Description
Technical field
The invention belongs to steel building field, more particularly to a kind of means to save the situation of steel column foot crab-bolt dislocation.
Background technology
With the fast development of China's assembled architecture, steel structural form is more and more applied to industrial building and civilian
Building.Steel column foot is attached fixation, but the embedding often dislocation of live crab-bolt using crab-bolt more, causes steel column not install.
Traditional treatment method is：Former crab-bolt is cut off, and redrilling bar planting, carries out live pull-out test.Due to reinforcement foundation and former crab-bolt
Presence, cause drilling, borehole cleaning trouble, rebar-planting quality tends not to ensure, it is difficult to reach the requirement of design bearing capacity, so this
The use of kind suspension column rectification mode is limited by increasing.
The content of the invention
In order to solve problems of the prior art, it is an object of the invention to provide one kind can be easy to construction, and can
Ensure the means to save the situation of the steel column foot crab-bolt dislocation of construction quality.
In order to realize foregoing invention purpose, the present invention uses technical scheme as described below：
A kind of means to save the situation of steel column foot crab-bolt dislocation, including steel column and concrete foundation, the side of being welded with the suspension column of steel column
The heel slab of shape, the edge on heel slab are provided with some suspension column preformed holes, are provided with concrete foundation and institute
The crab-bolt of the identical quantity of suspension column preformed hole is stated, all crab-bolts are dislocation with all suspension column preformed holes, wherein, the anchor in left side
Bolt A corresponds to inside steel column, and the crab-bolt B on right side is located at outside steel column, and crab-bolt C and the suspension column on heel slab of upper and lower side are reserved
Hole sequence；Described means to save the situation specifically includes following steps：
1. setting a square anchor slab in the crab-bolt in concrete foundation, the area of anchor slab is more than the area of heel slab, in anchor
The through hole passed through for all crab-bolt A, crab-bolt B and crab-bolt C is opened up on plate, the crab-bolt A in left side, the crab-bolt B on right side are passed through on anchor slab
Corresponding through hole, and part crab-bolt A and crab-bolt B ultrasound gone out after anchor slab is cut off, the crab-bolt C of upper and lower sides is corresponding through anchor slab
On through hole；
2. the heel slab is correspondingly arranged on anchor slab, the suspension column hole corresponding with crab-bolt C is opened up on heel slab, upper and lower sides
Passed through after crab-bolt C is corresponded to through the through hole on anchor slab and out of suspension column hole, crab-bolt C installs pad after passing through suspension column hole on crab-bolt C
Piece and clamp nut, two clamp nuts are set on each crab-bolt C；
3. plug welding is carried out with heel slab to anchor slab to connect, so that anchor slab and heel slab are fastenedly connected and are integrated, and anchor slab and post
The plug welding of sole connects in two kinds of situation, is specially：
A, when suspension column plate thickness is not more than 20mm, the suspension column preformed hole of dislocation corresponding with crab-bolt A, crab-bolt B on heel slab is entered
Suspension column is simultaneously reserved eyelet welding and expired by row plug welding；
B, when suspension column plate thickness is more than 20mm, the suspension column preformed hole of dislocation corresponding with crab-bolt A, crab-bolt B on heel slab is carried out
Open 300Slope is spread, to ensure welding quality；
4. carrying out plug welding to crab-bolt A, crab-bolt B and anchor slab to connect, through hole corresponding with crab-bolt A, crab-bolt B on anchor slab is expanded
Slope, crab-bolt A, crab-bolt B upper ends are located in the through hole of ramped shaped and carry out plug welding to through hole, through hole welded full；
5. the pad and heel slab are carried out into weld all around, heel slab surrounding and anchor slab are subjected to weld all around at the scene；
6. surface at crab-bolt position in concrete foundation is carried out into dabbing processing, make to be formed after concrete surface dabbing recessed
Fall into, during dabbing, the reinforcing bar in concrete foundation must not be injured, pressure grouting then will be carried out in described depression, fill
Slurry is CGM high-strength grouts, and anchor slab bottom is realized into high intensity is connected with concrete foundation.
Preferably, the thickness of the anchor slab is 40mm.
Preferably, the material of grouting is CGM high-strength grouts.
Due to there is following superiority using above-mentioned technical proposal, the present invention：
The present invention fully can use the crab-bolt of dislocation, weaken very little to steel column foot bearing capacity, avoid and bore again
Hole, borehole cleaning, the trouble of bar planting, and which weaken very little to steel column foot bearing capacity, not only economic but also safety.
