TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a structure for attaching a fireproof surface material such as a gypsum board to a wall surface of a building such as a house.
[0002]
[Background technology]
A fire-resistant surface material usually made of gypsum board or the like is attached to the wall surface of a building such as a house. In order to further improve the fire resistance, the fire-resistant surface material may be double-attached. An example of this technique is described in Patent Document 1, for example.

[Problems to be solved by the invention]
By the way, as described above, when two fire-resistant face materials such as a gypsum board are mounted on a wall surface, it is desirable that the seam of the upper fire-resistant face material is as small as possible. This is because, in terms of fire prevention performance, the smaller the number of joints is, the less the faults in fire prevention become, and the more effective it becomes. In addition, since a cloth is finally attached to the surface of the upper refractory surface material, at the joint between the refractory surface materials, a streak or the like along the seam is easily formed in the cross, so that the streak does not enter the cross. This is not only because it takes time and effort to attach it, but sometimes the cross cuts along the seam, and it takes time to repair it.
In order to minimize the number of joints between the upper refractory surface materials, the upper refractory surface material may be increased. However, when the upper refractory surface material is increased, the weight of the upper refractory surface material increases, making it difficult to handle.
On the other hand, if the upper refractory surface material is thinned so as not to increase in weight, the total thickness of the upper refractory surface material and the lower refractory surface material is reduced, and the fire resistance performance is reduced.
Therefore, by increasing the thickness of the lower refractory surface material, the total thickness of the upper refractory surface material and the lower refractory surface material can be made a predetermined thickness, but the weight of the lower refractory surface material is reduced. Becomes bulky and difficult to handle.
[0005]
The present invention has been made in view of the above circumstances, and in a case where two refractory face materials are attached to a wall surface, the number of joints between the upper refractory face materials can be reduced, and the weight increase of the upper refractory face material is suppressed. Further, the total thickness of the upper refractory surface material and the lower refractory surface material can be set to a predetermined thickness, and the weight of the lower refractory surface material can be reduced. It is intended to provide a mounting structure.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is, for example, as shown in FIGS. 1 to 5, a structure for mounting a fireproof surface material on a wall surface,
A plurality of square plate-shaped lower refractory surface materials 3 are attached to the wall surface, and at least one or more square plate-like upper surfaces are formed on an attachment surface 5 formed by the lower refractory surface materials 3. Fireproof material 4 is attached,
The upper refractory surface material 4 is characterized by being thinner and larger in area than the lower refractory surface material 3.
[0007]
Here, in the case where the fire-resistant surface material is double-attached and attached to the wall surface, the two fire-resistant surface materials need to have a predetermined thickness in order to obtain a predetermined fire resistance performance. In the present invention, the predetermined thickness may be secured by increasing the thickness of the lower refractory surface material 3 by the thickness of the upper refractory surface material 4.
[0008]
According to the first aspect of the present invention, since the upper refractory surface material 4 is thinner and has a larger area than the lower refractory surface material 3, the number of joints between the upper refractory surface materials 4 can be reduced, and the upper refractory surface material can be reduced. The bulk of the material 4 can be suppressed. Further, by making the lower refractory surface material 3 thicker by the thickness of the upper refractory surface material 4, the total thickness of the upper refractory surface material 4 and the lower refractory surface material 3 can be made a predetermined thickness. Furthermore, since the area of the lower refractory surface material 3 is smaller than that of the upper refractory surface material 4, the weight of the lower refractory surface material 3 can be reduced.
[0009]
According to a second aspect of the present invention, in the structure for mounting a fireproof surface material according to the first aspect,
The lower refractory surface material 3 and the upper refractory surface material 4 are connected to the joints T1 and T2 of the lower refractory surface materials 3 and 3 adjacent to each other and the joint of the upper refractory surface materials 4 and 4 adjacent to each other. It is characterized by being arranged such that T3 does not match.
[0010]
According to the invention described in claim 2, the joints T1 and T2 of the lower refractory face materials 3 and 3 adjacent to each other do not match the joint T3 of the upper refractory face materials 4 and 4 adjacent to each other. The joint T3 between the upper refractory face materials 4, 4 is located on the lower refractory face material 3, so that the adjacent upper refractory face materials 4, 4 are less likely to have a step near the joint T3. Become. Therefore, when the cloth is stuck on the upper refractory surface material 4, it is possible to solve the problem that the cloth is scratched or ridged along the seam T <b> 3 or the cloth is cut.
[0011]
According to a third aspect of the present invention, in the mounting structure for a fireproof surface material according to the second aspect,
One of the lower refractory surface material 3 and the upper refractory surface material 4 has a horizontally long rectangular plate shape, and the other has a vertically long rectangular plate shape,
The lower refractory surface material 3 and the upper refractory surface material 4 are arranged such that their long sides are orthogonal to each other.
[0012]
According to the third aspect of the present invention, since the long sides of the lower refractory face material 3 and the upper refractory face material 4 are orthogonal to each other, a joint T2 between the lower refractory face materials 3, 3 is provided. The seam T3 of the upper refractory surface materials 4, 4 is orthogonal to the upper surface. Since the seams T2 and T3 are orthogonal to each other without facing in the same direction, it is possible to prevent a decrease in strength when the seams overlap.
[0013]
According to a fourth aspect of the present invention, in the mounting structure for a fireproof surface material according to the third aspect,
The lower fire-resistant face material 3 has a horizontally elongated rectangular plate shape, and the upper fire-resistant face material 4 has a vertically elongated rectangular plate shape,
The length of the long side of the lower refractory surface material 3 and the length of the short side of the upper refractory surface material 4 are each an integral multiple of the reference dimension.
[0014]
Here, it is desirable that the reference dimension is set to a reference dimension when all parts of the building are to be arranged in a multiple of a certain size. In this case, for example, 910 mm, 455 mm, 1000 mm, 500 mm, etc. are adopted as the reference dimensions.
[0015]
According to the invention as set forth in claim 4, the total extension of the lower refractory face material 3 arranged in the lateral direction via the seam T1 is an integral multiple of the reference dimension, and is arranged in the lateral direction via the seam T3. Since the total extension of the upper refractory surface material 4 is an integral multiple of the reference size, the lateral length of the wall surface on which the lower refractory surface material 3 and the upper refractory surface material 4 are attached is set to an integral multiple of the reference size. By setting, the lower refractory surface material 3 and the upper refractory surface material 4 can be laterally allocated to the wall surface without any gap.
[0016]
According to a fifth aspect of the present invention, in the structure for mounting a fireproof surface material according to the fourth aspect,
The lower refractory surface material 3 is characterized in that seams T1 between short sides are arranged so as not to be continuous in the vertical direction.
[0017]
According to the fifth aspect of the present invention, since the joints T1 between the short sides of the lower refractory surface material 3 are not continuous in the vertical direction, the mounting surface 5 formed by these lower refractory surface materials 3 , As compared to the case where the seam T1 is continuous in the vertical direction. Therefore, the upper refractory surface materials 4 attached to the attachment surface 5 are less likely to have a step near the joint T3. Therefore, when a cloth is stuck on the upper refractory surface material 4, problems such as scratches and ridges on the cloth along the seam and breakage of the cloth can be solved.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the mounting structure of the fire-resistant face material according to the present embodiment, as shown in FIG. 5, the lower fire-resistant face material and the upper face are attached to the wall surface of the partition wall 2 formed by joining a plurality of partition panels 1 in the lateral direction. A description will be given of a case where a refractory surface material is attached as an example.
[0019]
The partition panel 1 is a skeleton panel formed by assembling a frame member 1a into a rectangular frame shape and assembling a reinforcing bar 1b inside the rectangular frame, and joining a plurality of such partition panels 1 in a lateral direction. Thereby, the partition wall 2 is formed.
In addition, the width dimension of the partition panel 1, that is, the length in the horizontal direction is set to, for example, 1M when the reference dimension is, for example, 910 mm and this is 1M (module). Then, by joining a plurality of partition panels 1 having a width of 1M, a partition wall 2 having a width of an integral multiple of 1M is formed.
[0020]
As shown in FIG. 2, a lower refractory surface material 3 and an upper refractory surface material 4 are attached to both surfaces of the partition wall 2, respectively.
As shown in FIG. 1 and FIG. 3, the lower refractory surface material 3 has a horizontally long rectangular plate shape, and is formed of a reinforced gypsum board. The length of the lower refractory surface material 3 in the horizontal direction, that is, the length of the long side is set to 2M (module), and the thickness is set to about 21 mm.
As shown in FIG. 1 and FIG. 4, the upper refractory surface material 4 has a vertically long rectangular plate shape, and is formed of a reinforced gypsum board. The length of the upper refractory surface material 4 in the horizontal direction, that is, the length of the short side is set to 1M (module), and the thickness is set to 15 mm.
When the length of the lower refractory surface material 3 in the vertical direction, that is, the length of the short side is L, the length of the upper refractory surface material 4 in the vertical direction, that is, the length of the long side is set to 5L. I have.
Thus, the upper refractory surface material 4 is thinner and larger in area than the lower refractory surface material.
[0021]
The lower refractory surface material 3 and the upper refractory surface material 4 as described above are arranged and attached to the wall surface of the partition wall 2 as described below.
That is, as shown in FIG. 3, a large number of lower refractory surface materials 3 are attached to the wall surface of the partition wall 2 by gluing or nailing. The lower refractory surface material 3 is arranged in five stages in the vertical direction (vertical direction in the figure), and a predetermined number in the horizontal direction, that is, the number corresponding to the horizontal length of the wall surface. The vertical height of the partition wall 2 is set to 5 L. Therefore, the length of the lower side refractory surface material 3 whose short side is L is arranged in five stages in the vertical direction, so that the wall surface of the partition wall 2 is formed. It fits without gap from the upper end to the lower end.
Further, the lower refractory surface materials 3, 3 vertically adjacent to each other are arranged such that the end of one lower refractory surface material 3 is located at the center of the other lower refractory surface material 3. . As a result, the joints T1 between the lower refractory surface materials 3 and 3 adjacent to each other in the horizontal direction (the left and right direction in the figure) are not continuous in the vertical direction but are arranged in a staggered manner. In addition, the seam T2 between the lower refractory surface materials 3, 3 vertically adjacent to each other is continuous in the horizontal direction.
[0022]
A large number of upper refractory surfaces 4 are attached to the mounting surface 5 formed by the multiple lower refractory surfaces 3 by bonding or nailing. As shown in FIG. 4, the upper refractory surface material 4 has a vertical length, that is, a long side length of 5L and a wall height of 5L. Are arranged in a predetermined number in the horizontal direction, that is, the number corresponding to the length of the wall surface in the horizontal direction. Moreover, as shown in FIG. 1, the lower refractory surface material 3 and the upper refractory surface material 4 are arranged such that their long sides are orthogonal to each other.
Further, the seam T3 between the upper refractory face materials 4, 4 adjacent in the lateral direction (the left-right direction in the figure) is arranged so that the position does not coincide with the seam T1 between the lower refractory face materials 3, 3. I have. That is, the joint T3 is arranged at a position shifted in the horizontal direction by the distance s from the joint T2. This distance s is set to １ ／ of the length of the long side of the lower refractory surface material 3, that is, 0.5 M (module).
As described above, the lower refractory surface material 3 and the upper refractory surface material 4 are formed by the joints T1 and T2 of the lower refractory surface materials 3 and 3 adjacent to each other and the upper refractory surface materials 4 and 4 adjacent to each other. It is arranged so that the seam T3 does not match.
[0023]
As shown in FIG. 5, the mounting structure of the refractory surface material according to the present embodiment forms a partition wall 2 by joining a predetermined number of the partition panels 1 in the lateral direction, and forms the partition wall 2. First, a large number of lower refractory surface materials 3 are attached to the surface, and then a large number of upper refractory surface materials 4 are attached to a mounting surface 5 formed by the lower refractory surface materials 3. After the upper refractory surface material 4 is attached, a partition is finished by attaching a cloth on the upper refractory surface material 4.
[0024]
According to the present embodiment, the following effects can be obtained.
Since the upper refractory face material 4 is thinner and has a larger area than the lower refractory face material 3, the joint T3 between the upper refractory face materials 4 and 4 can be reduced, and the weight of the upper refractory face material 4 is suppressed from increasing. be able to. Further, by making the lower refractory surface material 3 thicker by the thickness of the upper refractory surface material 4, the total thickness of the upper refractory surface material 4 and the lower refractory surface material 3 can be made a predetermined thickness. Furthermore, since the area of the lower refractory surface material 3 is smaller than that of the upper refractory surface material 4, the weight of the lower refractory surface material 4 can be reduced.
[0025]
Since the seam T1 between the lower refractory surface materials 3 and 3 adjacent to each other does not match the seam T3 between the upper refractory surface materials 4 and 4 adjacent to each other, the seam T3 between the upper refractory surface materials 4 and 4 is: Since it is located on the lower refractory face material 3, the adjacent upper refractory face materials 4, 4 are less likely to have a step near the joint T3. Therefore, when the cloth is stuck on the upper refractory surface material 4, it is possible to solve the problem that the cloth is scratched or ridged along the seam T <b> 3 or the cloth is cut.
[0026]
Since the long sides of the lower refractory face material 3 and the upper refractory face material 4 are orthogonal to each other, a joint T2 between the lower refractory face materials 3, 3 and a joint between the upper refractory face materials 4, 4 are provided. T3 is orthogonal. Since the seams T2 and T3 are orthogonal to each other without facing in the same direction, it is possible to prevent a decrease in strength when the seams overlap.
[0027]
Since the lower refractory surface material 3 having a lateral length of 2M (Module) is laterally arranged on the wall surface of the partition wall 2 having a width dimension of an integral multiple of 1M (Module) via the seam T1, the lower The total extension of the side refractory surface material 3 can be made equal to an integral multiple of the reference dimension, that is, equal to the lateral length of the wall surface, and the upper refractory surface material 4 having a lateral length of 1 M (module) is jointed in the lateral direction. Since it is arranged via T3, the total extension of the upper refractory surface material 4 can be made equal to an integral multiple of the reference dimension, that is, equal to the lateral length of the wall surface. Therefore, the lower refractory surface material 3 and the upper refractory surface material 4 can be laterally allocated to the wall surface without any gap. In addition, among the lower refractory surface materials 3 attached to the wall surface, those located at the end of the wall surface may be appropriately cut in accordance with the end.
[0028]
Since the joints T1 between the short sides of the lower refractory surface materials 3 and 3 are not continuous in the vertical direction, the mounting surface 5 formed by the lower refractory surface materials 3 and 3 has a seam that is continuous in the vertical direction. As a result, the entire surface becomes flat.
Therefore, a step is less likely to occur between the upper refractory surface materials 4 and 4 attached to the attachment surface 5 near the joint T3. Therefore, when the cloth is stuck on the upper refractory surface material 4, it is possible to solve the problem that the cloth is scratched or ridged along the seam T <b> 3 or the cloth is cut.
[0029]
In the present embodiment, the lower refractory surface material 3 and the upper refractory surface material 4 are arranged as shown in FIG. 1 to form a joint T1 between the lower refractory surface materials 3 and 3 adjacent to each other. And the seam T3 between the upper refractory face materials 4 and 4 adjacent to each other is not matched, but the arrangement of the lower refractory face material 3 and the upper refractory face material 4 is not limited to that shown in FIG. For example, the lower refractory surface material 3 and the upper refractory surface material 4 may be slightly shifted left and right from the position shown in FIG. In short, the lower refractory surface material 3 and the upper refractory surface material 4 may be arranged such that the seams T1 and T3 do not coincide with each other.
[0030]
Further, in the present embodiment, the case where the lower refractory surface material 3 and the upper refractory surface material 4 are attached to the wall surface of the partition wall 2 formed by joining a plurality of the partition panels 1 has been described. The wall surface on which the material 3 and the upper refractory surface material 4 are mounted may be a wall surface formed by a conventional framing method or a two-by-four method that does not depend on a panel, and is not limited to a partition wall, and may be an outer wall or other load-bearing wall. It may be a wall.
Further, in the present embodiment, the partition wall 2 is formed by the partition panel 1, and then the lower refractory surface material 3 and the upper refractory surface material 4 are attached to the wall surface of the partition wall 2. The lower refractory surface material 3 and the upper refractory surface material 4 are previously attached to itself, and the present invention can also be applied to a structure in which these are joined on site.
[0031]
【The invention's effect】
As described above, according to the first aspect of the present invention, since the upper refractory surface material is thinner and has a larger area than the lower refractory surface material, the number of seams between the upper refractory surface materials can be reduced, and the upper refractory surface material can be reduced. The bulk of the face material can be suppressed, the total thickness of the upper and lower fire-resistant face materials can be made a predetermined thickness, and the weight of the lower fire-resistant face material can be further increased. Can be suppressed.
[0032]
According to the second aspect of the present invention, the seam between the lower refractory surface materials and the seam between the upper refractory surface materials do not coincide with each other, so that a step occurs near the seam between the adjacent upper refractory surface materials. It becomes difficult. Therefore, when attaching the cloth on the upper fire-resistant surface material, it is possible to solve the problem that the cloth is scratched or ridged along the seam or the cloth is cut.
[0033]
According to the third aspect of the present invention, since the joint between the lower refractory surface materials and the joint between the upper refractory surface materials are orthogonal to each other, it is possible to prevent a decrease in strength when the joints overlap.
[0034]
According to the fourth aspect of the present invention, the length of the long side of the lower refractory surface material and the length of the short side of the upper refractory surface material are each integral multiples of the reference dimension. By setting the horizontal length of the wall where the refractory surface material and the upper refractory surface material are to be installed to an integral multiple of the reference dimension, the lower refractory surface material and the upper refractory surface material can be separated laterally on the wall without gaps. Can be assigned.
[0035]
According to the fifth aspect of the present invention, since the joints between the short sides of the lower refractory surface material are not continuous in the longitudinal direction, a step is less likely to occur between the upper refractory surface materials near the joint. Therefore, when attaching a cloth on these upper refractory surface materials, it is possible to solve the problem that the cloth is scratched or ridged along the seam or the cloth is cut.
