Abstract
The utility model discloses an anti-corrosion joint for a prestressed concrete pipe pile, which is characterized by comprising an end plate and a connecting flange, wherein the connecting flange is provided with a rib bracket; the end plate is provided with a plurality of screw holes; the connecting flange is provided with a plurality of bolt insert positions corresponding to the screw holes. After the anti-corrosion joint for a prestressed concrete pipe pile is adopted, the influence of friction and extrusion process of geological environment for the anti-corrosion measures during construction can be avoided, so that the service life of a pipe pile foundation is effectively prolonged, and the safety of a project can be guaranteed; meanwhile, the performances such as shear resistance, bending resistance and the like of a pipe pile connecting structure at the part of the joint can be guaranteed, the connection is stable, and the quality and safety of the pipe pile in the construction and use process can be also guaranteed.
Description
Technical field
The utility model relates to a kind of joint, particularly a kind of prestressed concrete pipe pile corrosion-proof joint.
Background technology
In recent ten years, pile tube is used widely at building field with characteristics such as bearing capacity of single pile are high, construction costs is low, the duration is short.Pile tube is a prefabricated component, in construction, need splice each section pile tube.Along with the expansion of the application of pile tube, the connection between the pile tube is faced with an anticorrosion problem in corrosive environment.Connection between traditional pile tube be through in the groove place electricity consumption weld-ring of pile end board to two pile end boards are integrally welded.Directly welding is because spacing is little between end plate, and weld seam is narrower, welder's level difference; Difficult quality guarantee to construction; Cause potential safety hazard to engineering easily, and the anti-corrosion capability of weld seam is relatively poor, welding back temperature is high; Stake receives powerful frictional force after getting into soil layer, is difficult to carry out effective anti-corrosion measure.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of prestressed concrete pipe pile corrosion-proof joint, and this corrosion-proof joint can be applicable in the various corrosive environments.
The utility model solves the technical scheme that its technical problem adopted:
The prestressed concrete pipe pile corrosion-proof joint is characterized in that it comprises end plate and adpting flange, and said adpting flange is provided with the rib frame, and end plate is provided with some screws, and adpting flange is provided with the interspersed position of some bolts corresponding with screw.
The open slot that a flange is provided with and the interspersed position of bolt is communicated with at place, the interspersed position of bolt.
The connecting portion of end plate and adpting flange is coated with anticorrosive paint, to be suitable for different corrosive environments.
The beneficial effect of the utility model is: the flange of the prestressed concrete pipe pile corrosion-proof joint of top pile tube and the common end plate of bottom pile tube; Link into an integrated entity through connecting bolt; The stretch-draw screwhole position that must stay in flange open slot and the tubular pile production process is consistent, so do not influence the pile tube production technology; The whole connection procedure that pile tube gets into soil layer need not welding, and connector is a conventional fasteners, so can improve efficiency of construction and carry out the connection between the pile tube at an easy rate; Be connected all in the stake external diameter because of bolt simultaneously; Can carry out the surface anticorrosion processing to connector and pile tube coupling part by different environment for use requirements, the friction and Extrusion process of geological environment effectively prolongs the application life of pipe pile foundation to the influence of anti-corrosion measure in the time of can avoiding constructing; Guarantee the safety of engineering; The pile tube syndeton is protected in performances such as the shearing resistance of joint, bending resistances, connects firmly, guarantee the quality and safety in tube pile construction and the use.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is the sectional view of Fig. 2;
Structural representation when Fig. 4 is the utility model use.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3; The prestressed concrete pipe pile corrosion-proof joint; Comprise end plate 1 and adpting flange 2, adpting flange 2 is provided with rib frame 3, and an end of rib frame is provided with the junction plate 4 that is connected with pile tube; End plate 1 is provided with some screws, and adpting flange 2 is provided with some and screw 4 corresponding bolts and interts position 8.
As shown in the figure, for ease of the installation of bolt, the open slot 5 that a flange is provided with and the interspersed position of bolt is communicated with at place, the interspersed position of bolt.
The connecting portion of end plate and adpting flange is coated with different anticorrosive paints to different corrosive environments, and anticorrosive paint is not rubbed in pile tube is driven underground process and pushes and be damaged.
The adpting flange of the utility model is installed in an end of pile tube; Common end plate is installed in the other end of pile tube; When in use pile tube connects, the adpting flange of top pipe pile end portion is docked with the end plate of bottom pipe pile end portion, utilize connecting bolt 9 that adpting flange and end plate are fixed again and get final product.
Because the flange of the prestressed concrete pipe pile corrosion-proof joint of top pile tube 6 and the end plate of bottom pile tube 7 link into an integrated entity through connecting bolt; The stretch-draw screwhole position that must stay in flange open slot and the tubular pile production process is consistent, so do not influence the pile tube production technology; The whole connection procedure of constructing need not welding, and connector is a conventional fasteners, so can improve efficiency of construction and carry out the connection between the pile tube at an easy rate; Be connected all in the stake external diameter because of bolt simultaneously; Can carry out the surface anticorrosion processing to connector and pile tube coupling part by different environment for use requirements, the friction and Extrusion process of geological environment effectively prolongs the application life of pipe pile foundation to the influence of anti-corrosion measure in the time of can avoiding constructing; Guarantee the safety of engineering; Increase performances such as the shearing resistance that the pile tube syndeton goes out at joint, bending resistance greatly with amount, connected firmly, guaranteed the quality and safety in tube pile construction and the use.
