Abstract
The present invention relates to a kind of vertical lifting horizontal alignment hanging methods of main chord, are used for steel truss arched bridge erection.Include the following steps: that vertical lifting lifting lug is fixed using high-strength bolt in the preceding two sides in main chord one end of main chord lifting, vertically lifts and horizontal alignment conversion hanging piece is hinged with by pin shaft on lifting lug；The fixed horizontal alignment lifting lug of high-strength bolt is utilized in the two sides of the main chord other end；Vertical hanger is converted hanging piece by horizontal alignment and is connect with vertical lifting lifting lug；Vertical lifting: promoting vertical hanger makes main chord vertically encircle closure mouth small space by steel truss；It is secondary to fasten hook, horizontal alignment hoist cable is connect with horizontal alignment lifting lug；Horizontal alignment: winding level aligns hoist cable, rotates main chord with pin shaft axis horizontal to main chord；Contraposition installation main chord, after main chord is installed, hoist cable is unclamped.The present invention solves the problems, such as that small space lifting is difficult, the lifting of main chord when closing on closure section assembly suitable for steel truss arched bridge erection.
Description
Technical field
The present invention relates to steel structure hoisting field, the vertical lifting horizontal alignment hanging method of specifically a kind of main chord,
For steel truss arched bridge erection.
Background technique
Currently, more and more bridges use steel structure truss system, especially high mountain gorge area large-span steel braced arch
Bridge is especially prominent.In such steel truss arched bridge erection, when due to closing on closure section assembly, closure section narrow space and steel are reserved
Braced arch rod piece weight is big, flat is hung or integral hoisting has been unable to satisfy construction requirement using common.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of vertical lifting horizontal alignment hanging method of main chord, the party
Main chord vertical lifting is first promoted rod piece to level, to complete by closure mouth to steel truss dome portions, then secondary hook of fastening by method
Main chord installation.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
A kind of vertical lifting horizontal alignment hanging method of main chord carries out in the steps below:
Step 1 before main chord (1) lifting, is vertically hung in the two sides of main chord (1) one end using high-strength bolt (8) fixation
Ear (2) vertically lifts on lifting lug (2) and is hinged with horizontal alignment conversion hanging piece (4) by pin shaft (3)；In main chord (1) other end
Two sides it is fixed horizontal alignment lifting lug (7) using high-strength bolt (8)；
Step 2, hoist cable (5) are connect by horizontal alignment conversion hanging piece (4) with vertical lifting lifting lug (2)；
Step 3, vertical to lift: raising sling (5) makes main chord (1) is vertical to encircle the mouth small space that joins the two sections of a bridge, etc by steel truss；
Step 4, it is secondary to fasten hook, hoist cable (6) is connect with horizontal alignment lifting lug (7)；
Step 5, horizontal alignment: raising sling (6) rotates main chord (1) to main chord (1) for axis in level with pin shaft (3)
Shape；
After main chord (1) is installed, hoist cable (5), hoist cable (6) are unclamped for step 6, contraposition installation main chord (1).
The present invention by adopting the above technical scheme, compared with prior art, the beneficial effect is that:
It solves the problems, such as that existing method is lifted in small space difficult, one kind is provided newly by small space for large-scale rod piece
Hanging method is particularly suitable for the lifting of main chord when steel truss arched bridge erection closes on closure section assembly.
Detailed description of the invention
Fig. 1 is the vertical lifting schematic diagram of the embodiment of the present invention；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the horizontal alignment schematic diagram of the embodiment of the present invention；
Fig. 4 is the top view of Fig. 3；
In figure: 1, main chord；2, lifting lug is vertically lifted；3, pin shaft；4, horizontal alignment converts hanging piece；5, hoist cable is vertically lifted；6,
Horizontal alignment hoist cable；7, horizontal alignment lifting lug；8, high-strength bolt.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and embodiments.
Referring to Fig. 1 to Fig. 4, a kind of vertical lifting horizontal alignment hanging method of main chord relates generally to first vertical lifting
Horizontal alignment again, the specific steps are as follows:
(1) before main chord 1 lifts, the fixed vertical lifting lifting lug 2 of high-strength bolt 8, vertical lifting are utilized in the two sides of 1 one end of main chord
Horizontal alignment is hinged with by pin shaft 3 on dress lifting lug 2 and converts hanging piece 4；High-strength bolt 8 is utilized in the two sides of 1 other end of main chord
Fixed horizontal alignment lifting lug 7；
(2) it will vertically lift hoist cable 5 and be connect by horizontal alignment conversion hanging piece 4 with vertical lifting lifting lug 2；
(3) vertical lifting: promoting vertical lifting hoist cable 5, makes the vertical small space for encircleing closure mouth by steel truss of main chord 1；
(4) secondary to fasten hook, horizontal alignment hoist cable 6 is connect with horizontal alignment lifting lug 7；
(5) horizontal alignment: winding level aligns hoist cable 6, rotates main chord 1 with 3 axis of pin shaft horizontal to main chord 1；
(6) contraposition installation main chord 1, after main chord 1 is installed, will vertically lift hoist cable 5 and horizontal alignment hoist cable 6 unclamps,
So far the contraposition installation of main chord 1 is completed.
The above is only specific embodiments of the present invention, but protection of the invention is without being limited thereto, the skill of any the art
Art personnel the thinkable variation or substitution being equal with the technical program technical characteristic, all cover in protection scope of the present invention
Within.
