Abstract
The invention relates to a prestressed concrete tubular pile end plate. The specific scheme is that: a circular steel plate (1) is provided; a plurality of tensioning steel bar positioning holes (3) and tensioning steel bar perforations (5) connected with the tensioning steel bar positioning holes (3) are formed on the middle part of the circular steel plate (1); the number of tensioning bolt fixing anchor holes (4) is as same as that of the tensioning steel bar positioning holes; annular grooves (2) are formed on the inner sides of the holes; pile extension welding semi-U shaped beveled edges (6) are formed on the right of the outer sides of the holes; and pile hoop assembling steps (7) are formed on the left of the outer sides of the holes. The prestressed concrete tubular pile end plate is characterized in that: due to single arrangement of the tensioning bolt fixing anchor holes, the contact area of tensioning bolts and the tensioning plate fixing anchor holes is increased, stress concentration of the tensioning bolts is effectively reduced, the tensioning blots are prevented from dropping off, and the thickness of the end plate can be reduced when the bearing force is the same; and due to the arrangement of the welding beveled edges and the assembling steps on the outer sides of the holes, welding quality is guaranteed, assembling efficiency is improved, and steel material consumption of the end plate is reduced.
Description
Technical field:
The invention belongs to prestressed concrete pipe pile end plate in building material industry.
Background technology:
Prestressed concrete pipe pile end plate is mounted in the parts at prestressed concrete pipe pile two ends, be mainly used in prestressed stretch-draw anchor and the pile extension in constructing in pile tube production, its agent structure is an annular steel plate, the isometrical of anchor ring centre circumferentially has some stretch-draw bolts hole, stretch-draw bolt hole side has the tension reinforcing steel bar stationary positioned hole be communicated with stretch-draw bolt hole, in making prestressed concrete pipe pile process, main for steel reinforcement cage concrete steel rod is passed pile end board and is fixed in tension reinforcing steel bar locating hole, stretch-draw rod iron is carried out by the turnbuckle through stretch-draw bolt hole, to rod iron Shi Hanzhang, end plate all will bear larger active force when rod iron Shi Hanzhang and piling, so in order to ensure certain intensity, existing prestressed concrete pipe pile end plate thickness is generally between 16-20mm, and whole end plate thickness is even, consumes steel more, rod iron perforation is all a hole with stretch-draw bolt hole, and stretch-draw bolt hole and stretch-draw threaded bolt contacts face reduce about 1/4, and turnbuckle stress concentration phenomenon is remarkable, easily causes bolt to pull, cause whole piece semi-finished product pile tube to scrap in steel bar tensing technique.
The production and construction techniques relevant to end plate also comprises: the assembling of end plate and pile protection hoop and welding, and during pile extension, two root canal pile end plates and end plate welds.Efficiency of assembling, welding quality are one of key factors ensureing pile tube production efficiency, engineering safety.Existing planar end surface pile end board is unfavorable for the assembling and the welding quality that improve end plate and pile protection hoop, to the raising of pile extension welding quality without help.
Authorization Notice No. CN2616351Y utility model patent relates to a kind of pile for prestressed pipe end plate, the technical problem solved is the rolled steel dosage of saving end plate, adopt large concave design, all loop concave is had in inner side and outer side, stretching screw hole, for making up the reduction of the end plate mechanical property that concave surface brings, reinforcement is adopted to ensure end plate intensity.
Summary of the invention:
The technical problem to be solved in the present invention is under the prerequisite meeting prestressed concrete pipe pile end plate basic mechanical performance, in line with the principle reducing end plate steel consumption amount, from the design of change tip plate configurations, avoid pulling of stretch-draw bolt in tubular piles stretching technique, improve the qualification rate of tubular piles stretching technique, contribute to the efficiency of assembling improving end plate and pile protection hoop, contribute to the welding quality of guarantee end plate and pile protection hoop, the welding quality of pile extension in tube pile construction.
The concrete scheme solved the problem is: the steel plate (1) being provided with annular, have several stretch-draw rod iron locating holes (3) in the middle and bore a hole (5) with the stretch-draw rod iron be connected, the stretch-draw screw anchor hole (4) that quantity is identical with stretch-draw rod iron locating hole, ring-shaped groove (2) is had inside hole, outside hole, the right is provided with pile extension welding half U type groove (6), and the left side is provided with pile protection hoop assembling step (7).
In actual applications, prestressed stretch-draw bolt hole is arranged separately, make stretch-draw bolt hole and stretch-draw threaded bolt contacts face increase about 1/4, the stress effectively reducing stretch-draw bolt is concentrated, and avoids in steel bar tensing because bolt pulls the situation causing whole piece semi-finished product pile tube to scrap; When bearing capacity is identical, can end plate thickness be reduced, thus decrease the steel consumption of end plate.Stretch-draw bolt ring week is stressed maximum, arranges ring-shaped groove (2) within it, at its arranged outside pile extension bevel for welding (6) and pile protection hoop assembling step (7), does not affect the bearing capacity in end plate use; This design is not only conducive to the efficiency of assembling improving pile protection hoop, ensures the welding quality of pile protection hoop and end plate, ensures the welding of pile extension in construction, also reduces the steel consumption of end plate simultaneously.

Specific embodiments:
Below in conjunction with embodiment and Figure of description, the present invention is further described:
Tension reinforcing steel bar perforation (5) that steel plate (1) the isometrical circumferential position of annular has 10 tension reinforcing steel bar stationary positioned holes (3) and is connected with it, be not connected with tension reinforcing steel bar locating hole (3) and have 10 stretch-draw screw anchor holes (4), have ring-shaped groove (2) inside hole, outside hole, be provided with pile tube opposed end panel welding half U type groove (6) and pile protection hoop assembling step (7).
