Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an attachment device for attaching a bar for attaching a switchbox to the back side of a lightweight type steel.

(Prior Art) Conventionally, in order to attach a bar for attaching a switch box, such as a square bar, to a lightweight steel section, a special tool was used on the back side of the lightweight steel section 21 facing the opening, as shown in Fig. 6. A square hole 22 was bored through the square hole 22, and both ends of a square bar 23 were inserted through the square hole 22.

Therefore, it is necessary to drill square holes 22 in the lightweight type steel 21 one by one using a special tool, and the drilling work of the square holes 22 is extremely troublesome. If only the square bar 23 is inserted, the square bar 23 will wobble due to the gap between the two, so there is a problem in that some means must be taken to prevent this wobbling.

(Problems to be Solved by the Invention) In view of the above-mentioned problems, the present invention was devised for the purpose of easily and firmly attaching a bar to the back surface of a lightweight type steel without drilling.

(Means for solving the problem) In the present invention, a cylindrical fixing body with a bar insertion hole for sandwiching and fixing the end of the bar from the entire circumference by elastic deformation is integrated into the seat plate. In this embodiment, a fixture having a configuration is formed, and this fixture is fixed to the back side of the lightweight type steel via a fixing means.

(Embodiment) An embodiment of the present invention is shown in FIGS. 1 to 5, and the fixture A will be explained first.

The fixture A is made of resin, and as shown in FIGS. 3 and 4, it is located at the center of the rectangular seat plate 1 in the height direction, and is offset to one end from the center in the horizontal direction. A fixing body 3 for sandwiching and fixing the end of the square bar 2 by elastic deformation is integrally provided at a position.

The fixed body 3 provided integrally with the fixture A includes a square tube portion 4 into which the end of the square bar 2 is inserted, and a deformation acting portion 5 for elastically deforming a part of the square tube portion 4. Consists of. The square tube part 4 consists of a fixed part 4a that is provided integrally with the seat plate 1, and a deformable part 4b that is elastically deformable because it is not fixed to the seat plate 1 through a gap b. The deforming portion 5 includes a fixed portion 5a integrally provided on the seat plate 1 and a deforming portion 4 of the rectangular tube portion 4.
The movable part 5b is connected to the movable part 5b, and the two face each other with a gap c therebetween. A nut insertion groove 7 for inserting a tightening nut 6 is provided in the fixed part 5a of the deformation acting part 5 and is open on the upper surface, and a bolt for inserting a tightening bolt 8 is provided in the movable part 5b. An insertion groove 9 is also provided with an opening on the top surface.

Therefore, the end of the square bar 2 is inserted into the square hole 10 provided in the square tube part 4, and the tightening bolt 8 inserted into the bolt insertion groove 9 and the tightening nut 6 inserted into the nut insertion groove 7 are inserted. When screwed together and tightened, only the deformable portion 4b of the square tube portion 4 is elastically deformed and slightly bent in the direction of arrow Q (Fig. 3), with a gap c being sandwiched between the ends of the square bar 2. is fixed by being sandwiched by the rectangular tube portion 4 from the entire circumference.

In addition, at the upper and lower ends of the seat plate 1, when fixing the fixture A to the back surface P1 of the lightweight steel P through the steel plate screws 11, there are provided screws for adjusting the horizontal fixing position of the fixture A with respect to the lightweight steel P. A long iron plate screw insertion hole 12 is provided so that the metal plate screw can be inserted.

Then, attach the fixture A to the back side P1 of the lightweight steel P.
To fix this, place the seat plate 1 of the fixture A in close contact with this rear part P1, insert the tip of the iron plate screw 11 into the iron plate screw insertion elongated hole 12 in this state, and tighten the iron plate screw 11 with an electric screwdriver. When the steel plate screw 11 is rotated while being pressed more strongly (not shown), the steel plate screw 11 is screwed into the back part P1 of the lightweight steel P.
A fixture A is fixed to the back surface P1 of the machine.

Next, as shown in FIG. 5, a lightweight steel P with another square bar fixture B fixed to the opening is erected adjacent to the lightweight steel P with the fixture A fixed to the back surface P1. The square bar 2 is inserted into the square hole (not shown) provided in the square bar fixture B of this lightweight type steel P, and pushed in until one end of the square bar 2 comes into contact with the inside of the back surface of the square bar 2. Then, pull out this square bar 2 in the opposite direction, insert the other end into the square hole 10 provided in the square tube part 4 of the fixture A, and insert the tightening bolt 8 inserted into the bolt insertion groove 9. When the tightening nut 6 inserted into the nut insertion groove 7 is screwed together and tightened, only the deformed part 4b of the square tube part 4 is elastically deformed and slightly bent in the direction of arrow Q, narrowing the gap c. , the other end of the square bar 2 is fixed by being sandwiched by the square tube part 4 from the entire circumference.

Then, the switch box S is attached to a predetermined position of the square bar 2 attached to the lightweight type steel P via the fixture 13.

In FIG. 5, W indicates a wall material such as a stone board placed outside the lightweight steel P.

Further, in the above embodiment, a case has been described in which the end of the square bar 2 is fixed, but by replacing the square cylindrical part 4 with a cylindrical part, the end of a round bar having a circular cross section can be fixed. Furthermore, the fixing means for fixing the fixture to the back surface of the lightweight type steel is not limited to iron plate screws as in the above embodiments, but may be, for example, a strong adhesive or the like.

(Effects) The present invention utilizes a mounting device in which a cylindrical fixing body with a bar insertion hole that clamps and fixes the end of the bar from the entire circumference by elastic deformation is integrally provided on the seat plate. This fixture is fixed to the back side of a lightweight type steel via a fixing means, and by elastically deforming a part of the fixing body, a bar inserted through a bar insertion hole provided in the fixing body is inserted and fixed. Therefore, the bar can be easily and firmly attached without drilling a bar insertion hole in the back surface of the lightweight type steel.

In particular, by using iron plate screws as a fixing means and providing long iron plate screw insertion holes in the upper and lower ends of the seat plate in the horizontal direction, the fixing position of the fixture in the horizontal direction with respect to the lightweight steel can be adjusted. can be freely adjusted according to the size of the switchbox attached to the bar.
