[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for repairing a tile wall lifted from a concrete frame.
[0002]
[Prior art and problems to be solved by the invention]
The tile walls that cover the concrete frames of buildings such as buildings and retaining walls may sometimes rise from the concrete frame over time. It has been done.
However, such a repair method has a problem in that an old tile wall and a new tile wall coexist, so that the color varies, the appearance is deteriorated, and the repair cost is high. In addition, for historical buildings, tiles of the same color are often not available, and there is a problem that the repair is difficult.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a tile wall repair method capable of repairing a tile wall floating from a casing without peeling off the tile wall.
[0003]
[Means for Solving the Problems]
In order to achieve the above object, the tile wall refurbishing method of the present invention is characterized in that a first hole for driving an anchor nut is formed in a joint portion of the tile wall in the tile wall and the casing covered with the tile wall. Along the step of forming at predetermined intervals along,
Forming a second hole for filling the adhesive between the back surface of the tile wall and the tiled surface of the casing along the joint at predetermined intervals;
Driving an anchor nut into the first hole;
Attaching the abutting member to the tile wall by screwing an anchor bolt into the anchor nut along the abutting member for each tile wall divided into a plurality of sections,
Separating the tile wall into a plurality of sections;
Retightening the anchor bolts for each section of the separated tile wall, and pressing the tile wall against the tiled surface of the cabinet for each section;
Filling the adhesive between the back surface of the tile wall and the tiled surface through the second hole with the tile wall pressed against the tiled surface;
Removing the anchor bolt and the abutting member after filling the adhesive;
Filling the first hole after removing the anchor bolt with a filler;
Filling the second hole with a filler after filling with an adhesive; and
Filling a boundary portion of each section of the separated tile wall with a filler (claim 1).
[0004]
According to the tile wall refurbishing method having such a structure, the tile wall that has been lifted from the casing can be bonded to the tiled surface of the casing by the adhesive filled through the second hole. The tile wall that has been lifted can be repaired without using. Moreover, since the tile wall is pressed against the tile pasting surface for each section in a state where the tile wall is separated into a plurality of sections, the entire tile wall can be uniformly pressed against the tile pasting surface. Furthermore, since the adhesive is filled between the back surface of the tile wall and the tile-attached surface while the tile wall is pressed against the tile-attached surface of the cabinet, it is possible to prevent the adhesive from causing irregularities on the tile wall. it can.
[0005]
In the tile wall renovation method, it is preferable to use a grease-coated anchor bolt (Claim 2). In this case, it is possible to prevent the adhesive from adhering directly to the anchor bolt. Therefore, the anchor bolt can be easily removed from the first hole.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
1 to 9 are process diagrams showing a tile wall repair method according to the present invention. In this repairing method, first, as shown in FIG. 1, a parting line 1 is written with a chalk or the like on a tile wall A partially lifted from a housing B of the building, and the tile wall A is divided into a plurality of parts. The size of each section is, for example, about 1 m long and 2 m wide.
[0007]
Next, first holes 4 for driving anchor nuts 6 (see FIG. 5) are formed in the tile wall A and the casing B along the joint portions M of the tile wall A at predetermined intervals (see FIG. 5). (See FIG. 2). The first hole 4 is formed by drilling the tile wall A portion and the frame B portion in series with a drill. The formation pitch of the first holes 4 is, for example, 50 cm in the vertical direction and 1 m in the horizontal direction. Note that a mortar layer C for tile adhesion remains between the tile wall A and the tile attachment surface B1 on the surface of the casing B (see FIG. 3).
[0008]
Furthermore, the 2nd hole 5 is formed for every predetermined interval along the predetermined joint part M of the said tile wall A (refer FIG. 2). The second holes 5 are for filling the adhesive 10 (see FIG. 6) between the back surface of the tile wall A and the tile attaching surface B1 of the casing B, and the formation pitch thereof is, for example, in the vertical direction. The horizontal formation position is a joint portion M located in the middle of each joint portion M in which the first hole 4 is formed. Further, the second hole 5 is drilled obliquely downward with respect to the tile wall A in a state where the mortar layer C is penetrated (see FIG. 6). Any of the first hole 4 and the second hole 5 may be formed first.
[0009]
When the formation process of the first hole 4 is completed, the anchor nut 6 is driven into each first hole 4 (see FIG. 3). The anchor nut 6 is formed with a plurality of slits 6a extending in the axial direction, and the diameter of the anchor nut 6 is increased by screwing in an anchor bolt 7 to be described later, so that the anchor nut 6 is prevented from being removed from the first hole 4. A part of the anchor nut 6 on the head side protrudes from the housing B into the tile wall A.
When the formation process of the second hole 5 is completed, a filling plug 9 made of an acrylic resin pipe is driven into the second hole 5 (see FIG. 6). The head side of the filling plug 9 is projected from the tile wall A by a predetermined length.
[0010]
Next, a contact member 8 made of a wooden square member is attached to the tile wall A using anchor bolts 7 (see FIGS. 4 and 5). The length of the abutting member 8 is slightly shorter than the longitudinal length of each section of the tile wall A, and the abutting member 8 is attached to each longitudinal column of the first holes 4 in each section of the tile wall A. . At this time, the anchor bolt 7 is inserted into a through-hole formed in the abutting member 8 in advance, and its tip is screwed into the anchor nut 6. The anchor bolt 7 is lightly fastened to the anchor nut 6. The anchor bolt 7 is screwed into the anchor nut 6 in a state where grease is applied in advance.
[0011]
When the attachment of the contact member 8 is completed for all sections of the tile wall A, the tile wall A is separated for each section (see FIG. 7). This cutting operation is performed by cutting the tile along the dividing line 1 with, for example, a sander. At this time, since the tile wall A is supported by the anchor bolt 7 and the abutting member 8, it is possible to prevent the tile wall A from being peeled off by vibration.
[0012]
Next, the anchor bolt 7 is tightened for each section of the separated tile wall A, and the tile wall A is pressed against the tile attaching surface B1 of the casing B for each section. Thereby, the tile wall A floating from the tile pasting surface B1 can be brought into close contact with the tile pasting surface B1. Further, since the tile wall A is pressed against the tile pasting surface B1 for each section, the entire tile wall A can be easily and uniformly pressed against the tile pasting surface B1.
[0013]
When the tightening of the anchor bolts 7 is completed for all the sections of the tile wall A, for example, an epoxy resin adhesive 10 is applied to the back surface of the tile wall A and the tile attachment surface through the filling plug 9 driven into the second hole 5. B1 is filled (see FIG. 6). Thereby, the adhesive 10 can be permeated into the gap between the back surface of the tile wall A and the tile attachment surface B1 to bond them together. Thus, since the adhesive 10 is filled in a state where the tile wall A is pressed against the tile attachment surface B1, the amount of the adhesive 10 used can be reduced. When the adhesive 10 is filled with the tile wall A floating from the tile attachment surface B1, not only a large amount of the adhesive 10 is required but also a large amount of adhesion between the tile wall A and the tile attachment surface B1. The agent remains, and the tile wall A becomes uneven.
[0014]
When the filling of the adhesive 10 is completed for each filling plug 9, the anchor bolt 7 is removed and the abutting member 8 is removed from the tile wall A. At this time, the adhesive applied to the anchor bolt 7 is prevented by the grease applied to the anchor bolt 7, so that the anchor bolt 7 can be easily removed from the first hole 4.
Further, with respect to each first hole 4 from which the anchor bolt 7 has been removed, the filler 11 is injected into at least a predetermined area on the opening side, and the first hole 4 is filled with the filler 11 (see FIG. 8). Moreover, the part which protruded from the tile wall A of the filling plug 9 is cut and removed, the filling material 11 is inject | poured into the predetermined area | region of the opening side, and the 2nd hole 5 is filled with the said filling material 11 (refer FIG. 9). . Thereafter, the groove (see FIG. 7) of the boundary portion 12 of each section of the separated tile wall A is filled with the filler 11.
The filler 11 is of the same color as the joint M so that the traces of the first hole 4 and the second hole 5 are not noticeable.
[0015]
According to the tile wall repairing method comprising the above steps, the tile wall A that has been lifted from the housing can be used for repair as it is, so that the color of the tile wall A can be prevented from varying and the same. Historical buildings where it is difficult to obtain colored tiles can be easily repaired.
In addition, about the construction order of the repair method of the tile wall of this invention mentioned above, it can change suitably besides the above and can implement.
[0016]
【The invention's effect】
As described above, according to the method for repairing a tile wall according to claim 1, the tile wall floating from the housing can be repaired without using a new tile. In addition to preventing deterioration, it is also possible to easily refurbish historic buildings and the like where it is difficult to obtain tiles of the same color without greatly impairing the texture.
In particular, since the tile wall is separated into a plurality of sections and pressed against the tiled surface for each of the sections, the entire tile wall can be evenly pressed against the tiled surface even with a large area. As a result, it is possible to prevent unevenness from occurring. In addition, since the adhesive is filled between the back surface of the tile wall and the tile attaching surface while the tile wall is pressed against the tile attaching surface of the housing, it is possible to prevent the tile wall from being uneven due to the adhesive. it can.
[0017]
According to the tile wall refurbishing method of the second aspect, since the anchor bolt coated with grease is used, it is possible to prevent the adhesive from adhering directly to the anchor bolt. For this reason, the said anchor bolt can be easily removed from a 1st hole, and the construction man-hour can be reduced by that much.
