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 conventional pin net method, the net must be pasted while the underlayer is not cured. If the repair surface is vast, 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 includes a net and a resin layer. 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 covers both the front and back surfaces of the net, and the front side resin layer and the back side resin layer are bonded through the net of the net. That is, the net is embedded at an intermediate depth of the resin layer in which the front surface side resin layer and the back surface side resin layer are integrated.

As illustrated in FIG. 1, the resin layer has a rectangular or square shape with notches (4a, 4b, 4c, 4d) formed at four corners. The net (6) extends outward from two adjacent sides of the resin layer (4), and the extending portions (6e, 6f) have a width of 5 cm or more. The notch (4a) formed at the apex at the position not in contact with the two sides where the net (6e, 6f) extends from the resin layer (4) spans a range in which the notch of the adjacent building material continues. The net (6a) extends. In the notch (4b) adjacent to the notch (4a), the net is cut in a range that does not belong to either the range (6b) where the notch of the adjacent building material continues or the net (6e) extending from the side. (6j).

According to the above building materials , when the building materials are pasted in order on the surface of the frame, the following results can be obtained by pasting new building materials on the side where the net extends from the building material pasted first. it can.
In the notch part,
The building material net affixed first and the building material net affixed later overlap,
It is not covered with the resin layer of the building material pasted later.
In parts other than the notch,
The building material net affixed first is covered with the resin layer of the building material affixed later,
The net of the building material pasted later does not cover the surface of the resin layer of the building material pasted first.
In the range where the notches of four adjacent building materials continue, four nets overlap. Four nets can be fixed to the housing with one anchor pin. Moreover, the net | network of the building material affixed later is not exposed to the surface of the resin layer of the building material affixed previously.

  The above building materials are attached to the surface of the frame in order. Then, at the position where the overlapping net is exposed from the resin layer by the notch, the casing is punched, and the anchor pin having a head larger than the net of the net is fixed to the hole drilled in the casing. 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 the notch is 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.

  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 number of steps required for the pin net method is reduced.

The resin layer 4 includes a back surface side resin layer 4g and a front surface side resin layer 4h, and a net 6 is embedded between the both. The back surface side resin layer 4 g and the front surface side resin layer 4 h are bonded through the mesh of the net 6. The resin layer 4 and the net 6 are firmly integrated. When the net 6 is fixed to the housing 50 with an anchor pin described later, the resin layer 4 is also fixed to the housing 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, the primer 60 is applied to the surface of the existing finish layer 54 as shown in FIG. Thereafter, as shown in FIG. 8, the building material 2 is pasted by applying an adhesive to the back surface of the building material 2. For the adhesive, the same resin as the back side resin layer 4g is used. In order to stick using the same resin, the back side resin layer 4g and the adhesive are fused, and the back side resin layer 4g is firmly fixed to the primer layer 60.

  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 a position where the notches 44a of the fourth building material 42 are continuous), the four nets 6 overlap each other, and the illustration of the building material continuous on the left side is omitted. By attaching the third building material 32, the net 6 f extending from the first building material 2 is covered with 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 a square notch 5 formed by 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 this 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.

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 a 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 the present embodiment, the surface side resin layer 4h also serves as a finishing 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.
