Description

[Technical field]

[0001] The present invention relates to a work space protection system capable of protecting a work space and improving the airtightness of the work space. [Background technology]

[0002] Conventionally, when removing existing structures or carrying out repair or improvement work, measures have been taken to protect the work space and prevent leakage of dust, etc. Specifically, sheets were attached to the existing surface with tape, and any gaps that occurred between the sheets or between the sheet and the existing surface were sealed with tape.

[0003] In this context, for example, Patent Document 1 discloses a protective device for a dustproof sheet that separates a construction area from other areas within a building. The dustproof sheet is laid between the ceiling and floor surfaces, and a ceiling fixing material is attached to the ceiling side edge of the dustproof sheet, with height-adjustable supports provided at both ends of the ceiling fixing material.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 09-032305 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned conventional covering equipment, if the existing surface is not flat and smooth, a gap will occur between the existing surface and the dustproof sheet. Even if the gap is covered with tape, etc., depending on the environmental conditions, such as when the existing surface is wet, the covering will easily come off, making it impossible to properly cover the work space while ensuring airtightness.

[0006] For example, if the work space is inside a tunnel, the outside air may cool and cause condensation on the surface of the lining concrete. Under such environmental conditions, organic resins such as epoxy and cement-based materials are often used in reinforcement work for the lining concrete, and most of these have standards for temperature and humidity during construction. However, it is difficult to control temperature and humidity in this way using the conventional curing equipment mentioned above.

[0007] Furthermore, when the construction area is large and it is necessary to move around and cure the work space, such as in reinforcement work for lining concrete, conventional curing equipment that fixes a large number of components, such as that described in Patent Document 1, requires a lot of work to set up and remove, significantly reducing work efficiency.

[0008] In view of the above-mentioned problems, an object of the present invention is to provide a work space covering system that can cover a work space more easily and reliably than conventional systems. [Means for solving the problem]

[0009] The invention related to (1) is a protective equipment for a work space, characterized by comprising an air tube member that is pressed against an existing surface in the work space, and a protective sheet member that is connected to the air tube member and shields the work space from the outside space.

[0010] The invention related to (2) is the covering equipment for a work space described in (1) above, in which the air tube members are arranged in multiple units on the existing surface and connected to each other by bypass air hoses.

[0011] The invention related to (3) is the protective equipment for a work space described in (1) or (2) above, in which the protective sheet member is detachable from the air tube member.

[0012] The invention related to (4) is a protective equipment for a work space described in any of (1) to (3) above, wherein the protective sheet member comprises at least a corner protective sheet member connected to the air tube member and a rectangular protective sheet member connected to the corner protective sheet member.

[0013] The invention related to (5) is a covering equipment for a work space described in any one of (1) to (4) above, which includes a support member for supporting the air tube member, the support member having an extension mechanism capable of adjusting the height of the air tube member.

[0014] The invention related to (6) is a covering equipment for a work space described in any one of (1) to (4) above, which includes a support member for supporting the air tube member, the support member being an air tube support member. Effect of the Invention

[0015] According to the work space protection equipment of the present invention, it is possible to keep the work space sealed by the air tube member and the protective sheet member connected thereto. This makes it easy to control and maintain the temperature and humidity in the work space, and various construction works can be carried out in the work space without being affected by environmental conditions.

[0016] In addition, even if dust, noise, odors, or harmful substances are generated within the work space, it is possible to reliably prevent leakage of these substances. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, with reference to the drawings, an embodiment of the work space protection system of the present invention will be described, taking as an example an installation state in a tunnel. Note that the present invention is not limited to the inside of a tunnel, and can be used to protect a work space in a wide range of construction sites.

[0019] 1 is a schematic perspective view of an example of a protective equipment 100 for a work space according to an embodiment of the present invention. As shown in the figure, the protective equipment has at least an air tube member 10 that is pressed against an existing surface 50 in the work space, and a protective sheet member 20 that is connected to the air tube member 10 and that shields the work space from the outside space.

[0020] Furthermore, in the illustrated embodiment, a plurality of support members 30 for supporting the air tube member 10 are installed on the handrail of the work floor 40 of the aerial work vehicle. In other words, the air tube member 10, which has excellent flexibility and adhesion, can be pressed against the existing surface 50, so that no gap is generated between the air tube member 10 and the existing surface 50.

[0021] This eliminates the need for sealing with tape as in the past, and eliminates peeling of the sealing due to condensation, etc. In addition, even if the existing surface 50 has a curved surface, such as the lining concrete of a tunnel, it becomes possible to press the air tube member 10 against the existing surface 50 without any gaps.

[0022] As shown in FIG. 1, a support member 30 is provided to support the air tube member 10, and an extension mechanism is provided to adjust the height of the air tube member 10. In this way, by configuring the support member 30 to be extendable with a simple structure, it becomes easy to adjust the height of the work floor 40, i.e., the distance between the work floor 40 and the existing surface 50. In addition, by making the support member 30 extendable when moving the work space, it becomes possible to move and reinstall the air tube member 10 efficiently in a short time without damaging the air tube member 10 or the existing surface 50. In addition, in the above-mentioned extension mechanism, the inner tube and the outer tube may be configured to be insertable and detachable, and various other known mechanisms can be applied.

[0023] Next, Fig. 2 shows a cross-sectional view of the air tube member 10 in this embodiment, and Fig. 3 shows a side view of the air tube member 10. As shown in the figures, the air tube member 10 has a double structure made up of an outer skin 10a and an inner bag 10b that is housed inside the outer skin 10a with an inner bag insertion fastener 13 opened.

[0024] In this embodiment, the outer cover 10a is made of polyvinyl chloride and the inner bag 10b is made of polyurethane, but the materials are not limited to these and may be any materials having the necessary strength and flexibility. Also, the air tube member 10 does not necessarily have to have a double structure.

[0025] Air is then sealed in the inner bag 10b via the air valve 14, resulting in an elastic air tube member 10. The above-described double structure makes it possible to replace the inner bag 10b, and furthermore, the inner bag 10b can be protected by the outer skin 10a. In addition, when not in use, the air can be released and the bag can be folded, so storage space can be reduced.

[0026] The outer skin 10a is provided with a curing sheet member mounting fastener 12 for connecting the curing sheet member 20, and further, a cushioning material 11 is attached to the portion of the outer skin 10a that contacts the existing surface 50.

[0027] In this embodiment, a sponge made of a material such as polyurethane foam or polyester is provided as the cushion material 11. This effectively prevents the existing surface 50 from being damaged by the air tube member 10, and further improves the pressing performance with the existing surface 50. However, the cushion material 11 is not essential.

[0028] The air tube member 10 of this embodiment has a basic linear shape with an outer diameter of 150 mm and a length of 3000 mm, but is not necessarily limited to these dimensions and shape. In other words, the shape, dimensions, etc. can be appropriately changed depending on the shape of the existing surface 50 to which the air tube member 10 is pressed.

[0029] For example, if the existing surface 50 has a curved surface with a small radius, by manufacturing the air tube member 10 in a shape that corresponds to the curved surface, it is possible to reliably prevent gaps from occurring between the air tube member 10 and the existing surface 50.

[0030] Depending on the size of the work space, multiple air tube members 10 can be connected and installed on the existing surface 50. In this embodiment, as shown in Fig. 3, connecting fasteners 15 (e.g., hook-and-loop fasteners) are provided near both ends of the air tube members 10, and adjacent air tube members 10 can be connected together by bands, elbows, or the like (not shown) that can be coupled to the connecting fasteners 15.

[0031] Next, Fig. 4 and Fig. 5 show side views of an example of a curing system 100 for a work space inside a tunnel. Fig. 6 shows an enlarged view of the installation of the air tube member 10 shown in Fig. 4. As shown in the figures, a plurality of air tube members 10 are connected and installed on an existing surface 50 (illustrated lining concrete), and each of the air tube members 10 has the necessary dimensions and shape according to the size of the work space and the shape of the existing surface 50.

[0032] The above-mentioned curing sheet member 20 is connected to the air tube member 10 placed on the existing surface 50. Fig. 7 shows the connection mode of the curing sheet member 20. As shown in the figure, when the air tube member 10 is placed in a curved or diagonal shape, it is difficult to attach the rectangular curing sheet member 20a. Therefore, in the illustrated embodiment, a corner curing sheet member 20b processed according to the placement mode of the air tube member 10 is connected to the air tube member 10.

[0033] The corner curing sheet member 20b and the rectangular curing sheet member 20a are provided with curing sheet member connecting fasteners 21 that enable them to be connected to each other. This makes it possible to easily connect the curing sheet members 20 to each other.

[0034] Furthermore, by dividing the protective sheet member 20 into the corner protective sheet member 20b and the rectangular protective sheet member 20a as described above, it is possible to increase the versatility of the rectangular protective sheet member 20a, and it becomes possible to reuse it when protectively covering other work spaces.

[0035] The lower end of the protective sheet member 20 may be connected to the work floor 40, or to ensure greater airtightness, the protective sheet member 20 can be laid on the floor surface of the work floor 40 and connected to the laid protective sheet member 20 with a fastener (not shown).

[0036] 8 is a schematic plan view showing an example of how air is supplied to the air tube members 10. As shown in the figure, a plurality of air tube members 10 are connected by a bypass air hose 16 via an air valve 14. One end and the other end of the connected plurality of air tube members 10 are connected by an air hose 18 to a branch valve 19, which is then connected to an air supply unit 17.

[0037] The air supply unit 17 includes at least an air generating means 171 for generating air, and a pressure control means 172 for sending the generated air at an appropriate pressure to the air tube member 10. As shown in the figure, a pressure measuring air hose 191 is connected between the air hose 18 and the pressure control means 172 in order to perform appropriate pressure control.

[0038] A blower or a compressor can be used as the air generating means 171. It is also possible to provide a plurality of air supply units 17 and divide a plurality of air tube members 10 to perform air supply and pressure control.

[0039] The above describes one embodiment of the present invention. According to the work space protection equipment of the present invention, the air tube member 10 and the protection sheet member 20 connected thereto can effectively maintain the work space in an airtight state.

[0040] This makes it easier to control and maintain the temperature and humidity in the work space, and various construction works can be carried out in the work space without being affected by environmental conditions. For example, it is possible to eliminate problems such as condensation in the work space, and ensure the required construction quality.

[0041] In addition, the air tube member 10 of the present invention can easily change shape due to its cushioning properties. Therefore, the air tube member 10 can be pressed against the existing surface 50 without any gaps, following the shape and surface properties of the existing surface 50.

[0042] In addition, by appropriately controlling the air pressure of the air tube member 10, the air tube member 10 can appropriately absorb the oscillation and vibration of the work floor 40 transmitted through the support member 30 while maintaining adhesion to the wall surface, effectively preventing the occurrence of gaps and damage to the existing surface 50.

[0043] (Another embodiment) Although one embodiment of the present invention has been described above, the present invention is not necessarily limited to the above-described embodiment.

[0044] For example, Figures 1 and 9 show an example of using a high-altitude work vehicle, and Figures 3 and 4 show an example of a large vehicle with a multi-stage work platform 40 on its loading platform, but the present invention is not necessarily limited to these. The curing equipment of the present invention can be applied in any construction site in order to provide a work space between the existing surface 50 and the equipment.

[0045] In the above-mentioned embodiment, the curing equipment is provided on the lining concrete inside a tunnel. However, the curing equipment of the present invention is not limited to the inside of a tunnel, but can be applied to a wide range of structures such as the top plate and side walls of a box culvert, the wall surface and ceiling slab of a building, etc.

[0046] 9, a part or the whole of the support member 30 of the air tube member 10 can be an air tube support member 30a. By configuring it in this way, it becomes easy to press the air tube member 10 onto the existing surface 50, and it is possible to reduce the labor required.

[0047] In addition, as a method for detachably joining the protective sheet member 20 to the air tube member 10, it is preferable to use a protective sheet member mounting fastener 12 in order to improve workability, but this is not necessarily limited to this, and it is also possible to apply a detachable joining method using a fastener that opens and closes with a slider, a fastener that uses a fitting, a clip, a button, a buckle, adhesive tape, joining with a hole and a string, etc.

[0048] In addition, it is preferable for each fastener, the inner bag insertion fastener 13, the connecting fastener 15, and the protective sheet member connecting fastener 21, to be a hook-and-loop fastener in order to improve workability, but this is not necessarily limited to this, and it is also possible to apply a method similar to the method of detachably joining the protective sheet member 20 to the air tube member 10.

[0049] The scope of the present invention is defined by the claims, not by the description of each embodiment above, and includes all modifications within the meaning and scope of the claims. The specific materials, dimensions, shapes, etc. described in the above embodiments can be modified within the scope of the present invention. [Explanation of symbols]
