Abstract
The utility model discloses a tower crane base structure in the type of combination of steel latticework columns and a concrete bearing platform shaped like Chinese character 'hui'. The tower crane base structure comprises four rectangular steel latticework columns which are arranged vertically, wherein level diagonal bridgings and vertical diagonal bridgings are arranged among the steel latticework columns, the bottom portions of the steel latticework columns are inserted inside drilled grouting piles, the drilled grouting piles are placed below a base plate of a basement, the concrete construction bearing platform is arranged below the base plate of the basement in a pouring mode, the concrete bearing platform shaped like Chinese character 'hui' is poured on the top portions of the steel latticework columns, and the bottom portion of a tower crane is installed on the concrete bearing platform shaped like Chinese character 'hui'. In consideration of the influence of self-weight of the concrete bearing platform to the steel latticework columns, the concrete bearing platform is constructed into a shape like Chinese character 'hui' to form a tower crane base in the type of combination of the steel latticework columns and the concrete bearing platform shaped like Chinese character 'hui', the base is adopted so that safety of tower crane construction can be guaranteed, the problem that vertical transport in deep foundation pit construction is conducted in advance is resolved well, evenness of concrete can be controlled well, and the requirement that the tower crane is installed on the base is guaranteed.
Description
Technical field
The utility model relates to the tower crane construction field, is specifically related to steel lattice column Back Word type concrete bearing platform combined type tower crane job practices.
Background technology
Development along with urban construction, building trends towards developing multi-storey basement, the degree of depth and the scale of basement are increasing, for the needs of constructing, consider that tower crane need use ahead of time, the digging when while constructs in order to reduce tower crane is dark, and high cushion cap tower crane, the i.e. pattern of pile foundation+steel lattice column+concrete bearing platform (steel platform) in the deep foundation ditch more and more adopted in the job site.Pile foundation+steel lattice column+steel platform pattern is because the steel welding quality is difficult to assurance, and cost is higher, has limited its scope of application.
The utility model content
Technical problem to be solved in the utility model just provides a kind of steel lattice column Back Word type concrete bearing platform combined type tower crane structure, can guarantee the safety of tower crane construction, well solved the problem that the vertical transport of deep foundation pit construction is inserted in advance again, and the concrete planeness can be controlled preferably, guarantees to reach the requirement that tower crane is installed thereon.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: steel lattice column Back Word type concrete bearing platform combined type tower crane structure, comprise that four are vertically arranged rectangular steel lattice column, be provided with horizontal cross brace and vertical bridging between the described steel lattice column, insert in the bored pile described steel lattice column bottom, described bored pile is located under the basement bottom board, built concrete structure cushion cap under the described basement bottom board, it is characterized in that: Back Word type concrete bearing platform has been built at described steel lattice column top, and the tower crane bottom is installed on the described Back Word type concrete bearing platform.
As preferably, described steel lattice column cross section is square.
Steel lattice column Back Word type concrete bearing platform combined type tower crane job practices may further comprise the steps:
Step 1: make single steel lattice column;
Step 2: bored pile construction, and insert when the bored pile construction single steel lattice column in the bored pile;
Step 3: install template, colligation Back Word type concrete bearing platform beam steel, and concreting, Back Word type concrete bearing platform is stretched in single lattice column bottom, and is during concreting that the tower crane built-in fitting is pre-buried good;
Step 4: treat after Back Word type concrete bearing platform concrete strength reaches requirement tower crane to be installed;
Step 5: along with the excavation of the earthwork progressively weld horizontal bridging and vertical bridging, at the bottom of being excavated to basement bottom board;
Step 5: install structure cushion cap template, colligation structure cushion cap reinforcing bar, concreting;
Step 6: basement bottom board concreting;
Step 7: tower crane is finished using, and during dismounting, steel lattice column is cut off in basement bottom board top mark high position, finishes tower crane dismounting work.
The utility model considers that the concrete bearing platform deadweight is to the influence of steel lattice column, concrete bearing platform is made the Back Word type, form steel lattice column Back Word type concrete bearing platform combined type tower crane, adopt this basis can guarantee the safety of tower crane construction, well solved the problem that the deep foundation pit construction vertical transport is inserted in advance again, and the concrete planeness can be controlled preferably, guarantees to reach the requirement that tower crane is installed thereon.

Described steel lattice column cross section is square.The described steel lattice column cross section length of side is 480mm, and the bar diameter that described bored pile uses is 18mm.
In addition, steel lattice column Back Word type concrete bearing platform combined type tower crane job practices may further comprise the steps:
Step 1: make single steel lattice column;
Step 2: bored pile construction, and insert when the bored pile construction single steel lattice column in the bored pile;
Step 3: install template, colligation Back Word type concrete bearing platform beam steel, and concreting, single lattice column stretches into Back Word type concrete bearing platform certain-length, and is during concreting that the tower crane built-in fitting is pre-buried good;
Step 4: treat after Back Word type concrete bearing platform concrete strength reaches requirement tower crane to be installed;
Step 5: along with the excavation of the earthwork progressively weld horizontal bridging and vertical bridging, at the bottom of being excavated to basement bottom board;
Step 5: install structure cushion cap template, colligation structure cushion cap reinforcing bar, concreting;
Step 6: basement bottom board concreting;
Step 7: tower crane is finished using, and during dismounting, steel lattice column is cut off in basement bottom board top mark high position, finishes tower crane dismounting work.
