Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner portion of a wooden frame which enhances the strength of the wooden frame against horizontal force to prevent shear deformation thereof, and enables a space to be formed in a relatively long span in the wooden frame. For wood reinforcement members for
In addition, by using the wooden reinforcement material for the corner part, the joint strength of the braced ends to the pillars etc. is improved to prevent the braces from being stepped out of the plane and to prevent the columns and cross members from being crushed or torn by the braces. The present invention also relates to a bracing method for improving the fire resistance of a wooden frame.

[0002]

2. Description of the Related Art In order to increase the strength of a wooden frame against horizontal force applied by a typhoon or an earthquake, etc., and to prevent shear deformation of the wooden frame during a typhoon, an earthquake, etc., a conventional wooden frame is used. As shown in FIG. 8, a bracing 3 is provided at a diagonal position of a frame-shaped wall set composed of a pillar 1 made of a wooden structure and a horizontal member 2 such as a base, a beam, a girder, or the like. In a wall set in which no bearing wall or a bearing wall is provided in order to provide a bearing wall or a window frame along with the set, as shown in FIG. In addition, a fire beam 5 is provided at a corner where the horizontal members 2 are joined to each other as shown in FIG.

[0003]

However, since the material of the sword 4 and the blow beam 5 which are reinforcing members for the corner portions of the conventional wooden frame are ordinary wood, the strength of the wooden frame is sufficiently increased. In order to increase the length of the truss 4 and the blow beam 5 from the joining position between the column member 1 and the lateral member 2 and the joint position between the lateral members 2 to the column member and the lateral member, 4
It is necessary to lower the pulling force and the compressive force applied to the fire beam 5 by the horizontal force on the wooden frame by separating the joining position of the fire beam 5 and the conventional method. As shown in FIG. 9, a large projection over the inside of a frame-shaped wall set composed of the column member 1 and the horizontal member 2 is provided.
There are problems that the ceiling surface 6 is prevented from being raised, and that a large window frame is prevented from being provided.

[0004] Further, as shown in FIG. 10, a conventional fire striking beam 5 also protrudes greatly into the inside of a frame-shaped floor set or ceiling set made of a horizontal member 2 so that piping and wiring under the ceiling and under the floor can be performed. There has been a problem that the arrangement thereof when they are provided is greatly restricted.

[0005] The conventional bracing 3 is reinforced with a reinforcing metal 7 such as a bracing plate which is nailed to the surface of the wood with nails or the like as shown in FIG. When a large tensile force or compressive force is applied to the bracing 3 due to the horizontal force on the wooden frame,
The reinforcing metal 7 is peeled off from the column member 1 or the horizontal member 2, and the bracing 3
There is a problem that the out-of-plane stepping-off occurs, or the reinforcing metal 7 is peeled off from the braces 3 and the column members 1 and the lateral members 2 are crushed or torn by the braces 3.

Further, as described above, the reinforcing metal member 7 is not provided inside the pillar member 1, the lateral member 2, or the bracing 3, which is a wooden structural member, but is nailed on the surface thereof, so that a fire may occur. In such a case, there is a problem that the material is softened and the strength is reduced before the column material or the like. In other words, the burning temperature of wood is lower than the softening temperature of metal, but in the case of wood such as pillars, the surface burns and is ashed and carbonized, but the inside is easily ashed and carbonized. Therefore, in the event of a fire, a phenomenon was observed in which the reinforcing metal member 7 on the surface softened first. The dew condensation on the surface of the reinforcing metal member 7 causes corrosion of the reinforcing metal member 7 itself and the wood that is in contact with the reinforcing metal member 7, and the column material 1
Also, there is a problem that the durability of the joint portion of the bracing 3 to the horizontal member 2 is reduced.

[0007]

SUMMARY OF THE INVENTION The present invention provides a wooden reinforcing member for a corner portion of a wooden frame which advantageously solves the above-mentioned problems, and a bracing method using the same. A wooden reinforcing member for a wooden frame corner portion of the present invention is a wooden reinforcing member for reinforcing a corner portion where wooden structural members of a wooden frame are joined to each other.
The wooden reinforcing member is formed of a compressed material, more preferably a compressed aggregate.

[0008] According to such a wooden reinforcing member, since it has a high tensile and compressive strength as compared with ordinary wood, when it is used as a slab or a fire beam, the wooden structural members are joined together. Position of the wooden frame and the joint of the stake beam away from the position, and the horizontal force on the wooden frame does not reduce the tension or compression force applied to the sway or the stake beam. Since the proof strength can be sufficiently increased, it is possible to join a stake or a fire beam to the wooden structural material adjacent to the joint position between the wooden structural materials.

Therefore, if the wooden reinforcing member of the present invention is used as a slab, the overhang of the siding to the inside of the frame-shaped wall set composed of the column member and the horizontal member is reduced, and the ceiling surface is reduced. It can be raised or provided with a large window frame, and if the wooden reinforcing member of the present invention is used as a fire beam, a fire beam can be provided inside a frame-like floor or ceiling frame composed of horizontal members. Since the overhang is reduced, it is possible to reduce restrictions on the arrangement of piping, wiring and the like under the ceiling and under the floor.

[0010] In addition, according to the above-mentioned wooden reinforcing member, since it is wooden rather than metal, even in the event of a fire, the inside does not ash or carbonize and remains together with the wooden structural members such as pillars. Thus, it is possible to continuously reinforce the joint between the wooden structural members.

The wooden reinforcing member of the present invention may be a diagonal member having a conventional general shape of a toe or a fire beam, but more preferably, a right angle close to a joining position of the wooden structural members. And a substantially L-shaped or triangular or more convex polygonal member having the following corners.

[0012] If the shape of the wooden reinforcing member is a shape having right-angled corners which are in close contact with the joining positions of the wooden structural members, the surfaces formed by the wooden structural members joined to each other, that is, the wall and floor sets are formed. The cross-sectional area of the wooden reinforcing member in the extending direction of the surface can be increased, and the strength of the wooden frame can be sufficiently increased while suppressing the protrusion of the wooden reinforcing member to the inside of the frame-shaped wall set or floor set. .

Further, the wood reinforcing member of the present invention has a groove on a side opposed to a right-angled corner close to a joining position of the wood structural members. If such a groove portion is used at a corner portion of a frame-like wall set composed of a column member and a horizontal member, it faces toward the inside of the wall set.
The braced end can be fitted and fixed in the groove, and the braced end can be joined to the wooden structural material with high rigidity due to the high strength of the compressed material and its fitting structure. Even if a large tensile force or compressive force is applied to the braces due to the horizontal force on the wooden frame, the braces can be prevented from stepping out of the plane and the crushing or tearing of the column or horizontal member due to the braces can be prevented. Can be prevented.

Further, according to the above-mentioned wood reinforcing member, the end of the bracing can be fitted and fixed in the groove, so that even in the event of a fire, the inside of the pillar is not ashed or carbonized. It remains with the wooden structural member and can maintain the joint strength of the bracing to the pillars, etc. In addition, since it is made of wood, the corrosion to the pillars and the horizontal members due to the condensation due to condensation on the surface There is no reduction in the durability of the different joints.

The bracing method according to the present invention uses the above-mentioned wood reinforcing member having a groove on a side opposite to a right-angled corner close to a joining position of the wooden structural members, and has an end of a braid in the groove. According to this method, as described above, even when a large tensile force or compressive force is applied due to the horizontal force on the wooden frame, it is possible to secure the same. It can prevent the out-of-plane treading of the wood, and can prevent the crushing and tearing of pillars and cross members due to bracing.In the event of a fire, the inside of the wood reinforcing member does not ash or carbonize. It can remain together with the wooden structural members such as pillars, and maintain the joint strength of bracing to the pillars, etc.
In addition, since the wooden reinforcing member is made of wood, there is no possibility that the corrosion due to dew condensation on the surface lowers the durability of the joints of the braces to the pillars or the lateral members.
