Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireproof structure of a building unit, and in particular, it can be used when a plurality of building units are combined to construct a unit building.

[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, for three-story or more buildings for use in apartment houses, hospitals, hotels, etc., the main structures such as columns, beams, floors, walls, roofs, etc., 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. Among them, as a conventional fire-resistant structure in which the outer wall is attached to the inner two surfaces of the four corner columns of the building unit, that is, the conventional fire resistant structure in the corner of the building unit, asbestos cement as a fire resistant material corresponding to the shape of the pillar is used. It is known that calcium silicate (silica plate) is directly attached to the two surfaces of the column where the outer wall is not attached by nailing or the like to cover them.

[0004]

However, conventionally, the silica plate is directly attached to the column by nailing or the like.
Since the plate of this pillar is quite thick, it must be driven with considerable force to drive a nail. 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 pillar by nailing or the like, the nail is placed at a predetermined position with one hand while pressing the caulcal plate against the pillar, and the hammer or the like is held with another hand. It is necessary to hold the nail and hit it, 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. Another problem is that it requires careful work to hit the calik board without breaking it, which would take more time.

An object of the present invention is to provide a fireproof structure for a building unit, which can be easily installed in a short time without damaging the fireproof material on the two outer surfaces of the pillars of the building unit which are orthogonal to each other. To provide.

[0007]

Therefore, the present invention provides a fireproof structure of a building unit in which two outer surfaces of pillars of the building unit that are orthogonal to each other are covered with a fireproof material, and an inner surface of each of the fireproof materials is provided. Is a mounting member formed of an elastic member and capable of expanding when mounted on the column, and the mounting members are vertically displaced from each other. The mounting member includes a contact portion that contacts one side surface of the column and the contact portion. A locking portion formed at one end of the contact portion so as to be bent at a substantially right angle and abutting on one side surface orthogonal to the one side surface, and a locking portion formed at the other end of the contact portion so as to abut on the other side surface orthogonal to the one side surface. Fire resistance of a building unit that is formed in the same direction as the stop part and from the base end part to the middle part toward the locking part side and flips from there to bend the guide part to elastically clamp the column with the locking part It is structured

[0008]

According to the present invention as described above, in order to coat the two outer surfaces of the building unit, which are orthogonal to each other, with the refractory material, the mounting member is attached to the inner surface of the refractory material, and the contact portion is one of the pillars. The side surface is contacted, the locking portion is brought into contact with one side surface orthogonal to one side surface of the column, and the bending guide portion is brought into contact with the other side surface opposite to the one side surface of the column, thereby the locking portion. The column is elastically clamped between and the bending guide part. In order to attach refractory material to the two outer surfaces of the pillar of the building unit that are orthogonal to each other, the pillar is elastically sandwiched between the locking portion of the mounting member and the bending guide portion, and the contact portion is provided on one side surface of the pillar. It only needs to be brought into contact, and it can be attached without damaging the refractory material, and can be easily attached in a short time.

There is. The refractory covering 100 is composed of the silica plate 101 and a mounting member 102 fixed to the inner surface of the silica plate 101.

The silica plate 101 has two outer surfaces of the pillar 10 which are orthogonal to each other, that is, an outer wall 14 and a corner outer wall 14A.
It is made up of two sheets, a first silica plate 21A and a second silica plate 21B, which cover the two surfaces not covered by and. The second silica plate 21B has a width substantially the same as the width of the pillar 10, The plate 21A is formed slightly wider than the second calcareous plate 21B.

A plurality of mounting members 102, 102 are mounted on the inner surface of each of the calcareous plates 21A, 21B, that is, the surface facing the pillar 10, and these mounting members 102 are attached to one side surface of the pillar 10. A contact portion 20A which is in contact with the contact portion 20A, a locking portion 20B which is formed at one end of the contact portion 20A at a substantially right angle and abuts on one side surface orthogonal to the one side surface, and at the other end of the contact portion 20A. A bending guide portion 20D having a V-shaped cross section, which is in contact with the other side surface orthogonal to the one side surface, is in the same direction as the locking portion 20B, and extends from the base end portion 20C to an intermediate position toward the locking portion 20B side and is inverted from there. And is configured.

Mounting members 102, 10 for the respective calcareous plates 21A, 21B
They are mounted one above the other to prevent them from interfering with each other. Further, such a mounting member 20 is formed of an elastic member such as spring steel.

Next, the operation of this embodiment will be described. A plurality of building units 3 etc. are produced in advance in a factory. In addition, in the factory, the fixture 102 is fixed to the calcareous plate 101 in advance and is attached to the pillar 10 of the corner of the building unit 3 or the like.
To create.

After a plurality of building units 3 etc. are brought into a construction site and these are combined appropriately to build a unit building 4, a fireproof covering 100 is attached to the pillars 10 at the corners of the building units 3 etc. . That is, in order to mount the fireproof covering 100 on the corner pillar 10 of the building unit 3 or the like, while inserting the bending guide portion 20C into the gap between the outer wall 14 and the pillar 10, the locking portion 20B is used to fit the gap of the pillar 10 mentioned above. Insert the opposite side, contact part
Push in the calcareous plate 101 until the 20A contacts one side of the pillar 10. In this manner, the two surfaces of the corner pillar 10 are covered with the silica plate 101.

According to this embodiment as described above, there are the following effects. That is, when the mounting member 102 is pressed against the pillar 10, the caulking plate 101 can be mounted by connecting the pillar 10 or the beam 1 with the engaging portion 20B or the like formed of spring steel or the like and the bending guide portion 20C or the like.
Since 1 and 12 are sandwiched and locked, it does not need to be nailed. Therefore, it is possible to mount the keical plate 101 on the pillar 10 and the beams 11 and 12 without damaging it.

The mounting of the calikal plate 101 may be performed by pressing the mounting member 102 against the column 10 as described above, and sandwiching the column 10 and the beams 11 and 12 between the locking portion 20B and the bending guide portion 20C. Therefore, it can be easily performed in a short time.

Further, the tip of the bending guide portion 20C, etc. is a pillar.
Since it has a shape that opens outward in the direction away from the surface of the pillar 10 etc., with the part that abuts 10 etc. as the base point,
When the 102 is attached to the pillar 10 or the beams 11 and 12, it is easy and smooth.

The present invention is not limited to the above-mentioned embodiments, but includes the following modifications and the like. That is, when the caulking plate 101 is mounted on the corner pillar 10 of the above-described embodiment, the mounting member 102 is a bending guide portion.
I tried to insert 20C into the gap between the pillar 10 and the outer wall 14,
Not limited to this, the locking portion 20B may be inserted into this gap. The point is that the column 10 can be sandwiched between the bending guide portion 20C and the locking portion 20B.

Further, the shape of the bending guide portion 20C in the above-mentioned embodiment is substantially V-shaped in cross section, but the shape is not limited to this, and the bending guide portion 20C may be formed at, for example, the corner portion of the column 10. The base end portion 20D of 20C may have a semicircular shape in which the other end is in contact with the pillar 10 and a semicircular tip having a small diameter extending outward from the pillar. The point is that the bending guide section 20C
It suffices if the column 10 can be held by the elastic force between the locking portion 20B and the locking portion 20B.
