Abstract
The present invention relates to a concrete stressed plate screw pile with one ore a plurality of stressed plates and triangular threads, and also relates to a forming device of the pile. The forming device is provided with a screw pipe with a rotary wing and a soil lifting screw pile with a rotary wing. When the device is used, the screw pipe and the soil lifting screw pile can be screwed simultaneously, and the soil is lifted out to finish forming pile holes. Before the screw pipe is screwed out, the screw pipe can be pressed and pulled to form stressed plate holes. Finally, the screw pipe is screwed out as the concrete is filled into the ground, and thus, the concrete stressed plate screw pile is formed. The present invention has the advantage that the pile has small size and large bearing capacity, and compared with an ordinary pile, the pile can save raw materials by more than 65%. The forming device has the advantages of simple structure and convenient operation.
Description
The present invention relates to the basis of a kind of building, bridge and the moulding tools of reinforced concrete pile.A kind of shaped device of concrete stressed plate screw pile particularly.
The piling of existing building, bridge, castinplace pile and electric industry vertical rod bearing capacity are little, a kind of forming method and equipment of concrete stake have been proposed in the US336760 patent for this reason, but the helix tube bottom does not have cutting edge in this equipment, and rotor on the helix tube and pipe jointing part position weak strength are fragile in addition.And the inventive method and equipment can be made into the concrete bearing peg that appearance can have a plurality of load dishes and screw thread, this pile capacity height, easy construction.
The object of the present invention is to provide a kind of appearance can have the shaped device of the concrete stake of load dish and screw thread, this device the concrete pile driving construction is speeded up and the life-span long.
The objective of the invention is to realize by following proposal:
Shaped device of the present invention comprises helix tube, and its appearance has rotor, and this rotor is the spiral dise knife, and the dise knife root is connected with the attached plate of spiral, and cutting edge is arranged at the bottom of helix tube, can finish the conveyor screw stake of large diameter.The soil lifting spiral pile of band rotor is housed in the above-mentioned in addition helix tube.
Advantage of the present invention is the easy construction of stake, formed pile capacity height.Shaped device is not fragile in addition.
Below in conjunction with embodiment and accompanying drawing the present invention is further described:
Fig. 1, concrete stressed plate screw pile schematic diagram for utilizing apparatus of the present invention to make.
Fig. 2, be concrete stressed plate screw pile shaped device lateral view
Fig. 3, be concrete stressed plate screw pile shaped device vertical view
The concrete stake that utilizes apparatus of the present invention to form includes the conveyor screw that cylinder 1 this cylinder 1 appearance has triangle thread 2.Be provided with a plurality of load dishes 3 along the cylinder vertical direction, establish load dish 3 along continuous straight runs and cylinder 1 and combine.
The shaped device of above-mentioned concrete stake comprises helix tube, and this helix tube bottom is provided with cutting edge 15, and helix tube is externally connected with spiral dise knife 17, and the dise knife root is connected with the attached plate 16 of spiral.
Can soil lifting spiral pile be arranged encapsulation in above-mentioned helix tube, this soil lifting spiral pile bottom is connected with a spiral dise knife 13 for the screw rod of awl point on this screw rod.
In the shaped device of this routine concrete stressed plate screw pile helix tube with carry native spiral apart from identical (also can be inequality), whole device is made of steel, the attached plate of spiral dise knife and spiral is made by welding.
When using this shaped device to carry out the construction of concrete stressed plate screw post, available same power screws in helix tube and soil lifting spiral pile underground., take out one time soil lifting spiral pile, thereby take earth in the helix tube out of enough once during the amount of fetching earth in the precession degree of depth.Limit precession like this, soil is carried on the limit, until reaching desired depth.For making the hole of load disk shape, before withdrawing from helix tube, helix tube is exerted pressure and pulling force, therefore under the effect of dise knife on the helix tube, form a symmetry and be compacted force-bearing disc hole (referring to Fig. 1).At this moment just can off the netly advance in the hole, pour into into the load dish precast reinforced, and along with the back-out of helix tube.Progressively concrete perfusion forms threaded cylinder.Meanwhile, also can in the process that helix tube screws out, continue to press, draw helix tube, make one or more force-bearing disc holes, and pour into out concrete bearing block according to the load needs on basis.When helix tube all screws out, can finish the reinforced concrete foundation stake of a screwed and load dish.
When using this shaped device to carry out electric industry vertical rod construction, can finish with said method and revolve the hole and make force-bearing disc hole, put into reinforcing bar, make the load dish, screw out helix tube again, put into electric pole at last, accomplish fluently the chuck reinforcing and just can finish.
The present invention has the following advantages:
1, the volume of concrete bearing block screw pile is little, and it is few to consume construction material, but loaded area is big, thereby with the common stake of equal bearing capacity relatively, can save a lot of building materials and man-hour, and can effectively improve the quality of soft basic unit and complicated basic unit, overcome the problem of immerge and uneven subsidence.
2, do pole-foundation with this stake, can reduce earth excavation, bar is with the strengthening quality height.
3, the shaped device of concrete bearing block screw pile is simple in structure, and is easy to operate, and fully guaranteed the realization of concrete bearing block screw pile.
Claims (2)
1, a kind of appearance has the shaped device of the concrete stake of load dish and screw thread, and it comprises helix tube, and its appearance has rotor, it is characterized in that this rotor is the spiral dise knife, and the dise knife root is connected to the attached plate of spiral, and cutting edge is arranged at the bottom of helix tube.
2, shaped device according to claim 1 is characterized in that being equipped with in the helix tube soil lifting spiral pile of being with rotor, and the bottom of this screw pile is the screw rod that the awl point is arranged, and is connected with a spiral dise knife on it.
