DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an H-steel cross-connecting device which can easily and safely and securely connect and fix H-steel materials frequently used in civil engineering and construction works.

[0002]

2. Description of the Related Art In civil engineering work, various protective shelves and retaining shelves for construction are formed in advance, and in construction work, the main pillars forming a skeleton and the construction of temporary structures or existing structures are constructed. When a simple structure such as a store or a warehouse is constructed by reusing the space described above, a large amount of H steel is used due to its excellent toughness and handleability. By the way, the H steel materials used in these materials naturally need to be connected to each other to have a long shape in accordance with the purpose of use, or to be variously cross-connected so as to be adaptable to the structure. Conventionally, as shown in FIG. 5, the H steel members A are connected to each other, and a connecting plate B is joined to the connecting portion, and the connecting plate B and the H steel members A are screwed together with a number of connecting bolts C. At the time of crimped connection or cross connection, the other H steel material A is joined so as to be orthogonal to the H steel material A, and a connection corner plate D bent at a substantially right angle so as to be joined to the joint portion is joined. Then, the connecting corner plate D and the H steel material A are screwed and tightened with a number of connecting bolts C to connect them, and further, as shown in FIG. Pre B and one end of the connecting corner plate D are welded and fixed E to one H steel material A, and then connected to the other H steel material A by screwing and crimping using a number of connecting bolts C. Have been.

[0003] In the present connection means of the H steel material A, an extremely large number of connection bolts C are prepared together with a large number of connection plates B and connection corner plates D, and the connection bolts C for connection and fixing are inserted. A large number of connecting bolt insertion holes must be pre-drilled in the H-steel material, and one end of the connecting plate B or the connecting corner plate D is welded to fix the connection. In addition, the cost increases, and enormous labor and time are required for the connecting and fixing work. Further, in such connection fixing, H is set corresponding to the position of the connection bolt insertion hole formed in the connection plate B or the connection corner plate D.
Since the connecting bolt insertion hole is also drilled at the position of the steel material A, especially when the H steel materials A to be cross-connected have errors in the vertical and horizontal directions, the connecting bolt C cannot be inserted or the connection cannot be fixed. There is also danger of becoming.

In addition, protective shelves and retaining shelves in civil engineering work, temporary structures in building work and the like are dismantled and removed at the end of the construction work. Although the disassembly and rebuilding are carried out in a short period of time due to the remodeling and renovation etc. due to the rapid change of the method, the current method of connecting the H steel material A, especially the method of welding one end of the connection plate B and the connection corner plate D Is difficult to disassemble and reuse, and the connection plate B and the connection corner plate D are connected and fixed with a large number of connection bolts C after screwing and tightening. Requires a great deal of labor and time, and even when dismantled and reused, many connecting bolt insertion holes are drilled and these are obstacles. It has also become a result which is not able to effect re-use.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem, and the present invention is used in a pair, and one H is inserted into a holding portion formed on a vertical plate.
A cross-connecting tool for H-steel material that can easily and safely cross-connect and fix the steel material flange edge and the other H-steel material flange edge in a sandwiching portion formed on the horizontal plate, respectively. Is to provide.

[0006]

The technical means used by the present invention to solve the above-mentioned problem is used in a pair of sets, and the pair of sets is connected and connected by screwing and tightening of a tightening bolt. A horizontal plate and a horizontal plate bent at the same length and less than half the flange width of the H-steel material so that the flange edges of the H-steel materials are sandwiched and firmly locked and fixed. A substantially triangular reinforcing plate joined to the inner surface of the vertical plate and the inner surface of the horizontal plate is formed by welding on one side edge of the substrate having the plate and the outer side of the vertical plate and the horizontal plate at the other end of the substrate. On the outer side, a sandwiching portion forming plate bent toward the opposite side is formed so as to form a sandwiching portion between the outer surface of the vertical plate and the outer surface of the horizontal plate so that the flange edge of the H steel material can be inserted and inserted therethrough. The flange edge of the H steel material is more firmly formed on the inner wall surface of the sandwiched portion. The locking projection is formed in order to stop fixed, Thus in a substantially central position of the reinforcing plate consists in construction of cross-coupling of H steel Shimechijimi bolt insertion holes of the appropriate fraction size is being drilled.

[0007]

The present invention has the following functions because it uses the above technical means. That is, the board has a vertical plate and a horizontal plate which are not more than half the width of the H steel material flange width and which are equally long and bent at right angles, and one side edge of the substrate has a vertical plate inner surface and a horizontal plate inner surface. A substantially triangular reinforcing plate is welded to the outer surface of the vertical plate and the horizontal plate at the other end of the substrate, and an H steel flange edge is provided between the outer surface of the vertical plate and the outer surface of the horizontal plate. An insertion portion forming plate bent in the opposite direction is formed by welding so that an insertion portion through which the insertion portion can be inserted is formed, and furthermore, a locking projection is formed on the inner wall surface of the insertion portion. At the same time, since the tightening bolt insertion hole is formed at the approximate center position of the reinforcing plate,
At a required position of the vertically used H steel material among the mutually connected H steel materials, a pair of the vertically used H steel material flange edges are symmetrically inserted into the insertion portion formed on the vertical plate. As a result, the end flange edges of the H steel material used horizontally are also inserted into the insertion portions formed on the horizontal plate. By inserting appropriate tightening bolts into the tightening bolt insertion holes formed at substantially the center positions of the reinforcing plates and screwing and tightening the reinforcing plates, the length between the sandwiching portions is reduced. H is substantially smaller than the steel flange length.
The flange edge of the flange end of the steel material is firmly crimped to each of the insertion portions, and secure and secure locking is performed in combination with the locking projections formed on the inner wall surface of the insertion portion. Furthermore, in the present invention, it is possible to use the H steel material without any processing, and at the time of the connection work, only loosen the tightening bolt,
Not only can the connecting position of the vertical H steel material be adjusted freely, but also when the length of the horizontal H steel material changes, it can be freely adjusted according to the degree of insertion into the insertion portion formed on the horizontal plate. In addition, even when an excessive load is applied to the horizontal H steel material, the reinforcing plate is welded to the inner surface of the vertical plate and the inner surface of the horizontal plate, so that the reinforcing plate can be sufficiently held without risk of deformation. Further, the mutual H steel materials cross-connected by the screwing of the tightening bolts can be dismantled immediately.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the present invention, and FIG. 2 is an enlarged explanatory view of an insertion portion. The present invention can withstand an enormous load. Since it is used for cross connection of H steel materials, naturally, a material that is tough, hard and rigid and has excellent workability is used. In general, a steel plate material is suitable and its specific thickness is Depending on the load capacity during use, a material having a thickness of about 6 to 20 mm is generally used. And the substrate 1 formed of such a material,
The width is at most 1/2 of the width of the flange 7A of the H steel material 7.
The substrate 1 is formed as follows, and the substrate 1 is bent at a right angle at an equal length to form a vertical plate 1A and a horizontal plate 1B. In such a case, the lengths of the vertical plate 1A and the horizontal plate 1B are slightly different depending on the size of the H steel members 7 that are cross-connected. About 15 cm is desired.

On one side edge 1C of the substrate 1 thus formed,
A substantially triangular reinforcing plate 2 is welded to the inner surface of the vertical plate 1A and the inner surface of the horizontal plate 1B. The reinforcing plate 2 protects the substrate 1 from being deformed by an excessive load applied to the vertical plate 1A and the horizontal plate 1B when the cross-connected H steel members 7 are practically used. 1
Since the inner material A and the inner surface of the horizontal plate 1B are formed by welding, the material used is the same as the material used to form the substrate 1. It should be noted that the reinforcing plate 2 is not formed beyond the one side edge 1C of the substrate 1 not only in the reinforcing plate 2 itself but also in the welded portion.

The other end 1D of the substrate 1 has an H steel material 7 cross-connected between the outer surface of the vertical plate 1A and the outer surface of the horizontal plate 1B outside the vertical plate 1A and the horizontal plate 1B. Insertion portion forming plates 4A and 4B which are bent in opposite directions are formed by welding so as to form insertion portions 3A and 3B which can insert and insert the edge of the flange 7A. In such a case, the insertion gap between the insertion portions 3A and 3B is determined by the thickness of the flange 7A of the H steel material 7 to be inserted, and the length of the insertion portion forming plates 4A and 4B is equal to the vertical plate 1A. Although it is formed to have substantially the same length as the horizontal plate 1B, the substantial width of the portion bent in the opposite direction is formed smaller than the width of the substrate 1. That is, the reason is that the insertion portion 3A
The flange 7A of the H steel material 7 inserted between the flange 7A and 3B is due to the fact that, due to the characteristics of the H steel material 7, the substantial width of the flange 7A is shorter than the outer width thereof due to the presence of the web 7B. Further, since the sandwiching portion forming plates 4A and 4B are also required to be tough, hard and rigid, and have good workability, the same material as the material for forming the substrate 1 is used. In addition, it is desirable to form a large number of fine locking projections 30 on the inner wall surfaces of the sandwiching portions 3A and 3B in order to secure and secure the connection and fixation. As a specific forming means, the portions corresponding to the inner wall surfaces of the sandwiching portion forming plates 4A and 4B may be formed by forming the locking projections 30 by cutting or the like and welding them. At the approximate center position of the reinforcing plate 2, a suitable tightening bolt 6 is inserted through a pair of pairs and screwed and compressed, whereby the inserting portions 3 </ b> A and 3 </ b>
Each of the cross-connecting tools 8 of the present invention is formed by perforating a constriction bottle insertion hole 5 for inserting the flange 7A edge of the H steel material 7 into B and firmly compressing it.

FIG. 3 is an explanatory view of the connecting method of the present invention, and FIG. 4 is a view of a use mode of the present invention.
When the steel members 7 are cross-connected to each other, a pair of pairs of the present invention connecting tools 8 is provided outside the vertical plate 1A at a connection position between the H steel material 70A used vertically and the H steel material 70B used horizontally for connection. By sandwiching both side edges of the flange 71A of the H steel material 70A into the formed sandwiching portion 3A, the sandwiching portion 3B formed outside the horizontal plate 1B is also horizontally connected for connection with the sandwiching. H steel 70B used
Of both ends of the flange 71B at the end portion of the end portion. The appropriate tightening bolts 6 are inserted into the tightening bolt insertion holes 5 drilled in the mutually reinforcing plates 2 arranged opposite to each other and screwed and tightened, so that the H steel material 70 which is used vertically is used.
A flange 71A on both sides of the flange 71A at the end of the H-steel 70B used horizontally and the sandwiching portions 3A formed on the vertical plate 1A are firmly press-bonded to each other,
The mutually sandwiched portions 3B formed on the horizontal plate 1B are firmly pressed together, and the H steel materials are firmly locked and fixed to each other so that cross connection is made. Further, the inserting portion 3A and the inserting portion 3B
In the case where the locking projection 30 is formed on the inner wall surface, stronger locking and fixing can be realized.

A tightening bolt insertion hole 5 formed in the reinforcing plate 2
Is not particularly limited to one. When the area of the reinforcing plate 2 is sufficiently large, an appropriate number of tightening bolt insertion holes 5 are formed, and the appropriate number of tightening bolts 6 are screwed together. It can also be adopted. The tightening bolt 6 is appropriately selected depending on the load applied to the cross-connected H-steel material 7 and the size of the reinforcing plate 2, etc., but is generally about 16 to 20 in terms of its diameter.
A high tension bolt of about mmφ is suitable.

[0014]

As described above, according to the present invention, a tough and rigid material is used, and the width thereof is equal to or less than 1/2 of the flange width of the H steel material to be cross-coupled, and is bent at a right angle. A substrate having a vertical plate and a horizontal plate, and a substantially triangular reinforcing plate is formed on one side edge of the substrate by welding with the inner surface of the vertical plate and the inner surface of the horizontal plate. Is formed with a sandwiching portion forming plate bent in the opposite direction by welding so that a sandwiching portion through which a flange of H steel material can be inserted and inserted is formed outside the vertical plate and the horizontal plate. Also, a locking projection is also formed on the reinforcing plate, and a tightening bolt insertion hole is formed at a substantially central position of the reinforcing plate. Hang the flange edge at the appropriate position of the H steel material used vertically The flange edge of the end of the H steel material used horizontally is also inserted into the mutual insertion portion formed on the horizontal plate, and the mutual reinforcing plate is fastened. The H steel material is safely and firmly locked and fixed to the insertion portion simply by screwing and tightening with the compression bolt, so that the H steel material is easily cross-connected. And just by loosening the tightening bolts, it is possible to adjust not only the cross connection position of the H steel material used vertically, and the absorption of the fluctuation of the length of the H steel material used horizontally, but also at the end of civil engineering and construction work,
Dismantling is possible immediately by screwing the tightening bolt. In addition, in the use of the present invention, the H steel material can be used without any processing, so that it can be reused after disassembly. In addition, the present invention uses the same structure in a pair so that cross connection can be achieved. This is a connecting tool for H steel material that has excellent features such as being able to be provided at very low cost because it can be made.
