Description

  The present invention relates to a decompression curing method that enables efficient renewal construction of a commercial space while minimizing the influence on operations of a commercial facility.

  In recent years, with the diversification of customer needs, the diversification of products, the diversification of lifestyles and customs, and the spread of information dissemination, the products and services that customers demand in the short term and seasonally change. In addition, with recent changes in the economic environment, there is a tendency for companies and stores to be replaced and product contents to be replaced frequently.

  In such a product replacement work, that is, a renewal work, the goods are usually displayed around the space where the work is performed. For this reason, although the construction itself can be performed at night without burdening the customer, it is necessary to prevent dust, dust, dust, etc. generated during construction from affecting the product. For this reason, at the time of renewal construction of commercial spaces, construction has been carried out in which panels are continuously arranged along the construction space to separate the construction space from the commercial space.

  FIG. 6 schematically shows a commercial floor 200 to which a conventional renewal construction method is applied. In the conventional renewal construction method, in the environment where the product 204 is placed in the commercial floor 200, the section to be renewed is separated by the temporary enclosure device 202, the commercial space 201 is separated, and the waste generated in the section to be renewed, Construction is carried out while curing so that dust and dirt do not contaminate merchandise 204 such as clothing. The temporary enclosure device 202 holds a plurality of panels 203a and 203b from the back with a support material such as a pipe, and separates a section for renewal construction extending from the ceiling to the floor from the commercial space. Also, near the entrance where workers enter the renovation section, dust and dust generated by the construction may be easily scattered. Separate the area around the entrance from the ceiling to the floor with a vinyl sheet 205 or the like. It was necessary to carry out a separate curing work.

  In the above-mentioned prior art documents, the height of the bracket and temporary enclosure for fixing the panel for installing the temporary enclosure to the space to be constructed is reused regardless of the ceiling height of the space to be renewed. Is possible. However, when a dedicated bracket is made for a panel used for temporary enclosure, there is a problem that it is too expensive and the flexibility of selection of construction materials is impaired because it is not versatile for the panel. . In addition, if the type of panel is not questioned, in recent years, the panel size types are also abundant, so it is more expensive to make the panel itself stretchable, and the configuration itself becomes complicated, so the panel itself is complicated. Durability is also reduced and it cannot be said that efficient construction is always possible.

  Further, in Japanese Patent Application Laid-Open No. 2004-150190 (Patent Document 1), when renewal construction is performed, a boundary provided with a partition and a doorway with temporary curing materials is provided between the renovation work section and the business area. A dust spill prevention system is described that can prevent airborne dust from flowing into the business area by providing air vents and detecting the presence and direction of wind flowing through the vents and controlling the operation of the dust collector. . In Patent Document 1, the outflow of dust is controlled by detecting the direction of the air flowing through the vent hole formed between the renewal work section and the business area and controlling the number of dust collectors activated.

  Even in the system described in Patent Document 1, it is possible to perform the renewal construction without causing floating dust to flow out during the renewal construction. However, it takes time and effort to install and remove the curing material to form the boundary, such as panel installation and support material installation / removal, and to control the dust collector by detecting the air flow rate. Since a separate control device is required, there is a problem that it takes time and labor for installation and management, and the cost also increases. For this reason, the dust outflow prevention system described in Patent Document 1 cannot cope with a situation in which strict cost requirements and shortened delivery times are required for renewal construction.

JP 2004-150190 A

  In view of the problems of the conventional technology, the present invention further enables a short-term construction for the renewal construction of a commercial facility, and enables efficient renewal construction by preventing the outflow of dust to the commercial space. The purpose is to provide a renewal construction method.

  The present invention has been made to solve the above problems, and the present inventor has conceived of applying a so-called clean booth when performing renewal construction in order to solve the above problems. In general, a clean booth is capable of working while ensuring cleanliness in the clean booth by blowing clean air into a positive pressure and exhausting the air from the clean booth to the outside. It is. The clean booth itself is set to a positive pressure inside so that suspended dust from the outside does not enter the clean booth. This means that, if the inside of the clean booth is set to a negative pressure, the floating dust generated in the clean booth does not flow out of the clean booth.

  In addition, when the clean booth is set to a negative pressure, a filter device or the like for blowing purified air into the clean booth is not required, so it is only necessary to use a plastic sheet for constituting the clean booth. Since the sheet itself is lightweight, a temporary enclosure can be efficiently configured by temporarily fixing the ceiling to the ceiling with a stapler or a tucker without using a metal support material or the like.

  In the present invention, the space to be renovated is surrounded by a plastic sheet extending from the ceiling to the floor, and a dust collector that exhausts normal air toward the commercial space is installed in the opening formed in the plastic sheet to perform the renewal construction. By maintaining the space at a negative pressure relative to the commercial space and performing the renovation space under the negative pressure environment, the construction period can be shortened and the cost can be reduced while preventing floating dust from flowing out. The reduced pressure curing method can be provided.

The schematic of the commercial floor 100 to which the decompression curing method of this invention is applied is shown. The figure which shows the installation method of the clean booth 106 used for the decompression curing method of this invention. The figure which shows the construction aspect which temporarily fixes the sheet | seat 106b for walls from the ceiling 110. FIG. The figure which shows the aspect installed temporarily by attaching the sheet | seat 106c for walls which has the entrance / exit 113 to the ceiling 110. FIG.

The figure which shows schematically the commercial floor 200 where the conventional renewal construction method is given.

  Hereinafter, the present invention will be described with embodiments, but the present invention is not limited to the embodiments described below. FIG. 1 shows a schematic diagram of a commercial floor 100 to which the reduced pressure curing method of the present invention is applied. A commercial floor 101 shown in FIG. 1 is formed with a commercial space 101 in which a product 104 such as clothing and food, a fitting room 105 and the like are installed, and a space 102 in which a product layout and interior renovation work is performed. Yes. Renewal construction is performed in a space 102 defined in a clean booth 106. The term “clean booth” in the present embodiment is for imparting a function of maintaining external cleanliness, and uses the inside as a negative pressure with respect to the outside. An opening 112 for installing the dust collector 108 is formed at an appropriate location of the clean booth 106, and the dust collector 108 is installed in the opening 112 with airtightness. A plurality of openings 107 are formed in the plastic sheet temporarily fixed to the ceiling 110 of the clean booth 106, and the air in the commercial space 101 can be allowed to flow in corresponding to the air discharged by the dust collector 108. ing.

  The clean booth 106 has an entrance and exit, and an adhesive dustproof mat 109 and the like are laid on the floor of the entrance and exit to prevent the dust 103 from being taken out. As indicated by an arrow A, the dust collector 108 allows the air in the commercial space 101 to flow into the clean booth 106 from the ceiling 110, the entrance / exit, and other openings necessary for construction. The dust collector 108 also cleans the air by removing the dust 103 with a filter (not shown) attached to the dust collector 108 as indicated by the arrow B. The purified air is discharged to an appropriate location in the commercial space 101 as indicated by the arrow C again.

  For this reason, the inside of the space 102 is set to a negative pressure relative to the commercial space 101, and the floating dust can be prevented from flowing out. The clean booth 106 can also be used for semiconductor equipment or medical equipment, but in the present invention, it is not necessary to send normal air into the space 102 for renewal construction and From the viewpoint of efficiency and cost reduction, on-site construction of a ceiling sheet with a plurality of openings 107 formed in a size suitable for the space 102 and a wall sheet that can be suspended from the ceiling 110 to the floor with a margin It is preferable that the ceiling 110 or an appropriate structure or floor of the ceiling 110 be temporarily fixed with a stapler or a tacker.

The plastic sheet is not particularly limited, but a vinyl sheet used in a vinyl house can be used. The dust collector 108 has an intake capacity of 45 m ³ / min depending on the volume of the construction space. A general-purpose type dust collector equipped with a pre-filter / HEPA filter of a certain degree can be used, especially if the particle size of floating dust in the exhaust can be in the range of about 0.1 μm to about 7 μm, etc. There is no limitation. A plurality of dust collectors 108 may be installed according to the volume of the space 102 to be constructed. In addition, since the cleanliness of the air discharged from the dust collector 108 is generally discharged in a state improved compared to the cleanliness that the consumer travels, there is no influence on the commercial space 101.

  Airtightness between the plastic sheet and the dust collector 108 is not necessary in a strict sense, and it is sufficient that floating dust does not flow out due to pressure fluctuations such as the entry / exit of workers and the shaking of the vinyl sheet. It is only necessary to keep an eye on the boundary between the clean booth 106 and the dust collector 108 with other adhesive sheets such as gummed tape.

  FIG. 2 shows a method for installing the clean booth 106 used in the reduced pressure curing method of the present invention. First, a sized ceiling sheet 106a having sufficient space is prepared in consideration of the size of the space 102 to be constructed, and openings 107 having an appropriate interval and number are formed, and temporarily fixed to the ceiling 110 with a stapler or a tacker. go. At this time, if there is an appropriate structure on the ceiling 110, the ceiling sheet 106a can be temporarily fixed using the structure, and a gypsum board or interior material constituting the ceiling 110 as shown in FIG. The ceiling sheet 106a can also be temporarily fixed directly. Even when the ceiling sheet 106a is temporarily temporarily fixed to the ceiling 110, the inside of the clean booth 106 is set to a negative pressure, so that the inflow of air into the opening 107 is not hindered.

  FIG. 3 shows a construction mode in which the wall sheet 106 b is temporarily fixed from the ceiling 110. An opening 112 is formed in the wall sheet 106b, and a dust collector 108 (not shown) can be installed. The floor surface of the wall sheet 106b can be temporarily fixed with a stapler or a tucker when the floor material is also renewed. Also, when reusing the flooring as it is, as shown in FIG. 3, to prevent the flooring from being damaged, a horizontally long temporary fixing weight 111 or a magic tape that can be fixed to the flooring and the plastic sheet with double-sided tape (registered) (Trademark) can be temporarily fixed by installing it at the boundary of the space 102 using the vertical margin of the wall sheet 106b.

  FIG. 4 shows a mode in which a wall sheet 106 c having an entrance 113 is further temporarily installed on the ceiling 110. Similarly to the wall sheet 106b, the lower side of the wall sheet 106c can be temporarily fixed to the flooring. In addition, it is possible to separately use a sheet in which a chain used for a clean room or the like is wrapped and fixed at the lower part of the sheet forming the entrance / exit 113, and the entrance / exit sheet is double or triple cut. It can be set as the structure which prevents the outflow of floating dust by changing the position of this and providing and providing a space | interval. Furthermore, a magic tape (registered trademark) can be attached to the contact between the sheet for the entrance / exit 113 in the vertical direction and the floor, and the floating dust can be prevented from flowing out to the outside.

  FIG. 5 shows a state in which the wall boots 106b to 106e are installed in four directions and the clean booth 106 is completed. A dustproof mat 109 formed of an adhesive sheet is disposed on the floor surface of the doorway 113 to prevent dust from being taken out through the shoe sole. In addition, a dust collector 108 is installed in the opening 112, and airtightness is provided by appropriate sealing means, so that floating dust does not flow out between the commercial space 101 and the space 102 for renovation work. Due to 108, the inside of the clean booth 106 has a negative pressure with respect to the commercial space 101.

  In the clean booth 106 shown in FIG. 5, since the ceiling sheet 106a and the wall sheet 106b are only temporarily fixed, the removal work can be performed quickly and efficiently, and the materials to be discarded are mainly plastic. Since it is only a sheet, it is not necessary to arrange large-scale curing materials such as support materials and panels, and efficient construction is possible.

  In addition, if you want to prevent fear and renewal contents from being known by the consumer through the plastic sheet, you can keep the plastic sheet smoke type, and from the bright commercial space 101, Can be kept out of sight. Further, it is possible to construct a conventional temporary enclosure along the space 102 where renewal construction is performed according to construction contents and specific requirements, and install and install a clean booth 106 shown in FIG.

  In other embodiments, the wall sheets 106b, 106c, 106d, and 106e may be formed separately, and the four corners may be temporarily fixed with gum tape or the like to provide airtightness, or the wall sheets 106b, 106c, and 106d may be provided. , 106e can be cut as a continuous sheet at the site, and an appropriate position can be determined and construction for the opening 112 and the entrance / exit 113 and temporary fixing can be performed.

  As described above, according to the present invention, the reduced pressure curing method that can be installed easily and quickly, is easy to remove, and does not cause dust generated in the renewal construction to flow out to the commercial space 101 while minimizing the generation of waste materials. Can be provided.
