Description

Modular Archit1ect1ure Using the Composite Insulation Panel with Fire Partition}

The present invention relates to a prefabricated building using a composite insulation panel, and the composite insulation panel is arranged so that the outer wall of the prefabricated building has a fire protection section, and the insulation and fire prevention performance between unit units of the prefabricated building is improved by using an airtight fire tube and a fire protection barrier. It relates to a prefabricated building that can be improved.

In recent years, as the age of low birthrate and aging population has entered, the demand for residential model development is increasing significantly.

In particular, the demand for dormitory and housing improvement for young people and college students is also increasing. Accordingly, modular buildings that are recognized as prefabricated buildings that can be quickly supplied by shortening the construction period by 1/2 are attracting attention, and related research is actively being conducted. It's going on.

Unlike existing buildings that carry out most of the processes in the field, modular buildings are manufactured and installed in the factory in advance with various interior materials, mechanical equipment, and electrical wiring in a module structure composed of cubes such as a number of Lego blocks in a factory, such as a car. It refers to a building that is completed by transporting it to the site.

In other words, as a high-efficiency building incorporating the advantages of the manufacturing industry in a factory, it has the advantage that it is possible to manufacture a module factory for the structure, interior and exterior, and facilities, and easy renovation.

In addition, by assembling a unit unit, it is easy to expand and renovate and provide a quick supply. In particular, as a building that responds to the demands of customers, it can be supplied in various models according to the style of the customer.

In order for standardized parts and materials manufactured in the factory as described above to be immediately constructed without field processing, gaps for each part and material inevitably occur.

In other words, even for standardized materials, construction errors occur depending on the site conditions and construction technology during construction at the site, and extra dimensions for bonding are required when joining with adjacent materials.

Therefore, if the manufacturing dimensions and the module nominal dimensions are set to be the same, the standards for securing mutual areas are violated due to such errors or construction margins, causing cutting in the field. Therefore, there is a need for a free space to handle errors or construction margins that occur during production and construction, and this is called a gap.

This gap value is composed of the sum of the construction error and the construction margin, and if the construction error does not occur, the maximum gap value occurs.

Therefore, in standardized construction, how to deal with this gap is a very important issue.

In particular, there is a problem in that thermal insulation performance between unit units is deteriorated due to such gaps formed between unit units during field construction.

In addition, a certain gap between units formed when unit units are combined is expected to be a fire movement path in the event of a fire, and thus it is required to block the movement path thereof.

On the other hand, the insulation method of a building includes an internal insulation system installed inside the building and an external insulation system installed outside the building.

The internal insulation system installed inside the building is easier to install than the external insulation system, but has a disadvantage in that the insulation effect is inferior to the external insulation method that covers the entire exterior of the building.

In recent years, the thermal insulation performance has been gradually strengthened in terms of energy saving, and most of the buildings are inclined to apply an external insulation system. However, due to the recent large-scale fires in buildings, the problem of fires in external insulation systems has emerged.

Insulation materials are mostly made of materials that are easily flammable due to the characteristics of performance, so when a fire occurs, the fire easily transfers to the insulation material that covers the entire building, and there is a problem that the fire spreads throughout the building, leading to a large-scale personal accident.

Accordingly, PF insulation, a semi-incombustible material, called phenolic foam, is in the spotlight, but it causes a considerable burden on construction costs due to problems in the construction method and very expensive.

Glass wool, which is a semi-incombustible material such as PF insulation material, is very vulnerable to moisture, so if it is installed outside a building where moisture leaks frequently, when the glass wool retains moisture, a sagging phenomenon occurs, which sharply degrades the insulation performance.

In addition, most semi-incombustible insulation materials require the installation of a separate structural frame to attach the exterior finishing material when installed on the exterior of a building, unlike general styrofoam type insulation materials, which have a soft structure and are hard. In addition, when the exterior finishing material is a finishing material that does not have a waterproof function, there is a disadvantage in that it must go through a process in which a separate waterproof paper must be attached.

Accordingly, there is a need for a technology capable of improving the thermal insulation performance and fire prevention performance between unit units capable of overcoming the above problems.

An object of the present invention is to provide a prefabricated building using a composite insulation panel having a fire protection section in order to solve the above problems.

In order to achieve the above object, according to an aspect of the present invention, four vertical frames for forming a wall surface of a prefabricated building, and four vertical frames for forming an upper surface by interconnecting one end of each of the vertical frames adjacent to each other. A plurality of unit units each including a horizontal frame and four horizontal frames for forming a lower surface by interconnecting the other ends of each of the vertical frames adjacent to each other; Wall panels installed on the frame to form the wall surface of the prefabricated building; For the exterior insulation of the prefabricated building, at least one composite insulation panel installed on the exterior wall of the wall panel; And an airtight fire protection tube disposed between two unit units positioned side by side in an up-down direction or a left-right direction, and having at least one of an air layer and a filling layer therein.

In addition, according to another aspect of the present invention, four vertical frames for forming a wall surface of a prefabricated building, four horizontal frames for forming an upper surface by interconnecting one end of each of the vertical frames adjacent to each other, and each other A plurality of unit units including four horizontal frames for forming a lower surface by interconnecting the other ends of each of the adjacent vertical frames; Wall panels installed on the frame to form the wall surface of the prefabricated building; For the exterior insulation of the prefabricated building, at least one composite insulation panel installed on the exterior wall of the wall panel; And it is disposed between two unit units located side by side in the vertical direction or the left and right direction, it provides a prefabricated building including a fire protection barrier made of a refractory material.

According to the present invention, by arranging the composite insulation panel in the prefabricated building to have a fire compartment using a fixing material, there is an effect of preventing the fire from spreading to the entire building even in the event of a fire.

In addition, the composite insulation panel has the advantage of not having to attach a separate structural frame or waterproof paper for attaching the exterior finishing material, since it is possible to attach the exterior finishing material to the panel itself.

When constructing a prefabricated building on site of a unit unit of a conventional prefabricated building, it is possible to overcome the problem of deteriorating the insulation performance and fire prevention performance of the unit unit due to the gap value formed between the unit units.

In addition, when a plurality of unit units are vertically stacked, insulation performance and fire prevention performance between unit units can be improved.
