Description

[Detailed explanation of the invention] [Technical field] This invention uses horizontal members such as beams, girders, etc. as columns,
This invention relates to a jig for attaching horizontal members used when attaching them to building structures such as beams and walls.

[Background technology]

Conventionally, when attaching beams to columns, multiple workers manually supported the beams, or the beams were suspended using a crane, and another worker bolted the beams to the columns.
For this reason, the work of installing the beams was very time consuming. Moreover, because the beams were supported by hand or suspended by a crane, there was a risk that the beams would fall.

[Purpose of invention]

The purpose of this invention is to provide a jig for installing horizontal members that allows the work of installing horizontal members to be carried out safely and easily.

[Disclosure of invention]

The horizontal frame installation jig of this invention has a pin that is inserted into the main body from the bolt insertion hole of the horizontal frame member to a screw hole in the building structure to temporarily fix the horizontal frame member to the building structure. The main body is equipped with a magnet that attracts the frame material.

According to the configuration of this invention, there are the following effects.
That is, by inserting the pins into the screw holes of the building structure from the bolt insertion holes of the horizontal members, the horizontal members can be temporarily fixed to the building structure without falling.
Therefore, when attaching the horizontal members to the building structure, the worker does not have to support the horizontal members by hand or suspend them using a crane, making the installation work easier. Work can be done safely without worrying about objects falling.

Embodiment An embodiment of this invention will be described based on FIGS. 1 to 7. 1 to 3 are a perspective view, a side view, and an exploded perspective view of a jig for attaching a horizontal member. In the figure, 10 is a plate-shaped main body, and three screw holes 12, 14, and 20 are bored in the main body 10. Pins 16 and 18 are screwed into the screw holes 12 and 14 from one side of the main body 10, respectively. The outer diameters of the pins 16 and 18 decrease in two steps from the end where the main body 10 is attached, and the outer circumferential surface tapers toward the tip. Further, a handle eye bolt 22 is screwed and attached to the screw hole 20 from the other surface of the main body 10. Further, plate-shaped magnets 24 and 26 are fixed to both edges of the surface of the main body 10 to which the pins 16 and 18 are screwed, and a magnet 28 is also fixed to the lower end surface of the main body 10.

A procedure for temporarily fixing a horizontal member to a building structure using the thus formed horizontal member attachment jig will be explained based on FIGS. 4 to 7. Fourth
In the figure, 30 is a building structure consisting of square pipe-shaped columns. 32 is a horizontal member made of a beam, and is made of I-beam steel. The horizontal member 32 has an end plate 34 on the end surface, and the end plate 34 has a screw hole 42 bored in the side surface of the building structure 30 (see FIG. 6).
Bolt insertion holes 36, 38, 4 are located opposite the
0, 44, and 46 are cleared. In addition, imaginary lines A, B, surrounding each bolt insertion hole 36, 38, 40,
C indicates a location where the horizontal member attachment jig can be used.

Figures 5 and 6 show usable location C (4th
(See figure) shows an example of how to use the horizontal member mounting jig. The pins 16 and 18 of the horizontal frame member attachment jig are inserted through the bolt insertion holes 40 of the end plate 34 of the horizontal frame member 32 and into the screw holes 42 of the building structure 30, respectively. Then, the large diameter portions 18a of the pins 16, 18 are inserted into the bolt insertion holes 40, and the small diameter portions 18b are inserted into the screw holes 4.
2 is inserted. Furthermore, the magnets 24 and 26 are attracted to the end plate 34, and the horizontal member 32 is temporarily fixed to the building structure 30.

In this way, the horizontal member 3 is installed using the horizontal member installation jig.
2 to the building structure 30, the bolt insertion holes 36, 38, 4 of the end plate 34 of the horizontal member 32 are temporarily fixed to the building structure 30.
4, 46 and insert the bolt 48 into the building structure 30.
Fasten it to the screw hole (not shown) drilled in the hole. Furthermore, remove the horizontal member mounting jig and insert the bolt insertion hole 40.
Fasten the bolts to the screw holes 42 from the horizontal member 32.
is fixed to the building structure 30. The magnets 28 of the horizontal frame attachment jig are used to attract the horizontal frame attachment jig so that it does not fall off the horizontal frame when the jig is temporarily placed on the horizontal frame.

According to the jig for attaching horizontal members configured in this way, the pins 16 and 18 are inserted through the bolt insertion holes 40 of the end plates 34 of the horizontal members 32 into the screw holes 42 of the building structure 30.
The horizontal member 32 can be temporarily fixed to the building structure 30 by inserting the horizontal member 32 into the building structure 30. Therefore, when temporarily fixing the horizontal members 32 to the building structure 30, if both ends of the horizontal members 32 are temporarily fixed to the building structure 30, the worker can support the horizontal members 32 by hand. The work of attaching the horizontal member 32 can be easily performed, since the trouble of holding the horizontal member 32 by hanging it with a crane can be eliminated.

Further, since the two pins 16 and 18 are inserted through the bolt insertion hole 40 of the end plate 34 into the screw hole 42 of the building structure 30, the horizontal member 32 does not rotate. Moreover, the outer diameter of the pins 16 and 18 changes in two steps, and the magnets 24 and 26, which are inserted into the bolt insertion hole 40 and the screw hole 42 and fixed to the main body 10, are attracted to the end plate 34, so that the pin 16 , 18 do not come off from the bolt insertion holes 40 and screw holes 42, and the horizontal members 32 do not fall from the building structure 30. In this way, the horizontal members 32 can be reliably temporarily fixed to the building structure 30 without rotating or falling, and the installation work of the horizontal members 32 can be performed safely.

Furthermore, since the effort of supporting the horizontal members 32 can be saved, the installation work of the horizontal members 32 can be carried out quickly.

Moreover, since the horizontal member 32 is temporarily fixed at the mounting position using the horizontal member mounting jig, the horizontal member 32 can be reliably fixed without variations in the mounting position.

Furthermore, the main body 10 and pin 1 of the horizontal member installation jig
Since 6 and 18 are prefabricated, the length of the pins can be changed depending on the wall thickness of the horizontal members or building structure, or the pins can be replaced with pins of a diameter that matches the size of the bolt holes. can.

Note that the horizontal frame members 32 may be temporarily fixed to the building structure 30 using a jig for attaching the horizontal frame members at the usable positions A and B.

In addition, the jig for installing the horizontal members is magnets 24, 26, 2.
8 may be used. In this case, the pins 16 and 18 are simply inserted through the bolt insertion holes of the horizontal member 32 into the screw holes of the building structure 30, but since the load of the horizontal member 32 is applied to the pins 16 and 18, the pins 16 and 18 are It never goes away. Further, the main body 10 of the horizontal member attachment jig may be formed of a magnet.

Furthermore, the number of pins 16 and 18 may be one or more than two. When the horizontal member attachment jig has one pin, a plurality of horizontal member attachment jigs can be used to prevent the horizontal member from rotating. Note that if there is no concern that the horizontal member will rotate, one horizontal member mounting jig may be sufficient.

[Effect of idea]

The horizontal member mounting jig of this invention provides the following effects.

By inserting the pin screwed into the main body from the bolt insertion hole of the horizontal member into the screw hole of the building structure, the horizontal member can be temporarily fixed to the building structure without falling. In addition, by preparing pins of various shapes and replacing them, it is possible to accommodate changes in the size of the insertion hole in the horizontal member or the diameter of the screw hole in the building structure. Therefore, the trouble of supporting the horizontal members when fixing them to the building structure is eliminated, the installation work is easy, and there is no fear that the horizontal members will fall. Because it sticks to the material, it will not fall off accidentally and you can work safely.
