Description

Technical Field

[0001] This utility model relates to the field of foundation-related technology, specifically a crack-resistant foundation. Background Technology

[0002] The foundation refers to the supporting base under a building, which can bear the load brought by the superstructure and evenly transfer the weight of the building to the soil below, thereby ensuring the stability and safety of the building structure. Moreover, most building foundations are made of steel bars and concrete, and the high strength and good performance of concrete enhance the bearing capacity of the foundation.

[0003] As disclosed in announcement number CN211171905U, a concrete foundation includes a fixed frame, a reinforcing internal mechanism assembled inside the fixed frame, and a filling layer poured inside the fixed frame. The fixed frame, the reinforcing internal mechanism, and the filling layer constitute the main structure of this utility model. The horizontal and vertical frames are reinforced and fixed by L-shaped fixing frames and concave reinforcing members to improve the structural strength of the fixed frame. The reinforcing internal mechanism forms a horizontal reinforcing element by horizontal reinforcing rods and portal-shaped reinforcing rods, and a vertical reinforcing element by vertical reinforcing frames, connecting rods, a third auxiliary reinforcing rod, and a fourth auxiliary reinforcing rod. The vertical reinforcing frame has a honeycomb structure, which utilizes the stability of the triangular structure to improve the strength of the vertical reinforcement. The fifth auxiliary reinforcing member improves the firmness of the connection between adjacent vertical reinforcing frames. The horizontal and vertical reinforcing elements are connected to each other to form a horizontal and vertical reinforcing mesh, which, together with the concrete, has high strength.

[0004] However, in the existing technology, if uneven settlement, over-maintenance, or under-maintenance occurs during long-term use, the exterior of the foundation is prone to cracking. For example, the comparative patents listed above have this problem.

[0005] Therefore, we propose a crack-resistant foundation to solve the above problems. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a crack-resistant foundation, comprising a concrete foundation body, underground piles, and pre-reserved reinforcing bars;

[0008] Also includes:

[0009] The steel reinforcement kit is installed inside the concrete foundation and consists of a main steel reinforcement, multiple steel reinforcement hoops fitted on the outside of the main steel reinforcement, and reinforcing ribs for reinforcement and support.

[0027] 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.

[0028] Please see Figures 1-4 .

[0029] To address the problem of uneven settlement, over- or under-curing of the foundation during long-term use, which can easily lead to external cracking, this solution proposes a crack-resistant foundation. The foundation comprises a concrete base 1, underground piles 2, and pre-reserved reinforcing bars 3. A reinforcing bar assembly 4 is installed inside the concrete base 1. The assembly consists of a main reinforcing bar 5, multiple outer reinforcing bar hoops 6 fitted around the main reinforcing bar 5, and reinforcing bars 7 for reinforcement. A crack-resistant wire mesh 8 is fitted around the outside of the reinforcing bar assembly 4.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, underground piles 2 are installed at the corner of the lower end of the concrete foundation 1. The underground piles 2 are driven into the soil layer, and the upper end of the concrete foundation 1 is provided with reserved steel bars 3. At the same time, the main steel bars 5 are connected to the steel bars inside the concrete foundation 1 and the reserved steel bars 3 respectively, thereby improving the integrity of the foundation. Through the setting of the steel bar kit 4, the outer steel bar hoop 6 is sleeved on the outside of the main steel bar 5 and the outer steel bar hoop 6 is fixed to the main steel bar 5 by tie wire. The outer steel bar hoop 6 is set at equal intervals on the outside of the main steel bar 5, and the reinforcing bars 7 are welded to the middle of the outer steel bar hoop 6. At the same time, the reinforcing bars 7 are set at equal intervals on the inside of the outer steel bar hoop 6, thereby improving the overall strength of the steel bar kit 4. Compared with the traditional hollow steel cage, it has higher strength.

[0031] In addition, such as Figure 4 As shown, the anti-crack wire mesh 8 is fitted on the outside of the steel reinforcement kit 4, and then the concrete body 9 is poured on the inside and outside of the anti-crack wire mesh 8. The anti-crack wire mesh 8 can prevent the foundation from cracking to a certain extent and play a good protective role for the foundation. In addition, a cement leveling layer 10 is set on the outermost side of the foundation, which can make the outer side of the foundation smoother.

[0032] The working principle of this scheme is as follows: The main steel reinforcement 5 and the internal steel reinforcement of the underground pile 2, as well as the reserved steel reinforcement 3, are connected to improve the overall volume integrity. The steel reinforcement kit 4 is composed of the main steel reinforcement 5, the outer steel reinforcement hoop 6, and the reinforcing rib 7. The setting of the reinforcing rib 7 can improve the overall strength of the steel reinforcement kit 4. Moreover, the outer side of the foundation is provided with crack-resistant wire mesh 8. When micro-cracks appear in the foundation due to external loads or internal defects, the mesh structure of the crack-resistant wire mesh 8 can prevent the cracks from extending further and effectively prevent cracking.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
