Since it is necessary to prevent water outside the outer wall panel from entering inside, the joint is filled with a sealing material. Patent Literatures 1 and 2 disclose tools provided with rollers for filling joints with a sealing material.

Japanese Patent No. 6121277 Japanese Patent No. 6065949

The tools of Patent Documents 1 and 2 are tools for filling the joints of the outer wall with a sealant when building a new building or the like, so they are assumed to be used in a situation where there is scaffolding around the outer wall. . Therefore, for example, if a part of the sealing material comes off the joint at a high place such as the second floor of the building due to an external factor such as an earthquake after the completion of the building, etc., it is necessary to use a ladder or the like to work. No, it's a lot of work.

The present invention has been made in view of the above circumstances. It is the main objective of the present invention to make it compressible.

Hereinafter, effective means for solving the above problems will be described while indicating the action, effect, etc. as necessary. In the following, for ease of understanding, reference numerals indicating corresponding configurations are shown in parentheses in the drawings, but the present invention is not limited to the specific configurations and shapes shown in the drawings.

A first invention is a tool for pushing a sealing material (88) into a joint (86) between outer wall panels (81), wherein the tool is brought into contact with the joint (86) and rotated in the longitudinal direction of the joint (86). By moving, a roller (30) for pushing the sealing material (88) into the joint (86) and a roller mounting portion (20) to which the roller (30) is rotatably mounted are telescopically and a telescopic pole (10) having the roller attachment portion (20) attached to the tip thereof.

According to the first invention, even if a part of the sealing material (88) is removed from the joint (86) at a high place out of the reach of the worker (H), the worker (H) can use the telescopic pole ( 10), the base end of the telescopic pole (10) is held and the roller (30) is operated to push the sealing material (88) into the joint (86) without using a ladder or the like. can.

A second invention is based on the first invention, wherein the telescopic pole (10) has a plurality of cylindrical bodies (11a to 11e) arranged in the length direction of the telescopic pole (10), and each of the cylindrical bodies (11a 11e), in the extensible pole (10), the outer circumference of the telescopic pole (10) that constitutes the distal end side is gradually smaller than that of the telescopic pole that constitutes the proximal end side. By housing the cylinder on the distal end side relatively inside the cylinder on the side, the telescopic pole (10) is contracted, and the cylinder on the distal end side is moved from the inside of the cylinder on the proximal end side to the cylinder on the distal end side. is pulled out to extend the telescopic pole (10). According to the second invention, the first invention can be implemented simply.

In the third invention, in the second invention, the most proximal side cylindrical body ( 11e), the diameter of the roller (30) is larger than the longitudinal size of the roller (30).

According to the third aspect of the invention, the center line of the roller (30) is arranged on the extension line of the center line of the telescopic pole (10), and even when the telescopic pole (10) is erected vertically, the most proximal side The front end of the roller (30) protrudes forward more than the front end of the cylinder (11e). Therefore, the roller (30) is pushed to the sealing material (88) before the cylindrical body (11e) closest to the proximal end or the hand of the worker (H) holding it comes into contact with the lower part of the outer wall (80). Easy to contact parts. Therefore, it is convenient to use the sealing material pushing tool in a narrow space or the like.

According to a fourth invention, in the first to third inventions, the total length of the seal material pushing tool when the telescopic pole (10) is stretched to the maximum is 3 to 20 m. According to the fourth aspect of the invention, since the total length of the sealing material pressing tool is 3 m or more, it can be used even at a considerable height. Moreover, since the length is 20 m or less, the sealing material pressing tool does not become excessively heavy.

FIG. 2 is a cross-sectional bottom view showing the sealing material pressing tool of the first and third embodiments;

Next, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments, and can be modified as appropriate without departing from the gist of the invention.

[First Embodiment]
The first embodiment implements the first to fourth inventions. FIG. 1(a) is a side view showing the sealing material pressing tool 51 of the first embodiment. The sealing material pressing tool 51 includes a telescopic pole 10 , a roller mounting portion 20 and a roller 30 .

The telescopic pole 10 is composed of a plurality of cylindrical tubular bodies 11a to 11e arranged in the longitudinal direction. In the extensible pole 10, the cylindrical bodies 11a to 11e that form the distal end side are successively smaller in diameter than those that form the proximal end side. The telescopic pole 10 has a relatively distal side cylindrical body (for example, 11b) housed inside a relatively proximal side cylindrical body (for example, 11c), so that the overall length of the extensible pole 10 is reduced. The overall length is extended by pulling out the cylinder on the tip side relatively from the inside of the cylinder.

The telescopic pole 10 is made of a non-conductive material. This is to prevent lightning from striking the telescopic pole 10 when working with the telescopic pole 10 extended. In this embodiment, the material is glass fiber.

A fixture 12 is provided at the distal end of each of the cylinders 11b to 11e except for the cylinder 11a on the most distal end side. The fixture 12 for each of the cylinders 11a to 11e is for fixing the cylinder located on the tip side (inside) of the cylinder by a desired length. Specifically, each fixture 12 is configured to be fixed by tightening the inner cylinder from the outside, and to release the fixation by releasing the tightening.

More specifically, each fixture 12 includes a ring 12a attached to the tip of the cylindrical body and a lock lever 12b pivotally attached to the ring 12a. When the lock lever 12b is rotated in one direction, the ring 12a is tightened by contracting the diameter of the ring 12a.

The most tip side (inner) cylinder 11a is slightly longer than the other cylinders 11b to 11e. Therefore, even when the telescopic pole 10 has the shortest overall length, the distal end portion of the cylindrical body 11a closest to the distal end side protrudes ahead of the distal ends of the other cylindrical bodies 11b to 11e.

The total length of the sealing material pushing tool 51 when the telescopic pole 10 is contracted to the maximum is about 1.5 m. Further, the total length of the sealing material pushing tool 51 when the telescopic pole 10 is extended to the maximum is about 12 m. Of course, these dimensions can be changed as appropriate, but the total length of the sealing material pushing tool 51 when the telescopic pole 10 is contracted to the maximum is preferably 1 to 3 m. If the length is less than 1 m, the number of cylinders 11a to 11e required to be able to extend to the desired length may become too large. Because it is possible.

On the other hand, the total length of the sealing material pushing tool 51 when the telescopic pole 10 is stretched to the maximum is preferably 3 m or more as described in the fourth invention. The total length is more preferably 5 m or more, more preferably 7 m or more, in that the roller 30 can reach a sufficiently high place. Moreover, the total length is preferably 20 m or less as described in the fourth invention. The total length is more preferably 17 m or less, more preferably 15 m or less, in order to further reduce the weight of the sealing material pressing tool.

The outer diameter of the cylinder 11a closest to the tip is about 20 mm. The outer diameter of the cylindrical body 11e closest to the proximal end is approximately 60 mm. Of course, these dimensions can also be changed as appropriate.

The roller 30 is rotatably attached to the tip of the telescopic pole 10 by the roller attachment portion 20 . The center of the roller 30 is arranged on the extension line of the center line of the telescopic pole 10 .

The diameter of roller 30 is approximately 75 mm. Of course, the diameter can be changed as appropriate, but it is preferably 55 mm or more for reasons described later. Moreover, the diameter is preferably 150 mm or less. This is because if the length exceeds 150 mm, the roller 30 becomes too large and the distal end of the telescopic pole 10 becomes too heavy, which may make it difficult to operate the telescopic pole 10 from the proximal end. The diameter is more preferably 120 mm or less in that the telescopic pole 10 is easier to operate.

FIG. 1(b) is a rear view showing the sealing material pressing tool 51. FIG. The roller mounting portion 20 is a metal fitting, and includes two supporting arms 23 arranged side by side with an interval in the width direction, and a connecting portion 22 connecting the proximal ends of the two supporting arms 23. ing. An intermediate portion of the connecting portion 22 is non-rotatably fixed with a bolt B to the distal end portion of the cylindrical body 11a closest to the distal end side.

The roller 30 is arranged between the two support arms 23 and is pivotally attached to the two support arms 23 via the support shaft 24 . Specifically, the support shaft 24 is a bolt passing through the two support arms 23 . The support shaft 24 has a male threaded portion at its tip, and a nut 24a is screwed onto the male threaded portion. Both ends of the roller 30 in the width direction are provided with chamfered portions 34 having rounded corners. The chamfered portion 34 has a curved shape.

The width of roller 30 is about 16 mm. Of course, the width can be changed as appropriate, but the width of the roller 30 is preferably 10 to 20 mm, since it is preferable that the width of the roller 30 is a size that just fits in the joint 86 of a general size.

FIG. 2 shows a state in which the sealing material pressing tool 51 is used. A sealing material 88 is fitted in the joint 86 of the outer wall panel 81 . The sealing material 88 is a standard seal in this embodiment. First, the worker H visually confirms the state of the sealing material 88 . When it is found that a part of the sealing material 88 is detached from the joint 86, the telescopic pole 10 is extended to an appropriate length to reach the detached part of the sealing material 88. - 特許庁Then, by holding the cylindrical body 11e closest to the base end (outside) and operating the telescopic pole 10, the roller 30 is brought into contact with the part of the sealing material 88 where the seal material 88 is removed. In this state, the extensible pole 10 is operated to rotate the roller 30 in the longitudinal direction of the joint 86 , thereby pushing the sealing material 88 into the joint 86 . The rotational movement may be performed multiple times by reciprocating the roller 30 along the joint 86 .

FIG. 3 is a cross-sectional plan view showing the state of the sealing material pressing tool 51 when it is used. A groove-shaped joint 86 is formed between the outer wall panels 81 , and a sealing material 88 is fitted on the far side of the joint 86 . The front side of the joint 86 forms a groove 86a having the surface of the sealing material 88 as the bottom surface and the side surfaces of the two outer wall panels 81 as the inner surface. Both inner side surfaces of the groove 86a are sloped surfaces 87 that are inclined in such a manner that the width of the groove increases from the back side to the front side. The chamfered portion 34 of the roller 30 contacts the inclined surface 87 . The roller 30 is thereby guided along the length of the joint 86 .

Next, the reason why the roller 30 preferably has a diameter of 55 mm or more will be described. If the surface of the outer wall panel 81 has an uneven pattern or the like, as shown in FIGS. Concave and convex portions are formed. In this case, as shown in FIG. 4(a), if the diameter of the roller 30 is less than the predetermined length, when the roller 30 comes to the side of the recessed portion 83, the rollers 30a, 30b, 30c, 30c, 30d, 30d, 30d, 30d, 30d, 30d, and 30d and 30d adjacent to the recessed portion 83 will not be in contact with each other. Since the roller 30 is not placed on the right side of the convex portion 84 of the roller 30, the roller 30 tends to shift sideways. As a result, the roller 30 is easily disengaged from the joint 86 .

In this respect, as shown in FIG. 4(b), if the diameter of the roller 30 is equal to or greater than the predetermined length, when the roller 30 comes to the side of the recessed portion 83, any portion adjacent to the recessed portion 83 will not move. Since the roller 30 is placed right beside the convex portion 84 of the roller 30, the roller 30 is less likely to be displaced to the side. Therefore, the roller 30 is less likely to come off the joint 86 . Although the predetermined length varies depending on the shape of the uneven pattern, the general predetermined length was 55 mm when the present inventor tried it. For the above reasons, the diameter of the roller 30 is preferably 55 mm or more as described above. The diameter is more preferably 65 mm or more in that the roller 30 is less likely to come off the joint 86 .

According to this embodiment, even if a part of the sealing material 88 is separated from the joint 86 at a high place such as the second or third floor of the building, which is out of reach of the worker H, the ladder or the like can be hung. The sealing material 88 can be pushed into the joint 86 without any need.

In addition, since the diameter of the roller 30 (75 mm) is larger than the diameter (60 mm) of the cylindrical body 11e closest to the proximal end, even when the telescopic pole 10 is vertically erected, the cylindrical body 11e closest to the proximal end can be The front end of the roller 30 protrudes forward from the front end of the roller 30 . Therefore, the roller 30 can be brought into contact with the target portion of the sealing material 88 before the cylindrical body 11e closest to the proximal end or the hand of the worker H holding it comes into contact with the lower portion of the outer wall 80 . Therefore, the sealing material pushing tool 51 is easy to use in a narrow space or the like.

[Second embodiment]
Next, a second embodiment will be described. This embodiment implements the fifth invention in addition to the first to fourth inventions. Regarding this embodiment, only the points that are different from the first embodiment will be described.

FIG. 5 is a side view showing the sealing material pressing tool 52 of the second embodiment. The roller mounting portion 20 includes an arm 21 extending from the intermediate portion of the connecting portion 22 to the side opposite to the roller 30 side. The end portion of the arm 21 is attached to the tip portion of the telescopic pole 10 via a rotation adjustment mechanism 21a so as to be rotatable about an axis extending parallel to the axis of the roller 30. As shown in FIG. By this rotation adjustment, the arm 21 rotates around the end, and the angle of the arm 21 in the length direction with respect to the length direction of the telescopic pole 10 is changed. Thereby, the position of the roller 30 with respect to the tip of the telescopic pole 10 is changed. Therefore, the center of the roller 30 can be arranged on the extension line of the center line of the telescopic pole 10, or can be arranged at a position shifted forward from the extension line.

According to this embodiment, the following effects can be obtained in addition to the effects of the first embodiment. By adjusting the rotation, the position of the roller 30 with respect to the tip of the telescopic pole 10 can be appropriately adjusted to a position where it is easy to apply force to the sealing material 88 . Further, even if the angle at which the operator H holds the telescopic pole 10 changes, the roller 30 can be brought into contact with the joint 86 at an appropriate angle by adjusting the rotation.

[Third embodiment]
Next, a third embodiment will be described. Regarding this embodiment, only the points different from the first embodiment will be described.

FIG. 6(a) is a bottom cross-sectional view showing the sealing material pressing tool 51 of the first embodiment, and more specifically, a cross-sectional view taken along line VIa-VIa shown in FIG. 1(b). On the other hand, FIG. 6(b) is a bottom cross-sectional view showing the sealing material pressing tool 53 of this embodiment. Hereinafter, the width direction of the roller 30 is defined as the left-right direction, and the direction perpendicular to the length direction of the telescopic pole 10 and the left-right direction is defined as the front-rear direction. In this embodiment, each of the cylinders 11a to 11e has a cross-sectional shape that is longer in the front-rear direction than in the left-right direction. Specifically, each of the cylindrical bodies 11a to 11e has an elliptical cylindrical shape with a short axis extending in the left-right direction and a long axis extending in the front-rear direction.

According to this embodiment, the following effects can be obtained in addition to the effects of the first embodiment. Since each cylindrical body 11a to 11e has a cross-sectional shape that is longer in the front-rear direction than in the left-right direction, the telescopic pole 10 is particularly difficult to bend in the front-rear direction. Therefore, when the sealing material 88 is pushed into the front joint 86 by the roller 30, the tip side of the telescopic pole 10 can be prevented from bending backward due to the reaction force.

[Other embodiments]
The above-described first to third embodiments can also be implemented with the following modifications. For example, instead of forming the extensible pole 10 from glass fiber, it may be formed from carbon fiber, various resins, various metals, or the like.

Further, instead of arranging the center of the roller 30 on the extension line of the center line of the telescopic pole 10, the center of the roller 30 may be arranged at a position shifted forward from the extension line. In this case, the forward protrusion length of the roller 30 is increased. Therefore, even if the front end of the telescopic pole 10 warps backward due to the reaction force pushing the sealing material 88 , the roller 30 can be reliably brought into contact with the sealing material 88 .

Further, instead of cylindrical or elliptical cylindrical bodies 11a to 11e, they may be rectangular cylindrical or hexagonal cylindrical. Further, the cylindrical body 11a on the most distal end side may be changed to a rod body having no cylindrical hole inside. Further, instead of constructing the extensible pole 10 from a plurality of cylindrical bodies 11a to 11e, it may be constructed from a single cylindrical body and a single rod inserted therein.
