Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of equipment for construction engineering, and particularly relates to an auxiliary device for installing a prefabricated cement board. Background Art
[0002] With the elimination of backward production capacity and the transformation and upgrading of the construction industry, prefabricated buildings have gradually become the mainstream structural form of the construction industry. The columns and shear walls of the structure are designed to be prefabricated. The PC components are made in the factory and installed and poured on site. The upper and lower sections of the components are connected by sleeves and post-grouting. Post-grouting refers to grouting as a subsequent process in foundation treatment. Among them, when installing the upper and lower sections, the design requires a gap to be left. After the installation and positioning, the gap between the upper and lower sections is sealed with mortar.
[0003] When using the conventional installation method, steel pads are placed at the corresponding positions before the upper component is installed. After the steel pads are leveled with a level, the upper component is hoisted for installation, mortar sealing, and sleeve grouting. The steel pads cannot be removed from the gap. As part of the permanent structure, and after the steel pads are installed in the upper section, they cannot be adjusted. If there is a deviation in elevation, the upper component needs to be hoisted and the steel pads reinstalled. The construction efficiency is low, and the steel pads require continuous investment as permanent structures, which increases the construction cost. Utility Model Content
