Description
Technical field
The utility model is related to building foundation field, especially a kind of bolted precast square pile.
Background technology
The popularization of fast development and building pile foundation basis with urban construction, concrete prefabricated square pile is with its construction letter
Single, quick, economic the advantages of, especially widely applied in the soft southern area of soil property；But concrete prefabricated square pile
Jointing number, strength of joint and the long limitation of stake between the problem of using equally existing many, such as stake and stake and influence
Resistance to compression and anti-pulling capacity performance etc.；
Current concrete prefabricated square pile jointing is generally using welding, flange connection and sulphide mastic connection three
Kind.Welding connection is welded mainly by the pre-buried steel plate of subcontracting process and stake end, by weld seam shearing strength undertake above and below stake it
Between withdrawal resistance, but its weldquality is difficult to ensure that, workman's welding needs certain time, and stake is then easily caused too long and is difficult to again
The soil body is squeezed into, and welding angle steel bag can produce unnecessary frictional resistance in pile body periphery during pile body is pushed；Flange is connected
Being tensed by ring flange with bolt makes it combine closely, and has preferable intensity and compactness, application is wider, but flange is connected
Soon it can not assemble and unload, manufacturing cost is higher；Sulphide mastic connection belongs between end reserved steel bar and concrete
Anchor method, and pour into a kind of chill material of thermoplastic and reach certain adhesion strength, it has the disadvantage pile joint by uplift force
Easily disengage, extraction-resistant behavior is weaker.
The intensity effect of the bearing capacity of single pile of concrete prefabricated square pile not only by pile body in itself, is also carried by foundation soil
Power, which includes collateral resistance and end resistance, to be influenceed.In Wenzhou, Ningbo, Shanghai etc., southern soft clay area soil property is poor, building pile foundation basis
Long stake or ultra-long pile are used mostly, because concrete prefabricated square pile is by jointing number and the long limitation of stake, once foundation bearing
Power is not enough, and pile body resistance to compression and anti-pulling capacity can not meet design requirement, so as to have to abandon precast square pile using other
Pile-type.
Utility model content
In order to overcome the shortcomings of background technology, the utility model provides a kind of bolted precast square pile, not only with reliability
Connection, and higher resistance to compression and anti-pulling capacity can be provided in soft soil foundation, and it is quick and convenient to construct, economic sexual valence
Than high.
The technical scheme that the utility model is used：A kind of bolted precast square pile, including first section prefabricated pile, minor details are prefabricated
Stake, the first connection frame, the second connection frame, bolt, nut；The first connection frame or second is fixedly installed in the first section prefabricated pile upper end
Connect frame；The minor details prefabricated pile lower end is correspondingly arranged the second connection frame or the first connection frame；The first connection frame can be inserted
Second connects inframe, and its lateral wall fits with the second madial wall for being connected frame, and the first connection frame, second connect frame
Side wall is correspondingly provided with some through holes, and the bolt can be through the first connection frame through hole corresponding with the second connection frame, and leads to
Nut is crossed to fix；Length identical Grouting Pipe with itself, the first section are additionally provided with the first section prefabricated pile, minor details prefabricated pile
Prefabricated pile and the mutually corresponding connection of the Grouting Pipe in minor details prefabricated pile.
Some middle node prefabricated piles, the middle node prefabricated pile one are provided between the first section prefabricated pile and minor details prefabricated pile
End is internally provided with Grouting Pipe provided with the first connection frame, the other end provided with the second connection frame；The first section prefabricated pile, middle node
It is connected between prefabricated pile, minor details prefabricated pile by the first connection frame, the second connection frame, and its Grouting Pipe and head sections are prefabricated
Grouting Pipe in stake, minor details prefabricated pile mutually corresponds to connection.
Each described Grouting Pipe is respectively placed in the center position of first section prefabricated pile, minor details prefabricated pile, middle node prefabricated pile
Put.
The first connection frame is connected frame with second and is square structure.
Every side side wall that the first connection frame is connected frame with second is equipped with 3 through holes.
The first connection frame, the second connection outer frame surface are also coated with anticorrosive coating.
The beneficial effects of the utility model are：
1st, structure type is simple, and factory is easy to make, and batch production can be achieved；
2nd, it is bolted, attachment structure form simple stress clearly, can bear larger withdrawal resistance, and use in theory
Steel amount is few, produces cheap, economic advantages are obvious；
3rd, it is bolted, the joint between stake and stake and continuous injection stake can be connected within a short period of time
Base, speed of application is very fast, it is to avoid lower section stake, which is placed in soil, to be difficult to push too long；
4th, by grouting and reinforcing stake end and stake side foundation soil, bearing capacity of pile tip and pile side friction is improved, can be held in theory
By that can make after larger resistance to compression and anti-pulling capacity, and slip casting at full pile joint, connection is integral, and strength performance is outstanding；
5th, the area such as south is solved because soil property is soft and uses the pile foundation of long stake or ultra-long pile, it is wider using scope.
