It connects, is equipped with pulling fixing piece on the surface exterior wall for thickening steel plate and exterior wall connecting portion and on overhanging I-steel, it is special
Sign is: further including the drawknot component that will overhang I-steel and the fixed drawknot of exterior wall, the drawknot component includes by four reinforcing bars
The square frame of composition, the square frame is two groups, at the both ends of two groups of square frames disposed in parallel along drawknot
Direction is respectively equipped with fixation steel plate, and the central location of the fixation steel plate is respectively provided with the threaded rod for adjusting drawknot intensity,
One end of the threaded rod is screwed with fixation steel plate respectively to be connect, and the other end is respectively equipped with welding steel, the welding steel
Plate passes through drawknot bolt respectively and is fixedly connected with the pulling fixing piece overhang on I-steel and exterior wall.
Further, the overhanging I-steel is connect by welding manner with steel plate is thickeied, and the drawknot on the exterior wall is solid
Determine part to be fixedly connected by thickening steel plate with outer wall screw, the pulling fixing piece on the overhanging I-steel is by welding
It is fixedly connected with overhanging I-steel, the fixation steel plate is connect with square frame by welding, and the reinforcing bar is spiral shell
Line steel.
The beneficial effect for exterior wall builder's jack drawknot structure that the utility model is adjustable is: steel plate is thickeied by being equipped with, it will
Being fixedly connected by high-strength bolt with exterior wall for overhanging I-steel, without reserving I-steel hole in exterior wall, avoids and tears open
After unloading I-steel, holes blocking leakiness causes the generation of water leakage situation, meanwhile, without cutting off I-steel, can all dismantle
It reuses, substantially increases the utilization rate of I-steel.By the way that adjustable drawknot component is arranged, by precession or screw out threaded rod come
Drawknot intensity is adjusted, the safe handling function of builder's jack has been effectively ensured.The utility model structure is simple, securely and reliably,
Fastness is high, and construction cost is low, and construction efficiency is high, is worthy of popularization.
