In the figure, reference numeral 5 indicates a joint rod that has been inserted from the outside into the joint 7 between the outer wall panels 6 and 6 and temporarily attached. The aforementioned pressing protrusion 4 of the tool 1 is applied, and then the tool body 3 is hit with a plastic hammer 8 or the like until the lower surface 2 of the tool body 3 comes into contact with the surfaces of the outer wall panels 6, 6. The joint bar 5 is pushed into the joint 7, whereby the joint bar 5 is installed at a constant depth.

Problems that the invention aims to solve However, with conventional installation tools, only a single pressing protrusion is provided on the tool body, so when trying to change the depth of the joint bar, the pressing protrusions of different heights The problem was that it required multiple installation tools. Another problem is that it is difficult to make delicate adjustments when the joint bar is tilted.

This invention was made in view of the above-mentioned problems, with the purpose of providing a joint bar installation tool that can be used in various situations.

A short pressing protrusion 22, which is oriented in the transverse direction of the tool body 11 and parallel to the reference plane 20, is protruded from the protruding base portion 21.

Operation By selecting the long pressing protrusions 13 and 17 provided in the longitudinal direction of the tool body 11 and having different heights, a joint bar is placed at a depth corresponding to the height of each pressing protrusion 13 and 17. I am now able to stably pay the amount. By using the short pressing protrusion 22 provided on the protruding base 21 at one end of the tool body 11, it is possible to install a joint bar even in a complicated place along a sash, etc., or to finely adjust the inclination of the joint bar. Now I can do things like

Embodiment Hereinafter, an embodiment of this invention will be explained based on the drawings.

FIG. 1 shows an overall perspective view of a mounting tool 10 showing an embodiment of this invention. In the figure, 1
Reference numeral 1 indicates a prismatic tool body made of impact-resistant hard synthetic resin or the like and having a roughly rectangular cross section. Approximately in the upper and lower center of the left side surface 12 of this tool body 11 is a long pressing protrusion 1 having a rectangular cross section.

A projecting end portion 15 that projects slightly from one end surface 14 of the tool body 11 is provided at one end of the pressing projection 13 . Furthermore, a long pressing protrusion 17 having a rectangular cross section is provided along the longitudinal direction of the tool body 11 at approximately the left and right centers of the lower surface 16 of the tool body 11 . In this case as well, the tool body 11 is attached to one end of the pressing protrusion 17.
A protruding end portion 18 that protrudes slightly from one end surface 14 of
is provided.

In this embodiment, one pressing protrusion 13
The height measured from the left side surface 12 of the other pressing protrusion 17 is, for example, 7 mm, and the height measured from the lower side surface 16 of the other pressing protrusion 17 is, for example, 5 mm.
3 and 17 have different heights.

On the other hand, on the one end side of the tool main body 11, in the upper surface 19 which does not have the above-mentioned pressing protrusions 13 and 17,
A protruding base portion 21 having a reference surface 20 along the upper side surface 19 is provided to protrude laterally. A short pressing protrusion 22 having a rectangular cross section and oriented in the transverse direction of the tool body 11 and parallel to the reference plane 20 is provided to protrude from the protruding base portion 21 .

Next, FIG. 2 shows a perspective view of the joint bar 5 used in the present invention. This joint bar 5 is
A joint bar main body 23 made of flexible synthetic resin such as polyvinyl chloride resin and having a generally T-shaped cross section, and a core material 2 that is also roughly T-shaped and installed inside the joint main body 23.
It basically consists of 4. The protruding portion 25 of the joint bar main body 23 has a roughly "I" shaped cross section.
A pair of left and right fin pieces 26, 26 projecting to both sides are attached to the side surface portion of the projecting portion 25 along with left and right wing portions 27, 27 projecting to both sides at the base end side of the projecting portion 25. Two pieces are formed in parallel at symmetrical positions.

Hereinafter, various methods of using the installation tool 10 of the present invention using the above-mentioned joint bar 5 will be explained.

First, the case of deep joint specification will be explained. As a preparatory step, as shown in FIG.
The left and right wing portions 27, 27 of the joint bar main body 23 are brought into contact with the outer surface of the outer wall panel 6 along the joint 7 and temporarily attached.

A high pressing protrusion 13 provided on the left side surface 12 of the tool body 11 is brought into contact. In this case, the tool main body 11 is preferably arranged with the protruding end 15 at one end of the pressing protrusion 13 facing upward. That is, since the position of the pressing protrusion 13 hidden on the back surface of the tool body 11 can be estimated by the protruding end 15, positioning can be easily performed. Then, the side surface of the tool body 11 opposite to the pressing protrusions 13, 17 is repeatedly struck with a plastic hammer 8 or the like, thereby gradually fitting the joint bar 5 into the joint 7. This operation is completed until the left side surface 12 of the tool body 11 comes into contact with the outer surface of the outer wall panels 6, 6, as shown in FIG. In that case, since the height of the pressing protrusion 13 that has entered into the joint 7 is constant, the joint rod 5 will be housed at a constant depth _d1 determined by the pressing protrusion 13. become.

On the other hand, in the case of a shallow joint specification, a similar operation is performed using a low-height pressing protrusion 17 provided on the lower surface 16 of the tool body 11. That is, in that case, as shown in FIG. 5, the depth of the joint bar 5 becomes _d2 , and it can be placed in a shallower position than when the other pressing protrusion 17 is used.

Next, FIG. 6 shows another usage example of the mounting tool 10 of the present invention. In the figure, 28 indicates a sash frame arranged along the outer wall panel 6. In this way, the sash frame 28 often has a complicated shape. Therefore, the recessed surface 29 of the sash frame 28, which has such an intricate shape,
The joint rod 5 inserted into the joint 30 between the surface of the outer wall panel 6 and
1 by means of the pressing protrusion 22 provided in the opening. In that case, first, the tool body 11 is arranged at right angles to the orientation direction of the joints 30 described above. At that time, the reference surface 20 provided on the protruding base portion 21 is arranged to face the recessed surface 29. Then, in this state, the short pressing protrusion 22 provided on the protruding base part 21 is brought into contact with the approximate center of the joint bar 5, and in the same manner, with a plastic hammer 8 or the like, the protruding base part 21 is removed. Opposite tool body 11
The side surface is repeatedly struck until the reference surface 20 abuts against the recessed surface 29.

In addition, as shown in FIG. 7, the outer wall panels 6, 6
When the joint rod 5 is inserted at an angle into the joint 7 between the joints, the pressing protrusion 22 of the protruding base portion 21 is used to make slight adjustments. That is, as shown in the figure, the pressing protrusion 22 is brought into contact with the protruding part of the joint bar 5 on the outside, and by hitting the joint bar 5 little by little with a plastic hammer 8 or the like, the joint bar 5 is pressed into the joint. 7. Make sure it can be stored inside.

Effects of the invention As described above, in this invention, by providing a plurality of pressing protrusions with different heights on the tool body, one
This has the advantage that joints of different depths can be easily constructed using different installation tools. In addition, by providing a protruding base on one end of the tool body and providing a pressing protrusion oriented in the transverse direction of the tool body, it is possible to make delicate adjustments to the joint bar, etc. We were able to provide a versatile and easy-to-use installation tool that allows the jointer to be placed even in complicated places, such as in the vicinity of.
