Description

The present invention relates to a reinforcing material for a fireproof panel and a fireproof panel using the reinforcing material.

Conventionally, a fireproof panel having a sandwich structure in which surface materials (panels) such as steel materials are arranged on the front and back surfaces and a nonflammable heat insulating material such as rock wool is sandwiched between these surface materials has been known. Such a refractory panel has a small space inside, but by arranging a heat insulating material having a certain density or higher between the panels, heat from the heated surface material to the surface material on the opposite side is mediated by air. It is possible to limit the movement of the air and improve the fire resistance effect (see Patent Document 1).

However, in the conventional refractory panel, when a plurality of refractory panels are fitted and combined to form a refractory panel unit, heat easily enters from a gap between the panels at a fitting portion which is a joint of the plurality of refractory panels. Therefore, when the refractory panel is heated for a certain period of time or longer in the vicinity of the fitting portion, the edges of the refractory panel may easily warp outward. Then, when the end portion of the refractory panel warps outward, a larger gap is created in the vicinity of the fitting portion, and heat easily enters. In addition, the gap inside the heat insulating material sandwiched between the panels is widened in the vicinity of the fitting portion, and the heat insulating property of the heat insulating material is lowered. For this reason, there has been a problem that the initial noncombustible performance and heat insulating performance of the refractory panel are deteriorated.

The present invention solves the above-mentioned problems of the conventional refractory panel, prevents the space between the surface materials of the refractory panel from widening, and makes it difficult for the nonflammable performance and the heat insulating performance to deteriorate even when heated above a certain level.

Both the front side surface material 20 and the back side surface material 30 are formed to have a length of about 1000 mm, a width of about 3000 mm, and a thickness of about 0.5 mm, but these can be changed in various ways, and various dimensions are limited. No. In this example, the front surface material 20 is arranged on the outdoor side, and the back surface material 30 is arranged on the indoor side. The material may be a broom steel plate, a fluororesin-coated steel plate, a special steel plate having high heat resistance, a stainless steel plate, a non-ferrous metal plate, an alloy plate thereof, or the like.

The heat insulating material 40 is so-called rock wool made of silicon dioxide, calcium oxide, or the like. The heat insulating material 40 is formed to have a length of about 1000 mm and a width of about 3000 mm, similarly to the front side surface material 20 and the back side surface material 30 to be sandwiched, and the thickness is before being sandwiched between the two surface materials 20 and 30. In the state of, it is formed to be about 75 mm. As described above, when the heat insulating material 40 is filled between the two surface materials 20 and 30 of the refractory panel 10, the heat insulating material 40 is formed of both surface materials 20 and 30 so that the thickness of the refractory panel 10 is about 75 mm. It is said to be in a compressed state between them. The heat insulating material 40 is adhesively fixed to the back side surfaces of both surface materials 20 and 30 with an adhesive such as a urethane resin. The heat insulating material may be, for example, a plate-shaped foamed resin such as foamed styrene or urethane foam, or glass wool.

As shown in FIG. 5, the lower end side of the refractory panel 10 is a concave portion 12 having a concave center in the width direction. On the other hand, the upper end side of the refractory panel 10 is a convex portion 14 having a convex center in the width direction. As will be described later, a reinforcing material 50 for locking and fixing the surface materials 20 and 30 so as not to expand in the width direction is attached to the lower end side of each refractory panel 10. In this example, three reinforcing members 50 are attached to each refractory panel 10.

Next, an assembling structure and an assembling method of the refractory panel unit 1 configured by combining a plurality of the refractory panels 10 thus configured will be described. As shown in FIGS. 2 and 3, each refractory panel 10 includes a furring strip 60 vertically arranged along a joint portion of the refractory panels 10 adjacent to each other in the lateral direction, a panel connecting member 62, and the panel connecting member 62. They are fixed to each other via a screw bolt 64. The furring strip 60 is called a lip channel steel, and is made of a material such as rolled steel for general structure (JIS G 3101).

The furring strip 60 is attached from the back side of the refractory panel 10 along the longitudinal joint portion of the plurality of refractory panels 10. As shown in FIG. 2, two furring strips 60 having a "U-shaped" plan view are attached so as to face each other. These furring strips 60 are fixed to the refractory panel 10 via a panel connecting member 62 having a "hat type" in a plan view. More specifically, as shown in FIG. 3, these are fixed by the screw bolt 64 penetrated through the front surface material 20, the heat insulating material 40, the back surface material 30, the panel connecting member 62, and the furring strip 60. ing. As shown in FIG. 2, the screw bolt 64 is attached at the portion of the convex portion 14 of the upper end edge of the refractory panel 10. As shown in FIG. 2, at the joint portion in the vertical direction of the plurality of refractory panels 10, the filler 66 is filled on the opposite side to the furring strip 60, and the front side of the filler 66 is further sealed. The material 68 is fixed.

Further, as shown in FIG. 3, along the side view direction of the fireproof panel 10, the convex portion 14 on the upper end side of the lower fireproof panel 10 is contained in the concave portion 12 on the lower end side of the upper fireproof panel 10. Is fitted and fixed. In these fitting portions, the filler 66 is filled in the same manner as the above-mentioned vertical joining portion. Further, the plurality of refractory panels 10 fitted in the vertical direction are fixed by screw bolts 64 screwed to the respective refractory panels 10 and a furring strip 64 straddling each of the panels. They are connected by 60.

Next, the reinforcing material 50 for preventing the fireproof panel 10 from spreading in the width direction (thickness direction) will be described. As described above, in this example, as shown in FIG. 5, three reinforcing members 50 are attached to the lower end side of the refractory panel 10. In this example, three reinforcing members 50 are attached every about 350 mm, but they may be changed to other intervals as appropriate. As shown in FIG. 6, the reinforcing material 50 is formed in an approximately "U-shaped" shape, and is formed by bending the central piece 52 having a rectangular shape and one side of the central piece 52 in the longitudinal direction at a right angle. A long piece-shaped first locking fixing portion 54 and a short piece-shaped second locking fixing portion 56 formed by bending at a right angle from the other side in the longitudinal direction are provided. In this example, the dimensions of each part are such that the central piece 52 is about 54 mm, the first locking fixing portion 54 is about 40 mm, and the second locking fixing portion 56 is about 19 mm in the width direction. Each piece is 50 mm. The thickness of each piece is about 1.6 mm.

Next, with reference to FIG. 7, the fixing of the front side surface material 20 and the back side surface material 30 of the refractory panel 10 by the reinforcing material 50 will be described. As described above, a concave portion 12 is formed on the lower end side of the refractory panel 10. The concave portion 12 is formed in a "U" shape with the lower side open in a side view. In the concave portion 12, the front side surface material 20 and the back side surface material 30 are formed with a first folded portion 21 and a second folded portion 31, respectively. Then, the first locking fixing portion 54 of the reinforcing material 50 is inserted into the inside of the first folded portion 21 of the front side surface material 20, and the front side surface material 20 is locked and fixed in the surface side direction. The second locking fixing portion 56 is inserted into the inside of the second folded portion 31 of the back side surface material 30, and the back side surface material 30 is locked and fixed in the surface side direction. In this way, the reinforcing material 50 is locked and fixed to the front side surface material 20 and the back side surface material 30 at the lower end side of the refractory panel 10, so that the distance between the front side surface materials 20 and 30 does not widen. There is.

The first folded portion 21 of the front surface material 20 and the second folded portion 31 of the back surface material 30 will be described in more detail as follows. The lower end of the front surface material 20 is bent at a right angle toward the back side (inside in the refractory panel 10) at the lower end of the surface portion 22, and is further bent at a right angle so as to be folded back in parallel with the surface portion 22 to form a tongue piece. The first folded-back portion 21 formed in the above is formed. Further, from the tip portion on the inner side of the first folded portion 21, a tip portion 24 bent and formed in a direction orthogonal to the surface portion toward the side opposite to the surface portion 22 is formed.

On the other hand, the lower end of the back side surface material 30 is bent at a right angle toward the back side (inside in the refractory panel 10) at the lower end of the surface portion 32, and is further bent at a right angle so as to be folded back in parallel with the surface portion 32 tongue. The second folded portion 31 formed in a piece shape is formed. Further, from the inner tip portion of the second folded portion 31, a tip portion 34 bent and formed toward the side opposite to the surface portion 32 is formed. In the state where the refractory panel 10 is assembled, the tip portion 24 of the front side surface member 20 and the tip portion 34 of the back side surface material 30 are not formed to have a length of contact or overlap, and are shown in FIG. It is arranged at regular intervals. Further, the first folded portion 21 is longer than the second folded portion 31, and the tip of the first folded portion 21 is located below the tip of the second folded portion 31 in the vertical direction of the fireproof panel 10. It is extended like this.

As shown in FIGS. 7 to 10, the reinforcing member 50 is locked and fixed to such a concave portion 12 as follows. The first locking fixing portion 54 of the reinforcing material 50 is inserted inside the first folded portion 21 of the front side surface material 20 (the surface side of the front side surface material 20). On the other hand, the second locking fixing portion 56 of the reinforcing material 50 is inserted inside the second folded portion 31 of the back side surface material 30 (the surface side of the back side surface material 30). In this way, the front side surface material 20 and the back side surface material 30 are locked and fixed to each other in the front side direction by the reinforcing material 50 at the lower end side of the fireproof panel 10, and thus the front side surface material 20 and the back side surface. It is configured so that the distance from the material 30 does not increase.

On the other hand, as shown in FIG. 7, a convex portion 14 is formed on the upper end side of the refractory panel 10 as described above. The convex portion 14 has substantially the same shape as the concave portion 12 so that each portion is substantially in contact with the concave portion 12 on the lower end side of another fireproof panel 10 arranged above via the reinforcing material 50 or the like. It is formed in a shape. Therefore, the convex portion 14 is formed so as to be fitted in the concave portion 12. In the convex portion 14, step portions 25 and 35 are formed on the front side surface material 20 and the back side surface material 30, respectively.

The stepped portion 25 of the front side surface material 20 and the stepped portion 35 of the back side surface material 30 will be described in more detail as follows. The lower end of the front surface material 20 is bent at a right angle toward the back side (inside in the refractory panel 10) at the upper end of the surface portion 22, and is further bent and projected at a right angle so as to be parallel to the surface portion 22. The step portion 25 formed in this way is formed. Further, from the tip portion of the step portion 25, a tip portion 26 bent and formed in a direction orthogonal to the surface portion 22 toward the side opposite to the surface portion 22 is formed.

On the other hand, the upper end of the back side surface material 30 is bent at a right angle toward the back side (inside in the refractory panel 10) at the upper end of the surface portion 32, and further bent at a right angle so as to be parallel to the surface portion 32 tongue. A step portion 35 formed in a piece shape is formed. Further, from the tip portion of the step portion 35, a tip portion 36 bent and formed in a direction orthogonal to the surface portion 32 toward the side opposite to the surface portion 32 is formed. In the state where the refractory panel 10 is assembled, the tip portion 26 of the front side surface member 20 and the tip portion 36 of the back side surface material 30 are not formed to have a length of contact or overlap, and are shown in FIG. It is arranged at regular intervals. Further, the stepped portion 25 is longer than the stepped portion 35, and is formed so that the lower end of the stepped portion 25 is located below the lower end of the stepped portion 35 in the vertical direction of the fireproof panel 10.

In this way, when assembling the fireproof panel unit 1 by assembling the plurality of fireproof panels 10 having the concave portion 12 on the lower end side and the convex portion 14 on the upper end side, the upper fireproof panel to which the reinforcing material 50 is attached is attached. It can be fitted in the concave portion 12 of the 10 so as to be close to the outer peripheral surface of the convex portion 14 of another lower refractory panel 10 so as to be substantially in contact with the concave portion 12. As described above, the reinforcing material 50 locks the lower ends of the front surface material 20 and the lower ends of the back surface material 30 constituting the concave portion 12 so that the distance between them does not widen in the thickness direction of the refractory panel 10. It is fixed. Therefore, the front side surface material 20 and the back side surface material 30 constituting the convex portion 12 of the lower refractory panel 10 that is substantially in contact with the concave portion 12 are also provided with the reinforcing material 50 so that the intervals do not widen. It is indirectly locked and fixed. Therefore, when assembling a plurality of refractory panels 10, only the reinforcing material 50 is attached to one of the refractory panels 10, and both refractory panels 10 (two arranged one above the other in this example) at the joint portion are used. Can be reinforced at the same time. Therefore, it is possible to reduce the cost for reinforcement and improve the workability.

Next, a method of attaching the reinforcing material 50 to the refractory panel will be described. As described above, as shown in FIG. 5, the reinforcing material 50 of this example is attached to the lower end side of the refractory panel 10. The reinforcing member 50 configured as described above is attached to the refractory panel 10 as shown in FIGS. 8 to 10. As shown in FIG. 8, first, the reinforcing material 50 is inserted into the concave portion 12 from the side of the lower end side of the refractory panel 10. As described above, the first locking fixing portion 54 of the reinforcing material 50 is inserted into the inside of the first folded portion 21 of the front side surface material 20, and the second locking fixing portion 56 is inserted into the second folded portion 31 of the back side surface material 30. Insert it inside. Then, as shown in FIGS. 9 and 10, the reinforcing material 50 is arranged at an appropriate position by sliding in the concave portion 12 of the refractory panel 10. Since the reinforcing material 50 can be slid and fixed to the fireproof panel 10 in this way, the concave portion 12 at the lower end of the fireproof panel 10 and the convex portion 14 at the upper end side of the other fireproof panel 10. Since there is no particular protruding portion such as a separate mounting component (for example, a screw) when fitting, it becomes easy to fit smoothly as it is. Further, the convex portion 14 can be easily fitted to the concave portion 12 without any gap. Further, if the reinforcing material 50 is directly fixed with an organic solvent such as an adhesive, there may be a problem in fire resistance, but there is no such possibility. It should be noted that such mounting work may be performed in advance at the manufacturing plant of the refractory panel 10 or the like, or may be performed at the installation site of the refractory panel 10.

As described above, in this example, three reinforcing materials 50 are arranged for each refractory panel 10, but the number of reinforcing materials 50 is appropriately increased or decreased depending on the balance between cost and necessity of reinforcement. good. As described above, the reinforcing material 50 configured in this way is locked and fixed so that the distance between the front side surface material 20 and the back side surface material 30 does not widen.

Regarding the vertical assembly of the plurality of refractory panels 10 to which the reinforcing material 50 is attached, the lower refractory panel 10 is fixed to the furring strip 60 with a screw bolt 64 or the like, and then the refractory panel 10 is attached. The concave portion 12 of another fireproof panel 10 is fitted to the convex portion 14 of the 10 so that the next fireproof panel 10 is installed on the fixed fireproof panel 10, and thereafter sequentially upward. I will install it.

When the fireproof panel 10 is overheated, the front side surface material 20 and the back side surface material 30 may warp toward the front side at the lower end side or the upper end side of the fireproof panel 10, but the reinforcing material of this example By using 50, such a risk can be reduced. If the front surface material 20 or the back surface material 30 is warped, heat invades from the gaps between the fire resistant panels 10 more and the fire resistance performance of the fire resistant panel 10 may be deteriorated. Therefore, the risk of deterioration of fire resistance can be reduced. Between the refractory panels 10, only the heat insulating material 40 is sufficiently filled in the other parts of the refractory panels 10, whereas the heat insulating is not sufficient, so that heat invades from the gaps between the refractory panels 10. The present reinforcing material 50, which can be reduced, is particularly useful for maintaining fire resistance. Further, both cases are not the case where the front side surface material 20 and the back side surface material 30 are warped toward the front side, but also the case where the entire distance between the front side surface material 20 and the back side surface material 30 may be increased. The reinforcing material 50 locked and fixed to the surface materials 20 and 30 can prevent the entire surface material 20 and 30 from spreading. Therefore, it is possible to prevent a decrease in the heat insulating performance due to a decrease in the density of the heat insulating material 40.

The reinforcing material of the present invention is not limited to the above-mentioned reinforcing material 50, and the fire-resistant panel of the present invention is not limited to the above-mentioned fire-resistant panel 10, and can be appropriately changed within the scope of the gist of the present invention. Is. For example, the reinforcing material is not limited to the shape of the reinforcing material 50 described above. The reinforcing material of the present invention includes at least various means for locking the front side surface material and the back side surface material to prevent the distance between them from widening. For example, the outer surfaces of the front surface material and the back surface material (the surface portion 22 and the surface portion 32 in the above-mentioned example of the refractory panel 10) may be locked from the outside to the inside of the refractory panel. Further, the front side surface material and the back side surface material may be locked by screw bolts. When using screw bolts, it can be installed near the center of the surface of the panel, so it is possible to prevent the space between the front surface material and the back surface material from widening in areas other than the edges of the refractory panel. It is useful. In addition, various means for "locking the front surface material and the back surface material" are included.

Further, the reinforcing material is not limited to being attached to the lower end side as in the above-mentioned refractory panel 10, and may be attached to a side other than the lower end side. Desirably, it is more effective to attach the reinforcing material to any of the four sides of the fireproof panel in order to prevent warping of the edges of the front side surface material and the back side surface material and widening of the space between the front side surface material and the back side surface material. However, it may be appropriately selected in comparison with the cost and workability of mounting and the certainty of preventing such spread.

The present invention can be widely used for refractory panels used in various buildings and structures.
