[0029] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an assembled light steel keel composite exterior wall panel, including a wall body 1, which is divided into a front shell 2 and a rear shell 3. A pressure rod 5 and a top rod 6 are arranged on the adjacent sides of the front shell 2 and the rear shell 3. The pressure rod 5 is fixedly connected to the rear shell 3, and the top rod 6 is fixedly connected to the front shell 2. An insertion rod 8 is fixedly connected to the middle of one side of the top rod 6, and the insertion rod 8 is inside the pressure rod 5. A pull rod 7 is fixedly connected to the outer side of the middle of the top surface of the top rod 6, and one end of the pull rod 7 is engaged with the outside of the pressure rod 5. A connecting component is arranged in the middle of the front shell 2 and the rear shell 3.

[0031] When in use, first place the front shell 2 and the rear shell 3 together and bring them close to each other. At this time, the pressure rod 5 will be close to the top rod 6. When the pressure rod 5 and the top rod 6 contact each other, the top of the pull rod 7 will be stuck in the inside of the pressure rod 5 to make the pressure rod 5 and the top rod 6 become one. At this time, the front shell 2 and the rear shell 3 will be fixed together. At the same time, the holes for fixing the keel 4 opened on the front shell 2 and the rear shell 3 can be aligned with each other. At this time, the keel 4 can be placed between the front shell 2 and the rear shell 3, thereby improving the convenience of assembly of the keel 4.

[0032] Reference Figure 2 , Figure 3 and Figure 4 Slide plates 9 are slidably connected to both sides of the top of the insertion rod 8, and blocks 10 are fixedly connected to the far sides of the two side slide plates 9, and a spring 11 is provided between the two side slide plates 9, and the two side blocks 10 are respectively located on both sides of the middle of the pressure rod 5. A card slot 13 is provided in the middle of the bottom surface of the pressure rod 5, and the insertion rod 8 and the two card blocks 10 are located inside the card slot 13. A groove 12 is provided in the middle of the outer wall of the pressure rod 5, and the pull rod 7 is set in an inverted L shape, and one end of the pull rod 7 is located inside the groove 12.

[0033] When the pressure rod 5 and the push rod 6 approach each other, the insertion rod 8 will also enter the interior of the pressure rod 5 at the same time. When the block 10 initially enters the groove 12, the blocks 10 on both sides will be squeezed by the groove 12 and enter the interior of the insertion rod 8. When the insertion rod 8 completely enters the groove 12, the spring 11 will push the blocks 10 on both sides out to make them enter the groove 12. At this time, the stability of the connection between the pressure rod 5 and the push rod 6 can be further improved to avoid mold explosion.

[0034] Reference Figure 2 and Figure 3 The number of pull rods 7 is four, and the four pull rods 7 are evenly distributed on the top surface of the top rod 6, and the pull rods 7 are made of stainless steel.

[0035] By setting four pull rods 7 and setting the pull rods 7 to be made of stainless steel, the elasticity of stainless steel can be utilized. After the pressure rod 5 contacts the top rod 6, the pull rod 7 can be tightly clamped on the outside of the pressure rod 5, thereby improving the stability of the connection between the front shell 2 and the rear shell 3.

[0036] Reference Figure 1 and Figure 2 The connecting assembly includes a keel 4, which is located between the front shell 2 and the rear shell 3, and the middle parts of the front shell 2 and the rear shell 3 are threadedly connected with connecting bolts 17, and the connecting bolts 17 on both sides are threadedly connected to the two sides of the keel 4 respectively.

[0037] The keel 4 can be installed by using bolts, and the keel 4 can be used to support the middle part of the front shell 2 and the rear shell 3, thereby improving the stability of the front shell 2 and the rear shell 3 after assembly.

[0038] Reference Figure 2 , Figure 3 and Figure 4 A rock wool 14 is arranged between the front shell 2 and the rear shell 3, and the keel 4 is in the middle of the rock wool 14. A spray coating 15 is arranged on the outside of the front shell 2 and the rear shell 3, and a reinforcing layer 16 is arranged inside the spray coating 15. The spray coating 15 is set to type II foam concrete or plastering mortar, and the reinforcing layer 16 is set to a light steel mesh mold or a steel mesh material.

[0039] By arranging rock wool 14 between the front shell 2 and the rear shell 3, the rock wool has good sound absorption performance, which can effectively absorb sound wave energy, reduce sound transmission inside and outside the building, and improve the living and working environment. The rock wool also has good high temperature resistance and non-combustibility, which can improve the overall fire protection level of the building and enhance the fire safety of the building. Finally, rock wool has good corrosion resistance and stable chemical properties, and is not easily affected by moisture, mildew or corrosion. Therefore, it can extend the service life of the building and reduce maintenance and repair costs.

[0040] At the same time, the rock wool 14 can also be replaced with organic foam plastic. Organic foam plastic has excellent thermal insulation performance, which can effectively reduce heat conduction, improve the thermal insulation effect of the building, effectively prevent the transfer of indoor and outdoor temperatures, reduce energy consumption, and improve the energy utilization efficiency of the building. Organic foam plastic also has the characteristics of light weight and high strength, and has good bearing capacity and compressive resistance. It can reduce the self-weight of the building, reduce the structural load, and improve the overall structural safety of the building. Organic foam plastic material also has certain sound absorption performance, which can effectively absorb sound wave energy and reduce the propagation of sound. Therefore, it can improve the sound insulation effect of the building and improve indoor comfort. Finally, organic foam plastic has a closed-cell structure and excellent impermeable performance. It can effectively prevent the penetration and absorption of moisture, improve the waterproof and moisture-proof performance of the building, and reduce the possibility of moisture on the exterior wall and mold growth.

[0041] In addition, the rock wool 14 can also be replaced with Type I foam concrete. Since the foam concrete contains bubbles inside, it has good thermal insulation performance and can effectively reduce energy consumption, making it widely used in building insulation and heat preservation. At the same time, Type I foam concrete has low water absorption performance, so it can improve the stability and longevity of the wall in a humid environment.

[0042] When the spray layer 15 uses Type II foam concrete, the Type II foam concrete has the characteristics of high strength and durability, which can improve the structural strength and thus improve the load capacity of the wall. The Type II foam concrete can also be replaced with a plastering mortar, which can improve the overall aesthetics of the wall and protect the base layer. It also helps to disperse the stress on the exterior wall, slow down the cracking and deformation of the exterior wall, and improve the crack resistance of the exterior wall. At the same time, it can also improve the waterproof performance of the building and reduce the possibility of moisture and leakage on the exterior wall.

[0043] By adding a reinforcing layer 16 made of a light steel mesh material to the spray coating 15, the spray coating 15 can have higher compressive and tensile strengths and overall stability, thereby improving the load bearing capacity. The reinforcing layer 16 can also be set as a steel mesh. By utilizing the characteristics of the steel mesh with higher tensile strength and rigidity, the overall structural strength, tensile and compressive resistance and stability of the building can be improved, thereby improving the wind resistance and earthquake resistance of the building.

[0044] When rock wool or type I foam concrete is filled between the front shell 2 and the rear shell 3, the thickness of type II foam concrete or plastering mortar on the outside of the front shell 2 and the rear shell 3 should be no less than 20 mm. When organic foam plastic is filled between the front shell 2 and the rear shell 3, the thickness of type II foam concrete or plastering mortar should be no less than 50 mm.

[0045] Working principle: When in use, first place the front shell 2 and the rear shell 3 together, then move the front shell 2 and the rear shell 3 closer to each other, at this time, the pressure rod 5 can enter between the pull rods 7, and at this time, the insertion rod 8 will also enter the inside of the pressure rod 5 at the same time, when the pressure rod 5 contacts the top rod 6, at this time, the top of the pull rod 7 will be stuck in the groove 12 on the outside of the pressure rod 5, and then the pressure rod 5 and the top rod 6 can be combined into one, at this time, the installation between the front shell 2 and the rear shell 3 can be realized, and at the same time, the holes for fixing the keel 4 opened on the front shell 2 and the rear shell 3 can be aligned with each other, at this time, the keel 4 can be placed between the front shell 2 and the rear shell 3, and finally the front shell 2, the rear shell 3 and the keel 4 are connected together by installing the connecting bolts 17 The keel 4 is assembled and then the concrete can be poured between the front shell 2 and the rear shell 3, and the plug rod 8 will also completely enter the groove 13 at the bottom of the pressure rod 5. When the block 10 initially enters the groove 12, the blocks 10 on both sides will be squeezed by the groove 12 to enter the inside of the plug rod 8. When the plug rod 8 completely enters the inside of the groove 12, the elastic force of the spring 11 will push out the blocks 10 on both sides, and then the blocks 10 on both sides can enter the inside of the groove 12. At this time, the stability of the connection between the pressure rod 5 and the push rod 6 can be further improved, thereby improving the stability of the connection between the front shell 2 and the rear shell 3, and avoiding mold explosion.
