Description

  The present invention relates to a seat setting device and a seat setting method.

  As a concrete structure, for example, when a tunnel or the like is constructed, a centle may be used as a concrete casting form (see, for example, Patent Document 1).

Japanese Patent No. 4444097

  The centle has a pair of foldable mold members (also referred to as “lower cat parts”) on both ends. In concrete cast using a center (for example, secondary lining concrete of a tunnel), surface bubbles are easily generated in the concrete on the casting surface of the formwork member. In order to suppress the surface bubbles, there is a case where the concrete is driven after the sheet member is placed on the casting surface of the mold member (the sheet member sticking surface in the mold).

  In this case, it is conceivable that the sheet member is manually installed in a state in which the formwork member is folded before the centle is built after the cleaning operation of the removed centle. However, under the folded formwork member, the work is difficult because the sheet member is installed on the upper side. However, the space for the installation work is limited, and it is difficult to increase the number of people who perform the installation work. Further, when there is unevenness on the ground below the folded formwork member, the seat member is likely to swing due to unevenness of the ground in the installation work. For this reason, wrinkles are likely to occur in the sheet member, and there may be a problem that installation work takes time.

  Then, the subject of this invention aims at providing the sheet | seat installation apparatus and sheet | seat installation method which become easy to install a sheet | seat member with respect to a formwork.

  In order to solve the above-mentioned problems, a sheet installation apparatus according to the present invention is a sheet installation apparatus used for installing a sheet member on a concrete casting form, and has a long rail portion. A main body having a guide part that is detachably attached to the mold along the axial direction of the mold or the longitudinal direction of the mold, and a roll support that rotatably supports the roll around which the sheet member is wound. And a movement support portion guided by the rail portion and supporting the main body portion, and the roll support portion is a mold in which the axial direction of the roll is a direction substantially orthogonal to the longitudinal direction of the rail portion. A roll is supported so that it may become a direction substantially parallel with the sticking surface of the sheet | seat member in a frame.

  In this sheet setting device, the roll is supported by the main body so that the axial direction of the roll is a direction substantially perpendicular to the longitudinal direction of the rail portion and is substantially parallel to the pasting surface. . Therefore, when the sheet member is pulled out from the roll, the sheet member is pulled out along the longitudinal direction of the rail portion with at least the inclination of the sheet member with respect to the sticking surface in the axial direction of the roll being suppressed. Moreover, the movement support part which supports a main-body part is guided by the rail part in the direction in alignment with the axial direction of a formwork, or the longitudinal direction of a formwork. Therefore, the main body can be moved in the axial direction of the mold or in the direction along the longitudinal direction of the mold. Therefore, for example, the sheet member pulled out from the roll is moved along the pasting surface while moving the main body part in the axial direction of the mold or in the longitudinal direction of the mold, so that the drawn sheet member can be continuously formed. It becomes easy to install in.

  In the sheet installation apparatus, the mold frame may be a curved surface, and the pasting surface may be a predetermined contact surface that is in contact with the curved surface of the mold frame. In this case, since the roll is supported by the main body so as to be in a direction substantially parallel to the predetermined contact surface as the pasting surface even when the formwork forms a curved surface, the sheet member with respect to the pasting surface It becomes easy to suppress the inclination. The formwork may be a flat surface.

  In the sheet installation apparatus, the rail portion includes the first rail arranged on one side of the pasting surface so as to be along the axial direction of the mold or the longitudinal direction of the mold, and the axial direction of the mold or the longitudinal of the mold A second rail disposed on the other side of the affixing surface along the direction, and the movement support portion is a first pulley portion guided by the first rail and a second rail guided by the second rail. It is preferable that the first pulley portion supports the main body portion on one side, and the second pulley portion supports the main body portion on the other side. In this case, since the first rail and the second rail are arranged so as to sandwich the pasting surface, the pasting surface and the main body part face each other through the space between the first rail and the second rail. Thereby, the sheet | seat member pulled out from the roll can be easily installed in a formwork through the space between a 1st rail and a 2nd rail.

  In the sheet installation apparatus, the guide unit preferably includes a plurality of fixing jigs that can be attached to and detached from the formwork, and an adjustment unit that is provided on each of the fixing jigs and supports the rail unit. In this case, the extending direction of the rail portion can be easily adjusted by a plurality of fixing jigs. Moreover, the length from a fixing jig to a rail part etc. can be adjusted with an adjustment part. Thereby, the attitude | position of a main-body part can be adjusted.

  Specifically, the fixing jig may be a magnet jig having a switch for switching between attachment and detachment with respect to the mold as a configuration that favorably exhibits the above-described effects. In this case, the fixing jig can be easily attached to and detached from the mold.

  Specifically, the adjustment unit may be a universal joint as a configuration that preferably exhibits the above-described effects. For example, when the adjustment unit supports the rail unit on the lower side of the adjustment unit, the rail unit is suspended along the vertical direction by gravity. In this way, the posture of the main body can be automatically adjusted using gravity.

  In said sheet | seat installation apparatus, a main-body part may further have a guide member extended in the direction substantially parallel to the axial direction of a roll between a sticking surface and a roll support part. In this case, when the sheet member pulled out from the roll is guided by the guide member, tension is applied to the sheet member by the guide member. Thereby, when installing a sheet | seat member in a formwork, it becomes difficult to wrinkle a sheet | seat member.

  The above-described sheet setting device may further include a roller portion that presses the sheet member pulled out from the roll against the formwork. In this case, the manual pressing of the sheet member can be omitted.

  The sheet installation device may further include an injection device that injects an adhesive onto the sheet member pulled out from the roll. In this case, even a sheet member having no adhesive can be easily attached.

  Further, the present invention can also be understood as an invention of a sheet installation method for installing a sheet member on a concrete placement mold, and this sheet installation method is a sheet for a concrete placement mold. A sheet installation method for installing a member, a guide unit having a long rail part, a movement support part guided by the rail part, and a roll support part that rotatably supports a roll around which the sheet member is wound. A preparatory step for preparing the main body, and a guide unit that is detachably attached to the mold and is attached along the axial direction of the mold or the longitudinal direction of the mold, and the main body is mounted by the movement support unit. Supporting the roll so that the supporting main body installation step and the axial direction of the roll are in a direction substantially perpendicular to the longitudinal direction of the rail portion and substantially parallel to the surface of the sheet member on the formwork. In comprising a roll installation step of supporting the roll, pull the sheet member from the roll, the sheet placing step of placing the sheet member is pulled out against the mold, the.

  According to such a sheet installation method, in the roll installation step, the axial direction of the roll is a direction substantially orthogonal to the longitudinal direction of the rail portion and is a direction substantially parallel to the pasting surface, The roll is supported by the roll support section. Therefore, when the sheet member is pulled out from the roll, the sheet member is pulled out along the longitudinal direction of the rail portion with at least the inclination of the sheet member with respect to the sticking surface in the axial direction of the roll being suppressed. In the main body installation step, the guide portion is detachably attached to the mold and the rail portion is attached so as to be along the axial direction of the mold or the longitudinal direction of the mold, and the main body is supported by the movement support portion. Therefore, the main body can be moved in the axial direction of the mold or in the direction along the longitudinal direction of the mold. Therefore, for example, by performing the sheet installation process while moving the main body in the axial direction of the mold or in the direction along the longitudinal direction of the mold, it becomes easy to continuously install the drawn sheet members on the mold. .

  ADVANTAGE OF THE INVENTION According to this invention, the sheet | seat installation apparatus and sheet | seat installation method which become easy to install a sheet | seat member with respect to a formwork can be provided.

Note that in the description, the same elements or elements having the same function may be denoted by the same reference numerals, and redundant description will be omitted.

  First, an outline of a centle to which the seat setting device and the seat setting method according to the present embodiment are applied will be described. FIG. 1 is a cross-sectional view illustrating a centle to which a sheet setting device and a sheet setting method are applied. FIG. 2 is a schematic view showing a state in which the form member of the centle shown in FIG. 1 is folded.

  Tunnel lining concrete is a concrete structure constructed in a placement space in a tunnel. A tunnel is formed by excavating a part of natural ground in the tunnel axis direction. As shown in FIG. 1, the tunnel 50 includes an inner wall surface 50 s on which tunnel lining concrete 51 is constructed. Further, inside the tunnel 50, a centle (form frame) 60 for constructing the tunnel lining concrete 51 is installed. The center 60 is made of steel, for example. When installed in the tunnel 50, the center 60 has an outer peripheral surface 60s whose extending direction is the tunnel axis direction.

  The inner wall surface 50s is formed by spraying mortar on a ground excavation surface after a support and a wire net are installed. Further, the inner wall surface 50s may be supported in an arch shape when a lock bolt is driven into a natural ground. Thus, the inner wall surface 50s is formed by a NATM (New Austrian Tunneling Method) method or the like. Invert concrete G is constructed at the lower part of the inner wall surface 50s, and the lower part of the inner wall surface 50s is formed flat or with a large curvature.

  The center 60 is installed on the invert concrete G. The center 60 extends within the tunnel 50 by a predetermined length in the tunnel axis direction. The center 60 is formed in an arch shape along the inner wall surface 50s of the tunnel 50 so that the outer peripheral surface 60s of the center 60 and the inner wall surface 50s of the tunnel 50 face each other. A lattice-shaped frame 53 is assembled inside the center 60, and the center 60 is supported on the invert concrete G by the frame 53.

  The tunnel lining concrete 51 is sequentially constructed in accordance with the progress of excavation. The tunnel lining concrete 51 is sequentially constructed in units of blocks, for example, with the length of the centle 60 in the tunnel axis direction being one block.

  An injection hole 54 for placing concrete C into the top end space 52 </ b> A of the placement space 52 is provided at the top of the center 60. Further, a plurality of input holes (not shown) for placing concrete C in the lower space 52B of the placement space 52 excluding the top end space 52A are provided on the side of the center 60. The injection hole 54 and the injection hole are formed so as to penetrate from the inside of the center 60 to the outer peripheral surface 60 s of the center 60 in the thickness direction. The crown portion of the tunnel lining concrete 51 is constructed by the concrete C cast from the injection hole 54 into the top end space 52A. Further, the side portion of the tunnel lining concrete 51 is constructed by the concrete C placed from the charging hole 23 into the lower space 52B.

  As shown in FIG. 2, the center 60 includes a plurality of curved formwork members 61 and 62. The plurality of formwork members 61 and 62 are arranged along the inner wall surface 50 s of the tunnel 50. The mold member 61 is disposed so as to face the upper side of the inner wall surface 50 s of the tunnel 50. The formwork member 62 is disposed on both ends of the formwork member 61. The casting surface (curved surface) 63 of the mold member 62 has a curved surface with the central axis L1 as an axis. The central axis L1 corresponds to the central axis of the arc when the placement surface 63 is regarded as an arc surface, and extends in a direction substantially parallel to the tunnel axis direction. Since the center 60 extends in a predetermined length along the tunnel axis direction, the placement surface 63 of the mold member 62 corresponds to a part of a cylindrical surface with the central axis L1 as an axis. The mold member 62 extends a predetermined length with the direction of the central axis L1 as a longitudinal direction. That is, the direction of the central axis L1 of the placement surface 63 and the longitudinal direction of the formwork member 62 coincide with each other.

  The mold member 62 is rotatably connected to the mold member 61 at a location adjacent to the mold member 61. The mold member 62 is connected to a jack (not shown) provided on the frame 53. The formwork member 62 can be folded with respect to the formwork member 61 by this jack.

  Here, for example, in order to suppress generation of surface bubbles in the concrete C on the placement surface 63 of the mold member 62, a sheet member may be installed on the placement surface 63 of the mold member 62. In this case, since the sheet member is installed in a state in which the mold member 62 is folded, it is necessary to install the sheet member upward with respect to the placing surface 63 facing downward.

  Next, a configuration of the seat setting device according to the embodiment will be described. FIG. 3 is a side view of the seat setting apparatus 1 according to the embodiment. FIG. 4 is a cross-sectional view of the seat setting device 1 taken along line IV-IV in FIG.

  As shown in FIGS. 3 and 4, the sheet setting device 1 is used for setting the sheet member S with respect to the mold member 62 of the center 60. The sheet member S is mounted on the sheet setting device 1 while being wound around the roll R, and is pulled out from the roll R when being set on the formwork member 62. The sheet setting device 1 is configured such that the drawn sheet member S can be continuously set on the formwork member 62. That is, in the sheet setting device 1, the positional relationship between the sheet member S pulled out from the roll R and the attachment surface 64 (hereinafter also simply referred to as “attachment surface 64”) of the sheet member S in the formwork member 62 is approximately. The roll R is configured so as to be in a parallel positional relationship, and the roll R is in the axial direction (center axis L1 direction) of the placing surface 63 of the mold member 62 or the mold frame while maintaining this positional relationship. The member 62 is configured to be movable in the longitudinal direction.

  The affixing surface 64 is a contact surface that contacts the placement surface 63 at the center in the width direction of the placement surface 63 (a direction orthogonal to the axial direction of the placement surface 63) (see FIG. 4). “The sheet member S (or the central axis L2 of the roll R) and the pasting surface 64 are substantially parallel” includes not only the state in which the sheet member S (or the central axis L2) is parallel to the pasting surface 64, but also the sheet member. A state in which S (or central axis L2) is inclined within a predetermined angle range from a state parallel to sticking surface 64 is also included. Within the predetermined angle range, even if the sheet member S in an inclined state with respect to the pasting surface 64 is installed on the formwork member 62, the range of inclination angles is such that wrinkles are not generated in the sheet member S.

  3 to 5 show an orthogonal coordinate system. The X direction of the orthogonal coordinate system indicates the direction of the center axis L1 of the placement surface 63, and the Y direction is a direction substantially orthogonal to the direction of the center axis L1 and is attached to the attachment surface 64 of the sheet member S in the mold member 62. The Z direction indicates a direction substantially orthogonal to the central axis L1 direction and a direction substantially orthogonal to the attachment surface 64 of the sheet member S in the mold member 62.

  The sheet setting device 1 includes a guide unit 10 that is detachably attached to the center 60, a movement support unit 20 guided by the guide unit 10, and a main body unit that is supported by the movement support unit 20 and supports the roll R. 30.

  The guide unit 10 includes a fixing jig 11, an adjustment unit 12 provided in each of the fixing jigs 11, and a long rail unit 13 (first rail 14 and second rail 15) supported by the adjustment unit 12. And having. The fixing jig 11 is a magnet jig as an example, and is attachable to and detachable from the steel centle 60. The fixing jig 11 preferably has a switch for switching attachment / detachment with respect to the centre 60 in order to facilitate attachment / detachment of the fixing jig 11 with respect to the centle 60. In the following description, “first rail 14 and second rail 15” may be abbreviated as “rail portion 13” unless it is particularly necessary to distinguish between “first rail 14 and second rail 15”. .

  For example, a plurality of fixing jigs 11 are provided for the first rail 14 and a plurality of fixing jigs 11 are provided for the second rail 15. At least one fixing jig 11 is provided on each end of the first rail 14 in the longitudinal direction. At least one fixing jig 11 is provided on each end in the longitudinal direction of the second rail 15. Therefore, the extending direction of the first rail 14 can be adjusted by adjusting the mounting position of the plurality of fixing jigs 11 on the first rail 14 with respect to the centle 60. Similarly, the extending direction of the second rail 15 can be adjusted by adjusting the mounting position of the plurality of fixing jigs 11 on the second rail 15 with respect to the centle 60.

  The guide portion 10 is attached to the centle 60 so as to be along the direction of the central axis L1 of the placement surface 63. In the guide portion 10, the fixing jig 11 is attached to the center 60 so that the longitudinal direction L <b> 3 of the rail portion 13 is along the central axis L <b> 1 direction of the placement surface 63. Specifically, the fixing jig 11 is attached to the center 60 with the longitudinal direction of the first rail 14 being along the direction of the central axis L <b> 1 of the placement surface 63. Similarly, the fixing jig 11 is attached to the center 60 in a state where the longitudinal direction of the second rail 15 is along the direction of the central axis L <b> 1 of the placing surface 63.

It is a universal joint. The connection part 12a and the connection part 12c are, for example, metal bars. The lengths of the connecting portion 12a and the connecting portion 12c can be adjusted. Thereby, the length from the fixing jig 11 to the rail part 13 can be adjusted, and the attitude | position of the main-body part 30 can be adjusted. The joint portion 12b is a universal joint that can freely change the angle at which the connection portion 12a and the connection portion 12c that sandwich the joint portion 12b are joined. As the joint portion 12b, for example, one using a cross shape or a sphere can be employed.

Specifically, the connection part 12c is suspended below the fixing jig 11 and the connection part 12a via the joint part 12b in the direction of gravity (the vertical direction in FIG. 4). Therefore, for example, even if the attachment position and the angle of the fixing jig 11 with respect to the centle 60 change, the direction of the connecting portion 12c automatically changes in a direction along the lower side in the gravity direction due to gravity.

  The rail part 13 prescribes | regulates the direction which guides the movement support part 20 to the longitudinal direction L3. The rail portion 13 includes a long first rail 14 and a long second rail 15. The first rail 14 is disposed on one side 64 a of the pasting surface 64.

The suspended portion 21c extends to the outside of the first rail 14 through the groove 14d of the first rail 14, and has a length such that the first rail 14 and the main body 30 do not interfere with each other. That is, the 1st pulley part 21 is supporting the main-body part 30 on the one side 64a side.

  The second pulley portion 22 includes a pair of wheels 22a, a shaft 22b that rotatably supports each wheel 22a, and a suspended portion 22c that extends from the axial center of the shaft 22b so as to be orthogonal to the shaft 22b.

That is, the second pulley portion 22 supports the main body portion 30 on the other 64b side.

  The main body 30 is a structural body that supports the roll R, and is a frame body made of, for example, a steel pipe. The main body 30 includes cross members 31, 32, a guide member 33 spanning the cross members 31, 32, a pair of vertical members 34, 35 fixed at both ends of the guide member 33, and a guide member 33 And a roll support portion 36 that spans the longitudinal members 34 and 35 so as to be substantially parallel. The cross members 31 and 32 and the guide member 33 are fastened by, for example, an orthogonal clamp. The guide member 33 and the vertical members 34 and 35 are fastened with, for example, a universal clamp. The vertical members 34 and 35 and the roll support portion 36 are fastened by, for example, a universal clamp.

  The cross members 31 and 32 are, for example, round pipes, and are arranged substantially parallel to each other with a larger distance than the width of the sheet member S. Suspended portions 21c of the plurality of first pulley portions 21 are joined to the cross member 31 so as to extend in the same direction (radial direction). Suspended portions 22c of the plurality of second pulley portions 22 are joined to the cross member 32 so as to extend in the same direction (radial direction).

Configured to be movable. That is, the cross members 31 and 32 extend along the longitudinal direction L3 of the rail portion 13.

  The guide member 33 is bridged so as to be orthogonal to the cross members 31 and 32 at a substantially central portion of the cross members 31 and 32. The guide member 33 is, for example, a round pipe. The guide member 33 guides the sheet member S drawn from the roll R so as to change its longitudinal direction. At this time, for example, the sheet member S pulled out from the roll R comes into sliding contact with the guide member 33. As a result, the guide member 33 applies tension to the sheet member S. The surface of the sheet member S that is in sliding contact with the guide member 33 may be the front surface (the surface that is affixed to the mold member 62), or the back surface (the surface opposite to the surface that is affixed to the mold member 62). There may be. In the present embodiment, the surface of the sheet member S is in sliding contact with the guide member 33.

The vertical members 34 and 35 are, for example, square pipes.

  The roll support part 36 supports the roll R so as to be rotatable around the central axis L2. The roll support portion 36 is bridged so as to be substantially parallel to the guide member 33 on the opposite side of the vertical members 34 and 35 from the fixed portion with the guide member 33. The roll support part 36 is, for example, a round pipe.

  Since the guide member 33 is substantially orthogonal to the cross members 31 and 32 and the guide member 33 and the roll support portion 36 are substantially parallel, the roll support portion 36 is substantially orthogonal to the cross members 31 and 32. Therefore, when the first pulley portion 21 is disposed in the first rail 14 and the second pulley portion 22 is disposed in the second rail 15, the roll support portion 36 is arranged in the longitudinal direction L <b> 3 of the rail portion 13. It will extend in a substantially orthogonal direction.

  The roller unit 40 presses the sheet member S drawn from the roll R against the formwork member 62. The roller unit 40 includes a base 41 spanned between the cross members 31 and 32, an arm 42 supported by the base 41 so as to be swingable, and a roller 43 supported rotatably on the distal end side of the arm 42. Have. The base 41 swings the arm 42 so as to rotate about the Y direction. The base 41 urges the arm 42 to the side opposite to the cross members 31 and 32 by a spring or the like, for example. Therefore, the roller 43 is urged toward the mold member 62 via the arm 42. In addition, in FIG. 4, illustration of the base 41 and the arm 42 is abbreviate | omitted.

  The spray device 45 sprays an adhesive onto the sheet member S drawn from the roll R. The injection device 45 is stretched over the cross members 31 and 32 so as to face the guide member 33. In this embodiment, the adhesive is not previously applied to the sheet member S wound around the roll R. Therefore, the injection device 45 injects an adhesive onto the surface of the sheet member S guided by the guide member 33. The injection device 45 may inject the adhesive using, for example, an air source (not shown) as power.

  In the seat setting device 1 configured as described above, the first pulley portion 21 is disposed in the first rail 14 and the second pulley portion 22 is disposed in the second rail 15, whereby the guide member 33. Will extend in the direction along the width direction of the placement surface 63 of the mold member 62. Here, the guide member 33 extends in a direction substantially parallel to the attaching surface 64 by adjusting the lengths of the connecting portion 12a and the connecting portion 12c of the adjusting portion 12 and adjusting the posture of the main body portion 30. can do. At this time, since the roll support part 36 is substantially parallel to the guide member 33, the central axis L2 direction of the roll R is a direction substantially orthogonal to the longitudinal direction L3 and is substantially parallel to the pasting surface 64. The roll R is supported so as to be in the direction.

  Further, the guide member 33 extends in a direction substantially parallel to the direction of the central axis L <b> 2 of the roll R between the sticking surface 64 and the roll support portion 36. Therefore, the width direction of the sheet member S guided by the guide member 33 is along a direction substantially parallel to the central axis L2 direction of the roll R (that is, a direction substantially parallel to the pasting surface 64).

  Next, a sheet setting method executed using the sheet setting apparatus 1 will be described with reference to FIG. FIG. 5 is a flowchart illustrating a sheet setting method executed using the sheet setting apparatus 1.

  In this sheet installation method, first, a guide part 10 having a long rail part 13, a movement support part 20 guided by the rail part 13, and a roll R around which the sheet member S is wound are rotatably supported. A preparation step for preparing the main body 30 having the roll support portion 36 to be performed is executed (S1).

  Subsequently, the guide unit 10 is detachably attached to the center 60, and the rail unit 13 is attached so as to be along the central axis L1 direction of the placement surface 63, and the main body installation step of supporting the main body unit 30 by the moving support unit 20 is performed. Is executed (S2). In the example of FIG. 4, the fixing jig 11 is attached to the side surface of the end portion of the mold member 61 on the one side 64 a, and the first rail 14 is suspended by the fixing jig 11 via the adjustment unit 12. On the other 64b side, the fixing jig 11 is attached to the end surface of the mold member 62, and the second rail 15 is suspended by the fixing jig 11 via the adjusting portion 12. The first pulley portion 21 is disposed inside the first rail 14, and the second pulley portion 22 is disposed inside the second rail 15. The main body portion 30 is supported by the first pulley portion 21 and the second pulley portion 22. As a result, the main body 30 can be moved along the longitudinal direction L3 of the rail 13.

  Subsequently, the central axis L2 direction of the roll R is a direction substantially orthogonal to the longitudinal direction L3 of the rail portion 13 and is a direction substantially parallel to the attachment surface 64 of the sheet member S in the mold member 62. Thus, the roll installation process which supports the roll R with the roll support part 36 is performed (S3). Subsequently, a sheet installation process is performed in which the sheet member S is pulled out from the roll R and the extracted sheet member S is installed on the formwork member 62 (S4).

  As described above, according to the sheet setting device 1 and the sheet setting method executed in the sheet setting device 1, the direction of the central axis L2 of the roll R is substantially perpendicular to the longitudinal direction L3 of the rail portion 13. Thus, the roll R is supported by the roll support portion 36 of the main body 30 so as to be in a direction substantially parallel to the attachment surface 64 of the sheet member S in the mold member 62. Therefore, when the sheet member S is pulled out from the roll R, the sheet member S is extended along the longitudinal direction L3 of the rail portion 13 in a state in which the inclination of the sheet member S with respect to the affixing surface 64 at least in the central axis L2 direction of the roll R is suppressed. Is pulled out. Further, the movement support portion 20 that supports the main body portion 30 is guided by the rail portion 13 in a direction along the central axis L1 direction of the placement surface 63 of the mold member 62. Therefore, the main body 30 can move in the direction along the center axis L1 direction of the placement surface 63. Therefore, for example, the sheet member S pulled out from the roll R is moved along the affixing surface 64 while moving the main body 30 in the direction along the central axis L1 direction of the placing surface 63. It becomes easy to install in the formwork member 62.

  In the present embodiment, the main body portion 30 is suspended from the guide portion 10 via the movement support portion 20. That is, the seat setting apparatus 1 is not directly grounded to the ground (for example, invert concrete G). Therefore, even if there is unevenness on the ground below the formwork member 62, the sheet member S is prevented from swinging due to unevenness on the ground. As a result, the sheet member S is less likely to be wrinkled.

  In the present embodiment, the mold member 62 has a curved surface. The affixing surface 64 is a contact surface that contacts the placement surface 63 at the center in the width direction of the placement surface 63 (a direction orthogonal to the axial direction of the placement surface 63). Thereby, even if the formwork member 62 forms a curved surface, the roll R is supported by the main body 30 so as to be in a direction substantially parallel to the contact surface as the pasting surface 64. It becomes easy to suppress the inclination of the sheet member S with respect to 64.

  In the present embodiment, the rail portion 13 is arranged in the direction of the center axis L1 of the placement surface 63 and the first rail 14 disposed on the one 64a side of the affixing surface 64 along the direction of the center axis L1 of the placement surface 63. 2nd rail 15 arrange | positioned on the other 64b side of the sticking surface 64 so that it may follow. The movement support unit 20 includes a first pulley unit 21 guided by the first rail 14 and a second pulley unit 22 guided by the second rail 15. The first pulley portion 21 supports the main body portion 30 on one side 64a, and the second pulley portion 22 supports the main body portion 30 on the other 64b side. Thereby, since the 1st rail 14 and the 2nd rail 15 are arrange | positioned so that the sticking surface 64 may be pinched | interposed, the formwork member 62 and the main-body part 30 via the space between the 1st rail 14 and the 2nd rail 15 are arranged. And oppose each other. As a result, the sheet member S pulled out from the roll R can be easily installed on the mold member 62 through the space between the first rail 14 and the second rail 15.

  In the present embodiment, the guide unit 10 includes a plurality of fixing jigs 11 that can be attached to and detached from the center 60, and an adjustment unit 12 that is provided on each of the fixing jigs 11 and supports the rail unit 13. Thereby, the extending direction of the rail portion 13 can be easily adjusted by the plurality of fixing jigs 11. Further, the length or the like from the fixing jig 11 to the rail portion 13 can be adjusted by the adjusting portion 12. As a result, the posture of the main body 30 can be adjusted.

  In the present embodiment, the fixing jig 11 is a magnet jig having a switch for switching attachment / detachment with respect to the center 60. Thereby, attachment and detachment of the fixing jig 11 with respect to the center 60 becomes easy.

  In the present embodiment, the adjustment unit 12 is a universal joint. When the adjustment unit 12 supports the rail unit 13 on the lower side of the adjustment unit 12, the rail unit 13 is suspended along the vertical direction by gravity. In this way, the posture of the main body 30 can be automatically adjusted using gravity.

  In the present embodiment, the main body 30 further includes a guide member 33 extending in a direction substantially parallel to the direction of the central axis L <b> 2 of the roll R between the sticking surface 64 and the roll support part 36. Thereby, when the sheet member S pulled out from the roll R is guided to the guide member 33, tension is applied to the sheet member S by the guide member 33. As a result, when the sheet member S is installed on the formwork member 62, the sheet member S is hardly wrinkled.

  In this embodiment, the roller part 40 which presses the sheet | seat member S pulled out from the roll R with respect to the formwork member 62 is further provided. Thereby, the manpower which presses the sheet | seat member S can be saved.

  In this embodiment, the injection apparatus 45 which injects an adhesive agent with respect to the sheet | seat member S pulled out from the roll R is further provided. Thereby, even if it is the sheet member S which does not have an adhesive agent, it can affix easily.

In the example of FIG. 6, it is assumed that an adhesive is applied in advance to the sheet member S wound around the roll R. In the sheet setting device 1A, the injection device 45 is omitted.

  The bed 37 is a support member that supports the worker P in the main body 30 in order to perform the installation work of the sheet member S with the worker P lying on the back. The bed 37 is a flat plate member that is long in the height direction of the worker P, for example. For example, the bed 37 is supported by vertical members at its four corners. In the example of FIG. 6, the bed 37 is supported by the vertical member 34 </ b> A at both ends in the longitudinal direction on one side 64 a of the affixing surface 64. The vertical member 34A is tightly coupled to both ends in the longitudinal direction of the horizontal member 31A. The cross member 31A is different from the cross member 31 in that it has a length corresponding to the height of the worker P. Also in such a sheet setting apparatus 1A, the same sheet setting method as the above-described sheet setting method can be executed.

  Also in the sheet setting apparatus 1A and the sheet setting method executed in the sheet setting apparatus 1A, the sheet member S pulled out from the roll R is moved while moving the main body 30A in the direction along the central axis L1 direction of the placing surface 63. The operator P can easily place the drawn sheet member S on the formwork member 62 continuously along the sticking surface 64.
