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.

[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.

Another drawback was that the joints of the panels could not be used for pattern binding.

To explain in more detail, Panel A has a hat-shaped cross section as shown in Figure 2, and is pasted on a long metal surface material (hereinafter simply referred to as the surface material) and on the back side of the surface material. It is formed into a sandwich-inch structure from a heat insulating material 7 having a hat-shaped cross section and a metal back material 8 (hereinafter simply referred to as back material) covering at least the back surface of the heat insulating material 7 in the longitudinal direction.

To explain further, the surface material and the back surface material 8 are metal materials, such as one type of metal material such as Al, Fe, Cu, stainless steel, aluminum/zinc alloy plated steel sheet, color steel sheet, clad steel sheet, vibration damping steel sheet (sand inch steel sheet), etc. It is molded by press working, extrusion molding, and roll forming. That is, on the surface material, as shown in FIG. 3, there is a rectangular decorative surface 2,
A side wall 3 bends both edges of the decorative surface 2 downward, perpendicular to the decorative surface 2, or inwardly or outwardly, and a protruding piece 4 extends by bending the lower end of the side wall 3 outward. , consisting of a joint cover fixture guide part 5 (hereinafter simply referred to as the guide part) whose tip is bent upwardly or downwardly, and a side piece 6 whose end edge of the guide part 5 is bent vertically downward. This is what I did. As shown in Fig. 1, the guide part 5 serves as a guide when installing the joint cover fixture C having a bent part in the center, and in particular, it ensures that the joint cover D does not come off easily. When the joint cover fixtures C are formed into short lengths like this, it becomes easy to arrange them in a straight line and attach them. In addition, when filling the side piece 6 with raw materials for the heat insulating material 7,
This is to prevent the heat insulating material 7 from leaking onto the surfaces of the guide portion 5 and the protruding piece 4, and to make the side edges of the panel A straight so that they come into contact with the adjacent panels A without 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 4
000 to 10000-, width W+ (width of decorative surface 2) is 4
Approximately 00 to 900 m, total width W snow is approximately 450 to 1100 m, width W from side wall 3 @ edge to side piece 6 is 20 to loo
m, the height H from the decorative surface 2 to the protruding piece 4.

is 10-100 m. 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 materials include polyisocyanurate foam, polyurethane foam, phenol foam, polyurea foam, one of these with flame retardant additives added, or a laminate of one or more of these, or minerals. It consists of a laminated structure with one or more layers of fibers and inorganic molded bodies interposed therebetween. The heat insulating material 7 is made by discharging raw materials onto the back side of the surface material and integrating it with a mold structure, or by integrating the molded body with adhesive, and its thickness L+, tg is t I = 15 ~
20 (bnm, t, t = about 5 to 50 ma+).The back material 8 is as shown in Fig. 4, and as shown in Fig. 1, it mainly covers the back surface of the heat insulating material 7 and provides reinforcement It has the functions of a material, waterproof material, moisture proof material, and fire prevention material, and also serves as an isolating material that prevents the heat insulating material 7 from coming into direct contact with the wall base.
As shown in the figure, bend the longitudinal edge vertically upward,
It is made of a gutter shape with a reinforcing piece 9.1o formed thereon, or a flat plate shape that covers only the back side of the heat insulating material 7, and the width w4 is the same as the width w4.
Same as 2. In addition, as shown in FIG. 2, it is preferable that the back material 8 be formed so as not to come into contact with the surface material, and to prevent the back material 8 from forming a thermal bridge on the surface material. The waterproof sheet B is a long sheet-like sheet as shown in Figure 5, and is attached to the joint area without any gaps as shown in Figure 1 to strengthen the waterproofness and airtightness of the joint area E. It is something to do.

The material is water repellent, such as waterproof tape, for example, the base material is polyethylene foam, ether or ester polyurethane foam, vinyl chloride, polyethylene, Tetron nonwoven fabric, EPDM system, and the adhesive is butyl rubber. , synthetic rubber, and acrylic. In addition, waterproof sheet B may be made of a type of material such as aluminum tape, aluminum vapor-deposited tape or other metal laminated with a polyethylene sheet, RA tape made of polyester nonwoven fabric and special rubberized asphalt compound, or asphalt felt or roofing material. This also includes the following.

As shown in Fig. 6, the joint cover fixture C is a short piece formed by bending a metal plate, and includes a fixed piece 1 in the form of a horizontal plane, a stabilizing piece 12 bent in a concave shape at the center, and a fixing piece 1. It forms a locking part consisting of a rising piece 13 with both ends of the piece 11 bent upward and a locking piece 14 with the tip of the rising piece 13 bent inward, and the joint cover D to be described later is attached to the panel. It functions as a fixture for fixing to the joint between A and A. To explain in more detail, the fixed piece 11
is a part for fixing the joint cover fixture C on the protruding piece 4 to the panel, the so-called waterproof sheet E, and the stabilizing piece 12
is a part that is inserted between the guide parts 5 of the panels A and is useful for determining the mounting position of the joint cover fixture C. In addition, the locking piece 14 is for locking a retaining piece 18 of a joint cover 〇 to be described later and fixing the joint cover D to the joint E between the panels A. By forming this, even if the joint cover D is removed from one of the joint cover fixtures B, it will be locked by the other joint cover fixture C, so that the joint cover 〇 will not peel off.
This makes it easy to attach the retainer.

Further, the joint cover D is made of the above-mentioned metal thin plate material, and its shape is as shown in FIG. The retaining piece 1 is bent inwardly into a shape that can be engaged with the above-mentioned retaining piece 14 with the end of the face F and the side wall decorative surface 17 inwardly.
8 for the engaging portion. More specifically, as shown in Fig. 1, the decorative surface side is fixed to the side of the joint with a joint cover fixture C, thereby covering the fixture β used when fixing the panel A onto the building body α. However, this is to prevent the fixture β from being exposed to the outside. In addition, the retaining piece 18 is locked to the locking piece 14 of the joint cover fixture C, and the joint cover D is secured to the joint cover fixture C.
By fitting the joint cover D onto the joint E, the joint cover D is reliably fixed (fixed) on the joint E.

Next, a construction example will be explained.

In order to construct the outer wall as shown in Fig. 1, the frame α
2, fix the panel A+ as shown in FIG.
Alternatively, the side surfaces of the heat insulating material 7 are brought into contact with each other and fixed with a fixture β to form a joint portion E. Thereafter, a tape-shaped waterproof sheet B having a width narrower than the width of the joint cover 〇 is pasted to the joint edge without any gaps. Next, a plurality of joint cover fixtures C as shown in FIG. 6 are fixed onto the waterproof sheet E of this joint portion E at a pitch of 600 mm using fixtures β.

When all the installation of the joint cover fixture C is completed, fit the engaging part -■ of the joint cover D as shown in Fig. 7 into the locking part and the box of this joint cover fixture C, and then attach the panels A to each other. The construction is completed by covering the joint E with the joint cover 〇. In addition, before attaching the waterproof sheet B, banking material, caulking material, etc. are planted at the joints to further improve waterproofness, airtightness, and depending on the material, fire resistance.

[Effects of the Invention] As described above, according to the panel joint structure according to the present invention, (1) the waterproof sheet significantly improves the waterproofness and airtightness of the joint portions. ■The head of the fixture is not exposed at the joint. ■Since the fixings are covered with a waterproof sheet, the fixings do not rust, improving aesthetics and weather resistance, and allowing the panel to maintain its fixing power over a long period of time. ■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 and will not come off.
