[Problems to be solved by the invention]
However, in the case of Patent Documents 1 and 2, in order to stably attach and fix the thermal expansion material to the ceiling plate support, it has been necessary to newly form a groove or a step portion on the ceiling plate support.
[0005]
In general, it is necessary to close the ventilation hole of the ceiling plate support with a thermal expansion material or the like in the fire prevention section, but it is not necessary to close in the non-fire prevention section. For this reason, in the case of the site where a fire prevention zone and a non-fire prevention zone coexist, a ceiling board support with a thermal expansion material and a ceiling board support without a thermal expansion material are required. In this case, if the shape of the ceiling plate support that attaches and fixes the thermal expansion material is different from that of the ceiling plate support that does not, the two types of ceiling plate support must be prepared. For this reason, storage is also troublesome, and there is a possibility that both are confused and mistakenly constructed.
[0006]
Also, in order to securely fix the thermal expansion material to the ceiling board support, it is usually attached and fixed using a double-sided tape or an adhesive.
However, the work of fixing the thermal expansion material by applying a double-sided tape or an adhesive is time-consuming and causes labor and cost increase.
[0007]
Therefore, the present invention has been made in view of the above circumstances, and even when a ceiling plate support for a non-fire-proof section that does not require a thermal expansion material can be used, the thermal expansion material can be fixed easily and reliably, in the event of a fire. In the above, it aims at being able to be used as a ceiling board support for a fire prevention compartment that can automatically stop ventilation.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a first invention is a ceiling plate support that is attached to a wall surface and supports the ceiling plate so as to allow ventilation.
The support body that sandwiches the ceiling plate from the top and bottom is provided with ventilation slits to form a ventilation passage that leads from the ceiling plate lower surface side to the ceiling plate upper surface side,
A plate body holding a thermal expansion material is inserted into the support body, and the thermal expansion material is expanded by hot air passing through the ventilation passage so that the ventilation passage can be closed.
[0009]
In the second invention, the support body is provided with an upright portion having a mounting hole and in contact with the wall surface,
While providing several ventilation slits while extending horizontally from the upper end of the standing part, the upper surface part tilts the tip downward,
While comprising several ventilation slits extending horizontally from the lower end of the standing part, and comprising a lower surface part comprising a placing piece for raising the tip and placing the ceiling plate on the standing part side,
The plate body has a mounting hole at the same position as the standing part of the support body,
It is inserted so as to be in sliding contact with the standing part with a holding piece holding the thermal expansion material,
The elongated piece formed by the ventilation slit on the upper surface is bent toward the upright portion, and the plate body is fixed to the upright portion.
[0010]
The third invention is characterized in that an elastic body is provided on the wall surface side of the upright portion.
[0011]
DETAILED DESCRIPTION OF THE INVENTION

Here, the support tool body 11 can be used alone as a ceiling board support tool in a non-fire-proof section. The details are as described below.
[0012]
The support body 11 includes an upright portion 12 that includes an attachment hole 13 and contacts the wall surface. The ceiling board support 10 is attached to the wall surface using screws or the like in the attachment holes 13.
And while having several strips of ventilation slits 21, 21,... Extending horizontally from the upper end 14 of the upright portion 12, it has an upper surface portion 20 that inclines the tip 23 downward.
In addition, several ventilation slits 26, 26,... Are provided horizontally extending from the lower end 15 of the upright portion 12, and a mounting piece 27 is provided for placing the ceiling plate on the upright portion 12 side with its tip upright. And a lower surface portion 25.
[0013]
In this way, the support body 11 includes the ventilation slits 26, 26,... Of the lower surface portion 25 and the ventilation slits 21, 21,. A ventilation passage 29 leading to is formed. With this ventilation passage 29, the ceiling plate support 10 can support the ceiling plate so as to allow ventilation.
[0014]
On the other hand, when this support tool main body 11 is used in the fire prevention compartment, it is used as a ceiling board support for the fire prevention compartment by inserting the plate body 30 into the support tool main body 11.
The plate body 30 includes mounting holes 31, 31,... And holding pieces 32, 32,... Holding the thermal expansion material 40 at the same position as the standing part 12 of the support body 11.
The plate body 30 is inserted so as to be in sliding contact with the upright portion 12 of the support body 11.
[0015]
FIG. 2 is a cross-sectional view showing a usage state of the ceiling board support 10.
The ceiling plate support 10 places the ceiling plate 50 on the placement portion 27 of the support body 11 and supports the ceiling plate 50 so as to be sandwiched from above and below by the upper surface portion 20 that inclines the tip 23 downward.
The ceiling board 50 is inserted from the obliquely downward direction of the ceiling board support 10 with the end 51 side to be inserted into the ceiling board support 10 inclined upward. After the insertion, the ceiling board 50 is supported in a horizontal state as shown in FIG.
[0016]
Further, the plate body 30 inserted so as to be in sliding contact with the upright portion 12 of the support body 11 has an elongated piece 22 formed by the ventilation slits 21, 21,. It is fixed by bending to the 12 side. By doing so, the plate body 30 can be securely fixed to the support body 11 without using any other member.
[0017]
And when a hot air passes through the ventilation channel | path 29 formed in the ceiling board support tool 10, the thermal expansion material 40 hold | maintained at the plate body 30 will expand | swell like a broken line. As a result, the ventilation passage 29 is closed, and the ceiling board support 10 automatically stops ventilation.
[0018]
In addition, by providing an elastic body (for example, EPDM) 46 on the wall surface side of the upright portion 12 of the support body 11, the gap between the upright portion 12 and the wall surface can be filled. It becomes possible to attach the ceiling board support 10 reliably.
