Description

  This specification discloses the building material developed for the pin net method, and the 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 this specification, what has a possibility of peeling and falling is called an existing finishing layer.
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 an existing finish layer, (2) a resin or cement or a mixture thereof is applied (hereinafter referred to as an underlayer), and (3) the base layer is not cured before it is cured. A net is stretched over the surface of the formation, and (4) a frame is drilled through the net (for example, a hole is drilled at each vertex of a square grid with a side of 50 cm). (5) An anchor pin is fixed to the hole. Fix the net to the housing with the head of the anchor pin, (6) Reapply resin or cement or their mixture from the net (hereinafter referred to as the intermediate layer), (7) Tile or mortar etc. on the surface of the intermediate layer A finishing layer (hereinafter referred to as a surface layer) is fixed.

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 pin, the integrated layer is prevented from being detached 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.

The pin net method is an effective method for preventing an accidental fall of an existing finished layer, but has a problem that it is difficult to construct.
(1) In the pin net method, the net is pasted while the underlayer is not cured. If the repair surface is large and the net area and the undercoat layer application range are wide, it is not easy to satisfy the conditions.
(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 is not involved in the adhesion between them. There is still a possibility that the surface layer peels from the intermediate layer due to aging.
In this specification, the building material which can solve the said problem of the conventional pin net construction method is disclosed. The building material disclosed in this specification has been developed to facilitate the construction of the pin net method by sticking to the surface of the frame in order.

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 base layer and the resin layer are integrated by joining through the net of the net, and the net is embedded in the middle of the integrated layer. Since the net is fixed to the housing by the anchor pin, the integrated layer is prevented from being detached 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.
The resin layer here refers to a resin-only layer, a resin-cement mixture layer, or a mixture layer to which an appearance improving agent is further added. The resin layer may be any material that adheres to the surface of the net and is integrated with the base layer applied to the housing surface via the net of the net.
The resin layer is substantially polygonal, and a notch is formed at each vertex. The term “substantially polygonal” as used herein refers to a polygon when notches are excluded.
The net extends at least to the notch. Here, “at least” means that it is not excluded that the net extends from the resin layer even in a portion other than the notch.
This building material is stuck on the surface of the frame in order. That is, another building material (following building material) is pasted to a position adjacent to the building material (previous building material) stuck on the surface of the frame. At this time, in the notch portion, the net of the building material previously pasted and the net of the building material pasted later overlap, and the relationship that is not covered with the resin layer of the building material pasted later is obtained. It is done.

When the above building materials are used, adjacent nets overlap at the notch formed at each vertex position of the polygonal resin layer. If the anchor pin is fixed by drilling in the housing at that position, the adjacent nets can be prevented from separating. Moreover, each vertex of the outline of a net is fixed to a housing for every building material. If the building materials are pasted in order and the anchor pins are fixed at the place where the adjacent notches of the building materials continue, the pin net construction method is completed.
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 above problems (3) and (4) can be solved.

The resin layer may be triangular, hexagonal, or the like, but is preferably in the form of a substantially rectangular shape or a substantially square shape with notches formed at the four corners. In that case, it is preferable that the net extends from two adjacent sides of the resin layer, and the net also extends to a notch formed at a vertex at a position not in contact with the two sides.
According to the above, when building materials are pasted on the surface of the frame in order, a new building material is pasted on the side where the net extends from the previously pasted building material, so that it is pasted first on the part other than the notch. The attached building material net is covered with a resin layer of the building material attached later. On the other hand, the four nets extending from the four adjacent building materials overlap with each other in the notch formed at the apex at a position not in contact with the two sides where the net extends. Four nets can be fixed to the housing with one anchor pin.

  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 construction 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 head of the anchor pin and the net are covered with the decorative plate, and the decorative effect is increased.

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. In this case, the wall panel is substantially polygonal, and a building material having a requirement that a notch is formed at each vertex and a net extends at least in the notch is used.
As the wall panel, when the net is brought into close contact with the base layer applied to the surface of the housing, the wall panel is bonded to the base layer through the net of the net. 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, when another building material was pasted at a position adjacent to the building material pasted on the surface of the housing, the notched portion was pasted on the building material net pasted later. The building material net overlaps and a relationship that is not covered by the building material wall panel pasted later can be obtained, and the pin net construction method is completed by pasting in order and fixing the anchor pins in order.

  In order to increase the adhesion between the wall panel and the net or housing, it is preferable to form irregularities 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 head of the anchor pin or the member to be fixed to the anchor pin is large, by fixing the anchor pin, or by fixing the member to the anchor pin, a part of the wall panel is made into a housing by the head. It becomes possible to press. 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 different from 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. It can also be applied to building materials to which a resin layer is attached, and more effectively prevent the resin layer from separating 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. Simplified. In this method, first, one net is developed at the repair start position on the surface of the housing. Thereafter, the following unit cycle is repeatedly executed.
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 a net developed in the preceding unit cycle, and the succeeding net becomes a net developed 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. Anchor pin will be fixed.
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. Facilitates 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 the layer. The pin net method is completed by repeating the unit cycle in a positional relationship in which the succeeding net is developed at a position adjacent to the preceding 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.
This pin net method is particularly effective in preventing peeling of existing finish layers, but it can also be applied to newly built frames. 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 the net group of the prescribed size. The case of developing a net includes a case where a net is developed on a base layer and a case where a net is developed on a housing surface on which the base layer is not applied.

  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 extending portion 6e has a width L of about 5 cm. The net 6 also extends outward from the lower side of the resin layer 4, and the extending portion 6f has a width L of 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 portion 6b, the net 6 is cut away. 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. There is nothing. 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 part 6c, the part 6e, and the part 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 with an anchor pin 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, a tile 54 is pasted on the surface of the casing 50 via a 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 a 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 once to the housing surface having an area corresponding to a plurality of building materials. However, the area of the base layer 60 applied at a time is determined in accordance with the number of building materials that can be pasted before the applied base layer 60 is cured.
After the foundation layer 60 is applied, 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 base layer 60 and the resin layer 4 are integrated by joining through the mesh of the net 6, and the net 6 is embedded in the middle of the integrated layer.

  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 number at the end of 2 means that it is a building material, and the numbers of 10 digits indicate the second sheet, the third sheet, and the fourth sheet.

  FIG. 3 shows a state in which a third building material 32 is pasted below the first building material 2. At the time of actual construction, the next building material is pasted on the left side of the building material that has been pasted, and after the row is finished, it is pasted on the lower row. 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 and the position where the notches 44a of the fourth building material 42 are continuous), the process of overlapping the four nets 6 is shown, and the 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 the position along the upper side of the third building material 32, the two nets overlap.

  FIG. 4 shows a state in which the fourth building material 42 is pasted on the position below the second building material 22 and on the left side 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. 42 nets 46a) overlap.

  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. Further, it is confirmed that the net is not exposed on the surface side of the resin layer in the portion other than the square notch 5 by pasting the fourth building material. 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 through the 46 notches 44a corresponds to the square-shaped notch 5 that appears when the four notches are continuous. 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. A cross section is shown.

  After the building material is pasted on 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 that appears when the four notches 4c, 24d, 34b, and 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 perforated through four overlapping nets. A hole 62 is formed.
FIG. 10 shows a state where the anchor pin 64 is inserted into the hole 62. 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 subsequent figures, a state in which the four nets 6c, 26d, 36b, and 46a in the notch are in close contact with each other is illustrated.

FIG. 11 shows how the core rod 70 is driven into the anchor pin 64. A through hole 66 is formed along the axis 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 portion of the anchor pin 64 increases 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 before the core rod 70 is driven.
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 serves as a point, and the design of the housing surface is improved.

  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 pin net construction method is completed by attaching the building material 2, fixing the anchor pins, and attaching the decorative plate 74 if necessary. 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 that appears when the four notches are continuous. Furthermore, the anchor pin may be fixed over 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.
When using an anchor pin with high decorativeness and durability, the head of the anchor pin may be exposed on the surface of the resin layer 4. In that case, it is not necessary to provide notches at the four corners of the resin layer 4. 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 the 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 reinforce the adhesion of the wall panel 82 to the housing, columnar protrusions 82a may be formed on the back surface of the wall panel 82 as shown in FIG. When the building material is affixed to the housing, a hole for receiving the protrusion 82a is drilled in the housing, and the columnar protrusion 82a is fixed thereto by a chemical anchor technique, whereby the wall panel 82 can be prevented from peeling off from the housing.
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 with the adhesive 80, the adhesion amount between the net 6 and the wall panel 82 increases.

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 / peeling prevention plate 96 covers a part of the four adjacent wall panels 82, 84, 86, and 88 and presses it against the housing side. The decoration / peeling prevention plate 96 decorates the periphery of the notch 92 and prevents the four wall panels 82, 84, 86, 88 from being peeled from the housing.
FIG. 19 shows a cross section of FIG. The points other than the anchor pin head 94 and the decoration / peeling prevention plate 96 are the same as 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.
