  With the recent aging of society, it has become important to ensure safety when an elderly person falls. In buildings, when a person collides with a wall due to a fall or the like, it is considered to be able to reduce the impact from the wall to the person. For this reason, it is required to further improve the shock absorbing function in the shock absorbing building material.

In addition, with the recent aging of society, opportunities to use wheelchairs are increasing. Along with that, it has become a problem that a wheelchair collides with a wall of a building, and a dent or a ridge is formed on the wall surface or the surface is chipped.
In particular, the corners of the wall were problematic because both people and wheelchairs could collide.

In order to improve the shock absorbing function of the shock absorbing building material, it is conceivable to reduce the hardness of the shock absorbing building material so as to easily absorb the shock. However, when the hardness of the shock-absorbing building material is lowered, the surface is easily dimples, wrinkles, and chipped even with a small impact, and the durability is lowered. As described above, it is difficult to improve the shock absorbing function while ensuring the durability of the shock absorbing building material.
Conventional shock-absorbing building materials have an excellent shock-absorbing function and do not easily cause dents, wrinkles, and chips on the surface.

  The present invention can further improve an impact buffering function for mitigating an impact from a wall to an object when an object collides with the wall, and moreover, an impact buffering construction material in which dents, wrinkles and chips are unlikely to occur. It is an issue to provide.

In order to solve the above-mentioned problems, the present inventor has a shock absorbing layer and a protective layer integrated on one surface of the shock absorbing layer, and the shock absorbing layer has a high impact. It has been found that it is effective to use a shock-absorbing construction material using a material that can provide a buffering function, and using a hard material that does not easily generate dents, wrinkles, or chips in the protective layer.
And this inventor paid attention to the material used for a shock absorption layer and a protective layer, and repeated earnest examination.

As a result, it has at least two layers: a shock absorbing layer made of a foamed resin having a specific hardness and expansion ratio, and a protective layer made of a semi-rigid / hard resin having a specific hardness and thickness, and these two layers are coextruded. The present invention was conceived by finding out that the shock-absorbing building material should be made.
That is, the present invention relates to the following inventions.

  (1) A durometer having a durometer hardness (JIS K7215) of A80 or less and a foam absorbing resin having a foaming ratio of 1.5 to 4 times, and a durometer disposed on one surface of the shock absorbing layer. A protective layer made of a resin having a hardness (JIS K7215) of D30 to D100 and a thickness of 0.3 to 1.5 mm, and the shock absorbing layer and the protective layer are coextruded. A shock-absorbing building material characterized by comprising:

(2) The reinforcing layer is disposed on the other surface of the shock absorbing layer, has a durometer hardness (JIS K7215) of D50 to D100, and is made of a resin having a thickness of 0.5 mm or more. The shock-absorbing building material according to (1), wherein the shock-absorbing layer and the protective layer are co-extruded.
(3) The durometer hardness (JIS K7215) is D50 to D100, and is attached to a reinforcing member made of a resin having a thickness of 0.5 mm or more with the surface opposite to the protective layer facing. The shock-absorbing building material according to (1) or (2), characterized in that it is characterized.

(4) The shock absorbing construction material according to any one of (1) to (3), wherein the shock absorbing layer has a thickness of 1 to 30 mm.

“First Embodiment”
FIG. 1 is a schematic cross-sectional view for explaining a state in which an example of the shock-absorbing building material of the present invention is attached to a wall. In FIG. 1, the code | symbol 10 shows the shock-absorbing building material and the code | symbol 20 has shown the wall.
The wall 20 to which the shock-absorbing building material 10 shown in FIG. 1 is attached is provided in the room of a house. The wall 20 includes a pillar 24 made of wood or the like, a gypsum board 23 fixed to the pillar 24, and a cloth 22 attached to the surface of the gypsum board 23. A protruding corner 20a (corner portion) is formed on the wall 20 shown in FIG.

  1 includes a shock absorbing layer 1 made of foamed resin, and a protective layer 2 made of a semi-rigid resin or a hard resin disposed on one surface (outer surface) of the shock absorbing layer 1. And a reinforcing layer 3 made of a hard resin disposed on the other surface (inner surface) of the shock absorbing layer 1. An impact buffering building material 10 shown in FIG. 1 is obtained by co-extrusion of a reinforcing layer 3, an impact absorbing layer 1, and a protective layer 2. As shown in FIG. 1, the shock absorbing layer 1 is formed so as to fill a region surrounded by the reinforcing layer 3 and the protective layer 2.

As shown in FIG. 1, the shock-absorbing building material 10 is installed so as to cover the protruding corner 20 a of the wall 20.
The shock-absorbing building material 10 has a shape obtained by bending a plate-like long member with the protective layer 2 facing outward so that a valley 5 extending in the length direction is formed. In the shock-absorbing building material 10 shown in FIG. 1, the valley 5 is formed at a substantially central position in the width direction. Accordingly, the distance from the valley 5 to the respective edge portions 11 and 12 in the width direction is the same. The length and width of the shock-absorbing building material 10 can be appropriately determined according to the conditions of the place where the shock-absorbing building material 10 is installed, the main purpose of installing the shock-absorbing building material 10, and the like.

  The edge portions 11 and 12 in the width direction of the shock-absorbing building material 10 shown in FIG. 1 have an inclined surface with a circular arc in cross section when the thickness of the shock-absorbing layer 1 is gradually reduced. ing. As a result, compared with the case where the edge portions 11 and 12 in the width direction of the shock-absorbing building material 10 are perpendicular to the surface (inner surface) opposite to the protective layer 2 of the shock absorbing layer 1, The effect shown is obtained. That is, it is possible to mitigate the impact from the shock-absorbing building material 10 to the object when the object hits the shock-buffering building material 10. Moreover, it can prevent that the shock-absorbing building material 10 overhanging from the wall 20 is obstructive. Furthermore, a good appearance can be obtained.

  Moreover, as for the impact buffering building material 10 shown in FIG. 1, the surface on the opposite side to the trough 5 is made into the shape of circular arc view of a cross section. For this reason, for example, compared with the case where the surface opposite to the valley 5 has a right-angled cross-sectional shape, the object is placed on the shock-absorbing building material 10 installed at the protruding corner 20a (corner portion) of the wall 20. In the case of a collision, the impact from the shock absorbing building material 10 to the object can be more effectively mitigated.

  The shock absorbing layer 1 is made of a foamed resin having a durometer hardness (JIS K7215) of A80 or less and a foaming ratio of 1.5 to 4 times. The shock absorbing layer 1 is excellent in elasticity because the durometer hardness and the expansion ratio of the foamed resin are within the above ranges. For this reason, when an object collides with the wall 20 to which the shock-absorbing building material 10 is attached, the impact from the wall 20 to the object can be sufficiently mitigated. In order to further improve the shock absorbing function of the shock absorbing building material 10, the durometer hardness of the shock absorbing layer 1 is more preferably A30 to A60, and the expansion ratio of the foamed resin is 2-3. More preferably, it is double.

  The material used for the shock absorbing layer 1 is not particularly limited as long as the durometer hardness and the expansion ratio of the foamed resin are within the above ranges. For example, the material used for the shock absorbing layer 1 is a material in which 1 to 10 parts by weight of a thermally expandable microballoon is mixed with 100 parts by weight of a resin such as an olefin elastomer, a styrene elastomer, or a soft vinyl chloride resin. be able to.

  The thickness of the shock absorbing layer 1 is preferably 1 to 30 mm. When the thickness of the shock absorbing layer 1 is 1 mm or more, a sufficient shock absorbing function as the shock absorbing building material 10 is obtained. In order to further improve the shock absorbing function of the shock absorbing building material 10, the thickness of the shock absorbing layer 1 is more preferably 3 mm or more. Moreover, when the thickness of the shock absorbing layer 1 is 30 mm or less, it is preferable because the overhanging dimension of the shock absorbing building material 10 from the wall 20 becomes too large and can be prevented from becoming an obstacle.

  The protective layer 2 is made of a semi-rigid resin or a hard resin having a durometer hardness (JIS K7215) of D30 to D100 and a thickness of 0.3 to 1.5 mm. By setting the durometer hardness of the protective layer 2 to D30 or more and the thickness to 0.3 mm or more, it is possible to sufficiently prevent the surface of the protective layer 2 from being depressed, wrinkled or chipped, and to obtain excellent durability. It is done. In order to further improve the durability of the shock-absorbing building material 10, the durometer hardness of the protective layer 2 is more preferably D50 or more, and the thickness is more preferably 0.5 mm or more.

  Further, when the durometer hardness of the protective layer 2 is set to D100 or less and the thickness is set to 1.5 mm or less, when the shock absorbing construction material 10 receives an impact from the protective layer 2 side of the shock absorbing layer 1, the protective layer 2 bends following the deformation of the shock absorbing layer 1 due to the shock, and absorbs the shock together with the shock absorbing layer 1. In order to further improve the followability of the protective layer 2 against deformation of the shock absorbing layer 1 and improve the shock absorbing function of the shock absorbing construction material 10, the durometer hardness of the protective layer 2 is set to D80 or less, and the thickness is More preferably, it is 1 mm or less.

  The material of the protective layer 2 is not particularly limited as long as the durometer hardness and thickness are in the above ranges. For example, as a material used for the protective layer 2, polypropylene resin, polyethylene resin, vinyl chloride resin (including semi-rigid), polystyrene resin, ABS resin (acrylonitrile, butadiene, styrene copolymer resin), ASA (acrylonitrile styrene acrylate) resin An acrylic resin, an olefin-based elastomer, a styrene-based elastomer, or the like can be used.

  The above-described resin that can be used as the material of the protective layer 2 is preferable because it is a resin having high adhesion to the material used for the above-described shock absorbing layer 1. When the adhesion between the protective layer 2 and the shock absorbing layer 1 is excellent, the followability of the protective layer 2 against deformation of the shock absorbing layer 1 is improved, so that the shock absorbing function of the shock absorbing building material 10 is improved. Moreover, if the adhesiveness between the protective layer 2 and the shock absorbing layer 1 is excellent, the durability is improved.

  The reinforcing layer 3 is made of a hard resin having a durometer hardness (JIS K7215) of D50 to D100 and a thickness of 0.5 mm or more. When the durometer hardness of the reinforcing layer 3 is set to D50 or more and the thickness is set to 0.5 mm or more, when the shock absorbing construction material 10 receives an impact from the protective layer 2 side of the shock absorbing layer 1, the shock absorbing construction Breakage of the wall 20 disposed in the lower layer of the dressing 10 can be prevented. In order to more effectively prevent damage to the wall 20 disposed in the lower layer of the shock-absorbing building material 10, the durometer hardness of the reinforcing layer 3 is more preferably D70 or more, and the thickness is 2 mm. More preferably. The thickness of the reinforcing layer 3 is more preferably 5 mm or less so that the overhanging dimension of the shock absorbing construction material 10 from the wall 20 does not become too large. Moreover, the choice of the material of the reinforcement layer 3 can be increased because the durometer hardness of the reinforcement layer 3 shall be D100 or less.

The material of the reinforcing layer 3 is not particularly limited as long as the durometer hardness and thickness are in the above ranges. For example, as a material used for the reinforcing layer 3, polypropylene resin, polyethylene resin, vinyl chloride resin, polystyrene resin, ABS resin, ASA resin, acrylic resin, or the like can be used. Moreover, since these resin which can be used as a material of the reinforcement layer 3 is resin with high adhesiveness with the material used for the impact-absorbing layer 1 mentioned above, it is preferable. When the adhesion between the reinforcing layer 3 and the shock absorbing layer 1 is excellent, the durability of the shock-absorbing building material 10 is improved.
The material of the reinforcing layer 3 may be the same as the material of the protective layer 2 or may be different.

  Moreover, the shock-absorbing building material 10 shown in FIG. 1 is one in which the reinforcing layer 3, the shock absorbing layer 1, and the protective layer 2 are co-extruded and integrated. For this reason, the adhesion between the reinforcing layer 3 and the shock absorbing layer 1 and the adhesion between the protective layer 2 and the shock absorbing layer 1 are excellent. For this reason, the shock-absorbing building material 10 has excellent durability.

  As a method of coextrusion molding of the reinforcing layer 3, the shock absorbing layer 1 and the protective layer 2 when manufacturing the shock absorbing building material 10 shown in FIG. 1, a conventionally known method can be used. The conditions for coextrusion molding can be appropriately determined according to the material and thickness of each layer.

Moreover, any method may be used as a method for installing the shock-absorbing building material 10 shown in FIG. For example, the shock-absorbing building material 10 may be fixed to the surface of the wall 20 using screws (screws) or the like. Further, since the shock-absorbing building material 10 shown in FIG. 1 is made of resin and is lightweight, it can be easily installed by using a method of bonding to the surface of the wall 20 or a method using a double-sided tape. When the shock-absorbing building material 10 is bonded to the surface of the wall 20, a bonding member such as a screw is not exposed on the surface of the protective layer 2 and a good appearance is obtained, which is preferable.
Furthermore, the surface of the protective layer 2 of the shock-absorbing building material 10 may be colored or printed as necessary. By this, for example, attention can be drawn so as not to collide with the shock-absorbing building material 10, and the appearance can be improved.

  In the shock-absorbing building material 10 shown in FIG. 1, when an impact is received from the protective layer 2 side of the shock absorbing layer 1, the protective layer 2 is deformed along with the deformation of the shock absorbing layer 1 together with the shock absorbing layer 1. . Therefore, the shock is absorbed by the shock absorbing layer 1 and the protective layer 2. More specifically, the impact received from the protective layer 2 side of the shock absorbing layer 1 is dispersed in the surface direction by the protective layer 2 having a hardness higher than that of the shock absorbing layer 1, while the shock absorbing layer 1 has a thickness direction. Communicated. As a result, in the shock-absorbing building material 10 shown in FIG. 1, the stress due to the shock is less likely to concentrate on a part of the shock-absorbing layer 1, and the shock-absorbing ability of the shock-absorbing layer 1 can be used efficiently. Due to such a synergistic effect of the shock absorbing layer 1 and the protective layer 2, the shock absorbing construction material 10 shown in FIG. 1 can provide an excellent shock absorbing function. As a result, in the shock-absorbing building material 10 shown in FIG. 1, for example, when a person collides with the wall 20 to which the shock-absorbing building material 10 is attached due to a fall or the like, the shock from the wall 20 to the person is sufficient. Can be relaxed.

  Further, in the shock-absorbing building material 10 shown in FIG. 1, since the impact is dispersed in the surface direction by the protective layer 2, it is possible to prevent a deep recess that cannot be recovered from being formed in a part of the shock-absorbing layer 1 due to the impact. Is done. Therefore, the shock-absorbing building material 10 is difficult to form a depression on the surface after receiving the impact. 1 absorbs the impact received from the protective layer 2 side of the shock absorbing layer 1 and then reacts against the impact of the protective layer 2 having high hardness, so that The surface shape is easily restored to the original shape. In addition, since the protective layer 2 has a sufficiently high hardness, wrinkles and chips are less likely to be formed as compared with the protective layer 2 consisting only of the shock absorbing layer 1. Therefore, the shock-absorbing building material 10 shown in FIG. 1 is excellent in durability and can maintain a good appearance over a long period of time.

  Moreover, since the shock-absorbing building material 10 shown in FIG. 1 has the reinforcing layer 3, it receives an impact from the protective layer 2 side of the shock absorbing layer 1 and is absorbed by the protective layer 2 and the shock absorbing layer 1. It is possible to prevent the structure of the wall 20 disposed in the lower layer of the shock-absorbing building material 10 from being damaged when an impact that has not occurred reaches the reinforcing layer 3. Therefore, in the shock-absorbing building material 10 shown in FIG. 1, for example, even when a hard object such as a wheelchair hits the wall 20 to which the shock-buffering building material 10 is attached, the wall 20 can be prevented from being damaged.

“Second Embodiment”
FIG. 2 is a schematic cross-sectional view for explaining a state in which another example of the shock absorbing construction material of the present invention is attached to a wall. In FIG. 2, the same members as those in the first embodiment shown in FIG. In FIG. 2, the code | symbol 10a shows the shock-absorbing building material, and the code | symbol 21 has shown the wall.

  The wall 21 to which the shock-absorbing building material 10a shown in FIG. 2 is attached is provided inside the house. The wall 21 includes a pillar 24 made of wood or the like, a gypsum board 23 fixed to the pillar 24, and a cloth 22 attached to the surface of the gypsum board 23. Also in the wall 21 shown in FIG. 2, a protruding corner 20a (corner portion) is formed. However, unlike the wall 20 shown in FIG. 1, the wall 21 shown in FIG. 2 is provided with an impact buffering building material 10a in place of the gypsum board 23 installed at the protruding corner 20a.

  2 is installed so as to cover the protruding corner 20a of the wall 21. The edge portions 11a and 12a in the width direction of the shock absorbing construction material 10a shown in FIG. 2 are different from the shock absorbing construction material 10 shown in FIG. Surface). And each edge part 11a, 12a of the width direction of the impact buffering building material 10a is arrange | positioned facing the side surface of the gypsum board 23, respectively. Moreover, the thickness of the shock-absorbing building material 10 a shown in FIG. 2 is substantially the same as the thickness of the gypsum board 23. As a result, the outer surface of the gypsum board 23 and the surface on the protective layer 2 side of the shock-absorbing building material 10a are arranged on substantially the same plane. Thereby, in the wall 21 shown in FIG. 2, the cloth 22 is stuck on the surface on the protective layer 2 side of the shock-absorbing building material 10a continuously from the outer surface of the gypsum board 23. That is, the protective layer 2 constituting the shock-absorbing building material 10a functions as a cloth pasting base.

  In the wall 21 shown in FIG. 2, an impact buffering building material 10 a is installed inside the wall 21. Therefore, in the wall 21 shown in FIG. 2, the effect by installing the shock-absorbing building material 10a can be obtained without projecting the shock-absorbing building material 10a toward the outside of the wall 21. Therefore, in the wall 21 shown in FIG. 2, the shock-absorbing building material 10 a does not get in the way, and the shock-buffering building material 10 a does not affect the appearance of the wall 21.

  Moreover, any method may be used as the installation method of the shock-absorbing building material 10a shown in FIG. For example, the shock-absorbing building material 10a may be fixed to the surface of the wall 21 using a screw or the like. In addition, in the wall 21 shown in FIG. 2, since the shock-absorbing building material 10a is installed inside the wall 21, a bonding member such as a screw (screw) is provided on the surface of the protective layer 2 of the shock-buffering building material 10a. Exposure does not affect the appearance.

  The shock-absorbing building material 10a shown in FIG. 2 is the same as the shock-absorbing building material 10 shown in FIG. 1, and the protection disposed on the shock absorbing layer 1 and one surface (outer surface) of the shock absorbing layer 1. It has the layer 2 and the reinforcement layer 3 arrange | positioned at the other surface (inner surface) of the shock absorption layer 1. Moreover, the impact buffering building material 10a shown in FIG. 2 is formed by coextrusion molding of the reinforcing layer 3, the shock absorbing layer 1, and the protective layer 2, similarly to the shock buffering building material 10 shown in FIG. is there.

  Therefore, also in the shock absorbing construction material 10a shown in FIG. 2, the shock absorbing layer 1 when receiving an impact from the protective layer 2 side of the shock absorbing layer 1 as in the shock absorbing building material 10 shown in FIG. It is difficult for stress due to impact to concentrate on a part of the surface, and the impact absorbing ability of the impact absorbing layer 1 can be used efficiently. Therefore, even in the shock-absorbing building material 10a shown in FIG. 2, for example, when a person hits the wall 21 to which the shock-absorbing building material 10a is attached due to a fall or the like, the shock from the wall 21 to the person is sufficient. Can be relaxed.

  Also, the shock-absorbing building material 10a shown in FIG. 2 is less likely to form a depression on the surface after receiving the shock, like the shock-absorbing building material 10 shown in FIG. 2 also absorbs an impact received from the protective layer 2 side of the shock absorbing layer 1 and then protects it with high hardness in the same manner as the shock absorbing building material 10 shown in FIG. Due to the reaction force against the impact of the layer 2, the surface shape on the protective layer 2 side is easily restored to the original shape. Therefore, the shock-absorbing building material 10a shown in FIG. 2 can maintain a good appearance over a long period of time.

  Moreover, since the shock-absorbing building material 10a shown in FIG. 2 has the reinforcement layer 3 similarly to the shock-buffering building material 10 shown in FIG. 1, an impact is applied from the protective layer 2 side of the shock absorbing layer 1. When received, damage to the structure of the wall 21 arranged in the lower layer of the shock-absorbing building material 10a can be effectively prevented.

“Third Embodiment”
FIG. 3 is a schematic cross-sectional view for explaining a state in which another example of the shock absorbing construction material of the present invention is attached to a wall. In FIG. 3, the same members as those in the first embodiment shown in FIG. In FIG. 3, the code | symbol 10b shows the shock-absorbing building material, and the code | symbol 27 has shown the wall.

  The wall 27 to which the shock-absorbing building material 10b shown in FIG. 3 is attached is provided inside the house. The wall 27 includes a base material 25 made of wood or the like, a gypsum board 23 fixed to the base material 25, and a cloth 22 attached to the surface of the gypsum board 23. A sash 26 is attached to the wall 27. Also in the wall 27 shown in FIG. 3, a protruding corner 20a (corner portion) is formed.

  3 is installed so as to cover the protruding corner 20a of the wall 27. As shown in FIG. 3, the shock absorbing building material 10 b is attached to the base material 25 and the gypsum board 23. As shown in FIG. 3, a flange (angle) of a sash 26 is attached to the shock-absorbing building material 10b. The shock absorbing construction material 10b functions as a window frame.

  The impact buffering building material 10b shown in FIG. 3 protects the plate-like long member so that the valley 5 extending in the length direction is formed, like the shock buffering building material 10 shown in FIG. The layer 2 is bent outward. In the shock-absorbing building material 10 shown in FIG. 1, the distance between the valley 5 of the shock-buffering building material 10 and both edges in the width direction is substantially the same. However, in the shock-absorbing building material 10b shown in FIG. 3, unlike the shock-buffering building material 10 shown in FIG. 1, the distance L1 between the valley 5 of the shock-buffering building material 10b and one edge 12b, and the valley 5 And the distance L2 between the other edge 11b is different.

  Further, in the shock-absorbing building material 10b shown in FIG. 3, the edge portions 11b and 12b in the width direction are substantially perpendicular to the surface (inner surface) opposite to the protective layer 2 of the shock-absorbing layer 1. And the edge part 12b by the side of the sash 26 of the width direction of the shock-absorbing building material 10b is arrange | positioned facing the outer wall (not shown).

  The shock-absorbing building material 10b shown in FIG. 3 is the same as the shock-absorbing building material 10 shown in FIG. 1, and the protection disposed on the shock absorbing layer 1 and one surface (outer surface) of the shock absorbing layer 1. It has the layer 2 and the reinforcement layer 3 arrange | positioned at the other surface (inner surface) of the shock absorption layer 1. Moreover, the impact buffering building material 10b shown in FIG. 3 is formed by coextrusion molding of the reinforcing layer 3, the shock absorbing layer 1, and the protective layer 2 in the same manner as the impact buffering building material 10 shown in FIG. is there.

  Therefore, also in the shock absorbing construction material 10b shown in FIG. 3, the shock absorbing layer 1 when receiving an impact from the protective layer 2 side of the shock absorbing layer 1 similarly to the shock absorbing building material 10 shown in FIG. It is difficult for stress due to impact to concentrate on a part of the surface, and the impact absorbing ability of the impact absorbing layer 1 can be used efficiently. Therefore, even in the shock-absorbing building material 10b shown in FIG. 3, for example, when a person hits the wall 27 to which the shock-absorbing building material 10b is attached due to a fall or the like, the shock from the wall 27 to the person is sufficient. Can be relaxed.

  Also, the shock-absorbing building material 10b shown in FIG. 3 is less likely to form a depression on the surface after receiving the shock, similarly to the shock-buffering building material 10 shown in FIG. 3 also absorbs an impact received from the protective layer 2 side of the shock absorbing layer 1 and then protects it with high hardness, similarly to the shock absorbing building material 10 shown in FIG. Due to the reaction force against the impact of the layer 2, the surface shape on the protective layer 2 side is easily restored to the original shape. In addition, since the protective layer 2 has a sufficiently high hardness, wrinkles and chips are less likely to be formed as compared with the protective layer 2 consisting only of the shock absorbing layer 1. Therefore, the shock-absorbing building material 10b shown in FIG. 3 can maintain a good appearance over a long period of time.

  Moreover, since the shock-absorbing building material 10b shown in FIG. 3 has the reinforcing layer 3 similarly to the shock-buffering building material 10 shown in FIG. 1, an impact is applied from the protective layer 2 side of the shock absorbing layer 1. When it receives, damage to the structure of the wall 27 arrange | positioned in the lower layer of the shock-absorbing building material 10b can be prevented effectively.

"Other examples"
The shock-absorbing building material of the present invention is not limited to the above-described embodiment. For example, the shock-absorbing building materials shown in FIGS. 4 (a) to 4 (f) may be used.
Fig.4 (a) is a schematic diagram for demonstrating the other example of the shock-absorbing building material of this invention. The shock absorbing construction material 10c shown in FIG. 4 (a) is different from the shock absorbing construction material 10 shown in FIG. It is only where the extending groove is formed.

  In some cases, irregularities are formed in the protruding corner (corner portion) of the wall where the shock-absorbing building material 10c is to be installed, for example, due to an object colliding and deforming. When the shock-absorbing building material 10c is installed so as to cover such a protruding corner, the shock-buffering building material 10c and the wall may not be brought into close contact with each other due to the unevenness present at the protruding corner.

Unless the shock-absorbing building material 10c is installed in close contact with the wall, the stress due to the shock from the protective layer 2 side of the shock-absorbing layer 1 absorbed by the shock-buffering building material 10b is concentrated on a part of the wall. There is a fear. For this reason, there exists a possibility that the function which prevents damage to the structure of the wall by the shock-absorbing building material 10c may not be obtained sufficiently.
Moreover, if the shock-absorbing building material 10c is not installed in close contact with the wall, the shock-absorbing building material 10c may be distorted and attached, and the appearance may deteriorate. In addition, if the shock-absorbing building material 10c is not installed in close contact with the wall, a sufficient bonding force between the shock-buffering building material 10c and the wall cannot be obtained, and the shock-buffering building material 10c is likely to be detached from the wall. There is.

  In the shock-absorbing building material 10c shown in FIG. 4 (a), the trough 51 is formed with a groove extending in the lengthwise direction in an arc shape when viewed from the cross section. When the shock-absorbing building material 10c is installed so as to cover the corner, the protrusion and depression of the protruding corner enter the groove formed in the valley 51. Therefore, the shock-absorbing building material 10c can be attached in close contact with the wall. Therefore, even if the shock-absorbing building material 10c is attached to a wall having unevenness at the protruding corner, it can effectively prevent damage to the wall structure. In addition, it is possible to prevent the shock-absorbing building material 10c from being distorted and attached and the bonding force between the shock-buffering building material 10c and the wall from becoming insufficient.

Moreover, in embodiment mentioned above, although what gave the reinforcement layer, the shock absorption layer, and the protective layer was mentioned as an example, in the shock-absorbing building material of this invention, as shown in FIG.4 (b). The reinforcing layer may not be provided.
The shock-absorbing building material 10d shown in FIG. 4 (b) has a shock-absorbing layer 1 and a protective layer 2 disposed on one surface (outer surface) of the shock-absorbing layer 1. Moreover, FIG.4 (b) shock-absorbing building material 10d is a thing formed by coextrusion molding of the impact-absorbing layer 1 and the protective layer 2. FIG.

  Also in the shock-absorbing building material 10d shown in FIG. 4 (b), the shock-absorbing layer when the shock-absorbing building material 10 shown in FIG. It is difficult for stress due to impact to concentrate on a part of 1, and the impact absorbing ability of the impact absorbing layer 1 can be used efficiently. Therefore, in the shock absorbing construction material 10d shown in FIG. 4 (b), for example, when a person hits the wall to which the shock absorbing construction material 10d is attached due to a fall or the like, the impact from the wall to the person is applied. It can be relaxed enough.

  Also, the shock-absorbing building material 10d shown in FIG. 4 (b) is less likely to form a depression on the surface after receiving the shock, like the shock-absorbing building material 10 shown in FIG. Further, the shock absorbing construction material 10d shown in FIG. 4 (b) also has a hardness after absorbing the impact received from the protective layer 2 side of the shock absorbing layer 1, similarly to the shock absorbing construction material 10 shown in FIG. Due to the reaction force against the impact of the high protective layer 2, the surface shape on the protective layer 2 side is easily restored to the original shape. In addition, since the protective layer 2 has a sufficiently high hardness, wrinkles and chips are less likely to be formed as compared with the protective layer 2 consisting only of the shock absorbing layer 1. Therefore, the shock-absorbing building material 10d shown in FIG. 4 (b) can maintain a good appearance for a long time.

Moreover, as shown in FIG.4 (c), the shock-absorbing building material of this invention may have the impact-absorbing layer 1a, the protective layer 2a, and the reinforcement member 4. As shown in FIG.

It is the same as the shock absorbing building material 10d.

  In the shock absorbing layer 1a in the shock absorbing construction material 10e shown in FIG. 4 (c), along the edge in the width direction, on the surface (inner surface) opposite to the protective layer 2a, Grooves 1b and 1b for accommodating the engaging portion 4a are provided. FIG.4 (d) is the enlarged view schematic diagram which showed a part of impact buffer building material 10e shown in FIG.4 (c). The grooves 1b and 1b are formed by making the shape of the mold used when the cover member 13 is formed into a predetermined shape.

  Moreover, the protective layer 2a of the shock absorbing construction material 10e shown in FIG. 4C is continuously formed from the outer surface of the shock absorbing layer 1a to a part of the inner surface of the shock absorbing layer 1a. . Further, as shown in FIG. 4D, the protective layer 2a formed on the inner surface of the shock absorbing layer 1a is formed from the inner surface of the shock absorbing layer 1a in the grooves 1b and 1b of the shock absorbing layer 1a. It extends and terminates to form protrusions 2b and 2b. The protrusions 2b and 2b are formed by making the shape of the mold used when the cover member 13 is formed into a predetermined shape.

  And in the shock-absorbing building material 10e, as shown in FIG.4 (c) and FIG.4 (d), the processus | protrusion which consists of the groove | channels 1b and 1b provided in the shock absorption layer 1a, and a part of protective layer 2a 2b and 2b function as a receiving member into which an engaging portion 4a of a reinforcing member 4 described later is detachably fitted. The grooves 1b and 1b and the protrusions 2b and 2b may be formed continuously over the entire length in the length direction of the shock-absorbing building material 10e, or are formed intermittently only in a part of the length direction. May be.

  The central part in the width direction of the reinforcing member 4 has a shape that conforms to the inner shape of the shock absorbing layer 1a. As shown in FIG. 4 (d), engaging portions 4a and 4a are provided at the edge in the width direction of the reinforcing member 4 so as to stand up toward the shock absorbing layer 1a in a cross-sectional view and whose ends extend outward. Is provided. The engaging portions 4a and 4a are provided at positions where they are opposed to the grooves 1b and 1b and the protrusions 2b and 2b. The engaging portions 4a and 4a may be formed only at a part of the position arranged facing the grooves 1b and 1b and the protrusions 2b and 2b, or opposed to the grooves 1b and 1b and the protrusions 2b and 2b. It may be formed over the entire length of the position. Moreover, the hole which can be used when attaching the reinforcement member 4 to a wall may be provided in the reinforcement member 4 as needed.

  The reinforcing member 4 is made of a hard resin having a durometer hardness (JIS K7215) of D50 to D100 and a thickness (thickness of a region where no engaging portion is formed) of 0.5 mm or more. When the durometer hardness of the reinforcing member 4 is set to D50 or more and the thickness is set to 0.5 mm or more, when the impact is received from the protective layer 2 side of the shock absorbing layer 1, it is disposed in the lower layer of the shock absorbing construction material 10e. Can prevent damage to the walls. In order to further improve the protection function for preventing the damage of the wall disposed in the lower layer of the shock-absorbing building material 10e, the durometer hardness of the reinforcing member 4 is more preferably D70 or more, and the thickness is More preferably, it is 2 mm or more. The thickness of the reinforcing member 4 is more preferably 5 mm or less so that the overhanging dimension of the shock absorbing construction material 10e from the wall does not become too large. Moreover, the choice of the material of the reinforcement member 4 can be increased because the durometer hardness of the reinforcement member 4 shall be D100 or less.

The material of the reinforcing member 4 is not particularly limited as long as the durometer hardness and thickness are in the above ranges. For example, as a material used for the reinforcing member 4, polypropylene resin, polyethylene resin, vinyl chloride resin, polystyrene resin, ABS resin, ASA resin, acrylic resin, or the like can be used.
The material of the reinforcing member 4 may be the same as or different from the material of the protective layer 2a.

Even if the member is exposed, the appearance is not affected.
Thereafter, as shown in FIGS. 4C and 4D, the engaging portions 4a and 4a of the reinforcing member 4 are received by the cover member 13 in which the shock absorbing layer 1a and the protective layer 2a are integrated. The shock-absorbing building material 10e can be installed on the wall by being fitted into the member.

Since the shock-absorbing building material 10e shown in FIG. 4 (c) has the reinforcing member 4, when receiving an impact from the protective layer 2a side of the shock-absorbing layer 1a, the lower layer of the shock-buffering building material 10e It can prevent effectively that the structure of the wall arrange | positioned in is damaged.
Moreover, since the cover member 13 formed by integrating the shock absorbing layer 1a and the protective layer 2a is detachably attached to the reinforcing member 4, the reinforcing member 4 is fixed to the mounting position of the shock absorbing construction material 10e. Then, using the method of attaching the cover member 13, the shock-absorbing construction material 10e can be reliably and easily installed on the wall with an excellent appearance. Moreover, since the cover member 13 formed by integrating the shock absorbing layer 1a and the protective layer 2a is detachably attached to the reinforcing member 4, when the cover member 13 is deteriorated, the cover member 13 is replaced. can do.

Moreover, as shown in FIG. 6, the shock-absorbing building material 10g is installed so as to cover the protruding corner 20a (corner portion) of the wall.

  The shock-absorbing building material 10g shown in FIG. 6 and the shock-absorbing building material 10a shown in FIG. 2 are made of the same material and have different shapes. Hereinafter, the shape of the shock-absorbing building material 10g will be described in detail.

  The shock-absorbing building material 10g includes a shock-absorbing layer 15 that is substantially fan-shaped in cross section, a protective layer 52, and a reinforcing layer 35. The protective layer 52 is formed so as to cover the outer surface of the shock absorbing layer 15 and a surface of the edge of the shock absorbing layer 15 continuously from the cloth pasting base portion 25a. 15 protective layers 52 and side surface portions 25b disposed substantially perpendicular to the opposite surface (inner surface). As shown in FIG. 6, the side surface portion 25 b is disposed to face the side surface of the gypsum board 23.

  The cloth pasting base portion 25a shown in FIG. 6 is preferably subjected to a surface treatment in order to improve the adhesion to the cloth 22 and / or the cloth base adjusting material (putty). As the surface treatment, a conventionally known technique can be used and is not particularly limited. Specifically, the surface treatment includes notching treatment for forming a plurality of line-shaped irregularities and / or primer treatment for applying a primer.

The cavity 45 has a function of preventing damage to the structure of the wall disposed in the lower layer of the shock-absorbing building material 10g when receiving an impact from the cross-bonding base portion 25a side of the shock-absorbing layer 15. Moreover, since the impact buffering building material 10g shown in FIG. 6 is a thing in which the cavity 45 is formed by fixing to a wall, the protruding corner 20a (the corner of the pillar 24 in FIG. 6) is distorted. Even if there is an unevenness, the shock-absorbing building material 10g can be installed with high accuracy.

Any method may be used as a method of installing the shock-absorbing building material 10g shown in FIG. For example, the attaching portion 35c of the reinforcing layer 35 may be fixed to the pillar 24 which is a structural member of the wall using screws or the like, or the attaching portion 35c of the reinforcing layer 35 may be fixed to the pillar 24 using an adhesive.

A concave portion 36c is provided in a portion of the wall of the corner portion 36b that faces the protruding corner 20a (the corner of the pillar 24 in FIG. 7). By providing the recess 36c, the shock-absorbing building material 10h can be installed with high accuracy even if the protruding corner 20a of the wall is distorted or uneven. Therefore, the shock-absorbing building material 10h has a good fit and a good wall finish.

  As shown in FIG. 7, the thickness of the cross-bonding base portion 36 a of the reinforcing layer 36 disposed opposite to the gypsum board 23 is substantially the same as the thickness of the gypsum board 23 at one edge of the shock-absorbing building material 10 h. It is said that. Moreover, in the other edge part of the shock-absorbing building material 10h, the total dimension of the side part 26b arranged opposite to the gypsum board 23 and the corner part 36b of the reinforcing layer 36 is substantially the same as the thickness of the gypsum board 23.

As a result, the outer surface of the gypsum board 23, the surface of the cloth pasting base portion 36a of the reinforcing layer 36, and the surface of the cross pasting base portion 26a of the protective layer 26 are arranged on substantially the same plane. Thus, in the wall shown in FIG. 7, the cloth 22 is formed on the surface of the cloth pasting base portion 36 a of the reinforcing layer 36 and the cloth pasting base portion 26 a of the protective layer 26 continuously from the outer surface of the gypsum board 23. It is pasted.

  The surface of the cloth pasting base portion 36a of the reinforcing layer 36 and / or the cross pasting base portion 26a of the protective layer 26 is the same as the cloth pasting base portion 25a of the impact buffering building material 10g shown in FIG. In order to improve the adhesiveness with the cloth substrate adjustment material (putty), it may be surface-treated.

  In addition, the balance between the dimension of the side face part 26b arranged opposite to the gypsum board 23 and the dimension of the corner part 36b of the reinforcing layer 36 at the other edge part of the shock absorbing construction material 10h is particularly limited. Instead, it can be determined appropriately according to the thickness dimension of the gypsum board 23 and the like.

  Moreover, any method may be used as an installation method of the impact buffering building material 10h shown in FIG. For example, the shock-absorbing building material 10h may be fixed to the pillar 24, which is a structural member of the wall, using a screw that penetrates the shock-absorbing building material 10h, or the shock-absorbing building material 10h using an adhesive.

The protective layer 27 constituting the shock-absorbing building material 10i shown in FIG. 8 has a function as a cloth pasting base similarly to the protective layer 2 constituting the shock-absorbing building material 10a shown in FIG. However, the shock-absorbing building material 10i shown in FIG. 8 has no reinforcing layer, and is formed by co-extrusion of the shock absorbing layer 17 and the protective layer 27. Further, the impact buffering building material 10h shown in FIG. 8 is installed so as to cover the protruding corner 20a (corner portion) of the wall through the non-combustible base material 37.

  The shock-absorbing building material 10 i has a shock-absorbing layer 17 and a protective layer 27 that are substantially fan-shaped in cross-section. The protective layer 27 is formed so as to cover the outer surface of the shock absorbing layer 17 and the surface of the edge of the shock absorbing layer 17 continuously from the cloth pasting base portion 27a.
