Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a repair method in which an adhesive is injected between an integral part of a structure and an exterior material.

In general =] In a concrete structure, the exterior of the frame 8I
For example, over the years, tithe mortar becomes old and weathered, creating gaps between the mortar pieces and sometimes causing them to flake off.

For this reason, a repair method is generally used in which an electrode I is injected into the gap between the integral part and the exterior material.

However, this method, which is commonly used, is a primitive method in which a hole is made in the exterior material of the upper and the adhesive is injected through this hole. It overflows due to internal pressure, or even if the board is filled in one minute, it overflows, resulting in the exterior wall surface being badly soiled. As a result, overflowing and overheating resulted in not using enough contact materials, which sometimes resulted in unfavorable reviews from the construction owner. Also, due to the pressure in the gap when filling the contact 644, the floating exterior sheathing may fall off during repair.

The present invention has been made in order to solve these drawbacks, and the present invention has been made by providing a plurality of small holes at appropriate intervals in order to inject the contact 144 between the structure and the exterior material. [When the board is stacked with the exterior material on the backing plate, a small hole is set in the location corresponding to the position of the small hole on the backing plate. A part of the small hole is an adhesive injection hole, a part is a bolt hole, and a part is an air vent hole, and the adhesive material in the small hole is directly connected between the patch plate and the exterior material. The area around the injection hole bolt hole and air vent hole is sealed, the backing plate is fixed together with bolts through the bolt hole, and adhesive is injected into the gap between the integral and the exterior material through the injection hole. This is a method for repairing structures.

Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a caul plate used in the present invention.The caul plate is made of a transparent PVC plate, and has a large number of small holes 2 arranged vertically and horizontally at appropriate intervals.

Figure 2 shows how the patch plate 1, which is smaller than that shown in Figure 1, is attached to the exterior N3 (described later) of a structure that requires repair, and the exterior material 2 is shown in this figure. Although it is not clearly shown in the figure, when the caul plate 1 is turned over, all or the necessary number of small holes 4 (41 & out) are set in the positions corresponding to the small holes 2 of the caul plate 1. ing. This small hole 4 directly communicates with both the small holes 2 of U & 1, as shown in Figures 3 to 6.
As shown in detail in the figure, use the bolt hole as an air vent hole [
, the adhesive can have the function of 11 holes.

In FIG. 2, the attachment of the patch plate 1 to the exterior material 3 is as follows:
A part of the small hole 1 of the cover plate 1 and a part of the small hole 4 of the exterior material 2 are used as bolt holes, and UL type steel 5, bolts 6, and strips are used.

Figure 3 shows the angle G1 of the backing plate 1 to the exterior material 2 of the structure.
This is a cross section showing the details of the part, and particularly shows the part where the small hole 2.4 is used as a bolt hole and is attached via an L-shaped steel.

The small structure in Figure 3 is made of concrete!
! 7 and an exterior material 3, and a gap 8 is created between the concrete 17 and the exterior material 3.

1. Hole-in anchors 9 are driven into the concrete wall 7 at locations corresponding to the small holes 4 provided in the exterior material 2.
A type 1 steel 5 in which the small holes 4 of the exterior material 3 and the small holes 2 of the backing plate 1 are overlapped in a suitable manner, and further bolt holes are provided.
are overlaid. Attachment to the concrete wall 7, which is the building frame, is carried out by fixing the fully threaded bolt 6 to the hole-in anchor 9 through a bolt hole such as the small hole 2.4. No. 11 is the T washer. Incidentally, if the L-shaped steel 5 is not used, both the parts and the mounting method may be the same. Here, the area around the small hole 2.4 between the exterior 443 and the backing plate 1 is sealed using clay or the like. Note that 10 is a nut.

FIG. 4 is a cross-sectional view showing the details of the structure as an air vent hole l'J in the small hole 2.4 of the cover 1 attached to the concrete wall 7 and the exterior material 3 in FIG. 3. Third
Similarly as shown in the figure, the small hole 2 of the backing plate 1 and the small hole 4 of the exterior material 3
The hole is located between the pad &1 and the exterior material 3, and the area around the hole is sealed using clay 11 as shown in FIG.

Figure 5 shows the concrete wall 7 in Figure 3 (
The structure is shown as an injection port for the lees filling material that is inserted into the small hole 2.4 of the patch plate 1 and the exterior material 3, and is basically the same as the structure of the hole 1A.

In this embodiment, a small hole 2 as an injection hole in a backing plate 1 is used.
The washer A1 and the sweat pipe 12 are installed in advance to make the parts smaller.

The present invention 44L is implemented as usual in such a structure. That is, in FIG.
As shown in the figure, connect a container etc. filled with adhesive to the washer A (12) attached to the small hole 2 of the backing plate 1, apply pressure to the container etc. [Adhesive material is sent into the gap 8 between the wall 7 and the exterior material 3.

At this time, the air in the gap 8 is discharged to the outside via the small hole 4 of the floating device 3 and the small hole 2 of the backing plate 1 as a 1-a extraction hole by feeding the adhesive material.

Then, the adhesive material that is fed in and fills the void 8 and seeks escape is discharged in the same way. At this time, there is a gap between the patch plate 1 and the exterior material 3 (small hole 2
．． The area around the hole No. 4 is sealed with clay or the like (it should not appear on the surface of Irunogu outside @ t03).The method of injecting the adhesive is not limited to the method described in this example. Of course.

After completing the injection of the adhesive into the gap 8, remove the patch plate 1 from the concrete wall 7, and clean the exterior H as required in step 11.
to complete the repair work. Note that in this figure (, A
The details are shown in FIG. 3, 8 in FIG. 4, and C in FIG. 5.

The present invention has the advantage of being constructed and implemented in this manner.

In addition, since the patch plate is stacked on the exterior material and the adhesive is injected into the gap between the one piece and the exterior material, it strengthens the exterior material and prevents the exterior material from peeling off when the adhesive is injected. can. The small holes (numbered) on the backing plate and exterior material function as bolt holes, 1A extraction holes, and adhesive injection holes, and can be used for different purposes. Between the backing plate and the exterior material (since the area around the hole is sealed, even if the excess adhesive overflows when injected, there is enough to come out on the backing plate), and the outside material is sealed. will not contaminate the surface.

In addition to the adhesive injection hole, a hole (1) is provided, so that the internal pressure when the adhesive 44 is injected can be reduced. In addition to the above advantages, it is possible to prevent staining of the exterior material due to the 43 C1 adhesive, and to reduce If and h in the gap when the adhesive is injected, so the contact material can be used safely and sufficiently, and the repair effect can be reduced by -1-min. [I can puke.] It should be noted that the purpose of using a transparent PVC machine with a saddle in this example is to enable a quick glance at the IvJ injection situation, and it goes without saying that the material is not necessarily limited to this material. ·Nor.
