2. Description of the Related Art Filling joints formed by injecting and filling required joint materials expand and contract the width due to temperature, humidity, vibrations of a building, and the like. Causes so-called boundary surface separation, which separates from the joint inner wall surface, which may cause rain leakage or the like. That is, although the joint material is adjusted so as to follow a certain degree of expansion and contraction, actually, when the width and the thickness have a large cross section exceeding 10 mm, for example, the joint material is faithful to the expansion and contraction of the joint. And the above-described boundary surface separation occurs. If the flexibility of the joint material is increased to improve its followability, the workability will be extremely deteriorated, and so-called sagging will occur, deform and damage the appearance, and the joint material may not fulfill its original function. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The expansion / contraction part laid in a joint a may be a solid expansion / contraction part such as a sponge body or a hollow expansion / contraction part such as a tube. May be
In the illustrated embodiment, a hollow expanding / contracting portion b is employed. The expansion / contraction part b has a structure in which a vertically elongated elliptical hollow expansion / contraction part 2 is supported via a support neck 3 along an elongated bottom plate 1 having the same width l as the joint a. The width of the hollow expansion / contraction portion 2 is set to half of the width of the joint a, that is, 1/2.

Reference numeral c denotes a construction nozzle used to fill and fill a required joint material d into a joint a on which the expansion / contraction portion b is laid and to level the surface thereof. The construction nozzle c includes a mounting tubular portion 4 and a finishing port 5 integrally formed of an elastic material such as various rubbers or synthetic resins, and forms a series of passages 6 therein.

A base 8 having a female thread 7 engraved on an inner peripheral surface thereof is fitted into the inside of the mounting cylindrical portion 4, and a core plate 9 extending from the base 8 is provided with a curved front end 9. ₁ is extended and buried in the thickness of the finishing port 5, more specifically, substantially at the center of the thickness of the bulging wall 10 continuing to the lower front side of the mounting tubular portion 4.

The finishing opening 5 is formed by the bulging wall 10, a thick wall 11 on the lower rear side, and thin walls 12, 12 on both the left and right sides.
With these lower end surfaces, a rectangular bottom opening 13 continuous with the passage 6 is formed so as to surround the lower end surface of the bulging wall 10, which is the front side edge surface of the bottom opening 13, as a finish leveling portion 14.

Further, a hanging portion 15 is provided at a required position near the bottom opening 13 of the passage 6 and relatively close to the finishing leveling section 14 in parallel with the finishing leveling section 14 and at right angles thereto. The passages 6 are provided in such a direction that the passages 6 communicate with the bottom opening 13 in a state where the passages 6 are equally divided into right and left. The sagging pieces 15 are used for roughly leveling the joint material d injected into the joint c as described later.

[0015] spacing L ₁ of the right and left sides of the thin-wall 12, 12 is a width of the finishing opening 5 is larger than the normal width of the joint a (e.g. 10 mm) (e.g. 15 mm), Therefore, both the thin walls 12, The lower end surface of the joint 12 has such a length that it can be abutted and mounted on the outer side surfaces on the right and left side edges of the joint a (FIG. 6). The width of the bottom opening 13 is set to be equal to or smaller than the normal width (for example, 10 mm) of the joint a, so that the joint material d delivered from the bottom opening 13 is accurately injected into the joint a. .

The bulging wall 10 has a sharp front edge 17 having a triangular cross section protruding from the front surface of the lower end thereof. The lower end surface of the sharpened front edge 17 is aligned with the lower end surface of the bulging wall 10, and thus the finish leveling portion 14 is substantially widened. The left and right thin walls 12, 12 have horizontal guide portions 1
8, 18 are integrally formed to extend. These spacing L ₂ between the outer end of the horizontal guide 18, 18 is considerably wider than the width of a normal joint a (e.g. 10 mm) (e.g., 15
２０20 mm) (FIG. 2).

Reference numerals 19, 19 denote guide leg pieces which are vertically provided on the left and right ends of the thick wall 11, respectively.
At least l is fitting the interval L ₃ between the outer end face with the same as the width l of the joint a, the distance L ₄ between the inner end face, in the hollow inflation and deflation portion 2 of the expansion and contraction section body b / 2 (FIG. 3).

The construction nozzle c having the above-mentioned construction is used for replenishing the joint material d each time it is used. A known joint material replenishment type caulking gun, or a joint material-filled cartridge e to be used by loading it into a known cartridge loading gun. (See FIGS. 6 and 7), and joint material d is jointed with joint a as described above.
Used for filling and leveling.

The actual joint construction, which includes laying the expansion / contraction portion b having the above-described structure in the joint a and filling the joint material d with the construction nozzle c, is as follows. Done.

The joint a is in the form of a groove, and is cleaned using a brush or the like as a pretreatment according to a customary practice. The masking tapes 20 and 20 are applied to the outer sides of both left and right edges of the joint a, and a required primer is applied inside the joint a.

Thereafter, the expansion / contraction part b is laid in the joint a (FIG. 5). Next, the guide leg pieces 19, 19 of the finishing opening 5 of the construction nozzle c are inserted into the joint a while being fitted into the hollow expanding / contracting portion 2 of the expanding / contracting portion b, and the bottom opening 13 is inserted into the joint a. And the horizontal guide portions 18, 18 are
In a state where the caulking gun or the cartridge e is in contact with the outer surfaces of the left and right edges, specifically, the masking tapes 20 and 20 stuck thereon, the caulking gun or the cartridge e is tilted by hand as shown in FIGS. To support.

In this manner, the finishing port 5 is opposed to the joint a, and the finishing port 5 is positively pressed against the joint side with a required pressing force to support the operating lever of the caulking gun or the cartridge e. By operating (not shown), the joint opening 5 is pushed out and the finishing opening 5 is moved along the joint a into the near side, that is, the arrow 21 in FIGS.
Pull in the direction.

As a result, the joint material d in the caulking gun or the cartridge e is injected and filled into the joint a through the passage 6 of the construction nozzle c and both sides of the partition piece 16, and the hollow swelling of the expansion / contraction portion b is performed. The filler material sequentially filled on both sides of the contracted portion 2 becomes the joint material d 'on both sides, and the filler material filled on the upper side of the hollow expansion / contraction portion 2 becomes the joint material d "on the opening side.

In the above, the joint material d raised on the joint a is pressed by the front hanging piece 15, and
The surface of the joint material d that has been roughened and roughened is immediately finished by the finish leveling unit 14 immediately thereafter. As a result, the thickness of the joint material d ″ on the opening side becomes approximately 5 mm (the dimensions of the relevant portions are set in advance).

By continuing the injection and filling of the joint material d and the leveling operation thereof, the masking tapes 20 and 20 are peeled off to complete the joint work, and the desired filling joint f
Can be obtained.

When the joint nozzle d is injected and filled into the joint a by the construction nozzle c, the partition piece 16 of the nozzle c is located above the hollow expansion / contraction part 2 of the expansion / contraction part b. The joint material d is diverted to both sides of the hollow expansion / contraction part 2 without directly applying a force to crush the hollow expansion / contraction part 2 from above, and the hollow expansion / contraction part 2 is brought into a normal posture. It can be buried in the joint material as it is.

The construction of the filling joint f is such that a joint material d is embedded in a joint a and an expansion / contraction part b is buried therein. It is located at the center, is filled with both-side joints d ', d' on both sides thereof, and is filled with an opening-side joint d "on the upper side, and the thickness of the opening-side joints d" is approximately 5 mm.

Therefore, when the width of the joint a expands or contracts due to the temperature, humidity, vibration of the building, or the like, the expansion and contraction portion b expands and contracts following the expansion and contraction, and the joint material d ″ on the opening side is formed. There is no so-called boundary surface peeling that expands and contracts and peels off from the joint inner wall surface.

[0029]

As is clear from the above description,
In the filled joint of the present invention, both sides of the expanded / contracted portion located at the center of the joint are filled with the joint material on both sides, and the upper side is filled with the joint material on the opening side, and the thickness of the joint material on the opening side is about 5 mm.
mm. Therefore, when the joint expands and contracts due to temperature, humidity, vibration of the building, etc., the expanding and contracting portion expands and contracts, and the joint material on both sides and the joint on the opening side expand and contract. They do not cause so-called boundary surface separation, which separates from the joint inner wall surface. In particular, the joint material on the opening side has a thickness of about 5 mm.
Therefore, the above-described expansion and contraction is performed faithfully, and the boundary surface does not separate from the joint inner wall surface.

Further, by laying and using the expansion and contraction body, the amount of joint material to be filled can be reduced and the work efficiency can be improved. Further, compared with the case where only the joint material is filled in the joint, Durability can be remarkably improved.

According to the construction method of the present invention, the filling joint having the above configuration can be constructed simply and reliably.

According to the joint nozzle of the present invention, it is easy to carry out the method of the present invention, and it is convenient to easily obtain the filling joint of the present invention.
