A construction method for refined pre-embedded structure of steel structure anchor bolts

Abstract

The invention relates to a construction method for a refined pre-embedded structure of a steel structural foundation bolt shaping mould. The construction method is characterized by comprising the steps of firstly, assembling an adjustable assembled mould frame on a prefabrication site or a construction site; after finishing location of structural members of the assembled mould frame, dismounting a formwork at the bottom, and enabling a foundation bolt to penetrate an assembly limiting bolt hole and a foundation bolt hole of the assembled mould frame; then, connecting an anchor bolt with a lower locating plate, and respectively adjusting the horizontality of the lower locating plate and the verticality of the foundation bolt through a levelling nut and a transverse connecting rib; next, filling a gap between an upper locating plate and the lower locating plate with a pre-locating grouting body by virtue of a pre-locating grouting pipe; and after the pre-locating grouting body is initially solidified, dismounting a formwork at the top, and carrying out foundation concrete pouring in other areas. By using the construction method, not only can the in-site installation and location time of the foundation bolt be shortened, but also the accuracy degree for locating the foundation bolt can be increased, and affects of foundation concrete pouring to the spatial position of the foundation bolt can be avoided.

Description

Technical field [0001] The invention relates to a construction method for a steel structure anchor bolt embedded structure, in particular to a steel structure anchor bolt shaping mold refined embedded structure construction method that can effectively shorten the on-site construction time and improve the positioning accuracy of the anchor bolts, belonging to In the field of construction engineering, it is suitable for the construction of steel structure anchor bolts. Background technique [0002] In recent years, with the rapid development of urban construction, the application of steel structures has become more and more common. In steel structure construction, the installation quality and positioning accuracy of steel structure anchor bolts have a prominent impact on the safety and construction quality of steel structures. [0003] There is a combined multifunctional anchor bolt positioning template. The frame of the template is formed by connecting four telescopic rods in seque...

AI Technical Summary

Problems solved by technology

Although this construction method can prevent the loosening of the anchor bolts, it is difficult to adjust the spatial position of the anchor bolts, and the on-site construction workload is large, so it is difficult to effectively improve the positioning accuracy of the anchor bolts

[0005] To sum up, although the construction technology and structure of the existing steel structure anchor bolts have achieved good engineering benefits under suitable working conditions, there are still some deficiencies, which are mainly reflected in the unreasonable design of the anchor bolt positioning structure ,, low positioning accuracy of anchor bolts, insufficient overall connection strength of the structure, and difficulty in site construction and assembly of the structure, etc.
