Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a seamless construction structure of an ultra-long concrete structure. Background Art

[0002] In modern building construction, the durability and aesthetics of flooring are crucial. Steel fiber reinforced concrete and corundum flooring are widely used in first-floor floor construction due to their excellent performance. However, during steel fiber floor construction, due to the large overall area of the concrete, the concrete shrinks during the hardening process. When this shrinkage is restrained, tensile stress is generated within the concrete. If the tensile stress exceeds the tensile strength of the concrete, cracks will form on the surface or within the concrete. Large concrete surfaces are more prone to uneven shrinkage during the hardening process, resulting in irregular cracks. Irregular cracks are prone to appearing after construction. These cracks not only affect the aesthetics of the floor but also pose a potential threat to the service life and safety of the floor.

[0003] In traditional construction, post-cast joints are set up to prevent the reinforced concrete structure from shrinking and temperature cracking. Post-cast joints are an effective measure to expand the spacing between expansion joints and eliminate expansion joints. However, because the performance of the combination of new and old concrete is not ideal, under the influence of concrete shrinkage, the cracks are generally penetrating, which not only causes leakage but also affects the protective sealing of the project. Moreover, the formwork and support at the post-cast joints cannot be removed in time, which prolongs the construction period. Utility Model Content

[0004] The purpose of the utility model is to provide a seamless construction structure of an ultra-long concrete structure, so as to solve the problem in the prior art that cracks are easily generated during pouring of the post-casting strip, leading to water seepage.

[0005] To achieve the above-mentioned purpose, the specific technical solution of the seamless construction structure of an ultra-long concrete structure of the present invention is as follows:

[0006] A seamless construction structure for an ultra-long concrete structure, comprising two non-reinforced belts and a self-healing expansion fiber anti-cracking reinforcement belt disposed between the two non-reinforced belts, wherein a connection structure is disposed between the self-healing expansion fiber anti-cracking reinforcement belt and each of the non-reinforced belts; the connection structure comprises two connection mesh components, which are connected by connecting steel bars, and the inner lower ends of the connection mesh components are each provided with a waterstop plate, and the lower end of the bottom connection mesh component is provided with a water retaining block. By providing a self-healing expansion fiber anti-cracking reinforcement belt, cracks caused by shrinkage, temperature changes, etc. during the hardening process of concrete can be effectively prevented, thereby ensuring the integrity and stability of the structure. The provision of a waterstop plate can effectively prevent moisture penetration and improve the waterproof performance of the structure.

[0007] Furthermore, the connection mesh assembly includes a rectangular steel frame composed of narrow and long steel plates. Multiple short transverse steel bars are disposed within the rectangular steel frame, with vertical steel bars positioned above the transverse steel bars. Both the transverse and vertical steel bars are disposed within the rectangular steel frame. The provision of transverse and vertical steel bars increases the tensile and compressive strength of the connection structure, helping to resist shrinkage stress and external loads generated during the concrete hardening process, thereby improving the structure's crack resistance. At the same time, the rectangular steel frame, as the main component of the connection structure, possesses high strength and rigidity, effectively supporting and securing the self-healing expansion fiber anti-cracking reinforcement strips, enhancing the stability of the entire structure.

[0008] Furthermore, an opening is provided in the middle of the narrow steel plate for the transverse reinforcement to pass through, and an opening is provided in the middle of the long steel plate for the vertical reinforcement to pass through. By reserving openings in the narrow and long steel plates, the transverse and vertical reinforcement can be easily passed through, thereby simplifying the installation process and improving construction efficiency.

[0009] Furthermore, the water retaining block is arranged at the inner lower end of the rectangular steel frame composed of the narrow steel plate and the long steel plate, and the end of the water retaining block is tilted upward. The tilted end of the water retaining block can effectively extend the water seepage path, thereby improving the waterproof performance of the structure.

[0010] Furthermore, the water stop plate and the water retaining block are both welded and fixed in the rectangular steel frame. By welding and fixing the water stop plate and the water retaining block in the rectangular steel frame, it is possible to ensure that the connection between these components and the steel frame is more secure, thereby improving the stability of the entire structure.

[0011] Furthermore, the vertical, transverse, and connecting steel bars are all secured to each other by wire or welding. The tight connection between the steel bars effectively disperses stress and prevents cracks. During the concrete hardening process, stress generated by shrinkage, temperature changes, and other factors can be transferred and dispersed through the steel mesh, thereby improving the structure's crack resistance.

[0012] Furthermore, the water retaining block is provided with a middle opening for connecting steel bars to pass through.

[0013] The seamless construction structure of an ultra-long concrete structure provided by the utility model has the following advantages:

[0014] 1. The rectangular steel frame formed by the narrow steel plate and the long steel plate can effectively strengthen the structural strength, effectively strengthen the connection strength between the non-reinforced belt and the self-healing expansion fiber anti-cracking reinforcement belt, and prevent the occurrence of cracks.

[0015] 2. By setting up a self-healing expansion fiber anti-cracking reinforcement belt, cracks caused by shrinkage, temperature changes, etc. in the concrete during the hardening process can be effectively prevented, ensuring the integrity and stability of the structure.

[0016] 3. By setting up two water stop plates, water can be effectively prevented from seeping upwards.

[0017] 4. By setting a water baffle with an upward-curved end on the rectangular steel frame at the lower end, the water seepage path is extended, which can further prevent water from seeping upward.

[0018] 5. The construction is convenient and the overall structure of the device is relatively simple, which effectively reduces the construction period. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The connecting structure 3 is arranged between the non-reinforced belt 1 and the self-healing expansion fiber anti-cracking reinforcement belt 2. The connecting mesh component 31 in the connecting structure 3 is respectively located at the upper and lower ends of the non-reinforced belt 1 and the self-healing expansion fiber anti-cracking reinforcement belt 2.

The middle part of the connection between the non-reinforced belt 1 and the self-healing expansion fiber anti-cracking reinforcement belt 2 is separated by the connecting steel bar 32. Since the two water stop plates 315 are arranged between the two reinforcement belts, the water seeping between the non-reinforced belt 1 and the self-healing expansion fiber anti-cracking reinforcement belt 2 is first blocked by the water stop plate 315 at the upper end. The water in the middle part and the lower end first extends the water flow path at the water retaining block 33, and is then blocked by the water stop plate 315 at the lower end to prevent leakage.

[0027] During construction, the positions of the non-reinforced belt 1 and the self-healing expansion fiber anti-cracking reinforcement belt 2 are first determined, and then the connecting mesh assembly 31 is laid at both ends. When laying the steel bars, the water stop plate 315 is first welded and then the transverse steel bars 314 are laid. The transverse steel bars 314 pass through the narrow steel plate 311.
