Floor structure with prefabricated double-curved-arch shells and construction method of floor structure

Abstract

The invention discloses a floor structure with prefabricated double-curved-arch shells. The floor structure is characterized in that the floor structure comprises vertical columns, beams (2), fillinglayers and the prefabricated double-curved-arch shells, the vertical columns and the beams form a frame, the beams are distributed in the transverse direction and the longitudinal direction, every four beams connected end to end form a beam lattice, each beam lattice is internally provided with the corresponding prefabricated double-curved-arch shell, the upper surfaces and the lower surfaces of the prefabricated double-curved-arch shells are each in a double-curved-arch shape, and the edges of each prefabricated double-curved-arch shell are fixedly connected with the side faces of the four corresponding beams correspondingly; and the prefabricated double-curved-arch shells are covered with the filling layers, and the top surfaces of the filling layers are flat. The superior compression performance of concrete is fully utilized, the poor tensile performance of the concrete is avoided, and a large quantity of steel bars and the concrete can be saved; and the prefabricated double-curved-arch shells transmit the load evenly to the frame, so that the frame is structurally stressed evenly, the edges of the prefabricated double-curved-arch shells are fixed through the beam sides of the frame, and thus the bearing capacity of the prefabricated double-curved-arch shells is improved.

Description

technical field [0001] The invention relates to a floor structure with a prefabricated hyperbolic arch shell and a construction method thereof, belonging to the technical field of building structures. Background technique [0002] Two-way frame concrete floors are widely used in housing construction, such as underground parking garages. In order to withstand greater gravity and meet waterproof requirements, the floor form is often used: a reinforced concrete floor is placed on the frame beam to bear the load. When the frame span is 6 to 15 meters, the gravity passes through the bending of the slab The beams are subjected to bending and the main beams are subjected to bending, so more concrete and steel bars are consumed, and the economy of the floor is not good. [0003] The tensile strength of concrete is generally only 1 / 10 to 1 / 20 of the compressive strength, so when designing concrete components, it is always hoped that the concrete components can maximize the compressi...

Problems solved by technology

The disadvantage of the building in Patent Document 1 is that it is essentially a slab-column structure, similar to a large slab floor structure with axillaries, and relies on the bending capacity of the slab to bear the vertical load. This structure does not fully utilize the compressive capacity of the concrete. Large amount of concrete and steel
