[0023] The following will be combined with the drawings in the embodiments 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 in 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.
[0024] The utility model provides a high-strength composite concrete column, including a concrete column body 1. In the present application, the concrete column body 1 is cast by ordinary concrete, and a connecting layer 2 is cast on the outer surface of the concrete column body 1 by high-strength concrete. The strength of the concrete column body 1 can be improved by setting the connecting layer 2. The outer surface of the connecting layer 2 is wrapped with a reinforcing layer 3, and the reinforcing layer 3 and the connecting layer 2 are fixed together by concrete. In some embodiments of the present application, the reinforcing layer 3 is a fiber-reinforced composite material. The strength of the concrete column is further improved by setting the reinforcing layer 3, and the outer surface of the reinforcing layer 3 is coated with a waterproof coating, and the outer surface of the connecting layer 2 is sprayed with an immersion coating, which reduces the water absorption of the concrete and keeps the concrete dry, thereby significantly improving the reinforcement protection of the concrete.
[0025] In some embodiments of the present application, the immersion coating is isobutyl triethoxysilane, and the waterproof coating material is SBS modified asphalt waterproof coating.
[0026] A protective layer 4 is provided on the outer surface of the reinforcement layer 3 to protect the reinforcement layer 3. In some embodiments of the present application, the material of the protective layer 4 is high-strength concrete.
[0027] The above-mentioned concrete column body 1 is a segmented structure, including multiple connecting columns 5. One end of the connecting column 5 is provided with a clamp 7, and the other end of the connecting column 5 is provided with a socket 6 adapted to the clamp 7. The clamp 7, the socket 6 and the connecting column 5 are cast together. When the socket 6 and the clamp 7 are cast together by concrete, two adjacent connecting columns 5 can be connected together.
[0028] The interior of the connecting column 5 is inlaid with a steel mesh, which includes a transverse steel ring 9 and a longitudinal steel bar 8. One end of the longitudinal steel bar 8 extends to the outside of the clamp 7, and the other end of the longitudinal steel bar 8 is flush with the end of the clamp 6. By setting the steel mesh, the strength of the concrete column body 1 can be increased.
[0029] In order to avoid mutual influence between adjacent connecting columns 5, the outer surface of the connecting column 5 and the outer surface of the steel mesh in the present application are wrapped with a protective layer 10. The protective layer 10 separates the two adjacent connecting columns 5. In some embodiments of the present application, the material of the protective layer 10 is TPU waterproof film.
[0030] The inner cavity of the holder 6 is stepped, the clamping head 7 is adapted to the inner cavity of the holder 6, the length of the longitudinal steel bar 8 exposed to the outside is the same as the depth of the inner cavity of the holder 6, and the ends of the longitudinal steel bar 8 are in a staggered state, and the distance between the central axes of the two ends of the longitudinal steel bar 8 is the same as the diameter of the longitudinal steel bar 8. With this arrangement, the longitudinal steel bars 8 on the steel mesh in the two adjacent connecting columns 5 can fit tightly, and then it is convenient to tie the longitudinal steel bars 8 in the two adjacent connecting columns 5 together, so that the steel mesh in the concrete column body 1 forms a whole, which is beneficial to improve the strength of the concrete column body 1.
[0031] Concrete is poured into the inner cavity of the clamping seat 6 at the end of the concrete column body, and concrete is poured on the outer surface of the clamping head 7 at the other end of the concrete column, thereby improving the aesthetics of the concrete column body 1.
[0032] To sum up: when the high-strength composite concrete column is in use, the connecting layer 2 and the reinforcing layer 3 can enhance the strength of the composite concrete column and play a waterproof function to keep the concrete column body dry; the provision of the protective layer 10 divides the concrete column body 1 into a plurality of connecting columns 5, avoiding mutual influence between the connecting columns 5 and facilitating the use of the composite concrete column.
