Description

Prefabricated Wall Structure

The present invention relates to a wall structure used in prefabricated buildings, and more particularly to a prefabricated building wall structure that can exhibit the effect of traditional houses while maximizing the soundproofing, fireproofing and single effect of the steel house using steel plate.

Conventional prefabricated walls have been made by interposing foamed polystyrene in a space between an inner wall and an outer wall for sound insulation and insulation.

In this conventional structure, the foamed polystyrene causes condensation due to the temperature difference at the contact surface between the inner wall and the outer wall to promote corrosion of the iron plate constituting the inner wall and the outer wall, and cannot maintain sufficient strength structurally, and above all, for fire protection. It was not suitable as a wall.

In addition, prefabricated walls made of simple insulation alone cannot meet the consumer's various requirements for products that can exhibit new functionality, effectiveness and strong durability.

This is because the development trend of the prefabricated wall simply pursues the purpose of satisfying the insulation effect and the sound insulation effect, and it is not possible to combine the lack of durability and fire protection and the excellent characteristics of the traditional house to the modernized prefabricated building. It is due to the point.

The present invention forms a flame retardant and nonflammable material having excellent condensation inhibiting effect in the space between the inner wall and the outer wall, solving problems such as condensation phenomenon and fragility of the conventional prefabricated wall, and prefabricated and traditional by incorporating ocher soil. It can provide the same effect as the structure of the house, it is to provide a structure of the wall beneficial to the human body by using the far infrared rays emitted from the ocher soil.

Far infrared rays have improved thermal efficiency compared with conventional convective and conduction transmission, and the heating part is used as a means to achieve not only high value of heating value but also energy saving and comfort of the house. As it has the characteristics of improving the blood flow of the metabolism of the human body, in particular, the domestic loess soil has excellent components and functions worldwide.

Therefore, if the ocher soil is applied to the building wall by finding a means for reducing the good thermal conductivity and hygroscopicity of the ocher soil itself, it will provide a wall that can satisfy the effect of the insulation effect and far-infrared emission.

It is possible by mixing rice straw with ocher soil as a means for achieving the heat insulation and moisture-proofing effect of such ocher soil.

1 is an exploded perspective view of an embodiment of the present invention.

2 is a longitudinal cross-sectional view of an embodiment of the present invention.

3 is a cross-sectional view of an embodiment of the present invention.

Structural features for achieving the intended purpose of the present invention is to form a prefabricated wall in which sound insulation and insulation is formed between the inner wall and the outer wall, the sound insulation and insulation is formed to form a gap between the inner wall and the outer wall The soil, such as ocher, is filled into the space between the reinforcing frame and the reinforcing frame formed at appropriate intervals.

The filler is to prevent sound insulation, insulation and condensation, and may be selected from foamed urethane or rock wool.

Foamed urethane can especially satisfy the wall for fire prevention.

Soil itself is a material that can be used in construction because it absorbs moisture in humid air conditions and releases moisture in dry air conditions, and it can achieve the best effect on soundproofing and humidity control. It is preferable to use ocher for the purpose, but the ocher soil has very good thermal conductivity, so that it is not possible to obtain satisfactory insulation effect by itself, and because the strength of breaking is weak, the binder is used to improve the insulation effect and strength and binding strength. It becomes more preferable to use what mixed and mixed.

The binder may be in the form of a synthetic resin material, preferably straw straw is used as in the conventional construction method in traditional houses.

When described in detail by the accompanying drawings an embodiment of the present invention as follows.

In the figure, reference numeral 1 denotes an inner wall body, and 2 denotes an outer wall body.

The inner wall 1 is composed of a gypsum board 3, an iron plate 4, and a finishing paper 5, and the outer wall 2 is composed of a gypsum board 6 and an iron plate 7.

The inner wall 1 and the outer wall 2 can be composed of a wall having an arbitrary structure that takes various forms from the known wall structure, in which the iron plates 4 and 7 are made of plywood as desired. It may be replaced.

A reinforcing frame 8 is formed between the inner wall body 1 and the outer wall body 2.

The reinforcing frame 8 is produced by bending a steel sheet in a roll forming machine, and supporting protrusions 9 for increasing contact area are formed at four corners of the surface contacting the gypsum board 6, 7. , The groove 10 may be formed on the outer surface to improve the strength, and the filler 11 for thermal insulation and sound insulation is formed therein.

The groove 10 brings about an improvement in strength due to hardening appearing in the metal structure of the steel sheet and an improvement in compressive strength due to the structural shape when bending the steel sheet material.

Filler 11 is to fill the rock wool or foamed urethane, this filler 11 is able to prevent condensation on the contact surface.

The reinforcing frame 8 is self-supporting at an appropriate interval by the interval retaining hole 13 fixed to the screw 12 on the side.

A plurality of through holes 14 are perforated on the upper surface of the spacing holder 13 so that the soil to be described later can pass through the gap.

The spacing holder 13 can be fixed in one line or two lines according to the width of the wall. In FIG. 1, the spacing holder 13 is constructed in one line, and in FIG. 3, it is shown in two lines.

The ocher soil 15 is interposed in the inner space of the wall formed by the inner wall 1, the outer wall 2 and the reinforcing frame 8.

The present invention may form the support member 16 to reinforce the strength at the portion where the loess soil 15 is located between the inner wall 1 and the outer wall 2.

The support member 16 may be made of wood, resin, steel, or the like, and fastening elements such as screws 17 and the like, with both ends contacting the inner surfaces of the inner wall 1 and the outer wall 2. Is fixed.

Looking at the state in which the prefabricated building wall of the present invention is constructed as follows.

The prefabricated building wall of the present invention may be installed by a known construction method installed on the runner of the horizontal frame in which the wall is placed, although not shown in the drawing.

At this time, the reinforcing frame 8 is supplied while the filler 11 is filled and placed at an appropriate interval by the gap holder 13, and then the support board 16 is placed on both sides of the gypsum board 3 in the width direction. 6) is fastened to the reinforcing frame 8 by fastening the screws 12a, and the supporting member 16 is fixed between the inner wall 1 and the outer wall 2 with screws 12b.

Then the ocher soil 15 is filled in the space formed by the reinforcing frame 8 and the gypsum board 3, 6.

In this state, by attaching the iron plate (4) (7) and the finishing paper 5 to the outside of the gypsum board (3) (6) to form the inner wall (1) and the outer wall (2) to complete the construction.

The present invention can improve the durability of the wall by the reinforcing frame (8), while the filler 11 made of rock wool or foam urethane can prevent heat condensation and sound insulation as well as condensation inside the wall. In particular, when the filling material 11 is used as rock wool, it can satisfy the conditions as a fire-proof wall, and by injecting ocher soil, an excellent heat insulation effect and humidity control of the room are made naturally, and the image of a traditional house in a prefabricated building made of metal is made. The effect is to plant.
