Description
Technical Field
The utility model relates to the field of buildings, in particular to a connecting structure of a steel column and a concrete column.
Background
Because roofing landscape design's hysteresis quality or reform transform existing building structure, need be connected the steel column of newly-increased steel construction and original concrete column, at present the common method has three kinds: firstly, planting a steel bar and a steel plate in a concrete column to form an embedded part and welding the embedded part with a column base of the steel column; secondly, the upper part of the concrete column is considered to be connected with a steel column during the design, and a column cap and an embedded part are designed to be connected with the upper part of the steel column; thirdly, a short column is made after the concrete column is embedded with the steel bars, and the newly added steel column is connected with the short column. The three methods all require that the section of the original concrete column or column cap is large enough to meet the position of the embedded steel bar.
However, when the concrete column is designed and constructed, the position of a newly-added steel column is uncertain, the size and the shape of the section of a column base are uncertain, and the load of the steel column is unknown, so that the situation that the section of the concrete column is small and the steel bar planting cannot be met may exist. When the concrete column cross-section is less, just can't connect the steel column on the concrete column, if punch on the top of concrete column by force and connect, probably can lead to the fact the destruction to the node at concrete column top to make the concrete column suffer the damage, the node strength of concrete column can receive the influence.
SUMMERY OF THE UTILITY MODEL

In addition, even if do not directly connect between steel column in this scheme and the concrete column, but this scheme steel column will do all can through steel column base steel sheet disperse earlier transmit to the concrete frame roof beam on, because the column cap has been added to the node bottom that concrete frame roof beam and concrete column formed, the column cap collects the power that receives on the concrete frame roof beam again and transmits for the concrete column, the column cap has increased beam column node like this, can effectual transmission power, the concrete column still can carry out stable support to steel column and concrete frame roof beam, whole connection structure's security has been guaranteed.
Steel column and concrete column's connection structure in this scheme does not relate to complicated structure, construction easy operation, and strengthens existing node, has effectively transmitted the internal force.
Preferably, as a modification, the cross-sectional area of the upper portion of the cap is larger than that of the lower portion. Therefore, the upper part of the column cap is wide, the lower part of the column cap is narrow, and the effect that the column cap gathers the force on the concrete frame beam onto the concrete column is better.
Preferably, as an improvement, a plurality of ribbed slabs are fixedly connected between the side surface of the steel column and the steel plate of the column base of the steel column. The floor links together the side of steel column and steel column base steel sheet, and the floor plays the effect of strengthening rib, and the steel column is located more firm stable on the steel column base steel sheet.
Preferably, as an improvement, the connecting piece is a split bolt, the split bolt vertically passes through the concrete frame beam, the top of the split bolt is connected on the top of the steel column base steel plate through a nut, and the bottom of the split bolt is connected on the bottom of the concrete frame beam through a nut. The split bolts are used as connecting pieces, and the mode that the steel column base steel plates and the concrete frame beam are connected together through the split bolts is simple and convenient to construct.
Preferably, as an improvement, the steel column is i-steel, channel steel, H-shaped steel, square steel or round steel. Therefore, the steel columns with corresponding shapes and structures can be selected according to actual conditions.
Preferably, as an improvement, a plurality of ribbed plates are distributed around the steel column. From this, a plurality of floor are connected the steel column all around with steel column base steel sheet, and steel column base steel sheet are connected more firmly stably.
Preferably, as an improvement, the cap is of reinforced concrete structure. Therefore, the column cap structure is firm and stable.
Preferably, as a modification, the bottom of the steel column is welded to the steel column base plate. The welding mode can make the bottom of steel column and the firm of steel column base steel sheet connection.

Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the steel column comprises a steel column 1, a steel column base steel plate 2, a column cap 3, a split bolt 4, a rib plate 5, a concrete column 6, a concrete frame beam 7 and a concrete beam plate 8.
The embodiment is basically as shown in the attached figures 1-2:
a connecting structure of a steel column and a concrete column comprises an original concrete column 6 and an original concrete beam plate 8, wherein the top of the original concrete column 6 is connected with a concrete frame beam 7; still including the steel column 1 that newly adds, concrete frame roof beam 7 pours and is located the top of concrete column 6, and steel column 1 can be I-steel, channel-section steel, H-shaped steel, square steel or round steel, and steel column 1 in this embodiment is the I-steel. The bottom of the steel column 1 is welded with a steel column base steel plate 2. A plurality of rib plates 5 are fixedly connected between the side surface of the steel column 1 and the steel plate 2 of the column foot of the steel column.
