High-pile wharf longitudinal and transverse beam total prefabrication design construction method

Abstract

The invention discloses a high-pile wharf longitudinal and transverse beam total prefabrication design construction method. The high-pile wharf longitudinal and transverse beam total prefabrication design construction method comprises the steps that firstly, after pile cap construction, top-layer steel bars of a to-be-installed longitudinal and transverse beam are cut off, and a waist rib plate ofthe longitudinal and transverse beam is bent to 90 degrees; secondly, the longitudinal and transverse beam and a prefabricated plate are erected; thirdly, the waist rib plate of the longitudinal andtransverse beam is straightened, and a wire binding device is used for sequentially binding bottom-layer steel bars and waist ribs of the longitudinal and transverse beam from bottom to top; fourthly,reinforcing steel bars are arranged on a cast-in-place layer over the top-layer steel bars and are parallel to the top-layer steel bars; fifthly, the reinforcing steel bars and the steel bars of thecast-in-place layer are synchronously subjected to binding, and a side die of the cast-in-place layer is installed; and sixthly, concrete pouring is conducted on longitudinal and transverse beam joints, plate seams and the cast-in-place face layer, and surface finishing construction is conducted after curing. The method that the prefabricated transverse beam top-layer steel bars are removed, and reinforcing is conducted on the cast-in-place layer is adopted, rapid installation of the wharf prefabricated longitudinal and transverse beam can be achieved, and the stability of prefabricated longitudinal and transverse beam installation is guaranteed while the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of wharf structure design and construction. More specifically, the present invention relates to a fully prefabricated design and construction method for longitudinal and horizontal beams of high-pile wharfs. Background technique [0002] In wharf construction, a major trend is to increase the volume of prefabricated structures as much as possible. Prefabricated structure construction has the advantages of safer, high quality, fast speed, low cost, and less environmental pollution. It can be carried out simultaneously with the pier foundation construction, thereby reducing the construction period of the wharf superstructure after the pile foundation is completed. However, the traditional design and construction generally adopts the process of prefabricating longitudinal beams and casting in-situ beams to ensure easy installation at the joints of longitudinal and beams; Difficult to meet the increasingly tight project...

Problems solved by technology

However, the traditional design and construction generally adopts the process of prefabricating longitudinal beams and casting in-situ beams to ensure easy installation at the joints of longitudinal and beams; It is difficult to meet the increasingly tight project schedule requirements

[0003] In order to solve the above problems, when the full prefabrication design method of longitudinal and horizontal beams is adopted, welding connection of the steel bars at the joints can be considered, but the welding work is relatively large, and the procedures are relatively cumbersome, the construction progress is slow, and the cost is high; if binding design, steel bars need to be straightened after plate bending, although the construction speed is faster, but it is difficult to plate bend the thicker main bars on the top layer of prefabricated beams
