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, the present invention relates to a method for repairing an exterior wall of a building covered with tile blocks, where a portion of the tile blocks have fallen off.

[Conventional technology]

When a part of a tile block falls off on an exterior wall of a building covered with tile blocks, conventionally, the same tile block is replaced with the same tile block for the peeled off tile block part or the tile block part including the surrounding area. A repair method has been adopted that involves re-stretching.

[Problem that the invention seeks to solve]

However, such conventional repair methods have the following problems.

Namely.

(a) In general, existing tile blocks are often a considerable amount of time since they were installed, and for this reason, it is difficult to obtain tile blocks with the same shape and pattern for repair. Therefore, in this case, the only option is to demolish and repair the entire surface of the block, which is undesirable from the cost standpoint.

(b) Even if tile blocks with the same shape and pattern can be obtained, the existing ones have deteriorated dramatically over time, and new ones may be mixed in with the existing tiles and It is unsightly in terms of design.

(C) Furthermore, partial peeling of the exterior wall tile surface suggests deterioration or damage to the fire resistance or weather resistance of the entire tile surface or around the peeled part, even after repair. It is difficult to say that this is necessarily an effective measure as new flaking is likely to occur.

etc.

In view of these conventional problems, this invention provides an existing tile exterior wall 1 mortar exterior wall, ALC version, which allows the exterior wall tile surface to be fundamentally renovated when a part of the exterior wall tile surface falls off. The purpose of this invention is to obtain a method for repairing tile blocks on exterior walls.

[Means for solving problems]

In order to achieve the above object, the tile block repair method for an exterior wall according to the present invention is such that a new tile block wall surface of an independent structure is constructed in contact with the existing exterior surface, and the existing wall is not repaired. In the case of installation, a member is provided for multiple installations that penetrate the existing wall and are fixed to the building frame, each of these installations is made to hold down the same existing wall with the member, and each installation is performed by attaching a new tile to the member. This is a tile block repair method for an exterior wall, characterized by constructing a block wall body and fixing the installation.

[For production]

In other words, in the method of this invention, each of these pieces is attached after the existing wall such as an existing tile block wall that has partially fallen off is restrained by a member. Since a new tile block wall is constructed using the members, each installation will depend on the pushing of the existing wall by the members, for example, in the case of an existing tile block wall, the problem of subsequent peeling of the tile block, etc. It can be suppressed and reinforced, and each of these attachments allows a new tile block wall to be constructed for the member, making it possible to repair the exterior wall as desired.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the method for repairing tile blocks for exterior walls according to the present invention will be described in detail with reference to FIGS. 1 to 5.

1 and 2 are a perspective view and a partially enlarged sectional view showing the general structure of the exterior wall of a building to which the method of the first embodiment is applied;
FIG. 3 is an exploded perspective view for explaining the procedure for constructing a new tile block wall to be constructed on the existing tile block wall surface.

In each figure of the first embodiment, as the frame of the building (l), for example, in this case, the outer wall surface (2a) of the reinforced concrete wall (2) has an existing tile block wall (3) which is an example of an existing wall. As is well known, the individual tile blocks (4) are stretched with mortar cement (5) as an adhesive, and white cement (6) as a joint material is applied to the joints. etc. is filled.

In this invention, - For example, in the exterior wall consisting of the tile block wall (3) of the building (1) configured in this way, a part of the tile block wall (4) is peeled off or missing, Or, in a broad sense, for the purpose of repairing the case where it has become soiled to the point that it needs to be replaced, a new tile block wall (8) is constructed on the outer wall surface of the existing tile block wall (3). I decided to do so. In a narrow sense, it deals with the method of installing tile blocks, and in order to fix the newly installed tile block wall (8) to the reinforced concrete wall (2) as the framework, the existing tiles are placed at a plurality of predetermined positions. Firmly drive and fix the fixing receiver (7) such as an anchor nut member that penetrates the block wall (3).
is a space created by a part of the tile block (4) falling off.

As you can see, the newly installed tile block wall (8) is this first
In the case of the method of the embodiment, it is composed of the following secondary members.

i.e. two individual tile blocks (9) in this case:
A main body (9a) formed in an elongated rectangular shape, and an interval (A) in the vertical and horizontal directions with respect to the main body (9a).

It is made of a fired body such as ceramic with an exterior part (9b) of the same shape that is integrally molded with a difference in height by (B). The retaining groove (IQa), (10b)
has. A so-called dovetail-shaped engagement groove (10) is formed in the left-right direction, and the rear edge of the main body (8a) is chamfered (11), respectively.

The face plate (12) is made of a metal plate such as a steel plate, and is formed by roll forming or the like to form a series of engagement convex portions (13) extending in the left-right direction corresponding to the engagement grooves (lO) on the tile. The blocks (8) are integrally formed at predetermined intervals such that they abut each other in the vertical direction, and each engagement convex portion (13)
Slit-shaped locking holes (14) are drilled at predetermined positions in the left and right direction between the two, and each engaging protrusion (13) has an inner locking groove on the upper side. (13b) and protrudes obliquely upward for locking the upper engaging groove (10a) of the tile block (9).
a), and the same tile block (
9) A lower engagement protrusion (13c) is formed on each of the lower engagement grooves (13c) that protrudes diagonally downward to face the lower engagement groove (10b) and has an outer locking groove (13d) at the base of the protrusion.

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

For longer installations, the member (18) must be attached to its flange (
18b), the central protrusion (18a) raised from (18b)
), each engaging protrusion (13) on the face plate (12)
An engagement piece (ia) extending diagonally upward for locking the former inner locking groove (13b) at a position corresponding to the inner locking groove (13b) and each locking hole (14), respectively.
, a stopper piece (for inserting the latter stopper hole (14)
20) are cut and raised respectively.

However, a tile block wall (
8) to repair the existing tile block wall (3), and further repair each tile block (9) by this method of the first embodiment.
) The tensioning and assembly work is carried out as follows.

First, each of the plurality of members (18) is attached to the outer wall surface of the existing tile block wall (3) to be repaired at predetermined intervals in the left and right directions so as to extend in the vertical direction. and each flange part (18b), (1
8b) is firmly tightened to the fixing receptacle (7) using a fixing device (21) such as a bolt to secure the attachment.

That is, each installation of the existing tile block wall (3) to the external wall surface can be reinforced by pressing the member (18) to suppress subsequent peeling of the tile block from the external wall surface, and each of these installations can be reinforced. Each of the members (18) itself serves as a base member for the tension installation of the new tile block wall (8) described below.

Next, each attachment member (18) extending in the vertical direction and attached at predetermined intervals in the left and right direction has an engaging protrusion on the face plate (12) with respect to the cut and raised protrusion (18). Part (13
) are inserted diagonally from above into the respective locking grooves (13b) to lock the hooks, and at the same time, insert the locking hole (14) into the cut-and-raised stopper piece (20), and By folding and bending the cut-and-raise stopper piece (20), the face plate (12) is stretched over the entire surface of the member (18) for each installation without using bolts or the like. In other words, it is possible to clearly distinguish the so-called plastering work in tile block construction described below from the installation work using jigs and tools, thereby improving workability and efficiency. The face plate (12
), in this case, each tile block (9) will be installed as a reinforcing base, and on the back side of this face plate (12), in the space between it and the existing tile block wall (3), an appropriate heat insulating material will be installed. (22) is also effective in improving the heat insulation effect.

The tile blocks are placed on the face plate (12) as follows:
Of the engaging protrusions (13) formed on its surface,
The upper engagement projection (13a) of the retention projection (13) serving as the reference row
) in the upper engagement groove (1) of the first tile block (8).
0a) is engaged with the hook, and the lower engagement protrusion (13c)
Position the fixing key (15) at the reference position with the lower engagement groove (10b) facing the outer engagement groove (L3d) of the lower engagement protrusion (13c). Insert the edges into the lower engagement grooves (10b) and drive in about halfway to secure them.

Further, based on the fixed position of this first tile block (8), the same engagement protrusions (13) are located in the same row, that is, the reference row.
In the same way, engage the next tile block (8) adjacent to the hook, and push the fixed key (15) into one end so that the unpierced part of the fixed key (15), which was driven in about half way, is received at one end, and the same end. After pressing the left and right uneven parts on the side so that they overlap each other and abutting each other, similarly drive the next fixing key (15) from the other end to about halfway and fix it.
This is repeated in sequence to fix all the tile blocks (9) in the same row.

Next, the tile blocks (9) in the next and subsequent rows adjacent to the reference row are matched so that the upper and lower uneven parts of the adjacent rows overlap each other, and then the fixed key (15) is pressed in the same manner. It is sequentially positioned and fixed by driving, and in this way, a staggered pattern is formed on the surface of the face plate (12).
Other tile blocks with arbitrary tension pattern shapes (9)
It is the construction of the

In this way, each retaining convex portion (1) on the face plate (12) is
3), when each tile block (8) is stretched, the adjacent tile blocks (9) in the left and right direction corresponding to each engaging convex part (13) are connected to each other by the engaging convex part (13). The tile blocks (9) adjacent to each other in the vertical and horizontal directions are connected and fixed by the engagement of the engagement groove (10) and the driving of the fixing key (step 5). teeth,
The overlapping parts, that is, the intervals (A) and (B) given to the main body part (9a) and each of the exterior parts (9b), are overlapped to form a good bonding mode, and adhesives are not applied as in the past. Stable tensioning can be done effectively and easily without any need for adhesion or filling with joint material.

Also, at this time, by forming several thin ridges (8C) in advance in the overlapped portion, several water return spaces (23) can be formed between the overlapped portions, resulting in an effective waterproofing effect. In addition to this, it is also possible to provide a waterproof effect by interposing a backing material, kneeling material, etc. between the same parts as necessary.

Furthermore, in the method of the first embodiment shown in FIGS. 1 to 3, the case was described in which no joint grooves were formed between the tile blocks (8), but the method shown in FIGS. 4 to 6 As in the second embodiment method, the fixed key (15)
The joint groove (23) can be easily formed by protruding the joint convex part (1B) from the middle part of the face plate (12) and setting the interval between the engaging convex parts (13) of the face plate (12) to a predetermined dimension. Then, 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 (3a) and the exterior part (9b) are offset, and a simple rectangular shape as shown in FIG. 7 may also be used. good.

In the above description, the existing tile block wall (3) was mainly explained as the existing wall, but the method of the present invention can also be applied to concrete walls, mortar walls, metal plate walls, ALC plate walls, water walls, plywood walls, etc. It can be applied to any of the following.

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.

〔Effect of the invention〕

As detailed above, according to the method of the present invention, when repairing an existing wall, a member is provided to attach multiple pieces that penetrate the existing wall and are fixed to the building frame, and each of these The outer surface of the existing wall was held down by the member, and each installation was done by constructing a new tile block wall on the member and fixing the installation, so each installation was done by holding down the existing wall with the member. , the subsequent peeling of the tile block, deterioration of the durability or weather resistance of the entire tile surface, damage, etc. can be sufficiently suppressed and reinforced, and each of these installations can be done by constructing a new tile block wall against the member. This makes it possible to restore the desired exterior wall without having to take the trouble of tearing down the entire surface of the block.Furthermore, since the entire tile block wall is newly constructed, the exterior design On the other hand, there are no particular problems, and it has excellent features such as being able to construct an exterior wall with an elegant appearance.
