Description
Technical field
This utility model belongs to building field, a kind of miniature multi-column pier foundation stake with articulated joint.
Background technology
Mini pile refer generally to a footpath less than 400mm, slenderness ratio more than 30, use the Small Diameter Pile of the construction technologies such as boring and slip casing by pressure, because of advantages such as its load-carrying properties are good, construction equipment is simple, construction space is little, noise is little, being widely used in recent years in Transmission Tower-line line pole tower basis, particularly China's Coastal Areas soft soil foundation line project is built.
The miniature pile foundation of existing transmission line of electricity generally uses pile body reinforcing bar to extend into cushion cap, by pouring the consolidation of both realizations.But used environment and loading characteristic to be affected by transmission tower, in transmission line of electricity running, miniature multi-column pier foundation bears bigger horizontal loading, the pattern that stake has just connect with cushion cap makes pile body produce and bears bigger moment of flexure and cause pile body ratio of reinforcement height and uneconomical and be easily destroyed, the potential safety hazard bigger to the formation of top transmission tower.
Utility model content
The purpose of this utility model is that a kind of minimizing bending is developed in offer, improves the stress performance of stake, it is adaptable to the miniature multi-column pier foundation stake with articulated joint of existing pole and tower foundation engineering.
The technical solution realizing this utility model purpose is:
A kind of miniature multi-column pier foundation stake with articulated joint, including the ball pivot first half, ball pivot lower half, connecting bolt, anchor bar, pile body, the described ball pivot first half is provided with the spherical crown that convex is downward, center is provided with prebored hole, wherein the diameter of prebored hole is fixed with the top of the ball pivot first half be connected more than the diameter of connecting bolt screw rod, some anchor bar；Ball pivot lower half is provided with spill segment upwards, and center is provided with the screw corresponding with connecting bolt, and some anchor bars are fixed with the bottom of ball pivot lower half and are connected；Connecting bolt passes prebored hole, is tightened together with ball pivot lower half by the ball pivot first half, leaves gap between screw rod and the prebored hole hole wall of connecting bolt；The anchor bar of ball pivot lower half is fixed in pile body body.
This utility model compared with prior art, its remarkable advantage:
(1) this utility model solves, with the articulated manner of the miniature multi-column pier foundation stake of articulated joint, the problem that the bending caused because of consolidation is excessive, reduces the horizontal loading impact on pile foundation, is effectively increased miniature clump of piles base service life；
(2) compared to common buildings pile foundation, the general stress of a miniature clump of piles is less, facilitates views with the miniature multi-column pier foundation stake with articulated joint；
(3) two parts ball pivot is tightened up by connecting bolt by this utility model with the miniature multi-column pier foundation stake of articulated joint, simple to operate, and efficiency is high；
(4) this utility model is good with the miniature multi-column pier foundation stake hinge method stress performance of articulated joint, and power transmission is clear and definite, it is adaptable to transmission tower foundation engineering.
Below in conjunction with the accompanying drawings this utility model is described in further detail.

Detailed description of the invention
In conjunction with a kind of miniature multi-column pier foundation stake with articulated joint of Fig. 1-Fig. 3: this utility model, including the ball pivot first half 1, ball pivot lower half 2, connecting bolt 3, anchor bar 4, pile body 5, the described ball pivot first half 1 is provided with the spherical crown that convex is downward, center is provided with prebored hole 12, and prebored hole 12 diameter should meet the relevant regulations of " Construction of Steel Structure inspection of quality specification " (GB50205-2001).Wherein the diameter of prebored hole 12 is fixed with the top of the ball pivot first half 1 be connected more than the diameter of connecting bolt 3 screw rod, some anchor bar 4；Ball pivot lower half 2 is provided with spill segment upwards, and center is provided with the screw corresponding with connecting bolt 3, and some anchor bars 4 are fixed with the bottom of ball pivot lower half 2 and are connected；The ball pivot first half 1, through prebored hole 12, is tightened together with ball pivot lower half 2, leaves gap between screw rod and prebored hole 12 hole wall of connecting bolt 3 by connecting bolt 3；The anchor bar 4 of ball pivot lower half 2 is fixed in pile body 5 body.
Described pile body 5 tip edge is provided with some rubber blankets 10, it is simple to the active force in snubber contact face.
It is provided with politef slide plate 11 between the described ball pivot first half 1 and ball pivot lower half 2, reduces the friction between upper and lower ball pivot.
It is provided with ring-shaped rubber sealing ring 9 between the described ball pivot first half 1 and ball pivot lower half 2, plays the protective effect within ball pivot, extend its service life.
The described ball pivot first half 1 top pours a laminin concrete seven, forms the parcel to the ball pivot first half 1 and protects.
The described ball pivot first half 1 and ball pivot lower half 2 all use steel material to make.
