Abstract
The invention relates to a fast joint for tubular piles. The innovation point of the invention is that the fast joint for the tubular piles comprises a pair of connecting flange plates and a plurality of circular arc-shaped hoop plates, wherein the connecting flange plates are respectively welded at the positions of end plates of the tubular piles which need to be connected; the outer ends of the connecting flange plates are respectively provided with a ring flange; a plurality of radial threaded holes are distributed on the outer surface of the connecting flange plate at the inner side of each ring flange; the center of the inner arc of each hoop plate is provided with a positioning embedded groove; the ring flanges of the two connecting flange plates of which the outer end faces are in close butt joint just can be embedded in the positioning embedded grooves of the hoop plates; and the hoop plates are respectively and fixedly connected with the two connecting flange plates through bolts. The fast joint for the tubular piles has the advantages that the hoop plates are respectively and fixedly connected with the two connecting flange plates at the positions of the end plates of the tubular piles, and thus, the connection of an upper pile and a lower pile is realized. The fast joint for the tubular piles is reasonable in structure and short in pile connection time, and is suffered from less environmental influence. A welding process is not needed; the connection method can be simply learnt; and the tubular pile connection reliability is also improved. The fast joint for the tubular piles is especially suitable for being applied to the hole-guiding or planting pile-forming process.
Description
Technical field
The present invention relates to a kind of pile tube jointing, particularly a kind of pile tube fast connecting joint.
Background technology
The PHC pile tube, namely the prestressed high strength concrete pile tube is the mixed doubtful native prefabricated units of a kind of hollow cylinder shape that adopt the pre-tensioned prestressing centrifugal molding process to make.Have the advantages such as bearing capacity of single pile height, pile sinking reliable in quality, construction costs be cheap.The prestressed high strength concrete pile tube generally uses in engineering, but pipe pile joint all adopts electric welding to connect at present, and solder technology is consuming time many.Calculate with each joint engineering time, adopt arc welding to need 30 minutes approximately, adopt carbon dioxide gas arc welding to need 15 minutes approximately, and welding is subjected to weather, ambient influnence large, the bad accident resulting from poor quality of projects that causes easily of welding quality.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of efficient and convenient, be connected firmly, safety and connect the pile tube fast connecting joint be not subjected to environment, weather effect.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of pile tube fast connecting joint, its innovative point is: comprise a pair of mounting flange, this is welded on respectively the pile end board place that needs connection to mounting flange, the outer end of mounting flange arranges annular lip, and the mounting flange external surface of annular lip inboard is distributed with some radial screw bore; Several circular arc anchor ear plates, the inner arc center of described anchor ear plate have the location embeded slot that arranges along the circular arc bearing of trend, and the arc convex outer arc surface that embeded slot both sides, location form has the through hole corresponding with two mounting flange radial screw bore; The location embeded slot of anchor ear plate just can hold the mounting flange annular lip of being close to docking in two outer faces and embed, and the anchor ear plate is connected and fixed with two mounting flanges respectively by bolt.
Further, described anchor ear plate quantity is three, and its circular arc number of degrees are 120 °, and anchor ear plate head and the tail outside mounting flange are connected can consist of an annulus.
The invention has the advantages that: utilize the mounting flange at anchor ear plate and pile end board place to be connected and fixed respectively, realize the connection of upper and lower joint stake; Rational in infrastructure, the pile extension time is short, and is affected by environment little, removed welding procedure from, easy to learn, also improved the reliability that pile tube connects, and suits especially drawing the hole or planting pile-formation process and use.

Fig. 2 is anchor ear plated construction schematic diagram among the present invention.
Fig. 3 is fast connecting joint connection diagram of the present invention.
The specific embodiment
As shown in Figure 1, fast connecting joint 3 comprises a pair of mounting flange 31, and this replaces the pile end board place that traditional shirt rim is welded on respectively needs connection to mounting flange 31, and it welded before pile tube is transported to the job site.The outer end of mounting flange 31 arranges annular lip 32, and mounting flange 31 external surfaces of annular lip 32 inboards are distributed with some radial screw bore 33, and radial screw bore 33 quantity of single mounting flange 31 are nine in the present embodiment.
As shown in Figure 2, also comprise three circular arc anchor ear plates 34, its circular arc number of degrees are 120 °, three's tandem array can consist of an annulus, the inner arc center of anchor ear plate 34 has the location embeded slot 35 that arranges along the circular arc bearing of trend, the protruding outer arc of the upper and lower layer surface that embeded slot both sides, anchor ear plate 34 location form has six through holes 36 corresponding with two mounting flange radial screw bore 33, and two-layer protruding outer arc is opened respectively three.
Location embeded slot 35 sizes and the mounting flange 31 of anchor ear plate 34 match, and location embeded slot 35 width are the twice of adpting flange annular lip 32 thickness, make it just can hold the mounting flange annular lip of being close to docking in two outer faces and embed.
During connection, as shown in Figure 3, two pile tubes that need to connect dock, so that two mounting flanges, 31 outer faces at pile end board place are close to; Install anchor ear plate 34 at mounting flange 31 external surfaces, so that the annular lip 32 of two mounting flanges 31 embeds in the embeded slot 35 of location, and the through hole of anchor ear plate 34 is corresponding with screwed hole 33, by bolt 37 anchor ear plate 34 and two mounting flanges 31 are connected and fixed, by three anchor ear plates 34 that form annular pile tube are connected and fixed.Bolt 37 use torque spanner so that need reach design torsion.
