BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing panels useful for constructing exterior and interior walls of buildings and structures. More specifically, even if the width of the decorative surface and the panel thickness are increased, the male and female mating structure will not peel off from the frame, can be hung vertically or horizontally, and has complete fire protection and fire resistance. The present invention relates to a method for constructing panels that has the following features and is easy to construct.

0002

[Prior Art] Conventionally, the joints of this type of panel were as shown in Fig. 10.
Panel a with a real structure formed on the back side as shown in
A method has been devised in which the panels are connected by a male-female fitting structure, and the end of the panel a1 is fixed to the frame body α by a fixture β.

0003

[Problem to be Solved by the Invention] However, a gap γ is formed between the panels a1 and a2 by the head of the fixing tool β, and rainwater etc. blown up from the joint part b is prevented from forming the frame α by this large gap γ. There was a drawback that it could be transmitted to the side and corrode the main body α. Furthermore, since the fixture β is formed near the joint part b, rainwater etc. can directly reach the head of the fixture β,
Since the fixture β reaches the fixing hole drilled in the panel a1, there are drawbacks such as rusting of the fixture β and rainwater entering the frame α from the fixing hole. In addition, this type of panel a has a synthetic resin foam integrally formed between the metal front and back materials, and since the synthetic resin foam that serves as the core material is flammable, it is compliant with JIS-A-1301, JIS -A-130
Although it somehow passed the fireproof structure test of No. 2, there was no certainty that it could pass the fireproof structure test of JIS-A-1304.

0004

[Means for Solving the Problems] In order to eliminate such drawbacks, the present invention provides a real structure for connecting panels on the body side, fixing the panels at one end, and fixing the panels from the surface side of the surface material. However, the fixing groove of the male connecting part and the upper surface of the female connecting part cover the fixing tool to prevent the fixing tool from being exposed to the outside. A sill plate having a substantially inverted T-shaped cross section and a locking piece is interposed, and the locking piece of the sill plate locks one end of the back material of the panel, and the fixing piece of the sill plate and the panel The present invention provides a method of constructing a panel that has enhanced waterproofness, airtightness, fireproofing, fire resistance, wind pressure resistance, etc. by integrating the backing material with rivets at predetermined intervals.

[0005]

[Example] The method of constructing a panel according to the present invention will be explained in detail below with reference to the drawings. 1 and 2 are explanatory diagrams showing one embodiment of the method for constructing the above-mentioned panel, where A is a siding board, B is a panel, α is a frame, β is a fixture, and β1 is a rivet.

As shown in FIG. 3, the slat plate A is made of a metal plate material by roll forming or extrusion molding, and is made of a horizontal fixed piece 1 and a vertical piece that projects upward from approximately the center of the fixed piece 1. 2a and a locking piece 2 with the tip of the vertical piece 2a bent outward, and as shown in FIG. The inner piece 20 of the panel B is integrated with the locking piece 2, and as shown in FIG.
is the rivet β1 at a predetermined pitch (for example, 303 mm)
It is integrated by In addition, in the figure, fixing piece 1
Both pieces are integrated with the rivet β1, but if it is difficult to drive the rivet β1 from the back side during construction, only the lower fixing piece 1 is integrated with the back side material 19. This panel board A covers the back joint of panel B and strengthens the waterproofness, airtightness, fireproofing, fire resistance (prevention of flame intrusion in the event of a fire), wind pressure resistance, etc. of the back joint.

As shown in FIG. 4, panel B has a sandwich structure consisting of a front surface material 3, a back surface material 19, and a core material 24. , Fe, Cu, stainless steel plate, titanium plate, aluminum/zinc alloy plated steel plate, color steel plate, enameled steel plate, fluororesin coated steel plate, clad steel plate, sandwich steel plate, etc., formed by roll forming, press forming, extrusion molding, etc. It is something.

It is formed from side walls 5 and 6 which are bent inward at an arbitrary angle, and a joint base 7 whose lower end edge of the side wall 5 projects outward.

The male connecting portion 8 is an insert consisting of an upper edge 10 that projects further outward from the tip of the joint base 7, and a lower edge 11 that bends the tip of the upper edge 10 inward in a substantially U-shape. edge 9, a concave fixing groove 12 formed on the upper edge 10 of the insertion edge 9, and a lower edge 11.
It consists of a reinforcing piece 13 whose tip is bent inward in an L-shape.

As shown in FIG. 1, the insertion edge 9 is a part that is inserted into a fitting groove 17 of a female connecting part 14 to be described later and is fixed to the frame α, and is also a part for fixing a nail or the like in the fixing groove 12. This is a part that functions as a fixing part for fixing the panel B to the frame body α by casting the fixture β. Further, the concave fixing groove 12 is formed to be larger than the height and width of the head of the fixing tool β, so that the fixing tool β does not protrude above the surface of the joint base 7, and the panel B is engaged with the fixing groove 12. When doing so, the upper surface 15 and the joint base 7, which will be described later,
This prevents the formation of a gap at the contact portion with the upper edge 10, thereby enhancing waterproofness. Furthermore, the reinforcing piece 13 is used to reinforce the male connecting part 8 side of the surface material 3, and to insert nails or the like into the fixing groove 12 when fixing panel B to the frame α, as shown in FIG. 1, the connecting part of panel B. When the fixing device β is driven, the reinforcing piece 13 is also fixed by the fixing device β, and when the insertion edge 9 is inserted into the fitting groove 17, the insertion edge 9 is prevented from being pressed and deformed by the lower surface 16. , which helps ensure secure fixation.

The female connecting portion 14 has an upper surface 15 in which the lower edge of the side wall 6 is bent inward, a lower surface 16 in which the tip of the upper surface 15 is bent outward, and the cross section formed by the upper surface 15 and the lower surface 16 is approximately U-shaped. It consists of a fitting groove 17 formed in the bottom surface 17 and a reinforcing piece 18 with the tip of the lower surface 16 bent inward, and this fitting groove 17 is engaged with the insertion edge 9 of the male connecting part 8. Panel B on frame α
This is the part that fixes the.

The back surface material 19 is formed of an inner piece 20 having one end edge of a long plate bent inward substantially parallel to the plate, and an outer piece 21 having the other end bent outward substantially parallel to the plate. A gutter-like part was formed from these.

This back material 19 covers the back surface of a core material 24 to be described later, making panel B a sandwich structure.
In addition to improving its own mechanical strength, it serves as a noncombustible material, a waterproof membrane, a heat shielding material, a soundproofing material, a packing material, etc., and is made of the same metal material as the surface material 3. It is something. Its installation is done by integrally forming the core material 24 to be described later, and also by forming the lower edge 11 and the inner piece 2.
0, the engagement groove 22 with a concave cross section is formed between the lower surface 16 and the outer piece 21.
This forms an engaging piece 23 with a convex cross section, and as shown in FIG. , for fixing panel B to the building frame α.

As shown in FIG. 1, the inner piece 20 is held by the locking piece 2 of the siding board A to prevent it from deforming due to heat during the heating test of the fireproof and fireproof structure test. rise,
This prevents flame from entering.

[0015]Furthermore, fixing the siding board A and the panel B at a predetermined pitch, for example, 303 mm, using the rivets β1 is possible because the frame α is fixed as shown in FIG.
For example, if the pitch is 910 mm, the free siding board A stretched between the building blocks α will be integrated with the panel B at two places along the way, and the heating of the fireproof structure test and the fireproof structure test will be The inner piece 20 and the board B are not deformed by the heat during the test, and they block flames, hot air, and smoke that try to infiltrate into the back side from the joints between the panels B. Of course,
The smaller the fixed pitch between the backing material 19 and the siding board A, the more reliable the integration will be, and the higher the performance will be.

The core material 24 is mainly made of synthetic resin foam, which functions as a heat insulating material, waterproof material, soundproof material, cushioning material, fireproofing material, etc. For example, polyisocyanurate foam,
Synthetic resin foams such as phenol foam, polyurea foam, and polyimide foam, and flame retardants (borates, silicates, phosphates, etc.) and flame retardant aids (gypsum slag, talc, shirasu balloons, etc.) for these synthetic resin foams. ),aggregate(
(perlite, glass beads, etc.), materials mixed with fibrous materials (long and short fibers), materials coated with phenol foam powder around pearlite and foamed by heating and pressurizing, gypsum board, rock It is made of a single material or a combination of multiple materials, such as cotton board, glass wool board, ALC, insulation board, wood chip board, glass wool, etc. Also core material 2
4 is formed by filling the gutter-like part of the front surface material 3 and back surface material 19 in FIG. This prevents the heat from being transmitted to the backing material 19 even if it is heated, thereby improving fire resistance, heat insulation, and dew condensation resistance by preventing thermal bridges. Further, 25 is a packing material, and 26 is a sealing material, which are provided to improve waterproofness, airtightness, etc.

Here, the dimensional relationship of each part is shown in FIGS. 3 and 4.
