Description

Composite Doors {Composite Doors}

The present invention relates to a door, and more particularly, to provide a combined door which is capable of simultaneously satisfying both fire resistance and insulation by applying a mortar and a fireproof insulation material to the inside of a door.

Generally, doors used in houses, apartments, offices, factories, etc. are generally made into doors by a combination of metal plates, and the inside of the doors is filled with a honeycomb of honeycomb made of paper and sealed.

In such a door, there is a problem that the honeycomb inside is burned due to the high temperature when the fire occurs, and the outer metal plate is melted and deformed or the mold is deformed, so that the fire spreads easily to the opposite side.

In addition, since it is easy to transfer heat due to the internal space and the metal, it is vulnerable to adiabatic heat, resulting in internal condensation, as well as being vulnerable to noise and windshield.

In recent years, there has been a fireproofing material filled in the form of a foam or board instead of honeycomb inside the door.

This is because the fire resistance and the heat insulation function are improved as compared with the honeycomb application. However, when the high heat caused by fire continues for a long time, there is a problem that the fire resistance insulator alone can not withstand a long period of time.

Registration Utility Model No. 20-0416667.

The present invention has been developed in order to solve the conventional problems mentioned in the background art, and an object of the present invention is to improve the internal structure of a door by using mortar in particular, thereby improving the bearing capacity, heat resistance and heat insulation of the door.

In order to achieve the above object, the present invention proposes that a mortar is poured into a door, and a refractory insulator is formed inside the mortar.

According to the configuration described above, since another solid concrete form frame is constructed inside the door, the supporting force is improved in the entire door, so that the mold of the door is not deformed even if the high heat caused by the fire lasts for a long time, and a complex double application of mortar and fireproof insulation As well as fire protection, insulation, condensation, sound insulation, wind protection and crime prevention functions are significantly improved.

(B) is a cross-sectional view taken from the side of (a), and (c) is a cross-sectional view showing another example of (b) Sectional view.

As shown in the figure, the composite door according to the present invention includes a door 10 made of a metal plate, a mortar 20 filled in the door 10, And a fire-resistant insulating material (30).

The mortar 20 is a typical concrete made of a mixture of cement, water and sand, and provides another solid mold inside the door 10. [

By doing so, it is possible to prevent the metal plate of the door 10 from being deformed due to the high temperature due to the occurrence of the fire, and to prevent the mold from being deformed. have. In addition, the refractory insulation 30 formed inside the mortar 20 can maintain the mold of the mortar 10 and reduce the overall weight of the door 10. In particular, the insulation 20, Fireproof, soundproof, windproof, and condensation can be prevented. Also, the door (10) is not easily damaged by the mortar (20), which is quite advantageous for crime prevention. In addition, it is firmly bonded to the metal plate material and advantageous for airtightness without using any adhesive.

The mortar 20 may be formed only on the inner edge of the door 10 as shown in (b), or may be formed on the entire inner surface as shown in (c). In the case of generally used doors, electrons are preferable for lightening the weight, and the latter is preferable in a place where there is a high possibility of occurrence of a fire, a place to endure a high heat for a long time, and a place where a temperature difference between the inside and the outside is high.

Although not shown in the drawings, another example of the mortar 20 will be described as follows.

The mortar 20 may be made of a mixture of heat-resistant reinforcement materials such as pearlite, steel fiber, glass fiber, polymer and the like.

Particularly, the above-mentioned pearlite is composed of white pearl-shaped wheat particles obtained by pulverizing perchloric acid (a kind of igneous rock) to 8 to 12 mesh or less and heating it rapidly after heating to foam the crystal water contained therein and cooling it, It is made into light spherical small particles having micro voids, and is not ignited due to the nature of the inorganic substance, and can exhibit excellent functions in heat resistance, heat insulation, soundproofing, and wind protection by micro voids.

On the other hand, the steel fibers, glass fibers, polymers, etc. can firmly bind the mortar 20 and improve durability.

It is preferable that the heat resistant stiffener is mixed with perlite alone in the mortar 20 or further added with steel fiber, glass fiber, polymer or the like as necessary.

By doing so, the weight of the mortar 20 layer can be considerably reduced, and the adhesion and durability of the mortar layer 20 can be further improved, as compared with the case where only the mortar 20 is formed singly, and heat resistance, heat insulation, soundproofing, Thereby exerting a more excellent effect.

Although not shown in a separate drawing, in the mortar 20, Filled The refractory insulation 30 will be described as follows.

The refractory heat insulating material 30 may be made of any one of ceramic wool, mineral wool, and glass wool, or a mixture of two or more thereof.

The above-mentioned ceramic wool is a mineral fiber obtained by melting silica and alumina by fibrillating. The fine wool and the fine air layer are formed between continuous fibers to effectively block the heat flow and the raw material itself is inorganic, It is excellent in light weight, heat insulation, absorptiveness, durability, and sound pressure is converted into frictional energy when sound passes through fiber and absorbs sound, so it has good soundproofness. The construction is excellent.

The mineral wool is made of mineral artificial mineral fiber fireproofing material 30 which is formed by melting calcium silicate ore at high temperature (1600 degrees), rotating it at a high speed, forming the fiber into a predetermined shape using a binder. The mineral wool is composed of uniform and fine (5 micron) fibers, and has a high density. Since the air is tightly contained between fine fibers, the mineral wool is excellent in sound absorption and sound insulation effect. It is not deformed even at a high temperature of 700 ° C. It is excellent in flexibility and is not broken easily. It is easy to cut and easy to apply. It does not absorb moisture in the air, so it has excellent weatherability, low thermal conductivity and excellent insulation and insulation.

The above-mentioned glass wool is produced by mixing glass minerals such as sand, feldspar, limestone, etc. with recycled glass, melting them, making fine fibers by a centrifugal method, and bonding them with an organic binder to form a fine air layer between the fibers. Excellent resistance to moisture, durability, heat insulation and sound absorption.

The refractory insulation 30 described above is preferably sera wool, mineral wool, and glass wool in the order of heat resistance and workability.

When the refractory heat insulating materials 30 are mixed, the refractory heat insulating materials 30 may be crushed and mixed, then needle punched, and then formed into a mixed refractory heat insulating material formed into a predetermined shape through a binder.

By doing so, the performance can be further improved as compared with the case of forming the refractory insulation 30 alone.

Therefore, the refractory insulation 30 made of the inorganic fibers has a weight less than that of the conventional foam or board refractory insulator, and is particularly effective in preventing heat insulation, soundproofing, windshield, and condensation. have.

2 is a cross- 1 Panel structure 1 is a cross-sectional view illustrating an embodiment of the present invention with reference to the accompanying drawings.

As shown in the figure, the door 10 of the present invention is made of a metal plate and has a back plate 101 in the form of a box with one side opened, a reinforcing frame 103 constructed along the inner surface of the back plate 101, And a front plate 102 that is bent and coupled to surround the open end of the rear plate 101.

The above-described panel structure is advantageous not only in that the door 10 can be easily manufactured, but also the sealing is excellent and the formwork is robust.

Meanwhile, the reinforcing frame 103 may be selectively removed as needed. That is, according to the present invention, since the mortar 20 is formed on the inner edge of the door 10, the mortar 20 hardens and exerts a better supporting force than the reinforcing frame 103, It can be selectively excluded. When the reinforcing frame 103 is excluded from the door 10, the weight of the door 10 can be further reduced as well as cost reduction.

3, 2, The support wall 1 is a cross-sectional view illustrating the structure of a semiconductor device according to an embodiment of the present invention.

As shown in the drawings, the present invention may constitute a support wall 40, which is connected in a rim shape so that the front and rear surfaces of the door 10 are connected to each other between the mortar 20 and the refractory 30.

It is preferable that the support wall 40 has a durability enough to hold the mold of the mortar 20 and is capable of preventing fire and heat transfer. Examples of the material include inorganic fire-resistant and heat-insulating boards, heat-resistant synthetic resins, and the like.

In this way, it is possible to facilitate the placement of the mortar 20 and the partitioning of the section into the inside of the door 10 and, in particular, to effectively prevent the mortar 20 from being deformed before or after the mortar 20 is hardened .

Figure 4 2, Sectional view of a packing, which will be described with reference to the accompanying drawings.

As shown in the drawings, the packing 50 may be applied to a portion where the front plate 102 and the rear plate 101 are in contact with each other.

Preferably, the packing 50 is made of a non-combustible material having a cushion for airtightness and heat shielding. Examples of the material include flame retardant synthetic rubber, chlorinated polyethylene rubber, and the like.

In this way, heat can be prevented from being conducted to the opposite side along the portion where the plate material continues in a fire, and the inside of the door 10 can be tightly closed, so that heat is transmitted to the opposite side during a fire, And the inside of the door 10 is blocked from air communication with the outside, thereby further improving the function of insulation, soundproofing and windshielding as well as preventing condensation.

Beyond the of the present invention described above, those skilled in the art for the present invention appears to be able to determine the right range to receive the spirit and protection to be sought in the present invention from the figure that the specific details and accompanying of the present invention sufficiently, Based on this, various applications and modifications may be usefully used industrially.
