Embodiment Construction

[0039] Such as Figure 2 to Figure 5Shown is a hybrid floor that can reduce its own weight and has good structural rigidity. The floor is a long-span floor with a span of 10m. This floor is also suitable for large-span floors with a span of 7-12m.

[0040] The floor covers include columns 1, column caps 2, concealed beams 3 and multiple square ribbed beams 4. The side length of the densely ribbed beams 4 is 1m. Uniform lattice distribution, the number of column caps 2 is equal to the number of columns 1, each column cap 2 is poured around a corresponding column 1, and the concealed beams 3 are multiple beams arranged in a criss-cross pattern, adjacent to each other A hidden beam 3 is arranged between the vertical columns 1, and every four vertical columns 1 and four hidden beams 3 form a square rigid frame, thereby forming a plurality of uniformly arranged rigid frames, and the four vertical columns 1 are respectively located in the On the four vertices of the square, four hi...

Abstract

The invention discloses a composite floor with a self-weight reducing function and favorable structural stiffness. The composite floor comprises a plurality of upright columns, column caps, hidden beams and a plurality of square dense rib plates, wherein the plurality of upright columns are vertically arranged and are uniformly distributed in a dot matrix way; the hidden beams are a plurality of beams which are horizontally and longitudinally crossed; one of the hidden beams is arranged between every two adjacent upright columns; a square rigid frame is confined by every four upright columns and every four hidden beams; two sides of the hidden beams in each square rigid frame are provided with upper hollow plate strips which are parallel to the hidden beams and are continuously distributed; two ends of the upper hollow plate strips extend to the corresponding column caps; central slabs larger than the dense rib plates in size are arranged in the centers of the rigid frames; and the dense rib plates are located between the central slabs and the upper hollow plate strips. The self-weight of a light floor slab can be reduced by using the composite floor; and the central slabs and the dense rib plates are used for jointly bearing, so that the floor simultaneously has the advantages of a hollow floor and a dense rib floor.

Description

technical field [0001] The invention relates to a floor structure in a building structure, specifically a hybrid floor that can reduce its own weight and has good structural rigidity. The hybrid floor is suitable for office buildings, warehouses, underground garages, large shopping malls, and schools. Large-span buildings such as teaching buildings and libraries. Background technique [0002] The hollow-core floor and the ribbed floor can reduce the height of the structure while realizing large bays. They also have the characteristics of less concrete consumption, light weight of the structure, small earthquake force, and good sound and heat insulation performance of the structure. Saving energy and reducing the cost of construction and use can produce good economic and social benefits. It is the preferred choice for green and environmentally friendly buildings, and it is more and more widely used in practical projects. [0003] The cast-in-place hollow floor is a floor tha...
