Technical field

The present invention relates to steel truss girder docking technique fields, and in particular to a kind of docking facilities of big segment steel truss girder and docking Method.

Background technique

With the fast development of economy and scientific and technical innovation, the bridge span in transport development is also progressively longer.Large span Bridge is mostly cable-stayed bridge, and for cable-stayed bridge, for especially combined heavily loaded cable-stayed bridge, compared to solid web girder, adopt It can reduce self weight with steel truss girder and increase rigidity to be better adapted to the load-carrying members compared with large span.

The installation of steel truss girder is by multiple segment steel truss girders mostly to realization is fetched, in the prior art, a kind of Conventional interconnection method is that temporary staging is set up below docking region, and setting is supported to the lower edge of frame steel truss girder on temporary staging, Adjustment winding up highly and to frame steel truss girder position to frame steel truss girder is suspended in midair by crane, and crane persistently suspends in midair, to butt welding After the completion, crane is removed.But when large span stayed-cable bridge uses big segment steel truss girder integral erection, due to big segment steel truss Beam has been formed from great stable structure, and therefore, front fulcrum counter-force is huge at Standing position of a crane, leads to the big segment steel truss of frame The position of beam and the banjo fixing butt jointing to frame steel truss girder is big in vertical, axially opposing deformation, in this case, according to above-mentioned normal Interconnection method is advised, big segment steel truss girder can not be directly docked by the way of punch.

Therefore, one of goal of the invention of the invention aims to solve the problem that problem of the big segment steel truss girder in docking.

Summary of the invention

In view of the deficiencies in the prior art, the purpose of the present invention is to provide a kind of big segment steel truss girders to tipping It sets and interconnection method, effectively adjusts the section and wait the relative deformation between section of setting a roof beam in place of having set a roof beam in place, realize big segment steel truss girder docking.

To achieve the above objectives, in a first aspect, the embodiment of the present invention provides a kind of docking facilities of big segment steel truss girder, For docking two big segment steel truss girders, defining two big segment steel truss girder is set a roof beam in place section and section to be set a roof beam in place；It is described Segment steel truss girder includes: greatly

Second pair of drawing mechanism, both ends are respectively provided at the middle part of the set a roof beam in place section, section to be set a roof beam in place；It draws when described second Dui When to drawing, a pair of of extension bar wait in section of setting a roof beam in place is corresponding close to extension bar into the section of having set a roof beam in place for mechanism；

Top lifting mechanism comprising lift up device；The lift up device is set to described wait on winding up in section of setting a roof beam in place, and the top lifting The top of device is fixedly installed；When the upward top lifting of the lift up device, the section to be set a roof beam in place is pushed.

Based on the above technical solution, the top lifting mechanism further include:

One shoulder pole girder, one end are connect with winding up in section of having set a roof beam in place, and the other end is connect with wait winding up in section of setting a roof beam in place, institute State the top that shoulder pole girder is installed in the lift up device；When the lift up device jacks up the shoulder pole girder upwards, the section to be set a roof beam in place In wind up and move downward.

Based on the above technical solution, the top lifting mechanism further include:

Two third ear mounts, be installed in respectively section of having set a roof beam in place wind up and the winding up of section to be set a roof beam in place on, the shoulder pole girder Both ends pass through pin shaft respectively and are detachably connected with two third ear mounts.

Based on the above technical solution, first pair of drawing mechanism includes:

Steel cable, both ends are connected with two opposite cross bearers respectively；

Jack is set at least one end of the steel cable, for shrinking the length of the steel cable.

Based on the above technical solution, first pair of drawing mechanism further include:

Two first ear mounts are installed in the section and wait set a roof beam in place in section of having set a roof beam in place, described in each first ear mount and one respectively Steel cable is detachably connected.

Based on the above technical solution, extension bar is connect in one end of second pair of drawing mechanism and section of having set a roof beam in place, The other end is connect with wait the vertical bar in section of setting a roof beam in place close to this to extension bar.

Second aspect, the embodiment of the present invention also provide a kind of docking facilities of big segment steel truss girder, are used for big by two Segment steel truss girder is docked, and defining two big segment steel truss girder is set a roof beam in place section and section to be set a roof beam in place；The big segment steel truss girder Include:

The several groups string beam element of parallel interval setting, every group of string beam element include one wind up, a lower edge, at least one with It is described wind up the vertical bar being connected with lower edge and two be set to outside all vertical bars to extension bar；

Several cross bearers, wind up described in each adjacent two between be equipped at least two cross bearers, wait in section of setting a roof beam in place Cross bearer is oppositely arranged with the cross bearer in section of having set a roof beam in place；

The docking facilities include:

First pair of drawing mechanism, one end for connect with the cross bearer in section of having set a roof beam in place, the other end for wait set a roof beam in place Corresponding cross bearer connection in section；

Second pair of drawing mechanism, both ends are respectively used to be located at the middle part of the set a roof beam in place section, section to be set a roof beam in place；

Top lifting mechanism comprising lift up device；The bottom of the lift up device be used to be set to it is described wait winding up in section of setting a roof beam in place, Top is for being fixedly installed；The lift up device is used in upward top lifting, pushes the section to be set a roof beam in place.

The third aspect, the embodiment of the present invention also provide a kind of interconnection method of big segment steel truss girder, and the interconnection method is logical It crosses above-mentioned docking facilities such as to realize, the step of interconnection method includes:

Step 1: will align and dock with all lower edges in section of having set a roof beam in place wait all lower edges in section of setting a roof beam in place；

Step 2: using first pair of drawing mechanism to drawing Duan Yuyi to be set a roof beam in place to set a roof beam in place the cross bearer in section, slightly aligning section to be set a roof beam in place In to extension bar with set a roof beam in place in section to extension bar；

Step 3: using second pair of drawing mechanism to drawing Duan Yuyi to be set a roof beam in place to set a roof beam in place the middle part of section, exactitude position and to reception frame In beam section to extension bar with set a roof beam in place in section to extension bar；

Step 4: using the upward top lifting of lift up device in top lifting mechanism, pushing is described wait winding up in section of setting a roof beam in place, and contraposition is simultaneously It winds up described in docking, that is, completes the docking of big segment steel truss girder.
