Abstract
The utility model relates to a prefabricated steel pipe column for the static load detection of a cast-in-place pile, and belongs to the technical field of construction equipment. The steel pipe column comprises a cylindrical steel plate barrel with a closed bottom, wherein rectangular reinforcing ribs of which the length is equal to that of the steel plate barrel are uniformly distributed on the outer wall of the steel plate barrel along the circumferential direction; an annular flange which extends along the radial direction is arranged on the top of the steel plate barrel and fixedly connected with one side of each rectangular reinforcing rib; and the external diameter of the steel plate barrel is smaller than the internal diameter of an envelope circle defined by vertical steel bars of the cast-in-place pile. The steel pipe column is conveniently and quickly constructed and can be turned over, the construction period can be shortened, and cost is saved.
Description
Technical field
The utility model relates to a kind of piling strtucture testing equipment, relates in particular to a kind of castinplace pile static load and detects pre-fabricated steel pipe pillar, belongs to the construction equipment technical field.
Background technology
At present; The single-pile vertical orientation static pressure test that interts in the pore-creating filling pile construction of pile groups adopts following processing method usually: excavate → abolish the ultra concrete placing of pile crown to complete concrete surface → assembling reinforcement → installation steel form (being generally circular steel plate is welded) → concreting (being higher than 1 grade of design strength grade of concrete) → moisture-keeping maintaining → backfill → static load levelling of the land → installation jack, time pile extension construction of time broken pile crown → 2, time excavation → dismounting steel form → 2, girder steel → pile concrete block → static loading test → 2 near choosing stake (randomly draw 1% quantity of a number total amount to after date 28 day age of concrete) → stake.In this test the processing of pile crown is wasted time and energy; The disposable steel plate concrete pile crown of making will be removed after test is accomplished; Manpower and material to construction are great wastes; And since whole process intersect in pile foundation, pile cover and cushion cap or the foundation construction, bigger to the influence of follow-up construction period.
The utility model content
The technical problem that the utility model will solve is that the problem to the existing castinplace pile static load detection pile crown processing expense that wastes time and energy is expected provides a kind of castinplace pile static load to detect pre-fabricated steel pipe pillar.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of castinplace pile static load detects pre-fabricated steel pipe pillar; The cylindrical steel plate bucket that comprises bottom lock; The outer wall of said steel plate bucket circumferentially is evenly distributed with the rectangle reinforcing rib isometric with it; The top of said steel plate bucket has radially the collar flange that extends, one side said collar flange and said rectangle reinforcing rib be connected the internal diameter that the envelope that the external diameter of said steel plate bucket is surrounded as less than the castinplace pile vertical reinforcement is justified.
Preferably, said steel plate bucket is built-in with reinforcing cage.
Preferably, have a pair of hanger hole on the said collar flange symmetrically, wherein be coated with T font hanger.
Preferably, the below of said steel plate bucket also is lined with circular shim, has a ring through hole that can pass the castinplace pile vertical reinforcement on the said circular shim.
The pre-fabricated steel pipe pillar of the utility model adopts the prefabricated steel bucket with reinforcing rib and collar flange that is placed in the castinplace pile top to replace the disposable steel plate and the concrete pile follower of existing castinplace pile top field fabrication, and the beneficial effect that has is:
1, installation and dismounting are convenient, fast, can shorten the duration that pile crown is handled.
2, castinplace pile static load detection pre-fabricated steel pipe pillar can have enough to meet the need use, practices thrift cost.

The specific embodiment
Embodiment one
The castinplace pile static load of present embodiment detects pre-fabricated steel pipe pillar such as Fig. 1, shown in Figure 2; The cylindrical steel plate bucket of processing by the 20mm roll of steel plate 1 that comprises bottom lock; The outer wall of steel plate bucket 1 circumferentially is welded with the rectangle reinforcing rib 2 isometric with it equably; The collar flange 3 that radially extends that the top vertical welding T-Ring shape steel plate of steel plate bucket 1 forms, the broadside welding of doughnut-shaped steel plate and rectangle reinforcing rib 2, the round internal diameter of envelope that the external diameter of steel plate bucket 1 is surrounded as less than castinplace pile vertical reinforcement 5.
Embodiment two
It is the improvement on embodiment one basis that the castinplace pile static load of present embodiment detects pre-fabricated steel pipe pillar; Like Fig. 3, shown in Figure 4; Different is except that identical with embodiment one for it: steel plate bucket 1 is built-in with reinforcing cage 4 and concrete perfusion 6 to concordant with the top of collar flange 3; Have a pair of hanger hole 7 on the collar flange 3 symmetrically, wherein be coated with T font hanger 8.
Embodiment three
It is the improvement on embodiment two bases that the castinplace pile static load of present embodiment detects pre-fabricated steel pipe pillar; Like Fig. 5, shown in Figure 6; Different is except that identical with embodiment one for it: the below of steel plate bucket 1 also is lined with two circular shim 10, has a ring through hole 11 that can pass castinplace pile vertical reinforcement 5 on the said circular shim.
During use; At first design elevation is abolished in the top stake of castinplace pile; Adopting high strength contraction-free grouting concrete to carry out levelling in the pile crown face handles; The vertical reinforcement 5 that leaks outside of straightening castinplace pile top and vertical reinforcement 5 passed the through hole of offering on two circular shim 10 11 is close on the pile crown face of castinplace pile two circular shim 10 again, then the castinplace pile static load is detected pre-fabricated steel pipe pillar and lifts on the circular shim 10 in the vertical reinforcement 5; Check steel pipe column upper flat degree once more after removing T font hanger 8, can jack be installed at its top and carry out the static load detection.
The castinplace pile static load of the utility model detects pre-fabricated steel pipe pillar and is not limited to above-mentioned each embodiment, and all employings are equal to the technical scheme that replacement forms, and all drop on the protection domain of the utility model requirement.
