Description

Technical Field

[0001] This invention belongs to the field of anti-backflow technology for steel-concrete composite pipes, and more specifically, relates to a jacking-type anti-backflow device for steel-concrete composite pipes. Background Technology

[0002] In modern building construction, concrete-filled steel tube (CFST) structures are widely used due to their excellent load-bearing capacity and seismic performance. However, concrete pouring is a technical challenge during CFST construction, especially ensuring that the concrete fills the interior of the steel tube column evenly and preventing backflow, which is crucial for the stability and safety of the structure. Traditional concrete pouring methods have many shortcomings, such as uneven concrete pouring, the formation of voids inside the steel tube column, and low pouring efficiency due to concrete backflow. These problems not only affect construction efficiency but may also lead to structural safety hazards.

[0003] To address these issues, the industry has proposed various solutions, such as using specialized pouring equipment, improving concrete mix proportions, and employing special pouring techniques. However, these methods often require complex equipment or are difficult to achieve the desired results in practice. Therefore, it is necessary to develop a jacking-type steel-tube concrete anti-backflow device to improve the efficiency and quality of concrete pouring, ensure that concrete fully fills the interior of the steel tube column, prevent concrete backflow, and enhance construction safety. Summary of the Invention

[0004] In view of this, the present invention provides a lifting steel pipe concrete anti-backflow device, which can prevent concrete backflow during steel pipe concrete transportation, improve construction efficiency and quality, and reduce construction costs.

[0005] This invention is implemented as follows:

[0006] This invention provides a jacking-type steel pipe concrete anti-backflow device, installed on a steel pipe column and a building structure for concrete pouring. The top of the building structure is the floor. The device includes a short pipe, a connecting pipe, and a floor pouring assembly. Both the connecting pipe and the floor pouring assembly are connected to a concrete pump, which delivers concrete into the short pipe and the connecting pipe. The short pipe is welded to the bottom outer wall of the steel pipe column, and the connecting pipe is fixedly connected to the side away from the steel pipe column. The cooperation between the short pipe and the connecting pipe is used to jack up and deliver concrete into the steel pipe column and prevent backflow, ensuring that the concrete fully fills the interior of the steel pipe column. The floor pouring... The components are installed on the floor for zoned concrete delivery. The concrete delivery pump includes a grinding component, a pressurized delivery component, a filtering component, and a defoaming component. It has multiple delivery ports, and the grinding component is installed inside its hopper to mix and grind the concrete to be delivered, ensuring its fineness. The delivery ports are connected to the pressurized delivery component, allowing concrete to be delivered to the steel pipe column and onto the floor. The filtering component is located at the connection point between the grinding component and the pressurized delivery component, used to filter the concrete. The defoaming component eliminates air bubbles in the delivered concrete to prevent cracks from forming in the concrete delivered to the steel pipe column due to trapped air bubbles.

[0007] Based on the above technical solution, the jacking steel pipe concrete anti-backflow device of the present invention can be further improved as follows:

[0008] The short pipe is fixedly connected to the first snap-fit ​​plate at one end away from the steel pipe column. A second snap-fit ​​plate is also provided on the side of the first snap-fit ​​plate away from the steel pipe column. The first and second snap-fit ​​plates are the same size. Multiple protrusions and compression blocks are provided at their connection point. The protrusions and compression blocks match each other to connect the first and second snap-fit ​​plates, with a gap between them. The end of the second snap-fit ​​plate away from the first snap-fit ​​plate is fixedly connected to the connecting pipe. Snap-fit ​​interfaces are provided on both the first and second snap-fit ​​plates. The short pipe, snap-fit ​​interfaces, and connecting pipe are the same size, and their center points are on the same horizontal line. An anti-backflow valve is provided in the gap between the first and second snap-fit ​​plates. The through-hole on the anti-backflow valve corresponds to the holes in the short pipe, snap-fit ​​interfaces, and connecting pipe. An installation groove is provided at the bottom of the anti-backflow valve, corresponding to the bottom wall of the first and second snap-fit ​​plates.

[0009] The short tube has a diameter of 125mm and a length of 100mm; the first and second snap-fit ​​plates are both 300mm in length and width and 15mm in thickness; the connecting tube has a length of 450mm.

[0010] Furthermore, sealing valves are provided at the connection points of the first snap-fit ​​plate and the steel pipe column, and at the connection points of the second snap-fit ​​plate and the connecting pipe. The sealing valves are made of rubber and include a fixing ring and a clamping ring. The fixing ring matches the snap-fit ​​interface on the first and second snap-fit ​​plates and extends protruding towards the short pipe and the connecting pipe. The clamping ring is located on the inner wall of the fixing ring, and its size is larger than that of the clamping ring, extending towards the outer wall of the clamping ring. The inner diameter of the clamping ring is the same as the outer diameter of the short pipe and the connecting pipe, and its inner wall is provided with threads to strengthen the support and fixation of the sealing valves.

[0011] The second snap-fit ​​plate extends into the inner wall of the short pipe and the connecting pipe, and a compression spring is provided inside the position where it abuts against the inner wall of the short pipe and the connecting pipe. The compression spring is used to fix the snap-fit ​​interface to the short pipe and the connecting pipe.

[0012] Furthermore, conical holes are provided at symmetrical positions on the bottom walls where the first and second snap-fit ​​plates are connected. A long rod is provided at the bottom of the anti-backflow valve, the length of which is the same as the height of the mounting groove. The top dimension of the conical hole is smaller than the dimension of the long rod, which is used to support the long rod. A sliding groove is provided on the inner side wall of the structure where the first and second snap-fit ​​plates are connected. A corresponding protrusion is provided on the side wall of the anti-backflow valve, which is used to limit the horizontal position of the anti-backflow valve inside the structure formed by the first and second snap-fit ​​plates. The conical inner wall of the conical hole is made of hard rubber, and a hard spring is provided between the conical hole and the inner wall.

[0013] Furthermore, the anti-backflow valve is a Tesla valve, with a steel plate extending from its top to the exterior of the structure formed by the first and second snap-fit ​​plates. A sealing rubber layer is provided on the exterior of the steel plate to fill the gaps within the structure formed by the first and second snap-fit ​​plates. The steel plate is larger than the mounting groove, allowing the anti-backflow valve to move downwards when subjected to a downward impact force, filling the mounting groove and blocking the snap-fit ​​interface. The anti-backflow valve is oriented in the same direction as the short pipe and perpendicular to the direction of the steel pipe column.

[0014] Furthermore, the connecting pipe is sealed to the output port of the concrete pump through a pump pipe, a clamp, a pipe clamp, and a groove. The outer wall of the connecting pipe near the pump pipe is provided with a clamp, and the pump pipe near the connecting pipe is provided with a pipe clamp. The inner wall of the pipe clamp is provided with a groove that matches the clamp. The clamp is fixedly connected to the output port of the concrete pump.

[0015] The connecting pipe has a curved structure with a curvature greater than that of a circle of the same diameter, which is used to lengthen the concrete conveying path inside the connecting pipe.

[0016] Furthermore, the top of the floor pouring assembly is equipped with multiple rubber tires, each with a limiting hole inside. A long pump pipe, penetrating the rubber tire, is installed inside each limiting hole. Short pump pipes are connected to both sides of the long pump pipe, and a pouring hose is connected to the other end of each short pump pipe. The rubber tires serve to dampen and limit the movement of the long pump pipes, while the short pump pipes perform zoned pouring of the floor pouring assembly. A shock-absorbing component, an elastic band structure, is installed inside the rubber tire and fixed to the interior of the rubber tire with screws. Additionally, a gravity block is filled inside the rubber tire, and its bottom is attached to the floor surface of the building via a pressure pump to prevent displacement of the rubber tire caused by vibrations during concrete transportation.

[0017] Furthermore, the number of steel pipe columns is 4-8, and the outer wall of the steel pipe columns is wrapped with double-layer thermal insulation felt. The outer wall of the double-layer thermal insulation felt is provided with fireproof and flame-retardant cloth. The double-layer thermal insulation felt is used to achieve the thermal insulation effect on the concrete inside the steel pipe columns in winter, and the fireproof and flame-retardant cloth is used to achieve fireproofing of the steel pipe columns.

[0018] An infrared detector is installed on the inner wall of the steel pipe column, and a sensor is fixedly connected to the inner wall of the steel pipe column. The infrared detector is used to test the slump of the concrete inside the steel pipe column in real time, and the sensor is used to monitor the heat of the concrete inside the steel pipe column.

[0019] Furthermore, the connection point between the short pipe and the steel pipe column is configured as a parabolic structure, with the focus of the parabola located at the center point of the steel pipe column.

[0020] Furthermore, the defoaming component includes multiple vibrating tubes, each with a spiral blade wound around its exterior. These blades are connected to a vibrating disc, which generates vibration via a vibrating motor. The vibrating tubes are inserted into the concrete to eliminate air bubbles within the concrete through vibration.

[0056] Furthermore, in the above technical solution, the defoaming component 54 includes multiple vibrating tubes, the outside of which is wound with helical blades, which are multiple in number and connected to a vibrating plate respectively. The vibrating plate generates vibration through a vibrating motor. The vibrating tubes are inserted into the concrete to eliminate air bubbles inside the concrete through vibration.

[0057] Specifically, the principle of this invention is:

[0058] Installation preparation: First, select appropriate short pipes, connecting pipes, and floor slab casting components based on the diameter and length of the steel pipe column. Weld the short pipes to the bottom outer wall of the steel pipe column, ensuring a firm weld.

During the transportation process, the grinding component mixes and grinds the concrete, the pressurized delivery component delivers the concrete into the steel pipe column, the filtration component filters the concrete, and the defoaming component eliminates air bubbles in the concrete.

[0062] Floor pouring: Concrete is delivered to the floor in sections using floor pouring components. The use of rubber tires and shock-absorbing components ensures the stability of the pouring process and reduces vibration.

[0063] Monitoring and Adjustment: The slump and heat of concrete are monitored in real time using infrared detectors and sensors. The concrete mix proportions and delivery parameters are adjusted based on the monitoring results to ensure the quality of the concrete.

[0064] Thermal insulation and fire protection: The outer wall of the steel pipe column is wrapped with double-layer thermal insulation felt and fireproof and flame-retardant cloth is installed on the outer wall to achieve thermal insulation and fire protection in winter;

[0065] Complete the pouring: After the concrete pouring is completed, turn off the concrete delivery pump, remove the connecting pipes and floor pouring components, and carry out the necessary follow-up treatments on the steel pipe columns, such as curing and maintenance.

[0066] By following the above steps, efficient and high-quality pouring of steel-concrete composite pipes can be achieved, while ensuring the safety and environmental friendliness of the construction process.
