Thereby, even if it provides a side surface covering part, it does not get in the way of work.

  Hereinafter, an embodiment in which a building construction sheet of the present invention is embodied will be described with reference to the drawings.

[First Embodiment]
In the present embodiment, the building construction sheet is used as a rainy installation sheet for preventing the building unit from getting wet during the installation of the building unit.

  FIG. 1 is a perspective view showing the rainy weather installation sheet 1 in a state where the sheet member 31 is spread, and FIG. 2 is a plan view of FIG. As shown in FIG.1 and FIG.2, the rainy weather installation sheet | seat 1 as a building construction sheet | seat is provided with the box 11 as a to-be-suspended member suspended by a crane. The box 11 includes a frame member 12 that forms a quadrangle in a plan view, and a bottom member 13. One end of a sheet suspension member 14 such as a wire is attached to the corner portion of the upper end of the frame member 12. The seat suspension members 14 are formed to have substantially the same length, and the other end portions are collected in the suspension ring 15. Then, when the suspension ring 15 is hooked on the hook F on the crane side, the box 11 is suspended from the crane.

  One end of a unit suspension member 16 such as a wire is attached to the box 11. A unit suspension hook 17 is provided at the other end of each unit suspension member 16 that hangs down below the box 11.

  The box body 11 is provided with a plurality of air tubes 18 so as to extend from the four corners of the box body 11 to the side. More specifically, tube insertion holes 19 are provided at the lower portions of the four corners of the frame member 12 (see FIG. 6 described later). A straight air tube 18 is inserted through each tube insertion hole 19 one by one. These four air tubes 18 have the same shape and the same length, and are arranged so as to radiate around the box 11 in plan view. Each air tube 18 is attached to the bottom member 13 at the base end portion in such a state. For this attachment, an appropriate method such as hooking a hook attached to one side and a ring attached to the other side can be adopted. And the planar shape of the box 11 and each air tube so that the flat area of the virtual quadrangle formed when the tips of the air tubes 18 are virtually connected to each other is at least larger than the flat area of the building unit 2. The length of 18 is determined.

  As shown in FIG. 2, an air supply / discharge device 21 that supplies / discharges air to / from each air tube 18 is installed in the box 11. FIG. 3 is a configuration diagram of the air supply / discharge device 21. As shown in FIG. 3, the air supply / discharge device 21 includes a compressor 22, a switching valve 23, and a controller 24. The compressor 22 and the four air tubes 18 are connected via a switching valve 23. The compressor 22 and the switching valve 23 are connected to a controller 24, and the controller 24 is provided with a receiving device 26 that wirelessly receives a signal from the transmitting device 25. When the receiving device 26 receives the air supply signal output from the transmitting device 25, the controller 24 operates the switching valve 23 so that the outlet of the compressor 22 and each air tube 18 are connected. At the same time, the compressor 22 is driven. As a result, air is introduced from the compressor 22 into each air tube 18.

  On the other hand, when the receiving device 26 receives the exhaust signal output from the transmitting device 25, the controller 24 operates the switching valve 23 so that the air piping connected to each air tube 18 is opened to the atmosphere. At the same time, the drive of the compressor 22 is stopped. Thereby, the air in each air tube 18 is exhausted into the atmosphere. In the present embodiment, the controller 24, the transmission device 25, and the reception device 26 constitute a remote operation means.

  A sheet member 31 is attached to the box 11. The sheet member 31 is a waterproof sheet made of polyethylene or the like, and an attachment hole is formed in the center of the sheet member 31 according to the planar shape of the box body 11. The sheet member 31 is provided so as to cover the air tube 18 from above the air tube 18, and an opening edge portion 32 forming an attachment hole is attached to the outer peripheral surface of the frame member 12 of the box 11. Further, the air tube 18 existing inside the seat member 31 is attached.

  In the rainy weather installation sheet 1 having the above-described configuration, as shown in FIGS. 1 and 2, the four air tubes 18 extending radially from the box 11 are framed to open the sheet member 31, and the roof A portion 33 is formed. The roof 33 has substantially the same shape as a virtual quadrangle formed by virtually connecting the tips of the air tubes 18 in plan view. For this reason, the plane area of the roof part 33 is also larger than the plane area of the building unit 2. And the surplus part of the sheet | seat member 31 hangs down from the whole peripheral part of the roof part 33, and the side surface cover part 34 is formed of the surplus part. The side cover 34 has a length sufficient to cover the entire side surface of the building unit 2 that is suspended by the unit suspension member 16. A unit housing space 35 is formed by the roof portion 33 and the side surface covering portion 34.

  FIG. 4 schematically shows a state in which the building unit 2 is suspended using the rainy weather installation sheet 1. In the figure, the inner structure of the sheet member 31 is also indicated by a solid line. As shown in FIG. 4, when the building unit 2 is accommodated in the unit accommodating space 35 and the unit suspension hook 17 (not shown in FIG. 4) is hooked on the suspension ring 3 of the building unit 2, the building unit 2 is In the state accommodated in the accommodation space 35, it is suspended by the crane. Thereby, it is possible to prevent the building unit 2 from getting wet when the building unit 2 is installed even in rainy weather.

  Next, operations for expanding and closing the sheet member 31 will be described.

  FIG. 5 is a perspective view showing the rain installation sheet 1 with the sheet member 31 closed. As shown in FIG. 5, in a state where no air is introduced into each air tube 18, when the box body 11 is suspended, the sheet member 31 hangs down from the box body 11, that is, a closed state. In addition, the rainy weather installation sheet | seat 1 collects the sheet | seat member 31 on the box body 11 side from this state, makes it compact, and is made to carry in that state.

  FIG. 6 is an explanatory view showing a state where the air tube 18 rises. When the sheet member 31 is expanded, the operator operates the transmission device 25 to transmit an air supply signal in the above-described closed state. When the receiving device 26 receives this air supply signal, air is introduced into each air tube 18 by the operation of the controller 24 described above. Then, as shown in FIG. 6, each air tube 18 rises gradually from the initial state 18 a, rises through an intermediate state 18 b, and enters an upright state 18 c when the air is filled. Thus, as the air tube 18 rises, the sheet member 31 begins to gradually expand. If all the four air tubes 18 are in the standing state 18c, the sheet member 31 is completely expanded (see FIGS. 1 and 4). The unit accommodating space 35 is formed.

  On the other hand, when the installation work of the building unit 2 is completed and the sheet member 31 is closed, the operator operates the transmission device 25 to transmit an exhaust signal. When the receiving device 26 receives this exhaust signal, the air in each air tube 18 is exhausted into the atmosphere by the operation of the controller 24 described above. Then, contrary to the previous case, each air tube 18 tries to return from the standing state 18c to the initial state 18a through the midway state 18b. Thus, as each air tube 18 is deflated, the sheet member 31 is also gradually closed.

  The rainy weather installation sheet 1 of the present embodiment described in detail above has the following excellent effects.

  In this rainy weather installation sheet 1, each air tube 18 in a state of being filled with air expands the sheet member 31, and when the air in the air tube 18 is exhausted, the air tube 18 is deflated and the sheet member 31 is closed. It has become. That is, the air tube 18 serves as a framework for opening and closing the seat member 31. For this reason, the structure is simpler and lighter than the conventional opening / closing structure of an umbrella device. Thereby, handling becomes easy at the time of carrying around the rainy weather installation sheet | seat 1, the opening / closing operation | work of the sheet | seat member 31, etc. FIG. Moreover, since the weight is reduced, the suspension load limit of the building unit 2 can be increased as compared with the case of using a conventional umbrella device.

  In addition, because it is light and easy to handle, it is possible to install the building unit 2 using the rainy installation seat 1 even when the weather is unstable but it is not raining at the start of work. The building unit 2 can be prevented from getting wet by immediately responding to rain. When it is not raining, the building unit 2 may be suspended in the unit accommodating space 35 as in rainy weather, and after closing the sheet member 31, it is further lifted and held on the box 11 side. In this state, the building unit 2 may be suspended.

  This rainy weather installation sheet 1 has not only the roof 33 but also a side cover 34 that covers the entire side of the building unit 2 in a suspended state. Thereby, unlike the structure which has only the part equivalent to the roof part 33, the unit 2 can be further prevented from getting wet during the installation work of the building unit 2.

  In addition, since an air tube becomes a framework and the weight became light, there may also be a concern that the rainy weather installation sheet 1 is easily affected by wind during installation work. However, an air supply / discharge device 21 is installed in the box 11 in the rainy weather installation sheet 1. The influence of wind is sufficiently suppressed by the weight, and if it is still greatly affected, it can be said that the weather is not suitable for the installation work of the building unit 2 in the first place. For this reason, it can be said that there is almost no problem with the above-mentioned concerns.

  In addition, this Embodiment is not limited to said content, For example, you may implement as follows.

  The number of air tubes 18 is not limited to four, and may be appropriately different depending on the shape of the roof portion 33. For example, if three air tubes 18 are provided radially, a roof portion 33 having a triangular plan shape is formed, and if five air tubes 18 are provided radially, a roof portion 33 having a pentagonal plan shape is formed. Is done. Moreover, in this Embodiment, if the air tubes 18 are further increased from four and arrange | positioned radially, the roof part 33 can be reinforced by the increase in a framework.

  As shown in FIG. 7A, in addition to the radially provided air tubes 18, an air tube 40 formed in an annular shape along the periphery of the roof portion 33 is provided, and the insides of both the air tubes 18 and 40 are connected. It is good. In this configuration, if the radial air tube 18 and the annular air tube 40 are filled with air, they become a framework and the sheet member 31 can be expanded. In addition, it is good also as a structure which provided only the cyclic | annular air tube 40 instead of the radial air tube 18. FIG.

  As shown in FIG. 7 (b), a plurality of tube bodies 41, 42 having different lengths are integrally combined to form the air tube 18, and air is supplied to and discharged from each tube body 41, 42 independently. You may be able to do it. According to this configuration, the plane area of the roof portion 33 can be changed as necessary by appropriately selecting the tube bodies 41 and 42 into which air is introduced, for example, to match the size of the building unit 2 to be suspended. For example, if air is introduced into the first tube body 41, the first roof portion 43 is formed, and if air is introduced into the second tube body 42 shorter than the first tube body 41, the first roof portion 43 has a flat area. A small second roof portion 44 is formed.

  Certainly, it is not impossible to change the plane area of the roof portions 43 and 44 even in a conventional structure using an arm member and a link mechanism. However, there is a problem in that the originally complicated structure is further complicated. On the other hand, in the configuration in which the tube bodies 41 and 42 are used as a framework as in this example, the structure is simple because only the number of the tube bodies 41 and 42 is increased.

  As shown in FIG. 7C, an air tube 45 partitioned into a plurality of tube bodies 45a and 45b may be provided so that air can be supplied and discharged independently from each tube body 45a and 45b. . Also by this structure, the plane area of the roof parts 43 and 44 can be changed as needed by selecting appropriately the tube bodies 45a and 45b which introduce | transduce air.

  Each air tube 18 may be configured to bend downward at the periphery of the roof portion 33 in a state where the air is filled, and the bent portion may be a framework of the side cover portion 34. According to this configuration, since the side surface covering portion 34 is maintained in a predetermined shape by the framework, it becomes easy to cover the building unit 2 with the rain installation sheet 1 when the building unit 2 is unloaded.

  The side surface covering portion 34 is not essential, and only the roof portion 33 may be formed when the sheet member 31 is expanded. This configuration is the same as the configuration in which the side cover portion 34 is provided in that the air tube 18 serves as a framework for opening and closing the seat member 31. Therefore, effects such as easy handling and an increase in the suspension load limit of the building unit 2 can be obtained in the same manner.

  The air supply / discharge device 21 may be provided outside the rainy weather installation sheet 1, for example, on the crane side. According to this structure, the weight of the rainy weather installation sheet | seat 1 becomes still lighter, and handling, such as carrying around, becomes still easier. In this case, the rainy weather installation sheet 1 is certainly susceptible to the influence of the wind, but if the wind is calm, there will be no problem with this point.

  The air supply / discharge device 21 may be configured to be detachable from the box 11. According to this configuration, the air supply / discharge device 21 is normally removed from the box body 11 so as to be easily handled, and the air supply / discharge device 21 is appropriately installed in the box body 11 in consideration of the situation at the site. It is also possible to handle. As a result, it can be used flexibly according to the situation at the site.

  In order to prevent rainwater from accumulating in the box 11, the box 11 may be provided with a lid member, or a drainage device may be provided instead of the lid member.

  As a configuration for discharging the air in the air tube 18, an exhaust device such as a vacuum pump may be provided instead of mere air release. Further, the connection may be switched from the discharge side to the suction side of the compressor 22 so that both the air introduction and suction are performed by the compressor 22. According to this configuration, complete air venting that is difficult only by opening to the atmosphere can be easily performed. Therefore, it is easy to perform the operation of closing the sheet member 31 and storing the rain installation sheet 1 in a compact manner.

[Second Embodiment]
In the present embodiment, the building construction sheet is used as a temporary roof of a building in which a building unit is installed, specifically, a temporary roof of a building that has been installed on the first floor (hereinafter referred to as a first floor building). Yes. In addition, since this temporary roof has the same structure as the rainy weather installation sheet 1 demonstrated in 1st Embodiment, it attaches | subjects the same code | symbol about it, and abbreviate | omits description suitably, and demonstrates below centering on a different part. To do.

  FIG. 8 is a perspective view showing a temporary roof. As shown in FIG. 8, the temporary roof 4 is not provided with the unit suspension member 16 and the unit suspension hook 17. Further, the sheet member 31 is formed so that the length of the sheet member 31 hanging from the box 11 is longer than that of the rain installation sheet 1 so as to sufficiently cover the upper surface of the first floor building 5. And the box 11 is arrange | positioned above the 1st floor building 5, and air is introduce | transduced into each air tube 18 similarly to the rainy weather installation sheet | seat 1, and the sheet | seat member 31 is spread as it becomes a framework. Thereby, the main roof portion 55 is formed on the temporary roof 4 as a portion corresponding to the roof portion 33 of the rainy weather installation sheet 1.

  Next, when installing the temporary roof 4, as shown in detail in FIG. 9, a temporary pillar 51 is provided at the upper corner of the first-floor building 5. Since the first-floor building 5 of this embodiment has a quadrangular plan shape, four temporary columns 51 are provided, one for each protruding corner. In addition, since the planar shape of the first-floor building 5 is not limited to a quadrangular shape, in that case, a plurality of temporary pillars 51 are provided at appropriate corners and corners so as to sufficiently cover the upper portion of the first-floor building 5. Provided.

  The temporary column 51 has a base 52 attached to the upper end of the first-floor building 5. The base portion 52 is provided with a column portion 53 that rises in the vertical direction from the upper surface thereof, and a horizontal protrusion 54 that extends in the horizontal direction. The virtual planar shape formed by virtually connecting the tips of the horizontal protrusions 54 of the temporary columns 51 is slightly larger than the planar shape of the first-floor building 5.

  In the state where the main roof portion 55 is formed, the surplus portion of the sheet member 31 that hangs down from the entire peripheral portion of the main roof portion 55 is attached to the tip end portion of the column portion 53 of each temporary column 51 inside thereof. As a result, the first extended roof portion 56 is formed around the main roof portion 55.

  Further, the surplus portion of the sheet member 31 that hangs down from the entire peripheral edge of the first extended roof portion 56 is attached to the tip of the horizontal protrusion 54 of each temporary column 51 inside thereof. As a result, the second extended roof portion 57 is formed around the first extended roof portion 56. The planar shape of the entire roof portion including the second extended roof portion 57 is substantially the same shape as the virtual planar shape formed by virtually connecting the tip portions of the horizontal protrusions 54. As described above, since the virtual planar shape is slightly larger than the planar shape of the first floor building 5, the upper portion of the first floor building 5 is sufficiently covered by the main roof portion 55 and the two extended roof portions 56 and 57. Yes. And the surplus part hangs down also from the peripheral part of the 2nd extended roof part 57, and the side surface covering part 58 is formed of the surplus part. The upper part of the side surface of the first-floor building 5 is covered with the side surface covering portion 58.

  In addition, regarding the configuration for attaching the sheet member 31 to the column portion 53 and the horizontal protrusion 54, the hook as the attached portion attached to the sheet member 31 is hooked in the attachment hole provided in the column portion 53 and the horizontal protrusion 54. (Not shown). However, other appropriate methods such as providing a ring instead of the mounting hole, or providing the ring and the hook in reverse can be adopted.

  By installing the temporary roof 4 having the above configuration on the first-floor building 5, various constructions necessary for the ceiling portion of the first-floor building 5, such as wiring work and unit connection work, can be performed even in rainy weather. .

  Next, installation work and removal work of the temporary roof 4 will be described.

  Also in the present embodiment, as in the rainy weather installation sheet 1, the sheet member 31 is in a closed state when no air is introduced into each air tube 18. When air is introduced into the air tubes 18 above the first-floor building 5, the air tubes 18 expand and the sheet members 31 are expanded, thereby forming the main roof portion 55. Then, if the excess part of the sheet | seat member 31 is attached to the pillar part 53 and the horizontal protrusion 54 of each temporary pillar 51 one by one, the 1st and 2nd extended roof parts 56 and 57 and the side cover part 58 will be formed. Thereby, the temporary roof 4 is installed.

  On the other hand, when removing the temporary roof 4, after removing the sheet member 31 from each temporary column 51, the air in each air tube 18 is exhausted. Then, each air tube 18 is deflated and the sheet member 31 is gradually closed. If it is removed from above the first-floor building 5, the removal work of the temporary roof 4 is completed.

  The temporary roof 4 of the present embodiment described in detail above has the following excellent effects.

  In the temporary roof 4, the air tube 18 plays a role of the framework of the main roof portion 55. For this reason, the structure is simple and the weight is light as compared with a framework including a plurality of arm members and a link mechanism for connecting them. Thereby, it becomes easy to carry and handle the work for forming the main roof portion 55.

  After the main roof portion 55 is formed, the extended roof portions 56 and 57 are formed by attaching the surplus portion of the sheet member 31 to the temporary pillar 51 provided in the first floor building 5. For this reason, the temporary roof 4 is fixed to the first floor building 5. In this regard, in the configuration in which the temporary roof 4 is fixed to a scaffold installed around the first-floor building 5, the wind pressure received by the temporary roof 4 is input to the scaffold. For this reason, it is necessary to reinforce the scaffolding, which leads to an increase in labor and construction costs. On the other hand, according to the structure which fixes the temporary roof 4 to a building via the temporary pillar 51 like this Embodiment, special structural reinforcements, such as reinforcement of a scaffold, are unnecessary. In particular, in the case of a unit-type building, the building in which the installation of each floor portion is completed has a strength that can sufficiently withstand the wind pressure received by the temporary roof 4. For this reason, even if the temporary roof 4 is fixed to the unit type building, it is not necessary to apply special reinforcement to the building. Thereby, an increase in labor and construction cost can be suppressed.

  The temporary roof 4 has a side surface covering portion 58 that covers the upper part of the side surface of the first floor building 5. For this reason, compared with the structure which has only the main roof part 55 and the extended roof parts 56 and 57, it can prevent that rain enters into the ceiling part of the first-floor building 5. FIG.

  The temporary column 51 has a horizontal protrusion 54, and the sheet member 34 is attached to the tip of the horizontal protrusion 54. The virtual planar shape formed by virtually connecting the front ends of the horizontal protrusions 54 is slightly larger than the planar shape of the first floor building 5. For this reason, the side surface covering portion 58 is held away from the outer wall of the first-floor building 5, and a work space can be secured for performing various constructions on the upper portion of the outer wall of the first-floor building 5. Thereby, even if the side surface covering portion 58 is provided, it does not interfere with the work.

  The temporary roof 4 is not used only for the first-floor building 5, but may be used for a building where the installation of each floor is completed. Moreover, it may not be used only for the unit type building but may be used for a building built by a conventional construction method.

  Further, the side surface covering portion 58 is not essential, and the main roof portion 55 and the extended roof portions 56 and 57 may be simply formed. Even in this configuration, effects such as easy handling and the need for special reinforcement can be obtained in the same manner.
