Description

Technical Field

[0001] The utility model relates to the technical field of heat insulation strips, in particular to a waterproof heat insulation strip. Background Art

[0002] The thermal insulation strip is the core component of the through-strip thermal insulation profile. It is the "broken bridge" on the heat transfer path of the aluminum profile, reducing the heat transfer in the aluminum profile. It is also a structural connector for the aluminum profiles on both sides of the thermal insulation profile. Through its connection, the three parts of the thermal insulation profile become a whole and bear the load together. High-end aluminum alloy doors and windows require the use of thermal insulation strips.

[0003] At present, when the existing insulation strips are used on rainy days, when the wind blows on the doors and windows, the insulation profiles in the doors and windows will bend, so that the insulation strips are subjected to force, resulting in a decrease in their sealing performance, and then penetration occurs. The penetration of water causes the indoor humidity to increase, which promotes the growth of mold and affects the indoor air quality. Therefore, the present application provides a waterproof insulation strip to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0024] The following is a detailed description of a waterproof and heat-insulating strip provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0025] like Figure 1 and Figure 3 As shown, an embodiment of the utility model provides a waterproof heat-insulating strip, comprising: an aluminum material 1, a slot being provided on the inner side of the aluminum material 1; a heat-insulating strip body 3, inserted and arranged on the aluminum material 1, for reducing heat transfer in the aluminum material 1; a plurality of first barrier strips 9, arranged on the aluminum material 1, for waterproofing the heat-insulating strip body 3; a plurality of second barrier strips 10, arranged on the heat-insulating strip body 3, and the first barrier strip 9 being located above the second barrier strip 10, for preventing rainwater from penetrating; a cavity 8, arranged between the first barrier strip 9 and the second barrier strip 10, for providing an internal and external pressure difference.

[0026] By setting the first blocking strip 9, the first blocking strip 9 is in contact with the insulation strip body 3. In the case of no wind or light wind, rainwater is prevented from directly entering the cavity 8 between the aluminum material 1 and the insulation strip body 3, and the inside of the cavity 8 is kept dry. The probability of rainwater penetration is reduced by physical blocking, thereby ensuring the water tightness and overall sealing performance of the door and window structure; by setting the second blocking strip 10, the second blocking strip 10 is in contact with the aluminum material 1. In windy or extreme weather conditions, when the first blocking strip 9 fails to completely block all rainwater, the second blocking strip 10 serves as a supplementary protective measure to intercept rainwater that bypasses the first blocking strip 9 again.

[0027] When the wind blows over the surface of doors and windows, the first blocking strip 9 and the second blocking strip 10 will accelerate the wind through the gap between the blocking strips. According to Bernoulli's principle, the static pressure of the fluid will decrease accordingly where the flow rate is accelerated. This means that when the wind blows obliquely on the doors and windows, a local low-pressure area may be formed between the blocking strip and the surface of the doors and windows. In the windy state, the air pressure in the cavity 8 can be lower than the external atmospheric pressure. When rain is blown toward the doors and windows by the wind, due to the existence of the air pressure difference, it is more difficult for rain to enter the cavity 8. Most of the rain will be blown through the blocking strip by the wind, and it is difficult to enter the cavity 8 against the air pressure difference.

[0028] like Figure 1 and Figure 2 As shown, it also includes: a plurality of card blocks 2, which are arranged on the insulation strip body 3; a plurality of support plates 6, which are arranged between the insulation strip bodies 3, and the upper and lower sides of the support plates 6 are U-shaped, and the support plates 6 match the card blocks 2.

[0029] By setting the card block 2, the insulation strip body 3 can be supported and fixedly connected, thereby improving the supporting effect of the insulation strip body 3; irregular-shaped plug blocks are set on the left and right sides of the insulation strip body 3, and a card groove is set on the inner side of the aluminum material 1 to match the plug block. The plug block can be made of elastic materials such as rubber, and has good rebound and compression effects.

[0030] like Figure 1 and Figure 2 As shown, the plurality of support plates 6 and the heat insulation strip body 3 are divided into three cavities. By setting up three cavities, polyurethane foam or polyethylene foam can be filled respectively, which have excellent heat insulation performance, are lightweight and have moderate cost. The heat insulation strip body 3 made of foam material forms a continuous honeycomb structure inside, which greatly reduces the thermal conductivity.

[0031] like Figure 1 and Figure 2 As shown, it also includes: a sealing layer 4, which is arranged between two supporting plates 6; and a plurality of sound insulation plates 7, which are arranged between the two supporting plates 6, and the sound insulation plates 7 are staggered in an upper and lower manner.

[0032] By setting the sound insulation boards 7, the staggered distribution of the sound insulation boards 7 can form multiple sound wave propagation paths. When the sound propagates between the sound insulation boards 7, the sound wave energy will gradually be converted into heat energy during the repeated refraction and reflection of the sound waves between different media, thereby consuming part of the noise energy.

[0033] like Figure 2 , Figure 4 and Figure 5 As shown, it also includes: a buffer portion 5, which is arranged on the clamping block 2 and the supporting plate 6.

[0034] By providing the buffer portion 5, when the insulation strip body 3 is subjected to external pressure or extrusion, such as expansion or contraction of the material due to temperature changes, or deformation due to external force, the buffer portion 5 can be elastically expanded and contracted through the first tension spring 52 and the second tension spring 56 in the first movable groove 51 and the second movable groove 55, thereby absorbing and dispersing stress, preventing pressure from being directly transmitted to the aluminum material 1, and avoiding irreversible deformation or damage of the aluminum material 1 or the insulation strip body 3 due to excessive pressure.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, the buffer portion 5 includes: a first movable groove 51, which is arranged on the block 2; a first tension spring 52, which is arranged in the first movable groove 51; a first elastic semicircular rod 53, which is movably arranged in the block 2, and the outer side of the first elastic semicircular rod 53 extends into the first movable groove 51; a second movable groove 55, which is arranged on the support plate 6; a second tension spring 56, which is arranged in the second movable groove 55; a second elastic semicircular rod 54, which is movably arranged on the support plate 6, and the outer side of the second elastic semicircular rod 54 extends into the second movable groove 55.

[0036] Through the first tension spring 52 and the second tension spring 56, when the first elastic semicircular rod 53 moves, the first tension spring 52 is deformed, thereby providing a pulling force for the first elastic semicircular rod 53 to be reset. The second elastic semicircular rod 54 moves, driving the second tension spring 56 to be deformed, and the second tension spring 56 provides a thrust for the second elastic semicircular rod 54 to be reset.

[0037] like Figure 2 , Figure 4 and Figure 5 As shown, the first elastic semicircular rod 53 is in contact with the second elastic semicircular rod 54 .

[0038] By setting the first elastic semicircular rod 53 and the second elastic semicircular rod 54, they move in the first moving groove 51 and the second moving groove 55 respectively. When they are subjected to pressure, they can move smoothly along the first moving groove 51 and the second moving groove 55, so as to adapt to the slight changes between the insulation strip body 3 and the aluminum material 1 and maintain the tightness and stability of the connection; the first tension spring 52 is fixedly connected to the first elastic semicircular rod 53, and the second tension spring 56 is fixedly connected to the second elastic semicircular rod 54. The first elastic semicircular rod 53 moves, causing the first tension spring 52 to deform, and the second elastic semicircular rod 54 moves, causing the second tension spring 56 to deform.

[0039] The technical solution provided by the utility model is to insert the insulation strip body 3 into the aluminum material 1, and fill the divided cavity. When it rains and there is no wind, the first blocking strip 9 prevents rainwater from entering. When there is wind, the rainwater is blown obliquely by the wind, so that part of the rainwater is blocked by the first blocking strip 9, and the other part of the rainwater enters the cavity 8. Since the air pressure in the cavity 8 is lower than the external air pressure, most of the rainwater cannot enter the cavity 8 through the first blocking strip 9. A small amount of rainwater enters and is blocked by the second blocking strip 10, and is discharged through the drainage channel set on the aluminum material 1.

[0040] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
