The mechanical fast connector connecting device has the advantages of facilitating field construction and being efficient, low in cost and high in single-pile bearing capacity.
Description
Technical field
The utility model 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 mechanical mode such as 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 the also defect partially grown of complicated, 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.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 inconvenience, pile body verticality control difficulty is large, and low strain detecting (being pile integrity detection) is difficult to up to standard.
Summary of the invention
The purpose of this utility model is the defect for prior art, designs one and is beneficial to Contraction in Site, and 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 utility model object 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 the connection abaculus (being called again connecting pin) for 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 entirety; 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 entirety.
For better technique effect, technical characterictic of the present utility model can also further be specially:
1, the each adapter sleeve that is fixed on four peripheries of square bar cap described in the 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 utility model is realized 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.
