Abstract

PROBLEM TO BE SOLVED: To make it possible to speedily, surely and easily fix a roof panel to a roof beam of a room unit by only taking advantage of the dead weight of the roof panel. SOLUTION: When a male type joint piece 2 is inserted from an opening on one end side of a female type joint piece 4, the front end sections of rising pieces 312 are moved to an opening on the other end side while bending them along the tapered interior wall surface of a hollow section 412. With the constitution, since claw sections 313 make acute angles with the rising pieces 312, the claw sections can be easily inserted because they move with a forward inclination while rubbing against the interior wall surface of the hollow section 412. Then, since a guide pin section is not rotated by a lock mechanism in case of insertion, the movement of the rising pieces 312 is not interrupted with the corner of the body 333. In such a joint state, since a pair of claws 313 make acute angles with the rising pieces 312 to interlock the female type joint piece 4, it is very hard to pull the male type joint piece 2 out of the female type joint piece 4, and they are surely connected to each other.

[0011]

In the factory, the one-touch joint having the above configuration is attached to, for example, the room unit and the roof panel or the roof unit corresponding to the room unit in advance. When attaching the male threaded portion of the male joint piece to the male locking hardware, a lock mechanism is used to prevent the guide pin from rotating with respect to the male locking hardware. At a construction site of a unit building, the roof panel or the roof unit is lifted by a crane, and an opening at one end side of a female joint piece attached and fixed to a frame material (second or first structural member) of the roof panel or the roof unit. Are aligned with the guide pins of the male joint piece fixed to the corresponding roof beam (first or second structural member) of the room unit, and then the roof panel or roof unit is lowered onto the room unit. Along with this, the upright piece carries the locking piece to the other end side of the inner wall of the hollow portion while bending along the tapered inner wall surface of the hollow portion. At this time, since the locking piece moves forward by tilting while rubbing the inner wall surface of the hollow portion (because it forms an acute angle with the upright piece), insertion is easy. In addition, the guide pin does not rotate due to the lock mechanism, and the state where the male screw part is first inserted into the insertion hole of the board is maintained, and the guide pin rotates and the corner of the body part interferes with the movement of the standing piece. There is no such thing. When the locking piece is discharged from the opening on the other end side of the hollow portion, it is pushed outward by the restoring force of the standing piece to lock the female joint piece. Thereby, the room unit and the roof panel or the roof unit are joined together. In this state, since the locking piece forms an acute angle with the upright piece, it is extremely difficult to pull out the male joint piece once in the engaged state from the female joint piece.

As described above, the roof panel or the roof unit can be fixed to the room unit quickly, reliably and easily by using the own weight of the roof panel or the roof unit. Therefore, the construction period can be shortened. Also, since the male joint piece is equipped with a locking mechanism, when attaching the male threaded portion of the male joint piece to the male locking hardware, the male threaded portion is simply inserted into the insertion hole to perform a troublesome fine adjustment. Without
The guide pin can be locked against rotation with respect to the male locking hardware. In addition, since the guide pin is prevented from rotating by the lock mechanism, the upright piece bends along the tapered inner wall surface of the hollow portion while the locking piece is being carried to the other end side of the inner wall of the hollow portion. Moreover, the guide pin does not rotate and the corner of the body does not interfere with the movement of the upright piece.

At this time, the inner surfaces of the upright pieces 312 and 312 and both side surfaces on the long side of the substantially rectangular cross section of the body portion 333 are arranged substantially parallel to each other.

Next, the female joint piece 4 is a hollow cylindrical cylinder (locked metal) 41 which is locked by the male joint piece 3 (claw portion of the clamp 31), and the cylinder 41 on the roof side of the eaves. It comprises a receiving nut 42 that is screwed and fixed to the joint portion of the unit 2A. The cylinder 41 has a male screw portion 411 for screwing into the receiving nut 42 and a hollow portion 412 for receiving the male joint piece 3 from below. The hollow portion 412 is open at both ends, and the inner wall thereof has a shape that tapers toward the upper side at an inclination of an angle α (FIG. 3), and at the lower end opening, there is a space for easily inserting the pair of claw portions 313, 313. At the upper end opening, the width is narrowed and its spread is set substantially equal to the distance between the outer surfaces of the pair of upright pieces 312, 312 (outer dimension of the U-shaped portion). Further, the upper end surface 413 of the cylinder 41 has a predetermined gradient (in this example, the same inclination angle β as that of the claw portion 313 of the clamp 31) in a state of flowing outward. Therefore, in the joined state of the one-touch joint, as shown in FIG.
As shown in FIG.

Will be locked. In order to fix the female joint piece 4 having the above-mentioned configuration to the girder side eaves beam 211 of the eaves side roof unit 2A, first, the receiving nut 42 is preliminarily factory-mounted on the upper surface (inner surface) of the lower flange 211a of the girder side eaves beam 211. The male joint piece insertion hole 211b is made to have a common axial center at the joining portion of the above by welding. Next, the cylinder 41 is screwed and attached to the fixed receiving nut 42.

Next, with reference to FIGS. 3 to 5, the construction for installing the eaves side roof unit 2A on the room unit 1 will be described. These units 1 and 3 are produced in a factory in advance, and are installed and assembled at a construction site as shown in FIG. In addition, in this example, the female joint piece 4 is used as the eaves side roof unit 2A in advance at the factory.
While the male joint piece 3 is installed at the construction site. Here, as described above,
Fastening bolt 3 with guide pin for male joint piece 3
When attaching 3 to the clamp 31, the hanging piece 333
a and 333a are sandwiched from the side end surface side of the base piece 311 so that the guide pin portion does not rotate with respect to the clamp 31. To assemble, first, the room unit 1 is installed by the crane K on the hoisting foundation G and connected to each other, then the male joint piece 3 is bolted and fixed to the roof beam 11, and then the eaves side roof. The unit 2A is lifted by the crane K (see the figure), and the corresponding room unit 1
Install on top of the. At this time, as shown in FIGS. 2 and 3, the roof beam 11 on the side of the room unit 1 and the girder side eaves beam 211 on the side of the eaves side roof unit 2A are placed close to each other, and the corresponding joint portions are roughly arranged. After the alignment, the clamp 31 of the male joint piece 3 is attached to the girder eaves beam 211 according to the guide pin portion of the fastening bolt 33 with the guide pin, as shown in FIGS. 6 (a) and 7 (a). The eaves side roof unit 2A is lowered onto the upper part of the room unit 1 while being inserted into the male joint piece insertion hole 211b. Then, the claw portions 313 of the clamp 31
Since the hollow portion 412 of the cylinder 41 has a tapered shape, the portion 313 contacts the inclined surface of the inner wall of the hollow portion 412.

When the eaves side roof unit 2A is continuously lowered, as shown in FIGS. 6 (b), 7 (b) and 7 (b), the upright pieces 312 and 312 of the clamp 31 are inserted to a required scale. While receiving the load and bending along the tapered inner wall surface of the hollow portion 412, the claw portions 313 and 313 are moved to the hollow portion 412.
Carry it to the upper end of 12 (hence the natural alignment of the joints). Here, the insertion load refers to the weight of the eaves side roof unit 2A, which is the eaves side roof unit 2
A value divided by the number of female joint pieces 4 attached to A, that is, a vertical load applied to each female joint piece 4. At this time, the claw portion 31
3 and 313 form an acute angle with the upright pieces 312 and 312 and move forward while rubbing the inner wall surface of the hollow portion 412, so that the insertion work is easily performed. Furthermore, when the fastening bolt 33 with the guide pin is attached to the clamp 31, the inner surfaces of the upright pieces 312 and 312 that are substantially vertically erected are substantially parallel to the side surfaces on the long side of the substantially rectangular cross section of the body 333. And the hanging pieces 332a, 33
Since the guide pin portion is locked so that the guide pin portion does not rotate with respect to the clamp 31, the standing piece 3 a is held by the base piece 311 from the side end surface side of the base piece 311, as shown in FIG. 7B.
Even when 13, 313 is closest to the body 333,
The corners of the body portion 333 do not interfere with the movement of the upright pieces 312 and 312 and the required insertion load does not increase.

When the claw portions 313 and 313 penetrate the hollow portion 412 and are discharged from the opening on the upper end side thereof, FIG.
As shown in FIG. 7C and FIG. 7C, the standing pieces 312, 3
The restoring force of 12 causes the cylinder 41 to expand along the upper end surface 413 (locked surface) of the cylinder 41, thereby locking the female joint piece 4 (hollow member 41). In this state, the claws 313 and 313 form an acute angle with respect to the upright pieces 312 and 312, so that the male joint piece 3 once in the engaged state cannot be pulled out from the female joint piece 4. It will be extremely difficult. Therefore, when an insertion load of a required scale is applied, it is only necessary to lower the eaves-side roof unit 2A to the upper part of the room unit 1, and
The two are securely joined together.

According to the above construction, when the male joint piece 3 is inserted from the opening on the one end side of the female joint piece 4 with a predetermined insertion load, the upright piece 312 becomes hollow.
While bending along the tapered inner wall surface, the tip portion advances to the opening on the other end side. With this, the claw portion 313 makes an acute angle with the upright piece 312, so that the inner wall surface of the hollow portion 412 is Easy to insert because it moves while rubbing forward while rubbing. Further, in the joined state, the pair of claw portions 313, 3
13 spreads each other and makes an acute angle with respect to the standing pieces 312 and 312 to lock the female joint piece 4, so that the male joint piece 3 once brought into the engaged state.
It is extremely difficult to pull out the female joint piece 4 from the female joint piece 4, and the joining is ensured. Therefore, the eaves side roof unit 2A can be fixed to the room unit 1 quickly and reliably and easily by using the own weight of the eaves side roof unit 2A. Can be shortened.

Further, since the head portion 332 of the fastening bolt 33 with the guide pin is provided with the hanging pieces 333a, 333a extending vertically downward from the side surfaces on both short side sides of the substantially rectangular cross section, the male joint is formed. When the fastening bolt 33 with the guide pin of the piece 3 is attached to the clamp 31, the fastening bolt 33 with the guide pin is simply inserted into the insertion hole, and the guide pin portion is clamped by the clamp 3 without troublesome fine adjustment.
It can be locked against rotation with respect to 1.
Further, once the fastening bolt 33 with the guide pin is attached to the clamp 31, the rotation of the guide pin portion is prevented, so that the standing pieces 312 and 312 bend along the tapered inner wall surface of the hollow portion 412, and While the parts 313 and 313 are being carried to the other end side of the inner wall of the hollow part 412, the guide pin part rotates and the corners of the body part 333 rise up.
It does not interfere with the movement of the 312 and increase the required insertion load. That is, when attaching the fastening bolt with the guide pin to the clamp 31 in a male joint piece having no lock mechanism for preventing the fastening bolt with the guide pin from rotating with respect to the clamp 3, for example, as shown in FIG. Set the body part 333X upright piece 3 as shown.
If you make an angle to 12,312,
In the process of connecting both joint pieces, the claw portions 313, 313
While raising the inner wall of the hollow portion 412, the upright pieces 312 and 312 move to the body portion 3 as shown in FIG.
Although it may hit the corner of 33X and the required insertion load may increase, and in the worst case, both joint pieces may not be completely connected, this situation can be avoided. Further, since the male joint piece 3 has the guide pin portion, the female joint piece fixed to the frame material of the eaves side roof unit 2A by lowering the eaves side roof unit 2A onto the room unit 1.
