Description
Technical field
It the utility model is related to building structure field, and in particular to a kind of structure reinforced to concrete column.
Background technology
In the last few years, strengthening reconstruction class engineering was quickly grown in China, and the means on structural strengthening are also rich and varied, but
Be due to reinforce object be existing building, different from new building, thus in implementation process is reinforced understand to much it is intractable
Problem.
Reinforcing to concrete column has great significance in protection against and mitigation of earthquake disasters and shake post processing.For example, China is practical
New patent CN206071092U discloses a kind of Strengthening by Steel-Packing structure of steel reinforced concrete frame column after shake, including four angles
Steel, four angle steel are bonded four seamed edges for being arranged on steel reinforced concrete frame post respectively, the top of two neighboring above-mentioned angle steel and
It is fixedly connected between middle part by the batten plate of multiple bar shapeds laterally set, and multiple batten plate intervals equidistantly distributed, it is adjacent
Connected between the bottom of two above-mentioned angle steel by the Interal fixation of strip.
Said structure is realized by the surrounding processing to concrete column and reinforced, in the process, it is necessary to intending reinforcing object
The structures of surrounding are removed, to provide construction space.But some structures often remove the huge funds of consuming, even
May seriously it delay the duration.Such as when intending reinforcing water tank periphery concrete column or elevator corner post, concrete column
Certain while the filling wall or structures at place can not be removed due to the limitation of a variety of causes, it is clear that said structure is at these
It can not be applied under closing.
In addition, in similar applications, due to the dismounting of relative other side structures, the eccentric compression of concrete column can be caused,
In the case where bias is indulged muscle configuration deficiency by village side tension, the reinforcing of concrete column how is realized, is to need what is solved to ask
Topic.
The content of the invention
Goal of the invention of the present utility model is to provide a kind of unilateral steel clad reinforcement concrete column, is improved by structure, realizes
To reinforcing when being difficult to the wall removed around eccentric loading column be present, to ensure the economy reinforced, and accelerate the duration.
To achieve the above object of the invention, the technical solution adopted in the utility model is：A kind of unilateral steel clad reinforcement concrete
Post, including concrete column, covered with steel plate on a side to be reinforced of the concrete column, the steel plate is through crab-bolt
Bar planting is fixedly connected with the concrete column, and epoxy resin potting compound is provided between steel plate and the concrete column surface
Layer；The steel plate both sides are provided with wing plate, and the wing plate is covered each by two sides adjacent with side to be reinforced on concrete column
A part, and fixed respectively with two sides through crab-bolt bar planting, epoxy resin be provided between wing plate and concrete column body side surface
Irrigate glue-line.
In above-mentioned technical proposal, the side affixing steel plate of muscle configuration deficiency is indulged in concrete column tension, steel plate passes through shearing resistance
Crab-bolt is installed along the bar planting of concrete column surface, after steel plate installation, injects asphalt mixtures modified by epoxy resin to the gap between steel plate and concrete
Fat potting compound, thus, integral by shear amchor bolt and the connection of epoxy resin potting compound between steel plate and concrete column, both are common
With stress is coordinated, the unilateral steel clad reinforcement of concrete column is realized.
In above-mentioned technical proposal, the width of the wing plate is no less than 100mm.The setting of wing plate can ensure steel plate and coagulation
The switching performance of earth pillar so that the globality of ruggedized construction is more preferable.
In above-mentioned technical proposal, between 4~20mm, the spacing of adjacent crab-bolt exists the thickness of the steel plate and the wing plate
Between 200~600mm.The spacing of crab-bolt has considerable influence to the shearing resistance adhesive property between steel plate and concrete column, above-mentioned to set
Put the effect that can ensure to reinforce.
Preferable technical scheme, the crab-bolt diameter is between 12~22mm.
With a diameter of d of crab-bolt, higher value of the bar planting depth not less than both 100mm and 10d of the crab-bolt.
It is welded and fixed in above-mentioned technical proposal, between the steel plate and the wing plate through groove weld seam into a single integrated structure.
When existed concrete bridge post is in the case where changing force status, large eccentric pressuring is produced, pillar is abscissused under this operating mode
Face carrying demand changes, and certain original side tension reinforcement of existed concrete bridge pillar configures deficiency under such conditions, conventional
Reinforcing means be pillar surrounding whole steel clad reinforcement, but this reinforcement means is running into corner post or water tank by elevator
, it is necessary to remove elevator and water tank during the corner post on side, these of dismounting are often difficult in engineering site.The utility model
Steel plate is pasted for one side of large eccentric pressuring post tension arrangement of reinforcement arrangement, the principle that steel plate herein replaces by force according to waiting converts meter
Enter the tension reinforcement needed for this side, it is public according to Bend bearing capacity by biasing post least favorable moment of flexure and axial force combination
Formula calculates the steel plate area of section needed for tight side, is achieved in unilateral steel clad reinforcement.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
The utility model realizes the unilateral steel clad reinforcement of concrete column, can simplify pillar Baogang by structure design
Technique, avoid the processing steps such as dismounting original filled wall needed for surrounding Baogang post, save construction costs, accelerate construction work
Phase；The various unsuitable applications for removing surrounding structure can be applied to simultaneously.
