Description

Technical Field

[0001] The present invention relates to the technical field of construction, and particularly to a novel sound insulation and vibration damping floor structure for villa construction and its manufacturing process. Background Art

[0002] In modern architectural design, especially in high-end residential buildings such as villas, people have higher requirements for the comfort and quietness of the living environment. However, traditional floor structures have many deficiencies in vibration damping and sound insulation. For example, in daily life, the floor is easily affected by mechanical vibrations such as walking and furniture movement, generating relatively large noises and affecting the comfort of the living environment. In addition, sounds between upper and lower floors are also easily transmitted through the floor structure, resulting in indoor noise interference.

[0003] Most existing floor structures adopt a simple concrete pouring method. Although they have a certain load-bearing capacity, due to the lack of effective sound insulation and vibration damping measures, vibration energy and sound are easily transmitted through the rigid structure.

[0004] Most existing floors are designed with single materials or single layers, unable to fully isolate and absorb sound waves and vibrations of multiple frequencies. Moreover, during long-term use, affected by environmental factors such as temperature and humidity, deformation may occur, making disassembly, assembly, and maintenance inconvenient. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a novel sound insulation and vibration damping floor structure for villa construction and its manufacturing process, solving the problems of being unable to fully isolate and absorb sound waves and vibrations of multiple frequencies, and being likely to deform during long-term use, making disassembly, assembly, and maintenance inconvenient.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A novel sound insulation and vibration damping floor structure for villa construction includes a support layer with multiple cross-shaped mortise and tenon installation skeletons inside and multiple support frames with composite layers installed. A plurality of limit blocks are arranged on the support layer, and an installation base is mortise and tenon connected to the plurality of limit blocks. A vibration damping lower frame is fixedly connected to the installation base. A rubber pad is installed inside the vibration damping lower frame. A vibration damping upper frame is installed on the top of the plurality of rubber pads, so that a cavity formed between the vibration damping upper frame and the vibration damping lower frame is provided with sound insulation filler. A rubber block is installed between the vibration damping upper frame and the vibration damping lower frame. A limit strip is installed on the vibration damping upper frame. An installation groove is opened at the bottom of the support frame, and the installation groove is fitted on the limit strip.

[0007] Preferably, the composite layer includes a decorative board, a sound absorption board, and a damping layer, and the decorative board, the sound absorption board, and the damping layer are arranged in the support frame from bottom to top in sequence.

[0008] Preferably, the damping layer enters the support frame in a molten state and is laid on the sound absorption board.

[0009] Preferably, a load-bearing floor slab is provided on the lower surface of the support layer for supporting the entire structure.

[0010] Preferably, a limiting rod is provided on one side of the support frame, and a plurality of the support frames are connected by mortise and tenon joints by inserting the limiting rods.

[0011] Preferably, a limiting pin is provided on one side of the support frame, and the limiting pin is inserted between two support frames and into the limiting rod.

[0012] Preferably, the top end of the limiting pin is flush with the top end of the support frame, and a decorative plate is covered on the limiting pin.

[0013] The manufacturing process of the new sound insulation and vibration damping floor slab structure for villa buildings includes the following steps; S1. Cut the combined skeleton according to the installation dimensions, place it on the load-bearing floor slab, and pour it to form the support layer. At the same time, install the limiting block on the support layer; S2. Fix a rubber pad on the vibration damping lower frame and fix the vibration damping upper frame at the other end. Then connect the vibration damping lower frame and the vibration damping upper frame through a rubber block. At the same time, fill sound insulation filler between the vibration damping lower frame and the vibration damping upper frame. The sound insulation filler is glass wool or foam material; S3. Connect the installation base at the bottom of the vibration damping lower frame with the limiting block by mortise and tenon joints, and then install the vibration damping lower frame and the vibration damping upper frame on the support layer; S4. Place the support frame on the vibration damping upper frame, make the limiting strip fit into the installation groove, fix the support frame, connect two support frames by inserting the limiting rod into the two support frames to make the two support frames connected by mortise and tenon joints, and insert the limiting pin into the support frame and the limiting rod for fixation; S5. Install the sound absorption board at the bottom of the support frame, lay a damping layer on the sound absorption board, press the decorative plate on the support frame when the damping layer is not solidified. The thickness of the damping layer is controlled at 10-15 mm, and place a heavy object on the decorative plate. After waiting for 12-36 h for the damping layer to solidify, remove the decorative plate.

[0014] Working principle: The support layer plays a load-bearing role in the entire structure. By setting a load-bearing floor slab on the lower surface of the support layer, the entire floor slab structure can bear the load of the superstructure. The vibration damping lower frame and the vibration damping upper frame are connected by rubber pads and rubber blocks. The rubber elements can absorb vibration energy and convert it into heat energy through elastic deformation and dissipate it, thereby reducing the transmission of vibration to the upper layer of the floor slab. It can effectively absorb and attenuate the vibration transmitted from the lower structure and reduce the intensity of vibration transmitted to the upper structure. The sound insulation filler in the cavity between the vibration damping upper frame and the vibration damping lower frame can effectively reduce the propagation of noise in the structure through multiple reflections and absorption of sound waves. The damping layer is laid on the sound-absorbing board, enters the support frame in a molten state, and forms a uniform damping layer after solidification. The damping material will deform, and part of the vibration energy is converted into heat energy and dissipated, thereby reducing the vibration energy transmitted to the upper structure. Through the mortise and tenon connection method, multiple components such as support frames and mounting bases are tightly combined to form a stable overall structure. The mortise and tenon connection not only helps to increase the strength and stability of the structure.

[0015] The present invention provides a novel sound insulation and vibration damping floor slab structure for villa buildings and its manufacturing process. It has the following beneficial effects: 1. In the present invention, the vibration damping lower frame and the vibration damping upper frame are connected by rubber pads and rubber blocks, which can effectively absorb and dissipate the vibration energy transmitted by the structure. Through elastic deformation, these rubber elements convert the vibration energy into heat energy and dissipate it, thereby significantly reducing the transmission of vibration to the upper layer of the floor slab, and then achieving the effect of reducing the vibration of the floor slab.

[0016] 2. In the present invention, sound insulation fillers are filled between the vibration damping lower frame and the vibration damping upper frame. These sound insulation materials can significantly reduce the propagation of noise in the structure through multiple reflections and absorption of sound waves.

[0017] 3. In the present invention, the damping layer is laid on the sound-absorbing board in a molten state, and a uniform damping layer can be formed after solidification. The material of the damping layer will deform during vibration, convert part of the vibration energy into heat energy and dissipate it, thereby improving the overall vibration damping effect of the floor slab structure and reducing material waste at the same time.

[0018] 4. In the present invention, a limit pin (14) is also provided on one side of the support frame (4). The limit pin is inserted between two adjacent support frames and further inserted into the limit rod (13), thereby strengthening the fixing effect of the support frame. Through the mutual cooperation of the mortise and tenon connection, it can be quickly installed in place or disassembled. This modular design improves the flexibility of the floor slab structure, is convenient for on-site adjustment and replacement, and is also convenient for later maintenance and renovation.
