Abstract

A temporary house (1) comprises a plurality of steel units (2) mounted to each other such that they together form a dome shaped house, wherein a cloth like material (5) is arranged on the outside of the steel units (2) and located at a distance from the steel units (2) so that an isolation material (6) may be arranged in the space between the steel units (2) and the cloth like material (5).

Description

TEMPORARY HOUSE

The present invention relates in general to a temporary house adapted to be used in case of nature disaster.

Background

Earthquakes, fires, tsunami, volcano, torrential rainj hurricane, debris flow, etc, all kinds of natural disasters that human beings cannot control today breaks out frequently worldwide, destroying family houses. Governments and aid

organizations often use tents and pre-fabricated houses to give roof to homeless people. However, such previously known solutions are often not enough as such simple shelters could sometimes cause problems with respect to water and sanitation. It also happens that these temporarily shelters are not safe enough when for example further earthquake activates again, people become scared by hurting again.

Examples of temporary houses which may be assembles on site are previously known, for example from GB 666,105 and JP 2007046452. There is however still a need for further improvement of such temporary houses.

Summary

The object of the present invention is a temporary house which may be easily transported and assembled in case of a natural disaster or the like.

The object is achieved by the temporary house in accordance with claim .

Embodiments are defined by the dependent claims. The steel temporary house in accordance with the invention will provide a rainproof shelter that is quick and simple to assemble. The house has a stable construction that is easy to move between different areas. The house could be insulated if the conditions need that. This emergency residence will provide a light weight, safe and durable construction, offering security and peace of mind to those affected by the disasters. Furthermore, it may be easily stacked and thus easily transported.

The construction of the house enables that isolating material does not have to be transported, and that natural elements such as soil, peat or plants may be used as isolating material.

Brief description of the drawings

Figure 1 illustrates a perspective view of an emergency house in accordance with the invention where the cloth like material has been omitted.

Figure 2 illustrates a perspective view of a temporary house showing the cloth like material being partly detached from the steel units. Figure 3 illustrates a magnification of a perspective view of the temporary house wherein a part of the cloth like material is partly detached from the steel units.

Detailed description

The invention will be described in detail below with reference to the accompanying drawings. The drawings shall not be considered drawn to scale since some features have been exaggerated in order to more clearly illustrate the invention. Moreover, the invention shall not be considered limited to the embodiments shown in the figures and described below, but may be varied within the scope of the claims. Figure 1 illustrates one embodiment of the temporary house 1 according to the invention. The house comprises a plurality of steel units 2, mounted to each other such that they together form a dome shaped house. The house 1 may stand on a plurality of feet 4 as shown in the figure. It is however also possible to arrange the house directly on the ground.

Each steel unit 2 comprises a rim 3 arranged at the edges of the unit 2 and extending essentially perpendicular to the surface of the unit. The rim 3 ensures that the cloth like material is arranged at a distance from the steel surface and thus provides as space there between, the space being adapted to be filled with an isolation material.

The isolation material ensures that the construction will provide sufficient warmth in case of cold weather conditions. The construction of the house enables that isolation material does not need to be transported to the site where the house should be assembled, but any type of suitable material present at the location can be used, such as soil, peat, or the like.

Figure 2 shows the house when the cloth like material 5 has been mounted to the steel units 2. One part of the cloth like material 5 is partly detached from the structure in order to show how it is mounted to the steel units 2.

Figure 3 shows a magnified view showing the cloth material 5 partly detached from a steel unit 2 and the rim 3. An insulating material is filled into the space between the steel unit and the cloth like material.

The steel units of the temporary house may be mounted to each other by any conventional means, such as a clamping devise or the like.

Moreover, the steel units may be easily manufactured of a thin plate or sheet, suitably of a thickness of 0.4-3 mm. Thereby, the weight of the construction is relatively low. In fact, it has been found that such a house may typically weigh less than 200 kilos. Furthermore, the steel units may easily be stacked. The house is thus easily transported.

A suitable steel to be used in the steel units comprises in percent by weight C max 0.25, Si max 0.7, Mn max 2.2 (preferably at least 1), Al max 0.05, Nb max 0.1 , Ti 0.05, B max 0.005, Cr max 0.8, V max 0.25, Cu max 0.3, Mo max 2.2, Ni max 2.0, balance iron and normally occurring impurities. Furthermore, the steel may suitably be provided with an external lacquer or the like in order to avoid corrosion.

Claims
