Described Bar Anchorage plate is made up of reinforcing bar, anchor plate；Described reinforcing bar is l shape reinforcing bar, and main body is imbedded at its l end
In frame column, its other end stretches out body frame trestle surface；Described anchor plate is angle steel shape, one side and l shape reinforcing bar
The external part stretching out body frame trestle surface is welded and fixed, and another side of anchor plate opens up multiple through holes and bolt passes through
This through hole is affixed with heavy in section gooseneck framework outer end.
Described body frame trestle is made up of four heavy in section frame columns, and four heavy in section frame columns are in rectangular layout, greatly
Four outer ends of section steel crossbeam frame are separately fixed on four heavy in section frame columns, and heavy in section gooseneck framework is apart from building ground
Face 100mm-300 mm.
Pre-embedded steel slab on body frame trestle, by fixing for heavy in section gooseneck framework stress on body frame trestle.
The present invention is a kind of construction method of tower crane pedestal, comprises the following steps:
(1) surveying setting-out；
(2) to built-in fitting, pre-buried position is accurately positioned；
(3) making of built-in fitting, after body frame trestle reinforcing bar binding completes acceptance(check), embedded bar anchor on body frame trestle
Gu plate；
(4) installation of embedded parts completes, disturbing concrete, heat and moisture preserving maintenance in time after concreting is qualified, and carries out in time
Built-in fitting position check measurement；
(5) heavy in section gooseneck framework is installed after body frame trestle concrete strength reaches 70%, heavy in section gooseneck framework with pre-
Embedded part adopts high-strength bolt to connect.
After such scheme, because the present invention includes many body frame trestles, polylith Bar Anchorage plate, heavy in section steel horizontal stroke
Beam framework；Described polylith Bar Anchorage plate is embedded on many body frame trestles respectively, the outer end of heavy in section gooseneck framework
It is fixed on polylith Bar Anchorage plate, have the advantage that
1st, because the outer end of heavy in section of the present invention gooseneck framework is bolted on polylith Bar Anchorage plate so that this
Bright heavy in section gooseneck framework tower crane is convenient to assemble and disassemble, and time and labour saving saves land again, meets green construction requirement.
2nd, compared with traditional tower crane, the tower-crane foundation structure form of this present invention is simple, energy-conserving and environment-protective, and repeating makes
With.
3rd, because the heavy in section gooseneck framework tower crane basis instrument of the present invention is on body frame trestle, e.g., the present invention can
It is arranged on basement roof, agent structure conversion layer is first-class, but stress is on body frame trestle, rather than stress is in basement
Top board or agent structure conversion layer flooring.
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
