Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a concrete feeding conduit for ultra-high frame columns. Background Technology

[0002] The formwork for the vertical structural members (frame columns and reinforced concrete shear walls) and horizontal members (beams and slabs) of the main building frame structure are erected independently, and the concrete is poured independently, referred to as "branch pouring". Before the reinforcement binding of the frame columns and shear walls, the full-span scaffolding for the beams and slabs is erected first. The reinforcement binding of the frame columns and shear walls and the installation of the formwork are carried out. The strength, rigidity and stability of the full-span scaffolding are fully utilized to correct and reinforce the column formwork. When the concrete is poured, a material discharge guide is made and inserted into the bottom of the column from the middle of the stirrups. It is connected to the concrete delivery pipeline through a rubber hose to reduce the impact of the pump pipe on the column formwork. The material is discharged and vibrated layer by layer from bottom to top to ensure that the concrete is poured densely. Currently, for ease of pouring, the concrete feeding duct is made with a diameter appropriate to the frame column diameter and the gaps between the cross stirrups inside the frame column. The length is 7m. The structure of the feeding duct is made by welding a concrete pumping pipe to a steel pipe. A lifting ring is welded to each of the upper two sides. The lifting rings are reliably fixed by steel wire ropes, steel reinforcement cages and tower crane ropes. When in use, the feeding duct is inserted along the gaps between the stirrups in the middle of the frame column section until the bottom of the feeding duct is about 30 cm from the bottom of the frame column. The pouring operation can then begin. When the pouring depth reaches 50 cm, the feeding is stopped and the feeding duct is lifted. A vibrator is then used to compact the concrete. This alternating process completes the pouring operation.

[0003] Currently, the lower end of the material feeding duct has a flat opening structure, which makes it easy for the flat opening structure to get stuck on the stirrups of the steel reinforcement cage when the material feeding duct is inserted. In addition, the pumping process requires intermittent stops to complete the tamping operation, which reduces the speed of the pouring construction. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the lower end of the material feeding conduit has a flat opening structure in the existing technology, which makes it easy for the flat opening structure to get stuck on the stirrups of the steel reinforcement cage when the material feeding conduit is inserted. In addition, the pumping process requires intermittent stops to complete the vibration operation, which reduces the speed of the pouring construction. The proposed conduit is for ultra-high frame column concrete feeding.

[0018] 1. This technical solution utilizes a rotating connecting pipe and pipe body to transport concrete.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] This utility model mainly provides a novel concrete feeding conduit for conveying concrete into the formwork of ultra-high frame columns. The conduit is 8 meters long, 10-15 centimeters in diameter, and 5-8 centimeters thick, with an effective working depth of 7 meters. In use, the conduit is inserted into the formwork after molding. Its upper end is connected to the frame of a high-pressure concrete pump truck or the steel cables of a tower crane at the construction site via a steel wire rope for hoisting. The conduit is gradually raised as the concrete is fed, allowing the concrete to reach the lower part of the frame column formwork.

[0033] The main technical features of this feeding guide are:

[0034] Reference Figure 1-8 The feeding conduit includes a pipe body 1, with a connecting pipe 6 rotatably connected to the upper end of the pipe body 1. The outer diameter of the upper end of the connecting pipe 6 matches the inner diameter of the concrete conveying hose of the pump truck, making it easy to fix with a lock. An annular protrusion 11 is fixedly connected to the pipe wall of the connecting pipe 6 by welding. A positioning ring 12 is fixedly connected to the upper end of the pipe body 1 by welding. The positioning ring 12 contacts the lower end of the annular protrusion 11, and a limiting ring 14 is set at the lower end of the positioning ring 12. The side walls of the limiting ring 14, the positioning ring 12, and the annular protrusion 11 are all fitted with a sleeve 5. The sleeve 5 is fixed to the annular protrusion 11 and the limiting ring 14 by bolts. At this time, the positioning ring 12 connected to the upper end of the pipe body 1 can rotate freely within the annular protrusion 11 and the limiting ring 14. Alternatively, rotating parts such as bearings and bushings with matching diameters can be used to achieve rotation between the connecting pipe 6 and the pipe body 1.

[0035] To ensure a secure connection between the connecting pipe 6 and the pump truck's delivery hose, two arc-shaped blocks 10 are rotatably connected inside the sleeve 5 via pins. Each of the two arc-shaped blocks 10 has a bend 16 at one end, which is fixedly connected by screws. The inner side of the arc-shaped blocks 10 has two anti-slip grooves 15. Multiple windows are opened on the pipe wall of the sleeve 5. A pipe shoe 7 is fixedly connected to the lower end of the pipe body 1. The arc-shaped blocks 10 can be locked with screws. When the arc-shaped blocks 10 are locked, they can clamp the delivery hose. At this time, the delivery hose sleeved on the connecting pipe 6 can be quickly and stably installed and fixed. An extension pipe 13 is fixedly installed at the lower end of the connecting pipe 6. The extension pipe 13 is directly inserted into the upper end of the pipe body 1. This allows concrete to smoothly enter the pipe body 1 without entering the joint between the connecting pipe 6 and the pipe body 1.

[0036] To increase the practicality of the material feeding pipe, a channel for accommodating concrete vibrators is designed. Specifically, two external channels 18 are installed on the side wall of the pipe body 1 for mounting the concrete vibrators. Each external channel 18 consists of two arc-shaped plates 17 and two baffles 2. Two openings are first made in the side wall of the pipe body 1. The excess material from the pipe body 1 produced during this process forms an arc-shaped plate 17. This excess material is then placed in the openings in reverse. The two arc-shaped plates 17 are then fixed in the two openings, forming the two external channels 18. The baffles 2 are fixed at the two openings. When fixed at the openings, the baffles 2 can enclose the flexible shaft of the concrete vibrator. Figure 2 As shown, the head of the concrete vibrator extends out at this time, so that when the concrete is discharged, the concrete vibrator can directly vibrate and compact the concrete. It also rises with the speed of the feeding duct, so that the concrete can be directly vibrated without stopping the feeding.

[0037] Because a pre-installed steel reinforcement cage is required inside the frame column formwork, the stirrups of the reinforcement cage may obstruct the downward movement of the material feeding guide when it is inserted. Therefore, a tube shoe 7 with a larger opening at the top and a smaller opening at the bottom is set at the lower end of the tube body 1. Since the diameter of the upper end of the tube shoe 7 is larger than the diameter of its lower end, the inverted frustum-shaped tube shoe 7 can be smoothly inserted into the reinforcement cage. Two recessed parts 8 are opened on the side wall of the tube shoe 7 to cooperate with the external channel 18. The recessed parts 8 can make the head of the concrete vibrator lower than the lower end of the tube shoe 7, so that the concrete vibrator can be fully inserted into the concrete for vibration. Multiple connecting blocks 9 are set at the upper end of the tube shoe 7, and the side walls of the multiple connecting blocks 9 are all Screws are fitted through round holes. To ensure that the connecting block and the wall of the pipe body 1 are on the same plane, multiple grooves that mate with the connecting block 9 are provided on the outer edge of the lower end of the pipe body 1. A threaded hole is provided on one side of the groove, and the screw is connected in the threaded hole. Bolt connection allows for easy replacement of the pipe shoe 7 or cleaning of the inside of the discharge hose after disassembly. The upper end of the pipe shoe 7 is provided with a positioning slot 19, and the lower end of the pipe body 1 is provided with a positioning protrusion 20 that mates with the positioning slot 19. Two lifting lugs 4 and two fixing plates 3 are fixedly connected to the side wall of the pipe body 1. The fixing plates 3 are used to fix and install the drive motor of the concrete vibrator, and the lifting lugs 4 are used to connect the steel cable on the lifting device.

[0038] Through the design of the above technical solution, the pumped concrete can be directly delivered to the bottom of the frame column formwork. The lower end of the discharge pipe is equipped with a guide shoe 7, which can prevent the discharge pipe from getting stuck with the steel reinforcement cage. Moreover, the concrete is transported by using the rotatable connecting pipe 6 and the pipe body 1. The reciprocating rotation of the pipe body 1 can also cause the concrete vibrator installed in the external channel 18 to rotate. At this time, the concrete vibrator can fully vibrate the delivered concrete, allowing air bubbles in the concrete to be quickly expelled, ensuring the quality of the concrete after solidification.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
