Construction method of assembled double t-plate

Abstract

The invention relates to an assembled double T plate and a construction method, which is composed of a rib plate, a wing plate and tenon keys, the rib plate is composed of ribs, and the wing plate is composed of fins. The mortise key is composed of a connecting piece and a wedge body, and is located at the junction of the rib and the fin, connecting the rib and the fin together, and a shear groove is reserved on the fin. The ribs, fins and connectors are prefabricated in advance, and then assembled into an integral double T-plate. Adopting the prefabricated double T-plate construction method of the invention can realize prefabricated fragmentation in the factory and on-site assembly, which is convenient for storage and transportation, speeds up the construction speed of the double T-plate, reduces the construction period, and has broad application prospects.

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 construction method for the assembled double T-slab. Background technique [0002] At present, prefabricated buildings have become a form of construction vigorously promoted by the country, and the production of prefabricated components is its basic component. The double T-board combines beams and panels into one with its unique structural form, which has excellent Excellent structural performance, fast construction progress, and low construction costs can be made into large-span, large-coverage, and 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 the plate, but also the flange of the double T plate when it is used as the function of the T-beam....

AI Technical Summary

Problems solved by technology

[0003] However, when the span of the double T-plate is large, due to its huge edge size and large space, it is limited by transportation and has to be fabricated on site

There are still problems in the on-site production of double T-boards, that is, the huge space volume of the integral double-T boards occupies a large number of storage yards, and many projects cannot meet the stacking requirements and are difficult to use

Moreover, even when the length of the double T-board is small, it takes up a large cargo space, resulting in limited transport capacity, resulting in an increase in transportation costs and a lag in project progress, which is not conducive to the promotion of double-T boards.

In addition, the open-air cast-in-place production of double T panels was also affected by typhoons, heavy rains, etc., which also affected the progress

Practice has proved that the traditional construction method of double T-board as a whole is a bottleneck that seriously restricts the construction period, often resulting in a multiplied construction period, which does not reflect the advantages of prefabricated buildings.

[0004] Therefore, the existing one-piece prefabricated double T-plate construction method has obvious defects, and new construction methods are needed to improve
