Description

Technical Field

[0001] This utility model relates to the field of sandwich panel technology, specifically to a prefabricated concrete sandwich panel. Background Technology

[0002] As the modern construction industry continues to move towards industrialization, efficiency, and environmental protection, traditional on-site concrete pouring construction methods are gradually facing numerous challenges. Building industrialization emphasizes standardized design of building components, factory production, prefabricated construction, and integrated decoration to improve building quality, shorten construction period, and reduce resource consumption and environmental pollution. Against this backdrop, prefabricated building structure systems have emerged and been widely used. Among them, prefabricated concrete sandwich panels, as a new type of building envelope material, have significant advantages and broad application prospects. However, existing concrete sandwich panels have poor rigidity during use and are prone to breakage and damage under external forces. They are also easily bumped during handling and assembly, leading to edge and corner cracks. In addition, traditional concrete sandwich panels are only fixed with bolts during assembly, and the joints are prone to detachment and breakage when subjected to excessive loads or stresses. To solve the above problems, a prefabricated concrete sandwich panel is needed.

[0003] Existing concrete sandwich panels suffer from problems such as poor stability at assembly joints, poor overall rigidity, and inability to provide impact protection for the edges and corners during operation. Therefore, there is an urgent need for a prefabricated concrete sandwich panel. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a prefabricated concrete sandwich panel to solve the problems of poor stability at the assembly connection, poor overall rigidity of the concrete sandwich panel, and inability to protect the edges and corners of the concrete sandwich panel from impact when using existing concrete sandwich panels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated concrete sandwich panel, comprising a sandwich panel body, reinforcing ribs installed on the inner wall of the sandwich panel body, anti-collision corner guards installed on the outer wall of the sandwich panel body, a limiting groove formed on the inner wall of the sandwich panel body, a connecting sleeve installed on the outer wall of the sandwich panel body, a clamping plate installed on the outer wall of the connecting sleeve, a fixing rod penetrating through the interior of the connecting sleeve, and a fixing sleeve installed on the outer wall of the fixing rod.

[0006] Preferably, the reinforcing ribs are pre-embedded and connected to the sandwich panel body, and the reinforcing ribs are evenly distributed with the central axis of the sandwich panel body as the center.

[0007] Preferably, the anti-collision corner guards are symmetrically arranged around the central axis of the sandwich panel body, and the anti-collision corner guards are bonded to the sandwich panel body.

[0008] Preferably, the connecting sleeve engages with the sandwich panel body, and the connecting sleeve is I-shaped.

[0009] Preferably, the clamping plate is tightly fitted to the surface of the sandwich panel body, and the clamping plate is symmetrically arranged with the central axis of the connecting sleeve as the center.

[0010] Preferably, the fixing rod passes through the interior of the connecting sleeve and the sandwich panel body and is threadedly connected to the fixing sleeve, and the fixing rods are evenly distributed around the central axis of the connecting sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting reinforcing ribs, this utility model can enhance the bending resistance of sandwich panels when the main body is large and the length or height exceeds a certain range, and large deformation is likely to occur under its own weight and external load. This can prevent large deformation from affecting the use.

[0013] 2. The anti-collision corner guards of this utility model can prevent corner breakage during the handling or assembly of sandwich panels. These breakages can damage the integrity of the cross-section. When subjected to forces such as the weight of the wall or the load from the upper structure, the corners, which were originally able to share some of the pressure, will have reduced load-bearing capacity after breakage. When used as an enclosure structure and bearing part of the wind load, damage to the corners may reduce its ability to resist wind suction and lateral pressure, thus reducing the safety reserve of the entire wall structure. The anti-collision corner guards can prevent corner breakage and improve the safety of handling or assembling sandwich panels.

[0014] 3. This utility model uses a limiting groove, connecting sleeve, clamping plate, fixing rod, and fixing sleeve to engage and connect the sandwich panel body to both sides of the connecting sleeve. After moving the sandwich panel body to a suitable position, the fixing rod passes through the interior of the sandwich panel body and the connecting sleeve and is threadedly connected to the fixing sleeve. The connecting sleeve allows for quick assembly of the sandwich panel body, shortening the construction period, while the clamping plate increases the stability and rigidity of the connection between the connecting sleeve and the sandwich panel body, preventing breakage and detachment.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1-4 A prefabricated concrete sandwich panel includes a sandwich panel body 1. Reinforcing ribs 2 are installed on the inner wall of the sandwich panel body 1. The reinforcing ribs 2 are pre-embedded and connected to the sandwich panel body 1. The reinforcing ribs 2 are evenly distributed around the central axis of the sandwich panel body 1. With the reinforcement ribs 2, when the size of the sandwich panel body 1 is large and the length or height exceeds a certain range, it is easy to generate large deformation under its own weight and external load. The reinforcement ribs 2 can enhance the bending resistance and avoid large deformation that would affect the use.

[0023] Please see Figure 1-4 A prefabricated concrete sandwich panel is provided, wherein anti-collision corner guards 3 are installed on the outer wall of the main body 1 of the sandwich panel. The anti-collision corner guards 3 are symmetrically arranged around the central axis of the main body 1 of the sandwich panel and are bonded to the main body 1 of the sandwich panel. Through the installation of anti-collision corner guards 3, the main body 1 of the sandwich panel may be subjected to external impact during handling or assembly, resulting in the corners breaking and the integrity of its cross-section being damaged. When bearing forces such as the self-weight of the wall and the load transmitted from the upper structure, the corners, which originally could share a certain amount of pressure, have reduced load-bearing capacity after breaking. When used as an enclosure structure and bearing part of the wind load, the damage to the corners may reduce its ability to resist wind suction and lateral pressure, thus reducing the safety reserve of the entire wall structure. The installation of anti-collision corner guards 3 can prevent the corners from breaking and improve the safety of handling or assembling the main body 1 of the sandwich panel.

[0024] Please see Figure 1-4A prefabricated concrete sandwich panel includes a limiting groove 4 on the inner wall of the main body 1, a connecting sleeve 5 installed on the outer wall of the main body 1, a clamping plate 6 installed on the outer wall of the connecting sleeve 5, a fixing rod 7 penetrating the interior of the connecting sleeve 5, and a fixing sleeve 8 installed on the outer wall of the fixing rod 7. The connecting sleeve 5 is I-shaped and engages with the main body 1. The clamping plate 6 is tightly fitted to the surface of the main body 1 and is symmetrically arranged around the central axis of the connecting sleeve 5. The fixing rod 7 is threaded through the interior of the connecting sleeve 5 and the main body 1 and is threadedly connected to the fixing sleeve 8. The fixing rods 7 are evenly distributed around the central axis of the connecting sleeve 5. Through the limiting groove 4, connecting sleeve 5, clamping plate 6, fixing rods 7 and fixing sleeve 8, the sandwich panel body 1 is respectively engaged and connected to both sides of the connecting sleeve 5. After the sandwich panel body 1 is moved to a suitable position, the fixing rods 7 pass through the interior of the sandwich panel body 1 and the connecting sleeve 5 and are threadedly connected to the fixing sleeve 8. The setting of the connecting sleeve 5 can enable the sandwich panel body 1 to be assembled quickly and shorten the construction period, while the setting of the clamping plate 6 can increase the stability and rigidity of the connection between the connecting sleeve 5 and the sandwich panel body 1 and prevent breakage and detachment.

[0025] Working Principle: In use, first move the device to the desired position, then engage the sandwich panel body 1 with both sides of the connecting sleeve 5. After moving the sandwich panel body 1 to the appropriate position, insert the fixing rod 7 through the interior of the sandwich panel body 1 and the connecting sleeve 5, and thread it onto the fixing sleeve 8. The connecting sleeve 5 allows for quick assembly of the sandwich panel body 1, shortening the construction period. The clamping plate 6 increases the stability and rigidity of the connection between the connecting sleeve 5 and the sandwich panel body 1, preventing breakage and detachment. When the size of the sandwich panel body 1 is large, with its length or height exceeding a certain range, it is prone to significant deformation under its own weight and external loads. The reinforcing rib 2 enhances its bending resistance, preventing significant deformation and thus affecting its performance. During use, the sandwich panel body 1 may be subjected to external impacts during handling or assembly, causing the corners to crack and the cross-sectional integrity to be damaged. When subjected to forces such as the self-weight of the wall and the load from the upper structure, the corners, which were originally able to share some of the pressure, will have reduced load-bearing capacity after cracking. When used as an enclosure structure and bearing part of the wind load, the damage to the corners may reduce its ability to resist wind suction and lateral pressure, thus reducing the safety reserve of the entire wall structure. The anti-collision corner guards 3 can prevent the corners from cracking and improve the safety of handling or assembly of the sandwich panel body 1. This completes the use of the device. The contents not described in detail in this specification are known prior art to those skilled in the art.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
