The described strengthening steel slab that seals is slotted in the intersection with steel-frame beam, and steel-frame beam embeds in the above-mentioned groove.
The welding of strengthening steel slab base and steel column base plate is sealed at the suspension column place of described H structural steel frame post, and each vertical welding of web two sides of H structural steel frame post is connected to a web and reinforces the strength plate, and web is reinforced the base and the welding of steel column base plate of strength plate; Seal strengthening steel slab and reinforce the welding of strength plate with web simultaneously, each vertical welding of two wing plates middle part of H structural steel frame post is connected to a wing plate and reinforces the strength plate, and wing plate is reinforced the base and the welding of steel column base plate of strength plate.
The variable cross-section place of described H structural steel frame post also is welded with one deck steel liner plate sealing between strengthening steel slab and the H structural steel frame post.
The described weld seam that seals between strengthening steel slab and the steel column base plate is butt weld; The weld seam that web is reinforced between strength plate, wing plate reinforcing strength plate and the steel column base plate is a penetration T type weld seam; The weld seam that seals between strengthening steel slab, web reinforcing strength plate, wing plate reinforcing strength plate and the H structural steel frame post is the fillet weld seam.
The reinforced construction method of this steel frame reinforced column, construction sequence is as follows: step 1, the fireproof paint of H structural steel frame post is removed and cleaned out.
B, between two wing plates of H structural steel frame post both sides the solder up strengthening steel slab, and will seal strengthening steel slab and web and reinforce the welding of strength plate, will seal strengthening steel slab and steel column base plate and weld.
C, in the middle of two wing plates of H structural steel frame post, respectively weld a wing plate and reinforce the strength plate, and wing plate is reinforced the strength plate weld with the steel column base plate.
In H structural steel frame post and steel-frame beam intersection, will seal the web thickness fluting of strengthening steel slab in advance according to steel-frame beam, steel-frame beam is embedded in the above-mentioned groove, will seal the two wing plates welding of strengthening steel slab and H structural steel frame post open-mouth again.
The variable cross-section place of described H structural steel frame post also is welded with one deck steel liner plate sealing between strengthening steel slab and the H structural steel frame post.
When the typical construction of described H structural steel frame post was reinforced, the longitudinal angle weld seam between solder up strengthening steel slab and the H structural steel frame post was waited to be reduced to after the environment temperature in the neighbouring horizontal butt weld of sealing strengthening steel slab of welding earlier again.
Described web reinforces the strength plate, seal strengthening steel slab and wing plate is reinforced the strength plate when weld with H structural steel frame post, welds longitudinal weld longitudinal seam after all welding transverse weld earlier.
Beneficial effect of the present invention is as follows: the present invention is according to easy construction, rational principle, the strengthening steel slab that the steel framework reinforced column is used is prefabricated into part earlier, directly lift during construction and put in place, direction of principal axis connects the welding of steel column total length a little less than H structural steel frame post, can make the structure stress of steel reinforced column more reasonable, the structural bearing capacity of original building is strengthened, satisfy the structural bearing force request.Adopt job practices of the present invention, original structure need not to unload and can carry out strengthening construction to the framework steel column of former steel work, does not influence the normal office work of existing building.All strengthening steel slabs all can adopt prefabrication, not only can the reductions of erection time, reduce construction cost, and also guarantee workmanship, and can satisfy the needs of building enlarging.
