Description

[Detailed description of the invention] [Field of industrial application] The present invention is a positioning method for easily and quickly fixing a trapezoidal-shaped receiving fitting having a tip bolt fixed to the top piece in a predetermined position on a structural member. This invention relates to a jig for mounting a receiving metal fitting that can be installed accurately and quickly.

[Conventional technology and its problems]

Conventionally, a bracket is fixed onto a structural material such as a main building, and building boards such as roof boards or wall boards are attached to the bracket to form a roof. Adequate attention was paid to adhesion.

Even if there is a small error in the mounting position (welding position) of the bracket, if this happens continuously, the roofing pitch of the building boards will be distorted, and adjacent parts will not be able to be connected watertight. There were inconveniences such as roof failure, or in extreme cases, the roof could not be constructed.

For this reason, if the mounting work of the receiving bracket is done too carefully, it will take time unnecessarily and the efficiency of construction will be reduced.

Furthermore, even if an assignment pitch line is marked on a structural material such as a main building, it is quite troublesome to accurately set the shaft center of the tip bolt of a receiving bracket with a trapezoidal chevron cross section at the location of the assignment pitch line. It was hot.

[Means to solve the problem]

Therefore, the inventor worked diligently to solve the above problem.
As a result of repeated research, we developed the present invention by installing a head in the center of the top of a gate-shaped fixed base so that it can rotate freely on a horizontal plane, and attaching a substantially horizontal main rod to the head so that it cannot move in the axial direction. By fixing the sword point rod in a hanging manner on both sides of this main rod, and creating a positioning hole with a downward opening in the center of the top of the gate-shaped fixing base, the sword point can be fixed. It is possible to easily and quickly position the receiving fitting with the bolt fixed to the top piece to accurately fix it in a predetermined position on the structural material, and it is also possible to fix (weld) the receiving fitting well without any problems. This solves the problem with metal holders.

is fixed thereto, and horizontal bottom portions 5b, 5b facing outward are integrally formed at both lower ends of the mountain-shaped portion 5a (see FIG. 4).

[Effect]

As an example of the use of the jig for the receiving fitting of the present invention, the receiving fitting 5
The case of determining the welding point position etc. when attaching to the structural member 6 will be explained.

While inserting and fixing the tip bolt 5c of the receiving fitting 5 into the positioning hole 1c of the receiving fitting mounting jig, the entire receiving fitting 5 is set to be substantially perpendicular to the gate-shaped fixing base 4.

Next, in the above-mentioned state, the receiving fitting mounting jig and the receiving fitting are placed at appropriate positions on the structural member 6, which has already been marked with the marking lines at the predetermined pitches. At this time, the structural member 6 is sandwiched between the legs 4b, 4b of the gate-shaped fixing base 4, and the gate-shaped fixing base 4 is pushed into the structural member 6 until the stoppers 4d, 4d abut against the upper edge of the structural member 6. Then, the head 1 is rotated so that the tip of the tip rod 3 coincides with the pitch line (see FIG. 4). Rotate the head 1 and the shaft 2 at the point where the pitch line position and the tip of the sword tip rod 3 match, and in this state, hold the bottom 5b of the holder 5.
Weld the periphery (see Figure 5).

[Effect of idea]

In the present invention, a head 1 is provided at the center of the top 4a of the gate-shaped fixed base 4 so as to be freely rotatable on a horizontal plane, and a substantially horizontal main rod 2 is attached to the head 1 so as to be immovable in the axial direction. The tip rods 3, 3 are fixed to both sides of the main rod 1 in a hanging manner, and a positioning hole 1c with a downward opening is provided in the center of the top 4a of the gate-shaped fixing base 4. Firstly, by using the bracket 5 as a tool, it is possible to easily and quickly position the bracket 5 to which the tip bolt 5c is fixed at the top to accurately fix it in a predetermined position on the structural member 6. It has the effect of being able to fix (weld) the parts without any problems.

To explain these effects in detail, first,
The head 1 is rotatably provided at the center of the top 4a of the gate-shaped fixed base 4, and a positioning hole 1c with an opening at the bottom is provided at the center of the bottom surface of the top 4a. The distance L between the positioning hole 1c and the axis of the tip rod 3 is always constant.

For this reason, the tip bolt 5c of the bracket 5 with the tip bolt 5c is inserted into the positioning hole 1 of the present invention.
By aligning the pitch line of the structural member 6 of the tip rod 3 with the pitch line of the structural member 6, the position of the pitch line + distance L becomes the position of the tip rod 3, and the receiving bracket with the tip bolt 5c 5 can be set at a predetermined position on the structural member 6 extremely easily and quickly.

Regarding this kind of setting effect, normally,
The socket 5 must be placed so that the axis of the bolt 5c coincides with a predetermined position on the structural member 6, but the bolt 5c of the socket 5 must be fixed to the top of the chevron-shaped portion 5a. Therefore, it is extremely difficult to judge whether the predetermined position of the structural member 6 and the axis of the tip bolt 5c are aligned. For this reason, in the present invention, the axis of the tip bolt 5c of the tip rod 5 can also be adjusted by simply aligning the tip rod 3 without aligning the axis of the tip bolt 5c with the pitch line. It has the advantage that it can be set at an accurate position with a distance of +L.

In addition, in the present invention, the tip bolt 5c of the receiving bracket 5 with the tip bolt 5c is inserted into the positioning hole 1c of the present invention.
After inserting and supporting the tip rod 3 into the pitch line of the structural member 6, rotate the head 1 to move the tip rod 3 away from the bottom 5b of the receiving fitting 5. I can do it. That is, it is necessary to fix (weld) the bracket 5 at the desired position while fixing the bracket 5. For this reason, while holding the position of the bracket 5, the main rod 2 of the bracket 5 must be fixed. Rotate to move the tip rod 3 from the position of the bracket 5 (see the chain line in Figure 1), and while keeping the tip rod 3 out of the way, weld the bottom 5b of the bracket 5. The receiving metal fitting 5 is fixed to the structural member 6.

In this way, the tip rods 3, 3 do not get in the way when the main rod 2 is rotated, and the mounting (welding) of the receiving metal fitting 5 is facilitated.

In addition, in the case where the bracket 5 is fixed continuously on the structural material 6, if the space between the tip rods 3 and 3 is set to the allocation pitch of the bracket 5, accurate marking can be done immediately. It is something that can be worked on.
