Description

Technical Field

[0001] This utility model relates to the field of lock ring beam technology, and in particular to a lock ring beam structure. Background Technology

[0002] The interlocking ring beam is an important retaining structure component in deep foundation pit engineering. It is usually set at the top of the foundation pit and is made of reinforced concrete or steel. It is a closed ring shape, like a safety helmet holding the edge of the foundation pit. One end of the interlocking ring beam is tightly connected to the vertical retaining structure of the support piles and underground continuous wall, while the other end bears and distributes the soil pressure and water pressure loads transmitted from the cap beam, and evenly transmits these forces to the entire support system. This effectively enhances the overall stability of the foundation pit, prevents the pit wall from collapsing, and ensures the safety of foundation pit construction and the stability of the surrounding environment.

[0003] A search revealed Chinese Patent Publication No. CN222252941U, which discloses a lock-type ring beam structure belonging to the field of shaft construction technology. The structure includes a base installation mechanism, with its lower end bolted to the ground and its sides bolted to other base installation mechanisms. An upper installation mechanism is bolted to the upper end of the base installation mechanism, and its upper end and sides are bolted to other upper installation mechanisms. This improved lock-type ring beam structure uses the base installation mechanism to build the base layer of the lock-type ring beam, and installs an upper installation mechanism layer on top of the base installation mechanism to build the supporting structure. After construction, the lock-type ring beam's sidewalls are sealed, allowing for cement filling to enhance its strength. The height of the lock-type ring beam can be adjusted by changing the number of upper installation mechanism layers. The splicing structure simplifies installation, improving construction efficiency and effectiveness. However, due to its height, the connection strength between the ring beam and the lower structure is relatively low, resulting in poor waterproofing performance. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a lock-type ring beam structure, which aims to improve the problems of low connection strength between the ring beam and the lower structure and poor waterproof performance in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a lock-type ring beam structure, comprising a ring beam body, the inner wall of the ring beam body being provided with multiple main reinforcing bars, the outer wall of the main reinforcing bars being provided with multiple stirrups, the top of the ring beam body being provided with a high water-retaining wall, the top of the high water-retaining wall being provided with a concrete capping, the middle of the concrete capping being provided with multiple reinforcing bars, the outer wall of the reinforcing bars being provided with multiple stirrups, the middle of the reinforcing bars being provided with embedded parts, the bottom surface of the ring beam body being provided with multiple vertical connecting bars, and the outer wall of the high water-retaining wall being provided with a guardrail mechanism, the guardrail mechanism being used to prevent unauthorized personnel from approaching.

[0006] Through the above technical solution: the ring beam, as the basic frame of the entire structure, is cast from high-strength concrete, possessing excellent compressive and deformation resistance. Multiple main reinforcement bars are evenly distributed on the inner wall of the ring beam, providing strong longitudinal tensile strength and effectively enhancing the overall stability of the structure. Multiple stirrups are tightly wrapped around the outer wall of the main reinforcement bars, and these stirrups are securely connected to the main reinforcement bars through binding, forming a stable skeleton that restrains the displacement of the main reinforcement bars, preventing buckling under stress. This also improves the confinement performance of the concrete and enhances the shear resistance of the ring beam. A high retaining wall, also cast from concrete, is installed at the top of the ring beam, effectively preventing rainwater from seeping into the structural foundation below the ring beam. To provide excellent waterproof protection, the top of the high retaining wall is equipped with a concrete coping. The concrete coping enhances the strength of the top of the high retaining wall. Multiple steel bars are evenly distributed in the middle of the concrete coping to strengthen the continuity and integrity of the concrete coping. Multiple stirrups are set on the outer wall of the steel bars, which effectively restrain the steel bars and ensure the stability of the concrete coping under stress. Embedded parts are set in the middle of the steel bars, which provide reliable connection points for the subsequent installation of the railing. Multiple vertical connecting bars are set on the bottom surface of the ring beam, which penetrate into the foundation structure below to achieve a firm connection between the ring beam and the foundation, effectively transferring the load borne by the ring beam to the foundation and ensuring the stability and safety of the entire structure.

[0007] As a further description of the above technical solution:

[0008] The guardrail mechanism includes structural rods, which are set at both ends of the ring beam body. A crossbar is fixedly connected between the middle of two adjacent ring beam bodies, and a top rod is fixedly connected between the top of two adjacent ring beam bodies. Multiple spacer rods are fixedly connected to the outer wall of the crossbar. A welded rod is fixedly connected to the lower end of the spacer rod, and the other end of the welded rod is fixedly connected to an embedded part. A pressure rod is fixedly connected to the outer wall of the high retaining wall.

[0009] Through the above technical solution: the structural rods have excellent resistance to compression and lateral impact. They are vertically installed at both ends of the ring beam body. The horizontal rods fixedly connected in the middle between two adjacent ring beam bodies, together with the top rods, form a lateral support with good rust and corrosion resistance. The horizontal rods and structural rods are connected by welding to ensure connection strength. Multiple spacer rods are evenly distributed on the outer wall of the horizontal rods to ensure that the protective gaps meet safety standards. The lower end of the spacer rod is fixedly connected to a welded rod, and the other end of the welded rod is fixedly welded to the embedded part, effectively enhancing the overall rigidity of the guardrail. The outer wall of the high water retaining wall is fixedly connected to a pressure rod, which is arranged horizontally along the high water retaining wall. The pressure rods and spacer rods are connected by welding to form a grid structure, which can effectively disperse external impact forces.

[0010] As a further description of the above technical solution:

[0011] Warning signs are fixedly connected to the outer wall of the crossbar.

[0012] Through the above technical solution, the warning signs fixedly connected to the outer wall of the crossbar have reflective properties, and can effectively attract people's attention through light reflection at night or in dimly lit environments.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the high retaining wall is covered with a plaster layer.

[0015] The above technical solution involves a plaster layer installed on the outer wall of the high retaining wall, which effectively prevents the concrete surface of the high retaining wall from being damaged by weathering and rainwater erosion.

[0016] As a further description of the above technical solution:

[0017] The vertical connecting ribs are placed in two staggered rows.

[0018] Through the above technical solution, the vertical connecting bars are placed in a double-row staggered manner, which can effectively avoid stress concentration at the same cross section, so that the load borne by the ring beam can be transferred more evenly to the foundation structure below. The upper end of the vertical connecting bars is firmly connected to the main bars and stirrups in the ring beam, and the lower end extends into the foundation structure. Then, through concrete pouring, an integrated force transmission system is formed, which greatly enhances the connection strength and collaborative working ability between the ring beam and the foundation, and effectively improves the seismic performance and stability of the entire structure.

[0019] As a further description of the above technical solution:

[0020] The diameter of the main reinforcement bar is 25 millimeters.

[0021] The above technical solution provides a main reinforcement bar with a diameter of 25 mm, which has high yield strength and tensile strength, as well as good ductility and seismic performance.

[0022] As a further description of the above technical solution:

[0023] The main reinforcing bars are arranged in a five-longitudinal and four-horizontal configuration.

[0024] The above technical solution involves arranging the main reinforcement bars in a five-longitudinal-four-horizontal pattern to form a stable skeleton network. This network can meet the mechanical performance requirements of the ring beam when it is subjected to vertical loads, lateral earth pressure, and external forces, effectively resisting deformation and ensuring the structural safety of the ring beam.

[0025] As a further description of the above technical solution:

[0026] The cross-sectional dimensions of the main body of the ring beam are 800 x 500 mm.

[0027] Through the above technical solution, the cross-sectional dimensions of the ring beam are 800 x 500 mm, which can effectively resist lateral earth pressure and horizontal loads, and reliably transfer the load from the superstructure to the foundation.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the double-row staggered arrangement of vertical connecting bars significantly improves the connection strength with the lower structure. The integrated water-retaining structure of high water-retaining wall, concrete capping and plaster layer greatly improves the waterproof performance. Standardized embedded parts enable the rapid installation and dismantling of the guardrail mechanism. The detachable structure design greatly improves the material recycling rate and reduces construction costs. The modular construction process greatly shortens the construction period.

[0030] 2. In this utility model, structural rods are located at both ends of the ring beam body to ensure the stability of the railing and determine the installation position of the railing. Horizontal bars and top bars are set perpendicular to the structural rods to form the overall frame of the railing. The spacer bar array is set so that the gaps are small and it has a good barrier and protection effect. The welded bar is located at the middle and lower end of the spacer bar and is welded and fixed to the embedded part. The pressure bar is fixed to the outer wall of the high water retaining wall to press the lower end of the spacer bar, realizing the overall fixation of the guardrail mechanism and facilitating the disassembly and recycling in the later stage.
