An anchor rod construction device for construction engineering

Abstract

The invention discloses a bolt construction device for construction engineering, which comprises a stabilizer, a base rod, a connecting sleeve and a connecting rod, the base rod, the connecting sleeve and the connecting rod are fixedly connected by bolts, and the inner surface of the stabilizer is fixedly installed There is a directional cylinder, the inner surface of the directional cylinder is slidingly connected with the outer surface of the connecting sleeve, the left and right sides of the directional cylinder are screwed with positioning bolts, one end of the positioning bolt is in conflict with the outer surface of the connecting sleeve, and the inner surface of the connecting sleeve is in contact with the base The outer surface of a rod is slidingly connected, and the invention relates to the technical field of building construction. The bolt construction device used in this construction project uses a stabilizer and a directional cylinder to ensure the accuracy of the drilling position, uses a simple flange fixing structure to fix the structure, and then cooperates with the grouting hole to inject cement slurry into the base rod, connecting sleeve and connecting rod , and use reinforced threaded rods to improve the supporting strength, simple structure, convenient grouting, not only uniform grouting, but also low cost.

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 ...
