Description

A prefabricated T-beam reinforcement mold

technical field

The invention relates to the technical field of construction engineering, in particular to a prefabricated T-beam reinforcement mold.

Background technique

T-beam refers to a beam with a T-shaped cross-section, because it is equivalent to digging out the concrete in the tension zone of the rectangular beam that does not play a role in the flexural strength. Although the bending strength of the original rectangle is exactly the same, it can not only save concrete, but also reduce the weight of the component and improve the spanning ability. Traditional prefabricated T-beam reinforcement molds mostly use steel bar binding skeletons to make T-beam reinforcement molds, and then pour concrete. However, this construction method may cause the T-shaped prestressed arch to be too large after tensioning, which will affect the bridge deck. The linear shape has brought many unfavorable factors to the construction of T-beams.

Contents of the invention

The present invention is a kind of prefabricated T-beam reinforcing bar formwork, and its purpose is to provide a kind of prefabricated T-beam in which the upper steel bar cage skeleton and the lower steel cage cage skeleton are formed by the longitudinally stressed steel bars between the T-shaped outer plates and the stirrup anti-shear steel bars Reinforced tires.

In order to achieve the above object, the technical solution of the present invention is: a kind of prefabricated T-beam reinforced tire is composed of cable hole, cable, T-shaped outer plate, upper reinforcement cage skeleton, lower reinforcement cage skeleton, bottom plate, T-shaped upper Composed of beam outer plate and wire hole lower plate; T-shaped outer plate is made of steel plate material, the lower part of the T-shaped outer plate is provided with a wire hole lower plate, and the wire hole lower plate is provided with equidistant cable holes, and the steel plate material is used to make the bottom plate. T-shaped outer plates with lower plates with line holes are arranged at both ends of the T-shaped outer plates, and the upper steel cage skeleton formed by longitudinally stressed steel bars and stirrup shear bars is arranged between the T-shaped outer plates, and longitudinal force is set between the lower plates of line holes. The lower steel cage frame formed by steel bars and stirrup shear steel bars is provided with a threading pipe inside the lower steel cage frame. The pipe is penetrated into the cable, and the fixed formwork is installed on the outer sides of the upper steel cage frame and the lower steel cage frame, and the concrete pouring construction can be carried out.

The beneficial effects of the present invention are: adopting the steel plate material T-shaped outer plate to reinforce both ends can effectively provide the strength of the prefabricated T-beam steel bar, and the T-shaped outer plate connects the longitudinal force-bearing steel bar and the stirrup shear steel bar to form the upper steel bar The tire cage frame and the lower steel cage frame have the advantages of simple support, clear force, convenient construction, material saving, large spanning capacity and no deformation, which can speed up the progress of beam manufacturing and improve the efficiency of steel bar installation and concrete pouring. It is an ideal prefabricated T-beam reinforcement mold for bridge construction.
