It not only can bear axial force and shearing force, but also can bear bending moment, so that it can raise working efficiency.
Description
The present invention relates to building field preformed pile link, specifically a kind of assembled level-adjustable rigid joint device for precast pile.
In building field, traditional preformed pile steel joint mainly adopts angle steel joint (first cap or second cap), and it is vertically to weld with angle steel, and upper and lower stake is connected as a single entity.There are following problems in this connection:
1, because the hypomere stake has certain inclination in pile driving process, even verticality is controlled at standard
Require 1% in, hypomere stake top surface also has 0.4-0.45cm (400 * 400mm stake
With 450 * 450mm stake) the discrepancy in elevation.As verticality＞1%, then the stake top surface the discrepancy in elevation
Bigger.And because pile cutoff making king-pile top surface can not be fully perpendicular to the pile body center
Line, when epimere stake when stake is connected with hypomere, upper and lower two sections stake connecting portions all have not
With the space of degree, certainly will cause two sections stake junctions is local compression.Construction for this reason
In the normal steel sheet that adopts level up as cushion block, but the part of going up stake and a following connecting portion is subjected to
The problem that the stress that pressure condition causes is concentrated does not solve, especially prefabricated at high tonnage
Often cause the concrete of connecting portion crushed and the vertical crack of main muscle longitudinally occurs in the stake,
Thereby influence pile quality.In big or small strain detecting, adopt this kind joint, at joint
The stronger back wave of the normal appearance in place finally influences workmanship.
2, the angle steel joint vertical position welding fusion length of upper and lower two sections stakes is the on-the-spot needs of 32m (first cap)
A large amount of pile extension time, and be difficult for welding, the stressing conditions that causes designing can't realize,
Influence workmanship.
3, when pile body is in the layer of sand, pile extension is chronic, and will to cause continuing pile sinking very difficult.
4, because preformed pile is the stake type of compacted property, often cause soil body protuberance, add above reason,
Thereby stake separates the floating stake accident that causes with hypomere easily to cause the epimere stake.
CN94203075.3 discloses the preformed pile syndeton that a kind of name is called " sleeve welding pile joint ", though this structure has solved the subject matter that above-mentioned traditional structure exists, its bending resistance square ability is very poor.Because the attachment weld of the upper and lower two sections stakes of this structure is side seam, in fact this joint can only bear axial force and shearing, moment of flexure can not be born and maybe less moment of flexure can only be born, be equivalent to an articulated joint, this actual forced status with stake is not inconsistent, stressed more unfavorable when especially pile joint is in the soft layer, therefore, its restricted application.
The objective of the invention is in order to solve the problem that the above-mentioned background technology exists, propose a kind ofly both can bear axial force and shearing, can bear the assembled level-adjustable rigid joint device for precast pile of moment of flexure again, make it can satisfy the actual loading requirement of pile body fully, improve work efficiency, and be easy to leveling two pile joint end faces.
At the foregoing invention purpose, the present invention adopts following technical scheme: a kind of assembled level-adjustable rigid joint device for precast pile, going up cap by following that is embedded in down the stake top forms with a upper pile and lower cap that is embedded in the stake bottom, there is the groove that can be embedded by upper pile and lower cap on described following top of going up cap, its special character is to have breach on the sidewall of described groove, the vertical edges of this breach and top cross edge weld with the upper pile and lower cap corresponding position respectively, and form rigid joint device.
The present invention has drawn the advantage of two kinds of steel joints in the background technology, and its weak point is improved, and it has following advantage:
1) these piecing devices are provided with the about 30mm height of groove that can adorn sulphide mastic, because sulphur glue
Mud (in several minutes) before cooling has certain fluidity, sulphide mastic is injected this is recessed
In the groove, high-ranking officers' epimere stake is just in time immediately inserted among the joint, and exerts pressure, thereby
Can play the leveling effect in the junction of upper and lower two sections stakes, unnecessary sulphide mastic promptly
Groove overfills.It has solved and has easily produced local pressure in the preformed pile angle steel joint, and causing should
Power is concentrated, and finally influences the problem of workmanship.These piecing devices on technology to improving
The integrality of pile body provides guarantee.
2) these piecing devices directly are embedded in the integral installation that is connected to of the top of hypomere stake and epimere stake
Join formula, and the connection of upper and lower two sections stakes is mainly vertical position welding, and both is aided with side seam
Can bear a power, shearing and also can bear moment of flexure, be rigid joint, stress performance is good,
In full accord with the stress of stake, solved sleeve welding pile joint and be articulated joint
Problem promptly can only be born a power and shearing, can not bear moment of flexure and maybe can only bear less curved
The problem of square.
3) because above-mentioned two reasons, significantly reduced the field Welding amount (lack than the angle steel joint, with
Sleeve welding pile joint is close), a sight work efficiency is greatly improved.
4) steel using amount is minimum in three kinds of joints, and low price, and the good market competitiveness is arranged.
Below in conjunction with the accompanying drawing illustrated embodiment, describe the present invention in detail.
