Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shutter having insulator manufacturing method,

The present invention relates to a method of manufacturing a heat insulating shutter having a heat insulating material, and more particularly, to a method of manufacturing a heat insulating shutter having a heat insulating material, The front and rear members are spaced apart from each other by the heat insulating material to prevent the warm and cool air from being introduced into the room. In particular, when the shutter is opened or closed, the heat insulating material is prevented from being detached from the slats The present invention relates to a method of manufacturing a heat-insulating shutter, which is provided with a heat-insulating material that is easy to secure a space when a shutter is formed by reducing the volume of a shutter when the shutter is wound.

A shutter equipped with a shaft is installed in a building such as an airplane hangar, a power plant, a factory, a plant, and the like. Such a shutter serves to open or close an entrance of a building or a facility, And the door is opened or closed by raising or lowering the shutter, that is, raising or lowering the shutter.

Specifically, the above-described shutter is structured such that the slats made of aluminum or the like are continuously vertically combined and lifted or lowered while being wound or unwound on a shaft mounted on a shutter box on the upper portion of the guide rail, thereby opening or closing the shutter .

The shutter may include a plurality of narrow and long slats, a driving motor provided close to one side of the slats to provide a driving force for raising and lowering the slats, and a motor connected electrically to the driving motor, A switch box provided with an operation switch for reverse rotation, a guide rail formed vertically along both side edges of the slat and guiding the upward and downward movement of the slat, And a shaft to be lowered.

In the case of such a shutter, a heat insulating material is inserted into the slat for keeping the interior of the building warm during the winter season, or a separate heat insulating means is provided on the outer surface to prevent the cold wind from entering the room from the outside.

However, it is extremely difficult to insert and fix the insulator in the inner space of the slat so as to be completely filled, and there is a problem that the process cost increases. In order to solve this problem, there has been developed a technique of foaming and molding an insulation material in a slat, but it is impossible to securely fill the space inside the insulation, and heat is transmitted through the slat panel in both the insulation- There is a problem that can not solve the fundamental heat loss problem.

Particularly, the general structure of the above-described slat is a one-piece type in which the front and rear members are formed by a predetermined distance from each other, that is, the hollow is hollow and the front and rear members are connected to each other by two or more connecting portions . However, in the case of the winter season, the cold air is transferred to the rear member through the connection portion by the heat conduction on the front member in the case of the summer season, and the transferred cold air and warm air are directly transferred to the room, There was a problem of wasting rain.

Therefore, in order to solve such a problem, a heat insulating material or the like is interposed between the front and rear members, but it has been difficult to significantly affect the above-mentioned reduction in the heating and cooling costs.

Patent No. 10-1315965

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a heat exchanger which is formed by separating front and rear members, And a heat insulating material for preventing the front and rear surface members from being separated from each other by the heat insulating material so as to prevent warmth and cool air from being introduced into the room from outside, and a method for manufacturing the same.

It is a further object of the present invention to provide a heat insulating material which can prevent the heat insulating material from being detached from the slats even when the shutter is frequently moved when the shutter is opened and closed and to reduce the volume of the shutter when the shutter is wound, And an object of the present invention is to provide a heat insulating shutter and a method of manufacturing the same.

According to an aspect of the present invention, there is provided an adiabatic shutter having a slat (100) coupled in series, wherein the slat (100) is divided into a front member (110) and a rear member (120) The front member 110 and the rear member 120 are spaced apart from each other by a predetermined distance and the front member 110 and the rear member 120 are separated from each other by the heat insulating material 200, And the slat (100) constituting the member (110) and the rear member (120) are separated and fixed.

The heat insulating material 200 is interposed between upper and lower portions of the front member 110 and the rear member 120 so that the heat insulating member 200 is inserted into the upper and lower portions of the slats 100, (200) is built in.

In one embodiment, between the front member 110 and the rear member 120, protruding pieces 111 and 121 protruding to be opposed to each other are provided, and a tape connecting the protruding pieces 111 and 121 A protruding piece 121 of the rear surface member of the protruding pieces 111 and 121 is attached to the inner surface of the rear member 120 (122, 123) are formed at the upper end of the rear member (120).

In one embodiment, the rear member 120 includes a protrusion 121 and a vertical portion (not shown) formed at an upper portion and a lower portion of the outer surface of the outer surface, which are separated from the inner surface of the rear member 120, And a buffer part 125 formed as an empty space is formed on the back surface of each of the vertical parts.

Another aspect of the present invention is to provide an ink jet recording head which is formed by extrusion molding and is formed in two layers and partitioned into upper, middle and lower spaces 101, 102 and 103 by first and second partition walls 141 and 142, respectively. And the upper and lower ends of the vertical portion 124 are formed such that the upper and lower spaces 101 and 103 are spaced apart from each other by a predetermined distance Fabricating a slat (100) in which a buffer (125) is formed to be spaced apart; Cutting the intermediate portion of any one of the first and second partition walls 141 and 142 of the manufactured slat 100 to form protruding pieces 111 and 121; Attaching the tape 130 to the protruding pieces 111 and 121; Injecting a liquid heat insulator through the opening of the side to which the tape is attached and curing it; Cutting the intermediate portion of the other one of the first and second barrier ribs 141 and 142 to form protruding pieces 111 and 121; Attaching a tape to the protruding pieces (111, 121); And injecting a liquid heat insulator through the opening of the side to which the tape is attached to cure.

In one embodiment, the tape is a heat insulating tape.

According to the heat insulating shutter having the heat insulating material of the present invention and the method for manufacturing the same, first, the heat insulating material, which is one of the heat insulating materials, is interposed between the upper and lower portions of the slat, So that the cooling / heating ratio can be reduced. That is, the partition walls of the two-layered slats are removed and separated by the front and rear portions, and the heat conduction is interrupted by interposing the heat insulating material in place of the space separated by the partition walls, thereby enhancing the heat insulating effect.

Second, the heat insulating material is prevented from being detached from the slats even when the shutters are frequently moved, and the binding rings formed at the upper and lower portions of the slats are protruded only at the upper and lower portions without protruding to the outside of the rear member. It is possible to secure space when the shutter is constructed.

Third, the protruding pieces of the rear member are formed to be spaced apart from the inner surface of the rear member by a predetermined distance, so that the use of the heat insulating material can be saved while achieving a better heat insulating effect.

The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Further, detailed descriptions of well-known functions and configurations that may be unnecessarily obscured by the gist of the present invention are omitted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, and a heat insulating shutter including the heat insulating material of the present invention and a method of manufacturing the same will be described in detail.

1 is a side view showing a part of a shutter constructed by binding the slats of FIG. 1, FIG. 3 is a front view of the shutter of FIG. 2, and FIG. 4 is a view showing a part of a state in which the shutter is wound.

Referring to FIGS. 1 to 4, the heat insulating shutter having the heat insulating material of the present invention is separated into a front member 110 and a rear member 120 in which a slat 100 is bound in series to form a shutter . The front member 110 and the rear member 120 may be formed in various shapes. Preferably, the front member 110 and the rear member 120 are curved so as to have a predetermined curvature toward the outside, that is, And the rear member 120 are spaced apart from each other by a predetermined distance. Also. A heat insulating material 200 is interposed between the front member 110 and the rear member 120 to keep the front member 110 and the rear member 120 separated from each other. Therefore, the front member 110 and the rear member 120 are fixed by the heat insulating material 200 to constitute the slats 100.

It is preferable that the heat insulating material 200 is interposed between the front member 110 and the rear member 120 at the upper part and the lower part of the front member 110 and the rear member 120. That is, To prevent the phenomenon of being transferred to the member (120) and conducting, while maintaining the structural strength. A heat insulating tape 130 for connecting the protruding pieces 111 and 112 is provided between the front and rear members 110 and 120. The protruding pieces 111 and 121 protrude to face each other, Respectively. Therefore, the tape 130 prevents the heat insulating material from flowing into the middle portion of the slats 100 during curing.

As the heat insulating material 200, various materials can be used. Preferably, a polyurethane material is used. For example, azone insulating material can be used.

Since the heat insulating material 200 serves to connect the front and rear members, a high strength product should be used. For example, the heat insulating member 200 preferably has a tensile strength of 31 N / mm ² or more and an impact strength of 1.01 J / cm or more.

As shown in FIG. 1, the protrusions 111 and 121 may be coupled to the heat insulating material 200 in a state where protrusions 105 are formed. This allows the mechanical strength of the shutter to be maintained due to the protrusion 105. This increases the coupling area of the heat insulating material and the protruding pieces to improve the coupling force and prevent the front and rear members from falling back and forth from the heat insulating material, There is also an effect. In order to prevent the heat insulating material 200 from being separated from the slats 100, it is preferable that the heat insulating material 200 is formed so as to protrude at a predetermined height from an upper end portion and a lower end portion. Therefore, the joining area between the front and rear members 110 and 120 is also widened. For this purpose, protrusions 105 may be formed on the upper end of the front member 110 and the lower end of the rear member 120 to further increase the coupling area with the slats 100. That is, the heat insulating material 200 is entirely filled in the heat insulating material case 270. In addition to the function of preventing the heat insulating material from being released to the outside due to frequent movement of the shutter and vibration due to an external shock, The bonding force between the heat insulating material 200 and the slats 100 is increased by the projections 105.

Here, the protruding pieces 121 of the rear surface member of the protruding pieces 111 and 121 are spaced apart from the inner surface of the rear surface member 120 by a predetermined distance.
Specifically, the slat (100) is formed with two projecting pieces (111) protruding toward the inside of the slat (100), each of which is formed in a curved surface so as to have a predetermined curvature toward the outdoor side, Two protruding pieces 121 protruding toward the inside of the room corresponding to the protruding pieces 111 formed on the front member 110 are formed on the upper and lower sides respectively, And a rear member 120, which is formed to have a predetermined curvature toward the outdoor side between the points spaced at predetermined intervals and located on the indoor side.
In addition, two protrusions formed by the protrusions 111 formed on the front member 110 and the protrusions 121 formed on the rear member 120 are disposed on the upper and lower sides of the slats 100, An opening 170 located in the middle of the lower portion of the heat insulating material case located at the upper and lower portions of the heat insulating material case located at the upper portion of the two heat insulating material cases 270, And a hollow portion 160 positioned in the middle of the upper portion of the heat insulating material case located at the lower and lower portions of the heat insulating material case.
A tape 130 for connecting the protruding pieces 111 and 121 located at the lower portion of the heat insulating material case 270 located at the upper portion of the two heat insulating material cases 270 and the hollow portion 160, (130) connecting the hollow portion (160) with the projecting pieces (111, 121) located on the upper portion of the heat insulating material case (270) And a heat insulating material 200 which is inserted into a space formed by the two heat insulating materials case 270 and the tape 130 and inserted into a liquid state and hardened.

The protruding pieces 121 of the rear member 120 are spaced apart from the inner surface of the rear member 120 by a predetermined distance.

First, it is intended to reduce the use of the heat insulating material 200. Since the heat insulating material 200 is generally relatively expensive, the protruding pieces 121 of the backing member are spaced apart from the inner surface of the backing member 120 by a predetermined distance to form the buffering portion 125, . That is, the buffer part 125 is formed on the rear side of the space where the heat insulating material 200 is housed.

Second, the binding rings 122 and 123 can be formed in the space between the front member and the rear member to minimize the volume when the shutter is opened as shown in FIG. This will be described in detail later.

On the other hand, the buffer 125 functions to secure a space for expansion and contraction because the shutter is expanded and contracted during the winter season and the summer season. Since the front and rear members 110 and 120 are fixed to each other only by the heat insulating material 200 and the heat insulating tape 130 in the absence of the buffer part 125, The front member 110 and the rear member 120 can be separated from each other according to such a change in volume. The buffer part 125 serves as a free space for expansion and contraction of the shutter, .

In addition, binding rings 122 and 123 are formed on the upper and lower ends of the rear member 120, respectively. It is preferable that the upper binding ring 122 and the lower binding ring 123 are formed on the upper and lower portions of the body of the rear member 120. This is for minimizing the volume when the slats 100 are wound. Here, the upper binding ring 122 and the lower binding ring 123 are formed in a shape of a hook having a substantially '' shape, and the upper and lower binding rings 123 and 123 are symmetrically formed on the upper and lower sides so that the hooks are engaged with each other to be entangled with each other.

As shown in FIG. 2, the slats 100 constructed in this manner are connected in series to form a shutter 300, which is installed at an entrance of a building and used. Also, as shown in FIG. 4, when the shutter 300 is wound on a wind-up roll 150 installed on the upper part of the door, that is, the upper end of the shutter, the volume of the shutter 300 is reduced. This is because the binding rings 122 and 123 are not formed to protrude outward from the body of the rear member 120 but are formed to protrude only from the upper and lower portions of the body of the rear member 120, The volume thereof can be remarkably reduced, so that it becomes easy to secure a space at the time of shutter construction.

The rear member 120 is formed with a vertical portion 124 having a vertical section formed at an upper portion and a lower portion of an outer surface of the rear member 120 spaced from the inner surface of the rear member 120 And the vertical portions 124 are concave toward the front member 110.

That is, as shown in FIG. 2, when the front member 110 faces the outdoor side and the rear member 120 is located on the indoor side, when the wind is blown outdoors, the slats 100 are separated from the shutters Since the vertical portions 124 formed on the slats 100 bound to each other are pressurized to the room side but are in contact with each other, the vertical portions 124 can be kept vertical (shown by dotted lines in FIG. 2) .

Hereinafter, a method of manufacturing the heat insulating shutter having the heat insulating material of the present invention will be described.

5 to 10 are views sequentially showing a method of manufacturing a slat provided with the heat insulating material of the present invention.

5 to 10, the first slat is formed by extrusion molding as shown in FIG. 5, and is formed in two layers. The first and second partition walls 141, A middle portion, and a lower portion.

Then, as shown in FIG. 6, the intermediate part of any one of the first and second partition walls 141 and 142 of the manufactured slat 100 is cut to form the protruding pieces 111 and 121. At this time, either one of the first and second barrier ribs 141 and 142 must be removed first, and the two can not be simultaneously removed. For convenience of description, the first barrier ribs 141 formed on the upper portion of the slat 100 will be firstly removed, assuming that the slats 100 are upright. Here, the width of the projecting pieces 111, 121 left in the first or second partition wall occupies about 20-90% of the width of the entire partition wall. If it is less than 20%, the adhesive area of the tape is so small that the tape can hardly bear the weight of the heat insulating material in the curing process. If it exceeds 90%, the distance of both protruding pieces becomes too short and the heat may be conducted.

Then, the tape 130 is attached to the protruding pieces 111 and 121 formed after removing the first partition 141 as described above. It is preferable that the tape 130 be attached with a smooth insulating tape so that the heat insulating material in the liquid state spreads well into the upper space 101 before curing.

Then, as shown in FIG. 7, a liquid insulating material is injected through the opening of the upper space 101, which is the side to which the tape 130 is attached, and is cured for a predetermined time. Here, the heat insulator used in the present invention should be one which is initially in a liquid phase state and hardens as time elapses so that it can have a solid form.

Then, as shown in FIG. 8, the middle part of the second partition 142 is cut to form the protruding pieces 111 and 121.

When the tape 130 is attached to the projecting pieces 111 and 121 and the heat insulating material is injected through the opening of the side where the tape 130 is attached and cured as shown in FIG. Thereby completing one of the slats 100 shown in FIG.
To be more specific, two protruding pieces 111 protruding toward the indoor side are formed on the upper and lower sides, respectively, and formed into a curved surface having a predetermined curvature toward the outdoor side, and a front surface member And two protruding pieces 121 protruding toward the room corresponding to the protruding pieces 111 formed on the front member 110 are formed on the upper and lower sides respectively A vertical portion 124 is formed up to a point spaced apart from the vertical portion and a cushioning portion 125 is formed on the rear surface of the vertical portion on one side so that a section between the vertical portions has a predetermined curvature toward the outdoor side And the first and second partition walls 141 and 142 formed between the front and rear members 110 and 120. The first and second partition walls 141 and 142 are formed by extrusion molding, ) On the upper and lower sides Four protrusions 105 are formed on the protrusions formed on the upper and lower surfaces of the front member and the rear member so as to face the heat insulating material case and the heat insulating material case 270 And a lower portion of the heat insulating material case 270 formed at the lower portion may include a step of forming a slit 100 in which an opening portion 170 is formed so that a heat insulating material is inserted while protruding pieces are formed.
The hollow portion 160 penetrates through the heat insulating material case so as to form the protruding pieces 111 and 121 by cutting the intermediate portion of any one of the first and second partition walls 141 and 142 of the manufactured slat 100, And a tape 130 is attached to the hollow portion 160 between the protruding pieces 111 and 121 formed in any one of the heat insulating materials case 270 having the partition walls cut out from the two heat insulating materials cases 270. [ And inserting the heat insulating material 200 into the space formed by the heat insulating material case and the tape through the opening part 170 formed in any one of the heat insulating material cases to which the tape 130 is attached, . ≪ / RTI >
A hollow portion 160 penetrating through the heat insulating material case is formed so that the intermediate portion of the other one of the first and second partition walls 141 and 142 of the manufactured slat 100 is cut to form the protruding pieces 111 and 121, And a tape 130 is attached to the hollow part 150 between the protruding pieces 111 and 121 formed in the other heat insulating material case 270 having the partition walls cut out from the two heat insulating material cases 270. [ And inserting the heat insulating material 200 into the space formed by the heat insulating material case and the tape through the opening 170 formed in the other heat insulating material case to which the tape is attached .

As shown in FIG. 2, the completed slats 100 are connected in series to form a shutter 300, which is installed at the entrance of a building as shown in FIG.

Since the heat insulating material is disposed on the upper and lower portions of the slats 100, the heat from the lower portion to the upper portion and the cold air flowing from the upper portion to the lower portion are blocked, thereby maximizing the heat insulating effect.

In addition, it is generally aluminum that forms a slat, and since aluminum is a metal, thermal conductivity is very high. Therefore, when the slats are formed of aluminum, it becomes very difficult to properly maintain the heat insulating performance. Therefore, when the partition wall of the aluminum material slat having a high thermal conductivity is cut and the heat insulating material is filled in the thermal conductive material as in the present invention, the slats can not easily transmit external heat and cold air, and the heat insulation is achieved. That is, since the slats are separated into the front member and the rear member, the external warm and cold air is not transmitted to the room by the heat insulating material.
