Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy window technology, and in particular to a composite aluminum alloy window with high efficiency in sound insulation and heat insulation. Background Technology

[0002] Thermally broken aluminum alloy doors consist of an inner aluminum alloy door panel and an outer aluminum alloy door panel. The interlayer between the inner and outer aluminum alloy door panels is filled with relevant thermal insulation materials to form a thermal bridge, thus breaking the cold bridge. This thermal break design principle has excellent thermal insulation function and is currently widely used in building energy-saving projects.

[0003] Existing aluminum alloy profiles generally adopt single-cavity or double-cavity hollow structures. Although such designs can meet the requirements of lightweighting and basic strength, they are seriously inadequate in terms of acoustic optimization of the internal space: the single or few cavities inside the aluminum alloy window form a straight sound wave conduction path, and external noise can directly penetrate through the profile cavities, especially lacking effective blocking of mid-to-high frequency noise. At the same time, in order to improve sound insulation performance, some technologies have tried to fill the profile cavities with sound insulation materials (such as rock wool and foam), but the single / double-cavity structure lacks internal support, and the filling is prone to profile deformation, especially in large-size window types, where the profile deflection problem is significant, affecting the opening and closing stability and service life. Therefore, it is necessary to propose a composite aluminum alloy window with high-efficiency sound insulation and heat insulation to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency sound and heat insulation composite aluminum alloy window.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency sound and heat insulation composite aluminum alloy window includes two sets of beams, each with a sound insulation cavity filled with a sound insulation block. Multiple hexagonal through holes are formed on the outer wall of each sound insulation block. The two sets of beams are connected by a thermal bridge. Connecting grooves and connecting edges are provided on the outer wall of each beam, engaging with each other and used for connecting the beam to other components. Sliding grooves for installing sliding components are provided on each beam. Sealing edges are provided on the edges of each beam. Multiple sets of support columns are arranged alternately at an incline within the sound insulation cavity, and are hollow inside.

[0007] Preferably, the sound insulation block is integrally formed from porous sound-absorbing material, and its internal pores form a three-dimensional mesh-like interconnected structure. The hexagonal through holes are evenly distributed along the length of the beam, and the axial direction of the through holes forms an angle of 30°-60° with the noise propagation direction. The sound insulation block is fixed to the inner wall of the sound insulation cavity with an elastic adhesive.

[0008] Preferably, the thermal bridge is a hollow structure, with multiple sets of support columns inside arranged in a star-shaped pattern, the included angle between adjacent support columns being 60°-120°, the support columns being hollow tubular structures with a wall thickness of not less than 0.8mm, each set of support columns being filled with a thermal insulation and sound absorption layer composed of glass wool and damping adhesive, and annular sealing grooves being provided at the connection points between the thermal bridge and the beam body at both ends, with silicone rubber sealing rings embedded in the grooves.

[0009] Preferably, the sealing edge is made of EPDM rubber, and the cross-section of the sealing edge has an L+arc lip combination structure.

[0010] Preferably, the two ends of the support column are fixed to the upper and lower inner walls of the sound insulation cavity by welding or injection molding, and shock-absorbing pads are provided at the fixing points.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model uses a sound-insulating block with hexagonal through holes to fill the sound-insulating cavity inside the beam, combined with the zigzag layout of the inclined and alternating hollow support columns, to transform the traditional single and double cavity linear sound wave path into a composite path of multi-directional refraction and multiple reflections, which effectively weakens the penetration of mid-to-high frequency noise. At the same time, the hollow structure of the support columns can be filled with sound-absorbing material to further suppress structural sound transmission, solving the problem that traditional profile cavities directly transmit noise and are prone to deformation after filling.

[0013] 2. This utility model uses a silicone rubber sealing ring embedded in the annular sealing groove at the connection between the thermal bridge and the beam, combined with the double compression seal of the L+arc lip along the edge of the beam, to block noise from seeping in through the connection gap. The support column fixing point is equipped with a shock-absorbing pad to isolate rigid contact and suppress external vibration from being transmitted through the profile, thus making up for the shortcomings of traditional installation gaps lacking systematic sealing and rigid connection leading to noise transmission.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A high-efficiency sound and heat insulation composite aluminum alloy window includes two sets of beams 1, each with a sound insulation cavity 2. Sound insulation blocks 3 are filled within the sound insulation cavities 2. Multiple hexagonal through holes are formed on the outer wall of each sound insulation block 3. The two sets of beams 1 are connected by a heat insulation bridge 5. Connecting grooves 4 and connecting edges 6 are provided on the outer wall of each beam 1. The connecting grooves 4 and connecting edges 6 cooperate with each other and are used to connect the beams 1 to other components. Sliding grooves 7 for installing sliding components are provided on the beams 1. Sealing edges 8 are provided on the edges of the beams 1. Multiple sets of support columns 9 are provided within the sound insulation cavities 2. These support columns 9 are arranged at an angle and alternately, and are hollow inside.

[0020] Furthermore, by setting a sound insulation cavity 2 inside the beam 1 and filling it with a sound insulation block 3 with hexagonal through holes, the traditional single and double cavity linear sound wave path is transformed into a multi-directional refraction path, which weakens the penetration of mid-to-high frequency noise. The inclined and alternating hollow support column 9 replaces the traditional single cavity structure, which increases the number of sound wave reflections through the zigzag layout and provides structural support for the sound insulation cavity 2. This solves the problem of profile deformation caused by filling sound insulation material in large-size windows and avoids the defect of excessive deflection after filling traditional single and double cavities.

[0021] The sound insulation block 3 is integrally formed with porous sound-absorbing material. Its internal pores form a three-dimensional mesh structure. The hexagonal through holes are evenly distributed along the length of the beam 1, and the axial direction of the through holes forms an angle of 30°-60° with the direction of noise propagation. The sound insulation block 3 is fixed to the inner wall of the sound insulation cavity 2 with elastic adhesive.

[0022] Furthermore, the three-dimensional mesh structure and inclined through-hole design enable sound waves to form a diffusion-absorption-damping composite effect within the sound insulation block 3, which is more effective in consuming sound energy compared to traditional straight through-holes. The elastic adhesive connection avoids rigid contact between the sound insulation block 3 and the beam 1, reducing solid-borne sound transmission and solving the noise transmission problem caused by rigid connections in traditional filling materials. At the same time, it adapts to the thermal expansion and contraction deformation of the profile, preventing the filling layer from cracking and leaking sound.

[0023] The thermal bridge 5 is a hollow structure with multiple sets of support columns 9 arranged in a star shape inside. The included angle between adjacent support columns 9 is 60°-120°. The support columns 9 are hollow tubular structures with a wall thickness of not less than 0.8mm. Each set of support columns 9 is filled with a thermal insulation and sound absorption layer composed of glass wool and damping adhesive. Annular sealing grooves are provided at the connection between the thermal bridge 5 and the beam 1 at both ends, and silicone rubber sealing rings are embedded in the grooves.

[0024] Furthermore, the star-shaped support column 9 enhances the structural strength of the thermal bridge 5, avoiding the risk of breakage caused by the lack of internal support in traditional nylon thermal insulation strips; the hollow tubular support column 9 is filled with a composite thermal insulation and sound absorption layer, simultaneously achieving heat conduction blocking and noise absorption, solving the defect of traditional thermal bridges that only insulate heat but not sound; the combination of the annular sealing groove and the silicone rubber sealing ring forms a double seal at the connection between the beam 1 and the thermal bridge 5, blocking the path of noise seeping in from the profile connection part, making up for the lack of systematic sealing in traditional installation gaps.

[0025] The sealing edge 8 is made of EPDM rubber. The cross-section of the sealing edge 8 is an L+arc lip combination structure. The two ends of the support column 9 are fixed to the upper and lower inner walls of the sound insulation cavity 2 by welding or injection molding, and shock-absorbing pads are provided at the fixing points.

[0026] Furthermore, the L+ arc-shaped lip structure creates a multi-compression seal between the seal along the 8-inch edge and the glass or wall surface, which can effectively block high-frequency noise leaks compared to traditional straight rubber strips.

[0027] In this invention, when the device is used, external noise is transmitted to the aluminum alloy window through air conduction via window seams and profile cavities, or through solid conduction via profile vibration and installation nodes, propagating into the room. The sound insulation cavity 2 inside the beam 1 is filled with a sound insulation block 3 with hexagonal through-holes, transforming the traditional single / double-cavity linear sound wave path into a multi-directional refraction path. When sound waves enter the hexagonal through-holes on the outer wall of the sound insulation block 3, multi-directional refraction occurs because the axis of the through-hole forms a 30°-60° angle with the direction of noise propagation, extending the propagation path and consuming sound energy, thus weakening the penetration of mid-to-high frequency noise. The three-dimensional interconnected porous structure inside the sound insulation block 3 allows sound waves to rub against the pore walls within the pores, converting sound energy into heat energy, thereby absorbing mid-to-low frequency noise. The sound insulation block 3 is fixed to the inner wall of the sound insulation cavity 2 with an elastic adhesive, forming a flexible connection to avoid solid-borne sound transmission caused by rigid contact, while also adapting to the thermal expansion and contraction of the profile, preventing cracking and sound leakage in the filling layer.

[0028] Multiple sets of inclined and alternating hollow support columns 9 are arranged in a zigzag pattern to divide the sound insulation cavity 2 into complex cavities. The sound waves are attenuated after being reflected multiple times by the surface of the support columns 9 in the cavity, avoiding the "sound tunnel" effect of traditional straight cavities. The hollow structure inside the support columns 9 can be further filled with sound-absorbing material. The vibration of its tube wall consumes energy through internal friction of the material, suppressing structural sound transmission. At the same time, it provides structural support for the sound insulation cavity 2, solving the problem of profile deformation after filling large-sized window types with sound insulation material.

[0029] The two sets of beams 1 are connected by a thermal bridge 5. The support columns 9 inside the thermal bridge 5 are hollow tubular structures with a wall thickness of not less than 0.8mm. The inside is filled with a heat-insulating and sound-absorbing layer composed of glass wool and damping adhesive. The glass wool absorbs noise, and the damping adhesive consumes vibration energy, thus blocking heat conduction and noise transmission simultaneously. The annular sealing grooves at the connection between the thermal bridge 5 and the beam 1 are inlaid with silicone rubber sealing rings, forming a double barrier of physical sealing and elastic compression, blocking the path of noise infiltration from the connection point.

[0030] The sealing edge 8 of beam 1 is made of EPDM rubber, with an L+arc lip combination structure in cross-section. The vertical L-shaped section fits the edge of the beam, and the free end of the arc lip is elastically squeezed against the glass or wall surface to form two sealing interfaces, effectively blocking high-frequency noise leakage points. The damping pads at the fixed points of the support column 9 at both ends and the upper and lower inner walls of the sound insulation cavity 2 isolate rigid contact, suppress external vibrations from being transmitted to the room through the support structure, and reduce solid-borne sound transmission.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
