Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door and window equipment, and particularly relates to a sound-insulating and heat-insulating flat door. Background Art
[0002] As an important part of the building envelope structure, the performance of sound-insulating and heat-insulating doors and windows directly affects the energy efficiency level of buildings and the comfort of the indoor environment. In the current door and window market, there are a variety of sound-insulating and heat-insulating products, but most products still have problems such as single performance and poor comprehensive effect.
[0003] Although there are already various sound-insulating and heat-insulating door and window products on the market, there are still many technical problems in their actual applications. First of all, although some products have certain sound-insulating or heat-insulating performance, it is often difficult to meet the dual standards of high-efficiency sound insulation and good heat insulation at the same time. This is mainly due to the limitations in material selection and structural design, resulting in performance shortcomings of the products. Secondly, although some products use multi-layer composite structures to improve the sound-insulating and heat-insulating effects, due to poor sealing performance, there are problems of energy loss and noise penetration in the actual use process. Content of the Utility Model
[0004] To solve the above problems, the utility model proposes a sound-insulating and heat-insulating flat door, which includes a door frame and a door leaf. The door frame includes two layers of aluminum materials on the inside and outside, and the two layers of aluminum materials are connected by a heat-insulating strip. A sealing groove is opened on the inner side of the door frame, and a sealing rubber strip is installed in the sealing groove. When the door leaf is closed, the door leaf and the door frame form a sealing structure through the sealing rubber strip; the door leaf includes two layers of metal plates on the inside and outside, and the two layers of metal plates are connected by a sound-insulating and heat-insulating layer. The sound-insulating and heat-insulating layer is a multi-layer composite structure, and the sound-insulating and heat-insulating layer includes PU foam and sound-absorbing cotton.
[0005] Furthermore, a door leaf glass is provided on the door leaf. The door leaf glass is a double-layer insulating glass, and argon gas is filled in the double-layer insulating glass.
[0006] Furthermore, the sealing rubber strip is made of ethylene propylene diene monomer (EPDM).
[0007] Furthermore, the sealing rubber strip is made of silica gel.
[0008] Furthermore, the aluminum material of the door frame is broken bridge aluminum.
[0009] Furthermore, a flat door hinge is installed on the door leaf and the door frame as an opening mechanism, and a handle is provided on the door leaf.
[0010] The beneficial effects of the utility model are as follows:
[0011] 1. The use of broken bridge aluminum as the door frame material effectively blocks the direct conduction of heat through the metal, and the heat insulation strip filled between the inner and outer aluminum materials further enhances the heat insulation performance. The door leaf adopts a design of double-layer metal plates clamping a multi-layer composite sound insulation and heat insulation layer. The combination of PU foam and sound-absorbing cotton not only provides excellent sound insulation effect but also enhances the overall heat preservation performance.
[0012] 2. The double-layer insulating glass is filled with argon, which not only ensures good light transmittance but also greatly improves the heat insulation and sound insulation capabilities of the doors and windows. The cooperation of the sealing groove and the sealing strip forms a tight sealing structure when the door leaf is closed, effectively preventing air convection and noise penetration.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0019] The following further describes the present utility model in conjunction with the accompanying drawings of the specification:
[0020] A sound-insulating and heat-insulating French door, as Figure 1 and Figure 2 shown, includes a door frame 1 and a door leaf 2. A French door hinge is installed between the door leaf 2 and the door frame 1 as an opening mechanism, and a handle 4 is provided on the door leaf 2; the door frame 1 includes two layers of aluminum materials 101 inside and outside, and the two layers of aluminum materials 101 are connected by a heat-insulating strip 102. A sealing groove 103 is opened on the inner side of the door frame 1, and a sealing rubber strip is installed in the sealing groove 103. When the door leaf 2 is closed, a sealing structure is formed between the door leaf 2 and the door frame 1 through the sealing rubber strip.
[0021] Among them, the aluminum material 101 of the door frame 1 is broken bridge aluminum, and the sealing rubber strip is made of ethylene propylene diene monomer (EPDM) rubber or silica gel.
[0022] As Figure 1 and Figure 3 shown, in this embodiment, the door leaf 2 includes two layers of metal plates 201 inside and outside, and the two layers of metal plates 201 are connected by a sound-insulating and heat-insulating layer 202. The sound-insulating and heat-insulating layer 202 is a multi-layer composite structure, and the sound-insulating and heat-insulating layer 202 includes PU foam and sound-absorbing cotton; a door leaf glass 3 is provided on the door leaf 2, and the door leaf glass 3 is a double-layer insulating glass, and argon gas is filled in the double-layer insulating glass.
[0023] The working principle of the present utility model is as follows:
[0024] The design of the broken bridge aluminum door frame 1 reduces the direct transfer of heat through the door frame 1 by interrupting the heat bridge effect of the aluminum material 101. With the use of the heat-insulating strip 102, the heat transfer path is further blocked. The combination of the double-layer metal plates 201 of the door leaf 2 and the multi-layer composite sound-insulating and heat-insulating layer 202 forms an efficient sound-insulating and heat-insulating barrier. As the main heat-insulating material, the closed-cell structure of the PU foam effectively prevents air convection and heat conduction; while the sound-absorbing cotton absorbs and attenuates the sound wave energy through its porous structure to achieve the sound-insulating effect. The double-layer insulating glass is filled with argon gas, and the low thermal conductivity of argon gas and the air layer of the double-layer glass structure effectively prevent the transfer of heat and the penetration of sound.
[0025] The sealing design of the sealing groove 103 and the sealing rubber strip forms a tight sealing structure by squeezing the sealing rubber strip when the door leaf 2 is closed, preventing the entry of external air and noise, thus ensuring the quietness and comfort of the indoor environment.
[0026] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
