Description

Technical Field

[0001] This utility model relates to the field of thermal insulation board technology, specifically to a polystyrene particle cement sandwich thermal insulation board structure. Background Technology

[0002] Polystyrene particle cement sandwich insulation board is a new type of wall material, mainly composed of polystyrene foam, concrete and fiberglass mesh. This material has the characteristics of being lightweight and high-strength, which can effectively reduce the overall weight of the building and reduce the structural cost. At the same time, it has high strength and load-bearing capacity, and can adapt to the laying needs of various base materials and equipment pipelines.

[0003] The existing polystyrene particle cement sandwich insulation board has a polystyrene particle cement core layer in the middle and cement surface layers on both sides. This structure makes it easy for density gradients or local agglomeration to occur when polystyrene particles are mixed with cement, resulting in uneven density inside the core layer. This leads to poor insulation performance and hardness of the core layer. At the same time, the hydrophobicity of the polystyrene particle surface makes it difficult to bond with the cement paste, and the core layer is prone to peeling off from the surface layer after long-term use. Therefore, we propose a polystyrene particle cement sandwich insulation board structure. Utility Model Content

[0004] The purpose of this utility model is to provide a polystyrene particle cement sandwich insulation board structure to solve the problem mentioned in the background art that the existing polystyrene particle cement sandwich insulation board structure has a middle polystyrene particle cement core layer and cement surface layers on both sides. This structure causes density gradients or local agglomeration when polystyrene particles are mixed with cement, resulting in uneven density inside the core layer. This makes the insulation performance and hardness of the core layer poor. At the same time, the hydrophobicity of the polystyrene particle surface and the poor adhesion to the cement paste make the core layer prone to peeling off from the surface layer after long-term use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polystyrene particle cement sandwich insulation board structure, comprising:

[0006] A first polystyrene particle cement core layer is provided, and a second polystyrene particle cement core layer is installed at both ends of the first polystyrene particle cement core layer. A cement surface layer is installed on the side of the second polystyrene particle cement core layer away from the first polystyrene particle cement core layer. Reinforcing ribs are provided inside the first polystyrene particle cement core layer. A connecting groove is provided inside the second polystyrene particle cement core layer. The connecting groove is filled with cement slurry and a connecting plate is installed inside. A connecting rod is installed on the side of the connecting plate near the cement surface layer.

[0007] As a preferred embodiment of the polystyrene particle cement sandwich insulation board structure of this utility model, the reinforcing ribs are evenly distributed along the interior of the first polystyrene particle cement core layer, and the reinforcing ribs sequentially penetrate the interior of the first polystyrene particle cement core layer and the second polystyrene particle cement core layer.

[0008] In a preferred embodiment of the polystyrene particle cement sandwich insulation board structure of this utility model, the cement surface layer is fixedly connected to the connecting rod, the connecting groove has a convex shape, and the shape and size of the connecting plate are smaller than the shape and size inside the connecting groove.

[0009] As a preferred embodiment of the polystyrene particle cement sandwich insulation board structure of this utility model, the density of polystyrene particles in the first polystyrene particle cement core layer is greater than the density of polystyrene particles in the second polystyrene particle cement core layer.

[0010] As a preferred embodiment of the polystyrene particle cement sandwich insulation board structure of this utility model, the first polystyrene particle cement core layer further comprises:

[0011] The mating protrusion is integrally fixedly installed on the left side of the first polystyrene particle cement core layer, and the right side of the first polystyrene particle cement core layer is provided with a mating groove.

[0012] Compared with the prior art, this utility model provides a polystyrene particle cement sandwich insulation board structure, which has the following beneficial effects:

[0013] This invention utilizes a first polystyrene particle cement core layer with high polystyrene particle density and a second polystyrene particle cement core layer with low polystyrene particle density to form a gradient insulation structure. This gradient structure can optimize the balance between insulation and strength; the low-density layer may provide better structural support, while the high-density layer is lighter and has better insulation performance. This ensures the strength of the board without sacrificing insulation performance. In addition, the density gradient may reduce the thermal bridging effect because materials of different densities have different thermal conductivity, and the layered arrangement may reduce the heat transfer path and improve the overall insulation efficiency.

[0014] This invention sets up a connecting groove and fills it with cement grout. After the cement grout solidifies, its shape matches the shape inside the connecting groove, thereby fixing the connecting rod and connecting plate inside the connecting groove and preventing the cement surface layer from falling off the second polystyrene particle cement core layer.

The gradient structure may optimize the balance between insulation and strength; the low-density layer may provide better structural support, while the high-density layer is lighter and has better insulation effect; this ensures the strength of the board without sacrificing insulation performance; in addition, the density gradient may reduce the thermal bridging effect, because materials with different densities have different thermal conductivity, and the layered arrangement may reduce the heat transfer path and improve the overall insulation efficiency; at the same time, by setting a connecting groove 6 and filling it with cement grout 8, after the cement grout 8 solidifies, its shape matches the shape inside the connecting groove 6, thereby fixing the connecting rod 5 and the connecting plate 7 inside the connecting groove 6, thus preventing the cement surface layer 3 from falling off the second polystyrene particle cement core layer 2.

[0022] Furthermore:

[0027] In this implementation scheme: when the cement surface layer 3 is installed on the second polystyrene particle cement core layer 2, the connecting rod 5 and the connecting plate 7 can be inserted into the interior of the connecting groove 6.

[0035] Working principle: When producing this polystyrene particle cement sandwich insulation board structure, firstly, when producing the second polystyrene particle cement core layer 2 using a mold, reinforcing ribs 4 are inserted into the interior of the second polystyrene particle cement core layer 2. Then, the second polystyrene particle cement core layer 2 and reinforcing ribs 4 are placed in the mold.

Next, connecting grooves 6 corresponding to the connecting plates 7 are opened on the surface of the second polystyrene particle cement core layer 2. Cement slurry 8 is injected into the interior of the connecting grooves 6. Then, the cement surface layer 3 is bonded to the second polystyrene particle cement core layer 2 with cement or adhesive, so that the connecting rods 5 and connecting plates 7 are inside the connecting grooves 6.
