Description

split integrated type double-T plate structure for concrete member

Technical Field

The utility model relates to a concrete structure technical field among the civil engineering, in particular to concrete combination beam plate structure specifically is two T plate structures of burst integrated form.

Background

At present, the assembly type building has become a building form which is widely popularized as a national development strategy, and the prefabricated components are basic constituent elements of the assembly type building and mainly comprise main structure bearing components such as prefabricated floors, prefabricated beams, prefabricated columns, prefabricated walls and prefabricated stairs and auxiliary components such as prefabricated balconies and prefabricated bay windows. The beam and the plate are combined into a whole by the double-T plate in a special structural form, and the double-T plate becomes a unique bright point in the prefabricated member. The bearing component has good structural mechanical property, definite force transmission level and simple geometric shape, and can be manufactured into a large-span, large-coverage-area and relatively economic bearing component. The double-T plate consists of a wide wing plate and two rib plates, wherein the wing plate not only has the function of a plate as a direct bearing surface for external load, but also has the function of a whole bent wing plate of a compression area (the sectional area of the compression area is larger, and a neutral axis approaches or enters the wing plate) when the double-T plate is used as a T-shaped beam. The wing plate has the characteristics of two functions of one material. Therefore, compared with the traditional beam plate system, the double-T plate can save materials and reduce the working procedures.

however, in engineering application, when the span of the double T-shaped plate is large and the double T-shaped plate is transported as a whole component to exceed the limit of road traffic, a method of prefabricating and manufacturing on site is required. The problem that the field manufacture double-T plate is difficult to overcome also exists, the huge volume of integral double-T plate occupies a large amount of places, and a lot of projects can be limited by the places and can not stack the double-T plate, thereby influencing the construction progress and delaying the construction period. And even when the transportation of the whole body is not limited by road traffic, due to the unique structural form of the double T-shaped plates, one plate occupies a large space, so that only a limited number of plates can be transported by one vehicle, unreasonable increase of transportation cost and delay of field construction period are brought, and the use prospect of the double T-shaped plates is influenced. In addition, the field open cast-in-place manufacturing of the double T-shaped plates is influenced by severe weather conditions such as typhoon, heavy rain and the like, and the construction period is delayed. Engineering practice proves that: in the building construction adopting the traditional integral double-T plate, the supply of the double-T plate is a bottleneck which seriously restricts the construction period, and the influence is very large, so that the construction period is often prolonged by more than one time.

therefore, the existing integrated prefabricated double-T plate also has obvious defects and shortcomings, and new technologies are needed to solve the existing problems.
