Described lattice column hoisting frame is characterized in that: the paralell of structure platform is selected the I shape channel-section steel for use.

When the utility model uses, carry out successively as follows:

1. measurement setting-out: position according to the drawing position at the construction field (site);

2. ground is handled: the load-bearing ground is tamped rolled, lay concrete cushion;

3. lay subgrade case on ground, subgrade case is laid and has been strengthened the rack bearing area, can make the sedimentation of whole lattice column hoisting frame even simultaneously;

4. the adjusting bearing is set, and the utility model requires the center line verticality to be controlled in the 30mm, regulates the verticality of bearing during construction by transit survey, to control perpendicularity deviation of the present utility model;

5. regulating connection box dagger on the bearing, the frame dagger is made up of fundamental segment, and fundamental segment adopts on ground horizontal assembly unit to finish, and is in place by the loop wheel machine integral hoisting at the scene;

6. the top adopts fundamental segment that four frame daggers are connected firmly, and connects to utilize the otic placode bolt to connect or welding.Set up a structure platform then.

The utility model adopts the lattice column hoisting frame as interim bearing platform, bearing platform is confined to the problem of permanent lattice column in having solved that large-scale steel structure is whole and promoting, compare with traditional permanent lattice column, the utlity model has following advantage: 1. the utility model is provisional bearing platform, can be with tearing open with dress, easy and simple to handle, application is wider; 2. fabrication and installation are simple, can be placed into the stress point position with crane after ground is with the loose mail assembly unit; 3. can regulate the lattice column height according to the actual requirement of engineering; 4. the utility model reaches 2kN as the reagency that bearing platform can bear.
