Description

[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention relates to a beam receiving member used to mount a beam, which is always used in a wooden structure, to a girder, a body difference, etc. Regarding the beam receiving material used at the time.

[0002]

2. Description of the Related Art One of the inventors of the present invention previously applied for a beam structure for a wooden building and put it into practical use (for the application, see Japanese Patent Application No. 3-89812). In this known beam receiver, a plate member is formed into a planar U-shape to form a fitting portion having an abutting portion, and horizontal plates are provided at lower edges of opposite side plates of the fitting portion. In the above structure, a downward plate is provided on an end edge of the fitting portion on the side opposite to the abutting portion to form an engaging portion, and mounting holes are formed in the fitting portion and the engaging portion, respectively. This beam receiving object has achieved results that have not been obtained so far, such as streamlining of beam mounting work, safety of the beam mounting work, and firm mounting form at the proper position of the beam.
Although these results have been obtained for small beams,
We found that the mounting stability of large beams (for example, about 33 to 45 cm) was not satisfactory. The present invention aims to eliminate such difficulties, and even large beams, like small beams, is designed to improve the efficiency of the mounting work, the safety of the work, and a firm mounting form for the proper position of the beam. In addition to these, it is an object of the present invention to provide an improved beam receiving member capable of stably attaching a large beam to a girder, a body difference or the like.

[0003]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the means of the present invention is to form a plate material into a U-shape in a plan view and an L-shape in a longitudinal cross-section to form an abutment part and an abutment part. A fitting portion having a bottom portion is configured, and horizontal plates opposite to each other are provided at lower edge portions of the facing side plate of the fitting portion, and in the horizontal plate, the abutting portion side edge of the fitting portion and the abutting portion. That is, the downward plates are provided at the end edges on the opposite side to the engaging portions to form the engaging portions, and the fitting portions and the engaging portions are provided with mounting holes.

[0004]

[Operation] After the side view inverted channel type engaging portion is engaged across the girder or the body difference, it is arranged at the beam attachment position, and is attached and fixed to the girder or body difference using the attachment hole of the engagement portion. To do. The beam is arranged at a predetermined mounting position by fitting the end portion of the beam into the fitting portion, abutting against the abutting portion and simultaneously placing the beam on the bottom portion. Then, if the beam is attached and fixed to the fitting portion using the attachment hole of the fitting portion, the beam is arranged at a predetermined attachment position. The beam arranged at a predetermined position is such that the engaging portion is engaged and fixed by straddling the girder or the body difference, and the end portion of the beam itself is an abutting portion of the fitting portion.
By being attached and fixed by being surrounded by the opposite side plates and the bottom except for the upper surface, it can be firmly attached without rattling the girder or the body difference.

[0005]

[Examples] As the plate material, steel materials such as iron materials and stainless steel plates are preferable in terms of workability and durability, but the material is not limited.

The fitting portion A is formed by bending a plate material into a plane U shape.
The striking portion A1 for the beam D, the bottom portion A2 and the facing side plate A3 are formed. The bending dimension of the fitting portion A is determined according to the thickness dimension of the beam D so that the end portion of the beam D can be fitted from the opening on the side opposite to the hitting portion A1 or the opening on the upper side. To form. Then, an appropriate number of mounting holes C are formed in the facing side plate A3, and the beam D can be mounted by using through bolts.

The engaging portion B is formed in a side view inverted channel shape by a horizontal plate B1 and a downward plate B2 which is vertically installed to face the horizontal plate. The engaging portion B is integrally bent at the lower edge of the opposite side plate A3 of the fitting portion A, but when this forming means is difficult, the horizontal plate B1 and the downward plate B2 are folded. After bending, one side edge of the horizontal plate B1 is welded to the lower edge of the opposing side plate A2 of the fitting portion A to be integrally formed with the fitting portion A. And
The horizontal plate B1 and the downward plate B2 are each provided with an appropriate number of mounting holes C so that they can be mounted on the girder F with bolts and nuts.

The beam receiving member constituted by the fitting portion A and the engaging portion B is not so large in size, is lightweight, and has a structure that is easy to handle.

When the beam D is mounted on the girder F, the engaging part B is engaged by straddling the girder F, the position is corrected and the beam is arranged at a predetermined beam mounting portion, and the engaging part B is mounted. Tighten a bolt into the hole C and tighten it with a nut to attach it to the girder F. Then, the end portion of the beam D is fitted into the fitting portion A and abutted against the abutting portion A1, so that
2 Place it on the top and place it in the specified mounting area. Then, a through bolt is screwed into the mounting hole C of the fitting portion A and tightened with a nut to attach the beam D to the fitting portion A and fix the beam D to the girder F.

Reference numeral c in the drawing is a temporary fixing hole,
Used for temporary fixing by nailing until it is fixed with a nut. Further, reference numeral E is a reinforcing plate provided over the fitting portion A and the engaging portion B.

[0011]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, it is possible to dispose the beam receiving member by mounting and mounting the beam, without moving the heavy large beam at the mounting position. Can be placed at the attachment site. Therefore, it is not necessary to arrange the beams, the work efficiency is promoted, the risk of injury is reduced, and the work can be performed safely. The beam can be firmly and stably attached without rattling due to the beam receiving member and without fear of positional displacement.
