The pile tip connecting device is conveniently welded, tightness is improved, the tensile strength of connection of the two piles is effectively improved, cost is saved, and connection is safe and reliable.
Description
Technical field
The utility model relates to a kind of stake end connection device of prestressed concrete pipe pile/square pile, belongs to Construction Technology field.
Background technology
It is high that prestressed concrete pipe pile/square pile has vertical bearing capacity of single pile, and batch production is produced, and pile quality is convenient to control and is stable, and economy and compliance are good, the advantages such as easy construction.Be widely used in as vertical pressure bearing pile in the engineerings such as industrial and civilian multi-rise building, field of traffic, airport, harbour, harbour, municipal administration.Prestressed concrete pipe pile has obtained application to a certain degree as vertically pulling-resistant stake during the course because of factors such as its good economy performance, quick construction in recent years, lost efficacy because contact connectivity problem causes prestressed concrete pipe pile/square pile resistance to plucking, caused the accidents resulting from poor quality of projects such as some basement bottom board floatings.Domestic to pile tube method of attachment done some research work, there are at present mechanical fast thread connection, the connection of novel Quick mechanical, clip mechanical connection, mechanical engagement to connect, these methods of attachment all, because machining accuracy is higher, difficulty of construction is large, the more high factor of cost, are subject to certain limitation in engineering construction.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and the stake end connection device that a kind of simple to operate, easy construction, welding difficulty are little, connect reliable prestressed concrete pipe pile/square pile is provided.
In order to solve above technical problem, the utility model provides a kind of stake end connection device of prestressed concrete pipe pile/square pile, be connected between joint stake and the stake of lower joint, described linkage comprises two pile protection hoops, two pile end plates and at least six junction plates, the thickness of two pile protection hoops is 6.0 ~ 12.0mm, the end that is socketed on respectively joint stake and lower joint stake, two pile end plates are fixedly installed on respectively the top of two pile protection hoops, and described junction plate is radially welded on described pile protection hoop uniformly.
Being further defined to of technical solutions of the utility model, in the time that the stake footpath of described pile tube/square pile is less than or equal to 700mm, the thickness of described pile protection hoop is 6.0 ~ 8.0mm.
Further, in the time that the stake footpath of described pile tube/square pile is more than or equal to 800mm, the thickness of described pile protection hoop is 10.0 ~ 12.0mm.
Further, described junction plate is strip plate, and plate is long is 24cm, and plate is wide is 8cm, thickness 6.0 ~ 12.0mm.
Further, the junction plate of prestressed concrete pipe pile is circular arc strip plate, and the diameter of described circular arc strip plate is identical with the external diameter of corresponding pile tube; The junction plate of prestressed concrete square pile is rectangle strip plate.
Further, the number of described junction plate is 6 ~ 12.
The beneficial effects of the utility model are: the stake end connection device of the disclosed a kind of prestressed concrete pipe pile/square pile of the utility model, pile protection hoop thickness is adjusted to 6 ~ 12mm, make easy to process, adopt junction plate and pile protection hoop to weld, two joint stakes are reliably connected, simple to operate, easy construction, welding difficulty are little, improve safety, meanwhile, cost is lower, and economic performance is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the stake end connection device of prestressed concrete pipe pile described in the utility model;
Fig. 2 is the top view of the stake end connection device of prestressed concrete pipe pile described in the utility model.
The specific embodiment
The stake end connection device of a kind of prestressed concrete pipe pile that the present embodiment provides, be connected between joint stake 4 and lower joint stake 5, its structural representation as shown in Figure 1, top view as shown in Figure 2, linkage comprises at least two pile protection hoops 2, two pile end plates 3 and at least six junction plates 1, in the present embodiment, adopt 6 ~ 12 junction plates 1, concrete quantity according to pipe pile footpath, stake the composite factor such as long and single pile tension bearing capacity determine.
Two pile end plates 3 adopt and the arc plate of pile tube external diameter with diameter, are fixedly installed on respectively the top of two pile protection hoops 2.
In the time that the stake footpath of described pile tube is less than or equal to 700mm, the thickness of described pile protection hoop 2 is 6.0 ~ 8.0mm.In the time that the stake footpath of described pile tube is more than or equal to 800mm, the thickness of described pile protection hoop 2 is 10.0 ~ 12.0mm.In the present embodiment, the stake footpath of pile tube is 500mm, and the thickness of pile protection hoop 2 is 8.0mm.
The linkage of the present embodiment only need increase junction plate welding in pile tube is manufactured middle adjustment pile protection hoop 2 steel plate thickness and constructed.Calculate uplift pile connected node as an example of 500 pile tubes example and increase expense, pile protection hoop increases steel plate materials 5x3.14x(0.08-0.015) 1.5x7.8=11.94KG, junction plate (by 8) steel plate materials 2.4x0.8x0.08x7.8x8=9.58KG, a connected node increases steel plate materials 11.94x2+9.58=33.46KG, consider the construction factors such as processing, welding, steel plate calculates by 7 yuan/KG, costs altogether and uses 33.46x7=234.22 unit, is greatly better than other types uplift pile.
The stake end connection device of a kind of prestressed concrete square pile that the present embodiment provides, its primary structure and parameter are similar to embodiment 1, difference is: prestressed concrete square pile junction plate 1 is rectangle vertical bar plate, and the stake footpath of square pile is 800mm, and the thickness of pile protection hoop 2 is 10.0mm.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
