The full name is lightweight panel for building partitions, and it is a primary material for non-load-bearing interior partitions in general industrial, residential, and public buildings. Partition wall panels in building construction serve multiple functions, including space division, sound insulation, thermal insulation, fire safety, seismic rigidity, decoration, and lightweight efficiency.

[0003] The existing partition wall panels used in building construction are hollow cement partition wall panels. These hollow cement partition wall panels have the following defects: (1) Although hollow cement partition wall panels can reduce the transmission of noise to a certain extent, the sound insulation effect is not ideal in situations where high sound insulation is required, and additional measures may be needed to improve the sound insulation effect. (2) Existing hollow cement partition wall panels are heavy, which increases the difficulty of transportation and installation. (3) Hollow cement partition wall panels are prone to cracking and deformation after a period of use. In addition, hollow cement partition wall panels are also easily affected in high temperature or humid environments, resulting in a short service life. (4) As a lightweight building material, hollow cement partition wall panels have weak thermal insulation performance and a large thermal conductivity coefficient, resulting in poor thermal insulation performance. In cold regions, additional thermal insulation materials or other thermal insulation measures may be required. Therefore, this utility model provides a steel wire mesh expanded perlite sandwich partition wall panel to ensure that the partition wall panel has good sound insulation, lightness, high flexural strength, long service life, and good thermal insulation effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model is based on, as follows Figure 1-5 A steel wire mesh frame expanded perlite sandwich partition wall panel is provided, as detailed below:

[0027] Example 1

[0028] This embodiment provides a steel wire mesh expanded perlite sandwich partition wall panel, including a cement polymer composite modified expanded perlite mixture board 1, with mesh layers 2 on both sides of the cement polymer composite modified expanded perlite mixture board 1, and web wire strips 3 uniformly embedded inside the cement polymer composite modified expanded perlite mixture board 1.

[0029] In this embodiment, "both sides" refers to the two opposite sides of the largest surface area of ​​the cement polymer composite modified expanded perlite mixture slab 1, used to divide different spaces within a building. The polymer includes polypropylene short fibers, polyvinyl alcohol, methylcellulose, etc.

[0030] Expanded perlite is a natural acidic glassy volcanic lava, a non-metallic mineral, which includes perlite, pitchstone, and obsidian, differing only in their water of crystallization content. Because its volume expands rapidly by 4 to 30 times under high-temperature conditions of 1000–1300℃, it is collectively referred to as expanded perlite. Expanded perlite has the following advantages: (1) Lightweight: Expanded perlite has a low density, with a volumetric dry density of about 250 kg / m³, which makes it easier to handle and install during use; (2) Thermal insulation: Due to its porous structure, expanded perlite has good thermal insulation performance and can effectively reduce heat transfer; (3) Sound insulation: The porous structure of expanded perlite gives it excellent sound absorption effect, with a sound insulation coefficient greater than 45 dB, making it suitable for places that require sound insulation; (4) Fire resistance: Expanded perlite is a Class A non-combustible inorganic thermal insulation material with good fire resistance and can maintain its integrity at high temperatures; (5) Durability: Expanded perlite has a long service life, usually exceeding 50 years, which can be the same as the life of the building, and it is not easy to age.

[0031] This embodiment of a steel wire mesh expanded perlite sandwich partition wall panel includes a cement polymer composite modified expanded perlite mixture board 1. This board is made by mixing cement, polymer and expanded perlite, and has a certain strength, as well as fire resistance, heat insulation and sound absorption. In addition, the addition of polymer increases the bonding and integration of the cement polymer composite modified expanded perlite mixture board 1.

[0032] The cement itself has strength. By uniformly embedding the web strips 3 inside the board 1 made of cement polymer composite modified expanded perlite mixture, and providing mesh layers 2 on both sides, the tensile strength and load-bearing strength of the partition wall board in this embodiment are further increased, making the partition wall board of this utility model have strong integrity and is lighter and easier to transport and install than the existing hollow cement partition wall board.

[0033] Example 2

[0034] In this embodiment, the web strip 3 is a W-shaped steel wire. The plate 1, made of cement polymer composite modified expanded perlite mixture, is uniformly embedded with W-shaped steel wires. The specific embedding structure of the W-shaped steel wires is as follows: Figure 2 and 5 As shown, different web threads 3 can be cross-welded and embedded into the plate 1 made of cement polymer composite modified expanded perlite mixture. Preferably, the diameter of the web threads 3 in this embodiment is 2.2 mm.

[0035] The rest is the same as in Example 1.

[0036] Example 3

[0037] In this embodiment, the web strip 3 protrudes 10mm from both sides of the cement polymer composite modified expanded perlite mixture plate 1, and the mesh layer 2 on both sides of the cement polymer composite modified expanded perlite mixture plate 1 is located at the end of the protruding web strip 3, and the mesh layer 2 is welded to the end of the web strip 3.

[0038] The rest is the same as in Example 2.

[0039] In this embodiment, mesh layers 2 are welded to both ends of the web wire 3. Since the web wire 3 is selected as a W-shaped steel wire, the web wire 3 and the mesh layers 2 at both ends form a triangular mesh structure, making the resulting partition wall structure more stable and solid.

[0040] Example 4

[0041] In this embodiment, the mesh layer 2 includes several galvanized mesh sheets 4, which are spaced apart at the ends of the web wire strips 3, such as... Figure 1 and 4 As shown, each galvanized wire mesh 4 has a mesh length of 50mm, a width of 50mm, and a thickness of 2mm.

[0042] The rest is the same as in Example 3.

[0043] In this embodiment, the galvanized wire mesh 4 has a galvanized outer surface, which can prevent rust and increase the service life of the galvanized wire mesh 4.

[0044] In this embodiment, the galvanized wire mesh 4 is spaced apart, forming a mesh layer 2. This increases structural strength and bending resistance while saving materials, reducing costs, and improving the lightweight nature of the resulting partition wall panel.

[0045] Example 5

[0046] This embodiment also includes two layers of cement plaster 5, which are disposed on both sides of the cement polymer composite modified expanded perlite mixture board 1. The cement plaster 5 is disposed through the mesh of the galvanized mesh 4 on the corresponding side. The cement plaster 5, the galvanized mesh 4 on the corresponding side, the side of the cement polymer composite modified expanded perlite mixture board 1, and the protruding web wire strip 3 are bonded together to form an integral whole.

[0047] Preferably, the maximum thickness of the cement plaster layer 5 in this embodiment is 50mm.

[0048] Preferably, the thickness of the cement polymer composite modified expanded perlite mixture plate 1 in this embodiment ranges from 20 to 200 mm.

[0049] The rest is the same as in Example 4.

[0050] In this embodiment, the web strip 3 protrudes 10mm from both sides of the cement polymer composite modified expanded perlite mixture board 1, leaving space for the cement plaster layer 5. This allows the galvanized wire mesh 4 to be embedded within the cement plaster layer 5. The cement plaster layer 5 is waterproof and moisture-proof, further preventing the web strip 3 or the galvanized wire mesh 4 from rusting and improving the service life of the partition board. At the same time, the cement plaster layer 5 can further increase the thermal insulation effect.

[0051] Example 6

[0052] The cement polymer composite modified expanded perlite mixture is used to make a board 1. Except for the mesh layer 2, all four sides are beveled, with opposite sides parallel to each other. The four beveled surfaces are inclined at an angle of 45 degrees. Figure 3 As shown.

[0053] The rest is the same as in Example 1.

[0054] In practical use, the partition wall of this utility model needs to be combined with multiple partition walls to form a complete wall for spatial isolation, such as... Figure 4 As shown, the structure of two cement polymer composite modified expanded perlite mixtures connected in contact as slab 1 is illustrated. The close contact of the inclined surfaces prevents the formation of a through crack 6 (referring to a continuous, highly penetrating crack, such as...). Figure 7 As shown, and Figure 4 (To create a contrast between the middle and lower structures) ensures the strength and durability of the structure and avoids affecting the overall stability of the formed wall. Figure 6 To form a sloping surface, a cement polymer composite modified expanded perlite mixture is used to make a slab 1, which is then combined with... Figure 3 To create a contrast.

[0055] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model. The technical content for which protection is sought in the present utility model has been fully recorded in the technical requirements.
