Pre-buried construction method for high-precision foundation bolts

Abstract

The invention discloses a pre-buried construction method for high-precision foundation bolts. The method includes the following steps that (a), construction preparation is performed; (b), a control net is established; (c), a positioning clamp and a positioning control plate are manufactured; (d), foundation steel bars are buried in advance; (e), the positioning clamp is installed; (f), the foundation bolts are installed; (g), the foundation bolts are reinforced and protected; (h), concrete pouring is performed; (i), the clamp is dismantled; (j) acceptance inspection and handover are performed to finish the pre-buried construction. The manufactured high-precision positioning clamp is adopted for performing clustering control over the pre-buried foundation bolts of each set of equipment foundations, elastic clamping tools are arranged on the outer sides of the foundation bolts, supporting legs of the elastic clamping tools are embedded into clamping holes in the positioning clamp, and the elastic clamping tools are clamped on the positioning clamp of the foundation bolts, so that the foundation bolts are further reinforced and prevented from loosening. The pre-buried construction method has the effects of being reliable in technology, high in construction precision, easy to understand and master and convenient to operate, and meanwhile is short in construction period and low in cost.

Description

technical field [0001] The invention belongs to the field of steel structure construction engineering, and in particular relates to a high-precision foundation bolt pre-embedded construction method. Background technique [0002] With the continuous development of the market economy and the increasing improvement of the construction market, steel structure engineering is also more and more favored by construction units. It is not difficult to see from the inspection of the actual construction process of the steel structure that the accuracy of the pre-embedded anchor bolts of the steel structure foundation It is a very important factor affecting the quality of steel structure installation. At present, the installation of power transmission substations, nuclear power plants, and various large-scale new industrial equipment, including steel structure workshops, is increasing, and pre-embedded anchor bolts for various foundations (especially equipment foundations) are widely use...

AI Technical Summary

Problems solved by technology

At present, the installation of power transmission substations, nuclear power plants, and various large-scale new industrial equipment, including steel structure workshops, is increasing, and pre-embedded anchor bolts for various foundations (especially equipment foundations) are widely used. Compared with traditional buildings, this type of The pre-embedded bolts of the foundation of the building have many specifications, large quantities, and high construction accuracy requirements. Once a large deviation occurs in the pre-embedded individual bolts, it will directly affect the normal installation and commissioning of various equipment. , There is a gap between the positioning fixture and the anchor bolts, which is easy to cause loosening, resulting in low embedded precision, affecting the normal installation and debugging of the equipment, and causing quality accidents
