Description

Technical Field

[0001] The utility model relates to the technical field of the connecting structure between the stirrup of a steel reinforced concrete column and a perforated steel plate, in particular to a connecting structure between the stirrup of a steel reinforced concrete column and a perforated steel plate. Background Technique

[0002] A steel section is welded (or cold-pressed) with steel shapes or steel plates, and then the steel and concrete are formed into a whole to jointly bear the load by enclosing the concrete or filling the concrete inside or through connectors. This is generally called a steel reinforced concrete composite structure. The combined work of steel shapes, steel bars, and concrete enables the steel reinforced concrete structure to have the advantages of greater bearing capacity, greater stiffness, and better seismic performance than the traditional reinforced concrete structure. Compared with the steel structure, it has the advantages of good fire resistance, good local and overall structural stability, and steel saving. Targeted promotion and application of such structures are of extremely important significance to the development, optimization, and improvement of the seismic performance of multi-story and high-rise buildings in China.

[0003] During the construction of a steel reinforced concrete column, before pouring the concrete, it is necessary to connect and fix the steel shape and the longitudinal steel bars through stirrups. In addition to the functions of forming a steel bar skeleton and reducing the flexural and extensional length of the longitudinal bars, the stirrups of the steel reinforced concrete column also have an obvious lateral restraint effect on the reinforced concrete surrounded by it. In most designs, stirrups are provided within the web of the I-shaped steel shape, and the connection problem between the stirrups and the steel column needs to be considered.

[0004] The existing practice is usually in accordance with the practice of "Construction of Steel Reinforced Concrete Composite Structures" (national standard atlas 04sg523). The column stirrups pass through the web of the I-shaped steel shape through perforations, and the holes are processed by a drill press and cannot be gas-cut. In the stirrup encryption area, due to the relatively dense stirrup spacing and a large number of perforations, too large an opening area will lead to the weakening of the strength of the I-shaped steel shape web and cause safety problems. When the web thickness is relatively thick and this method is still used, it will lead to difficult opening construction, a longer processing period, a waste of a large amount of manpower and time, and a relatively large cost consumption. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems of difficult opening construction, a longer processing period, a waste of a large amount of manpower and time, and a relatively large cost consumption, and to propose a connecting structure between the stirrup of a steel reinforced concrete column and a perforated steel plate.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] Design a connecting structure for the stirrup and perforated steel plate of a steel reinforced concrete column, which includes a steel section and a round opening. Multiple round openings are processed on the front and back sides of the steel section respectively. An alignment structure is connected to the inner wall of the round opening on the left side of the front. Cross bars are fixedly connected to the left and right sides of the steel section respectively. Round plates are fixedly connected to the outer sides of multiple cross bars. Multiple control structures are connected to the upper and lower sides of the steel section respectively. A stirrup is connected to the inner wall of the control structure. Stirrups are arranged on the outer wall of the steel section. Column longitudinal bars are fixedly connected to the upper and lower sides of the inner wall of the stirrup respectively. The outer wall of the column longitudinal bar is hung and connected to the outer end of the stirrup.

[0008] Preferably, the control structure includes steel plates and through openings. The inner sides of multiple steel plates are fixedly connected to the upper and lower sides of the steel section respectively. Through openings are processed on the inner walls of multiple steel plates. Inclined plates are fixedly connected to the left and right ends of the steel plates respectively.

[0009] Preferably, the inner sides of multiple inclined plates are fixedly connected to the upper and lower sides of the steel section respectively.

[0010] Preferably, the inner wall of the through opening is hung and connected to the inner side of the stirrup.

[0011] Preferably, the alignment structure includes a straight rod and a screw rod. The rear outer wall of the straight rod is inserted into the inner wall of the round opening on the left side of the front. The inner wall of the straight rod is threadedly connected to the outer wall of the screw rod. A round rod is fixedly connected to the front of the screw rod.

[0012] Preferably, the diameter of the round rod is consistent with the inner diameter of the round opening.

[0013] For the connecting structure of the stirrup and perforated steel plate of a steel reinforced concrete column proposed by the present utility model, the beneficial effects are as follows: By making the inner end of the tightened stirrup pass through the through opening on the inner wall of the steel plate in the control structure, the stirrup is in a taut state, the position of the stirrup is fixed, and the opening on the inner wall of the steel plate changes the original opening form on the outer wall of the steel section, ensuring the overall strength of the steel section. At the same time, the inclined plate supports the steel plate, facilitating the opening construction, shortening the processing cycle, saving a large amount of manpower and time, and reducing the cost consumption.

Detailed implementation mode

[0021] The present utility model will be further described below with reference to the accompanying drawings:

[0022] Embodiment 1:

[0023] Please refer to Figures 1-6 : In this embodiment, a connection structure between a tie bar of a steel reinforced concrete column and an opening steel plate includes a section steel 1 and a round hole 4. A plurality of round holes 4 are respectively processed on the front and rear sides of the section steel 1. An alignment structure 3 is connected to the inner wall of the round hole 4 on the left side of the front surface. Cross bars 8 are respectively fixed on the left and right sides of the section steel 1. Round plates 9 are respectively fixed on the outer sides of the plurality of cross bars 8. The cross bars 8 and the round plates 9 are made of steel. A plurality of control structures 2 are respectively connected to the upper and lower sides of the section steel 1. A tie bar 7 is connected to the inner wall of the control structure 2. Stirrups 5 are arranged on the outer wall of the section steel 1. Column longitudinal reinforcements 6 are respectively fixed on the upper and lower sides of the inner wall of the stirrups 5. The outer wall of the column longitudinal reinforcement 6 is hung and connected to the outer end of the tie bar 7.

[0024] The control structure 2 includes a steel plate 201 and a through hole 202. The inner sides of the plurality of steel plates 201 are respectively fixed to the upper and lower sides of the section steel 1. Through holes 202 are processed on the inner walls of the plurality of steel plates 201. Inclined plates 203 are respectively fixed to the left and right side ends of the steel plate 201. The inclined plates 203 play a supporting role for the steel plate 201, which can prevent the steel plate 201 from bending and deforming. The inner sides of the plurality of inclined plates 203 are respectively fixed to the upper and lower sides of the section steel 1. The inner wall of the through hole 202 is hung and connected to the inner side of the tie bar 7;

[0025] By making the inner end of the tensioning 7 pass through the through hole 202 on the inner wall of the steel plate 201 in the control structure 2, the tie bar 7 is in a taut state, the position of the stirrup 5 is fixed, the opening on the inner wall of the steel plate 201 changes the original opening form on the outer wall of the section steel 1, ensuring the overall strength of the section steel 1. At the same time, the inclined plate 203 supports the steel plate 201, facilitating the opening construction, shortening the processing cycle, saving a large amount of manpower and time, and reducing the cost consumption.

[0026] The integral structure 3 includes a straight rod 301 and a screw rod 302. The rear outer wall of the straight rod 301 is inserted into the inner wall of the circular opening 4 located on the left side of the front. The inner wall of the straight rod 301 is threadedly connected to the outer wall of the screw rod 302. The screw rod 302 rotates back and forth through the inner wall of the straight rod 301 under force. A round rod 303 is fixedly connected to the front of the screw rod 302. The round rod 303 facilitates driving the screw rod 302 to rotate back and forth through the inner wall of the straight rod 301. The diameter of the round rod 303 is consistent with the inner diameter of the circular opening 4.

[0027] Working principle:

[0028] Connection of profiled steel with perforated steel plates and various steel bars:

[0029] First, lay the profiled steel 1 flat as a whole. Then, place the stirrup 5 outside the profiled steel 1 (multiple column longitudinal steel bars 6 can be added to the inner wall of the stirrup 5 according to requirements). Then, hang the outer end of the tie bar 7 on the outer wall of the column longitudinal steel bar 6. Subsequently, make the inner end of the tension bar 7 pass through the through hole 202 on the inner wall of the steel plate 201, which makes the tie bar 7 in a taut state and fixes the position of the stirrup 5. The opening on the inner wall of the steel plate 201 changes the original opening form on the outer wall of the profiled steel 1, ensuring the overall strength of the profiled steel 1. At the same time, the inclined plate 203 supports the steel plate 201. Also, when the position of the column longitudinal steel bar 6 is outside the profiled steel 1, the inner side of the tie bar 6 at other positions can be hung on the outer wall of the cross bar 8.

[0030] Fabrication of steel reinforced concrete columns:

[0031] After connecting the profiled steel with various steel bars, set the formwork outside the combined profiled steel. Subsequently, pour concrete into the formwork. After the concrete solidifies, the support of the steel reinforced concrete column is completed.

[0032] Butt joint of profiled steel:

[0033] Insert the outer wall end of the straight rod 301 into the circular opening 4 on the outer wall of the first profiled steel 1. Subsequently, cooperate with the round rod 303 to make the screw rod 302 rotate back and forth through the inner wall of the straight rod 301, adjust the lengths of the straight rod 301 and the screw rod 302. Then, insert the circular opening 4 on the outer wall of the second profiled steel 1 into the outer wall end of the round bar 303, so as to ensure the parallelism of the butt - jointed profiled steel.

[0034] Embodiment 2:

[0035] Please refer to Figures 1-6 : In this embodiment, a connection structure of a tie bar and a perforated steel plate for a steel reinforced concrete column further includes a curved plate 10. The inner walls of the two curved plates 10 are fixedly connected to the left and right sides of the straight rod 301 respectively.

[0036] Working principle:

[0037] When it is necessary to disassemble the straight rod 301, the hand or an external clamping tool can be clamped at the position of the curved plate 10. The force application is facilitated by the shielding and limiting of the curved plate 10, so that the straight rod 301 or the round rod 303 on the other side can be disengaged from the round opening 4 on the outer wall of the profiled steel 1.

[0038] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
