【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、建物躯体の壁面において、仕上げ作業
（タイル直貼り等）の前に行う下処理および既存塗膜の
除去などに使用するブラスト装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a blasting device used for pretreatment on a wall surface of a building skeleton before finishing work (such as directly attaching tiles) and removal of an existing coating film. It is about.
従来この種のブラスト装置としては、実開昭63−1075
58号公報などに示されているように、研掃材を壁面へ噴

員が建物躯体の壁面へ押付けて、研掃材の壁面への吹付
け作業を行うものが一般に知られている。Conventionally, this type of blasting device has been used as the actual blasting machine 63-1075.
As shown in Japanese Patent Publication No. 58, etc., the injection port for ejecting the polishing and cleaning material to the wall surface and the suction port for sucking and collecting the polishing and cleaning material from this injection port immediately after the injection are coaxially integrated. It is generally known that an operator who rides on a gondola presses the blast injection and recovery nozzles that have been sprayed onto the wall surface of the building skeleton to spray the cleaning and cleaning material onto the wall surface.
しかし前述した従来のブラスト装置では、研掃材を噴
射して壁面への吹付けと、吹付けた後の研掃材の回収と
が同じノズル部で行われる。しかも研掃材吹付け作業
は、吸引口の周縁に設けられたリングブラシを壁面に押
付けて、研掃材がノズル部外へ飛散しないようにしなが
ら行う必要がある。However, in the above-mentioned conventional blasting device, the abrasive material is sprayed and sprayed on the wall surface, and the abrasive material after spraying is collected by the same nozzle portion. In addition, the abrasive cleaning material spraying work needs to be performed while pressing the ring brush provided on the periphery of the suction port against the wall surface to prevent the abrasive cleaning material from scattering outside the nozzle portion.
そのためノズル部を壁面へ押付けながらの研掃材吹付
け作業は、研掃材の吹付けを広い壁面に対して一度にス

物躯体の壁面へ押付けて研掃材吹付け作業を行うこと
は、研掃材を吹付ける壁面が平面であれば、比較的スム
ーズに行うことができるが、曲面等になると熟練した作
業員でも困難な作業となってしまう。Therefore, the work of spraying the abrasive cleaning material while pressing the nozzle part against the wall surface cannot be performed smoothly on the large wall surface at one time, which is troublesome and time-consuming. Staff required. In addition, pressing the nozzle part against the wall of the building frame to perform the abrasive cleaning material spraying work can be performed relatively smoothly if the wall surface onto which the abrasive cleaning material is sprayed is flat, but if curved surfaces etc. Even a worker who has done so will be a difficult task.
この発明は前述した事情に鑑みて創案されたもので、
その目的は研掃材の吹付け作業を容易に行えようにする
と共に、研掃材を吹付ける壁面が曲面の場合でも容易に
吹付け作業を行うことのできるブラスト装置を提供する
ことにある。This invention was created in view of the above-mentioned circumstances,
It is therefore an object of the present invention to provide a blasting device which facilitates the spraying work of a polishing / cleaning material and can easily perform the spraying work even when the wall surface onto which the polishing / cleaning material is sprayed is a curved surface.

ドラで覆われた広い範囲の壁面に対して容易に素早く研
掃材吹付け作業を施すことができる。As a result, the worker inside the gondola, which became a closed space, just sprays the abrasive on the wall surface from the spray nozzle.
Without worrying about the scattering of the polishing and cleaning agent outside the gondola, the polishing and cleaning agent can be reliably collected inside the gondola, making it easy and quick to cover a wide range of walls covered with the gondola. Spraying work can be performed.
また、ゴンドラの周縁が壁面に密着するので、壁面が
曲面の場合でも、平面の場合と同様に研掃材吹付け作業
を容易に素早く行えるようになる。Further, since the peripheral edge of the gondola is in close contact with the wall surface, even when the wall surface is a curved surface, it becomes possible to easily and swiftly carry out the work of spraying the abrasive cleaning material as in the case of a flat surface.
この発明のブラスト装置を使用して研掃材の吹付け作

確実に壁面３へ密着する。ゴンドラ７が壁面３へ密着す
ると、ゴンドラ７内は覆いと壁面３で囲まれた密閉空間
となる。In order to perform the spraying work of the cleaning / cleaning material 4 using the blasting device 1 having such a configuration, first, the gondola 7 is moved to a predetermined position on the wall surface 3 of the building body 2 where the spraying work is to be performed, and the contact is made closely. The mechanism 8 is operated to bring the peripheral edge of the gondola 7 into close contact with the wall surface 3. Even if the wall surface 3 is deformed such as a curved surface instead of a flat surface, the contact mechanism 8 ensures that the periphery of the gondola 7 closely contacts the wall surface 3. When the gondola 7 comes into close contact with the wall surface 3, the inside of the gondola 7 becomes a closed space surrounded by the wall surface 3 as a cover.
次に、ゴンドラ７の上層の吹付け用ブース５内におい

飛散するおそれはない。The worker 11 can perform the spraying work on the wall surface 3 in a wide range surrounded by the peripheral edge of the gondola 7 on the wall surface 3 side by a simple operation of holding and moving the injection nozzle 9. Since the periphery of the wall surface 3 on which the abrasive cleaning material 4 is sprayed is covered with the cover of the gondola 7, there is no possibility that the abrasive cleaning material 4 that has rebounded will be scattered outside the gondola 7.
なお、この吹付け作業時の作業員11は、内部に新鮮な
空気が送り込まれている専用の作業服（図示せず）を身
に付けている。The worker 11 at the time of the spraying work wears a dedicated work clothes (not shown) into which fresh air is sent.
次に、吹付け用ブース５において壁面３へ吹付けら

て集めると共に、この収集部12に接続されている回収ホ
ース13から回収タンク15へ送ることにより回収する。Next, the cleaning / cleaning material 4 that has been sprayed onto the wall surface 3 in the spraying booth 5 and dropped due to its own weight is collected by the collecting unit 12, and from the collecting hose 13 connected to this collecting unit 12 to the collecting tank 15. Collect by sending.
そして回収された研掃材４は、サンドタンク14に送ら
れ、再び供給ホース10により噴射ノズル９へ送られる。Then, the collected cleaning material 4 is sent to the sand tank 14 and again sent to the injection nozzle 9 by the supply hose 10.
所定位置の壁面３への吹付け作業が完了すると、密着
機構８の作業を停止してゴンドラ７と壁面３との密着状
態を解き、ゴンドラ７を次の位置に移動させて、その位
置で密着機構８の作動させてゴンドラ７の周縁を壁面３
へ密着させ、同様に吹付け作業を行う。これを繰り返し
て壁面３全体への吹付け作業を行う。When the spraying work on the wall surface 3 at a predetermined position is completed, the work of the contact mechanism 8 is stopped, the contact state between the gondola 7 and the wall surface 3 is released, the gondola 7 is moved to the next position, and the contact is made at that position. When the mechanism 8 is operated, the periphery of the gondola 7 is moved to the wall surface 3
And make spraying work in the same way. By repeating this, the spraying work is performed on the entire wall surface 3.
この発明は、以上のような構成からなり、次に述べる
効果を有する。The present invention has the above configuration and has the following effects.
