Description

The rack bearing
Technical field
The utility model belongs to the space truss structure technical field of buildings, is specifically related to a kind of rack bearing.
Background technology
The rack neoprene bearing not only can make structural bearings obtain enough bearing capacities under the situation that excessive vertical compressive strain do not occur, and the rubber mat plate better elastic also can produce bigger shear strain, therefore rotation requirement that both can adaptive mess structural bearings node, can adapt to the bearing node again because the horizontal movement that variation of temperature and geological process produce, and the material good and economic, therefore the rack for large span generally all adopts neoprene bearing to discharge bigger counter-force.But, for the bigger structure of horizontal force, even considered the elastic stiffness of neoprene bearing, its horizontal force still is considerable, this horizontal force have to be born by the lower support structure, has improved material and performance demands to the lower support structure, thereby has influenced the economy of lower support structure, even the release that horizontal force can the occur phenomenon that causes substructure to be destroyed, have influence on the safety of structure.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of rack bearing that can move in limited field, make structure can consider that the elastic stiffness of neoprene bearing can move again within the specific limits, the rack bearing horizontal force that solves the large span grid structure bears excessive and economy and safety issue that cause.
The utility model is achieved by the following technical solution: a kind of rack bearing comprises a seat body of mainly being made up of bearing ball, bearing gusset and base-plate, and mainly installs and fixes assembly by what pre-embedded steel slab, crab-bolt and nut were formed; Described bearing ball bottom is fixedly connected on the described base-plate by a plurality of described bearing gussets, through hole is arranged on the base-plate, described crab-bolt is vertically passed described through hole and described pre-embedded steel slab, the bottom of crab-bolt is fixed in the lower support structure, the top of described crab-bolt is connected on the described base-plate by described nut, crab-bolt and described pre-embedded steel slab weld together, described pre-embedded steel slab is fixed on the upper surface of described lower support structure, and the bottom of pre-embedded steel slab is fixed with shear key; Be provided with rubber pad between described pre-embedded steel slab and the described base-plate, the through hole that passes for described crab-bolt is arranged on the rubber pad, the bearing baffle plate is arranged on the described pre-embedded steel slab, leave apart from a between the side of bearing baffle plate and adjacent base-plate, the radius of described through hole is not less than the radius sum apart from a and described crab-bolt, between described through hole and the described nut nut cushion block is housed, the diameter of nut cushion block cross section or inscribed circle diameter have the through hole that passes for described crab-bolt greater than the diameter of through hole on the described nut cushion block.
Between described bearing baffle plate and the described pre-embedded steel slab a plurality of gussets are arranged, the height of gusset is not more than the height of described rubber pad.
The periphery of described rubber pad is provided with the rubber stop block.
The beneficial effects of the utility model are:
1, strengthened the through hole on the base-plate, bearing has had mobile space, can consider that the elastic stiffness of neoprene bearing can move again within the specific limits, thereby the horizontal force that bearing is born obtains bigger buffering and release, has increased safety.
2, the buffering of horizontal force and release can make the economy of lower support structure greatly increase, and have reduced the total cost of engineering.
3, be suitable for the support style of the big space truss structure of various horizontal forces.
4, method is simple, has good economic benefit and popularizing value.
Description of drawings
With embodiment the utility model is further specified with reference to the accompanying drawings below.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure, 1, the bearing ball, 2, the bearing gusset, 3, the nut cushion block, 4, base-plate, 41, through hole, 5, pre-embedded steel slab, 51, the bearing baffle plate, 52, shear key, 53, gusset, 6, lower support structure, 7, crab-bolt, 71, nut, 8, rubber pad, 81, the rubber stop block.
The specific embodiment
A kind of rack bearing as shown in Figure 1 and Figure 2 comprises a seat body of mainly being made up of bearing ball 1, bearing gusset 2 and base-plate 4, and mainly installs and fixes assembly by what pre-embedded steel slab 5, crab-bolt 7 and nut 71 were formed; Described bearing ball 1 bottom is fixedly connected on the described base-plate 4 by a plurality of described bearing gussets 2, through hole 41 is arranged on the base-plate 4, described crab-bolt 7 is vertically passed described through hole 41 and described pre-embedded steel slab 5, the bottom of crab-bolt 7 is fixed in the lower support structure 6, the top of described crab-bolt 7 is connected on the described base-plate 4 by described nut 71, crab-bolt 7 welds together with described pre-embedded steel slab 5, described pre-embedded steel slab 5 is fixed on the upper surface of described lower support structure 6, and the bottom of pre-embedded steel slab 5 is fixed with shear key 52; Be provided with rubber pad 8 between described pre-embedded steel slab 5 and the described base-plate 4, the through hole that passes for described crab-bolt 7 is arranged on the rubber pad 8, on the described pre-embedded steel slab 5 bearing baffle plate 51 is arranged, leave apart from a between the side of bearing baffle plate 51 and adjacent base-plate 4, this be structure movably apart from a, it is determined under the prerequisite of having considered caoutchouc elasticity rigidity according to designing and calculating.The radius of described through hole 41 is not less than the radius sum apart from a and described crab-bolt 7, and when touching bearing baffle plate 51 with assurance base-plate 4, crab-bolt 7 is not born horizontal force.When bearing moves to bearing baffle plate 51, just reached movably extreme position of structure design, the horizontal force after discharge this moment promptly passes to the lower support structure by the bearing plate washer by built-in fitting and shear key.
