  It is an object of the present invention to provide a temporary roof comprising a plurality of rows of arch-shaped annular bodies that can be expanded and contracted by supplying and discharging air, and to or under the space under the temporary roof. It is to provide a temporary roof that enables direct unloading or unloading from the building.

  The temporary roof which concerns on this invention is equipped with the cyclic | annular body which curves and extends in the arch shape of the several row | line | column which touches mutually. Each row of annular bodies is composed of a plurality of segments that are in contact with each other in the direction of extension and that can be expanded and contracted by supplying and discharging fluid. A plurality of segments of the annular body in each row are releasably connected to each other, and each segment of the annular body in one row and each segment of the annular body in the other row adjacent to the annular body in the one row are They are releasably connected.

  According to the present invention, the plurality of rows of annular bodies are in an expanded state by supplying a fluid such as air to the individual segments constituting them, and are temporarily set by the plurality of rows of annular bodies in the expanded state. A roof is constructed. The temporary roof can be installed, for example, on a plurality of pillars that form a building frame of a building under construction.

  The temporary roof can be assembled on the ground by connecting a plurality of segments to each other to form a plurality of rows of annular bodies and supplying a fluid to each segment. The temporary roof assembled on the ground can be lifted on, for example, a housing of a building under construction and installed on the housing. During the use of the temporary roof installed on the frame, one of a plurality of segments constituting the temporary roof or a plurality of segments adjacent to each other is disconnected from the other segments. Can be removed. However, the removal of the one or more segments is performed so that the structure as the temporary roof is maintained by the remaining segments. Thereby, an opening can be provided in the temporary roof, and the load can be directly suspended in the space under the temporary roof being installed through the opening, and the load can be directly lifted from the space. The opening provided in the temporary roof can be closed by returning the removed one or more segments to their original positions and connecting them to the other segments, whereby the temporary roof is in its original state. Can be restored.

  Each segment is a bag defining the fluid receiving space, and is formed on a pair of end faces facing each other in the extending direction of the annular body, a pair of side faces facing each other in the arrangement direction of the annular body, both end faces, and both side faces. A bag having continuous inner and outer peripheral surfaces, four plate members respectively attached to both end surfaces and both side surfaces of the bag, and attached to the outer peripheral surface of the bag along the both end surfaces and both side surfaces One piece of both pieces constituting the line fastener or the hook-and-loop fastener extending respectively may be provided.

It is a perspective view of a temporary roof. FIG. 6 is a perspective view of a temporary roof with two segments removed. It is a side view of a temporary roof. It is a side view which shows the support aspect of a temporary roof. It is a perspective view of a segment. It is a perspective view of the segment of the folded state.

  Referring to FIG. 1, a temporary roof 10 is installed on two pairs (four) of pillars C that are in the process of building upward from a floor slab F that forms a building frame of a building under construction. The temporary roof 10 temporarily covers an area (working area) where work such as bar arrangement, concrete placement, etc. is performed, and functions to block rain, snowfall, direct sunlight and the like on the working area.

  The temporary roof 10 includes a plurality of rows (four rows in the illustrated example) of annular bodies 12 that are curved and extend in an arch shape, and the plurality of rows of annular bodies 12 are in contact with each other in the arrangement direction a. The plurality of rows of annular bodies 12 have the same outer shape, that is, the same cross-sectional shape, and the same length (length in the extension direction) with respect to the extension direction b of these annular bodies 12. In addition, the arch shape which is the curved shape of the annular body 12 is an arc in the illustrated example. The number of rows of the annular bodies 12, the degree of curvature (in the illustrated example, the degree of curvature of the arc), the size (thickness) and length (length in the extension direction or circumferential length) of the cross section are as follows: 10 can be arbitrarily determined in consideration of the width of the work area covered by the work 10, the height required for the work, and the like. In addition, the said arch shape which is the curved shape of the annular body 12 can be made into a parabola, an elliptic arc, etc. instead of the example of illustration, for example.

  Each row of annular bodies 12 is composed of a plurality (five in the illustrated example) of segments 14 that can be expanded and contracted by supplying and discharging a fluid such as air. The plurality of segments 14 curved and extending in the same direction (extension direction b) as the annular bodies 12 in each row have the same cross-sectional shape as the annular bodies 12. These segments 14 have the same outer shape, and therefore the length (width) of the annular body 12 in the arrangement direction a and the length of the annular body 12 in the extension direction b (length in the extension direction or circumferential length) are the same. . Further, these segments are in contact with each other in the extending direction b of the annular body 12, and a plurality of segments 14 constituting the annular body 12 in one row and the annular body 12 in the other row adjacent to the one row are connected. The plurality of constituent segments 14 are opposed to and in contact with each other in the arrangement direction a of the annular body 12.

  The plurality of rows of annular bodies 12 may have non-identical cross-sectional shapes instead of the illustrated example in which they have the same cross-sectional shape. For example, an annular body 12 in one row and an annular body 12 in another row adjacent to each other, and therefore, each segment 14 constituting the annular body 12 in the first row and the annular body 12 in the other row are constituted. Each segment 14 may have a different length dimension, that is, a different width dimension with respect to the arrangement direction a.

  Moreover, about the some segment 14 which comprises the cyclic | annular body 12 of each row | line | column, it can replace with the example of illustration in which these have equal circumferential direction length, and shall have different circumferential direction length. Therefore, the quantity of the plurality of segments 14 constituting the one row and the quantity of the plurality of segments 14 constituting the annular body 12 of the other row can be made different from each other.

  The plurality of segments 14 constituting each row of annular bodies 12 are releasably connected to each other, whereby the annular body 12 is formed. In addition, each segment 14 of the annular body 12 in one row and each segment 14 of the annular body 12 in the other row facing and in contact with the segment in the arrangement direction a of the annular body 12 can be released from each other. It is connected. Thereby, the annular bodies 12 are connected to each other.

  By releasing the connection between the adjacent segments 14, one or a plurality of segments 14 can be removed from the temporary roof 10, and an opening 16 (FIG. 2) can be provided in the temporary roof 10. As shown in FIG. 2, of the four rows of annular bodies 12, two segments 14 facing the arrangement direction a are removed from the two rows of annular bodies 12 located in the center in the arrangement direction a of the annular bodies 12. It is.

  The opening 16 formed by removing the two segments 14 can be used for loading or unloading any load (not shown) including building materials through the openings. More specifically, unloading onto the floor slab F under the temporary roof 10 or unloading from the floor slab can be performed using a heavy machine such as a tower crane. According to this, it is possible to eliminate the conventional work of carrying the load once on the floor slab F under the temporary roof 10 or carrying it out under the temporary roof 10.

  The temporary roof 10 is supported by two pairs of pillars C at both ends in the extension direction b of the two rows of annular bodies 12 located at both ends in the arrangement direction a of the four rows of annular bodies 12 constituting the temporary roof. . For this reason, each pair of columns C receives the action of the horizontal component W1 and the action of the vertical component W2 of its own weight W (FIG. 3) of the temporary roof 10. Here, in order to prevent warping of each pair of columns C due to the action of the horizontal direction component W <b> 1, both ends 12 a in the extending direction b of each annular body 12 are preferably connected by wires 18.

  For installation on the two pairs of columns C of the temporary roof 10, as an example, a lid-like member 20 (FIG. 4) covering a plurality of main bars C <b> 1 protruding from each column C upward in the axial direction of the column. It is used.

  As shown in FIG. 4, the lid-like member 20 includes a flat cylindrical body 22 whose upper end is closed, and an axial direction of the cylindrical body 22 which is spaced from the closed upper end of the cylindrical body inside the cylindrical body. And a plurality of protrusions 24 extending to the surface. The plurality of protrusions 24 receive the main bars C1 of the column C between them, so that the lid-like member 20 is substantially immovable in the horizontal direction with respect to the column C. The two annular bodies 12 mounted on the two pairs of pillars C are released to the cylindrical body 22 of the lid-like member 20 via the surface fastener 25 similar to the surface fastener 40 described later at each end 12a. It is fixed as possible. In the illustrated example, one of the two pieces of the hook-and-loop fastener 25 and the other piece are respectively attached to each end 12a of the annular body 12 and the cylindrical body 22 of the lid-like member 20, The two pieces are in contact with each other on the hook surface and the loop surface. Instead of the illustrated example, each end 12a of the annular body 12 is fixed to the cylindrical body 22 of the lid-like member 20, so that the annular body 12 and the lid-like member 20 are integrated. . Reference sign C2 indicates a hoop line surrounding the plurality of main bars C1 of the column C.

  Referring to FIG. 5, an example of the segment 14 is shown. The segment 14 includes a bag 26 that defines a receiving space for the fluid. The bag 26 is made of, for example, a waterproof cloth, and includes a pair of end faces 28a and 28b facing each other with respect to the extending direction b of the annular body 12 and a pair of side surfaces 30a and 30b facing each other with respect to the arrangement direction a of the annular body 12. The inner circumferential surface 32a and the outer circumferential surface 32b face each other and are continuous with the both end surfaces 28a, 28b and the both side surfaces 30a, 30b and define the inner circumferential surface and the outer circumferential surface of the annular body 12, respectively.

  The segment 14 is also attached to both end faces 28a, 28b and both side faces 30a, 30b of the bag 26, extends along these faces, and covers these faces, for example, two pairs of plate members 34a made of ceramic, for example. , 34b and 36a, 36b. The plate thicknesses of these plate members 34a, 34b and 36a, 36b are omitted for simplification of the drawing. These plate members 34a, 34b and 36a, 36b define a flat contact surface between one segment 14 and another segment 14 adjacent to the segment in the extending direction b and the arranging direction a of the annular body 12 respectively. To do.

  The segment 14 is further attached to the outer peripheral surface 32b of the bag 26 and extends along each end face 28a, 28b of the bag 26, and one piece of two pieces constituting the line fastener 38, and each side surface 30a, 30b of the bag 26. And one piece 40a of two pieces constituting the hook-and-loop fastener 40.

  One piece of the wire fastener 38, which is an openable / closable fastener, includes a tape 38a, a plurality of elements (servo teeth) 38b attached to the tape, and a slider (open / close component) 38c attached to the element. The piece (not shown) is composed of a tape and a plurality of elements (service teeth) attached to the tape. For one segment 14 having a piece of line fastener 38, the other segment 14 adjacent to the one segment has the other of the two pieces of line fastener 38. One segment 14 and the other segment 14 adjacent thereto are connected to each other and released from each other by meshing and releasing the elements in both pieces of the wire fastener 38.

  In the illustrated example, the elements of both pieces of the line fastener 38 mesh at an upper position between one segment 14 and another segment 14 adjacent thereto. For this reason, during rainy weather, rainwater may drop between one and the other segments 14 through the two elements, thereby causing rain leakage on the temporary roof 10. In order to avoid this, for example, a cover (not shown) that covers one piece or the other piece of the wire fastener 38 is attached to the outer peripheral surface 32b of the bag 26. Alternatively, for example, the line fasteners 38 may be arranged such that the mutual meshing positions of the elements of the two pieces are on the outer peripheral surface 32b of the bag 26 of one segment 14 or the outer peripheral surface 32b of the bag 26 of the other segment 14. The two pieces of fasteners 38 are attached to the bag 26 of one segment 14 and the bag 26 of the other segment 14, respectively.

  Further, one piece 40a of the hook-and-loop fastener 40 includes a hook surface having a large number of hooks, and the other piece (not shown) includes a loop surface having a large number of loops. For one segment 14 having a piece 40 a of hook and loop fastener 40, the other segment 14 adjacent to the one segment has the other of the two pieces of hook and loop fastener 40. One segment 14 and the other segment 14 adjacent thereto are connected to each other and released from each other by pressing and peeling the hook surfaces and loop surfaces of both pieces of the hook-and-loop fastener 40.

  In addition, as a connection means between the segments 14, instead of the illustrated example in which both the line fastener 38 and the surface fastener 40 are used, only the line fastener 38 or only the surface fastener 40 can be used.

  On the ground, the temporary roof 10 connects a plurality of segments 14 to each other, thereby forming a plurality of rows of annular bodies 12, and then each through a mouth (not shown) provided in a bag 26 of each segment 14. The bag 26 can be assembled by supplying the fluid. The temporary roof 10 assembled on the ground can be lifted, for example, on the building frame using heavy equipment.

  One segment 14 that expands by the supply of fluid and the other segment 14 adjacent to the segment 14 have one end surface 28a of the bag 26 of one segment 14 and the bag 26 of the other segment 14 in the extending direction b of the annular body 12. And the other end face 28b of the first and second end faces 28b through the plate member 34a and the plate member 34b. At this time, both plate members 34a and 34b receive the expansion pressure of both bags 26 and are brought into close contact with each other.

  In addition, one segment 14 that expands by the supply of the fluid and the other segment 14 adjacent to the segment 14 have the side surface 30a of the bag 26 of one segment 14 and the bag of the other segment 14 in the arrangement direction a of the annular body 12. 26 abuts on the side surface 30b of the 26 through the plate member 36a and the plate member 36b. At this time, similarly, both plate members 36a and 36b receive the expansion pressure of both bags 26 and come into close contact with each other. The close contact between both plate members 34a and 34b and the close contact between both plate members 36a and 36b contribute to prevention of rain leakage through the segments 14.

  In the illustrated example, the plate members 34a and 34b and the plate members 36a and 36b cover all of the end surfaces 28a and 28b and the side surfaces 30a and 30b of the bag 26, respectively. Thus, a part of each end face 28a, 28b and a part of each side face 30a, 30b of the bag 26 can be covered.

  Further, when the one segment 14 and the other segment 14 adjacent thereto are brought into contact with each other, both the plate members 34a, 34b are aligned with each other and the both plate members 36a, 36b are aligned with each other. A plurality of concave portions and convex portions that can be engaged with each other can be provided on the plate member 34a and the plate members 36a and 36b. In the illustrated example, only one concave portion 42 is provided in one segment, and only a convex portion (not shown) is provided in the other segment 14 adjacent thereto. Instead of the illustrated example, both the concave portion and the convex portion can be provided in each of the one segment 14 and the other segment 14.

  Next, the two plate members 34a and 34b respectively attached to the both end faces 28a and 28b of the bag 26 can be folded (see FIG. 6). Here, each plate member 34a, 34b is bonded to a flat plate (not shown) made of ceramic, plastic, wood, metal or the like divided into three along the lines 11 and 12, and the surface of the flat plate. And a synthetic resin film (not shown). The illustrated lines 11 and 12 extend from the intersections between the end faces 28a and 28b and the side faces 30a and 30b of the bag 26 toward the intersection lines between the end faces 28a and 28b and the outer peripheral surface 32b, respectively. However, the lines 11 and 12 do not intersect. According to this, as shown in FIG. 6, after the plate members 34a and 34b of the segment 14 are folded along the lines 11 and 12, the other plate members are placed on the folded plate members 34a and 34b. 36a and 36b can be folded. According to this, storage and transportation of the segment 14 can be made easier. The foldable plate members 34a and 34b are made of, for example, a hard plastic flat plate (not shown) having folding grooves extending along the lines 11 and 12 instead of the illustrated example. can do. According to this, the flat plate can be bent along the lines l1 and l2.
