Description
Technical field
The technical field of derrick crane installation foundation is the utility model is related to, it is especially a kind of to be built for large span bridge
If the tower crane foundation used, more particularly to its mechanical connecting structure.
Background technology
With the development of society, the construction of input and the expansion, such as the Yellow River cross a river highway bridge of infrastructure.Use tower
Formula crane, installation difficulty is larger, in riverbed or waterborne, while takes into account left and right sides bridge floor.Traditional foundation structure is
Through that can not be applicable, therefore still need and existing large span Bridge Construction is further improved with infrastructure of tower crane.
The content of the invention
The purpose of this utility model is to provide a kind of tower crane foundation used for large span bridge construction, its
Make full use of installation foundation of the bridge pier lower cushion cap as derrick crane.Overcome shortcoming and defect present in prior art.
To achieve these goals, the technical solution of the utility model is：It is a kind of to be used for what large span bridge construction used
Tower crane foundation, including be located at the bridge pier lower cushion cap of both sides respectively, set up between the bridge pier lower cushion cap of the both sides have it is auxiliary
Beam is helped, the upper surface of bridge pier lower cushion cap is embedded with built-in fitting, and the built-in fitting is existed by a block welding gusset and rectangular vertical distribution
The rib for welding gusset lower surface is formed, and the rib is perpendicular to welding gusset lower surface, and gusset is rectangular that dress is distributed with for welding
Distribution, the upper end of rib is located in above-mentioned pilot hole, and rib upper end is fixedly welded in pilot hole, and the lower end of rib is downward
It is embedded into bridge pier lower cushion cap, following table EDS maps of the floor stringer close to both ends weld with above-mentioned welding gusset upper surface, floor stringer
Section it is approximate in I-shaped, genesis analysis has a bearing rib in the cell body of floor stringer both sides, under column crane mast section
Side is provided with the small supporting leg of tower crane, and the upper end of the small supporting leg of tower crane is fixedly connected with the lower end of column crane mast section, tower crane ramuscule
The lower end of leg is fixed on the upper surface of floor stringer by fastening bolt, the brace rod below the rigging position face of the small supporting leg of tower crane
Plate.
The utility model discloses a kind of tower crane foundation used for large span bridge construction, the foundation structure
Reused bridge pier lower cushion cap, and two pieces of built-in fittings of pre-plugged in each bridge pier lower cushion cap, two bridge pier lower cushion caps it
Between set up twice auxiliary girder steel, finally by tower crane supporting leg be fixed on auxiliary girder steel on, four tower crane supporting legs constitute tower crane mark
The installation base portion of quasi- section, derrick crane is installed in the top of tower crane supporting leg, both sides bridge floor Bridge Pier Construction can be covered simultaneously.Originally set
Meter scheme is practical, processing cost is low, convenient to assemble and disassemble, easy to use.

Embodiment
With reference to the accompanying drawings, the utility model is further described below.
The utility model discloses a kind of tower crane foundation used for large span bridge construction, including position respectively
Bridge pier lower cushion cap 1 in both sides, it is different from prior art and is：Being set up between the bridge pier lower cushion cap 1 of the both sides has auxiliary
Beam 2, the upper surface of bridge pier lower cushion cap 1 are embedded with built-in fitting, and the built-in fitting is existed by a block welding gusset 3 and rectangular vertical distribution
The rib 4 of welding gusset 3 lower surface is formed, and the rib 4 welds 3 rectangular distribution of gusset perpendicular to welding gusset 3 lower surface
There is pilot hole, the upper end of rib 4 is located in above-mentioned pilot hole, and the upper end of rib 4 is fixedly welded in pilot hole, rib 4
Lower end is embedded into downwards in bridge pier lower cushion cap 1, is longer than the length positioned at middle rib 4 positioned at the length of the rib 4 of periphery, auxiliary
Beam 2 is helped to be welded close to following table EDS maps and the above-mentioned upper surface of welding gusset 3 at both ends, the section of floor stringer 2 is approximate in I-shaped,
Genesis analysis has bearing rib 5 in the cell body of the both sides of floor stringer 2, and the lower section of column crane mast section 6 is provided with tower crane ramuscule
Leg 7, the upper end of the small supporting leg 7 of tower crane are fixedly connected with the lower end of column crane mast section 6, and the lower end of the small supporting leg 7 of tower crane passes through
Fastening bolt is fixed on the upper surface of floor stringer 2, meanwhile, welded, the branch below the rigging position face of the small supporting leg 7 of tower crane
Support gusset 5.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the utility model specific implementation is confined to these above-mentioned explanations.For the common skill of the utility model art
For art personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should
It is considered as belonging to the scope of protection of the utility model.
