Description

[Detailed description of the invention] <Industrial application field> This invention relates to the reinforcement structure of wooden buildings, and is used to strengthen the crossbeams of the wall openings of wooden buildings, such as lintels, lintels, and sills. This relates to a structure reinforced with a sheet metal structure.

<Prior Art and Problems> In conventional wooden buildings, lintels are supported by having both ends tenoned to pillars, and the middle part fixed to the lower ends of studs hanging from the beams. However, wood often warps and bends significantly under load, so lintels and lintels can become distorted within one to two years after construction, especially in snowy areas or wet areas, causing the center of the lintel to drop or twist due to the snow load. This caused many problems such as difficulty in opening and closing the sliding doors. If the lintel is severely distorted, the sliding door will no longer move, it will be impossible to remove it, and even the glass fitted into the sliding door will break at the slightest impact due to the load placed on the sliding door. arise.

Although various reinforcing metal fittings and reinforcing structures are used in buildings, there are no known reinforcing structures or metal fittings that can effectively prevent distortion of lintels, lintels, etc. at wall openings as described above.

《Problems to be solved by the invention》 This invention aims to solve the above problems, namely,
The goal is to create a reinforcing structure that can completely prevent distortion and deformation of cross beams such as lintels, lintels, and sills installed above and below the wall openings of wooden buildings, and is easy to construct. The object of the present invention is to obtain the above-mentioned reinforcing structure that does not impair the aesthetic appearance of the building and does not cause any hindrance to other construction works such as wall interior decoration and eaves installation.

<Means for Solving the Problems> In the structure of this invention, the crossbeams 2 such as lintels, lintels, and middle sills in the wall openings of wooden buildings are attached to the pillars 1, 1 on both sides with sheet metal structures 5, It has a structure that is firmly fixed with 24 screws.

The sheet metal structures 5 and 24 have a strip plate 6 forming a horizontal surface, an end plate 7 erected upward from both ends of the strip plate, and both end sides and a lower side fixedly attached to the end plate 7 and the strip plate 6. girder plate 8 which is bent to form a vertical surface;
25, and an auxiliary plate 9 fixed and erected at the intermediate part of the girder plates 8 and 25, the strip plate 6 is attached and fixed to the upper surface of the cross beam 2, and the end plate 7 is attached to the side surface of the column 1. The auxiliary plate 9 is attached and fixed to the vertical surface of the stud 10. The sheet metal structures 5, 24 can be made entirely of iron plates, stainless steel plates, aluminum plates, etc. with a thickness of about 3 mm, and can be provided with sufficient rigidity to reinforce the crossbeam 2.

The lower sides 8a, 25a of the girder plates 8, 25 are preferably arcuate sides with the center slightly (several mm) recessed upward. The stud 10 and the auxiliary plate 9 are connected in a structure that allows the stud to move slightly, and the end plate 7 is attached to the column 1.
The strips 6 are each firmly fixed to the crossbeams 2. The direction of movement of the studs and the auxiliary board is downward when reinforcing an upper cross beam such as a lintel, and upward when reinforcing a lower cross beam such as a sill.

<<Function>> In the sheet metal structures 5, 24 having the above structure, the strip plate 6 resists distortion in the horizontal direction of the cross beam 2, the girder plates 8, 25 resist distortion in the vertical direction, and both 6, 8 or 25
resists twisting and contraction. Since both ends of the sheet metal structures 5, 24 are firmly fixed to the pillars 1 to fix the crossbeams 2, the sheet metal structures 5, 24
The rigidity of the crossbeam 2 is extremely high, and therefore the sheet metal structures 5 and 24 do not become excessively heavy, exhibiting strong resistance to the above-mentioned distortion, and distortion of the entire crossbeam 2 can be prevented by the pillars 1. .

On the other hand, the sheet metal structures 5 and 24 maintain a connection relationship with the studs 10 through their auxiliary plates 9. For example, even if the beams and therefore the studs 10 descend due to snow loads, this descent will be caused by the sheet metal structures. 5 and 24, and even if the beam is bent due to the snow load, this bending will not be transferred to the lintel or the like. And girder plate 8,
By making the center of the crossbeam 25 a slightly concave arc-shaped side, the center of the crossbeam 2 can be made slightly open, and the sliding door can be opened and closed more smoothly.

The sheet metal structures 5 and 24 can be manufactured at low cost by welding, and are buried in the walls above and below the crossbeams, so they do not appear on the inside and outside of the building.
By appropriately providing perforations in the sheet metal structures 5 and 24, problems in fixing wall base materials, eaves, window frames, etc. can be avoided.

《Example》 Figures 1 to 3 show the first example of the present invention, and illustrate the reinforcing structure of a window lintel installed in a wall that separates a Japanese-style room from a hallway or outdoors. be. 1 is a perspective view, FIG. 2 is a view taken along the arrow X in FIG. 1, and FIG. 3 is a plan view with an intermediate portion omitted. In the figure, 1 is a pillar of the building, 2 is a lintel built between pillars 1 and 1, 3 is a lintel installed parallel to the lintel 2, and 4 is a pillar 1, a lintel 2, and a lintel 3. Divided opening, 5 shown overall is 3mm
A sheet metal structure made of a thick iron plate, 6 is a band plate of the structure, 7 is an end plate erected upward from both ends of the band plate 6, and 8 is attached to both end sides and the bottom side of the end plate 7 and the band body. 6, the center of its lower side 8a is slightly recessed upward. 9... is an auxiliary plate fixed to the middle part of the girder plate 8, and 10 is a stud hanging from a beam (not shown), the lower end of which is inserted between the auxiliary plates 9, 9.

The sheet metal structure 5 is placed so that the girder plate 8 is located approximately at the center in the width direction of the lintel 2, and the bolt 12 passing through the column 1 is inserted into the bolt insertion hole 11 of the end plate 7, and the nut 13 is inserted. It is firmly fixed. 14
is a notch to avoid interference between the girder plate 8 and the bolt 12. Reference numeral 15 denotes a wood screw that is inserted into the screw hole 16 of the end plate 7 to supplementally fix the end plate 7 to the column 1.

The sheet metal structure 5, which is firmly fixed to the pillars 1, 1 through the end plate 7, is attached to the lintel by inserting the wood screws 18 into the mounting holes 17 made in the strip plate 6. Fixed to 2. Since the girder plate 8 is manufactured by slightly recessing the center of its lower side 8a upward,
The lintel 2 is slightly curved upward along the lower side 8a of the girder plate, that is, along the band 6, so that the center of the lintel is slightly raised. The stud 10 is attached to the auxiliary plate 9, with a slight gap 19 between its lower end and the strip plate 6.
A long hole 20 is inserted between the holes 20 and 20 formed in the auxiliary plate 9.
It is fixed in such a way that it can be moved slightly downward by driving nails 21 into it.

The surfaces of the studs 10, pillars 1, and lintels 2 facing outdoors are located on one plane as shown in FIG.
