The applicant passes through to be studied for many years, and combines building trade standard, it is contemplated that the end face of pile body 6 has centainly thick
Rugosity and/or gradient, when two pile bodies 6 dock, the axial line that not can guarantee the sticking part and pile body 6 of two pile bodies 6 is proper
It is good vertical.In fact, pile body and end face have error (the namely axial line of pile body 6 and stake during producing prefabricated pile
The end face out of plumb of body 6), the central axis that will lead to two pile bodies, two piles in docking is not straight (axial line is not overlapped),
Therefore both ends of the surface it to be encased inside gasket at the docking of two piles in pile extension, is just adjustable the central axis of two piles,
Therefore connection structure is required to also ensure that and will not be destroyed in the case where allowing both ends of the surface to have gap.The application
People, by largely testing discovery, angle between angle between slope surface 8 and horizontal plane, and clamping wall 5 and pedestal 4
Angle and cooperation, which have pile body stress, to be directly affected.
Atlas, outer diameter 400-600mm are designed according to " mechanical connection pretensioning prestressed concrete bamboo joint pile " 2013 Zhejiang G32
Pile body connection when, in positive and negative 5mm, the requirement of pile body axial tension bearing capacity will reach 1600KN or more in the gap of both ends of the surface.
It has been found that when the angle of the angle between the angle and clamping wall 5 and pedestal 4 between slope surface 8 and horizontal plane
Mutually meanwhile, it is capable to reach optimal fiting effect, as shown in connection with fig. 10, the gap between two pile bodies 6 is L, slope surface 8 and level
Angle between face is α, and the angle being clamped between wall 5 and pedestal 4 is also α.The following table shows the relationships between different L and α.
From the foregoing, it will be observed that maximum allowable L value is 14.9mm, that is, precision can in production for prefabricated pile when α is 130 °
To reduce, but pile body axial tension bearing capacity is minimum, only 871.2KN, when α is 100 °, pile body axial tension bearing capacity
Up to 2342.2KN, maximum allowable L value is 2.2mm, but higher to pile body production required precision.It is maximum allowable when α is 105 °
L value is 4.9mm, and pile body axial tension bearing capacity meets " mechanical connection pretensioning prestressed concrete up to 2036.7KN
Bamboo joint pile " 2013 Zhejiang G32 design atlas standard.Applicant further found that when α is 105 °, clamping wall 5 and pedestal easy to process
4, accurate angle can achieve by milling, be able to achieve mechanization production, and when α is 100 °, milling cutter adds in clamping chamber 2
Work is inconvenient, cannot achieve the requirement of mass mass production.
