[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an L-shaped metal object used to fix members that are joined at substantially right angles such as columns and horizontal members in a wooden structure such as a house, and in particular, it can be deformed even when a large force acts between the members. The present invention relates to an L-shaped metal piece that is unlikely to occur.

[0002]

[Prior art]

 Conventionally, in a house or the like, a plate-shaped member made of metal is bent into an L-shape as a means for fixing a portion where members are joined at a substantially right angle such as a pillar and a body difference, a pillar and a base, and a base and a large pull. Mold hardware is widely used. In this L-shaped metal object, for example, the apex angle of the L-shaped portion is matched with the right angle surface generated by abutting the side surface of the column and the end surface of the horizontal member, and one plate-shaped portion sandwiching this apex angle is fitted. On the side surface of the pillar, the other plate-shaped part is fixed to the horizontal member by bolts, nails, screws, etc., and the pillar and the horizontal member are fixed at a substantially right angle.

However, in such an L-shaped metal piece, deformation is likely to occur due to a tensile force generated between the joining portions, and there is a possibility that a gap may be formed at the joining portion or a member may drop off. This is because the L-shaped metal member has a structure in which the plate member is bent into an L-shape, and the L-shaped metal member is easily bent and deformed by a tensile force.

In order to solve such a defect, a plate-like member that connects both L-shaped edges is attached to one side edge portion of the bent L-shaped metal piece to reinforce the bent portion. It is possible to do Such a plate-shaped member, that is, a rib for reinforcement is generally attached to an L-shaped metal member by welding.

[0005]

[Problems to be solved by the device]

 However, the L-shaped metal fitting of the type in which the ribs are attached by welding as described above has a problem that the welding process is troublesome, the manufacturing is troublesome, and the cost is high. The present invention has been made in view of the above problems, and an object thereof is a strong L-shaped metal piece that is resistant to deformation and can be easily manufactured by a simple process. An object of the present invention is to provide a device that can be easily installed.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the L-shaped metal article according to claim 1 has a substantially rectangular base portion made of a metal plate, a sub-base portion vertically bent from one edge of the base portion, and the base portion. Is bent vertically from the adjacent side that is perpendicular to the edge on which is erected, and is bent vertically from the rib by a fold line that is perpendicular to the fold lines of both the base and the sub-base, and the sub-base And a superposition portion superposed on each other, and a through hole whose center is substantially coincident with the sub-base portion and the superposition portion is provided.

According to a second aspect of the present invention, in the L-shaped metal article according to the first aspect, the through hole and the center are formed on a surface of the sub-base portion or the polymerization reinforcing portion on a side where the rib is provided. It is assumed that the nuts are joined so that they are almost the same.

In the above L-shaped metal article, the rib can have an appropriate shape, size, and the like as long as it has a structure that forms a surface that is erected perpendicularly to both the base portion and the sub-base portion. Further, the bending line is set so that the sub base portion and the superposition reinforcement portion are superposed on each other with almost no gap. The polymer reinforcing portion is formed by bending a surface continuous with the rib, and even if the polymer reinforcing portion comes to the side provided with the rib when it is superposed on the sub-base portion, the rib is provided. Even a structure in which the side opposite to the closed side is located can be set appropriately. Through holes can be appropriately provided in the base so that the base can be fixed to a structural member such as a pillar or a horizontal member by a suitable means such as a bolt, a screw, or a nail. In addition, one or a plurality of through holes whose centers are substantially coincident with each other can be provided in the superposed sub-base portion and the superposition portion, and the size of the through holes can be appropriately set according to the application.

Further, in the L-shaped metal article according to claim 2, the nut attached to the rib-side surface of the sub-base portion or the polymerization reinforcement portion is preliminarily welded or glued to the L-shaped metal article. They are joined together and can be screwed into bolts that penetrate columns or cross members.

[0010]

[Action]

 The L-shaped metal article according to claim 1 is attached as follows at a portion where structural members such as columns and horizontal members are joined. The apex angle of the L-shaped metal object is brought into contact with the portion where the structural members to be joined form a right angle, and the base portion is fixed to one of the structural members to be joined by an appropriate means such as a bolt, a screw, or a nail. Then, the sub base is fixed to the other structural member with bolts, screws, nails or the like.

The L-shaped metal piece thus attached is continuous in a state where the rib is bent to the base portion and the superposition reinforcement portion, and the superposition reinforcement portion is superposed on the sub base portion, so that the base portion is not bent and deformed. It is reinforced so that it does not occur, and bending deformation is also prevented in the superposition reinforcement part and the sub-base part, and the vertical angle with the base part is also maintained without deformation. Therefore, the structural members that are joined substantially vertically are firmly fixed even when a force in the direction of separating them is applied, and the members are firmly joined without forming a gap or dropping out at the joint. Further, since the rib is formed by bending the metal plate material, it can be easily manufactured without requiring a skillful work such as welding or a laborious process. Further, since the above-mentioned sub-base portion and the polymerized reinforcement portion have a double-layered structure, when a bolt is fixed to a pillar, a horizontal member, etc., the bearing capacity of the washer is increased and it can be firmly fixed. .

In the L-shaped metal article according to claim 2, the surface of the sub-base or the polymerization-reinforcing portion on the side provided with the ribs is aligned so that the centers thereof substantially coincide with the through holes of the sub-base and the polymerization-reinforcing portion. Since the nut is joined, the work of attaching and fixing the L-shaped metal object can be performed simply and efficiently by screwing the bolt that penetrates the pillar, the horizontal member, and the like.
