Problems solved by technology

[0003] However, with the development of multi-storey and long-span public buildings, multi-storey and long-span public buildings with circular planes have also appeared. If the floor still adopts the above-mentioned traditional structure, it will not only be subjected to uneven force, but also lead to project cost sharp rise

Embodiment 1

[0037] A circular planar large-span honeycomb concrete hollow sandwich slab floor is provided, which includes an upper chord layer and a lower chord layer with circular edges. A plurality of regular hexagonal grids formed by the jointing of the upper run beams 21 also includes a regular hexagonal upper string plate 22 that is superimposed on the regular hexagonal grids and cast into one body with the regular hexagonal grids.

[0038] Wherein the upper string beam 21 and the lower string beam 11 are vierendeel girders, and each lower string beam is provided with a three-pronged shear key at the junction to enhance the structural strength of the floor.

[0039] Specifically, the setting method of the regular hexagonal grids of the upper and lower chords is as follows: use the upper chord / lower chord to set a central regular hexagonal grid in the center of the upper chord / lower chord, and the periphery of the central hexagonal grid to the upper chord A number of regular hexagonal...

Embodiment 2

[0049] Provide a kind of construction method of described circular plane large-span honeycomb concrete hollow sandwich slab floor, comprising the following steps:

[0050] S1. Connect the lower string beam 11 into several regular hexagonal grids, and the grid edge of the regular hexagonal grid near the edge of the lower string layer intersects with the circular edge of the lower string layer to form a support 3, and the regular hexagonal grid setting method It is: use the lower string beam to set a central regular hexagonal grid in the center of the lower string layer, and a plurality of regular hexagonal grids are radially arranged between the periphery of the central regular hexagonal grid and the circular edge of the lower string layer. The size of the regular hexagonal grid is the same as that of the central regular hexagonal grid, and the radial pattern is as follows: except for the central regular hexagonal grid, for each additional circle of regular hexagonal grids, six ...

Abstract

The invention belongs to the technical field of buildings, and discloses a circular plane large-span honeycomb type concrete open web sandwich plate floor system and a construction method thereof. Thecircular plane large-span honeycomb type concrete open web sandwich plate floor system includes an upper string layer and a lower string layer, the lower string layer includes a plurality of regularhexagon grids connected by lower string beams, and the upper string layer includes a plurality of regular hexagon grids connected by upper string beams, and further includes regular hexagon upper string plates arranged on the regular hexagon grids in a superimposed mode and poured integrally with the regular hexagon grids. According to a arranging mode of the regular hexagon grids, the upper string beams / the lower string beams are used for setting a central regular hexagon grid at the center, and the multiple regular hexagon grids are radially arranged between the periphery of the central regular hexagon grid and the circular edge of the floor system. According to a radiative law, for every additional circle of the regular hexagon grids around the central regular hexagon grid, the six regular hexagon grids are additionally arranged; the regular hexagon grid edges near the edge of the upper string layer / the lower string layer intersect with the circular edge to form supports; and the upper string layer and the lower string layer are connected through a shear connector. According to the floor system, overall stress is reasonable, internal force is evenly distributed, and the projectcost is low.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a circular planar large-span honeycomb concrete hollow sandwich slab floor and a construction method. Background technique [0002] In recent years, the "honeycomb fasting sandwich panel" technology has appeared. Its characteristic is that the fasting grid is a regular hexagon composed of six regular triangle grids, which is similar to a honeycomb. The height is twice the height of the regular triangle, that is, 2h, see the attached figure 1 As shown, it is mainly applied to floors or roofs with rectangular and square-like planes. The surrounding supports are composed of b and 2b in the span direction, and the distance between supports in the long side direction is composed of 2h. The load transfer of the floor is changed from the traditional two-direction orthogonal force transmission to the three-direction floor load with an included angle of 120°, so that the force on the f...
