Description
Technical Field
The invention relates to an auxiliary anchor net pressing tray capable of flattening an anchor net at a lap joint and conveniently mounting components such as an anchor rod, a self-aligning gasket, an anchor rod nut and the like and an anchor net pressing method.
Background
The exposed length of the thread at the end part of the anchor rod is regulated, so that the length of the thread is longer than the specification of a quality standard, and the length of the thread is shorter than the specification of an anchor rod member which is inconvenient to install. Anchor net overlap joint department overlaps there is 2 ~ 8 layers, and thickness also has 30 ~ 80 millimeters, and the stock tip screw thread of anchor net overlap joint department is blocked by the anchor net, causes the stock tip screw thread to expose length little, and members such as inconvenient installation anchor rod dish, aligning gasket, stock nut, even the installation construction also wastes time and energy by force. Under this condition, constructor throws away stock aligning packing ring for the convenient installation stock nut, and the direct mount stock nut leads to the stock component to be incomplete, and engineering quality is unqualified. The net pressing device and the method which can flatten the anchor net at the lap joint and facilitate the installation of components such as the anchor rod disc aligning washer, the anchor rod nut and the like are urgently needed.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide an auxiliary anchor net pressing tray and an anchor net pressing method, which meet the quality standardization regulations, flatten and thin the anchor net on the overlapped layer of the overlapping part of the anchor net to increase the exposed length of the end part screw thread of an anchor rod, and conveniently and quickly install components such as an anchor rod disc, an aligning gasket, an anchor rod nut and the like.
The purpose of the invention is realized as follows: the utility model provides an auxiliary anchor net pressing tray, including left half nut, the right half nut that links up mutually with the screw thread of left half nut, left half nut and right half nut are installed respectively and are fixed on left tray and right tray, left tray and right tray splice guarantee that left half nut and right half nut constitute a complete nut after being in the same place, the common suit in tray torsion shaft and can open and merge around the tray torsion shaft in one side of left tray and right tray, the opposite side of left tray and right tray is installed respectively and is fixed with taut knot pull rod and taut knot couple, left tray and right tray are in the same place through taut knot pull rod and taut knot couple locking.
The end part of the anchor rod with threads is arranged in a nut formed by the left half nut and the right half nut after the left tray and the right tray are spliced together, and the threads at the end part of the anchor rod are tightly matched with the internal threads of the left half nut and the right half nut.
Adopt box spanner or open spanner to block after fastening in place on the profile of left half nut and right half nut, supplementary anchor net tray that presses compresses tightly, flattens and overlaps multilayer anchor net, exposes the length increase back at the screw thread of stock tip, installs stock dish, aligning packing ring, stock nut at the stock tip.
A method for pressing an anchor net by using the auxiliary anchor net pressing tray comprises the following specific steps:
step 1, firstly installing an anchor rod before lapping, installing the inner section of the anchor rod in an anchor rod drilling hole, filling resin anchoring agent in the anchor rod drilling hole, arranging an anchor rod exposed section which protrudes out of the profile of a roadway outside the anchor rod drilling hole when the anchor rod is installed, and arranging threads at the end part of the anchor rod on the anchor rod exposed section;
step 2, laying anchor nets on the exposed sections of the anchor rods, wherein the exposed sections of the anchor rods must penetrate through the lap joints of the anchor nets;
and 6, after the auxiliary anchor pressing net tray is detached from the threads at the end part of the anchor rod, the anchor rod nut is screwed, so that the installation of each member of the anchor rod is completed, and the exposed length of the threads at the end part of the anchor rod meets the quality standardization regulation.
In the step 5, the bolt nut is kept in tight fit with the thread at the end of the bolt by 3-5 mm.
In the step 5, the anchor rod disc and the auxiliary anchor pressing net tray are kept at a certain distance, so that the auxiliary anchor pressing net tray is convenient to disassemble.
The invention has the following positive effects: the quality standardization stipulates that anchor rods must penetrate through the overlapping part of the anchor net. The number of overlapped layers at the lap joint of the anchor nets is large, so that the threads at the end part of the anchor rod are blocked, and the threads at the end part of the anchor rod are exposed to be short. The bolt end part thread is exposed to be short, so that the components such as a bolt disc, an aligning gasket, a bolt nut and the like are inconvenient to install. When the number of overlapped layers at the overlapping part of the anchor nets is large, and the threads at the end parts of the anchor rods are exposed to be short, the auxiliary anchor net pressing tray can be used for flattening and thinning the anchor nets at the overlapped layers at the overlapping part of the anchor nets, the exposed length of the threads at the end parts of the anchor rods is increased, and then the anchor rod discs, the aligning gaskets, the anchor rod nuts and other components are installed, so that convenience and rapidness are realized, the completeness of the anchor rod components can be ensured, and the quality standardization regulations are met.
