Description

Technical Field

[0001] This invention relates to the field of general building technology, and more specifically to a building sound insulation and heat insulation component and its processing method. Background Technology

[0002] People have increasingly stringent requirements for their living and working environments. They not only expect buildings to effectively resist external noise interference and create a quiet indoor atmosphere, but also desire good thermal insulation performance to reduce energy consumption and achieve a comfortable experience of warmth in winter and coolness in summer. Traditional insulation materials, such as rock wool, while possessing certain thermal insulation properties, perform poorly in sound insulation and suffer from inconvenient construction. For example, during installation, the fibers of rock wool are easily dispersed, posing a health hazard to the respiratory system of construction workers. Regarding sound insulation structures, existing building walls mostly use flat panel structures, lacking effective reflection and absorption mechanisms when sound waves propagate within them, resulting in unsatisfactory sound insulation. For instance, ordinary brick-concrete walls have limited ability to block traffic noise and neighborhood noise, failing to meet people's demand for a quiet environment.

[0003] With the continuous development of the construction industry, the demand for efficient, environmentally friendly, and easy-to-install building sound and heat insulation components is becoming increasingly urgent. Developing a new type of building sound and heat insulation component that can effectively solve the above problems, comprehensively improve sound and heat insulation performance, and simplify the construction and installation process has important practical significance and broad market prospects. Summary of the Invention

[0004] This invention provides a building sound insulation and heat insulation component and its processing method, which can reduce noise, insulate heat and facilitate construction.

[0005] The above objectives are achieved through the following technical solutions:

[0006] A building sound and heat insulation component includes a shell, the shell having a cavity, a corrugated surface inside the cavity, and a noise reduction and heat insulation material that is adhered to the corrugated surface inside the cavity.

[0007] It also includes corrugated sheets, the back of the corrugated sheets, or corrugated sheets with corrugated surfaces on both the back and front.

[0008] The edges of the corrugated sheet are provided with butt joints;

[0009] The housing includes two side support parts, each side support part is provided with at least one first mating groove, and the two ends of the mating part are respectively inserted into the first mating grooves on the two side support parts.

[0010] The mating part is integrally formed with the corrugated plate, or the mating part is fixedly attached to the corrugated plate.

[0011] It also includes a panel, and the side support has at least one second mating groove for inserting the panel.

[0012] The number of second mating grooves on each side support is two, and the number of panels is two. The two panels and the two side supports form a shell. The corrugated plate is located inside the shell. When there is one corrugated plate, the noise reduction and heat insulation material filled between the corrugated plate and the outer panel is foam, and the noise reduction and heat insulation material filled between the corrugated plate and the inner panel is aerogel. When there are not less than two corrugated plates, the noise reduction and heat insulation material filled between at least two adjacent corrugated plates is aerogel, and the noise reduction and heat insulation material filled in other positions inside the shell is foam and / or aerogel.

[0013] A pressing component is fixed to the lower end of the upper panel. Both ends of the pressing component have bevels, which are on a virtual V-shape. A buffer structure is attached to the pressing component. When the pressing component moves downward, the compression buffer structure moves laterally.

[0014] The buffer structure includes a contact element, one end of a guide element fixed to the contact element, and a resistance plate fixed to the other end of the guide element. The guide element is used to pass through the corrugated sidewall of the corrugated plate, that is, the wall between the crest and trough of the corrugated plate. The contact element is used to make surface contact with the inclined surface of the pressing element. The resistance plate is located in the foam area and is parallel to the contact element.

[0015] The resistance plate is attached to the corrugated sidewall of the corrugated plate near the contact element.

[0016] A method for processing building sound and heat insulation components includes the following steps:

[0017] Step 1: Build the outer shell;

[0018] Step 2: Form a corrugated surface inside the outer shell;

[0019] Step 3: Fill the shell with noise-reducing and heat-insulating material and attach it to the corrugated surface.

[0020] The beneficial effects of the building sound insulation and heat insulation component and its processing method of the present invention are as follows:

[0021] The corrugated sidewalls disperse external forces through a 30°-45° inclination angle, enhancing the bending resistance of the component despite its relatively thin thickness. The aerogel within the corrugated cavity, combined with the sidewalls, forms a labyrinthine heat flow path, increasing thermal resistance and reducing the heat transfer coefficient compared to traditional flat plate structures. The inclination angle of the sidewalls further extends the heat conduction path, inhibiting heat transfer even more. Sound waves are reflected multiple times between the corrugated sidewalls, and together with damping sheets and filling materials, absorb energy, thus reducing noise. Attached Figure Description

[0033] A building sound and heat insulation component includes a shell, the shell having a cavity, and a corrugated surface provided inside the cavity. The corrugated surface may be part of the shell or may be inside the shell.

[0034] Preferred, for example Figure 1 The corrugated board 1 forms a corrugated surface, with its back inner surface, or its front and back sides having a wavy structure. When the front and back sides have a wavy structure, the board as a whole presents a double-sided continuous undulating corrugated shape, with the crests and troughs corresponding one-to-one on both sides of the board.

[0035] The cavity is filled with a porous filler material, such as expanding foam and / or aerogel, attached to the corrugated surface. The porous filler material utilizes the "bypass effect" caused by the bending of the corrugated structure to increase thermal resistance and reflect sound, thereby improving sound energy attenuation.

[0036] Example 1, combined with Figure 2 and 3It facilitates assembly, configuration adjustments, and ease of application for painting work.

[0037] A mating portion 1a is fixed or formed at the edge and trough of the corrugated plate 1. The outer shell includes a side support portion 2, on which at least one first mating groove 2a is provided. The mating portion 1a is inserted into the first mating groove 2a to achieve splicing. Processing method: In Figure 3 In the middle, the left and right sides of the mating part 1a are provided with first mating grooves 2a. This is to increase the splicing amount of corrugated plates 1 and make the corrugated plates 1 arranged laterally. The number of first mating grooves 2a on one side of the mating part 1a determines the number of corrugated plates 1 that can be inserted.

[0038] The side support 2 has second mating grooves 2b on its upper and lower sides for inserting the panel 3. The panel 3 is used for applying putty to facilitate paint application and the formation of a painted surface. Thus, the two side support 2 (left and right) and the two panels 3 (top and bottom) can surround each other to form a shell. The cavity inside the shell is for placing the corrugated plate 1. Alternatively, one of the panels 3 can be replaced with a corrugated plate 1, but the corrugated plate 1 requires more putty. Similarly, to increase the amount of panel 3 that can be joined, second mating grooves 2b are provided on both the left and right sides of the mating part 1a to achieve lateral extension.

[0039] Considering cost-effectiveness, the preferred quantity of corrugated sheet 1 is two, i.e. Figure 1 As shown in the diagram, two corrugated plates 1 are equidistantly spaced to form a corrugated cavity. Aerogel is filled into the corrugated cavity, while expanding foam is filled between any one corrugated plate 1 and the adjacent panel 3.

[0040] Among them, right-angle fixing pieces can be installed between the side support part 2 and the panel 3, and between the corrugated plate 1 and the mating part 1a for reinforcement.

[0041] Example 2, combined with Figure 4 For the outer panel 3, if there is a risk of collision, the width of the second mating groove 2b adjacent to the outer panel 3 can be increased, i.e., the outer panel 3... Figure 3 The upper panel 3 has room to recoil after being impacted, and the expanding foam acts as a buffer during this recoil. Injection holes can be machined on the outer panel 3 to facilitate secondary injection and backfilling after the original expanding foam has been compressed.

[0042] Furthermore, a pressing component 3a is fixed to the lower end of the upper panel 3. The pressing component 3a has inclined surfaces at both ends, and the two inclined surfaces are on a virtual V-shape. When the pressing component 3a moves downward, it compresses the buffer structure used to increase the lateral force-bearing area, so as to distribute the downward force to the left and right sides, and the foam adhesive is used to buffer the component forces on the left and right sides.

[0043] For example, combined with Figure 5Located on the left-side slope, a contact element 4 is in surface contact with the corrugated plate 1. A guide element 4a is fixed to the left end of the contact element 4. The guide element 4a passes through a bend in the corrugated plate 1, placing the left end of the guide element 4a in a relatively wide area. In this area, obstacles to the left of the guide element 4a are at a certain distance from the guide element 4a. A resistance plate 5, which increases the area, is fixed to the left end of the guide element 4a. The resistance plate 5 is inclined and its surface contacts the slope between a crest and a trough of the corrugated plate 1. When the resistance plate 5 moves to the left, in addition to dissipating the left-side force through the expanding foam, the slope of the resistance plate 5 also generates an upward force, thereby increasing the force dissipation direction, which is ultimately buffered by the expanding foam.

[0044] Figure 1 and 4 The product is typically laid flat in the center. When erected, it serves as a sound and heat insulation layer. The stacking process, where the layers are stacked upwards, can be achieved through reinforcement. Figures 7 to 10 The reinforcement includes a sealing plate 6, and corrugated connectors 7 are fixed to both ends of the sealing plate 6. The connectors 7 are used to insert between the two corrugated plates 1 to provide support and connection. Figure 10 The corrugated plate 1 at the top is removed, so that the connector 7 between the two corrugated plates 1 can be seen.

[0045] Depending on actual needs, the positions of the supply panel 3 and the corrugated plate 1 can be changed, and the specifications of the first mating groove 2a and the second mating groove 2b can be the same.
