Description
Technical field
The present invention relates to the installation method of crane girder, refer to particularly a kind of installation method of overall combined type crane beam.
Background technology
In ANALYSIS FOR STEEL CRANE GIRDERS and ancillary system are widely used in that crane the is arranged modern industry factory building of (crane in bridge type).
The conventional mounting method is: the members such as single Pin crane girder (being generally the I-shaped cross-section), brake truss or walkway board are prefabricated in the factory respectively, then each component conveying are arrived on-the-spot.After the steel column installation, single Pin crane girder of each axis is lifted respectively, directly winch to steel column bracket place, then through overcorrection, with after post is connected and fixed, begin again to lift the members such as each brake truss, walkway board, last in the high-altitude each brake truss, walkway board welded respectively or are joined with bolts with corresponding every Pin crane girder.
Angle steel is made, walkway board is generally sheet steel and angle steel forms because brake truss is generally, and member integrated rigidity is all less, and flexibility is large, and transportation easily produces local deformation, and comparatively difficulty of installation is hung at the scene.Not only installation procedure is many for the conventional mounting method, the time is long, the lifting work capacity is large, and aloft work efficient is low, welding quality control difficulty between the member, security risk are higher.
Summary of the invention
Purpose of the present invention will overcome the existing deficiency of prior art exactly, and a kind of installation method of overall combined type crane beam is provided.
For achieving the above object, the installation method of the overall combined type crane beam that the present invention is designed after the steel column installation, carries out integral hoisting after each component assembly of making become overall combined type crane beam; Described overall combined type crane beam comprises the braking element that crane girder that two Pin are arranged in parallel and crane girder top arrange, be provided with vertical support and/or lower flange horizontal support between the described two Pin crane girders, be provided with connecting panel on the end plate of described two Pin crane girders, the top flange of described two Pin crane girders is provided with suspension ring.
Described installation method specifically may further comprise the steps:
When a. lifting by crane, first overall combined type crane beam is hung ground 0.2～0.4m, then mobile overall combined type crane beam makes the center of its centrally aligned installation site;
B. slowly overall combined type crane beam is winched to steel column over top 0.2～0.4m;
C. the space of overall combined type crane beam end is penetrated the upper prop of steel column, and move down slowly overall combined type crane beam, until the bracket place of steel column;
D. adjust overall combined type crane beam and make its bracket line of centers of aiming at steel column, in place and slow off the hook;
E. loose hook, lifting is finished, until overall combined type crane beam proofread and correct errorless after, finish adjacently stride between the overall combined type crane beam, being connected and fixed of overall combined type crane beam and bracket, overall combined type crane beam and steel column upper prop.
Further, described braking element is brake truss or walkway board.
Further, the width L in space, described braking element end is 1/2 of steel column upper prop width.
Beneficial effect of the present invention is: the present invention has changed the orthodox method that single member hangs installation one by one, with each member all at produce in factory and be assembled into integral combined member, then be transported to the on-the-spot disposable erection work of hanging of finishing Crane Beam System, operation is simplified, the lifting work capacity reduces, improved installation effectiveness, by statistics, work efficiency is 5.2 times of conventional mounting method, has greatly shortened construction period.The present invention has reduced the work capacity of on-the-spot overhead welding lifting, and the artificial quantities at scene is shifted as by the millwork equalization, and on-the-spot aloft work is transferred to the factory floor operation, and quality and installation effectiveness are made in the industrialization that is conducive to improve Crane Beam System; The minimizing of amount of high-altitude operation is of value to again workman's personal safety, has improved the safety of producing, and has embodied the production theory of " people-oriented "; Overall combined type crane beam has also increased member integrated rigidity, can reduce the local deformation that member produces in transportation, avoid the component conveyings such as brake truss, walkway board scattered, yielding, hard problem is installed, improved construction quality.The installation method of overall combined type crane beam can be widely used in the general industry factory building colonnade, and each strides the installation of hanging of Crane Beam System, can be after steel column be installed, roofing element carries out the installation of hanging of overall combined type crane beam before installing, and satisfies the mounting condition of crane runway.
