Abstract
The utility model relates to a ring-rib tubular pile, belonging to a concrete tubular pile for building foundation engineering, which comprises a pile body with ring-shaped protruding ribs which are arranged in a certain distance on the outer wall of the pile body in a way that the front slope of the protruding rib is at 175-90 degrees angle of Alpha to the outer surface of the pile body and the rear slope is at 90-175 degrees angle of Beta. The utility model has the advantages that the plurality of ring-shaped protruding ribs on the outer wall of the pile body can increase both effective support area and bearing capacity of the whole tubular pile; the cross-sectional bottom slant edge of the ring-shaped protruding ribs form an included angle to the tubular pile surface, defining a buffer zone at the juncture between the tubular pile wall and the ring-shaped protruding rib; the buffer zone can meet the requirement of strength for offsetting the inner stress of the tubular pile, to avoid the damage of inner stress to the tubular pile, ensure the quality of molded tubular pile, and facilitate the demoulding.
Description
Technical field:
The utility model relates to a kind of building foundation engineering concrete special pile tube, belongs to concrete tubular pile and makes the field.
Background technology:
Notice of authorization CN2611433Y, title " pretensioning prestressed concrete abnormity pile tube ", this abnormity pile tube comprises the stake body that extends vertically, be provided with reinforcing rib in the stake body, be provided with the ring projection that radially becomes big at intervals on the stake body, the stake body between the ring projection is cylindrical.Its weak point: because the end of this abnormity pile tube is less than the diameter between its ring projection, therefore not only its loaded area is little, and bearing capacity is big; The 2nd, because the wall of special-shaped pile tube lacks vertical convex tendon, therefore resistance to compression, the flexural strength of whole pile tube are low, anti-shearing force is poor, make easily to cause pile tube to rupture by the waist in the follow-up construction of pile tube after piling and piling or phenomenon such as fracture; The 3rd, though the part of ring projection has increased the entire area of pile tube, but the increase deficiency of this area remedies the cost of production that ring lug boss branch produces, two difficulties that the carrying specification of pile tube are in whether go up, descend are wherein up leaned on (substituting large-diameter tubular pile), and then bearing capacity is not enough; Up do not lean on, though bearing capacity has surpassed the standard of its setting, waste one's talent on a petty job, make building costs increase considerably, the owner is reluctant to adopt.
Summary of the invention:
Purpose of design: avoid the weak point in the background technology, the one, in the one or both ends of pile tube and the pile body of pile tube protruding ring-type convex tendon is set at interval, by the pressure-bearing Area of bearing of increase pile tube end face and the area of tubular pile body, reach the purpose that improves the pile tube bearing pressure; The 2nd, by qualification to ring-type on the pile tube tube wall and bottom, vertical raised ribs cross section and pile tube wall angle; make the ring-type convex tendon of the tube wall of pile tube and projection and vertically form internal stress buffering fade zone between convex tendon; make the pile tube internal stress after the shaping can be in the release that obtains between formed buffering fade zone between raised ribs and pile tube wall progressively; avoid the crack that produced between pile tube wall and convex tendon joint portion and conveniently stripped, guarantee to encircle the forming quality of bar shape tubular pile.
Design scheme: in order to realize the application's above-mentioned purpose.The application is on the basis of existing special-shaped pile tube: 1, the pile body one or both ends are provided with the ring-type convex tendon of projection, are one of features of the application.The purpose that the pile body one or both ends are provided with the ring-type convex tendon of projection is: because the size of the bearing capacity of pile tube 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 increases the area of pile tube end face, just equals to have increased the bearing capacity of pile tube, and this is an one, also is that background technology institute is unsolved.2, be located at interval at the design of the ring-type convex tendon of a plurality of projectioies on the pile tube wall, be the application feature two.The purpose of ring-type convex tendon design is at interval: 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 provided with the ring-type convex tendon at interval on the pile tube wall, not only can increase the effective area of tubular pile body significantly, and can improve the pile tube bearing capacity significantly, the more important thing is the interval ring-type convex tendon on the tubular pile body and the formed prevention ring of ring-type convex tendon of pipe pile end portion, can form prevention with soil and cooperate, improve the block support force of soil property significantly stake.3, the pile tube wall be positioned at the go to the bottom design of angle of ring-type convex tendon cross section on the pile tube wall, be the application feature three.The go to the bottom purpose of design of angle of pile tube wall and shape ring convex tendon cross section is: because prestressed concrete pipe pile is when being 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 concrete tubular pile shaping steel die cover 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, owing to be provided with certain included angle between ring-type convex tendon and tubular pile body face, the inclined-plane that this angle is produced the both sides (cross section is two trapezoidal waists) of ring-type convex tendon can satisfy the required intensity of pile tube internal stress disappearance, guarantee in the process of pile tube internal stress disappearance, can not produce counter productive, fundamentally solve the pile tube problem of cracks that the pile tube internal stress is caused pile tube itself.Its technical scheme: ring muscle pile tube, it comprises pile body (7), the outer wall of pile body (7) is interval with the ring-type convex tendon (5) of projection, and the ring-type convex tendon (5) preceding domatic (4) of projection is that 179～90 degree, back domatic (6) are 90～179 degree with pile body face (3) angle β with pile body face (3) angle α.
The utility model is compared with background technology, the one, the design of the ring-type convex tendon of multi-turn projection on the pile tube outer wall, not only enlarge effective Area of bearing of whole pile tube effectively, and improved the supporting capacity of pile tube significantly, its φ 400mm pile tube bearing capacity is equivalent to the bearing capacity of φ 500mm pile tube, greatly reduce cost of production, satisfied the required intensity of pile tube internal stress disappearance simultaneously, avoided of the infringement of pile tube internal stress pile tube; The 2nd, be positioned at the design of bottom hypotenuse of ring-type convex tendon cross section on the pile tube wall and pile tube face angle, not only make the joint portion of pile tube wall and ring-type convex tendon form a buffer area, and this buffer area can satisfy the required intensity of pile tube internal stress disappearance, avoided of the damage of pile tube internal stress to pile tube, pile tube quality after guaranteeing to be shaped, and can be conveniently stripped.
