Description
Technical field
The present invention relates to one kind building ruggedized construction and its construction method, and in particular to a kind of for reinforced concrete column
Ruggedized construction and its construction method.
Background technology
Aging or building due to construction material use the change of function, and reinforcement technique is got in many building structure
To be more widely applied.But as the post component of one of the intermediate portions in structure, connected due to its upper and lower side with beam slab, plus
Gu construction surface is narrower, therefore is also the difficult point in reinforcing engineering, many technologies and construction problem are not well solved yet, into
To restrict the major issue of the appropriate reinforcement protection of building structure.
Existing reinforcement technique can be divided into Enlargement of Section, displacement concrete strengthening method, outsourcing shaped steel method, affixing steel plate or
Pasting carbon fiber composite material material method and steel bushing method for strengthening etc..Wherein, Enlargement of Section and displacement concrete strengthening method need
The processing such as formwork supporting plate is carried out, outsourcing shaped steel method needs to weld or use structure glue, affixing steel plate, carbon fibre composite method etc.
It is also required to use structure glue, there is construction complexity, the low problem of economy.
And the steel sleeve method for strengthening for being used for reinforced steel concrete post has the advantages that some following protrusions：
1st, sidewise restraint on the one hand is applied to compression concrete using steel sleeve, makes concrete in pipe should in three dimension stress
Power state, delays the occurrence and development of concrete microcrack, and the supporting role of another aspect concrete can also strengthen steel pipe walls
Geometrical stability, so that pillar rigidity and deformability can be greatly enhanced on the whole, so as to greatly improve holding for pillar
Carry power and improve anti-seismic performance；
2nd, structure glue need not be used, template is also required for, speed of application can be improved；
3rd, steel pipe good processability, from heavy and light, convenient construction, consolidation effect is good.
But, complete steel pipe can not be packed into solid post to be added and wait to reinforce, it is necessary to cut steel pipe and pack into again by steel sleeve reinforcing
Post, and the connection method of steel pipe still suffers from many shortcomings in existing steel sleeve reinforced concrete column, such as：Directly along steel sleeve pipe shaft
The method of length direction welding, localized hyperthermia can cause the defects such as stress concentration and the deformation of member, and welding technique is to operation
The technology of person is had higher requirements, and appropriate welding environment is generally required during welding operation, and the method needs Site Welding, work
Amount is big, and construction quality cannot also be ensured.
