Next, while explaining the procedure for constructing the ceiling structure 1 having the configuration described above, the effects of the ceiling structure 1 and the support device 50 will be explained.

In order to construct such a ceiling structure 1, first, as shown in FIGS. 2 and 4, runners 5 are arranged and screwed (see (b) of FIG. 2) on the upper walls of the corridor 2 facing each other. . The runners 5 extend along the longitudinal direction of the corridor 2 and are attached so that the openings of the U-shaped cross section face the openings of the opposing runners 5 .

After that, the horizontal member 10 is stretched between the runners 5, 5 facing each other. The horizontal member 10 spans the two elongated members 11 in such a manner that the side openings of the U-shaped cross section face each other. One end of one of the two elongated members 11, 11 is screwed to the runner 5 of one wall 3, and the other end of the other elongated member 11 is screwed to the other. screw to the runner 5 of the wall 3 of .

Both ends of a horizontal member 10 composed of two elongated members 11, 11 are surrounded by supporting members 30 and sandwiched. Specifically, the two elongated members 11 and 11 are fixed by surrounding the upper surface and the side surface of the horizontal member 10 with the gate-shaped horizontal member fixing portion 31 . Further, the lower surface of the horizontal member 10 is covered with the ceiling base receiving member 24 by fixing the ceiling base receiving member 24 to the ceiling base material fixing portion 32 at the bottom of the support member 30 . As a result, the two elongated members 11, 11 are surrounded over the entire peripheries of the upper, lower, right, and left sides, so that they are not separated from each other. Moreover, since the two elongated members 11 are not fixed to each other, they are slidable along the longitudinal direction. That is, the horizontal member 10 is elongated by sliding the two long members 11 , 11 .

According to such a horizontal member 10, when the distance between the walls 3, 3 increases during an earthquake, one long member 11 is pulled while being fixed to one wall 3, and the other long member 11 is pulled. The material 11 is pulled while being fixed to the other wall 3 . The two elongated members 11, 11 then slide relative to each other. In this way, the two elongated members 11, 11 slide following the walls 3, 3, so that the fixed portion of the horizontal member 10 can be prevented from being damaged, and the horizontal member 10 from the wall 3 can be prevented from being damaged. can prevent detachment.

In addition, the horizontal member 10 is constructed by enclosing the two elongated members 11, 11 along each other and surrounded by the support member 30 and the ceiling base receiving member 24, so that the bending stress can be resisted with a large cross section. A horizontal member can be obtained. Therefore, the seismic performance of the ceiling structure 1 can be enhanced. Furthermore, the elongated member 11 is composed of a stud with a U-shaped cross section, and the two elongated members 11, 11 are combined so that the side openings are opposed to each other, so that it is horizontally mounted. The material 10 has a cylindrical shape, and can increase its rigidity. Therefore, the seismic performance of the ceiling structure 1 can be further enhanced.

Furthermore, in this embodiment, since the horizontal members 10 are fixed to the wall 3 via the runners 5, the operation of fixing the horizontal members 10 to the wall 3 is facilitated.

In addition, by fixing the two elongated members 11, 11 via the gate-shaped support member 30, the plurality of elongated members 11, 11 can be integrally fixed. It is possible to form a horizontal member 10 that can counteract with a large cross section.

As a result, the web portion 25 a is sandwiched between the first web contact portion 55 of the first member 51 and the second web contact portion 65 of the second member 52 . Then, the first web contact portion 55, the web portion 25a, and the second web contact portion 65 are fixed with screws V. As shown in FIG.

As described above, if the ceiling plate support member 23 and the ceiling base support member 24 are fixed using the support device 50, the vertical plate portion 26a of the ceiling base support member 24 will contact the first vertical plate of the first member 51. It is sandwiched between the contact portion 54 and the second vertical plate contact portion 64 of the second member 52 . As a result, the first vertical plate contacting portion 54, the vertical plate portion 26a, and the second vertical plate contacting portion 64 are integrated in three layers, so that the fixing strength between the ceiling base support member 24 and the support device 50 is increased. becomes larger, each member is less likely to deform.

On the other hand, the web portion 25 a of the ceiling plate support member 23 is sandwiched between the first web contact portion 55 of the first member 51 and the second web contact portion 65 of the second member 52 . As a result, the first web contact portion 55, the web portion 25a, and the second web contact portion 65 are three-layered and integrated, so that the fixing strength between the ceiling plate support member 23 and the support device 50 is increased. In addition, each member is difficult to deform.

Therefore, since the fixing strength between the ceiling base support member 24 and the ceiling board support member 23 is increased, the seismic performance of the ceiling structure 1 is improved. Further, the positional relationship between the ceiling base support member 24 and the ceiling panel support member 23 is not shifted. This makes it difficult for the ceiling plate 21 and the ceiling plate support member 23 to be displaced.

Further, in the support device 50, when fixing the ceiling plate support member 23 to the ceiling base support member 24, the upper flange portion 25b is inserted into the notch portion 62 and locked, so that the ceiling plate support member 23 is fixed. The second member can be attached by temporarily fixing to the first member 51 . Therefore, construction is easy.

Further, in the support device 50, the upper side plate portion 26b of the ceiling base support member 24 and the locking plate portion 53 of the first member 51 are inserted into the upper notch portion 70 of the second member 52, and the lower side plate portion 26b The horizontal plate portion 26 c is inserted into the lower notch portion 71 of the second member 52 . That is, since the second member 52 is configured to mesh with the ceiling base support member 24, the fixing strength between the support device 50 and the ceiling base support member 24 is further increased.

Furthermore, in the ceiling structure 1, since the lower flange portion 25c of the ceiling plate support member 23 is fitted into the groove 22 formed on the outer peripheral side surface of the ceiling plate 21, the fixing strength of the ceiling plate 21 is high. Further, the ceiling plate support member 23 extends in the width direction of the corridor, and when an earthquake occurs that shakes in the longitudinal direction of the corridor, the adjacent ceiling plates 21, 21 shake in the direction perpendicular to the lower flange portion 25c. . At this time, since the ceiling plates 21, 21 are integrated with the ceiling plate support member 23 with the lower flange portion 25c interposed therebetween, they are unlikely to come off from the ceiling plate support member 23. When an earthquake swaying in the width direction of the corridor occurs, both the ceiling plate 21 and the ceiling plate support member 23 abut on the wall 3 to suppress the shaking, so that the ceiling plate 21 is hard to come off from the ceiling plate support member 23.例文帳に追加
