DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for processing an inner wall surface of a corner panel forming a corner of an outer wall of a building. More specifically, the present invention relates to a corner panel inner wall surface cutting device suitable for use in cutting an inner wall surface of a lightweight cellular concrete corner panel having an uneven surface pattern.

[0002]

2. Description of the Related Art In recent years, as a corner panel to be attached to a corner portion of an outer wall of a house or the like, a lightweight cellular concrete corner panel integrally formed into a substantially V-shaped cross section by applying an uneven decorative pattern to the outer wall surface has been provided. When this type of corner panel is mounted on a housing unit, which is a structural body of a so-called unit-type pre-hap house, the panel is arranged along the prism of the unit, and the upper and lower parts are fixed with metal fittings.

[0003] In such a corner panel mounting structure, a step is formed between the assembled corner panel and an adjacent flat panel, despite the fact that the frame of the housing unit is made of steel and has good dimensional accuracy. There is. One of the causes is that an error occurs in the thickness of the corner panel produced by integral molding or in the parallelism between the outer wall surface and the inner wall surface. The corner panel and the flat panel cannot usually be adjusted in and out of the skeleton, so that when the error is large, it appears as a step on the outer wall surface.

In the case of a corner panel having an error in dimensions, when the thickness dimension is large, the above problem can be solved by cutting the inner wall surface to increase the dimensional accuracy. It is desirable to be mechanized in terms of safety and health, standardization of work efficiency and accuracy.

As an apparatus for cutting a corner panel, there is an apparatus described in Japanese Utility Model Registration No. 2534016. This device is for chamfering some corners of the corner panel and is different from the application of the present invention, but after placing the corner panel on the roller of the roller conveyor, it is moved on the roller. In addition, the corner of the corner panel is cut by a cutting blade operating at a fixed position.

[0006]

However, when the inner wall surface is cut by a cutting device in which such a corner panel itself moves on a roller, a corner made of lightweight cellular concrete having an uneven pattern on the outer wall surface is obtained. In the panel, there is a problem that the uneven pattern is chipped or scratched when it is placed on a roller or moved during cutting. In addition, as an installation space for the apparatus, a space at least twice as long as the entire length of the corner panel (a space for mounting the pre-cut corner panel and a space where the corner panel is cut and moved) is required. For example, when processing a corner panel having a total length of about 3 m, which is close to the height of the first floor of a building, the entire length of the device is required to be approximately 7 m to 10 m, and the installation space of the device becomes extremely large. Further, when processing a corner panel having a different angle between two surfaces, it is necessary to adjust the roller mounting angle over the entire length of the roller conveyor, and this adjustment requires a great deal of labor.

Accordingly, a first object of the present invention is to provide an apparatus for cutting an inner wall surface of a corner panel capable of cutting the inner wall surface without damaging the outer wall surface of the corner panel and having a small installation space. It is in. Further, a second object of the present invention is to cut various types of corner panels in which the inner wall surface can be cut without damaging the outer wall surface of the corner panel, the installation space is small, and the corner angle is different. However, an object of the present invention is to provide a corner panel inner wall cutting device in which device adjustment is extremely easy.

[0008]

The first object of the present invention is achieved by supporting an outer wall surface of a corner panel having a substantially V-shaped cross section on a V-shaped base surface covered with a panel outer wall surface protecting material. A corner panel mounting table, a tool mounting table on which a tool for cutting the inner wall surface of the corner panel is mounted, and moving means for moving the tool mounting table over the entire length of the corner panel mounting table. An apparatus for processing an inner wall surface of a corner panel.

In order to solve the second problem,

By using the panel outer wall surface protection material 2, it is possible to prevent the unevenness pattern on the outer wall surface from being chipped or damaged due to an impact when the corner panel 50 is placed, a vibration generated at the time of processing the inner wall surface, or the like.

The tool 5 is for cutting the inner wall surface of the corner panel 50, and has a V-shaped cutting blade 5a having the same shape as the inner wall surface of the corner panel 50 as shown in FIG. As shown in FIG. 3, the V-shaped cutting blade 5a is provided with blades on both sides, so that the tool mount 6 can be moved in any direction by the moving means 7 during cutting. The inner wall surface of the corner panel 50 can be cut.

The tool mount 6 is for fixing the tool 5 so that the position of the tool 5 can be adjusted. As shown in FIG.
A first position adjusting plate 6b fixed to the base 6a, a second position adjusting plate 6c engaged with the first position adjusting plate 6b and provided to be movable in the vertical direction, Position adjustment plate 6
The third position adjusting plate 6d is provided so as to be movable in the left-right direction by engaging with the third position adjusting member 6c, and the cutting blade mounting plate 6e fixed to the third position adjusting plate 6d.

As shown in FIG. 2, the base 6a is fixed to a reciprocating part 12 of a moving means 7 described later, and moves with the reciprocating movement of the reciprocating part 12 (arrow F in FIG. 1). The tool 5 is configured to move along with the movement of the reciprocating unit 12 to cut the inner wall surface of the corner panel 50.

On the side of the position adjusting plate 6b, there is provided a first engaging concave portion 14 extending in the vertical direction for engaging with the first engaging convex portion 13. Then, by rotating the vertical position adjusting screw 15 provided on the first position adjusting plate 6b, the second position adjusting plate 6c moves in the vertical direction (G direction in FIG. 3). The position of the tool 5 can be adjusted by moving up and down.

The second position adjusting plate 6c is provided with a second engaging projection 16 extending in the lateral direction for engaging with the third position adjusting plate 6d. Second
On the side of the position adjusting plate 6c, there is provided a second engaging concave portion 17 extending in the lateral direction for engaging with the second engaging convex portion 16. Then, by rotating the left / right position adjustment screw 18 provided on the second position adjustment plate 6c, the third position adjustment plate 6d is moved in the left / right direction (H direction in FIG. 3), and accordingly. The position of the tool 5 can be adjusted by moving the tool 5 left and right.

Further, a cutting blade mounting plate 6e is fixed to the third position adjusting plate 6d.
Is fixed to the tool 5. In this embodiment, when cutting a corner panel having a different corner angle, it is necessary to replace the tool 5 with a tool having a V-shaped cutting blade having the same shape as the inner wall surface of the corner panel.

The moving means 7 is for moving the tool mounting table 6 over the entire length of the corner panel mounting table 4, and includes a reciprocating unit 12 and a reciprocating unit 1 as shown in FIG.
2, a pulley 21 on which the endless chain 20 is mounted at one end,
A sprocket 22 having an endless chain 20 mounted on the other end side, and a drive motor 23 capable of rotating the sprocket 22 forward and reverse through a speed reducer and changing the speed.

As shown in FIG. 2, the reciprocating portion 12 is formed in a portal type as viewed from the side, is disposed so as to straddle the corner panel mounting table 4, and is slidably mounted on rails 24a and 24b. I have. When the drive motor 23 is driven, the sprocket 22 and the endless chain 20 rotate, and the reciprocating portion 12 is pulled by the endless chain 20, and moves on the rails 24a and 24b over the entire length of the corner panel mounting table 4. It is configured to be.

Next, a method of using the corner panel inner wall surface cutting device 1 of the present invention will be described. When the inner wall surface of the panel is cut by the inner panel wall cutting device 1 of the present invention, first, the corner angle of the outer wall surface of the panel and the angle of the V-shaped base surface 3 of the corner panel mounting table 4 are the same. Thus, the opening angle of the V-shaped platform 3 is set by adjusting the position in the long hole 10 of the binding means 11. On the other hand, on the tool 5 side, a tool having the same V-shaped cutting blade 5a as the corner angle of the inner wall surface of the panel is selected and fixed to the tool mount 6. Further, the vertical position adjusting screw 15 and the horizontal position adjusting screw 18 adjust the position of the V-shaped cutting blade 5a in the vertical and horizontal directions.

Then, the corner panel 50 to be cut is formed.
Is mounted such that the outer wall surface of the base plate abuts on the V-shaped base surface 3 of the corner panel mounting table 4. At this time, since the V-shaped base surface 3 is covered with the panel outer wall surface protecting material 2, the outer wall surface is not damaged even if the corner panel 50 is placed.

In this state, when the driving motor 23 is driven, the reciprocating part 12 moves to the other end in the horizontal direction via the sprocket 22 and the endless chain 20, and the V-shaped cutting blade of the tool 5 is moved with this movement. 5a cuts the inner wall surface of the corner panel 50. Thus, in the present invention, since the tool 5 is moved without moving the corner panel itself,
Even if it is a corner panel made of lightweight cellular concrete having an irregular pattern on the outer wall surface, the outer wall surface will not be damaged during movement, and the installation space for the device is sufficient for the entire length of the corner panel.

Further, when the reciprocating unit 12 moves to the other end, it is replaced with another corner panel and placed.
The drive motor 23 is rotated in the reverse direction to move the reciprocating unit 12 to the initial position. At this time, since the V-shaped cutting blade 5a of the tool 5 has blades on both sides, it is possible to cut the inner wall surface of the corner panel and cut two corner panels in one reciprocation. However, if necessary, one corner panel 50 may be used for cutting in a reciprocating process.

Next, another embodiment of the present invention shown in FIGS. 4 and 5 will be described. The difference between the corner panel inner wall surface cutting device 30 of this embodiment and the corner panel inner wall surface cutting device 1 described above is that a tool 31 and an angle-adjustable tool mounting plate 32 are provided instead of the cutting blade mounting plate 6e. Only the point is the other. The same components are denoted by the same reference numerals and description thereof is omitted.

The tool 31 is a so-called rotary tool. As shown in FIG. 5, a rotary blade 35 such as a grindstone is attached to the tip of a rotary shaft 34 of an electric motor, and as shown in FIG. Then, the inner wall surface of the corner panel 50 is cut.

The main body 36 of the tool 31 is fixed to the tool mounting plate 32 by mounting members 37a and 37b as shown in FIG. The tool mounting plate 32 is rotatable relative to the third position adjusting plate 6d so that the tool 31 can adjust the angle of the rotary blade 35 in accordance with the corner angle of the corner panel 50 to be cut. Has become.

More specifically, the tool mounting plate 32 has elongated holes 38a and 38b provided in an arc shape.
2 is rotated in the direction J in FIG. 5, and after adjusting the angle of the rotary blade 35, the rotary blade 35 can be fixed with the binding bolts 39a and 39b. As described above, in this embodiment, even when processing corner panels having different corner angles, it is not necessary to change tools, and the processing can be performed by changing the direction of the rotary blade 35.

Further, another embodiment of the present invention shown in FIGS. 6 and 7 will be described. The basic difference between the corner panel inner wall surface cutting device 40 of this embodiment and the corner panel inner wall surface cutting device 30 described above is that, in addition to the tool 31, the tool 4 mounted in a direction substantially orthogonal to the tool 31
1 (a rotary tool similar to the tool 31).

More specifically, as shown in FIG. 7, tools 31 and 41 are mounted on both sides of the base 6a in a structure similar to that of the corner wall inner wall cutting device 30 described above. Each of the rotating blades 35 and 42 can cut two inner wall surfaces of the corner panel intersecting each other.

[0034]

According to the present invention, the inner wall surface can be cut without damaging the outer wall surface of the corner panel, and the installation space can be reduced. Further, if the V-shaped base surface of the corner panel mounting table is configured so that the opening angle can be changed, it is possible to easily adjust and machine various types of corner panels having different corner angles.
