Adjustable locating device for steel structural support

Abstract

The invention belongs to the field of civil engineering and relates to an adjustable locating device for a steel structural support joint supported onto a concrete structure. The adjustable locating device comprises a locating device and an adjusting device, wherein the locating device comprises a support, an anchoring plate and an adjusting ring plate; the support, the anchoring plate and the adjusting ring plate are formed into a whole in the manner of welding; the anchoring plate is evenly provided with mounting holes along the centerline; and anchor bolts or anchor bars pass through the mounting holes, and then, are welded all around at the positions on the anchor bolts or anchor bars, which are contacted with the anchoring plate. The adjusting device comprises adjusting anchor bolts, adjusting nuts, gaskets, adjusting holes and the adjusting ring plate, wherein the adjusting anchor bolts are connected with the concrete structure; and the adjusting anchor bolts respectively pass through mounting holes at the centers of the gaskets and are fixed with the gaskets through screwing down the adjusting nuts and the adjusting anchor bolts. The locating device can be used for performing multidirectional adjustable location, and thereby, the installation accuracy can be conveniently controlled. The adjustable locating device is wide in applicability and simple in construction operation, can meet the safety requirements on connection in joint areas, and is arranged in a concrete member to double as a support.

Description

[0001] technical field

[0002] The invention relates to the field of civil engineering, in particular to an adjustable positioning device for a steel structure bearing node supported on a concrete structure.

[0003] Background technique

[0004] In recent decades, the application of steel structure has become more and more extensive, and the lower supporting structure of steel structure engineering usually adopts concrete structure. At present, the design and construction of steel structure support joints have been deeply and extensively studied, and the relevant methods and specifications are becoming more and more mature. Steel structure support nodes are the most critical parts in structural engineering. The accuracy of construction positioning and the reliability of supporting structure connections directly affect the smooth installation and safety of the project. However, due to the limitation of construction methods and construction accuracy, it is particularly dif...

Examples

Embodiment Construction

[0033] Such as Figure 1 ~ Figure 2 As shown, the anchor plate 2, the bracket 3 and the adjusting ring plate 4 are connected by welding to form an overall positioning device. The anchor plate 2 is evenly provided with installation holes along the center line. The diameter of the installation hole is 1-2 mm larger than the diameter of the anchor bolt or anchor bar 1. The anchor bolt or anchor bar 1 passes through the installation hole, and the contact position with the anchor plate 2 is connected by surrounding welding. The width of the anchor plate 2 is taken as 3d1, where d1 is the diameter of the anchor bolt or the anchor bar 1. The width of the adjusting ring plate 4 is the larger value between 150mm and 3d1, and the grouting holes 8 are evenly arranged on the adjusting ring plate 4, and the diameter of the grouting holes 8 is 50mm. The anchor plate 2 is positioned within the length range of the anchor bolt or anchor bar 1; the lower end of the anchor bolt or anchor bar 1 ...
