Problems solved by technology

The former has high lateral rigidity, but poor seismic performance, and the number of rods is extremely large, and the on-site installation workload is large. In addition, the support on all sides is not conducive to the lifting and installation of mechanical equipment in the garage from the side, which will definitely prolong the construction period. , not conducive to installation and construction in bustling and crowded cities
The unsupported pure frame garage load-bearing frame has greater ductility and seismic performance, but the lateral stiffness is small, the lateral displacement is large, the second-order effect is significant, and it is easy to cause damage to non-structural components, and excessive lateral deformation is easy Cause the lifting and traversing mechanism to lose the stable working environment and cause operation failure

Embodiment

[0016] In this embodiment, the vertical lifting type high-rise steel structure three-dimensional car load-bearing structure has a horizontal length S of 6 meters, a longitudinal length L of 7.8 meters, and a floor height h of 2.2 meters. ) frame beam 3, the X-shaped support 4 arranged between the front and rear facade central columns, the middle transverse (y-direction) frame beam 5 and the energy-dissipating trusses 6 on both sides, forming the middle lifting shaft I and the parking spaces on both sides II. The energy-dissipating trusses 6 arranged in the facade compartments on both sides of the structure constitute the anti-side member for the structure to bear the in-plane horizontal force.

[0017] The energy-dissipating truss 6 of this embodiment is composed of an upper chord 7, a lower chord 8, two oblique webs 9 and two vertical webs 10. All the webs are symmetrically arranged, and the height of the truss is the same as the height of the structure. The truss and the str...

Abstract

The invention discloses a bearing structure of a three-dimensional garage with an energy-consumption truss lateral-resistance form vertical-lifting type high-rise steel structure. A lateral-resistance component of horizontal force in the bearing faces of upright faces at both sides of the structure of the three-dimensional garage comprises energy-consumption trusses arranged layer by layer. Each energy-consumption truss comprises an upper chord member, a lower chord member, two upright web members and two diagonal web members, wherein all the web members are symmetrically arranged, the heightof the trusses is the same as the height of a structural layer, and the trusses are leveled with the structural layer; the upper chord member and the lower chord member are both continuous chord members, and both ends of each continuous chord member are rigidly connected with corner posts; the two upright web members are vertical to the upper chord member and the lower chord member, both ends of each vertical web member are respectively hinged with the upper chord member and the lower chord member, and the distance of the two upright web members is 1 / 8 to 1 / 4 times the height of the trusses; one end of each diagonal web member is hinged at the position of the connecting joint of the upper chord member and the corner posts, and the other end of each diagonal web member is slantways hinged at the position of the connecting joint of the upright web members and the lower chord member downwards; and thereby, a shearing energy-consumption section the length of which is 1 / 8 to 1 / 4 times of the height of the trusses is formed at the middle parts of the upper chord member and the lower chord member of the energy-consumption trusses. By the invention, the structure has better shock resistant performance and sufficient lateral-resistance rigidity; and meanwhile, by the interlayer arrangement of the trusses, mechanical equipment in the garage is convenient to hang and install laterally.

Description

technical field [0001] The invention relates to an urban parking lot, in particular to a load-bearing structure of a vertical lift-type high-rise steel structure three-dimensional garage for parking small cars in the city. Background technique [0002] Along with the rapid development of my country's economy and the rapid development of the automobile industry, the penetration rate of family cars in cities has increased rapidly. Since the construction of parking lots in cities cannot keep up with the growth of the number of cars, the contradiction of parking vehicles in cities has become increasingly acute. Due to the high-rise steel structure three-dimensional parking garage has the characteristics of small footprint, high car capacity, convenient construction, short time required for car storage and storage, and safe car storage, it has become the first choice for solving parking problems in large and medium-sized cities in my country. The vertical lift type high-rise thr...
