Description

[Detailed description of the invention] [Industrial application field] This invention is intended for exterior materials that form the outer walls of buildings, so-called siding, which are horizontally installed in such a way that the exterior materials are joined together by overlapping them vertically, so that the wall surface becomes flush after construction.

[Prior art] Figure 4 shows a conventional example of this type of exterior material, the basic idea of which is described in Japanese Patent Application Laid-Open No. 61-60960.
It is publicly known in the publication No. In this case, an exterior material 1 is composed of an exterior panel 2 made of a steel plate and a heat-insulating/sound-insulating lining 4 lined with a main panel 3 of the exterior panel 2. Exterior materials 1,
Connecting protrusion 7 and engaging portion 9 for overlapping 1 to 2
are respectively provided, and a mounting piece 6 for nailing is vertically bent and protrudes from the upper part of the connecting projection 7.

Specifically, the connecting wall 5 that is inclined upward from the upper end of the main surface plate 3 is bent inward and extended, and the connecting wall 5 is
A connecting protrusion 7 is formed extending upward at a position near the inner end of the main face plate 3, and a bottom wall 8 is bent inward from the lower end of the main face plate 3 to extend upward, and a groove-shaped groove is formed on the inner end side of the bottom wall 8. An engaging portion 9 is formed. When in use, the mounting piece 6 of the lower exterior material 1 is fixed to the flange 14 with nails N, and the engaging portion 9 of the upper exterior material 1 is externally engaged with the connecting protrusion 7 from above. , by fixing the mounting pieces 6 of the upper exterior material 1 with nails N, the exterior material 1
It adopted the form of successively overlapping each other.

[Problem that the invention attempts to solve]

However, the distance from the surface of the exterior material 1 to the rim needs to be constant due to the connection of sashes such as windows, but in the conventional exterior material 1, the connecting protrusion 7 and the engaging portion 9 The structure is such that they fit and engage on the inner end side of the connecting wall 5. Therefore, the joint spacing b formed between the upper and lower exterior materials 1 and 1, and especially the joint depth d, have to be small, making it easy for rainwater to enter during storms, making it difficult to obtain good waterproof properties. The problem was that there was no.

Regarding the joint spacing b, a large gain can be made by setting the connecting wall 5 at a steep slope as shown by the imaginary line in FIG. However, in this case, it is necessary to reduce the vertical width of the lining body 4 or to form its upper end into a shape that follows the connecting wall 5, which may reduce the heat insulation/sound insulation effect and the deformation strength against external forces at the relevant part, or This leads to an increase in the manufacturing cost of the exterior material 1. In this type of exterior material 1, which aims to make the outer surface of the main face plate 3 flush in the finished state after construction, it is desirable for the joint spacing b and the joint depth d to be large for aesthetic reasons, for example, for the shading pattern. However, as mentioned above, the conventional exterior material 1 could not fully satisfy these requirements.

[Purpose of invention]

This invention was proposed to solve the above-mentioned conventional problems, and by improving the connection structure for joining the upper and lower exterior materials flush with each other, it is possible to The main focus is to increase the joint spacing and especially the joint depth.

[Means for solving problems]

That is, in the exterior material 1 of the present invention, instead of the conventional example in which the connecting protrusion 7 is provided on the side of the connecting wall 5, the connecting protrusion 7 is provided at an intermediate position between the upper and lower sides of the mounting piece 6, and the engaging portion 9 with which the connecting protrusion 7 engages also corresponds. It is characterized by being located at

Specifically, as shown in FIG. 1, the connecting wall 5 is bent inward and extended from the upper end of the main face plate 3 lined with the lining body 4, and the mounting piece 6 is vertically extended from the extending end of the connecting wall 5. The connecting protrusion 7 is formed outwardly at an intermediate position between the upper and lower sides of the mounting piece 6, and the bottom wall 8 is bent inward from the lower end of the main face plate 3 to extend. An engaging portion 9 is formed in a continuous manner so that the connecting protrusion 7 can fit into and engage with the connecting protrusion 7 while rising upward from the continuous extending end.

Here, the connecting wall 5 is formed to be sloped upward as it goes inward, and the lining body 4 and the mounting piece 6 lined on the inner surface side of the main face plate 3 are formed to be substantially flush with each other. is preferred.

[Effect]

By forming the connecting protrusions 7 continuously at the upper and lower middle positions of the mounting pieces 6, it is possible to obtain a joint depth D that is approximately equal to the distance from the outermost surface of the main face plate 3 to the innermost mounting piece 6, and the joint depth The distance B can also be made larger as the connecting protrusion 7 is positioned upward.

[Effect of idea]

Horizontal type exterior material 1 of the present invention as described above
According to the above, a connecting protrusion 7 is provided at an intermediate position between the upper and lower sides of the mounting piece 6.
On the other hand, since the engaging portion 9 with which the connecting protrusion 7 can be engaged is formed extending from the connecting end of the bottom wall 8, the length corresponding to the amount of horizontal protrusion of the connecting wall 5 is extended. can be set as the joint depth D, and it becomes possible to set both the joint depth D and the joint interval B larger than in the conventional exterior material 1. Therefore, even under usage conditions where rainwater easily enters, such as during rainstorms,
It can prevent rainwater from entering and improve waterproofness. At the same time, even in the finished state after construction, shading appears prominently and an aesthetically pleasing appearance with a three-dimensional effect can be obtained.

Further, since the connecting protrusion 7 is formed at the intermediate position of the mounting piece 6 and the mounting piece 6 is attached to the rim 14,
The upper and lower engagement strength can be ensured, and the external force can be absorbed by the bottom wall 8.
Since it is supported with

According to a preferred embodiment of the present invention, in which the mounting piece 6 and the lining body 4 are brought into almost flush contact with the mounting surface of the furring 14 to which the exterior material 1 is attached, the lining body 4 Since it is supported by the mounting surface, it will not bend inward or move loosely due to external vibrations or impacts, and it can stably exhibit heat and sound insulation effects and improve its reliability. In addition, in the conventional exterior material 1 shown in FIG. 4, since the inner surfaces of the lining bodies 4 are stacked with their inner surfaces facing each other during transportation, it is necessary to interpose spacers between the lining bodies 4 to prevent bending. However, such a pacer is also unnecessary.

[First Embodiment] Figures 1 and 2 show a first embodiment of the present invention.

In FIG. 2, the exterior material 1 consists of an exterior panel 2 formed by bending and forming a steel plate into an irregular cross section, and a heat-insulating and sound-insulating lining body 4 that is adhered and fixed to the inner surface of the main face plate 3 of the exterior panel 2. The overall shape is a horizontally long plate.

In FIG. 1, the outer panel 2 has an upwardly sloping connecting wall 5 that is bent inward from the upper end of the main surface plate 3 and extends vertically upward from the extending end (inner end) of the connecting wall 5. It has a mounting piece 6 that is extended. A connecting protrusion 7 is formed in a downwardly intermediate position of the mounting piece 6 by bending it in an inclined manner.

On the other hand, at the lower part of the outer panel 2, a bottom wall 8 is bent inward from the lower end of the main face plate 3 at a right angle and extended, and from the extended end (inner end) of the bottom wall 8, a vertical short vertical wall 11 is inserted. A groove-shaped engaging portion 9 into which the connecting protrusion 7 fits and engages is bent forward in an upwardly sloping manner so as to extend upwardly. Note that the vertical wall 11 can have a desired length, and may be omitted.

The engaging portion 9 is bent into an elongated hook shape, and a semicircular drainage portion 10 is recessed in the middle of the inclined groove wall 9a on the front side. This draining portion 10 functions to prevent water from entering due to capillary action. The vertical wall 11 contributes to improving the deformation strength of the lower panel side during connection. The vertical wall 11 is provided on the upper part of the outer surface of the vertical vertical piece portion 6a below the connecting protrusion 7 of the mounting piece 6.
can be accepted without wobbling.

The lining body 4 is formed by molding rock wool into a boat shape and cutting it to a predetermined size, and is attached to the inner surface of the main face plate 3 via an adhesive 13. The thickness of the lining body 4 is the bottom wall 8

In this way, the upper exterior material 1 is attached to the lower exterior material 1.
By overlapping and connecting and fixing the main face plates 3 one after another, an outer wall is constructed in which the outer surface of the main face plate 3 is flush with the surface after construction. In FIG. 1, B indicates the joint spacing and D indicates the joint depth. This joint depth D is maintained from the outer surface of the main face plate 3 to the vertical vertical piece 6a of the mounting piece 6. In a state where the exterior material 1 is attached to the furring rim 14, the attachment piece 6 and the lining body 4 contact the mounting surface of the furring rim 14 substantially flush.

[Second Embodiment] FIG. 3 shows a second embodiment of the present invention. In this case, the connecting protrusion 7 faces outward and extends diagonally downward,
The engaging portion 9 is immediately bent upward from the inner end of the bottom wall 8 into a substantially upright shape. In contrast to the first embodiment, which adopts a form of fitting and engagement, in the second embodiment, the engaging portion 9 of the upper exterior material 1 is hooked from below to the connecting protrusion 7 of the lower exterior material 1. It is intended to be engaged. In FIG. 3, members equivalent to those in the first embodiment are denoted by the same reference numerals and explanations thereof are omitted.

[Another embodiment example]

In each of the above embodiments, it is assumed that the lining body 4 is made of a board-like material such as rock wool or gypsum, but it is not necessarily necessary to do so. It may be closed with a sheet material made of aluminum, and the space between this sheet material and the outer surface panel 2 is filled with urethane foam.

Moreover, these shapes can be changed arbitrarily, such as making the connecting protrusion 7 have a regular or inverted L-shape when viewed from the side, and making the engaging portion 9 correspond to the shape.
