Abstract
The utility model discloses a pile hanging bracket, which comprises a central connecting member and a plurality of telescopic legs arranged along the circumference of the central connecting member. The telescopic legs are formed by outer legs and a plurality of inner legs; opposite leg walls of each outer leg and each inner leg are respectively provided with a pair of corresponding bolt connecting through holes, wherein the outer legs are respectively and radially welded on the central connecting member. The number of the telescopic legs is two, three, four, five, six, seven or eight; and the number of the inner legs is one, two or three. The pile hanging bracket has simple structure, quick construction and strong adaptability; the bracket can be provided with a plurality of the telescopic legs according to the requirements, the telescopic legs are matched with a cofferdam structure, so the construction requirements are met; the length of the telescopic legs is adjusted, thereby meeting the pile hanging requirements of steel protecting cylinders with different diameters; and the bracket has a detachable structure, can be used for a plurality of times and saves the cost.
Description
Technical field
The utility model relates to cofferdam steel casing extension pile driving construction equipment in a kind of bridge engineering.
Background technology
In the bridge engineering water in the foundation construction, the used steel casing of borehole wall-protection sometimes also will be as the pile foundation that supports the suspension box-cofferdam at home.The cofferdam is that support structure by a kind of being called " hanging pile bracket " is on the steel casing.Conventional hanging pile bracket is a welded construction, can hinder inserting of steel casing to beat because weld bracket in advance, so bracket can only weld at the scene, hanging pile bracket is cut off after construction is finished again.Field Welding and cut off complex process, difficult quality guarantee, and consuming time taking a lot of work influence the duration; Can not use after hanging pile bracket cuts off in addition, cause waste.
The utility model content
Technical problem to be solved in the utility model is to solve cofferdam steel casing to hang in the pile driving construction process hanging pile bracket field Welding and cut off complex process, poor welding quality, and consuming time taking a lot of work influences the duration, and can not use after cutting off, wasting problem.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of hanging pile bracket, comprise center connecting elements and some telescopic limbs along center connecting elements circle distribution, described telescopic limbs is formed by exopodite and some interior mutual plug-in mountings of limb, be respectively equipped with bolt connecting through hole one to one on the relative limb wall of each exopodite and Ge Nei limb, wherein exopodite is welded on the connecting elements of center respectively radially.
In the such scheme, described exopodite and interior limb are box girder structure, and the outer profile size of interior limb case beam is than the little 1～3mm of interior case overall size of exopodite case beam.
The quantity of described telescopic limbs is two, three, four, five, six, seven or eight.
In described the quantity of limb be one, two or three.
The utility model adopts hanging pile bracket as the braced structures of cofferdam structure on the steel casing, compares with the welded type hanging pile bracket, it is advantageous that:
(1) simple in structure, quick construction.This bracket does not have the building site weld seam, and demolition, installation are quick, and is time saving and energy saving.
(2) adaptive capacity is strong.Bracket can be provided with many telescopic limbs as required, matches with cofferdam structure, satisfies construction requirement; Adjust the length of telescopic limbs, can adapt to the extension stake requirement of different-diameter steel casing.
(3) economic and practical.Bracket is the reassembling type structure, can repeatedly fall usefulness, and under the enough prerequisite of supporting capacity, many limbs bracket can replace few limb bracket to use, and can replace the four limbs bracket to use such as eight limb brackets.
(4) workmanship is good.Hanging pile bracket is all made in factory, no building site weld seam, and quality is easy to guarantee.
Description of drawings
Fig. 1 is the utility model embodiment one structural representation;
Fig. 2 is along the half-sectional view of A-A line among Fig. 1;
Fig. 3 is the utility model embodiment two structural representations;
Fig. 4 is along the half-sectional view of B-B line among Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
Embodiment one,
As shown in Figure 1 and Figure 2, the utility model hanging pile bracket, comprise center connecting elements 13 and four telescopic limbs 11, telescopic limbs 11 is made up of interior limb 14 and exopodite 15, it is more smaller than the interior case overall size of exopodite case beam 15 that interior limb 14 and exopodite 15 are the outer profile size of box girder structure and interior limb case beam 14, general little 1～3mm.Interior limb 14 is inserted into the inside of exopodite 15 and can stretches out along the inwall of exopodite 15 or withdraw, and the sliding contact surface of the two must be smooth with convenient flexible.Inside and outside limb 14,15 behind the suit is drilled with bolt connecting through hole one to one respectively on the two relative limb wall, and also is provided with fabrication hole 16 on the case web of exopodite 14, so that bolt is installed.Four exopodites 15 are crosswise and are welded on respectively on the center connecting elements 13.Hanging pile bracket is under the state that bounces back fully, and its overall size must be less than the internal diameter of steel casing 12; Hanging pile bracket is under the state that stretches out fully, and its overall size must be greater than the external diameter of steel casing 12.
During use interior limb 14 is extracted out, be supported on the preformed hole on the steel casing 12, more inside and outside limb 14,15 is bolted to connection.
Embodiment two,
As shown in Figure 3, Figure 4, the difference of present embodiment and embodiment one is, the quantity of telescopic limbs 21 is eight, telescopic limbs 21 form by limb 26 in the limb 25 and second in the exopodite 24, first plug-in mounting successively and exopodite 24 with first, second in be drilled with bolt connecting through hole one to one respectively on the relative limb wall of limb.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.For example, the quantity of the telescopic limbs of the utility model hanging pile bracket is not limited to four or eight, also can be two, three, five, six, seven or other quantity, the quantity of interior limb be not limited to one, two or three, factually the border need be designed to a plurality of.
