BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a putty coating machine. More particularly, the present invention relates to a new putty applicator useful in a drywall method using a gypsum board and capable of forming a beautifully finished seam of a board seam and having good workability.

[0002]

2. Description of the Related Art In recent years, gypsum board has been recognized for its excellent properties such as fire resistance, sound insulation, heat insulation, ease of construction, and economy, and has been used for interiors of all types of buildings from houses to skyscrapers. Have been. When gypsum board is used as a base material for interior, the joint processing is performed,
The objectives are: 1) to smooth out gaps and gaps in the seam; 2) to reinforce the seam to prevent cracks; 3) to ensure sound insulation by the seam treatment, And to block smoke. In order to realize such an object, a dry wall method for treating a joint with joint cement, that is, putty has been established. In addition, the procedure and tools for this method have been devised.

In the dry wall method, as shown in FIG. 10, for example, as a joint treatment for a taper board (a) made of a gypsum board, first, a tape (a) made of glass fiber, cloth, paper or the like is first used. Tension, putty (c) is overcoated with a manual tool called flat finisher, and after drying, further putty (d) is similarly overcoated with a flat finisher, and then sanding or sealer coating is applied. Processing is in progress.

[0004] In the joint processing of the cut portion abutting portion of the gypsum board, for example, as shown in FIG. 11, a tape (a) is applied, and putty (o), (f), and (g) are applied by a flat finisher. Apply sequentially. The flat finisher used at this time is, for example, as shown in FIG.
The putty can be adjusted in the container, and usually putty is put in a container (コ) and putty is put on by a push plate (シ) connected to the tip of a long handle (サ). It is extruded from the mouth (g) so that putty can be applied to the joint. In this coating machine, the pressing plate (S)
It can swing back and forth with the rear part of the substantially V-shaped container (U) as a fulcrum.
Is connected between the upper portion of the container and the rear lower portion of the container so that the push plate is always pushed back until it hits a stopper protruding from the side wall of the container. Acting, the long handle is detachably attached to the push plate.

In such a putty applicator known as a flat finisher, first, the putty is placed in a container (c).
After that, hold the long handle (sa) by hand and press the container (co) against the joint groove of the gypsum board, and push it up and down or left and right (for walls) or front and back, left and right (ceiling) In the case of), at that time, press the push plate (S) with a long handle (S) against the action of the spring (S), and push the plate (S)
Swing toward the front wall of the container (U),
The putty in the container is pushed out from the putty application port (g).

[0006]

However, in the case of the conventional putty coater, although it is beneficial for improving the construction efficiency of the dry wall method, the leveling performance of the putty putty is not satisfactory. After the application of the putty, it has been necessary to smooth it out manually with a putty vera or the like.

In order to improve such a drawback, it is conceivable to mount a blade in front of the putty coating port (g) and perform a leveling operation together with coating, but it is not sufficient to simply mount the blade. On the contrary, there is a problem that the joint processing tends to be incomplete. This was due to the problem that the blade could not sufficiently follow the filling of the seam with the putty. In particular, if the step of the seam is 0.5 mm or more, it is difficult to follow even if a blade is attached to the conventional putty coater as well as the conventional putty coater, and a beautiful finish is not obtained.

In addition, in the case of the conventional coating machine, it is difficult to change the width of the putty, and there is a difficulty in accurately performing the required putty application, and the drawback of using a large amount of putty cannot be avoided. . The present invention has been made in view of the circumstances described above, and eliminates the drawbacks of the putty coating machine in the conventional dry wall method, and allows the required width of the putty coating even if the step at the seam portion of the gypsum board is large. It is an object of the present invention to provide a new and improved putty applicator that can perform appropriate putty application.

[0013]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a putty coating machine according to the present invention. 1 to 4 show an example of a putty coating machine according to the present invention.
For example, as in this example, the putty applicator (1) has a putty container section (2), and the putty container section (2) pushes putty on the front front portion thereof as illustrated in FIG. A putty application port (3) for taking out is provided, and a putty blade (4) for leveling the putty is provided in front of the putty application port (3). The putty blade (4) is provided with a bulge adjusting screw mechanism (5) for pressing the bulge to bulge forward.

As shown in FIGS. 2 and 3, a push plate (6) is arranged at the opening on the rear surface of the container (2), and is swingable by a fulcrum at the rear of the container. A pair of return springs (7) shown in FIG. 3 are connected between the front of the push plate (6) and the rear of the container (2), and the push plate (6) is connected to the upper portion of the front wall of the container (2). , So that it always pushes backwards until it hits a screw-shaped stopper (9) which is provided so as to be rotatable left and right.

On both side walls (8) of the container part (2), a substantially U-shaped finger handle (10) is fixed so as to be attachable and detachable by screws (11). (10) and (12) are attached to the bracket (13) connected to the push plate (6) so as to face the finger handle (10). The finger handles (10) and (12) allow the putty to be pushed out of the putty application port (3) by the manual swinging of the push plate (6).

The bracket (13) has a screw (1).
4) It is made detachable to the push plate (6) by, for example,
Remove the bracket (13) and remove the handle (10) (1
Instead of the operation in 2), the tip of the long handle may be connected to the push plate so that the operation can be performed by this handle. Further, a wheel (15) is attached to the guide bar at the rear of the front surface of the container (2), so that the guide bar is freely rotatable to facilitate movement of the container (2).

As described above, the putty blade (4) is swellable by the swelling adjusting screw mechanism (5), but in the example shown in FIGS. 2 and 3, the screw mechanism (5) is used.
Is disposed substantially at the center of the putty blade (4), and both sides of the putty blade (4) are fixed to the container (2) by screws (16). The putty blade (4) will be further described. For example, as shown in FIG. 4, when the dial (51) is turned in the direction A, the double nut (52) rotates, and the double nut (52) is put on the putty blade. (4) is pressed to bulge forward. Then, as described above, the putty blade (4) is pushed out in the front B direction and bulges out at the substantially central portion, while both sides fixed to the container (2) by the screw (16) remain as it is.
A slight gap (t) will result. Then, in this portion, the amount of the putty can be increased. Therefore, for example, even if the step of the seam of the gypsum board is large, the gap (t) formed by the bulging of the putty blade (4) facilitates the following of the putty application to the large step, and is flat and beautiful. Joint processing is enabled.

Of course, the dial (51) is not located outside the putty blade (4), but between the container part (2) and the putty blade (4) as illustrated in FIGS. You may. In this example, as shown in FIG.
For example, when the dial (51) is rotated in the direction A, the screw (53) inserted into the internal thread of the container (2) is rotated, and the dial (51) moves the putty blade (4) forward B.
Extrude in the direction to bulge. Then, the putty blade (4) bends at a substantially central portion in a bow-like manner, and a gap (t) is generated. This gap (t) adjusts the amount of putty applied, and makes the leveling by the putty blade (4) appropriate.

In any of the arrangements, the amount of the putty applied can be easily adjusted by the swelling of the putty blade (4). Further, the width of the putty coating can be easily adjusted in the present invention. This is because, for example, as shown in FIG.
As for the putty application port (3), the size of the opening is changed by simply screwing the various opening plate bodies (31) to the container part (2) with the metal fittings (32). This is because 3) can be configured. It is preferable that the putty blade (4) be wider at both left and right ends thereof than the entire width of the container (2). This makes the leveling action by the putty coating better.

The opening plate (31) and the metal fitting (32) can have a simple shape and a mounting structure as exemplified in FIG. When the opening plate (31) is attached, if the opening width is small, the flow of the putty in the horizontal direction is unavoidable, so the flow preventing plate (33) is attached as shown in FIG. You may do so.

Corresponding to or independent of such adjustment of the width of the putty coating port (3), the width adjustment of the leveling action of the putty blade (4) is facilitated. For example, as illustrated in FIG. 9, the putty blade (4)
The swelling adjustment screw mechanism (5) can be arranged at a plurality of locations. As shown in FIG. 9, in addition to the fixing by the fixing screws (16) on both sides, the wide blade (4) has bulging adjusting screw mechanisms (5a), (5b), (5) at three places, for example.
c) can be arranged and these can be adjusted simultaneously or separately as required. Then, swelling at only one location is also possible, and it is possible to apply putty only to a required width (W ₁ ). Of course, a wider width (W ₂ )
Width adjustment is also possible.

In the above example, the injection of the putty is not described, but the pressing plate (6) may be opened and put in the container (2), or the putty application port (3) or the opening thereof may be opened. You may make it put in a container in a state. And
An example of the use of the handles (10) and (12) has been shown. When applying with a long handle, it is convenient for seam treatment of a base material for a large wall or ceiling with a height of 3 m, but the height is 4 to At 5 m, scaffolding is necessary because it is difficult to handle, but on the scaffolding, it is difficult to flatten and it is difficult to smooth the painted surface of putty, and also in narrow places such as toilets and washrooms,
In the case of a window frame or a tanning, there is a drawback that a long handle is in the way and workability is poor, but putty coating without such inconvenience becomes possible.

Of course, the present invention is not limited to the above example, and various other embodiments are possible.

[0024]

According to the present invention, as described in detail above, even if the step of the seam of the gypsum board is large, it is easy to follow the putty application and a smooth and beautiful finished state can be obtained. Further, the application width can be easily adjusted, and appropriate joint treatment can be performed with a small amount of putty.
