Embodiment Construction

[0029] The main implementation mode of this patent is: the connecting punch (2) and the connecting locking sleeve (3) are respectively installed at the ends of the two steel bars (1) that need to be connected; (5) Install it into the connection lock sleeve (3); then use the elasticity of the spring coil (4-2) in the spring control block (4) to install the spring control block (4) into the connection lock sleeve ( 3), and the stable spring (5) provides continuous upward support to ensure the stability and position of the spring control block (4); the conical surface (2-4) at the front end of the connecting punch (2) provides a soothing Stretch the horizontal thrust of the spring control block (4); at this time, the steel wire that stabilizes the top of the spring (5-1) horizontally expands or retracts inwards can provide a stable support surface for the spring control block (4) to move horizontally. After the punch (2) reaches the limit (7), stabilize the compression reaction f...

Abstract

The invention discloses a manual butt-joint locking steel bar connector which is simple in structure, convenient to operate, reliable in connection and free of special tools for installation. Building prefabricated parts and a steel bar cage which are provided with the connector can achieve splicing construction which can immediately bear design loads on splicing sections like building blocks on a construction site. The manual butt-joint locking steel bar connector is mainly composed of a connecting punch, a connecting locking sleeve, a spring control block and a stabilizing spring. The connecting punch and the connecting locking sleeve are installed at the ends of steel bars of two parts needing butt joint respectively. The stabilizing spring and the spring control block are arranged in the connecting locking sleeve. When the connector is in butt joint, the spring control block is opened by the conical face at the front end of the connecting punch. After the connecting punch reaches the limiting position, the spring control block contracts, the neck of the connecting punch is clamped, and the purpose of steel bar connection is achieved.

Description

technical field [0001] The invention belongs to construction hardware or mechanical hardware in the field of construction engineering, in particular to a manual butt locking steel bar connector. The invention is suitable for on-site splicing of prefabricated buildings, connection of reinforced concrete prefabricated components, and on-site splicing of cast-in-place concrete reinforcement cages. Background technique [0002] In order to improve the construction efficiency of construction projects, promote the development of construction mechanization and standardization, and reduce the impact of construction site construction on the surrounding environment and society, it is necessary to do a good job of factory-produced finished products and go to the construction site for installation and splicing. The main force-bearing structure of the building is mainly composed of steel bars and concrete, and the steel bar connection technology in the reinforced concrete structure is un...
