[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a curing device for a building unit.
[0002]
[Prior art]
Conventionally, when a waterproof cover is covered around the upper surface of a building unit when the building unit is stored or transported, the plywood is not used to reduce the overall weight of the cover that is covered with the plywood and covered with the waterproof cover. In order to prevent rainwater from accumulating on the ceiling, an air bag is provided on the waterproof cover as described in JP-A-61-257574. As described in Japanese Utility Model Publication No. 56-39085, the elastic support piece is bridged between the opposing ceiling beams of the building unit in the form of a bow and deformed, and above the elastic support piece. There are some which provide a drainage gradient on the ceiling surface of the waterproof cover by covering it with a waterproof cover.

FIG. 1 shows a waterproof structure around the upper surface of the building unit 1 when the building unit 1 (frame structure of the pillar 2, the floor beam 3, and the ceiling beam 4) is stored in a storage area or transported on a truck bed. This is an example in which the curing device 10 is used when covering the cover 101. In FIG. 1, a mini waterproof cover 102 is interposed inside a waterproof cover 101 that covers the entire building unit 1.
[0020]
The curing device 10 places the cover lifting tool 11 at a single position or a plurality of positions (two positions in FIG. 1) in the longitudinal direction of the upper surface of the building unit 1 (ceiling joists 5 and the scaffolding board thereon). By pulling a tension belt 24 (described later) of the cover lifting tool 11 from the ground, the deformation board 22 of the lifting member 20 (described later) of the cover lifting tool 11 is changed from a flat state to a U-shape. The waterproof cover 101 can be lifted by the deformed board 22 in the upright state. Thereby, a drainage gradient is applied to the ceiling surface of the waterproof cover 101 so that rainwater does not collect on the waterproof cover 101.
[0021]
The cover lifting tool 11 includes a lifting member 20 (substrate board 21 and deformation board 22), a connection belt 23 (connection member), and a tension belt 24 (tensile member).
[0022]
The lifting member 20 includes a board 21 that is placed on the upper surface of the building unit 1, and a deformation board 22 that is connected to one end 21 </ b> A of the board 21 and is folded over the board 21. The deformation board 22 constitutes a deformation portion 20A that is elastically bowed from the flat state to the upper surface of the building unit 1 and changes to the above-described U-shaped standing state.
[0023]
The connecting belt 23 is attached and connected to the other end 21 </ b> B of the substrate board 21. As a result, the connecting belt 23 is positioned on the other side in the width direction around the building unit 1 by passing the one end portion 22A located on one side of the deformation board 22 in the width direction of the building unit 1 through the board board 21. Is connected to the ceiling beam 4B (or the floor beam 3B located on the other side) by using a mounting portion 23A such as a bolt (FIG. 4).
[0024]
The tension belt 24 is connected to the free end 22B (the other end) of the deformation board 22. As a result, the tension belt 24 pulls the other end 22B of the deformation board 22 to one side in the width direction of the building unit 1 to elastically deform the deformation board 22 into a bow, and the width in the circumferential direction of the building unit 1 It is connected to the floor beam 3A located on one side of the direction in a tensioned state using an attaching portion 24A such as a hook (FIG. 4).
[0025]
As shown in FIG. 3, the substrate board 21 is made of a thin plastic board (for example, 2 mm thick polyethylene board) 31 covered with a bag-shaped plastic sheet (for example, polyethylene sheet) 32. At this time, the substrate board 21 is fixed by bonding both side edges of the narrow plastic sheet 33 to the center in the width direction of the outer surface extending from the center in the longitudinal direction to the one end side of the plastic sheet 32, etc. A tunnel-shaped insertion portion 34 through which the above-described tension belt 24 connected to the other end portion 22B of the 22 is passed is formed.
[0026]
Further, as shown in FIG. 2, the deformable board 22 is formed by covering a thin plastic board (for example, 3 mm thick polyethylene board) 41 with a bag-shaped plastic sheet (for example, polyethylene sheet) 42. At this time, the deformable board 22 is fixed to both side edges of the narrow plastic sheet 43 by bonding or the like at the center in the width direction of the surface of the plastic board 41 over the entire length in the longitudinal direction. The elastic body 45 is integrated with the plastic board 41 by loading the band 44 with a band-shaped elastic body 45 such as FRP glass fiber.
[0027]
Hereinafter, the use procedure of the curing apparatus 10 will be described.
(1) The lifting member 20 (the board board 21 and the deformation board 22) of the cover lifting tool 11 is placed on the upper surface of the building unit 1. The longitudinal direction of the lifting member 20 is matched with the short direction of the building unit 1, and an appropriate number of lifting members 20 are placed in the longitudinal direction of the building unit 1.
[0028]
(2) The attachment portion 23A of the connection belt 23 connected to the other end portion 21B of the substrate board 21 of the lifting member 20 is connected to the ceiling beam 4B on the other side of the building unit 1 (FIG. 5A).
[0029]
(3) The tension belt 24 connected to the other end 22B of the deformation board 22 of the lifting member 20 is hung on one side surface of the building unit 1, and the tension belt 24 is pulled to operate the deformation board 22. While being deformed like a bow from the flat state to the upright state, the attaching portion 24A of the tension belt 24 is connected to the floor beam 3A on one side of the building unit 1 in a tensioned state (FIG. 5B).
[0030]
(4) Covers 102 and 101 are placed on the lifting member 20 in order to cover the building unit 1.
[0031]
Note that the bow-shaped deformation height of the deformation board 22 formed by the pulling operation of the pulling belt 24 is adjusted by adjusting the length of the pulling belt 24 by the length adjusting unit 25, and the small height shown in FIG. , (B).
[0032]
Moreover, it is preferable to set the bow-shaped deformation top of the deformable board 22 at a substantially central portion in the short direction of the building unit 1, and when the short dimension of the building unit 1 is about 2500 mm, for example, the board board 21 and the deformable board 22. Is 1550 mm, and the length of the insertion portion 34 for the tension belt 24 provided on the board 21 is 700 mm. The short dimension of the board board 21 and the deformation board 22 is, for example, 470 mm, and an appropriate number of cover lifting tools 11 are used depending on the long dimension of the building unit 1.

Further, the lifting width by the deformation board 22 is widened, and the waterproof cover 101 can be stably lifted by using a small number of the cover lifting tools 11.
[0037]
(5) Since the substrate board 21 and the deformation board 22 of the lifting member 20 are composed of the thin plastic boards 31, 41, the lifting member 20 can be made light and compact, and take-out property and storage property after removal are good.
[0038]
(6) Since the belt-like elastic body 45 is attached to the deformable board 22, the elastic strength of the deformable board 22 and the strength of the waist can be increased, and the bow deformability can be easily improved.
[0039]
(7) Since the insertion portion 34 of the tension belt 24 is provided on the substrate board 21, the tension operability of the tension belt 24 can be improved.
[0040]
