Description

Unidirectional template reinforcing screw Technical Field The utility model relates to the technical field of reinforcing screws, in particular to a unidirectional template reinforcing screw. Background In cast-in-place concrete structures, it is often necessary to reinforce the form with counter-pulling screws that extend through both sides of the entire concrete structure and from the form, with fasteners mounted on both ends of the screw that extend to limit the form's position to strengthen the form. When some reinforced bars are dense or the reinforced bars are blocked by the steel structures and the like, the threaded rods cannot be penetrated, and at the moment, the threaded rods can only be welded on the reinforced bars or other structures to extend out of the templates unidirectionally, so that the templates are reinforced. The template reinforced by the method is easy to break or separate when dealing with larger pressure, and the die is exploded. Disclosure of utility model The invention aims to provide a unidirectional template reinforcing screw rod, which solves the problem that a screw rod welding point is broken or separated. In order to solve the technical problems, the utility model is realized by the following technical scheme: The utility model relates to a unidirectional template reinforcing screw rod which comprises a sleeve and an inner pipe body, wherein the sleeve is provided with an inner thread, the inner pipe body comprises a thread sleeve, the thread sleeve is matched with the inner thread of the sleeve, a steel wire rope is arranged in the thread sleeve, the end part of the steel wire rope is arranged on a cover head, and the cover head is matched and arranged in a port of the thread sleeve; The sleeve is inserted into the die holes aligned with the die plates, so that sleeve installation is realized; The screws oppositely penetrate through two sides of the whole concrete structure and extend out of the formwork, and the effect of limiting the position of the formwork to strengthen the formwork is achieved by installing fasteners at two ends of the extending screw. When some reinforced bars are dense or the reinforced bars are blocked by the steel structures and the like, the threaded rods cannot be penetrated, and at the moment, the threaded rods can only be welded on the reinforced bars or other structures to extend out of the templates unidirectionally, so that the templates are reinforced. The template reinforced by the method is easy to break or separate when dealing with larger pressure, and the die is exploded. The steel wire rope is sleeved on the outer side of the steel bar, so that the connection of the templates is realized, the problem that the screw rod cannot be penetrated is solved, and the installation of the unidirectional templates is realized. Further, a notch is formed in one end of the sleeve, the sleeve is installed in a die hole of the die plate, and the notch is clamped on the outer side of a reinforcing steel bar in the die hole; in the installation process, the sleeve is clamped on the outer side of the steel bar through the notch, so that the sleeve is inserted into the die holes aligned with the templates, and the alignment of the two die holes is realized. Further, a convex ring is arranged at the other end of the sleeve, and the convex ring is in limit fit with a die hole port of the die plate; The installation depth of the sleeve is limited by the cooperation of the convex ring and the edge of the die hole. Further, a prism is arranged at the end part of the threaded sleeve and is in limit fit with the port of the sleeve, a stepped hole is formed in the port of the prism, and the cover head is installed in the stepped hole in a matched mode; The limiting sleeve is matched with the threaded sleeve through threads, the limiting sleeve is clamped on the outer side of the prism through a wrench, the threaded sleeve is driven to rotate, the distance between the prism and the limiting sleeve port is changed through screwing out of the threaded sleeve, and therefore the cover head is pushed to move outwards. Further, two relatively distributed groove bodies are formed in the peripheral side face of the cover head, the end parts of the steel wire ropes are located on the groove bodies, and plugs are fixed at the end parts of the steel wire ropes extending out of the groove bodies; the end face of the cover head is a concave face, and the end part of the plug is in contact with the concave face.
