Description

Expansion type prefavricated house using dome member and its construction method

The present invention relates to a prefabricated house, and more particularly, it can be easily installed using a freestanding post and can be applied to the construction of a prefabricated house, crop cultivation facility, warehouse, and factory using a panel that does not form a column in the interior space. It relates to the foundation of an expandable prefabricated house using a dome member and its construction method.

The prefabricated house is one of the methods of constructing a building by the dry construction method, and various members used for construction are produced at the factory and then these members are only assembled at the construction site.

The dome or tunnel-shaped building is sometimes used as temporary accommodation used by the military or construction companies, as an exhibition facility in various exhibitions, and is also used as a cultivation facility for agriculture.

Although prefabricated houses are sometimes manufactured with the same members as sandwich panels, recently, panels of a certain size are manufactured using high-density expanded polystyrene (hereinafter referred to as high-density EPS), and then these EPS panels are combined to produce a building, and the exterior surface The building is also completed by finishing it with a dry-bit method.

In this case, the high-density EPS panel has sufficient self-rigidity, unlike the send position panel, so that when the thickness is 100 mm or more, the shape of the building can be maintained without a separate steel structure. Therefore, it is not only possible to complete a building just by continuously combining these high-density EPS panels, but also has the characteristic of being able to quickly and inexpensively build a building because it does not need to construct a separate frame.

Moreover, in the case of a dome-shaped or tunnel-shaped cross-section of a building completed using high-density EPS panels, structurally earthquake- and wind-resistance performance is also increased, which has the advantage of being safe from natural disasters such as typhoons and earthquakes. In addition, due to the characteristics of the high-density EPS panel, heat transfer is completely blocked, so it is very easy to artificially control the internal temperature and humidity.

As such, a building using high-density EPS panels that are structurally safe and do not need to separately install a steel structure used as a frame is easy to manufacture as a zero house with low energy consumption efficiency and low construction cost when used for residential purposes.

When used as an agricultural facility, various plants can be grown at low energy costs regardless of the season, thereby enhancing the cultivation competitiveness of farms.

In order to form the skeleton of such a structure, a pipe or wood having a predetermined diameter is cut to a required length, combined, and fixed by welding or nailing to form a structure.

This prefabricated facility was developed and used as a structurally stable dome or tunnel type facility.

In the conventional dome structure, a support frame, which is a semi-spherical or tunnel-shaped structure, is installed at regular intervals from the ceiling toward the base floor, and a plurality of divided structures are assembled between the support frames to form a wall, After installing the wire mesh on the inner and outer walls, cement mortar was poured for construction.

However, the conventional technique is almost the same as the construction method of a general house in which a support frame is installed, a wire mesh is installed, and then a cement mortar is poured. In addition, there was a problem in that the construction cost increases due to the use of various raw materials for construction.

To improve this, various dome houses were developed, but the foundation floor was replaced by pouring the foundation concrete at the bottom of the prefabricated facility. Therefore, it is not easy to assemble and combine the foundation concrete and the dome house, and there are problems in construction, as well as the problem that the structure of the concrete has a bad influence on the soil and the cost is high.

In addition, the dome house according to the prior art has a problem in that it is inconvenient to set the position of the foundation or the steel frame for installing the panel during construction.

In addition, the dome house according to the prior art has an inconvenient problem of reinstalling after a dismantling process in order to reselect a location when a steel frame is installed.

In addition, the dome house according to the prior art has a problem in that it is difficult to adjust the height because the length of the steel frame is fixed.

In addition, the dome house according to the prior art has a problem of low space utilization because there is a steel frame supporting the panel from the inside.

For this reason, it is easy to select and change the position of the steel frame when constructing the dome house, and there is an urgent need for an improved dome house and construction method that increases the utilization of internal space with a structure that does not require a steel frame for support in the house.
