Abstract

PURPOSE:To improve engaging force, earthquake resistance and fire resistance of a panel surely fixed to a body by forming male-female connecting structure in not only a surface material but also a reverse material. CONSTITUTION:A metal-made plate material is used for a surface material 1 and a reverse material 21, and the surface material 1 forms in its both end edges in the lengthwise direction an engaging groove 10 and a fitting groove 17 with a section of squared shape opening its one end, providing a drop-in structure. While even the reverse material 21 forms male and female fitting structures 24, 28. The surface material 1 is integrally formed being prevented from coming into contact with the reverse material 21 by a core material 30, further a panel is fixed in one end surface so as to prevent a fixing tool from being exposed in the outside. In this way, thermal expansion, contraction and falling off of the panel by the deformation of a body and exfoliation of the surface material can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to architectural panels (hereinafter simply referred to as panels) useful for constructing the outer and inner walls of buildings and structures. More specifically, even if the decorative surface width and panel thickness are increased, the male and female mating structure will not peel off from the wall base, and fixing tools such as nails will not be exposed to the outside.
This relates to panels that can be hung vertically or horizontally.

[Conventional technology]

Conventionally, this type of panel used metal plate material as the surface material,
There are many panels that use a sheet-like material as the backing material and have a butt structure, a sawtooth structure, an interlocking structure, and a connecting part of the hook structure, which are integrated with a core material made of synthetic resin foam. ing.

[Problem to be solved by the invention]

However, this type of panel has the disadvantage that if nails, bolts, etc. are used to fix it to the frame, and if it is fixed from above, it cannot follow the deformation of the frame due to earthquakes, etc., and it may break. In addition, in the case of large panels with a decorative surface width of 600 to 900 mm, the conventional construction method has been to pierce the surface from the decorative surface, which exposes fixings such as nails and bolts on the decorative surface. This resulted in a significant deterioration of aesthetics and weather resistance. Furthermore, if the front and back materials are metal plates, the front and back materials will come into contact at the joints, and in the event of a fire, the heat from the front material will be transferred to the back material at the joints, which are the weakest points. This causes a problem with fire resistance, as it can cause a so-called thermal bridge and cause the joint to be destroyed. In addition, this type of panel has a male and female connection structure formed on the surface material side, and is only fixed to the frame by connection with the surface material, and the back material only functions as a reinforcing material that covers the back surface of the core material. , the backing material was not involved in the engagement of the panels at all.

[Means to solve the problem]

Taking these points into account, the present invention uses metal plate materials for the front and back materials, and forms engagement grooves with a substantially U-shaped cross section on both ends of the front material in the longitudinal direction. In addition to having a drop-in structure, a male and female mating structure is also formed on the back material, and by integrating the front material and back material with a core material so that they do not come into contact, the panel can be fixed at one end and fixed. It also prevents panels from being exposed to the outside, and prevents panels from peeling off and surface materials from peeling off due to panel thermal expansion, contraction, and deformation of the frame (earthquakes, etc.), passes fire resistance tests, and even protects decorative surfaces. This provides a panel that can be increased in width and thickness and is easy to construct.

[Example] A panel according to the present invention will be described in detail below using the drawings. FIG. 1 is a representative example of the above-mentioned panel A, which has a sandwich structure consisting of a top surface material, a back surface material (2), and a core material 30. The needles on the surface material and the back surface material are made of metal plates, such as i, Fe, Cu, stainless steel, aluminum/zinc alloy plated steel plate, colored steel plate, enamel steel plate, fluororesin coated steel plate, clad steel plate, sandwich steel plate, etc. One type is formed by press molding, extrusion molding, roll forming, etc. Panel A shown in FIG. 1 has a decorative surface part I, a male type connecting part 1, and a female type connecting part shell. More specifically, as shown in FIG. 2, on the surface material, a gutter-like part 1a is formed from a horizontally long decorative surface part I, a male type connecting part i, and a female type connecting part. It is formed from a decorative surface 2a, a side wall 3.4 in which the longitudinal edge of the decorative surface 2a is bent inward at an arbitrary angle, and a joint base 5 with the lower edge of the side wall 3 protruding outward. . The male connecting part has an upper edge 8 that bends the tip of the joint base 5 inward, an insertion edge 7 consisting of the tip of the joint base 5 and the upper edge 8, and a tip of the upper edge 8 that bends outward. A protruding lower edge 9, an engagement groove 10 formed with a substantially U-shaped cross section from the upper edge 8 and the lower edge 9, a fixing piece 11 that protrudes further outward from the lower edge 9, and a tip of the fixing piece 11. It consists of a reinforcing piece 12 hanging downward, and a groove 13 formed on the fixed piece 11.

As shown in FIG. 4, the insertion edge 7 is engaged with a fitting groove 17 for a female connecting portion, which will be described later, and the engagement groove 10 is engaged with an engagement edge 18.
This is the part that is fixed to the frame α. In addition, the groove portion 13 serves as a mark for the placement position of the fixing tool β when fixing the panel A, and forms a gap in the connecting portion between the panels A when the panels A are connected.
It helps prevent capillary action and strengthens waterproofness. The female connecting portion (2) is formed by an upper surface 15 with the lower end of the side wall 4 bent inward, a lower surface 16 with the tip of the upper surface 15 bent outward, and a cross section of the upper surface 15 and the lower surface 16 in a substantially inverted U-shape. A fitting groove 17, an extension part 19 that projects the tip of the lower surface 16 inward substantially parallel to the decorative surface 2a, and the lower surface 16 and the extension part 19.
The reinforcing piece 20 is made up of a reinforcing piece 20 that hangs downward from the tip of the extension part 19. This fitting groove 17
is engaged with the insertion edge 7, the engagement edge 18 is engaged with the engagement groove 10,
This is the part that fixes panel A to the frame α. As shown in FIG. 3, the back material needle has a cross section consisting of an upwardly projecting rising piece 22 at one end edge of a long metal plate, and a horizontal piece 23 with the tip of the rising piece 22 bent outward. A pair of approximately ■-shaped insertion portions and a reinforcing piece 25 with the tip of the horizontal piece 23 projecting upward.
, and has an approximately U-shaped cross section consisting of a rising piece 26 protruding upward at the other end and a horizontal piece 27 with the tip of the rising piece 26 bent inward, and a horizontal piece 27. A reinforcing piece 29 is formed with the tip of the reinforcing piece 29 projecting upward, and a gutter-like part 21a is formed.As shown in FIG. It is fixed on α, and the male and female connection structure on the surface material, the fixing to the panel by the fixing device β, and the fixation to the frame α are threefold, and the engagement force of panel A, earthquake resistance, fire resistance, etc. This prevents flame from penetrating into the α side of the frame due to deformation over time. In addition, the back material phantom covers the back surface of the core material 30 to make the panel A a sandwich structure, improving the mechanical strength of the panel A itself, and also using noncombustible materials, waterproof materials, heat shielding materials, sound insulation materials, backing materials, etc. It is useful as one of the functions of Core material 30
Mainly uses synthetic resin foam, which functions as a heat insulator, waterproof material, soundproof material, cushioning material, fireproof material, etc. For example, polyisocyanurate foam, phenol foam,
Synthetic resin foams such as polyurea foam and polyimide foam, and flame retardants (borates, silicates, phosphates, etc.), flame retardant aids (gypsum slag, talc, shirasu balloons, etc.) and bone in these synthetic resin foams. Materials (perlite, glass peas, etc.), fibrous materials (long and short fibers) mixed coarsely or densely, coated with phenol foam powder around pearlite, and foamed by heating and pressurizing. It is made of a single material or a combination of multiple materials, such as gypsum board, rock wool board, glass wool board, ALC, insulation board, wood chip board, glass wool, etc. In addition, the core material 3o is formed by filling the gutter-like portions 1a and 21a on the surface material and the back material (2), and at the same time preventing the reinforcing pieces 12.20 and 25.29 from coming into contact with each other. Even if the top of the material is heated due to a fire or the like, the heat will not be transferred to the backing material (■), and the fire resistance will be improved by preventing thermal bridging. Furthermore, the relationship between the opening widths W+ and W2 of the gutter-like portions 1a and 21a on the front surface material and on the back surface material (2) is W+'qWg.

Next, a construction example will be briefly explained. Assume that panel A as shown in FIG. 1 is used and construction is performed as shown in FIG. 4. In addition, for panel A, a color steel plate with a thickness of 0.5nrm was used as the surface material and the back material needles, and the core material 20
In this case, polyisocyanurate foam is discharged as a raw material, reacted and foamed, and then cured and integrated. Therefore, the fixing piece 11 of the nth panel A+ is attached to the main pillar, stud, waterproof sheet, or steel frame base α.
is fixed via a fixing device β such as a bolt. Next, insert the fitting groove 17 of the female connecting part (■) of the n+1st panel A2 into the insertion edge 7 of the panel A1, and insert the insertion part into the insertion part of the back material (■). It is thickened to form a horizontal joint as shown in Fig. 4. Furthermore, in order to form the entire wall, it is sufficient to carry out the steps described above from the base toward the girder.
