The invention provides a 220kV live work with a carbon fiber plate big knife clamp, including a front clamp, a rear clamp, an insulating pull rod and a wire tensioner, the insulation pull rod is connected with the wire tightener, and the first clamp body and the second clamp body use carbon fiber The carbon fiber sheet includes at least two carbon fiber cloth layers and at least one carbon fiber filament layer, the carbon fiber filament layer is located between the two carbon fiber cloth layers, and the carbon fiber cloth layer is one layer of longitudinal carbon fiber and transverse carbon fiber. The vertical carbon fiber and the horizontal carbon fiber have the same fiber width, and the carbon fiber layer is bidirectionally interwoven with carbon fiber, and the carbon fiber cloth layer and the carbon fiber layer are impregnated with a binder. Strong durability, no rust, can be used in high acid, alkali, salt and atmospheric corrosion environment, also has the advantages of high fatigue resistance, wear resistance, anti-aging and so on.

The invention belongs to the technical field of external wall construction of building structures, and provides a quick-dismantling building formwork and a light-weight cast-in-place wall body construction method. The quick-dismantling building formwork comprises panels, rib plate groove beams and docking purlines. The rib plate groove beams comprise a plurality of transverse rib plate groove beams and a plurality of longitudinal rib plate groove beams, wherein the transverse rib plate groove beams and the longitudinal rib plate groove beams are arranged at the rear side of the panels in a crossing mode. The docking purlines are matched and clamped in the rib plate groove beams in a sliding mode, locking pieces are arranged between the docking purlines and the rib plate groove beams, and when the docking purlines are moved in place, the locking pieces are used for locking the docking purlines. The quick-dismantling building formwork is reasonable in structural design, light in weight and high in strength, can quickly assemble large-area flat formworks, inside corner formworks and external corner formworks, and effectively solves the problems of low efficiency and high labor intensity of the traditional formwork assembling construction, and meanwhile, the construction of the light-weight cast-in-place wall body has the advantages of high construction efficiency, good construction effect and effective guarantee of wall body quality.
