Hanger and construction method for installing anti-floating anchor rod assembly indoors

Abstract

The invention discloses a lifting frame and a construction method used for installing an anti-floating anchor assembly indoors. The lifting frame comprises a base disk (7), vertical pillars (10), a top frame (11) and a steel wire rope (12) with a lifting hook. The top frame (11) is provided with a fixed pulley (13). The base disk (7) is provided with a weight block (14), an anchor beam (15) and rolling wheels (18). The steel wire rope (12) is fixed through a rope clamping head (17) after bypassing the fixed pulley (13) and the anchor beam (15). The key step of the construction method is that an anchor string section is sunk by using the lifting frame and the steel wire rope (12), and connected with a hole mouth of an anchor hole in a butt joint mode. When the floor height of an indoor space is smaller than the overall height of the assembly, the anti-floating anchor assembly can be installed through the lifting frame and the construction method.

Description

technical field [0001] The invention relates to the construction technology of an anti-floating anchor rod in the field of civil engineering, in particular to an auxiliary hanger and a construction method for installing an anti-floating anchor rod assembly indoors. Background technique [0002] When constructing anti-floating anchors in the prior art, it is necessary to use ropes to bind the grout bag, the hard first grouting pipe, the hard second grouting pipe and the anchor bar into a combination, and then drill the anchor hole and close it. Put the assembly into the hole as a whole, and then carry out secondary grouting through two grouting pipes respectively. [0003] However, in the actual construction process, it was found that the above-mentioned construction method has a technical problem. This method has huge limitations. The length of the combination is generally greater than the floor height, such as the floor height of the underground space is generally about 4m...

AI Technical Summary

Problems solved by technology

However, there are still relatively large defects in this idea: firstly, the steel pipe columns and steel pipe crossbeams of the scaffold are connected by fasteners, the steel pipes and fasteners consume a large amount of materials, the assembly process is slow, the workload is large, and the efficiency is low; and, The scaffolding will occupy the opening of the anchor hole, and occupy the operating space for the workers to splice the last section of the anchor bar; moreover, even if the assembly in the anchor hole is spliced, when it is necessary to construct the next anchor hole, It is necessary to dismantle the scaffolding and re-install the scaffolding in the next anchor hole, which further increases the workload, further reduces the efficiency, and slows down the speed

Moreover, more importantly, the above idea is only to complete the splicing of the anchor bars, as for how to install the grout bag, how to butt the hard grouting pipe and other issues cannot be solved
