Therefore, the precision rolling deformed steel bar hung basket primary truss is good in reuse ratio and capable of saving the using cost of the hung basket.

Description

Fining twisted steel main truss cradle frame
Technical field
The utility model relates to a kind of main truss cradle frame, is specifically related to a kind of fining twisted steel main truss cradle frame.
Background technology
In the bridge construction, commonly used to cradle construction, common Hanging Basket has triangle Hanging Basket and Diamond-Shape Form Traveler on the engineering.Usually the main truss cradle frame comprises two girders, connects by crossbeam between the girder, and column vertically is set on the crossbeam, is connected by pull bar between column and the crossbeam two ends, and pull bar can be distributed to the load-bearing of Hanging Basket on the overall beam, makes that Hanging Basket can cantilever construction.
In the prior art, Hanging Basket is normally assembled by all kinds of section bar welding, and the big weight of volume is heavier, and a secondary Hanging Basket generally weighs several tons even tens of tons.Hang in the construction, guaranteeing for the Hanging Basket own wt requirement is arranged also under the intensity of Hanging Basket own and the hard conditions, more little its pressure for construction bridges of Hanging Basket weight is also just more little; And because the bearing capacity difference of the Hanging Basket of a project demand, a secondary Hanging Basket can only be applicable to one or several project usually, but the recycling rate of waterused of Hanging Basket material is lower.
The utility model content
Main purpose of the present utility model provides a kind of in light weight, flexible for installation, main truss cradle frame that material can reuse.
For achieving the above object, the technical scheme that adopts is: a kind of fining twisted steel main truss cradle frame, the girder and the column that comprise vertical connection, between described column top and the girder end pull bar coupling assembling is set, it is characterized in that: described pull bar coupling assembling comprises hinged block and finish rolling deformed bar; Described hinged block is hinged on column and the girder, and through hole is set on the hinged block; Through hole is passed in described finish rolling deformed bar end, and the nut that is threaded on the projecting end, and nut is kept out with the hinged block formation and cooperated; Corresponding with through hole on two hinged blocks that same finish rolling deformed bar connects many groups are set.
Pull bar on the main couple of the present utility model adopts finish rolling deformed bar, and screw-thread steel has the advantage that can reduce member area and weight under same intensity requires, the weight that can save main couple greatly because its surface is provided with screw thread; The hinged hinged block in column top and girder end, through hole is set on the hinged block, finish rolling deformed bar passes the through hole on the hinged block, the screw thread steel attaching nut who passes, column and girder are coupled together, nut is kept out with the hinged block formation and is cooperated, be that nut is by being threaded on the finish rolling deformed bar, hinged block is propped up, as the projecting end that stretches out the finish rolling deformed bar of the hinged block nut that is threaded, by the fixing reinforcing bar of nut and hinged block butt, perhaps nut can be screwed into the counterbore of hinged block hinged block setting, nut is screwed into fixedly reinforcing bar of counterbore again.With corresponding on two hinged blocks that same finish rolling deformed bar connects many group through holes are set, be that the aperture of through hole and the cross-sectional diameter of finish rolling deformed bar are complementary, and can peg graft the respectively two ends of same finish rolling deformed bar of every group of through hole, and the number of steel bars of interting can be regulated according to the required load-bearing of actual Hanging Basket, so just finish rolling deformed bar can be reused.
The utility model fining twisted steel main truss cradle frame, by with finish rolling deformed bar column being connected with crossbeam, saved the own wt of main couple, and the quantity of finish rolling deformed bar can be regulated according to the load-bearing of actual Hanging Basket, so the utlity model has good recycling rate of waterused, save the Hanging Basket use cost.

The specific embodiment
Specify as follows with reference to accompanying drawing: a kind of fining twisted steel main truss cradle of the utility model frame, comprise girder 1 and column 3, girder 1 is vertical mutually with column 3, and column 3 tops and girder 1 two ends are hinged hinged block 7 respectively, on the hinged block 7 through hole is set; Finish rolling deformed bar 5 passes through hole column 3 is connected with girder, pass the finish rolling deformed bar 5 end thread attaching nuts 8 of hinged block 7, also can the counterbore that can be screwed into nut 8 be set at the hinged block 7 that passes finish rolling deformed bar 5, nut 8 is screwed into counterbore, fixing so more firm, connect corresponding many groups through hole is set on the hinged block 7 of same finish rolling deformed bar, the diameter that is through-hole aperture and finish rolling deformed bar 5 is complementary, and every group of two ends that through hole can intert same finish rolling deformed bar 5.
Further, described finish rolling deformed bar 5 specifications are DN32, and described sets of vias number is more than or equal to 6.What the utility model adopted is the standard finish rolling deformed bar, namely meets the reinforcing bar of the requirement of " GB1499.1-2008 steel concrete steel part 1: hot calendering round bar ".It is the finish rolling deformed bar 5 of DN32 that the utility model adopts specification in actual applications, and number of steel bars can reach the required requirement of strength of general bridge construction during more than or equal to 6.
Further, described column 3 is symmetrical arranged two groups with girder 1 minute surface, connects by crossbeam 2 between two girders 1, connects by truss 4 between two columns 3.Two groups of columns 3 that namely arrange and girder 1 connect by truss 4 between the column 3 about the centre position symmetry of the crossbeam 2 between two girders 1, and this is in order further to increase the intensity of main truss cradle frame, to prevent it because long-term load-bearing distortion.
Further, described column 3, crossbeam 2 and girder 1 be vertical connection in twos, and girder 1 is positioned at the below of column 3 and crossbeam.That is to say that column 3, crossbeam 2 and girder 1 are vertical in twos, and intersect at same position, girder 1 is arranged under crossbeam 2 and the column 3, the weight that column 3 and crossbeam 2 carry is directly conducted to girder 1 by compressive stress and is born, the flexural stress that produces is less, and girder 1 major part when practice of construction is to be fixed on the bridge portion of having built, and so just the power that is subjected to can be dispersed on the bridge of building, thereby make main couple more firm.
Further, described column 3 tops are connected by diagonal member 6 with crossbeam 2 one ends.The end and the column top that are about to crossbeam couple together with diagonal member 6.The direct spandrel girder of crossbeam when actual bridge construction, the easy stressed bending in its end by the connection of diagonal member 6, makes column can share the drop-down strength that the part beam-end is born.
Further, described truss 4 arranges stiffener 9 with column 3 junctions.That is to say by modes such as welding steels truss 4 is fixed again with the place that column 3 is connected.This is because its junction is easy to generate deformation under external force most, by the intensity that stiffener 9 can improve the junction is set.
Further, be connected by hound 10 between described truss 4 and the crossbeam 2.That is to say between truss 4 and crossbeam 2 hound 10 is set, hound 10 can disperse the load-bearing of part truss 4, also can be so that whole truss 4 structures are more stable.
Further, described truss 4 quantity are more than or equal to 2 and all be parallel to crossbeam 2.A plurality of truss 4 columns 3 have better firm effect; Crossbeam 2 normally is fixed on the girder 1, and its weight capacity is stronger, truss 4 is disposed in crossbeam 2 parallels, can be so that the weight of disperseing by hound 10 can be dispersed on the crossbeam 2 by average mark.
Further, connect by hound 10 between the described truss 4.Like this can column 3 and truss 4 further firm effect is arranged.
