Abstract
The utility model provides a pull-out test steel hoop for a prestressed concrete pipe pile. The pull-out test steel hoop consists of two semicircular steel hoops and two bolts, wherein two sides of the steel hoops are respectively provided with fastening plates; screw holes are formed in the fastening plates; and the bolts penetrate through the screw holes in the fastening plates and fixedly clamp a pull-out test pile. By adoption of the semicircular steel hoops, the bolts are fixed on the pull-out test pile, the up-pull load is transmitted through the friction force between the steel hoop and the pipe pile, and the problem that the prestressed concrete pipe pile cannot be tested due to an extremely low reinforcement ratio is solved.
Description
Technical field
The utility model provides a kind of prestressing concrete pipe pile to test stirrup with resistance to plucking, is used for the test of prestressing concrete pipe pile resistance to plucking, belongs to constructional materials experimental technique field.
Background technology
When prestressing concrete pipe pile need carry out the resistance to plucking test; Because of its reinforcement ratio is very little, institute joins the total stretching resistance of reinforcing bar and can not satisfy test requirements document, therefore; Can some bear the stake of uplift resistance satisfy the designing requirement of uplift resistance; Just can't make an experiment, or test when not reaching the load of designing requirement reinforcing bar just broken, do not reach the result of the test of expection.
Summary of the invention
The utility model provides a kind of prestressing concrete pipe pile to test stirrup with resistance to plucking, has solved prestressing concrete pipe pile because of the very little problem that can't make an experiment of its reinforcement ratio.
The resistance to plucking test stirrup that the utility model provides adopts following structure:
Two semicircle stirrups and two bolts constitute, and wherein, the both sides of stirrup are respectively equipped with mounting plate, and mounting plate is provided with screw, and the screw that bolt passes on the mounting plate constitutes the relation of fixed connection.
Two semicircle stirrups are installed on the resistance to plucking test pile, and stirrup tightly are fixed on the resistance to plucking test pile, transmit the load that pulls out, accomplish the resistance to plucking test of prestressing concrete pipe pile through the frictional force between stirrup and the resistance to plucking test pile with high-strength bolt.
The good effect of the utility model is:Adopt the half rounds cuff structure, on the resistance to plucking test pile, transmit the load that pulls out, solved prestressing concrete pipe pile because of the very little problem that can't make an experiment of its reinforcement ratio through the frictional force between stirrup and the pile tube through bolt.
Description of drawings
Fig. 1 is the utility model structure principle chart;
Among the figure, 1, mounting plate; 2, bolt; 3, stirrup; 4, resistance to plucking test pile.
The specific embodiment
According to shown in Figure 1; The utility model comprises that two semicircle stirrups 3 and two bolts 2 constitute, wherein, and according to the diameter of pile for prestressed pipe; Cut open along diameter with the thick walled steel tube of same diameter and to make stirrup 2; A mounting plate 1 is respectively welded on the both sides of stirrup 2 respectively, and mounting plate 1 is provided with screw, and the screw that bolt 2 passes on the mounting plate 2 is fixedly clamped resistance to plucking test pile 4.
Claims (1)
