Abstract

PURPOSE: To transport an extension type structure by connecting respective sidewalls of a box-shaped part to a floor in such a state as freely raised/fallen and attaching connecting divided elements composed of a plurality of fan-shaped elements expanded like an accordion to the respective sidewalls. CONSTITUTION: When a jack 17 located in a sidewall side 5 is shortened, the sidewall 5 is gradually erected and at the same time the topmost fan element 141 of a fan element is moved on a rail 15 inward a box-shaped part 1 via rollers 16. The respective fan-shaped elements 141 , 142 , 143 , 144 , 14' are rotationally moved about a horizontal rotation axis X-X' in order so as to be folded in the box-shaped part 1. When the jack 17 located in the sidewall 5' side is shortened, the sidewall 5' is gradually erected and at the same time the fan-shaped element 14' is folded.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an expandable structure that can be transported by air, land or sea.

BACKGROUND OF THE INVENTION It is often necessary to be able to quickly construct relatively large buildings, such as conference rooms, wall panels, mobile banks or post offices, hospitals, battlefield clinics, and combat command centers.

For this reason, prefabricated buildings are currently being used.

[Problem to be solved by the invention] Prefabricated buildings currently available on the market are not necessarily easy to transport, and are time-consuming and troublesome, especially when assembled in unsafe areas. It is not possible to meet the various demands associated with the above.

In order to compensate for the above drawbacks, the French Patent Box 7925 has already been issued.
No. C111 proposes the use of a means of transport such as a semi-trailer trailer equipped with a moving room, but since this device is intended for road transport, it is not suitable for widespread use. Not yet.

An object of the present invention is to provide an expandable structure,
Its applications are virtually limitless, as it can be transported by aircraft or helicopter and is easily adapted to the equipment needed for the intended application (power generation, electrical systems, medical gases, fluid distribution, air conditioning, etc.). be.

Means for Solving the Problem This expandable structure has a central box-shaped structure having a floor, a riseable roof, fixed front walls with doors and/or windows, and side walls. portions are provided, each of said walls being articulated around a longitudinal axis fixed to the floor, and said side walls being approximately in a vertical or transport state so as to extend the floor and increase its surface area. The joint is configured to be able to move between a horizontally folded and unfolded state, and when the side wall is in the unfolded state, it cooperates with the roof and side walls to form a sealed sky that expands like an accordion. a divider is provided, and control means are provided for moving the roof of the central box-shaped portion from a high position to a low position or vice versa, and for moving the side walls from a transport condition to a deployed condition or vice versa. It is what it is.

Therefore, when the expandable structure is unfolded, its floor area is naturally the sum of the previous floor area and the 1m area of the side walls.

According to the invention, this expandable structure is characterized in that the control means cooperate with a hydraulic circuit to move the roof of the central box-shaped part from a low position to a high position and of the at least one side wall from a transport state. Consisting of double-acting remote-controlled hydraulic jacks capable of simultaneously and synchronously controlling the movement to the unfolded state or vice versa, the articulated segment is automatically folded or unfolded rearward again during said movement. It is characterized by:

As mentioned above, the expandable structure of the present invention has two locations;
That is, it automatically moves between the transport state (the roof is lowered and the side walls are in the transport state) and the deployed state (the roof is lowered and the side walls are in the deployed state), and the Any direction of movement may be used.

Naturally, the hydraulic circuit is composed of commonly used equipment (hydraulic unit, oil tank, electric distribution valve, reverse valve, etc.).

According to another feature of the invention, each articulating segment consists of generally cylindrical rigid sectors that telescopically fit into each other.

In order to synchronize the movements of the roof and facade as described above, it is necessary to attach the articulated parts in a special way, since the hydraulic jacks are operated in double action.

To this end, according to another feature of the invention, the articulating segments are each fixedly attached to the side wall and attached to a horizontal axis that can be rotated in a vertical plane and then slidable so that they can spread out like an accordion. A lowermost sector is provided which cooperates with a series of upper sectors.

In order to meet the above requirements without limiting the features of the invention, the expandable structure generally has a length of about 8 to 12 m, preferably about 9 m % height and Width of about 2-3 m%, preferably about 2.5 m%, in the expanded state, about 7-7.5 m.

It should be approximately 3 meters high. Therefore, the connected splitting body is
Preferably, a lowermost section is provided which cooperates with the four upper sections.

According to another feature of the invention, the liftable roof is simply supported by the upper part and the horizontal axis is automatically moved vertically to move the roof from a low position to a high position or vice versa. .

In order to maintain the sealability of the expandable structure, it is naturally necessary to secure two front panels to the roof so that they can slide along the front wall when the roof is moved.

According to another feature of the invention, in order to preserve the sealing properties of the entire expandable structure, each sector, in its deployed state,
8-15c+n with adjacent fan-shaped body.

Preferably they overlap by about 10 cm and each sector is preferably provided with side guide rollers and friction members to facilitate movement of the various sectors.

According to another feature of the invention, standard components, in particular through holes and/or angle pieces (1
, S, O, standard corners) to facilitate cargo handling and transportation.

Therefore, the base of the expandable structure according to the invention can be used for air cargo,
Transal, Hercules, Boein
It has the size and equipment to be able to be transported by g 747 cargo, etc.

According to another feature of the invention, each corner of the central box-shaped part is provided with a remotely controlled hydraulic column that can be raised and anchored. In use, this hydraulic strut cooperates with, for example, three mechanical struts, or finally anchors the expandable structure on the site. These various types of equipment can of course cooperate with auxiliary equipment (stairs, elevator platforms, etc.) that can fit inside the expandable structure.

According to another feature of the invention, the central box-shaped portion is constructed of a metal skeleton covered with a body of a double layer synthetic plastic material, such as polyester, surrounding a sandwich of high-density insulation.

Since the expandable structure acts as a side wall or floor when expanded, it is naturally necessary to reinforce the side wall with a steel frame or the like.

Of course, the expandable structure of the present invention may be adapted to fit other devices as required for a particular application.

[Action] The horizontal axis x-x' is moved by the expansion and contraction of the double-acting hydraulic jack 17.
is moved on a vertical plane to move the side wall 5.5° into the transport or unfolded state, expanding the floor space in the unfolded state and allowing air, land, and sea transport in the transport state.
