Description

Technical Field

[0001] The present application belongs to the technical field of building construction, and specifically relates to a concrete pouring device. Background Art

[0002] Most construction projects are large-scale and tight in schedule. They require large concrete volumes and need to be poured continuously. Using concrete pumps for pouring is not only costly, but also easy to cause pipe blockage due to factors such as large coarse aggregate size, poor workability, and concrete stratification, which interrupts concrete construction and affects the quality of concrete construction. Using open concrete chutes is not only low-cost and fast in pouring, but also has no risk of pipe blockage, making it more economical and applicable.

[0003] However, the existing traditional concrete chutes still have the following shortcomings in actual engineering applications: first, most of the existing chutes are bulky, inconvenient to carry, and difficult to transport; second, the commonly used concrete chutes have only one pouring port with a small coverage area, and the concrete is easily concentrated and accumulated somewhere in the formwork, which increases the workload of manual leveling of the concrete and is not conducive to the compaction and vibration of the concrete in the later stage; third, the pouring of concrete with great depth and large span often has a large slope and a large height difference, which is easy to cause segregation due to the excessively fast sliding speed of the concrete, affecting the construction quality. Utility Model Content

[0004] The purpose of the present application is to provide a concrete pouring device, which solves the problem that traditional concrete chutes are not suitable for large-depth and large-span concrete pouring.

[0007] Furthermore, the hopper is an inverted quadrangular pyramid structure, the down pipe and the vertical chute are cylindrical tubes, and the inclined chute is an arc-shaped cross-section.

DETAILED DESCRIPTION

[0025] The present application is further described below in conjunction with specific embodiments and drawings.

[0026] refer to Figure 1 to Figure 4 As shown, a concrete pouring device includes a hopper 1, a feed pipe 2, a vertical chute 3, an inclined chute 4, a fixed placement component, an upper connection component and a lower connection component. The device can be used for pouring concrete for a manually dug pile body, and can also be used for cylindrical full concrete structures such as a pool, a silo, and a bridge pier.

[0027] The hopper 1 is an inverted quadrangular pyramid structure, and is used for collecting and loading concrete. A discharge pipe 2 is provided at the bottom of the hopper 1, and the discharge pipe 2 is a cylindrical pipe. Concrete enters from the upper opening of the hopper 1, and the concrete entering the hopper 1 falls out from the discharge pipe 2 under the action of gravity.

[0028] The hopper 1 is provided with a fixed installation component, which is used to achieve stable installation of the hopper 1, ensuring that the hopper 1 does not shake or deflect during concrete pouring, and ensuring the stability, continuity and reliability of the overall pouring. The fixed installation component can be in various forms.

[0029] For example, the fixed placement assembly includes a lifting ring 5, which is welded on the left and right sides of the upper end of the hopper 1. When there is no building body as a foundation near the hopper 1, the hopper 1 can be directly lifted by a tower crane or a crane to keep the placement of the hopper 1 stable. At the same time, the lifting ring 5 is also used for other lifting operations of the hopper 1.

[0030] For another example, the fixed placement assembly includes a hook 6, a joist 7 and a support rod 8. The hook 6 is welded on the left and right sides of the hopper 1. The hook 6 is an L-shaped structure or a bent hook structure, and the hook portion of the hook 6 is kept facing downward. The joist 7 is fixed on the main body of the building. The joist 7 is a cantilever structure or a force-bearing structure at both ends. At least two joists 7 are arranged. The support rod 8 is arranged between two adjacent joists 7. The support rod 8 is welded or connected to the joist 7 through a pipe fastener. At least two support rods 8 are also arranged.

[0031] The hooks 6 on both sides are respectively hung on the supporting rods 8 on both sides, so as to ensure that the hopper 1 is stably placed on the supporting rods 8. Since the hopper 1 is also located between the two supporting beams 7, the side of the hopper 1 is in contact with the supporting beams 7 and the supporting rods 8, and the supporting beams 7 and the supporting rods 8 also limit the hopper 1, further improving the stability of the hopper 1.

[0032] The down pipe 2 is inserted into the upper end of the vertical pipe 3, which is a cylindrical pipe, so that the concrete dropped from the hopper 1 enters the vertical pipe 3. Two sealing rings 12 are provided on the outer side of the down pipe 2 to cooperate with the vertical pipe 3 to prevent the slurry from leaking out from the gap between the two pipes and ensure the sealing performance.

[0033] A vertically adjustable upper connecting component is provided between the hopper 1 and the vertical chute 3. The upper connecting component is used to connect the hopper 1 and the vertical chute 3 as a whole. At the same time, the upper connecting component can be adjusted vertically to fine-tune the distance between the hopper 1 and the vertical chute 3 to ensure that the two pipes are accurately aligned and not prone to leakage.

[0034] The upper connection assembly includes an upper pull ring 9, a lower pull ring 10 and a pull rope 11. The upper pull ring 9 is welded on the left and right sides of the hopper 1, and the lower pull ring 10 is welded on the left and right sides of the vertical chute 3. A pull rope 11 is arranged between the upper pull ring 9 and the lower pull ring 10. Tightening the pull rope 11 will pull the hopper 1 and the vertical chute 3 closer and ensure that the lower pipe 2 is inserted into the vertical chute 3.

[0035] The lower end of the vertical chute 3 is opposite to the upper end of the inclined chute 4, and the inclined chute 4 has an arc-shaped cross-section, so that the concrete falling from the vertical chute 3 falls onto the inclined chute 4 and continues to slide along the inclined chute 4 at a lower speed until it falls from the lower end of the inclined chute 4 to the casting position.

[0036] A horizontally rotating lower connecting component is provided between the vertical chute 3 and the inclined chute 4. The lower connecting component is used to connect the vertical chute 3 and the inclined chute 4 as a whole. At the same time, the lower connecting component can rotate horizontally, so that the inclined chute 4 can change its direction to meet the needs of large-scale casting.

[0037] The lower connecting assembly includes a connecting cap 13, a rotating ring 14 and a connecting rod 15. The connecting cap 13 is welded to the inclined chute 4 as a whole, and is covered on the upper end of the inclined chute 4 to prevent the falling concrete from splashing there. The vertical chute 3 is passed through the connecting cap 13, and the connecting cap 13 can rotate horizontally with the inclined chute 4 relative to the vertical chute 3. The rotating ring 14 can adopt a bearing, which is fixed on the vertical chute 3, but cannot move axially. The rotating ring 14 is connected to the connecting cap 13 through a connecting rod 15, and the connecting rods 15 on both sides pull the connecting cap 13 to ensure the stability of the vertical position of the inclined chute 4.

[0038] Connecting hooks 17 are welded on both sides of the connecting cap 13, and connecting heads 16 are welded on both sides of the rotating ring 14. The connecting heads 16 are connected to the connecting hooks 17 through connecting rods 15, and the connecting rods 15 on both sides are used to complete the lower connection. The connecting rod 15 is a length-adjustable structure, such as a threaded sleeve rod, and the distance between the vertical chute 3 and the inclined chute 4 is adjusted by the telescopic movement of the connecting rod 15 to avoid concrete blockage caused by a small distance.

[0039] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In the scheme of this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.

[0040] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
