[0001]

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

[0002]

2. Description of the Related Art As shown in FIG. 10, a nozzle-removable type cartridge already known as this type of joint material filling cartridge closes a front end opening of a cylindrical container body 27 with a front end plate 28 and has a rear end end. A joint material 31 is filled between an aluminum film 30 which is closed by a plate 29 and is stretched in a position close to the inside of the front end plate and the rear end plate 29, and a nozzle provided on the front end plate at the time of joint construction. A sharp member such as a nail is inserted through the cylindrical mouth portion 32 to break through the aluminum film 30, and
The injection nozzle 3 is cut off at a required portion having a diameter corresponding to the tapered width of the injection nozzle separately formed into a tapered blind end shape, and the injection nozzle 3 is cut off.
The entire cartridge in which male and female threads 3 are screwed and attached to the cylindrical mouth is attached to a known filling gun separately prepared for use.

[0003]

That is, in the actual joint construction of the conventional filler-filled cartridge, when the nozzle is attached and detached, it must be screwed together with alternate male and female threads, and the aluminum which is stretched inside the cylindrical container body. There is a drawback that it is necessary to break through the membrane or cut off the injection nozzle at a portion having a diameter matching the joint width, which is troublesome.

Further, the joint material is injected into the joint directly from the injection nozzle, and thereafter, the extruded joint material is scraped off using a metal finishing vera such as stainless steel or steel, and the joint material is scraped off. The disadvantage is that the required finishing must be achieved by leveling the surface. When this is laid, direct injection from the injection nozzle is likely to cause an excess or deficiency in the injection amount, especially when a skilled worker,
Therefore, in addition to the disadvantage that scraping and surface finishing of the protruding joint material by the finishing wrench is troublesome, there is a disadvantage that the injection work and the finishing work must be performed separately in the first place, and furthermore, the injection work is also required. All of the finishing work requires considerable skill.

The main object of the present invention is to immediately inject a joint material without the above-described work of breaking through the aluminum film, cutting off the tip side of the injection nozzle, and screwing together with the female and male threads. Is to do so. Another object of the present invention is to make it possible to finish the surface at the same time as the joint material is injected, and to make it easy and secure for beginners.

As apparent from the above description, the present invention has the following effects. Immediately by pushing the operation lever of the filling gun manually, the jointing material is pushed out without performing screwing work with alternate female and female threads at the time of attaching and detaching the nozzle, breaking through the aluminum film, and cutting off the tip side of the injection nozzle, And just by pulling the filling gun forward along the joints, it is possible to finish and level the joint material sequentially while injecting it into the joints. Can be implemented.

That is, in the actual joint construction in the conventional nozzle-removable type of joint filler-filled cartridge, it is necessary to screw together with alternate female and female threads and cut off the injection nozzle to a portion having a diameter matching the joint width. Work such as pre-piercing the aluminum film stretched inside the cylindrical container with a sharp member such as a nail must be performed, and the surface finish leveling of the injected joint material must be performed separately from the injection work. Although the present invention did not require these operations,
The merits such as improvement of joint construction work efficiency and cost reduction by this are extremely large.
