Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for injecting a desired joint material into joints between panels forming a curtain wall, joints between tiles, joints around a sash, and other joints. The present invention relates to an improvement of a joint material filling and finishing nozzle.

[0002]

2. Description of the Related Art Conventionally, in order to inject and fill a joint material into a joint, a jointed material-filled cartridge is loaded into a required cartridge loading gun, or a joint material replenishing type caulking gun which replenishes the joint material each time it is used. It is done by operating each lever.

At the front end of the joint material-filled cartridge or joint material replenishing type caulking gun, a required nozzle is integrally or detachably provided, and the joint material is injected and filled into the joint through this nozzle. After that, a jointing spatula or the like made of metal such as stainless steel or steel is used to scrape off the joint material that has leached out and to finish the surface flat.

[0004]

The direct pouring and filling from the nozzle is apt to cause an excess or deficiency in the pouring amount, especially by an unskilled worker, and therefore scratching of the protruding joint material with a finishing spatula or the like is also necessary. Not only is there a drawback that the removal and surface finishing are troublesome, but there is also the drawback that the injection work and the finishing work must be performed separately in the first place,
Moreover, both the pouring work and the finishing work require considerable skill.

[0005] Therefore, the applicant of the present invention has conducted earnest researches so that the injection and filling of the joint material and the surface finishing can be performed at the same time, and even for a beginner, the joint material can be easily, surely and cleanly formed. We are currently developing and proposing various joint material filling and finishing nozzles, which are composed of a mounting cylindrical portion and a finishing mouth portion, which are mounted on the outlet of a refillable caulking gun or the outlet of a cartridge that has been filled with joint material.

The present invention corresponds to a joint material filling finishing nozzle which is further improved. The main object of the present invention is to perform the treatment of the start end and the end of the joint in a good appearance, and to form the joint and to prevent the unevenness of the panel surface or the tile surface itself which are arranged in the left and right adjacent rows, A simple and reliable construction of joint finish along unevenness formed on each adjacent portion of these panels or tiles. Another main object of the present invention is to fill and fill joints with the joint material replenishing type caulking gun or the jointing material filling cartridge by operating the operating lever of the jointing material filling lever. The purpose is to automatically introduce the amount of material that has risen more than necessary into the joints again and eliminate the appearance of the material that spills out of the joints.

[0012]

EXAMPLE This finishing nozzle a comprises a mounting cylindrical portion 1 and a finishing port portion 2 which are integrally molded of an elastic material such as various kinds of rubber or synthetic resin, and a series of passages 3 are formed therein. . On the inner side of the mounting cylindrical portion 1, a female thread 4
A core plate 6 into which a cap 5 formed by engraving is fitted and whose curved tip 6 ₁ extends within the wall thickness of the finishing port 2 more specifically, the core plate 6 extending from the base 5 The bulging wall 7 that is continuous to the lower front side is embedded in the center of the wall thickness.

In the finishing port 2, the bulging wall 7, the lower thick wall 8 and the lower left and right thin walls 9 _, 9 have their lower end surfaces 7 ₁ , 8 ₁ , 9 ₁ , A rectangular bottom opening 10 continuous with the passage 3 is surrounded by 9 ₁ , and a lower end surface 7 ₁ of the bulging portion 7 which is a front side edge surface of the bottom opening 10 is used as a finish leveling portion 13. Three sides surrounding the bottom opening 10, that is, lower end surfaces 7 ₁ , 9 ₁ , and 9 ₁ forming the front side and the left and right sides are formed in the same plane. On the other hand, the other one of the bottom surface openings 10, that is, the lower end surface 8 ₁ forming the front side is the lower end surface 7 ₁ ,
9 ₁ and 9 ₁ are formed at a position higher than that of the bottom opening 10. Therefore, the front side of the bottom opening 10 has an inlet b that opens outward.
In the present invention, one point is to be provided with the receiving port b.

The distance L ₁ (FIG. 1) between the left and right thin walls 9 _, 9 that is the width of the finishing opening 2 is larger than the normal width of the joint c (for example, 10 mm) (for example, 15 mm). The lower end faces 9 ₁ , 9 ₁ of the thin walls 9 _, 9 are of a length such that they can contact the outer side faces on both the left and right sides of the joint c. Further, the width of the bottom opening 10 is set narrower than the normal width of the joint c (for example, 10 mm),
The joint material discharged from the bottom opening 10 is accurately injected into the joint c.

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

The bulging wall 7 is formed with a sharp front edge 12 having a triangular cross section on 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, the pointed front edge 12 formed 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 on the outer sides of the lower ends thereof. The distance L2 (FIG. 1) between the outer ends of the horizontal guide portions 14 and 14 is set to a required length (for example, 20 mm), which is considerably wider than the width of the common joint c (for example, 10 mm).

The finishing nozzle a having the above-mentioned structure is installed in a jointing material replenishing type caulking gun for replenishing the jointing material each time it is used, or in a discharge port d ₁ of a jointing material-filled cartridge d to be used by being mounted in a required cartridge loading gun. It is mounted by screwing (FIG. 5), and is used for injecting the joint material 15 into the joint c and finishing smoothing as follows.

The joint c having a concave groove shape (or V groove shape) is
It is cleaned with a brush etc. according to the customary pretreatment. After that, a backup material 16 is laid on the bottom portion, a required primer is applied to the backup material 16, and masking tapes 17 and 17 are provided on the outer sides of the left and right edges of the joint c.
Paste.

Then, the bottom opening 10 of the finishing port 2 of the finishing nozzle a is made to coincide with the joint c, and the horizontal guide portions 14, 14 are attached to the outer side surfaces of the left and right edges of the joint c, specifically, there. While contacting the masking tapes 17 and 17, the caulking gun or the cartridge d is manually supported obliquely as shown in FIG.

In the above, the horizontal guide portions 14, 14
Can be used with the original width L ₂ as it is, but further, according to the space outside the joint c, particularly the space outside the left and right side edges, both or one of the guide portions 14, 14 can be used. Alternatively, a part of them can be cut off and used as appropriate. That is, when the space on the left and right sides of the joint c is small, both the horizontal guide portions 14 and 14 are used by cutting off the required width. When there is a space or the like 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 used by cutting off the required width.

As described above, the finishing opening 2 is opposed to the joint c, and the finishing opening 2 is positively pressed and supported to the joint side with a required pressing force to operate the cartridge or caulking gun d. By operating a lever (not shown), the finish material 2 is pulled out along the joint c while pushing the joint material 15 forward, that is, in the direction of arrow 18 in FIG.

As a result, the joint material 15 in the cartridge or the caulking gun d is injected and filled into the joint c from the bottom opening 10 through the passage 3 of the mounting cylindrical portion 1 and the finishing opening 2. Joint material 1 raised on c
5 is pressed by the front edge portion 11 and is roughly leveled, and the surface of the roughened joint material 15 is subsequently finished and leveled by the finish leveling section 13. The injection and filling of the joint material 15 and the leveling operation thereof are continued, and the joint construction is completed by peeling and removing the masking tapes 17, 17.

By the way, the joint c does not always have a continuous flat surface as shown in FIG. This is because, as shown in FIG. 6, the start end and the end of a series of joints c are normally closed by a vertical surface 19 such as a wall, a beam or a column which is orthogonal to the joint c, and the vertical surface 19 and the joints are closed. A corner portion forming a right angle with c is formed. In addition, the corrugation on the surface of the panel or the surface of the tiles that are adjacently arranged in a row on the left and right to form the joint c at each end face, the ridges 20, and the recesses or the like generated in each adjacent portion of these panels or tiles are the joints c.
It forms a non-cornered portion on the surface of itself.

The finishing leveling portion 13 of the finishing nozzle a according to the present invention is formed by the lower end surface 7 ₁ of the bulging wall 7 of the finishing opening portion 2 and the lower end surface 12 ₁ of the sharp front edge 12. In the above-mentioned corner space or uneven corner portion, by raising the front side of the finishing nozzle a, the sharp front edge 12 is
It is possible to work along the bent surface of the above-mentioned corner or uneven corner exactly, and therefore, the joint material surface at these corners or uneven corners should be exactly along the shape of the corner. It can be finished and smoothed in a clean state (Fig. 6).

Next, the filling and filling of the joint material 15 into the joint c is performed by the caulking gun or the cartridge d as described above.
It is carried out by operating the operation lever of No. 1, but the joint material 15 injected and filled into the joint c is determined by the relation between the pushing pressure and amount, the speed of pulling the finishing opening 2 along the joint c, and the like. There may be a state in which it rises to the front side from the finishing opening 2.

Further, in particular, when the joint c itself has an uneven angle portion on the surface as described above, or when the use of the finishing nozzle a of the present invention is not familiar, the finishing of the present invention is performed. It is sometimes good to perform the filling and filling and finishing smoothing of the joint material 15 with the nozzle a first roughly and then the supplementary filling and filling and the final finishing smoothing next time. May be raised to the front side of the finishing 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
_Since it is formed at a position higher than ₁ , 9 ₁ and therefore the front side of the bottom opening 10 is formed with an inlet b that opens outward, as described above, the front side of the finishing opening 2 is The joint material 15 that is raised in the joint c is once received from the receiving opening b into the finishing opening 2, and the bottom opening 10
It is again introduced into the joint c via the and is finished by the finish leveling section 13 (FIG. 7).

In this case, whether or not the joint lever 15 is replenished from the caulking gun or the cartridge d by operating the operating lever, and the replenishment amount, etc., are determined by the finishing port 2.
The presence or absence and the amount of the joint material 15 which is raised in the joint c on the front side can be visually determined and appropriately determined.

[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 a thick wall 8
This is disadvantageous in that the lower end portion 8 ₂ of the joint c gathers it closer to the front side, and as the amount thereof increases, it spreads to the left and right of the joint c.

In the above, 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 tip 6 of the core plate 6 extending from the base 5 is extended.
_{Since 1} is embedded almost at the center of the wall thickness of the finishing opening 2, more specifically, the wall thickness of the bulging wall 7 continuous to the lower front side of the mounting tubular portion 1, the finishing opening made of an elastic material is used. As described above, the portion 2 is positively and moderately pressed against the joint side with a required pressing force, that is, the edge surface surrounding the bottom opening 10 of the finishing opening portion 2 is fitted to the left and right side edge outer surfaces of the joint c. While doing so, it is possible to smoothly perform a series of operations of injection filling and finish leveling.

In other words, although the finishing nozzle 2 is made of an elastic material, it is reinforced by the die 5 and its core plate 6,
There is no such thing as the entire waist being weakly crushed. Also,
Since it is made of an elastic material, it does not have the drawback that it is difficult to fit to the outer surfaces of the left and right side edges of the joint c as in the case of being made of a hard material such as metal. It should be noted that the finishing nozzle a of the present invention is not unsuitable if it is made of a metal material.

[0032]

As is clear from the above description,
The present invention has the following effects. The front side edge surface of the bottom opening is a finish leveling part, and
In the finishing mouth portion, since the receiving opening for receiving the joint material raised in the joint is continuously formed in the bottom opening, the joint material raised in the joint is once received from the receiving mouth to the finishing mouth portion, It can be reintroduced into the joint via the bottom opening and surface-finished at the finish leveling section. When the finish mouth portion projects a sharp front edge having a triangular cross section on the front side of the bottom opening, and a finish leveling portion is formed by the lower end surface of the sharp front edge and the front side edge surface of the bottom opening, a normal finish portion is formed. Not only can you finish the joint surface easily and reliably, but by raising the front side of the finishing nozzle, the sharp front edge can be made to follow the bent surface of the corner or uneven corner exactly. Therefore, the surface of the jointing material at the corners or the non-cornered corners can be finished and smoothed in a clean state that exactly follows the shape of the corners. It is effective to simply and surely finish the joint surface easily and surely by vertically arranging the roughening edge at a position in the opening of the bottom face and facing the finish smoothing portion. When the horizontal guides are integrally extended and formed on the outside of the lower ends on the left and right sides of the finishing opening, finishing nozzles of the same size
It can be used for joints with different widths within the range of the horizontal guide. The finish nozzle of the present invention is fitted with a mouthpiece inside a mounting cylindrical portion integrally molded with an elastic material, and a core plate extending from the mouthpiece or a curved tip portion thereof is provided substantially at the center of the wall thickness of the finish mouth portion. By embedding it, the finishing opening is positively and moderately pressed against the joint side with a required pressing force, that is, the edge surface that surrounds the bottom opening of the finishing opening is on the outer surface of both left and right sides of the joint. While fitting, it is possible to smoothly perform a series of work of injection filling and finish leveling.
