Description

Technical Field

[0001] This utility model relates to the field of building ground engineering technology, and in particular to a thermal insulation and soundproof flooring structure that also has crack resistance. Background Technology

[0002] In modern construction engineering, the floor is a basic component of the building, and its quality directly affects the comfort and service life of the building. Although traditional concrete floor structures have strong load-bearing capacity, they have an inherent defect: when concrete materials dry and shrink or are affected by temperature changes, internal stress will be generated, resulting in irregular cracks on the floor surface. This not only affects the aesthetics of the interior, but also reduces the durability of the floor.

[0003] As people's requirements for living quality continue to improve, the thermal insulation and sound insulation functions of flooring are receiving increasing attention. Existing technical solutions involve simply laying an insulation layer or sound insulation pad on the basis of traditional flooring. However, this simple layering method has limited functionality, especially in terms of sound insulation. It can only play a limited role in blocking airborne noise, while the isolation effect on footsteps and the impact sound of objects falling is very poor. In addition, these solutions ignore the fact that sound will propagate laterally along the wall and doorway structure, i.e., the sound bridge problem, which makes it difficult for the overall sound insulation performance to meet high standards.

[0004] Meanwhile, measures such as adding fibers or mesh to concrete to solve cracking problems are mostly passive enhancements of tensile strength, which cannot fundamentally eliminate cracks caused by shrinkage stress. Currently, there is a lack of integrated flooring structures on the market that can organically combine efficient thermal insulation, all-round sound insulation, and active crack resistance. Existing technologies have single functions or complex structures and cumbersome construction, making it difficult to meet multiple performance requirements at the same time.

[0005] Therefore, this utility model proposes a thermal insulation and soundproof flooring structure that also has crack resistance to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the existing technology, the thermal insulation and sound insulation flooring structure with crack resistance function has the problem of limited functionality, especially in sound insulation, which cannot effectively isolate impact sound and ignores the sound propagation along the side of the wall. At the same time, the concrete surface layer is prone to cracking. This utility model aims to provide a thermal insulation and sound insulation flooring structure with crack resistance function that has been improved and can effectively solve the above problems.

[0007] This utility model provides a thermal insulation and soundproof flooring structure with crack resistance, including a leveling layer, a sound insulation mechanism disposed on the leveling layer, and a crack resistance mechanism disposed on the sound insulation mechanism.

[0008] The sound insulation mechanism includes a thermal insulation sound insulation board, elastic gaskets, a keel cavity, glass wool, gypsum board, a horizontal sound insulation board, and a vertical sound insulation board. The sound insulation mechanism is arranged from bottom to top as follows: thermal insulation sound insulation board, elastic gaskets, keel cavity, and gypsum board. The keel cavity is filled with glass wool. Furthermore, the horizontal sound insulation board is laterally fixed to the thermal insulation sound insulation board, and the bottom of the vertical sound insulation board is fixedly connected to the top of the horizontal sound insulation board.

[0009] The crack-resistant mechanism includes gypsum foam concrete, high crack-resistant concrete, fiberglass mesh, and dividing joints. Specifically, the crack-resistant mechanism consists of gypsum foam concrete and high crack-resistant concrete arranged sequentially from bottom to top, with fiberglass mesh placed between the gypsum foam concrete and the high crack-resistant concrete. Dividing joints are formed on the top surface of the high crack-resistant concrete.

[0010] Preferably, the floor structure is installed inside the wall, and one side of the vertical sound insulation board abuts against the bottom front side of the wall. This arrangement effectively blocks sound from being transmitted through the wall via solids.

[0011] Preferably, the horizontal sound insulation panel is horizontally arranged below the doorway, further isolating sound transmission between the floors of different rooms.

[0012] Preferably, the present invention further includes a decorative layer, which is fixedly connected to and covers the top surface of the high crack-resistant concrete, for the purpose of aesthetic decoration and protection of the floor.

[0013] Preferably, the dividing joints are filled with elastic sealant, which can seal the dividing joints, prevent moisture penetration, and accommodate the expansion and contraction of the concrete.

[0014] Preferably, the bottom of the fiberglass mesh is fixedly connected to the top of the gypsum foam concrete, and the bottom of the groove of the dividing joint extends to the top surface of the fiberglass mesh, which enables the dividing joint to effectively cut the concrete layer and guide stress release.

[0015] Preferably, the elastic pads are fully laid on top of the thermal insulation and sound insulation board to ensure that the vibration isolation effect of the floating floor is uniform and complete.

[0016] Preferably, the keel cavity is formed by a keel frame mounted on top of the elastic gasket, and the keel frame provides a stable load-bearing foundation for the gypsum board.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem that existing floor structure sound insulation methods are singular, unable to effectively isolate impact sound and ignore the lateral propagation of sound along the wall by setting up a multi-dimensional sound insulation mechanism composed of elastic pads, keel cavity, glass wool and vertical and horizontal sound insulation panels. It achieves the technical effect of all-round and efficient isolation of impact sound and air sound, and significantly improves the quality of indoor acoustic environment.

[0019] 2. This utility model solves the problem of irregular cracks easily generated in traditional concrete floors due to their own shrinkage by using glass fiber mesh to enhance tensile strength in the crack-resistant mechanism and combining it with a combination of opening segmented joints on the high crack-resistant concrete surface to actively guide stress release. It achieves the technical effect of combining "resistance" and "release", effectively preventing cracking of the floor surface and ensuring the integrity, aesthetics and durability of the ground.

The thermal insulation and soundproof flooring structure with crack resistance includes a leveling layer 35, a sound insulation mechanism 4, and a crack-resistant mechanism 3 stacked sequentially from bottom to top.

A doorway 5 is opened at the right end of the front side of wall 1. The sound insulation mechanism 4 is used to achieve thermal insulation and sound insulation of the floor slab. The crack-resistant mechanism 3 is used to achieve crack resistance of the floor surface. The sound insulation mechanism 4 includes a thermal insulation and sound insulation board 45, an elastic gasket 44, a keel cavity 42, glass wool 43, gypsum board 41, a horizontal sound insulation board 46, and a vertical sound insulation board 47.

[0029] Please refer to Figures 1 to 4 The sound insulation mechanism 4 has a sound insulation board 45 installed on top of the leveling layer 35. Elastic pads 44 are fully laid on top of the sound insulation board 45. The keel cavity 42 is supported on top of the elastic pads 44 by a keel frame. Glass wool 43 is filled inside the keel cavity 42. Plasterboard 41 covers and is fixedly connected to the top of the keel cavity 42. The horizontal sound insulation board 46 is horizontally arranged below the door opening 5 and is laterally fixedly connected to the sound insulation board 45. One side of the vertical sound insulation board 47 abuts against the bottom front side of the wall 1. Furthermore, the bottom of the vertical sound insulation board 47 is fixedly connected to the top of the horizontal sound insulation board 46, the gypsum foam concrete 34 of the crack-resistant mechanism 3 is poured on the top of the gypsum board 41, the bottom of the fiberglass mesh 33 is fixedly connected to the top of the gypsum foam concrete 34, the high crack-resistant concrete 31 is poured on the top of the fiberglass mesh 33, the top surface of the high crack-resistant concrete 31 is provided with a dividing joint 32, the dividing joint 32 is filled with elastic sealant, and the bottom of the dividing joint 32 extends to the top surface of the fiberglass mesh 33.

[0030] As a preferred embodiment, please refer to Figure 2 The vertical sound insulation panel 47 is fixedly connected to the bottom front side of the wall 1, and the bottom of the vertical sound insulation panel 47 is fixedly connected to the top of the horizontal sound insulation panel 46. The vertical sound insulation panel 47 and the horizontal sound insulation panel 46 cut off the rigid connection between the floor structure and the wall 1 and the floor of the adjacent room, effectively blocking the lateral propagation path of sound through the solid structure.

[0031] As another preferred embodiment, please refer to Figure 1 and Figure 2 The horizontal sound insulation board 46 is not only horizontally arranged below the door opening 5, but also fixedly connected to the rear side of the thermal insulation and sound insulation board 45, forming a complete acoustic isolation for the area below the door opening 5 and the boundary of the room.

[0032] As another preferred embodiment, please refer to Figure 3 and Figure 4 The joint 32 is filled with elastic sealant. This elastic material can adapt to the expansion and contraction of concrete, maintain the seal of the joint, prevent moisture and debris from entering, and also play a buffering role.

[0033] Working principle:

[0034] First, after the leveling layer 35 is completed, the sound insulation mechanism 4 is laid. The sound insulation mechanism 4 achieves a high-efficiency sound insulation effect through the synergistic action of multiple mechanisms. The thermal insulation and sound insulation board 45 at the bottom first provides initial sound and heat insulation. The elastic pads 44 laid on top of the thermal insulation and sound insulation board 45 constitute the key core of the floating floor slab. When footsteps or objects fall from the upper floor, the elastic pads 44 can absorb the impact energy, greatly reducing the transmission of vibration to the solid structure below, thereby effectively suppressing impact noise. Above the elastic pads 44, an air layer is formed by the keel cavity 42 erected by the keel frame, utilizing air as a poor sound conductor. The material's properties significantly attenuate the propagation of airborne sound. The glass wool 43, which fills the cavity 42 of the keel, is a porous sound-absorbing material. When sound waves enter it, they are converted into heat energy due to friction and vibration, and are absorbed in large quantities, further improving the sound insulation. The gypsum board 41, which covers the top, acts as a mass block and follows the acoustic mass law to effectively block the remaining sound waves again. At the same time, the design of the vertical sound insulation board 47 and the horizontal sound insulation board 46 structurally cuts off the lateral sound transmission paths between the floor and the wall 1, the area below the doorway 5, etc., i.e., sound bridges, ensuring that sound will not bypass the vertical sound insulation system of the floor and propagate from the side, achieving all-round acoustic isolation.

[0035] After the sound insulation mechanism 4 is completed, the crack-resistant mechanism 3 is poured on the top gypsum board 41. The crack-resistant mechanism 3 prevents surface cracking by combining resistance and release. The underlying gypsum foam concrete 34 provides a certain load-bearing capacity and also serves as an auxiliary insulation layer, enhancing the overall insulation performance of the floor. The fiberglass mesh 33 laid between the gypsum foam concrete 34 and the high crack-resistant concrete 31 acts like steel reinforcement in concrete, greatly improving the tensile strength of the surface structure. When the high crack-resistant concrete 31 experiences tensile stress due to drying shrinkage, the fiberglass mesh... The 33 layer of gebrush effectively resists these stresses, serving as the first line of defense against cracking. The segmentation joints 32, poured onto the surface layer of high crack-resistant concrete 31 and cut out, are a proactive stress-relieving crack-prevention measure. Concrete shrinkage is an unavoidable physical phenomenon. As a pre-designed weak point, the segmentation joints 32 can guide shrinkage stress to this point for concentrated release, forming regular and controllable gaps. This avoids irregular, random cracks that affect aesthetics and function in other parts of the slab. Through the dual protection of material reinforcement and structural measures, this utility model effectively solves the technical problem of concrete floor cracking.
