Description

Steel door with strengthen airtight}

The present invention is a steel door with enhanced airtightness, and more specifically, it inserts a rubber pad such as a '지는' shape that has excellent heat transfer and shock resistance between the front and rear steel plates and the inner bone steel plate. It is related to a steel door with improved airtightness along with the performance of prevention of condensation and improvement of soundproofing, windproofing, heat insulation, etc.

In general, the steel door is integrated with the welding 80 and the mullet folding 90 when joining the inner bone iron plate 60 and the front and rear iron plate 30, 40 as shown in Figures 1 and 3 Let's do it. However, the steel door manufactured in this way does not prevent condensation due to temperature difference between inside and outside, and it is only general level in soundproofing, windproof, and insulation performance, and therefore it cannot be used where high airtightness is required. It is only used for general purposes. However, these days, the development of building technology and the improvement of living standards are urgently demanding higher performance steel doors, but they have not been able to meet the demands yet. Because of this situation, in recent years, the conventional steel door is partially complemented to improve the condensation prevention, soundproofing, and wind-proof function, some products have been introduced, but the fundamental solution has not been proposed.

In the case of the conventional steel doors, the reason why the condensation prevention, soundproofing and windproof function is remarkably inferior is that the structure to perform the buffer function is very weak in the combined structure of the four steel doors. There is no provision for the entry of cold air outside into the gap. That is, between the conventional steel door and the door frame, there is a problem in that airtightness such as condensation phenomenon, soundproofing, windproof, etc. as the outside cold air enters into the room between the space inevitably generated to open and close the steel door. As described above, the conventional steel door has a fabrication problem of integrating the internal bone iron plate 60 and the front and rear iron plate 30 and 40 by welding 80 and the mullet folding 90, but to open and close the iron door. There are also significant problems caused by the direct transfer of external air into the room between the space between the doorframe and the steel door. As a result of the wind, indoor wallpaper and floorboards adjacent to the steel doors are entangled with cold outside air from the outside and warm air from the outside, causing the wallpaper to break down or change color within a year or two. The problem of the situation is coming out tremendously.

Accordingly, the present invention is to fundamentally solve the above problems, by inserting a wing pad, such as a '자' shape that has excellent heat transfer and shock resistance between the front and rear iron plate material and the internal bone plate steel plate material to the outside and The aim is to provide steel doors with particularly tight airtightness with the prevention of condensation and the improvement of the performance of soundproofing, windproofing and insulation.

As such, the purpose of the present invention is to prevent condensation due to temperature difference between the inside and outside of the steel door and to dramatically improve the performance of soundproofing, windproofing, heat insulation, and the like. The purpose is to provide a steel door suitable for the place, especially when used as a steel door directly in contact with the outside air to prevent the phenomenon of inflow of air in order to provide a suitable environmental maintenance and comfortable indoor space for the interior.

'The inner bone iron plate bent in a shape (6) is provided with a predetermined interval space portion 10, but it comprises a binding means for inserting a reinforcement pad (9) such as rubber in the interval space portion (10) It is characterized by.

The binding means of the present invention is a screw or rivet in a state in which the insulation space reinforcing pad 9, such as rubber or double-sided tape, which has excellent heat transfer blocking and seismic resistance, is inserted in at least four locations. 11) has a structure that is fastened with the back.

In addition, the biggest feature of the present invention is the contact space portion 7 after forming the contact space portion (7) between the both ends of the front plate 3 and the airtight steel plate 5 is engaged with each other. It can be said that the blade-shaped pad 8, such as a '⊥' shape, is inserted into and inserted between the gaps.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

Figure 4 is a cross-sectional view of the steel door and the steel door frame according to the present invention, Figure 5 is a partial cutaway perspective view of the steel door according to the present invention, Figure 6 is an enlarged cross-sectional view showing several embodiments of the steel door according to the present invention, Figure 7 is a longitudinal sectional view showing various embodiments of the wing pad 8.

The present invention relates to the steel door formed as the internal bone plate and front and back plate. In addition, the present invention is composed of a structure that is further reinforced the portion not described in the contents of the patent application 2002-28691 proposed by the applicant. And the conventional steel door is formed as the internal bone plate and the front and rear steel plate, when joining them are generally integrated by the welding 80 and the mulberry folding (90) method, but in this case condensation prevention and soundproof, windproof, heat insulation It is very difficult to improve such functions.

Therefore, the present invention, in forming the iron door (1), in addition to having the inner bone iron plate (6) and the front and rear iron plate (3) (4) is further provided with an airtight iron plate (5) When combining them, the inner framed steel plate 6 and the front end of the front plate 3 is partially isolated to form a contact space (7), and the '⊥' shape between the isolated contact space (7) The main feature is to insert the wing pad 8 of the back.

According to the present invention, the front plate (3) is bent into a '''shape, the steel plate for confidentiality (5) is' Bent into shape. And the support body (8b) of the wing pad (8) is spaced between the internal bone plate 6 and the front and rear plate (3) (4) and the airtight steel plate (5) space portion 10 And then inserted into the front and rear steel plates by allowing the wing pieces 8a of the wing pads 8 to bulge between the contact space portions 7 of the front plate 3 and the airtight steel plate 5. The heat and vibration transfer generated between the ash (3) (4) and the steel door frame (2) is to be fundamentally reduced.

In addition, according to the present invention, a rubber material or both sides of the front and rear steel sheet material (3) (4) and the airtight steel sheet material (5) and the inner frame iron plate material (6) is separated from each other and installed in the gap space portion 10 generated The reinforcement pad 9 having excellent heat transfer blocking and shockproof functions, such as a tape, is inserted, but may be installed on the same line as the wing pad 8 or may be installed on the rear surface of the wing pad 8. That is, as shown in (a), (b) and (c) of FIG. 6, the support main body 8b of the wing pad 8 is provided in the space space part 10 around the contact space part 7. Separate reinforcement pads on the left and right sides of the wing pad (8) by forming the support body (8b) of the wing pad (8) long or short the length of the support body (8b) without a separate reinforcement pad (9) (9) may be installed side by side, or a reinforcement pad 9 may be attached to the rear portion of the wing pad 8.

In addition, the wing piece 8a of the wing pad 8 may be implemented in various ways. That is, as shown in FIG. 7, the wing pieces 8a may be formed to spread left and right about the support body 8b, and the wing pieces 8a may be thinned to form a plurality of strands. When the support body 8b and the reinforcement pad 9 of the wing-shaped pad 8 in which the wing piece 8a is formed in the space 10 are formed together, the airtightness of the steel door 1 is greatly improved. That is, outside air temperature, shock, vibration, and external noise transmitted from the front plate 3 and the airtight steel plate 5 will be significantly alleviated through the reinforcement pad 9, and the steel door 1 and the steel plate. Outside air temperature or external noise coming in between the door frame 2 will be significantly alleviated through the wing piece 8a of the wing pad 8. In addition, the spacing space portion 10 naturally generated between the above-described iron plate (between 3, 4, 5 and 6) will also have some effect of buffering the temperature, impact, and external noise of the outside air.

And since the support body 8b of the wing pad 8 is installed in close contact with the contact space 7 and the space 10, it is not necessary to take a separate fixing method, but in some cases fixed with an adhesive or the like As a method of fixing the reinforcing pad 9, it is also possible to bind the screw or the like in addition to the rivet 11, and the rivet 9 or the screw is preferably used in a material that does not corrode. Do. In addition, the wing pad 8 and the reinforcement pad 9 may be made of a resin material, a silicone, or a rubber material. However, it is preferable to select a material that is soft and excellent in airtightness, heat insulation, cold protection, and sound insulation. something to do.

In addition, according to the present invention, the airtight airtight air column 5a formed on one side of the airtight steel plate 5 is closed when the door is closed as in the case of FIG. 4. 2) It is inserted into the rubber packing 12 attached to 2) to ensure a high level of airtight stably to meet the required performance of condensation prevention and soundproofing, windproof, heat insulation and the like.

In addition, the wind turbine (5a) refers to the auxiliary device to the upper and lower sides of the door to prevent the wind coming into the door gap, this wind tunnel (5a) is able to withstand long-term use to enhance the function of confidentiality It may be necessary to form a stainless material or a material having equivalent properties.

Reference numeral 13 denotes a material filled inside the steel doors 1 and 10 as an internal filler such as urethane or glass wool, and 14 is a door lock.

Thus, the present invention, the space between the front and rear steel plate (3) (4) and the airtight steel plate (5) and the inner bone iron plate (6) for airtightness for the prevention of condensation and sound insulation, etc. (10) is formed to insert the reinforcement pad (9) and at the same time to form a contact space (7) at the ends of the front plate 3 and the airtight steel plate (5), the contact space ( 7) By inserting the wing pad (8) in between it will be very noticeable that the airtightness, such as condensation prevention and soundproofing greatly improved.

That is, in the conventional case by welding the front plate 30 and the back plate 40, at the same time forming both ends of the front plate 30 and the rear plate 40 to be a mulsel folding (90) As it is assembled, no matter how much high quality insulation materials such as urethane or glass wool are filled in the steel door, the heat of the outside air is transferred to the inside of the steel door and between the steel door and the steel door frame. In addition, when the door is closed as shown in FIG. 1, the outer surface of the rubber packing 12 and the steel door 10 attached to the steel door frame 20 is rotated against each other, so that the airtightness is greatly degraded when used for a long time. There was this.

However, according to the present invention, by forming the reinforcement pad 9 in the space portion 10, the maximum condensation or control problems such as condensation problems and noise and vibration that occur mainly at the four sides of the steel door (1) Not only can the effect be achieved, but also the winds coming into the door gap between the steel door (1) and the steel door frame (2) by bulging the wing pieces (8a) of the wing pad (8) between the contact space (7). As it adopts a structure that can be suppressed, it will have the action and effect to prevent condensation and to minimize the effects of external noise and wind pressure. And the wing piece (8a) itself does not work very badly when opening and closing the door, and the wing piece (8a) is made of a soft material will flow smoothly without any problem.

For reference, the internal and external temperatures of the ⓐ, ⓑ, and ⓒ parts shown in FIG. 4 are shown. If the outside air temperature of the ⓐ part measured in the cold winter is about 10 degrees below zero, the ⓑ part is approximately 3 to 4 degrees. The internal temperature of part ⓒ is room temperature around 20 degrees. Therefore, when the cold outside temperature staying near the door is in contact with the warm air inside, the internal warming effect is further reduced, and condensation is caused. There is a problem that causes deterioration. However, according to the present invention, since the ⓑ part whose internal and external boundaries are unclear is disappeared, the cold air of the ⓐ part is completely blocked by the wing pad 8 such as the '⊥' shape, and is hardly transmitted to the ⓒ part. The blocking effect of internal and external air can be established very reliably.

The present invention is not limited to the embodiments described, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and technical scope of the present invention.

According to the above configuration and action, the present invention forms a wing pad (8) in the contact space 7 of the steel door when the door is closed between the steel door (1) and the steel door frame (2) wing pad ( By blocking the wing piece 8a of 8), it prevents cold or hot outside temperature from entering the room and at the same time, it prevents condensation and almost no problems such as external noise and wind pressure by blocking the inside and outside completely. . In addition, the gap between the front steel plate and the inner bone steel plate and the inner space between the gap portion 10 having a buffer function and the heat transfer reinforcement pad (9) is formed to effectively block the external heat transfer to prevent condensation, soundproofing, windproof, outside air blocking There is even the effect that it can respond appropriately to the place which requires the performance of heat insulation.

In the case of the conventional steel doors, problems such as breakage of internal finishing materials due to condensation, discoloration, and bad smell caused by mold, etc. were significant, but in the case of the present invention, the steel doors of the present invention had high It has a useful effect that can be suitably used as a front door in a poor environment such as various mechanical rooms, wind rooms, coastal apartments, etc., where soundproofing, windproofing, heat insulation, and condensation prevention performance are required.
