Detailed Description of the Embodiments

[0022] The following further details the present application with reference to the drawings.

[0023] In order to more clearly understand the technical solutions shown in the embodiments of the present application, first, the installation and working principle of the existing precast concrete external wall panels are introduced.

[0024] The existing precast concrete external wall panels are made by mixing aerated concrete with other materials. They have better fire resistance and longer service life, can be mass-produced, and achieve the effect of rapid installation and use, and are recognized by people. However, when the existing concrete precast panels collide or are connected, due to their high hardness, they are prone to cracking during installation and transportation, which in turn leads to the need for rework during the construction process. Moreover, for existing support structures such as support frames, drilling operations are required during connection, which is not suitable for use with relatively thick concrete precast panels, and the strength after installation cannot be guaranteed. Therefore, it is necessary to improve the existing concrete plates and support structures to solve these problems.

[0025] Please refer to Figures 1 to 3 Figures 1 to 3 , a precast concrete exterior wall panel reinforcement device disclosed in an embodiment of the present application, comprising: a support arm 1, a mating side rail 101, mounting holes 2, clamping grooves 3, a wall panel body structure 4, a limiting protrusion 5, threaded holes A6, fastening bolts 7 and filler strips 8. One end of the support arm 1 is bent upward, the mating side rail 101 is arranged at the other end of the support arm 1, the mounting holes 2 are equidistantly and throughly opened on the upwardly bent portion of the support arm 1, the clamping grooves 3 are respectively vertically and throughly opened on the support arm 1, and the support arms 1 are equidistantly arranged on the building surface;

[0026] The wall panel body structure 4 includes a concrete core 41, vertical reinforcing square tubes 42, an outer protective net 43 and a protective plate 44. The appearance of the concrete core 41 is rectangular, the vertical reinforcing square tubes 42 are symmetrically and vertically arranged on both sides inside the concrete core 41, both ends of the vertical reinforcing square tubes 42 respectively extend out of the upper and lower surfaces of the concrete core 41, the outer protective net 43 is fixedly connected to the outer surface of the concrete core 41, and the protective plates 44 are respectively fixedly connected to the front and rear side surfaces of the outer protective net 43;

[0027] The wall panel body structure 4 is cooperatively connected to the upper end of the support arm 1, the vertical reinforcing square tubes 42 are respectively clamped with the clamping grooves 3 on the support arm 1, the limiting protrusion 5 is arranged on the upper surface of the support arm 1 close to the upwardly bent side, the threaded hole A6 is opened in the middle of the upwardly bent portion of the support arm 1, the fastening bolt 7 is threadedly connected to the threaded hole A6, the fastening bolt 7 passes through the middle of the limiting protrusion 5, and the end of the fastening bolt 7 is in contact with the outer surface of the wall panel body structure 4. The filler strip 8 has a T-shaped appearance, the filler strips 8 are respectively arranged in the gaps between the two support arms 1, and the ends of the filler strips 8 are flush with the ends of the support arms 1.

[0028] Specifically, the end of the set support arm 1 is provided with a mounting hole 2, which can be connected to the building surface and is set at equal intervals during construction. This enables two or more support arms 1 to be provided at the lower and upper ends of each wall panel body structure 4. The set clamping groove 3 can cooperate with the vertical reinforcing square pipe 42, improving the installation speed and simplifying the installation steps. The up-and-down docking form can support and position the wall panel body structure 4. The set wall panel body structure 4 adopts a combined structure, and the internal concrete core 41 is made of aerated concrete or a special performance material made by mixing existing concrete with other materials. At least two vertical reinforcing square pipes 42 are symmetrically arranged in each concrete core 41 respectively. The setting of the vertical reinforcing square pipes 42 can improve the firmness of the concrete core 41 after forming, enhance the strength during connection and transportation, and avoid bending and damage. The set outer protection net 43 is made of nylon net or metal net, which can form a restraint on the outer surface of the concrete core 41, thereby improving its crack resistance during production and reducing or avoiding the generation of cracks during transportation. The set protection plate 44 can improve the strength of the front and back sides, and can be painted or laminated during production to form a surface layer with different colors or patterns, ensuring better aesthetics while enhancing the impact resistance. The set limit protrusion 5 can be set according to the thickness of the wall panel body structure 4, being slightly larger than the thickness of the wall panel body structure 4 in terms of distance, improving the adaptability convenience of the wall panel body structure 4. The set fastening bolt 7 passes through the threaded hole A6 and can extend towards the wall panel body structure 4, thereby contacting the protection plate 44 on the inner outer layer thereof to clamp its position, improving the stability after connection. The set filling strip 8 has a horizontal T-shaped appearance and can fill the gap between the support arms 1, completely closing the space between the upper and lower wall panel body structures 4, achieving a more complete protection and insulation effect and a more neat appearance after installation, which is beneficial to improving the aesthetics of the building. The combination of these structures can achieve higher support strength and firmness, being more applicable than existing general-purpose brackets, ensuring higher stability after installation and extending the service life.
