Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a joint structure of panels used for architecture, exterior walls, partitions, and roofs of structures.

[Conventional technology]

Conventionally, the joints of this type of panel were made by actually connecting male and female connecting parts, as described in Japanese Utility Model Publication No. 52-3047, and passing bolts through the surface of the connecting parts and inserting nuts into the base. It had a fixed structure.

[Problems to be Solved by the Invention] However, when the head of the fixture is exposed to the outside, there is a disadvantage that the waterproof property, anticorrosion property, and design of the outside are inferior.

In addition, the panel joints have the disadvantage that they cannot be used as a pattern, and they also have the disadvantage of poor thermal bridges and fire resistance. Also,
When fixing the panel to the base, it is necessary to fix the inverted T-shaped sill boards to the base at a predetermined pitch according to the layout. Moreover, the construction of the siding boards, which are installed in advance, requires high precision, making it an extremely difficult task and contributing to increased costs.

[Means to solve the problem]

In order to eliminate these drawbacks, the present invention improves workability by combining the shape of the panel side edge with a resiliently shaped sill board, and eliminates the need for layout and attaches joint covers to the joints. The present invention provides a panel joint structure in which a joint cover is fixed and a joint cover having engaging portions at both ends is integrally fitted to the joint cover fixture.

To explain further, the soil on the panel has a knot-shaped cross section and a long metal surface material 2 (hereinafter simply referred to as surface material) as shown in Figure 2, and the surface For example, a heat insulating material 8 formed on the back surface of the material 2 and serving as a core material having a substantially rectangular cross section, and a metal back material 9 (hereinafter simply referred to as back material) covering the back surface in the longitudinal direction of the heat insulating material 8. It is formed into a sandwich structure. To explain further, surface material 2,
The back material 9 is made of a metal material, such as Al, Fe, Cu,
One type of stainless steel, aluminum/zinc alloy plated steel sheet, colored steel sheet, clad steel sheet, damping steel sheet (sandwich steel sheet), fluorine-coated steel sheet, etc., is formed by press working, extrusion molding, or roll forming. That is, as shown in FIG. 3, the surface material 2 has a long decorative surface 3 and both edges of the decorative surface 3 are bent downward, perpendicular to the decorative surface 3, or inclined inwardly or outwardly. the side wall 4, the lower end of the side wall 4 is bent outward, and the protruding piece 5 is extended; ), a guide piece 7 whose end edge of the guide part 6 is bent vertically downward or in an inverted shape as shown in the figure, and a stepped part formed at the end of the protruding piece 5 for fitting the paving plate (2). 5a. The guide portion 6 serves as a guide recess 16a when installing the joint cover fixture U as shown in FIGS. The joint cover fixtures U are formed short so as not to be easily attached, and are attached to the joint part 16 in a straight line at appropriate pitches. In addition, the guide piece 7 prevents the heat insulating material 8 from leaking onto the guide portion 6 and the surface of the protruding piece 5 when filling the raw material for the heat insulating material 8, and also makes the side edges on the panel straight and has a liner. This is for making contact with the rising portion 14 of the board manure without any gap. Furthermore, the guide portion 6 and the guide piece 7 also function as reinforcement for the panel itself. Also, the length of the surface material 2 is 400
0 to 10,000 degrees, width W+ (width of decorative surface 3) is 4

In addition, the backing material 9 is as shown in FIG. 4, and as shown in FIG. 2, it mainly covers the back side of the heat insulating material 8 and has the functions of a reinforcing material, a waterproofing material, a moisture proofing material, and a fireproofing material. At the same time, it serves as an isolating material that prevents the heat insulating material 8 from coming into direct contact with the base layer α. Further, as shown in FIG. 4, the shape of the back material 9 is such that the longitudinal edge is bent vertically upward, and the reinforcing pieces 10.1
The width Ws is the width W of the surface material 2.

mm, Ha''=3 to 20 mm, and H7-2 to 10 cylinders.The back material 9 is formed so as not to contact the surface material 2, as shown in FIG. The cross-sectional structure prevents thermal bridges.

As shown in Figure 5, the section for the paving board has a deformed engineering shape.
and formed from a long body. In particular, the joint board 16
It is used for the purpose of fire prevention and waterproofing, and during construction, it can be constructed on the panel without pouring into the base α (pour can be done if necessary), and the layout avoids work and pouring into the base α. This can also improve construction efficiency. The material is one of metal thin plates, extrusions (aluminum, plastic), etc. That is, for the floorboard, it is formed from a horizontal joint back surface covering part 13, a vertical rising part 14, and a joint surface covering part 15, and the left side U-shaped holding part is used to hold the side edge 1a on the panel. It is formed to a size Hs useful for holding under elasticity. In addition, the joint part and the back covering part 13.
15, the width We, W is smaller than the width W, Wll of the joint part 16, and the dimensions of the back material 9, Ws, W? and W
The relationship is a +WtζW8, and Figure 1 (a) and (b)
As shown in Figure 2, set the dimensions of the joint cover fixture-U so that there is no problem in attaching the joint cover.

As is clear from FIGS. 1(a) and 1(b), the reason why the right side of the joint back covering portion 13 is made wider than the left side is to allow for the installation of a fixture A if necessary.

As shown in FIG. 6, the joint cover fixture H is a short metal plate made by bending, pressing, etc., and includes a horizontal fixing piece 18 and a fixing hole 19 formed on the fixing piece 18. A locking portion is formed by a rising piece 20 with both ends of the fixed piece 18 bent upward, and a locking piece 21 with the tip of the rising piece 20 bent inward, and the joint cover benefit described below is formed. It functions as a fixture to fix the panel to the joint part 16 between the upper panels. More specifically, the fixing piece 18 is a part for fixing the joint cover fixture U onto the protruding piece 5 on the panel. Further, the locking piece 21 is useful for locking an engaging piece 26 of a joint cover, which will be described later, and fixing the joint cover to the joint portions 16 on the panels. In addition, the reason why the joint cover fixtures H are made short is that by attaching a plurality of them at a predetermined pitch, even if the joint cover is separated from one of the joint cover fixtures H, the entire joint cover is maintained. This is to prevent them from leaving. Furthermore, the joint cover is made of the metal thin plate material mentioned above, and its shape is as shown in Fig. 7: a horizontal decorative surface section and a side wall decorative section with both edges of the decorative surface section bent downwardly. It consists of a surface 25 and a retaining portion r consisting of an engaging piece 26 which is bent inward so that the tip of the side wall decorative surface 25 can be engaged with the aforementioned engaging piece 21. To explain in more detail, the decorative surface part is fixed to the joint part 16 by the joint cover fixing tool H as shown in Fig. This is to cover the fixture and prevent the fixture from being exposed to the outside. In addition, the retaining piece 26 is locked to the locking piece 21 of the joint cover fixture U, and by fitting the joint cover gate to the joint cover fixture H, the joint cover gain is reliably placed on the joint portion 16. This is to fix it without coming off.

Next, a construction example will be explained.

Assume that an outer wall as shown in FIGS. 1(a) and 1(b) is constructed. Therefore, the side end portion of the panel is fixed onto the base α using a fixing device A made of a screw. Next, as shown in Fig. 5, the left side U-shaped holding part 12a of the sill board ■ is fitted into the side end 1a on the panel and attached under elastic force, and then the back side of the joint for the sill board The right side of the covering part 13 is fixed to the base α via a fixture A. Next, the side edge 1a of the panel end
is inserted into the right side U-shaped holding part 12b for the panel board, and the top of the panel is fixed to the base α via the fixing tool A. Therefore, the fixing piece 18 of the joint cover fixture H is placed on the joint part 16,
Fix it to the surface material 2 or the base α with blind rivets or bolts. Thereafter, a joint cover material is applied with elasticity to complete the joint portion 16. Of course, it is preferable to install the joint cover υ after the joint cover fixture H has been installed on the entire wall surface.

[Other Examples]

What has been described above is only one example of the joint structure of the panel according to the present invention, and in FIG. In FIG. 2, it is also possible to use a panel 1 to which a side tape is attached as shown by the - dotted chain line to have a function of preventing liquid leakage when forming the heat insulating material 8. In addition, as shown in FIG.
Figures (a) to (e) and Figures 10 (a) to (f) are other embodiments on the panel, and Figure 11 is another embodiment of the joint cover fixture H, with a guide at the end. This is a joint cover fixture (3) provided with a protrusion 18a, and FIG. 12 shows a modification of the joint cover.

〔Effect of the invention〕

As described above, according to the panel joint structure according to the present invention, ■ the panel is fixed to the base, then the sill board is attached, and then the mounting portion of the adjacent panel is brought into contact with the sill board, and then fixed. Because of its structure, there is no need to fix the siding boards to the base in positions that have been pre-assigned with highly accurate dimensions, and they are simply fixed temporarily by fitting according to the construction order, and the panel thickness, edges, etc. It is extremely easy to construct and has high efficiency regardless of other shapes. ■The head of the fixture is not exposed at the joint. ■Waterproofing, heat insulation, and fire resistance (prevention of flame infiltration) are greatly improved by the use of paving boards. ■Since the deformation when the panel is fixed is covered by the joint cover, no skill is required for construction. ■Since the joint cover fixture is short, the joint cover can be easily attached, does not come off, and is attached with elasticity. It has the following characteristics.
