Abstract

The utility model discloses a support seat for a slant legged rigid frame bridge. The support seat comprises an upper anchoring sleeve, an upper pendulum, shaft housings, a hinge shaft, a lower pendulum and a pre-buried sleeve; the upper pendulum is fixedly connected with a slant legged rigid frame through the upper anchoring sleeve; the lower pendulum is fixedly arranged on a concrete cushion seat through the pre-buried sleeve; the hinge shaft is rotatably connected between the upper pendulum and the lower pendulum; and the two ends of the hinge shaft are sleeved with the shaft housings and are fastened by locking nuts. The support seat provided by the utility model is simple in structure, rational in design, convenient in installation; all functions of the support seat can be realized; the corner is larger than that of a basin-shaped rubber support seat or a ball-shaped steel support seat; and the support seat can be installed in a slant way, thus, the application range is wide.

Description

A kind of slant legged rigid frame bridge is used bearing

Technical field

The utility model belongs to the bridge pad technical field, particularly a kind of bearing that is used on the firm structure of battered leg.

Background technology

At present, in bridge erection, advantage such as particularly under the such orographic condition of abrupt slope deep valley, the firm structure of battered leg is because span ability is big, and steel using amount is few and by extensively utilization.Be used at present on the firm structure of battered leg bearing all the right and wrong level install, if adopt benzvalene form, ball shaped steel bearing can't realize the bearing function, also can bring great difficulty to installation.

The utility model content

The purpose of the utility model is exactly to above-mentioned prior art problems, provides a kind of slant legged rigid frame bridge to use bearing, not only is convenient to install, and can realizes all functions of bearing.

The purpose of the utility model realizes through following technical proposals:

A kind of slant legged rigid frame bridge is used bearing; Comprise anchoring sleeve, go up pendulum, axle sleeve, hinge, the bottom, pre-buried sleeve; Last pendulum is affixed through last anchoring sleeve and the firm structure of battered leg; The bottom is fixed on the concrete base through pre-buried sleeve, the hinge that is rotationally connected between the upper and lower pendulum, and the two ends socket axle sleeve of hinge is also fastening by locking nut.

Further, said hinge middle part is provided with shaft shoulder boss, is used to bear horizontal force.

Above-mentioned axle sleeve plays a part to connect goes up pendulum, hinge and the bottom, and locking nut is set outside axle sleeve, last pendulum, hinge, the bottom and axle sleeve is locked and prevented the play of hinge.

are fixed through fixing synchronously mode with the embedded board of pre-buried sleeve one, guarantee installation accuracy.

This bearing can be applicable on the LARGE SPAN STEEL BRIDGE; Realize rotating function through hinge, act on the power of laying out, be delivered to the hinge center with rigidity angle (35 ° to 45 °) diffusion; Be passed to the bottom with rigidity angle (35 ° to 45 °) diffusion downwards again, at last power be passed on the concrete base.

The beneficial effect of the utility model is: simple in structure, reasonable in design, be convenient to install, can realize all functions of bearing, and corner is bigger than pot rubber bearing, ball shaped steel bearing, and tiltable is installed, and the scope of application is extensive.
