Description

  The present invention relates to a jig for widening a gap between two adjacent objects. Specifically, the present invention relates to a jig for widening the joint width between adjacent outer wall panels of a building.

  In a building in which the outer wall is composed of a plurality of outer wall panels, a construction method is adopted in which a joint formed between adjacent outer wall panels is filled with an irregular sealing material or a fixed gasket is inserted. In recent years, gaskets are often inserted into joints in consideration of stable quality and ease of construction.

  However, when inserting a standard gasket into the joint, it is necessary to manage the joint width. If the joint width is narrower or wider than the standard, the gasket cannot be inserted, and sealing must be filled as an evacuation measure. Absent.

  Therefore, in order to install the gasket as much as possible, the joint width must be adjusted when the outer wall panel is built. For this reason, when the outer wall panel is installed, when the outer wall panel is installed with a patch having a predetermined joint width sandwiched between the joints, or the joint width after the outer wall panel is installed is narrow, The outer wall panel is fixed to the housing side with the joints widened by inserting or shino.

JP 2000-111301 A

  However, after fixing the outer wall panel to the housing, it is difficult to remove the pad material, and forcibly removing the pad material may damage the edge of the outer wall surface material. In addition, if the joints are widened with burs or shinos after the outer wall panel is installed, the edge of the face material will be damaged by burs or shinos.

  To that end, it was necessary to repair or replace the face material.

  In view of the above problems, the present invention provides a jig for widening the joint width between adjacent outer wall panels of a building and a jig for widening a gap between two adjacent objects. Let it be an issue.

The above-mentioned problem is a jig for widening a gap between two adjacent objects,
A base end portion, provided with a step with respect to the base end portion, provided on a side of the base end portion having a first contact portion, and a first contact portion of the base end portion, A main body piece having a support portion erected in a direction perpendicular to the contact surface of the first contact portion;
A second abutting portion that abuts against the other object, and an operating piece having an insertion hole that penetrates the support portion;
By moving the working piece along the support portion to the base end side of the main body piece, the first contact portion and the second contact portion are opened, and the gap between the objects is widened. It is solved by the widening jig.

  In this widening jig, the first abutting portion and the second abutting portion are opened by moving the operating piece having the second abutting portion to the base end side of the main body piece having the first abutting portion. Since the gap between the objects can be widened, the gap of the object can be widened by the compression operation of moving the operating piece to the base end side of the main body piece. For this reason, there is no need to insert a bar or shino into the gap of the object and pry it open to widen the gap, so that the object is not damaged or broken. Furthermore, since the operation of widening the gap can be performed by the compression operation, the force can be transmitted efficiently, the workability can be improved, and as a result, damage to the object due to a work mistake can be prevented.

  In this widening jig, the support portion may be a bolt, and the operating piece may be moved to the base end portion side of the main body piece by tightening a nut from the open end side of the support portion.

  The movement of the working piece relative to the main body piece is realized by tightening the nut to the support portion made of the bolt provided on the main body piece, so that the operation of widening the gap can be performed by the screw tightening operation. . In addition, since only the screw is tightened, the force is evenly transmitted to the object through the first contact part and the second contact part when the object is widened, so that the force is concentrated on a part of the object. Thus, the object can be prevented from being damaged. Furthermore, since the tightening operation of the nut can be performed with a dedicated electric tool, the burden on the operator can be reduced.

  Further, in this widening jig, an urging means for urging the operating piece to the side opposite to the base end side of the main body piece may be provided between the main body piece and the operating piece.

After the widening operation of the object is completed, when the main widening jig is removed, the working piece is biased by the biasing means to the side opposite to the base end side of the main body piece. The contact portion is separated from the object and the widening jig can be removed. In particular, if the support part of this widening jig is a bolt and the operating piece can be moved to the base end side of the main body piece by tightening with a nut, just loosen the nut. Because the operating piece is urged by the urging means, the operator does not need to move the operating piece, and the operator can easily use the widening jig even when holding the widening jig in both hands. Can be removed.

  The thickness of the first contact portion and the thickness of the second contact portion are preferably the same.

  Since the thickness of the first contact portion and the second contact portion is the same, by aligning the first contact portion and the second contact portion, the thickness is equal to or greater than the thickness of the first contact portion and the second contact portion. This widening jig can be applied to the gap.

  Further, the object may be an outer wall panel having an outer wall surface material and a base bar arranged on the back side of the outer wall surface material with the side surface aligned with the side surface of the outer wall surface material.

  By applying this widening jig to the outer wall panel, and the outer wall panel having the base bar arranged on the back side of the outer wall surface material with the side surface aligned with the side surface of the outer wall surface material, Since the tool can widen the gap between the outer wall panels by transmitting force to the base rail, it can be widened without further damaging the outer wall surface material.

  Since this invention is as above, the jig | tool which widens the joint width between the adjacent outer wall panels of a building, and the jig | tool which widens the space | gap between two adjacent objects can be performed.

  The main body piece 2 is provided with a rectangular flat plate-like base end 21 and a pair of rising portions 23, 23 protruding obliquely upward from both ends of the side 22 on one side 22 of the base end 21. A pair of first abutting portions 24 that extend outward from the upper end portions of 23 and 23 and are parallel to the base end portion 21 are provided, and the upper surface side of the first abutting portions 24 and 24, that is, the base end portion 21, the side having the first contact portions 24, 24 becomes the contact surfaces 25, 25. A nut is provided as a support portion 26 erected vertically from the base end portion 21 at the central portion of the base end portion 21 on the side having the first contact portions 24, 24. In order to increase the surface rigidity of the main body piece 2, the side 27 opposite to the side 22 having the pair of rising portions 23, 23 of the base end 21 has a side having the support portion 26 with respect to the base end 21. Is provided with a rising plate portion 28 erected vertically in the opposite direction. In addition, 29 is a hole for attaching the strap 7 attached to an operator's belt etc. in order to prevent the widening jig | tool 1 from falling.

  In the operating piece 3, the support portion 26 of the main body piece 2 is inserted into the rectangular flat second contact portion 31 having a width dimension substantially the same as the distance between the pair of first contact portions 24, 24 of the main body piece 2. An insertion hole 32 is formed. Reference numeral 33 denotes an internal hollow cylindrical body that is provided on the same axis as the insertion hole 32 and stabilizes the movement of the operating piece 3 along the support portion 26. The side of the operating piece where the cylindrical body 33 is not provided becomes the contact surface 34. In addition, it is good to use the member of the same board thickness so that the thickness of the 1st contact part 24 and the 2nd contact part 31 may become substantially the same.

  The main body piece 2 and the operating piece 3 are inserted into the support portion 26 of the main body piece 2 through the insertion hole 32 and the cylindrical body 33 with the respective contact surfaces 25 and 34 facing each other. Combined. The spring 4 as the biasing means is attached to the support portion 26 and interposed between the main body piece 2 and the operating piece 3. The nut 5 is attached to the bolt protruding from the cylindrical body 33 via the flat washer 6.

  As shown in FIGS. 3A and 3B, the operating piece 3 can be moved along the support portion 26 with respect to the main body piece 2 by tightening or loosening the bolt 5. The relative position of the operating piece 3 with respect to 2 can be changed.

  In the state where the nut 5 is loosened as shown in FIG. 3A, the operating piece 3 is urged away from the main body piece 2 by the urging force of the spring 4 as urging means. On the other hand, as shown in FIG. 3B, in the state in which the nut 5 is tightened, the operating piece 3 is against the biasing force of the spring 4 as the biasing means as the nut is tightened. The first abutment portion 24 and the second abutment portion 31 of each of the main body piece 2 and the operation piece 3 are moved as the operation piece 3 moves toward the end portion 21 side and the operation piece 3 moves toward the base end portion 21 side of the main body piece 2. The contact surfaces 25 and 34 of the first contact portion 24 and the second contact portion 31 are separated from each other. That is, the contact surfaces 25 and 34 of the first contact portion 24 and the second contact portion 31 can be separated from each other by compressing the main body piece 2 and the operating piece 3 by tightening the nut 5. It is possible to widen the gap by abutting the abutment surface against the respective side surfaces of the two objects having the gap and performing a compression operation. That is, the widening operation of the gap of the object can be realized by performing the compression operation on the widening jig 1.

  Next, the case where this widening jig | tool is used in order to widen the joint width between the adjacent outer wall panels of a building is shown.

  In the outer wall panel 40 shown in FIG. 4, a strip-shaped base bar 42 made of a foamed resin material is arranged on the back side of the outer wall surface material 41 of the ceramic siding material, with its side surface 42 a aligned with the side surface 41 a of the outer wall surface material. In addition, a steel outer wall panel frame 44 is provided on the back side of the base frame 42 via a plate-like fiber-based heat insulating material 43. 45 is a fiber-based heat insulating material filled in the outer wall panel 40.

  Adjacent outer wall panels 40, 40 are integrated with each other by fixing the outer wall panel frames 44, 44 to a pillar material 46 made of channel steel and via the pillar material 46. Reference numerals 47 and 48 denote bolts and nuts for fastening the outer wall panel frame 44 and the column member 46, respectively. Reference numerals 49 and 50 denote a plate-like fiber heat insulating material and a fiber heat insulating material, respectively.

  As shown in FIG. 4 (a), when the width of the joint portion 51 between the adjacent outer wall panels 40, 40 is narrow and needs to be widened, the tightening amount of the nut 5 of the widening jig 1 is adjusted, The first contact portion 24 and the second contact portion 31 of the widening jig 1 are inserted into the joint portion 51 with the first contact portion 24 and the second contact portion 31 aligned on substantially the same plane. To do.

  As shown in FIG. 4B, by tightening the nut 5, the operating piece 3 moves to the base end portion 21 side of the main body piece 2, and the operating piece 3 moves to the base end portion 21 side of the main body piece 2. Accordingly, the first abutting portion 24 and the second abutting portion 31 are separated from each other, and the abutting surfaces 25, 34 push the side surfaces 41a, 41a, 42a, 42a of the abutting outer wall panels 40, 40 apart.

  Then, after the predetermined joint portion 51 is widened to a predetermined joint width, a measure is taken to maintain the joint width widened, such as by inserting a spacer between the outer wall panel frame 44 and the column member 46, and then the outer wall panel 40. And the column material 46 are finally tightened and integrated.

  Finally, as shown in FIG. 4 (c), by loosening the nut 5, the actuating piece 3 is urged away from the body piece 2 by the urging force of the spring 4, and the contact surfaces 25, 34 are formed on the outer wall. The widening jig 1 can be extracted from the joint portion 51 away from the side surfaces 41 a and 42 a of the panels 40 and 40.
