[0002] In modern buildings, basement engineering is a very critical link in construction. Among them, basement floor cracking is a problem that the engineering industry has not been able to completely solve from the beginning to now. In particular, the driving area is more affected by long-term vehicle rolling on the floor.

[0003] Combining existing technologies, we found that:

[0004] Existing basement driving areas are generally paved with concrete to provide a solid driving surface. To enhance its crack resistance, methods such as controlling the concrete mix ratio and adding fiber reinforcements are usually adopted. However, since basement driving areas are affected by various factors such as foundation settlement and temperature changes, the occurrence of cracks is still difficult to completely avoid.

[0008] In some embodiments, elastic silicone structural adhesive is filled between the hydrophobic layer and the floor.

[0009] In some embodiments, the seams between the hydrophobic layer and the mounting plate are filled with waterproof glue.

[0010] In some embodiments, a limiting plate is fixed at a middle position on the upper side of the mounting plate, and the limiting plate is fixedly connected to the sliding rod.

[0011] In certain embodiments, the pier is cast from concrete with a reinforcing agent added.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0022] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides an improved anti-cracking structure for a basement vehicle area. The technical solution of the utility model is:

[0024] Example 1:

[0025] like Figure 1-Figure 2 As shown, an anti-cracking structure of a basement vehicle driving area includes a structural bottom plate 1, a hydrophobic layer 2 is provided on the upper side of the structural bottom plate 1, a floor 3 is provided above the hydrophobic layer 2, a plurality of longitudinal reinforcements 4 are pre-embedded on the inner side of the hydrophobic layer 2, a plurality of stirrups 5 are tied around the outer sides of the plurality of longitudinal reinforcements 4, column piers 6 are provided on the inner sides of the plurality of longitudinal reinforcements 4 and stirrups 5, and further includes: a telescopic component; by providing a plurality of longitudinal reinforcements 4 and stirrups 5, the bearing capacity and stability of the foundation are enhanced, thereby improving the anti-cracking effect.

[0026] like Figure 2 As shown, in one embodiment, the column pier 6 is specifically cast by concrete with a reinforcing agent added, which further enhances the crack resistance.

[0027] Example 2:

[0028] like Figure 3 As shown, in the second embodiment, the telescopic assembly includes a mounting plate 7 fixedly connected to the inner side of the hydrophobic layer 2 by embedded bolts, a fixed block 8 fixed to the lower side of the floor 3, the mounting plate 7 fits in place with the upper side of the pier 6, two fixed plates 9 are symmetrically fixed to the upper side of the mounting plate 7, a sliding rod 10 is fixedly connected between the two fixed plates 9, the outer side of the sliding rod 10 is symmetrically slidably connected to two moving blocks 11, the inner sides of the two moving blocks 11 are rotatably connected to rotating arms 13, the other ends of the two rotating arms 13 are rotatably connected to the inner side of the fixed block 8, the outer side of the sliding rod 10 is symmetrically slidably connected to two fixing rings 101, the two fixing rings 101 are respectively fixedly connected to the two moving blocks 11, the outer side of the sliding rod 10 is symmetrically sleeved with two springs 12, one end of the two springs 12 is respectively fixed to one side of the two fixing rings 101, and the other ends of the two springs 12 are respectively fixed to one side of the two fixing plates 9;

[0029] Combined with the description of the above telescopic components, when the temperature changes or the foundation settlement causes deformation, the floor 3 sinks, which produces a certain amount of squeezing on the elastic silicone structural adhesive 14. At the same time, the fixed block 8 moves downward, driving the two rotating arms 13 to rotate the rod and slide along the outside of the sliding rod 10, squeezing the two springs 12. The elastic potential energy of the two springs 12 can be used to effectively reduce deformation, thereby further improving the anti-deformation and anti-cracking effect.

[0030] like Figure 2 As shown, in the second embodiment, elastic silicone structural adhesive 14 is filled between the hydrophobic layer 2 and the floor 3 to ensure the feasibility of expansion and contraction resistance.

[0031] like Figure 2 As shown, in the second embodiment, the joints between the hydrophobic layer 2 and the mounting plate 7 are filled with waterproof glue to achieve waterproof and leakage-proof effects.

[0032] like Figure 3 As shown, in the second embodiment, a limit plate 15 is fixed at the middle position of the upper side of the mounting plate 7 , and the limit plate 15 is fixedly connected to the slide rod 10 .

[0033] The specific working method is: during construction, multiple longitudinal bars 4 are pre-buried in the vehicle area, and stirrups 5 are tied on the outside of the multiple longitudinal bars 4. At the same time, when the hydrophobic layer 2 is constructed, the position of the pier 6 is reserved, and the pier 6 is formed by pouring concrete with fiber reinforcement. By providing multiple longitudinal bars 4 and stirrups 5, the bearing capacity and stability of the foundation are enhanced, and the anti-cracking effect is improved. In order to cope with the deformation and stress concentration caused by temperature changes and foundation settlement, a telescopic structure is provided between the hydrophobic layer 2 and the floor 3. At the same time, elastic silicone structural adhesive 14 is filled between the hydrophobic layer 2 and the floor 3 to ensure the feasibility of telescopic expansion. When the temperature changes or the foundation settlement causes deformation, the floor 3 sinks, which produces a certain amount of extrusion on the elastic silicone structural adhesive 14. At the same time, the fixed block 8 moves down, driving the two rotating arms 13 to rotate the rod, and slide along the outside of the sliding rod 10, squeezing the two springs 12. The elastic potential energy of the two springs 12 can effectively reduce deformation, thereby further improving the anti-deformation and anti-cracking effect.

Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
