Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a prefabricated partition wall panel with a light steel frame and light concrete. Background Technology

[0002] In recent years, with the rapid development of industrialized construction and prefabricated buildings, prefabricated partition walls have been widely used in interior partition systems due to their advantages such as convenient construction and energy conservation and environmental protection. Traditional prefabricated partition walls are mostly made of reinforced concrete or lightweight aggregate concrete, which, while possessing certain strength and durability, suffers from problems such as heavy weight, low installation efficiency, and limited functionality. Especially when addressing the integrated needs of modern buildings for sound insulation, thermal insulation, wiring, and other functions, traditional panels appear structurally bulky and lack adaptability, making it difficult to meet the comprehensive performance requirements of green and intelligent buildings for wall materials.

[0003] In existing technologies, there are prefabricated partition wall panel solutions that combine a light steel frame with lightweight concrete, such as the prefabricated partition wall panel based on a light steel frame and lightweight concrete disclosed in CN206581451U. This solution achieves a certain degree of lightweighting and functional integration of the wall by setting up a template, frame, and foamed concrete filling layer. However, this structure still has several obvious drawbacks: First, cable routing must be achieved through pre-set wiring holes, with fixed positions that cannot be flexibly adjusted, making later modifications or repairs extremely inconvenient; second, the frame connection relies on various special connectors (such as L-shaped, U-shaped, clamps, etc.), resulting in a complex structure and cumbersome installation procedures, which not only increases manufacturing costs but also affects construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated partition wall panel with a light steel frame and light concrete, which can overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, a precast partition wall panel with a light steel frame and light concrete is provided, including a partition wall panel body. Connecting flanges are fixedly connected to the interior of the upper and lower side walls of the partition wall panel body. A support frame is installed in the middle of the partition wall panel body. A cross support is fixedly connected inside the support frame. A wire groove is provided inside the support frame and the cross support.

[0006] The front, left, rear, and right side walls of the supporting frame, as well as the middle part of the cross support, are all detachably connected with movable covers. The partition wall body is configured from the outside to the inside as a supporting outer layer, a sound insulation and heat absorption layer, and a filling inner layer.

[0007] According to the aforementioned precast partition wall panel with a light steel frame and light concrete, the front, rear, left, and right side walls of the partition wall panel body are all sprayed with positioning marks. The positioning marks are aligned with the movable cover. By punching through the positioning marks, the movable cover can be exposed, making it easier for cables to enter the support frame or cross support.

[0008] According to the precast partition wall panel of light steel frame and light concrete, the upper and lower side walls of the connecting flange are fixedly connected with limit plates, and one side of the limit plate is embedded in the outer layer of the support to improve the stability of the connection between the connecting flange and the partition wall panel.

[0009] According to the aforementioned precast partition wall panel with a light steel frame and lightweight concrete, a reinforcing diagonal brace is fixedly connected between the cross support and the interior of the support frame to improve the structural stability between the cross support and the support frame.

[0010] According to the aforementioned precast partition wall panel with a light steel frame and lightweight concrete, the supporting frame and the cross support are both made of light steel materials.

[0011] According to the aforementioned precast partition wall panel with a light steel frame and lightweight concrete, the outer supporting layer is made of concrete.

[0012] According to the aforementioned precast partition wall panel with a light steel frame and lightweight concrete, the sound insulation and heat absorption layer is made of glass wool material.

[0013] According to the aforementioned precast partition wall panel with a light steel frame and lightweight concrete, the inner filling layer is made of foamed concrete material.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with existing technologies, by setting up a detachable movable cover and positioning mark, construction personnel can quickly locate and open the corresponding position for cable laying or maintenance, which greatly improves the flexibility of wiring and the efficiency of later maintenance, and overcomes the defects of traditional pre-buried wire hole positions being fixed and difficult to adjust.

[0016] 2. The design adopts an integrated light steel frame and cross support, with reinforced diagonal bracing to enhance overall stability. The structure is reasonable and has fewer connection nodes, which significantly simplifies the installation process, reduces construction complexity, and improves assembly speed and project quality.

[0025] Reference Figure 1-4 This utility model embodiment provides a prefabricated partition wall panel with a light steel frame and light concrete, which includes a partition wall panel body 1, and the body is provided with a connecting flange 2, a supporting frame 3 and various functional layer structures from top to bottom.

[0026] In practice, the dimensions of the partition wall panel 1 can be customized according to the building module. Common specifications are a height of 2400-3000mm, a width of 600-1200mm, and a thickness of 100-200mm. The connecting flange 2 is embedded in the upper and lower ends of the partition wall panel. It is made of galvanized steel sheet and stamped. Limiting plates are welded to both the upper and lower sides. The limiting plates are embedded in the outer layer 101 concrete of the support to enhance the anchoring strength between the flange and the wall.

[0027] The supporting frame 3 is welded from light steel keel, with a rectangular or square cross section. It has a cross support 301 inside, and the cross intersection is reinforced with diagonal braces 302 by welding or bolting to form a stable spatial truss structure. The supporting frame 3 and the cross support 301 have reserved cable trays 304 inside to facilitate the laying of power cables, communication cables, etc.

[0028] The movable cover 303 is made of plastic or metal and can be detachably installed on each side of the support frame 3 and in the middle of the cross support 301 by means of clips or screws. The partition wall is sprayed with positioning marks 4 around its perimeter, and the marks are aligned with the movable cover 303. During construction, the cover can be opened by drilling or knocking to facilitate the introduction of cables.

[0029] The main body of the partition wall panel 1 consists of, from the outside to the inside, a supporting outer layer 101, a sound insulation and heat absorption layer 103, and an inner filling layer 102. The supporting outer layer 101 is made of C30 lightweight aggregate concrete, with a thickness of approximately 20-30mm, serving both load-bearing and protective functions; the sound insulation and heat absorption layer 103 uses concrete with a density of 40-60kg / m³. 3 The glass wool board is 30-50mm thick and has good sound insulation and heat preservation performance; the inner filling layer 102 is made of foamed concrete with a density grade of A05-A07, which is filled inside the frame to reduce the overall weight and enhance the heat insulation performance.
