Embodiment 1

[0025] Such as Figure 1 to Figure 2 As shown, an F-shaped standard frame for installing and disassembling prefabricated beam formwork includes two F-shaped support frames arranged in parallel and a connecting rib 1 for fixedly connecting the two F-shaped support frames. Each F-shaped support frame Both include vertical ribs 2, the top right side of each vertical rib 2 is fixedly connected with a boom 3, the middle right side of each vertical rib 2 is fixedly connected with a support arm 4, and the upper surface of the support arm 4 The upper part is fixedly connected with a corner 41 which engages with the outer transverse rib of the prefabricated beam formwork, and the bottom right side of the two vertical ribs 2 is jointly fixedly connected with a back brace 5 . There are four connecting ribs 1, of which two connecting ribs 1 are respectively arranged at the top side end and the middle part of the two vertical ribs 2, and the other two connecting ribs 1 are respectively arr...

Embodiment 2

[0032] A construction method for an F-type standard frame used to assemble and disassemble a prefabricated beam formwork, comprising the following steps:

[0033] Step 1. Use the hook of the gantry crane to hook the lifting lug 11, and hang the F-shaped standard frame to the outside of the prefabricated beam formwork;

[0034] Step 2, two F-shaped support frames are clamped between two adjacent longitudinal ribs on the outside of the prefabricated beam formwork, and the two vertical ribs 2 are closely attached to the outer wall of the prefabricated beam formwork;

[0035] Step 3. Slowly control the gantry crane to lift, so that the clamping angle 41 on the support arm 4 is closely engaged with the outer transverse rib of the prefabricated beam formwork;

[0036] Step 4. Continue to slowly control the gantry crane to lift, and use the self-gravity of the prefabricated beam formwork to engage the back support 5 with the formwork below the prefabricated beam, so as to ensure that...

Abstract

The invention discloses an F-shaped standard frame for assembly and disassembly of a prefabricated beam formwork and a construction method and belongs to the technical field of efficient assembly anddisassembly of prefabricated beam formworks. According to the construction method, the F-shaped standard frame is welded and assembled with I-steel, and the F-shaped standard frame cooperates with a beam plant gantry crane to transfer the formwork, and the method can rapidly and effectively improve the formwork disassembly and assembly efficiency; besides, action force is exerted on a cross rib inthe formwork, and therefore the safety risk caused by a long load distance, rotation and the like in the formwork transferring process can be lowered. Firstly, the machined standard frame is conveyedto below a formwork needing disassembly (assembly) through the gantry crane; then, workers cooperate with the gantry crane to clamp the standard frame at the cross rib on the outer side of the formwork and detect whether the standard frame is firm or not, the gantry crane is adopted to convey the formwork to an operation platform, and the operations are sequentially and circularly conducted untilthe task is completed. The F-shaped standard frame for assembly and disassembly of the prefabricated beam formwork achieves the effects of lowering safety risk, reducing damage to the formwork, improving construction efficiency, accelerating construction progress and then lowering construction cost.

Description

technical field [0001] The invention belongs to the technical field of efficient assembly and disassembly of prefabricated beam formwork, and in particular relates to an F-shaped standard frame and a construction method for assembling and disassembling prefabricated beam formwork. Background technique [0002] Conventional prefabricated beam formwork transfer is a construction process in which the gantry crane transports the formwork itself through steel wire ropes and hooks; or for the convenience of transportation, the adjacent vertical hard ribs of the formwork are welded into a whole by horizontal industrial steel, and the gantry crane hook passes through A construction technique for transporting formwork by fastening with welded transverse ribs. [0003] The construction technology of transferring the formwork through the formwork itself, or the construction technology of transferring the formwork through the horizontal steel welding on the adjacent vertical hard ribs o...
