Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device for fixing a beam for supporting a roof of a garage such as a carport, a motorcycle storage area, and a bicycle storage area, a building entrance and a roof of a corridor.

[0002]

[Problems to be solved by conventional techniques and devices]

 Normally, in carports, a roof structure is constructed by connecting the inclined beams with several pillars, and mounting and fixing the (main) house on the inclined beams. Some roof panels are fixed and have a sloping roof. The connection between the column and the beam in this carport is made by screwing the lower end of the inclined beam to the upper end of the column. In addition, for example, in a cantilever carport, in order to secure the strength to support the beam, a curved support is arranged at the corner where the column and the inclined beam intersect, and the support is attached to the column and the inclined beam. The roof is supported by this curved support. Instead of a curved support, a decorated, generally triangular bracket may be provided.

However, since a curved support and a bracket are provided corresponding to each support, these limit the effective height and effective area of the carport. For this reason, it may be an obstacle to getting the vehicle in and out, or it may be necessary to bend and avoid this when walking in the carport, and it is not always convenient to use. In addition, since a dead space is generated in relation to the vehicle, it is necessary to protrude the roof in the width direction or increase the height of the roof, and there is a problem that the installation space is easily expanded.

[0004] A similar problem exists not only in carports but also in a beam fixing device that supports the roof of a building entrance or a corridor. The present invention has been made in view of the above-mentioned problem, and it is possible to secure a sufficient space under the roof even with a small size without using a support, a bracket, etc. protruding under the roof, and to have excellent strength. The purpose of the present invention is to provide a beam fixing device for roof support.

[0006] In this aspect, for example, a plurality of frame-shaped structural members having an elliptical shape are connected and fixed with a plurality of connecting members, so that high structural strength can be achieved. Therefore, the conventional curved support and bracket for the corner can be eliminated, and a large space below the roof can be secured while saving space. In particular, the screw fasteners for fastening the screws for fixing the joints to the hollow column and the hollow beam, respectively, also function as a connecting member that connects the frame members to improve the strength of the entire joint. It is preferred in that respect. Also, with this type of screw fastening member, it is possible to inexpensively cope with various types of beam fixing devices simply by changing the position of attachment to the frame structural material or the position of the screw hole. it can. In addition, since the bent portion of the joint is reinforced by the reinforcing material, the strength can be remarkably improved.

[0007] It is preferable that the reinforcing member includes a reinforcing member that connects both sides of the framed structural member with the bent portion interposed therebetween to form a triangle having the bent portion as a top. This is because the bent portion of the frame structural material receives the highest bending moment, but by forming a triangular structure with the bent portion as the top, it is possible to obtain high structural strength that can face the high bending moment. Because. Further, the reinforcing material is a reinforcing cover formed by combining and fixing a hollow cover that covers the periphery of one piece of a hook-shaped or elliptical joint and a hollow cover that covers the periphery of the other piece.

Referring to FIG. 2 and FIG. 3, the joint 3 is provided with four long framed structural members 5 having a rectangular shape (or a hook) corresponding to the outer shape of the joint 3. I have. In the present embodiment, description will be made on the assumption that the frame structural member 5 is a bar having a round cross section. However, the frame structural member 5 may be a so-called deformed steel bar, a bar having a square cross section, a round bar having a cross section. It is possible to use a rectangular or square tube material, or an angle or channel shape plate material. Each frame structural member 5 is arranged at four corners of a rectangular cross section formed by the joint fitting 3. Each framing structural material 5 has a first piece 5a and a second piece 5b, and the first piece 5a of each framing structure material 5 has, as shown in FIG. 2 and FIG. The hollow pillar 2 having a rectangular cross section is fitted along the corresponding corner of the open end 2a. Similarly, as shown in FIGS. 2 and 4 (b), the second piece 5b of each skeleton structural member 5 extends along the corresponding corner of the open end 4a of the hollow beam 4 having a rectangular cross section. It is to be inserted. Although not shown, for example, a pipe having a rectangular cross section surrounding the ends of the plurality of frame structural members 5 and fixing them is provided in order to perform the fitting smoothly. The beam 4 may be inserted into the open ends 2a, 4a.

Referring to FIG. 4A, a first piece 5a of each frame structure member 5 is fitted into a notch recess 6a at each of four corners of a first connecting member 6 formed of, for example, a rectangular plate, and is welded. It is fixed by. As shown in FIG. 3, the first connecting members 6 are provided at a plurality of positions at a distance from each other, thereby improving the strength so as to form a box structure. Similarly, referring to FIG. 4 (b), the second piece 5b of each skeleton structural member 5 is fitted into a notch recess 7a at each of the four corners of the second connecting member 7 made of, for example, a rectangular plate. It is fixed by welding. As shown in FIG. 3, the second connecting members 7 are provided at a plurality of positions at a distance from each other, thereby improving the strength so as to form a box structure. Note that an angle material or a channel material may be used as the first and second connecting members 6 and 7.

Referring to FIGS. 2 and 3, a screw fastening member 8 made of, for example, a rectangular plate is stretched between first pieces 5 a of adjacent frame structural members 5 and fixed by welding. . A screw hole 8a is formed at a required position of the screw fastening member 8. The first piece 3a of the welding tool 3 and the hollow support 2 are fixed by screwing the screw 9 passing through the screw insertion hole 2a of the hollow support 2 into the screw hole 8a. Similarly, a screw fastening member 10 made of, for example, a rectangular plate is stretched between the second pieces 5b of the adjacent frame structural members 5 and fixed by welding. A screw hole 10a is formed at a required position of the screw fastening member 10. The screw 11 that has passed through the screw insertion hole 4a of the hollow beam 4 is screwed into the screw hole 10a, so that the second piece 3b of the joint fitting 3 and the hollow beam 4 are fixed.

The screw holes 8 a and 10 a may be formed directly in the holes provided in the screw fasteners 8 and 10, but the nuts connected to the holes provided in the screw fasteners 8 and 10 may be formed by projecting welding the screw fasteners. It may be fixed to 8, 10. Further, referring to FIG. 3, a bent portion 3c formed by first piece 3a and second piece 3b of joining fitting 3 has a triangular shape having bent portion 3c as a top in side view using reinforcing material 12. And the structural strength of the bent portion 3c is remarkably increased. Specifically, the reinforcing member 12 is made of a bar, a tube, or a plate connecting the first and second connecting members 6, 7 near the bent portion 3c to each other. Both ends of the reinforcing member 12 are fixed to the corresponding first and second connecting members 6 and 7 by welding.

When the ends of the first piece 3 a and the second piece 3 b of the joint 3 are fitted into the corresponding hollow column 2 and hollow beam 4, the first and second parts close to the bent portion 3 c Positioning projections 6b provided on the side edges of the connecting members 6, 7 abut against the corresponding open ends of the hollow column 2 and the hollow beam 4, thereby restricting the fitting position of the fitting 3. When the joint 3 is fitted into the hollow column 2 and the hollow beam 4, the intermediate portion including the bent portion 3c of the joint 3 remains without being fitted. As shown in FIG. 2, a cover 13 made of a synthetic resin is put on the remaining portion without being fitted. As shown in FIG. 5, the cover 13 is, for example, divided into two parts, a first cover 13 a having an elliptical shape in a side view and a groove shape in cross section, and a second cover 13 b made of a plate having an elliptical shape in a side view.
