Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for repairing an exterior wall, and more specifically, for example, in an existing exterior wall in which a tile block wall is provided on the outdoor side of a building frame, the present invention relates to a method for repairing an exterior wall. This relates to a repair method when a part of the surface has fallen off.

[Conventional technology]

If a part of the tile block has fallen off in an existing exterior wall where a tile block wall has been constructed on the outdoor side of the building frame, conventionally, the tile block part that has fallen off or the tile block area including the surrounding area should be re-installed. The repair method used is to reinstall similar tile blocks.

[Problem that the invention seeks to solve]

However, such conventional repair methods have the following problems.

In other words, (a) In general, the tile block wall of the existing exterior wall is often a long time old since it was installed, and therefore the tile block wall that has fallen off has the same shape and pattern as the tile block wall that has fallen off. It is difficult to obtain tile blocks for repair, so in this case,
The only option is to demolish and repair the entire surface of the block wall, which is undesirable from a cost perspective.

(b) In addition, even if a tile block with the same shape and pattern as the fallen tile block can be obtained, the existing one will naturally have deteriorated over time, and a new tile block will be replaced within this aged tile block. It is unsightly in terms of design to have a mixture of these.

(c) In addition, if some of the tile blocks on the existing exterior wall come off, the durability or weather resistance of the entire tile surface or the area around the peeled off area may deteriorate.
This indicates damage, and even after repair,
New flaking is likely to occur, so it is not necessarily an effective countermeasure.

Further, even if the existing exterior wall is a mortar wall, a portion of the mortar may peel off, causing a problem similar to that of the tile block wall described above.

The present invention solves the above-mentioned problems, and when a part of the members constituting the exterior wall such as the existing exterior wall such as tile block wall, mortar wall tiles, mortar, etc. peels off, etc. An exterior that can be radically renovated into a new tile block wall easily and in a short period of time, and also prevents defects such as tile blocks, which are part of the existing exterior wall components, from falling off during and after the repair. The purpose is to provide a method for repairing walls.

[Means for solving problems]

In the method for repairing an exterior wall according to the present invention, a plurality of mounting members placed on the outdoor side of the existing exterior wall are attached to the building frame using a fixture that penetrates the existing exterior wall installed on the outdoor side of the building frame. The method is characterized in that after the existing exterior wall is held down by each of the mounting members, a new tile block wall is constructed on the outdoor side of the mounting members and supported by the mounting members.

[Effect]

In the method for repairing an exterior wall according to the present invention, since a plurality of mounting members are fixed to the building frame using fixing devices that penetrate the existing exterior wall, the mounting members can be firmly fixed. By strongly pressing the existing exterior wall such as a tile block wall from the outdoor side against the outdoor side of the frame using the members, the members such as the tile block that make up the existing exterior wall are attached to the new block wall after the mounting members are fixed. It is possible to suppress problems such as peeling during the construction of new block walls and after construction of new block walls.

Furthermore, the repair method according to the present invention is to construct a new block wall on the outdoor side of these walls using mounting members, and the mounting members repair the above-mentioned peeling off of a part of the members constituting the existing exterior wall. Since it has both the function of suppressing the load and the original function of supporting the load of the new block wall on the frame, the number of parts is relatively small, and all remaining tile blocks from the existing exterior wall are removed before the new block wall is installed. Without the hassle of constructing a tile block wall,
The existing exterior wall can be repaired easily and in a short period of time, and the new tile block wall has a good appearance because the existing tile block and new tile block are not mixed, and the new tile block is not only new.

〔Example〕

Hereinafter, embodiments of the method for repairing an exterior wall according to the present invention will be described in detail with reference to FIGS. 1 to 5.

Figures 1 and 2 are perspective views and partially enlarged cross-sectional views showing the general structure of the exterior wall of a building to which the repair method of the first embodiment is applied, and Figure 3 is a partial enlarged sectional view of a building constructed on the outdoor side of the existing exterior wall. FIG. 2 is an exploded perspective view for explaining the procedure for constructing a newly installed tile block wall.

In each figure of the first embodiment, as the frame of the building 1, the outer wall surface 2a of the reinforced concrete wall 2 includes:
The individual tile blocks 4 constituting the existing tile block wall 3 are stretched with mortar cement 5 or the like as an adhesive, and the joints between them are filled with white cement 6 or the like as a joint material. .

In the present invention, in the case of an exterior wall made of tile block wall 3 of building 1 constructed as described above, if a part of the tile block 4 comes off or is missing, it becomes necessary to replace the wall. In such a case, a tile block repair method will be discussed in which a new tile block wall 8 is constructed on the outdoor side of the existing tile block wall 3. In order to fix the newly installed tile block wall 8 to the reinforced concrete wall 2 serving as the framework, fixing receivers 7 such as anchor nut members occupying a plurality of predetermined positions and penetrating the existing tile block wall 3 are installed at each of the predetermined positions. Push it in firmly to secure it. In addition,
Here, the symbol a is a space created by some of the tile blocks 4 coming off.

In the case of the repair method of the first embodiment, the newly installed tile block wall 8 is constructed of the following members.

That is, each tile block 9 consists of a main body 9a formed in an elongated rectangular shape, and an exterior wall 9b of the same shape that is integrally molded and shifted vertically and horizontally by intervals A and B with respect to the main body 9a. The main body part 9a is made of a fired body such as ceramic, and on the back side where the main body part 9a is attached, a so-called dovetail-shaped engagement groove 10 having wedge-shaped engagement grooves 10a and 10b on the upper and lower inner sides, respectively, is formed in the left and right direction. formed into
And the back ridges of the main body part 9a are each chamfered 1.
1 and 11.

In addition, the face plate 12 is made of a metal plate such as a steel plate,
By roll forming or the like, a series of engagement protrusions 13 extending in the left-right direction are formed corresponding to the engagement grooves 10.
The tile blocks 9 are integrally formed at predetermined intervals such that they abut each other in the vertical direction, and slit-shaped locking holes 14 are formed at predetermined positions in the left and right direction between each engagement convex portion 13. Each of the engaging convex portions 13 has an inner locking groove 13b on the upper side thereof, and has an inner locking groove 13b located diagonally upwardly for locking the upper engaging groove portion 10a of the tile block 9. forming an upper engaging protrusion 13a projecting from the upper engaging protrusion 13a;
located on the lower side and protrudes diagonally downward so as to face the lower engagement groove 10b of the tile block 9;
Each of the lower engagement protrusions 13c has an outer locking groove 13d at its protruding base.

The fixing key 15 is driven between the lower engagement groove 10b of the tile block 9 and the outer engagement groove 13d of the face plate 12, and is formed into a shape that allows them to be fixedly engaged with each other.

Further, the long mounting member 18 has a central protrusion 1 that stands up from the flange portions 18b, 18b.
8a, each engaging protrusion 13 on the face plate 12
At positions corresponding to the inner locking groove 13b and each locking hole 14, an engaging piece 19 extending diagonally upward for locking with the former inner locking groove 13b is provided.
and a stopper piece 20 for inserting the latter stopper hole 14 are cut and raised, respectively.

The repair work of the existing tile block wall 3 with the newly installed tile block wall 8 using each of the above-mentioned constituent members is carried out as follows.

First, a plurality of mounting members 18 are attached and arranged at predetermined intervals in the left and right directions so as to extend in the vertical direction on the outdoor wall surface of the existing tile block wall 3 to be repaired. The flange portions 18b, 18b are properly fastened and fixed to the fixing receiver 7 using fixing tools 21 such as bolts. That is, each attachment member 1 to the outdoor side wall surface of the existing tile block wall 3
8, it is possible to suppress and reinforce the tile block from peeling off after the attachment member 18 is attached from the outdoor side wall surface, and each of these attachment members 18 itself can be used to attach the new tile block wall described below. This serves as a base member for tensioning and mounting the body 8.

Next, each mounting member 18 extending in the vertical direction and attached at predetermined intervals in the left and right direction includes:
The locking grooves 13b formed in the engagement convex portions 13 on the face plate 12 are inserted into these cut-and-raised protrusions 19 from diagonally above to be hooked and locked, and the cut-and-raised stopper pieces 20 through the locking hole 14 and by folding and bending the cut-and-raised stopper piece 20, the face plate 12 can be attached to the entire surface of the outdoor side of each mounting member 18 without using separate bolts or the like. Let it be stretched. That is, by clearly separating the plastering work in tile block construction described below from the installation work using jigs and tools, it is possible to improve workability and efficiency. At the same time, the face plate 12 stretched as described above serves as a reinforcing base for mounting each tile block 9, and the space between the back side of the face plate 12 and the existing tile block wall 3 is provided with appropriate heat insulation. Interposing the material 22 is also effective in improving the heat insulation effect.

The tile blocks are stretched onto the face plate 12 by applying the upper engagement protrusions 13a of the engagement protrusions 13 formed on the surface (outdoor side surface) to the reference row of the engagement protrusions 13. , first tile block 9
The upper engaging groove 10a is hooked and engaged, and the lower engaging groove 10b is opposed to the lower engaging protrusion 13c, and positioned at the reference position, and one edge side of the fixed key 15 is engaged downward. Protrusion 13c
Insert the other edge side into the outer locking groove 13d of the lower engaging groove 1.
0b, and drive it in place about halfway to fix it.

Furthermore, based on the fixed position of the first tile block 9, the next tile block 9 adjacent to the same engagement protrusion 13 in the same row, that is, the reference row, is hooked and engaged in the same manner, until about halfway up the previous tile block 9. Push in the fixed key 15 while making sure that the unpierced part of the fixed key 15 is received on one end side, and abut the left and right uneven parts on the same end side so that they overlap each other, and then press the key 15 in the same way from the other end side. The next fixing key 15 is driven in about half way to fix it, and this is successively repeated to position and fix the tile blocks 9 in the same row.

Subsequently, for the tile blocks 9 in the next and subsequent rows adjacent to the reference row, the upper and lower uneven portions of the adjacent rows are matched so as to overlap each other, and then the fixed keys 15 are pressed in the same manner to sequentially tile blocks 9. In this way, the tile blocks 9 are stretched on the surface of the face plate 12 in a zigzag pattern or in any other desired pattern.

As described above, when each tile block 9 is stretched over each engaging convex portion 13 on the face plate 12, the tile blocks 9 adjacent to each other in the left and right direction corresponding to each engaging convex portion 13 are arranged as follows. The tile blocks 9 which are connected and fixed by the engagement of the engagement groove 10 with the engagement convex portion 13 and the driving of the fixing key 15, and which are adjacent to each other in the vertical and horizontal directions, are The overlapping parts, that is, the gaps A and B given to the main body part 9a and the exterior part 9b, are overlapped to form a good bond, and bonding with an adhesive and filling with joint material as in the past is not possible. Stable tensioning of the tile block 9 can be carried out effectively and easily without the need for this.

In addition, by forming several thin ridges 9c in advance in the overlapping portion, several water return spaces 23 can be formed between the overlapped portions, which not only achieves an effective waterproofing effect, but also can be used as needed. One way to obtain a waterproof effect is to appropriately interpose packing material, caulking material, etc. between the same parts.

In addition, in the repair method of the first embodiment shown in FIGS. 1 to 3, the case where no joint grooves are formed between the tile blocks 9 has been described, but the repair method shown in FIGS. 4 to 6 As in the repair method of the second embodiment, the joint protrusion 16 is made to protrude from the middle part of the fixed key 15, and the engagement protrusion 1 of the face plate 12 is
By setting the interval between the grooves 3 to a predetermined dimension, the joint groove 23 can be easily formed and the joint material 24 can be filled as appropriate. Furthermore, the tile block 9 does not necessarily have to have a shape in which the main body part 9a and the exterior part 9b are offset, and a simple rectangular shape as shown in FIG. 7 may be used.

In the above explanation, the existing tile block wall 3 was mainly explained as the existing exterior wall, but the repair method of the present invention can be applied to any existing exterior wall that needs to be held down with a mounting member such as a mortar wall. can do.

It is also possible to replace the newly installed tile blocks with lightweight materials other than ceramic tiles, such as compressed tiles using the trade name Particle Board, metal panels, etc.
