Background technology
, it is necessary to which substantial amounts of embedded part, inevitably needs embedded ribs, traditional way in the connection of concrete and steel construction
Usually steel plate, which is embedded in concrete, carries out steel construction.Connecting node has pre-embedded steel slab the requirement in intensity, it is however generally that
The more big then intensity of the area of steel plate structure is bigger, but the size of pre-buried steel construction is limited by concrete, and steel construction cannot surpass
Go out the scope of concrete.For example, for some different in nature concrete columns, since some side of concrete column is relatively narrow, then it is embedded in
Steel construction in it may be pierced by existing smaller by the pre-buried area of existing steel construction and can not meet the requirement of bonding strength.
During old housing reform is made, such as need to carry out the connection of steel construction based on existing concrete column, it is clear that
Existing pre-buried steel construction is unworkable as the method for steel node.In addition, tradition uses disposable common split bolt, intensity
Low, screw thread and welding point are fragile, and Construction Cost is high.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of rational in infrastructure, bonding strength higher concrete and steel structure connection
Node and its construction method.
To achieve the above object of the invention, concrete of the present invention-high-strength connection joints of steel structure, including concrete column and bag

Parallel, spacing is uniformly arranged, and the high-strength steel threaded bar on two layers is arranged in a mutually vertical manner or is arranged in parallel respectively.
Specifically, the girder steel includes top flange plate, web, rod iron, and the web is arranged on the top flange plate and institute
It states and connects the top flange plate and the high-strength steel bar respectively between high-strength steel bar, wherein the parallel upper limb of the high-strength steel bar
Plane where listrium, the web are less than the top flange perpendicular to the top flange plate, rod iron, the diameter of the rod iron
The width of plate.
Specifically, the rod iron, high-strength steel threaded bar be high-strength steel bar, wherein the high-strength steel bar for 420MPa,
460MPa, 490MPa, 550MPa, 780MPa grades of steel.
Particularly, the web is wave webs, wherein the cross section of the wave webs is trapezoidal cross-section structure, sine
Curve, cosine curve, rectangular cross section, circular section or triangular section structure.
Further, the top flange plate and the web infall are equipped with several high-strength ribs, the rod iron and the abdomen
Plate infall is equipped with several ribs, and the ribs is set along rod iron length direction, and it is wide that the web is arranged on top flange plate
The middle position of degree, the diameter of the rod iron are less than the width of the top flange plate, a diameter of upper limb of the rod iron
The 1/5 to 1/2 of listrium width.
Further, several protrusions, the array of protrusions are equipped on the outside of the top flange plate and on the high-strength steel bar
Shape is arranged.
Further, the tangent setting in outer surface of the ribs between the rod iron and the web and the rod iron, institute
It is 60 ° to state the angle between ribs and the web,
To achieve the above object of the invention, the construction method of concrete of the present invention-high-strength connection joints of steel structure is by steel plate bag
It overlays on concrete column, opposite position sets high-strength steel threaded bar through hole, institute on the concrete column and the steel plate
Steel plate is stated to be fixedly connected by high-strength steel threaded bar with the concrete column.
Further, further include and be attached steel construction and the steel plate.
Concrete of the present invention-high-strength connection joints of steel structure employs the structure coated steel plate outside concrete, similary
Concrete column structure in the case of, the entire area of steel plate is larger, adds the intensity of steel connection structure, while high-strength steel screw thread
Stick intensity height, uniform force, stability is good, operation is simple.For in strengthening reconstruction, it may be convenient to realize, beam column rigid connection or
Person is hinged, and can bear the pulling force of bigger；When connected pillar section is smaller, using such section, can solve using biography
During system scheme, the problem of anchor bar length is inadequate；Such node, can also use in various polymorphic structures.Screw rod is logical
Screw thread, screw thread are made of cold-extrusion technology, and screw strength improves, and is not easy stripped thread.Screw pitch is easy to clean compared with plain bolt people,
Broadband buttress thread impact resistant.The common split bolt being embedded in silicon can be substituted, it is more that whole bolt can all take out repetition
Secondary use reduces the waste of raw material, reduces cost.Avoid a silicon table and and bolt screw thread repair process process, generate
Bolt hole that microlith silicon can be used to mend packing is real.
In addition, the connection of concrete-steel structure is realized for structured concrete column structure.
