Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireproof covering for a unit building, and more particularly, it can be used for covering a main structural material of a unit building with a fireproof material.

[0002]

BACKGROUND ART As shown in FIGS. 1 and 2, a unit building 4 is constructed by combining a plurality of building units, for example, first floor, second floor, and third floor building units 1, 2, and 3 at a construction site. Here, each building unit 1 and the like includes four pillars 10 at four corners and upper and lower beams 11 and 12 connecting upper ends and lower ends of the pillars 10 to each other.
A ceiling material, a floor material, a wall material 14 and the like are preliminarily attached to a skeleton 13 made up of in a factory to have a substantially box shape.

Among such unit buildings, three-story or more buildings for use in apartment houses, hospitals, hotels, etc., have main structures such as columns, beams, floors, walls, and roofs in accordance with the Building Standards Act. It is required that the part has a fireproof structure having a predetermined fireproof performance. Therefore, in general, the floor material, ceiling material and wall material are made of refractory material,
The roof is covered with a refractory material, and the pillars and beams are covered with a refractory material to meet the above requirement. Of these, the main structural materials that are adjacent to each other with a gap between adjacent building units are covered with a refractory material that extends over both of them, and as a refractory structure, asbestos cement as a refractory material that corresponds to the shape of the main structural material, etc. It is known that calcium silicate (silica plate) is directly attached to the main structural material by nailing etc. to cover it.

[0004]

However, conventionally, the silica plate is directly attached to the main structural member by nailing or the like. Since the plate of this main structural material is quite thick,
To drive a nail, you must drive it with a considerable force. When the nail is struck with a strong force by a hammer or the like, the calikal plate is driven too fast and the caikal plate is damaged as a result. In addition, when a nail or the like is hammered, it is possible to accidentally strike the calcareous plate without striking the nail or the like. In this case as well, the calical plate is still damaged.

Further, since the caulcal plate is attached to the main structural material by nailing or the like, the nail is placed at a predetermined position with one hand while pressing the caulcal plate against the main structural material.
It is necessary to hit the nail with another hand by using a hammer or the like, which is inconvenient and troublesome. In particular, it takes a lot of time because a single calcareous plate has to be nailed in many places. Furthermore, there is also the problem that careful driving of the calcareous plate requires careful work, which takes more time.

An object of the present invention is to provide a fireproof coating for a unit building, which can be easily installed in a short time without damaging the fireproof coating material on the adjacent main structural members with a gap between adjacent building units. To provide the ingredients.

[0007]

SUMMARY OF THE INVENTION Therefore, the present invention is a fireproof covering for a unit building, in which the main structural members adjacent to each other with a gap between the adjacent building units are covered with a fireproof material extending over the both, and The inner surface of the material is provided with a locking member that is formed of an elastic member and that can be locked by the repulsive force due to reduction when inserted in the gap, and the locking member is composed of a pair of locking pieces, The locking pieces constitute a fireproof covering of a building that spreads toward each other toward the gap and is tapered from the middle.

[0008]

According to the present invention as described above, the tip insertion portion and the locking portion of the fireproof covering are inserted into the gap between the adjacent building units of the unit building, and the attachment portions of the fireproof covering are adjacent to each other with a gap therebetween. Attach by straddling the same side of the structural material,
Refractory materials are attached to the main structural materials adjacent to each other with a gap between adjacent building units of the unit building. In this way, after inserting the tip insertion part and the locking part of the fireproof covering into the gap of the adjacent building unit, the locking part repels and prevents the falling out of the gap, so that the fireproof material is not damaged. In addition to being attachable, it is possible to easily attach in a short time, thereby achieving the above object.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, a unit building 4 such as a house in which the fireproof covering of the unit building of the present embodiment is used.
Is a three-story building as mentioned above. In order to make such a unit building 4 a fireproof structure, the outer wall 14, floor material and ceiling material (not shown) are made of fireproof material. A refractory material is attached to the pillars 10 and the upper and lower beams 11 and 12 at the four corners, which are main structural materials of each building unit 1 and the like. The calcareous plate is used as the refractory material.

3 and 4, a fireproof covering is attached to a pillar 10 which is a main structural material adjacent to each other with a gap between adjacent building units 3 and the like of the unit building 4, particularly a pillar 10 of an A portion in FIG. The refractory covering 100 is composed of the silica plate 101 and a locking member 102 fixed to the inner surface of the silica plate 101. Said calcareous plate
In 101, after the building units 3 and the like are combined and the outer walls 14 are attached to the columns 10 and 10, respectively, the outer walls 14 of the columns 10 and 10 are attached.
Is mounted across the surface opposite to the surface on which is attached.

The locking member 102 is attached to the inner surface of the silica plate 101, that is, the surface facing the two columns 10 as described above, as described above. The locking member 102 is formed to be slightly narrower than the width of the calcareous plate 101, and the pillar 10,
Mounting part 103 that abuts on the same side of 10, and this mounting part
A locking portion 104 is provided at the center of 103 and opposite to the surface of the calikal plate 101, the locking part 104 being provided orthogonally to the calikal plate 101.

The locking portion 104 is formed of an elastic member such as spring steel, and is formed by arranging a pair of locking pieces having a V-shaped cross section so as to bulge at the center. The tip end of each of the pair of locking pieces is a tip insertion part 104A that can be inserted into the gap between the columns 10 and 10, and the bulging part 10 having a V-shaped cross section.
4B is a locking portion which is formed to have a width larger than that of the gap and which shrinks when being inserted into the gap and which is prevented from falling out of the gap by a repulsive force generated by the reduction.

Further, projections 10A are fixed to the facing surfaces of the columns 10 and 10 so as to project outward from the outer surface of the column 10, that is, to approach each other. This protrusion 10A has an inclined side that follows the shape of the locking portion 104, and both are more firmly engaged, and to release the engagement, the elastic force of the locking portion 104 does not force the pull. Locking member 102,
In other words, it is difficult for the fireproof covering 100 to come off the columns 10 and 10.

As shown in FIG. 3, the outer side surfaces of the two same side surfaces of the pillars 10 and 10 to which the fireproof covering 100 is attached and the other two side surfaces to which the outer walls 14 and 14 are attached are as shown in FIG. Other fireproof coverings 107, each of which is composed of a silica plate 105 having a width covering the side surface of one pillar 10 and a mounting member 106 fixed to the inner surface thereof, are mounted. The fireproof covering 107 and the fireproof covering 100 are connected to each other by the nails 108 and the like after they are mounted on the columns 10 and 10.

Next, the operation of this embodiment will be described. After combining a plurality of building units 3 etc. at the construction site, outer walls 14, 14 are attached to the outer sides of adjacent columns 10, 10 of adjacent building units 3, etc. with a gap, and the outer walls 14, 10 of the columns 10, 10 are attached. The fireproof covering 107 is attached to the surface orthogonal to 14.

Next, a locking member 102 is attached to the side surface of the adjacent pillars 10 and 10 opposite to the outer walls 14 and 14 so that the locking portion 104 faces the outer walls 14 and 14. That is, the tip insertion portion 104A of
And the bulging portion 104B are inserted toward the gaps between the columns 10,10. When the bulging portion 104B goes over the protrusion 10A, the bulging portion 104B is contracted and deformed, but the mounting portion 103 is pushed until it comes into close contact with the same side surface of the columns 10,10. The bulging portion 104B has a repulsive force generated by the contracting deformation, which causes the silica plate 101 to move to the pillars 10,1.
Hold in the space between 0s. After that, both fireproof coatings 100, 10
Connect 7 with nails 108 etc.

According to this embodiment as described above, the following effects can be obtained. That is, the calikal plate 101 includes the tip insertion portion 104A and the bulging portion 10A of the locking member 102 attached to the inner surface thereof.
Adjacent pillars such as building units 3 that are adjacent to 4B with a gap
If it is inserted into the gap between 10 and 10, it is locked to the columns 10 and 10 by the repulsive force generated by the contraction deformation of the bulged portion 104B, so that it can be attached without nailing or the like. Therefore,
It can be mounted between the adjacent pillars 10 and 10 of the building unit 3 and the like adjacent to each other with a gap therebetween without damaging the calcareous plate 101.

Further, as described above, the caulking plate 101 can be mounted only by inserting the tip insertion portion 104A and the bulging portion 104B of the locking member 102 into the gaps between the adjacent columns 10 and 10, so that it can be carried out for a short time. Can be done easily. Further, projections 10A are fixed to the facing surfaces of the columns 10 and 10, respectively, and the projections 10A have inclined sides that follow the shape of the locking portion 104, and both are more firmly engaged. To release the engagement between the two, the locking part 10
It must be pulled by a force exceeding the elastic force of 4, and therefore, the locking member 102, that is, the fireproof covering 100 is also difficult to pull out from the columns 10 and 10.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but includes the following modifications. That is, although the engaging portion 104 of the above-described embodiment is formed by the tip insertion portion 104A and the bulging portion 104B having a substantially V-shaped cross section, the invention is not limited to this. The pillars may be provided so that their central portions bulge with each other, and the side surfaces of the columns 10, 10 may be stretched and locked at the central portions.

In the above embodiment, the fireproof covering 100 is mounted between the adjacent columns 10 and 10 of the building units 3 and the like adjacent to each other with a gap between the unit buildings 4, but the present invention is not limited to this. Is sufficient if there is a main structural material that separates the gaps in the building units 3 and the like that are adjacent to each other with a gap therebetween.
It may be used between 11 or lower beams 12.

In addition, the specific structure, shape, and the like for carrying out the present invention may be any other structure as long as the object of the present invention can be achieved.
