Abstract

The utility model relates to special-purpose construction foundation engineering concrete tube pile module, which includes a module core, an upper module and a lower module; the upper module and the lower module are arranged at the module core. A waved concave and convex rib groove are longitudinally arranged inside of the upper and lower cavities; the space between the concave rib groove in the waved concave and convex rib groove is provided with one or two or more convex rib grooves, which is communicated with the convex rib groove in the waved concave and convex rib groove. The device has the advantages that the design of tube pile module inner wall waved rib groove and the waved rib groove longitudinal rib groove can not only effectively expend and improve the loading capability of the tube pile of the support area of the formed tube pile, but also eliminate the defect of cracking of the tube pile wall due to uneven forcing at the joint of the tube pile wall and the convex rib to ensure the quality of the formed tube pile and is convenient for stripping.

Description

Waveform is indulged muscle pile tube mould

Technical field:

The utility model relates to a kind of building foundation engineering concrete special pile tube mould, belongs to concrete pipe pile mould and makes the field.

Background technology:

Granted publication CN 2712587y, title " ring shape pile for prestressed pipe punching block ", it is semi-circular with stubborn (button) the tight main body punching block of securing member that this utility model ring shape pile for prestressed pipe punching block includes two block length strips, the every interval 1～4m of main body punching block, it is the annular recess of right-angled trapezium or nearly right-angled trapezium or isosceles trapezoid that one sliver transvers section is arranged, long 5～the 40cm of groove cross section four edges, in annular recess and main body punching block junction surface and annular recess two corner angle partly or all establish the R angle.Its weak point: the rod iron in the special-shaped pile tube of this ring shape pile for prestressed pipe punching block formed thereby is between pile tube is haled tube wall that internal stress that the back that is shaped produced acts directly on pile tube and protruding ring, because the thickness of ring is far longer than the thickness of pile tube wall, the power difference that the two is born, therefore the special-shaped pile tube after being shaped is when the demoulding, because the pile tube tube wall is different with planted agent's intensity of force that ring is born, its result causes between combining of pile tube tube wall and ring and produces the crack, causes whole root canal pile to scrap.

Summary of the invention:

Purpose of design: avoid the weak point in the background technology, the one, what be designed to annular concave bar groove and pile tube die cavity wall in the one or both ends of pile tube die cavity vertically is designed to the concavo-convex muscle groove of waveform, purpose is by making pile tube wall after the shaping be wave structure and increase the carrying Area of bearing of pile tube end face and pile body by this wavy shaped configuration, reaching the purpose that improves the pile tube pressure-bearing; The 2nd, waveform pile tube die cavity can make the pile tube internal stress after the shaping obtain discharging at waveform pile tube die cavity, avoids the damage to the shaping pile tube, guarantees the forming quality of the vertical muscle pile tube of waveform, and conveniently stripped.

Design: in order to realize above-mentioned purpose of design.1, waveform bar shape tubular pile mould one or both ends are provided with recessed ring-type concave bar groove, are one of features of the application.The purpose that the tubular mold one or both ends are provided with recessed ring-type concave bar groove is: because the size of pile tube bearing capacity depends on two parameters, one is the size of pile tube end face, one is the size of tubular pile body area, the bearing capacity of pile tube end face account for whole pile tube bearing capacity about 35%, the bearing capacity of tubular pile body area accounts for about 65% of whole pile tube.Therefore the application reaches the area that increases shaping pile tube end face by increasing pile tube mould one or both ends cavity, has just equaled to increase the end face bearing capacity of shaping back pile tube, and this is an one, also is that background technology institute is unsolved.2, the pile tube die wall vertically (along long) be designed to convex-concave ripple (wave) shape muscle groove, and in the groove of the concavo-convex muscle groove of waveform, vertically be provided with the vertical recessed muscle groove of or 2 or many projectioies, be the application feature two.The purpose of design of the concavo-convex muscle groove of waveform is: because the friction that tubular pile body and underground produced is the support force of pile tube, in whole pile tube bearing capacity, tubular pile body accounts for about 65% of whole pile tube bearing capacity, and the application is by being provided with the concavo-convex muscle groove of waveform on the pile tube die cavity, not only can increase the tubular pile body area after the shaping significantly, and can improve the pile tube carrying significantly, ring-type that the more important thing is concavo-convex muscle of wave on the tubular pile body and pipe pile end portion projection stops the ring muscle, not only can give birth to huge friction support power with local products, and improve the block support force of soil property significantly pile tube; Secondly, because when prestressed concrete pipe pile is shaped, the rod iron that is positioned at concrete tubular pile must be haled extension, and the prestressed concrete pipe pile that is positioned at the concrete tubular pile die cavity is after making forming pile, there is huge internal stress in the pile tube inside that is positioned at shaping steel die, this internal stress acts directly on the pile tube, because concavo-convex muscle of waveform and the formed arcuate structure of tubular pile body can satisfy the required intensity of pile tube internal stress disappearance, guarantee that the pile tube internal stress is in the process that disappears, can not produce counter productive, fundamentally solve the pile tube problem of cracks that the pile tube internal stress is caused pile tube itself.3, the vertically design of angle between bottom, concave bar groove inclined-plane and shaping pile tube face between the concavo-convex muscle groove of waveform in the pile tube die cavity, be the application feature three.Purpose of design is: when being shaped owing to prestressed concrete pipe pile, the rod iron that is positioned at concrete tubular pile must be haled extension, and the prestressed concrete pipe pile that is positioned at the concrete tubular pile die cavity is after making forming pile, there is huge internal stress in the pile tube inside that is positioned at shaping steel die, this internal stress acts directly on the pile tube, because vertically convex tendon is distributed on the pile body of pile tube along long, not only can satisfy the required intensity of pile tube internal stress disappearance, guarantee in the process of pile tube internal stress disappearance, and can not produce counter productive to pile tube itself, fundamentally solved the pile tube problem of cracks that the pile tube internal stress causes.Its technical scheme: waveform is indulged muscle pile tube mould, it comprises core rod (2), patrix (4) and counterdie (5), patrix (4) and counterdie (5) are enclosed within on the core rod (2), vertically have the concavo-convex muscle groove of waveform (1) in patrix (4) and counterdie (5) die cavity, vertically be provided with one or 2 or many concave bar grooves (6) between the convex tendon groove in the concavo-convex muscle groove of waveform (1) and communicate with concave bar groove in the concavo-convex muscle groove of waveform (1).

The utility model is compared with background technology, the design of longitudinal rib groove between pile tube mould intracavity wall waveform muscle groove and wave muscle groove, not only make pile tube Area of bearing after the moulding obtain having enlarged effectively, having improved the bearing capacity of pile tube, and solved the defective in the pile tube wall crack that pile tube wall and convex tendon joint portion cause owing to unbalance stress, guarantee the pile tube quality after the moulding, and can be conveniently stripped.
