M50 harsh non-shrinkage mortar construction method

Harsh non-shrinkage mortar M50 harsh non-shrinkage mortar construction method 1, prefabricated T beam before, first install the bearing at the bottom of the T beam, tighten the bearing plate on the bolt, the bearing plate and beam bottom shall not leave gaps between embedded steel plate, if there are any gaps, grouting methods should be taken to be populated, leveling, bearing should carefully when factory assembly of upper and lower bearing plate, with a connecting plate bearing connected into a whole. 2, table surface treatment: on the surface of the bearing pad stone that need to grouting to remove dust, grease and other dirt does not favor the bonding material, base application water wet to saturation, but construction, MingShui should not be maintained. Before 3, T beam beam at the top of the bearing pad stone spread a layer of 20 ~ 30 mm thick high-strength mortar harsh non-shrinkage mortar, mortar top spread into the shape of a around slightly above middle, anchor bolt hole is also dao with corresponding Gao Qianggan hard non-shrinkage mortar. Sprinkler maintenance Gao Qianggan rigid non-shrinkage mortar in a timely manner. 4, M50 harsh non-shrinkage mortar materials by powder: water = 1-0. 12 ~ 0. 15 ( Weight ratio) Preparation. Should be first to add water to mixing barrel, then gradually add weighing good powder, while feeding, rob to stir with electric mixer, until the powder is added, and continue to stir 2 ~ 3 minutes, make the paste evenly. 5, multi-plate T beam, when installation should be lifting the middle two pieces T beam, and after the two pieces of T beam hoisting in place, timely welding two pieces of the T beam, the connection between the steel and symmetric lifting the rest of the T beam, after every piece of T beam in place, set up the temporary support, timely corresponding connection steel welding. Between June and T beam in laminated diaphragm plate after concrete pouring and achieve strength, dismantled pedestal connector plates and bolts, the installation pedestal coaming, each bearing are in normal working condition.
