State concrete meaning of the term in the invention.
Below with reference to embodiment come the present invention will be described in detail create.
A kind of device for overlength pile foundation large-tonnage steel muscle cage decentralization spreading, as shown in Figure 1, including annular gantry 1, edge
The annular gantry is radially provided with several notches 2, and each notch 2 is uniformly arranged using annular gantry center as the center of circle, and each institute
It states and is equipped with bolt 3 in notch；The annular gantry includes docking be fixed together multiple seperated 8 by connector 4；It is each
Suspension centre 5 is equipped on fission 8.Each seperated common assembling constitutes annular gantry, realizes the effect of fixed steel bars cage.
General notch is uniformly arranged 6, i.e., the bolt being uniformly arranged with 6 annulars, device to hole is interior to complete decentralization reinforcing bar
Cage is fixed temporarily, and fixed point is more, reduces the requirement to bolt rigidity, while bolt is made of vertical steel plate, is realized
The reasonable utilization of material stiffness；The annular gantry of annular gantry increases the contact area with basis, and reducing foundation bearing capacity needs
The stability that annular gantry is increased while asking, effectively prevent steel reinforcement cage to tilt.
Above-mentioned suspension centre is the hanging ring being weldingly fixed in annular gantry, or the lifting hole(eyelet) being provided in annular gantry.Benefit
With hanging device, it can facilitate, smoothly sling annular gantry, also can easily sling fission when assembling annular gantry.
Above-mentioned bolt includes the shank 6 being threaded through in notch, is in the part on the outside of annular gantry in shank and is equipped with adjustment
Part 7.Notch internal diameter is generally 3-5mm bigger than shank outer diameter, facilitates the adjustment of bolt, since bolt and steel reinforcement cage are not necessarily to accurately admittedly
Fixed or fastening, plug pin lengths are longer, and both ends stretch out in annular gantry (when contacting the locking to steel reinforcement cage, on the inside of bolt respectively
Also annular gantry inner wall can not be protruded from), therefore, when locking steel reinforcement cage, annular gantry is stretched out at bolt both ends respectively, so,
Bolt can radially be adjusted without departing from notch along annular gantry.
In general, above-mentioned adjustment part can be using the adjusting nut that shank is in annular gantry lateral ends be screwed in, it can also
To use other adjustment parts, as long as can be realized the adjustment to shank, the radial direction that can adjust shank along annular gantry is inserted
Enter, fixed steel bars cage；Also adjustable shank releases the limit to steel reinforcement cage from steel reinforcement cage " extraction ".The present apparatus can be convenient
Bolt is adjusted on the outside of annular hanger, very convenient, quick, labor intensity of workers is few, and difficulty is low.
In an optional embodiment, stablize as shown in Fig. 2, can be arranged in the inside that shank is in annular hanger
Part 9 guarantees to be influenced when shank will not be because of installation by factors such as annular gantry inclinations, and is detached from notch, leads to operation difficulty
It increases, or even can not occur the case where limit steel bar cage.
Specifically, stabilizing member can protrude into annular using the nut being screwed on shank by adjusting part adjustment shank
When length on the inside of rack, cooperation screws stabilizing member (nut) and can ensure that shank without departing from notch, and use is reliable and stable.It needs
It is noted that since using nut, as stabilizing member, when adjusting shank, only the nut need to be pulled using tools such as spanners, i.e.,
Shank can be adjusted by the adjustment part (such as adjusting nut) on the outside of annular hanger.
Above-mentioned annular gantry is divided into 2-4 fission.Bolt generally can be used in above-mentioned connector.Two is seperated to after just, leads to
It crosses bolt to be fixedly connected, realizes docking, by each seperated entire annular gantry of composition.Particularly with large-tonnage steel reinforcement cage, very just
Just it operates, annular gantry is designed using modular structure, and operation difficulty when reducing fixed large-tonnage steel reinforcement cage alleviates work
People's amount of labour, improves production efficiency.
Construction procedure is as follows:
1, using lifting appliance, complete the assembling of annular gantry；
2, realize the accurate positioning of annular gantry, it is ensured that annular gantry center is overlapped with hole location center.
3, bolt is mounted in annular gantry notch, open state is at.
4, lifting steel reinforcement cage is transferred, and decentralization pushes bolt, be at closed state to temporary holding location is needed,
Complete the temporary locking of steel reinforcement cage.
5, it lifts next section steel reinforcement cage and carries out spreading, after completing spreading, lift by crane whole reinforcement cage, extract bolt and be at
Open state carries out steel reinforcement cage decentralization.
6, step 3-5 is repeated, steel reinforcement cage decentralization is completed.
7, after completing pile foundation concrete construction, annular gantry is disassembled, transport to next hole location.
The invention structure is simple, and design rationally, is fixed using the bolt and steel reinforcement cage that are uniformly arranged along annular gantry,
Increase device and basis contact area, realize be fixed temporarily in overlength pile foundation large-tonnage steel muscle cage decentralization process it is quick
Change, summary.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
