Abstract
The invention discloses a fully-symmetrical prestress assembled type tower crane foundation connected to a pile foundation and mainly applied to tower crane foundations in constructional engineering field. The fully-symmetrical prestress assembled type tower crane foundation mainly comprises strip-shaped blocks A (1), strip-shaped blocks (2) with pre-embedded bolts, strip-shaped blocks B (13), steel strands (3), anchor tools (5), connection steel plates (8) and piles (11). A construction process of the fully-symmetrical prestress assembled type tower crane foundation connected to the pile foundation mainly comprises the following steps: firstly constructing the piles (11), then lifting the strip-shaped blocks A (1), and inserting pile main bars (9) of the piles (11) into holes C (15) of the strip-shaped blocks A (1); subsequently lifting other strip-shaped blocks, inserting U-shaped steel plates (7) of the strip-shaped blocks into arc-shaped grooves (14) of the adjacent strip-shaped blocks, then enabling the steel strands (3) to successively pass through holes A (6) of the strip-shaped blocks, applying prestress and fixing via the anchor tools (5); and finally enabling the pile main bars (9) to pass through holes B (10) of the connection steel plates (8), fixing the whole tower crane foundation to the piles (11) through nuts, and finishing mounting the tower crane foundation.
Description
Technical field
Present invention is mainly used for building engineering field tower crane foundation.
Background technology
The patent of invention that I has authorized: a kind of holohedral symmetry prestressed assembly formula foundation for tower crane, the patent No.: ZL201210114414.8, pile foundation is not combined, runs into soft foundation inapplicable by this patent.
Summary of the invention
Pin-connected panel foundation for tower crane is combined by the present invention with pile foundation, greatly strengthen the resistance to capsizing of tower crane, is simultaneously suitable for soft foundation, expands the range of pin-connected panel foundation for tower crane.
It is an advantage of the current invention that:
1.
Flat shape is holosymmetric, overcomes weak axle problem.
2.
Plane combination is simple, only split basic plane in a direction, Shi Hanzhang is also a direction, need the most two-way Shi Hanzhang like that not necessarily like beam and slab type or beam type assembly tower crane and cause basic plane deformation after assembly, particularly fix the relative change in location of four groups of pre-embedded bolts of tower crane and the relative position error of producing.
3.
The present invention is after Shi Hanzhang anchoring, and the basic stress after assembly is reasonable, and the frictional force between bar blocks and bar blocks can resist the shear stress suffered by basis；The steel strand wires arranged up and down (
3
) moment of flexure suffered by basis can be resisted
。
4.
Prefabricated components are simple, and shape is single, the most prefabricated, are not easy to damage and substitute easily during lifting and assembly.
5.
Relatively for beam foundation, the present invention is more reliable and more stable, and joins reinforcing bar amount and reduce, and saves amount of reinforcement, although multiplex concrete amount, but adds basis weight, and when work to overcoming tower crane, the vibrations load of generation is helpful, adds security reliability.
6.
For fix four groups of pre-embedded bolts of tower crane support be embedded in respectively two bar blocks (
2
On), make to be embedded in two bar blocks two groups of pre-embedded bolt groups along bar blocks long side direction and do not have assembled error.
7.
Pin-connected panel foundation for tower crane is combined by the present invention with pile foundation, greatly strengthen the resistance to capsizing of tower crane, can be suitably used for again soft foundation simultaneously, expands the range of pin-connected panel foundation for tower crane.
