Abstract
The utility model discloses an end plate for a tubular pile, which comprises a tubular pile, end plates connected at both ends of the tubular pile and ferrules arranged on the end plates. The end plate is characterized in that a circle of grooves is arranged on the periphery wall of the end plate, the ferrules are sleeved in the grooves, and partial ferrules are exposed out of the notches of the grooves. The utility model takes rubber, silica gel or plastic rings as the ferrule material of the end plate, the steel ferrules are replaced, therefore, not only the steel is saved, but also the cost of the ferrules and the pollution to the production site are also reduced. The ferrules are fastened in the grooves of the end plate, and cannot distort due to the foreign force during the production process to cause grout leakage of the pile head to lead to quality problem of pile head bear, and meanwhile, during the centrifugal forming process of the tubular pile, the ferrules are closely matched with the inner surface of the pipe die, and the phenomenon that the concrete paste leaks to affect the appearance quality of the finished product tubular pile is avoided.
Description
Technical field:
The utility model relates to the pile foundation Foundation Design technology in the building field, is specifically related to the end plate of prestressed high-strength concrete pile.
Background technology:
Prestressed high-strength concrete pile is widely used in the engineering constructions such as building, road, bridge, harbour with its superior performance.The two ends of this pile tube all are connected with end plate, in the manufacturing process of pile tube, in order to prevent the spillage in centrifugal, and strengthen the radiating effect in the pile tube spreading welding process, are provided with cuff at the periphery wall of end plate.All the time, cuff all is to adopt sheet metal to make (generally adopting the Q255 steel band), there is following defective: the one, and with sheet metal cost of manufacture height, processing technology complexity, operator's labour intensity is big.The 2nd, in cuff manufacturing process,, can produce waste gas simultaneously because of welding can produce a large amount of ultraviolet radiations, operating environment of pollution not only, and impair the healthy of operator.The 3rd, cuff is subject to external force influence distortion in process of production, causes quality problems such as pile crown bear thereby cause pile crown to run slurry; Simultaneously, owing to be to be welded,, then also might when stretch-draw, cause cuff and end plate to break away from if welding quality is not good.The 4th, the cuff of metal material can't closely contact with pipe die, in the tubular pile centrifugal forming process, often causes concrete mortar to leak, and the slurry that leaks is wrapped in the pile crown side, influences the pile tube presentation quality.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of pile end board, and the cuff of end plate not only cost is low, and can closely contact with pipe die, in the tubular pile centrifugal forming process, the spillage phenomenon can not take place, simultaneously, and the environment pollution of no manufacturing process.
The utility model is achieved through the following technical solutions:
A kind of pile end board comprises pile tube, is connected in the end plate at pile tube two ends, is arranged at the cuff on the end plate, characteristics are that the end plate periphery wall is provided with a circle groove, cuff is placed in the groove, and the part entity exposes the recess of groove, and described cuff is the material with certain degree of hardness.
Described cuff is the 0 shape circle with material of certain degree of hardness, and its internal diameter is less than the groover rot diameter 2-4 millimeter of groove, and its external diameter is greater than end plate external diameter 2-5 millimeter; Cuff is placed in the groove, and the part entity exposes the recess of groove.
Groove is positioned on this end outer wall of end plate inner face, apart from inner face 1-4 millimeter.
The section of groove is a rectangle, or is semicircle, and the section of cuff is a rectangle or for circular, the section rectangle width of cuff, round diameter is greater than recess width 1-3 millimeter, or the rectangle width of cuff section is consistent with recess width.Cuff is tightly restrainted in groove after being placed in the groove.
Cuff is rubber, silica gel or the plastic cement that has in certain degree of hardness and the rubber-like material.
The utility model compared with prior art has following obvious advantage:
One, the utility model overlaps hoop material with rubber, silica gel or plastic tube as end plate, and instead of steel material cuff had both been saved steel, had reduced the cuff cost again.
Two, only need injection molded with rubber, silica gel or plastic cement as the cover hoop material, it makes simple, and the production scene is pollution-free, and operator's labour intensity is low.
Three, what is more important, both soft, flexible again with the cuff of this material, temper toughness with gentleness with end plate, tightly restraint in the groove of end plate, neither can be out of shape in the production because of the external force effect, cause pile crown to run slurry and cause quality problems such as pile crown bear; Simultaneously, in the tubular pile centrifugal forming process, cuff and pipe die inner surface closely cooperate, and concrete mortar can not take place yet leak, and cause finished product pile tube appearance quality.
