Description

[Detailed description of the invention] (Field of industrial application) The invention relates to the connection structure of exterior panels of buildings, etc.
In particular, the present invention relates to a connection structure that can be suitably used for connecting horizontally attached exterior panels of buildings.

(Prior Art) Exterior walls of buildings, etc. have traditionally been constructed by connecting exterior plates made of a large number of colored steel plates in the vertical and horizontal directions.

FIGS. 7 to 9 show an example of a conventional outer wall structure, in which the strip-shaped outer panels 1' are connected in the horizontal direction in a staggered manner. The horizontal connection is as shown in FIG.
Bend the end toward the indoor side to form the ear piece 14',
14', and a U-shaped drainage recess 21' is formed in the center of the steel plate connecting member 2', and the lug parts 14', 14' of the adjacent exterior plates 1', 1' are connected to each other. A configuration is adopted in which the outer plate 1' and the connecting member 2' are fitted into the drainage recess 21' and fixed to the base material 3' with fixing members 31' such as nails or screws. As shown in FIG. 9, the vertical connection structure is such that a protrusion 11' facing obliquely upward toward the outdoor side is formed at the upper end of each exterior plate 1', and a protrusion 11' is formed at the lower end of each exterior plate 1'. By forming a receiving portion 13' large enough to insert the protruding strip 11' into the receiving portion 13', and inserting the protruding strip 11' into the receiving portion 13', the lower exterior plate 1' and the upper exterior plate 1' is adopted.

However, in the case of such a configuration, when adjacent exterior plates 1', 1' are connected with the connecting member 2',
The lower end of the connecting member 2' and the receiving part 13' of the exterior plate 1'
Since gaps A and B (see FIG. 3 for B) are formed between the receiving parts 13' and 13' and between the adjacent receiving parts 13' and 13',
Rainwater blows in through these gaps A and B, and the exterior panels 1',
1' and stays there for a relatively long time, so the rust prevention treatment must be strictly applied, not only on the back side of the exterior plate, where rust prevention treatment is relatively easy. Rust also occurs on the back side of the exterior panels, and if heat shielding material is provided on the back surface of the exterior panels 1', 1', this may peel off or corrode, disrupting the original function of the insulation material. There was an inconvenience that I was unable to fulfill my duties.

Therefore, in order to eliminate such inconvenience,
It was considered to inject a filler such as caulking material into the above gaps A and B, but in this case, since the above gap A is opened to the back, it is necessary to completely seal the gap with the filler. is very difficult, and the gap B between the adjacent receiving parts 13'
It was also impossible to seal it with a filler because it opened downward.

(Purpose of the invention) The present invention was devised in view of the above circumstances, and its purpose is to reliably seal the gap formed at the lower end of the connection part, and to securely seal the gap formed at the lower end of the connection part so that the An object of the present invention is to provide a connection structure for exterior plates that can reliably prevent the intrusion of rainwater.

(Structure of the invention) In order to achieve the above object, the exterior plate connection structure according to the present invention connects exterior plates that have a fitting recess that projects toward the indoor side in the longitudinal direction of the lower end and opens upward to connect the exterior plates laterally to each other. A connection member having a draining recess formed in the vertical direction on the indoor side of the side end and facing each other at the ends thereof is arranged such that the draining recess is located between the side ends of the exterior plate. and a fitting plate part to be fitted into the adjacent fitting recess is formed at the lower end of the connecting member, and between the fitting plate part and the fitting recess of the exterior plate and the adjacent fitting recess. The space between the parts is sealed with a sealing member.

Further, for vertical connection, as shown in FIG. 4, first, the mounting piece 17 of the lower exterior plate 1 is fixed to the base material 5 with a fixing tool 6 such as a nail. Next, the fitting plate portion 25 of the upper exterior plate 1 connected by the connecting member 2,
25 is engaged with the lower protrusion 11, the upper mounting piece 17 faces the base material 5, and the mounting piece 17 is attached to the base material 5 with nails etc. as shown in FIG. Fix with fixture 6. In this case, the mounting piece portion 17 is fixed to the base material 5 in a place where the connecting member 2 is not present. After that, the fitting recess 16 of the upper exterior plate 1 is inserted into the protrusion 11 of the lower upper exterior plate 1.
In this state, the upper mounting piece 17 is fixed to the base material 5 in a state where the upper mounting piece 17 is engaged with the base material 5. Then, by sequentially repeating such operations, the vertical connection of the exterior plates 1 is completed.

FIG. 6 shows another embodiment of the invention. Compared to the above-mentioned embodiment, this one has a folded protrusion 111 facing diagonally upward toward the outdoor side on the upper part of the exterior plate 100;
By forming a substantially inverted U-shaped engagement part 115 at the tip of the rising part 113 in the fitting recess 116, the engagement part 115 can be engaged with the protrusion 111 of the lower exterior plate 100 from above. The major difference is that they can be matched together, and the other parts are the same, so similar parts will be designated by the same reference numerals as in the previous embodiment, and a description thereof will be omitted.

Furthermore, in the above embodiment, the lug portions 14, 14 were formed at the side ends 1c, 1c of the exterior plates 1, 1.
In the present invention, it is not necessary to form such lug portions 14, 14, for example, side end portions 1c, 1c.
It is only necessary to make them face each other, and various design changes can be made without departing from the gist of the present invention.

(Effects of the invention) As described above, the invention effectively prevents rainwater from entering from the front side by arranging the drainage recess of the connecting member between the side edges of the facing exterior panels. In addition, a fitting plate part is formed at the lower end of the connecting member to fit into the fitting recess of the adjacent exterior plate, and the fitting plate part and the fitting recess and the adjacent fitting plate part are formed at the lower end of the connecting member. Since the sealing member is arranged between the mating recesses to seal the space between them, there is a gap between the lower end of the connection part and the mating recess of the exterior plate, and a gap between the adjacent mating recesses. The resulting gaps can be reliably sealed with the sealing member, and therefore rainwater can be effectively prevented from entering through these gaps. Therefore, it is possible to effectively prevent rust from the back side of the exterior plate, peeling of the heat insulating material, corrosion, etc., which conventionally occur.
