Description

Technical Field

[0001] The utility model relates to the technical field of building structure engineering, in particular to a steel-concrete composite floor slab capable of reducing deflection. Background Technique

[0002] With the continuous development of modern building technology, high-rise buildings and large-span structures are increasing day by day, and the requirements for the stiffness and strength of floor slabs are also getting higher and higher. When traditional floor slabs bear heavy loads or have large spans, they are prone to large deflections, affecting the safety and service comfort of buildings. Therefore, it is of great significance to develop a steel-concrete composite floor slab system with lower deflection.

[0003] For example, the patent application with the publication number of CN220267014U in the prior art discloses a partially cast H-shaped steel-concrete composite beam. There is no better protection measure at the connection of the H-shaped steel-concrete composite beam, which will increase its deflection, make the structure unstable, and it is easy to break from the connection when damaged. Therefore, a steel-concrete composite floor slab capable of reducing deflection is needed to solve the above technical problems. Content of the Utility Model

[0004] In view of this, the utility model provides a steel-concrete composite floor slab capable of reducing deflection. Compared with the traditional composite floor slab, the utility model reforms the inside of the I-beam through the reinforcing steel plates and reinforcing bars, and reforms the connection of the I-beam through the reinforcing studs and stirrups, which can further increase the bending resistance and reduce the deflection effect.

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

[0006] A steel-concrete composite floor slab capable of reducing deflection, including an I-beam, reinforcing steel plates, reinforcing bars, reinforcing studs and stirrups. Reinforcing steel plates are respectively installed at both ends of the I-beam, and both ends of the reinforcing steel plates are welded to the upper and lower flange plates of the I-beam. Reinforcing bars are arranged inside the upper and lower flange plates and the reinforcing steel plates. Reinforcing studs are respectively arranged on the upper and lower flange plates at both ends of the I-beam, and stirrups are arranged outside the reinforcing studs.

[0007] Further, the reinforcing bars include transverse reinforcing bars and longitudinal reinforcing bars. Both ends of the transverse reinforcing bars are respectively fixed on the reinforcing steel plates, and both ends of the longitudinal reinforcing bars are respectively fixed on the upper and lower flange plates of the I-beam.

[0008] Further, a plurality of bolt holes are respectively opened at both ends of the web plate of the I-beam, and a plurality of the I-beams are fixedly connected through reinforcing bolts, connecting plates and bolt holes.

[0009] Furthermore, high-strength concrete is poured between the upper and lower flange plates and the web plate of the I-beam, and the outer surface of the high-strength concrete is flush with the edges of the upper and lower flange plates of the I-beam.

[0010] The beneficial effects of the present utility model are as follows:

[0011] The structure of the present utility model is simple and the cost is low. By strengthening the upper and lower flange plates of the I-beam with reinforcing steel plates and reinforcing bars and pouring high-strength concrete, the stiffness and load-bearing capacity of the I-beam can be increased; the connection part of the I-beam is further strengthened by connecting plates, reinforcing bolts, reinforcing studs and stirrups and pouring high-strength concrete. Through the cooperation of the I-beam and the high-strength concrete, the bending resistance and deflection resistance performance can be further increased. BRIEF DESCRIPTION OF THE DRAWINGS

The two ends of the reinforcing steel plate 2 are respectively welded to the upper and lower flange plates of the I-beam 1. The reinforcing steel plate 2 can increase the stiffness of the upper and lower flange plates of the I-beam 1 and reduce the cracking problem. The inner sides of the upper and lower flange plates and the reinforcing steel plate 2 are provided with the reinforcing rib 3, and the reinforcing rib 3 can further improve the deflection resistance performance of the I-beam 1. The upper and lower flange plates at both ends of the I-beam 1 are respectively provided with the reinforcing studs 4, and the stirrups 5 are arranged outside the reinforcing studs 4.

[0022] Preferably, the reinforcing rib 3 includes a transverse reinforcing rib and a longitudinal reinforcing rib. The two ends of the transverse reinforcing rib are respectively fixed on the reinforcing steel plate 2, and the two ends of the longitudinal reinforcing rib are respectively fixed on the upper and lower flange plates of the I-beam 1. The transverse reinforcing rib can effectively improve the local stability of the web and the reinforcing steel plate 2, and the longitudinal reinforcing rib can effectively improve the deflection resistance performance of the upper and lower flange plates of the I-beam 1.

[0023] Preferably, a plurality of bolt holes are respectively opened at both ends of the web plate of the I-beam 1. A plurality of the I-beams 1 are fixedly connected to the connecting plate 6 and the bolt holes through reinforcing bolts, which can effectively prevent cracking at the connection part.
