Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting bracket for an outer wall panel and can be used in a unit type house constructed by joining a plurality of building units to each other.

[0002]

BACKGROUND ART Conventionally, a unit-type building constructed by joining various building units manufactured in a factory in advance to each other at a construction site has been used. According to such a unit-type building, most of the work relating to the interior and exterior of the building is completed at the factory, so the work at the construction site is reduced and the work can be done in a short period of time. As a unit type building, as shown in FIG. 3, a building unit 1 formed in a box shape.
There are some combinations. In the figure, a building unit 1 has a hexahedral frame 5 in which upper and lower ends of pillars 2 at four corners are connected by an upper beam 3 and a lower beam 4, respectively. Between the upper beams 3 along the long side direction of the frame 5,
A plurality of ceiling girders 6 are bridged, and a ceiling panel 7 is attached to the lower surface of these ceiling girders 6. On the other hand, a plurality of joists 8 are bridged between the lower beams 4 along the long side direction of the skeleton 5, and a floor material 9 is attached to the upper surfaces of these joists 8. Also, on the side surface of the frame 5 on the front side in the figure,
An outer wall panel 10 made of lightweight cellular concrete is provided. As shown in FIG. 4, the outer wall panel 10 has its upper end side joined to the upper beam 3 of the frame 5 via a bracket 40 and its lower end side joined to the lower beam 4 of the frame 5 via a bracket 41.

As shown in FIG. 5, a bracket 41 for mounting the outer wall panel 10 on the upper end side has a main body 42 formed by bending a metal plate material. The main body 42 is provided with a receiving portion 43 formed by horizontally bending the lower end portion. A joining metal piece 44 having an L-shaped cross section is welded to the upper end portion of the main body 42, and a bolt insertion hole 46 that penetrates the vertical portion 45 of the joining metal piece 44 is also provided.
On the other hand, the horizontal portion 47 of the metal joint 44 is provided with a bolt insertion hole 48 that penetrates the horizontal portion 47. Returning to FIG.
The bracket 41 has a bolt 49 inserted through the bolt insertion hole 48.
Is fixed to the lower beam 4 by screwing it with a back nut 50 welded to the back surface of the lower beam 4. And the outer wall panel
10 is a nut in which the bolt 51 inserted into the bolt insertion hole 46 of the bracket 41 is embedded in the outer wall panel 10 with the lower end placed on the upper surface of the receiving portion 43 of the bracket 41 fixed to the lower beam 4. It is fixed to the lower beam 4 via the bracket 41 by being screwed onto the beam 52. At this time, between the back surface of the outer wall panel 10 and the side surface of the lower beam 4, in order to make the room breathable and to absorb the lateral bending of the outer wall panel 10, A gap is formed. The predetermined size G is generally set to about 5 mm, for example.

[0004]

[Problems to be Solved by the Invention] Such a bracket
In 41, when fixing to the lower beam 4, the worker needs to tighten the bolt 49 while securing a gap of a predetermined dimension G between the outer wall panel 10 and the lower beam 4, so the fixing work is delicate. However, there is a problem that the fixing to the lower beam 4 becomes complicated. Further, since the fixing of the bracket 41 to the lower beam 4 is performed by the single bolt 49, as shown in FIG. 6, the bracket 41 itself may rotate when the bolt 49 is tightened. However, also from this point, there is a problem that the work of fixing the lower beam 4 becomes complicated.

It is an object of the present invention to provide a mounting bracket for an outer wall panel which facilitates fixing work.

[0006]

SUMMARY OF THE INVENTION The present invention is an outer wall panel mounting bracket for mounting an outer wall panel forming an outer wall of a building unit to a lower beam of the building unit, the bracket being in contact with a side surface of the lower beam. It is characterized in that a protrusion is provided. In the above, it is preferable that the protrusion is formed by partially extruding a member forming the bracket. Further, it is preferable that the protrusions are provided at four corners of a portion of the bracket that overlaps with the lower beam. Further, the bracket is
It is preferable that the metal plate is integrally formed by bending.

[0007]

According to the present invention as described above, the rear surface of the outer wall panel and the side surface of the lower beam do not need to worry that the protrusion provided on the bracket abuts the side surface of the lower beam and the operator secures a gap of a predetermined size. Since a gap having a predetermined size is automatically secured between the and, the fixing work with bolts becomes easy. Further, if the protrusions are provided at the four corners of the portion that overlaps the lower beam of the bracket, the bracket itself will not rotate during bolt tightening work, etc., and the fixing work can be performed more easily. The purpose is achieved.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. In the following description, the same members as those already described are designated by the same reference numerals, and the description thereof will be omitted or simplified. 1 and 2 show a bracket 20 according to this embodiment. Bracket 20 is an exterior wall panel 10
Is attached to the lower beam 4, and is formed by bending a metal plate material. That is, the bracket 20 has a receiving portion 21 formed by horizontally bending the lower end portion.
And a horizontal extending portion 22 formed by punching out an intermediate portion and bending it on the side opposite to the receiving portion 21. The trace of the horizontal extension 22 punched out is the opening 22A. Above the horizontal extension portion 22, a bolt insertion hole 23 that penetrates the upper end portion of the bracket 20 is provided. On the other hand, the horizontal extension portion 22 is provided with a bolt insertion hole 24 that penetrates the horizontal extension portion 22. Here, the bracket 20 is fixed to the lower beam 4 by screwing the bolt 49 inserted into the bolt insertion hole 24 with the back nut 50 welded to the back surface of the lower beam 4. . And the outer wall panel 10 is
With the lower end placed on the upper surface of the receiving portion 21 of the bracket 20 fixed to the lower beam 4, the bolt 51 inserted in the bolt insertion hole 23 of the bracket 20 is screwed into the nut 52 in the outer wall panel 10. As a result, it is fixed to the lower beam 4 via the bracket 20.

On both sides of the lower end portion of the bracket 20, rib-shaped projections 25 extending in the vertical direction are provided. These protrusions 25 come into contact with the side surface of the lower beam 4, are formed by a beading process for partially extruding the bracket 20, and have a predetermined height dimension H. on the other hand,
Protrusions 26 formed in a spherical shape are provided on both sides of the opening 22A of the bracket 20. These protrusions 26 are the protrusions 25
Similarly to the above, the abutment is made on the side surface of the lower beam 4, is formed by a beading process for partially extruding the bracket 20, and has the same predetermined height dimension H as the protrusion 25. Here, the protrusions 25 and 26 are arranged at the four corners of the portion overlapping the lower beam 4 of the bracket 20 (see FIG. 1). Also,
By fixing the outer wall panel 10 to the bracket 20 fixed to the lower beam 4, the projections 25 and 26 come into contact with the side surface of the lower beam 4,
Predetermined dimension G between the back surface of the outer wall panel 10 and the side surface of the lower beam 4.
The gap is automatically secured.

According to the above-described embodiment, the following effects can be obtained. In other words, since the bracket 20 for attaching the outer wall panel 10 to the lower beam 4 is provided with the protrusions 25 and 26 that come into contact with the side surface of the lower beam 4, the protrusion is provided even if the worker does not have to be aware of securing a gap. 25 and 26 serve as spacers, and a gap having a predetermined dimension G is automatically secured between the back surface of the outer wall panel 10 and the side surface of the lower beam 4, and the fixing work by the bracket 20 can be facilitated.

Further, the protrusions 25 and 26 are provided at the four corners of the portion overlapping the lower beam 4 of the bracket 20 so that the bracket 20 itself does not rotate when the bolt 49 for fixing the bracket 20 is tightened. The work of fixing the bracket 20 can be further facilitated.

Furthermore, since the bracket 20 is integrally formed by bending a metal plate material, the conventional bracket 41
Unlike the above, there are no welding points, welding work is unnecessary, and the production can be performed easily.

Further, since the members constituting the bracket 20 are partially extruded to form the protrusions 25 and 26, the bracket 20
Protrusions 25 and 26 are formed at the same time when bending 20
From this point as well, the manufacture can be easily performed.

Although the present invention has been described with reference to the preferred embodiment, the present invention is not limited to this embodiment, and various improvements and design changes can be made without departing from the gist of the present invention. It is possible. For example, the protrusions of the bracket are not limited to the protrusions 25 and 26 provided at the four corners of the portion that overlaps the lower beam 4 of the bracket 20, and a pair of rib-shaped protrusions that extend long along both edges of the bracket may be provided. Alternatively, it may be a rib-shaped projection provided in the middle portion of the bracket and intersecting in an X-shape, or a “d-shaped” rib-shaped projection.

Further, the method of processing the protrusion is not limited to beading which partially pushes out the bracket, and the method shown in FIG.
Like the horizontal extension portion 22 of the bracket 20 shown in FIG. 2, it may be punched and bent, and a plastic protrusion may be attached to the bracket.
