Abstract
The utility model belongs to improvement on hinged support structures of building steel structure supporting wire frames and particular relates to an improved wire frame support base, which comprises a support base bottom board fixedly connected onto an embedded part steel plate, an upright supporting steel pipe fixedly connected at the center of the support base bottom board and a wire frame support base ball fixedly connected onto an upper opening of the supporting steel pipe. The improved wire frame support base is reasonable in structure, easy and convenient to implement, capable of ensuring adhering of a bearing surface and a spherical support base and meeting performance requirements, convenient for batch production, and capable of improving production efficiency and installation accuracy.
Description
Technical field
The utility model belongs to the improvement of construction steel structure grid frame supported pivoting support structure, particularly a kind of improved rack bearing.
Background technology
The space structures that space truss structure is linked through node according to certain grid configuration by many rod members.Have space-load, in light weight, advantage such as rigidity is big, anti-seismic performance is good; Can be used as large span space stress systems such as sports palace, cinema, exhibition hall, Waiting Lounge, stadium, hangar; Pivoting support as grid frame supported; What existing way adopted is that three block plates stand up composition right-angled intersection bearing surface; Support rack ball on the bearing surface, steel plate support face cuts out circular arc according to the rack ball, makes four-bladed vane support face form concave spherical surface.This kind bearing shortcoming is to adopt different steel plate specifications according to different rack ball needs, and steel plate circular arc hand cut is difficult to guarantee cambered surface and the applying of rack ball, and four-bladed vane has four road weld seams; Welding capacity is bigger; Be unfavorable for manufacturing in enormous quantities, reduced production efficiency, also strengthened alignment error.
Summary of the invention
The purpose of the utility model is to provide a kind of improved rack bearing, and it is rational in infrastructure, and is simple and easy to do, can guarantee the applying of support face and tumbler bearing, reaches the performance requirement of rack bearing, is convenient to produce in batches, enhances productivity and installation accuracy.
The purpose of the utility model is achieved in that a kind of improved rack bearing, is included in affixed base-plate on the built-in fitting steel plate, affixed the upright supporting steel pipe in the center of base-plate, affixed rack bearing ball on the mouth of pipe of supporting steel pipe upper end.
Three that bearing is used have circular arc steel plate the utility model and are replaced by corresponding seamless steel pipe fully; The diameter of seamless steel pipe is not less than 108; Wall thickness is not less than 8mm; As long as select corresponding steel pipe just can guarantee the applying of support face and tumbler bearing, it reaches the performance requirement of rack bearing: 1, can carry vertical load; 2, the performance that has anti-vertical pulling force, up-down structure does not disconnect when guaranteeing vertical earthquake; 3, the performance that has horizontal force resistant, structure does not disconnect when guaranteeing horizontal earthquake; 4, can adapt to radially, the displacement request of hoop; 5, can adapt to the corner requirement of any direction; 6, bearing the necking of power do not occur through the sphere power transmission, and the counter-force that acts on upper and lower structure is more even.This bearing is simple and easy to do, can be mass-produced, and has reduced defectives such as welding capacity and support face be not slick and sly, has improved production efficiency, has also improved installation accuracy greatly.
The utility model is rational in infrastructure, and is simple and easy to do, guaranteed the applying of support face and tumbler bearing, reached the performance requirement of rack bearing, is convenient to produce in batches, improved production efficiency, improved installation accuracy.
Description of drawings
To combine accompanying drawing that the utility model is done further to describe below,
Fig. 1 is the main TV structure sketch map of the utility model;
Fig. 2 removes the structural representation of overlooking of rack bearing ball for Fig. 1.
The specific embodiment
A kind of improved rack bearing like Fig. 1, shown in Figure 2, is included in affixed base-plate 2 on the built-in fitting steel plate 1, affixed the upright supporting steel pipe 3 in the center of base-plate 2, affixed rack bearing ball 4 on the supporting steel pipe 3 upper end mouths of pipe.Supporting steel pipe 3 is made up of seamless steel pipe, and the diameter of supporting steel pipe is not less than Φ 108mm, and wall thickness is not less than 8mm.Around supporting steel pipe 3, be uniformly distributed with upright right-angled triangle reinforcing rib 5 is being set, two right-angle sides of reinforcing rib 5 are fixed together with supporting steel pipe 3 and base-plate 2 respectively.
Claims (3)
1. improved rack bearing; Be included in built-in fitting steel plate (1) and go up affixed base-plate (2); It is characterized in that: affixed the upright supporting steel pipe (3) in the center of base-plate (2), affixed rack bearing ball (4) on the mouth of pipe of supporting steel pipe (3) upper end.
2. a kind of improved rack bearing according to claim 1, it is characterized in that: supporting steel pipe (3) is made up of seamless steel pipe, and the diameter of supporting steel pipe is not less than Φ 108mm, and wall thickness is not less than 8mm.
3. a kind of improved rack bearing according to claim 1; It is characterized in that: around supporting steel pipe (3), be uniformly distributed with upright right-angled triangle reinforcing rib (5) is being set, two right-angle sides of reinforcing rib (5) are fixed together with supporting steel pipe (3) and base-plate (2) respectively.
