Abstract
The utility model discloses a prestress square pile end plate which comprises an end plate body (1) with a square section. A plurality of bolt anchoring holes (2), a plurality of prestress steel bar locating holes (3) and upset head passing holes (4) with the matched number are formed in the end plate body (1), and the prestress steel bar locating holes (3) are further communicated with the upset head passing holes (4). The prestress square pile end plate is characterized in that the inner circles of the prestress steel bar locating holes (3) are tangent to protective layer lines (5) and are formed in the inner sides of the protective layer lines (5), all the prestress steel bar locating holes (3) are formed in the same sides of the upset head passing holes (4), the circle center connecting lines of the prestress steel bar locating holes (3) and the upset head passing holes (4) of different sets are parallel or are overlapped, and the upset head passing holes (4) coincide with the circle centers of the corresponding bolt anchoring holes (2). The prestress square pile end plate can guarantee that all kinds of mechanical properties of prestress square pile design cannot be changed, and is convenient to mount.
Description
Technical field
The utility model relates to a kind of concrete pile supplementary structure, particularly a kind of prestress square pile end plate.
Background technology
Since prestressing force reinforced concrete rectangle pile is born, the establishment processing mechanization of prestress square pile cages, industrialization degree are more and more higher, but the mechanization degree of square pile reinforcing cage is large compared with pile tube difficulty.Its reason is: the main muscle of pile tube is that axle is equidistantly equally distributed centered by pile tube kernel of section, and the each main muscle of square pile reinforcing cage is not apart from the distance of square pile kernel of section point etc., four angle point maximums, four limit intermediate point minimums, increased difficulty to mechanization, reinforcing cage has also increased difficulty to the installation of end plate after having worked out simultaneously.
Traditional square pile end plate bolt anchoring hole and main muscle locating hole are to be all distributed on each limit according to clockwise whole or whole counterclockwise modes, be that bolt anchoring hole and main muscle position of positioning hole on corresponding parallel both sides is contrary, this distribution mode is unfavorable for end plate to be arranged on the reinforcing cage having woven, even on solar obligation, the limit of end plate and reinforcing cage limit also cannot guarantee to be parallel to each other, even end plate neither be parallel with the each limit of pile body, whole welded end plate while causing pile extension.In addition for the ease of installing, also have conglobate the reinforcing cage processing of square pile, namely also image tube pile end plate is the same distributes for the line of centres of the bolt anchoring hole on end plate and main muscle locating hole, but this mode has changed the position of the main muscle of square pile, the shape of stirrup, also just change the mechanical property of square pile.
Therefore need now a kind of novel pre-stressed square pile end plate structure that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of can not being changed in the every mechanical property that guarantees prestress square pile design, and prestress square pile end plate easy for installation.
Technical solution of the present utility model is: a kind of prestress square pile end plate, comprise that cross section is square header body 1, in header body 1, offer multiple bolt anchorings hole 2, the heading that multiple prestressed steel bar locating holes 3 and quantity match is by hole 4, prestressed steel bar locating hole 3 is also communicated with by hole 4 with heading, it is characterized in that: the inner circle of prestressed steel bar locating hole 3 with protection layer line 5 tangent and be positioned at protection layer line 5 inner side, all described prestressed steel bar locating holes 3 are all positioned at heading by the same side in hole 4, and between prestressed steel bar locating hole 3 on the same group and the circle center line connecting of heading by hole 4, be not parallel to each other or overlapping.
Described heading is the center of circle coincidence with corresponding bolt anchoring hole 2 by hole 4.
Compared with the existing technology, tool has the following advantages the utility model:
The prestress square pile tip plate configurations the utility model proposes, for traditional square pile end plate when mounted, owing to having unreasonable factor in its bolt anchoring hole and the design of prestressed steel bar locating hole, cause the installation limit of end plate and the limit of reinforcing cage cannot guarantee parallel, while causing pile extension, cannot carry out all-welded problem to end plate, all prestressed steel bar locating holes are all arranged on to heading by the same side in hole, and guarantee between rod iron locating hole on the same group and the circle center line connecting of heading by hole, not to be parallel to each other (or overlapping), penetrate heading by behind hole at all (rod iron) headings like this, only need to apply a radial load towards rod iron locating hole just can disposablely allow all rod irons enter prestressed steel bar locating hole, and after completing, guarantee that all bolts are parallel mutually with all prestressed steel bars.The appearance of this prestress square pile end plate, can not change under the condition of the design parameters of square pile, mechanical property, allow the each several part structure configuration of square pile can give full play to its maximum performance advantage, make the installation of the each parts of reinforcing cage easier, quick, save a large amount of manpower and operating time, improve output, speed production beat; And apply the outward appearance rule, attractive in appearance of the concrete square pile of this kind of end plate, in the time of pile extension, end plate alignment, can guarantee welding quality and workmanship.And its manufacture craft is simple, cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment mono-.
Fig. 2 is the structural representation of the utility model embodiment bis-.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.As Fig. 1, shown in Fig. 2: a kind of prestress square pile end plate, comprise as basic header body 1, the sheet material that header body 1 is square for cross section, the general steel that adopts is made, in header body 1, offer multiple bolt anchorings hole 2, multiple prestressed steel bar locating holes 3 and the heading that matches with its quantity are by hole 4, each heading is by the corresponding prestressed steel bar locating hole 3 in hole 4, and prestressed steel bar locating hole 3 is interconnected by hole 4 with heading, all prestressed steel bar locating holes 3 are all positioned at heading by the same side in hole 4, and different prestressed steel bar locating holes 3 and heading are parallel to each other by the circle center line connecting between hole 4, or overlapped (conllinear),
Another embodiment of the present utility model can allow heading pass through hole 4 and overlap with the center of circle in corresponding bolt anchoring hole 2.
The course of work of the prestress square pile end plate of the utility model embodiment is as follows: in embodiment mono-, first the pier nose of all prestressed steel bars is together inserted to pier nose by hole 4, allow the larger pier nose of diameter pass completely through pier nose by hole 4, then the into a single integrated structure reinforcing cage of colligation is applied to a power radially, allow prestressed steel bar transverse movement, prestressed steel bar enters in prestressed steel bar locating hole 3 and carries out anchoring, simultaneously in bolt anchoring hole 2, interior cross-under has anchoring bolt, realizes being connected and applying prestressing force of end plate and prestressing force machine drawing.
