Background technology
Along with the raising of the significance level of modern architecture and the variation of form of structure; Construction work improves constantly the ground processing requirements; All kinds of in the past structure foundations handle used concrete tubular pile, concrete prefabricated side stake as the support between bearing stratum and the superstructure and power transmission rod member mostly as permanent pressure bearing pile, mainly bear vertical uniform load q, but underground structures such as underground garage, market, pond get more and more at present; The essential stake commonly used of specific occasions such as basement is uplift pile; Several years ago, a lot of resistance to plucking engineerings are selected pile for prestressed pipe for use, because its joint is welded to connect drawbacks such as unreliable; Causing certain potential safety hazard to engineering, formally sends the documents and it is used as uplift pile limits in areas such as existing Jiangsu, Tianjin, Fujian.
Though the prestressed centrifugally precast square pile is taked reinforcement measure to the resistance to plucking pile extension, but still continue to use welding manner and since the stake with the stake be welded to connect after; Nature cooling 8-10min need be carried out and pile sinking can be continued; Wasted great amount of time, influenced the efficient of construction, many pile foundation construction personnel just continue pile sinking not according to welding requirements, after not waiting the weld cooling simultaneously; Reduce the quality of pile extension greatly, buried great potential safety hazard for whole engineering.Modes such as in order to fully play the extraction-resistant behavior of all kinds of concrete piles, the reliability that raising connects is guaranteed the safety of structure, and each side's appealing uplift pile employing machinery is sealed connect.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the problem that exists in the prior art, and a kind of mechanical connecting structure that is used for the precast square pile pile extension is provided, and that this mechanical connecting structure is made is simple, convenient and fast connection, dependable performance.The job practices of above-mentioned mechanical connecting structure also is provided simultaneously, this method convenient and quick construction.
In order to address the above problem technical scheme of the present invention is such:
A kind of mechanical connecting structure that is used for the precast square pile pile extension; The end plate that the end of the precast square pile of required butt joint is provided for docking; It is characterized in that; The side of end plate is provided with screw, and each other the end plate of butt joint is provided with the mechanical connection plate in the side, and the mechanical connection plate is connected through bolt on the screw of end plate side the end plate of butt joint is fixedly connected.
Said mechanical connection plate is provided with at least one locating hole and a plurality of adjustment hole, and bolt passes locating hole and adjustment hole screws in the screw of end plate side, and the diameter of adjustment hole is greater than the diameter of locating hole and screw.
Pass on the bolt of adjustment hole and also be provided with eccentric washer.
Each side of said end plate is provided with at least three screws.
Said end plate comprises a Plate with web, and the Plate with web middle part is provided with an end plate bore, and Plate with web also connects a pile ring cover.
Be evenly equipped with a plurality of reinforced holes on the said Plate with web, said reinforced hole comprises a stretch-draw hole, is arranged on the sliding muscle groove of stretch-draw hole sidewall, and stretch-draw hole side also is provided with main muscle pier nose hole on the Plate with web.
A kind of job practices that is used for precast square pile pile extension mechanical connecting structure may further comprise the steps:
(1) precast square pile single-unit stake manufacturing finishes and with behind the end plate installation in position, with supporting dormant bolt the thread on pile protection hoop, the preset nut is protected;
(2) according to structural requirement preparation and the matching used mechanical connection plate of end plate;
(3) during the pile extension contraposition; On two vertical planes of down joint stake, will be connected with corresponding screw in the lump with the mechanical connection plate with the steel plate that the end plate side is furnished with the connecting hole of same diameter; Mutually perpendicular two steel plates play positioning action; Be convenient to fixing between junction plate and the two end plates of other two directions of precast square pile, adopting screws with the supporting bolt of screw here is connected, treat that this two vertical planes connection finishes after; Two steel plates that will be used to locate again shirk, and the bolt of accomplishing other two vertical planes again connects.
The mechanical system pile extension is that Foundation Design is handled a kind of trend that connects, especially uplift pile engineering.The resistance to plucking precast square pile be a kind ofly be designed, novel building foundation pile that unit in charge of construction is progressively approved; Because the performance and the uplift pile bonding strength of uplift pile itself have determined this kind stake to be used for the feasibility of resistance to plucking engineering; This invention---a kind of mechanical connecting structure that is used for the precast square pile pile extension can reduce the mechanical connection point relatively, improves the reliability that connects; Reduce the potential safety hazard of Foundation Design, guarantee that further the safety of structure can improve the convenience of construction simultaneously.
