Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for attaching a cover material at an expansion joint that connects ceiling materials of opposing building frames.

(Prior art and its problems) In general, the ceiling material of opposing building frames is suspended from metal fittings such as bolts suspended from the ceiling wall of the structure, so when the ceiling material is pushed up from below, the ceiling material also lifts up. It is configured as follows. However, in such a configuration, the covering material that covers the gap between the opposing ceiling materials is pressed against the covering material holder attached to one ceiling material, thereby causing the locking portion of the covering material to engage with the holder. This is inconvenient in the type of expansion joint that elastically engages with the stop (for example, Utility Model Application No. 15708/1983). This is because in order to attach the cover material to the holder, one of the ceiling materials must be pushed up, but at this time, the ceiling material not only lifts up, but also
Conventional holders were made of spring material, so when the cover material was pressed, the holder also retreated to the back side of the ceiling material due to its elasticity, so it had to be pressed quite strongly, making it difficult to properly engage the cover material and holder. This is because it is difficult to do so. For the same reason, when screwing the holder from below one of the ceiling materials, the work was troublesome because the ceiling material would float up.

Further, with the above type of expansion joint, as time passes due to the weight of the cover material, it becomes impossible to maintain close contact between the ceiling material on the non-attached side and the cover material, and there is a risk that a gap may occur.

(Technical Problem of the Invention) An object of the present invention is to solve the above-mentioned drawbacks and provide a mounting device for a cover material in an expansion joint that can easily and reliably attach a cover material to a ceiling material. purpose.

(Means for Solving the Problems) In order to solve the above problems, a mounting device for a cover material in an expansion joint according to the present invention suspends a supporting member on the back side of a ceiling material of an opposing building frame. A holder is attached to the support member, and the holder is provided with a locking part that faces the front side from the gap between the ceiling materials, and both sides of the metal overhang provided on both sides of the holder are attached to the front side of each opposing ceiling material. The holder is characterized in that a locking portion provided on the back side of a cover material that covers a gap between the opposing ceiling materials and slidably abuts on the locking portion of the holder.

(Operations and Effects of the Invention) As described above, according to the present invention, metal overhangs are provided on both sides of the holder, and the metal overhang extends over the lower surface of the ceiling material of the building frame that faces these overhangs. Because of this contact, the holder is held at a position where the projecting portion is in contact with the lower surface of the ceiling material. Therefore, the locking portion of the holder is also held at the same position and cannot be pushed up any further. Therefore, when the cover material is pushed up and the locking part on the back side is locked with the locking part of the holder, the locking part of the holder does not retreat to the back side of the ceiling material due to the pushing up of the cover material. Therefore, both locking portions can be locked easily and reliably just by pushing up the cover material.

In addition, since the cover material is attached to a holder and comes into contact with the opposing ceiling material, and the holder and cover material are slidable against the ceiling material, the building frame may shift due to earthquakes, uneven settlement, etc. Even if the ceiling material is displaced, the cover material can respond to this displacement.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In the figure, numerals 1 and 1 indicate ceiling materials of building frames facing each other at a constant interval. The ceiling materials 1, 1 are each fixed to the lower surface of a roof edge 2, 2 which is suspended by metal fittings such as bolts (not shown). There is an expansion joint A between the opposing ceiling materials 1 and 1.
is provided. This expansion joint A is made by attaching a cover material 3 to a holder 4. The holder 4 is longer than the gap between the ceiling materials 1 and 1, has a recessed portion 5a in the center, and has an overhang on both sides. A short metal overhang member 5 having portions 5b, 5b, a locking member 6 made of a metal spring attached to the inside of a recess 5a formed at the center thereof, and a mounting member provided outside the recess 5a. It is composed of a metal fitting 7. The locking member 6 is formed by bending opposing ends of a spring piece having a substantially C-shaped cross section inward to form a locking portion 6 in an inverted V-shape.
It is formed by a. The mounting bracket 7 has a bent portion 7a formed at the upper end, a horizontal piece 7b at the lower end, and a screw receiving portion 7c formed on the horizontal piece 7b. The screw 8 passed through the overhanging member 5 from the locking member 6 is screwed into the screw receiving portion 7c of the horizontal piece 7b of the mounting bracket 7, thereby forming an integrated holder 4. It goes without saying that a nut may be used instead of the screw receiving portion 7c. Holder 4 is used for ceiling materials 1, 1 of opposing building frames.
The holder 4 is slidably attached by engaging the mounting brackets 7 to each support member 9 that is hung at a predetermined interval from the edges 2, 2 on the back side of the holder 4, and the overhangs provided on both sides of the holder 4 projecting members 5b on both sides of the member 5;
5b is in contact with the front side of each of the opposing ceiling materials 1,1.

Note that the support member 9 is attached to the edges 2, 2 by appropriate means.
The support member 9 of this size may be made of offcuts such as ridges, C-shaped channel materials, etc., which are used as base materials for ceilings left at the construction site. When attaching the holder 4 to the support member 9, first loosen the screws 8 to separate the mounting bracket 7 and the overhanging member 5, and then insert the engaging bent portion of the mounting bracket 7 through the gap between the ceiling materials 1 and 1. After 7a is engaged with the support member 9, the screw 8 may be fastened.

Further, as shown in FIG. 2, it is preferable that the mounting bracket 7 is provided with a bending guide portion 7d that matches the size, height, and other dimensions of the support member 9. Such a guide portion may be formed as a long hole, a long groove, or the like.

Next, the cover material 3 is a long material wider than the overhanging member 5 of the holder 4, and has weather strips 10, 10 fitted to both ends, and a locking part (locking edge) in the center of the back side. ) 3a is formed, and the locking portion 3a is locked to the locking portion 6a of the holder 4.

When installing the expansion joint A with the above configuration, the cover material 3
The locking portion 3a of the holder 4 is pressed against the locking portion 6a of the holder 4, which is open between the ceiling materials 1, 1. However, when pushing up the cover material 3 and pressing its locking portion 3a against the locking portion 6a of the holder 4, both ceiling materials 1,
1 will be pushed up, and since the load is large, it will be difficult to lift up. Further, when the ceiling material 1 is relatively soft, the holder does not dig into the ceiling material due to tightening of the screws. Furthermore, when the cover material 3 is pushed up, the holder 4
Since the holder 4 is held so as not to retreat to the back side of the ceiling materials 1, 1, the holder 4 and the locking portions 6a, 3a of the cover material 3 can be easily and reliably engaged.

The cover material 3 in the expansion joint A configured as described above only contacts the opposing ceiling materials 1, 1, and the holder 4 is slidably provided on the ceiling materials 1, 1. ,earthquake,
Even if the building frame changes due to uneven settlement or the like and the ceiling materials 1, 1 are displaced, the holder 4 slides on the ceiling material 1 and absorbs the displacement, so the cover material 3 is always mounted stably. state can be maintained.

Next, the configuration of the holder 4 and the manner of engagement between the locking portion of the holder 4 and the locking portion of the cover material 3 are not limited to the above-mentioned example.

For example, as shown in FIG. 3, the holder 4 may have a projecting portion 5b and a locking portion 6a formed of the same member. In this case, the rib 11 is provided on the overhang portion 5b.
It is preferable to provide this to make it difficult to bend.

As for the locking portion of the holder 4, as shown in FIG. The locking portion 3a of the cover material 3 may be locked to the locking portion 12a,
Alternatively, as shown in FIG.
The shapes of the locking portion 3a of the cover member 3 and the locking portion 3a of the cover member 3 may be reversed.

Furthermore, as shown in FIG. 6, a spring 13 may be provided between the horizontal piece 7b of the mounting bracket 7 and the overhanging member 5. In this case, the mounting bracket 7 and the overhanging member 5 are separated from each other by the action of the spring 13, so that the mounting bracket 7 does not wobble, making the installation very easy.

In addition, as shown in FIG. 7, the holder 4 has locking portions 6a, 6a formed at both ends of the overhanging member 5, and locking portions 3a, 3a provided on both sides of the cover material 3. 6a and 3a may be secured and attached via a clip 12 having the same structure as the example shown in FIG. In this case, as shown in FIG.
The locking portion 6 (locking piece) of the cover material 3 is connected to the locking portion 3a of the cover material 3.
It may be configured to be elastically locked in the locking groove.

Furthermore, the holder 4 omits the mounting bracket 7 and directly connects the tip of the screw 7 inserted through the overhanging member to the supporting member 9.
The structure may be such that it is screwed into a screw receiving part (not shown) provided in the.

As described above, according to the cover material attachment device, the cover material 3 can be easily and reliably attached to the ceiling materials 1, 1.
