Description of the Related Art For example, as shown in FIG. 8, when constructing a building 50 such as a soundproof house which can be assembled and disassembled, as shown in FIG.
It is necessary to assemble and disassemble a panel member 52 which is a wall material covering the outside of the mold steel 51. However, the connection between the conventional H-shaped steel 51 and the panel member 52 is performed, for example, by connecting a connecting tool 53 having a step corresponding to the thickness of the web 51a of the H-shaped steel 51 as shown in FIG.
a, abutting against each inner surface of the panel member 52,
And the connecting tool 53 are integrally connected by a bolt 54 and a nut 55, and the projecting end of the tightening bolt 56 screwed to the connecting tool 53 is brought into contact with the inner surface of the web 51a. The protruding end of the H-shaped steel 51 damages the abutment surface of the web 51a, and causes a so-called razor motion (the eccentric motion state of the tightening bolt 56) at the protruding end of the tightening bolt 56. A state occurs in which the protruding end of 56 is rattled on the contact surface of the web 51a of the H-shaped steel 51, and the panel member 52 is moved. Therefore, the connecting tool 53 is fixed to the web 51a of the H-shaped steel 51. However, there is a problem that the connection between the H-shaped steel 51 and the panel member 52 is hindered. Further, when constructing the building 50 such as the soundproof house as described above, it is necessary to connect the ends of the H-shaped steel 51 as the structural steel material in series, but it is necessary to connect the ends of the conventional H-shaped steel 51 to each other. 10 and 11, the ends of the H-shaped steel members 51 abut against each other, and the webs 51a of both H-shaped steel members 51,
The connecting plates 61a, 61b are arranged so as to straddle the respective 51b, and these are connected using the bolts 62 and the nuts 63. The connecting plates 61c are also provided on both sides of the butted portion of the connecting pieces 51c of both the H-shaped steels 51. 61d are arranged and connected using bolts 64 and nuts 65. . As a result, the webs 51a of both H-section steels 51,
The connecting plate 61a is exposed to the outside of the web 51a.
There was a problem that it could not be arranged outside 1a. The object of the invention is to solve is therefore an object of the present invention is, Ken
The structural steel material of the structure and the panel member can be attached and detached with simple operation
And the two can be firmly connected to each other.
The ends of the steel bars are in a shape that does not hinder the installation of the panel members.
It is an object of the present invention to provide a connecting tool that can be connected in a state . According to the first aspect of the present invention,
A connecting tool for connecting a structural steel material of a building made of an H-section steel or an angle steel to a panel member attached to the outside of the structural steel material, wherein the structural steel member has a panel member-attached side wall. A steel member contact portion having a step corresponding to a thick portion and a panel member contact portion contacting the inner surface of the panel member contacting the structural steel material are provided on one end side, and bolts are inserted through the panel member contact portion side. A main body having an area, a steel material pressing tool having an end face facing a steel material contact portion of the main body, a bolted body attached to the other end side of the main body so as to face the steel material pressing tool, A second bolt that is screwed into the body and abuts the tip against the steel pressing tool, and presses the steel pressing tool into pressure contact with the structural steel; and screws the second bolt into the second bolt. Tighten to bolted body And a first bolt inserted into the bolt insertion area and screwed with a nut disposed on the panel member side to fix the panel member contact portion side of the main body to the panel member. is there. The operation of the present invention will be described below. When the structural steel material of the building and the panel member are connected by the connecting tool according to claim 1, the panel member is joined and arranged outside the structural steel material made of H-shaped steel or angle steel . The respective surfaces of the steel material contact portion are positioned on the inner surface and the end surface of the structural steel material, and the steel material pressing tool is brought into contact with the inner surface of the structural steel material, and the panel member contact portion is brought into contact with the inner surface of the panel member. Then, the first bolt inserted into the bolt insertion area of the main body is screwed with a nut arranged on the panel member side to fix the panel member contact portion side of the main body to the panel member. Also, as described above, the second bolt is screwed into the bolted body while the steel material abutting portion of the main body is brought into contact with the inner surface of the structural steel material while the steel material pressing tool is in contact with the inner surface of the structural steel material.
The tip of the second bolt is brought into contact with the steel pressing tool to press the steel pressing tool against the structural steel, and the nut is used to fasten the second bolt to the bolted body. As a result, the tip of the second bolt does not directly contact the structural steel material, and the steel material pressing tool comes into pressure contact with the structural steel material. The tip of the second bolt is used to contact the structural steel material. The structural steel material and the panel member can be firmly connected without damaging the contact surface and without so-called sliding motion (the state of eccentric motion of the second bolt) as in the conventional example described above. Also, loosen the nut,
With a simple operation of loosening the second bolt and turning the first bolt in reverse, the structural steel material and the panel member can be separated. Since the structural steel material is H-shaped steel or angle steel, the connection with the panel member when the H-shaped steel or angle steel is used as the structural steel material is firmly performed, and separation of both is a simple operation. Can be done with DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.
This will be described in detail with reference to FIG. The connecting tool 1 shown in FIGS. 1 to 3

A bolt 35 is inserted into the bolt insertion hole 34a provided on the outer surface side of the web 30a, and the webs 30a, 30a and the first contact portion 31 of each of the connecting members 33 are bolted to the outer surface side of the web 30a. 35A is connected in a state where the head is not exposed, and a connecting piece 30 of each H-section steel 30, 30 is connected.
By connecting the second contact portions c and 30c and the second contact portions 32 of the connection members 33 by bolts using bolts 37 and nuts 38, the heads of the bolts are exposed on the outer surface side of the web of each H-section steel. And thereby each H-beam 30, 30
The outer surfaces of the webs 30a, 30a are connected in a flat state, and the ends of the H-shaped steels 30, 30 are connected to each other by the panel member 1.
1 can be connected without hindrance. When a suitable tape or the like for waterproofing is attached to the upper surface of the mutually connected H-shaped steels 30, 30, the H-shaped steels 30, 30 can be completely prevented from being joined and flooded from the connection portion. In FIGS. 6, 7 (a) and 7 (b), 30b denotes each H-shaped steel 30, 3
The other web 40 is a reinforcing piece provided on the connecting member 33. According to the first aspect of the present invention, the contact portion of the structural steel material is not damaged by the tip portion of the second bolt, and the so-called sliding motion as in the conventional example is prevented. It is possible to provide a connector capable of firmly connecting the structural steel material and the panel member without accompanying the same, and capable of detaching the structural steel material and the panel member with a simple operation. Further, according to the present invention, a connecting tool that can firmly connect to a panel member when an H-shaped steel or an angle steel is used as a structural steel material, and that can separate the two by a simple operation Can be provided.
