Description
Technical field
The present invention relates to building field, particularly a kind of node of I-shaped steel reinforced concrete conversion beam lift column.
Background technology
Conversion layer：From lower part because plane is different using function, which adopts with lower part on the top of building floor
With different structure types, and pass through the floor and carry out structure conversion, then the floor is known as structural transition layer.
Beam lifts column：Due to a certain floor large space demand or due to upper and lower floor use function difference, upper strata certain
A little columns fail to extend to lower floor, but are supported on floor girder.Namely column is not taken root from basis, is supported directly on beam.It is logical
This column is often called beam upper prop, code name LZ.The beam of backbar upper prop, commonly referred to as conversion beam.
Girder with rolled steel section en cased in concrete lift Column border node referring generally to national building standard design atlas 04SG523 require to be designed with
Construction.Column to ensure transition mast indulges the reliable anchoring of muscle bottom, needs column to be allowed to indulge muscle and pass through in the trepanning of the I-steel edge of a wing and anchors into
It is too big to the flange section weakening of the I-steel of conversion beam when more column, which indulges muscle, to perforate in concrete, it will directly affect
To conversion beam or even the safety of total.
Invention content
The technical problem to be solved in the present invention is to provide a kind of node of I-shaped steel reinforced concrete conversion beam lift column,
Beam upper prop is changed to profile steel concrete column by common concrete column, column is made to indulge muscle quantity and is greatly reduced, a small amount of column is indulged muscle edge and turned
The edge of a wing for changing beam type steel is passed through in the concrete inside the shaped steel for anchoring into conversion beam, big so as to avoid the section steel flange of conversion beam
The perforation of amount improves bearing capacity and safety, while has been also convenient for construction.
The invention is realized in this way：A kind of node of I-shaped steel reinforced concrete conversion beam lift column, turns including concrete
Change beam and beams of concrete upper prop, pre-buried one first I-steel, first I-steel include structure in the concrete conversion beam
Into the first top flange of I-shaped, the first web and the first lower flange；A pre-buried column inner mold in the beams of concrete upper prop
Steel, shaped steel is vertical in the column and is fixedly connected on first top flange, is located in the column in the beams of concrete upper prop
The first column of complex root is arranged at left and right sides of shaped steel and indulges muscle, and left and right two of the muscle along first top flange is indulged per first column
Outside portion anchors into the first web both sides；It is located in the beams of concrete upper prop in the column on the outside of two before and after shaped steel and symmetrically sets
There is the second column of complex root to indulge muscle, indulged per second column after muscle passes through first top flange and anchor into the first web both sides.
Further, the concrete conversion beam, which further includes, a plurality of is symmetrically disposed on putting more energy into for the first web both sides
Plate, and at least two symmetrically arranged stiffeners are located at the underface projected position on the described second preceding edge of a wing, while at least
Two symmetrically arranged stiffeners are located at the underface projected position on the edge of a wing after described second.
Further, shaped steel is the second I-steel in the column, and second I-steel includes the second preceding edge of a wing, the second abdomen
The edge of a wing after plate and second；The both ends that the second preceding edge of a wing and the second rear wing edge are vertically connected to second web are formed
" work " font.
Further, second web and first web are located at same perpendicular, and the second preceding edge of a wing
Perpendicular to first web.
Further, the edge of a wing is arranged with a plurality of shear studs behind the described second preceding edge of a wing and second.
The invention has the advantages that：The present invention provides a kind of node of I-shaped steel reinforced concrete conversion beam lift column, leads to
Crossing, which increases shaped steel in the column, reduces the quantity that second column indulges muscle, and only a small amount of second column indulges muscle from described
One top flange anchors into the both sides of first web after passing through, while every first column is indulged muscle along first top flange
Two outside portions of left and right anchor into the first web both sides, reduce the weakening to first top flange section, improve described
The bearing capacity of first I-steel, and then improve degree of safety.
