Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to an improved EPS particle lightweight partition wall panel. Background Technology

[0002] Existing EPS particle lightweight partition wall panels use a light steel keel frame with calcium silicate board, cement fiber board, or diatomaceous earth board on both sides. The side panels and the keel frame form a cavity. Depending on the wall height, 3-5 grouting holes are opened on one side of the keel frame. EPS particle concrete is placed upright on the side of the frame and injected through the grouting holes. After the grout solidifies, it forms an integral wall panel structure with the keel and the panel. This type of light steel panel has the following problems: the strength of the keel structure weakens after the holes are opened; the grout must have high fluidity to be injected through the holes, and a large proportion of cement and water needs to be added to the EPS particles, resulting in a large wall density; the operation of injecting EPS particle concrete grout into the sealed cavity is difficult, and the filling and density cannot be guaranteed; the thermal insulation and sound insulation performance of the panel cannot be guaranteed.

[0003] Chinese patent CN208533777U discloses a novel high-strength partition wall panel, comprising a partition wall panel body, which includes a cement mortar surface layer, a rubber layer, and a melamine board layer arranged sequentially from the inside out. A steel plate structural component is disposed within the cement mortar surface layer. The steel plate structural component includes two vertical thin steel plates and several horizontal thin steel plates, with the two vertical thin steel plates connected to each other. The several horizontal thin steel plates are sequentially connected to form a sawtooth structure. Each horizontal thin steel plate has several through holes. A toothed protrusion is provided in the middle of one end face of the partition wall panel body, and a corresponding recessed structure is provided in the middle of the other end face to cooperate with the toothed protrusion. This utility model has a simple structure and reasonable design, greatly improving the strength of the partition wall panel while minimizing weight. Its ingenious structural design provides strong impact resistance, good seismic performance, and convenient installation, making it suitable for widespread application.

[0004] However, this technical solution involves sequentially setting a rubber layer and a melamine board layer around the outer periphery of the cement mortar surface. After prolonged use, this three-layer structure may crack, resulting in insufficient structural strength of the entire board. Furthermore, the presence of protrusions and through holes increases the complexity of construction, making it time-consuming, labor-intensive, and costly. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an improved EPS particle lightweight partition wall panel. By installing reinforcing components between the frame and the mortar surface layer, it can disperse stress and prevent cracking of the cement mortar surface layer and concrete layer caused by shrinkage or temperature changes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An improved EPS particle lightweight partition wall panel includes: a frame for shaping, a concrete layer disposed inside the frame, a cement mortar surface layer disposed on one side of the frame, a fixing panel disposed on the other side of the frame, and a reinforcing member disposed between the cement mortar surface layer and the frame.

[0008] Preferably, the skeleton, the fixing panel, and the reinforcing member are formed into a semi-closed cavity.

[0009] Preferably, the reinforcing member is a steel wire mesh.

[0010] Preferably, the frame and the fixed panel are fixedly connected by a number of fasteners.

[0011] Preferably, the skeleton has a mesh-like internal structure.

[0012] Preferably, each end of the frame is provided with a tongue and groove joint for easy installation.

[0013] Preferably, the concrete layer is cast from EPS particle lightweight concrete.

[0014] Preferably, the material of the fixing panel is calcium silicate.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) This utility model introduces concrete into a semi-closed cavity formed by the skeleton, fixed panel and reinforcing component, so that the three are tightly combined. The reinforcing component is made of wire mesh, which can effectively disperse stress, prevent the cement mortar surface layer and concrete layer from cracking, improve the durability of the wall, and the wire mesh, after being combined with the skeleton and concrete layer, forms a composite structure, which significantly improves the tensile, compressive and bending strength of the wall.

[0017] (2) By setting the inside of the frame to be grid-like, the load can be evenly distributed on the frame, which improves the compressive, bending and shear strength of the board, making the partition wall more stable and durable. The grid structure has good toughness and ductility, which can effectively absorb earthquake energy, reduce earthquake damage to the wall, and improve the earthquake resistance of the building.

[0018] (3) By using calcium silicate to make a fixed panel, the fire resistance and water resistance of the panel are improved, thereby ensuring the safety of the board. It has low density and light weight, but high strength, which can effectively reduce the overall weight of the partition wall board and provide sufficient support.

[0019] (4) The present invention provides tongue and groove joints at the ends of the frame for easy installation, which makes the splicing of the boards more precise, reduces installation errors, and ensures that the joints are flat.

[0020] In summary, this utility model has the advantages of high structural strength, good durability, long service life, strong earthquake resistance and low cost. Attached Figure Description

[0029] Example

[0030] like Figure 1-6 As shown, this embodiment provides an improved EPS particle lightweight partition wall panel, including: a frame 1 for shaping, a concrete layer 2 disposed inside the frame 1, a cement mortar surface layer 3 disposed on one side of the frame 1, a fixing panel 4 disposed on the other side of the frame 1, and a reinforcing member 5 disposed between the cement mortar surface layer 3 and the frame 1. Concrete is injected from one side of the reinforcing member 5. The frame 1 does not need to have additional holes, can withstand more loads, ensures the strength of the frame 1, and makes the structural strength of the entire panel higher. In addition, the reinforcing member 5 can disperse stress and prevent the cement mortar surface layer 3 and the concrete layer 2 from cracking due to shrinkage or temperature changes.

[0031] The frame 1, the fixed panel 4, and the reinforcing member 5 are formed into a semi-closed cavity 6. Concrete is introduced into the semi-closed cavity 6 to tightly bind the three together, thereby ensuring the structural strength of the panel.

[0032] Meanwhile, the reinforcing member 5 is a wire mesh, the size of which is adapted to the skeleton 1, which facilitates casting. The wire mesh can effectively disperse stress and prevent cracking of the cement mortar surface layer 3 and concrete layer 2 caused by shrinkage or temperature changes, thereby improving the durability of the wall. After the wire mesh is combined with the skeleton 1 and concrete layer 2, a composite structure is formed, which significantly improves the tensile, compressive and bending strength of the wall.

[0033] In this embodiment, the frame 1 is typically made of light steel, which has good toughness and ductility and can absorb energy during earthquakes, reducing damage to the wall.

[0034] In this embodiment, the frame 1 and the fixed panel 4 are fixedly connected by a number of fasteners 41, and the introduction of concrete further ensures the stability and firmness between the frame 1 and the fixed panel 4, ensuring the structural strength of the plate and thus extending its service life.

[0035] In this embodiment, the skeleton 1 has a mesh-like structure inside. The mesh-like skeleton 1 can evenly distribute the load, improve the compressive, bending and shear strength of the board, make the partition wall more stable and durable, and the mesh-like structure has good toughness and ductility, which can effectively absorb seismic energy, reduce the damage of earthquakes to the wall, and improve the building's seismic resistance.

[0036] In this embodiment, each end of the frame 1 is provided with a tongue and groove joint 11 for easy installation, which makes the splicing of the panels more precise, reduces installation errors, and ensures that the joints are flat.

[0037] Of course, the concrete layer 2 is cast from EPS particle lightweight concrete. EPS particle concrete does not require high fluidity, so less cement can be added to reduce the density of the wall panel. Then, it is vibrated and compacted to ensure that the panel, frame 1, lightweight concrete and wire mesh can be tightly bonded, thereby ensuring that the structural strength of the panel is high enough and the thermal insulation, heat insulation and sound insulation performance are also fully guaranteed.

[0038] In addition, the fixed panel 4 is made of calcium silicate, which has low density and light weight, but high strength, which can effectively reduce the overall weight of the partition wall panel while providing sufficient support. Calcium silicate is a non-combustible material with good fire resistance, which can effectively delay the spread of fire and improve the fire safety of the building. Calcium silicate board also has good moisture resistance and is not easy to deform or mold even in humid environments, making it suitable for use in places with high humidity such as bathrooms and kitchens.

[0039] The working process of this embodiment is as follows: First, the skeleton 1 is welded into shape. After welding, a fixing panel 4 is laid on one side of the skeleton 1, and a wire mesh is spot-welded on the other side. Then, the side of the skeleton 1 with the fixing panel 4 is placed face down and flat on the vibration platform. EPS particle lightweight concrete is injected into the semi-closed cavity 6 formed by the skeleton 1, the fixing panel 4 and the wire mesh through the holes of the upper wire mesh. After compaction, a cement mortar surface layer 3 is poured on the upper part of the wire mesh. Finally, it is smoothed and cured into shape.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
