Abstract
The utility model relates to a reinforcing steel bar straight thread sleeve connecting spanner of a reinforcement distribution building body, which comprises a handle, a clamping ring A, a clamping ring B, a semi-ring shaped element A, a semi-ring shaped element B, a rotating shaft, a connecting piece A and a connecting piece B. The characteristics of the reinforcing steel bar straight thread sleeve connecting spanner are as follows: the clamping ring A is fixed at the upper end of the semi-ring shaped element A in a connecting manner, and the clamping ring B is fixed at the upper end of the semi-ring shaped element B in a connecting manner; N concave faces and convex faces are arranged on the inner surfaces of the semi-ring shaped element A and the semi-ring shaped element B, N is an integral multiple of the corner number of nuts to be screwed, and N is larger than 1; the surfaces of the concave faces are lower than the inner surfaces of the clamping ring A and the clamping ring B, so as to avoid sliding-down when in nut screwing; the handle is fixed at the outer side of the semi-ring shaped element B, the connecting piece A is connected at the rear end of the semi-ring shaped element A, and the connecting piece B is connected at the rear end of the semi-ring shaped element B; the front ends of the semi-ring shaped element A and the semi-ring shaped element B are connected by a shaft sleeve of the rotating shaft, and the rear ends are connected by the connecting piece A and the connecting piece B. N concave faces and N convex faces are arranged in the semi-ring shaped elements of a spanner head of the reinforcing steel bar straight thread sleeve connecting spanner, N is the integral multiple of the corner number of the nuts to be screwed, and N is larger than 1; therefore, the spanner is convenient as well as practical, and can be flexibly used in narrow space, and the engineering cost is reduced.
Description
Technical field:
The utility model relates to a kind of reinforced masonry steel bar straight thread sleeve connecting spanner, particularly in low-angle uses.
Background technology:
During reinforced masonry engineering construction at present, it is 60 ° that common wrench cooperates the minimum anglec of rotation of hex nut, reinforced masonry can be 47 ° for the maximum anglec of rotation of bar one-time, so after adopting common wrench to rotate once, can not carry out the rotation second time, thereby, vertical reinforcement can only adopt the lapped configuration form because the space is narrow and small, adopting overlap joint to connect can not be applied in the major diameter reinforcing bar, the major diameter reinforcing bar can only adopt mechanical connection, thereby restricted the range of application of reinforced masonry engineering, overlap joint connects also wastes steel, has increased engineering cost accordingly.
The utility model content:
The purpose of this utility model provides and a kind ofly uses in small space flexibly, be applicable to the major diameter reinforcing bar, can reduce the reinforced masonry steel bar straight thread sleeve connecting spanner of engineering cost.The technical solution of the utility model is: the utility model comprises handle, snap ring A, snap ring B, two semi-circular element half-rings shape element A and semi-circular element B, rotating shaft, connector A, connector B is characterized in: snap ring A is fastened on the upper end of semi-ring element A, and snap ring B is fastened on the upper end of semi-ring element B, the inner surface of semi-circular element A and semi-ring element B is provided with N concave surface and convex surface, N gets the integral multiple of the nut angle number that will tighten, N＞1, and the surface of concave surface will be lower than snap ring A, the inner surface of B, so that it can landing when nutting, handle is fixed on the outside of semi-circular element B, and semi-circular element A rear end is connected with connector A, and the rear end of semi-circular element B is connected with connector B, the front end of semi-circular element A and semi-ring element B is connected by the rotating shaft axle sleeve, and the rear end is connected B together by connector A with connector.The utility model adopts reinforced masonry steel bar straight thread sleeve connecting spanner, owing in the semi-circular element of spanner N concave surface and N convex surface are arranged, N gets the integral multiple of the nut angle number that will tighten, N＞1, so can in small space, use flexibly, reduced engineering cost, convenient and practical.
