The backing material 10 is as shown in FIG. 5, and mainly covers the inner surface of the heat insulating material 9 as shown in FIG. 3, and has functions of a reinforcing material, a waterproofing material, a moistureproofing material, and a fireproofing material. At the same time, it serves as an insulating material for preventing the heat insulating material 9 from directly contacting the skeleton α. As shown in FIG. 5, the shape of the backing material 10 is such that both ends in the longitudinal direction are bent outward at right angles to form gutters having reinforcing pieces 11 and 12 or only the inner surface of the heat insulating material 9. made like a flat plate covering the width W ₄ is the same as the W _2. The back material 10 is formed so as not to contact the front material 3 as shown in FIG.
It is preferable to form the front surface material 3 and the back surface material 10 so as not to form a thermal bridge. The caulking material D is sticky and is continuously planted in a range where the rising portion 2 of the floor plate B between the outer side surfaces of the adjacent panels C is not interposed. , Silicone-based, polyurethane-based, acrylic-based, SBR-based, etc., and acrylic high water-absorbent resin that expands when absorbing water and shrinks when dried, releases crystallization water under high heat, foams and hardens borax, meta It is a kind of compound containing sodium borate or the like, and is for improving waterproofness, airtightness, heat insulation, or fire resistance. As shown in FIG. 6, the joint cover fixture E is a short piece formed by bending a metal plate material, and includes a horizontal flat fixing piece 13, a stable piece 14 projecting inward at the center thereof, and a fixing piece 13. A locking portion 17 comprising a rising piece 15 in which both ends of the piece 13 are bent outward and a locking piece 16 in which the tip of the rising piece 15 is bent outward and the tip is turned inward. , And functions as a fixture for fixing the joint cover F described later to the joint portion G between the panels C. More specifically, the fixing piece 13 is a portion for fixing the joint cover attaching tool E on the projecting piece 6 of the panel C, and the stabilizer piece 14 is inserted between the guide portions 7 of the panels C, and This part is useful for positioning the mounting position of E. The locking piece 16 is for locking an engaging piece 20 of a joint cover F, which will be described later, to fix the joint cover F to a joint G of the panels C. When the joint cover F is disengaged from one of the joint cover attachments E, the joint cover F is locked by another joint cover attachment E, so that the joint cover F does not come off and the engagement mounting is easy. It becomes something. Further, the joint cover F is made of the above-mentioned metal sheet material, and the shape thereof is, as shown in FIG.
A side wall decorative surface 19 in which both side ends of the decorative surface portion 18 are bent inwardly at an obtuse angle with respect to the decorative surface portion 18, and a shape in which the tip of the side wall decorative surface 19 can be locked to the above-described locking piece 16 inward. And an engaging portion 21 formed by a bent locking piece 20. More specifically, as shown in FIG. 1, the joint surface F is fixed to the joint G by the joint cover fixture E, thereby fixing the panel C on the frame α. This is for covering the fixture β so that the fixture β is not exposed to the outside. In addition, the engagement piece 20 is locked by the locking piece 16 of the joint cover fixture E, and the joint cover F is fitted to the joint cover fixture E, so that the joint cover F is securely placed on the joint G. It is for fixing without detachment.

 Next, a construction example will be described.

Now, in order to form an outer wall as shown in FIG. 1, a fire-resistant inorganic sheet A made of a foamed gypsum sheet (KG sheet) is fixed to the outer surface of the body α by screws. Thereafter, a plurality of the floor boards B as shown in FIG. 2 are vertically fixed at a pitch of 600 mm, and are fixed to the frame α from the outer surface of the fire-resistant inorganic sheet with screws or the like. Next, panels C ₁ and C _{2 each} having a width of 600 mm as shown in FIG. 3 are fitted between the rising portions 2 of the floor plate B so that the outer side surfaces thereof abut against the rising pieces 2 of the floor plate B. While being mounted, the joints are formed by fixing the inner surfaces near the both side ends of the back material 10 via the fixing tool β such that the inner surfaces contact the outer surfaces of the fixing pieces 1 of the flooring board B. Standing portion 2 of the floor plate B between the outer side surfaces of the panels C in the portion G
The silicone-based caulking material D is continuously planted in a range where no is interposed. When the planting of the caulking material D is completed, the joint cover attachment E as shown in FIG.
Are inserted between the guide portions 7 of the adjacent panels C, and a plurality of them are fixed by the fixing tool β. When the joint cover attachment E is completely attached, the engaging portion 21 of the long joint cover F as shown in FIG. The joints G of C are covered with the joint cover F to complete the construction.

[Other Examples]

The above is only one embodiment of the joint structure of the panel according to the present invention, and can be formed as shown in FIGS. 8 (a) to 8 (d). That is, FIG. 1A shows a joint structure in which concave portions 22 are formed on both side edges of the back material 10 of the panel C and have a shape corresponding to the fixing piece 1 of the floor plate B, and waterproofness and airtightness are further enhanced. b) The figure shows a joint structure in which caulking material D is also planted at the boundary between the fixing piece 1 of the floor plate B and the rising portion 2.
(C) and (d) show that the fireproof inorganic sheet A is also formed on the projecting piece 6 or on the outer surface of the fixed piece 1, and the joint G has waterproof, airtight, heat insulating, fireproof, etc. The joint structure has been improved. In FIGS. 8 (a) to 8 (d), the fixing tool β is omitted.

〔The invention's effect〕

According to the joint structure of the panel according to the present invention as described above, since the fire-resistant inorganic sheet is present inside the joint,
The joint structure has greatly improved fire resistance. The caulking material greatly improves the waterproofness and airtightness at the joint. The head of the fixture is not exposed at the joint. Waterproofness, heat insulation, and fire resistance (prevention of flame penetration) are greatly improved by the presence of the siding. Since the deformation at the time of fixing the panel is covered by the joint cover, no skill is required for construction.
Since the joint cover attachment is short, the joint cover is easily attached and does not come off. Panels can be allocated by fixing the slab,
Finish is good. There are features and effects such as.
