Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a dustpan mouth structure. Background Art

[0002] Currently, the construction industry and civil engineering projects are vigorously promoting commercial concrete. During the construction process, concrete holes are often opened in the concrete walls to connect auxiliary scaffolding. These holes need to be repaired promptly after construction is complete. Under existing technical conditions, large red support forms and dustpan openings are usually required for post-concrete pouring to repair these holes. However, this repair method uses some formwork that is not reusable, consumes a lot of materials, and suffers from poor support effects.

[0003] Patent publication number CN 219931623 discloses a chiseling-free dustpan-mouth pouring device suitable for post-poured concrete, comprising a fixed plate, a dustpan mouth and a movable baffle. The fixed plate is provided with a first opening suitable for passing concrete, the dustpan mouth is arranged on the outer surface of the fixed plate, and the discharge port of the dustpan mouth is connected to the opening. The movable baffle is slidably fitted on the inner surface of the fixed plate, and the movable baffle is suitable for opening or closing the first opening.

[0004] The use of the above-mentioned dustpan-shaped pouring device can realize the reuse of concrete hole repair tools and reduce consumables. However, in actual use, the concrete holes are horizontal holes. After the concrete is poured, the concrete cannot be tamped and it is difficult to pour densely, which affects the durability of the structure and the pouring quality of the concrete at the concrete hole. Utility Model Content

[0005] The utility model provides a dustpan mouth structure for repairing a concrete hole, which solves the problem in the prior art that the concrete poured in the concrete hole cannot be tamped and the concrete pouring is not dense.

[0006] The technical solution of the present utility model is achieved as follows:

[0007] A dustpan opening structure for repairing a concrete hole includes a dustpan opening, an oblique support mechanism disposed on the outside of the dustpan opening, and a compaction mechanism disposed on the inside of the dustpan opening. During concrete hole repair, the dustpan opening is positioned relative to the hole, and the oblique support mechanism supports and secures the dustpan opening, ensuring a stable position during concrete pouring. After pouring, the compaction mechanism compacts the concrete within the concrete hole, ensuring dense concrete pouring, thereby ensuring concrete pouring quality and improving the durability of the concrete wall.

[0008] The compacting mechanism includes a pressing plate, the lower side of which is movably connected to the lower edge of the inner side of the dustpan opening, and the two sides of which are in contact with the side walls of the dustpan opening. A clamping member is provided on the outer side of the pressing plate for limiting the position of the pressing plate. After the concrete is poured, the concrete is compacted by the movable pressing plate to ensure that the concrete fills the hole tightly. After the concrete is compacted, the clamping member is used to limit the position of the pressing plate, so that the pressing plate continues to apply pressure to the poured concrete, ensuring that the concrete in the hole is poured tightly and the quality of the hole repair is guaranteed.

[0009] The upper end of the clamping member is movably connected to the pressing plate, and the lower side of the clamping member is provided with a plurality of latching teeth arranged side by side, which are engaged with the upper edge of the dustpan opening. After the pressing plate compacts the concrete, the latching teeth are engaged with the upper edge of the dustpan opening to limit the pressing plate.

[0010] A handle is provided on the upper side of the clamping member, which facilitates the staff to adjust the clamping member and adjust the connection state between the clamping member and the dustpan opening.

[0011] The dustpan mouth comprises an inclined plate, both sides of which are connected with side plates, and baffles are provided on the outer sides of the two side plates and the lower side of the inclined plate, and the baffles are fitted with the concrete wall.

[0012] The lower edge of the inclined plate is hinged to the lower edge of the pressing plate. The pressing plate can press the concrete in the dustpan opening into the hole and compact the concrete.

[0013] The two sides of the pressing plate are fitted with the side plates. During the movement of the pressing plate, concrete is prevented from seeping out from between the two sides of the pressing plate and the side plates, and concrete is prevented from flowing to the outside of the pressing plate.

[0014] The diagonal support mechanism includes a telescopic rod, the upper end of the telescopic rod is hinged to the outer side of the inclined plate, and the lower end of the telescopic rod is engaged with the ground. The telescopic rod can be extended and retracted to make the dustpan mouth structure suitable for concrete holes of different heights, thereby enhancing the structural applicability.

[0015] The telescopic rod includes a telescopic inner rod and a telescopic tube, which are threadedly connected to each other. Rotating the telescopic inner rod can adjust the relative position of the telescopic inner rod and the telescopic tube, thereby adjusting the length of the telescopic rod. After the length of the telescopic rod is adjusted, the length of the telescopic rod is fixed by the self-locking function of the thread.

[0016] The lower end of the telescopic inner rod is provided with an anti-skid structure. The anti-skid structure ensures that the lower end of the telescopic inner rod is in stable contact with the ground, thereby ensuring the stability of the telescopic rod in supporting the dustpan opening.

[0017] The beneficial effects of the utility model are as follows: after the concrete is poured, the concrete in the dustpan mouth is pressed into the hole through the compacting mechanism, so that the concrete in the hole is densely filled, thereby ensuring the quality of the hole repair; at the same time, when pouring concrete, there is no need to completely fill the dustpan mouth with concrete, and the concrete is pushed into the hole by the pressing plate, leaving only a small amount of concrete protruding from the wall surface, thereby effectively reducing the amount of concrete used and saving costs.

[0018] The diagonal bracing mechanism adopts a telescopic rod. By adjusting the length of the telescopic rod, the dustpan mouth structure can be adapted to the repair of concrete holes at different heights, effectively improving the applicability of the structure. In addition, the anti-slip structure provided at the lower end of the telescopic inner rod can ensure the stability of the contact between the diagonal bracing mechanism and the ground, thereby ensuring the stability of the telescopic rod's support for the dustpan mouth.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1, as Figure 1 、 Figure 2 、 Figure 4 As shown, a dustpan mouth structure for repairing a concrete hole includes a dustpan mouth 1, a diagonal bracing mechanism 4 disposed on the outside of the dustpan mouth 1, and a compacting mechanism disposed on the inside of the dustpan mouth 1. When the structure is in use, the dustpan mouth 1 is aligned with a hole 6 in a concrete wall 5, with the diagonal bracing mechanism 4 resting on the ground. The diagonal bracing mechanism 4 then provides support for the dustpan mouth 1, ensuring its stability during concrete pouring. After the concrete is poured, the compacting mechanism compacts the concrete within the hole 6, ensuring a dense concrete pour, thereby ensuring the quality of the concrete pouring and improving the durability of the concrete wall.

[0027] Furthermore, the compacting mechanism includes a pressing plate 2, the lower side of which is movably connected to the lower edge of the inner side of the dustpan opening 1, and the two sides of the pressing plate 2 are in contact with the side walls of the dustpan opening 1. A clamping member 3 for limiting the position of the pressing plate 2 is provided on the outer side of the pressing plate 2. After the concrete is poured, the concrete is compacted by the movable pressing plate 2 to ensure that the concrete fills the hole tightly. After the concrete is compacted, the clamping member 3 is used to limit the position of the pressing plate 2, so that the pressing plate 2 continues to apply pressure to the poured concrete, ensuring that the concrete in the hole is poured tightly and the quality of the hole repair is guaranteed.

[0028] In addition, when the dustpan mouth structure is actually used, it is only necessary to fill 1 / 2 to 2 / 3 of the concrete into the dustpan mouth 1, and then push the concrete into the hole through the pressure plate 2, leaving only a small amount of concrete protruding from the wall, effectively reducing the amount of concrete used, saving costs, and reducing the subsequent workload of removing the protruding wall concrete.

[0029] Furthermore, the upper end of the clamping member 3 is movably connected to the pressing plate 2. A plurality of side-by-side arranged latching teeth 31 are provided on the lower side of the clamping member 3. The latching teeth 31 latch with the upper edge of the dustpan opening 1. The clamping member 3 can swing up and down relative to the pressing plate 2. When the clamping member 3 is lifted upward, the latching teeth 31 can be separated from the upper edge of the dustpan opening 1, eliminating the position restriction on the pressing plate 2. After the pressing plate 2 compacts the concrete, the latching teeth 3 latch with the upper edge of the dustpan opening 1, and the latching teeth 31 retain the pressing plate 2.

[0030] Further, a handle 32 is provided on the upper side of the clamping member 3. The handle 32 facilitates the staff to adjust the clamping member 3 and adjust the connection state of the clamping member 3 and the dustpan mouth 1.

[0031] Example 2, based on Example 1, a concrete hole repair dustpan mouth structure, such as Figure 3As shown, the dustpan opening 1 includes an inclined plate 13, with side plates 12 connected to both sides of the inclined plate 13. Baffles 11 are provided on the outer sides of the two side plates 12 and the lower side of the inclined plate 13. The baffles 11 are in contact with the concrete wall 5. The contact between the baffles 11 and the concrete wall 5 can prevent concrete from flowing out of the gap between the baffles 11 and the concrete wall 5 during pouring. In this embodiment, the baffles 11 are provided with anti-skid rubber pads. The anti-skid rubber pads ensure the sealing between the baffles 11 and the concrete wall 5 and prevent the baffles 11 from sliding on the concrete wall 5, ensuring that the dustpan opening 1 remains stable relative to the concrete wall 5 during use.

[0032] Furthermore, the lower edge of the inclined plate 13 is hingedly connected to the lower edge of the pressing plate 2. The pressing plate 2 moves to press the concrete in the dustpan opening 1 into the opening 6, compacting the concrete. The sides of the pressing plate 2 are in contact with the side panels 12. During the movement of the pressing plate 2, concrete is prevented from leaking between the sides of the pressing plate 2 and the side panels 12, preventing the concrete from flowing outside the pressing plate 2.

[0033] Example 3, based on Example 1 or Example 2, provides a dustpan opening structure for repairing a concrete hole. The diagonal bracing mechanism 4 includes a telescopic rod, the upper end of which is hinged to the outer side of the inclined plate 13, and the lower end of which engages the ground. The telescopic rod can be extended and retracted to adapt the dustpan opening structure to concrete holes of different heights, thereby enhancing the structural adaptability.

[0034] Furthermore, the telescopic rod includes a telescopic inner rod and a telescopic tube, which are threadedly connected to each other. Rotating the telescopic inner rod can adjust the relative position of the telescopic inner rod and the telescopic tube, thereby adjusting the length of the telescopic rod. After the length of the telescopic rod is adjusted, the length of the telescopic rod is fixed by the self-locking function of the thread.

[0035] Furthermore, the lower end of the telescopic inner rod is provided with an anti-skid structure. In this embodiment, the anti-skid structure is a conical head, which ensures the stability of the contact between the lower end of the telescopic inner rod and the ground, thereby ensuring the support stability of the telescopic rod on the dustpan opening.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
