Abstract

The invention provides an inner supporting device for a reinforcement cage of an extra-high pressure cast-in-place pile foundation and relates to the technical field of reinforcement cage manufacturing. The inner supporting device is used for increasing the processing efficiency of the reinforcement cage and solving the problem that a supporting rod cannot be reused when a welding supporting rod mode is adopted for supporting a stirrup. The inner supporting device for the reinforcement cage of the extra-high pressure cast-in-place pile foundation is characterized in that a sliding rod is driven by a motor and a driving assembly to linearly slide so as to realize the stretching of the sliding rod; a supporting plate at a free end of the stretching sliding rod is in contact with the inner side of the stirrup; a spring is arranged between the free end of the sliding rod and the supporting plate; the arrangement of the spring can compensate for the measuring error caused by the stirrup manufacturing, can ensure the tight contact between the supporting plate and the stirrup and can excellently ensure the supporting for the stirrup. After the supporting device is used, the motor can be driven to reversely act, so that the sliding rod can contract and can be reused. The labor capacity of welding and fixing, and then gas-cutting and detaching in the prior art is avoided and the unnecessary waste of resources is avoided.

Description

technical field [0001] The invention relates to the technical field of reinforcement cage production, in particular to an internal support device for supporting steel bars when the reinforcement cage for cast-in-place pile foundations is manufactured. Background technique [0002] In the process of electric power construction, the foundation may be required to be piled according to requirements. The method is to use machine punching and water mill drilling, and the hole depth meets the design requirements, then lower the reinforcement cage to the pile hole, and then insert the conduit for concrete pouring. The reinforcement cage mainly acts as a tensile force. The compressive strength of concrete is high but the tensile strength is very low. The setting of the reinforcement cage acts as a constraint on the concrete of the pile body so that it can withstand a certain horizontal force. like figure 1 , figure 2 As shown, the reinforcement cage is composed of stirrups 1 and s...
