Description
Technical field
The present invention relates to steel box-girder beam section general assembly construction field, specially more curve superposition steel box-girder upside-down construction toolings
Mould.
Background technology
To meet manufacture, transport and installation requirement, long Large Steel box beam requirement component is whole using segmented in manufactory
Assembling；With popularization and application of the steel construction in bridge field, more curve superposition steel box girder forms gradually increase, curved section
Assembling it is complex, traditional mould is located in after sectional terminates and cannot reuse, take be build-- cut
Except the-- circulation pattern built（Traditional steel case fine strain of millet assembly moulding bed mostly using rigid frame posture structure type as job platform,
Alignment code plate is then welded on platform, the transverse and longitudinal slope of steel box-girder panel is controlled by the different positioning absolute altitude of each code plate, together
Shi Liyong sides rigid support system and lateral register code plate control the multidirectional linear of steel box-girder web, treat that this steel box-girder group is welded
After completing lower tire, existing alignment code plate is cut off, welding alignment code plate is rearranged according to the geometric dimension of next round steel case fine strain of millet, and
Adjusting control absolute altitude and lateral displacement）, this pattern takes, effort, feed consumption, and reduces construction efficiency, product quality people not to the utmost
Meaning.On the other hand, being continuously increased with span and quantity, especially under conditions of parallel organizing construction, to manufacture of steel structure
Producer's production capacity, place resource etc. propose challenge.The present invention aims at overcoming above-mentioned problems, proposes more curve superposition steel
Box beam upside-down construction fixture clamping fixture, with reach complicated linear steel case fine strain of millet rapidly and efficiently, continuous-flow type construction operation condition, it is ensured that production
Product high-precision construction quality.
Invention content
The present invention cannot be reused to solve conventional code plate in current steel box-girder upside-down method of hull-section construction assembling process, low construction efficiency
The technical issues of, a kind of more curve superposition steel box-girder upside-down construction fixture clamping fixtures are provided.
Realization that the present invention adopts the following technical solutions：More curve superposition steel box-girder upside-down construction fixture clamping fixtures, packet
Babinet is included, the upper pillar stand and lower pillar stand being located at respectively above and below babinet are fixed on babinet, the lower end of lower pillar stand is fixed on
In pedestal, worm gear mechanism is equipped in babinet, the leading screw in upper pillar stand and lower pillar stand cylinder, leading screw are provided on worm gear
Top is provided with branch fastener.
Make the code plate for supporting beam body segmentation into fixture clamping fixture, the adjustable tire changed by the use of the adjustability of leading screw as curved surface
Tool support.Fixture clamping fixture connect fixation with ground using pre-embedded bolt.By top plate, longitudinal rib integral multiple distance and tabula Board position point
Cloth is set, and the leading screw of corresponding lifting force is selected according to the weight of segmentation babinet, and the coverage area of leading screw will meet steel box-girder top plate
The requirement of size and welding contracted quantity meets the various top plate line styles variation of different segmentations by the height of adjusting screw, and
According to the height change of top surface camber, in different location using stroke leading screw support of different sizes, the height of adjusting needed for leading screw
Angle value can utilize computer to be obtained according to beam body offset by coordinate conversion.Stent on the outside of the web position of steel box-girder both sides
Along the longitudinally mounted lateral mould of box beam on keel, specific location is determined by diaphragm plate, web, using this mould to web transverse direction
Displacement is adjusted, and meets the curvature line style requirement of web.
Above-mentioned more curve superposition steel box-girder upside-down construction fixture clamping fixtures, the upper end of leading screw is provided with Thrust nut.
Beneficial effects of the present invention：
Compared with traditional steel case fine strain of millet assembling support system, the present invention has the technical characterstics such as efficient, saving, high-precision,
Need not and cross section geometry linear according to the different curves of steel box-girder remove again, lay alignment code plate, only need to pass through screw
The upper and lower of mould, side-to-side dimensions are adjusted, greatly save the activity duration, the expenses such as artificial, material and machinery have significantly
It reduces, specific manifestation has the beneficial effect that：
1st, versatility：The code plate for being originally used for that beam body is supported to be segmented makes leading screw into, utilizes the self-locking performance and adjustability of leading screw
As the linear variation of more curves powerful support, it can be achieved that above and below multiple spot, left and right adjusting, it is real to the steel box-girder of different linear variations
It is existing general.
2nd, high efficiency：Reduce the production process for making different curve steel box beam code plates.
3rd, economies：Reduce the use of the manpower, material, machinery that make different code plates, while realize continuous productive process,
It is smaller to manufactory's production capacity and place resource requirement.
4th, high-precision：Using leading screw, realize and curve steel box beam is positioned and constrained in elevation and lateral multiple spot, it can be effective
Ensure that manufacture is linear to coincide with design theory value.
