Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a protective device for disassembling a rigid back bolster. Background Art

[0002] The steel back bolster replaces the wooden square and steel pipe in the traditional formwork process, and at the same time solves many problems existing in the traditional reinforcement construction. The new steel back bolster support system is forged from high-quality steel. The main wall keel can be telescopically adjusted through connectors, and the steel secondary keel can be customized in specification standards, which can meet the universality of different floor heights and internal and external wall support materials. However, in the disassembly construction of the steel back bolster, the following problems still exist:

[0003] Since the steel back bolster itself has a certain weight, when disassembling the steel back bolster, the staff is prone to dropping the steel back bolster due to improper operation. At this time, the dropped steel back bolster is likely to cause property losses to the construction site and is also likely to cause certain injuries to the staff's body.

[0004] In view of the above problems, the utility model document proposes a protective device for disassembling a rigid back bolster. Content of the Utility Model

The sliding seat is slidably connected to both inner walls of the lifting seat;

[0009] A clamping assembly for clamping and fixing the steel back bolster to be disassembled;

[0010] A lifting assembly for adjusting the height of the lifting seat.

[0011] In a possible design, the clamping assembly includes a lower clamping plate fixedly installed on the top of the sliding seat. Two guide rods are fixedly installed on the top of the lower clamping plate. One end of each of the two guide rods slidably penetrates through the same upper clamping plate. Springs are sleeved on the outer walls of the two guide rods. One end of each spring is fixedly connected to the top of the lower clamping plate, and the other end of the spring is fixedly connected to the bottom of the upper clamping plate. A plurality of teeth are fixedly installed on both sides of the lower clamping plate and the upper clamping plate that are close to each other, and the plurality of teeth on the lower clamping plate and the upper clamping plate cooperate with each other.

[0012] In a possible design, the lifting assembly includes an internally threaded tube rotatably connected to the top of the base. A stud is threadedly connected to the inner wall of the internally threaded tube. One end of the stud is fixedly connected to the bottom of the lifting seat.
