Introduction by doing anchor bolt tension meter construction drawing preparation before the test 1. Material (1) prestressing strand rod material should be selected, high-strength steel or high-strength rebar. When the value is smaller or prestressed bolt length is less than 20m, the tendons may also be Class II or Class III reinforced. (2) cement paste material: cement should be ordinary portland cement, sulphate resisting cement can be used, if necessary, may not use high alumina cement. Fine aggregate should be used in sand particle size less than 2mm. Using water meets the requirements, the use of sewage shall not use acidic PH value of less than 4 water. (3) a plastic material casing: should have sufficient strength to ensure it will not be damaged during the installation process, and having water resistance and chemical stability, and preservative in contact with cement mortar without adverse reactions. (4) the spacer frame by steel, plastic or other material rod harmless, may not use wooden spacer frame. (5) anti-corrosion materials: in the service life of the Qinghai anchor bolt tension meter, should maintain its durability within the specified operating temperature or tensioning process does not crack or become brittle fluid Gansu bolt tension meter, shall not be adverse reactions to the adjacent material should retain its chemical stability and water resistance, deformation of the bolt can not be free of any restriction section. Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City produced according to the tension bolt tension meter detection range is divided into: 5 tons of bolt tension meter, 10 tons of bolt tension meter, 20 tons of bolt tension meter, 30 tons of bolt tension meter, according to the display different ways and accuracy are divided into two types of mechanical and digital explicit. Now understand the principles supporting bolt, then let us introduce installation works under the bolt. ① check bolt installation: install anchor bolt tension meter in front of Shaanxi, 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, then the placement of coal drill or blender, start mixing, stirring anchor time of 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. Required bolt tension meter pallet close to the wall, two single pad and tighten the cap, non-padded pallet anti-A or coal blocks. Finally, with a torque wrench to tighten the nut double that of prestressed anchoring force of up to 90%. 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.
