Description

Technical Field

[0001] The utility model relates to the technical field of concrete structures, in particular to a two-way laminated slab concrete structure. Background Art

[0002] The two-way composite slab is a new type of building structural material composed of two layers of reinforced concrete. Its structural feature is that a layer of steel frame is sandwiched between the upper and lower layers of concrete, which makes it have a stronger bearing capacity. The two-way composite slab has good integrity and a smooth surface, which is convenient for finishing layer decoration. It is suitable for high-rise buildings and large-span buildings that have high requirements for overall rigidity.

[0003] In the current production process of two-way composite slabs, it is usually necessary to first weld a large number of steel bars into a plurality of steel trusses, and then place the steel trusses one by one on the steel mesh surface above the concrete base plate, and then workers use steel wires to wrap the mesh surface and the trusses to limit the position, and finally pour the composite concrete layer to make the two-way composite slab. However, the current two-way composite slabs require the use of a large number of steel frame connectors, resulting in excessive steel consumption and poor economic efficiency. At the same time, during the preparation, the staff are also required to use steel wires to wrap the steel mesh surface and the steel trusses to limit the position, which is more troublesome to operate, which not only increases the workload of the workers, but also reduces the production efficiency of the composite slab. In order to solve the above-mentioned problems, a two-way composite slab concrete structure is provided. Utility Model Content

[0004] The purpose of the utility model is to propose a two-way composite slab concrete structure to solve the problem that a large amount of steel bars are needed in the production process of the current two-way composite slab, which leads to excessively high costs for the enterprise and is more troublesome for workers to operate during preparation, which not only increases the workload of the workers but also reduces the production efficiency of the composite slab.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A two-way composite slab concrete structure is designed, comprising a precast concrete base plate and a composite concrete layer, wherein the composite concrete layer is cast on top of the precast concrete base plate, a steel mesh structure for improving the bearing capacity of the two-way composite slab is arranged on the top of the precast concrete base plate, a plurality of limiting grooves are opened on the top of the precast concrete base plate, a precast connecting plate for further improving the bearing capacity of the two-way composite slab is arranged inside the limiting grooves, a plurality of limiting slots are opened through the surface of the precast connecting plate, and the precast connecting plate is used in conjunction with the steel mesh structure.

[0007] Furthermore, the steel mesh structure includes longitudinal steel bars and transverse steel bars. The number of the longitudinal steel bars is multiple and they are arranged at equal intervals. The number of the transverse steel bars is multiple and they are arranged at equal intervals. The transverse steel bars are fixedly connected to the longitudinal steel bars.

[0008] By adopting the above technical solution and setting longitudinal and transverse steel bars, the longitudinal and transverse bearing capacities of the two-way composite slab concrete structure can be greatly improved, making its bearing capacity stronger, thereby ensuring the safety of the building.

[0009] Furthermore, the limiting slot is of U-shaped design, and the slot width of the limiting slot is greater than the diameter of the transverse steel bar.

[0010] By adopting the above technical solution, through the U-shaped design, the transverse steel bar can fit more closely to the inner wall of the limiting slot, and by making the slot width of the limiting slot slightly larger than the diameter of the transverse steel bar, the transverse steel bar can be quickly inserted into the interior of the limiting slot.

[0011] Furthermore, the number of the limiting slots is the same as the number of the transverse steel bars, and the transverse steel bars are in contact with the top of the inner wall of the limiting slots.

[0012] By adopting the above technical solution, the number of limiting slots is the same as the number of transverse steel bars, which can ensure that each transverse steel bar is correspondingly inserted into the inside of the limiting slot, thereby improving the connection effect between the transverse steel bars and the prefabricated connecting plate.

[0013] Furthermore, the width of the limiting groove is greater than the width of the prefabricated connecting plate, and the prefabricated connecting plate is movably arranged inside the limiting groove.

[0014] By adopting the above technical solution, the width of the limiting groove is slightly larger than the width of the prefabricated connecting plate, which makes it easier for workers to place the prefabricated connecting plate inside the limiting groove, thereby improving operational convenience.

[0015] Furthermore, both sides of the top of the composite concrete layer are fixed with hanging rings in pairs, and the hanging rings on both sides are symmetrically designed.

[0016] By adopting the above technical solution and setting the lifting ring, the bidirectional composite slab concrete structure can be easily hoisted and transported.

[0017] In summary, the present application includes at least one of the following beneficial effects:

[0018] During the production process of the utility model, through the coordinated use of precast concrete base plates, composite concrete layers, steel mesh structures, limit grooves, precast connecting plates and limit card slots, it is convenient for workers to prepare and produce bidirectional composite plates. Compared with the traditional composite plate production process, the process adopted in the present application is more convenient. While ensuring the bearing capacity and overall strength of the composite plates, it can also reduce the use of steel bars, and has good economy, thereby reducing the production cost of the enterprise. Compared with the traditional method in which workers use steel wire to wrap the steel mesh and the steel truss to limit the position, the present application adopts a card connection limit method, which makes it more convenient for workers to operate, which not only reduces the labor workload of workers, but also improves the production efficiency of composite plates.
