Description

The present invention relates to an exterior material that can be used in a building and a fastener for the exterior material, and also relates to an armored structure for the exterior material using the exterior material.

A plurality of outer walls are laminated in order from the bottom for the purpose of giving the outer wall a design, and at this time, the lower part of the outer wall to be laminated is laminated so as to overlap with the upper part of the already laminated outer wall to give a step to the outer wall. The armor upholstery structure that produces shadows is known.

As a construction method for providing this armoring structure, a method of fixing an outer wall material (also referred to as an exterior material) to a base with a nail, aligning the next outer wall material, and fixing to the base with a nail is repeated. .. Also, as a method of fixing with nails, a method of fixing the upper end of each outer wall material with a nail or a method of driving a nail on a portion of the outer wall material that has been overlapped and fixing the two together on the base is common. It was

However, in such a conventional construction method, it takes time to align the outer wall and the construction period tends to be long, and there is a possibility that the aesthetics may be impaired when the alignment accuracy is low.

In addition, although the method of fixing with nails is not difficult to apply to a wooden base, it was difficult to use it for a steel base.

Therefore, a method using a fastener has been proposed to facilitate the alignment. For example, in Patent Document 1, a fastener having a portion for hooking the upper outer wall material is placed on the lower outer wall material, and a groove for inserting the portion to be hooked is provided on the outer wall material positioned on the upper side to form the groove. It is known that the positioning is performed by inserting the hooked portion.

JP 2001-20500 A

However, in the method described in Patent Document 1, stress is likely to be concentrated in the groove portion provided in the outer wall material, particularly the innermost portion thereof, and the outer wall is broken by the groove portion due to the pressure applied from the outer surface such as the force applied during construction. I had an easy problem. In addition, since it is difficult to secure a sufficient thickness for the outer wall portion to be hooked, there is a problem that the hooked portion is easily damaged and the yield is reduced. Further, the groove portion provided on the outer wall is a slit shape, and it requires skill to insert the hook portion of the fastener into the groove portion with the outer wall having a relatively large weight, and the construction time can be shortened. There was a problem that it was affected by the skill of the builder.

Therefore, an object of the present invention is to provide an armor upholstery structure that is simple and easy to construct and has excellent strength and aesthetics.

The present inventor has conducted extensive studies to solve the above-mentioned problems, and as a result, by defining a structure of an exterior material or a structure of a fastener to be used, and an exterior material and a fastener having a specific structure.

It is sectional drawing which shows one aspect of the armor tension structure of the exterior material of this invention. It is a perspective view for explaining one mode of the structure of the joint part of the exterior material which adjoins this invention.

Hereinafter, modes for carrying out the present invention will be specifically described.

<Exterior material>
The exterior material of the present invention will be described with reference to the drawings as appropriate. However, the drawings are merely reference drawings for understanding the present invention, and should not be construed as being limited to the embodiments shown in the drawings.

FIG. 1 is a diagram showing a back surface of the exterior material and a cross section taken along line X-X′. In this figure, the outer shape of the exterior material is in a rectangular shape when viewed from the front side.

The exterior material of the present invention has a portion on the surface to be the back surface of the present invention for fitting with a fastener described later. That is, the end 1 of one long side, which is assumed to be the lower end when armoring is applied, has a region 2 that becomes thinner inward from the inside of the back surface. ing. The region 2 having a small thickness may be present over the entire region in the long side direction, or may be present in part when viewed in the long side direction. It should be noted that it is desirable to provide a plurality of parts when providing some of them from the viewpoint of construction stability. Further, in the example of this figure, a region having a uniform thickness and a reduced thickness from the end is provided.

Since the region 2 having a small thickness corresponds to a fitting portion with a fastener described later, it is usual to provide a place where the area is provided at a position where fitting with the fastener is planned. On the other hand, since there is a possibility that the location where the fastener is bitten may change due to the relationship with the base material, it is preferable that the thin region 2 exists over the entire area when viewed in the long side direction of the exterior material.

Further, the thickness (indicated by H in FIG. 1) of the thinnest region 2 at the thinnest portion is the thickness (indicated by K in FIG. 1) in regions other than the thin region of the exterior material. It is preferable to have a thickness of 50% to 80%. More preferably, it has a thickness of 55% to 75%. By setting the thickness within the range, it is possible to secure sufficient strength even when an impact is applied from the surface side of the exterior material, and it is also possible to secure a sufficient thickness for the protrusions described below, which results in stable construction. In addition, the fastener can sufficiently support the exterior material against the stress from the surface portion of the exterior material even after construction. In addition, it is possible to express a feeling of shadow, which is a feature of the armor upholstery method.

Further, in the exterior material of the present invention, the protrusion 3 is formed in a portion of the thin region 2 on the side facing the long side end. From a different point of view, it can be considered that in the thin region 2, the protrusion 3 extends toward the end 1 of the long side. It is planned that this protrusion 3 will become a fitting portion with a fastener described later. The thickness (indicated by T in FIG. 1) at the tip of the protrusion 3 is preferably 10% to 30%, and more preferably 15% to 25% of the thickness of the exterior material. Further, the thickness of the root portion of the protrusion 3 (indicated by T′ in FIG. 1) is preferably 20% to 40% of the thickness of the exterior material, and more preferably 25% to 35%. .. Since the tip portion and the root portion of the protrusion 3 have appropriate thicknesses, high supportability can be obtained, and the construction can be performed easily and easily, and the durability against the stress applied to the exterior material after construction is advantageous. Will be things. It should be noted that the thickness of the tip of the protrusion 3 is to be obtained at a position where the height is lowered by 2 mm from the tip when the protrusion has a curved shape. In addition, since a space between the protrusion 3 and the thin region 2 blocks the action on the fastener when a force is applied from the outside of the exterior material, the bending elasticity is usually higher than that of the exterior material. It is possible to obtain excellent bending stress resistance without receiving a reaction from the fastener.

Further, it is desirable that the protrusion 3 has a shape in which the thickness thereof is gradually reduced from the root to the tip (that is, it is roughly trapezoidal or triangular when the X-X' cross section is viewed). With such a shape, the construction can be performed easily and easily, and the space 4 can be easily secured between the fastener and the exterior material (see FIGS. 1 and 5).

Further, the protrusion 3 and the peripheral portion of the protrusion may be covered with a reinforcing member such as metal or resin for the purpose of reinforcement.

There are no particular restrictions on the material or materials that make up the exterior material, but, for example, cement, an inorganic admixture, pulp, resin or the like can be used. Further, different materials may be used on the front surface side and the back surface side. It is a preferable mode to use a material having high toughness on the back surface side. In addition, the surface side is subjected to surface treatment such as embossing or other uneven shape, coating, or coating such as coating film or glass coat to give design property. It doesn't matter.

Further, it is assumed that the exterior material of the present invention has a long side portion on the side opposite to the long side on which the thin region 2 is provided, and this end portion serves as an upper end when armoring is applied. In addition, it is preferable that the step 5 is provided so as to rise from the surface to be the front surface to the surface to be the back side. By providing the step 5, it is possible to effectively prevent rain from entering the inside beyond the armored structure even if the rain is blown in. Further, there is a design advantage that the structure of the fastener can be made simple as shown in FIG.

Further, the exterior material of the present invention has a region 6 (6') having a smaller thickness from the end of the shorter side toward the inner side of the back surface, and the region 6 (6') having a smaller thickness is the short side of the exterior material. When viewed in the direction, it is preferably present throughout. It is preferable that the thin regions 6 (6') are configured to overlap each other when they are adjacent to each other. This will be described with reference to FIG. In addition, in order to facilitate understanding of the structure, the right side exterior material is cut out at the upper and lower ends. 6, the exterior material on the left side has a thin region 6 on the back surface side of the short side end portion, and the exterior material on the right side has a thin region 6'on the front surface side of the short side end portion. .. It is preferable that such a region having a small thickness is configured such that the total thickness of the regions is approximately equal to the thickness of the outer packaging material by overlapping. In addition, it is preferable to form the groove 13 in the thin region, and by adopting such a configuration, rainwater can be efficiently discharged. In addition, by interposing a sealant material as necessary, the gap between the adjacent exterior materials can be effectively closed, and even if rain is blown in, the rain will penetrate beyond the armored structure to the inside. Can be effectively suppressed.
