Abstract
The invention belongs to the technical field of steel truss lifting, specifically a kind of asymmetric variable cross-section different curve extra-heavy duty type large span steel truss hanging method, solves the lifting problem of this kind of steel truss.It adopts jack, wire rope, crane and roof jack, the suspension centre connecting steel wire ropes of crane and jack one end of adjustable in length, and the other end of wire rope and jack is connected to steel truss; Roof jack is vertically arranged at inner below during steel truss overhead work attitude.Hanging method of the present invention is easy, applicable, cheap, convenient, safety, and each assembly can be recycled.
Description
Technical field
The invention belongs to the technical field of steel truss lifting, be specifically related to a kind of asymmetric variable cross-section different curve extra-heavy duty type large span steel truss hanging method.
Background technology
For the lifting of asymmetric variable cross-section different curve extra-heavy duty type large span steel truss, also do not have ready-made method in prior art, and use the hanging method of conventional steel truss, complex steps, construction cost is very high, and poor stability.
Summary of the invention
The present invention, in order to solve the lifting problem of asymmetric variable cross-section different curve extra-heavy duty type large span steel truss, provides a kind of asymmetric variable cross-section different curve extra-heavy duty type large span steel truss hanging method.
The present invention adopts following technical scheme to realize:
Asymmetric variable cross-section different curve extra-heavy duty type large span steel truss hanging method, adopt jack, wire rope, crane and roof jack, the suspension centre connecting steel wire ropes of crane and jack one end of adjustable in length, the other end of wire rope and jack is connected to steel truss, and roof jack is vertically arranged at inner below during steel truss overhead work attitude;
Attitude when being in overhead work according to steel truss, determine crane hoisting point position, the tie point position of jack and wire rope and steel truss, jack between primary Calculation suspension centre to steel truss tie point and the length of wire rope, jack and wire rope are connected to steel truss, then slowly hoisting steel truss makes it just leave ground, adjustment jack length, attitude when making steel truss be in overhead work, slowly hang higher than steel truss job design height 0.3m again, before crane or backward move, then locus during work is fallen, the outer end of steel truss is connected in place with steel column concrete column and places restrictions on steel card, the inner lifting void of steel truss is placed on roof jack, the gross weight of whole steel truss is born by crane, be that non-stress can welded condition with roof jack link.
Various utensil used in the present invention is common instrument, as crane, wire rope, jack, combine during use, installation and removal are convenient, assemble according to designing requirement, just define asymmetric variable cross-section different curve extra-heavy duty type large span steel truss Lift-on/Lift-off System, be applicable to the lifting of various special type steel truss, can coordinate from different crane, availablely formerly stay rope.
Easy, applicable, cheap, convenient, safe, each assembly of hanging method of the present invention can be recycled.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention,
In figure: 1-jack, 2-wire rope, 3-crane, 4-roof jack, 5-steel truss, 6-steel core concrete column.
Detailed description of the invention
By reference to the accompanying drawings the specific embodiment of the present invention is described further.
Asymmetric variable cross-section different curve extra-heavy duty type large span steel truss hanging method, adopt jack 1, wire rope 2, crane 3 and roof jack 4, one end of the suspension centre connecting steel wire ropes 2 of crane 3 and the jack 1 of adjustable in length, the other end of wire rope 2 and jack 1 is connected to steel truss 5, and roof jack 4 is vertically arranged at inner below when steel truss 5 is in overhead work attitude;
Attitude when being in overhead work according to steel truss 5, determine crane 3 hoisting point position, the tie point position of jack 1 and wire rope 2 and steel truss 5, crane 3 hoisting point position is generally arranged along the center of gravity of steel truss, jack 1 between primary Calculation suspension centre to steel truss tie point and the length of wire rope 2, described computational methods, those skilled in the art can be known from existing geometry general knowledge, jack 1 and wire rope 2 are connected to steel truss, then slowly hoisting steel truss 5 makes it just leave ground, adjustment jack 1 length, attitude when making steel truss 5 be in overhead work, slowly hang higher than steel truss 5 job design height 0.3m again, before crane 3 or backward move, then locus during work is fallen, the outer end of steel truss 5 is connected in place with steel column concrete column 6 and places restrictions on steel card, the inner lifting void of steel truss is placed on roof jack 4, the gross weight of whole steel truss 5 is born by crane 3, be that non-stress can welded condition with roof jack 4 link.
