Abstract
The utility model discloses a device used to temporarily fix a ball support and a corresponding bearing carrier. The device used to temporarily fix the ball support and the bearing carrier is characterized by including a hoop, wherein the hoop is arranged on a footstone of the ball support and surrounds a baseboard of the ball support. A plurality of intervals are disposed on a vertical corner stop block of the hoop, the lower end of the intervals is fixed on the hoop, and the upper end of the intervals is supported on a component of a top cover plate of the ball support, and the plurality of the intervals are arranged on a horizontal stop block of the hoop. The device used to temporarily fix the ball support and the bearing carrier is simple in production, convenient to operate, and obvious in action. The device used to temporarily fix the ball support and the bearing carrier not only overcomes the shortcomings of the ball support, but also avoids inbuilt embedded parts in a bridge structure.
Description
Technical field
The utility model is a kind of spherical bearing and temporary fixed equipment of rib-lifting section of making, and is applicable in the construction of steel work arch bridge or other large bridge spherical bearing and its consolidation device of bearing carrier structure mutually.
Background technology
Along with the fast development of china's overall national strength, the steel work arch bridge is handsome in appearance thereupon, and stressed simple, characteristics such as convenient for maintaining are selected for use by increasing Urban Bridge construction, and relative splicing accuracy also requires increasingly high between steel member sections.In the present large bridge, generally use spherical bearing.Usually it comprises a lamina tecti, the spherical liner plate of a base plate and between lamina tecti and base plate.Because most spherical bearings self do not have stopping means, general lamina tecti and base plate only have four interim fastening bolts.When steel member tonnage is big, in installation process, the fastening bolt strength deficiency exists bolt crooked with the size of opposing moment of flexure, and spherical bearing generation translation displacement and corner displacement phenomenon cause steel member sections that lateral deviation is arranged, and have a strong impact on into the bridge quality.
Usually solution has pre-buried fining twisted steel when the pontic concreting, or pre-embedded steel slab.Its shortcoming has: 1, often pre-buried position is inaccurate, and deviation is big.2, the pre-buried while, the steel member also need weld and connect corresponding supporting firmware.3, after pre-buried the cutting off, corrosion takes place in pre-buried muscle easily that be retained in pontic.
The utility model content
The objective of the invention is deficiency, a kind of simple and effective solving device is provided to the above-mentioned background technology.This device is welded by channel-section steel or i iron, makes simple, easy to operate, effect significantly, not only overcomes the spherical bearing self-defect but also avoid in crossstructure, burying underground middle built-in fitting.
The technical scheme that the utility model provides is following:
A kind of device that is used for spherical bearing and respective carrier member temporary consolidation, it comprises:
One anchor ear, it is positioned on the foundation stone at spherical bearing place, around being provided with around the spherical bearing base plate;
A plurality of intervals are arranged on the vertical corner limited block on the anchor ear, and its lower end is fixed on the anchor ear, the upper end is supported in the member soffit on the spherical bearing lamina tecti; And
A plurality of intervals are arranged on the horizontal limited block on the anchor ear.
Described anchor ear is that channel-section steel or i iron are welded.
In the preferred embodiment of the utility model, described anchor ear is a polygon, and wherein the limit number is 4-6.
In the preferred embodiment of the utility model, described anchor ear is a rectangle.
In the preferred embodiment of the utility model, described vertical corner limited block and horizontal limited block are through being fixedly welded on the anchor ear.
In the preferred embodiment of the utility model, described horizontal limited block one end is fixed on the anchor ear, and the other end is fixed on the base plate of spherical bearing or on the foundation stone under the base plate.
The utility model is directed against defective of the prior art: most spherical bearings self do not have stopping means, and general lamina tecti and base plate only have four interim fastening bolts.When steel member tonnage is big, in installation process, the fastening bolt strength deficiency exists bolt crooked with the size of opposing moment of flexure.For this defective provides a kind of simple and effective solving device, this device is welded by channel-section steel or i iron, makes simple, easy to operate, effect significantly, not only overcomes the spherical bearing self-defect but also avoid in crossstructure, burying underground middle built-in fitting.
The utility model possesses following advantage:
1. make simple, easy for installation;
2. cost is low, and result of use is good;
3. practical, be convenient to promote.
Description of drawings
Fig. 1 is the perspective view of the utility model.
The specific embodiment
The specific embodiment of the utility model is with reference to Fig. 1.A kind of device that is used for spherical bearing and respective carrier member temporary consolidation, it comprises a rectangular anchor ear 1, it is welded by four channel-section steels, is respectively two transverse channel steels 2 and two vertical channel-section steels 1.
On every vertical channel-section steel 1, be respectively equipped with two longitudinal spacing pieces 4; On every transverse channel steels 2, be respectively equipped with two cross spacing pieces 3.This cross spacing piece 3 is also processed for channel-section steel.
On every vertical channel-section steel 1 and transverse channel steels 2, be respectively equipped with two vertical vertical corner limited blocks 5.Its lower end is fixed on the anchor ear, the upper end is supported on the member on the spherical bearing lamina tecti.
The fabrication and installation flow process of the utility model is following:
1, behind arch springing (member) location of spherical bearing top, temporarily arch springing is not broken away from lifting appliance, in order to avoid the spherical bearing fastening bolt deforms.
2, utilize channel-section steel to be welded into anchor ear 1; Its shape and size and spherical bearing pinner are basic identical, and every limit is welded two limited blocks 3 or 4 respectively, is used to limit translational degree of freedom; Limited block one end dieback is in pinner or base-plate position, and the other end is welded on the anchor ear.
3, according to the physical length blanking of anchor ear basis to arch springing (member), the length of making vertical corner limited block 5.For closely knit, do not produce sedimentation and be connected with arch springing (member) spot welding, weld entirely with anchor ear and be connected.
4, hoisting machine tool and arch springing (member) are broken away from, convert into by this temporary consolidation equipment as support.
5, continue other arch rib member of lifting, this moment, bearing was spacing fully by the utility model, can not produce relative displacement.
