Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a detachable metal scoop device for structural columns installed at the upper opening of the structural column casting mold, which aims to provide a device that is easy to operate, structurally stable, and can effectively control the casting process. Background Technology

[0002] In construction engineering, the pouring of structural columns is a crucial step in ensuring the stability and safety of the building structure. The conventional method for pouring structural columns typically involves using timber or plywood to support the formwork, and setting up an inverted triangular pouring trough at the top of the column. After demolding, the concrete protruding from the trough is removed. This "pour first, then remove" method results in material waste and construction debris. The manual labor required for removal is significant, and prolonged work at height with hands suspended in the air poses safety hazards, especially for structural columns in cantilevered, open areas such as balconies.

[0003] Patent application CN201910722544.1 discloses a feeding funnel for a structural column casting mold. A lower support plate is fixed to the upper part of the mold opening, a rotating plate is hinged to the lower support plate, and two vertical side plates are fixed to both sides of the opening, with a gap between them. A stop bar passes through the through holes of the two vertical side plates. This invention improves the construction efficiency of structural columns and produces very good surface quality. This invention also provides a method for casting structural columns, including the following steps: constructing a structural column casting mold; constructing a feeding funnel at the upper opening of the mold; pouring concrete into the mold through the feeding funnel; after the concrete has set, pouring concrete again until the concrete reaches the upper part of the rotating plate; rotating the rotating plate to align the stop bar with another set of through holes in the vertical side plates; and fixing the rotating plate by inserting wedges into the gap between the stop bar and the rotating plate; after the concrete has set, removing the mold and the feeding funnel.

[0004] However, the aforementioned patented technology makes operating the rotating plate difficult, and the opening or closing of the rotating plate cannot be completed smoothly. Therefore, it is particularly important to develop a structural column pouring port device that is easy to operate and has good sealing performance. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable structural column metal scoop mouth device to solve the problems mentioned in the background art above:

[0006] (1) How to make the concrete of the structural column cast in one go without the need for later chiseling and easy to recycle the construction mold.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A detachable metal scoop opening device for structural columns is provided. This detachable metal scoop opening device for structural columns is installed at the upper opening of the structural column casting mold. The detachable metal scoop opening device for structural columns includes a rotating plate, a lower support plate, and two vertical side plates. The lower part of the lower support plate is fixedly connected to the upper part of the opening of the structural column casting mold. The lower end of the rotating plate is hinged to the lower support plate. The two vertical side plates are fixedly connected to the two edges of the opening of the structural column casting mold. The vertical side plates extend to the outside of the structural column casting mold. A gap is left between the two vertical side plates for the rotating plate to rotate.

[0009] This detachable structural column metal hopper mouth device also includes an opening and closing assembly, which includes a handle, a hinge seat, and a connecting rod. The hinge seat is fixedly connected to the side wall of the lower support plate and extends outward from the lower support plate. The middle part of the handle is hinged to the end of the hinge seat, the end of the handle is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the outer wall of the rotating plate.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, a guide rod is fixedly connected to the upper end of the outer wall of the rotating plate, with the two ends of the guide rod extending out from both sides of the rotating plate, and an arc-shaped hole that mates with the end of the guide rod is opened on the upper part of the vertical side plate.

[0012] Furthermore, it also includes a locking assembly, which includes a locking rod. The vertical side plate has a locking hole near the opening of the casting mold for the structural column, and the two ends of the locking rod can pass through the locking holes of the two vertical side plates respectively.

[0013] Furthermore, the locking assembly also includes a locking block, the beginning of which is fitted onto the side wall of the locking rod; when the rotating plate completely closes the opening of the structural column casting mold, the end of the locking block abuts against the outer side wall of the rotating plate.

[0014] Furthermore, the cross-sectional shape of the end of the locking block is a minor arc shape.

[0015] Furthermore, it also includes two side wing plates, which are fixedly connected to both sides of the upper opening of the structural column casting mold, and the vertical side plate is fixedly connected to the side wing plates.

[0016] After the concrete of the structural column is poured and compacted, the rotating plate is flipped to the top of the structural column using the opening and closing mechanism to close the pouring opening, cut off the concrete protruding from the wall, and then the rotating plate is fixed by the locking mechanism. Finally, the detachable structural column metal scoop device is removed, and the concrete pouring of the structural column is completed and curing begins. This detachable structural column metal scoop device is simple to use, easy to install, has a high reusability rate, requires no complicated training, is easily accepted by operators, and is conducive to promotion.

[0017] The beneficial effects of this detachable structural column metal scoop mouth device are:

[0018] (1) The detachable structural column metal scoop mouth device of this utility model realizes the rapid opening and closing of the mold opening through the design of the rotating plate, which is easy to operate and improves work efficiency.

[0019] (2) The cooperation between the guide rod and the arc-shaped hole ensures the smoothness and accuracy of the rotation of the rotating plate and avoids damage caused by improper operation.

[0020] (3) The design of the opening and closing components allows operators to easily control the opening and closing of the rotating plate, reducing labor intensity.

[0021] (4) The addition of the locking component further enhances the sealing performance of the device, effectively preventing concrete leakage and ensuring the quality of the pouring. Attached Figure Description

[0031] Please see Figures 1 to 4 .

[0032] A structural column casting mold 820 is erected at a predetermined location. The upper end of the structural column casting mold 820 extends to the position of the upper side beam 810. The detachable structural column metal scoop mouth device is set at the upper opening 500 of the structural column casting mold 820. The detachable structural column metal scoop mouth device includes a rotating plate 100, a lower support plate 200, two vertical side plates 300, two side wing plates 400, an opening and closing component, and a locking component.

[0033] The lower part of the lower support plate 200 is fixedly connected to the upper part of the opening 500 of the structural column casting mold 820. The lower end of the rotating plate 100 is hinged to the lower support plate 200 via a hinge 120. Two vertical side plates 300 are fixedly connected to the two side edges of the opening 500 of the structural column casting mold 820. The vertical side plates 300 extend outward from the structural column casting mold 820, and a gap is left between the two vertical side plates 300 for the rotating plate 100 to rotate only. Two side wing plates 400 are fixedly connected to both sides of the upper opening 500 of the structural column casting mold 820, and the vertical side plates 300 are fixedly connected to the side wing plates 400.
