Abstract
The invention discloses a removable hanging pile bracket for construction of a hanging pile of a steel casing of a cofferdam, which comprises a central plate and a plurality of support legs. The central plate comprises a central sleeve, an upper end plate and a lower end plate, wherein the upper end plate and the lower end plate are welded on the peripheral surfaces of the upper end and the lower end of the central sleeve; and the support legs are respectively and uniformly arranged between the upper end plate and the lower end plate along the periphery of the central plate and are respectively hinged with the upper end plate and the lower end plate. When the removable hanging pile bracket is in the hanging state, the central plate is rotated to the position where the support plates are aligned at reserved holes in the steel casing, the support legs are pulled out from the reserved holes and are fastened to the central plate through bolts after adjustment and positioning, and construction can be carried out after the removable hanging pile bracket is installed. When the construction is completed, the bolts are removed, the bracket can be used in an inverted way, the efficiency of hanging pile construction can be increased, and the construction cost can be reduced.
Description
Technical field
The cofferdam steel casing that the present invention relates in the bridge engineering is hung the pile driving construction device, particularly relates to cofferdam steel casing extension pile driving construction and uses the reassembling type hanging pile bracket.
Background technology
The normal cofferdam steel casing extension pile driving construction device that adopts is constructed in the bridge engineering, and it is the field Welding structure that general at home steel casing is hung stake equipment, will hang stake equipment after the construction completion again and cut off.Field Welding with cut off complex process, consume the plenty of time, and welding quality is difficult for guaranteeing, influence the duration, in addition, hang and can not use after an equipment cuts off, cause waste.
Summary of the invention
Technical problem to be solved by this invention is to solve steel casing extension stake device context to weld and cut off, and the consumption time, influences the duration, and hangs and can not use wasting problem after stake equipment cuts off.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted provides a kind of cofferdam steel casing extension pile driving construction and uses the reassembling type hanging pile bracket; Comprise spider and a plurality of supporting leg, said spider comprises cylindrical central sleeve and is welded on the upper and lower end plate on this cylindrical central sleeve upper and lower end external peripheral surface; Said a plurality of supporting leg circumferentially is uniformly distributed with along spider respectively and is arranged between the upper and lower end plate and hinged with upper and lower end plate respectively.
In such scheme, be respectively equipped with many group bolt mounting holes on the upper and lower end plate, organize bolt mounting holes more and circumferentially be uniformly distributed with setting along spider respectively, be respectively equipped with on a plurality of supporting legs and the bolt mounting holes through holes one to one of organizing more.
In such scheme, supporting leg is that girder structure and cross section are I shape.
The present invention, preformed hole aligns on rotation spider to supporting leg and the steel casing hanging under the state, and supporting leg is extracted out from preformed hole, and it is fastening with supporting leg and spider that bolt is passed through in back, adjustment location, the completion of promptly constructing of hanging pile bracket installation procedure.
The present invention has following advantage:
A. single bracket is full welded unit, and assembly welding is good in advance before the extension stake, reduces the field Welding workload.
B. adopt bolt and hinged between each member of bracket, avoid field Welding, can add the quick draw pile driving construction.
C. after construction is accomplished, remove bolt, bracket can be used, and has reduced steel using amount.
D. simple in structure, be convenient to construction.
Description of drawings
Fig. 1 is a reassembling type hanging pile bracket assembling drawing (user mode);
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is a reassembling type hanging pile bracket dismounting sketch map (retracted state).
The specific embodiment
Below in conjunction with accompanying drawing the present invention is made detailed explanation.
As shown in Figure 1; The present invention includes spider 1 and a plurality of supporting legs 2; Said spider comprises cylindrical central sleeve and is welded on the upper and lower end plate on this cylindrical central sleeve upper and lower end external peripheral surface; Be respectively equipped with many group bolt mounting holes on the upper and lower end plate; Many group bolt mounting holes circumferentially are uniformly distributed with setting along spider respectively, are respectively equipped with on a plurality of supporting legs 2 and many group bolt mounting holes through holes one to one, and a plurality of supporting legs 2 circumferentially are uniformly distributed with along spider 1 respectively and are arranged between the upper and lower end plate and hinged through bearing pin 3 and upper and lower end plate respectively.
Supporting leg 2 is that girder structure and cross section are I shape; It circumferentially is laid with a plurality of reservation through holes steel casing 5 upper edges, cofferdam in same horizontal plane; Leave certain clearance between supporting leg 2 and the left and right inwall of reservation through hole; When this gap need guarantee spider 1 rotation, supporting leg 2 can be regained from reserve through hole smoothly, and was as shown in Figure 3.
In the present embodiment, the quantity of supporting leg is 4, and still, the present invention is not limited to 4 supporting legs, and according to the practice of construction needs, the quantity of supporting leg can be set to 3,6 or 8.
Practical implementation process of the present invention is following:
1, assembly welding supporting leg and spider: before hanging stake, welding and the postwelding of accomplishing supporting leg 2 and spider 1 each member in factory in advance polish work, confirm the number of supporting leg 2 according to the structure stress needs.
2, member spelling, integral hoisting: the supporting leg 2 that corner angle are polished is connected with spider 1 usefulness bearing pin 3, and be hinged state this moment between spider 1 and the supporting leg 2, and center of rotation dish 1 drives supporting leg 2 rotations, and supporting leg 2 rotates into state shown in Figure 3 around bearing pin 3 simultaneously.When hanging stake, the hanging pile bracket integral body after the assembly unit is hung in the steel casing 5.
3, positioning of rotating: preformed hole aligns on rotation spider 1 to supporting leg 2 and the steel casing hanging under the state; Supporting leg 2 is extracted out from the preformed hole of steel casing 5; Adjustment location back is fastening with supporting leg 2 and spider 1 through bolt 4, the completion of promptly constructing of hanging pile bracket installation procedure.
4, remove: after whole extension pile driving construction was accomplished, the lifting hanging pile bracket was removed bolt 4, and center of rotation dish 1 makes supporting leg 2 break away from steel casing preformed hole, can complete recovery hanging pile bracket.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under enlightenment of the present invention, making, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
