Description
Technical field
A kind of stiffness body top and engineering pile single pile single-column cushion cap are the utility model is related to, it is more particularly to a kind of to carry joint bar
Fill the prefabricated cushion cap of core.
Background technology
In recent years, with the fast development of logistics, the construction of large-scale logistic storage is more and more, especially in East Coastal
Area.For logistic storage, it is high for the bearing requirements on first floor ground, typically to reach 30kPa and its more than, and deform
Control requires high, and total settling amount general control includes the TERM DEFORMATION control etc. in later stage within 100mm, but due to east
Coastal area soil property is relatively poor, and deep ＆ thick silt matter soil layer is much above 20m, and corresponding dealing with foundation scheme has become
It is particularly important, terrace processing how is effectively carried out, the especially control to duration and cost has become extremely crucial.A kind of new skill
Art starts progressively to promote the use of, i.e., using reinforcing body of the prefabricated high-strength stiffness body as the soil body, the conventional prestressing force of wall ratio
Pile tube is low, and corresponding quantity of reinforcement is relatively low, but due to its reliable in quality, is easy to construct, and in order that terrace load is more reliable
Ground is transferred in foundation soil, and expansion cushion cap is additionally arranged on stiffness body top.The cast-in-place mode of expansion cushion cap generally use makes, phase
The elapsed time and difficulty of construction answered are larger, and Jian Hua pile tube proposes a kind of prefabricated pile cover mode with reference to its stiffness body and made,
But fail the connection for effectively solving pile cover and cushion cap.
According to the pile tube atlas of the design concept of cushion cap and correlation, mainly upper load is more effectively transferred to
In stake, while the thickness of superstructure plate is also effectively reduced, stake is effectively divided the punching load of terrace plate or structural slab
Dissipate.Stake top is caused certain moment of flexure to be present in view of upper load inhomogeneities that may be present simultaneously.Therefore, in stake top portion
Dividing needs to carry out joint bar filling core, and stake top is strengthened.Therefore existing bearing platform construction technique, is generally divided into two steps, stake
The construction of tip cutting core segment, the welding of reinforcing bar on stake top end plate, then carries out the construction of cushion cap, and corresponding field operation is more,
And need to carry out a series of working procedures such as reinforcing bar colligation, installation form, casting concrete at the scene, so as to the engineering time compared with
It is long.The operation that corresponding quality will be limited by multiple teams and groups workers is horizontal (including the work such as bar bender, carpenter, bricklayer's), and holds
Platform has been constructed rear, it is necessary to which next process could be carried out by carrying out certain maintenance.Original technique integral construction time is longer, work
People's scope of operation is more, and the circulation material such as template can not be fully used, during bearing platform construction, the work of formwork reinforcement
Amount is simultaneously again bigger.

3rd, clear and cut in pile crown operation in protection soil layer, machinery should be avoided and manually between stake below design stake top plane
Native excessive turbulence and pile body is collided with.Avoid causing the skew of stake during installation platform.
The levelling device 13 includes nut 10 and adjustment bolt 11, and the nut 10 is welded in hollow pile or stiffness body 9
End plate 12 on, adjustment bolt 11 is bolted in nut 10, and the head of adjustment bolt 11 is hemispherical dome structure.
Because stake is in manufacturing process, it is understood that there may be uneven and the stake in work progress the perpendicularity of stake top end plate 12
Existing deviation, deviation caused by construction is possible is 400 (for the length of side of the diameter or hollow square pile of stiffness body or pile tube) * 1%
The deviation 2mm=6mm of+end plate 12, therefore when cushion cap is installed, ensure that the top surface of prefabricated cushion cap is horizontal as far as possible, by hollow
WELD NUTS 10 on the end plate 12 of stake or stiffness body 9, the height of nut 10 is 20mm, and the length of the screw rod of nut 10 is 20mm,
Be spirally connected bolt in nut 10, and bolt head is hemispherical dome structure, so as to thoroughly solve the problems, such as flatness, the screw rod rule of bolt
Lattice are 16mm, and bolt head is highly 5mm, by swivel bolt, so as to ensure bolt head height in 30mm ± 5mm models
It is adjusted in enclosing, so as to solve the prefabricated cushion cap top surface horizontal departure caused by the injustice of end plate 12 or construction deviation.
