Description

The present invention relates to a prefabricated building constructed using various panels such as a wall panel, a floor panel, a ceiling panel, and a roof panel, and all or part of the peripheral wall (wall, floor, ceiling, roof, etc.) of the building. Related to the wall structure forming,
The wall structure is composed of an outer wall plate, a fireproof board, and a heat insulating panel, and the outer wall plate is a common square wave iron plate (folded plate (seppan)), corrugated iron plate (namako plate), or , Iron plate such as color iron plate, decorative iron plate, corrugated iron plate, or iron plate, fireproof board is a general building board made of fireproof material such as gypsum, calcium silicate, diatomaceous earth, or rock wool, The heat insulation panel is made of metal, hard plastic, or wood frame material. A rectangular iron plate is stretched on both front and back sides of a rectangular frame, and the fixing iron plate is narrow and long in parallel with the inner surface of the surface iron plate in advance. Various types of walls such as wall panels, floor panels, ceiling panels, or roof panels for prefabricated buildings, in which foam plastic is injected into the space in the frame formed by the rectangular frame and the front and back iron plates Pa A Le,
The outer wall plate, the fireproof board, and the heat insulation panel are arranged in a laminated manner, and the screws passing through the outer wall plate, the fireproof board, and the surface iron plate of the heat insulation panel from the outside of the outer wall plate are used as fixing iron plates on the inner surface of the surface iron plate. The three walls of the outer wall plate, fireproof board, and heat insulation panel are screwed together and screwed together, and the wall is provided in a triple layer of a wind-resistant layer by the outer wall plate, a fireproof layer by the fireproof board, and a heat insulation layer by the heat insulation panel Thus, a wall structure of a prefabricated building having three elements of storm water, fire resistance and heat insulation is provided.

Various heat insulation panels for prefabricated buildings have rectangular iron plates stretched on both front and back sides of a rectangular frame made of metal, hard plastic, or wooden frame material, parallel to the inner surface of the surface iron plate in advance Wall panels, floor panels, and ceiling panels for prefabricated buildings, which are made by adhering narrow steel plates for spacing and injecting foamed plastic into the space in the frame formed by the rectangular frame and front and back iron plates, Or it is various panels such as roof panels, and in particular, it has excellent heat insulation to block the temperature difference between inside and outside of the building, as well as durability, external pressure shock resistance, water tightness, sound insulation, etc. Widely used in prefabricated buildings such as refrigerated / refrigerated warehouses, clean rooms, various warehouses and workshops.

However, the conventional heat insulation panel has a drawback that it is remarkably lacking in fire resistance. When high heat is applied by a fire or the like, heat conduction from the surface iron plate causes the aluminum frame to be deformed and melted at a relatively low temperature. The frame burns, the foamed plastic filler melts and expands, leaks or burns to the outside, and the front and back iron plates are bent by heat and peeled off and peeled off. For example, there is a fear that it cannot be used as a fireproof building material for fireproof buildings (noncompliant with legal standards).

Therefore, in the past, when heat insulation is required, when building a building with fire resistance that meets legal standards using heat insulation panels, for example, as shown in FIG. The outer peripheral wall of the object is formed of a fireproof board 102 having excellent fire resistance, and the outer surface of the fireproof board is made of an outer wall plate 101 such as a square wave iron plate having excellent wind resistance in order to compensate for the wind resistance lacking in the fireproof board 102. The inner peripheral wall is covered with a setting space 105 for blocking heat conduction from the outer wall plate 101 and the fireproof board 102 due to a fire, inside the fireproof and windproof wall formed by the fireproof board 102 and the outer wall plate 101. A prefabricated building having a wall structure 100C, which is formed of the heat insulating panel 103 and has both fireproof / breathable water resistance satisfying legal standards and excellent heat insulating properties, is provided.
In addition, 104a is a surface iron plate of the heat insulation panel 103, 104b is a back surface iron plate, 106 is a foamed plastic, 107 is a screw, a nail, etc., 109 is a trunk edge.

However, the conventional prefabricated building having both fire resistance, wind resistance and heat insulation has to have a double wall around the building and a space between the surrounding walls. Double labor and cost are required, and since the setting space is separated, the peripheral wall becomes extremely thick, and thus there is a problem that the ratio of the internal area to the building area becomes small.

In addition, the applicant previously formed Japanese Patent Application No. 2002-257035 (Japanese Patent Application Laid-Open No. 2004-092265) with a frame material formed by bending a thick and narrow steel plate at a plurality of right angles in the cross section to form a rectangle of the same shape and the same shape. A thin face steel plate is attached to each side of the inner frame and the outer frame, and the peripheral edge thereof is bent and fixed at two right angles along the right-angled portion of the peripheral edge of each frame. A narrow intermediate plate interposed in the middle and the left and right inner and outer frames are connected with bolts and nuts, and the connecting positions of the inner and outer frames are staggered to prevent the left and right sides of the inner and outer frames from expanding outward. A filler such as rock wool is filled between the inner and outer frames on which the face steel plate is stretched, and when the adjacent panel is connected, the right-angle protruding portion of the left frame of one panel is perpendicular to the right frame of the other panel. Fit into the recess Therefore, a patent application was filed for `` fireproof panel for prefabricated building structures, etc. '' which is provided so that the right side of the inner and outer frames do not spread outward, but the fireproof panel has long-term fireproof performance However, there is an unsolved part in that the surface iron plate of the panel is bent, and further improvement is required.
JP 2004-092265 A

Accordingly, the present invention provides a wall that forms all or part of the peripheral wall (wall, floor, ceiling, roof, etc.) of a building when the conventional problem is that fire resistance is required in a prefabricated building. Paying attention to the fact that the heat insulation panel with extremely excellent heat insulation in the structure could not be used effectively,

It is very simple and extremely low-cost by simply passing through the surface iron plate of the plate, fireproof board, and heat insulation panel, screwing it onto the fixing iron plate on the inner surface of the surface iron plate, and screwing together the three members. It is possible to provide a wall structure with three layers of feng shui, fireproof board, fireproof board and heat insulation panel, and to provide a wall structure that combines the three major elements of feng shui, fireproof and heat insulation. There is a breakthrough effect that can be done.

The heat insulation panel is the same as a conventional heat insulation panel except that a fixing iron plate is embedded in advance on the inner surface of the front iron plate of the heat insulation panel. The outer wall plate uses a commercially available square wave iron plate, etc. Since a commercially available gypsum boat is used, it is possible to provide a prefabricated building that has excellent performance of storm water, fire resistance and heat insulation without requiring extra labor, time and cost. effective.

Moreover, there is an advantage which is almost the same as that of a prefabricated building made of a normal heat insulation panel in terms of the wall thickness in the building area.
