Narrow long plane concrete honeycomb type space lattice box type structure and manufacturing method

Abstract

Provided in the present invention is a narrow long plane concrete honeycomb type space lattice box type structure, comprising a large-span narrow long plane concrete honeycomb type hollow sandwich plate floor system and concrete lattice type frame columns; and brackets of a long edge Lx and a span edge Ly of the floor system are rigidly connected to the concrete lattice type frame columns at the periphery to form a multilayer large-span narrow long plane concrete honeycomb type space lattice box type structure system. A mechanical model of the present invention is of a space multilayer box type structure, has excellent three-dimensional space mechanical properties, is uniform in distribution of internal force and high in overall lateral resistant rigidity, correspondingly reduces the use level of steel, saves the use level of building materials, reduces the thickness of the floor system, and meets the building requirements of "safety, rationality, advancement, and economy".

Description

technical field [0001] The invention relates to the technical field of public buildings, more specifically, to a narrow and elongated plane concrete honeycomb space grid box structure and a manufacturing method. Background technique [0002] For public sports buildings, especially stadiums with competition nature, the center of the first floor is the ball game field, and the two sides are about 2,000 seats for spectators. The span length of the competition field should not be less than 34m, that is, the span of the upper floor. There are more than 1,000 seats on each side, and the length is not less than 16m. That is, the rectangular plane of the venue is narrow and long. For example, the width of Ly (span) is about 36m, and the length Lx=about 65m, that is, the ratio of the length Lx of the venue to the span Ly is Lx / Ly >1.5. [0003] In the existing multi-storey and long-span projects, traditional concrete and prestressed concrete frame structure systems are generally ...

Problems solved by technology

[0003] In the existing multi-storey and long-span projects, traditional concrete and prestressed concrete frame structure systems are generally used, which not only requires a large amount of structural materials, but also costs a lot, and the shape of indoor fat beams and columns is extremely unsightly; at the same time, the frame formed by frame beams Under the action of horizontal load (wind and horizontal earthquake) along the span direction, the floor has no three-dimensional space force transmission characteristics, and the space effect of the entire structure is small, that is, the horizontal force along the span direction is borne by frames with equal spacing, but due to The floor of the frame structure belongs to the plane force system, and the gable walls with high lateral stiffness on both sides cannot work together through the floor; furthermore, when the concrete frame of the concrete frame structure has a long span, the beam section is large, such as when Ly=36m , the frame beam cross-sectional size b×h needs to be 800mm×2400mm (h=Ly / 15), when the clear height of each floor of the building is required—that is, the height from the bottom of the beam to the floor is not less than 6m and the total height of the multi-storey building structure does not exceed 24m , the traditional structure can only be made of two layers
