[0002] The skip-bin method is suitable for extremely long and large concrete structures, especially large underground garages. Its construction costs are relatively low, making it suitable for most housing and building projects. However, when using the skip-bin method, attention must be paid to the connection of the post-cast joints, subsequent surface curing, and the securing of the joints and waterstops. Protecting the waterproofing steel plates also enhances project quality and longevity.

[0003] For example, the application with publication number CN220035739U discloses a post-casting strip connection structure of a concrete component using a skipping method, which relates to the field of building construction technology. Its specific structure includes: a first casting section; a second casting section; a waterstop steel plate assembly, which is installed between the first casting section and the second casting section; the waterstop steel plate assembly includes: a waterstop plate body; a plurality of waterstop plate wings, which are spaced apart above the waterstop plate body, the waterstop plate wings are bent plates, and the bending directions of two adjacent waterstop plate wings are opposite; the utility model solves the technical problem of a single structure and fixed length of the waterstop steel plate in the prior art.

[0004] However, there are no corresponding protection measures for water-stop steel plates, or waterproof steel plates. During construction, construction machinery operates on a large scale, and the ultra-long concrete components have a large operating surface. Construction is prone to deformation of the steel plates due to carelessness, which is not conducive to the durability of the project. Utility Model Content

[0005] The purpose of this application is to solve the problem that the above-mentioned water-stop steel plate or waterproof steel plate has no corresponding protection measures, the construction machinery has a large operation area during construction, and the ultra-long concrete component has a large operation area. The construction is prone to deformation of the steel plate due to carelessness, which is not conducive to the durability of the project. A post-casting strip connection structure of the ultra-long concrete component skipping method is provided.

[0006] The technical solution adopted in this application is as follows: a post-cast strip connection structure of an ultra-long concrete component using the skipping method, including a post-cast strip, a bottom concrete slab fixedly connected to the outer surface below the post-cast strip, a contact connecting plate fixedly connected to the lower surface of the bottom concrete slab, a side support plate fixedly connected to the outer surface of the side edge of the contact connecting plate, a fixing nail welded on the outer surface of the contact connecting plate next to the side support plate, a fixing groove welded on the outer surface of the contact connecting plate corresponding to the fixing nail, a prefabricated reinforced concrete slab fixedly connected to the lower surface of the contact connecting plate, a water leakage hole provided on the outer surface of the contact connecting plate, and a water outlet hole provided on the outer surface of the side support plate.

A buffer zone is formed above the sealing tape to protect the waterproof steel plate when continuing to construct above, to prevent the waterproof steel plate from being deformed during violent construction, which will reduce the durability of the waterproof steel plate and affect the quality of the project. At the same time, after water penetrates, it enters the prefabricated reinforced concrete slab through the contact connecting plate, serving as a water storage layer, thereby buffering the corrosion progress of the waterproof steel plate and increasing durability.

[0011] By adopting the above technical solution, the bottom plate steel bars are crisscrossed and fixed after being tied with fine steel wires to form a support net, which provides stable support above the waterproof steel plate and ensures the strength of the bottom plate concrete slab.

[0012] In a preferred embodiment, a waterproof steel plate is provided on the lower surface below the contact connection plate, and a sealing tape is fixedly connected to the outer surface of the overlapping portion of the waterproof steel plate.

[0016] In a preferred embodiment, a waterstop is fixedly connected to the lower surface of the waterstop caulking plate, and the waterstop is fixedly connected to supporting steel bars on the outer surfaces of both sides of the waterstop.

[0017] By adopting the above technical solution, the waterstop provides a construction benchmark to ensure the accuracy of construction, and the supporting steel bars provide a skeleton for pouring the compensating concrete slab to ensure the supporting strength of the compensating concrete slab.

[0018] In a preferred embodiment, a concrete cushion layer is fixedly connected to the lower surface of the waterstop, and a compensating concrete slab is provided on the upper surface of the concrete cushion layer.

[0019] By adopting the above technical solution, compensating concrete slabs and concrete cushion layers serve as the foundation function of the post-casting strips in the skip-bin method, and the cast-in-place process at the construction site provides stability and necessity in practice.

The whole is completed in the factory. The connection is completed by fixing nails and fixing grooves, and then the length is extended in conjunction with the sealing tape. A buffer zone is formed above the sealing tape to protect the waterproof steel plate when construction continues above, to prevent deformation of the waterproof steel plate during violent construction, which reduces the durability of the waterproof steel plate and affects the quality of the project. At the same time, after water penetrates, it enters the prefabricated reinforced concrete slab through the contact connecting plate, serving as a water storage layer, thereby buffering the corrosion progress of the waterproof steel plate and increasing durability.

Through installation, most of the water is prevented from continuing to seep and affecting the connecting layer. The support plate 13 provides stable support under the waterproof steel plate 11 to ensure the stability of the overall skeleton of each component.
