Description

Technical Field

[0001] This utility model belongs to the field of concrete construction technology, specifically relating to a concrete unloading protection device. Background Technology

[0002] In the concrete pouring of full-section box culverts, especially in the pouring of sidewalls and roof slabs, pumping or mechanical unloading methods are commonly used to improve construction efficiency. However, in actual operation, when concrete is unloaded to the sidewalls through pipes or robotic arms, some concrete often spills onto the roof slab. Since the sidewall pouring process is relatively time-consuming, spilled concrete on the roof slab, if not treated promptly, is prone to forming cold joints due to moisture evaporation. These cold joints not only affect the overall quality of the poured concrete but also negatively impact the appearance, significantly reducing the aesthetics and durability of the box culvert structure. Therefore, a device is needed to reduce concrete spillage on the roof surface during pouring, thereby effectively preventing cold joints on the roof slab and improving the overall construction quality of the box culvert structure.

[0005] Preferably, a limiting hole is provided at the bottom of the baffle, and a limiting groove is provided on the corresponding base, so that both ends of the support rod can be inserted into the limiting hole and the limiting groove respectively for limiting.

[0006] Preferably, the length of the limiting groove is greater than the length of the support rod, one end of the support rod is movable, and the other end is hinged in the limiting groove, so that the support rod can be stored in the limiting groove.

[0007] Preferably, the storage component includes a protrusion fixed to the side of the base, with a slot on the protrusion; a groove is provided on the corresponding baffle, the groove penetrating the top and side surfaces of the baffle; a rotating seat is connected inside the groove, one end of a limiting rod is rotatably connected to the rotating seat, and the other end extends out of the groove and is threaded; the end of the limiting rod can be locked into the slot for fixation.

[0008] Preferably, the end of the limiting rod is connected to the first nut by a thread, and the first nut presses against the protrusion to realize the storage of the unloading device.

[0009] Preferably, it also includes a lightweight replacement plate, which includes a top plate and a side plate. A first through hole is provided on the top plate, through which a limiting rod can pass and be fixed by a first nut. After the top plate is fixed, the side plate fits against the baffle surface to achieve slope protection.

[0010] Preferably, the top of the baffle is also connected to a handle for easy carrying, with a slot reserved for the handle on the top plate of the lightweight replacement plate.

[0011] Preferably, it also includes a fixing component, which includes a stud, the end of which is connected to a clamping plate; a second through hole is opened on the base, one end of the stud passes through the second through hole to clamp the clamping plate at the bottom of the steel cage, and the other end is connected to the base by a second nut.

[0012] Preferably, the fixing component also includes an L-shaped hook plate, one end of which hooks onto the outer template of the side wall, and the other end of which has a third through hole.

[0013] Preferably, the baffle and the base are connected by a hinge.

[0014] Compared with existing technologies, the above technical solution has the following advantages or beneficial effects:

[0015] 1. This utility model uses a support rod to support the baffle and the stand to form a stable triangular structure, which protects the top surface during the full-section box culvert concrete pouring process and prevents concrete from splashing onto the top surface of the box culvert and causing cold joints. At the same time, when the device is finished, the support rod can be stored in the limiting groove of the stand and stored in the storage component, which facilitates the transportation of the device.

[0016] 2. This utility model achieves storage and fixation of the lightweight replacement plate through a rotating limiting rod and a first nut. When the limiting rod rotates to the vertical position, the lightweight replacement plate is passed through the limiting rod and screwed into the first nut to achieve fixation. When the limiting rod rotates to the horizontal position, the end is inserted into the slot and pressed by the first nut to achieve storage. This not only facilitates storage but also prevents excessive concrete from splashing onto the baffle surface, thus increasing the weight of the device and making it inconvenient to transport. This problem can be solved by replacing the lightweight replacement plate.

[0017] 3. This utility model achieves rapid connection and fixation between the device and the box culvert template through a fixing component. It has a simple structure, is easy to construct, and can improve construction efficiency. Attached Figure Description

[0030] Example 1:

[0031] Please see Figures 1-5 To address the issue of concrete spillage onto the top slab 42 during the pouring of concrete for the side walls and top slab 42 in a full-section box culvert, where pumping or mechanical unloading methods are used, resulting in cold joints on the top slab 42 due to the long pouring time of the side walls, which negatively impacts the quality and appearance of the poured concrete, a concrete unloading protection device was designed. This device includes a baffle 1 with a hinged base 2 connected to it. In this embodiment, the baffle 1 and base 2 are connected by a hinge 8. The base 2 is positioned at the top of the slope. A support rod 3 connects the baffle 1 and base 2, forming a stable triangular structure with the baffle 1 and base 2 to ensure sufficient strength to withstand the impact from the concrete. A storage component is also connected between the baffle 1 and base 2 for convenient storage.

[0032] In this embodiment, a limiting hole 12 is provided at the bottom of the baffle 1, and a limiting groove 21 is provided on the corresponding base 2. Both ends of the support rod 3 can be inserted into the limiting hole 12 and the limiting groove 21 respectively for limiting. The length of the limiting groove 21 is greater than the length of the support rod 3. One end of the support rod 3 is movable, and the other end is hinged in the limiting groove 21. The support rod 3 can be stored in the limiting groove 21, improving the portability of this device.

[0033] Example 2:

[0034] Based on Embodiment 1, this embodiment proposes a storage component that can be used for both folding and mounting a lightweight replacement plate 4. It includes a protrusion 22 fixed to the side of the base 2, with a slot 23 on the protrusion 22. A corresponding groove 11 is formed on the baffle 1, penetrating the top and side surfaces of the baffle 1. A rotating seat 13 is connected within the groove 11. One end of a limiting rod 5 is rotatably connected to the rotating seat 13, while the other end extends out of the groove 11 and is threaded 51. The end of the limiting rod 5 can be locked into the slot 23 for fixation. The end of the limiting rod 5 is connected to a first nut 6 via the thread 51. The first nut 6 presses against the protrusion 22 to achieve storage of the unloading device. Simultaneously, the support rod 3 can also be pressed into the limiting groove 21 for easy carrying.

[0035] In addition, considering that concrete may accumulate on the baffle 1 and is difficult to clean after it hardens, the protective device will become increasingly heavy and its portability will be greatly reduced with long-term use. Therefore, based on the above-mentioned storage device, this embodiment also proposes a lightweight replacement plate 4 to cooperate with it. The lightweight replacement plate 4 can be in the form of a membrane or a plate, and can be used for one time and discarded after one pouring. The lightweight replacement plate 4 includes a top plate 42 and a side plate 41. A first through hole 43 is opened on the top plate 42, and the limiting rod 5 can pass through the first through hole 43 and be fixed by the first nut 6. After the top plate 42 is fixed, the side plate 41 fits against the baffle 1 to achieve slope protection.

[0036] Finally, to improve portability, a convenient carrying handle 7 is also connected to the top of the baffle 1, corresponding to the slot 44 reserved for the handle 7 on the top plate 42 of the lightweight replacement plate 4.

[0037] How to use:

[0038] First, in its stowed state, place the device on the reinforcing cage on top of the box culvert formwork, with the opening facing away from the cast-in-place side wall. Loosen the first nut 6, lift the baffle 1, and rotate the support rod 3 to pull it out of the limiting groove 21. Insert the end of the support rod 3 into the limiting hole 12. Then, rotate the limiting rod 5 to change it from a horizontal to a vertical position. Align the first through hole 43 on the lightweight replacement plate 4 with the limiting rod 5 and insert it, so that the side plate 41 fits against the surface of the baffle 1. Finally, tighten the first nut 6 to complete the assembly. Disassembly only requires reversing the operation to stow away from the construction site.

[0039] Example 3:

[0040] See Figures 1-8 The casting formwork for the box culvert mainly includes the outer formwork 91 of the side walls and the inner formwork 92 of the top wall. There is a steel cage 93 between the inner formwork 92 of the top wall and the outer formwork 91 of the side walls for casting the side walls. The inner formwork 92 of the top wall is equipped with a steel cage 93 for casting the top wall. The construction sequence is to cast the side walls first and then the top wall. Therefore, it is necessary to fix this device to the steel cage 93 on the inner formwork 92 of the top wall. Based on this, this embodiment, based on embodiment two, also proposes a fixing component 10. The fixing component 10 includes a stud 101. The end of the stud 101 is connected to a clamping plate 102. The length of the clamping plate 102 is greater than the distance between the left and right steel bars, and the width is less than the distance between the left and right steel bars. A second through hole 24 is opened on the corresponding base 2. One end of the stud 101 passes through the second through hole 24 so that the clamping plate 102 is clamped at the bottom of the steel cage 93, and the other end is connected to the base 2 through a second nut 105.

[0041] The fixing component 10 also includes an L-shaped hook plate 103. One end of the L-shaped hook plate 103 hooks onto the outer template 91 of the side wall, and the other end of the L-shaped hook plate 103 has a third through hole 104. After the top of the limiting rod 5 passes through the third through hole 104 and is fixed, the first nut 6 is tightened to fix it.

[0042] When in use, simply support the device, insert the stud 101 into the second through hole 24, rotate it so that the length of the clamping plate 102 is clamped between the two steel bars of the steel cage 93, and tighten the second nut 105 to fix the device; then fix the L-shaped hook plate 103 on the limiting rod 5, and fix the device by hooking the top of the side wall outer formwork 91 with the L-shaped hook plate 103.

[0043] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
