Description

Technical Field

[0001] The utility model belongs to the field of building thermal insulation, and in particular relates to a cast-in-place concrete thermal insulation structure. Background Art

[0002] Wall insulation is a key focus for building energy conservation. Heat loss from the building envelope accounts for 70% to 80%, while air loss through gaps between doors and windows contributes 20% to 30%. Exterior walls account for the largest proportion of the building envelope and are the primary source of energy loss. Exterior wall insulation is a commonly used insulation structure, and formwork-free systems such as integrated insulation structures are a popular choice in the insulation field.

[0003] Furthermore, the quality of the indoor acoustic environment is a crucial factor in evaluating a good building environment. Existing technologies typically apply sound-absorbing paint or install sound-absorbing panels on the exterior insulation layer of a building's exterior walls, increasing the number of construction steps and the time required for high-altitude work. Furthermore, building noise propagates in two ways: solid-borne sound, which typically forms plane waves on the surface of the building structure and then refracts into the interior, generating noise; and airborne sound, which propagates linearly through the air and refracts through the building structure, generating noise. Whether using sound-absorbing paint or panels, these methods are not ideal for reducing solid-borne noise, resulting in a decrease in the quality of the indoor acoustic environment. Utility Model Content

[0004] The utility model provides a cast-in-situ concrete insulation structure to solve the problems of poor noise reduction effect of existing building exterior wall insulation structures and low indoor sound environment quality.

[0005] The technical solution adopted by this utility model is:

[0006] A cast-in-place concrete insulation structure is arranged on the outside of a cast-in-place concrete wall, comprising an insulation board, wherein the insulation board has a fixed side facing the cast-in-place concrete wall and a protective side facing away from the cast-in-place concrete wall, the protective side being provided with a base and a raised portion raised outward relative to the base, the raised portion being curved and extended on the surface of the fixed side to enclose a curved and extended noise reduction channel.

[0007] The cast-in-situ concrete insulation structure of the present invention also has the following additional technical features:

[0008] The raised portion has a starting point end, and the raised portion is a multi-circle structure, which rotates away from the starting point in each circle, and the noise reduction channel is formed between two adjacent circles of the raised portion.

[0009] The raised portion is a strip-shaped structure extending along the surface of the protection side, and the raised portion is bent at least once on the surface of the protection side to form a curved and extended noise reduction channel.

[0010] The raised portion includes a plurality of raised structures, and the plurality of raised structures are arranged along a first path. The first path is bent at least once so that the raised portion forms a curved and extended noise reduction channel.

[0011] The protruding structure has a fixed end connected to the base,

[0012] In the first path, the fixed ends of adjacent protrusion structures abut against each other, or,

[0013] In the first path, there is a gap between the fixed ends of the adjacent protruding structures, and the maximum width of the gap is A. The width of the noise reduction channel is B, and A is smaller than B.

[0014] The protrusion has a fixed end connected to the base, and the protection side is further provided with an isolation groove recessed inward relative to the base, and the isolation groove is located outside the fixed end.

[0015] The insulation board includes an inner adhesive layer located on the fixed side, an outer protective layer located on the protective side, and an insulation layer located between the inner adhesive layer and the outer protective layer. The insulation layer is provided with a raised structure on the side facing the protective side, and the outer protective layer protrudes outward corresponding to the raised structure to form the raised portion on the surface of the outer protective layer.

[0016] The outer protective layer is provided with a noise reduction hole on the raised portion. The noise reduction hole passes through the outer protective layer, the thermal insulation layer and the inner adhesive layer to form a vibration reduction cavity. The vibration reduction cavity bends and extends in the thermal insulation layer.

[0017] The raised portion includes a supporting section close to the base and a raised section away from the base. The cross-sectional size of the raised section gradually increases toward the base, and the surface of the raised section has an inwardly concave transition arc surface.

[0018] The cast-in-place concrete insulation structure also includes a fixing piece, and the insulation board is fixed to the cast-in-place concrete wall through the fixing piece. The fixing piece is perpendicular to the wall surface. The fixing piece includes a fixing portion located in the cast-in-place concrete wall, and the fixing portion is provided with a fixing protrusion protruding along the radial direction of the fixing piece and extending obliquely toward the insulation board.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0020] 1. In the present invention, when noise propagates into the room, most of the energy forms surface waves along the free surface and then enters the room through refraction to form noise. The protection side is provided with a base and a raised portion that protrudes outward relative to the base. When the surface wave encounters the raised portion with a changed shape during propagation at the base, a new vibration source point is formed at the edge of the base, forming a diffraction wave relative to the raised portion, and most of the energy is concentrated at the base. The raised portion blocks the propagation of noise and reduces the noise energy that is directly propagated into the room. The raised portion extends in a zigzag manner on the surface of the fixed side, forming the curved noise reduction channel. The raised portion guides the surface wave to propagate along the noise reduction channel, thereby increasing the propagation path of the noise in the noise reduction channel. As the propagation distance increases, the noise energy is greatly attenuated, reducing the impact of noise on residents.

[0021] 2. As a preferred embodiment of the present invention, the raised portion has a starting point, and the raised portion is a convoluted multi-turn structure, which rotates away from the starting point one by one, and the noise reduction channel is formed between two adjacent circles of the raised portion. During the propagation of noise in the noise reduction channel, the raised portion of the convoluted multi-turn structure blocks the noise in multiple directions, allowing more noise energy to propagate along the convoluted noise reduction channel, reducing the impact of noise propagating horizontally along the wall on residents on the same floor, and reducing the impact of noise propagating vertically along the wall on residents on adjacent floors. During the propagation of noise in the noise reduction channel of the convoluted multi-turn structure, the noise energy gradually decreases. After part of the energy propagates to the starting point, the noise is reflected at the starting point, and the reflected wave interferes with the incident wave, reducing the noise energy and improving the absorption of noise.

[0022] 3. As a preferred embodiment of the present invention, the raised portion has a fixed end connected to the base, and the protective side is further provided with an isolation groove that is recessed inward relative to the base, and the isolation groove is located on the outside of the fixed end. During the process of noise propagating on the outer surface of the protective side, the isolation groove can reduce the noise energy that is transmitted through the raised portion, thereby reducing the noise energy that is transmitted into the room and reducing the impact of noise on residents. The isolation groove improves the guiding effect on the direction of noise propagation, allowing a larger proportion of noise energy to propagate along the noise reduction channel, thereby improving the noise reduction effect of the noise reduction channel on noise.

[0023] 4. As a preferred embodiment of the present invention, the insulation board includes an inner adhesive layer located on the fixed side, an outer protective layer located on the protective side, and an insulation layer located between the inner adhesive layer and the outer protective layer. The insulation layer is provided with a raised structure on the side facing the protective side, and the outer protective layer protrudes outwardly corresponding to the raised structure to form the raised portion on the surface of the outer protective layer. The outer protective layer and the inner adhesive layer form a support for the insulation layer to avoid structural damage to the insulation layer during the pouring of concrete, or concrete seeping into the insulation layer and adversely affecting the insulation effect of the insulation layer. The outer protective layer protrudes outwardly corresponding to the raised structure to form a raised portion on the surface of the outer protective layer. When air noise is incident on the insulation board, the raised portion realizes a continuous transition from the characteristic impedance of air to the characteristic impedance of the insulation layer, thereby allowing the noise to enter the insulation layer more effectively and the noise to be effectively attenuated within the insulation layer.

[0024] 5. As a preferred embodiment of the present invention, the outer protective layer is provided with a noise reduction hole in the raised portion, and the noise reduction hole passes through the outer protective layer, the thermal insulation layer and the inner adhesive layer to form a vibration reduction cavity, and the vibration reduction cavity bends and extends within the thermal insulation layer. The noise reduction hole is provided on the raised portion, which further reduces the energy of surface waves propagating through the outer surface of the raised portion, improves the ability to guide noise, and guides the noise to propagate along the noise reduction channel. For incident air waves in the noise, the noise reduction hole reduces the resonance generated by the outer protective layer, and the noise reduction hole changes the propagation path and direction of the noise. The noise is reflected, scattered and absorbed in the noise reduction hole, reducing the energy of the noise. The vibration reduction cavity bends and extends within the thermal insulation layer, which increases the propagation length of the noise in the vibration reduction cavity and improves the noise reduction effect of the vibration reduction cavity on noise.

DETAILED DESCRIPTION

[0035] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0037] In addition, in the description of the present invention, it should be understood that the terms "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0038] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0039] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "implementation method", "embodiment", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0040] like Figures 1 to 4 As shown, a cast-in-place concrete insulation structure is arranged outside the cast-in-place concrete wall 1, including an insulation board 2, wherein the insulation board 2 has a fixed side 21 facing the cast-in-place concrete wall 1, and a protective side 22 facing away from the cast-in-place concrete wall 1, the protective side 22 is provided with a base 221 and a raised portion 222 raised outward relative to the base 221, and the raised portion 222 is bent and extended on the surface of the fixed side 21 to enclose a curved and extended noise reduction channel 23.

[0041] It should be noted that the cast-in-place concrete insulation structure described in the present invention is suitable for cast-in-place concrete walls with built-in outer formwork. That is, the insulation board 2 is used to build the concrete outer formwork, and the cast-in-place concrete wall 1 is cast inside the concrete outer formwork. The insulation board 2 and the cast-in-place concrete wall 1 are firmly connected to form the cast-in-place concrete insulation structure. The cast-in-place concrete insulation structure can also be used with common adhesive insulation boards, which are attached to the outer surface of an existing wall. This is not a limitation of the present invention.

[0042] The cast-in-place concrete insulation structure does not require the removal of the concrete outer formwork and the installation of the insulation structure on the wall surface, which can simplify the insulation structure construction steps and improve construction efficiency. In addition, the cast-in-place concrete wall 1 is directly cast on the fixed side 21, and the fixed side 21 is more tightly attached to the cast-in-place concrete wall 1, reducing problems such as warping of the cast-in-place concrete insulation structure.

[0043] In addition, existing noise reduction structures generally eliminate the incident air waves in the noise, thereby reducing the disturbance caused by the noise to the residents. However, in the process of noise propagating into the room, most of the energy propagates along the free surface as surface waves, and then enters the room through refraction to form noise. The existing noise reduction technology has no obvious noise reduction effect on surface waves propagating along the solid interface. The protective side 22 is provided with a base 221 and a protrusion 222 protruding outward relative to the base 221. When the surface wave encounters the protrusion 222 with a changed shape during propagation in the base 221, a new vibration source point will be formed at the edge of the base 221, forming a diffraction wave relative to the protrusion 222, and most of the energy is concentrated on the base 221. The protrusion 222 forms a barrier to the propagation of noise, increases the path length of the noise transmitted into the room, and reduces the noise energy transmitted into the room. The raised portion 222 bends and extends on the surface of the fixed side 21 to form the curved and extended noise reduction channel 23, which increases the propagation path of the noise in the noise reduction channel 23. As the propagation distance increases, the noise energy is greatly attenuated, reducing the impact of the noise on residents.

[0044] In addition, existing noise reduction structures generally achieve noise reduction by coating the outer surface of the insulation board with a sound-absorbing coating or installing a sound-absorbing board on the outer surface of the insulation board. In the present invention, the raised portion 222 formed by the raised protection side 22 realizes the design of a noise reduction structure through the insulation board 2, so that the insulation board 2 has both heat insulation and noise reduction functions, reducing production costs and improving construction efficiency.

[0045] As a preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the raised portion 222 has a starting point 2221. The raised portion 222 has a convoluted multi-turn structure, spiraling away from the starting point 2221. The noise reduction channel 23 is formed between two adjacent turns of the raised portion 222. As noise propagates within the noise reduction channel 23, the convoluted multi-turn raised portion 222 blocks the noise in multiple directions, allowing more noise energy to propagate along the convoluted noise reduction channel 23. This reduces the impact of noise propagating horizontally along the wall on residents on the same floor, and reduces the impact of noise propagating vertically along the wall on residents on adjacent floors. As noise propagates along the convoluted multi-turn noise reduction channel 23, its energy gradually decreases. After some of the energy reaches the starting point 2221, it is reflected there. The reflected wave interferes with the incident wave, reducing the noise energy and improving noise absorption.

[0046] Preferably, the raised portion 222 extends to form a planar spiral or meandering shape. The structural design of the raised portion 222 can improve the aesthetics of the outer surface of the protective side 22, thereby improving the overall appearance design of the building.

[0047] The present invention does not limit the structural formation method of the curved extension of the protrusion 222, and any one of the following implementation methods can be adopted.

[0048] Implementation method 1: Figure 3 、 Figure 4 and Figure 6 As shown, the raised portion 222 is a strip-like structure extending along the surface of the protective side 22. The raised portion 222 bends at least once on the surface of the protective side 22 to form a curved, extended noise reduction channel 23. The strip-like raised portion 222 enhances the structural strength of the protective side 22 and improves the protection of the insulation board 2. The raised portion 222 bends and extends to form the curved, extended noise reduction channel 23, thereby increasing the length of the noise propagation path within the noise reduction channel 23.

[0049] Implementation method 2: Figure 5 As shown, the raised portion 222 includes a plurality of raised structures, which are arranged along a first path. The first path is curved at least once so that the raised portions 222 form a curved and extended noise reduction channel 23. The plurality of raised structures are arranged to form the raised portion 222. The first path is the extension direction of the raised portion 222. The first path is curved so that the raised portions 222 form the curved and extended noise reduction channel 23, thereby increasing the propagation path length of the noise within the noise reduction channel 23. The raised structure has a fixed end 2222 connected to the base 221 and a raised end away from the base 221. The raised structure is discontinuous at the raised end, thereby reducing the energy of noise transmitted along the raised end.

[0050] As an example of this embodiment, in the first path, the fixed ends 2222 of adjacent raised structures abut against each other, which can enhance the noise blocking effect of the raised portions 222, reduce noise diffraction around the raised structures, and reduce the amount of noise energy directly transmitted into the room. More noise energy is concentrated within the noise reduction channel 23, thereby enhancing the vibration and noise reduction effect.

[0051] As another example under this embodiment, Figure 5As shown, in the first path, there is a gap between the fixed ends 2222 of the adjacent raised structures, and the maximum gap is A. The width of the noise reduction channel 23 is B, and A is smaller than B. The layout of the raised structure is more flexible, and the appearance of the protection side 22 can be improved by optimizing the layout of the raised structure. The gap between the fixed ends 2222 is smaller than the width of the noise reduction channel 23. The noise is blocked by the raised structure, and diffraction is generated relative to the raised structure. More energy is transmitted on the larger planar structure. The size A of the gap is smaller than the width B of the noise reduction channel 23. More energy is transmitted within the noise reduction channel 23, which is more conducive to absorbing the noise.

[0052] like Figure 1 and Figure 2 As shown, the raised portion 222 has a fixed end 2222 connected to the base 221. The protective side 22 is also provided with an isolation groove 223 that is recessed inward relative to the base 221 and is located outside the fixed end 2222. As noise propagates along the outer surface of the protective side 22, the isolation groove 223 can reduce the noise energy that is transmitted through the raised portion 222, thereby reducing the noise energy that propagates into the room and reducing the impact of noise on residents. The isolation groove 223 enhances the guidance of the noise propagation direction, allowing a greater proportion of the noise energy to propagate along the noise reduction channel 23, thereby improving the noise reduction effect of the noise reduction channel 23.

[0053] As a preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the insulation board 2 includes an inner adhesive layer 24 located on the fixed side 21, an outer protective layer 25 located on the protective side 22, and an insulation layer 26 located between the inner adhesive layer 24 and the outer protective layer 25. The insulation layer 26 is provided with a raised structure 261 on the side facing the protective side 22. The outer protective layer 25 protrudes outwardly corresponding to the raised structure 261 to form the raised portion 222 on the surface of the outer protective layer 25. The outer protective layer 25 and the inner adhesive layer 24 provide support for the insulation layer 26, preventing structural damage to the insulation layer 26 during concrete pouring, or concrete from penetrating the insulation layer 26 and adversely affecting its insulation effect.

[0054] Preferably, the outer protective layer 25 is made of a metal plate structure, for example, it is made of aluminum plate, aluminum-plastic plate, stainless steel plate, copper plate, color steel plate and other plates. The thermal insulation layer 26 is made of foamed polyurethane plate, phenolic plate, polystyrene plate and other plates. The thermal insulation layer 26 has lower hardness and greater porosity than the outer protective layer 25, and has a stronger noise reduction effect. The outer protective layer 25 protrudes outward corresponding to the raised structure 261 to form a raised portion 222 on the surface of the outer protective layer 25. When the air noise is incident on the thermal insulation board 2, the raised portion 222 realizes a continuous transition from the characteristic impedance of the air to the characteristic impedance of the thermal insulation layer 26, so that the noise enters the thermal insulation layer 26 more effectively, and the noise is effectively attenuated in the thermal insulation layer 26.

[0055] Preferably, Figure 6 As shown, the outer protective layer 25 is provided with noise reduction holes 251 on the raised portion 222. The noise reduction holes 251 penetrate the outer protective layer 25, the thermal insulation layer 26, and the inner adhesive layer to form a vibration reduction cavity, which bends and extends within the thermal insulation layer 26. Surface waves generally propagate along the outer protective layer 25. The provision of the noise reduction holes 251 on the raised portion 222 reduces the integrity of the outer surface of the raised portion 222, further blocking the propagation of surface waves and reducing the energy of surface waves transmitted through the outer surface of the raised portion 222. This improves the ability to guide noise, directing it along the noise reduction channel 23.

[0056] The noise reduction holes 251 reduce the resonance of the outer protective layer 25 in the incident air noise. They also alter the propagation path and direction of the noise, causing it to be reflected, scattered, and absorbed within the holes 251, reducing the noise energy. The vibration-damping cavity bends and extends within the insulation layer 26, increasing the propagation length of the noise within the cavity. This provides a longer propagation path within the insulation layer 26 and further enhances the noise reduction effect of the insulation layer 26.

[0057] In addition, the inner adhesive layer 24, the thermal insulation layer 26, and the outer protective layer 25 are made of different materials and have different thermal expansion and contraction coefficients. At different temperatures, the inner adhesive layer 24, the thermal insulation layer 26, and the outer protective layer 25 may warp and detach. The vibration damping cavity passes through the inner adhesive layer 24, the thermal insulation layer 26, and the outer protective layer 25 to maintain the temperature balance between the inner adhesive layer 24, the thermal insulation layer 26, and the outer protective layer 25, avoid thermal bridge problems, and reduce warping and detachment problems.

[0058] As a preferred embodiment of the present invention, Figure 5 and Figure 6As shown, the raised portion 222 includes a support segment 2223 proximal to the base 221 and a raised segment 2224 distal to the base 221. The cross-sectional dimensions of the raised segment 2224 gradually increase toward the base 221, and the surface of the raised segment 2224 has an inwardly concave transition arc 2225. The cross-sectional dimensions of the raised segment 2224 gradually increase toward the base 221, so that the characteristic impedance of the raised segment 2224 gradually transitions from the characteristic impedance of air to the characteristic impedance of the insulation board 2, making incident airborne noise more easily absorbed by the insulation board 2. The inwardly concave transition arc 2225 on the surface of the raised segment 2224 reflects airborne noise, reducing the incident noise energy and thereby improving the noise reduction effect.

[0059] The present invention does not limit the thickness of the base 221. In one embodiment, the thickness of the base 221 is 50 mm, which is about 1 / 4 of the noise wavelength, can achieve a good noise reduction effect, and reduce the thickness of the insulation board 2, thereby reducing operating costs.

[0060] As a preferred embodiment of the present invention, Figure 1 As shown, the cast-in-place concrete insulation structure further includes a fixing member 3, through which the insulation board 2 is fixed to the cast-in-place concrete wall 1. The fixing member 3 is perpendicular to the wall surface and includes a fixing portion 31 located within the cast-in-place concrete wall 1. The fixing portion 31 is provided with a fixing protrusion 311 that protrudes in the radial direction of the fixing member 3 and extends obliquely toward the insulation board 2. The fixing member 3 is fixed to the insulation board 2, and then concrete is poured on the fixing side 21 to form the cast-in-place concrete wall 1. In this way, the insulation board 2 and the cast-in-place concrete wall 1 are cast as a whole, thereby improving the fixing stability of the insulation board 2 and the cast-in-place concrete wall 1. The fixing portion 31 is located inside the cast-in-place concrete wall 1. When the insulation board 2 generates a force to separate from the cast-in-place concrete wall 1, the cast-in-place concrete wall 1 forms a blocking force on the fixing protrusion 311 toward the inner side of the cast-in-place concrete wall 1, thereby preventing the fixing portion 31 from falling out from the inside of the cast-in-place concrete wall 1. The fixing member 3 improves the fixing stability between the insulation board 2 and the cast-in-place concrete wall 1.
