Description

[Detailed description of the invention] This invention is suitable for use as exterior walls of buildings where the design (beauty of the exterior) is important, such as warehouses, factories, large stores, etc. along roads and railways. This invention relates to a connection structure for horizontal exterior panels, and more specifically, a connection structure in which horizontal exterior panels made of metal with bent peaks and valleys extending in the left-right direction are opposed in the left-right direction to form vertical joints. .

As a horizontal exterior plate having relatively large peaks and valleys, one made of slate is already known. The connection portions in the left and right direction of the horizontal slate exterior panels had the following structure.

That is, as shown in Figure 7 A and B, the left and right horizontal exterior panels a are arranged with their end surfaces butted against each other, and on the back side there is a plate with the same cross-sectional shape as the horizontal exterior panels a. Formed slate draining plate b
The horizontally attached exterior panels a and the draining plates b were secured with screws, and caulking material c was applied to the abutting gap between the left and right horizontally attached exterior panels a.

In this conventional structure, since the caulking material c is exposed to the outside, deterioration cracks etc. of the caulking material c appear at an early stage and rainwater leakage is likely to occur. The appearance of the joints (vertical joints) becomes poor, and defects are more likely to occur due to deterioration of the caulking material c, especially when the gap between the butt parts becomes several millimeters. Due to restrictions from the strength of the material, the dimensions of
The longest wall was relatively small, about 2 meters long, and had the disadvantage of a large number of vertical joints per wall, which hindered the design and caused frequent water leaks.

The present invention aims to eliminate these conventional drawbacks.

That is, the connection structure of the horizontally attached exterior plate according to the present invention is as follows:
The ends of the horizontal exterior panels that are connected facing each other in the left and right direction are placed between the ends of the horizontal exterior panels between the ends of the horizontal exterior panels. It is characterized in that it is attached with a desired gap to form a vertical joint, and the gap between the end of each crest of the horizontal exterior plate and the drain plate is closed with a waterproof surface door.

Hereinafter, embodiments of the present invention will be described based on the drawings.

In the figure, 1 is a cloth foundation constructed with cast-in-place concrete or concrete blocks and finishing mortar, and on its top surface is a base material, such as two lightweight type steels with a C-shaped cross section, to which the horizontal exterior panels will be attached. Vertical furrings 2 fixed back to back are erected at predetermined intervals, and horizontal furrings 3 made of similar C-type lightweight steel are installed between the vertical furrings 2. 4 is a steel beam installed along the upper horizontal edge 3, 5 is a cap, 6 is a rain gutter, 7 is a folded roof,

According to the above embodiment, the draining board 9 is not shaped to match the cross-sectional shape of the horizontally attached exterior board 10, but is made flat in the vertical direction, and the horizontally attached exterior board 10
The gap between the mountain part 10a and the drain plate 9 is the waterproof surface door 1.
5, and caulking is applied to the overlapping portion of the waterproof surface door 15 and the horizontal exterior panel 10, so the caulking material 17 is hidden by the horizontal exterior panel 10 and is not exposed to the outside.

Therefore, the occurrence of deterioration, cracking, etc. of the caulking material 17 is prevented for a long period of time, and the caulking material 17 is
Not only does the water-stopping performance of 7 be maintained over a long period of time, but even if the caulking material 17 fades or
Even if cracks or the like occur, there is no risk that the vertical joints of the horizontal exterior board 10 will become unsightly in appearance.

Moreover, the horizontal exterior panel 1 is
In order to close the gap between the end of each peak 10a of 0 and the draining plate 9, the horizontally attached exterior plates 10 facing left and right
It is possible to form a wide gap (vertical joint S) between the ends of ... independently of caulking.

Therefore, by increasing the left and right length of the horizontal exterior panels 10 to reduce the number of vertical joints, and by widening each vertical joint to provide a visual accent, it is possible to give the exterior wall a unique design. It is possible to do so.

Also, a double-sided adhesive seal tape 18 is pasted on the mounting plate 15a of the waterproof surface door 15 attached to the end of the horizontal exterior panel 10, and the waterproof surface door 15 is attached via this seal tape 18. Horizontal cladding board 1
Since the end of the drain plate 9 is attached to a predetermined position of the drain plate 9 with a tapping screw 20, the interface between the drain plate 9 and the waterproof surface door 15 is sealed watertightly.

There is no need for special screws and screw hole machining for integrating 5 and 10, and it is possible to improve workability.

In the above embodiment, the waterproof side door 15 is attached to the horizontal exterior panel 10 and then attached to the draining plate 9, but the waterproof side door 15 is attached on the draining plate 9 in advance, and then, It is also possible to configure and implement a configuration in which a horizontally pasted exterior plate 10 is attached.

In addition, although the illustrated draining board 9 is formed so that its entire width, that is, the entire width in the left and right direction, is flat in the vertical direction, at least the left and right horizontal exterior panels 10
If the draining board has a flat part in the vertical direction that overlaps with..., all of the above-mentioned functions and effects can be achieved. It is possible to employ a draining board that is flat and has an uneven pattern formed in the portion located between the left and right horizontal exterior panels 10.

Although not shown, instead of the caulking material 17, it is also possible to use a double-sided adhesive tape made of butyl rubber or the like.

As described above, according to the present invention, the end portions of the horizontal exterior panels that are connected facing each other in the left and right direction are connected to the drainage plates for vertical joints formed on the outside of the base material such as the vertical rim. Attach the horizontally pasted exterior boards with the desired gap between them to form a vertical joint between the ends.
In order to close the gap between the end of each peak of the horizontal exterior board and the draining board with a waterproof door, the vertical joint, that is, the gap between the ends of the horizontal exterior board facing each other in the left and right direction is closed. It becomes a visual accent and improves the design of the exterior wall. Furthermore, since the gaps between the ends of each peak of the horizontal exterior panels and the draining board are closed with waterproof side doors, rainwater from the gaps can be blocked. It can prevent infiltration, and by applying caulking to the overlapped part of the waterproof side door and horizontal exterior panel, the caulking material will not be exposed to the outside, preventing water leakage due to deterioration of the caulking material, fading of the caulking material, cracking, etc. This can prevent the appearance from becoming unsightly over a long period of time.
