Description

Positioner of independent basis embedded column base crab-bolt

Technical Field

The utility model relates to a steel construction installation engineering particularly, relates to a positioner and construction method of independent basis embedded column base crab-bolt.

Background

The steel structure has the advantages of high strength, light dead weight, excellent earthquake resistance, simple and rapid construction, high installation accuracy and the like, is widely applied to modern large-span building engineering such as large-scale industrial plants, bridges, venues, super high-rise buildings and the like, and is the development trend of the existing assembly type structure. In the design and construction of a steel structure, the anchoring mode of a foundation and a steel column conventionally adopts an exposed column base structure and an inserted column base structure, the exposed column base is an embedded column base anchor bolt in an independent foundation, and the steel column is connected with the foundation by the anchor bolt.

Because the installation of a steel structure has strict quality requirements, the embedding precision of the column base anchor bolt directly relates to the position deviation of the integral verticality, plane bending and the like of a steel column and an upper structure, and is a vital control technology in the installation and construction of the steel structure, and the allowable deviation of the position of the column base anchor bolt is specified in the acceptance and acceptance criteria of the construction quality of steel structure engineering (GB 50205-2001).

Because the height of the independent foundation short columns is different, the embedded anchor bolts are suspended on the upper part of the foundation, the positioning and the reinforcement of the anchor bolts have great difficulty, and in the prior art, the installation and the fixation of the independent foundation column base anchor bolts usually adopt the following three methods:

the fixed bracket method: welding angle steel and reinforcing steel bars to form an anchor bolt fixing bracket, wherein the angle steel is provided with holes according to the diameter and the distance of the anchor bolt and is used as a limiting plate of the anchor bolt; utilize reinforcing bar preparation vertical braces and fixed bolster welding to erect in the basic unit, weld horizontal reinforcing bar and be connected anchor bolt and foundation reinforcement fixedly. The auxiliary materials used in the construction method of the positioning embedded anchor bolt are all disposable, cannot be recycled, have large material loss amount, are complex to manufacture and have high construction cost; the welding workload is large in the manufacturing and reinforcing processes, and the anchor bolt is very difficult to adjust if deviation exists after being fixed; in the design requirements, the anchor bolt and the reinforcing steel bar are not allowed to be welded, stress concentration is generated after the anchor bolt is welded, the design performance of the anchor bolt cannot be achieved, and the safety of the main body structure is influenced; the perpendicularity control of the anchor bolt depends on manual measurement, the pre-buried precision is difficult to ensure, displacement is easy to generate under the impact load of concrete pouring, and the installation of a main body structure is directly influenced.

Positioning a sleeve plate method: adopt 6mm thick steel sheet preparation crab-bolt location lagging, the lagging is according to crab-bolt diameter and interval trompil, and the upper portion is fixed with the nut after emboliaing the crab-bolt, and the lower part utilizes short reinforcement welding to be the frame, and short reinforcement and side form top are tight, and the welding transverse reinforcement is connected crab-bolt and foundation reinforcement, makes crab-bolt and steel reinforcement cage fuse and prop up tightly with the template and consolidate. The construction method of the positioning embedded anchor bolt needs to consume a large amount of auxiliary steel bars and steel plates, is complex to manufacture, has large material loss and welding amount, and has higher cost; the group of positioning sleeve plates can only be suitable for positioning the anchor bolts with one specification and size, cannot be flexibly adjusted according to actual needs, are disposable and have poor universality; the anchor bolts, the foundation steel bars and the side molds are all fixed into a whole, and the anchor bolts move all at once under the action of concrete pouring load, so that the deviation of the anchor bolts is easily caused, and the verticality of the anchor bolts is difficult to effectively ensure; the service performance and the structural safety of the anchor bolt are affected after welding.

Frame welding method: utilize the reinforcing bar of phi 16 above to weld the embedded anchor in every independent basis as whole frame, the rigidity support is established with adding to the four sides, and whole frame is connected to one end, and the other end supports on basic unit's bottom plate, waits that basic reinforcement finishes, welds whole frame and basic reinforcement as an organic whole again. The construction method for positioning the embedded anchor bolt not only consumes a large amount of auxiliary steel bars, but also has complex construction procedures, large welding workload, time and labor waste in carrying, installing and reinforcing the whole framework, long construction period, high labor intensity of workers and low working efficiency; after the fixing, the anchor bolt is not easy to adjust, and the anchor bolt is easy to deviate in the concrete pouring process; the potential safety hazard that the service performance of the anchor bolt is reduced after welding also exists.

An effective solution to the problems in the related art has not been proposed yet.
