Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sand inch panel (hereinafter simply referred to as a panel) used for the exterior walls, partitions, and roofs of buildings and structures.

[Conventional technology]

Conventionally, the joints formed using this type of panel were
As described in Publication No. 2-3047, the male and female type connecting portions are actually connected, and a bolt is passed through the surface of the connecting portion,
It had a structure in which it was fixed to the base via nuts.

[Problem to be solved by the invention]

However, if the head of the fixture is exposed to the outside, there are disadvantages in that the waterproof property, anticorrosion property, and design of the outside are inferior.

In addition, waterproofing treatment using caulking material or the like is required for this type of joint area, which requires time to perform and poses problems in weather resistance and durability. Furthermore, there was a problem with fire resistance.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention forms an insertion piece protruding downward with a substantially U-shaped cross section on the back material at the end of the width direction of the panel, and inserts an insertion piece into the abutment area in the width direction of the panel. To provide a panel in which a cross-sectional cross-section board can be interposed.

〔Example〕

An embodiment of the panel according to the present invention will be described in detail below with reference to the drawings. That is, FIG. 1 shows the above panel A.
It is a partially cutaway sectional view showing the.

As shown in FIG. 1, panel A has a hat-shaped cross section and a long surface material, a heat insulating material 7 formed on the back surface of the surface material, and a heat insulating material 7. It is formed into a sand inch structure from a main backing material which covers at least the backside in the longitudinal direction. To explain further, the top surface material and back surface material are mainly metal materials, such as AI SFe, Cu
, stainless steel, aluminum/zinc alloy plated steel sheet, colored steel sheet, clad steel sheet, vibration damping steel sheet (sandwich steel sheet), fluorine-coated steel sheet, etc., formed by roll forming, press working, extrusion molding, etc. That is, on the surface material, there is a long decorative surface 2, a side wall 3 bent with both edges of the decorative surface 2 downward, perpendicular to the decorative surface 2, or inwardly or outwardly; A protruding piece 4 whose lower end is bent outward and extended, and a guide part 5 for a joint cover fixture whose tip is bent upwardly or downwardly (hereinafter referred to as
It is composed of a guide portion (simply referred to as a guide portion) and a side piece 6 in which the end edge of the guide portion 5 is bent vertically downward. In addition,
The guide portion 5, as shown in FIG. 2, serves as a guide when installing a joint cover fixture as shown in FIG. 4, which has a stabilizing piece D+ in the center.

In addition, the side pieces 6 provide a gap for filling the raw material of the heat insulating material 7, and prevent the heat insulating material 7 from leaking to the guide portion 5 and the surface side of the protruding piece 4. The side edges of the panel A are made straight, and the panel This is to bring the A's into contact with each other without any gaps. Furthermore, the guide portion 5 and the side piece 6 also function as reinforcement for the panel A itself. Also, the length on the surface material is 4000
~100001st, width W+ (width of decorative surface 2) is 40
0~900m, full width W snow is around 450~1200m,
The width W from the lower edge of the side wall 3 to the side piece 6 is 20 to 100
■ Height HI from decorative surface 2 to protruding piece 4 is 10 to I
He holds the OQ cabinet rank. The heat insulating material 7 mainly functions as a heat insulating material, a waterproof material, a sound absorbing material, a buffering material, or a fire prevention material. The material is polyisocyanurate foam,
Polyurethane foam, phenol foam, polyurea foam, one type of these with flame retardant or flame retardant additive added, or a laminate of one or more of these, or one or more layers of mineral fibers or inorganic molded bodies. It consists of a laminated structure. The heat insulating material 7 is made by discharging a raw material onto the back surface of the surface material and integrating it with a mold structure, or by integrating the molded body with an adhesive.

In addition, as shown in Fig. 1, the back material mainly covers the back side of the heat insulating material 7 and has the functions of reinforcing material, waterproof material, moisture proof material, and fire prevention material, and also allows the heat insulating material 7 to directly contact the building frame α. It serves as an isolating material to prevent In addition, the shape of the back material (■) includes a notch 9 that is depressed near both edges in the width direction, a locking groove 10 that is depressed with the tip of the cutout 9 having an approximately inverted 0-shaped cross section, and a locking groove 10 that is depressed in the vicinity of both edges in the width direction. It consists of an insertion piece 11 that protrudes by bending the tip of the groove lO in a 0-shape, and a side piece 12 that protrudes further upward from the tip of the insertion piece 11. To explain in more detail, the cutout 9 is intended to prevent a step or a gap from being formed between the panels A and between the frame α and the back side main body due to the fixed piece of the board B as shown in Fig. 3. Yes, insert piece 1
1 is inserted into the 8 m grooves of the siding board B, and the joint material C planted in the 8 m grooves is compressed and brought into close contact during construction. Also, for the main back material, the total width is Wl, and the notch 9
The width from the side piece 12 to the side surface 10a of the locking groove 10 is Wl, the height from the deepest part of the locking groove 10 to the back surface on the surface material is hI, and in the paving board B, the fixed piece If the width of B+ is Wt, the width of groove B snow is We, and the height of locking piece B3 is hm, then W mushroom "iW*, W@"iWt, Wa ζW
The relationship is s/2, hI ζht. In addition, the back material ■
As shown in FIG. 1, it is preferable to form it so that it does not come into contact with the surface material, and to form it so that the surface material and the back surface material do not form a thermal bridge.

Next, a construction example will be explained.

In order to construct the outer wall as shown in Fig. 2, 600 sill plates B as shown in Fig. 3 are installed on the frame α made of C-shaped steel.
■Fix vertically with multiple screws, etc. at a pitch.Next, as shown in Figure 1, a 600mm wide panel A+, place the notch 9 of Am on the fixing piece B+, and insert the insert piece 11.
is inserted into the groove B to compress the joint material C, and the protruding piece 4 is fixed to the frame body α using a fixing device β made of screws, etc. Next, a joint cover fixing device as shown in Fig. 4 is attached. A plurality of are fixed using fixing tools β. When all the joint cover fittings have been installed, attach a long joint cover E as shown in Fig. 5 to the locking part Dx of the joint cover fitting.
The construction is completed by fitting the retaining portions EI of the panel A and covering the joint portions F between the panels A with a joint cover.
