Description
Technical field
The present invention relates to prefabricated pile interconnection technique field, especially a kind of self-locking prefabricated pile attachment means and its pile extension side
Method.
Background technology
Using the prefabricated concrete-pile of batch production more than present foundation pile, it is possible to achieve mass production, will be prefabricated during construction
Stake transports building-site to, and stake is delivered into designed elevation using modes such as hammering, static pressure, bears the lotus of top buildings or structures transmission
Carry, successively be formed by connecting prefabricated pile one using measures such as welding, mechanical connection, anchor slurries by its foundation pile.
At present, the topmost form of preformed pile connecting is to be welded to connect, by lower section sunk pile to the position of 1m or so from the ground
Put, the stake of upper section is lifted to the stake of lower section, welding is started after adjustment, each weld time is about 40 minutes or so, entirely
The holdup time is long in the earth formation for pile body, easily causes pile sinking difficulty, or even do not reach expected design object；Section stake weldering up and down
After the completion of connecing, connector temperature is higher, and during pile sinking, underground water is met in junction portion suddenly, pile crown is quenched, and weld seam becomes fragile, and directly affects
The stress performance of prefabricated pile；In addition, pile sinking scene is typically open work, in joint welding, influenceed by rain, wind,
Weldquality is difficult guarantee, is hidden some dangers for pile extension, can also directly affect the quality of pile foundation；When wind and rain is larger, it is impossible to construct, shadow
Ring construction speed and efficiency；Additionally, after joint of precast piles welding, it is difficult to carry out preservative treatment, there is corrosive ions geology ring
Under border, joint durability should not ensure.
Existing foundation pile, prefabricated pile is mainly taken welded reinforcement or concrete on end plate to fill out core and is anchored with the connection of cushion cap
The formal layout of reinforcing bar, because by the larger factor of stake inner core cleaning difficulty, concrete is filled out core quality and is difficult to ensure that.Prefabricated
During stake resistance to plucking, wadding weft variation failure is easily caused, prefabricated pile framing connection is unreliable, and on the other hand, concrete fills out core anchoring
There is larger eccentric throw in reinforcing bar, stress is unreasonable with reinforcing bar in prefabricated pile；Welded reinforcement is due to the skill by welder on end plate
The influence of each side such as art level, weather, construction technology, inefficiency, quality is difficult to ensure.
In addition, prefabricated staking has larger eccentric throw after being commonly present the bar connecting of stake and stake, stake and cushion cap, or reinforcing bar is received
, by indirect transfers such as end plates, the stress of prefabricated pile is not reasonable, can cause the waste of material for power.
