Embodiment Construction

[0020]Embodiment of the present invention: when constructing a multi-functional cultural hall with a large span of 3 to 5 floors, the floor is preferably carried out by using the method for making a regular hexagonal steel-concrete combined hollow double grid beam floor of the present invention Make, be about to make the plane shape of floor cover into regular hexagon, adopt hexagonal reinforced concrete frame structure to form six sides of regular hexagon of this regular hexagonal floor, and make the diagonal length L of this regular hexagon ( That is, the span) is 30 meters ≤ L ≤ 48 meters, in the closed regular hexagon formed by the hexagonal reinforced concrete frame, the steel-concrete composite vierendeel beams are respectively arranged along the three directions parallel to the corresponding two sides of the regular hexagon, For example, when L=36m, three steel-concrete composite vierendeel beams are arranged in parallel at equal distances in each direction, so that the ...

Abstract

The invention discloses a right hexagonal steel-concrete combined hollow double lattice floor and a manufacturing method thereof. In the floor, a frame formed by a hexagonal column grid forms the six sides of a floor right hexagon, the length L of the diagonal of the right hexagon is more than or equal to 30 meters and less than or equal to 48 meters, steel-concrete combined hollow beams are connected in the frame of the hexagonal column grid and are parallel to the sides of the hexagon respectively and crossed two by two to form steel-concrete combined hollow beam large right triangular grids with internal three-directional cross, and the structural height of the steel-concrete combined hollow beams is one twentieth or twenty-fourth of the length L of the diagonal; and the inside of each large right triangular grid is provided with three-directionally crossed concentrated ribbed beams which form small right triangular grids, and floor plates are covered on the large and small right triangular grids. The right hexagonal steel-concrete combined hollow double lattice floor has the advantages of good structure integrity, small structural height, small space occupation, concrete, small steel consumption and the like and is particularly suitable for constructing large-span polygonal flat surfaces and multilayer and multifunctional halls.

Description

technical field [0001] The invention relates to a regular hexagonal steel-concrete combined empty-web double-grid beam floor and a manufacturing method thereof, belonging to the technical field of large-span multi-layer reinforced concrete floors. Background technique [0002] The rapid development of my country's economic construction and social-related industries has driven the development of cultural undertakings. There are more and more multi-functional halls for large-scale theatrical performances and activities; It is becoming more and more important. From the plane analysis of the multi-functional (including performance and conference) halls with 600 to 1200 seats, the plane of the regular hexagon is better than the square and rectangular planes. When the diagonal span of the regular hexagon is L=36 meters When the hall area is 842 square meters, about 650 seats can be set; when the diagonal span L=48 meters, the hall area is 1496 square meters, and about 1200 seats can...
