Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a shutter bracket, and more specifically, even if there is an error in the position of the mounting bolt that tightens and fixes the mounting piece provided on the bracket, it will remain in the specified mounting position. This invention relates to a mounting structure for a shutter bracket that can be adjusted and fixed securely.

Generally, the bracket that supports the take-up shaft of the shutter that opens and closes the opening is constructed by inserting a mounting bolt provided on the building frame side above the opening into the mounting hole of the mounting piece provided on the bracket, and then tightening the tightening nut. However, when installing the mounting bolts, since there are reinforcing bars and aggregates in the concrete of the building frame, it is recommended to use a drill to drill holes for the mounting bolts in the correct locations. Unfortunately, if the installation position of the mounting bolt is incorrect, one side of the installed shutter will fall down, and the shutter case and the seat plate at the bottom of the rolled-up shutter curtain will not be flush with each other, making it difficult to open and close. There are inconveniences such as things not going smoothly. For this reason, in the past, the mounting holes in the mounting pieces were re-drilled on site to adjust the mounting position, but this had the disadvantage that correcting the mounting holes was troublesome and the work of mounting the bracket was inefficient. Therefore, it has been proposed to form the mounting hole of the mounting piece into a long hole so that the mounting position of the bracket can be adjusted up and down. However, it is not supported by mounting bolts, but is simply pressed and fixed to the building frame by the tightening force of the tightening nut, resulting in a disadvantage that the mounting strength is weakened.

The present invention was devised in view of the above-mentioned circumstances, and the mounting hole of the mounting piece is formed to have a larger diameter than the diameter of the mounting bolt so that the mounting position of the bracket can be adjusted. A fixing plate is interposed between the piece and the tightening nut, and the fixing plate is inserted into the mounting bolt in a tight-fitting manner, and the fixing plate is tightened and fixed at the adjusted mounting position with the tightening nut. In addition, since it is fixed to the mounting piece by welding, even though the large hole is used to adjust the mounting position of the shutter bracket, the fixing work after adjustment can be performed only by welding, and the mounting strength is ensured. The object of the present invention is to provide a mounting structure for a shutter bracket.

To explain the structure of the present invention with reference to an embodiment shown in the drawings, 1 is a shutter installed in an opening of a building, and a shutter curtain 2 wound around a winding shaft is installed on the left and right sides of the opening. It opens and closes the opening by moving up and down while being guided by a guide rail 3 erected. Reference numeral 4 denotes a shutter case of the shutter curtain 2, and as shown in FIGS. 2 to 4, it includes a mounting piece 6 of a bracket 5 supporting the winding shaft, a fixing plate 7, a washer 8, and a tightening nut. 9, it is attached and fixed to a mounting bolt 10 planted in the building frame A above the opening. That is, an angle-shaped mounting piece 6 is vertically welded and fixed to the bracket 5 that supports the winding shaft, and the mounting piece 6 has a diameter larger than the diameter of the mounting bolt 10 at a position corresponding to the mounting bolt 10. Also, a large diameter mounting hole 6a is bored. Further, the fixing plate 7 is a plate having an insertion hole 7a formed approximately in the center thereof, into which a mounting bolt 10 is inserted in a tight-fitting manner. It is interposed in a pinch-like manner between the locking nut 9 and the locking nut 9, and is tightened and fixed to the building frame A by the washer 8 and the tightening nut 9. 11 is a bearing portion formed on the bracket 5;
2 is a seat board.

In the above configuration, shutter 1
To install the bolt, first use a drill or the like to drill a bolt hole at a predetermined position above the opening of the building frame A, and then drive a known anchor bolt, etc. whose end expands when struck, into the bolt hole to secure the mounting bolt. 10 will be erected. Next, the mounting bolt 10 is inserted into the mounting hole 6a of the mounting piece 6 provided on the bracket 5, and the fixing plate 7 is locked by inserting the mounting bolt 10 through the insertion hole 7a. Tighten and fix.

At this time, even if the mounting bolt 10 is not correctly installed in the predetermined position due to interference with reinforcing bars or aggregates in the concrete, the mounting hole 6a of the mounting piece 6
Since it is formed to have a larger diameter than the diameter of the mounting bolt 10, it can be accurately adjusted to a predetermined position by moving the mounting piece 6 while slightly loosening the tightening nut 9. Then, tighten the tightening nut 9 at the adjusted position. Then, by welding the peripheral edge of the fixing plate 7 to the mounting piece 6 and fixing it integrally, the fixing plate 7 has its insertion hole 7a.
Since it is inserted into the mounting bolt 10 in a tight fit, even if the mounting hole 6a of the mounting piece 6 has a larger diameter than the diameter of the mounting bolt 10, the fixing plate 7 integrally fixed to the mounting piece 6 will not Since it is reliably supported by the mounting bolt 10, the mounting piece 6 does not move relative to the mounting bolt 10, and the bracket 5 can be accurately and firmly fixed in a predetermined position. Then, if the winding shaft of the shutter curtain 2 is pivotally supported on the bearing part 11 of the bracket 5, one side of the attached shutter 1 will be lowered and the shutter case 2 will be lowered.
There is no problem that the seat plate 12 is not flush with the seat plate 12, and the shutter 1 can be opened and closed smoothly.

In short, the present invention involves planting mounting bolts on the building frame side above the opening, and inserting and tightening the mounting bolts through the mounting holes of the mounting pieces provided on the bracket that supports the winding shaft. In the shutter bracket mounting structure in which the shutter bracket is tightened and fixed with a mounting nut, the mounting hole is formed to have a diameter larger than the diameter of the mounting bolt to enable adjustment of the mounting position of the bracket, and the mounting hole and the mounting piece are Tightening nut 9
A fixing plate is interposed between the mounting bolt and the fixing plate, which is inserted into the mounting bolt in a tight-fitting manner. Since the bracket is fixed by welding, the mounting hole, which is larger than the diameter of the mounting bolt, does not allow for free adjustment of the mounting position of the bracket, and the fixing plate is tightly fitted to the mounting bolt. After adjusting the position, simply welding the fixing plate to the mounting piece will ensure that the fixing plate fixed to the mounting piece is supported by the mounting bolt, and the mounting piece will be attached to the mounting bolt. It does not move and allows the bracket to be accurately and firmly fixed in place.
In the subsequent process, the winding shaft and shutter curtain can also be accurately attached, and smooth opening and closing can be expected, which provides extremely useful practical effects.
