Construction method of fragmented integrated double-T plate

Abstract

The invention relates to a fragmented integrated double-T plate and a construction method. The fragmented integrated double-T plate is composed of a rib plate, a wing plate and a tenon key; the rib plate is composed of fins; the tenon key is composed of a connecting piece and a solidification body and located at the joint of the rib piece and the wing piece; the rib piece and the wing piece are connected together, and a shear groove or a connecting piece is reserved in the wing piece. The fins, the fins and the connecting pieces are prefabricated in advance and then assembled and integrated together to form the integral double-T-shaped plate. By the adoption of the fragmented integrated double-T-plate construction method, prefabricated fragmentation and on-site integrated assembly in a factory can be achieved, the storage yard occupied area and the transportation problem of components are greatly reduced, the supply speed of double T-plates is greatly increased, the on-site construction progress is accelerated, the construction period is shortened, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of concrete structures in civil engineering, in particular to a piece-integrated double-T slab, in particular to a construction method for the piece-integrated double-T slab. Background technique [0002] At present, prefabricated buildings have become a form of construction vigorously promoted by the country. The production of prefabricated components is an important construction stage of prefabricated buildings. Among the many prefabricated components, the double T-board will be The combination of beams and slabs has good structural mechanical properties, clear force transmission levels, simple geometric shapes, and rapid construction progress. It is a relatively economical load-bearing component that can be made into a large-span, large-coverage area. 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...

Problems solved by technology

[0003] However, in engineering applications, when the span of the double T plate is large, due to its huge edge size and large space occupation, it must be produced on site due to the limitation of transportation.

There are still thorny problems in the on-site production of double T-boards, that is, the huge outline volume of the integral double-T boards requires a large amount of space for stacking. Many projects cannot meet the stacking requirements because they cannot provide enough space, which affects the progress of the project.

Moreover, even when the length of the double T-plate is small enough to meet the requirements of road transportation, it takes up a large cargo space, resulting in a limited carrying capacity of a vehicle, resulting in an increase in transportation costs and a lag in project progress, which is not conducive to the double-T plate Promotion

In addition, the open-air cast-in-place production of the double T-slab is also affected by typhoons and heavy rains, which also affect the progress of the project

Practice has proved that the traditional construction method of double T-board as a whole is a bottleneck that seriously restricts the construction period. The impact is so great that it often leads to 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
