Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a fireproof partition wall, and more particularly to a stud provided at a connecting portion between wall panels.

[Prior Art] In recent years, partitioning of a building has been performed so that a partition of a required size can be obtained by a partition wall according to intended use after completion. As shown in FIG. 3, the partition wall is provided with a headboard 1 on the ceiling and a skirting board 2 on the floor, a wall panel 3 is fitted between the heading 1 and the skirting board 2, and further the wall panel 3 and the wall panel 3 are inserted. And are connected by studs 4.

The conventional stud has a structure as shown in FIG. 4 or 5.

First, referring to FIG. FIG. 6 is a view corresponding to the arrow AA in FIG. 3, and the same parts as those shown in FIG. 3 in FIG. 4 are designated by the same reference numerals.

The wall panel 3 is a heat-resistant plate 5 such as a calcium silicate plate covered with a surface plate 6 of a steel plate. The wall panels 3 and 3 are arranged with a required gap in the thickness direction of the wall, A non-combustible material 7 such as rock wool felt is filled in between.
A stud 4 is arranged at the joint between the wall panels 3 and 3, and the upper end of the stud 4 is fixed to the ceiling and the lower end thereof is fixed to the floor.

The stud 4 is composed of a stud main member 8 made of a refractory material such as calcium silicate in the shape of a square rod, a reinforcing metal member 9 attached from the front surface to the side surface of the main material 8 and a reinforcing metal member 9 attached from the back surface to the other side surface. And a stud cover 12 formed on both sides of the main pillar 11 and made of a refractory material such as calcium silicate.

The surface plate 6 of the wall panel 3 is bent so as to cover the end surface of the heat resistant plate 5, and a bent hook portion 13 is further formed along the reinforcing metal fitting 9. Reference numeral 14 is a joint plate for pushing in the hook portion 13, and the joint plate 14 is screwed to the reinforcing metal fitting 9 by a screw 15.
The joint plate 14 is covered with a joint cover 16.

Next, another conventional example shown in FIG. 5 will be described.

The stud main material 8 and two stud covers 12, 12 are combined in an H shape, and reinforcing metal fittings 17, 17 are provided along the front side and the back side of the stud main material 8 and the stud covers 12, 12, respectively. is there. Since the structure for fixing the surface plate 6 with the joint plate 14 or the like is as described above, the description thereof will be omitted.

[Problems to be Solved by the Invention] The conventional studs have been described with reference to FIGS. 4 and 5, but these conventional studs have the following problems.

Generally, in a partition wall that is required to have heat resistance, it is said that the portion having poor heat resistance is a connecting portion between the partition walls, that is, a stud. This is because the heat-resistant plate is discontinuous at the connection portion, and the thickness of the wall used for heat resistance is reduced due to the connection structure. Therefore, heat input from the stud portion must be sufficiently prevented. Further, since the stud is also a strength member of the connecting portion of the wall panels 3,3, sufficient strength and rigidity are required, and the reinforcing metal fittings 9,17 are required as described above.

Here, looking at the structure of the conventional stud shown in FIG. 4 and FIG. 5, the reinforcing metal fittings 9 and 17, both of which are made of metal, are formed on the front and back sides of the stud main material 8 and the stud cover 12 which are fireproof materials. The surface plate 6 and the joint plate 14 which are provided and have high heat are in direct contact (metal touch). For this reason, the reinforcing metal member 9 attracts heat to the inside of the wall panel 3 and serves as a heat source inside the wall panel 3, which causes an undesirable state in terms of heat shielding.

In view of such a situation, the present invention aims to more effectively shield the heat at the stud portion and further improve the fire resistance performance of the partition wall.

[Means for Solving the Problems] In the present invention, a pair of force bones, each of which is composed of a concave portion and side edges formed parallel to the concave bottom surface at both ends of the concave portion, are arranged so that the concave bottom surface is in close proximity, It is characterized in that the stud main members are respectively fitted and the stud covers are provided so as to extend over the side edge portions so that a space is formed in the central portion.

[Operation] The stud main material, which is a fire resistant material, faces the gap between the wall panels,
No metal contact between wall panel and stud. Moreover, since a space is formed inside the stud, the space serves as a heat insulating layer.
Therefore, heat input into the wall panel due to heat transfer is very effectively blocked.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, those having the same functions as those shown in the above-mentioned conventional example are designated by the same reference numerals.

Reference numeral 20 denotes a flat stud main material having a width sufficiently wider than the seam spacing of the wall panel 3, and the stud main material 20 is fitted and fixed in a recess formed toward the wall thickness center side of the force bone 21.
Further, a side edge portion 22 is formed at the end of the force bone 21 so as to be bent in parallel with the bottom surface of the recess. The stud main material 20 is provided so as to close the seams on the front and back of the wall panel 3, and
A stud cover 23 is provided so as to extend over the side edge portion 22, and the stud main members 20 and 20 and the stud covers 23 and 23 form a cross section having a space in the center. Thus, bicep 21
Forms a boundary between the stud main members 20 and 20 and the stud covers 23 and 23.

The upper and lower ends of the stud 4 configured as described above are fixed to the ceiling and floor via the fastening angle 24 formed in an L shape.

The edge of the surface plate 6 is pushed into the joint plate 14 as in the conventional example, but the screw 15 for fixing the joint plate 14 is used.
Is pierced through the stud main member 20 and screwed to the force bone 21.

Thus, according to the present embodiment, the force bone 21 made of metal is attached to the back surface of the stud main material 20 (the surface on the center side of the wall panel), and the gap between the wall panels 3 faces the refractory material. It is the stud main material 20 itself. Further, the surface plate 6 and the joint plate 14 are also in contact with the stud main member 20, there is no metal contact between the stud 4 and the wall panel 3, and there is no heat conduction due to contact between metals. Thus, the heat input from the gap of the wall panel 3 is completely shielded by the stud 4. In addition, heat conduction through the stud main material 20 and the force bone 21 is blocked in the central space, and further diffused by the stud main material 20 at the opposite position and the stud covers 23, 23 on the side. To be prevented. Further, since the strength bone 21 has a structure directly fixed to the stud main material 20 and the stud cover 23, the stud main material 20 and the stud cover 23
Reinforce together. In addition, the strength bone 21 is a fragile stud main material
Since it covers the corners of the stud cover 23 and the stud cover 23, handling is easy.

Next, a part of the stud-based refractory material is used as an inorganic foamed heat-insulating paint that uses an inorganic foamed heat-insulating paint that has an adhesive effect to fix the hard bones and the fire-resistant material such as the stud main material When replaced by, the heat insulating effect and heat shielding effect of the stud are remarkably improved by the heat insulating effect of the inorganic foamed heat insulating paint.

The following are examples of the inorganic foamed heat insulating paint 3.

Composition Silicon resin: 35-45% (weight) Sodium silicate: 35-45% (weight) Vinyl nitrate: 10-30% (weight) This inorganic foam insulation coating is liquid, so it is easy to handle. The studs are easy to make.

Thus, the wall thickness can be further reduced by using the inorganic foamed heat insulating paint.

If the inorganic foamed heat insulating paint is applied thickly and the heat resistant layer is formed with the inorganic foamed heat insulating paint, the stud main material and the like can be omitted.

[Advantage of the Invention] As described above, according to the present invention, there is no metal touch between the wall panel and the stud, and the heat transmission from the wall panel joint can be effectively shielded by the stud, and the partition wall The fireproof performance can be improved, the wall thickness of the partition wall can be thinned, and the space occupied by the partition wall can be reduced, so that the living space can be used effectively.

Further, if the inorganic foamed heat insulating paint is used for a part or all of the refractory material of the stud, the heat insulating effect is further improved, and the thickness of the partition wall can be further reduced.
