Another type of releasable sling is formed by a control cable, in particular:
the movable end of the control steel cable passes through one longitudinal suspender and then passes through the lifting lug on the reinforcement cage, and finally passes out of the other longitudinal suspender, and the movable end of the control steel cable is fixed on the anchoring head above the pile hole.
Preferably, the longitudinal suspenders are symmetrically arranged at two sides of the pile hole.
In order to adapt to the conditions of different diameters and the depth of the steel reinforcement cage, the longitudinal suspender and the steel reinforcement cage are provided with a plurality of through holes, and the bolt is inserted into the through holes to connect the longitudinal suspender and the steel reinforcement cage into a whole; the longitudinal suspender is a multi-section structure which is connected into a whole through a threaded nut;
the longitudinal suspender adopts a steel pipe.
The utility model has the advantages that:
(1) The utility model can avoid the processes of welding and overlapping the hanging bar for many times in the past hoisting process, reduces the installation operation steps such as welding and the like, and can accelerate the construction speed; (2) The rigidity of the steel pipe suspender is larger than that of a currently commonly used suspender, so that the perpendicularity of the steel reinforcement cage can be better controlled; (3) Due to the adoption of the releasable hanging ring structure, the steel reinforcement cage is released through the control steel cable, and then the longitudinal hanging rod is recovered, so that materials are saved, the construction process is slowed down, the steel reinforcement cage does not need to be welded with hanging bars, and the quality of the steel reinforcement cage is ensured.

FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic view of the structure of the control cable when it is directly formed into a releasable sling;
FIG. 3 is a schematic view of an alternative releasable sling;
in the figure, 1 is a cage steel pipe, 2 is an anchor head, 3 is a control steel cable, 4 is a longitudinal suspender, 5 is a through hole, 6 is a releasable suspending ring, 7 is a steel reinforcement cage, 8 is the ground, and 9 is a pile hole.
Detailed Description
The utility model is specifically described below with reference to the accompanying drawings, as shown in the drawings, a transverse cage steel pipe 1 is arranged above the pile hole 9, and the cage steel pipe 1 is in shaft connection with the upper ends of 2 longitudinal suspenders 4; the lower end of the longitudinal boom 4 is connected with a releasable lifting ring 6, the reinforcement cage 7 is connected with the releasable lifting ring 6, and the releasable lifting ring 6 is connected with the control steel rope 3.
As shown in fig. 3, the releasable hanging ring comprises a hanging hook 61, one end of the hanging hook 61 is in shaft connection with one side 41 of the lower end of the longitudinal hanging rod, the other end of the hanging hook 61 is in abutting connection with the inner side of a baffle plate 42, the upper end of the baffle plate 42 passes through a guide seat 43 on the other side of the longitudinal hanging rod and then is connected with the lower end of a control steel rope 3, the upper end of the baffle plate 42 is in abutting connection with the lower end of a spring 44, the spring 44 is sleeved on the control steel rope 3, and the upper end of the spring is fixed on a spring seat 45; the principle of the structure is as follows: when the other side of the lifting hook 61 is abutted against the inner side of the baffle plate 42, the lifting hook cannot rotate, and at the moment, the lifting lug 71 of the reinforcement cage is arranged on the lifting hook 61; when the control steel cable is pulled up under the action of external force, the baffle moves upwards, and the movable end of the lifting hook 61 is not blocked by the baffle and the lifting hook naturally rotates downwards under the action of gravity of the reinforcement cage, so that the reinforcement cage is released; the function of the spring is to ensure that the baffle is always under the action of elasticity to be abutted with the movable end of the lifting hook under the condition that the control steel cable is not subjected to external force.
As shown in fig. 2, another releasable sling is formed by a control cable, specifically:
the movable end of the control steel rope 3 passes through one longitudinal suspender and then passes through a lifting lug 71 on the reinforcement cage, and finally passes out of the other longitudinal suspender, and the movable end of the control steel rope is fixed on the anchoring head 2 above the pile hole. The disadvantages of this structure are: since the mass of the reinforcement cage is entirely suspended from the control cable, the control cable is required to have high strength.
Preferably, the longitudinal suspenders are symmetrically arranged at two sides of the pile hole.
In order to adapt to the conditions of different diameters and the depth of the steel reinforcement cage, the longitudinal suspender and the steel reinforcement cage are provided with a plurality of through holes 5, and bolts are inserted into the through holes to connect the longitudinal suspender and the steel reinforcement cage into a whole; the longitudinal suspender is a multi-section structure which is connected into a whole through a threaded nut;
the longitudinal suspender adopts a steel pipe.
The utility model prevents the steel reinforcement cage from floating upwards by pressing the longitudinal suspender; in addition, after the construction is completed, the longitudinal suspender can be recycled, so that materials are saved, the steel reinforcement cage does not need to be welded with hanging bars, and the quality of the steel reinforcement cage is ensured.
