Abstract
The utility model relates to a bamboo ring shaped pre-stressed pipe pile steel mould, which comprises two blocks of strip half-round body steel moulds that are buckled tightly by fasteners; the utility model is characterized in that each body steel mould is provided with a ring recess every 1-4 m interval, while the ring recess has a cross-section shape as a right-angled trapezoid, or a right-angled trapezoid, or an isosceles trapezoid, the length of the cross-section four edges of the recess is 5-40 cm, and the joints between the ring recess and the and body steel mould and parts of or all of the two arrises of the ring recess are as an R angle. Compared with prior art, the utility model has the advantages that it can produces the bamboo ring shaped pre-stressed pipe pile, the utility model can greatly improve the bearing capacity of single pile compared with present pre-stressed pipe piles with equal wall thickness in soft soil region, the utility model can make good use of the high material bearing capacity of the high-strength pipe pile body, the utility model decreases total pile numbers of the building, and the utility model reduces the construction cost.
Description
Technical field
Utility model ring shape pile for prestressed pipe punching block relates to mechanical manufacturing field, relates in particular to machine die and makes the field.
Background technology
As everyone knows, the existing pile for prestressed pipe that uses in building foundation engineering of China has steady quality, speed of application is fast, the construction site is clean and be widely used.But, the uniform internal diameter of producing with existing pile tube punching block, etc. external diameter and etc. the wall thickness pile tube, in the soft soil foundation in the city of China's coastal economy prosperity, use, it is little to the side friction of stake to exist weak soil, bearing capacity of single pile is not high, make the high-bearing capacity of the high-intensity pile shaft material of pile tube itself can't bring into play and waste, improved the cost of foundation engineering.
Summary of the invention
The purpose of this utility model provides a kind of ring shape pile for prestressed pipe punching block, can produce ring shape pile for prestressed pipe, can increase substantially bearing capacity of single pile, make the high-bearing capacity of high-intensity pile shaft material obtain performance, thereby reduce the building total amount of pile, reach the reduction construction costs, shorten the purpose of construction period.
The purpose of this utility model is to realize by following technical scheme: it is semi-circular with stubborn (button) the tight main body punching block of securing member that ring shape pile for prestressed pipe punching block includes two block length strips, it is characterized in that, 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, the long 5-40cm of groove cross section four edges, part or all establish the R angle in annular recess and main body punching block junction surface and annular recess two corner angle.Annular recess adopts cast steel casting or steel plate to roll and forms, and annular recess punching block and main body punching block are affixed with electric welding or stud.
The utility model compared with prior art, has following advantage: can produce ring shape pile for prestressed pipe with it, than the existing wall thickness pile for prestressed pipe that waits in soft clay area, can improve bearing capacity of single pile significantly, the high-bearing capacity of the high-intensity pile shaft material of pile tube itself can be made full use of, reduce the building total amount of pile, reduce construction costs.
Description of drawings:
Fig. 1 is longitudinal section schematic diagram (a) and the cross sectional representation (b) of utility model embodiment.
The specific embodiment
An exemplary embodiments of the present utility model such as Fig. 1: at first, adopt veneer reeling machine to roll out 1.5～2.5m length, semicircular punching block main body patrix (1) and counterdie (8) quality steel plate; Roll out the annular recess mould (2) of diameter greater than the upper and lower mode diameter 20cm of main body with quality steel plate, annular recess mould (2) is established the R angle with main body mould (1,9) junction, and interior two corner angle of chase form (2) are also established the R angle.Again annular recess (2) is connected with electric welding with the upper and lower mould of main body (1,9) respectively, and 20～40cm is provided with upper and lower mould fastening bolt (4) at interval, promptly finishes ring shape pile tube punching block and make.This punching block is placed on the support, in counterdie (9), put into deformed bar cage (10), and pour a certain amount of concrete into, cover patrix (1), securing member (4) is screwed, again the lid pulpboard (6) at pile tube two ends is set up, deformed bar bolt (5) is tightened.With crane will in the deformed bar cage is housed and concrete the utility model hangs on two groups of rollers (11), hotwire (7), drive roller (11) with whole punching block fast rotational through power transmission shaft (8), the punching block inner concrete is centrifuged into pile tube (12), the punching block of slinging places steam-cured pond, after treating that concrete strength reaches, turn on fastening bolt (4, the 5) demoulding, promptly made a joint ring shape pile for prestressed pipe (12) with this ring shape pile for prestressed pipe punching block, go round and begin again, make required ring shape pile for prestressed pipe.
Claims (1)
1. utility model ring shape pile for prestressed pipe punching block includes that two block length strips are semi-circular twists (button) tight main body punching block with securing member, it is characterized in that, 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, the long 5-40cm of groove cross section four edges, part or all establish the R angle in annular recess and main body punching block junction surface and annular recess two corner angle.
