With the development of industry and economy, the movement of goods between countries has become more active, and the demand for standardized and easy-to-handle containers has increased. Therefore, with the efforts of the International Organization for Standardization Has been developed and is being applied to cargo transportation around the world.

The container is composed of a bottom plate, a side wall plate, a roof plate, a door and a column material though there is a slight difference depending on the purpose and function. The outer material and the structural material are mainly made of steel, Wood and non-ferrous metals.

These containers are used for people's temporary residential space or work space, taking into account the shape and size of the container, in addition to the original purpose of efficient cargo transportation and storage.

It is used as a temporary residential space or an office space through improvement work such as painting and exterior, introducing a window in the existing cargo transportation container, reinforcing the internal insulation, taking up less space, lowering the production cost compared with the existing building, Is relatively short and can be moved.

Also, the structural advantage of separating the exterior and the interior and securing an independent residential space is likely to continue to be used as a residential space or a work space.

Therefore, container structures which are not the standard container for freight transportation but borrowed only from the containers are manufactured and used for temporary residential use. The residential container must either achieve its purpose within a short period of time and move it (temporary site office, temporary worker accommodation, etc.), serve as temporary residential space (farmhouse, villa etc.) It can be used as a space (temporary shelter, temporary hospital, temporary command post, etc.) and in some cases it serves as a residential house.

However, there are many problems with existing containers, and improvement is required.

The main problem is that the existing containers are made of box-like structure and can be moved between places by using transportation equipment such as trucks, but they can not be adjusted or assembled in the field, There is a problem in utilization. In addition, the existing containers are generally made of steel, walls, roofs, floors and pillars are made so that changes in the outside temperature are transferred to the interior, and even if the interior is reinforced by heat insulation, the efficiency is inevitably lowered. In addition, since the weight of the container structure is largely increased, the heavy equipment must be used for transportation and installation, so that the consumer can not easily carry and install the container.

In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 is a view illustrating a structure of a lightweight sandwich panel for a prefabricated building according to an embodiment of the present invention.

1, a lightweight sandwich panel comprises a first composite sheet 1, a second composite sheet 2, a heat insulating functional sheet 3 and an adhesive 4, and the first composite sheet 1 ), An adhesive (4) layer, a heat insulating functional plate material (3), an adhesive (4) layer, and a second composite sheet (2) are sequentially laminated.

On the other hand, the present invention relates to a "first and second composite sheet (1, 2), in which a continuous-woven fabric or a nonwoven fabric thereof is used as a reinforcement material and a thermosetting resin or a thermoplastic resin is used as a matrix resin, (3) "obtained by foaming a thermosetting resin or a thermoplastic resin and a" light-weight sandwich panel "made of a thermosetting resin or a thermoplastic resin, and a" molded extrudate " And a method of assembling the multi-purpose prefabricated structure.

The composite sheet may be a "continuous composite fiber-reinforced composite sheet" proposed by the present applicant in a separate patent (Korean Registered Patent No. 10-1675009, No. 10-1328089, etc.).

Specifically, the " first and second composite sheet (1) " according to the present invention is a material obtained by compounding a reinforcing material and a matrix material, thereby remarkably improving mechanical properties. As the reinforcing material, a nonwoven fabric in which each fiber is fixed using a fabric made of a woven fabric such as plain weave, twill weave, or junior weave, such as glass fiber, carbon fiber, aramid fiber or naturally derived cellulosic fiber is used.

The " matrix material " is made of a thermosetting resin or a thermoplastic resin, and the base material is impregnated with the fibers of the reinforcement material to form a composite material, thereby exhibiting mechanical properties of the composite material.

As the thermosetting resin, an epoxy resin, an unsaturated polyester resin, a vinyl ester resin, a thermosetting urethane resin, a phenol resin, or the like can be used, but not limited thereto.

As the thermoplastic resin, a thermoplastic polyurethane resin, a polyamide resin, a polyester resin, a polyolefin resin, a polyketone resin, or the like may be used, but the present invention is not limited thereto.
