2. Description of the Related Art As shown in FIG. 14, in a building having a steel frame structure, an H-shaped steel 8 which is a beam erected between columns is formed with an outer wall base 13 made of steel materials fixedly arranged at appropriate intervals. Then, while the exterior material 14 such as a siding board is attached to the outer side surface of the outer wall underlayer 13, the inner wall underlayer 31 is formed on the inner side surface with a highly accurate steel material called C-type steel. An interior material 15 such as a plaster board was attached to the side surface, and a heat insulating material 16 was interposed between the outer wall foundation 13 and the interior material 15. However, such a construction method results in a thick wall structure in which the outer wall underlayer 13 and the inner wall underlayer 31 are doubled, so that the size of the room is reduced, the underlayer material becomes bulky, and the construction period becomes long. . Therefore, FIG.
A new construction method has been proposed in which the steel material for the inner wall base is omitted by utilizing the square steel material 11 as shown in FIG. With this new construction method, the beam forming H
A metal fitting 32 is welded to the shape steel 8 in the field, and a square steel material 11 for forming an outer wall base, which also serves as an inner wall, is connected and fixed by a bolt 33 attached to the metal fitting 32 using the metal fitting 32. Exterior material 1 such as siding on the outer surface of the outer wall substrate 13
4 and the interior material 15 such as plasterboard was directly attached to the inner surface. Moreover, in this new construction method,
As shown in FIG. 16, L is formed on the back surface of the lower horizontal portion of the H-shaped steel 8.
It has also been performed that the square steel material 11 is fixed by welding the U-shaped steel 34 and further using the U-shaped receiving metal fitting 35 welded to the L-shaped steel 34.

[Problems to be Solved by the Invention] It is necessary to have a high degree of skill to weld metal fittings to a proper position, and no matter how skilled a worker is, the quality control is performed by inspecting the finish and performing a durability test. It is difficult to make sure that Moreover, since the former is supported only by bolts, there is a problem in strength such as twisting, and above all, the complexity of welding work,
There was a fatal defect that there was a high possibility of defective welding. Therefore, although the development of a simple connecting tool for connecting a square steel material to an H-shaped steel has been advocated, a definitive fixing means for the H-shaped steel has not been found, and the vertically arranged square-shaped steel material is used for a roof part or the like. There is no effective solution to connect and fix slanted beams with the same metal fittings, and the spread of these products is delayed.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a connecting member and a connecting method according to the present invention will be described with reference to the drawings. FIG. 1 shows a connecting member A. The left and right parts of a stainless steel plate body 1 cut out in a cross shape that is long in the lateral direction are bent at a substantially right angle to the front side, and the pair of side plates 1a formed by the bending. With 1a, a first plate surface 2 having a holding portion having a U-shaped cross section is formed on the front side, and upper and lower parts are bent at a substantially right angle to the back side to thereby have tongue pieces 3 and 3 on the back side. The second plate surface 4 is formed. At each boundary between the upper and lower parts of the tenless plate body 1 and the second plate surface 4, cuts 6.6 extending inward from the side plate bending line 5 are provided on both sides, and as a result, each tongue piece part is formed. 3.3 is narrower than the second plate surface 4, and locking wings 7.7 ... Are connected to both sides of each of the tongue pieces 3.3. A through hole 3a is formed at the center of the tongue piece portion 3.

FIG. 2 shows a relationship between the connecting member A and a building steel frame connected by the connecting member A. One building steel frame is installed in a horizontal posture between columns. A H-shaped steel 8 used as a beam, and a T-shaped steel 9 is welded in a horizontal position on the upper surface of one side edge of the upper plate of the H-shaped steel 8 along the side edge in advance at the time of factory shipment. . Connection member A
Is connected to the H-shaped steel 8 via the T-shaped steel 9. Both the H-shaped steel 8 and the T-shaped steel 9 are manufactured in accordance with the standard, and are easily obtained by establishing a stable supply route, and welded at the factory, so the mutual dimensional accuracy and the bond strength are reliable. The degree is also extremely high. The second plate surface 5 of the connecting member A is adapted to the width of the vertical plate portion 9a of the T-shaped steel 9. Each side plate 2a.2a is provided with a screw hole 10.10 in advance. Reference numeral 11 is another square steel material as a building steel frame that is connected using the connecting member A, and is called a stud in the industry.

FIG. 3 shows an example of the procedure for connecting the H-shaped steel 8 which is a building steel frame and the square steel material 11. First, the connecting member A is attached to the vertical plate portion 9a of the T-shaped steel 9. Apply the second plate surface 5 (a in FIG. 3), for example the tongue piece 3
Insert a rod-shaped object into the through hole 3a formed in the hole, apply the principle of leverage to draw the second plate surface 5 close to each other, and keep the locking wings 7.7 ... By bending in the opposite direction, the vertical blade 9a is sandwiched between the locking wings 7 and the second plate surface 5, and the connecting member A is locked and fixed to the vertical plate 9a of the T-shaped steel 9 (see FIG. 3). b). A large plier or a hammer can be used to bend the locking wing 7, and the locking wing 7 can be easily and surely fixed only by bending the locking wing 7 in this manner. When the fixing to the T-shaped steel 9 is completed, the square steel material 11 is held by the first plate surface 1 and fixed with screws 12.12 ... (C in FIG. 3), and the outer wall foundation is fixed by repeating this work. Finalize.

Thereafter, as in the case of the conventional new method, as shown in FIG. 4, an exterior material 14 such as a siding board is attached to the outer surface of the outer wall foundation 13, and the exterior material 14 and the exterior material 14 thereof.
A heat insulating material 16 is interposed between the interior material 15 such as a plaster board directly attached to the inner surface of the. Incidentally, the connecting work of the square steel materials may be performed simultaneously while attaching the connecting member.

As described above, when the square steel material is connected and fixed to the H-shaped steel by using the connecting member of this embodiment, the workability is excellent.
Moreover, since the T-shaped steel is welded to the H-shaped steel in advance, the accuracy and reliability are increased. In the embodiment, the upper and lower edges of the first plate surface are locked by bending both the upper and lower locking blades, but in the above-described embodiment, the lower locking blades do not have to be used to provide a sufficient connecting function. Therefore, the lower locking means can be omitted.

Since the connecting member of the above embodiment is formed by bending a single stainless plate, it is simple and convenient to handle, but the cutout shape tends to be complicated. Therefore, in FIGS. 5A and 5B,
As illustrated in FIG. 2, the side plate is bent to form a bent plate body 17, and the tongue portion 4 and the locking wing 7.7 are bent to form a plate body 18 having a locking means. It is also possible to configure the connecting member A2 in which the folding plate body 17 is stacked in the U-shape corresponding to the back surface of the second plate surface 5 and the plate body 18 with the locking means is assembled so as to be tying together. In this case, if both members are caulked so as not to be separated, one member will not be lost.

When the plate body with the locking means is assembled into the U-shape of the bent plate body, the plate body 18 with the locking means is bent, though the plate body 18 with the locking means can be mounted without rattling by the side plates 2a, 2a. By assembling the plate body 17 on the side opposite to the inside of the U-shape, that is, on the side of the second plate surface 5, the relative assembly angle of both can be freely set. Therefore, if a unified standard is set for the angle of the roof, and the connecting member A2 is formed so that the assembly angle between the bending plate 17 and the plate 18 with the locking means matches the roof angle, As shown in FIG. 6, with respect to the H-shaped steel 8 which constitutes the sloping roof, the connecting metal fitting A is also connected via the T-shaped steel 9 in the same manner as described above.
It becomes possible to connect the square steel materials 11 at 2. However, if the inclination of the roof is not uniform, a connecting member having a different assembly angle is required depending on the inclination of the roof.
Therefore, it is desirable to rotatably connect them so that the angle can be adjusted according to the inclination of the beam.

Next, a description will be given of a modified embodiment in which the bending plate and the plate with the locking means can be rotated relative to each other and the relative angle between the first plate surface and the second plate surface can be adjusted. . FIG. 7 shows a bent plate member 17 having a perfect circular through hole 1.
9 is provided, while the through hole 1 is provided in the plate body 18 with locking means.
9. A tubular boss portion 20 that fits 9 is formed, and the tubular boss portion 20 is inserted into the through hole 19 and the leading end portion that has been indexed is bent outward and expanded to prevent it from coming off (see FIG. 8). The metal fitting A3 is configured. With such a structure, it can be formed by a pressing technique that effectively uses burring, and since it cannot be separated, no member is lost.

In order to make the bending plate and the plate with the locking means rotatable with respect to each other, a bolt may be used for assembly in addition to the above structure. FIG. 9 shows a modified example in which the bolts are assembled.
8 is a recess 2 that is large enough to completely accommodate the head of the bolt.
1 is pressed to form the central bolt insertion hole 22 of the recess, while the tap 23 is cut in the bent plate body 17, and the threaded portion of the bolt 24 inserted into the bolt insertion hole 22 is screwed into the tap 23. Assemble and complete the connecting metal fitting A4. Even with this configuration, as in the above, they can be assembled so as to be rotatable with respect to each other, and can be adapted to a roof beam having an arbitrary inclination angle. In the rotating type, the cylindrical boss portion and the bolt insertion hole may be formed in the bent plate body, and the combination may be reversed.

In each of the above-described embodiments, the first plate surface having the holding portion is U-shaped. However, when fixing the square steel material in the horizontal position, it is not necessary to support the upper surface.
The first plate surface may be L-shaped with one side plate omitted. Further, as the locking means, various locking means other than the wing bending locking type can be preferably used. Next, a modified example of the locking means will be described. FIG. 10 shows a tongue-folding type connecting metal fitting A5 in which the tongue piece 3 itself is bent and the edge of the vertical plate portion is held and sandwiched and fixed to the second plate surface. Therefore, productivity is improved, and if a dedicated jig for bending is used, it is possible to firmly and surely crimp with one touch, and the work is easy.

FIG. 11 employs a system in which a cut-and-raised piece is used for locking. In both (a) and (b), a tongue piece 3.3 has a U-shaped slit or a U-shaped slit, with one side as a base point. Cut and raised pieces that can be cut and raised 25.2
Connection metal fittings A6 having 5 ... The type of (a) is arranged so that the cut-and-raised pieces 25.25 face each other, and one side of the cut-and-raised piece 25 and the second plate surface sandwich and fix the vertical plate portion 9a, and the type of (b). Fixes the vertical plate portion 9a by sandwiching it with the tip edge of the cut-and-raised piece 25 and the second plate surface 5. According to this structure, it can be fixed by a simple operation such as pushing down with a driver or the like.

FIG. 12 shows a connecting metal fitting A7 adopting a wedge driving method. In FIG. 12 (a), two slits 26.26 are cut out in the tongue piece portion 3, and the piece 27 is attached to the second plate surface. It is a type that drives at a right angle to 5. (B) is a type in which a convex long hole 28 is cut and raised in the tongue portion 3, and a leaf spring 29 is driven into the long hole 28 in parallel with the second plate surface 5. With such a wedge method, workability is outstandingly good because it can be hammered in. It should be noted that each of the locking means is not limited to the embodiment shown in the drawings, but may be implemented in various forms, and may be appropriately changed without departing from the spirit of the present invention. The well-known technology of is also applied.

The connecting member of the present invention may be freely selected from metals such as brass and iron other than stainless steel, synthetic resin containing carbon fiber, etc., and the size, shape and the like may be selected according to the size of the steel material to be connected. The present invention recommends the use of a T-shaped steel welded to the upper surface of one side edge of the upper plate of the H-shaped steel, but the object for connecting the second plate surface is H-shaped steel. It is a T-shaped steel welded to the lower surface of one side edge of the lower plate of the shape steel, the upper or lower surface of one side edge of the lower plate, a combination of L-shaped steel other than the T-shaped steel, and the H-shaped steel in a vertical posture. The vertical H-shaped steel itself may be used as long as the H-shaped steel is arranged in the vertical position. Further, the connecting member of the present invention,
It can also be suitably used for a fixed frame of a large signboard, and in the embodiment, the locking means is used in a posture in which it is arranged vertically.
