Construction method of propeller strut rib plate fabricated double-T plate

Abstract

The invention relates to a construction method of a propeller strut rib plate fabricated double-T plate. The construction method comprises the steps of (1) prefabricating a propeller strut, a wing plate, a lower chord, an end rod and a stabilizer bar in parallel in a prefabrication factory at the same time; (2) transporting prefabricated parts to an assembly site, assembling the propeller strut and the lower chord, and connecting two propeller strut rib plates by adopting the stabilizer bar; (3) flatly laying the wing plate on the propeller strut, putting the upper end of the propeller strut in a hole of the wing plate, and installing a tool steel strand to tension a wing piece of the wing plate; (4) putting a rib body in a chord body of the lower chord, and tensioning the rib body so as to tension the lower chord; (5) hoisting the assembled and integrated propeller strut rib plate fabricated double-T plate to a required position; and (6) determining whether the stabilizer bar is taken off or not according to conditions, and removing the tool steel strand so as to complete installation. According to the construction method of the propeller strut rib plate fabricated double-T plate, split prefabrication and field assembly are adopted, the transportation and storage yard storage are facilitated, the cost is saved, the convenience is improved, the construction period is greatly shortened, economic benefits are brought, wide application prospects are achieved, and the development of fabricated buildings is greatly promoted.

Description

technical field [0001] The invention relates to the technical field of concrete structures in civil engineering, in particular to an assembled double T-slab, in particular to a herringbone rib-assembled double T-slab and a construction method. Background technique [0002] So far, the prefabricated structure has become the development trend of the construction industry, and the production of prefabricated components is its basic component. The double T-plate combines the beam and the plate with its unique structural form, and has a good structure. Performance, fast construction progress, low construction cost, can be made into large-span, large coverage area, relatively economical load-bearing components. The double T plate is composed of a wing plate and two ribs. The wing plate is not only the direct bearing surface of the external load and has the function of a plate, but also the flange of the double T plate when it is used as a T-beam function. The wing plate has the c...

Problems solved by technology

However, engineering practice and theoretical research show that: when the span of the double T-slab is large, the increase of its self-weight is not a linear increase with the increase of the span, but a non-linear increase with the increase of the span, and the project cost is also very high. linear growth

The main reason is that the increase of the height of the ribs is nonlinear, and the increase of the weight of the ribs is also nonlinear. Making the ribs into a truss can certainly solve this problem, but the storage and transportation space required for the overall prefabrication of the truss and the truss Complicated reinforcement and mold costs restrict this idea
