Description
Technical field
The present invention relates to the realm of building construction, specifically the assembled portable crane span structure of steel work industrial premises and for the engineering method of roofing construction.
Background technology
The steel work industrial premises because its speed of application is fast, the characteristics such as, environmental protection good from heavy and light, anti-seismic performance have extensively been approved in construction work, replaced gradually heavy reinforced concrete structure and obtained generally application in the industrial premises design.When the roofing to the steel work industrial premises is constructed, generally can use full hall frame now.Adopt full hall frame as handling frame, cost is high, high to the ground flat degree requirement, can impact to ground construction poor stability when support body is higher.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of saving cost of having deducted a percentage, good stability, and the assembled portable crane span structure of the steel work industrial premises that can not impact ground construction.The invention also discloses the engineering method of the assembled portable crane span structure of above-mentioned steel work industrial premises for roofing construction.
Purpose of the present invention is achieved through the following technical solutions: the assembled portable crane span structure of steel work industrial premises, comprise two joint bearing joints and be located at the splicing joint between two joint bearing joints, described bearing joint and splicing joint include two upper horizontal supervisors that be arranged in parallel, two lay respectively under two upper laterally supervisors and the lower horizontal supervisor parallel with upper horizontal supervisor, laterally be responsible for or connect the many vertical direct-connected adapters of horizontal supervisor under two on connecting two, and connect laterally lower laterally supervisor's many vertical straight tube connectors under supervisor and upper horizontal supervisor, under the connected two upper laterally supervisors of any vertical direct-connected adapter or two, laterally supervisor is vertical, connected horizontal supervisor is vertical with lower horizontal supervisor for any vertical straight tube connector, in two upper laterally supervisors of described bearing joint and splicing joint, two upper laterally supervisors connect one to one, under two of bearing joint laterally in supervisor and splicing joint under two laterally supervisor connect one to one, the other end that in described bearing joint, under two, laterally supervisor connects splicing joint end relatively all is connected with roller.Now, generally can use crane while in the steel work industrial premises, transporting weight, steel work industrial premises top is provided with for loading the crane girder of the inner crane of factory building, and crane girder is provided with crane runway, after the crane suspension heavy weight by travelled the transhipment of weight on crane runway.The present invention is in when application, and two ends of the present invention are located on two crane girders that be arranged in parallel, and roller is located in crane runway, by roller, at the crane runway internal shift, and then completes displacement of the present invention.
The quantity of described splicing joint is more than two joints, more piece splicing joint is located between two joint bearing joints in turn, two upper laterally supervisors of two upper laterally splicing joints that supervisor is adjacent of any joint splicing joint connect one to one, laterally be responsible for and connect one to one under two of the splicing joint that under two that any joint splicing saves, laterally supervisor is adjacent, two joint bearings joints save the splicing joint with two of two ends in more piece splicing joint respectively and are connected.The present invention adopts bearing joint and more piece splicing joint to carry out compound splicing, so, when the present invention does not use detachable become two independently bearing joint and a plurality of independently splicing save, make to invent and be convenient to be transferred to another steel work industrial premises and again utilize.
The assembled portable crane span structure of steel work industrial premises, also comprise vertically oblique tube connector and vertical tiltedly tube connector, many vertical direct-connected adapters that two upper laterally supervisors are upper to be connected with two upper laterally between supervisor, laterally all form a plurality of horizontal rectangular zone between horizontal supervisor under the upper many vertical direct-connected adapters that are connected of supervisor and two under two, be equipped with vertically oblique tube connector in each horizontal rectangular zone, every vertically oblique tube connector two ends are connected to two places, diagonal angle, horizontal rectangular zone; Every upper laterally supervisor and lower horizontal supervisor under it and be connected this on laterally supervisor with its under the lower horizontal many vertical straight tube connectors of being responsible for form a plurality of vertical rectangular areas, be equipped with vertical tiltedly tube connector in each vertical rectangular area, every vertical tiltedly tube connector two ends are connected to two places, diagonal angle, vertical rectangular area.The present invention by many vertically tiltedly tube connectors and the vertical tiltedly tube connector of Duo Gen make structure of the present invention more firm, compact, and stressed more even when the present invention is applied.

Step 2, complete the manufacture of splicing joint and bearing joint, and in the factory building of construction by assembled length and the smooth good place of direction, bearing is saved and splice after joint is well placed by the order designed and requirement and assembled, should strictly control planeness and axis in assembling process well, then on the ground the two ends of crane span structure are established to the freely-supported point, carry out loading by the design load requirement and carry out loading test on crane span structure;
Step 3, by crane span structure, winch to above the crane girder track after, the roller of the bearing on crane span structure both sides joint is adjusted, four rolling misalignment crane girder centre-line of track deviation should be met and is less than or equal to 5mm, the difference in height of four rolling is less than 5mm;
Step 4, in gantry top, set up scaffold, and at scaffold top bed board, guardrail is set, horizon bar, the bar of sweeping the floor, bridging, form operating platform;
Step 5, carry out roofing construction on operating platform.
