Abstract
The utility model relates to a bearing bracket. The bearing bracket comprises forming truss platforms which are symmetrically arranged, wherein one side of the upper end of each forming truss platform is connected with an upper hinge seat by a connection steel pin; one side of the lower end of the forming truss platform is connected with a lower hinge seat by a connection steel pin; and the upper hinge seat and the lower hinge seat are connected with the upper hinge seat and the lower hinge seat which are symmetrically arranged by connection shafts and JM anchorage devices, thus solving the construction technical problems of a bearing bracket at the top of a suspended-casting continuous beam pier during bridge project construction. The bearing bracket has the characteristics of being simple in the stress of a bracket structure, safe and reliable, convenient to install and detach, and capable of being repeatedly used for many times. The bearing bracket can be widely applied to construction processes for various concrete piers.
Description
Technical field
The utility model relates to a kind of bearing support, particularly a kind of cantilever method continuous beam pier top load bearing bracket.
Background technology
Cantilever method continuous beam is common method for designing in Longspan Bridge design.Cantilever method continuous beam pier top 0# piece generally adopts the construction of welded type cast-in-site of bracket method, mostly set up in the following way bracket: be close to pier shaft sidewall template and bury pre-embedded steel slab underground, steel truss is being specified to processing place welding fabrication on request simultaneously, after pier shaft form removal, the steel truss of moulding is welded on and on pre-embedded steel slab, forms bracket.Utilize bracket formwork erection, reinforcing bar be installed, cast pier top 0# block concrete, assistance platform that also can be using this bracket as assembling construction Hanging Basket.Bracket is removed the general gas cutting that adopts and is cut off.The weak point of its existence is, causes that material recycling rate of waterused is low, waste is large.In addition with pre-embedded steel slab, to be welded and fixed be mainly vertical position welding and overhead welding to welded type bracket, and owing to adopting, the bridge pier of bracket job practices is generally higher, and the operating space that workman is fixed welding to steel truss is little, and welding quality is difficult for guaranteeing.
Utility model content
Its object of the utility model is just to provide a kind of bearing support, has carrier structure stressed simple, safe and reliable, and mounting or dismounting are convenient, the feature that can be repeatedly used.
The technical scheme that realizes above-mentioned purpose and take, comprise the moulding truss platform being arranged symmetrically with, described moulding truss platform upper end one side connects upper free bearing through connecting steel pin, moulding truss platform lower end one side connects lower free bearing through connecting steel pin, and described upper free bearing and lower free bearing are through upper free bearing and the lower free bearing of connecting axle and JM ground tackle connected symmetrical dendrimer layout.
Compared with prior art this device has the following advantages.
1, owing to having adopted free bearing to connect the structure design of moulding truss platform, thereby it is stressed simple, safe and reliable to have carrier structure, simple load and unload feature.
2, owing to having adopted free bearing to connect the structure design of moulding truss platform, thereby there is dismountable feature, can be repeatedly used.

The specific embodiment
Embodiment
This device comprises the moulding truss platform 3 being arranged symmetrically with, as shown in Figure 1, described moulding truss platform 3 upper end one sides connect upper free bearing X through connecting steel pin 5, moulding truss platform 3 lower end one sides connect lower free bearing Y through connecting steel pin 5, and described upper free bearing X and lower free bearing Y are through upper free bearing X and the lower free bearing Y of connecting axle and JM ground tackle 2 connected symmetrical dendrimers layouts.
Described upper free bearing X and lower free bearing Y bottom surface are provided with pressure-resistant rubber pad 4, as shown in Figures 3 and 5.Described connecting axle is high-strength fining twisted steel 1.
At least 2 of described connecting axles.
This device embodiment is comprised of high-strength fining twisted steel 1, JM ground tackle 2, moulding truss platform 3, upper free bearing X, lower free bearing Y, pressure-resistant rubber pad 4, connection steel pin 5.By stretch-draw fining twisted steel 1, free bearing X, Y are anchored on pier shaft sidewall, then moulding truss platform 3 are passed through to connect steel pin 5 pin joints on free bearing X, Y, the upper load that utilizes free bearing to conduct oneself with dignity and bear with the frictional force between pier wall and support reaction balance bracket.Pressure-resistant rubber pad 4 between free bearing and pier wall is for increase free bearing with frictional force between pier wall, avoid free bearing steel plate to cause damage to pier shaft concrete simultaneously.
During construction pier shaft, in specific bit, install preformed hole, pier shaft concrete reaches after design strength by the high-strength fining twisted steel 1 of stretch-draw, free bearing X, Y are anchored on pier shaft sidewall, subsequently the shaped steel moulding truss platform 3 of machine-shaping is linked on free bearing X, Y by steel pin, finally the same side steel truss is formed to integral bracket by welded connection part and jointly bear top working load.When bracket is removed, first connecting piece between steel truss is dismantled, the coupling pin 5 of then dismantling between steel truss 1 and free bearing X, Y is removed steel truss, finally by putting, opens dismantle free bearing X, Y and high-strength fining twisted steel 1, JM ground tackle 2.
Cantilever method bridge pier top 0# piece construction bracket system is comprised of high-strength fining twisted steel 1, JM ground tackle 2, moulding truss platform 3, upper free bearing X, lower free bearing Y, pressure-resistant rubber pad 4, coupling pin 5.During construction pier shaft, in specific bit, install preformed hole, after pier shaft form removal, can in pier shaft preformed hole, wear high-strength fining twisted steel 1, the upper free bearing X and the lower free bearing Y that on backing plate, post pressure-resistant rubber pad 4 are installed, the supporting JM ground tackle 2 of same fining twisted steel 1 is screwed on simultaneously.Until pier shaft concrete strength, reach after design strength, can use punching top by calculated value stretch-draw fining twisted steel 1, tighten JM ground tackle 2 free bearing X or Y are anchored on pier shaft sidewall.Subsequently the shaped steel moulding truss platform of machine-shaping 3 is passed through to coupling pin 5 pin joints on free bearing, finally the same side steel truss is formed to integral bracket by welded connection part and jointly bear top working load.When bracket is removed, first connecting piece between steel truss is dismantled, the coupling pin 5 of then dismantling between steel truss 1 and free bearing X, Y is removed steel truss 1, finally by putting dismounting free bearing X, a Y and high-strength fining twisted steel 1, JM ground tackle 2.
