Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a plug-in type beam steel bar binding jig. Background Technique
[0002] A beam bridge in which the load-bearing structure is composed of the upper flange of reinforced concrete and the beam rib is called a T-shaped beam bridge, which is named because the cross-section shape of the main beam is like the English letter T. The two protruding parts on both sides of the T-shaped beam are called flanges, and the middle part is called the beam rib (or web); since it is formed by removing the concrete in the tensile zone that has no effect on the bending strength in the rectangular beam, in addition to having the same bending strength as the original rectangular beam, it can not only save concrete, but also reduce the self-weight of the component and improve the spanning ability; the compression zone of the T-shaped beam cross-section uses the pressure-resistant concrete to make the flange plate and also serves as the bridge deck; the tensile zone uses steel bars or prestressed steel bars to bear the tension. As the width of the flange of the T-shaped cross-section increases, the height of the compression zone can be reduced, the internal force couple arm can be increased, and the area of the required tensile steel bars can be reduced.
[0003] At present, during the construction process of T-beams, the internal steel bars of the bridge need to be bound on site, which is time-consuming, laborious and has low efficiency. However, if the binding is carried out simultaneously, the bound steel bars cannot be transported as a whole, resulting in an increase in the construction period.
