“Prior Art and Its Problems” Generally, when glass is bonded to each other at a construction site, a caulking agent as a filler as shown by reference numeral 1 in FIGS. 4 (A) and 4 (B) is used. Has been done. The caulking agent 1 is used not only for bonding the glasses 2 and 2 as described above, but also for bonding between the sash outer frame and the wall of the building.

By the way, after the caulking agent 1 is filled,
As time passes, the solvent contained therein volatilizes and the volume shrinks as indicated by the symbol M in FIG. 4 (B). As a result, for example, a recessed portion is formed in the caulking agent, resulting in inferior appearance and weakened strength of the portion.

On the other hand, as a conventional caulking spatula or a jig similar thereto, the following are known.

That is, the bottom surface of the spatula is provided with a rounded surface portion, and the rounded surface portion is pressed against the inner side surface of the corner portion of the window frame or the like to form the same recess on the upper surface of the caulking agent (Shokai Sho 60-1833).
(See Japanese Patent Laid-Open Publication No. 2004-107242), an insertion hole for inserting a caulking agent filling nozzle is provided in the jig body between a pair of introduction pieces inserted inside the joint portion filled with the caulking agent, and the jig body In order to prevent the caulking agent protruding from the joint near the joint from sticking to the surface of the exterior material, a spatula piece is provided at the rear end to cut off the caulking agent. There is a method in which a masking agent is applied to the exterior material (see JP-A-61-25669).

However, in the above technique, the left and right exterior materials are intended to be arranged with a 90-degree included angle, or to be arranged in a plane, for example, with an opening angle of 270 degrees. It was impossible to finish the joints between the exterior materials.

The present invention has been made in view of the above circumstances, and the filling work of the caulking agent in anticipation of the volume reduction is easily performed to prevent the formation of depressions in the caulking agent to improve the appearance. And to obtain a caulking spatula capable of holding the caulking agent at a constant strength.

In the present invention, a notch is provided in a plate-like spatula body used for adhering corners of plate-like bodies to each other, and each notch is formed in the end face of the plate-like body. While touching one side of
The first side and the second side are linear and are orthogonal to each other, and the third side is formed by curving in an arc shape and continuously connects the first side and the second side. .

[Operation] According to the present invention, for example, a pair of plate members such as glass are prepared, and then corners are formed with the end faces of the plate members exposed, and further, both end faces of the plate member are formed. When the portion is continuously filled with a caulking agent, the notches are arranged so as to sandwich the corners of the plate-like body, and the spatula body is slightly inclined with respect to the filling direction of the caulking agent.
In this state, by sliding the spatula body along the caulking agent filling direction, the caulking agent can be leveled in order.

Further, in this case, since the cutout portions are each formed in a linear shape and are configured by the first side and the second side provided so as to be orthogonal to each other, the spatula body is slid. After caulking, the caulking agent is
Depending on the angle formed by the side and the second side, and depending on the inclination angle of the spatula body described above, the central portion thereof can be made to have a raised shape.

[Embodiment] An embodiment of the present invention will be described with reference to FIGS. 1 to 3B.

As shown in FIG. 1, each of the cutouts 4 is formed in a straight line shape, and is curved in an arc shape with a first side 4A and a second side 4B which are formed at substantially right angles to each other. It is composed of a third side 4C which is formed and continuously connects the first side 4A and the second side 4B. Then, among these first side 4A to third side 4C, the third side 4C is for contacting with a caulking agent (reference numeral 8 will be described later), and the first side 4A and the second side 4B. The term "a part" means that the part comes into contact with the caulking agent and also comes into contact with one side of the end face of the glass (described later with reference numerals 6A and 6B). That is, the corners formed by the pair of glasses are sandwiched by the notches 4 (described later).

Next, the usage and operation of the caulking spatula constructed as described above will be described with reference to FIGS. 2 and 3 (A) and (B).
Will be described in the order of the steps with reference to.

(1) First, a pair of glasses (plate-like bodies) as shown by reference numeral 6.6 in FIG. 2 are prepared, and the glass surfaces 6A and 6B are exposed to each other with the end surfaces 6A and 6B exposed. Arrange them at right angles to form corners. And in this state,
Masking tapes 7 and 7 are attached on the glass 6 and 6 along the end surfaces 6A and 6B.
・ The caulking agent 8 described later by 7 is the glass end surface 6A
Prevent it from adhering to 6B.

(2) The caulking agent 8 is continuously filled between the both end surfaces 6A and 6B of the glass 6. The caulking agent 8 used here may be one containing a silicone resin.

(3) While bringing the notch 4 into contact with the caulking agent 8 so as to sandwich the corners of the glass 6 and 6, the spatula body 3 is
The caulking agent 8 is slightly inclined with respect to the filling direction of the caulking agent 8 (the direction indicated by the arrow AB in FIG. 2), and in this state, the spatula body 3 is moved to the caulking agent 8 direction. Slide in the direction of arrow AB along the filling direction. The slide is performed by the operator holding the back of the spatula main body 3 by hand, as indicated by the chain double-dashed line.

The back surface 3A of the spatula body 3 is pressed against the caulking agent 8 from above by the slide of the spatula body 3 in the direction of the arrow A-B, and the spatula body 3 is formed at the peripheral portion of the spatula body 3. The notch 4 raises the central portion of the surface of the leveled caulking agent 8.

That is, by arranging the notches 4 so as to sandwich the corners of the glasses 6 and 6, and by inclining the spatula body 3 at an angle indicated by θ with respect to the direction of arrow AB, and sliding it, As shown in FIG. 3 (A), the shape of the caulking agent after sliding can be a shape in which the central portion is raised according to the arc shape of the cutout portion 4.

Although the spatula body 3 has a flat shape, it is not limited to this and may have a curved shape with the arrow AB of FIG. 1 as the center of the arc.

Further, although the angle formed by the glasses 6 and 6 is a right angle, the angle is not necessarily limited to this angle.

Further, the hole shown by reference numeral 10 in FIGS. 1 and 2 is for inserting a rod-shaped protrusion, and by engaging with this protrusion, for example, it can be hung and stored on the wall in the warehouse. It has become.

[Advantage of Invention] As described in detail above, according to the present invention, since the notch portion is provided in the plate-like spatula body, the notch portion is arranged so as to sandwich the corner of the plate-like body, and the spatula is provided. The caulking agent can be leveled in order by making the main body slightly inclined with respect to the caulking agent filling direction and further sliding the spatula main body along the caulking agent filling direction in this state.

Further, in this case, since the cutout portions are each formed in a linear shape and are configured by the first side and the second side provided so as to be orthogonal to each other, the spatula body is slid. After caulking, the caulking agent is
Depending on the angle formed by the side and the second side, and depending on the inclination angle of the spatula body described above, the central portion thereof can be made to have a raised shape. Then, by forming the central portion of the caulking agent in such a raised shape, even when the caulking agent contracts with the passage of time, it is prevented that the surface of the caulking agent is depressed. As a result, it is possible to prevent the caulking agent from forming a weak portion and to prevent the appearance from being deteriorated.

Further, the plate-like spatula body used for bonding the corners of the plate-like bodies is provided with a notch portion, and each of the notch portions is in contact with one side of the end face of the plate-like body and is orthogonal to each other. Since the spatula body is slid along one side of the end surface of the plate-shaped body, the first side and the second side have end surfaces of the plate-shaped body. Slides against one side of the plate, which prevents the caulking agent used to bond the corners from protruding from the end face of the plate.

Further, since the cutout is curved in an arc shape and has a third side that continuously connects the first side and the second side, the shape of the caulking agent after sliding the cutout Can have a raised shape in the center. Therefore, after the caulking agent contracts, the surface of the caulking agent can be smoothed, and the caulking agent surface can be prevented from being dented, which can prevent the caulking agent from having a weak portion. Also, the appearance of the adhesive portion of the corner can be improved.
