Description

Technical Field

[0001] The utility model particularly relates to a novel prefabricated T-beam capable of improving the hoop effect. Background Art

[0002] Existing prefabricated T-beams include a flange reinforcement frame and a beam rib reinforcement frame. The flange reinforcement frame is manufactured by first bending multiple single-piece separate stirrups into a specific shape. These stirrups are then connected by longitudinal tension reinforcement to form the flange reinforcement frame. Similarly, the beam rib reinforcement frame is also made by tying multiple single-piece separate stirrups with longitudinal tension reinforcement. During construction, the beam rib reinforcement frame is first tied to the frame, the flange reinforcement frame is hoisted into the formwork, and connecting bars are inserted at the connection between the flange reinforcement frame and the beam rib reinforcement frame. After the side formwork is installed, concrete can be poured. However, this traditional prefabricated T-beam has the following problems:

[0003] First, the steel bars need to be cut into single-piece separate stirrups of corresponding lengths. Each single-piece separate stirrup can only be tied with the longitudinal stress-bearing steel bars after bending. The number of bending times is large and the workload is large. Multiple separate single-piece separate stirrups are only tied with the longitudinal stress-bearing steel bars, the integrity of the steel bar skeleton is poor, and the constraint force on the core area concrete of the flange steel bar skeleton and the beam rib steel bar skeleton is low. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a novel prefabricated T-beam that can improve the hoop effect.

[0005] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions:

[0006] A new prefabricated T-beam capable of improving the hoop effect comprises a flange steel bar skeleton, a beam rib steel bar skeleton being vertically arranged on the flange steel bar skeleton, the flange steel bar skeleton comprising flange spiral stirrups and flange longitudinal main bars connected to the flange spiral stirrups, the beam rib steel bar skeleton comprising beam rib spiral stirrups and beam rib longitudinal main bars connected to the beam rib spiral stirrups, the beam rib spiral stirrups and the flange spiral stirrups being both formed by continuously bending a single bar.

[0007] Preferably, the spiral stirrups of the wing panels are arranged to form a wing panel installation space, and all the longitudinal main reinforcements of the wing panels are placed in the wing panel installation space and tied to the spiral stirrups of the wing panels.

[0008] Preferably, the longitudinal cross-section of the wing plate spiral stirrup is a rectangular structure.

[0009] Preferably, the beam-rib spiral stirrups are arranged to form a beam-rib installation space, and all the beam-rib longitudinal main reinforcements are placed in the beam-rib installation space and tied to the beam-rib spiral stirrups.

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

[0011] Compared with the existing technology, the spiral stirrups of the beam rib and the spiral stirrups of the wing plate of the present application are both formed by continuously bending a single steel bar. The spiral stirrups of the beam rib and the longitudinal main bars of the beam rib are tied together to form a beam rib steel bar skeleton, and the spiral stirrups of the wing plate and the longitudinal main bars of the wing plate are tied together to form a wing plate steel bar skeleton. This not only enhances the integrity of the prefabricated T-beam steel bar skeleton and improves the hoop effect of the stirrups on the core area concrete, but also reduces the number of steel bar cuts and bending times from a processing perspective, reduces the workload and improves production efficiency.
