Description

Technical Field

[0001] This utility model relates to the field of concrete construction, specifically to a construction device for a large-volume concrete pouring chute. Background Technology

[0002] When pouring large volumes of concrete, pump trucks cannot be used due to site limitations. To ensure the continuity and speed of concrete pouring, a chute and feeder system is typically used. Specifically, concrete is first transported to the pouring point via a chute, and then discharged and poured via a feeder. To control the pouring sequence of large volumes of concrete, the traditional method involves installing pouring bends on the chute. After pouring in one direction, workers use a tower crane to rotate the bend to the other direction for further pouring. However, the bends are too heavy for workers to move, and while tower cranes can be used, controlling the force and direction is difficult. Furthermore, existing chutes have other problems, such as cumbersome installation, high labor costs, poor stability, and inconvenience for pouring directly beneath the chute. Utility Model Content

[0003] The purpose of this utility model is to provide a construction device for large-volume concrete pouring chutes, which not only facilitates the control of various pouring directions of large-volume concrete, but also makes the entire chute construction simple, convenient and low-cost.

[0038] Please refer to Figures 1 to 8 This application provides a construction device for a large-volume concrete pouring chute, including a main chute 1 and a support frame 2. The main chute 1 is arranged at an inclination. There are several support frames 2, which are spaced apart and supported below the main chute 1. Several vertical chutes 3 are connected at intervals to the lower side of the main chute 1. Each vertical chute 3 is provided with a terminal hopper 4 at its lower end. Branch chutes 41 are respectively provided at the bottom and sides of the terminal hopper 4. A discharge control plate 42 is rotatably arranged in the terminal hopper 4 at a position corresponding to the inlet end of each branch chute 41. The discharge control plate 42 is used to control the opening and closing of the corresponding branch chute 41.

[0039] This application connects several vertical chutes 3 at intervals to the lower side of the main chute 1. Each vertical chute 3 is equipped with a terminal hopper 4 at its lower end, and branch chutes 41 are respectively set at the bottom and side of the terminal hopper 4. At the same time, a discharge control plate 42 is rotatably installed in the terminal hopper 4 at a position corresponding to the inlet end of each branch chute 41. During construction, the corresponding vertical chute 3 is selected according to the concrete pouring area, and the opening and closing of the corresponding branch chute 41 is controlled by the discharge control plate 42. This allows for convenient and quick control of the pouring direction of large volume concrete, and avoids areas where pouring is inconvenient.

[0040] According to some embodiments of this application, the discharge control plate 42 is rotatably connected to the inner wall of the end hopper 4 via a hinge 43. Since the discharge control plate 42 is made of 500*500*4mm steel plate, by using the hinge 43 to rotatably connect the discharge control plate 42, and with the hinge 43 connected to the upper side of the discharge control plate 42 (i.e., the side near the top of the end hopper 4), the discharge control plate 42 can be flipped upwards around the hinge 43 to open the discharge port on that side, allowing concrete to flow into the corresponding branch chute 41. When it is necessary to close the discharge port on that side, the discharge control plate 42 will automatically fit against the inner wall of the end hopper 4 after being lowered, thereby blocking the discharge port.

[0041] According to some embodiments of this application, the discharge control plate 42 is provided with a rubber layer on the side that connects to the inlet end of the branch chute 41. By providing the rubber layer, after the discharge control plate 42 is closed, the rubber layer can fit against the inner wall of the end hopper 4, which helps to improve the sealing effect after the discharge control plate 42 is closed.

[0042] According to some embodiments of this application, a hook 44 is provided on the side of the discharge control plate 42 opposite to the end hopper 4 which is rotatably connected to it. The hook 44 is used to hook onto the top of the end hopper 4 after the discharge control plate 42 is flipped open. By providing the hook 44 on the discharge control plate 42, the hook 44 can be hooked onto the top of the end hopper 4 after the discharge control plate 42 is flipped up, thereby keeping the discharge port on that side open.

[0043] According to some embodiments of this application, the end hopper 4 is funnel-shaped, having four sides and a bottom. The end hopper 4 has openings on three of its sides and on its bottom, with corresponding branch chutes 41 welded to them. Specifically, the end hopper 4 is made of 7mm steel plate, with an upper opening of 1000×1000mm and a lower opening of 600×600mm. The lower opening is funnel-shaped, with openings on three sides and a hole at the bottom, the diameter of which is 377mm. The discharge control plates 42 on the three sides can be flipped upwards, while the discharge control plate 42 at the bottom can be flipped to the side without an opening.

[0044] According to some embodiments of this application, a transfer hopper 5 is provided on the main chute 1 at a position corresponding to each vertical chute 3. The transfer hopper 5 has interfaces on two opposite side walls and communicates with the front and rear sections of the main chute 1. The transfer hopper 5 has a discharge hole at the bottom and is equipped with an openable baffle plate 51. The material discharged from the discharge hole enters the vertical chute 3. With the above solution, when it is necessary for material to flow through a certain vertical chute 3, the baffle plate 51 at the bottom of the transfer hopper 5 can be opened, and the concrete flowing down from the main chute 1 can enter the vertical chute 3 through the discharge hole at the bottom of the transfer hopper 5.

[0045] According to some embodiments of this application, a cluster hopper 6 is provided at the top of the vertical chute 3. The cluster hopper 6 is funnel-shaped, and its lower end can be inserted into the top of the vertical chute 3. Specifically, the top of the cluster hopper 6 is an open structure, allowing concrete flowing out of the discharge hole at the bottom of the conversion hopper 5 to fall directly into the cluster hopper 6. A connector is provided at the bottom of the cluster hopper 6. The outer diameter of the connector is slightly smaller than the inner diameter of the vertical chute 3, so that the connector at the lower end of the cluster hopper 6 can be directly inserted into the top of the vertical chute 3, thereby achieving communication between the cluster hopper 6 and the vertical chute 3.

[0046] According to some embodiments of this application, a discharge chute 9 is provided at the high end of the main chute 1, and the bottom of the discharge chute 9 is formed by a slope, so that after the concrete mixer truck discharges the material into the discharge chute 9, the concrete can flow into the main chute 1 quickly and completely.

[0047] According to some embodiments of this application, the vertical chute 3 is located in the support frame 2, the top of the vertical chute 3 is connected to the bundled hopper 6, and the bottom of the vertical chute 3 is connected to the end hopper 4. Since the end hopper 4 is also located in the support frame 2, the end hopper 4 can be fixedly connected to the support frame 2 when the chute is erected.

[0048] During construction, concrete enters the main chute 1 through the discharge chute 9 and flows down automatically. When discharge from a vertical chute 3 is required, the baffle plate 51 in the corresponding conversion hopper 5 at the top of the vertical chute 3 is opened. Concrete in the main chute 1 flows from the bottom of the conversion hopper 5 into the cluster hopper 6, and then sequentially into the vertical chute 3 and the end hopper 4. Then, depending on the pouring area, the discharge control plate 42 in a certain direction of the end hopper 4 can be opened, and the concrete can then be discharged from the corresponding branch chute 41. It should be noted that a branch chute 8 (not shown in detail in the figure) can be installed at the end of the branch chute 41.

[0049] According to some embodiments of this application, the slope of the main chute 1 is controlled between 1:3 and 1:4. The slope of the main chute 1 is crucial; if the slope is too large, the concrete flows too quickly, easily causing segregation; if the slope is too small, the concrete flows too slowly, failing to realize the advantages of rapid chute pouring, and may even lead to localized concrete accumulation and impaired flow. Based on construction experience, the above-mentioned slope is more suitable.

[0050] According to some embodiments of this application, the support frame 2 includes a plurality of tower crane standard sections 21 connected in sequence, and the end hopper 4 is fixed inside the tower crane standard section 21. Specifically, the tower crane standard section 21 has dimensions of 1630×1630×2800mm, is made of Q235B, and the connection between adjacent tower crane standard sections 21 is the same as that of existing tower cranes.

[0051] When the tower crane standard section 21 is installed on the top of the bottom slab reinforcement, the bottom support and the raft slab reinforcement bracket must be welded and fixed first, depending on the specific layout location. For areas requiring denser reinforcement, the reinforcement should be denser first, and then the tower crane standard section 21 should be welded and connected to the support. At the top of the tower crane standard section 21, I-beam columns 22 and crossbeams 23 are installed according to the slope of the main chute 1. The columns 22 are made of 16# I-beams, and the crossbeams 23 are made of 8# channel steel. Together, they form the top structure of the support frame 2.

[0052] According to some embodiments of this application, the support frame 2 is provided with multiple guy ropes 7 on its side. Specifically, the multiple guy ropes 7 can be symmetrically arranged on the components on both sides of the support frame 2, with one end of the guy rope 7 connected to the support frame 2 and the other end connected to the bottom plate reinforcement. By providing guy ropes 7, the overturning resistance of the support frame 2 can be improved.

[0053] This application uses multiple tower crane standard sections 21 to form a support frame 2 to support the main chute 1, and uses multiple guy ropes 7 to stabilize it. This method not only makes the chute erection simple and convenient, reducing the amount of manual scaffolding erection and dismantling, but also has low construction cost and good chute support stability.

[0054] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
