The finishing opening 2 is formed by the bulging wall 7, the lower rear thick wall 8, and the lower left and right thin walls 9, 9 having lower end surfaces 7 ₁ , 8 ₁ , 9 ₁ , 9 thereof. the 9 _1, the bottom opening 10 of rectangular contiguous to the passageway 3 surrounds formed, and the lower end face 7 ₁ finishing leveling unit 13 of the bulging portion 7 is front periphery surface of the bottom opening 10. The three sides surrounding the bottom opening 10, that is, the lower end faces 7 ₁ , 9 ₁ , 9 ₁ forming the front side and the left and right sides are formed to be the same plane. In contrast, one of the remaining bottom opening 10, i.e., the lower end face ₈₁ which forms the front side, the lower end face _71,
9 _1, 9 ₁ from being formed in the upper position, thus, the receiving port in the front of the bottom opening 10 opens outwardly b
The present invention has one emphasis on the provision of the receiving port b.

The distance L ₁ (FIG. 1) between the left and right thin walls 9, 9 which is the width of the finish opening 2 is larger than the normal width of the joint c (eg, 10 mm) (eg, 15 mm). The lower end surfaces 9 ₁ , 9 ₁ of the thin walls 9, 9 have such a length that they can contact the outer surfaces of the right and left side edges of the joint c. The width of the bottom opening 10 is set to be smaller than the normal width (for example, 10 mm) of the joint c.
The joint material discharged from the bottom opening 10 is accurately injected into the joint c.

The passage 3 has a front edge that is continuous with the bottom opening 10 hangs down into the bottom opening 10 to form a rough edge 1.
It is set to 1. The rough edge 11 is used for roughing the joint material injected into the joint c as described later.

The bulging wall 7 has a sharp front edge 12 having a triangular cross section protruding from the front surface of the lower end thereof. The lower end surface 12 ₁ of the sharp leading edge 12 is the lower end face ₇₁ and engages the protruding wall 7, so that is spread substantially the finishing leveling unit 13.
As described above, forming the sharp front edge 12 on the front surface of the lower end of the bulging wall 7 is also one of the important points of the present invention.
The left and right thin walls 9, 9 have horizontal guide portions 14, 14 integrally formed outside the lower end thereof. The distance L ₂ (FIG. 1) between the outer ends of the horizontal guide portions 14 is set to a required length (for example, 20 mm) which is considerably larger than the width (for example, 10 mm) of the normal joint c.

The finishing nozzle a having the above configuration, the discharge port d ₁ of the joint material filling cartridges d used was charged in a joint fillers refill caulking gun or the required cartridge loading gun replenish the joint material after each use The joint material 15 is mounted by screwing (FIG. 5), and is used to inject the joint material 15 into the joint c and level the finish as follows.

The joint c forming a concave groove (or V groove) is
According to customary pretreatment, cleaning is performed using a brush or the like. Thereafter, a backup material 16 is laid on the bottom and a required primer is applied thereto, and masking tapes 17 and 17 are applied to the outer sides of the right and left sides of the joint c.
Paste.

Then, the bottom opening 10 of the finishing opening 2 of the finishing nozzle a is made to coincide with the joint c, and the horizontal guide portions 14, 14 are pasted on the outer left and right sides of the joint c, specifically, there. In a state in which the caulking gun or the cartridge d is in contact with the masking tapes 17 and 17, the caulking gun or the cartridge d is supported diagonally by hand as shown in FIG.

In the above, the horizontal guide portions 14, 14
Is can be used while the original width L ₂ is, of course, further, outside the joint c, in particular against the left, right sides edges outside of the space, both or either of the whole of the guide portion 14, 14 Alternatively, a part thereof can be appropriately cut off and used. That is, when the space on the left and right outside of the joint c is narrow, both the horizontal guide portions 14 are cut off to have a required width. When a wall or the like is present on one side of the joint c and there is no space, the horizontal guide portion 14 on one side located on the wall side may be cut off to a required width.

As described above, the finishing port 2 is opposed to the joint c, and the finishing port 2 is positively pressed against the joint with a required pressing force to support the operation of the caulking gun or the cartridge d. By operating a lever (not shown), the finishing opening 2 is pulled forward along the joint c, that is, in the direction of the arrow 18 in FIG.

As a result, the joint material 15 in the caulking gun or the cartridge d is injected and filled into the joint c from the bottom opening 10 through the passage 3 of the mounting tubular portion 1 and the finish port 2. Joint material 1 raised to c
5 is pressed and roughened by the front edge portion 11, and the surface of the roughened joint material 15 is subsequently finished and smoothed by the finish smoothing portion 13. The joint filling and the leveling work of the joint material 15 are continued, and the masking tapes 17 are peeled off to complete joint work.

By the way, the joint c is not always a continuous flat surface as shown in FIG. This is because, as shown in FIG. 6, the beginning and end of a series of joints c are usually closed by a vertical surface 19 such as a wall, a beam or a column orthogonal to the joint c. c forms a right angle corner. Also, the corrugations and the ridges 20 on the surfaces of the panels or tiles arranged adjacently on the left and right sides with the joints c formed at each end face, and the recesses formed on the adjacent portions of these panels or tiles, etc.
It forms an irregular corner on its own surface.

The finishing leveling unit 13 of the finishing nozzle a of the invention will be set formed by the lower end surface 12 ₁ of the lower end surface ₇₁ and the sharp leading edge 12 of the protruding wall 7 of the finished opening 2, In the above-mentioned corner empty space or irregular corner, by raising the front side of the finishing nozzle a, the sharp leading edge 12 is formed.
It is possible to work exactly along the bent surface of the corner or the corner, and therefore, the joint material surface at the corner or the corner exactly conforms to the shape of the corner. It can be finished in a beautiful state (FIG. 6).

Next, the joint c is injected and filled with the joint material 15 as described above.
The joint material 15 injected and filled into the joint c is formed by the operation of the operation lever described above. There may be a state in which the swelling portion rises toward the front side from the finishing opening 2.

In particular, when the joint c itself has an uneven corner portion on its surface as described above, or when the user is not familiar with the use of the finishing nozzle a of the present invention, the finishing of the present invention is performed. In some cases, it is good to roughly perform the injection filling and finishing leveling of the joint material 15 by the nozzle a at the first time, and then to perform the refilling filling and final finish leveling at the next time. May rise to the front side of the finish opening 2 (see FIG. 7).

[0027] However, the lower end surface 8 ₁ of thick-walled 8 forming the finishing opening 2 of the finishing nozzle a of the present invention, under the lower end face 7 ₁ and the right and left sides of the thin walls 9, 9 of the bulging walls 7 End face 9
_1, 9 ₁ from being formed in the upper position, thus, since the front side of the bottom opening 10 is formed a receiving port b to open toward the outside, as described above, the front side of the finishing opening 2 The joint material 15 which is raised at the joint c is received by the finishing port 2 from the receiving port b, and the bottom opening 10 is formed.
, And is again introduced into the joint c, and the surface is finished at the finish leveling section 13 (FIG. 7).

In this case, whether or not a new joint material 15 is to be replenished from the caulking gun or the cartridge d by operating the operation lever, and the amount of replenishment, etc. are determined by the finishing port 2.
The presence or absence and the amount of the joint material 15 which is swelling at the joint c on the near side of the above can be determined appropriately by visual observation.

[0029] If the lower end surface 8 ₁ of thick-walled 8 forming the finishing opening 2 of the finishing nozzle a is, the lower end face 9 ₁ of the lower end surface ₇₁ and the left and right sides of the thin walls 9, 9 of the protruding wall 7, 9 there ₁ in the same plane, when not formed a receiving opening b in front of the bottom opening 10, as shown in FIG. 8, joint fillers are raised from the finishing opening 2 on the front side of the joint c 15 is thick wall 8
The lower end 8 ₂ by being gathered in front of, nor a though its amount is increased, it is intended that there is inconvenience that would may spread to the left and right outer side of the joint c.

In the above description, the finishing nozzle a is integrally molded of an elastic material, the base 5 is fitted inside the mounting tubular portion 1, and the curved front end 6 of the core plate 6 extending from the base 5.
₁ is buried approximately at the center of the thickness of the finishing port 2, more specifically, at the approximate center of the thickness of the bulging wall 7 that is continuous with the lower front side of the mounting tubular section 1. The portion 2 is positively and appropriately pressed against the joint side with a required pressing force as described above, that is, the peripheral surface surrounding the bottom opening 10 of the finish opening 2 is fitted to the outer left and right peripheral surfaces of the joint c. While doing so, a series of operations of injection filling and finish leveling can be performed smoothly.

In other words, although the finishing nozzle 2 is made of an elastic material, it is reinforced by the base 5 and its core plate 6.
There is no such thing as the whole waist being weakly collapsed. Also,
Since it is made of an elastic material, it does not have a drawback that it is difficult to fit the outer sides of the right and left sides of the joint c unlike a case where the joint is made of a hard material such as a metal. However, this does not mean that the finishing nozzle a of the present invention is not suitable if it is made of a metal material.

[0032]

As is clear from the above description,
According to the present invention, the following effects can be obtained. The finishing nozzle of the present invention is such that a base is fitted to the inside of a mounting tubular part integrally formed of an elastic material, and a core plate extending from the base or a curved front end thereof is positioned substantially at the center of the thickness of the finishing mouth. Because it is buried, the finishing opening is positively and appropriately pressed against the joint with the required pressing force, that is, the peripheral surface surrounding the bottom opening of the finishing opening is fitted to the outer left and right sides of the joint While doing so, a series of operations of injection filling and finish leveling can be performed smoothly. The front side edge surface of the bottom opening is a finishing leveling portion, and the finishing opening portion has a receiving port for receiving the joint material raised at the joint continuously formed at the bottom opening, so that the filling is raised at the joint. The joint material can be once received in the finishing opening from the receiving inlet, introduced again into the joint via the bottom opening, and the surface can be finished in the finishing leveling part. When the finishing opening protrudes and forms a sharp front edge having a triangular cross section at the front side of the bottom opening, and forms a finishing leveling portion with the lower end surface of the sharp front edge and the front side peripheral surface of the bottom opening, a normal Of course, the joint surface can be easily and reliably finished and leveled, but by raising the front side of the finishing nozzle, the sharp leading edge is aligned exactly with the bent surface of the corner or uneven corner. Work can be performed, and therefore, the surface of the joint material at these corners or corners can be finished and leveled precisely in accordance with the shape of the corners. Providing the rough leveling edge in the bottom opening and at a position facing the above-mentioned leveling section is effective for easily and surely leveling the joint surface. When the horizontal guide portions are integrally formed to extend outside the lower ends on both right and left sides of the finish opening portion, the finish nozzles having the same size can be used for joints having different widths within the range of the horizontal guide portions.
