Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention uses a circular saw to cut the exterior wall material attached to the exterior of a house, such as corrugated iron, square corrugated iron, or plasterboard. This article relates to a workbench for cutting exterior wall materials.

(Prior art) Generally, when pasting an exterior wall material such as corrugated iron, it may be necessary to cut it into an appropriate shape. For example, when covering the upper edge of a house's gable side, Exterior wall materials must be cut diagonally to match the slope. For this reason, conventionally, marking lines were placed on the exterior wall material according to the slope, and cuts were made along these lines with a circular saw or with scissors.

(Problems to be Solved by the Invention) However, when cutting exterior wall materials, especially boards with irregularities, with a circular saw, skill is required to move the circular saw linearly along the marking lines. Furthermore, cutting corrugated iron or the like with metal scissors requires skill, and there are drawbacks such as the irregularities of the corrugated iron being crushed and the cut edges not being clean.

The present invention was developed based on the above-mentioned circumstances, and allows for efficient cutting of exterior wall materials in diagonal directions depending on the installation location without much effort.
To provide a workbench for cutting exterior wall materials that does not cause the cut portion to bend or collapse and can be quickly and neatly finished.

[Structure of the idea]

(Means for Solving the Problems) In order to achieve the above object, the workbench for cutting external wall materials according to the present invention has an opening extending between both side walls in the upper wall of the box-shaped main body. A receiving plate that closes the opening is pivotally attached to the back surface of the upper wall so as to be able to swing freely along the back surface of the upper wall, and a groove that faces the opening and intersects with the longitudinal direction of the upper wall is formed in the receiving plate. A presser plate facing the receiving plate is provided so as to be openable and closable vertically via a hinge vertically adjustable on the side wall, and the presser plate is attached along the upper surface of the upper wall relative to the hinge. It is characterized in that it is pivotally attached to the top wall so as to be able to swing, and that a ruler piece that intersects with the longitudinal direction of the upper wall is provided on the holding plate.

(Example) An example of the working table for cutting exterior wall materials according to the present invention will be specifically described below with reference to the drawings. The workbench of this invention has an opening 3 extending between both side walls 6, 6 on the top wall 2 of a main body 1 having a box shape, and a receiving plate 4 that closes the opening 3 on the back side of the top wall 2 along the top wall 2. A holding plate 5 facing the receiving plate 4 is provided so as to be vertically openable and closable via a hinge 7 attached to a side wall 6. The opening 3 has a trapezoidal shape that gradually becomes wider from one side wall 6 to the other side wall 6. The receiving plate 4 is pivotally attached to a shaft support piece 8 that projects inside a side wall 6 on the narrow side of the opening 3. The receiving plate 4 has a substantially fan shape centered on its pivot point, has a groove 10 intersecting the longitudinal direction of the upper wall 2, and has thick edges 23, 23 on both sides of the groove 10. Plate pieces 9, 9 are connected to the back surface of the upper wall 2 through the intermediary, and each plate piece 9, 9 has a receiving plate 4.
An arcuate hole 24, 24 having an arcuate shape centered on the pivot point of
A bolt 11 with a nut inserted into the arcuate hole 24 is fixed to the back surface of the upper wall 2 to suspend and support the receiving plate 4 and to make the swinging of the receiving plate 4 smooth. The thick edge 23 of the groove 10 is on the same plane as the upper wall 2, and the thick edge 23 limits the swing range of the receiving plate 4.
It is regulated until it is locked to the periphery of the opening 3. The presser plate 5 is attached via a hinge 7 to the outer surface of a side wall 6 having a shaft support piece 8 . Hinge 7 is
A pair of vertical holes 1 are formed in a fixed piece 14 fixed to one of the pieces.
Bolts 13 are drilled through holes 5 and 15 and protrude from the side wall 6.
is inserted into the vertical hole 15 and tightened with a mounting nut 16, and the hinge 7 is inserted within the vertical hole 15.
can be adjusted up and down. Further, a presser plate 5 is pivotally attached to one end of a movable piece 17 fixed to the other piece of the hinge 7 so as to be able to swing along the movable piece 17, and an arcuate hole 18 is formed in the presser plate 5 around the pivot point. At the same time, a bolt 19 protruding from the other end of the movable piece 17 is inserted to restrict the swinging range of the presser plate 5, and a tightening nut 20 screwed onto the bolt 19 is used to attach the presser plate 5 to the movable piece 17. It seems to be fixed. The presser plate 5 can be opened and closed vertically by the hinge 7 from a state parallel to the upper wall 2 to a state almost perpendicular to the upper wall 2, and
A ruler piece 2 intersecting the longitudinal direction of the upper wall 2 is attached to the holding plate 5.
1 is provided. Further, a reference piece 22 is attached to the side wall 6 to which the holding plate 5 and the receiving plate 4 are attached, and stands upwardly from the upper wall 2 along the longitudinal direction of the upper wall 2.

The proposed workbench has the above-mentioned configuration, and when cutting the exterior wall material 30, first, the presser plate 5 is swung along the upper wall 2, and the ruler piece 21 is placed at a predetermined position with respect to the reference piece 22. angle and fix with a tightening nut 20. Then, the receiving plate 4 is swung so that the groove 10 is positioned directly below the ruler piece 21. moreover,
The hinge 7 is moved up and down within the range of the vertically elongated hole 15, the distance between the presser plate 5 and the upper wall 2 is adjusted to the thickness of the outer wall material 30, and then fixed with a mounting nut 16. Then, open the presser plate 5 upward, place the outer wall material 30 on the upper wall 2, align the side edge of the outer wall material 30 with the reference piece 22, position the part to be cut on the groove 10, and press the Close plate 5 again. Then, the guide member 3 of the circular saw 31
2 along the guide wall 21, the outer wall material 30 is cut.

In addition, a reference piece 22 is placed around the circular arc hole 18 of the holding plate 5.
If a scale is provided to indicate the angle of inclination of the ruler piece 21 relative to the angle, the setting becomes easier.

[Effect of idea]

The workbench for cutting exterior wall materials according to the present invention has an opening in the upper wall of the box-shaped main body extending between both side walls, and a hinge attached to the side wall above the opening. The holding plate is pivoted so that it can swing along the upper wall, and the holding plate has a ruler piece that crosses the longitudinal direction of the upper wall, making it easy to set the cutting angle of the exterior wall material. . In addition, the holding plate is attached to the side wall via a hinge that can be adjusted up and down, so the distance between the holding plate and the top wall can be adjusted according to the thickness of the external wall material to be cut, allowing you to tighten the external wall material. can be held. Furthermore, a receiving plate that closes the opening is pivotally attached to the back of the upper wall so that it can swing along the upper wall, and the receiving plate is provided with an upward groove that intersects with the longitudinal direction of the upper wall. The lower end of the saw blade goes into the groove, and the outer wall material can be held by the receiving plate and holding plate. From the above, if the workbench of the present invention is used, the exterior wall material can be quickly cut with a circular saw even at any angle of inclination without crushing or rattling the unevenness, and the cut is also clean.
