Abstract
The invention discloses a reinforced masonry rebar straight threaded sleeve connecting wrench and a supporting round nut. The wrench comprises a handle, a semicircular wrench head, an adjusting bolt and the supporting round nut, and is characterized in that the lower end of the semicircular wrench head is connected with the handle, and the semicircular wrench head at the front end of the handle is provide with the regulating bolt capable of rotating on the semicircular wrench head; a wedge-shaped clamping part is connected to the inner side of the upper end of the semicircular wrench head; the round nut is composed of 8-18 sawtooth-shaped fixture blocks which are evenly arranged on the upper end of a circular ring, the tooth shape of the fixture blocks is consistent with that of the wrench clamping part, and the clamping part can be inserted between two sawtooth-shaped fixture blocks and is occluded with the two sawtooth-shaped fixture blocks; and the regulating bolt can be regulated to be adjacent to the circular ring at the lower end of the round nut according to the diameter size of the round nut, thus the contact point is matched with the occlusive part to apply torque on the round nut. The invention can be flexibly used in narrow spaces, lowers engineering cost and is convenient and practical.
Description
Technical field: the present invention relates to a kind of spanner and connector matching used, particularly be used in the interior low-angle use of small space with it.
Background technology: during reinforced masonry engineering construction at present, longitudinal reinforcement can only connect in the small space of building block clean-out hatch, and adopt general tool can't reinforcing bar be welded or mechanical connection, can only adopt single-point colligation overlap joint at present, can not satisfy the requirement of current specifications, thereby restricted the range of application of reinforced masonry engineering, overlap joint connects also wastes steel, has increased engineering cost accordingly.
Summary of the invention: the purpose of this invention is to provide a kind of reinforced masonry steel bar straight thread sleeve connecting spanner and matching used round nut that in small space, uses flexibly in the low-angle use, can reduce engineering cost.Spanner of the present invention comprises handle, semi-circular spanner, regulate bolt, fastener, also comprise and the matching used round nut of spanner, be characterized in: the lower end of semi-circular spanner is connected with handle, the adjusting bolt that can rotate is thereon arranged on the semi-circular spanner of handle front end, the inboard of semi-circular spanner upper end is connected with fastener, fastener is a wedge, round nut is to be provided with 8-18 zigzag fixture block uniformly in the annulus upper end to constitute, the profile of tooth of the fixture block of round nut upper end and the profile of tooth of spanner fastener match, fastener can be inserted between two profile of tooth fixture blocks and its interlock mutually, regulate bolt according to the round nut diameter, be adjusted to the annulus joint with the round nut lower end, this moment, contact point cooperated with interlock place on moment loading and the round nut.The present invention is owing to have equally distributed a plurality of sawtooth on the round nut, so spanner once can low-anglely rotate, rotation and so forth can make spanner use flexibly in small space, has reduced engineering cost, and is convenient and practical.Regulating bolt can regulate according to the size of zigzag round nut, uses with the reinforcing bar that is fit to different-diameter.
