Abstract
The utility model discloses a kind of band prestress steel pile tube, comprise the end plate at pile body and pile body two ends, described pile body comprises the reinforcing cage of concrete hollow pile body, steel pipe and band prestressed reinforcement, its innovative point is: described steel pipe is coaxially arranged by stretch-draw side steel pipe A and fixation side steel pipe B and forms, the outer end welded end plate respectively of stretch-draw side steel pipe A and fixation side steel pipe B; Described stretch-draw side steel pipe A has a telescopic section that can be slidably matched with fixation side steel pipe B outer wall or inwall.The utility model band prestress steel pile tube can effectively prevent pile for prestressed pipe steel tube end part concrete after prestressed stretch-draw from exposing, and crack thus affect intensity and other performances of product, simply, cost is low for the utility model structure.
Description
Technical field
The utility model relates to a kind of band prestress steel pile tube, particularly relates to a kind of band prestress steel pile tube that effectively can control prestress steel pile tube steel pipe and concrete junction rather.
Background technology
In existing steel pipe pile industry, the structure of prestress steel pile tube comprises the end plate at pile body and pile body two ends, the reinforcing cage that pile body comprises concrete hollow pile body, steel pipe and band prestressed reinforcement by pile body forms, the manufacture craft of tradition prestress steel pile tube is generally: steel pipe machine-shaping, reinforcing cage machine-shaping; Reinforcing cage drops into steel pipe; Left and right end plate is installed; First a side end panel is connected with steel-pipe welding; Tensioning head and stretch-draw tailgate are installed; The steel pipe assembled is placed in punching block; Stretch-draw puts in place as requested; Pumping feeding; Centrifugal, steam-cured; The shortcoming of the steel pipe pile that this manufacture craft is produced is: after stretch-draw, steel tube end part occurs easily cracking the phenomenon that concrete slurry exposes, affect product quality with the concrete of steel tube end part junction.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of prestress steel pile tube, effectively can control the generation of prestress steel pile tube crackle.
For solving above technical problem, the technical solution of the utility model is: a kind of prestress steel pile tube, comprise the end plate at pile body and pile body two ends, described pile body comprises the reinforcing cage of concrete hollow pile body, steel pipe and band prestressed reinforcement, and its innovative point is: described steel pipe has the telescopic section that can adjust entire length in stretching process.
Further, described steel pipe is coaxially arranged by stretch-draw side steel pipe A and fixation side steel pipe B and forms, the outer end welded end plate respectively of stretch-draw side steel pipe A and fixation side steel pipe B;
Described stretch-draw side steel pipe A has a telescopic section that can be slidably matched with fixation side steel pipe B outer wall or inwall.
Further, described stretch-draw side steel pipe A is fixedly made up of end plate connection steel pipe and telescopic section fastener for connection; And the inside and outside footpath of end plate connection steel pipe is consistent with the inside and outside footpath of fixation side steel pipe B.
Further, the reinforcing cage of described prestress steel pile tube is after stretch-draw completes, and telescopic section and the fixation side steel pipe B of stretch-draw side steel pipe A are connected and fixed.
Further, the telescopic section of described stretch-draw side steel pipe A and fixation side steel pipe B are by bolt or be welded and fixed.
The beneficial effects of the utility model are: the steel pipe of the utility model band prestress steel pile tube changes traditional Integral Steel tubular structure, steel pipe has the telescopic section that automatically can adjust entire length in stretching process, be made up of stretch-draw side steel pipe A and fixation side steel pipe B two parts, stretch-draw side steel pipe A is set in fixation side steel pipe B, can move axially along fixation side steel pipe B in fixation side steel pipe B, when prestressed stretch-draw, stretch-draw side steel pipe A pulls out accordingly along with the elongation of reinforcing cage from fixation side steel pipe B, can effectively prevent pile for prestressed pipe steel tube end part concrete after prestressed stretch-draw from exposing, crack thus affect intensity and other performances of product, the utility model structure is simple, cost is low.

Detailed description of the invention
The utility model band prestress steel pile tube comprises the end plate 20 at pile body 10, pile body two ends.
Refer to Fig. 1-4, in order to the generation enabling the utility model band prestress steel pile tube effectively control prestress steel pile tube crackle, the utility model pile body 10 comprises the reinforcing cage 13 of concrete hollow pile body 11, steel pipe 12 and band prestressed reinforcement; Steel pipe 12 has the telescopic section that can adjust entire length in stretching process.
In the present embodiment, steel pipe 12 is coaxially arranged by stretch-draw side steel pipe A 121 and fixation side steel pipe B 122 and forms, the outer end welded end plate 20 respectively of stretch-draw side steel pipe A 121 and fixation side steel pipe B 122;
Stretch-draw side steel pipe A 121 has a telescopic section that can be slidably matched with fixation side steel pipe 122 outer wall or inwall.
Stretch-draw side steel pipe A 121 is connected and fixed by end plate connection steel pipe 121a and telescopic section steel pipe 121b and forms; And the inside and outside footpath of end plate connection steel pipe 121a is consistent with the inside and outside footpath of fixation side steel pipe B122.
The reinforcing cage 13 of prestress steel pile tube is after stretch-draw completes, and telescopic section and the fixation side steel pipe B122 of stretch-draw side steel pipe A121 are connected and fixed.
The telescopic section of stretch-draw side steel pipe A121 and fixation side steel pipe B122 are by bolt or be welded and fixed.
Those skilled in the art should understand; the above embodiments are only exemplary; not circumscribed; such as telescopic section can also be arranged on fixation side steel pipe B; be slidably matched with the outer wall of stretch-draw side steel pipe A or inwall; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
