Description
Technical field
It is especially a kind of the present invention relates to the MACHINERY JOINT in the prestressed concrete pipe pile construction in architectural engineering
Prefabricated Reinforced Concrete Square Pile fast mechanical connector attachment means.
Background technology
Prefabricated Reinforced Concrete Square Pile is due to the advantage in its performance（It is more than pipe with square pile external surface area under the concrete of section
Stake, and into the profile of square or more corner types, the angle of repose of pile body periphery soil and soil is bigger than the coefficient of friction resistance of circle in soil layer）
Pile tube is gradually substituted in architectural engineering pile foundation field generally to be used, is indispensable construction material, extensively should
For in the communal facilitys such as heavy construction, station, harbour, bridge.Traditional Prefabricated Reinforced Concrete Square Pile connection all uses people
Work is welded, it is known that human weld is the higher skilled worker of a technical requirement, the several factors in welding process are all
Welding quality can be caused not reach technical requirements and directly affect square pile quality of connection, the serious shortcomings master present in human weld
Embody it is following some：
A. weld interval is grown, and about needs every time 30 minutes.
B. welding procedure can not be carried out in the rainy day.
C. water is met after welding and is produced and is hardened, is also easy to produce rotten stake.
D. poor mechanical property, due to during two pile of welding not being the whole end face welding of stake, and simply welded at the edge of stake
A circle is connect, so being difficult to ensure that the pile extension performance after welding.
E. carrying out flaw detection only is carried out to 10% weld after welding, remaining 90% joint is not detected, certainly existed
Hidden danger of quality.
It is above-mentioned because caused by using welding method connection the drawbacks of to overcome, while fully play the anti-of all kinds of concrete-piles
Performance is pulled out, improves the reliability of connection, it is ensured that the security of structures, it is necessary to is attached using the machinery mode such as sealed.
Concrete-pile mechanical connection manner mainly has at present：Eccentric lock compact form, thread connecting mode and bolt-type etc..Above-mentioned connected mode
The defects of structure is more complicated, attended operation is also complicated, the engineering time is partially long be present, and above mechanical connection manner is suitable only for
In the connection of circular stake.Such as a kind of gear shaping formula pile tube mechanical connecting joint, the construction of the joint is by connected pile tube
Section end plate presets several pin holes up and down, and hole is built with fastening spring, then with several latch alignment pins holes with dentation
Installed to complete to connect, its existing unfavorable factor has：Because centering is poor, site operation is inconvenient, pile body perpendicularity control
Difficulty processed is big, low strain integrity testing（That is pile integrity detection）It is difficult to up to standard.
The content of the invention
The defects of it is an object of the invention to for prior art, design it is a kind of be beneficial to Contraction in Site, efficiency high,
Cost is low, the high Prefabricated Reinforced Concrete Square Pile fast mechanical connector attachment means of bearing capacity of single pile.
Realizing the technical scheme of the object of the invention is：A kind of Prefabricated Reinforced Concrete Square Pile fast mechanical connector connection dress
Put, it includes the square bar cap for being fixedly installed on upper and lower two section square piles end surrounding respectively, and the attachment means also include connection
Set, connecting shaft and for fixed operating sleeve and the connection abaculus of connecting shaft（Also known as connecting pin）, each adapter sleeve consolidates
Dingan County is loaded on four peripheries of square bar cap, and connecting hole is offered at each adapter sleeve center；The connecting shaft is installed on upper and lower
It is integral for the connection of stake vertical centering will to be saved up and down between two adapter sleeves；The shape and upper and lower two of each connecting shaft
The individual spliced shape of connecting hole is adapted；It is all corresponding in each steel cap, adapter sleeve and connecting shaft to offer abaculus hole,
The connection abaculus is embedded in adapter sleeve and connecting shaft by abaculus hole, pile body and connecting shaft, adapter sleeve is formed entirety.
For superior technique effect, technical characteristic of the invention can also be specially further：
1st, each adapter sleeve for being fixed on four peripheries of square bar cap is welded in steel cap among side skirt edge
Position.
2nd, the connection abaculus is pyramidal structure, and its shape of cross section is rectangle or circle；Pyramidal structure is easily manufactured,
It is easy to in-site installation, centering is good.
3rd, the adapter sleeve is cuboid or cylinder.
4th, the connecting shaft is pyramidal structure, and its shape of cross section is rectangle or circle；This shape pressure-bearing effect is most managed
Think.
The precast concrete square pile fast mechanical connector attachment means that the present invention realizes are according to itself intrinsic component steel
The design feature of cap, it is middle on the inside of steel cap surrounding skirtboard to be welded with adapter sleeve by ingenious repacking, and it is being welded with adapter sleeve position
Top i.e. steel cap end plate plane open up connecting hole respectively, play connection locking for connecting shaft, while in the adapter sleeve that is welded
Abaculus hole is opened up on the outside of the surrounding skirtboard of position, for connection abaculus locking, forms the stabilization that axial-radial interconnection is mutually locked
Connected mode.Its simple structure, greatly reduces production cost, and facilitates Contraction in Site, improves production effect
Rate, make quality relatively reliable.
Brief description of the drawings
Fig. 1 is a kind of precast concrete square pile fast mechanical connector attachment means structural representation described in the embodiment of the present invention
Figure；
Fig. 2 is single square pile face attachment means overlooking the structure diagram in Fig. 1.
Embodiment
The present invention is described further below in conjunction with accompanying drawing.
