Clamping platform 7 outside be adjacent to, when securing member 3 connects two Hough parts 1, base 4 to moving near the direction of clamping platform 7 thus
The loop configuration making some Hough parts 1 be formed is set on the clamping platform 7 of two pile bodies 6 and makes two pile bodies 6 to realize fixing company
Connect.
Angle between clamping wall 5 and base 4 is between 100-130 °.Preferred version, between clamping wall 5 and base 4
Angle is 105 °.
The applicant studies through for many years, and combines building trade standard, it is contemplated that the end face of pile body 6 has certain thick
Rugosity and/or gradient, when two pile bodies 6 dock, it is impossible to ensure that the sticking part of two pile bodies 6 is proper with the axial line of pile body 6
Good vertical.It is true that have error (the namely axial line of pile body 6 and stake producing pile body and end face during prefabricated pile
The end face out of plumb of body 6), may result in two pile bodies central axis of two piles when docking not straight (axial line is misaligned),
Therefore to be encased inside pad in the joint of two piles i.e. both ends of the surface when pile extension, the central axis of two piles could be regulated,
Therefore just require attachment structure to allow both ends of the surface to also ensure that and will not be destroyed in the case of having gap.The application
People, finds through substantial amounts of test, the angle between the angle between domatic 8 and horizontal plane, and clamping wall 5 and base 4
Angle and coordinate pile body stress had and directly affect.
Atlas, external diameter 400-600mm is designed according to " being mechanically connected pretensioning prestressed concrete bamboo joint pile " 2013 Zhejiang G32
Pile body connect time, the gap of both ends of the surface is at positive and negative 5mm, requirement more than the 1600KN to be reached of pile body axial tension bearing capacity.
It has been found that the angle of the angle between angle and clamping wall 5 and the base 4 between domatic 8 and horizontal plane
Mutually meanwhile, it is capable to reach optimal fiting effect, shown in Figure 10, the gap between two pile bodies 6 is L, domatic 8 and level
Angle between face is α, and the angle between clamping wall 5 and base 4 is also α.Under indicate the relation between different L and α.
From the foregoing, it will be observed that when α is 130 °, maximum allowable L-value is 14.9mm, namely precision can when making for prefabricated pile
To reduce, but pile body axial tension bearing capacity is minimum, only 871.2KN, when when α is 100 °, and pile body axial tension bearing capacity
Up to 2342.2KN, maximum allowable L-value is 2.2mm, but it is higher that pile body is made required precision.When α is 105 °, maximum allowable
L-value is 4.9mm, and pile body axial tension bearing capacity is up to 2036.7KN, and meets and " be mechanically connected pretensioning prestressed concrete
Bamboo joint pile " 2013 Zhejiang G32 design atlas standard.Applicant further found that, when α is 105 °, it is simple to processing clamping wall 5 and base
4, accurate angle can be reached by milling, mechanization production can be realized, and when α is 100 °, milling cutter adds in clamping chamber 2
Work inconvenience, it is impossible to realize the requirement of the big production of mass.
Specific embodiment described herein is only to present invention spirit explanation for example.Technology neck belonging to the present invention
Described specific embodiment can be made various amendment or supplements or use similar mode to replace by the technical staff in territory
Generation, but without departing from the spirit of the present invention or surmount scope defined in appended claims.
Although the most more employing Hough part 1, contiguous block 1a, resigning hole 1b, connecting through hole 1c, bolt hole 1d, card
Connect chamber 2, securing member 3, base 4, clamping wall 5, pile body 6, clamping platform 7, the terms such as domatic 8, but be not precluded from using other term
Probability.Use these terms to be only used to more easily to describe and explain the essence of the present invention；It is construed as appointing
What a kind of additional restriction is all contrary with spirit of the present invention.
