Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
The every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Embodiment
A kind of step flow chart of steel construction hinged-support construction as shown in Fig. 1, the attached drawing disclose specifically
Steel construction hinged-support construction, detailed process includes the following steps：
S1, the processing of steel construction hinged-support；The step is specific as follows：
S101, drawing in-depth, are hinged-support by the in-depth of fixed end bearing.
The in-depth of steel construction fixed end bearing is hinged-support by the characteristics of being applied in combination according to construction site drag-line and steel construction,
Ensure joints.It is specific as shown in Fig. 2.
S102, hinged-support pivot pin hole machined.
It is required that ensureing pin shaft hole machining accuracy, each hole must be aligned.
According to in-depth node diagram, the pin shaft hole of the pre-buried part of hinged-support is four rows, and four rounds connect after being passed through by axis pin
Upper component.Requirement on machining accuracy is very stringent, once precision is unsatisfactory for requiring, axis pin will not pass through four rounds, to scene
Construction infection is serious.
Pivot pin material is 40Cr, chemical composition：C (0.37~0.44%), Si (0.17~0.37%), Mn (0.80~
1.10%), quenched to use heat treatment mode.
S2, surveying setting-out；
S3, steel construction hinged-support are pre-buried；
Concrete construction will be carried out after steel construction hinged-support installation of embedded parts, leveling.
S4, the installation of hinged-support steel construction bolt；The step is specific as follows：
S401, hinged upper component installation is carried out after built-in fitting part concrete reaches design requirement.
S402, upper component laggard marketing axis in place are installed, by axis pin by pin shaft hole by superstructure and pre-buried hinged
Seat is attached.
The lifting of all superstructures, it is necessary to, correction in place in substructure, and can be carried out after fastening supporting member.
S403, upper component is fixed temporarily, is removed after the completion of cable tension.
S404, support position is checked, and axis pin is fixed.
S5, drag-line installation；
Drag-line force value controls, and every cable tension force value must be proofreaded with design value, ensures that hinged-support stress meets
Design requirement.
S6, force balance adjustment, adjust the force balance between drag-line and rotatable hinged-support, it is ensured that hinged-support is secured
Reliably.
After the completion of above-mentioned construction, it is necessary to carry out antirust, preservative treatment, avoid influencing to make stress due to corrosion.
In conclusion the characteristics of being fixed end bearing, axle power is solely subjected to according to hinged-support for prior art Central Plains bearing, this
It is rotatable hinged-support, the unlikely unexpected folding when being tied up to by typhoon with the power that drag-line forms to deepen fixed end bearing in invention
It is disconnected, to ensure structure safety.The construction of this engineering method is practical, ensured only do not sheared by axle power at node, the optimization mesh of moment of flexure
Mark.Subsequent secure use is ensured.By the force simplified of hinged-support, provided reliably for follow-up cable tension force value Modeling and Design
Guarantee.When meeting with typhoon from now on, the drawbacks of bottom fixed end bearing is broken suddenly can be effectively solved, ensures the life wealth of tourist
Production safety.Construction precision more preferably controls, once originally fixed end bearing precision be unsatisfactory for requiring to modify it is difficult big, spend cost
Greatly, hinged-support is adjustable nodal in terms of precision controlling.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, it is other it is any without departing from the spirit and principles of the present invention made by changes, modifications, substitutions, combinations, simplifications,
Equivalent substitute mode is should be, is included within the scope of the present invention.
