Description

[Technical field]

[0001] The present invention relates to a curing member and a curing method for a building unit. [Background technology]

[0002] Conventionally, when a waterproof cover is applied around the top surface of a building unit during storage or transport of the building unit, plywood is laid on the ceiling and the waterproof cover is placed over it to make the entire unit lighter, so no plywood is used, and to prevent rainwater from accumulating on the waterproof cover, an air bag is provided in the waterproof cover and this air bag is inflated with compressed air to create a drainage gradient on the ceiling surface of the waterproof cover, as described in Japanese Patent Laid-Open Publication No. 61-257574; and, as described in Japanese Utility Model Publication No. 56-39085, elastic support pieces are stretched between opposing ceiling beams of the building unit in a bow-shaped, braced state, and a waterproof cover is placed over the elastic support pieces to create a drainage gradient on the ceiling surface of the waterproof cover.

[0003] However, lowering the plywood from the ceiling takes time and can involve dangerous work on top of the building unit (on the back of a truck). In addition, waterproof covers with air bags have the following disadvantages: the waterproof cover is complicated and heavy, a pneumatic device is required to inflate the air bag, and it takes a long time to inflate and deflate the air. Furthermore, in cases where elastic support pieces are used, the elastic support pieces must be deformed into a bow shape to engage with the ceiling beams and then the work of releasing this engagement must all be done on the top surface of the building unit, which is inconvenient.

[0004] Therefore, the applicant has developed a building unit curing device which, when covering the periphery of the upper surface of a building unit with a waterproof cover, places a cover lifting tool on the upper surface of the building unit and pulls a tensioning member of the cover lifting tool to change the cover lifting tool from a lying state to an upright state, thereby making it possible to lift the waterproof cover with the cover lifting tool in the upright state, the cover lifting tool being configured to include a lifting member having a deformation portion which can elastically deform into a bow shape relative to the upper surface of the building unit, a connecting member which connects one end portion of the deformed portion of the lifting member located on one side of the width direction of the building unit to the other side of the width direction around the building unit, and a tensioning member which pulls the other end portion of the deformed portion of the lifting member located on the other side of the width direction of the building unit to one side of the width direction of the building unit, thereby deforming the deformed portion of the lifting member into a bow shape and which connects to one side of the width direction around the building unit, We have proposed a curing device for a building unit in which the lifting member has a base board that is placed on the upper surface of the building unit and a deformed board that is connected to one end of the base board and folded over the base board, the deformed board constituting the deformed portion, the connecting member being connected to the other end of the base board, and the tension member being connected to the free end of the deformed board (Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 4187179 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the curing device for the building unit described in Patent Document 1 has a complicated structure, and the cover lifting tool changes from a lying state to a standing state by pulling the tension member, so a certain operation is required before the waterproof cover is applied. Also, because of the complicated structure, there is a risk of problems with durability. Furthermore, it is time-consuming to remove the curing and retrieve the curing device.

[0007] On the other hand, in recent years, in order to improve manufacturing efficiency, a line production method has been adopted even when manufacturing building units, where multiple people process and package (cover with waterproof covers) the building units that move along a conveyer belt. Even in this case, it is difficult for the building unit curing device to cover with a waterproof cover within the time it takes for the units to move along the line, and high work efficiency cannot be expected.

[0008] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a curing member for a building unit which has a simple structure, can be manufactured at low cost, is highly durable, and has excellent work efficiency even when manufactured using a line production method, and a curing method for a building unit which uses the same, and which allows the curing member to be recovered safely, quickly and easily, and a curing method for a building unit which uses the same. [Means for solving the problem]

[0009] The protective material for the building unit described in claim 1 comprises, when covering the upper surface of the building unit with a waterproof cover, a thin protective material that is arranged in parallel with the upper surface of the building unit and supports the waterproof cover, and a pillow member that is laid in a recess in the upper surface of the building unit and supports the protective material that is arranged on the upper surface, and the pillow member has a long retrieval string-like member at its longitudinal end, and also has a long retrieval string-like member at the end of the protective material.

[0010] The curing material for a building unit described in claim 2 is the curing material for a building unit described in claim 1, characterized in that the curing board has a folding portion along the width direction that allows it to be folded in two in the longitudinal direction.

[0011] The curing material for a building unit described in claim 3 is a curing material for a building unit described in claim 1 or 2, characterized in that the curing board has escape cutouts at the four corners to allow for the fixing members for hanging the building unit to escape.

[0012] The method of protecting a building unit as described in claim 4 is a method of protecting a building unit in which a waterproof sheet is covered using a protecting member for a building unit as described in any one of claims 1 to 3, and is characterized in that it includes the steps of: laying the pillow member on the upper surface of the building unit so that the recovery string member attached to the end of the pillow member hangs down to the outside of the building unit; unfolding the protecting board material folded in half and erecting a plurality of the protecting board materials in parallel on the upper surface of the building unit so that the recovery string member attached to the end of the protecting board material hangs down to the outside; and covering the upper surface of the protecting board material with a waterproof sheet. Effect of the Invention

[0013] The protective material for the building unit described in claim 1 comprises, when covering the upper surface of the building unit with a waterproof cover, a thin protective material which is arranged in parallel on the upper surface of the building unit and supports the waterproof cover, and a pillow member which is laid in a recess in the upper surface of the building unit and supports the protective material arranged on the upper surface, and the pillow member has a long retrieval string-like member at its longitudinal end and also has a long retrieval string-like member at the end of the protective material, so that it can support the protective material with enough strength to prevent it from bending even if the upper surface of the building unit has a recess and is not flat.

[0014] Furthermore, when laying the pillow members and erecting the protective boards, if the retrieval string-like member is hung on the outside of the side of the building unit, then when retrieving the protective members, they can be retrieved simply by pulling the retrieval string-like member from the outside, meaning that they can be retrieved without having to climb onto the building unit, thereby improving safety and work efficiency.

[0015] In addition, if the protective board 10 and the pillow member 20 are made of plastic cardboard or polystyrene foam and the short sides are covered with tarpaulin fabric or the outer surface is covered with a polyethylene sheet, the overall weight of the protective members (10, 20) can be reduced and durability can be improved. Also, they can be easily and inexpensively manufactured.

[0016] Furthermore, if the curing board is formed so that it can be folded in two, it becomes easy to store and transport, and it is also easy to carry and install, which contributes to improving work efficiency.

[0017] On the other hand, the building unit is provided with fixing members for hanging at its four corners so that it can be suspended and moved using a crane or truck crane, and a frame is provided around the upper surface of the building unit so that electrical equipment such as electric wires can be arranged thereon. Therefore, when the curing board is erected on the upper surface, escape notches are provided at the four corners of the curing board to allow the fixing members for suspending the building unit to escape, and when the curing board is erected on the building unit, the fixing members for suspension are not blocked by the curing board, making it easy to carry out the erection work.

[0018] Furthermore, when using the protective materials for the building unit to cover the building unit with a waterproof sheet, the process includes the steps of laying the pillow material on the top surface of the building unit so that the recovery string members attached to the ends of the pillow material hang down to the outside of the building unit, unfolding the protective board material folded in half and erecting multiple protective board materials in parallel on the top surface of the building unit so that the recovery string members attached to the ends of the protective board materials hang down to the outside, and covering the top surface of the protective board materials with a waterproof sheet.This makes it easy to install and also allows the protective materials to be safely and easily recovered.

[0020] An example of an embodiment of the present invention will be described in detail below with reference to the drawings. Figures 1 to 9 show a first embodiment of the present invention, in which the curing members (10, 20) of the building unit 30 according to the present invention include a curing board member 10 and a pillow member 20, which will be described later. 10 to 15 show a second embodiment of the present invention, which is a curing board member 10 used in a building unit 30 (see FIG. 10) in which the pillow members 20 are not required.

[0021] (First embodiment) Fig. 1 is a perspective view of a curing board according to a first embodiment of the present invention, where (a) is a perspective view of the two-foldable curing board in an unfolded state, (b) is a partially enlarged end view of the folding portion, and (c) is a perspective view of the board folded in two. Fig. 2(a) is a front view of the curing board, and (b) is a cross-sectional view of the same. Fig. 3(a) is a perspective view of a pillow member, and (b) is a cross-sectional view of the pillow member.

[0022] As shown in Figures 1 and 2, reference numeral 10 in the figures denotes a curing board material according to the present invention, which is a thin, plate-like member having an approximately rectangular overall shape, with the four corners cut away to form relief cutouts 15.

[0023] The curing board 10 is made of plastic corrugated cardboard (hereinafter referred to as "pladan"), with the ribs facing along the longitudinal direction and the cross section of the hollow portion aligned along the short side, and in order to form the bent portions (13, 14) in the longitudinal center and along the short side, a valley portion 13 is formed by heat pressing from the back side, the hollow portion of the cross section is heat welded, and the surface portion is left uncovered to form a hinge 14 so that it can be folded in two at the center. The bent portions (13, 14) form the board into two halves like the split body 11 and the split body 12, and the hollow cross section facing the short side is covered with a tarpaulin fabric and sewn to form the sewn portion 18, which is treated to provide strength that prevents rainwater from entering the hollow portion and prevents damage when placed on the ground.

[0024] A through hole 16 for fastening a string-like member for recovery, which will be described later, is formed near the short side of one of the half bodies 12. A long string-like member for recovery 17 is tied and fixed to the through hole 16 so that the curing board 10 can be recovered without climbing up to the building unit 30.

[0025] The size of the curing board 10 is about 1200mm in width W and 2500mm in length L, but it is not limited to these values, and the width W may be set to a size that a worker can hold, preferably about 900mm to 1300mm. The length L may be set to match the width of the building unit to which the curing board 10 is to be erected.

[0026] In addition, the protective board 10 is formed by forming the halves 11, 12 from plastic board and covering the hollow cross section facing the short side with tarpaulin fabric and sewing it to form the sewn portion 18, but it is not limited to this and can be formed from any material that is similarly light and easy to mold.

[0027] FIG. 3(a) is a perspective view of the pillow member, and (b) is a cross-sectional view of the pillow member.

[0028] In Fig. 3, 20 denotes a pillow member, which is laid in a recess in the upper surface of the building unit 30 to align the height of the upper surface of the building unit 30 with the height of the upper frame 31 of the building unit 30, and is formed by covering a long rectangular column-shaped polystyrene foam 21 with a polyethylene sheet 22 and sewing it, and has an eyebolt-shaped string attachment member 23 attached to one end surface for tying and fixing a long recovery string-like member 24. The length L2 of the pillow member 20 is set to be shorter than the width of the upper surface 32 of the building unit 30 described later.

[0029] A long recovery string member 24 is attached to the string body mounting member 23 so that the pillow member 20 can be recovered without climbing up the building unit 30. The length L2 of the recovery string member 24 is set to a length that allows the recovery string member 24 hanging down from the side to be pulled without climbing up the building unit 30.

[0030] In order to cover the building unit 30 with a waterproof cover 40 using the covering members 10, 20 of the building unit 30 having the above-mentioned configuration, a method of covering the building unit shown in FIG. 4 is suitable.

[0031] Figure 4 is a flowchart showing the process of covering a building unit with a waterproof sheet using the protective member of the present invention, Figure 5 is a schematic diagram showing the state of the building units flowing down the line, Figure 6 is a schematic diagram showing the state of laying pillow members on the building units flowing down the line, Figure 7 is a schematic diagram showing the state of installing protective plates on the pillow members of a building unit flowing down the line, Figure 8 is a schematic diagram showing the state of installing protective plates on the pillow members of a building unit flowing down the line with recovery string-shaped members hanging down the sides, and Figure 9 is a schematic diagram showing the state of covering the protective plates of a building unit flowing down the line with a waterproof sheet.

[0032] 5 to 9, 30 is a building unit that flows through the line manufacturing equipment, and as shown in Fig. 4, a frame 32 is arranged around the upper surface 31 of the building unit 30, and electrical components (not shown) such as electric wires are contained inside the frame 32. Scaffolding A is set up on both sides of the line of the line manufacturing equipment, and workers climb onto the scaffolding A to cover the line with a waterproof sheet 40 (covering work).

[0033] To cover the building unit 30 with the waterproof cover 40 using the covering members 10, 20 of the building unit 30, a worker first climbs up onto the scaffold A and lays the pillow members 20 at appropriate intervals on the upper surface 32 of the building unit 30, as shown in Fig. 4. At that time, the recovery string member 24 is laid so as to hang down to the outside of one side of the building unit 30 (ST1).

[0034] Next, the protective boards 10 are erected in the width direction on the pillow members 20 that have been laid at appropriate intervals so as to be parallel to the length direction of the building unit 30. At that time, the recovery string members 24 are laid so as to hang down to the outside of one side of the building unit 30 (ST2).

[0035] Then, the upper surface of the building unit 30 is made flat, and a waterproof sheet 40 is placed over the curing board 10 (ST3).

[0036] As described above, when the curing members (10, 20) of the building unit 30 are used to cure the building unit 30, even if the upper surface of the building unit 30 has a recess and is not flat, the pillow members 20 can support the curing board 10 with enough strength to prevent it from bending.

[0037] Furthermore, when laying the pillow members 20 and erecting the protective board material 10, if the retrieval string-like members 17, 24 are hung on the outside of the side of the building unit 30, then when retrieving the protective members 10, 20, they can be retrieved simply by pulling the retrieval string-like members 17, 24 from the outside, meaning that they can be retrieved without having to climb onto the building unit 30, thereby improving safety and work efficiency.

[0038] In addition, if the curing board 10 is molded from plastic cardboard or polystyrene foam and the sewing portion 18 covering the short side is made of tarpaulin fabric, it is possible to reduce weight and improve durability. In addition, it is easy to manufacture and can be manufactured at low cost.

[0039] Furthermore, if the curing board 10 is formed so as to be foldable in two, it becomes easy to store and transport, and is also easy to carry. Installation work is also easy, and work efficiency can be improved.

[0040] Furthermore, the building unit 30 is provided with fixing members (not shown) for hanging at its four corners so that it can be suspended and moved by a crane or truck crane, and a frame 31 is provided around the periphery of the upper surface 32, and is formed so that electrical equipment (not shown) such as electric wires can be arranged. Therefore, when erecting the curing board 10 on the upper surface 32, escape notches 15 are provided at the four corners of the curing board 10 to allow the fixing members (not shown) for hanging to escape, so that when erecting the curing board 10 on the building unit 30, the fixing members for hanging are not blocked by the curing board 10, and the erection work can be easily performed.

[0041] When the protective members 10, 20 of the building unit 30 are used to cover the building unit 30 with a waterproof sheet 40, the process includes a step (ST1) of laying the pillow member 20 on the upper surface 32 of the building unit 30 so that the retrieval string-like member 24 attached to the end of the pillow member 20 hangs down to the outside of the building unit 30, a step (S21) of unfolding the protective board material 10 folded in half and erecting multiple protective board materials 10 in parallel on the upper surface 32 of the building unit 30 so that the retrieval string-like member 17 attached to the end of the protective board material 10 hangs down to the outside, and a step (ST3) of covering the upper surface of the protective board material 10 with the waterproof sheet 40.This makes it easy to install and also allows the protective members to be safely and easily recovered.

[0042] (Second embodiment) Next, another embodiment of the present invention will be specifically described with reference to Fig. 10 to Fig. 14. Fig. 10 to Fig. 14 show a second embodiment of the present invention, in which the cover member used in another building unit 30A does not require the pillow member 20. Note that the same reference numerals are given to the members common to the first embodiment, and some of the descriptions will be omitted.

[0043] Figure 10 is a schematic diagram showing the state of other building units flowing through the line, Figure 11 is a flowchart showing the process of covering building units with a waterproof sheet using a protective member of the second embodiment of the present invention, Figure 12 is a schematic diagram showing the state of a protective plate being erected on the top surface of another building unit flowing through the line, Figure 13 is a schematic diagram showing the state of a protective plate being erected on the top surface of another building unit flowing through the line with a recovery string-shaped member hanging down the side, and Figure 14 is a schematic diagram showing the state of a waterproof sheet being covered over the protective plate of another building unit flowing through the line.

[0044] 10 and 12 to 14, 30A is a building unit that flows through the line manufacturing equipment, and as shown in the figures, a frame 32 is arranged around the upper surface 31 of the building unit 30A, and inside the frame 32, a vertical bar 33 of about the same height as the frame 32 is arranged in the length direction of the upper surface 32, and electrical components (not shown) such as electric wires are contained inside the frame 32. Also, scaffolding A is set up on both sides of the line of the line manufacturing equipment, and workers climb onto the scaffolding A to cover the line with a waterproof sheet 40 (covering work).

[0045] Therefore, in the case of the building unit 30A, since the vertical bars 32 are arranged on the upper surface 32, the pillow members 20 for erecting the curing board material 0, as in the curing members (10, 20) of the building unit in the first embodiment, are not required, and in the second embodiment, the same effect can be obtained with only the curing board material 10.

[0046] That is, as shown in Fig. 11, to cover the building unit 30A with the waterproof sheet 40 using the building unit curing member (10) in the second embodiment, the curing board 10 is first erected on the upper surface 32, i.e., on the frame 31 and the vertical beams 32, in the width direction so as to be parallel to the length direction of the building unit 30. At that time, the recovery string member 24 is laid so as to hang down to the outside of one side of the building unit 30 (ST1).

[0047] Then, the upper surface of the building unit 30 is made flat, and a waterproof sheet 40 is placed over the curing board 10 (ST2).

[0048] In other words, in the second embodiment, since the vertical bar 33 is present, the pillow member 20 is not necessary for erecting the protective board material 10, and in the second embodiment, step 1 (Figure 4) in the first embodiment can be omitted.

[0049] In this way, the reason why the installation of the pillow members 20 can be omitted is because the vertical bar 33 is provided inside the frame body 31 on which the top surface 32 is provided, and although one vertical bar 33 is provided in the vertical center of the top surface 32, several vertical bars may be arranged vertically. Also, the building unit may have a plurality of horizontal bars (not shown) arranged horizontally. In short, in the case of the second embodiment, it is sufficient that a height maintaining member is provided on top of the building unit so that the curing board material 10 can be unfolded and maintain a height approximately the same as that of the frame body 31.

[0050] Furthermore, although the protective board 10 is formed so as to be able to be folded in two, it may be formed so as to be able to be folded more than that, for example, into three or four folds.

[0051] Fig. 15 is a perspective view of another curing board according to the present invention, where (a) is a perspective view of the curing board that can be folded into three when unfolded, (b) is a partially enlarged end view of the folded part, and (c) is a perspective view of the board folded into three. Fig. 16(a) is a front view of the other curing board shown in Fig. 15, and (b) is a cross-sectional view of the same. Fig. 17 is a perspective view of another curing board according to the present invention, where (a) is a perspective view of the curing board that can be folded into four when unfolded, (b) is a partially enlarged end view of the folded part, and (c) is a perspective view of the board folded into four. Fig. 18(a) is a front view of the other curing board shown in Fig. 17, and (b) is a cross-sectional view of the same.

[0052] Another protective board material 10A according to the present invention shown in Figures 15 and 16, like the protective board material 10, is formed from a thin plate-like member having an approximately rectangular overall shape, and similarly has its four corners cut away to form relief cutout portions 15.

[0053] Furthermore, the curing board 10A is made of plastic corrugated cardboard (hereinafter referred to as "pladan"), with the ribs facing along the longitudinal direction and the cross section of the hollow portion aligned on the short side, and in order to form three folds (13, 14) along the short side at the positions where it is divided into three in the longitudinal direction, valleys 13 are formed alternately from the backside by heat pressing, the hollow portion of the cross section is heat welded, and the surface portion is left to form hinges 14, so that it can be folded in three in the longitudinal direction. The folds (13, 14) form a state in which it is divided into three 1 / 3 split bodies 10a, 10b, and 10c, and the hollow cross section facing the short side is covered with tarpaulin fabric and sewn to form the sewn portion 18, which is treated to provide strength that prevents rainwater from entering the hollow portion and prevents damage when placed on the ground.

[0054] A through hole 16 for fixing a retrieval string-like member described later is opened near the short side of the half 1 / 3 split body 10c at one end, and a long retrieval string-like member 17 is tied and fixed to the through hole 16 so that the protective board 10 can be retrieved without having to climb up to the building unit 30.

[0055] The size of the curing board 10A is about 1200mm in width W and 2500mm in length L, but is not limited to these values, and the width W may be set to a size that can be held by a worker, preferably about 900mm to 1300mm. The length L may be set to match the width of the building unit to which the curing board 10A is to be erected.

[0056] Since the curing board 10A has the above-mentioned configuration, it can be folded to 1 / 3 of its size, and can be carried even more compactly than the curing board 10.

[0057] Another protective board material 10B according to the present invention shown in Figures 17 and 18, like the protective board material 10, is formed from a thin plate-like member having an approximately rectangular overall shape, and similarly has its four corners cut away to form relief cutout portions 15.

[0058] Furthermore, the curing board 10B is made of plastic corrugated cardboard (hereinafter referred to as "pladan") like the curing board 10, and is oriented so that the ribs face along the longitudinal direction and the cross section of the hollow portion is located on the short side, and in order to form four folded portions (13, 14) in the short side direction at the positions where it is divided into four in the longitudinal direction, valley portions 13 are formed alternately from the back side by heat pressing treatment, the hollow portion of the cross section is heat-sealed, and the surface portion is left to form hinges 14 so that it can be folded into four in the longitudinal direction. Then, the folded portions (13, 14) are formed into four quarter-split bodies 10d, 10e, 10f, and 10g, and the hollow cross section facing the short side is covered with tarpaulin fabric and sewn to form sewn portion 18, which is treated to provide strength so that rainwater and the like does not enter the hollow portion and so that it is not damaged when placed on the ground.

[0059] A through hole 16 for fixing a retrieval string-like member described later is opened near the short side of the half 1 / 4 split body 10g at one end, and a long retrieval string-like member 17 is tied and fixed to the through hole 16 so that the protective board material 10B can be retrieved without having to climb up to the building unit 30.

[0060] The size of the curing board 10B is about 1200mm in width W and 2500mm in length L, but is not limited to these values, and the width W may be set to a size that can be held by a worker, preferably about 900mm to 1300mm. The length L may be set to match the width of the building unit to which the curing board 10 is to be erected.
