Description

Technical Field

[0001] This invention relates to the field of precast beam formwork dismantling technology, specifically to a device for dismantling inner and outer formwork after the casting of box-type precast beams. Background Technology

[0002] Precast beams are beams that are prefabricated in a factory and then transported to the construction site for installation and fixing according to design requirements. They have a wide range of applications. After the box-type precast beams are poured, their internal and external formwork needs to be dismantled. Therefore, internal and external formwork dismantling equipment is needed to assist workers in dismantling the beams, in order to save manpower and time. However, current internal and external formwork dismantling equipment still has some shortcomings, such as: 1. The equipment for removing internal and external formwork cannot remove internal and external formwork simultaneously; 2. The equipment for dismantling internal and external formwork is not convenient for hoisting and transportation; 3. The internal and external formwork removal equipment is not convenient for removing formwork in different locations; Therefore, the existing equipment for removing the inner and outer formwork after the casting of box-type precast beams needs to be improved. Summary of the Invention

[0003] The purpose of this invention is to provide a device for removing inner and outer formwork after the casting of box-type precast beams, so as to solve the problems mentioned in the background art that the current inner and outer formwork removal devices on the market cannot remove inner and outer formwork simultaneously, are inconvenient for hoisting and transportation, and are inconvenient for removing formwork at different locations.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a device for removing inner and outer formwork after casting a box-type precast beam, comprising: The base has buffer grooves on both sides, and a rotating shaft is installed inside the buffer groove. The rotating shaft is movably connected to an electric lifting rod, and the end of the electric lifting rod away from the rotating shaft is fixed to a pressure plate. The pressure plate is used to push the inner and outer templates of the precast beam to be disassembled. A horizontal plate is fixed to one side surface of the electric telescopic rod, and a positioning hole is provided in the middle of the horizontal plate. A positioning plate is fixed above the base near the buffer groove, and a limit hole is provided in the middle of the positioning plate. A limit block passes through the limit hole and mates with the positioning hole.

[0005] Preferably, the electric telescopic rods are symmetrically distributed about the center line of the base, and the electric telescopic rods form a rotating structure with the base through a rotating shaft. The opening and retraction of the electric telescopic rods can be completed through the rotating structure between the electric telescopic rods and the rotating shaft.

[0006] Preferably, the positioning hole and the limiting hole are the same size, and the size of the positioning hole matches the size of the bottom of the limiting block. The limiting block is used to pass through the limiting hole and the positioning hole from top to bottom, and then the limiting block is rotated 90° to complete the fixing of the electric telescopic rod.

[0007] Preferably, the base has a threaded hole on its surface, a connecting post is provided inside the threaded hole, one end of the connecting post is fixed to the hoisting block, and a through hole is provided in the middle of the hoisting block, which can be used to connect with the crane's rope.

[0008] Preferably, the lifting blocks are symmetrically distributed about the center line of the base, and the outer wall of the connecting column is threaded. The connecting column and the threaded hole form a threaded connection. By connecting the lifting equipment rope with the lifting block, the lifting effect can be facilitated.

[0009] Preferably, pulleys are installed on the side of the base away from the connecting column, and the pulleys are evenly distributed about the base. When the device is on top of the precast beam, the position of the electric lifting rod can also be changed by moving the base through the pulleys, thereby facilitating the disassembly of the template at different positions.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the inner and outer formwork removal equipment after the box-type precast beam is poured opens the electric lifting rod by rotating the shaft, and then the limiting block passes through the limiting hole and the positioning hole from top to bottom in sequence. Then the limiting block is rotated 90° to fix the electric lifting rod. The position of the electric lifting rod is changed by moving the base through the pulley, thereby achieving the effect of facilitating the disassembly of the formwork at different positions.

[0011] 1. The equipment for removing the inner and outer formwork after the box-type precast beam is poured uses a rotating shaft to open the electric lifting rod, so that the horizontal plate fixed on the surface of the electric lifting rod is located below the positioning plate. Then, the limiting block is used to pass through the limiting hole and the positioning hole from top to bottom. Then, the limiting block is rotated 90° to fix the electric lifting rod. The electric lifting rod is started to drive the pressure plate to move outward and finally push the inner and outer formwork, thereby achieving the effect of disassembling the inner and outer formwork at the same time. 2. The equipment for removing the inner and outer formwork after the box-type precast beam is poured involves connecting the connecting column fixed at one end of the hoisting block with the threaded hole opened on the surface of the base. The hoisting block can be fixed by rotating it. Then, the removal equipment can be transported to the top of the poured precast beam by the hoisting equipment, thereby facilitating the hoisting and transportation of the equipment. 3. The equipment for removing the inner and outer formwork after the box-type precast beam is poured can be moved easily by the pulleys installed at the bottom of the base. When the equipment is on top of the precast beam, the position of the electric lifting rod can also be changed by moving the base through the pulleys, thereby facilitating the disassembly of the formwork at different positions.

[0015] Please see Figure 1-3 This invention provides a technical solution: a device for removing inner and outer formwork after casting a box-type precast beam, comprising: a base 1, buffer grooves 2 on both sides of the base 1, and a rotating shaft 3 installed inside the buffer grooves 2, the rotating shaft 3 being movably connected to an electric lifting rod 4, and the end of the electric lifting rod 4 away from the rotating shaft 3 being fixed to a pressure plate 5, and the pressure plate 5 being used to push and remove the inner and outer formwork of the precast beam; a horizontal plate 6, fixed to one side surface of the electric lifting rod 4, and a positioning hole 7 being provided in the middle of the horizontal plate 6; a positioning plate 8 fixed above the base 1 near the buffer grooves 2, and a limiting hole 9 being provided in the middle of the positioning plate 8, and a limiting block 10 passing through the limiting hole 9 and engaging with the positioning hole 7.

[0016] The electric telescopic rod 4 is symmetrically distributed about the center line of the base 1, and the electric telescopic rod 4 forms a rotating structure with the base 1 through the rotating shaft 3; the positioning hole 7 and the limiting hole 9 are the same size, and the size of the positioning hole 7 matches the size of the bottom of the limiting block 10.

[0017] The electric telescopic rod 4 is opened by rotating the pivot 3, so that the horizontal plate 6 fixed on the surface of the electric telescopic rod 4 is located below the positioning plate 8. Then, the limiting block 10 passes through the limiting hole 9 and the positioning hole 7 from top to bottom. Then, the limiting block 10 is rotated 90° to fix the electric telescopic rod 4. The electric telescopic rod 4 is started to drive the pressure plate 5 to move outward and finally push the inner and outer templates, thereby achieving the effect of disassembling the inner and outer templates at the same time.

[0018] The surface of the base 1 is provided with a threaded hole 11, and a connecting post 12 is provided inside the threaded hole 11. One end of the connecting post 12 is fixed to the hoisting block 13, and a through hole 14 is provided in the middle of the hoisting block 13.
