Description

  The present invention relates to a foldable assembly house (unit house) used as a temporary store, a field office, an office, or the like.

  Conventionally, assembly houses have been widely used as temporary offices for civil engineering sites, construction sites, and the like because construction work and removal work can be performed on site. Moreover, in order to improve the construction efficiency and the removal efficiency, as described in Patent Documents 1 to 3 and the like, assembly houses having various structures have been conventionally proposed.

  18-21 has shown the folding type assembly house 1 of the conventional structure described in patent document 1 among these. The assembly house 1 includes a ceiling member 2, a pair of ceiling support members 3 and 3 on the wife side, a plurality of girder side wall surface panels 4, and a floor member 5 in the assembled state shown in FIG. 18. ing. Of these, the ceiling member 2 has a substantially rectangular plate shape, and is configured by attaching a roof material, a ceiling material, and the like to a steel frame. Each of the ceiling support members 3 and 3 is configured by assembling a wall material, a window frame, or the like on a steel frame ceiling support frame, and each end portion (upper end portion in an assembled state) is It is connected with the longitudinal direction both ends of the ceiling member 2 so that rotation is possible via the hinges 6 and 6 (refer FIGS. 19-21), respectively. Each side wall surface panel 4 of the girder is composed of a wall material, a window frame or the like, and both sides of the girder side of the ceiling member 2, side sides of the ceiling support members 3 and 3, and girder of the floor member 5. It is attached in a rectangular frame composed of both sides. Further, the floor member 5 has a substantially rectangular plate shape, and is configured by attaching a floor plate or the like to a steel-made floor frame, and both longitudinal ends thereof are the other end portions of the ceiling support members 3 and 3. It is being fixed to (the lower end part in an assembly state).

  The assembled house 1 having the assembled state as shown in FIG. 18 is in the folded state as shown in FIG. 19, and the ceiling support members 3, 3 are placed between the ceiling member 2 and the floor member 5. Are arranged in a folded state in the horizontal direction, and the ceiling member 2, the ceiling support members 3, 3 and the floor member 5 are horizontally overlapped with each other. In this state, each girder side wall surface panel 4 is removed, and the other end portions (lower end portions in the assembled state) of the respective ceiling support members 3 and 3 are fixed to the floor member 5. Not.

  To assemble the assembly house 1 as shown in FIG. 18 from the folded state as shown in FIG. 19, the ceiling member 2 is lifted using the crane 7 as shown in FIG. 20. As a result, as shown in FIG. 21, both the ceiling support members 3 and 3 that have been folded in the horizontal direction are each turned 90 degrees to stand in the vertical direction. Next, the other end portions of the ceiling support members 3 and 3 are fixed to both end portions in the longitudinal direction of the floor member 5. Thereafter, each side wall surface panel 4 is attached to obtain the assembled house 1 in an assembled state.

  In the case of the foldable assembly house 1 having the conventional structure as described above, the ceiling support members 3 are utilized by utilizing the gravity by lifting the ceiling member 2 placed above the floor member 5 in the folded state. 3 can be turned upright. For this reason, when the assembly house 1 is assembled, the work of temporarily placing (moving) a part of the constituent members in another place becomes unnecessary, and the work efficiency can be improved. Further, there is an excellent point that it is possible to reduce the burden on the worker required to stand the ceiling support members 3 and 3 upright.

  However, in the case of the above-described conventional structure, in order to fix the other end portions of the ceiling support members 3 and 3 and both longitudinal end portions of the floor member 5, these members 3 and 5 are separate from each other. Connecting metal fittings (not shown) are used. When such a connecting bracket is used, the number of parts increases, which is disadvantageous in terms of construction efficiency. In view of such circumstances, the connecting bracket as described above is fixed or integrally provided in advance at one of the other end of the ceiling support member and the longitudinal end of the floor member. Is also possible. However, in this case, although the reduction in construction efficiency can be prevented, when the assembly house is folded, the connecting bracket interferes with other members, and the ceiling member, the pair of ceiling support members and the floor member There is a possibility that it will not be possible to overlap each other horizontally. For this reason, the loadability in the folded state of the assembly house is reduced (increase in the thickness dimension). Further, in the case of the assembly house 1 having a conventional structure, when the ceiling support members 3 and 3 are rotated, the other end edges of the ceiling support members 3 and 3 drag the upper surface of the floor member 5, There is also a possibility that the floor member 5 may be damaged such as a scratch. In the case of the conventional structure, the structure does not take into account the safety of the worker who works on the ceiling member 2, and there is room for further improvement in terms of ensuring safety. In the case of the conventional structure, since the space for storing the electrical wiring is not taken into consideration, the electrical wiring may be disconnected in the folded state. In addition, the electrical wiring is exposed to the indoor space, which may reduce the design of the indoor space. Further, in the case of the conventional structure, no special consideration is given to lifting or transporting by a crane while maintaining the folded posture. For this reason, when it is lifted by a crane, as shown in FIG. 20, only the ceiling member 2 and each of the ceiling support members 3 and 3 are lifted, and it is lifted while maintaining the folded posture. I can't. In the state shown in FIG. 19, when the stack is directly stacked on a truck bed or the like, the ceiling member 2 and the ceiling support members 3 and 3 and the floor member 5 are relatively displaced in the horizontal direction. May be out of balance.

The structure which can be accommodated in the container and the structure excellent in workability in the folded state are realized.

The foldable assembly house of the present invention includes a substantially rectangular ceiling member, a pair of ceiling support members, and a substantially rectangular floor member.
Among these, the ceiling member is composed of, for example, a steel-made ceiling frame, a roofing material (including a waterproof sheet, a heat insulating material, and the like) and a ceiling material (ceiling panel).
Each of the ceiling support members includes, for example, a steel frame support frame and a side wall surface panel, and one end portion (upper end portion in an assembled state) of each ceiling member is rotated to both longitudinal end portions of the ceiling member. It is rotatably connected via a pin, a hinge, or the like.
Further, the floor member is composed of, for example, a steel frame and a floor material (including a floor plate, a heat insulating material, etc.), and the other ends of the ceiling support members (in the assembled state) at both longitudinal ends thereof. The lower end is fixed.
In the folding assembly house of the present invention, the ceiling member is lifted from the folded state in which the ceiling member, each ceiling support member, and the floor member are horizontally overlapped with each other, and the both ceiling support members are erected. It can be assembled by rotating it to a state.

Particularly in the case of the folding assembly house of the present invention, the other end portion of the ceiling support member is provided with an overhanging connecting plate that projects upward in the folded state and is fixed to the floor member. .
Further, in the folded state, the overhanging connecting plate is housed in a housing portion opened on the lower surface of the ceiling member.

Moreover, when implementing the foldable assembly house of the present invention as described above, the floor members are separated from each other in the short direction of the floor member, for example, as in the invention described in claim 2. The floor member includes a floor frame having a pair of floor beams extending in the longitudinal direction, and a pair of telescopic beams connecting the ends of both floor beams in the longitudinal direction.
Then, by adjusting the length dimensions of these two telescopic beams, the distance between both ends in the length direction of the two floor beams can be adjusted (expanded / reduced).

When implementing the folding assembly house of the present invention, for example, as in the invention described in claim 3, the floor members are separated from each other in the short direction of the floor member. It comprises a floor frame having a pair of floor beams extending in the direction.
Further, when the ceiling support member is rotated, a roller provided at the other end of the ceiling support member rolls on the upper surface of the floor beam.

  When the invention described in claim 3 as described above is carried out, for example, as in the invention described in claim 4, the portion adjacent to the roller is engaged with the side surface of the floor beam. In addition, a guide rod portion is provided for preventing the roller from coming off from the upper surface of the floor beam.

Moreover, when implementing the folding type assembly house of this invention, the stance which comprises a fall prevention apparatus is provided in the upper surface of the said ceiling member like the invention described in Claim 5, for example.
The stanchion is supported by a rotating column supported to be rotatable from the horizontal direction to the vertical direction with respect to the ceiling member, and a slide supported to be slidable in the length direction of the rotating column with respect to the rotating column. An engagement piece and a receiving member fixed to the ceiling member are provided.
Further, the receiving member is provided with an engaging recess that engages with a slide engaging piece that moves downward when the rotating column is erected in the vertical direction and restricts the rotation of the rotating column. ing. Further, if necessary, the receiving member is provided with a guide portion that guides and moves the slide engagement piece upward when the rotating column is rotated from the horizontal direction to the vertical direction.
Furthermore, when carrying out the invention described in claim 5 as described above, for example, as in the invention described in claim 6, the ceiling member is formed by forming a retaining hole in the receiving member. A function for hooking a wire used when lifting the wire is provided.

  When the folding assembly house according to the present invention is implemented, the ceiling support member includes a ceiling support frame having a pair of pillars as in the invention described in claim 7, for example. . And at least one pillar part is comprised so that electrical wiring can be accommodated among these both pillar parts.

  Further, when the folding assembly house of the present invention is implemented, the ceiling support member and the floor member are arranged, for example, in the vertical direction in the folded state, for example, as in the invention described in claim 8. Secure with the fixing plate.

  Further, when implementing the folding assembly house of the present invention, for example, as in the invention described in claim 9, the floor member is provided on the forklift in a state of being separated in the longitudinal direction of the floor member. A pair of nail insertion portions for inserting the nails is provided.

According to the foldable assembly house of the present invention having the above-described configuration, it is possible to improve the construction efficiency while preventing the loadability from being lowered in the folded state.
In other words, in the case of the present invention, an extended connecting plate is provided at the other end of the ceiling support member, which extends upward in a folded state and is fixed to the longitudinal end of the floor member. For this reason, according to this invention, the improvement of the construction efficiency of an assembly house can be aimed at compared with the case where a connection metal fitting separate from a ceiling support member and a floor member is used. Further, in the folded state, the overhanging connection plate can be stored in a storage portion provided in an open state on the lower surface of the ceiling member, so that the overhanging connection plate can be prevented from interfering with other components. For this reason, even when this overhanging connecting plate is provided at the other end of the ceiling support member, the ceiling member, the ceiling support members, and the floor member can be horizontally overlapped with each other. Therefore, it is possible to prevent the loadability from being lowered in the folded state. As a result, according to the present invention, it is possible to improve the construction efficiency while preventing the loadability from being lowered in the folded state.

  Further, in the case of the invention described in claim 2, by adjusting the length dimension of the pair of telescopic beams constituting the floor frame, both ends in the length direction of the pair of floor beams constituting the floor frame are adjusted. The interval between the parts can be adjusted. For this reason, when adopting a structure that fixes a pair of overhanging connecting plates provided at the other end of each ceiling support member inside or outside the longitudinal ends of both floor beams, It is possible to achieve both improvement in workability of arranging (inserting) these both overhanging connecting plates between both ends in the lengthwise direction of the two floor beams and improvement in coupling strength at the fixed portion.

Further, in the case of the invention described in claim 3, when the ceiling support member is rotated, a roller provided at the other end of the ceiling support member causes the upper surface of the floor beam constituting the floor member to be , Rolling between the longitudinal intermediate portion and the longitudinal end portion. For this reason, it can prevent that the other end edge part of the said ceiling support member drags the upper surface of the said floor member, and is damaged. In the case of the invention described in claim 3, since the roller can roll on the upper surface of the floor beam until the ceiling support member stands vertically, the ceiling support member It is possible to effectively prevent the other end portion from being in the unsupported state before the ceiling work of the ceiling support member is completed (stands up). As a result, it is possible to prevent an impact load from being applied to the connecting portion between the ceiling member and the ceiling support member, and to improve the durability of the connecting portion.
Further, in the case of the invention described in claim 4, the guide rod portion provided adjacent to the roller engages with the side surface of the floor girder so that the roller is detached from the upper surface of the floor girder. You can prevent the ring. For this reason, it is possible to effectively prevent the ceiling member, the ceiling support members, and the floor member from rotating relative to each other around the vertical axis.

Further, in the case of the invention described in claim 5, it is possible to make the rotating column stand upright only by rotating the rotating column from the horizontal state to the vertical state. For this reason, the stanchion can be assembled without using a separate tool (fixed in an upright state).
Furthermore, in the case of the invention described in claim 6, since the stanchion can have a function for hooking the wire when the ceiling member is lifted, the number of parts and the cost can be reduced. .

  In the case of the invention described in claim 7, electrical wiring can be accommodated in the column portion of the ceiling support frame constituting the ceiling support member. For this reason, it is possible to effectively prevent the electric wiring from being disconnected in the folded state. Moreover, it can prevent that the design of the interior space of an assembly house falls.

  Further, in the case of the invention described in claim 8, the posture in the folded state can be maintained. For this reason, it is possible to improve workability such as lifting work and transport work in the folded state. Furthermore, in the case of the invention described in claim 9, since it becomes possible to move the assembly house using a forklift, the space for the moving work can be reduced and the work efficiency of the moving work can be improved. I can plan.
