Bolt tension meter _ Warner electromechanical _ Zibo bolt tension meter provided by Warner electromechanical. Bolt tension meter _ Warner electromechanical _ Jinan bolt tension meter is the principle Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City (www.tahnjd.com) 2013 upgrade been newly launched bolting: can be divided into focus (end) anchor and the total length of the former is to make the anchor bolt anchor by tightening the head and the other end portion of the fundus end inhibition by tension surrounding rock deformation and loose. Seam can be divided into wedge anchor, expansion shell anchor, resin bolt prestressed anchor. The latter is a rod with a hole through the wall of the cementing material, so that the entire length of the bolt in the rock bonded together to produce rock anchoring effect. Including mortar anchor, resin bolt. Its way into the mechanical anchoring anchor type (by friction from Anchorage) and bonded anchor (anchor role played by adhesion). Bolting principles: (1) strengthening arch (arch squeeze combination) by the action of the bolt so that the formation of a rock with a certain thickness to maintain their stability and preventing its external reinforcement of loose rock rock arch in order to maintain stable. (2) the role of the bear hanging off the soft rock or rock suspended in the deep rock solid stability, the bolt to bear the weight of these rock. (3) the role of the organization Liang rock layers form a whole Qingdao bolt tension meter, increase its carrying capacity by anchor role in the layered rock. On this basis, in order to prevent loose rocks and weathering can spray 5-20CM mortar or concrete is shotcrete support. Now understand the principles supporting bolt, then let us introduce installation works under the bolt. Bolt installation ① check: Before installing the bolt, to check the direction of drilling, position, angle, depth, anchoring agent, anchor meets the design requirements, if a failure, it can not be installed. ② anchor head Mixing: After eye bolt kick timely installation requires a minimum operated by two people. When installing anchors, the first connector is screwed onto the threaded bolt tail, with the other rod to the bottom of the hole will be anchoring agent pier real Zibo bolt tension meter, then the placement of coal drill or blender, begin stirring bolt tension meter, anchor stirring for 30 to 40 seconds. Stir resin to force uniform, not too much. When taking coal drill, lift up the rod, after removing temporarily with small pieces of wood or small stones placed in the wells choked rod to prevent the rod decline. ③ pallet install: After the resin solidified, and then remove the connector, immediately install pallet, gaskets, when install pallet, the pallet to be lifted by one person hold the anchor set into another person quickly put on pads, tighten the nut on the double, the higher the roadway when another person needs to withstand the pallet with a long bar to prevent fall injuries. Requires close pallet wall, double cap single pad tighten security or anti prohibited pallets padded coal blocks. Finally, with a torque wrench to tighten the nut Zaozhuang double bolt tension meter, so that 90% of prestressed anchoring force. Turn from the outside and inside, playing a note one, will support all the empty top finish. Bolt must be tightened with a torque wrench tight mechanical or ensure close pallet wall.
