Abstract
The invention discloses a construction method for a steel column base and a steel column base structure thereof. A transition plate is welded on an anchor bolt by using a plug welding method; then a bottom plate of a steel column is welded on the transition plate by using triangular welding; and the original threaded connection is changed into welding connection. By adopting the method, the mounting is facilitated; and waste in materials and labor time caused because a concrete foundation is required to be knocked down to newly construct in the case of deviation in the position of the anchor bolt of the steel column base in the prior art is avoided. The steel column base has a simple structure, is low in construction cost and can guarantee safety and reliability during mounting.
Description
Technical field
The present invention relates to a kind of job practices and steel column leg structure thereof of steel column pin, belong 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 objective of the invention is to, 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 job practices and the steel column leg structure thereof of the steel column pin of the safety that can guarantee to install and reliability, thereby overcome the deficiencies in the prior art.
Technical scheme of the present invention: the job practices of a kind of steel column pin of the present invention is, by following step construction,
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.
The steel column leg structure of the present invention that makes up by the job practices of above-mentioned steel column pin is: 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 present invention adopts 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 invention 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 invention simple in structure, operating expenses is low, and can guarantee the safety and the reliability of installing.

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 present invention is described in further detail below in conjunction with drawings and Examples.
Embodiment.Structure of the present invention 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.
By the steel column leg structure of the present invention that the job practices of above-mentioned steel column pin makes up, comprise basis 1, during making, in basis 1, be embedded with one group of crab-bolt 2, be 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.
