Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a clean booth used in factories, hospitals, etc. to clean the air in limited necessary processes or areas.

(Conventional technology) Conventionally, this type of clean booth has a steel frame with a ceiling, the surrounding area is covered with a vinyl curtain, and clean air is blown toward the floor from an air purifying unit attached to the ceiling. The interior of the clean booth is sterile and dust-free.Generally speaking, this clean booth is produced in a factory, transported by special means of transportation, and installed by workers dispatched by the manufacturer. If the frame is larger than an opening such as a door at the site, it may be difficult to transport it to the site, which is a problem, and the transportation and installation costs will be large. There were flaws.

(Problems to be solved by the invention) The present invention has been developed in view of the above-mentioned circumstances, and it allows for mixed transportation, there is no problem in transporting it to the site, and it can be easily assembled and installed by the user. The purpose is to provide a clean booth that can

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a ceiling frame formed by left and right cylindrical beams and front and rear cylindrical beams that can be divided at the center. A ceiling panel is stretched across the front and rear beams, leaving a gap in the center, and the front and rear center panels and the air purifying blower unit installed between the center panels can be removed in the gap. It is made of a cylindrical body,
A column with a shaped cutout is foldably hinged from the lower edge of one side to the lower surface of the front and rear beams at the upper end of the one side where the shaped cutout is formed. The upper end of the brace, whose lower end is hinged with a hinge attached below the hinge of the support, is attached to the lower surface of each of the front and rear divided cylindrical beams so that it can be disassembled and fixed. A height adjusting rod having an engagement groove carved in the head in a direction perpendicular to the axis, which engages with both side edges of the shaped notch, is slidably and fixably inserted into the lower end of the column, and The feature is that a vinyl curtain is provided over the frame and the support.

(Function) Since the present invention is constructed as described above, the air purifying fan unit and the front and rear pair of center panel plates are removed from the ceiling, the upper ends of the braces are removed from the front and rear beams of the ceiling frame, and the front and rear beams are removed. By splitting the ceiling from the center and folding the brace and the split ceiling into front and rear supports, it becomes large enough to be easily transported to the site, and can be packed compactly to be suitable for mixed transportation. It is. In addition, when assembling after unpacking, the front and rear columns are placed under the divided ceiling, and the head of the height adjustment rod is engraved on both sides of the notch formed from the lower edge of the column. Assemble the height adjustment rod at right angles to the support by engaging the engagement grooves provided, then raise the entire body and level the height adjustment rod. The braces and the divided ceiling are vertically supported together with the supports, and in this state, the divided ceiling and braces are opened in order, and the upper ends of the braces are attached to the corresponding front and rear divided cylindrical beams. After assembling each half of the frame as described above, connect the divided ceilings together, remove the height adjustment rods one by one and insert them into the lower ends of the columns, and attach the front and rear pairs to the center of the ceiling. Attach a center panel board and an air purifying fan unit, and finally install a vinyl curtain across the ceiling frame and pillars to create a clean booth. As described above, since the assembly work of the clean booth has been simplified, it becomes possible for the user to assemble and install the clean booth.
