Abstract

PURPOSE:To insert a joint material to a joint having a comparatively large joint width nearly to a fixed depth and nearly in parallel by pressing the joint material by three pressing discs. CONSTITUTION:A center pressing disc 2 about the center of which is made of an elastic material is nipped by two side edge pressing discs 3, 3, and a rotating shaft 4 is passed through nearly the centers of the discs 2, 3. A handle 5 is mounted on the handle 5, and the respective pressing discs 2, 3 are rotatably mounted on the handle 5. The distance from one side edge pressing disc 3 to the other side edge pressing disc 3 is smaller than a joint width. Since the distance from one side edge pressing disc 3 to the other side edge pressing disc 3 is smaller than the joint width, thus, a joint material 7 can be pushed into a joint by the pressing discs 2, 3. The joint material inserting jig is advanced along the joint in this state. By observing the advancing state of the side edge pressing discs 3, the joint material 7 can be inserted to a fixed depth and nearly in parallel.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint material insertion jig used for inserting a joint material into a joint between an outer wall panel and an adjacent outer wall panel.

In particular, the present invention relates to a joint material inserting jig suitable for inserting joint material into joints having a relatively large joint width.

[0003]

2. Description of the Related Art In the past, there were many so-called wet construction methods in which the outer wall of a house was painted with soil, but recently, in order to shorten the construction period of a residential building, an outer wall panel was manufactured in a factory and this outer wall panel was used. The so-called dry method of attaching to the wall of a house is increasing.

When this outer wall panel is attached to the wall of a house, joints are inevitably formed between the outer wall panel and the adjacent outer wall panel. Therefore, as described in Japanese Patent Application Laid-Open No. 61-98840, so that rainwater does not enter from this joint,
A joint material made of an elastic material such as rubber is inserted in this joint.

In order to insert the joint material into the joint between the outer wall panel and the adjacent outer wall panel, the joint material has conventionally been pressed with a hand or a spatula. In order to prevent rainwater from entering between the joints, the joint material is made wider than the normal joint, and this joint material is forcefully inserted into the joint, and the joint material is elastically attached to the side end surface of the outer wall panel. It is pressed against, making this part watertight.

Therefore, since a joint material having a width wider than that of the joint is inserted into this joint with force, the fingertips and arms are tired and it is difficult to continue the work for a long time. Recently, in order to simplify this operation, as described in Japanese Patent Application Laid-Open No. 2-99155, a joint material is inserted into a joint using a roller.

An example of a joint material insertion jig for inserting joint material using this roller will be described with reference to FIGS. 5 to 7. A rotary shaft 102 is attached to the disk 101 at substantially the center thereof. A handle 103 is attached to the rotating shaft 102, and the disc 101 is rotatably attached to the handle 103.

This joint material insertion jig is used in such a manner that the band-shaped joint material 104 is pressed with one hand along the joint 105, and the grip 103 is held with the other one hand, and the disc 101 is used as the joint material 10.
4 from above, the circular portion of the disc 101 is pushed into the joint 105 together with the joint material 104, and in this state, the roller is advanced along the joint, and the joint material 104 is connected to the joint 105.
To be inserted inside.

[0009]

However, in such a joint material insertion jig, if the disc 101 pushes the central portion in the width direction of the strip-shaped joint material 104, the joint material 104 can be inserted substantially horizontally into the joint 105. Then, as shown in FIG. 6 and FIG. 7, the disc 101 moves toward the edge of the joint 105, and the joint material 104 is inserted in a tilted state.
In many cases, the disc 101 cannot be inserted because the disc 101 is inserted between the side wall 4 and the side end surface of the outer wall.

The reason for this is that the joint material 104 is the joint material 1.
The friction between 04 and the edge of the outer wall is large, and it is difficult to uniformly press the edges on both sides of the joint material 104. In particular, there are many problems when the joint material is inserted into a joint having a large joint width.

Therefore, an object of the present invention is to provide a joint material inserting jig which allows the joint material to be easily and almost horizontally inserted into a joint between an outer wall panel and an adjacent outer wall panel. ..

[0012]

The present invention has been made to solve the above problems and to achieve the above objects, and is a joint material for inserting joint material into joints between an outer wall panel and an adjacent outer wall panel. In the insertion jig, a central pressing disk made of an elastic material around the center and two side edge pressing disks of approximately the same size as the central pressing disk sandwich the central pressing disk. The rotating shaft is passed through substantially the center of the center pressing disc and the side edge pressing disc that are superposed, and the handle is attached to the rotating shaft so that each holding disc is rotatably attached to the handle. The distance from one side edge holding disc to the other side edge holding disc is smaller than the width of the joint.

In the present invention, the central pressing disk and 2
A rotating shaft is passed through the center of each side edge holding disc, and a handle is attached to the rotating shaft so that each disc is rotatably attached to the handle. As a method of freely attaching, each pressing disc and the rotary shaft may be rotatably attached, or the rotary shaft and the handle may be rotatably attached. Further, both of them may be rotatably attached.

Further, the central pressing disk used in the present invention is made of an elastic material around the center. That is, this elastic material has only to be provided around the center of the central pressing disc, and it may be entirely made of an elastic material from the center to the surface, or may be provided only near the center. Good. Further, it may be provided around the center with a constant width in the middle part of the radius. Particularly, it is preferable that the central portion of the central pressing disk is made of a circular elastic material.

In the present invention, the two side edge holding discs and the center holding disc are attached to the rotary shaft so that the distance between the two side edge holding discs and the center holding disc can be adjusted. By adjusting this distance to the size of the joint width,
It is convenient because it can be applied to joints of any width.

[0016]

The method of using the joint material inserting jig of the present invention is to attach the outer wall panel to the wall of the house, and then press the joint member between the outer wall panel and the adjacent outer wall panel with one hand,
Hold the handle of the joint material insertion jig with the other hand, and press the joint material strongly from above the joint material with the center pressing disc and the two side edge pressing discs.

Then, since the distance from the side edge pressing disk to the other side edge pressing disk is smaller than the width of the joint, the central pressing disk and the circumferential portions of the two side edge pressing disks form the joint material. While pressing, enter the joint with the joint material.

At this time, since the circumference of the center of the central pressing disk is made of an elastic material, the elastic material is compressed and the central pressing disk is eccentric as shown in FIG. On the other hand, since the side edge holding disc has no elastic material, both side edges of the joint are strongly pressed.

Therefore, the surface of the joint material becomes a curved surface with a slightly raised central portion, and the joint material is inserted into the joint. If the side edge pressing disc is advanced while looking at the side edge pressing disc, both side edges of the joint material are pressed to substantially the same depth by the side edge pressing disc, so that the joint material is not inserted in an inclined state.

When the handle is advanced along the joints in this state, the center pressing disc and the two side edge pressing discs are rotatably attached to the handle, so that these The pressing disc moves forward while rotating along the joint. Then, the central pressing disc and the two side edge pressing discs press the strip-shaped joint material in order with the central portion of the joint material slightly raised.

As described above, since the joint material is pressed into the joint by these three pressing disks, the joint material inserting jig of the present invention can be used for joints having a relatively wide joint width. Again 2
If the distance between the side edge holding disc and the center holding disc can be adjusted, the distance between these discs can be adjusted according to the size of the joint width, so it can be applied to joints of any width. ..

EXAMPLES Next, examples of the present invention will be described. Example 1
1 to 4 show an embodiment of a joint material inserting jig of the present invention. FIG. 1 is a perspective view of the joint material inserting jig, and FIG. 2 is a center pressing disk of the joint material inserting jig shown in FIG. FIG. 3 is a perspective view showing a central pressing disk and a side edge pressing disk showing the order of stacking with the side edge pressing disk, FIG. 3 is a perspective view showing a small state of the joint material insertion jig shown in FIG. It is sectional drawing of the use condition shown in FIG.

In FIGS. 1 to 4, reference numeral 1 denotes a joint material inserting jig, and the joint material inserting jig 1 has a central pressing disc 2 and a side edge pressing circle having substantially the same size as the central pressing disc 2. The plate 3 and the center pressing disc 2 are superposed on each other, and the rotary shaft 4 is rotatably passed through the center of the superposed center pressing disc 2 and the side edge pressing disc 3. A handle 5
Is attached.

At this time, the distance between the two side edge pressing disks 3 and 3 and the central pressing disk 2 may be adjusted.
The central portion of the center pressing disc 2 is made of a circular elastic material 21 made of natural rubber.

Reference numeral 6 is an outer wall panel. Reference numeral 7 is a band-shaped joint material, and this joint material 7 is inserted into the joint between the outer wall panel 6 and the adjacent outer wall panel 6.

Next, a method of using the joint material insertion jig 1 will be described. First, the outer wall panel 6 is attached to the wall of the house, and the band-shaped joint material 7 is pressed with one hand along the joint between the outer wall panel 6 and the adjacent outer wall panel 6.

After that, holding the handle 5 with the other hand from above the joint material 7, the center pressing disk and the two side edge holding disks 3 and 3 are strongly pressed from above the joint material 7, and the joint material 7 is pressed. Hold 7 in the joint.

Then, as shown in FIG. 4, the center holding disc 2 and the two side edge holding discs 3, 3 are separated from each other by one side edge holding plate 3 to the other side edge holding plate 3. Is smaller than the joint width, the central pressing plate 2 and the two side edge pressing discs 3 and 3 enter into the joints, and the central pressing disc 2 and the two side edge pressing discs. The joint material 7 is pushed into the joint by being pressed by the 3 and 3.

At this time, since the periphery of the center of the central pressing disc 2 is made of the elastic material 21, the joint material 7 has a curved surface with a slightly raised central portion as shown in FIG. The side edge portion where the friction between the side end surface and the joint material 7 is large is strongly pressed by the respective side edge pressing disks 3 and 3, and the joint material 7 is inserted into the joint.

As described above, since the side edge portions of the joint material 7 are pressed by the respective side edge pressing disks 3 and 3, the joint material is checked by checking the progress of the side edge pressing disks 3 and 3. It is possible to insert both side edges of 7 at approximately the same depth.

Next, the joint material insertion jig 1 is pushed forward while being pushed. When the insertion depth of the side edge pressing disc 3 is constant, the joint material 7 is inserted at a constant depth.

As described above, the use of the joint material insertion jig of this embodiment is convenient because the joint material can be inserted into the joint at a substantially constant depth and substantially horizontally.

[0033]

In the joint material insertion jig of the present invention, since the distance from one side edge holding disc to the other side edge holding disc is smaller than the joint width, these joint discs joint the joint material. Can be tucked inside.

Further, since the periphery of the center of the center pressing disk is made of an elastic material, when the joint material is pressed, both sides of the joint material are pressed by the side edge pressing disks, and the center portion of the joint material is the center. Although it is pressed by the pressing disk, since the center of the central pressing disk is made of an elastic material, the central part has a curved surface that rises upward, and the joint material is inserted into the joint.

At this time, since both side edges of the joint material are pressed by different side edge holding discs, by checking the progress state of the side edge holding disc, the joint material is made to have a certain depth at the joint. Moreover, the joint material can be inserted almost horizontally.

Further, since the center pressing disc and the two side edge pressing discs are pressed by the three discs, even the joint having a relatively large joint width has the joint material at substantially the same depth and substantially horizontally. Can be inserted into.

If the distance between the two side edge pressing disks and the central pressing disk can be adjusted, it can be used for joints of any width, which is convenient. Thus, the present invention is extremely valuable.
