Description

Technical Field

[0001] This utility model relates to the technical field of unloading devices, and in particular to a hollow slab beam double unloading hopper device. Background Technology

[0002] In the prefabrication of hollow slab beams, high-density foam is typically used as the core mold due to its advantages such as light weight and easy demolding. However, traditional casting processes using a single discharge hopper for concrete pouring present the following problems:

[0003] Core mold misalignment problem: Due to the light weight of the foam core mold, the impact force and lateral extrusion force of the concrete on one side can easily cause the core mold to shift, resulting in uneven wall thickness of the slab and beam, which affects the structural quality.

[0004] Uneven pouring: Single-point unloading can cause concrete to accumulate on one side of the core mold, resulting in deviations in the thickness of the protective layer, and even problems such as local exposed reinforcement or excessively thick concrete.

[0005] Low construction efficiency: Traditional hoppers cannot achieve simultaneous pouring at both discharge ports, requiring repeated adjustments to the pouring position, which affects the construction progress.

[0006] Currently, some projects are trying to use steel core molds or add counterweights to the core molds, but steel molds are difficult to assemble and disassemble, and the counterweight method increases construction costs.

[0007] Therefore, there is an urgent need for a hopper device that can simultaneously and evenly pour material to fundamentally solve the problem of core mold misalignment. Utility Model Content

[0042] Example 1

[0043] Reference Figure 1 The first embodiment of this utility model provides a hollow slab beam double discharge port hopper device, as detailed below:

[0044] The device mainly includes:

[0045] Concrete receiving unit 100: It consists of a main hopper 101 and a hopper partition plate 102. The partition plate is vertically set inside the main hopper 101, dividing it into two independent partition cavities to ensure that the concrete can be evenly distributed.

[0046] Dual discharge control unit 200: includes a first discharge port 201 and a second discharge port 202 arranged symmetrically. Each discharge port is equipped with an independent first discharge valve 201a and a second discharge valve 202a. The discharge valves have exposed operating handles for controlling the flow of concrete.

[0047] Synchronous operation unit 300: It consists of a detachable synchronous unloading device 301. Its linkage structure can simultaneously connect the operating handles of two unloading valves to realize the synchronous opening and closing of the two unloading ports.

[0048] The working principle is as follows:

[0049] Synchronous unloading mode: Connect both ends of the synchronous unloading device 301 to the operating handle of the double unloading valve, rotate the linkage structure to open the two unloading valves synchronously, and the concrete flows into the hollow slab beam formwork from both sides at the same time, avoiding the core mold deviation caused by unilateral impact.

[0050] Single unloading mode: Remove the synchronous unloading device 301 and operate any unloading valve individually to achieve unloading on one side, adapting to different construction needs.

[0051] In this embodiment, simultaneous pouring with dual discharge ports is adopted to avoid unilateral impact of concrete, ensure the stability of the core mold, and improve the uniformity of the beam wall thickness; the simultaneous / single discharge mode can be flexibly switched to adapt to different construction scenarios; the structure is simple, the operation is convenient, and the construction efficiency is high.

[0052] Example 2

[0053] Reference Figure 2 , 3 4. This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that, based on embodiment 1, the hopper partitioning structure is further optimized, as detailed below:

[0054] The outer edge of the partition plate 102 of the hopper is adapted to the inner wall structure of the main hopper 101 and forms a sealed connection to ensure that the two partition cavities are completely independent and to prevent concrete crossflow.

[0055] The bottom sealing structure (not shown in the figure) is adapted to the internal structure of the main hopper 101. A rubber sealing strip can be used to fit tightly against the inner wall of the main hopper 101 to prevent slurry leakage.

[0056] The cavities in each zone have the same volume, ensuring that the amount of concrete poured on both sides is consistent and improving the uniformity of the pouring.

[0057] In this embodiment, the completely independent zoning design avoids uneven concrete mixing; the sealing structure prevents grout leakage and improves construction quality; and the consistent amount of concrete on both sides further reduces the risk of core mold misalignment.

[0058] Example 3

[0059] Reference Figure 2 , 3 4 is the third embodiment of this utility model. The difference between this embodiment and the first embodiment is that the structure of the unloading valve is optimized based on the first embodiment to improve the ease of operation.

[0060] The first discharge valve 201a and the second discharge valve 202a in this scheme are rotary valves with valve plates arranged inside the discharge port and controlled by the operating handle.

[0061] The exposed length of the handle is adapted to the operating stroke of the synchronous unloading device 301, ensuring that the linkage structure can be smoothly connected.

[0062] The valve has an opening angle of 90°. It is fully open when rotated to the horizontal position and fully closed when rotated to the vertical position, making operation intuitive.

[0063] In this embodiment: the valve has a simple structure, opens and closes quickly, improving construction efficiency; the handle length is optimized to ensure stable operation of the synchronous unloading device 301; the valve opening and closing status is clear, avoiding misoperation.

[0064] Example 4

[0065] Reference Figure 2 , 3 4 is the fourth embodiment of this utility model. This embodiment differs from the first embodiment in that, based on embodiment 1, the structure of the synchronous unloading device 301 is optimized to improve operational stability, as detailed below:

[0066] The rigid connecting rod body 301b is made of stainless steel, and has a first sleeve part 301a and a second sleeve part 301c at both ends to form a transition fit with the operating handle of the unloading valve to ensure a stable connection.

[0067] Anti-slip texture (not shown in the figure) is applied to the surface of the rigid connecting rod body 301b to enhance friction during manual operation and prevent slippage.

[0068] The quick-release design features a flexible snap-fit ​​structure for easy and rapid installation and disassembly.

[0069] In this embodiment: the rigid connecting rod body 301b is made of stainless steel to ensure durability and adapt to high-intensity construction environments; the anti-slip texture design improves operating comfort and reduces worker fatigue; the quick-assembly and disassembly structure facilitates switching between synchronous / single unloading modes and improves construction flexibility.

[0070] The hollow slab beam double unloading hopper device provided in this solution effectively solves the core mold misalignment problem caused by traditional single unloading hopper casting through the synchronous casting technology of double unloading hoppers. Examples 1-4 have made corresponding technical optimizations to the hopper zoning, unloading valve and synchronous unloading device in the prior art, so that the device has significant advantages in terms of construction quality, ease of operation and adaptability.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
