Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the prevention of falling off of floating parts of facing materials (tiles, mortar, stones, etc.) that are attached to external walls of buildings, etc. It is used in construction work to prevent parts (floating parts) that are floating from the main structure sliding part (hereinafter referred to as the skeleton) such as walls or that are insufficiently connected (floating parts) from peeling off from the skeleton.

Conventionally, the method used to repair this type of floating area is to inject a wetting agent into the floating area.

Although the details of this injection method vary depending on the material of the facing material, the common point is that the gap is filled with an adhesive or the like.

For example, when the facing material is tiles, etc., the floating part of the tile is inspected, and then adhesive or filler (cement slurry) is injected with a bonder or injection machine, and the structure is Fill any gaps that arise with these materials.

In the conventional method described above, the initial state is temporarily restored,
It is possible to prevent the floating surface material from falling off. However, there is not enough confidence in the long-term effect of preventing shedding.

That is, at the time of construction, each part of the cladding material is originally firmly attached. However, with the passage of time, partial floating occurs due to structural factors of the building frame, factors on the inner surface of the cladding, etc.-C. considered to be a thing.

Therefore, even if the adhesive or injection material is completely filled into the floating part that has once occurred, there is a risk that the floating phenomenon will occur again in the long term.

An object of the present invention is to mechanically support the floating part on the frame without using adhesives, in order to stabilize the prevention of falling off by repairing the floating part over a long period of time.

A technique of a specific invention for solving the above problems The fishing rod is provided with an implanted part to be buried, and the penetrating part is provided with a covering material made of a deformable material such as rubber, and the facing material is connected to the fishing rod through the covering member. This was done so that they could come into contact with each other.

The above technical means of the present invention operates as follows.

This bottle has through holes pre-drilled in the cover material! f! The implanted portion of the tip is inserted into the building body or embedded in the structure while passing through the hole in the core. With this, when the bottle is fixed to the frame, the covering material penetrating portion near the head is inscribed in the through hole of the covering material.

Since there is a covering material made of a deformable material in the IF penetrating portion of the bottle, the first covering material and the pin main surface come into contact via this covering material, and the floating portion of the covering material is mechanically supported. This covering material is deformable and absorbs the difference in thermal expansion between the frame and the facing material when heating and cooling are repeated.

This specific invention has the following unique effects.

(1) Since the floating part is mechanically supported by the frame via a bottle having a predetermined rigidity, it is possible to stably prevent the floating part from falling off over a long period of time, regardless of whether the bonding conditions of the floating part are suitable or not.

(2) Since the bottle and the facing material will be in contact with each other with a flexible structure, this will absorb the misalignment between the floating facing part and the building frame due to the difference in thermal expansion, and the support tilt due to the rigid structure can be absorbed. Cracks in the facing material caused by differential thermal expansion.

Accidents such as damage can be prevented.

Next, the structure of the invention of the repair power υ using the above-mentioned specific invention will be explained.

In this structure, a hole is formed from the surface material of the floating part to the structure, a through hole is formed in the surface material and a hole is formed in the structure, and a bottle is inserted through the hole through the hole. and the through hole and t/i are brought into contact with each other through a covering material made of a deformable material coated on the hinge, and on the other hand, the implanted part provided at the tip of the pin is connected to the IIJ hole part through a plug to the main body. This can be done by mechanically embedding or using an adhesive to bury and fix the floating surface, and then filling the floating gap with an adhesive or a filler.

According to the above configuration of the present invention, the following effects can be obtained.

The facing material of the floating part is placed on the support N with the same effect as in the specific invention, and the floating space is closed with adhesive or injection agent. ,!:Become.

Therefore, after installation, the cladding material of the floating part will be attached to the building frame with a bottle.
It is mechanically bonded and supported and also bonded by adhesive or injection. If there is a crack in the body of the floating part, the crack is closed by injection of the mJ enthesis or injection agent.

This invention has the following unique effects.

According to this construction method, the floating cladding and the building frame are mechanically connected and supported by Yoshii, and the building body and cladding are also bonded by adhesive or injection agent, which further improves the strength of the repair and prevents it from falling off. is stable over a long period of time.

In the case of the conventional injection method, skill is required to set the injection pressure of the adhesive or filler, but in the case of the method of the present invention, the holding strength of the facing side is ensured by mechanical holding by the queen bottle. There is no need to increase the adhesive strength of the adhesive or injection agent, and there is therefore more leeway in setting the pressure during injection.

In addition, if the amount of adhesive or injection agent filled is excessive, the floating part may float abnormally due to this injection operation, causing it to split or peel. Because it is supported by the facing material or the skeleton,
Such inconveniences are also less likely to occur. In this respect as well, the work is easy and does not require skill.

Furthermore, even if the bonding conditions of the floating part are poor, since the floating surface material is not bonded by adhesion, the surface material can be reliably connected to the building frame.

An embodiment of the present invention will be described below based on the drawings.
