JP6829967B2 - Base panel and refractory wall with it - Google Patents

Description

The present invention relates to a refractory wall having fire resistance used for an outer wall or the like, and more particularly to a base panel serving as a base of the refractory wall.

Of course, the wall body used as the outer wall of the building is required to be strong and easy to handle, but in addition to this, it may be obliged to take fireproof measures.
In order to satisfy such fire resistance performance, an outer wall panel having a layered structure formed by stacking fire resistant materials such as gypsum board is used.

For example, in the outer wall described in Patent Document 1, a structural surface material, an exterior base material, a waterproof paper, a mortar layer, and a glass fiber are used with respect to the outer surface of the interior material formed by combining the underlay material and the upholstery material. Fire resistance is ensured by laminating nets and the like in the thickness direction.
Further, in the outer wall described in Patent Document 2, fire resistance is ensured by laminating phenol foam and a metal outer plate in the thickness direction on the outer surface of the wall body made of gypsum board.

Japanese Patent No. 5823268 Japanese Unexamined Patent Publication No. 2011-140834

However, in the techniques of Patent Document 1 and Patent Document 2, fire resistance is ensured in the entire outer wall provided with the above components, and it is necessary to obtain fire resistance certification again every time the exterior material is changed.
For this reason, there has been a demand for ensuring fire resistance and freedom of selection of exterior materials in the so-called "base panel" which is the basic part of the wall body.
That is, if sufficient fire resistance is ensured in the base panel, the base portion can bear the fire resistance, so that it is not necessary to depend on the exterior material disposed on the outer surface.
On the other hand, usually, in the outer wall, a plurality of plate materials are fastened to the vertical and horizontal furring strips, etc. to form one large wall body.
Therefore, a boundary portion (slight gap) is formed between the adjacent plate materials (butting portion).
Further, since the plate material used for the outer wall shrinks due to heat, when heated, the distance between the butt portions, which are the boundary portions, is widened.
The widening of the butt joints was a major factor in the deterioration of fire resistance.
For this reason, it is conceivable to stack the base materials in multiple layers, but there are problems that the thickness becomes large and that the workability deteriorates due to the large weight.

An object of the present invention is to solve each of the above problems, and to provide a base panel capable of maintaining high fire resistance performance and improving the degree of freedom in selecting an exterior material with a simple configuration and low cost. It is to provide a fireproof wall.
Another object of the present invention is to provide a base member capable of realizing high workability without increasing the thickness and weight, and a refractory wall provided with the base member.

According to the base panel according to the present invention, the above-mentioned problems constitute a base material for a wall of a building, and a frame-shaped frame body and a plurality of frames arranged so as to close the inner holes of the frame body. The upholstery material and a plurality of underlaying materials arranged so as to face each other through a predetermined gap in the frame body are provided, and between the upholstery material and the underlaying material. Is provided with a fire-resistant plate body, and the fire-resistant plate body is formed by at least one of the abutting portion of the adjacent upholstery material and the abutting portion of the adjacent underlaying material. A plurality of the fire-resistant plates are arranged at positions facing each other, and the fire-resistant plates adjacent to each other in the left-right direction, the fire-resistant plates adjacent to each other in the vertical direction, and the fire-resistant plates are arranged. The problem can be solved by disposing a fire-resistant material in the space surrounded by the underlaying material and the upholstery material .

Since it is configured in this way, the refractory plate body can be interposed between the upholstery material and the underlaying material, and the abutting portion between the upholstery material and the underlaying material is made of the fireproof plate body. Can be blocked.
It should be noted that the intent of the wording "arranged" in "a fire-resistant plate is arranged between the upholstery material and the underlaying material" is that the fire-resistant member is used. , The intention is that it does not necessarily have to be in close contact with both the upholstery and underlayment. That is, for example, it does not exclude a state in which the refractory plate is in close contact with the butt portion side of the upholstery material but not with the butt portion side of the underlayment material. ..
Since it is configured in this way, it is possible to improve the fire resistance performance by closing the butt portion, which is a factor that lowers the fire resistance performance.
By giving the base panel itself high fire resistance in this way, it is less necessary for the fire resistance to depend on the exterior material, and thus the degree of freedom in selecting the exterior material is increased.
Further, since the refractory plate body may be arranged at the position of the butt portion, the weight of the base panel can be reduced and the workability is improved.
Similarly, since it is not necessary to stack multiple layers of refractory plates, it is possible to prevent the base panel from increasing in thickness and improve workability.
The "upholstery material" referred to in the present invention refers to a constituent material arranged on the outdoor side (for example, a fireproof base material), and the "underlaying material" refers to a constituent material arranged on the indoor side (for example,). , Fireproof base material).

Further, specifically, at this time, it is preferable that the refractory plates are arranged in a grid pattern in the horizontal direction and the vertical direction.
Further, specifically, at this time, the refractory plate body is sandwiched in the gap between the upholstery material and the underlayment material, and is adjacent to the abutting portion of the adjacent upholstery material. The butt portion of the underlaying material faces the butt portion in the thickness direction, and the refractory plate body is formed on both the butt portion of the adjacent upholstery material and the butt portion of the adjacent underlaying material. It is preferable that they are arranged at facing positions.
As a specific application example, the refractory plate is preferably gypsum board.
As described above, in the present invention, as a more preferable embodiment, the refractory plate is sandwiched between the upholstery material and the underlayment material. Further, the number of required refractory plates can be reduced by facing the abutting portions of the upholstery material and the underlaying material in the thickness direction.
With such a configuration, the fire resistance performance of the base panel can be improved more easily and surely, which contributes to the weight reduction of the base panel.
Further, as the refractory plate, any plate having fire resistance can be used, and gypsum board, calcium silicate board, aluminum steel plate, rock wool board, glass wool board can be used. , Wood piece cement board and the like are exemplified.
However, if this refractory member is a gypsum board, it is suitable from the viewpoint of availability and the like.

At this time, as a specific application example, those having the refractory is air, the gap formed between the refractory plate body adjacent, it is preferable that is refractory space.
In the present invention, since the refractory plates need only be arranged at positions that close the butted portions, a space is formed between the refractory plates that are in the horizontal and vertical directions. Specifically, a space surrounded by an upholstery material, an underlaying material, and a refractory plate body that is adjacent to each other in the left-right direction and the up-down direction is formed.
Therefore, this space can be used as a space for arranging the fireproof member, which contributes to improving the fireproof performance of the base panel.
The refractory member arranged in the space in this way is not particularly limited and may be any one, and examples thereof include a rock wool board and a glass wool board.
However, as a preferable example, it is preferable to leave the space as it is and use the air existing in the place as a refractory member (those having fire resistance).
When configured in this way, the space becomes an air layer, but the thermal conductivity of the air is higher than that of gypsum board having a thickness equivalent to the depth of the space (the facing distance between the underlayment material and the upholstery material). Is about 10 times lower, and therefore, the space, which is an air layer, exhibits sufficient fire resistance.
With such a configuration, not only high fire resistance is ensured, but also the weight of the base panel does not increase by not inserting another member into the space, and the workability is improved. ..

Further, the refractory wall according to the present invention is arranged on the surface side of the base panel according to any one of claims 1 to 5 and the upholstery material on the side opposite to the side facing the underlayment material. It is configured to include the provided outer wall material.

According to the base panel according to the present invention, the refractory plate body can be interposed between the upholstery material and the underlaying material, and the abutting portion of the upholstery material and the underlaying material is made into the fire resistant plate body. Can be blocked.
In this way, the degree of freedom in selecting the exterior material can be increased by closing the butt portion, which is a factor that lowers the fire resistance performance, with the fire resistant plate-like body and giving the base panel itself high fire resistance performance. That is, when selecting the exterior material, the necessity of improving the fire resistance performance as one criterion is reduced, so that the range of selection of the exterior material is widened.
Further, the refractory plate body may be arranged at the position of the butt portion, so that the weight of the base panel can be reduced and the workability is improved.
Furthermore, since the space formed between the refractory plates can be used to improve the refractory performance, the existence of this space (particularly when the space is an air layer) can only reduce the weight and weight. It is possible to improve the fire resistance performance.
As described above, the base panel according to the present invention and the refractory wall using the same can maintain high fire resistance performance and improve the degree of freedom in selecting the exterior material with a simple configuration and low cost.
Further, in the base panel according to the present invention, high workability can be realized without increasing the thickness and weight.

<About the composition of the refractory wall>
The refractory wall S according to the present embodiment will be described with reference to FIGS. 1 and 2.
In the present embodiment, an example of a wall body constituting the outer wall will be described as the refractory wall S.
The refractory wall S according to the present embodiment includes a base panel 1 and an exterior material 2.
The base panel 1 includes an underlaying material 11, an upholstery material 12, a frame 13, and a refractory plate body 14.
The underlaying material 11 and the upholstery material 12 according to the present embodiment are so-called "fireproof base materials". In the present embodiment, the "underlaying material 11" refers to the fireproof base material arranged on the indoor side, and the "upholstery material 12" refers to the fireproof base material arranged on the outdoor side. To do.
In the present embodiment, one underlaying surface material is formed by arranging a plurality of rectangular underlaying members 11 in parallel, and similarly, a plurality of rectangular upholstery members 12 are arranged in parallel. As a result, one overlay surface material is constructed.

The frame 13 according to the present embodiment is a frame body assembled in a rectangular shape, and includes an upper frame 13A, a lower frame 13B, a vertical frame 13C, and a furring strip 13D.
The upper frame 13A and the lower frame 13B are long members (grooved steel with lips) made of lightweight steel frame having the same length and shape and having a substantially U-shaped cross section, and the vertical frame 13C is made of lightweight steel frame having a substantially U-shaped cross section. It is a long member of.

A rectangular frame-like body is formed by passing the vertical frames 13C and 13C between both ends of the upper frame 13A and both ends of the lower frame 13B, and between the left and right vertical frames 13C and 13C. A plurality of furring strips 13D, which are lightweight steel-framed members having a substantially U-shaped cross section (grooved steel with a lip), are arranged therein.
The furring strip 13D is passed between the upper frame 13A and the lower frame 13B so as to be parallel to the vertical frames 13C and 13C.
The configuration according to this embodiment is an example, and the number, arrangement, and the like of the furring strip 13D can be changed as appropriate.

The refractory plate 14 according to the present embodiment is a rectangular plate.
The fire-resistant plate body 14 may be any member such as gypsum board, calcium silicate board, aluminum steel plate, rock wool board, glass wool board, wood piece cement board, etc., as long as it has fire resistance performance. However, in the present embodiment, a gypsum board cut into a predetermined shape and a predetermined size is used.
In the present embodiment, a plurality of refractory plates 14 are used, and are sandwiched between the underlaying material 11 and the upholstery material 12.
The detailed arrangement of the refractory plate 14 will be described in detail later because it is the main configuration of the present embodiment.

The configuration of the base panel 1 according to the present embodiment is summarized above.
In the frame 13 assembled in the shape of a rectangular frame, the underlaying material 11 and the upholstery material 12 are arranged so as to close the inner hole portion surrounded by the frame.
A plurality of the underlaying material 11 and the upholstery material 12 are used, and by arranging the plurality of underlaying material 11 and the upholstery material 12 in parallel in the horizontal direction and the vertical direction, the inner hole portion in the frame 13 is provided. A rectangular underlaying surface material (face material arranged on the indoor side) and an upholstery surface material (face material arranged on the outdoor side) having an area sufficient to close the surface are formed.
A plurality of refractory plates 14 are sandwiched between the underlaying material 11 and the upholstery material 12.

The exterior material 2 according to the present embodiment is fixed to the outer surface of the overlay material 12 of the base panel 1 via the exterior material fastening metal fitting G1.
In this embodiment, a known ceramic siding is used.
As will be described later, in the present embodiment, the base panel 1 is provided with high fire resistance.
Therefore, high fire resistance is not always required for the exterior material 2.
That is, in the present embodiment, the degree of freedom of selection is high with respect to the material used as the exterior material 2.

<About the arrangement of refractory plates and refractory performance>
Next, the arrangement and the refractory performance of the refractory plate 14 will be described with reference to FIGS. 3 to 5.
As described above, in the present embodiment, the refractory plate body 14 is arranged in a state of being sandwiched between the underlaying material 11 and the upholstery material 12.
Further, as described above, a plurality of the underlaying material 11 and the upholstery material 12 are used, and these are used side by side in the horizontal direction and the vertical direction.
At this time, the underlaying member 11 and the upholstery member 12 are arranged in parallel so that the abutting portion T extends in a straight line in the vertical direction and the horizontal direction. That is, a plurality of underlaying members 11 and upholstery members 12 are arranged so as to form a grid pattern with the butt portion T as a boundary.
In the present embodiment, the boundary portion between the underlaying material 11 and the upholstering material 12 adjacent to each other in the vertical and horizontal directions is described as "butting portion T". The so-called "horizontal joints" and "vertical joints" in a broad sense, but the grooves formed between the adjacent exterior materials 2 are generally referred to as "horizontal joints" and "vertical joints", and this implementation is carried out. In the form, since the groove extending in the vertical direction is referred to as "vertical joint M" below, the word "butting portion T" is used to distinguish him. ..

The refractory plate body 14 according to the present embodiment is arranged so as to close the plurality of butt portions T. Specifically, as shown in FIG. 4, it is arranged so as to cover the butt portion T extending in a straight line in the vertical direction and the horizontal direction.
It should be noted that the width of the refractory plate 14 is sufficient to cover the butt portion T, and therefore, after the arrangement, the refractory plate 14 is arranged in a grid pattern as shown in FIG. .. In other words, there is no need for a large plate that covers the entire frame 13.
Therefore, the base panel 1 according to the present embodiment exhibits high fire resistance performance, does not increase its own weight, and also improves workability.

Further, since it is configured as described above, a space K1 is formed between the adjacent refractory plates 14.
In the present embodiment, there are a plurality of spaces K1 which are rectangular spaces surrounded by fire-resistant plate bodies 14 adjacent to each other in the left-right direction, fire-resistant plate bodies 14 adjacent to each other in the vertical direction, underlaying material 11, and upholstery material 12. It will be formed.
This space K1 is a wording intended to include a wide range of refractory members (in the present embodiment, it is sufficient that the space K1 has refractory performance, and for example, not only a standard object but also an amorphous substance or the like. Even if it exists, it is widely contained if it has fire resistance performance), and it is preferable that it is used as an arrangement space, for example, a rock wool board, a glass wool board, or the like is arranged.

However, in the present embodiment, as a suitable configuration, the space K1 is left as it is, and the air existing in the location is used as a refractory member (having fire resistance).
That is, the space K1 is an air layer, but the thermal conductivity of the air is about more than that of the gypsum board having a thickness equivalent to the depth of the space <the facing distance between the underlaying material 11 and the upholstery material 12>. It is 10 times lower, and therefore, the space K1 which is the air layer exhibits sufficient fire resistance performance.
Then, not only the fire resistance performance is ensured, but also the weight of the base panel 1 is not increased by not inserting another member at the relevant portion, and the workability is improved as described above.

As shown in FIGS. 2 and 3, the refractory plate 14 is a base material inserted from the outside of the upholstery 12 through the refractory plate 14 and the underlay 11 toward the furring strip 13D. It is fastened with the fixing screw V1.
Further, at the ends in the left-right direction, the base fixing screw V1 penetrates the refractory plate 14 from the outside of the overlay member 12 and penetrates the vertical frame 13C (the Z-shaped frame side metal fitting G2 attached to the vertical frame 13C). ) Is inserted and fastened. As a result, the vertical frame 13C portion has a two-layer structure, and the other portion (three-layer structure portion) has the underlaying material 11 dropped inside to increase the wall thickness of the refractory wall S. It is preventing.
Since the base fixing screw V1 is fastened through the fire resistant plate body 14, the fire resistant plate body 14 also functions as a screw support material for the base fixing screw V1.

Then, as shown in FIG. 5, the exterior material 2 is arranged on the base panel 1 according to the present embodiment, and is attached to the pillar H1.
The exterior material 2 is attached to the outer surface of the overlay material 12 by fastening the exterior material fixing screw V2 via the exterior material fastening metal fitting G1.
Further, a joint cap G3 having a hat-shaped cross section is arranged at the vertical joint M (a joint between the refractory walls S and S, which extends in a straight line in the vertical direction), and the vertical joint M is cut off from the outside. I'm protecting.

The base panel 1 configured as described above has sufficient fire resistance performance by itself.
This is because the base panel 1 has a layered structure and the refractory plate body 14 is interposed between the underlaying material 11 and the upholstery material 12, and the piece-shaped underlaying material 11 and the upholstery material 12 are used. The refractory plate 14 is arranged so as to close the butt portion T which is the seam, and the space K1 formed between the refractory plates 14 adjacent to each other in the vertical and horizontal directions is used to exhibit the refractory performance. This is the performance exhibited by what has been done (in this embodiment, the air layer has a low thermal conductivity).
As described above, since the base panel 1 according to the present embodiment itself has sufficient fire resistance performance, the fire resistance performance largely does not depend on the exterior material 2, and therefore, the degree of freedom in selecting the exterior material 2 is large. Become. Further, it becomes less necessary to worry about the deterioration of the fire resistance performance for each exterior material 2.
Further, since the structure is such a structure, it is possible to suppress the increase in weight and improve the workability regardless of the three-layer structure.

The air layer formed in the conventional example is not a space formed inside the base panel 1 (or a structure corresponding thereto), but a ventilation space formed outside the base panel 1.
That is, it is not a closed space formed in the base panel 1 as in the present embodiment, nor is it intended to exhibit fire resistance.
