[0019] The specific embodiments of the utility model will be described below in combination with the drawings.

[0020] As Figure 1 , Figure 2 shown, the steel column and concrete beam connecting joint of the utility model mainly includes steel web 1, steel flange plate 2, beam longitudinal reinforcement 5 and column longitudinal reinforcement 6, I-shaped connecting piece 3 and vertical rib plate 4 and the like structure.

[0021] Among them, steel web 1 and steel flange plate 2 are the steel structure inside steel column, steel web 1 has four and is cross-shaped distribution, is equipped with a steel flange plate 2 at the end of each steel web 1, the end of steel web 1 is connected with the middle part of steel flange plate 2, and steel web 1 is perpendicular to steel flange plate 2.

[0022] In order to facilitate the connection of beam longitudinal reinforcement 5, I-shaped connecting piece 3 is arranged on the outer side of steel flange plate 2, and the arrangement of I-shaped connecting piece 3 is determined according to the position of the joint.When three beams connected with the steel column form a T-shaped structure, only I-shaped connecting piece 3 needs to be arranged on the corresponding three steel flange plates 2; when two beams connected with the steel column form an L-shaped structure, only I-shaped connecting piece 3 needs to be arranged on the corresponding two steel flange plates 2; as Figure 1 , Figure 2 shown, when four beams connected with the steel column form a cross-shaped structure, I-shaped connecting piece 3 is arranged on the four steel flange plates 2 respectively.

[0023] Among them, I-shaped connecting piece 3 is in horizontal state and perpendicular to steel flange plate 2.

[0024] I-shaped connecting piece 3 includes connecting piece web, connecting piece lower flange and connecting piece upper flange, connecting piece web is in vertical state, and connecting piece lower flange and connecting piece upper flange are in horizontal state.The inner end of connecting piece web, connecting piece lower flange and connecting piece upper flange is welded with the outer side of steel flange plate 2 at the same time.

[0025] For the concrete beam, the beam longitudinal reinforcement 5 at the bottom is connected with the connecting piece lower flange, and the beam longitudinal reinforcement 5 at the top is connected with the connecting piece upper flange, when the beam longitudinal reinforcement 5 is connected with the flange of the connecting piece, the end of the beam longitudinal reinforcement 5 and the flange of the connecting piece form a certain length of lap joint structure, and are connected and fixed by welding.

[0026] Since the width of the I-shaped connector 3 is smaller than the width of the concrete beam, the beam longitudinal reinforcement 5 located at the middle part corresponding to the position of the I-shaped connector 3 is connected with the I-shaped connector 3, and the beam longitudinal reinforcement 5 located at the two sides directly penetrates the web plate 1 of the profile steel.

[0027] In order to facilitate the connection of the column longitudinal reinforcement 6, a vertical rib plate 4 is arranged on the outer side of the steel flange plate connected with the I-shaped connector 3. The vertical rib plate 4 is parallel to the profile steel flange plate 2, and the lower end of the vertical rib plate 4 extends below the lower flange of the connector, and the upper end of the vertical rib plate 4 extends above the upper flange of the connector.

[0028] The over-reinforcement hole 9 is a vertical long hole, and the beam longitudinal reinforcement 5 located at the two sides and the column longitudinal reinforcement 6 located at the two sides penetrate the corresponding over-reinforcement hole 9 on the web plate.

[0029] For the steel column, the column longitudinal reinforcement 6 located at the upper part of the joint is connected with the upwardly extending part of the vertical rib plate 4, and the column longitudinal reinforcement 6 located at the lower part of the joint is connected with the downwardly extending part of the vertical rib plate 4. When the column longitudinal reinforcement 6 is connected with the vertical rib plate 4, the end of the column longitudinal reinforcement 6 and the vertical rib plate 4 form a lap joint structure with a certain length, and are connected and fixed by welding.

[0030] Since the width of the vertical rib plate 4 is smaller than the width of the steel column, the column longitudinal reinforcement 6 located at the middle part corresponding to the position of the vertical rib plate 4 is connected with the vertical rib plate 4, and the column longitudinal reinforcement 6 located at the two sides directly penetrates the joint position.

[0031] Since most of the welding construction is carried out on the outer side of the profile steel flange plate 2, the welding operation can be greatly facilitated, and the welding quality can be easily ensured.

[0032] Among them, the column longitudinal reinforcement 6 is lapped on the outer side of the vertical rib plate 4, and the beam longitudinal reinforcement 5 is lapped on the upper surface of the lower flange of the connector or the upper surface of the upper flange of the connector, so that the welding point is located on the outer side of the vertical plane or the upper side of the horizontal plane, facilitating the welding operation.

[0033] In order to further facilitate the welding operation, the length of the lower flange of the connector is greater than the length of the web plate of the connector and the upper flange of the connector. When the lower beam longitudinal reinforcement 5 is welded with the lower flange of the connector, there is no upper flange of the connector above to block the operation of the construction personnel, and when the upper beam longitudinal reinforcement 5 is welded with the upper flange of the connector, there is also no structure above to block the operation of the construction personnel.

[0034] The vertical rib plate 4 penetrates the I-shaped connector 3 in the vertical direction, and the part between the upper flange of the connector and the lower flange of the connector strengthens the structural strength of the upwardly and downwardly extending parts of the vertical rib plate 4.

[0035] In one embodiment of the utility model, a plurality of steel hoops 7 are arranged between the two adjacent vertical rib plates 4, the steel hoops 7 are located at the outer side of the column longitudinal beam, the steel hoops 7 are welded with the corresponding column longitudinal reinforcement 6, the column longitudinal beam is fixed and limited through the steel hoops 7, and the structural strength of the joint part is strengthened.

[0036] In Figure 1 、 Figure 2 The body of the steel hoop 7 is a right angle structure, and the two ends of the steel hoop 7 are respectively bent inward, and the two ends of the steel hoop 7 are welded with the vertical rib plate 4.

[0037] In one embodiment of the utility model, the column horizontal rib plate 8 is arranged on the steel web plate 1, the column horizontal rib plate 8 is in a horizontal state, and there are four column horizontal rib plates 8, each of which is located between two adjacent steel web plates 1 and connected with the surfaces of the two steel web plates 1, and the edges of the column horizontal rib plate 8 are connected with the inner side surfaces of the steel flange plates 2, so that the structural strength of the cross steel bone at the joint is strengthened.

[0038] Further, the column horizontal rib plate 8 has two and is consistent with the height of the connecting piece lower flange and the connecting piece upper flange, so that the structural strength of the connecting piece lower flange and the connecting piece upper flange is strengthened.

[0039] When the position error and the size error of the steel structure in the steel bone column occur, the positions of the beam longitudinal reinforcement 5 and the column longitudinal reinforcement 6 are only needed to be adjusted to correspond to the I-shaped connecting piece 3 or the vertical rib plate 4, and the rib holes 9 are needed to be opened on the steel web plate 1 according to the needs, the number of the holes is small, and the hole positions are easy to determine.

[0040] After the joint structure of the utility model is adopted, the construction operation can be greatly facilitated, the construction efficiency can be improved, and the construction quality can be effectively ensured.
