Description

Technical Field

[0001] This utility model relates to the field of space frame plate technology, specifically a sound insulation and noise reduction installation plate for large-span space frame buildings. Background Technology

[0002] Space frame panels are functional panels specifically designed for space frame structure buildings. Their core function is to block or absorb sound wave transmission through material combination and structural design, thereby reducing noise interference inside and outside the building and improving the quality of the acoustic environment. However, existing space frame panels have some shortcomings, such as: Application No.: CN202322995807.0 describes a type of space frame panel. This device can ensure the structural strength and surface flatness of the wall formed by the space frame panel, and does not require the use of templates, thus reducing construction costs. It is simple to operate and greatly improves construction efficiency. However, in actual use, this device is difficult to isolate internal or external sound, which may lead to the problem that the device is difficult to use for indoor or outdoor sound insulation. Therefore, we propose a sound insulation and noise reduction mounting plate for large-span space frame buildings to solve the problems mentioned above. Utility Model Content

[0003] The purpose of this utility model is to provide a sound insulation and noise reduction installation plate for large-span space frame buildings, so as to solve the problem mentioned in the background art that the current space frame plates on the market are difficult to isolate internal or external sound, which may lead to the problem that the equipment is difficult to soundproof indoors or outdoors.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sound insulation and noise reduction mounting plate for large-span space frame buildings, comprising a space frame plate body and connecting frames interconnected through the space frame plate bodies; The space frame panel body includes a fixed frame, and a main truss is provided inside the fixed frame. A secondary truss is installed on the outside of the main truss. A wire mesh is provided on the outside of the main truss and the secondary truss. A waterproof layer is provided on the outside of the wire mesh. A sound insulation board is provided on the outside of the waterproof layer. The main truss has a first fixed steel bar inside, and the secondary truss has a second fixed steel bar inside. The main truss and the secondary truss are arranged alternately, and the first fixed steel bar and the second fixed steel bar are arranged alternately.

[0005] By installing sound insulation panels on the upper and lower sides of the fixed frame and relying on the main truss and secondary truss to form a stable support, the firmness of the sound insulation panel installation is improved, and the two sets of sound insulation panels naturally form a gap. This design transforms the hollow space in the middle of the fixed frame into a sound insulation cavity, effectively blocking the sound transmission path and significantly enhancing the stability of the equipment's sound insulation performance. At the same time, the waterproof layer can effectively prevent water vapor from entering and avoid corrosion inside the fixed frame due to moisture, further ensuring the durability of the overall structure.

[0006] As a preferred technical solution of this utility model, the inside of the fixed frame is fixedly connected to the outside of the main truss and the secondary truss, and the outside of the fixed frame is fixedly connected to the wire mesh.

[0007] The above technical solution enables the supporting structure formed by the main truss and the secondary truss to be positioned as a whole through the fixed frame, avoiding the displacement of individual trusses under stress. At the same time, the connection between the wire mesh and the fixed frame can form a surrounding protective layer, which enhances the overall structure and provides a flat base for the subsequent waterproofing layer.

[0008] As a preferred technical solution of this utility model, a set of sealing plates is provided on each of the upper and lower sides of the fixed frame, and the sealing plates are fixedly connected to the fixed frame and the sound insulation plate.

[0009] The above technical solution enables the sealing plate to form a transitional connection between the fixed frame and the sound insulation plate. This not only improves the installation stability of the sound insulation plate through rigid connection, but also fills the gap between the two, preventing sound from penetrating through the connection gap, and enhances the overall sealing performance of the structure.

[0010] As a preferred technical solution of this utility model, the outer side of the sealing plate is provided with a fixing groove, and the fixing groove is provided with a fixing bolt inside. The outer side of the fixing frame is provided with a limiting groove, and the fixing groove is fixedly connected to the limiting groove by the fixing bolt.

[0011] The above technical solution enables the sealing plate and the fixed frame to be detachably rigidly connected by bolts, ensuring the connection strength. At the same time, the cooperation between the fixed groove and the limiting groove can achieve precise positioning, avoiding sealing failure caused by the sealing plate shifting during installation.

[0012] As a preferred technical solution of this utility model, the fixed frame is fixedly connected to the connecting frame through the limiting groove, and the connecting frame is fixedly connected to the fixed frame through bolts. Furthermore, a mortar composite surface layer is provided on both the upper and lower sides of the fixed frame, and the mortar composite surface layer is located on the outside of the sealing plate.

[0013] The above technical solutions can significantly improve the overall structure's resistance to deformation and meet the stress requirements of large-span buildings; while the mortar composite surface layer can form a protective layer on the outside of the sealing plate, enhancing the surface's wear resistance and fire resistance, and further blocking sound transmission through the difference in material density.

[0014] As a preferred technical solution of this utility model, the sound insulation board has a honeycomb-shaped sound insulation cavity inside, and the honeycomb-shaped sound insulation cavity is filled with sound insulation cotton, and the sound insulation board is fixedly connected to the waterproof layer.

[0015] The above technical solution enables the honeycomb structure to form a dual sound insulation mechanism through the air layer barrier and the sound absorption effect of the sound insulation cotton, which greatly improves the sound insulation efficiency and increases the efficiency of the device in sound insulation. As a preferred technical solution of this utility model, the waterproof layer is fixedly connected to the fixed frame by a wire mesh, and a buffer layer is provided between the waterproof layer and the sound insulation board for connection, and the buffer layer is made of polyurethane foam material.

[0016] The above technical solution enables the waterproof layer to be laid evenly with the support of the wire mesh, avoiding local damage caused by unevenness of the fixed frame surface. At the same time, it makes the connection between the waterproof layer and the sound insulation board more secure, thereby increasing the stability of the equipment during installation.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting sound insulation panels on the upper and lower sides of the fixed frame respectively, and relying on the main truss and the secondary truss to form a stable support, the sound insulation panel installation is improved, and the two sets of sound insulation panels naturally form a gap. This design transforms the hollow space in the middle of the fixed frame into a sound insulation cavity, effectively blocking the sound transmission path and significantly enhancing the stability of the equipment's sound insulation performance. At the same time, the waterproof layer can effectively prevent water vapor from entering and avoid corrosion inside the fixed frame due to moisture, further ensuring the durability of the overall structure. Furthermore, by connecting the main truss and the outer side of the secondary truss and the fixed frame, the support structure formed by the main truss and the secondary truss can be positioned as a whole through the fixed frame, avoiding the force displacement of individual trusses. At the same time, the connection between the wire mesh and the fixed frame can form a surrounding protective layer. Furthermore, by setting up a mortar composite surface layer, a protective layer can be formed on the outside of the sealing plate, enhancing the surface wear resistance and fire resistance, while further blocking sound transmission through the difference in material density.
