Problems solved by technology

[0002] In soft soil areas, due to the consolidation of silt soil caused by a large area of ​​pond filling slag, the ground subsides, and the subsidence of the floor seriously affects the normal use. The treatment methods of composite foundation such as mixing piles and surcharge preloading cannot completely solve the settlement problem. The pile base floor is extremely expensive and the construction is complicated
There is no report on a raised floor that does not need to fill pond slag and uses prestressed composite beams and a composite floor without formwork.

Embodiment Construction

[0026] see Figure 1 to Figure 5 , a heavy-duty superimposed elevated floor 1 provided in the present invention includes piles, prestressed prefabricated beams 2 and composite floor slabs 3, and pretensioned prestressed steel strands 22 are embedded in the prestressed prefabricated beams 2, The prestressed prefabricated beam 2 rests on the pile 1, and the composite floor 3 is composed of closed profiled steel plate 31, steel bar truss 32 and concrete 33. In soft soil areas, the bearing capacity of the foundation is poor. In order to prevent the heavy-duty floor from settling, piles must be driven to bear the load of the floor. The steel strand is used as the main reinforcement, the amount of reinforcement is greatly reduced, and the deflection of the beam is small, and the height of the beam can be reduced. The prestressed prefabricated beam can be placed directly on the pile, or on the pile cap, and can also be placed on the joint if necessary. On the ground beam at the top ...

Abstract

A heavy-load superimposed overhead terrace comprises a pile, prestressed pre-cast beams and a composite floor and is characterized in that pre-tensioning prestressed steel strands are buried in the prestressed pre-cast beams disposed on the pile, and the composite floor is composed of a closed profiled steel sheet, a steel bar truss and a concrete combination. The prestressed overlapped beam is adopted so that steel bar consumption is greatly reduced and pond residue backfilling is omitted. The large-tonnage pile is adopted so that the number of the piles is greatly reduced and total manufacture cost is low.

Description

technical field [0001] The invention relates to the field of building structures, in particular to the raised floor structure and construction in soft soil areas. Background technique [0002] In soft soil areas, due to the consolidation of silt soil caused by a large area of ​​pond filling slag, the ground subsides, and the subsidence of the floor seriously affects the normal use. The treatment methods of composite foundation such as mixing piles and surcharge preloading cannot completely solve the problem of settlement. The pile base floor is expensive and complicated to construct. There is no report on a raised floor that does not need to fill pond slag and adopts prestressed composite beams and a composite floor slab without formwork. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a heavy-duty laminated elevated floor and a construction method ...
