Abstract
The utility model discloses a steel column base structure, which includes a foundation, a group of anchor bolts (2) are pre-buried in the foundation (1), the upper ends of the anchor bolts (2) are welded with a transition plate (3), a secondary grouting layer (5) is arranged between the transition plate (3) and the foundation (1); the upper plane of the transition plate (3) is welded with a bottom plate (7) at the bottom of a steel column (6); and the upper ends of the anchor bolts (2) are connected with the transition plate (3) through a plug weld (4). The steel column base structure adopting the method is convenient to install. The material and work hour losses caused by that concrete foundation needs to be removed and reconstructed when the positions of the anchor bolts of the steel column base have deviation in the prior art. The steel column base structure has a simple structure and is low in construction cost, and can ensure the safety and reliability of the installation.
Description
Technical field
The utility model relates to a kind of steel column leg structure, belongs to construction engineering technical field.
Background technology
The job practices of steel column pin is in the construction work at present, and the anchor of pre-buried steel suspension column is fastened in concrete foundation, and the end that anchor is fastened is provided with screw thread.When steel column was installed, the base plate of steel column bottom was fixed on the anchor that exposes basic end face with nut and fixes, and does the back-grouting layer again between base plate bottom steel column and the basic end face then, so just can transmit the superstructure load.But in work progress, the steel column pin anchor that exposes the concrete foundation end face is fastened the position and through regular meeting deviation is taken place, and makes the base plate of steel column bottom that difficulty is installed and maybe can't install.Though steel column pin anchor is fastened the position zero deflection sometimes, when being installed, steel column, heavylier breaks the screw thread that steel column pin anchor is fixed through regular meeting because the steel column quality is big, and nut can't be tightened, safety and reliability that influence connects.
Summary of the invention
The purpose of this utility model is, provide a kind of and be convenient to install, simple in structure, operating expenses is low, and the situation that can avoid invar suspension column anchor to fasten needing the dismantling concrete basis to construct again when deviation appears in the position takes place and the safety that can guarantee to install and the steel column leg structure of reliability, thereby overcome the deficiencies in the prior art.
The utility model is to constitute like this: comprise the basis, be embedded with one group of crab-bolt in the basis, crab-bolt upper end and rebound welding are provided with the back-grouting layer between rebound and the basis; The base plate welding of the last plane of rebound and steel column bottom.
In the aforesaid structure, be connected through plug welding on the described crab-bolt with between the rebound.
In the aforesaid structure, last plane three fillet welding of described rebound are connected with the base plate of steel column bottom.
In the aforesaid structure, described back-grouting layer adds that the thickness of rebound equals design elevation.
Compared with prior art, the utility model is to adopt the mode of plug welding to weld a rebound on crab-bolt, and then adopts the base plate of steel column three fillet welding to be welded on the rebound, changes original being threaded to and is welded to connect.Method of the present utility model is convenient to install, and can avoid prior art invar suspension column anchor to fasten the position when deviation takes place, and needs the dismantling concrete basis to construct again, and of the present utility model simple in structure, operating expenses is low, and can guarantee the safety and the reliability of installing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Being labeled as in the accompanying drawing: 1-basis, 2-crab-bolt, 3-rebound, 4-plug welding, 5-back-grouting layer, 6-steel column, 7-base plate, 8-three fillet welding.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: structure of the present utility model as depicted in figs. 1 and 2.When carrying out the construction of steel column pin, construct by following step,
A, when basis casting pre-buried one group of crab-bolt in the basis, treat that concrete is fixed after, with the crab-bolt levelling, make crab-bolt expose the length unanimity on basis;
B, making rebound with holes, the position in hole is corresponding with the crab-bolt position, crab-bolt is penetrated 1/3-1/2 in the hole of rebound, and make rebound and basic top reserve the gap of back-grouting, with the rebound levelling, and the design elevation between plane and the basis top on the assurance rebound, then in the hole with rebound and crab-bolt plug welding, and the scolder of giving prominence to polished flat;
C, the back-grouting layer of between top, basis and rebound baseplane, casting;
D, treat that the back-grouting layer is fixed after, the base plate on the steel column is seated in plane on the rebound, on the base of steel column base plate steel column base plate and rebound are welded together.
During concrete the making, steel column leg structure of the present utility model comprises basis 1, during making, is embedded with one group of crab-bolt 2 in basis 1, is connected through plug welding 4 between crab-bolt 2 upper ends and the rebound 3; And between rebound 3 and basis 1, back-grouting layer 5 is set; The thickness that makes back-grouting layer 5 add rebound 3 equals design elevation; The last plane trigonometry weldering 8 of rebound 3 is connected with the base plate 7 of steel column 6 bottoms.
Claims (4)
1. a steel column leg structure comprises basis (1), it is characterized in that: be embedded with one group of crab-bolt (2) in basis (1), crab-bolt (2) upper end and rebound (3) welding are provided with back-grouting layer (5) between rebound (3) and the basis (1); Base plate (7) welding of the last plane of rebound (3) and steel column (6) bottom.
2. steel column leg structure according to claim 1 is characterized in that: be connected through plug welding (4) on the described crab-bolt (2) with between the rebound (3).
