The mating female member and the locking step of the guide pin attached and fixed to the roof beam (the first building structural member) can be fitted and locked to each other, and can act on the roof panel or the roof unit. The horizontal force, that is, the lateral displacement, can be resisted by the frame material of the roof panel or roof unit being locked by the guide pins inserted into the guide holes, so that the vertical load can be applied to the horizontal load. High bonding strength can be obtained. Moreover, since the roof panel or the roof unit can be quickly and reliably and easily fixed to the room unit only by utilizing the own weight of the roof panel or the roof unit, the fixing operation does not take much trouble and the stomaching work is eliminated. Therefore, the construction period can be shortened. In addition, the danger associated with the work under the suspended load can be avoided.

The wings 4 attached to the girder roof beam 11 and the gable roof beam 12 by the part 31a
The eaves beam 211 and the truss beam lower frames 221 and 221 are inserted into the guide holes 211b against horizontal force acting on the eaves-side roof unit 2, that is, lateral displacement. Since the resistance can be achieved by being locked to the guide pin 3, a high joining strength can be obtained both for a horizontal load and a vertical load. Moreover,
The eaves-side roof unit 2 can be quickly and reliably and easily fixed to the room unit 1 only by utilizing the own weight of the eaves-side roof unit 2 (the insertion load of the guide pins 3 into the guide holes 211b). Without
Eliminate stomach work. Therefore, the construction period can be shortened. In addition, the danger associated with the work under the suspended load can be avoided.

The table 41 has a lower flange 21
The guide pin 3 is slidable inside the cover 47 only when placed on the upper surface of 1a, and the inner peripheral surfaces of the opening H1 and the guide pin through hole K1 are tapered. When inserted into the guide hole 211b, the opening H1
Even if the axis of the guide pin through hole K1 is deviated from the axis of the guide pin 3, the opening H1 and the guide pin through hole K1
As the guide pin 3 is inserted along the tapered inner peripheral surface, the table 41 to which the wings 42 and 43 are attached slides so that the axes coincide.

The eaves-side roof unit 2 (eave beam 211, girder truss beam lower frames 221 and 221) is locked by the room unit 1 (eave-side girder roof beam 11, girder) by the locking step portions 31a. It is configured to be automatically locked and fixed to the roof beams 12, 12). Here, each component other than the compression coil spring 55 is formed of, for example, mild steel (SS400).

The table 51 is a rectangular plate-like member.
The opening H2 has a vertical cross-sectional shape that tapers from the bottom surface side to the upper surface side of the table 51. The size of the opening 2 is such that the guide hole 211b on the bottom surface and the guide pin 3 on the upper surface are not inserted. Guide pin through hole K2

The compression coil spring 55 is used in a state of being entirely compressed, and exerts a restoring force in a direction in which the length of the coil portion increases. The compression coil springs 55 are attached to both ends of the side end surface of each slide plate, that is, at two places.

Next, the operation of this example will be described with reference to FIGS. First, when the room unit 1 and the eaves-side roof unit 2 having the above configuration are manufactured in a factory, the room units 1 and the eaves-side roof beams 12 are provided on the upper part of the room unit 1 (the upper flange 11a of the girder roof beams 11 and the timber roof beams 12, 12). The guide pin 3 is previously fastened and fixed at the position of the mounting hole 11b, and the lower part of the eaves side roof unit 2 (eave beam 211,
The lower flange 211 of the wife truss beam lower frames 221 and 221
The one-touch locking tool 5 is attached in advance around the guide hole 211b provided in (a) (FIG. 17 (a)). These room unit 1 and eaves side roof unit 2 are produced in a factory together with other room units 1 and ridge side roof units 2A, etc., then transported to a building site, and assembled on a foundation G prepared in advance. (See FIG. 10). First, the room units 1 are installed on the foundation G and connected to each other, and then the various roof units 2 and 2A corresponding to the upper part of the installed room units 1 are installed, and these roof units 2 and 2A are interconnected. It is performed by connecting to. At this time, in order to place and fix the eaves-side roof unit 2 on the upper part of the room unit 1, the eaves-side roof unit 2 is lifted with a crane, and the lower part of the eaves-side roof unit 2 (eave beam 21).

The guide holes 211b provided in the bottom frames 221 and 221 of the truss beams are positioned on the guide pins 3 attached to the upper part of the room unit 1 (the girder roof beams 11 and the timber roof beams 12 and 12 on the eaves side). After the alignment, the roof unit 2 on the eaves side is lowered onto the room unit 1.

Accordingly, as shown in FIG. 17B, the guide pin 3 is inserted into the guide hole 211b, and first, the locking step 31a of the guide pin 3 is tapered in the opening H2 of the table 51. It is guided by the inner peripheral surface and proceeds to reach the guide pin through hole K2. Then, due to the insertion load at this time, the horizontal component of the insertion load overcomes the restoring force of the compression coil spring 55 acting on the slide plates 52 and 32, as shown in FIG. The guide pin press-contact surfaces 521a and 531a are still pushed while pushing the guide pin through-hole K2 so as to spread out.

Immediately after the locking step 31a has passed through the guide pin through hole K2, the radius of the guide pin 3 is reduced as shown in FIG. The shaft portion 31 immediately below the third portion is pressed against the guide pin pressing surfaces 521a and 531a of the slide plates 52 and 53. As a result, the slide plates 52 and 53 and the locking step 31a of the guide pin 3 are fitted and locked to each other. In this way, the eaves-side roof unit 2 is placed above the room unit 1 (the eaves-side girder roof beam 11, the
2, 12) are automatically locked and fixed. Thereafter, the eaves-side roof unit 2 and the ridge-side roof unit 2A are connected to each other with bolts and nuts, whereby the installation work of the eaves-side roof unit 2 is completed.

According to the one-touch joint having the above configuration, the slide plates 52 and 53 are locked by the locking step 31a of the guide pin 3 against the vertical force acting on the eaves-side roof unit 2. The horizontal force acting on the eaves-side roof unit 2, that is, the lateral displacement, can resist the eaves beam 211 and the truss beam lower frames 221 and 22.
1 can be resisted by being locked to the guide pin 3 inserted into the guide hole 211b, so that the same effect as in the first embodiment can be obtained.

Next, the operation of this example will be described with reference to FIGS. 26 and 27. First, when the room unit 1 and the eaves-side roof unit 2 having the above configuration are manufactured in a factory, the guide pins 6 are previously fastened and fixed at the positions of the mounting holes 11b provided in the upper flange 11a, and the lower flange 211a. One-touch type locking device 7 is attached in advance around guide hole 211b provided in FIG.
(A)). Here, the wings 72 and 73 are connected to the table 71.
First, the wings 72 and 73 are placed on the upper surface of the table 71 so that the two rivet insertion holes overlap with each other, and the rivets are inserted from below the table 71 into the long holes 71a and both the rivet insertion holes. When the head 742 abuts on the lower surface of the long hole 71a, the leg protruding from the rivet insertion hole is swaged toward the wing 72 while suppressing the head 742. Then, the table 71 on which the wings 72 and 73 are placed is fixed to the upper surface of the lower flange 211a by welding or the like by spot welding or the like.

The room unit 1 and the eaves-side roof unit 2 are different from the other room units 1 and the ridge-side roof unit 2.
A, etc., are produced in a factory, transported to a construction site, and assembled on a previously prepared foundation G (FIG. 10).
reference). First, the room units 1 are installed on the foundation G and connected to each other, and then the various roof units 2 and 2A corresponding to the upper part of the installed room units 1 are installed, and these roof units 2 and 2A are interconnected. It is performed by connecting to. At this time, in order to place and fix the eaves-side roof unit 2 on the upper part of the room unit 1, the eaves-side roof unit 2 is lifted by a crane, and the lower part of the eaves-side roof unit 2 (eave beam 211, wife truss beam lower frame 221) , 221) are aligned with the guide pins 6 attached to the upper part of the room unit 1 (the girder roof beam 11, the gable roof beams 12, 12 on the eaves side), and then the eaves side roof unit. 2 is dropped on the room unit 1.

Accordingly, the guide pin 6 is inserted into the guide hole 2.

26A, the inner peripheral surface of the guide pin through hole K3 is tapered even if the axis of the guide pin 3 is shifted leftward in the figure from the axis of the guide pin 3, for example. As the insertion of the guide pin 6 progresses, the rivets 64 are guided by the long holes 71a of the table 71, so that both the wings 72 and 73 move rightward, as shown in FIG. Both axes are coincident. Then, after reaching the state where the distal end portion of the guide pin 6 is almost in contact with the upper edge of the guide pin through hole K3, due to the insertion load at this time, as shown in FIG. Is applied to the wings 72, 73 by a tension coil spring 75.

Then, the portion having the maximum diameter at the distal end portion of the guide pin 6 penetrates and stops at a portion having a predetermined diameter of the locking tapered portion 61a as shown in FIG. Here, the locking tapered portion 61a is pressed against the guide pin pressing surfaces 721a, 731a by the spring force of the tension coil spring 75, and the wings 72, 73 are locked by the locking tapered portion 61a. In this way, the eaves-side roof unit 2 is placed above the room unit 1 (the eaves-side girder roof beams 11, the timber roof beams 12,
12) Automatically locked and fixed. Thereafter, the eaves-side roof unit 2 and the ridge-side roof unit 2A are connected to each other with bolts and nuts, whereby the installation work of the eaves-side roof unit 2 is completed.

According to the one-touch joint having the above-described structure, the locking taper of the guide pin 6 attached to the eaves beam 211 or the truss beam lower frames 221 and 221 is not affected by the vertical force acting on the eaves roof unit 2. The wings 72 and 73 attached to the girder roof beam 11 and the gable roof beam 12 can be resisted by the portion 61a, and can resist the horizontal force acting on the eaves side roof unit 2, that is, the lateral displacement. Since the eaves beam 211 and the truss beam lower frames 221 and 221 are locked by the guide pins 6 inserted into the guide holes 211b, resistance can be obtained, and therefore, high joining can be performed with respect to both horizontal and vertical loads. Strength can be obtained.

Moreover, the eaves roof unit 2 can be quickly, reliably and easily fixed to the room unit 1 only by utilizing the own weight of the eaves roof unit 2 (the insertion load of the guide pins 6 into the guide holes 211b). In addition, the fixing work does not take time and the stomaching work is eliminated. therefore,
The construction period can be shortened. In addition, the danger associated with the work under the suspended load can be avoided.

The rivet 74 to which the wings 72 and 73 are attached is elongated so that it can be moved in the horizontal direction.
1a, is mounted and supported on the table 71,
Further, since the inner peripheral surface of the guide pin through hole K3 is tapered, when the guide pin 6 is inserted into the guide hole 211b, the axis of the guide pin through hole K3 is aligned with the axis of the guide pin 3. Even if it is deviated, as the guide pin 6 is inserted along the tapered inner peripheral surface of the guide pin through-hole K3, the wings 72 and 73 move together, so that both axes coincide. Further, since the guide pin 6 is provided with the locking tapered portion 61a so that the gradient changes sharply, the vertical direction after the guide pin is inserted, which occurs when a step is provided at a substantially right angle, is generated. The rattling can be suppressed.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like that do not depart from the gist of the present invention. Is also included in the present invention. For example, when joining a roof unit, bolt joining may be used together.
Conversely, if sufficient joining strength can be obtained only by joining the eaves beam of the roof unit and the room unit, the joining between the wife truss beam and the room unit may be omitted. In addition, the roof unit to be joined is not limited to the roof unit on the eaves side,
The ridge side roof unit may be used. Similarly, not only the gable roof unit but also a ridge roof unit may be used.

In the above-described embodiment, the case where the roof unit having the truss beams is fixed to the room unit has been described. However, the present invention is also applicable to the case where the roof panel having no truss beams is directly fixed to the room unit. Of course, it is preferable to use a one-touch joint. Also,
In the above-described embodiment, the guide pins are screwed to the upper part of the room unit (the girder roof beams 11, the girder roof beams 12, 12 on the eaves side), but may be fixed by welding instead of screwing. good.

3, 83 to be able to rotate, torsion coil spring 8
A one-touch locking tool 8 configured to sandwich the guide pin 3 from both sides in a fitted state by the spring force of 4, 84 may be used. In the above-described first embodiment, the table 41 is only placed on the upper surface of the lower flange 211a, and is slidable inside the cover 47. However, the table 41 may be slid, for example, by spot welding.
It may be fixed to the upper surface of 11a. In this case, the cover 47 may be omitted.

In the one-touch locking device 4 of the first embodiment, the tension coil spring 45 is
2,433, for example, as shown in FIG. 29, a one-touch locking device in which the tension coil spring 94 is fixed to the distal ends of the fitting female pieces 911, 921 of the wings 91, 92. 9 may be used. In the above-described embodiment, the guide pin 3 (6) is provided on the upper part of the room unit 1.
And the case where the one-touch locking device 4 (5, 7) is attached to the lower portion of the eaves-side roof unit 2 has been described.
Alternatively, the one-touch locking device 4 (5, 7) may be attached to the upper part of the room unit 1 and the guide pin 3 (6) may be attached to the lower part of the roof unit 1 on the eaves side. .
Further, the one-touch joint of the present invention can be used not only for joining a room unit and a roof unit, but also for joining a room unit on an upper floor and a room unit on a lower floor. Similarly, the present invention is not limited to the unit-to-unit and unit-panel-to-panel joints, but can also be applied to the joining between members.

[0063]

As described above, according to the one-touch joint of the present invention, the first building structural member and the second building structural member can be separated from each other by the first force.
The locking step of the guide pin fixed to the architectural structural member and the set of mating female members mounted to the second structural member are fitted and locked to each other, so that resistance can be achieved. With respect to the force for sliding the first building structural member and the second building structural member, that is, the lateral displacement, the second building structural member is engaged with the guide pin inserted into the guide hole. By stopping, resistance can be obtained, so that high joining strength can be obtained both for a horizontal load and a vertical load.

Further, the guide pin fixed to the first building structural member is inserted into the one-touch locking device mounted on the second building structural member with a predetermined insertion load, and the first pin is inserted. Since the architectural structural member and the second architectural structural member are securely joined, the fixing operation is quick and easy.

Accordingly, the guide pins are attached and fixed to the upper part of the room unit (the first building structural member) and the lower part of the roof panel or the roof unit (the second structural member).
Of the roof panel or the roof unit can be quickly, reliably and easily fixed to the room unit only by utilizing the own weight of the roof panel or the roof unit. Therefore, the fixing work does not take much time, and the stomaching work is also eliminated. Therefore, the construction period can be shortened. In addition, the danger associated with the work under the suspended load can be avoided.
