Abstract
The invention relates to a steel frame reinforced column and a reinforcing method thereof. The steel frame reinforced column is characterized in that sealing reinforcing steel plates are welded between two flanges at two sides of an H-shaped steel frame column along the overall length of the column, are arranged in pair at two side openings of the H-shaped steel frame column and are welded with two flanges at the opening of the H-shaped steel frame column, and two sealing reinforcing steel plates adjacent up and down are mutually welded. In the invention, the reinforcing steel plates are prefabricated into parts in advance, are directly hoisted to the position during construction, pass through the steel column in over length along the direction of a weak shaft of the H-shaped steel frame column and are welded in pair, thereby enabling the structure stress of the steel reinforced column to be more reasonable and the structural bearing of an original building to be enlarged and satisfying the structural bearing stress requirement. By adopting the construction method of the invention, the original structure can be used for reinforcing the frame steel column of the original steel structure without being disassembled, thereby not influencing the normal work in the original building. All the reinforcing steel plates can be precast in factories, thereby not only shortening the time limit for a project and reducing the construction cost but also ensuring project quality and satisfying the requirement of building extension.
Description
Technical field
The present invention relates to a kind of ruggedized construction and reinforced construction method of construction steel frame post.
Background technology
Along with the fast development of large-span space structure building, the designed structural span of architect is also increasing, and moulding is more and more novel, unique, and structure connects and becomes increasingly complex.Original steel structure member is because historical reasons and the passing of time cause local damage, corrosion easily, or because member section is little, bearing capacity is low, can't satisfy the requirement of workmanship.Existing reinforcing mode can't be in the existing building normal office work, and under the situation about not unloading the original structure Steel Frame Column is transformed, reinforced.Existing structural strengthening mode complex procedures, circulation material have high input, long construction period, can not adapt to the requirement of modern architecture construction.
Summary of the invention
The purpose of this invention is to provide a kind of steel frame reinforced column and reinforcement means thereof, solve existing steel work reinforcement means and need unload construction, working procedure complexity, long technical problem of cycle.

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.
Step 2 is set up non-bearing operation scaffold around being reinforced H structural steel frame post.
Step 3 puts prefabricated strengthening steel slab lifting in place.
Step 4 is reinforced H structural steel frame post suspension column, and concrete steps are as follows: A, web of each vertical welding is reinforced the strength plate on the web two sides of H structural steel frame post, and web is reinforced the strength plate weld with the steel column base plate.
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.
Step 5, reinforce H structural steel frame post typical construction, weak direction of principal axis at H structural steel frame post seals strengthening steel slab along the welding of steel column total length, organizes the right strengthening steel slab that seals and is symmetrically welded in the both sides open-mouth of H structural steel frame post, and the neighbouring strengthening steel slab that seals is welded to each other.
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.
