Abstract

PURPOSE:To form structure of a door panel for fire-prevention which can be manufactured at a factory in combining a ribbed roof and a fire-prevention wall and to enable mounting from one side in a mounting work so as to save labor and to improve efficiency. CONSTITUTION:A door panel 1 for fire-prevention is so constituted that a mounting part 6 is extended to below a trapezoidal part 5 and a rock wool plate 8 in the trapezoidal shape in conformity to a door panel portion 10 of a ribbed roof 3 is mounted in front of the trapezoidal part 5. In combining them, after suspension parts 7 and 7 are pushed into a clearance 13 of a top part 11 of a fire-prevention wall 2, the door panel 1 for fire-prevention is mounted by a steel nail 15.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire-proof door plate that can be attached from one side and is used for assembling a folded roof and a fire-proof wall.

0002

[Prior Art] Fire walls are used to prevent the spread of fire in the event of a fire, but when the roof has a folded roof, it is necessary to close off the side doors.

Conventionally, as shown in FIG. 6, a partition member 22 made of sheet metal or the like is placed on the top 11 of a fireproof wall 2 made of ALC plate or the like to match the folded plate roof 3, and rock wool is inserted from both sides. 23, 23 was filled.

[Problem to be solved by the invention]

[0004] However, since the work was to be carried out on both sides of the partition member 22, scaffolding was required on both sides, which increased the construction period. In addition, there was a lot of work to be done at heights, which made the process complicated and dangerous. In addition, since the partition member 22 is manufactured on-site by bending and fixing both side edges to match the fire wall 2, the construction time is longer.

[0005]

[Means for Solving the Problems] The present invention solves the above-mentioned problems, and includes a trapezoidal shape that fits the folded roof in front of the trapezoidal part of the frame body in which the attachment part to the fire wall extends downward. A fire prevention door plate made of a rock wool board attached, characterized in that it can be attached from one side in the process of assembling the folded roof and the fire wall, and the folded roof and the fire wall. 4. A method for assembling, characterized in that, in the assembling process, a rock wool board for preventing a gap is adhered to the top of a fire wall, and then a fire prevention face door board according to any one of claims 1 to 3 is attached. In the present invention, it is also preferable that the frame body has suspension parts projecting at right angles on both sides above the mounting part extending below the trapezoidal part, and the frame body is arranged in a figure eight shape from above the square plate. It is also preferable that the suspension part is formed by making a notch in the top and bending both side edges at right angles, with the upper part being a trapezoidal part and the lower part being a mounting part.

[0006]

[Embodiment] Fig. 1 shows a fire prevention door panel 1 according to an embodiment of the present invention.
FIG. 2 is a front view of the main parts showing a state in which the assembly process is performed using the same, and FIG. 2 is a side sectional view thereof. Further, 2 is a fireproof wall made of ALC plate or the like, and 3 is a folded plate roof formed by being bent into a rack shape.

Reference numeral 10 denotes a trapezoidal door portion between the fire wall 2 and the folded roof 3, and when it is necessary to block it for fire prevention purposes, the fire prevention door plate 1 of the present invention is used.

The fire prevention side door plate 1 of this embodiment has a side door portion 1
A trapezoidal part 5 that can be inserted into the firewall 2 is provided above, and a rectangular wide mounting part 6 that can be attached to the firewall 2 extends below the trapezoidal part 5, and can be suspended on the top part 11 of the firewall 2 at both side edges. It is provided with a thin plate-like frame body 4 in which suspension parts 7, 7 are formed to protrude at right angles to the front.

[0010] In front of the trapezoidal part 5 of the frame 4, there is a side door part 1.
A rock wool board 8 having a trapezoidal shape conforming to the firewall 2 and having approximately the same thickness as the firewall 2 is attached to a plurality of headed mounting pipes 9 using an adhesive.

Furthermore, since the fire prevention door panels 1 are attached to each of the door sections 10 of the folded roof 3 in a line, it is desirable that the width of the mounting portion 6 is slightly shorter than the pitch dimension of the door sections 10. It is also fixed to the firewall 2 with a plurality of iron nails 15.

Since the fire prevention door plate 1 of this embodiment has the above-described structure, it can be attached from the direction A on one side of the fire prevention wall 2. Therefore, the scaffolding (not shown) only needs to be erected on one side, which greatly saves labor.

[0013] Furthermore, since each side door portion 10 has the same shape,
It is possible to mass-produce the fire prevention door plate 1 as a standard product at a factory.
Installation is easier and productivity is higher than conventional on-site alignment work.

The top 11 of the firewall 2 and the bottom 1 of the folded roof 3
Although there is a slight gap 13 between 2 and 2,
When the gap 13 is small, the suspension parts 7, 7 are pushed into the gap 13 and suspended and fixed as shown in FIGS. 1 and 2.

FIG. 3 is a side sectional view showing a state in which the parts are assembled when the gap 13 is large. Top part 1 of fire wall 2
A rock wool plate 14 for preventing a gap is adhered to 1 to make the gap 13 slightly smaller, and then the suspension parts 7, 7 are pushed in and fixed in the same manner as in FIG.

FIG. 4 shows an embodiment of a mass-produced frame 20 of the fire prevention door panel 1 of the present invention.
FIG. 2 is an explanatory diagram showing the process order. 4-1 Cut a figure-eight shape from above into the rectangular plate 17 whose vertical and horizontal dimensions are the sum of the trapezoidal part 5 and the mounting part 6, and the horizontal and horizontal lengths of the mounting part 6. 4-2 Both side edges 18, 18 are bent at right angles to form suspension parts 7, 7. In this way, a trapezoidal portion is formed in the upper center and a mounting portion is formed in the lower portion. 4-3 Cut the bent side edges 18, 18 into the fixed dimensions of the suspension parts 7, 7 to complete the mass-produced frame 20. 19 indicates cutting waste.

FIG. 5 is a front view of an embodiment of a fire prevention door plate 1 comprising a simple frame 21. As shown in FIG. The frame body 21 has no suspension parts on both side edges, and is formed from an upper trapezoidal part 7 and a downwardly extending mounting part 6. In this case, a rock wool plate 14 for preventing a gap is glued to the gap 13,
The fire prevention door plate 1 may be fixed with iron nails 15. 16 is an iron nail hole. Note that a rock wool plate 8 is attached to the back side of the trapezoidal part 7.

[0018]

[Effects of the Invention] As explained above, when assembling a folded roof and a fire wall using the fire prevention panel of the present invention, it is only necessary to erect scaffolding on one side of the fire wall, which saves labor. Contribute to In addition, the use of standard fire-proof door panels eliminates the complicated labor of on-site installation, contributing to labor savings and shortening the construction period. In addition, the conventional on-site fitting work for door panels is transferred to factory manufacturing work, making labor more efficient and reducing the risk of on-site work at heights, thereby contributing to safety. Furthermore, it can be expected that the appearance after treatment will be significantly improved.
