Description

[Detailed explanation of the invention] This invention is based on the following method:
This relates to a jig for supporting and mounting a shutter bracket.

When installing a shutter in a building opening, it is first necessary to fix a bracket that supports the shutter's take-up shaft in a predetermined position above the building opening, but conventionally, to fix this bracket, Mark out the lower end position and vertical position of the side surface of the bracket in advance on the mounting surface above the opening according to the mounting specifications, and while supporting the bracket by aligning it with the marking, insert the mounting hole of the mounting angle provided on the bracket. The bracket is quite heavy and the mounting position is above the opening, so I used one hand to align the bracket with the marked position and hold it vertically to support it. However, it is not easy to drive a nail into the fixing hole of the mounting angle with the other hand, and special skill is required to accurately mount the bracket.

In addition, to install the intermediate bracket, nails are driven into the mounting positions of the left and right brackets, a separately prepared water thread is stretched between the opposing nails, and the position is determined using this water thread as a reference. Since the length is not necessarily constant, the stretched water string will not be parallel to the beam surface of the building, and the distance between the bracket mounting surface and the water string will vary each time, so it is necessary to accurately mark the mounting position of the bracket. It has the disadvantage that it is difficult to take it out.

The present invention was devised in view of the above-mentioned circumstances, and is fixed at a predetermined position on the building side marked vertically and horizontally for positioning, and is installed while supporting the bracket of the shutter. This jig is formed into an L-shaped cross section by a vertical piece fixed to the building side and a horizontal piece supporting the bracket, and the bracket supporting surface of the horizontal piece has a , by providing lines to determine the mounting position of the bracket in the left and right direction, the bracket can be supported on the top surface of the jig fixed by aligning the horizontal piece with the bottom mounting position of the bracket, which requires special skill. In addition to being able to accurately mount the bracket at the marked position without the need for a bracket, it is also possible to easily mark and mount the intermediate bracket's exact mounting position based on the fixed left and right mounting jigs. The present invention aims to provide a bracket mounting jig.

To explain the structure of the present invention with reference to an embodiment shown in the drawings, 1 is a nail that is inserted through a mounting hole 3a of a mounting angle 3 into a predetermined position on the upper side of pillars 2 and 2, which are erected on both sides of an opening. A bracket 4 is attached to a beam 5 approximately in the middle of the pillars 2, 2, etc.
An intermediate bracket is attached and fixed in the same manner as described above to the bridge 7 that connects the lintel 6 and the lintel 6, and the winding shaft of the shutter (not shown) is installed between the bearings 1a and 4a of the opposing brackets 1 and 4. It's getting old.

Reference numeral 8 denotes a jig main body made of a thin iron plate, and the jig main body 8 is bent into an L-shape having a vertical piece 9 and a horizontal piece 10. A nail hole 11 for fixing the jig main body 8 is bored in the jig. The jig main body 8 is formed to be small and lightweight to the extent that it can place and support the proximal end of the bracket 1 when it is fixed to the pillar 2.

Reference numeral 12 denotes a pair of locking protrusions projecting from the vertical piece 9. The tip of the locking protrusion 12 is bent in the vertical direction to form a hook shape. To,
It is designed so that the thread can be wound and its ends fixed.

On the surface of the horizontal piece 10, a shallow positioning groove 13 into which the water line slightly sinks is formed parallel to the vertical piece 9, and on the front and back sides thereof, there are grooves 13 perpendicular to the vertical piece 9. A plurality of line markings 14 are provided in parallel to determine the mounting position of the bracket 1 in the left and right direction.
14a is its center line, 15 is a shutter guide, 16 is a double-sided double guide, 17 is an auxiliary thread positioning groove, 18 is a see-through window for collimating the ink on the building side on the back, and 19 is a vertical piece. This is the vertical reference line provided at 9.

In the above configuration, in order to install the bracket 1 on the pillar 2, first mark the horizontal line on the pillars 2, 2 on both sides of the opening that indicates the mounting bottom surface position of the bracket 1 according to the installation specifications, and the mounting position of the bracket 1. Mark out a vertical line to indicate the side position. Next, align the top surface of the horizontal piece 10 of the mounting jig 8 with the horizontal line,
Then, while holding the center line 14a of the line markings 14 provided on the horizontal piece 10 or the proximal end of the line marking 14, which is the reference line 14 appropriately selected depending on the situation, coincides with the vertical line, insert the nail hole. The jig main body 8 is fixed to the pillar 2 by driving a small nail into the hole 11. At this time,
The jig main body 8 is formed to be small and lightweight enough to place and support the proximal end of the bracket 1, so that it can be easily held with one hand while driving a nail with the other hand. It can be fixed at precisely marked positions. After fixing the jig body 8 to the left and right pillars 2, 2, fix one end of the water string to the locking protrusion 12 of one jig body 8, and wrap the other end around the other jig body 8. This makes it easy to tension and fix the water string, and since the horizontal piece 10 of the jig main body 8 is recessed with the water string positioning groove 13, the water string can be easily fixed with tension on the beam 5 (lintel 6) surface. It can be stretched parallel and horizontally, and the distance between the mounting surface of the intermediate bracket 4 or 7 and the water thread is constant, so the intermediate bracket 4 can be installed at the following position based on this water thread: You can accurately mark out and fix it by following the steps. First, set a water thread in line with the auxiliary water thread positioning groove 17 on the reference side of the jig main body 8, apply horizontal ink on the lintel 6 surface along the water thread, and then adjust the position of the intermediate bracket 4 from side to side. Accurately determine the mounting position of the intermediate bracket 4 by measuring along the water line from the mounting position of one of the brackets 1 and using a plumb bob or the like to mark out a vertical line on the 7th surface, etc. Can be done. When fixing the jig body 8 to the mounting position of the intermediate bracket 4, there is usually no part like a pillar to fix the vertical piece 9 of the jig body 8 downward, so the jig body 8 is turned upside down. Then, align the horizontal piece 10 with the vertical line marked out through the line markings 14 on the back side of the horizontal piece 10, and attach and fix it with nails across the bridge 7 and the lintel 6.

Next, place the bracket 1 on the fixed jig body 8.
, and fix it with a fixing tool such as a nail through the mounting hole 3a of the mounting angle 3 while aligning the side surface with the marked vertical line and aligning one side of the bottom surface with the line mark 14 on the horizontal piece 10. Bye. Even if the bracket 1 is heavy, it can be reliably supported by the jig main body 8, so the brackets 1 and 4 can be easily and accurately mounted without requiring special skill. If the building is made of steel, it is sufficient to mark out the position of the nail hole 11, drill the hole, and then fix it with a pin screw. After the brackets 1 and 4 are attached, the jig main body 8 is attached with small nails, so it can be easily removed and can be used repeatedly.

At this time, even if the water line stretched along the positioning groove 13 of the jig main body 8 is pressed down by the bracket 1 placed thereon, the water line sinks into the groove from the horizontal surface of the horizontal piece 10. Therefore, it will not be cut due to the weight of bracket 1. On the other hand, middle bracket 4
In this case, since the jig main body 8 is upside down, the depth of the positioning groove 13 becomes slightly higher, but the error is small. Furthermore, it is known that mounting the intermediate bracket 4 somewhat higher to provide a "bulk" will correct visual perception when the shutter case is finally completed. In addition, in buildings with wooden or light steel structures, if the lintel 6 has a slight lack of strength, the weight of the attached shutter may cause the lintel 6 to receive horizontal force at the lower end of the lintel 7 toward the indoor side. However, since the outer end side of the intermediate bracket 4 is lowered, it is desirable to install the intermediate bracket 4 at a middle height in order to correct this problem. In such a case, since the jig main body 8 is above the water line, the jig main body 8 can be installed as high as desired, and there is no reason to install the intermediate bracket 4 at a position lower than the water line. ,
The height error due to the positioning groove 13 of the jig main body 8 which is turned upside down is so small that it can be completely ignored.

Furthermore, the mounting position of the intermediate bracket can be easily and accurately marked out based on the water thread stretched between the left and right mounting jigs. The water string can be easily stretched by winding it around the locking protrusion, and the tensioning position of the water string can be selected in the front-back direction depending on the measurement of the mounting position and the installation of the bracket. .

In short, the present invention is a jig for fixing the shutter at a predetermined position on the building side marked vertically and horizontally for pre-positioning, and supporting the bracket of the shutter.
The jig is formed into an L-shaped cross section by a vertical piece that is fixed to the building side and a horizontal piece that supports the bracket, and the bracket supporting surface of the horizontal piece has a mounting position in the left and right direction of the bracket. Since there is a line marking that determines the
Can be installed easily. In addition, since the horizontal piece of the jig and the line markings are fixed in alignment with the horizontal and vertical lines that have been marked out, the bracket can be accurately positioned in both the left and right directions as well as in the lifting direction based on the line markings. The present invention has extremely useful practical effects, such as being able to be installed in a predetermined position without requiring any special skill.
