Abstract
The method that tower crane removes standard knot under specifically a kind of restricted clearance of the present invention;It is characterized in that: including that tower crane crane arm is adjusted to opposite direction with platform is removed;Two standard section of tower crane are sling in front end using tower crane crane arm;Clump weight is fixed, and pulley is installed on weight arm, and the wirerope of crane arm is changed onto pulley, starts tower crane standard knot and removes work;After suspension hook is by standard knot lifting fastening, tears peace open platform sliding support on platform and be pushed outwardly, at this point, standard knot is released together on platform sliding support, the standard knot after release is just just at the downward vertical of suspension hook;Then crane hook is sling in control room upwards, then starts to withdraw platform sliding support;The standard knot of dismounting starts vertically to hang onto ground;Repeat above step.In the case that building building influence tower crane normally removes standard knot, causes tower crane crane arm that cannot tear platform open with peace not on same one side, this method can be used to carry out dismounting operation to tower crane.
Description
Technical field
The present invention relates to the realm of building construction, the method for tower crane dismounting standard knot under specifically a kind of restricted clearance.
Background technique
In building engineering construction, tower crane is the essential power jacking equipment in construction site, before commencement of works just
It must not only accomplish the effective boundary of works area in covering scene to tower crane perfecting program layout drawing, it is also contemplated that after the completion of good later period
The tower crane planning removing work, therefore carry out tower crane arrange it is the work being highly desirable, but construction site is often
Unexpected thing can be always encountered, the arrangement of tower crane and later period build up the factors such as rear tower crane dismounting and slightly consider not
The dismounting of later period tower crane will be influenced entirely.
Summary of the invention
The purpose of the present invention is to provide the methods that tower crane under a kind of restricted clearance reversely utilizes counter-jib to remove standard knot.
A kind of method that tower crane removes standard knot under restricted clearance, including
Step 1: tower crane crane arm is adjusted to opposite direction with platform is removed, and ensures that no barrier influences tower crane
It is vertical to remove;
Step 2: slinging two standard section of tower crane in front end using tower crane crane arm, the two standard knots as interim counterweight,
Guarantee tower crane front and back weight balancing;
Step 3: lift under crane arm two interim clump weights of standard knot are fixed, and the fixation of check criteria section is arranged
The security situation applied;
Step 4: a small-sized pulley gear is installed on weight arm, is then adjusted the wirerope of crane arm, by steel wire
Rope changes on the pulley gear onto weight arm, still can control steel wire rope hook in tower crane control room and carries out lifting work;
Step 5: starting tower crane standard knot and remove work, shift standard knot onto peace using hydraulic jacking device and tear platform open, then will
Suspension hook lifts standard knot;
Step 6: after suspension hook is by standard knot lifting fastening, tearing peace open platform sliding support on platform and be pushed outwardly, at this point,
Standard knot is released together on platform sliding support, and the standard knot after release is just just at the downward vertical of suspension hook;
Step 7: and then sling crane hook upwards in control room, then start to withdraw platform sliding support;
Step 8: the standard knot of dismounting starts vertically to hang onto ground, the standard knot that subsequent land arrangement mechanical work will remove
It is transferred to other places for not hindering scene current;
Step 9: repeating five~step 8 of above step, and standard knot is removed to tower crane to controllable height, starts to arrange truck crane
Tower crane upper end all parts are segmented and are removed.
In the case that building building influence tower crane normally removes standard knot, cause tower crane crane arm that cannot tear platform open with peace
Not on same one side, this method can be used to carry out dismounting operation to tower crane.This method reversely removes standard knot using counter-jib principle.
This construction method can be used for tower crane peace and tear the architectural engineering that platform laying is not controlled open, has stronger operability in the field, passes through
Benefit is evident for Ji, also ensures that tower crane can be removed safely.
Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
A kind of method that tower crane removes standard knot under restricted clearance, including
Step 1: when outer adhesion tower-crane hydraulic jacking system tower crane use finishes, according to on-site actual situations tower crane crane arm
The two can not be adjusted to opposite direction, and ensure that clear influences hanging down for tower crane with dismounting platform at same one side
It is straight to remove;
Step 2: slinging two standard section of tower crane in front end using tower crane crane arm, the two standard knots as interim counterweight,
Guarantee tower crane front and back weight balancing.In addition it is to ensure that slinging standard knot there are enough height, it is therefore an objective to be unlikely to tower crane and drop to
When certain altitude, and the standard knot counterweight of front end has been landed, and just can not balance the weight of front and back.
Step 3: lift under crane arm two interim clump weights of standard knot are fixed, and check criteria section is solid
The security situation to set down measures;
Step 4: a small-sized pulley gear is installed on weight arm, is then adjusted the wirerope of crane arm, by steel wire
Rope changes on the pulley gear onto weight arm, still can control steel wire rope hook in tower crane control room and carries out lifting work;
Step 5: starting tower crane standard knot and remove work, shift standard knot onto peace using hydraulic jacking device and tear platform open, then will
Suspension hook lifts standard knot;
Step 6: after suspension hook is by standard knot lifting fastening, tearing peace open platform sliding support on platform and be pushed outwardly, at this point,
Standard knot is released together on platform sliding support, and the standard knot after release is just just at the downward vertical of suspension hook;
Step 7: and then sling crane hook upwards in control room, then start to withdraw platform sliding support;
Step 8: the standard knot of dismounting starts vertically to hang onto ground, the standard knot that subsequent land arrangement mechanical work will remove
It is transferred to other places for not hindering scene current;
Step 9: repeating five~step 8 of above step, and standard knot is removed to tower crane to controllable height, starts to arrange truck crane
Tower crane upper end all parts are segmented and are removed.
In the case that building building influence tower crane normally removes standard knot, cause tower crane crane arm that cannot tear platform open with peace
Not on same one side, this method can be used to carry out dismounting operation to tower crane.This method reversely removes standard knot using counter-jib principle.
This construction method can be used for tower crane peace and tear the architectural engineering that platform laying is not controlled open, has stronger operability in the field, passes through
Benefit is evident for Ji, also ensures that tower crane can be removed safely.
