Construction method of equipment foundation anchor bolt preformed hole and application structure of equipment foundation anchor bolt preformed hole

Abstract

The invention discloses a construction method of an equipment foundation anchor bolt preformed hole and an application structure of the equipment foundation anchor bolt preformed hole and relates to the technical field of petrochemical engineering construction. The construction method comprises the preparation procedure of threaded rods and a threaded rod fixing frame and the construction procedure for applying the threaded rods. The construction procedure for applying the threaded rods comprises the steps of arranging the threaded rods, fixing the threaded rods, adjusting the embedding depthof the threaded rods, checking the threaded rods, wetting the surfaces of the threaded rods, pouring concrete of the equipment foundation, taking out the threaded rods and clearing the anchor bolt preformed holes. By the adoption of the technical scheme, the anchor bolt preformed holes of the equipment foundation are constructed through the threaded rods, so that the technical defects that by theadoption of a temporary wood formwork supporting method, installation is inconvenient, the detachment destructiveness is large, and the formation quality is poor are overcome; the construction methodwith the threaded rods is simple and rapid, the material selection range is wide, the materials are easy to obtain, the construction method is safe and reliable in construction application, and the formation quality is good; and the threaded rods can be repeatedly used after construction is performed once, so that cost is saved.

Description

technical field [0001] The invention relates to the technical field of petrochemical engineering construction, in particular to a construction method and an application structure for reserved holes for anchor bolts of equipment foundations. Background technique [0002] In the construction of petrochemical engineering projects, a large number of equipment foundations (civil works) need to be constructed. Generally, it is necessary to reserve equipment anchor bolt holes during concrete foundation construction. The traditional construction method is: use wooden templates on site to make molds for the holes reserved for anchor bolts, pre-bury them before pouring concrete, and break them out after the concrete solidifies. [0003] However, in the process of implementing the embodiments of the present invention, the inventors of the present application found that the traditional construction method has at least the following technical problems: ① There are many reserved holes for...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned technical problems, the purpose of the present invention is to provide a construction method for the reserved holes of the foundation bolts of the equipment foundation. The formwork support method has technical defects such as inconvenient installation, high demolition destructiveness, and poor molding quality. The construction method using threaded rods is simple and quick, with a wide range of materials and easy access. It is safe and reliable in construction applications, and the molding quality is good. After the second grouting The effect is better, and the threaded rod after one construction can be reused, saving cost
