Description
Technical field
The present invention relates to the MACHINERY JOINT in the prestressed concrete pipe pile construction in construction work, especially a kind of Prefabricated Reinforced Concrete Square Pile fast mechanical connector linkage.
Background technology
Prefabricated Reinforced Concrete Square Pile is because the advantage in its performance (is greater than pile tube with square pile external surface area under the concrete of cross section, and become the profile of square or many corner types, in soil layer, pile body periphery soil is larger than the circular coefficient of friction resistance with native angle of repose) in construction work pile foundation field, alternative pile tube is generally used gradually, be indispensable construction material, be widely used in the communal facilitys such as heavy construction, station, harbour, bridge.Traditional Prefabricated Reinforced Concrete Square Pile connects all to adopt manually welds, well-known artificial welding is a technical skilled worker of having relatively high expectations, several factors in welding process all can cause welding quality not reach technical requirements and directly affect square pile quality of connection, manually welds existing serious drawback major embodiment what time below:
A. weld interval long, approximately need 30 minutes at every turn.
B. in the rainy day, can not carry out welding procedure.
C. after welding, meet water generates and harden, easily produce rotten stake.
D. poor mechanical property, is not the whole end face welding of stake during due to welding two pile, and just at the edge of stake welding one circle, so be difficult to guarantee the pile extension performance after welding.
E. after welding, only 10% weld is carried out to carrying out flaw detection, all the other joints of 90% do not detect, and certainly exist hidden danger of quality.
For overcoming, above-mentionedly because adopting welding method to connect the drawback causing, fully play the extraction-resistant behavior of all kinds of concrete piles simultaneously, improve the reliability connecting, guarantee the safety of structure, be necessary to adopt the modes such as machinery is sealed to connect.Concrete pile mechanical connection manner mainly contains at present: eccentric lock compact form, thread connecting mode and bolt-type etc.All there is also complicated, partially long defect of engineering time of complicated structure, attended operation in above-mentioned connected mode, and above mechanical connection manner is only suitable for the connection of circular stake.As a kind of gear shaping formula pile tube mechanical connecting joint, the structure of this joint is by the default several pin holes of the end plate of joint up and down being connected pile tube, fastening spring is housed in hole, then with several latch alignment pins holes with dentation, connection has been installed, the unfavorable factor of its existence has: because of centering poor, site operation is inconvenient, and it is large that pile body verticality is controlled difficulty, and low strain detecting (being pile integrity detection) is difficult to up to standard.
Summary of the invention
The object of the invention is to the defect for prior art, design a kind of Contraction in Site that is beneficial to, efficiency is high, and cost is low, the Prefabricated Reinforced Concrete Square Pile fast mechanical connector linkage that bearing capacity of single pile is high.
The technical scheme that realizes the object of the invention is: a kind of Prefabricated Reinforced Concrete Square Pile fast mechanical connector linkage, it comprises the square bar cap that is fixedly installed on respectively upper and lower two joint square pile end surroundings, described linkage also comprises adapter sleeve, connecting axle and for the connection abaculus (being called again connecting pin) of fixed operating sleeve and connecting axle, described each adapter sleeve is fixedly installed in four peripheries of square bar cap, at each adapter sleeve center, offers connecting hole; Described connecting axle is installed between upper and lower two adapter sleeves, for saving up and down a vertical centering, connects into integral body; The shape of described each connecting axle and upper and lower two spliced shapes of connecting hole are suitable; On described each steel cap, adapter sleeve and connecting axle, all correspondence offers abaculus hole, and described connection abaculus embeds adapter sleeve and connecting axle by abaculus hole, makes pile body and connecting axle, adapter sleeve form integral body.
For better technique effect, technical characterictic of the present invention can also further be specially:
1, each adapter sleeve that is fixed on four peripheries of square bar cap described in position in the middle of side skirt edge in steel cap that is welded.
2, described connection abaculus is pyramidal structure, and its shape of cross section is rectangle or circle; Pyramidal structure is easier to manufacture, and is convenient to on-the-spot installation, and centering is good.
3, described adapter sleeve is cuboid or cylinder.
4, described connecting axle is pyramidal structure, and its shape of cross section is rectangle or circle; This shape pressure-bearing effect is the most desirable.
The precast concrete square pile fast mechanical connector linkage that the present invention realizes is according to the design feature of itself intrinsic member steel cap, through ingenious repacking, in the middle of steel cap surrounding skirtboard inner side, be welded with adapter sleeve, and offer respectively connecting hole being welded with above adapter sleeve position namely steel cap end plate plane, for connecting axle, work the locking effect that connects, in the surrounding skirtboard outside, adapter sleeve position that is welded, offer abaculus hole simultaneously, for connecting abaculus locking, form the stable connected mode that axial-radial interconnection is locked mutually.Its simple structure, greatly reduces cost of production, and has facilitated Contraction in Site, has improved production efficiency, makes quality more reliable.
Accompanying drawing explanation
Fig. 1 is a kind of precast concrete square pile fast mechanical connector linkage structural representation described in the embodiment of the present invention;
Fig. 2 is single square pile face linkage plan structure schematic diagram in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
As depicted in figs. 1 and 2, a fast mechanical connector linkage, it comprises the steel cap 1 that is arranged at respectively upper and lower two joint square pile 10 end surroundings, adapter sleeve 2, connecting axle 3 and for the connection abaculus 4 of fixed operating sleeve and connecting axle; Described adapter sleeve 2 is welded respectively in centre position, 1 four interior side skirt edges of steel cap, and adapter sleeve 2 centers offer connecting hole 21; Described connecting axle 3 is pyramidal structure, and its cross section is circular (figure slightly), and described connecting axle 3 is installed between upper and lower two adapter sleeves 2, for saving up and down square pile 10 vertical centerings, connects into integral body; The shape of described connecting axle 3 and two spliced shapes of connecting hole 21 are suitable; On described steel cap 1, adapter sleeve 2 and connecting axle 3, correspondence offers abaculus hole 41, described connection abaculus 4 embeds steel cap 1, adapter sleeve 2 and connecting axle 3 by abaculus hole 41, make pile body and connecting axle 3, adapter sleeve 2 form whole, described connection abaculus 4 cross sections are that beloid class is trapezoidal, and its narrow end embeds in connecting axle.
During construction, first this is reequiped and has been installed the Prefabricated Reinforced Concrete Square Pile of adapter sleeve and squeezed into one meter of left and right apart from ground, then connecting axle is inserted respectively in lower joint square pile end face connecting hole to embedding tight, the aligning connecting axle of the upper joint square pile of the adapter sleeve that is welded equally being sling is pressed into, and the abaculus hole of finally connection abaculus being squeezed into respectively to upper and lower two joint stake edges, surrounding is urgent.
