Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device for obliquely cutting members such as a frame material and a core material forming a triangular panel used in a roof of a prefabricated house or the like.

[0002]

2. Description of the Related Art Generally, in a wooden prefabricated house, a wall, a floor, a roof, etc. are constructed by a wooden panel composed of a frame body and a face material attached to at least one surface of the frame body. Means are being implemented. In such a construction method, for example, a triangular roofing panel is used for a gable wall portion of a gable roof house. This roofing panel
A frame is composed of a frame material that is assembled in a triangular shape according to the contour of the roofing panel and core materials that are arranged vertically and horizontally inside the frame material, and a triangular face plate is provided on one or both sides of the frame body. It is pasted.

In order to manufacture this roofing panel, it is necessary to cut the end faces of the frame members assembled in the triangular shape and the end faces of the core member joined to the inclined frame members at an angle corresponding to the inclination of the roof. was there. Conventionally, when cutting the end faces of the frame and the core diagonally, an electric saw whose cutting direction is freely rotatable or a work in which the fixing angle of the frame and the core can be freely set I was using a stand.

[0004]

By the way, the roof panel has various shapes corresponding to various roof inclinations. Therefore, the angles of the end faces of the frame member and the core member forming the roofing panel also differ depending on the roof panel. Further, the frame material and the core material, if the angle of the end surface of the frame material and the core material is incorrect, the shape of the roofing panel may be incorrect, or the strength of the roofing panel may be reduced, It is required to cut at an accurate angle. Therefore, a skillful technique is required for cutting the frame material and the core material.

From the above, the work of cutting the frame and the core material requires the accurate cutting of the frame and the core material at various angles, which is troublesome. The present invention has been proposed in view of the above circumstances, and an object thereof is to provide a cutting device capable of easily cutting a member such as a frame or a core at an arbitrary and accurate angle. Is.

[0006]

A cutting device of the present invention is for cutting a member to be cut at an arbitrary angle, and includes a fixing base for fixing the member and an electric saw for cutting the member. A rotary table that supports the electric saw rotatably and movably along the cutting direction; and a cutting angle determining unit that determines an angle of the rotary table. The fixed table horizontally holds the member. A work plate for placing the work plate, a fixed ruler provided on the work plate for restricting the direction of the member, and a pressing portion for fixing the member by pressing the member toward the fixed ruler. The rotary table is provided with a vertically-supported support shaft, a turntable rotatably provided on the support shaft, and the turntable provided on the turntable in a cutting direction. And a guide rail movably supported along The angle determining portion has a slide lever, a slide rail that horizontally movably supports the slide lever, one end fixed to the turntable, and the other end attached to the slide lever. A rod-shaped connecting portion that is movable in the vertical direction and is rotatably supported in a horizontal plane is provided as a means for solving the above problems.

[0007]

According to the above construction, the member to be cut is fixed on the work table by the pressing means and the fixed ruler. The turntable can be rotated via the connecting portion by moving the slide lever on the slide rail. Therefore, the angle of the turntable can be determined by determining the position of the slide lever on the slide rail.

Since the electric saw is movable along the cutting direction of the electric saw by the guide rail on the turntable, the member is cut by moving the electric saw along the guard rail. be able to.
