Description

The present invention relates to a tiled outer wall by tiling method of Method及Biko to the outer wall tiled walls.

  If the outer wall is finished with a mortar spray finish or siding material, the surface may deteriorate over time and the aesthetics may be impaired. For example, the sprayed mortar layer may be partially lifted or the coating on the siding surface may be partially peeled off.

  In such a case, the deteriorated existing siding material may be removed and a new siding material may be attached. However, this is a large-scale construction and a large amount of dust is generated during the removal operation.

  As a method of tiling an outer wall without removing a deteriorated portion, there is a method of attaching a trunk edge to the outer wall and fastening a tile panel thereon.

  In the tiled construction method using the trunk edge and the tile panel, the finished thickness is considerably increased due to the trunk edge and the substrate of the tile panel. Further, it is not suitable for partially tiled tiles. Moreover, since the trunk edge and the tile panel are rigidly fixed to the outer wall, the movement (extension / contraction) of the outer wall directly affects the tile, and the tile may crack.

  As another construction method, Japanese Patent Laid-Open No. 2000-213181 describes a construction method in which a net is fixed with a washer and a screw, and a tile is pasted with a pasting material such as cement-based mortar.

  1-4 of the same publication, after attaching a net to the outer wall via an adhesive for attaching the net, a recess for accommodating a washer and a screw head on the outer wall with a drill or the like. Form a place. Next, the net is fastened to the outer wall by screwing into the recess through a washer. After that, an adhesive for tiling is applied from above the net, and then tiled.

  In this outer wall tiling method, the washer and the screw head are disposed in a recess provided in the outer wall, and therefore do not protrude from the front surface of the net. For this reason, the application | coating thickness of an adhesive agent can be made small.

  7 to 9 of the same publication, the washer is fixed to the dish-shaped head by welding, and the head is not protruding from the surface opposite to the washer net. The net is fastened to the outer wall with the screws.

In this outer wall tiling method, since the screw head does not protrude from the surface opposite to the washer net, the protruding thickness from the net after screwing is sufficiently small. Moreover, it is not necessary to provide a recess for accommodating the washer and the screw head on the outer wall, and the construction work is easy.
JP 2000-2131181 A

  In FIGS. 1-4 of the said Unexamined-Japanese-Patent No. 2000-213181, since it is necessary to provide the recess for accommodating a washer and a screw head in an outer wall, construction work takes time.

  In the outer wall tiling method shown in FIGS. 7 to 9 of the publication, since the washer is fixedly integrated with the head of the screw, for example, when the screw is obliquely screwed into the outer wall, the washer Cannot completely overlap the outer wall, only a part of the outer peripheral edge abuts the net, and the opposite side is lifted.

  For this reason, in this case, the washer does not sufficiently contact the net, and the net cannot be pressed firmly. Further, it becomes easy to catch the adhesive application iron on the raised portion of the washer, and the workability is lowered.

The invention, together with a easy installation work, and to provide a tiled outer wall by method tiled method及Biko outer wall that can be put fastened firmly the outer wall of the net.

The tiling method of the outer wall of the present invention (Claim 1) is a method of tiling the outer wall,
The net is overlapped on the outer wall, the countersunk screw is screwed into the outer wall through a washer having a screw insertion hole, the net is fastened to the outer wall, and an adhesive is applied to the outer wall from the top of the net. In the tiled construction method of the outer wall to be stretched, the washer has a disk shape, and the screw insertion hole of the washer has a tapered shape into which the head of the countersunk screw is fitted. a tiled method of bis beating to that outer wall such that the non-protruded from the net on the opposite side of the surface of the washer, posts or studs are disposed an adhesive tape whose both surfaces made of adhesive material on the rear side of the outer wall And the side end of the first net is overlaid on the adhesive tape, and the side end of the second net disposed adjacent to the first net is overlaid thereon, These first and second nets Is attached to the outer wall by the adhesive tape, it is characterized in that the attaching fastening the net to the outer wall by screwing a countersunk screw to the external wall through the washer to reach the pillar or stud.

  In the present invention, when a plurality of exterior materials are disposed on the outer wall, it is preferable to attach the tape across the joint between adjacent exterior materials prior to overlapping the net on the outer wall. .

  As this tape, for example, a single-sided adhesive tape referred to as “joint tape” or the like obtained by adhering or impregnating an adhesive material on one surface of a strip-shaped nonwoven fabric is preferable.

The outer wall of the present invention (Claim 2 ) is obtained by tiling the outer wall by the method of the present invention .

  In the tiling method for the outer wall of the present invention (Claim 1), the screw insertion hole of the washer has a tapered shape into which the head of the countersunk screw is fitted, and the head of the countersunk screw is of the washer. It is non-protruding from the surface opposite to the net (hereinafter sometimes referred to as the outward surface). For this reason, when the net is fastened to the outer wall with the washer and the countersunk screw, the head of the countersunk screw does not protrude from the outward surface of the washer, and the protruding thickness from the outer surface of the net is sufficiently small. Thereby, it is not necessary to provide the recess for accommodating a washer and a screw head in an outer wall, and construction work is easy.

  Also, in this outer wall tiling method, the washer is not fixed and integrated with the head of the screw, so even if the screw is driven obliquely with respect to the outer wall, the washer is almost parallel to the outer wall, The net can be firmly fastened to the outer wall by the washer. Further, since the washer is substantially parallel to the outer wall, the iron is not caught on the washer when the adhesive is applied, and the adhesive application work can be performed smoothly.

  In the present invention, when a plurality of exterior materials are disposed on the outer wall, the tape may be attached across the joint between adjacent exterior materials before the net is stacked on the outer wall. preferable. In this case, even if each exterior material expands and contracts due to a temperature change or the like and the adjacent exterior materials are displaced from each other, the stress applied to the tile due to this displacement is absorbed by the tape. Cracking, peeling and the like can be prevented.

  As this tape, a tape called “joint tape” or the like obtained by adhering or impregnating an adhesive material on one surface of a belt-like nonwoven fabric has high stress absorption performance and is preferable.

In the present invention, a pressure-sensitive adhesive tape made of a pressure-sensitive adhesive material on both sides is attached to the outer wall, the side ends of the first net are overlapped on the pressure-sensitive adhesive tape, and the first net is disposed adjacent to the first net. The side ends of the second net are overlapped, and the first and second nets are attached to the outer wall with the adhesive tape . For this reason , when arranging a plurality of nets on the outer wall, each net can be temporarily fastened to the outer wall sequentially via the adhesive tape, so that the workability is extremely high. At this time, the side edges of adjacent nets are attached to a common adhesive tape, so the amount of tape used can be reduced and the number of steps of attaching the adhesive tape to the outer wall can be reduced. It can be carried out.

When the net is attached to the outer wall with the adhesive tape in this way, the tucker may be driven into the outer wall through the side edge of the net and the adhesive tape. By doing so, the side edge of the net can be securely fastened to the outer wall .

FIG. 4 is a cross-sectional view taken along line B-B in FIG. 4A, FIG. 4 is a vertical cross-sectional view of the outer wall tiled by this tiling method, and FIG. 5 is a cross-sectional view taken along line V-V in FIG.

In this reference example , the outer wall 1 is composed of a plurality of plate-like exterior materials 4 attached to a pillar 2 and a stud 3. However, the outer wall may be any of various types such as a concrete wall, a siding wall, a mortar spray wall, or an existing outer wall.

  As shown to Fig.1 (a), the joint tape 5 is affixed ranging over the joint line of adjacent exterior materials 4 and 4. In this embodiment, the joint tape 5 is a single-sided adhesive tape in which butyl rubber is attached or impregnated as an adhesive material on one surface of a strip-shaped nonwoven fabric, and is elastic (cushioning) in both the thickness direction and the surface direction. have. In this embodiment, as shown in FIG. 1A, the exterior materials 4 are arranged in multiple rows in the left-right direction and in multiple stages in the up-down direction, and the joint tape 5 is an exterior material adjacent in the left-right direction. Although it is provided only along the joint between the four and four, it may be provided along the joint between the upper and lower exterior members 4 and 4.

  Next, a double-sided adhesive tape (not shown) is attached to the front surface of the outer wall 1. This double-sided pressure-sensitive adhesive tape is obtained by adhering or impregnating butyl rubber as an adhesive material on both sides of a belt-like nonwoven fabric. Thereafter, as shown in FIG. 1B, a synthetic fiber net 6 is placed on the outer wall and attached to the double-sided adhesive tape. Next, the net 6 is fixed to the outer wall 1 with washers 7 and countersunk screws 8 (8A, 8B).

  In addition, as shown in FIG. 5, in the location where the pillar 2 or the intermediary pillar 3 is arrange | positioned on the back side of the exterior material 4, this exterior material 4 and its back side (between the exterior material 4 and the pillar 2 or the intermediary pillar 3) The plate screw 8A, which is longer than the sum of the thickness with the body edge 9 provided on the platen, is used in a place where the column 2 and the inter-column 3 are not arranged, and a plate having a length substantially the same as the thickness of the exterior material 4. Screw 8B is used. The long countersunk screw 8 </ b> A passes through the exterior material 4 and the trunk edge 9 and is screwed up to the pillar 2 or the intermediate pillar 3. The short countersunk screw 8 </ b> B hardly or not protrudes from the back surface of the exterior material 4.

  The net 6 is fixed to the pillars 2 and the intermediate pillars 3 through long screws 8A and washers 7.

  The opening of the net 6 is preferably about 5 to 20 mm.

  The washer 7 has a substantially disk shape having a diameter larger than the opening of the net 6. A screw insertion hole 7 a is provided at the center of the washer 7. As shown in FIG. 5B, the screw insertion hole 7a has a taper shape into which substantially the entire head 8a of the countersunk screw 8 is fitted. For this reason, after screwing, as shown in FIG. 4, the head 8 a is non-projecting from the outward surface (surface opposite to the net 6) of the washer 7.

  Next, as shown in FIG. 2, an elastic adhesive 10 for tile bonding is applied so that the net 6 can be applied. As the elastic adhesive 10, a modified epoxy-based or modified silicon-based adhesive or the like can be used.

  Thereafter, the tile 11 is pressed and bonded onto the elastic adhesive layer. Then, fill the joints as necessary.

  The tiled outer wall is a beautiful tile wall.

  In this outer wall tiling method, the screw insertion hole 7 a of the washer 7 has a tapered shape in which the head 8 a of the countersunk screw 8 is fitted, and the head 8 a of the countersunk screw 8 is outside the washer 7. Since it is screwed so as not to protrude from the facing surface, when the net 6 is fastened to the outer wall 1 by the washer 7 and the countersunk screw 8, the protruding thickness from the front surface of the net 6 is sufficiently small. Become. Thereby, it is not necessary to provide the recess for accommodating the washer 7 and the head 8a of the countersunk screw 8 in the outer wall 1, and construction work is easy.

  In addition, in this outer wall tiling method, the washer 7 is separate from the countersunk screw 8. For this reason, even when the countersunk screw 8 is driven obliquely with respect to the outer wall 1, the washer 7 is substantially parallel to the exterior material 4, and the net 6 can be firmly fastened by the washer 7. Further, since the washer 7 is substantially parallel to the exterior material 4, the iron is not caught when the elastic adhesive 10 is applied, and the application work of the elastic adhesive 10 can be performed smoothly.

In this reference example , since the joint tape 5 having cushioning properties is provided across the joint between the adjacent exterior materials 4, 4, each exterior material 4 expands and contracts due to a temperature change or the like, and the adjacent exterior materials 4. , 4 even when they deviate from each other, the stress applied to the tile 11 due to this deviation is absorbed by the joint tape 5, so that the tile 11 can be prevented from cracking or peeling off.

  Further, since the net 6 can be temporarily fastened via the joint tape 5, the screwing workability is greatly improved.

Figure 6 is a perspective view showing a tiled method of the outer wall of the form of implementation process.

  In this embodiment, a plurality of nets 6 are adjacently arranged in the left-right direction along the outer wall 1. Below, the arrangement | positioning procedure to the outer wall 1 of this some net | network 6 is demonstrated.

First, as in the above-described reference example , a joint tape 5 (not shown; see FIGS. 1 and 2) is pasted across the joint between adjacent exterior materials 4 and 4.

  Next, the plurality of double-sided pressure-sensitive adhesive tapes 16 are attached to the outer wall 1 so that the double-sided pressure-sensitive adhesive tape 16 extends in the up-down direction and is spaced by one net between each tape. In this embodiment, the double-sided pressure-sensitive adhesive tape 16 is formed by adhering or impregnating butyl rubber on both surfaces of a belt-like nonwoven fabric.

  Next, the first net 6 is disposed between the double-sided adhesive tape 16 and the adjacent double-sided adhesive tape 16 (not shown), and both end portions of the first net 6 are respectively attached to the respective double-sided adhesive tapes. Adhere to 16,16. Next, a second net 6 is disposed adjacent to the first net 6, and both end portions of the second net 6 are attached to the double-sided adhesive tape 16. At this time, the left end of the second net 6 is superposed from the right end of the first net 6 attached to the double-sided adhesive tape 16, and is attached to the double-sided adhesive tape 16.

  Thereafter, the tucker 15 is driven into the outer wall 1 through the left end of the second net 6, the right end of the first net and the double-sided adhesive tape 16, and these are integrally fastened to the outer wall 1.

  Thereafter, the third and subsequent nets 6 are sequentially arranged in the same procedure. It should be noted that a large number, for example, all the nets 6 may be pasted before tucking.

  After attaching the net 6 to the outer wall 1 in this way, the countersunk screws 8 are driven into the outer wall 1 through the washer 7 at a predetermined driving pitch, and each net 6 is fixed to the outer wall 1.

Thereafter, an elastic adhesive is applied and tiled in the same manner as in the reference examples shown in FIGS.

  According to the tiled construction method of the outer wall in FIG. 6, the net 6 is temporarily fastened by the double-sided adhesive tape 16 and the tucker 15, so that the net 6 can be firmly fastened. In addition, since the right end and the left end of the two nets overlap and adhere onto the single double-sided adhesive tape 16, the amount of the double-sided adhesive tape 16 used is small.
