room. In the figure, reference numeral 1 denotes a pillar of a building, 2 denotes a pillar 1, a dumbbell erected between the 1 and 3, 3 is a sill sill provided in parallel with the lintel 4, and 4 is divided by a pillar 1, a sill 2 and a sill 3 The wall 5 is a reinforcing metal fitting of the present invention. FIGS. 1 and 3 to 7 show the details of the reinforcing metal fittings 5, 6 is a band plate, 7 is an end face plate erected from both ends of the band plate 6, and 8 is both ends and a lower side. 10 is a girder plate having a T-shaped cross section welded to the end plate 7 and the band 6, 9 is a square displacement absorbing material disposed on the upper surface of the girder plate 8 at a predetermined interval, 10
Is a horizontal U-shaped receiver fixed to the upper end of the displacement absorbing member 9. The strip plate 6 and the girder plate 8 of the illustrated embodiment are formed by back-to-back welding of U-shaped cross sections having narrow upper flanges. The displacement absorbing member 9 is made of a sheet metal bent in a trapezoidal shape, a receiving member 10 is fixed to an upper end thereof, and a long hole formed in a bottom plate thereof.
It is attached to the upper surface of the girder member 8 by bolts (not shown) inserted through 11, and the slanted side plate of the sheet metal bent into a trapezoid absorbs the vertical displacement of the receiving member 10 by bending.
The lateral displacement caused by the bending of the slanted side plate is absorbed by sliding the bottom plate in the left and right direction in FIG. Reference numeral 12 denotes an auxiliary plate provided at the center of the reinforcing metal member 5, which is provided for connecting the metal member 5 and the hanging bundle 20.

As shown in FIG. 3, the reinforcing metal fitting 5 is placed so that the girder plate 8 is located substantially at the center of the Kamoi 2 in the width direction.
A bolt (not shown) that penetrates the column 1 is inserted into the bolt insertion hole 13 and firmly fastened with a nut or the like. Reference numeral 14 denotes a notch provided to avoid interference between the beam 8 and the bolt. The end face plate 7 is further fixed to the column 1 by inserting a wood screw into the screw hole 15 thereof.

Reinforcing bracket 5 thus firmly fixed between columns 1 and 1
Is fixed to the gate 2 by inserting a wood screw through the mounting holes 16 formed in the strip 6 and the base material 17
Is fixed. Studs 18 suspended from the transom sill 3 erected in parallel above the Kamoi 2 are connected to the base material 17 at their lower ends.

When the hanging bundle 20 is connected to the Kamoi 2, the split groove 19 is cut into the lower end of the hanging bundle 20, and the girder plate 8 of the corresponding part of the reinforcing bracket 5 is removed from its upper surface plate and the reinforcing plates 12 are provided on both sides. It is fixed, and the hanging bundle 20 is inserted between the auxiliary plates 12 and 12 with a slight gap 21 between the lower surface of the hanging bundle 20 and the deep end of the split groove 19 and the upper edges of the band plate 6 and the girder plate 8. Then, the nail 23 is inserted into the long hole 22 formed in the auxiliary plate 9.
To fix the hanging bundle 20 in a structure that allows a slight downward movement.

The wall portion 4 is formed by nailing a punch through a through hole 24 formed in the girder plate 8 and attaching a lath board. If necessary, a spine will be attached.

In addition, although the reinforcing metal of the illustrated embodiment is for two, an auxiliary plate is provided at the center of the metal to fix the hanging bundle.
The auxiliary plate is not required for one-time use.

<< Effects of the Invention >> As described above, according to the auxiliary metal fittings of the present invention, it is possible to completely prevent distortion and deformation of the rung such as Kamoi, lintel, etc. Since it is buried in the wall, it does not impair the aesthetic appearance of the Japanese-style wall, and does not hinder any other work such as the interior decoration of the wall or the installation of the bark. Therefore, there is no distortion due to the duck at the upper edge of the opening due to snow load or the like, and there is no problem in opening and closing the sliding door.
