T-beam concrete pouring construction method

Abstract

The invention relates to a T-beam concrete pouring construction method. The T-beam concrete pouring construction method comprises the following steps that S1, when a hopper starts to perform first-layer concrete pouring on a T-beam from the first end of the T-beam, blanking is stopped when the hopper moves to the position which is a certain distance away from the second end of the T-beam, and first-layer concrete pouring is completed; S2, the hopper in the closed state moves to the second end of the T-beam, blanking is carried out again from the second end of the T-beam, the hopper moves to the first end of the T-beam, and second-layer concrete pouring is carried out; S3, when the hopper in the blanking state moves to the position away from the first end of the T-beam by a certain distance, blanking is stopped again, and concrete pouring of a second layer is completed; S4, the steps S1 to S3 are cycled, and multi-layer concrete pouring is carried out on the T-beam; and S5, when pouring is carried out to the top face of the T-beam, pouring is completed. In the pouring process, excessive cement grout can be prevented from being gathered at the end of the T-beam, the cement grout, gravel and sand can be fully gathered at the end of the T-beam, and the strength of the end of the T-beam is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building pouring, in particular to a construction method for T-beam concrete pouring. Background technique [0002] In the field of construction, a T-beam generally refers to a beam whose cross-sectional form is T-shaped. The protruding part on both sides is called the flange, and the middle part is called the beam rib (or web). 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. [0003] In the existing pouring process, the T-beam concrete is generally poured in layers, using the hopper to drop the material and controlling the movement of the hopper, so that the hopper starts pouring from one end of the T-beam and continues ...

Problems solved by technology

[0004] But the main disadvantage of the pouring sequence of the above-mentioned prior art is that: when the hopper distributes the concrete layers back and forth on the T beam from one end to the other end, it is easy to cause too much cement slurry to collect at the two ends of the T beam. As a result, the cement slurry is easy to flow out from the formwork gap at the end of the T-beam, and the gravel and sand at the end of the T-beam cannot fully converge with the cement slurry, resulting in the risk of pitting the concrete, which in turn causes the end of the T-beam to be special. The strength of the concrete at the embedded slab of the support drops significantly
