Installation Technology Details
1. before pouring concrete in the next section, has emerged the vertical (horizontal) or transverse to the (Central) to the construction joints shall be installed with water to the interface.
2 .how to fix water to take the lead board, they have under the framework of the construction methods and machinery equipment capacity to identify, can be nails, bolts or wire fixation. In short its fixation by the construction workers to fully exercise its imagination, to set aside groove convenient, fast, materials and purposes. 3. a fixed water to be pasted in the construction joint, the latter poured joint interface should be kept dry, flat seam construction to eliminate the interface before the scum, dust and debris.
4, water to install the site is confirmed, the need to install the water to the interface and water to the bottom are coated with a thin layer of adhesive, to be volatile for some time before glue paste, or high strength screw water to a fixed position in the established installed.
5. In case of wet or uneven concrete interface, fixed on the adhesive paste is not strong, the visual condition with high-strength concrete nails to further enhance fixation. Short water to be in close contact with the concrete interface, fixed rate real, to prevent loss of water to seepage from the interface and the role.
6, with water to make the water to locate installed by pouring concrete package, package thickness> 50mm.
7, with water to extend the use of joints used to connect overlapping methods lap, lapping paste and then use high-strength outer nail fixed, the installation path along the construction joint form a closed loop, during which breakpoints can not stay.
8, water to locate the next one after the pouring of concrete, should avoid being soaked in rain and other water immersion.
9, pouring concrete vibrators should be touched with water to avoid vibration rods.
10, with water to storage and transport, avoid moisture and compressive deformation.
