リートパネルの表面加工装置に関するものである。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight cellular concrete panel surface processing apparatus for forming a dense layer on the surface of a lightweight cellular concrete panel housed in a formwork. It is.

ブ養生して製造されるものである。Recently, there has been a tendency to increase the number of industrialized houses built by the curtain wall method, the unity method, etc. In such industrialized houses, lightweight cellular concrete panels called PALC and ALC are sometimes used as outer wall materials. This lightweight cellular concrete panel is manufactured by pouring a concrete slurry containing bubbles into a formwork, leaving the concrete panel to stand for a predetermined period of time, curing the concrete, removing the concrete panel, and curing the concrete panel in an autoclave.

生後にパネル表面に塗装を行うが、パネル表面の近傍に
気泡があると、塗装が斑となつてしまう。In the production of the lightweight cellular concrete panel, after a predetermined time has elapsed after the concrete slurry has been poured into the mold, the surface of the concrete in the mold rises, and bubbles accumulate near the concrete surface. If the concrete surface rises, the panel will not fit properly when attaching the panel to the skeleton, and if bubbles accumulate near the concrete surface, carbon dioxide gas in the outside air will enter the panel through these bubbles and neutralize the concrete. Inconvenience that it is made to occur. Further, after autoclaving, the surface of the panel is painted. If there are air bubbles near the surface of the panel, the painting will be spotty.

締作業を行っている。さらに、ローラ圧縮後、模様ロー
ラによりパネル表面に模様をつける。In order to solve these inconveniences, it is necessary to flatten the concrete surface and crush the air bubbles near the concrete surface to form a dense solid layer. When the worker has a hardness of, the worker performs a roller pressing operation of rolling a large-diameter roller having a diameter of 500 mm or more on the surface of the concrete panel. Further, after the roller is compressed, a pattern is formed on the panel surface by a pattern roller.

ル表面を平らに均すこともできない。However, in the conventional example in which the roller is rolled on the concrete panel surface, the pressing force of the roller on the panel surface is weak,
There is a problem that it is not possible to sufficiently form a dense layer by crushing bubbles near the panel surface. Further, in the conventional example, if the concrete is too hard, even if the panel surface is rolled with a roller, the panel surface cannot be pressed and the panel surface cannot be leveled.

One end of this ball screw 12 is connected to a motor 13 that can rotate forward and reverse, and the other end is a bearing.
It is pivoted on 14. Here, the cart 10, the nut member
A moving mechanism 15 for reciprocating the lightweight cellular concrete panel 2 in a direction perpendicular to the round bars 3 and 4 from the ball screw 12, the motor 13 and the bearing 14 is configured. In addition, moving mechanism
According to 15, the moving speed of the lightweight cellular concrete panel 2 is configured to be smaller than the peripheral speed of the round bars 3 and 4.

る。That is, the two round steel rotation motors 6 of the rotation drive mechanism 9 are used.
When the motor 13 of the moving mechanism 15 is rotated forward while the first and second round bars 3 and 4 are rotating clockwise in FIG. 10 moves to the left in FIG. Then, as shown in FIG. 3, the round bar 3 (4) forcibly rotating applies a pressing force F to the lower left near the panel surface. Since the pressing force F is as small as 10 to 500 mm in diameter of the round bars 3 and 4, the ground pressure is large, and the pressing force F works in combination with the large contact angle of the round bars 3 and 4 with the panel surface. The direction approaches the vertical direction. Therefore, the vertical direction components F 1 of the pressing force F is increased with respect to the horizontal direction component F 2, the panel surface in this state rubbed. Then, the bubbles near the panel surface are crushed, and the surface of the panel 2 becomes smooth like a mirror finish.

A roller 16 having a large diameter and being rotatably or rotatably supported on the upper portion thereof is brought into contact with the upper portion, and the roller 16 is mounted on the bases 5, 7 via a bearing 17 and a mounting member (not shown). Therefore, since the peripheral surface of the round bar 3 is brought into contact with the roller 16, the round bar 3 is prevented from being pressed by the lightweight cellular concrete panel and deformed.

トパネル２の移動速度を正確に制御できる。According to this embodiment, the panel 2 was moved by the moving mechanism 15 while the round steel members 3 and 4 whose peripheral surfaces were in contact with the surface of the lightweight cellular concrete panel 2 were forcibly rotated by the rotation drive mechanism 9. Therefore, the panel surface is rubbed in a state where a large vertical pressing force is applied near the surface of the panel 2 and the panel 2 is rubbed.
A dense layer can be formed on the surface of Therefore, the carbon dioxide gas in the outside air can be prevented from entering the panel 2 by the solid layer, and the effect of suppressing carbonation of concrete can be improved. Further, since the surface of the panel 2 is finished like a mirror surface, the operation of pressing the panel surface with the pattern roller, which is conventionally required, can be omitted. Moreover, since a large pressing force is exerted near the panel surface by the round bars 3 and 4, the surface processing of the panel 2 can be performed even when the concrete is somewhat hardened. Further, in the present embodiment, since the two round bars 3 and 4 are respectively driven to rotate by the round bar rotation motor 6, the dense layer can be formed more effectively. In particular, since the two round bars 3 and 4 are arranged in parallel and at different levels, first the surface of the lightweight cellular concrete panel is smoothed with the upper round bar 3 and then with the lower round bar 4 The surface of the lightweight cellular concrete panel can be further smoothed. Further, the moving mechanism 15 is connected to the carriage 10, the nut member 11, the ball screw
Since it is composed of the motor 12 and the motor 13, the moving speed of the lightweight cellular concrete panel 2 can be accurately controlled.
