Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a rotatable structural column casting funnel. Background Art

[0002] A structural column is a concrete structural column solidified within the masonry of a house, used to enhance the stability and strength of the building. Currently, the commonly used method for casting structural columns is: after supporting the structural column formwork, a casting opening is left, a bucket-shaped formwork is supported at the casting opening, and concrete is poured along the bucket-shaped formwork. After the concrete solidifies, the structural column formwork is removed. The bucket-shaped formwork used in this construction method is called a structural column dustpan. However, using a conventional dustpan requires removing the wedge-shaped concrete blocks formed at the dustpan, which lows construction efficiency and wastes construction materials and concrete.

[0003] In the prior art, the patent application number is 202420040041.2, and the patent name is a utility model patent for a structural column sealing formwork. A dustpan with a baffle is provided, but since the baffle is slidably arranged in the dustpan, there is a step between the baffle and the casting formwork. After the concrete in the structural column casting formwork is poured up, excess concrete wall with the thickness of the step will still be left on the surface of the structural column. This part of the concrete wall still needs to be chiseled out. Compared with the wedge-shaped concrete block, it only reduces the workload of chiseling, but cannot completely avoid it. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a reusable structural column casting funnel that does not require chiseling and maintains the flatness of the casting template.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a revolvable structural column casting funnel, which includes a casting template and a dustpan bucket;

[0006] A groove is provided on the top of the casting template, and one end of the dustpan is arranged in the groove;

[0007] The dustpan is a right-angled triangle structure with an opening at the top, including a vertical plate, an inclined plate and a side plate. The vertical plate is in contact with the inner wall of the casting template. A blanking opening is provided on the vertical plate. A rotating shaft is provided in the blanking opening. A baffle plate is fixed on the rotating shaft. The baffle plate can cover the lower half of the blanking opening and can be flipped upward to the upper half of the blanking opening under the drive of the rotating shaft. The thickness of the baffle plate is the same as that of the vertical plate.

[0008] A positioning mechanism is provided on the rotating shaft, and the positioning mechanism is used to fix the rotating shaft to prevent the rotating shaft from continuing to rotate after the baffle plate rotates to an appropriate position;

[0009] The dustpan is fixedly connected to the casting template via a fixing piece.

[0010] The beneficial effects of the above technical solution are: by optimizing the structure of the dustpan and the internal material blocking plate, the overall flatness of the structural column after forming is ensured, the vertical plate of the dustpan fits in with the inner wall of the casting template, and there is no step; the material blocking plate adopts a flipped form and the thickness of the material blocking plate is the same as the thickness of the vertical plate, further ensuring that the material blocking plate can be flush with the vertical plate and the casting template when blocking the material, avoiding the appearance of excess concrete residue after the structural column is formed, so that there is no need for additional chiseling operations, reducing labor costs and improving construction efficiency.

[0011] Furthermore, the blanking opening is a circular notch, and the baffle plate is a semicircular plate with the same diameter as the blanking opening.

[0012] Beneficial effects: the circular notch is easy to open, and the baffle plate has the same diameter as the blanking opening, ensuring that the baffle plate can completely cover the lower half of the blanking opening.

[0013] Furthermore, the rotating shaft is horizontally arranged in the center of the vertical plate, and the height of the rotating shaft is higher than the height of the top of the casting template.

[0014] Beneficial effect: The height of the rotating shaft is higher than the height of the top of the casting template, which prevents the concrete from being poured too high so that the baffle plate cannot form an effective seal, thereby ensuring the molding quality of the top of the structural column.

[0015] Furthermore, the fixing part includes a connecting bolt, threaded holes facing the outside of the casting template are provided on both sides of the groove, and through holes corresponding to the positions of the threaded holes are provided on the ear plate. The connecting bolts pass through the through holes and are threadedly connected to the threaded holes to fix the dustpan on the casting template.

[0016] Beneficial effect: the fixing piece connects the dustpan and the pouring template into a whole, which is more convenient to use.

[0017] Furthermore, the positioning mechanism includes a limit pin, the end of the rotating shaft passes through and extends out of the outside of the dustpan bucket, a positioning hole is opened at the end of the rotating shaft, and a pin hole is opened at the position corresponding to the positioning hole on the top of the casting template, and the limit pin passes through the positioning hole and is inserted into the pin hole.

[0018] Beneficial effect: the limit pin can fix the rotating shaft after the baffle plate is rotated to an appropriate position, preventing the rotating shaft from continuing to rotate and affecting the use effect of the dustpan bucket.

[0019] Furthermore, the positioning mechanism is provided in two groups, which are respectively located on both sides of the dustpan.

[0020] Beneficial effect: The rotating shaft is limited from both sides of the dustpan bucket, and when the baffle plate is subjected to force, it can ensure uniform force and a more stable structure. BRIEF DESCRIPTION OF THE DRAWINGS
