Installation method of complicated group anchors

Abstract

The invention provides an installation method of complicated group anchors, which is used for fixing anchor plates to the surface of a substrate material. The method comprises the following steps: step A, leveling a base layer to make the surface smoothness deviation to be less than or equal to + / -1mm; step B, determining drawing positions of a plurality of anchor bolts on the surface of the substrate material according to a design drawing; step C, probing steel bars in the drawing position of each anchor bolt to determine the actual position of the anchor bolt; step D, drilling holes in the actual positions of each anchor bolt on the substrate material, controlling the hole drilling depth with the depth deviation between 0 and 2 mm, and placing the anchor bolts into the holes; step E, pasting PVC plates with the same size as the anchor plates to the anchor bolts, and marking the position of the center point of each anchor bolt on the surface of each PVC plate; step F, drilling holes on the anchor plates according to the actual position distribution maps of the anchor bolts on transfer plates; and step G, installing the anchor bolts, then, pasting the anchor plates to the surface of the substrate material so the end of each anchor bolt passes through the corresponding hole formed on the anchor plates, and installing screw nuts of each anchor bolt.

Description

technical field [0001] The invention relates to building anchor bolts, in particular to a method for installing complex group anchors. Background technique [0002] The research, production and application of anchor bolts have a history of more than 50 years. With the development of infrastructure construction and the upgrading of building interior and exterior decoration, various building curtain wall installations, nuclear power plant establishments, subways, urban railways and other constructions, It has effectively promoted the rapid development of anchor bolt fastening technology. [0003] In the building structure, anchor bolts are gradually replacing embedded parts in many aspects due to their anchoring reliability and installation flexibility. It is widely used in door and window installation, road guardrail, pipe support, architectural decoration, building renovation, reinforcement and other projects, and has become a widely used and promising product.

AI Technical Summary

Problems solved by technology

Obviously, the current installation method of anchor bolts cannot meet the installation accuracy requirements of self-cutting bottom anchor bolts.

In addition, when the actual position distribution map of the anchor bolts rubbed on the wooden board is transferred to the anchor board, there will be a large error again. Therefore, the installation accuracy of the group anchor installation method currently used cannot meet the requirements of self-cutting bottom anchor bolts. Installation Accuracy Requirements

When the installation accuracy does not meet the requirements, the anchor bolt may slip or even break away from the installation hole, which will affect the quality of the building
