Description
Technical Field
The utility model belongs to reinforced concrete frame structure field especially relates to a connection structure of steel shotcrete and concrete frame structure node.
Background
In the civil engineering field, a reinforced concrete frame structure is the most common structural form, and with the diversity of building function requirements, the appearance of irregular shapes (overlong structures or local protrusions) and irregular column nets is more and more. During structural design analysis, the standard requirements are often difficult to meet only according to pure frame structural design, and a design method for increasing steel support members is reasonable. The connection of the steel support members in the frame beam column joint area is also important.
The existing engineering example has no better processing mode for the situation, so that the steel bars in the node area of the concrete beam column are dense, the concrete is difficult to pour, and the connection effectiveness of the nodes is difficult to ensure. The traditional method is to arrange profile steel in a floor provided with a steel support and an upper layer and a lower layer of adjacent concrete columns, arrange the profile steel in a frame beam, and ensure that the profile steel in the frame beam and the frame column is only structurally connected with the concrete member.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes prior art exists not enough, has solved the problem that current connected mode structure is complicated, the construction is complicated and the cost is high, aims at providing the connection structure of a steel shotcrete and concrete frame structure node, the utility model discloses a set up T type connected node, simplify the structure of current node, construction convenience and cost are cheap.
In order to solve the technical problem, the utility model discloses a technical scheme does: a connecting structure of a steel support and a concrete frame structure node comprises a frame column and a frame beam, wherein the frame column and the frame beam are arranged in a criss-cross mode, a T-shaped connecting piece is pre-embedded at the node of the frame column and the frame beam, the T-shaped connecting piece comprises transverse section steel and longitudinal section steel, the transverse section steel and the longitudinal section steel are mutually perpendicular and fixedly connected, and an upper connecting plate extends outwards from the right angle of the transverse section steel and the longitudinal section steel;
and the middle part of the frame beam is embedded with a bottom connecting piece, the bottom connecting piece extends outwards to form a lower connecting plate, and the lower connecting plate is fixedly connected with the upper connecting plate through supporting section steel.
Furthermore, the extending length of the T-shaped connecting piece in the frame beam is 2hb, and the extending length of the T-shaped connecting piece in the frame column is 2hc, wherein hb is the section height of the section steel beam, and hc is the section height of the section steel column.
Furthermore, connecting holes are preset in the upper connecting plate and the lower connecting plate, and the support section steel is connected with the upper connecting plate and the lower connecting plate through bolts.
Compared with the prior art, the utility model following beneficial effect has: the utility model discloses optimize current structure, only set up T type connected node in the frame node intra-area, guaranteed the atress analysis in node area, outside the make full use of area of shaped steel, rely on the intensity of concrete member self to resist the deformation, satisfy the atress analysis to reach and practice thrift steel, the purpose of convenient construction.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of a T-shaped connector.
In the figure: 1 is the frame post, 2 is the frame roof beam, 3 is T type connecting piece, 31 is horizontal shaped steel, 32 is vertical shaped steel, 33 is the upper junction plate, 4 is the support shaped steel, 5 is the bottom connecting piece, 6 is the lower connecting plate.
Detailed Description
As shown in figures 1 and 2, the connecting structure of the steel support and concrete frame structure node comprises a frame column 1 and a frame beam 2, wherein the frame column 1 and the frame beam 2 are arranged in a criss-cross mode, a T-shaped connecting piece 3 is pre-embedded at the node of the frame column 1 and the node of the frame beam 2, the T-shaped connecting piece comprises a transverse section steel 31 and a longitudinal section steel 32, the transverse section steel 31 and the longitudinal section steel 32 are fixedly connected in a mutually perpendicular mode, and an upper connecting plate 33 extends outwards from the right angle of the transverse section steel 31 and the longitudinal section steel 32.
The middle part of the frame beam 2 is pre-embedded with a bottom connecting piece 5, the bottom connecting piece 5 extends outwards to form a lower connecting plate 6, connecting holes are pre-arranged on the upper connecting plate 33 and the lower connecting plate 6, and the support section steel 4 is connected with the upper connecting plate 6 and the lower connecting plate 6 through bolts. The lower connecting plate 6 and the upper connecting plate 33 are fixedly connected through the supporting section steel 4.
Through set up the steel shotcrete in concrete frame structure, set up T type node built-in fitting in the junction of frame node, it is more convenient not only to make reinforcement when being under construction, reduces just quantity, makes the construction also more convenient simultaneously.
The extending length of the T-shaped connecting piece 3 in the frame beam 2 is 2hb, and the extending length in the frame column 1 is 2hc, wherein hb is the section height of the section steel beam, and hc is the section height of the section steel column. Set up T type connected node in the frame node intra-area, this kind stretches into the atress analysis that length can guarantee the node area, outside the make full use of area of shaped steel, relies on concrete member self intensity to resist the deformation, satisfies the atress analysis to reach and practice thrift steel, the purpose of convenient construction.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
