[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to the attached drawings of the specification Figures 1-6, the present utility model provides a manually assembled sandwich panel that prevents cracking, including a manually assembled sandwich panel main body 1. The manually assembled sandwich panel main body 1 includes a magnesium oxychloride core 101. Steel panels 102 are sleeved on both the top and bottom of the magnesium oxychloride core 101. A plurality of hexagonal holes 103 are formed in the top of the magnesium oxychloride core 101. The plurality of hexagonal holes 103 are linearly arrayed on the magnesium oxychloride core 101. The arrangement of the plurality of hexagonal holes 103 makes the magnesium oxychloride core 101 similar to a honeycomb panel, enabling the magnesium oxychloride core 101 to reduce weight while maintaining strength. Moreover, a large number of air compartments are formed within the magnesium oxychloride core 101, effectively blocking heat conduction and having good heat insulation performance. At the same time, the honeycomb panel structure has good energy absorption capacity, capable of absorbing energy when subjected to impact or extrusion, reducing damage and cracking. Additionally, the honeycomb panel structure can effectively absorb sound waves, reducing noise propagation and playing a noise reduction role;

[0028] A plurality of positioning blocks one 2 are fixedly arranged on the top of the steel panel 102 located at the bottom of the magnesium oxychloride core 101. A plurality of positioning blocks two 3 are fixedly arranged on the bottom of the steel panel 102 located at the top of the magnesium oxychloride core 101. The cross-sections of the plurality of positioning blocks one 2 and the plurality of positioning blocks two 3 are both set as hexagons. The plurality of positioning blocks one 2 and the plurality of positioning blocks two 3 are respectively inserted into the plurality of hexagonal holes 103;

[0029] Two insertion rods 4 are fixedly arranged at the top end of each positioning block one 2. Each insertion rod 4 is composed of a hemispherical block 401 and a round rod 402. The hemispherical block 401 is fixed at the top of the round rod 402. Two slots 5 are formed at the bottom end of each positioning block two 3. The slot 5 is composed of a hemispherical groove 501 and a circular hole 502 distributed vertically. The hemispherical block 401 and the round rod 402 are respectively inserted into the hemispherical groove 501 and the circular hole 502;

[0030] Moreover, the diameter of the hemispherical block 401 is greater than the diameter of the round rod 402, and the inner diameter of the hemispherical groove 501 is greater than the inner diameter of the circular hole 502, which is used to improve the firmness between the insertion rod 4 and the slot 5. Wear-resistant coatings are applied on the outer wall surfaces of the two steel panels 102 to improve the wear resistance of the surfaces of the steel panels 102.

[0031] When assembling the manual sandwich panel body 1, the staff first inserts a plurality of hexagonal holes 103 on the magnesium oxychloride core 101 into a plurality of positioning blocks one 2 on the steel panel 102. Then, a plurality of positioning blocks two 3 at the bottom of the other steel panel 102 are aligned with the plurality of hexagonal holes 103 on the magnesium oxychloride core 101 and inserted. Two insertion rods 4 on each positioning block one 2 are inserted into the slots 5 at the bottom of the positioning block two 3. Since the insertion rod 4 is composed of a hemispherical block 401 and a round rod 402, and the diameter of the hemispherical block 401 is larger than that of the round rod 402, when the hemispherical block 401 is inserted into the hemispherical groove 501, it gets stuck with the top of the circular hole 502, which can firmly fix the steel panel 102 and the magnesium oxychloride core board together, avoiding cracking between the steel panel 102 and the magnesium oxychloride core 101, and thus improving the strength of the entire manual sandwich panel body 1.

[0032] Refer to the attached drawings of the specification Figures 1-6 On the surfaces of the two adjacent sides of the two steel panels 102, frame-shaped grooves 6 are respectively opened. A frame-shaped water-swellable water-stop strip 7 is arranged between the two frame-shaped grooves 6. The setting of the frame-shaped water-swellable water-stop strip 7 can improve the sealing and waterproof performance between the two steel panels 102.

[0033] Moreover, a frame-shaped positioning groove 8 is opened at the top end of the steel panel 102 at the bottom of the magnesium oxychloride core 101, and a frame-shaped positioning strip 9 is fixedly arranged at the bottom end of the steel panel 102 at the top of the magnesium oxychloride core 101. The frame-shaped positioning strip 9 is inserted into the frame-shaped positioning groove 8 to assist the staff in fixing the two steel panels 102 together. Polyurethane binder is arranged inside the frame-shaped positioning groove 8, and the frame-shaped positioning strip 9 is fixedly bonded to the frame-shaped positioning groove 8 through the polyurethane binder. The polyurethane binder can improve the connection firmness between the frame-shaped positioning strip 9 and the frame-shaped positioning groove 8.

[0034] After injecting the polyurethane binder into the frame-shaped positioning groove 8 and spreading the polyurethane binder flat, the polyurethane binder can firmly fix the frame-shaped positioning strip 9 and the frame-shaped positioning groove 8 together, further improving the strength of the entire manual sandwich panel body 1. And a frame-shaped water-swellable water-stop strip 7 is arranged between the two steel panels 102. When water seeps into the space between the two steel panels 102, the frame-shaped water-swellable water-stop strip 7 swells when encountering water to form a sealing colloid, which can improve the water-proof performance between the two steel panels 102, and thus can improve the firmness between the two steel panels 102.

[0035] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
