Description

Technical Field

[0001] The present invention relates to the field of concrete pouring applications, and more particularly to a concrete automatic chute device and a construction method thereof. Background Art

[0002] As Figure 1 shown, a super high-rise building includes a core tube 1 and mega columns 2. During the construction of the core tube, a self-climbing steel platform 3 will be set up, and a concrete distributor 4 will be installed on the steel platform for concrete pouring. When constructing the mega column 2, the concrete distributor 4 is often used for distributing concrete. The mega column 2 is provided with a profiled steel 5, and concrete is covered outside the profiled steel 5. In order to facilitate the adjustment of the concrete distribution position, a chute is often arranged below the distribution pipe 6 of the concrete distributor for the distribution operation. The chute is adjusted manually, and the height difference between the discharge end of the chute and the concrete pouring surface is in a changing state, which is not easy to control and easily causes concrete segregation, affecting the quality of the concrete structure. Summary of the Invention

[0006] The flow interception device is arranged in the chute and can move along the length direction of the chute;

[0007] The flow interception device includes a concrete storage bin, and the top of the conduit device is communicated with the concrete storage cavity;

The processor can calculate the actual height difference between the discharge port of the conduit device and the concrete pouring surface according to the measurement data of the rangefinder, and the processor can control the telescopic pipe of the conduit device to expand and contract so that the actual height difference matches the preset height difference threshold.

[0015] Further, a baffle on one side of the concrete storage bin facing the lower part of the chute can be opened and closed. When it is opened, the concrete moves downward along the chute.

[0021] In step 2, during the concrete pouring process, control the length of the telescopic pipe of the conduit device so that the height difference between the bottom end of the conduit device and the concrete pouring surface meets the requirements. Specifically:

[0022] The rangefinder collects the distance information between it and the concrete pouring surface and transmits the distance information to the processor;

[0023] The processor calculates the actual height difference between the discharge port of the conduit device and the concrete pouring surface;

[0036] The following further details the concrete automatic chute device and its construction method provided by the present invention with reference to the accompanying drawings and specific embodiments. In combination with the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0037] Embodiment 1

[0038] Combined with Figure 2 and Figure 3 As shown, the automatic concrete chute device provided in this embodiment includes a chute 10, a flow interception device 20, and a conduit device 30. The flow interception device 20 is arranged in the chute 10 and can move along the length direction of the chute 10. The flow interception device 20 includes a concrete storage bin 21, and the top of the conduit device 30 communicates with the concrete storage cavity. After the concrete on the chute 10 slides into the concrete storage bin 21, it is output through the conduit device 30. The conduit device 30 includes a telescopic pipe 32, and the telescopic pipe 32 can adjust its length, so as to adjust the height between the bottom end of the conduit device 30 and the concrete pouring surface.

[0039] The automatic concrete chute device provided in this embodiment can adjust the height difference between the bottom end of the conduit device 30 and the concrete pouring surface through the telescopic pipe 32, which can effectively avoid the segregation of concrete caused by too high a falling height during concrete pouring. In addition, during traditional chute pouring, when the chute rotates, it is restricted by the rotation radius, and the discharging position cannot be continuously adjusted. Only several discrete pouring points can be set, and the concrete flows from the pouring points to the surrounding areas. The flow interception device 20 in this embodiment can drive the conduit device 30 to move along the chute 10, and can continuously adjust the discharging position of the conduit device 30, reduce the flowing distance of the concrete after falling, and avoid the segregation of the concrete caused by flowing, especially when the density of the steel bars is relatively large, the effect is more obvious.

[0040] In a specific embodiment, combined with Figures 2 to 5 As shown, the telescopic pipe 32 includes a first fixing ring 321, a second fixing ring 322, a telescopic device 323, and a corrugated pipe 324. The first fixing ring 321 and the second fixing ring 322 are spaced apart and fixedly connected to the corrugated pipe 324. Both ends of the telescopic device 323 are respectively connected to the first fixing ring and the second fixing ring, and can adjust the distance between the first fixing ring and the second fixing ring. For example, the telescopic device 323 can adopt a jack, an electric drive screw rod, etc. The telescopic device drives the first fixing ring and the second fixing ring to approach or separate, so that the corrugated pipe is stretched or compressed, thereby adjusting the actual length of the telescopic pipe 32, and further controlling the height between the bottom end of the conduit device 30 and the concrete pouring surface. Further, the conduit device 30 further includes a rigid pipe 31 located above the telescopic pipe 32 and a flexible pipe 33 located below the telescopic pipe 32. The rigid pipe 31, the telescopic pipe 32, and the flexible pipe 33 are sequentially communicated, and the top of the rigid pipe 31 communicates with the concrete storage bin 21.

[0041] In a specific embodiment, a rangefinder is provided on the intercepting device 20 or the conduit device 30, and the rangefinder is used to measure the height of the concrete pouring surface. The automatic concrete chute device further includes a processor, and a height difference threshold is preset in the processor. The processor can calculate the actual height difference between the discharge port of the conduit device 30 and the concrete pouring surface according to the measurement data of the rangefinder, and the processor can control the telescopic tube 32 of the conduit device 30 to expand and contract so that the actual height difference matches the preset height difference threshold.

[0042] In a specific embodiment, the rear end plate 22 on one side of the concrete storage bin 21 facing the lower part of the chute 10 can be opened and closed. When it is opened, the concrete moves downward along the chute 10.

[0043] In a specific embodiment, a sliding device is provided between the chute 10 and the intercepting device 20. The sliding device can adopt the form of a slide rail and a walking wheel, or the form of a gear and a toothed rail.

[0048] In a specific embodiment, a rangefinder is provided on the intercepting device 20 or the conduit device 30, and the automatic concrete chute device further includes a processor, and a height difference threshold is preset in the processor;

[0049] In Step 2, during the concrete pouring project, control the length of the telescopic tube 32 of the conduit device 30 so that the height difference between the bottom end of the conduit device 30 and the concrete pouring surface meets the requirements. Specifically:
