[Problems to be solved by the invention]
In the conventional firing method described above, it is necessary to cut the bolt insertion hole by accurately marking the mounting position of the firing method on the structural material at a position that is equidistant from the corners of the corners with respect to the two materials and at a horizontal position. was there. This work is very troublesome, and if the accuracy of the blackening is poor, the end of the fire is not aligned with the side surface of the structural material, and the mounting accuracy of the fire is reduced, and there is a problem that a predetermined strength is not exhibited.
[0008]
In addition, since the fire is attached after the frame is formed by columns, beams, body-inserts, etc., a work scaffold such as a floor set is not sufficient. For this reason, workers often work in an unstable state using a stepladder or the like, so that one worker is not enough, and a plurality of workers may be needed.
[0009]
Under such circumstances, in the construction process of the frame structure, it is required to shorten the construction time while securing a predetermined earthquake-resistant strength, and a reliable and quick fire-attaching work has been an issue.
[0010]
The present invention has been made in view of the above circumstances, and enhances the accuracy of sumi-toning to the inner surface of a structural material such as a base, a floor beam, a shed beam, an eaves girder, and allows a reliable and quick installation. It is an object of the present invention to provide a possible fire hammer and to contribute to the realization of a strong floor structure using the fire hammer.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention relates to a fire-fighting method in which two structural members are arranged at a corner where the two structural materials are joined at right angles, and a bolt-shaped shaft portion is provided at both ends of a rod having a fixed length. And a fixture that can be attached to both ends of the body, the fixture is abutting against an inner surface of the structural material and fixed, and the attachment surface And a main body holding surface provided at an angle of 45 ° with respect to the main body. The main body holding surface is provided with a hook that allows the shaft of the fired body to be inserted. The fired body and the fixture are connected by inserting the shaft portion of the fired body and fastening nuts from both the front and back surfaces of the body holding surface.
[0012]
According to the present invention, the substantial length of the fire main body can be finely adjusted by the fastening position of the nut in the shaft portion of the fire main body. Therefore, it is possible to attach a fire without depending on the blacking accuracy at the construction site. In addition, since the mounting operation of the fire main body only needs to insert the shaft portion into the hook portion and fasten the nut, the number of work steps is reduced, and the work can be performed accurately and quickly.
[0013]
In the fire striking having the above-described configuration, the fixing tool has a screw hole and a bolt hole on the mounting surface, and can be mounted on the structural material by the screw and the bolt. According to this, the shaft part of the fire body and the fixing device separate from each other can be attached to a predetermined position of the structural material in advance at a factory or the like, and the work at the construction site is further simplified.
[0014]
Further, the mounting surface of the fixture is provided with a claw portion that cuts into the inner surface of the structural material. According to this, at the time of the construction of the fire, by making the claws bite into the structural material, it becomes easier to attach the fixing device to the structural material, and it is possible to prevent the displacement from the predetermined position and to fix the fixture. An increase in fixing strength can also be expected.
[0015]
Further, the fixing device has a lip portion at an end portion of the main body holding surface for preventing a shaft portion fastened with a nut from coming off. Thereby, it is possible to prevent the shaft portion fastened with the nut from falling off from the hook portion.
[0016]
In the fire according to the present invention, the bolt hole and the hook of the fixing tool may be provided eccentrically in the direction of the normal to the surface constituting the corner. According to this, inside the fixture, it is possible to avoid interference between the tip of the bolt fastened to the mounting surface and the shaft portion of the fired body fastened to the body holding surface.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a fire blow according to the present invention will be described with reference to the drawings.
[0018]

FIG. 1 is a top view showing the overall configuration and use state of a fire hammer, and FIG. 2 is a (a) partial sectional view and (b) an end projection of a fire hammer body. FIG. 3 is a projection view and a cross-sectional view taken along line AA of the fixture shown by trigonometry, and FIG. 4 is a projection view and a cross-sectional view taken along line BB of a fixture having another form.
[0019]
As shown in the drawing, the fire strike 1 is arranged at a corner where two structural members 5 are joined at right angles. The fire hammer 1 includes a fire hammer 2 having a fixed length and fixing members 3 which can be attached to both ends of the fire hammer 2. The fire striking 1 is arranged at an angle of about 45 ° with respect to each structural material 5 in parallel with a construction surface (horizontal construction surface) that forms the corner by two structural materials 5.
[0020]
The flinting main body 2 is formed of a hollow round bar formed of a rolled structural steel material or the like. Bolt-shaped shaft portions 21 are welded to both ends of the firing body 2 and extend on the shaft core.
[0021]
The fixture 3 (3a) is formed of a rolled structural steel material or the like, similarly to the main body 2. The fixing device 3 includes a mounting surface 31 fixed to the inner surface of the structural member 5 in contact with the inner surface thereof, and a main body holding surface 32 continuously provided at an angle of 45 ° with respect to the mounting surface 31. Are formed in a substantially box shape by connecting the side edges of the mounting surface 31 and the main body holding surface 32 so as to be sandwiched from both sides by the outer surface plate 33.
[0022]
A screw hole 311 and a bolt hole 312 are provided on the mounting surface 31 of the fixture 3. The screw holes 311 are evenly arranged at two positions on the edge of the mounting surface 31. In addition, the bolt hole 312 is provided at a position slightly eccentric from the center of the mounting surface 31 in the direction of the normal to the construction surface forming the corner. Further, the mounting surface 31 is provided with a claw portion 313 that cuts into the inner surface of the structural material 5. In the illustrated embodiment, three claws 313 are provided at the end of the mounting surface 31.
[0023]
The main body holding surface 32 is provided with a hook 321 into which the shaft 21 of the fire main body 2 can be inserted. The engaging portion 321 is formed in a long groove shape which is formed by cutting out a part of the main body holding surface 32 and opening at an end. An inwardly bent lip 322 is formed at an end of the main body holding surface 32.
[0024]
It is preferable that the fire main body 2 and the fixture 3 configured as described above are applied to the structural material 5 as follows.
[0025]
First, the fixture 3 is positioned at a predetermined position on the inner surface of the structural member 5. Then, the fixing member 3 is temporarily fixed to the structural member 5 by using a screw 34 to fix the fixing member 3 to the structural member 5 while making the claw portion 313 of the fixing member 3 bite into the inner surface of the structural member 5.
[0026]
Subsequently, the bolt 35 is inserted into the bolt insertion hole formed in the structural material 5 and the bolt hole 312 of the mounting surface 31 to be tightly connected. By performing such a work at both ends of the main body 2, the attachment of the fixture 3 to the structural member 5 is completed. As described above, since the fixing tool 3 and the fire main body 2 are configured separately, the mounting work of the fixing tool 3 can be performed not only directly at the construction site but also in a factory or the like in advance.
[0027]
Next, the fire main body 2 is connected to the fixture 3. As shown on the right side of FIG. 2A, two sets of hexagon nuts 22 and flat washers 23 are screwed into the shaft portions 21 at both ends of the fire main body 2 in a face-to-face state.
[0028]
At this time, it is preferable to provide the flat washers 23 at appropriate intervals. Specifically, it is sufficient that there is an interval between the flat washers 23 that is equal to the projection length of the lip portion 322 in addition to the thickness of the main body holding surface 32 of the fixture 3. Then, the shaft portions 21 at both ends prepared as described above are horizontally inserted into the hook portions 321 of the fixtures 3 fixed to the structural material 5.
[0029]
Subsequently, as shown in FIG. 5, the hexagonal nuts 22 screwed to the shaft portion 21 are respectively fastened and fastened from both the front and back sides of the main body holding surface 32 of the fixture 3. Since the lip portion is provided on the main body holding surface 32, the shaft portion 21 fastened with the nut does not fall out of the hook portion 321.
[0030]
Here, by adjusting the position of the hexagonal nut 22 screwed to the shaft portion 21 of the main body 2, it is possible to finely adjust the substantial length of the main body 2. In addition, by adjusting the fastening position of the shaft portion 21 back and forth in the hook portion 321 of the fixture 3, the horizontal mounting position of the firing body 2 can be finely adjusted. Therefore, even if the blacking accuracy of the mounting position of the flint 1 is somewhat poor, the flint main body 2 can be securely attached by such adjustment, and sufficient strength is developed.
[0031]
By the above operation, the fire body 2 and the fixture 3 are connected, and the construction of the fire 1 is completed. In addition, as shown in FIG. 6, in the case where the fire 1 is attached to both of the adjacent corners, the fixtures 3 are attached to both side surfaces of one structural material 5, and these are fixed by one bolt 35. The components 3 can be tied together.
[0032]
In the present embodiment, two different configurations are prepared for the position of the hook 321 of the main body holding surface 32 and the bolt holes 312 of the mounting surface 31. That is, the bolt hole 312 and the hook portion 321 are provided eccentrically in the normal direction of the construction surface forming the corner, and in the fixture 3a shown in FIG. Below, the hook part 321 is formed above the center in the vertical direction. Further, in the fixing device 3b shown in FIG. 4, in contrast to the fixing device 3a, the bolt holes 312 are formed above the center in the vertical direction, and the hook portions 321 are formed below the center in the vertical direction.
[0033]
Thereby, on the inner side surface of the structural material 5 at the corner, the height position where the fixing member 3 is attached can be coped with both the case where the two members are the same or different, and the fixing member 3a and the fixing member 3b. By using in combination with each other, it is possible to align the height positions of the hook portions 321 with each other.
[0034]

FIG. 9 is a side view showing a state where the fire is attached to a joint between hut beams having a large cross section.
[0035]
In the fire striking 1 according to the illustrated embodiment, at the joint between the hut beams 5a in FIG. 7, a fixing tool 3a is attached to one hut beam 5a, and a fixing tool 3b is attached to the other hut beam 5a.
[0036]
In addition, the fire striking 1 is not only attached to the structural members 5 of the same kind as described above, but the structural members 5 are made of different types, for example, a joint portion between the eaves girder 5b and the hut beam 5a shown in FIG. In some cases, it can be suitably implemented. That is, since the mounting heights of the two members are different at the joint between the eaves girder 5b and the hut beam 5a, the fixtures 3 at both ends of the fire body 2 cannot be mounted at the same height position. By attaching the fixture 3a to the hut beam 5a in a state where the fixture 3a is inverted, the fire main body 2 can be held horizontally while the attachment position of the fixture 3 is changed.
[0037]
Further, in the fire striking 1 according to the present invention, not only the fixing tool 3 is attached in contact with the upper surface or the lower surface of the structural material 5 to fix the fire strut main body 2 but also, as shown in FIG. The fixture 3 can also be attached at the center. As described above, the present invention can also be suitably applied to a jointed corner such as a hut beam having a large beam.
[0038]
In addition, the fire according to the present invention is not limited to the fixing device having a substantially box shape, and may be, for example, a triangular shape in a top view as long as the mounting surface and the main body holding surface are formed at an angle of 45 °. The desired effect can be obtained even if it is formed in the form.
