Description

Technical Field

[0001] This invention relates to the field of building sound insulation and thermal insulation technology, specifically to a sound insulation structure for filling the interior of a steel frame building. Background Technology

[0002] The sound insulation structure inside a steel frame building refers to filling the cavities of a steel frame building with sound insulation materials to reduce noise transmission. These materials have good sound absorption and sound insulation properties. Filling the sound insulation structure can effectively block external noise from entering the room, while reducing the impact of indoor noise on the external environment. The density, thickness and installation method of the sound insulation material will affect the sound insulation effect. The sound insulation structure can also be combined with fireproofing, heat insulation and other functions to improve the overall performance of the building.

[0003] In the prior art, patent document CN116240989B discloses a temporary building sound insulation structure and its construction process, including a sound-insulating and fire-resistant core and sound-insulating support layers disposed on both sides of the sound-insulating and fire-resistant core. The sound-insulating and fire-resistant core includes a steel frame and sealing plates fixed to both sides of the steel frame. The process includes assembling the sound-insulating and fire-resistant core, assembling the sound-insulating support layers, splicing, installing auxiliary components, and filling. This invention, by setting a sound-insulating and fire-resistant core and filling the cavity formed by the steel frame and sealing plates with water, on the one hand, uses water as a "middle partition" between the two sound-insulating support layers. Combined with the high specific heat of water, this structure can delay the change of internal temperature when the external temperature changes, thus increasing the thermal insulation performance. On the other hand, by utilizing the flammability of the sealing plates, when a fire occurs, the sealing plates will burn, thereby creating holes in the internal cavity, and water will flow out through the holes, achieving an auxiliary fire extinguishing effect and increasing safety performance. However, the above-mentioned technical solutions, which use a single sound insulation material, cannot effectively block noise of different frequencies. Furthermore, gaps are easily formed at the connection between the material and the steel structure, resulting in obvious sound insulation blind spots. Moreover, the structural stability is insufficient, and the simple fixing method between the sound insulation material and the steel frame structure makes it prone to loosening and falling off under the influence of building settlement and vibration over a long period of time, affecting the sound insulation effect and building safety. In addition, the synergy between sound insulation and heat insulation is poor, focusing only on the sound insulation function and lacking adaptation to heat insulation needs, thus failing to take into account the building's energy-saving requirements. Based on this, the present invention provides a sound insulation structure for filling the interior of a steel frame building to solve the problems mentioned in the background art. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing a sound insulation structure for filling the interior of a steel frame building to solve the problems of single sound insulation structure, poor synergy between sound insulation and heat insulation, weak connection with the steel structure, and easy aging and detachment.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a sound insulation structure for filling the interior of a steel frame building, including a sound insulation connection structure, wherein the sound insulation connection structure includes two steel structure columns, and a connecting plate is welded to one side of the inner wall of the two steel structure columns through multiple connecting frames, and the inner wall of the steel structure columns is filled with an internal polyurethane filling layer. A sound insulation assembly structure is provided between the two steel structure columns. The sound insulation assembly structure includes a sealing plate fixed between two connecting plates, and a top mounting bracket is installed on the top of each of the sealing plates. The sealing plates are arranged in groups of four, and each group of sealing plates has an internal mounting structure on its inner wall.

[0006] The beneficial effects of adopting the above-mentioned further scheme are as follows: the two steel structural columns serve as load-bearing components, supporting the building load and providing an installation base for the sound insulation structure; multiple connecting frames are welded to one side of the inner wall of the two steel structural columns, connecting and fixing the connecting plates, strengthening the lateral integrity of the two steel structural columns, avoiding spacing deviation due to building settlement, and providing installation support points for the sound insulation assembly structure; the internal polyurethane filling layer is filled into the inner wall of the steel structural columns, achieving preliminary sound insulation and heat insulation. Polyurethane material has excellent sound absorption and heat insulation properties, which can effectively block some noise, while filling the internal gaps of the steel structural columns, enhancing the structural airtightness, and laying the foundation for subsequent multi-layer sound insulation; the connecting plates are welded and fixed to the inner wall of the steel structural columns through the connecting frames, connecting the sealing plates in the sound insulation assembly structure, providing a flat and firm installation surface for the sealing plates, and ensuring the connection between the sound insulation assembly structure and the steel structural columns; the pouring layer is laid on the outer wall of the installation block, made of high-strength grouting material, fixing the installation block, filling the gaps between the installation block and the surrounding structure, strengthening the bottom connection stability, and further improving the structural airtightness, assisting in blocking noise transmission.

[0007] The beneficial effects of this invention are: 1) This invention utilizes a multi-layer composite sound insulation system consisting of a polyurethane filling layer, XPS board, polyurethane board, asbestos board, and liquid foam seal. Different materials are used to specifically block noise at different frequencies. Combined with a fully enclosed cavity design, this invention completely solves the problems of limited sound insulation effect and sound leakage in traditional single-material systems. At the same time, the materials have both sound insulation and heat insulation properties, achieving synergistic effects of sound insulation and heat insulation, and meeting the dual needs of building energy conservation and acoustics.

[0008] 2) This invention strengthens the overall integrity of the sealing plate by stabilizing the anchor rod and end nut, fixes the internal placement frame by locking block, enhances the connection between the anchor hook and the pouring layer and the building structure, and improves the connection strength between the upper and lower structures by the interlocking design of the installation block and the slot. All components work together to resist the impact of building settlement and vibration, prevent the sound insulation structure from loosening and falling off, and meet the long-term use needs of buildings.

[0009] 3) The components of this invention adopt a modular prefabrication design. The sealing plate, mounting frame, and placement frame can all be prefabricated in the factory in advance. On-site assembly only requires simple processes such as welding, snap-fitting, and bolt fixing, which greatly shortens the on-site construction time. The layered filling material is arranged in an orderly manner through the internal placement frame, without the need for complicated laying process. At the same time, the installation position is precise, which can effectively avoid material waste and uneven laying. During subsequent maintenance, the corresponding modules can be disassembled individually without affecting the overall structure, thus improving the convenience of operation and maintenance.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, a fixing frame is installed on the outer wall of the sealing plate. The fixing frame is made of channel steel welded into a C shape, and the fixing frame is fully welded to the outer wall of the sealing plate and the bottom end of the top mounting bracket.

[0012] Furthermore, the top mounting frame is made of flat steel welded together, is square in shape, and has a top sealing plate installed inside. The top of the top sealing plate is fixedly connected to the mounting frame. The mounting frame is square in shape and has slots inside. Multiple anchor hooks are fixedly connected at equal intervals to the outer wall of the mounting frame. The multiple anchor hooks are made of galvanized round steel welded to the outer wall of the mounting frame and are used in an irregular distribution.

[0013] Furthermore, a bottom end sealing plate is installed at the bottom end of the sealing plate, and a mounting block is welded to the bottom end of the bottom end sealing plate. The mounting block is made of carbon steel and has stripes cast on its surface to facilitate engagement with the slots opened inside the mounting frame and increase friction. The outer walls of the multiple mounting blocks are covered with a casting layer.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: the sealing plate is fixed between two connecting plates, forming an internal installation space in groups of four. It is made of fireproof and soundproof material, forming a soundproof cavity to support the internal installation structure, while also possessing certain sound insulation performance. The fixing frame is C-shaped, welded from channel steel, and fixed to the outer wall of the sealing plate and the bottom of the top mounting bracket by full welding. This strengthens the structural rigidity of the sealing plate, prevents deformation, and improves the connection strength between the sealing plate and the top mounting bracket, ensuring no looseness or gaps at the joint and blocking noise leakage. The top mounting bracket is a square structure welded from flat steel, connecting the sealing plate and the mounting bracket, providing installation support for the top structure. The top sealing plate is installed inside the top mounting bracket, sealing the top gap and providing a fixed foundation for the mounting bracket. The mounting bracket is square, fixed to the top of the top sealing plate, and has internal openings... The slots, which engage with the bottom mounting blocks, enable precise docking and fixation of the upper and lower structures. They also provide a mounting platform for the anchor hooks, which are made of galvanized round steel welded to the outer wall of the mounting frame. These hooks are irregularly distributed, enhancing the connection between the mounting frame and the surrounding poured concrete layer and building structure, preventing loosening and displacement of the mounting frame, and improving overall structural stability. The slots are located inside the mounting frame and engage with the mounting blocks for quick positioning and docking. The mounting blocks, made of carbon steel with cast stripes on the surface, are welded to the bottom of the bottom sealing plate. By interlocking with the slots, they enhance the connection strength between the upper and lower structures. The surface stripes increase friction with the inner wall of the slots, preventing relative slippage and providing attachment points for the poured concrete layer. Together with the top sealing plate, they form a closed soundproof cavity and provide a welding base for the mounting blocks, ensuring a secure bottom connection and preventing soundproofing material from detaching from the bottom.

[0015] Furthermore, the internal installation structure includes multiple stabilizing anchors penetrating the outer wall of the sealing plate. The multiple stabilizing anchors are equally spaced and distributed in a rectangular shape, providing fulcrum for the connection between sealing plates and the installation of internal components.

[0016] Furthermore, each of the outer walls of the plurality of stabilizing anchor rods is threaded with an end nut, and the plurality of end nuts are threaded to the outer wall of the sealing plate for fixation.

[0017] Furthermore, each set of sealing plates has locking blocks fixedly installed on both sides of its inner wall, and multiple locking blocks have internal placement racks snapped into their inner walls, with multiple internal placement racks placed coaxially side by side.

[0018] Furthermore, each of the outer walls of the plurality of stabilizing anchor rods is threaded with an end nut, and the plurality of end nuts are threaded to the outer wall of the sealing plate for fixation.

[0019] Furthermore, the inner wall of the inner shelf on one side is filled with XPS board for internal sound insulation, the inner wall of the inner shelf in the middle is filled with polyurethane board for sound and heat insulation, and the inner wall of the inner shelf on the other side is filled with asbestos board.

[0020] Furthermore, each set of sealing plates has an inner groove at the bottom of multiple internal placement racks, and the inner wall of the inner groove is filled with liquid polyurethane foam.

[0021] The beneficial effects of adopting the above-mentioned further solution are as follows: The stabilizing anchor rods penetrate the outer wall of the sealing plate, distributed in a rectangular pattern at equal intervals, providing fulcrums for the connection between sealing plates and the installation of internal components. The end nuts are threaded onto both sides of the stabilizing anchor rod's outer wall and fixed against the outer wall of the sealing plate, locking the anchor rod and ensuring a firm connection to the sealing plate. Simultaneously, the sealing plate spacing can be finely adjusted by adjusting the tightness of the nuts. Locking blocks are fixedly installed on both sides of the inner wall of each set of sealing plates, engaging and fixing the internal placement frame, ensuring accurate and secure installation of the placement frame and preventing displacement due to building vibrations. The internal placement frames are coaxially arranged side-by-side on the inner wall of the locking blocks, layering and supporting different sound and heat insulation materials, achieving an orderly arrangement of materials while providing protection against direct stress damage. The placement frames in different positions are adapted to the characteristics of different materials, maximizing sound insulation. For thermal insulation, XPS boards are placed on the inner wall of one side of the internal shelf to enhance internal sound insulation performance. XPS boards have excellent sound absorption and sound insulation effects and can effectively block mid-to-high frequency noise. The inner wall of the internal shelf in the middle is filled with polyurethane boards to achieve synergistic sound insulation and thermal insulation. Polyurethane boards have both sound absorption and heat insulation properties, filling the performance gap between XPS boards and asbestos boards. The inner wall of the internal shelf on the other side is filled with asbestos boards to enhance fireproof and sound insulation performance. Asbestos boards have excellent fire resistance and flame retardancy, which can improve the building's fire resistance rating while providing sound insulation. The inner groove is opened at the bottom of each set of sealing boards in the internal shelf, and the inner wall is filled with liquid polyurethane foam to fill the bottom gap and achieve a seamless seal. At the same time, after the polyurethane foam cures, it can further fix the internal shelf and filling material, prevent the bottom from loosening, and block noise leakage from the bottom gap.
