Description

  The present invention relates to an apparatus and method for covering a wall such as a concrete wall under repair for blinding.

  When repairing a concrete wall surface of a tunnel such as a subway, there is a period in which the reinforcing bars are exposed on the wall surface after the existing housing is struck until the concrete is sprayed again. In particular, if left in this state at a subway station, the exposed steel bars could be seen from the platform, making it look unsightly and sometimes annoying subway users.

  Therefore, conventionally, in order to hide the repaired part, multiple sheets for covering the repaired part are prepared, and anchors for fixing the sheet are provided on the upper part of the tunnel hunch part and the lower part of the floor part. The person used the scaffold to install and remove the seat every time.

  Conventionally, in a store or the like, a roll-type sheet winder is used to conceal the interior of a user or the like from a plurality of sheets adjacent to each other (see, for example, Patent Document 1).

JP 2008-163726 A

  However, subway tunnel repair work can only be done in a short time from the last train to the first train, and it takes a long time to install and remove the seat, so the number of days required for the repair work becomes longer, or There was a problem of requiring many workers.

The schematic front view of the wall surface coating apparatus which concerns on embodiment of this invention. The upper part conceptual side view of a wall surface coating apparatus.

  A wall surface coating apparatus 100 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

  The wall surface coating apparatus 100 is an apparatus for covering and covering the repair wall surface when the concrete wall surface A such as a railway underground structure is repaired and preventing it from being visually recognized from the surroundings. Here, the case where the wall surface coating apparatus 100 is used when repairing the concrete wall surface A of a subway station will be described.

  However, the wall surface covering device 100 is not limited to those used in railway stations or tunnels such as subways, and is, for example, an underground structure such as a tunnel on a motorway where a person can visually recognize the wall surface. It may be used for this. In particular, railway users often view the tunnel wall surface from a platform or the like when waiting for the train, and the necessity of hiding the repaired portion from the viewpoint of appearance is high, so the effectiveness of the wall surface coating apparatus 100 is high.

  Furthermore, the wall surface covering device 100 is not limited to the one used in the underground structure with the ceiling part covered, and is used in the structure in which the upper part is not completely covered and at least a part is open. It may be a thing.

  The repair wall covering apparatus 100 has a sheet 11 that can cover the repair wall, a winding member 12 that is connected to an upper portion of the sheet 11 and can wind the sheet 11 in a roll shape, and can rotate the winding member 12. And a plurality of sheet winders (winding machines) 10 each having a supporting member 13 supported on the same. A commercially available sheet winder 10 can be used.

  The material of the sheet 11 is not limited as long as it is opaque so that the covered repair wall surface is not visible from the front, and is not damaged easily even if it is rubbed against the repair wall surface.

  Here, the sheet 11 has a rectangular shape, and one end of the sheet 11 is fixed to the winding member 12. Although not shown, it is preferable that the both sides and the lower end of the sheet 11 are folded to form folded portions so that the strength is improved.

  Here, the winding member 12 is a cylindrical member, and is rotatably supported by a round bar-like support member 13 inserted through the inside. Although not shown, the winding member 12 includes an engaged portion that can be engaged with and can be released from the engaging portion provided at the distal end of the long handle. As a result, an operator or the like standing on the track surface of the station can easily feed and wind the sheet 11 by rotating the winding member 12 without using a scaffold by operating the handle. It becomes.

  And the supporting member 13 is equipped with the fixing | fixed part 14 fixed to the anchor etc. which were fixed to the concrete wall surface A at the both ends. The fixing portion 14 is located outside from both ends of the winding member 12. Although the fixing portion 14 is not illustrated, for example, it has a box shape, and a through hole is formed in a fixing surface with the concrete wall surface A. An anchor which is the fixing portion 14 is inserted into the through hole, and this is fastened by a nut. Anything can be used.

  In FIG. 1, for simplification, there are three sheet winders 10, but the number of sheet winders 10 depends on the length of the concrete wall A in the repair range that needs to be blindfolded. Or what is necessary is just to determine according to the length of the concrete wall surface A which a subway user can visually recognize from a platform.

  An engaged tool 15 is attached to the lower part of the sheet 11. The engaged tool 15 is, for example, an annular metal fitting, and engages with an engaging tool 21 such as a hook provided at the lower part of the concrete wall surface A or at the rear part of the track surface. Due to the engagement between the engaged tool 15 and the engaging tool 21, it is possible to prevent the seat 11 from being turned up by wind pressure or the like when the train passes. The engaged tool 15 corresponds to the locked means of the present invention, and the engaging tool 21 corresponds to the locked means of the present invention.

  When such a wall surface coating apparatus 100 is used, an operator or the like can easily feed and wind the sheet 11 by operating the sheet winder 10, and the repaired wall surface is hidden as compared with the conventional one. Therefore, it is possible to reduce the time required for the repair work, so that sufficient time for substantial repair work can be secured.

  When the installation height of each sheet winder 10 is the same, a gap is generated between the fed sheets 11 in order to avoid interference with the support member 13 of the adjacent sheet winder 10. However, in this case, the repair wall surface is visually recognized by the subway user from the gap, and the blindfold function is not sufficiently performed. Therefore, in order to eliminate such a problem, it is necessary to prevent a gap generated between the sheets 11 from being generated.

  Therefore, it is necessary that the left and right side edges of the sheets 11 overlap each other or the left and right side edges of the sheets 11 are adjacent to each other so that no gap is generated between the adjacent sheets 11. is there.

  In order to prevent the support member 13 from interfering, the installation heights of the adjacent sheet winders 10 are made different, and the positions of the sheet winders 10 in the front-rear direction (direction from the tunnel wall surface to the platform) are made different. It is necessary to let That is, in the sheet winder 10 attached adjacent to the width direction of the sheet 11 (the extending direction of the track, the left-right direction in FIG. 1), the installation position of the support member 12 is shifted in the vertical direction and the front-rear direction. Thereby, the adjacent sheets 11 are also displaced in the front-rear direction, and it is easy to make the side end portions overlap in the lateral direction.

  Specifically, the support member 12 of the sheet winder 10 has an inclined surface B that is inclined upward toward the front side (the platform side, the left side direction in FIG. 2) existing on the upper portion of the concrete wall surface A such as a haunch portion. ,is set up. Accordingly, the sheet winder 10A positioned relatively above is relatively on the front side (front), and the sheet winder 10B positioned relatively below is relatively on the back side (rear). It will be.

  Here, the support members 12 of the sheet winders 10A and 10B are the same, but the support members 12 of the sheet winders 10A and 10B may be different. Thereby, even if the support member 12 is installed on the vertical concrete wall surface A or the ceiling surface instead of the inclined surface B, the installation positions of the sheet winders 10A and 10B can be shifted in the vertical direction and the front-rear direction. . Moreover, the sheet winder 10 may be installed at three or more different positions in the up-down direction or the front-rear direction.

  Further, in the adjacent sheet winder 10, the winding direction is relatively upward, that is, in the sheet winder 10 </ b> A positioned relatively forward, the sheet 11 is fed out behind the winding member 13. In the sheet winder 10B positioned relatively downward, that is, relatively rearward so as to perform winding, the sheet 11 is unwound and wound on the rear side of the winding member 13. It is preferable to determine the winding direction of the sheet 11 in the take-up member 12. Thereby, the gap | interval of the front-back direction of the adjacent sheet | seat 11 can be made small, and it becomes possible to suppress effectively that a repair wall surface is seen from the gap | interval of the sheet | seat 11. FIG.

  In this case, in the sheet winder 10A positioned relatively upward, when the sheet is fed, the winding member 12 is rotated counterclockwise as shown by a solid line arrow in FIG. In the sheet winder 10B positioned below, when the sheet 11 is fed, the winding member 12 may be rotated clockwise as indicated by the dotted arrow in FIG. The rotation direction of 13 is the opposite direction.

  Furthermore, the wall surface coating apparatus 100 is configured to prevent the seat 11 from being turned over from the side portion or the lower portion due to wind pressure from a passing train or the like so that the repair wall surface can be seen. It is preferable to provide a regulation means 22 for regulating movement.

  Here, as the restricting means 22, a rope 22 positioned in front of the plurality of sheets 11 is stretched across the sheet 11 in the transverse direction. Both ends of the rope 22 are fixed using a fixture 23 such as an anchor provided on the concrete wall surface A. And it is preferable that there are multiple ropes 22. Further, instead of the rope 22, a band or a band-like net may be used.

  Conventionally, when the sheet 11 is installed, the entire sheet 11 is sometimes covered with a net. However, in this embodiment, a roll-type sheet winder 11 is used, and it is physically impossible to wind the sheet 11 and the net at the same time in consideration of wind pressure strength and the like. Further, if the entire sheet 11 is covered with a net, the effect of shortening the working time is not achieved. The inventor has confirmed that the same turning prevention effect as that obtained when the entire sheet 11 is covered with a net is obtained by stretching a plurality of ropes.

  However, instead of passing with the rope 22 or the like so as to cross the plurality of sheets 11, the turning may be suppressed with the rope 22 or the like for each sheet 11.

  Furthermore, it is preferable that the wall surface coating apparatus 100 includes the separation suppressing unit 24 in order to prevent the adjacent sheets 11 from separating and generating a gap therebetween. Here, the separation suppressing means 24 has a through hole 11a formed in the side end portion of each sheet 11, and is a binding tool 24 such as a rope or metal fitting that is inserted through the through holes 11a of adjacent sheets 11 and bound together. is there.

  And the wall surface coating method which concerns on embodiment of this invention is the wall surface coating apparatus which consists of the several sheet winder 10 with which the supporting member 12 slip | deviates to the up-down direction and the front-back direction, and is attached to the concrete wall surface A as mentioned above. 100.

  In this method, each of the sheets 11 of the plurality of sheet take-up machines 10 is fed out, and each of the engaged tools 15 is engaged with the engaging tool 21 so that the repair surface is covered with the plurality of sheets 11. .

  Note that the present invention is not limited to the wall surface coating apparatus 100 specifically described in the above-described embodiment and a method using the same, and may be appropriately changed within the scope described in the claims. Can do.
