Description

Technical Field

[0001] This application belongs to the field of civil engineering structural technology, specifically the joint between a steel-concrete composite column and a reinforced concrete beam. Background Technology

[0002] The joint between a steel-concrete composite column and a reinforced concrete beam is a critical component of a building structure, and its design directly affects the overall stability and safety of the structure. The steel pipe connection involves the longitudinal reinforcement of the concrete beam passing through the steel pipe, transferring bending moment and shear force through the beam itself. This method uses less steel and has minimal impact on the building, but requires high precision in construction.

[0003] For example, application CN213448916U discloses a connection structure between a steel-concrete composite column and a reinforced concrete beam. This structure includes a steel-concrete composite column, a reinforced concrete beam perpendicular to the steel-concrete composite column, and a connector at the joint between the steel-concrete composite column and the reinforced concrete beam. The connector includes a support plate, which is positioned at the connection joint between the reinforcing bar and the steel pipe and is fixedly connected to the outer circumference of the steel pipe. The support plate has an open upper end and a downwardly concave arc-shaped lower end, forming an arc-shaped groove on its surface. The reinforcing bar is embedded in this groove. Fasteners are provided at the upper end of the support plate for fixing the reinforcing bar to the support plate. This design avoids the problem of difficulty in installing reinforcing bars due to poor processing, and offers advantages such as easy on-site installation of reinforcing bars and ensuring the fixation between the reinforcing bar and the steel pipe at the connection joint.

[0004] However, in this application, the steel bars are fixed by binding, which results in a large number of steel bars, leading to low construction efficiency. Furthermore, the fixing is done by binding wire, which is prone to loosening under the impact of concrete, resulting in structural instability. Utility Model Content

[0005] The purpose of this application is to provide a joint between a steel-concrete composite column and a reinforced concrete beam in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: a steel pipe concrete column and reinforced concrete beam joint, including the main steel pipe column of the equipment, a reinforcing sleeve welded to the outer surface of the steel pipe column, longitudinal steel bar installation grooves opened on the front and rear sides of the reinforcing sleeve, transverse steel bar installation grooves opened on the left and right sides of the reinforcing sleeve, a fixing thread fixedly connected to the outer surface of the reinforcing sleeve, a transverse steel bar fixing ring and a longitudinal steel bar fixing ring slidably connected to the outer surface of the fixing thread, an upper reinforcing ring and a lower reinforcing ring fixedly connected to the upper and lower sides of the reinforcing sleeve, and a transverse steel bar fixing ring limiting ring and a longitudinal steel bar fixing ring limiting ring fixedly connected to the outer side of the reinforcing sleeve.

[0007] By adopting the above technical solution, during the operation of the equipment, the transverse reinforcing bars are passed through the transverse reinforcing bar installation slot and the transverse reinforcing bar installation slot of the steel pipe column, and then the longitudinal reinforcing bars are passed through the longitudinal reinforcing bar installation slot and the longitudinal reinforcing bar installation slot of the steel pipe column. Because the heights of the transverse reinforcing bar installation slot and the longitudinal reinforcing bar installation slot of the steel pipe column are different, it is convenient to insert the transverse and longitudinal reinforcing bars in the middle, and the installation is quick. Then, the transverse reinforcing bar fixing ring and the longitudinal reinforcing bar fixing ring are rotated downwards to press the transverse and longitudinal reinforcing bars to the bottom of the transverse reinforcing bar installation slot, the transverse reinforcing bar installation slot of the steel pipe column, and the longitudinal reinforcing bar installation slot of the steel pipe column, so that the transverse and longitudinal reinforcing bars can be fixed. This device can make the installation of transverse and longitudinal reinforcing bars quick and convenient, improve work efficiency, and raise the transverse reinforcing bar fixing ring and the longitudinal reinforcing bar fixing ring to firmly fix the transverse and longitudinal reinforcing bars and keep the transverse and longitudinal reinforcing bars in a horizontal state, which facilitates subsequent work and ensures the safety, stability and construction convenience of the structure.

[0008] In a preferred embodiment, the inner surface of the steel pipe column is provided with a longitudinal reinforcement installation groove and a transverse reinforcement installation groove, and the outer sides of the longitudinal reinforcement installation groove and the transverse reinforcement installation groove are fixedly connected to the longitudinal reinforcement installation groove and the transverse reinforcement installation groove.

[0009] By adopting the above technical solution, corresponding to the longitudinal and transverse steel bar installation grooves, it is convenient to pass through the longitudinal and transverse steel bars.

[0010] In a preferred embodiment, a through-hole mounting groove for reinforcing vertical ribs is provided above the reinforcing sleeve, and a reinforcing vertical rib is slidably connected to the inner side of the mounting groove.

[0011] By adopting the above technical solutions, installing reinforcing vertical bars can prevent the column from bending under pressure and enhance the load-bearing capacity of the steel-concrete composite column.

[0012] In a preferred embodiment, longitudinal and transverse reinforcing bars are slidably connected to the inner sides of the longitudinal reinforcing bar installation groove and the transverse reinforcing bar installation groove, and reinforcing stirrups are fixedly connected to the outer sides of the transverse and longitudinal reinforcing bars, and concrete is fixedly connected to the inner and outer surfaces of the longitudinal reinforcing bars.

[0013] By adopting the above technical solution, both transverse and longitudinal reinforcing bars can be fixed, and the double fixing increases the stability during construction.

[0014] In a preferred embodiment, the height of the longitudinal reinforcement installation groove and the longitudinal reinforcement installation groove of the steel pipe column is higher than the bottom of the transverse reinforcement installation groove and the transverse reinforcement installation groove of the steel pipe column.

[0015] By adopting the above technical solution, the installation of horizontal and vertical reinforcing bars is facilitated, preventing them from intersecting and blocking each other, and improving work efficiency.

[0016] In a preferred embodiment, the bottom of the transverse steel bar fixing ring limiting ring is slidably connected with a transverse steel bar.

[0017] By adopting the above technical solution, the horizontal rebar fixing ring and the limiting ring can cooperate with the horizontal rebar installation groove to fix the horizontal rebar, so that the horizontal rebar is in a horizontal state, which facilitates subsequent work.

[0018] In a preferred embodiment, the bottom of the longitudinal steel bar fixing ring is slidably connected with a longitudinal steel bar.

[0019] By adopting the above technical solution, the longitudinal reinforcement fixing ring can cooperate with the longitudinal reinforcement installation groove to fix the longitudinal reinforcement, so that the longitudinal reinforcement is in a horizontal state, which facilitates subsequent work.

[0020] In a preferred embodiment, the outer side of the transverse reinforcing bar is slidably connected to a transverse reinforcing bar installation groove and a steel pipe column transverse reinforcing bar installation groove, and the outer side of the longitudinal reinforcing bar is slidably connected to a longitudinal reinforcing bar installation groove and a steel pipe column longitudinal reinforcing bar installation groove.

[0021] By adopting the above technical solutions, the installation of longitudinal and transverse reinforcing bars can be quick and convenient.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application, during the operation of the equipment, the transverse reinforcing bars are passed through the transverse reinforcing bar installation slot and the steel pipe column transverse reinforcing bar installation slot, and then the longitudinal reinforcing bars are passed through the longitudinal reinforcing bar installation slot and the steel pipe column longitudinal reinforcing bar installation slot. Because the heights of the transverse reinforcing bar installation slot and the steel pipe column transverse reinforcing bar installation slot and the steel pipe column longitudinal reinforcing bar are different, it is convenient to insert the transverse and longitudinal reinforcing bars in the middle, and the installation is quick. Then, the transverse reinforcing bar fixing ring and the longitudinal reinforcing bar fixing ring are rotated downwards to press the transverse and longitudinal reinforcing bars to the bottom of the transverse reinforcing bar installation slot, the steel pipe column transverse reinforcing bar installation slot and the steel pipe column longitudinal reinforcing bar installation slot, so that the transverse and longitudinal reinforcing bars can be fixed. This device can make the installation of transverse and longitudinal reinforcing bars quick and convenient, improve work efficiency, and raise the transverse reinforcing bar fixing ring and the longitudinal reinforcing bar fixing ring to firmly fix the transverse and longitudinal reinforcing bars and keep the transverse and longitudinal reinforcing bars in a horizontal state, which facilitates subsequent work and ensures the safety, stability and construction convenience of the structure.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Example:

[0031] Reference Figure 1-4 The steel-concrete composite column and reinforced concrete beam joint includes the main steel-concrete composite column 1 of the equipment. A reinforcing sleeve 2 is welded to the outer surface of the steel-concrete composite column 1. Longitudinal reinforcement installation grooves 9 are opened on the front and rear sides of the reinforcing sleeve 2, and transverse reinforcement installation grooves 10 are opened on the left and right sides of the reinforcing sleeve 2. A fixing thread 3 is fixedly connected to the outer surface of the reinforcing sleeve 2. A transverse reinforcement fixing ring 6 and a longitudinal reinforcement fixing ring 8 are slidably connected to the outer surface of the fixing thread 3. An upper reinforcing ring 4 and a lower reinforcing ring 19 are fixedly connected to the upper and lower parts of the reinforcing sleeve 2. A transverse reinforcement fixing ring limiting ring 5 and a longitudinal reinforcement fixing ring limiting ring 7 are fixedly connected to the outer side of the reinforcing sleeve 2 to facilitate subsequent work and ensure the safety of the structure.

[0032] Reference Figure 1-4During the operation of the equipment, the transverse reinforcing bars 11 are passed through the transverse reinforcing bar installation slot 10 and the transverse reinforcing bar installation slot 18 of the steel pipe column, and the longitudinal reinforcing bars 16 are passed through the longitudinal reinforcing bar installation slot 9 and the longitudinal reinforcing bar installation slot 15 of the steel pipe column. Because the heights of the transverse reinforcing bar installation slot 10, the transverse reinforcing bar installation slot 18 of the steel pipe column, the longitudinal reinforcing bar installation slot 9, and the longitudinal reinforcing bar installation slot 15 of the lower steel pipe column are different, it is convenient to insert the transverse reinforcing bars 11 and the longitudinal reinforcing bars 16 in the middle, and the installation is quick.

[0033] Reference Figure 1-3 Then, rotate the transverse reinforcing bar fixing ring 6 and the longitudinal reinforcing bar fixing ring 8 downwards to press the transverse reinforcing bar 11 and the longitudinal reinforcing bar 16 to the bottom of the transverse reinforcing bar installation groove 10, the transverse reinforcing bar installation groove 18 and the longitudinal reinforcing bar installation groove 9 of the steel pipe column, and the longitudinal reinforcing bar installation groove 15 of the steel pipe column. Only then can the transverse reinforcing bar 11 and the longitudinal reinforcing bar 16 be fixed. This device can make the installation of the transverse reinforcing bar 11 and the longitudinal reinforcing bar 16 quick and convenient, improve work efficiency, and make the transverse reinforcing bar fixing ring 6 and the longitudinal reinforcing bar fixing ring 8 firmly fix the transverse reinforcing bar 11 and the longitudinal reinforcing bar 16 and keep the transverse reinforcing bar 11 and the longitudinal reinforcing bar 16 in a horizontal state, which facilitates subsequent work and ensures the safety, stability and construction convenience of the structure.

[0034] Reference Figure 1-2 The inner surface of the steel pipe column 1 is provided with longitudinal reinforcing bar installation grooves 15 and transverse reinforcing bar installation grooves 18. Longitudinal reinforcing bar installation grooves 9 and 10 are fixedly connected to the outer sides of the longitudinal reinforcing bar installation grooves 15 and 18, respectively. These grooves correspond to the longitudinal reinforcing bar installation grooves 9 and 10, facilitating the passage of transverse reinforcing bars 11 and longitudinal reinforcing bars 16.

[0035] Reference Figure 1-4 A through-hole mounting groove 17 for reinforcing vertical bars is provided above the reinforcing sleeve 2, and a reinforcing vertical bar 13 is slidably connected to the inner side of the mounting groove 17. Installing the reinforcing vertical bar 13 can prevent the column from bending under pressure and enhance the bearing capacity of the steel-concrete composite column.

[0036] Reference Figure 1-4 The longitudinal reinforcement installation groove 9 and the transverse reinforcement installation groove 10 are slidably connected to the inner sides of the longitudinal reinforcement 16 and the reinforcing vertical reinforcement installation groove 17, and the longitudinal reinforcement 16 and the transverse reinforcement 11 are fixedly connected to the outer sides of the reinforcing stirrups 12. The longitudinal reinforcement 16 and the transverse reinforcement 11 can be fixed, and the inner and outer surfaces of the transverse reinforcement 11 and the longitudinal reinforcement 16 are fixedly connected to the concrete 14. The double fixation increases the stability during construction.

[0037] Reference Figure 1-4The height of the longitudinal reinforcement installation groove 9 and the longitudinal reinforcement installation groove 15 of the steel pipe column is higher than the bottom of the transverse reinforcement installation groove 10 and the transverse reinforcement installation groove 18 of the steel pipe column. This facilitates the installation of the longitudinal reinforcement 16 and the transverse reinforcement 11, prevents them from intersecting and blocking each other, and improves work efficiency.

[0038] Reference Figure 1 The bottom of the transverse reinforcement fixing ring limiting ring 5 is slidably connected to the transverse reinforcement 11. The transverse reinforcement fixing ring limiting ring 5 can cooperate with the transverse reinforcement installation groove 10 to fix the transverse reinforcement 11, so that the transverse reinforcement 11 is in a horizontal state, which facilitates subsequent work.

[0039] Reference Figure 1 The bottom of the longitudinal reinforcement fixing ring 8 is slidably connected to a longitudinal reinforcement 16. The longitudinal reinforcement fixing ring 8 can cooperate with the longitudinal reinforcement installation groove 9 to fix the longitudinal reinforcement 16, so that 116 is in a horizontal state, which facilitates subsequent work.

[0040] Reference Figure 1-3 The outer side of the transverse reinforcing bar 11 is slidably connected to the transverse reinforcing bar installation groove 10 and the steel pipe column transverse reinforcing bar installation groove 18, and the outer side of the longitudinal reinforcing bar 16 is slidably connected to the longitudinal reinforcing bar installation groove 9 and the steel pipe column longitudinal reinforcing bar installation groove 15. This makes the installation of the transverse reinforcing bar 11 and the longitudinal reinforcing bar 16 quick and convenient.

[0041] The implementation principle of the steel-concrete composite column and reinforced concrete beam joint embodiment in this application is as follows:

[0042] During equipment operation, the transverse reinforcing bar 11 is passed through the transverse reinforcing bar installation slot 10 and the steel pipe column transverse reinforcing bar installation slot 18, and then the longitudinal reinforcing bar 16 is passed through the longitudinal reinforcing bar installation slot 9 and the steel pipe column longitudinal reinforcing bar installation slot 15. Because the heights of the transverse reinforcing bar installation slot 10, the steel pipe column transverse reinforcing bar installation slot 18, the longitudinal reinforcing bar installation slot 9, and the lower steel pipe column longitudinal reinforcing bar installation slot 15 are different, it is convenient to insert the transverse reinforcing bar 11 and the longitudinal reinforcing bar 16 in the middle, and the installation is quick. Then, the transverse reinforcing bar fixing ring 6 and the longitudinal reinforcing bar fixing ring 8 are rotated downwards to press the transverse reinforcing bar 11 and the longitudinal reinforcing bar 16 into the transverse reinforcing bar installation slot 10 and the steel pipe column longitudinal reinforcing bar installation slot 15, respectively. The transverse reinforcement installation groove 18 and the longitudinal reinforcement installation groove 9 of the steel pipe column, and the bottom of the longitudinal reinforcement installation groove 15, allow the transverse reinforcement 11 and the longitudinal reinforcement 16 to be fixed. This device makes the installation of the transverse reinforcement 11 and the longitudinal reinforcement 16 quick and convenient, improving work efficiency. Furthermore, raising the transverse reinforcement fixing ring 6 and the longitudinal reinforcement fixing ring 8 can firmly fix the transverse reinforcement 11 and the longitudinal reinforcement 16, and keep the transverse reinforcement 11 and the longitudinal reinforcement 16 in a horizontal state, ensuring the safety and stability of the structure.
