Description

Technical Field

[0001] This invention relates to a rain-absorbing structure suitable for riverside buildings, and also to buildings with such a rain-absorbing structure on their roofs, belonging to the field of urban noise control and environmental protection technology. Background Technology

[0002] Currently, environmental noise control mainly employs sound barriers to physically isolate and absorb sound. For example, Chinese patent document CN118880773A discloses an ecological sound barrier device and a green isolation device for municipal roads, including a base and a sound barrier body. The surface of the base has slots for inserting the sound barrier body, and the base has grooves near the two side edges. Support plates are rotatably connected to both sides of the sound barrier body. Planting components are connected to the surfaces of the two sets of support plates away from the sound barrier body. The planting components include planting containers with planting cavities that can hold soil for planting plants. Chinese patent document CN112982205A discloses an all-aluminum soundproof decorative wall that is easy to adjust and install, including soundproof panels and adjustable connectors connecting the soundproof panels. A soundproof foam layer is provided in the gap between two adjacent soundproof panels. The soundproof panels are all-aluminum panels, including an outer aluminum panel, an inner aluminum panel, and a foam aluminum panel placed between them. Several soundproof channels are provided on the inner and outer sides of the foam aluminum panel. Meanwhile, noise control in buildings primarily involves sound absorption and insulation, achieved by installing sound insulation layers on walls or roofs. For example, Chinese patent document CN111236544A discloses a sound-insulating metal roof and its installation method. The sound-insulating metal roof includes a base plate, a sound insulation layer, and a panel. The sound insulation layer is located between the base plate and the panel and has sound-absorbing holes for absorbing noise. Chinese patent document CN114961091A discloses a novel trapezoidal metamaterial polyurethane sandwich concrete sandwich wall panel, including an outer wall panel and an inner wall panel. A sound insulation component is installed between the outer wall panel and the inner wall panel. The sound insulation component is connected to the outer wall panel and the inner wall panel on both sides, respectively, and isolates the sound transmitted from the outer wall panel and the inner wall panel, forming a single soundproof wall. These existing technologies each have their own characteristics and are suitable for their respective applications, but they also have their own limitations. For example, light steel structure buildings or other similar buildings are often set up around urban waterways and other garden landscapes as service or rest areas and equipment rooms. The roofs are mostly made of lightweight panels such as color steel sandwich panels. When it rains, rainwater dripping on the roof will produce a lot of noise (rain noise), especially at night or when the rainfall is heavy. Rain noise has a greater impact on the surrounding residents. Setting up sound barriers is not only costly, but also seriously affects the aesthetics of the environment. Summary of the Invention

[0003] The purpose of this invention is to provide a rain-absorbing structure and corresponding building suitable for riverside buildings, so as to reduce rain noise.

[0004] The technical solution of the present invention is: a rain-absorbing and sound-absorbing structure adapted to riverside buildings, which is plate-shaped, with a base plate and a honeycomb panel on the top of the base plate.

[0005] Preferably, the honeycomb panel is made of aluminum and has a polymer impregnation surface layer (a polymer surface layer formed by an impregnation process, or a coating layer).

[0006] Preferably, the adhesive used to form the impregnated surface layer is a water-soluble phenolic resin, an epoxy-modified phenolic resin, or an epoxy adhesive.

[0007] Preferably, the honeycomb panel is a phenolic honeycomb panel.

[0008] Preferably, the pore size (inscribed circle diameter) of the honeycomb panel is 4-6 mm, and the thickness is 10-15 mm, to better accommodate the noise reduction of moderate to heavy raindrops. If necessary, other specifications and dimensions can also be used, and optimized specifications can be obtained through experiments.

[0009] Preferably, a gap is left between the honeycomb panel and the substrate.

[0010] Preferably, the honeycomb panel is fixedly connected to the substrate by a panel support structure.

[0011] Preferably, the panel support structure may be a grating structure (e.g., a rigid plastic grating).

[0012] Furthermore, the aperture of the grille can be significantly larger than that of the honeycomb panel, as long as it can provide stable support and fixation for the honeycomb panel to avoid obstructing the water flow.

[0013] Preferably, the top surface of the substrate (the side surface of the honeycomb panel, or the upper surface) is corrugated, or the bottom surface of the panel support structure is corrugated or grooved, so that water on the substrate surface can flow through the gaps formed by these corrugations or grooves.

[0014] If necessary, several support pads can be placed between the panel support structure and the substrate to form a gap between the panel support structure and the substrate.

[0015] Preferably, a rigid wire mesh (e.g., rigid nylon wire mesh or rigid PC / PS wire mesh) is laid on the top of the honeycomb panel.

[0016] Furthermore, the mesh size of rigid wire mesh can be significantly smaller than the cell diameter of honeycomb panels.

[0017] Preferably, the substrate has a heat insulation / insulation layer.

[0018] The building has a pitched roof or near-pitched roof, and the roof panels adopt any of the rain-absorbing and sound-absorbing structures disclosed in this invention suitable for riverside buildings.

[0019] Preferably, the lower edge of the roof is provided with a horizontally extending water collection trough, into which water flowing from between the honeycomb panel and the substrate enters the water collection trough.

[0020] Preferably, the outlet of the water collection trough is connected to a rainwater pipe or is equipped with a rainwater chain.

[0021] The beneficial effects of this invention are as follows: The use of a honeycomb panel significantly reduces the instantaneous impact of raindrops on the panel, prolonging the impact time and thus significantly reducing rain noise; the honeycomb panel is encapsulated with a high-polymer organic material layer, which not only improves the overall integrity of the honeycomb structure and ensures its strength, but also further reduces rain noise; the gaps between the panel and the main board allow rainwater that passes through the honeycomb structure to flow downwards along the substrate surface after entering the main board, preventing accumulation within the honeycomb structure; and the honeycomb structure's pore size is much larger than that of sound-absorbing felt or sound-absorbing sponge. The regular shape of the holes and their smooth walls make them easy to clean (e.g., by rinsing with water). Rainwater effectively washes away dust and grime from the honeycomb structure surface, preventing clogging. Unlike flexible porous materials such as sound insulation felt, which absorb water and dust, resulting in a significant increase in weight, this design enhances safety. Furthermore, the presence of mesh on the honeycomb panel not only breaks up larger raindrops and reduces noise but also prevents relatively large particles from entering the honeycomb structure, thus avoiding clogging.

[0022] The rain-absorbing and sound-absorbing structural panel of the present invention can be industrially manufactured like existing lightweight roofing panels. Not only is the panel lightweight and easy to assemble, but it can also effectively reduce rain noise, making it suitable for riverside buildings and other similar prefabricated structural buildings. Attached Figure Description

[0023] Figure 1 This is a schematic diagram of the rain-absorbing structure involved in the present invention.

[0024] The markings in the diagram are: 1. Honeycomb panel; 2. Rigid wire mesh; 3. Substrate; 4. Panel support structure; 5. Gap. Detailed Implementation

[0025] See Figure 1This rain-absorbing and sound-absorbing structure is a building panel that can be manufactured in a factory. It is mainly used as a roof panel to form the roof surface. Its main part can be called the substrate 3. The substrate bears the main load of the panel and serves as the installation base for the honeycomb panel 1. The substrate can adopt any suitable existing technology, such as existing building panels or the main part of existing building panels, and has corresponding strength and other properties according to specific usage requirements.

[0026] The honeycomb panel 1 is a honeycomb structured board material, fixedly installed on the substrate, with a gap 5 between it and the substrate. This gap forms a water flow channel, allowing rainwater to flow downwards from the holes in the honeycomb panel, fall onto the substrate surface, and then flow downwards along the substrate surface. The spacing between the honeycomb panel and the substrate is set according to actual needs, ensuring that rainwater can pass through the gap in most cases. The honeycomb panel can adopt any suitable existing technology, such as the honeycomb core material (commonly known as honeycomb core) in existing composite honeycomb panels with skins on both sides, or commercially available honeycomb structured honeycomb boards.

[0027] Honeycomb panels can be made of any suitable material, taking into account factors such as weight, strength, and wall thickness. For example, under the current technological background, aluminum honeycomb panels are the most suitable material for honeycomb panels. To enhance sound absorption and ensure strength / stability, a dipping process (including drying and other supporting processes, when appropriate) is preferred to form a surface coating layer (which can be called the surface layer) of a certain thickness on the surface of the aluminum honeycomb panel. The surface coating layer (the adhesive used for dipping) can be made of polymer materials, such as water-soluble phenolic resin, epoxy-modified phenolic resin, or epoxy adhesive.

[0028] When appropriate, honeycomb panels can also be made of phenolic honeycomb panels or other polymer materials.

[0029] The specifications and dimensions of the honeycomb panel (mainly the aperture and thickness) are determined based on actual needs. If necessary, optimized specifications can be obtained through experiments. Considering factors such as the characteristics of raindrops in moderate and heavy rain and cost, the aperture (inscribed circle diameter) of the honeycomb panel is usually selected as 4-6mm, and the thickness (honeycomb thickness) is usually selected as 10-15mm to better adapt to the sound absorption of raindrops in moderate and heavy rain.

[0030] A panel support structure 4 is provided between the honeycomb panel and the substrate to fix the honeycomb panel to the panel support structure. The panel support structure provides the required strength and facilitates installation on the substrate. The panel support structure is then fixedly installed on the substrate, thereby achieving a fixed connection between the honeycomb panel and the substrate and supporting the gap between the honeycomb panel and the substrate.

[0031] The panel support structure can adopt a grid structure (e.g., rigid plastic grid), whose grid aperture can be significantly larger than the aperture of the honeycomb panel (as long as it can achieve stable support and fixation of the honeycomb panel) to avoid obstructing water flow.

[0032] To prevent the panel support structure from obstructing water flow on the substrate surface, the top surface (upper surface) of the substrate can be corrugated, or the bottom surface of the panel support structure can be corrugated or grooved, allowing water on the substrate surface to flow through the gaps formed by these corrugations or grooves. If necessary, several support pads can also be placed between the panel support structure and the substrate to create sufficient gaps between them.

[0033] The panel support structure can be connected to the honeycomb panel and substrate using any suitable connection method, such as adhesive and / or connecting components (e.g., snap-fit ​​components).

[0034] Depending on the actual needs, a rigid wire mesh 2 can be fixedly laid on top of the honeycomb panel. The rigid wire mesh can be any type of mesh suitable for the corresponding environment, such as rigid nylon wire mesh, rigid PC wire mesh, or rigid PS wire mesh. The mesh size of the rigid wire mesh can be significantly smaller than the honeycomb aperture of the honeycomb panel. Strips (frames) at the perimeter edges can be used to press the rigid wire mesh onto the honeycomb panel. These strips can be glued to the honeycomb panel or directly fastened to the substrate using screws that penetrate the honeycomb panel. Compared to laying non-woven fabric or other permeable materials, using a rigid wire mesh in conjunction with the honeycomb panel is not only more conducive to sound absorption but also effectively avoids dust accumulation and clogging.

[0035] The substrate can be designed using existing technology, and should be conducive to forming damping and reducing vibration. It should also use materials that help reduce rain noise, while meeting strength requirements and having thermal insulation / heat insulation functions, such as setting a thermal insulation / heat insulation layer inside the substrate.

[0036] This rain-absorbing and sound-absorbing structure can primarily be used as roof panels for buildings, such as light steel prefabricated buildings in riverside scenic areas. The roof can be a pitched roof or a near-pitched roof to facilitate rainwater runoff. Except for the roof surface panels (which can be called roof panels) which utilize the rain-absorbing and sound-absorbing structure of this invention, other roof structures can be installed using existing technologies. The installation of the rain-absorbing and sound-absorbing structure on the roof can be achieved using any suitable existing technology, depending on the specific roof structure. For example, when the roof is composed of several rain-absorbing and sound-absorbing structure (panels) joined together, the panels can be sealed using any suitable existing technology.

[0037] A horizontally extending water collection trough is provided along the lower edge of the roof. Water flowing from between the honeycomb panel and the substrate enters the water collection trough. The water collection trough (outlet) is connected to a rainwater pipe, or is equipped with a rainwater chain, or drains water in any other suitable manner.

[0038] Unless otherwise specified, the preferred and optional technical means disclosed in this invention can be arbitrarily combined to form several different specific embodiments when one preferred or optional technical means is a further limitation of another technical means.
