Abstract
The utility model belongs to the architecture field, and relates to the pile splice technology that in the architecture field, the linking is conducted between section piles to the length of a foundation pile according to the construction requirement. A concrete square pile splice comprises quadrilateral end plates which are arranged on a slicing face of two square piles, and is characterized in that the quadrilateral end plate which is arranged on the slicing face of two square piles is welded with a connection board which is of square-set shape, the periphery of the connection board is coincided with the quadrilateral end plate, the end plate and the connection board are welded with a welding portion, the welding portion is welded with the other ends of two connection boards, a tension supplementary plate which is provided with a right-angled trapezoid or right-angled triangle cross-section is tightly welded with the connection board and the end plate at intervals of a certain distance, a circle of welding stress soldering arc grooves are arranged at the position which is arranged on the two quadrilateral end plates and is in a distance of 3-5 mm from the all-around position of the end plates. Because the connection board which is welded with the end plate on the slicing face of two square piles is existed, the pile body cannot be damaged in the welding, which is convenient for detecting each quality index of welded slits after the welding is provided. The tension supplementary plate is tightly welded between the end plate and the connection board, and the end plate and the connection board are tightly and firmly connected.
Description
Technical field
The utility model belongs to building field, relates to need particularly implement the pile joint of connection to the joint stake of hollow concrete side's stake to the pile joint technology that is connected between the stake of concrete base pile length enforcement joint by construction in the building field.
Background technology
Piling as the foundation pile engineering has pile tube, all kinds of side stake, castinplace pile, drilled pile etc.In work progress, all to prove the length of foundation pile according to the ground situation.Thereafter, in a planned way to some concrete joint stake enforcements welding successively.Therefore, the joint construction of welding how between joint stake, and how its quality can directly influence every index performances such as the bearing capacity, bending resistance, shearing resistance of foundation pile.So the high-quality of concrete pile joint is the important ring of whole quality of pile and being paid attention to by people.At present, welding (Fig. 3) form between the end plate of joint stake two ends is generally adopted in the connection of concrete square pile joint stake.This syndeton causes a little less than whole stake bending resistance, the shear resistance.Simultaneously, because end plate is very near from concrete, electric welding heat can cause serious harm to the concrete pile body during welding.In addition, the detecting operation that welded construction is returned the detection tabs quality between end plate brings difficulty.Design a kind of rational in infrastructurely, easily welding can not injure pile body in the welding, is convenient to pile joint structure that the every quality index of soldered detects after the welding and has put a important topic the pile foundation those skilled in the art.
Summary of the invention
The purpose of the utility model is to remedy above-mentioned described deficiency, discloses a kind of rational in infrastructurely to society, and quality is good, and easily welding can not injure pile body in the welding, is convenient to the pile joint that the every quality index of soldered detects after the welding.
Design scheme of the present utility model is achieved in that
A kind of concrete square pile joint comprises, two sides stake connects the quadrangle end plate of face, it is characterized in that, two sides stake connect face be provided with the welding of quadrangle end plate be square frame shape, periphery and the identical junction plate of quadrangle end plate, the weld part that end plate and junction plate weld; Weld part with the welding of two junction plate other ends; The cross section is right-angled trapezium or right-angled triangle, replenishes plate every the tension of a segment distance and end plate and the tight welding of junction plate.
The weld part of described quadrangle end plate and junction plate welding is the bevel for welding place around the quadrangle end plate.
Described junction plate thickness is 20-60MM.
Bevel for welding 3-5MM place on the described two quadrangle end plates around end plate is provided with a circle welding stress welding arc fluting.The degree of depth of welding stress welding arc fluting is 3-6MM, width 5-7MM.
Described tension is replenished plate and end plate and the tight weld part of junction plate and is established bevel for welding, and groove is the 40-60 degree.
Described weld part with the welding of two junction plate other ends, gapped between two junction plates.
The utility model has the advantages that:
1) because, connect the existence that is the identical junction plate of square frame shape, periphery and quadrangle end plate of the quadrangle end plate welding of face with two sides stake, so, can not injure pile body in the welding, be convenient to detection after the welding to the every quality index of soldered.
2) cross section be right-angled trapezium or right-angled triangle, every the closely tension of the welding existence that replenishes plate of a segment distance and end plate and junction plate, so, be connected very close and firm between end plate and junction plate.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram (sectional view);
Fig. 2 is Fig. 1 embodiment A portion enlarged diagram;
Fig. 3 is a concrete square pile ordinary couplings schematic diagram;
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
A kind of concrete square pile joint, comprise that two sides stake 1,1 ' connects the quadrangle end plate 2 of face, it is characterized in that, two sides stake connect face be provided with the welding of quadrangle end plate be the junction plate 4 (Fig. 1) that square frame shape, periphery and quadrangle end plate coincide, the weld part 3 that end plate and junction plate weld; Weld part 5 with the welding of two junction plate other ends; The cross section is right-angled trapezium or right-angled triangle, replenishes plate 7 every the tension of a segment distance and end plate and the tight welding of junction plate.
The weld part of described quadrangle end plate and junction plate welding is bevel for welding 8 places around the quadrangle end plate.Described junction plate 4 thickness are 20-60MM.
Bevel for welding 3-5MM place on the described two quadrangle end plates around end plate is provided with a circle welding stress welding arc fluting 9 (Fig. 2).The degree of depth of described welding stress welding arc fluting 9 is 3-6MM, width 5-7MM.
Described tension is replenished plate and end plate and the tight weld part of junction plate and is established bevel for welding, and groove is 40-60 degree (not drawing among the figure).
Described weld part with two junction plate other ends welding is between two junction plates gapped 6.
The utility model is the bevel for welding 3-5MM place around the end plate on two quadrangle end plates, establish a circle welding stress welding arc fluting 9 after, the high temperature when making welding between end plate and the junction plate obtains cushioning in groove, at high temperature is out of shape to avoid end plate.End plate below stake 1 peripheral hardware cuff 10.
