Auxiliary anchor net pressing tray and anchor net pressing method

Abstract

The invention relates to an auxiliary anchor net pressing tray capable of flattening anchor nets at the overlapped joints and facilitating the installation of anchor rods, aligning washers, anchor rodnuts and other components and an anchor net pressing method. The auxiliary anchor net pressing tray includes a left half nut and a right half nut connected with the thread of the left half nut; the left half nut and the right half nut are separately fixed on a left tray and a right tray; the left tray and the right tray are spliced together to ensure that the left half nut and the right half nutform a complete nut; one side of the left tray and the right tray are sleeved together on a tray torsion shaft and can be opened and combined around the tray torsion shaft; the other side of the lefttray and the right tray are separately installed with a tension buckle pull rod and a tension buckle hook; and the left tray and the right tray are locked together by the tension buckle pull rod and the tension buckle hook. By using the invention, after the overlapped anchor nets at the overlapped location is flattened and thinned, the exposed length of the thread at the end of the anchor rod is increased, which is convenient and fast, can ensure that the anchor rod components are complete, and meet quality standardization regulations.

Description

technical field [0001] The invention relates to an auxiliary anchor net pressing tray and an anchor net pressing method capable of flattening anchor nets at overlapping joints and conveniently installing components such as anchor rods, self-aligning washers and anchor nuts. Background technique [0002] There are regulations on the exposed length of the thread at the end of the anchor rod. If it is too long, it does not meet the quality standards, and if it is too short, it is inconvenient to install the anchor rod member. There are 2 to 8 overlapping layers at the overlap of anchor and net, and the thickness is also 30 to 80 mm. The thread at the end of the anchor rod at the overlap of anchor and net is blocked by the anchor net, resulting in a small exposed length of the thread at the end of the anchor rod, which is inconvenient to install the anchor rod Discs, self-aligning washers, anchor nuts and other components, even if forced to install and construct, it is time-cons...

Problems solved by technology

[0002] There are regulations on the exposed length of the thread at the end of the anchor rod. If it is too long, it does not meet the quality standards. If it is too short, it is inconvenient to install the anchor rod member.

There are 2 to 8 overlapping layers at the overlap of anchor and net, and the thickness is also 30 to 80 mm. The thread at the end of the anchor rod at the overlap of anchor and net is blocked by the anchor net, resulting in a small exposed length of the thread at the end of the anchor rod, which is inconvenient to install the anchor rod Plates, self-aligning washers, anchor nuts and other components, even if forced to install and construct, it is time-consuming and laborious

In this case, in order to facilitate the installation of the anchor nut, the construction personnel threw away the self-aligning washer of the anchor rod, and directly installed the anchor nut, resulting in incomplete anchor rod components and unqualified engineering quality.
