Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a novel high-density crack-resistant ground structure. Background Technology

[0002] Dampness and cracks on the ground are common problems during construction. Minor issues can cause inconvenience and rework for residents, while major issues can lead to ground subsidence and building collapse. Objectively, dampness and cracks are related to climate and geographical location. In particular, in southern my country, where there is more rain and the climate is more humid in summer, the ground floor of an indoor building often has a layer of condensation before and after rain, causing great inconvenience to daily life. Because the existing conventional ground structure has poor moisture resistance, crack resistance and corrosion resistance, it is prone to damage and thus not suitable for use. Therefore, a new type of high-density crack-resistant ground structure is proposed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2 This utility model provides a technical solution: a novel high-density crack-resistant ground structure, including a base layer 1, a crack-resistant mortar leveling layer 2 laid on top of the base layer 1, the base layer 1 including a first concrete layer 11, a crushed stone layer 12 laid on top of the first concrete layer 11, a second concrete layer 13 laid on top of the crushed stone layer 12, and the crack-resistant mortar leveling layer 2 laid on top of the second concrete layer 13. The thickness of the first concrete layer 11 is 4cm, the thickness of the crushed stone layer 12 is 3cm, and the thickness of the second concrete layer 13 is 2cm. The particle size of the first concrete layer 11 is less than 4mm, the particle size of the crushed stone layer 12 is less than 2mm, and the particle size of the second concrete layer 13 is less than 3mm. By setting the first concrete layer 11, the crushed stone layer 12, and the second concrete layer 13, the density of the base layer 1 is strengthened, and the stability of the bottom of the ground structure is also enhanced.

[0020] A moisture-proof layer 3 is laid on top of the crack-resistant mortar leveling layer 2. The moisture-proof layer 3 is a high-density polyethylene geomembrane with a thickness of 6mm.

[0021] The top of the moisture-proof layer 3 is covered with a first special crack-resistant concrete layer 4, and the top of the first special crack-resistant concrete layer 4 is covered with a crack-resistant metal mesh layer 5. The crack-resistant metal mesh layer 5 is composed of transverse metal wires 51, longitudinal metal wires 52, metal mesh 53 and metal reinforcing mesh 54. The transverse metal wires 51 and longitudinal metal wires 52 are welded perpendicularly to each other to form the metal mesh 53. The metal mesh 53 is welded with metal reinforcing mesh 54 inside. The top of the crack-resistant metal mesh layer 5 is covered with a second special crack-resistant concrete layer 6.

[0022] The first special crack-resistant concrete layer 4 has a thickness of 6 cm, and the second special crack-resistant concrete layer 6 has a thickness of 4 cm. Both the first special crack-resistant concrete layer 4 and the second special crack-resistant concrete layer 6 are made of high-grade cement and the water-cement ratio is reduced to improve the density and strength of the concrete, thereby enhancing its crack resistance. In addition, steel fibers or polypropylene fibers can be added during the preparation of the concrete. These fibers can disperse stress at the microscopic level and effectively prevent the development of micro-cracks, thereby further improving the crack resistance of the concrete.

[0023] The second special crack-resistant concrete layer 6 is topped with an anti-corrosion layer 7, which is an epoxy furan mortar film with a thickness of 5mm. The anti-corrosion layer 7 can block corrosion from the ground and prevent corrosive substances from penetrating the ground, thereby preventing the ground from being corroded as a whole, thus improving the anti-corrosion performance. The anti-corrosion layer 7 is topped with a high crack-resistant cement self-leveling layer 8, which is made of existing crack-resistant self-leveling mortar, so as to make the top of the ground structure flat and beautiful.

[0024] By laying a moisture-proof layer 3 on top of the crack-resistant mortar leveling layer 2, the upward reflection of moisture is reduced, thereby improving the moisture-proof performance of the ground. Secondly, by laying a crack-resistant metal mesh layer 5 between the first special crack-resistant concrete layer 4 and the second special crack-resistant concrete layer 6, the rigidity and stability are enhanced, thereby improving the crack resistance of the ground. Furthermore, by laying an anti-corrosion layer 7 on top of the second special crack-resistant concrete layer 6, the damage to the ground in corrosive environments is reduced, thereby improving the anti-corrosion performance of the ground. Ultimately, this extends the service life of the ground and is beneficial to its use.

[0025] In summary, this novel high-density crack-resistant floor structure improves the floor's moisture resistance by laying a moisture-proof layer 3 on top of the crack-resistant mortar leveling layer 2 to reduce moisture back up. Secondly, it enhances rigidity and stability by laying a crack-resistant metal mesh layer 5 between the first special crack-resistant concrete layer 4 and the second special crack-resistant concrete layer 6, thereby improving the floor's crack resistance. Furthermore, it reduces damage to the floor in corrosive environments by laying an anti-corrosion layer 7 on top of the second special crack-resistant concrete layer 6, thus improving the floor's corrosion resistance and ultimately extending its service life. This solves the problem that existing conventional floor structures often suffer damage due to poor moisture resistance, crack resistance, and corrosion resistance, making them unsuitable for use.
