Description

  The present specification discloses a building material developed for the pin net method and a pin net method using the building material.

A tile or finishing material may be attached to the surface of the housing via a mortar layer, or the surface of the mortar layer may be painted. Due to aging, tiles, finishing materials or mortar layers may peel off from the surface of the enclosure. In the present specification, those which may peel off and fall are referred to as existing finishing layers.
A pin net method has been developed to prevent the existing finish layer from falling. In the pin net method, (1) a primer is applied to the surface of the existing finishing layer, (2) a resin or cement or a mixture thereof is applied (hereinafter referred to as an underlayer), and (3) the underlayer is not cured before being cured. Attach a net to the surface of the formation, (4) drill holes in the frame through the net (for example, drill holes at the top of each 50 cm square grid), and (5) fix anchor pins in the holes. The net is fixed to the frame with the head of the anchor pin, and (6) resin or cement or their mixture is applied again from above the net (hereinafter referred to as middle layer), (7) tiles, mortar etc. on the surface of the middle layer Fix the finishing layer (hereinafter referred to as surface layer).

Explanatory material for the pin net construction method of the National Building Renovation Cooperative

  According to the pin net method, the base layer and the intermediate layer are integrated by joining through the net of the net, and a state is obtained in which the net is embedded in the middle of the integrated layer. Since the net is fixed to the housing by the anchor pins, the integrated layer is prevented from being separated from the housing. The existing finish layer is accommodated between the integrated layer in which the net is embedded and the housing, and is prevented from falling from the housing.

Although the pin net method is an effective method for preventing the falling accident of the existing finishing layer, it has a problem of difficulty in construction.
(1) In the pin net method, the net is pasted while the underlayer is not cured. In the case where the repair surface is large and the net area and the base layer application range are wide, it is not easy to satisfy the condition.
(2) The conventional pin net method requires a step of forming an intermediate layer after the net is stretched.
(3) The conventional pin net method requires a step of forming a surface layer on the surface of the intermediate layer.
(4) In the conventional pin net method, the intermediate layer and the surface layer are separate, and the net does not participate in the adhesion therebetween. Aging may leave the surface layer separated from the intermediate layer.
In this specification, the building material which can solve the said problem of the conventional pin net construction method is disclosed. The building materials disclosed in the present specification were developed so as to facilitate the construction of the pin net method by sequentially attaching them to the surface of a frame.

The building material disclosed in this specification facilitates the construction of the pin net method by affixing to the surface of the frame in order, and includes a net of a prescribed size and a resin layer attached to the surface side of the net. ing. When the net is brought into close contact with the base layer applied to the surface of the housing, the resin layer is bonded to the base layer through the net of the net and is integrated with the base layer. The undercoat layer and the resin layer are integrated by being bonded through the mesh of the net, and a state in which the net is embedded in the middle of the integrated layer is obtained. Since the net is fixed to the housing by the anchor pins, the integrated layer is prevented from being separated from the housing. The existing finishing layer is contained between the net and the integrated layer in which the net is embedded and the housing, and is prevented from falling out of the housing.
The resin layer referred to herein means a layer of only a resin, a layer of a mixture of resin and cement, or a layer of a mixture to which an appearance improving agent is further added. The resin layer may be attached to the surface of the net and integrated with the base layer applied to the surface of the housing through the mesh of the net.
The resin layer has a substantially rectangular shape (that is, a rectangular shape when a notch formed at each vertex is gradually removed), and a net extends from two adjacent sides of the rectangle. The net extends toward the outside of the resin layer. When four building materials are pasted at positions adjacent to each other in the vertical direction and the horizontal direction, a notch in which the notches formed in each resin layer are continuous is formed. Each building material net extends into its notch (continuous notch).
This building material is stuck on the surface of the frame in order. That is, another building material (following building material) is attached to the position adjacent to the building material (previous building material) stuck on the surface of the frame. When a subsequent building material is pasted at a position adjacent to the preceding building material in the vertical direction, and another subsequent building material is pasted at a position adjacent to the preceding building material in the left-right direction, 4 in the vertical direction and the left-right direction. Sheets of building material will be adjacent to each other, and a notch in which four notches are continuous is formed. In the range of the continuous notch, the relation where four nets of four building materials overlap is obtained. If a relationship in which the four nets adjacent in the vertical direction and the horizontal direction overlap is obtained, it is possible to fix the four nets to the housing at the same time by drilling there and fixing the anchor pin. Since the anchor pin is fixed in the notch range of the resin layer, the resin layer is not damaged.

When the above building materials are used, it is possible to obtain a relationship in which four nets adjacent in the vertical direction and the horizontal direction overlap. If the anchor pin is fixed by drilling a hole at the position, it is possible to prevent the adjacent nets from separating. Also, for each building material, each vertex of the outline of the net is fixed to the frame. A pin net construction method is completed if a building material is put in order and an anchor pin is fixed to a place where four adjacent nets overlap in the vertical and horizontal directions .
According to this building material
(A) Since each building material having a specified size can be attached to the surface of the housing, the problem (1) does not occur even if the repair surface is very large.
(B) The resin layer adhering to the net surface becomes an intermediate layer of the existing pin net method. There is no need to form an intermediate layer at the construction site, and there is no problem (2).
(C) A building material in which the resin layer itself also serves as a surface layer can be manufactured in advance. Therefore, the problems of (3) and (4) described above can be solved.

  The above building materials are attached to the surface of the frame in order. The overlapping net is then perforated in the housing at a position exposed from the resin layer by the notch, and an anchor pin having a head larger than the net of the net is fixed in the hole perforated in the housing. Then, the pin net method is completed.

  In the position where the building material and the building material are adjacent to each other, a portion where notches are continuous is formed. You may implement the process of affixing a decorative board on the notch continuous part. When this process is added, the decorative plate covers the head and the net of the anchor pin to increase the decorative effect.

Instead of the resin layer, a wall panel (substantially flat plate that can be a wall) formed of a material such as a metal plate, a ceramic plate (ceramic tile), a magnetic plate (porcelain tile), or a glass plate may be used. That is, it may be a building material provided with a net of a prescribed size and a wall panel attached to the surface side of the net .
A wall panel uses what adhere | attaches to a foundation layer through the mesh | network of a net | network, when a net | network is stuck to the foundation layer apply | coated to the housing surface. As will be described later, since there are various techniques for increasing the adhesion between the wall panel and the net or the casing, the adhesion between the wall panel and the net does not need to be perfect.
Using the above building materials, if another building material is pasted at a position adjacent to the building material affixed to the housing surface, the net of the building material affixed first and the net of the building material affixed later overlap. that relationship can get, stuck in the order, in turn by fixing the anchor pin, pin net method of construction is completed.

  In order to increase the adhesion between the wall panel and the net or casing, it is preferable to form asperities on the back surface of the wall panel. For example, if a projection penetrating the net of the net is provided on the back surface of the wall panel, when fixing the building material to the housing, a hole for receiving the projection is drilled in the surface of the housing and a chemical anchor or the like is used to make the projection. Can be prevented from coming out of the enclosure. The wall panel can be prevented from separating from the net or the frame.

  Alternatively, if the anchor pin or the head of the member to be fixed to the anchor pin is large, a part of the wall panel may be attached to the housing by fixing the anchor pin or by fixing the member to the anchor pin. It becomes possible to push it. The head can prevent the wall panel from separating from the net or the frame.

When using building materials with wall panels adhering to the surface of the net, a process of pasting subsequent building materials on the surface of the frame adjacent to the preceding building material previously pasted on the surface of the frame, and multiple adjacent sheets A step of drilling in the frame at the position of the notch formed at the boundary of the building material, and the holes drilled in the frame are larger than the net mesh of the preceding building material and the net of the subsequent building material The pin net construction method is completed by repeating a cycle having an anchor pin fixing step of fixing an anchor pin having a head having a size covering at least a part of each of the wall panels.
The anchor pin referred to here may be the anchor pin itself or may be a whole in which a member other than the anchor pin main body is fixed to the anchor pin main body. That is, the head may be the head of the anchor pin itself or the head of a member fixed to the anchor pin body.
The technology to prevent not only the net but also the surface layer from being separated from the housing by the head of the anchor pin is particularly effective when using building materials with wall panels attached to the net surface. The present invention can also be applied to a building material to which a resin layer adheres, and it is more effectively prevented that the resin layer separates from the net or the casing.

Whether it is a building material with a resin layer attached to the net surface or a building material with a wall panel attached to the net surface, the pin net method can be completed by repeating the unit cycle. It is simplified. In this method, first, one net is developed at the repair start position on the surface of the housing. After that, the following unit cycle is repeated.
The unit cycle consists of (1) expanding a specified size of a succeeding net at a position where a part overlaps the preceding net and the remaining part extends to a position adjacent to the preceding net, and (2) the preceding net and the succeeding net are It is composed of three steps: drilling into the housing in the overlapping position, and (3) fixing an anchor pin having a head larger than the mesh of the preceding net and the following net in the hole drilled in the housing. When the unit cycle is repeated, the preceding net becomes the expanded net in the preceding unit cycle, and the following net becomes the expanded net in the cycle. That is, in each unit cycle, (1) a new net of a specified size is developed at a position where a part overlaps the net developed in the preceding cycle and the remaining part extends to a position adjacent to the net. The net developed in the cycle and the new net are perforated in the case where the new net overlaps. (3) The hole perforated in the case has a larger head than the net developed in the previous cycle and the net of the new net. It will fix the anchor pin.
The above method is particularly effective when using building materials in which a layer that serves both as an intermediate layer and a surface layer is attached to the surface of the net. To facilitate the construction. When using only the net, (1) apply a base layer on the surface of the frame of the specified size, (2) spread the net of the specified size on the surface of the base layer, and (3) intermediate the net surface of the specified size Repeat the unit cycle to form a layer. The pin net method is completed by repeating the unit cycle in the positional relationship in which the trailing net is developed at the position adjacent to the leading net. The surface layer may be completed for each specified size, or the repair surface may be processed in a lump. Alternatively, an intermediate layer that also serves as a surface layer may be used.
Although this pin net method is particularly effective for the prevention of exfoliation of the existing finish layer, it can be applied to a newly built frame. It is possible to prevent the wall material from peeling from the housing.
When the intermediate layer and the surface layer are firmly bonded to the net, or when the intermediate layer serving also as the surface layer is firmly attached to the net, the base layer can be omitted. Since each vertex of the net of the prescribed size is fixed to the housing, the intermediate layer and the surface layer or the intermediate layer that serves as the surface layer does not fall from the housing. It is also possible to prevent the existing finish layer from falling by nets of a prescribed size. In the case of developing the net, the case of developing the net on the base layer and the case of developing the net on the surface of the housing where the base layer is not applied are included.

  Details and further improvements of the technology disclosed in this specification will be described in the following “DETAILED DESCRIPTION”.

  When the above building materials are used, the work for the pin net method is simplified, the construction period is shortened, and the construction cost is reduced. Furthermore, the durability after the construction of the pin net method is also improved. This pin net construction method can also be applied to new structures.

(Example)
FIG. 1 shows a plan view of a building material 2 of the embodiment. The building material 2 includes a resin layer 4 and a net 6 attached to the back surface of the resin layer 4. It may be said that the resin layer 4 is attached to the surface of the net 6. A net 6 is laid along the bottom of the mold, and the uncured resin is poured into the mold, and the resin is cured in the mold to produce a building material in which the resin layer 4 adheres to the surface of the net 6. can do. The resin layer 4 is a substantially square having a side of about 50 cm, and notches 4a, 4b, 4c, and 4d are formed at four corners. One side of each notch is about 2.5 cm. The net 6 extends outward from the left side of the resin layer 4 and the width L of the extending portion 6e is about 5 cm. The net 6 also extends outward from the lower side of the resin layer 4, and the width L of the extending portion 6f is about 5 cm. A net 6a extends also to the notch 4a. The portion 6a extending at the position of the notch 4a is a square having a side of about 5 cm. A net 6b extends also to the notch 4b. The portion 6b extending at the position of the notch 4b is a square having a side of about 5 cm. The part 6b and the part 6e partially overlap. On the left side of the part 6b, the net 6 is notched. The notch 6j has a side of 2.5 cm. Since the notches 6j are formed, when the building materials 2 are pasted in order, the net 6 covers the surface of the resin layer 4 that has been pasted in portions other than the notches of the resin layer 4. I have not. A net 6c also extends through the notch 4c. The portion 6c extending at the position of the notch 4c is a square having a side of about 5 cm. The portion 6c, the portion 6e and the portion 6f partially overlap. A net 6d also extends through the notch 4d. A portion 6d extending at the position of the notch 4d is a square having a side of about 5 cm. The part 6d and the part 6f partially overlap. The portion 6a extends to a notch 4a formed at the apex at a position not in contact with the left side and the lower side of the resin layer 4 from which the nets 6e and 6f extend.

  FIG. 8 shows a cross-sectional view of the building material 2. The resin layer 4 is attached to the surface of the net 6. After the construction, the base layer 60 and the resin layer 4 are integrated through the mesh of the net 6. The net 6 is embedded in the middle of the integrated layer of the base layer 60 and the resin layer 4, and the base layer 60 prevents the resin layer 4 from being peeled from the net 6. When the net 6 is fixed to the casing 50 by anchor pins described later, the resin layer 4 is also fixed to the casing 50.

As shown in FIG. 6, in the case of the present embodiment, the tile 54 is attached to the surface of the casing 50 via the mortar layer 52. Although the case where the existing finishing layer is the tile 54 is illustrated, the existing finishing layer is not limited to the tile. Reference numeral 56 is joint cement.
When repairing the housing surface, as shown in FIG. 7, a primer is applied to the surface of the existing finish layer 54, and a resin, cement, or a mixture thereof (becomes an adhesive) is applied to the surface of the primer film. Hereinafter, the layer serving as the adhesive is referred to as a base layer 60. The foundation layer 60 may be applied for each size of the building material 2, or may be applied at one time to the surface of the casing corresponding to a plurality of building materials. However, the area of the base layer 60 to be applied at one time is determined according to the number of building materials that can be attached before the applied base layer 60 is cured.
After applying the base layer 60, the building material 2 is attached. This operation is performed before the underlayer 60 is cured. When the net 6 is brought into close contact with the surface of the base layer 60 before curing, the base layer 60 and the resin layer 4 are bonded and integrated through the mesh of the net 6. For the underlayer 60, it is preferable to use a resin material that is fused and matched with the resin layer 4. As a result, as shown in FIG. 8, the base layer 60 and the resin layer 4 are integrated through the net of the net. The foundation layer 60 and the resin layer 4 are integrated by being bonded through the mesh of the net 6, and a state in which the net 6 is embedded in the middle of the integrated layer is obtained.

  FIG. 1 shows a state in which the first piece of building material 2 is pasted on the surface of the housing. FIG. 2 shows a state where the second building material 22 is pasted to the left. At the time of construction, the next building material 22 is stuck to the adjacent position on the side where the net extends from the building material 2 stuck earlier. For this reason, the net 6 e extending from the first building material 2 is covered with the second building material 22. At the position along the right side of the second building material 22, the two nets overlap. In the present embodiment, the fact that the number at the end is 2 means that it is a building material, and it is indicated that the numbers of ten digits are the second, third and fourth sheets.

  FIG. 3 shows a state where a third building material 32 is pasted next to the first building material 2. At the time of actual construction, the next building material will be put on the left side of the building material put earlier, and it will be put on the line under it after the line is finished. 1 to 4 show notches at positions where four building materials are adjacent (the notch 4c of the first building material 2, the notch 24d of the second building material 22, and the notch of the third building material 32. 34b shows a process in which the four nets 6 overlap at a position where the notch 44a of the fourth building material 42 is continuous, and illustration of the building material continuous on the left side is omitted. As shown in FIG. 3, the net 6 f extending from the first building material 2 is covered with the third building material 32 by pasting the third building material 32. At a position along the upper side of the third building material 32, the two nets overlap.

  FIG. 4 shows a state where the fourth building material 42 is pasted below the second building material 22 and to the left of the third building material 32. By attaching the fourth building material 42, the net 26 f extending from the second building material 22 is covered with the fourth building material 42. At the position along the upper side of the fourth building material 42, the two nets overlap. Moreover, the net | network 36e extended from the 3rd building material 32 is covered with the 4th building material 42 by sticking the 4th building material 42. FIG. At the position along the right side of the fourth building material 42, the two nets overlap. In addition, when the fourth building material 42 is pasted, at the position where the four building materials are adjacent, four notches (the notch 4c of the first building material 2 and the notch 24d of the second building material 22; The notch 34b of the third building material 32 and the notch 44a) of the fourth building material 42 are continuous, and a square notch 5 appears. In the square cutout 5, there are four nets 6 (the net 6 c of the first building material 2, the net 26 d of the second building material 22, the net 36 b of the third building material 32, and the fourth building material. The 42 nets 46a) will be duplicated.

  FIG. 5 shows four notches (the notch 4c of the first building material 2, the notch 24d of the second building material 22, the notch 34b of the third building material 32, and the fourth building material 42. In the square-shaped notch 5 that appears by the continuous notch 44a), four nets 6 (the net 6c of the first building material 2, the net 26d of the second building material 22, and the third sheet) The relationship in which the net 36b of the building material 32 and the net 46a) of the fourth building material 42 overlap is shown more clearly. Moreover, by sticking the 4th building material, it is confirmed that a net | network is not exposed on the surface side of the resin layer in parts other than the said square-shaped notch 5. FIG. In particular, as shown in FIG. 5 (3), a notch 36j is formed in the net 36 of the third building material 32, and as shown in FIG. 5 (4), the net of the fourth building material 42 is formed. The shape of the net 46a extending at the notches 46a of 46 corresponds to the square-shaped notches 5 which appear as four notches continue. Therefore, it is confirmed that the four nets 6 overlap inside the square notch 5 and the net 6 is not exposed on the surface side of the resin layer 4 in a portion other than the notch 5.

  FIG. 8 and subsequent figures show cross-sectional views after four building materials have been pasted. Along the line segment from the first building material 2 to the third building material 32 through the square notch 5 formed by the continuous four notches 4c, 24d, 34b, 44a. The cross section is shown.

  Once the building material is attached to the surface of the frame, the net 6 is fixed to the surface of the frame using anchor pins described later. In the present embodiment, the anchor pin is fixed to the housing 50 at the position of the square notch 5 which appears as the four notches 4c, 24d, 34b, 44a are continuous. That is, four nets 6 (the net 6c of the first building material 2, the net 26d of the second building material 22, the net 36b of the third building material 32, and the net 46a of the fourth building material 42). The anchor pin is fixed to the housing 50 at the overlapping position.

FIG. 9 shows a state in which the casing 50 is pierced through the overlapping four nets. Holes 62 are formed.
FIG. 10 shows the anchor pin 64 inserted into the hole 62. As shown in FIG. The anchor pin 64 has a head 65 larger than the mesh of the net 6, and the nets 6 c, 26 d, 36 b, 46 a overlapping the head 65 are pressed against the housing 50 side. In FIG. 10 and thereafter, a state is shown in which four nets 6c, 26d, 36b and 46a in the notched portion are in close contact with each other to form one sheet.

FIG. 11 shows how the core rod 70 is driven into the anchor pin 64. A through hole 66 is formed along the axial center of the anchor pin 64. The wall surface of the through-hole 66 is inclined at the tip of the anchor pin (see reference numeral 68), and the diameter of the through-hole is narrowed toward the tip of the anchor pin. When the core rod 70 is driven there, the diameter of the tip of the anchor pin 64 is expanded as shown in FIG. Therefore, the enlarged side wall 72 in the vicinity of the tip of the anchor pin 54 bites into the concrete housing 50, and the anchor pin 64 is firmly fixed to the housing 50. If necessary, an adhesive may be injected from the through hole prior to driving in the core rod 70.
FIG. 13 shows a state in which the decorative plate 74 is pasted at the position of the square-shaped notch 5 that appears when the four notches 4c, 24d, 34b, and 44a are continuous. When the decorative plate 74 is pasted, the net 6 and the anchor pin 64 are covered and the appearance is improved. Further, the decorative plate 74 becomes a point to improve the design of the surface of the casing.

  In the pin net method, it is recommended to fix the anchor pin at each vertex position of a square lattice having a side of 50 cm. In addition, it is recommended to provide a 5 cm overlap at the seam between nets. If the building material 2 of an Example is used, said conditions can be satisfy | filled.

  In the building material 2 of this embodiment, the resin layer 4 serves as both the intermediate layer and the surface layer. Therefore, the building material 2 is attached, the anchor pin is fixed, and if necessary, the decorative plate 74 is attached to complete the pin net method. Compared with the conventional pin net method, the number of necessary steps can be significantly reduced.

In the present embodiment, the anchor pin 64 is fixed at the position of the square notch 5 which appears as four notches continue. Furthermore, the anchor pin may be fixed through the resin layer 4 at a position along the upper side of the fourth building material 42 and / or a position along the right side.
In the case of using an anchor pin having high decorativeness and durability, the head of the anchor pin may be exposed on the surface of the resin layer 4. In that case, the four corners of the resin layer 4 may not have the notches. If the nets 6e and 6f are used to overlap and the anchor pins are fixed over the resin layer 4 at the position where the adjacent nets overlap, the pin net method is completed.

Second Embodiment
Instead of the resin layer 4, a wall panel formed of a material such as a metal plate, a ceramic plate (ceramic tile), a porcelain plate (porcelain tile), or a glass plate may be used. The material of the wall panel is not particularly limited as long as it can be used for the wall.
When a wall panel is used, the wall panel 82 is attached to the surface of the net 6 using an adhesive 80 as shown in FIG. As will be described later with reference to FIG. 19, since the adhesive 80 is integrated with the base layer 60 through the mesh of the net 6, the net 6 and the wall panel 82 are firmly attached.

In order to enhance the adhesion of the wall panel 82 to the housing, as shown in FIG. 15, columnar protrusions 82 a may be formed on the back surface of the wall panel 82. When the building material is attached to the case, the hole for receiving the protrusion 82a is bored in the case and the columnar protrusion 82a is fixed thereto by the chemical anchor technique, so that the wall panel 82 can be prevented from coming off the case.
As shown in FIG. 16, a recess 82 b may be formed on the back surface of the wall panel 82. It is preferable that the cross section of the recess 82b is narrow on the back side and enlarged on the front side. When the net 6 enters the recess 82b and is fixed by the adhesive 80, the adhesion amount of the net 6 and the wall panel 82 is increased.

FIG. 17 shows a notch 92 that appears at the boundary between the four wall panels 82, 84, 86, 88, and an anchor pin head 94 embedded in the notch 92. FIG. 18 shows a state in which the decoration / peeling prevention plate 96 is fixed to the head 94 of the anchor pin. The decoration / peel prevention plate 96 covers a part of the adjacent four wall panels 82, 84, 86, 88 and presses it to the housing side. The decoration / peel prevention plate 96 decorates the periphery of the notch 92 and prevents the four wall panels 82, 84, 86, 88 from peeling from the casing.
FIG. 19 shows a cross section of FIG. The points other than the head 94 of the anchor pin and the decoration / peeling prevention plate 96 are the same as those in FIG.
As shown in FIG. 19, the outer periphery of the head 94 of the anchor pin used in this embodiment is threaded. On the back surface of the decoration / peeling prevention plate 96, a screw that engages with the screw of the head 94 is cut, and the decoration / peeling prevention plate 96 is fixed to the anchor pin 64 by engaging both of them. Since the decoration / peeling prevention plate 96 fixed to the anchor pin 64 presses the vicinity of the apexes of the four wall panels 82, 84, 86, 88 toward the housing, the wall panels 82, 84, 86, 88 peel from the housing. There is nothing to do. The decoration / peeling prevention plate 96 is fixed to the anchor pin 64, and the whole can be called an anchor pin. The anchor pin body 64 and the decoration / peeling prevention plate 96 constitute an anchor pin.
