Referring to fig. 1 and 2, in the construction process of a reinforced concrete structure building, it is necessary to connect the beam 3 with the column 1, and in the connection of the beam 3 with the column 1, specifically, the purpose of connecting the beam 3 with the column 1 may be achieved by connecting the flange reinforcing bars 31 of the beam 3 to the flanges 111 of the section steel 11 included in the column 1.

In the related art, when the cross beam 3 has two layers of flange-attached steel bars 31, the connection method adopted is: two layers of sleeves 13 corresponding to the two layers of flange-connected steel bars 31 are welded on the flange 111 of the section steel 11 in advance, and then the two layers of flange-connected steel bars 31 are respectively inserted into the corresponding sleeves 13 on site to realize the connection of the flange-connected steel bars 31 and the flange 111.

However, the above-mentioned connection method also has a problem that the welding error of the sleeve 13 causes misalignment of the position of the flange reinforcing bar 31 and the sleeve 13, and the flange reinforcing bar 31 cannot be inserted into the sleeve 13, thereby making it difficult to connect the cross beam 3 and the column 1.

The technical scheme of the application will be further described with reference to specific embodiments and drawings.

Referring to fig. 3 and 4, the beam-column connection structure includes: column 1, bracket 2 and crossbeam 3. The column 1 comprises a section steel 11, the section steel 11 comprises a flange 111 and a horizontal plate 112, the flange 111 is enclosed to form a section steel cavity 14, and the horizontal plate 112 is positioned in the section steel 11 cavity and connected with the inner wall of the flange 111. The bracket 2 is connected to the outer wall of the flange 111, the bracket 2 includes a support plate 21, the support plate 21 includes at least a first support plate 211 and a second support plate 212, the first support plate 211 and the second support plate 212 are disposed opposite to each other along a first direction (a Z-axis direction in fig. 4), and the bracket 2 is disposed corresponding to the horizontal plate 112. The beam 3 includes a flange-connecting steel bar 31, and the flange-connecting steel bar 31 at least includes a first layer of flange-connecting steel bar 311 and a second layer of flange-connecting steel bar 312, where the first layer of flange-connecting steel bar 311 is lapped on the plate surface of the first support plate 211 and connected with the first support plate 211, and the second layer of flange-connecting steel bar 312 is lapped on the plate surface of the second support plate 212 and connected with the second support plate 212.

The beam column connecting structure adopts the bracket 2 as a connecting piece to connect the profile steel 11 with the flange steel bar 31, and specifically comprises the following steps: the bracket 2 is connected with the flange 111, then the first layer of flange connecting steel bars 311 are lapped on the surface of the first supporting plate 211 and connected with the first supporting plate 211, the second layer of flange connecting steel bars 312 are lapped on the surface of the second supporting plate 212 and connected with the second supporting plate 212, and after the first layer of flange connecting steel bars 311 are connected with the first supporting plate 211 and the second layer of flange connecting steel bars 312 are connected with the second supporting plate 212, the purpose of connecting the section steel 11 and the flange connecting steel bars 31 can be achieved, and then the purpose of connecting the upright column 1 with the cross beam 3 can be achieved.

As can be seen from the above description, the purpose of connecting the section steel 11 and the flange steel 31 can be achieved by overlapping the first layer of flange steel 311 on the plate surface of the first support plate 211 and connecting the first layer of flange steel 311 with the first support plate 211, overlapping the second layer of flange steel 312 on the plate surface of the second support plate 212 and connecting the second support plate 212, and the construction method can still press the flange steel 31 to the plate surface of the support plate 21 by means of external force even if the distance between the first layer of flange steel 311 and the second layer of flange steel 312 along the first direction is not equal to the distance between the first support plate 211 and the second support plate 212 along the first direction, resulting in misalignment between the positions of the flange steel 31 and the support plate 21.

Compared with the construction method adopting the sleeve 13 for connection in the related art, if the position deviation of the sleeve 13 and the flange connecting steel bar 31 is larger, the allowable error of the beam-column connection structure provided by the embodiment is larger than that of the construction method adopting the sleeve 13 for connection in the related art in the mode that the flange connecting steel bar 31 cannot be inserted into the sleeve 13 due to the fact that the positions of the steel bars are not aligned with the sleeve, and further the problem that the flange connecting steel bar 31 cannot be inserted into the sleeve 13 due to the larger welding error of the sleeve 13 in the related art is solved, so that the connection between the cross beam 3 and the upright column 1 is simplified.

Based on this, when the cross beam 3 is a reinforced concrete beam and the column 1 is a steel reinforced concrete column, the connection of the reinforced concrete beam and the steel reinforced concrete column can be made simple.

In addition, since the horizontal plate 112 is positioned in the section steel cavity 14 and is connected to the inner wall of the flange 111, the force transmitted from the flange 111 to the horizontal plate 112 can be received. Then, because the bracket 2 is disposed corresponding to the horizontal plate 112, specifically, when the upright 1 is vertically placed, the horizontal plate 112 is located at the corresponding height of the support plate 21, so that the force transmitted from the support plate 21 to the horizontal plate 112 can be also borne. In this way, the horizontal plate 112 strengthens the rigidity of the section steel 11 at the beam-column junction position, ensures that the section steel 11 cannot deform too much due to the overlarge stress of the cross beam 3, and further ensures the safety of the structure.

The connection manner of the bracket 2 and the flange 111 may be welding or bolting, or may be other connection manners having the same effect, which is not limited in the embodiment of the present application. The support plate 21 may be a horizontal steel plate or a steel plate having a small angle with respect to the horizontal plane. The first direction is the longitudinal direction of the pillar 1, and is generally the direction perpendicular to the horizontal plane in actual engineering. The flange-attached steel bars 31 are steel bars that are protruded at one end of the beam 3 and are required to be connected to the flanges 111.

It should be noted that, the rigidity refers to the capability of an object to resist external force without deformation.

Referring to fig. 3 and 4, in the construction of a reinforced concrete structure building, when a reinforced concrete beam is connected to a section steel concrete column, it is necessary to connect a flange reinforcement 31 of the reinforced concrete beam to a flange 111 of the section steel 11 of the section steel concrete column. The construction flow adopting the beam column connecting structure is as follows: firstly, installing the profile steel 11, welding the bracket 2 on the flange 111 according to a design drawing, arranging supporting plates 21 extending along the radial direction of the upright post 1 at the top and the bottom of the bracket 2, adding two steel horizontal plates 112 in the profile steel cavity 14, respectively positioning the two horizontal plates 112 at the top and the bottom of the bracket 2 and welding with the inner wall of the flange 111, hoisting the beam reinforcement cage which is manufactured in advance to a position close to the height of the bracket 2 by adopting a crane, overlapping the flange connection reinforcement 31 in the beam reinforcement cage on the corresponding supporting plate 21, pressing the flange connection reinforcement 31 onto the plate surface of the supporting plate 21 by utilizing a crow bar if a large gap exists between the flange connection reinforcement 31 and the flange connection 111, and finally, erecting a template and pouring concrete, thereby completing the connection of the upright post 1 and the cross beam 3. The radial direction of the column 1 refers to a direction perpendicular to the axis of the column 1.

In some embodiments, referring to fig. 3 and 4, the flange reinforcing bars 31 are welded to the corresponding support plates 21, and the weld 4 is formed between the flange reinforcing bars 31 and the corresponding support plates 21. Since welding is the most reliable connection between two metal objects, the two metal objects can form a whole after being connected, and therefore, the flange-connecting steel bar 31 is welded with the corresponding support plate 21, and the reliability at the joint is higher than that of other connection modes. However, the reliability of the connection of the flange reinforcing bars 31 with the corresponding support plates 21 directly determines the safety of the beam-column connection structure, so that the safety of the beam-column connection structure is improved.

The weld 4 is a metal strip formed along a gap between two metal objects to be welded during welding, and one side of the metal strip is tightly adhered to one of the metal objects, and the other side is tightly adhered to the other metal object.

In some embodiments, referring to fig. 3 and 4, the flange reinforcing bars 31 overlap the upper plate surface of the corresponding support plate 21. Since the flange-connecting bar 31 is connected to the support plate 21 at the construction site, a manual operation method is adopted. However, for manual operation, the worker can construct more conveniently at the upper portion of the support plate 21 than at the lower portion of the support plate 21, so that the construction efficiency can be improved.

In addition, the flange connecting steel bar 31 can receive downward pressure under the actual stress state, when the lap joint mode is welding, the pressure needs to be transmitted to the supporting plate 21 through the welding line 4, when the welding line 4 is positioned on the upper portion of the supporting plate 21, the welding line 4 receives pressure, when the welding line 4 is positioned on the lower portion of the supporting plate 21, the welding line 4 receives tensile force, however, the compressive capacity of the welding line 4 is stronger than the tensile capacity, so that when the flange connecting steel bar 31 is welded on the upper plate surface of the supporting plate 21, the reliability of the joint of the flange connecting steel bar 31 and the supporting plate is further improved, and the safety of a beam column connecting structure is further enhanced.

In some embodiments, referring to fig. 3 and 5, the weld 4 extends along the outer contour of the flange-attached rebar 31. In this way, the actual length of the weld 4 is greater than 2 times the overlap length of the flange reinforcement 31 and the support plate 21, i.e., the actual weld 4 is made longer. However, the longer the weld 4, the higher the reliability of the joint, so the reliability of the joint is further improved, and the safety of the beam-column connection structure is further enhanced.

The outer contour of the flange-attached steel bar 31 refers to the outer edge line of the contact surface between the flange-attached steel bar 31 and the corresponding support plate 21.

In some embodiments, referring to fig. 3, weld 4 includes a first section of weld 41 and a second section of weld 42 located on either side of weld 4 in the radial direction of the rebar, the length of first section of weld 41 and/or second section of weld 42 being no less than 5d, where d is the diameter of flange-attached rebar 31. Wherein 5d is the minimum length of the connection of the welding seam 4 specified in the steel structure design specification, so that the material and labor can be saved on the basis of ensuring the qualified welding quality, the reliability of the joint of the flange connecting steel bar 31 and the supporting plate 21 is ensured, and the welding cost can be saved.

The radial direction refers to the diameter direction of the circumscribed circle of the cross section of the flange-connected steel bar 31, and when the cross section is a circle, the diameter direction of the cross section is the diameter direction of the polygonal circumscribed circle, and when the cross section is a polygon.

In order to improve the construction efficiency, in some embodiments, referring to fig. 4 and 6, the first support plate 211 is shorter than the second support plate 212 in the radial direction of the column 1 and is located at an upper portion of the second support plate 212. Because the connection flange steel bar 31 and the support plate 21 are connected at the construction site by manual operation, the support plate 21 at the lower part is longer than the support plate 21 at the upper part, and when the support plate 21 has multiple layers, the connection flange steel bar 31 can be directly and vertically dropped onto the upper surface of the support plate 21 during construction, so that the construction is more convenient compared with the condition that each layer of support plate 21 has the same length, and the improvement of the construction efficiency is facilitated.

It should be noted that, the difference between the second support plate 212 and the first support plate 211 cannot be less than 5d+20mm, where d is the diameter of the flange-connecting steel bar 31, that is, the adjacent support plate 21 of the next layer is at least 5d+20mm longer than the support plate 21 of the previous layer.

In some embodiments, referring to fig. 4 and 5, the support plate 21 further includes a third support plate 213 and a fourth support plate 214, the third support plate 213 and the fourth support plate 214 are disposed opposite to each other along the first direction, the third support plate 213 is shorter than the fourth support plate 214 along the radial direction of the column 1 and is located at the upper portion of the fourth support plate 214, the flange-connecting steel bar 31 further includes a third flange-connecting steel bar 313 and a fourth flange-connecting steel bar 314, the third flange-connecting steel bar 313 is overlapped on the plate surface of the third support plate 213 and is connected with the third support plate 213, and the fourth flange-connecting steel bar 314 is overlapped on the plate surface of the fourth support plate 214 and is connected with the fourth support plate 214.

In practical engineering, two layers of flange-connecting steel bars 31 are generally arranged at the top and the bottom of the beam 3 at the same time, namely, the beam top is a first layer of flange-connecting steel bars 311 and a second layer of flange-connecting steel bars 312, and the beam bottom is a third layer of flange-connecting steel bars 313 and a fourth layer of flange-connecting steel bars 314. The support plate 21 is added with a third support plate 213 and a fourth support plate 214, and then can be correspondingly connected with the flange connecting steel bars 31. In this way, two layers of flange-connecting steel bars 31 are connected with the supporting plate 21 at the top and the bottom of the cross beam 3, so that the strength of the beam-column connecting structure is increased, and the safety of the beam-column connecting structure is improved.

In some embodiments, referring to fig. 5 and 6, the bracket 2 further includes a bracket web 22 extending along a first direction, the first support plate 211, the second support plate 212, the third support plate 213 and the fourth support plate 214 are all connected to the bracket web 22, the first support plate 211 and the second support plate 212 are disposed near one end of the bracket web 22, and the third support plate 213 and the fourth support plate 214 are disposed near the other end of the bracket web 22.

Because the first supporting plate 211, the second supporting plate 212, the third supporting plate 213 and the fourth supporting plate 214 are all connected to the bracket web 22, the vertical pressure applied to each layer of supporting plates 21 can be transferred to the flange 111 through the bracket web 22, and the vertical bearing capacity of each layer of supporting plates 21 is enhanced. In addition, the bracket web 22 connects the four layers of support plates 21 as a whole, which enhances the overall rigidity of the bracket 2 and can reduce the deformation of the bracket 2 when subjected to external force.

Further, the first support plate 211 and the second support plate 212 are disposed near one end of the bracket web 22, and the third support plate 213 and the fourth support plate 214 are disposed near the other end of the bracket web 22. In this way, the first support plate 211 and the second support plate 212 are just connected with the first layer of flange steel bars 311 and the second layer of flange steel bars 312 of the beam top, and the third support plate 213 and the fourth support plate 214 are just connected with the third layer of flange steel bars 313 and the fourth layer of flange steel bars 314 of the beam bottom, so that the strength of the beam column connecting structure is further increased.

In some embodiments, referring to fig. 3 and 4, the column 1 further comprises a column concrete inclusion 12, the column concrete inclusion 12 is wrapped outside the section steel 11, the section steel 11 further comprises a section steel web 113, the beam 3 further comprises a web penetrating rebar 32, and the web penetrating rebar 32 passes through the section steel web 113 and is anchored within the column concrete inclusion 12.

Because the compressive capacity of the concrete is very strong, the column concrete inclusion 12 is wrapped on the outer side of the section steel 11, so that the compressive capacity of the upright column 1 can be enhanced. Then, the rigidity of the column 1 is increased due to the greater rigidity of the concrete. In addition, the column concrete inclusion 12 also protects the profiled steel 11 from rust corrosion when exposed to air.

Also, since the section steel 11 includes the section steel web 113, and the section steel web 113 is a steel plate, the tensile property of the steel plate is better than that of concrete, so that the tensile property of the column 1 is enhanced. The section steel web 113 is located in the section steel cavity 14 and is connected to the horizontal plate 112 and the flange 111 at the same time, so that the bending resistance of the column 1 is enhanced.

Because the cross beam 3 further comprises the web penetrating steel bars 32, the web penetrating steel bars 32 penetrate through the section steel web 113 and are anchored in the column concrete inclusion 12, and for the cross beam 3, the web penetrating steel bars 32 are added on the basis of the flange connecting steel bars 31, so that the bearing capacity of the cross beam 3 is enhanced. The web penetrating steel bars 32 are anchored in the column concrete inclusion 12, so that the web penetrating steel bars 32 are firmly connected with the upright columns 1, the strength of the beam column connecting structure is further improved, and the safety of the beam column connecting structure is further enhanced.
