Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and specifically to a device for extending the rebar hole of an anti-buoyancy anchor rod. Background Technology

[0002] For deep foundations located below the groundwater level, the ability of the building structure to resist the buoyancy caused by the groundwater is a crucial factor affecting the structure's safety. The increasingly widespread use of anti-buoyancy anchors has effectively addressed the problem of weak structural buoyancy resistance.

[0003] Anti-buoyancy measures for structures can be categorized into four types: counterweight, anchoring, using external supports, and diversion. Anti-buoyancy anchors are one of the most cost-effective methods. Anti-buoyancy anchors primarily use tensile force to reduce the buoyancy of groundwater on the structure, thus ensuring structural safety. When the internal support structure and the foundation layer are relatively low, it is impossible to fabricate and hoist the entire structure in one piece, causing significant difficulties for on-site construction. Therefore, segmented fabrication is necessary, with connections made at the anchor holes.

[0004] Currently, anti-buoyancy anchor bars are mainly manufactured by inserting whole pieces into the hole. There is no suitable method for construction in situations where whole pieces cannot be inserted into the hole and segmented connections are required. This leads to poor construction quality of straight threaded connections of the bars, difficulties in on-site connection, and low construction accuracy, which seriously affects the anti-buoyancy bearing capacity of the base plate. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a device for extending the rebar hole of an anti-buoyancy anchor rod. By setting a fixed bracket, the upper anchor rod and the lower anchor rod are fixed by the fixed bracket and the upper support frame. Then, the connecting sleeve is screwed on to connect the upper anchor rod and the lower anchor rod, so as to solve the problem of difficult on-site docking.

[0006] The technical solution to achieve the above objective is a rebar extension device for anti-buoyancy anchor bolts, used to connect upper anchor bolts and upper anchor bolts. The extension device includes:

Then, the limiting rod is passed through the locking holes of the two locking blocks, and the limiting rod passes through the gap of the lower anchor rod 2. The lower anchor rod 2 is lowered so that the limiting rod abuts against the lower part of the locking block. After the upper anchor rod 3 and the lower anchor rod 2 are connected, the limiting rod can be pulled out to release the limiting rod from abutting against the locking block.
