Abstract

(57) [PROBLEMS] To provide a wall panel for a curtain wall provided with an inexpensive fireproof coating material that is lightweight, has impact resistance, and can be freely curved. A ceramic fiber felt layer (3) is laminated on a rock wool felt layer (2) on the inner surface side of a wall plate (1) formed by bending a metal plate in a U-shape, and a dusting prevention cloth (4) is laminated on the surface of the ceramic fiber felt layer. The fireproof coating material A, which is sewn together with the metal wire 5 to be integrated, is adhered with the dust-prevention cloth on the front side. [Effect] Since the fireproof coating material has flexibility, complicated curved surface processing can be easily performed according to the shape of the metal plate. Further, since the dust-preventing cloth can prevent the fibers from scattering from the surface of the ceramic fiber layer, a good working environment can be maintained during the fireproof coating work.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to improvement of a wall panel used in a curtain wall construction method for a building.

[0002]

[Prior art]

 Conventionally, as a wall panel used in the curtain wall construction method for buildings, a fireproof board such as a fiber-containing calcium silicate board is adhered to the back side of a metal wall board such as aluminum or stainless steel in a single layer or multiple layers. There are known coatings, fireproof coatings by spraying rock wool on the back side of a metal wall plate, and further fireproof coatings by using a rock wool spraying layer and the above fireproof board together.

[0003]

[Problems to be solved by the device]

 The wall panel constructed as described above has no particular problem in fire resistance, but has the following drawbacks.

In the case of a wall panel in which a fireproof board provided on the back side of a metal wallboard is used as a fireproof coating: a) A heavy fireproof board causes the curtain wall itself to be heavy, resulting in a large-scale construction, and further, in a whole building. It also leads to an increase in weight. b) In the case of laminated fireproof boards, expansion / contraction, warpage, bending, etc. of the boards occur due to the temperature difference and humidity between the outdoor surface and the indoor surface, resulting in peeling between layers or between metal plates. It c) Fireproof boards are apt to be cracked, chipped, or scratched due to impact during transportation. d) The refractory board is difficult to be curved to match the shape of the metal plate.

In the case of a wall panel in which the spray material is a fireproof coating: a) The material is scattered during the spraying work, so that the work environment is polluted. b) It may peel off or fall off due to shock during transportation. c) The refractory layer made of sprayed material is as heavy as the above-mentioned refractory board, and the curtain wall itself is heavy, which leads to a large scale of construction and also leads to an increase in the weight of the entire building. d) Since a curing period of about one month is required after spraying, storage during that period is required, and it is often built without sufficient curing. In this case, construction is performed with excess water content. , Dripping and high humidity inside the wall, and mold develops inside the wall. e) The dimensional accuracy of the sprayed thickness is poor.

The present invention has been made in order to solve all of the problems mentioned above, and is a curtain wall provided with an inexpensive fireproof coating that is lightweight, has impact resistance, and can be freely curved. Its main purpose is to provide wall panels for use.

[0007]

[Means for Solving the Problems]

 A wall panel for a curtain wall according to claim 1 of the present invention is formed by bending a metal wall plate into a U-shape, and laminating a ceramic fiber felt layer on a rock wool felt layer on the inner surface side of the metal wall plate. The gist is that the fireproof coating material, which is made by stacking and integrating dust prevention cloths, is attached with the dust prevention cloths on the front side. Also, in the wall panel for curtain wall according to claim 2 of the present invention, a metal wall plate is formed into a concave and convex corrugated shape, and a rock wool felt layer and a ceramic fiber felt layer are laminated on one side thereof to form a ceramic fiber felt layer. The main feature is a structure in which a fireproof coating material, which is formed by superimposing dust-prevention cloths on the surface and integrating them, is adhered with the dust-prevention cloths on the front side.

In the wall panel for a curtain wall having the above structure, since the fireproof covering material provided on the metal wall plate has the ceramic fiber felt layer having excellent heat resistance arranged on the front side, the fireproof covering material is directly exposed to the flame in case of fire. However, the function as a fireproof coating is sufficiently maintained. Also, since it is combined with the rock wool felt layer, the refractory coating material can be obtained at a low cost as a whole.

In addition, a dust-preventing cloth is formed on the surface of the fireproof coating material, and this dust-preventing cloth prevents the scattering of fibers from the surface of the ceramic fiber felt layer inside thereof. Further, the fireproof coating material is lightweight, does not cause cracks, chips, or scratches even when it receives an impact, and can be freely curved, and the thickness dimension accuracy can be easily obtained.

[Embodiment of device]

 As an embodiment of the present invention, as shown in FIGS. 1 and 2, a rock wool felt layer 2 and a ceramic fiber felt layer 3 are laminated on the back side of a wall plate 1 formed by bending a metal plate into a U-shape. Then, the dust-preventing cloth 4 is superposed on the surface of the ceramic fiber felt layer, and the fireproof coating material A, which is sewn and integrated with the metal wire 5, is attached so that the dust-preventing cloth 4 is on the front side. Configure.

【Example】

 1 and 2 show an embodiment of the present invention. In the figure, 1 is a wall plate formed by bending a metal plate of aluminum, stainless steel, steel or the like into a U-shape. A is a fireproof coating material attached to the back side of the wall plate 1. The fire-resistant coating material A is obtained by laminating a ceramic fiber felt layer 3 on a rock wool felt layer 2, laminating a dust-prevention cloth 4 on the surface of the ceramic fiber felt layer, and stitching them with a metal wire 5 to form one body. The dustproof cloth 4 is adhered to the metal wall plate 1 by adhesion on the rock wool felt layer 2 side so that the cloth 4 is on the front side. As described above, the wall plate in which the metal plate is bent in a U-shape has an advantage that the metal plate to be used can be thinned, and the bent part acts as a reinforcing rib of the metal plate. Also, it can be used to prevent the crush of the fireproof coating material.

FIG. 3 shows another embodiment of the present invention. In this embodiment, a corrugated plate that is bent and formed in an uneven shape is used as the metal wall plate 1, and the refractory coating material A is superposed on one surface of the corrugated metal wall plate 1 and fixed by welding pins 6. According to the configuration in which the metal plate is bent into a corrugated shape as described above, a thin metal plate and a strong wall plate can be obtained. Even if the wall plate is bent into a corrugated shape, the refractory coating material can be freely curved, so that it can be easily attached along the uneven surface of the corrugated wall plate.

FIG. 4 shows a curtain wall structure in which the wall panel for the curtain wall of FIG. 1 is attached to the building frame. In the figure, 7 is a slab and 8 is a panel fixing fastener.

[Effect of device]

 According to the construction of the wall panel for the curtain wall of the present invention, the following effects can be obtained. 1) The laminated material of ceramic fiber felt and rock wool felt layer, which is the main part of the fire resistant coating material, has excellent heat resistance and fire resistance, and is lighter than the conventional fire resistant board and spray material layer fire resistant coating. Therefore, not only the wall panel for curtain wall, but also the weight of the whole building is reduced. 2) The fire-resistant coating material has a ceramic fiber felt layer having excellent heat resistance (about 1300 ° C) on the surface side that is directly exposed to a flame in the event of a fire, and the backside has a heat resistance (about 800 ° C) higher than that of ceramic fibers. ) Is low, but an inexpensive rockwool felt layer is placed and the advantages of both are taken into account, so a curtain wall wall panel that can withstand a fire temperature (about 1100 ° C) and is low cost as a whole is provided. can get. 3) Since the fireproof coating has flexibility, it not only expands and contracts the panel due to temperature changes, but also withstands body distortion such as an earthquake and shock during transportation. 4) Since curing is unnecessary, it can be transported and constructed immediately after fireproof coating. 5) Since there is a dust-prevention cloth on the surface of the fireproof coating, dust is less generated by scattering of fibers from the ceramic fiber surface during the fireproof coating work, and a good working environment is maintained. 6) The dust prevention cloth also has a reinforcing effect on the fiber felt. 7) The flexible fireproof coating can easily perform complicated curved surface processing depending on the shape of the metal wall plate. Also, the dimensional accuracy of the thickness is good. 8) Since the refractory coating material does not contain water, dust is unlikely to be generated in the wall and mold is unlikely to occur. 9) Since the refractory coating material is manufactured in a factory, the product is stable.
