Anchor rod construction device for building engineering

Abstract

The invention discloses an anchor rod construction device for building engineering, and relates to the technical filed of building construction. The anchor rod construction device comprises a stabilizing frame, a base rod, a connecting sleeve and a connecting rod, the base rod, the connecting sleeve and the connecting rod are fixedly connected through bolts, a directional cylinder is fixedly installed on the inner surface of the stabilizing cylinder, the inner surface of the directional cylinder is slidably connected with the outer surface of the connecting sleeve, positioning bolts are correspondingly connected to the left and right sides of the directional cylinder in a threaded mode, one ends of the positioning bolts abut against the outer surface of the connecting sleeve, and the innersurface of the connecting sleeve is slidably connected with the outer surface of the base rod. According to the anchor rod construction device for building engineering, the accuracy of the drilling position is ensured by using the stabilizing frame and the directional cylinder, a simple flange fixing structure is utilized to fix the structure, then cement slurry is injected into the base rod, theconnecting sleeve and the connecting rod by being matched with a grouting hole, the stress support strength is increased by using a reinforced threaded rod, the structure is simple grouting is convenient, grouting is uniform, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a bolt construction device for building engineering. Background technique [0002] As a tensile member that goes deep into the ground, the bolt is connected to the engineering structure at one end, and the other end goes deep into the ground. The whole bolt is divided into a free section and an anchor section. Its function is to apply prestress to the anchor rod. The anchor section refers to the area where the cement paste bonds the prestressed tendon to the soil layer. Its function is to increase the bonding friction between the anchor body and the soil layer, increasing the The pressure-bearing effect of the anchor body transmits the tension of the free section to the depth of the soil. The existing anchor rod can only simply perform simple grouting reinforcement on the soil and rock layers, and there is a problem of incomplete reinforcement. After the anchor rod ...
