Technical field
The utility model relates to a kind of compound pile, and particularly a kind of post stretching heavy caliber SC shaped steel mixes stake or post and PHC stake compound pile.
Background technology
Pile tube is divided into prestressed concrete pipe pile and prestressed high-strength concrete pile by strength grade of concrete or effective compressive pre-stress.Prestressed concrete pipe pile code name is PC, and prestressed high-strength concrete pile code name is PHC, and thin-wall pipe pile code name is PTC.The concrete strength of PC stake must not lower than C60, and thin-wall pipe pile strength grade must not must not lower than C80 lower than the strength grade of concrete of C60, PHC stake.
The PC stake adopting pre-tensioning system to produce and PHC stake at home the engineering such as building, bridge are used widely, but due to the reason of the aspect such as plant equipment, transportation technology, pre-tensioning system technique is only limitted to produce external diameter 300mm-1000mm, the pile tube of joint length 7m-15m, and in the engineerings such as some large and medium-sized port and pier, bridges, the pile tube that some length of most needs are longer, and current existing pile tube does not reach such requirement.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of major diameter, the post stretching heavy caliber SC shaped steel of overlength degree mixes stake or post and PHC stake compound pile.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of post stretching heavy caliber SC shaped steel mixes stake or post and PHC stake compound pile, and its innovative point is: be welded by steel reinforced concrete stake and PHC stake;
Described steel reinforced concrete stake is saved by stake push pipe, middle tube coupling and stake bottom tube save assembled, and between stake push pipe joint with middle tube coupling and middle tube coupling and stake bottom tube save between seam crossing be welded and fixed by reinforcing sleeve;
Described steel reinforced concrete stake is specially with being connected between PHC stake: save one end adjacent with PHC stake at stake push pipe bonded to each other, be sleeved on a push pipe joint with on the circumferential outer surface of PHC stake by a plate simultaneously, and junction plate and stake push pipe save, be welded and fixed between PHC stake, also there is a reinforcing sleeve respectively at the two ends of junction plate simultaneously.
Further, described stake push pipe joint, assembled between middle tube coupling and stake bottom tube joint is specially: save at stake push pipe, the relevant position of middle tube coupling and stake bottom tube joint all has several push pipe that runs through respectively and saves, the preformed hole of middle tube coupling and stake bottom tube joint, described preformed hole has several, save along stake push pipe, the circumferencial direction of middle tube coupling and stake bottom tube joint is uniformly distributed successively, by steel strand through being positioned at a push pipe joint, the preformed hole that middle tube coupling and stake bottom tube save realizes stake push pipe joint, middle tube coupling and stake bottom tube save the connection between three, and inject concrete in remaining space upon connection in preformed hole.
Further, the length of described stake push pipe joint is 4000mm, and the length of middle tube coupling is 4000mm, and the length of stake bottom tube joint is between 1000mm-4000mm.
The utility model has the advantage of: the compound pile in the utility model not only can meet length and the diameter demand of some overlength pile tubes, and by regulating the length of steel reinforced concrete dress, the length of the compound pile of entirety is adjusted, also can be guaranteed in intensity and anti-bending strength etc. simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that post stretching heavy caliber SC shaped steel of the present utility model mixes stake or post and PHC stake compound pile.
Detailed description of the invention
Schematic diagram is as shown in Figure 1 known, and post stretching heavy caliber SC shaped steel of the present utility model mixes stake or post and PHC stake compound pile and is welded by steel reinforced concrete stake and PHC stake;
Steel reinforced concrete stake saves 3 by stake push pipe, middle tube coupling 2 and stake bottom tube save 1 assembled, and between stake push pipe joint 3 and middle tube coupling 2 and middle tube coupling 2 and stake bottom tube save 1 between be provided with reinforcing sleeve 4.
Stake push pipe joint 3, assembled between middle tube coupling 2 and stake bottom tube joint 1 is specially: at stake push pipe joint 3, the relevant position of middle tube coupling 2 and stake bottom tube joint 1 all has several push pipe that runs through respectively and saves 3, the preformed hole of middle tube coupling 2 and stake bottom tube joint 1, preformed hole has several, along stake push pipe joint 3, the circumferencial direction of middle tube coupling 2 and stake bottom tube joint 1 is uniformly distributed successively, by steel strand through being positioned at a push pipe joint 3, middle tube coupling 2 and the stake bottom tube preformed hole saved on 1 realize stake push pipe joint 3, middle tube coupling 2 and stake bottom tube save the connection between 1 three, and inject concrete in remaining space upon connection in preformed hole, thus defined and be bonded with prestressed pile.
Carry out assembled before cleaning reserving hole channel, ensure duct clean unimpeded, assembled front worn tube coupling section laitance, concordant, greasy dirt, smooth be coated in tube coupling head by full uniformly for cementing agent; Look into adjustment to splicing station car test before splicing, time assembled, obvious mark is made in corresponding preformed hole position.
