Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an exterior wall material that is attached to the wall of a building.

[Conventional technology]

Conventionally, as exterior wall materials, wood boards, galvanized iron boards, fiberboards, asbestos slates, wood wool cement boards, plastic boards, bricks, tiles, artificial stone boards, etc. have been used.

Among these, there are two ways to attach wooden boards: flat plank and mirror plank.In the case of flat planks, it is common to use hidden nails nailed into the base wood for boat fishing, but there are also methods for attaching wooden boards with adhesive. Sometimes. Also.

In the case of mirror panels, mirror panels are attached between the baseboard and the umbrella board in a frame-like manner.

For galvanized iron boards, fiberboards, asbestos slates, wood-wool cement boards, and plastic boards, the above-mentioned methods for cladding or mirror cladding shall apply.

Furthermore, bricks, tiles, artificial stone slabs, etc. can be pasted using mortar as a binding agent.

[Problem to be solved by the invention]

In any case, since conventional exterior wall materials have a flat outer surface, they receive the wind pressure directly during strong winds, and as a result, especially in the case of high-rise buildings, the building tends to sway due to the wind pressure. If the wall is hit diagonally, negative pressure will be generated on the wall surface, which may cause the outer wall material to peel off and be blown away by strong winds.

In addition, rainwater tends to stagnate on the outer surface of the exterior wall materials, and especially in buildings with circular domes, a large amount of stagnation occurs due to the wind pressure blowing up, so there is a risk that the building structure will not be able to withstand the weight of the rainwater. There was a problem in that the design was forced to use excessive amounts of materials based on calculations.

In view of the above-mentioned circumstances, this invention was developed in order to release wind pressure, so that buildings can easily withstand strong winds even when exposed to strong winds straight on, and no pressure-proofing occurs on the exterior surface even when wind pressure is applied diagonally. The purpose of the present invention is to provide an exterior wall material that does not have the risk of peeling off from a building, has good rain drainage, and allows architectural design without using excessive materials.

[Means to solve the problem]

In order to achieve the above object, this invention makes the following two proposals.

First, in the exterior wall material of the first invention, a large number of recesses are provided in a board that is attached to a building, a sphere is housed in the recess in a rotatable manner and cannot escape, and a part of the sphere is exposed to the outside from the recess. It is something.

In addition, in the exterior wall material of the second invention, a plurality of shafts are installed in parallel on a frame fixed to a building, and each shaft is rotatably supported with a large number of spheres connected in a daisy chain, so that the outer surface has an arrangement of spheres. This is what has become.

[For production]

Since the exterior wall material of the first invention is configured as described above, when it is attached to the exterior surface of a building, a phenomenon occurs in which wind runs along the exterior surface, whether wind pressure is applied from the front or from an angle. , the sphere rotates as the wind runs along the wall,
Wind pressure is absorbed by the rotation of the sphere, which reduces the wind pressure on the building.

In particular, in the case of wind pressure from the front, the wind tends to enter the recess through the gap with the sphere, which absorbs the wind pressure, greatly reducing the wind pressure and preventing the building from shaking.

When wind pressure is applied diagonally, the rotation of the sphere becomes particularly intense, and there is little difference in wind speed on the outer surface.
There is no pressure build-up that would cause the exterior wall materials to peel off.

In addition, since no pressure is created on the outer surface, rainwater is prevented from adhering to the roof, allowing the rainwater to flow smoothly without stagnation.

The outer wall material of the second invention also exhibits substantially the same effect as the above-mentioned outer wall material. However, since the sphere rotates in one direction, it is desirable to arrange the outer wall materials so that their axes are perpendicular to the direction in which they receive the wind, thereby promoting the rotation of the sphere.

In addition, the exterior wall material has many gaps between the spheres, and this complex space easily absorbs wind pressure, rainwater, and noise, and these forces are dissipated in the same way as the tetrapod.

Further, the exterior wall materials of any of the inventions are suitable for windbreak walls and sandproof walls in deserts and the like.

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

[Embodiment of the first invention] FIGS. 1 to 5 show one embodiment, in which the outer wall material P is composed of a disc body F and a large number of spheres 3, and the disc body F is composed of a substrate 1 It is composed of a surface plate 2 of a sphere holder.

The base 1 has convex portions 4,5,6 protruding at equal intervals in the vertical and horizontal directions, so that the space surrounded by any four convex portions is formed into four portions 7.
．． It is 8.

The basic shape of the protrusion 4.5.6 is a truncated cone, with a half-notched protrusion 5 on the periphery and a three-quarter-notched protrusion 6 at the corner. Convex portions 4 are arranged inside. Furthermore, each convex portion 4.5.6 is provided with a cutout hole 9 at a location facing the concave portion 7.8. The sphere 3 is inserted into this notch hole 9
The position is held stable because it partially hangs on the surface. In addition, convex hemispheres 10 are integrally formed on the four central convex portions 4, while semi-chipped hemispheres 11 are formed on the two central convex portions 5 of each side, and the corner convex portions are formed integrally with convex hemispheres 10. 6 has a hemisphere with three quarters missing 12
are protruding from each other.

The recesses 7.8 are provided with a circular concave rotary seat 13 at the bottom to hold the sphere 3 at the center, and the four recesses 7 at the center and the three recesses 7 at each corner protrude from the rotary seat 13. It is formed high by the strip 14. Furthermore, a drain hole 15 is provided at the center of each bottom.

The substrate 1 is connected vertically and horizontally (4 x 4 = 16 pieces as a set), but since it has the above structure, the half-cut convex part 5 and hemisphere 11, and the three-quarters part are the convex part 6 and the hemisphere. The body 12 is
By connecting them, they are assembled into a basic shape.

Regarding the connection, dovetail-shaped mortise holes 20 are provided on two adjacent sides of the substrate 1, and mortise holes 20 are inserted into the other two sides from above.
1 are formed in pairs, and the lower end of the tenon hole 20 is cut out, and a claw 22 that hangs on the lower edge is formed in the tenon 21. Projection hole 1
7.18, and an inner flange 24 is formed in the protrusion hole 17 corresponding to the high recess 7. In addition, any four protruding holes 17
．． A hole 25 or a hemisphere 10a through which the hemisphere 10 of the base 1 passes is formed in the center surrounded by the hemisphere 18. Further, a protruding piece 26 is provided at a location corresponding to the tenon 21, and the protruding piece 26 is provided at a location corresponding to the tenon 21.
6 is also formed with a hemisphere 10a.

Moreover, a notch 27 into which a projection piece 26 is fitted is provided at a location corresponding to the tenon hole 20. 36 is a screw hole for fixing to the frame of a building.

Regarding the connection between the base plate 1 and the surface plate 2, a notch hole 28 is provided in the base 1 near the hemisphere 10, a hemisphere 11 for the half-cut, and a hemisphere 12 for the three-quarters cut, respectively. The cutout hole 28 is provided with a claw 29 that hangs under the hemisphere 10, 11, 12. In this way, the claw 29 can be easily inserted into the notch hole 28 along the spherical surface.

The sphere 3 is a hollow body the size of a golf ball, and has dimples formed on its outer surface in the same way as a golf ball to cause air turbulence.

According to the above-mentioned exterior wall material, since it has a pyramid structure in which low spheres 3 that fit in low recesses 8 are arranged around high spheres 3 that fit in high recesses 7, or low hemispheres 10 are arranged, it can withstand strong winds. When exposed to wind, the wind pressure is rationally absorbed and soundproofing properties are exhibited.

In addition, since pressure is released in the recess 7.8 due to the rotation of the sphere 3, placing an adsorption plate below for dirt, dust, nitrogen oxides, sulfides, etc. can absorb the outside air. Suitable for cleaning. Double-sided adhesive tape can be used to install the suction plate.

[Another embodiment of the first invention] Fig. 6 shows an arrangement of a pyramid structure consisting of a large sphere 3a and a medium sphere 3b. Medium spheres 3b are arranged. Looking at this from a different angle, it can be said to be a regular pentagonal arrangement based on the golden ratio.

The Golden Ratio has the property that when it appears in one place, it spreads to other places and rules everywhere. This property is particularly noticeable in regular pentagons.

Figure 7 shows an example of the arrangement of regular pentagons. According to this figure, if you arrange one regular pentagon at the center and five other regular pentagons, a large regular pentagon will be created, so one more large regular pentagon will be formed. It is possible to gradually expand the array of regular pentagons by arranging five other large regular pentagons around the regular pentagon, but gradually larger gaps (blank areas) will appear. .

In the case of this embodiment, since gaps 28, 29 are created, the wind pressure is absorbed more skillfully by the irregularity than in the case of a mere regular arrangement of the spheres 3a, 3b.

Cushions can be inserted into the gaps 28 and 29, or joints for connection to the building can be incorporated. Further, when the gap 29 becomes larger, the spheres 3a and 3b can be incorporated.

FIG. 8 shows the arrangement of the large spheres 3a and medium spheres 3b, in which the diagonal arrangement R of the large spheres 3a is adjusted to the curve of the expected wind turbulence. 30 is a joint.

[Embodiment of the second invention] FIGS. 9 and 10 show an embodiment of the first invention, in which the outer wall material P includes a frame 32 and a large number of shafts 3.
3 and a large number of spheres 3.

The frame 32 has standing pieces 35.35 erected at both ends, and a shaft 33 is installed in three stages between both the standing pieces 35.35.
They are arranged horizontally.

The spheres 3 are inserted into each shaft 33 in a chain and are rotatably supported.

This exterior wall material P is suitable for, for example, a circular dome building, and if the shafts 33 are arranged horizontally, the spherical body 3 will rotate due to the wind blowing up, and the rotation will relieve the wind pressure. In addition, since there are many gaps between the spheres 3 and they are deep and complicated, not only wind pressure but also sound enters there and disappears. Furthermore, rainwater enters the gap and flows downstream along the bottom, but since the wind pressure disappears at the bottom, the rainwater flows smoothly without being hindered by wind pressure.

In addition, in the case of a circular dome, it is desirable that the thickness is 50 mm or less.

Furthermore, since it has very good soundproofing properties, it is suitable for soundproofing walls built on the sides of railways and roads.

Further, in any of the embodiments, since the sphere 3 is hollow, if a large number of holes are provided on the surface of the sphere 30, the soundproofing properties and wind resistance will be further improved.

〔Effect of the invention〕

As explained above, according to the exterior wall material of the first invention, since the spheres are rotatably housed in the recesses and a large number of spheres are exposed on the surface and arranged, they rotate in strong winds and skillfully release wind pressure. In addition, even if the building receives wind pressure from the front, it can withstand the wind pressure without shaking, and even if it receives wind pressure from an angle, it does not cause any pressure relief on the outside, so there is no risk of it peeling off from the building, and it is easy to drain rain. This makes it possible to design inexpensive buildings without using excessive amounts of materials, and
It has excellent effects such as soundproofing.

Moreover, according to the exterior wall material of the second invention, substantially the same effects as the first invention are exhibited, and in particular, by configuring the spheres in multiple layers, there is an effect that the soundproofing performance can be extremely increased.
