[0002] In the construction of infill walls for building buildings, the common construction process for structural columns involves using timber and plywood to support the formwork, and setting an inverted triangular pouring trough at the top of the column for concrete pouring. After the formwork is removed, the concrete protruding from the wall surface at the trough needs to be removed. However, the formwork for the trough takes a long time to prepare, and the "pour first, then remove" approach results in material waste and construction debris. The manual labor required for removal is also significant, and prolonged work at height with hands suspended in the air poses certain safety hazards.

[0003] Therefore, it is necessary to propose a scoop-mouth structure for the concrete pouring of secondary structural columns that does not require subsequent chiseling and allows for convenient turnover of construction molds, in order to solve the above problems. Utility Model Content

The two sides of the sliding plate 3 are respectively slidably engaged with the two vertical sliding grooves 4, and are guided and limited by the two vertical sliding grooves 4.

[0035] In this embodiment, both vertical grooves 4 are located between two right-angled triangular baffles 2-1.

[0036] In actual use, one right-angled side of the right-angled triangular baffle 2-1 is placed close to the base 1, and the other right-angled side of the right-angled triangular baffle 2-1 is perpendicular to the base 1.

[0037] In practice, the vertical slide 4 is a steel plate set on the base 1, and the vertical slide 4 is fixed to the base 1 by multiple self-tapping screws.

[0038] In this embodiment, the winnowing basket mold 2 is detachably mounted on the base 1 via a top pin 5 and a bottom pin 7. A top sleeve 6 for inserting the top pin 5 is provided on the top of each side of the winnowing basket mold 2, and a bottom sleeve 8 for inserting the bottom pin 7 is provided on the bottom of each side of the winnowing basket mold 2.

[0039] The base 1 is provided with two top sleeves 6 for inserting top pins 5 and two bottom sleeves 8 for inserting bottom pins 7.

[0040] In actual use, the two top sleeves 6 on the hopper mouth mold 2 are arranged coaxially, the two bottom sleeves 8 on the hopper mouth mold 2 are arranged coaxially, the two top sleeves 6 on the base 1 are arranged coaxially, the two bottom sleeves 8 on the base 1 are arranged coaxially, and the top pin 5 and the bottom pin 7 are both L-shaped pins.

[0041] It should be noted that when installing the winnowing basket mold 2, the winnowing basket mold 2 should be placed tightly against the base 1, and the two top sleeves 6 on the winnowing basket mold 2 should be coaxially arranged with the two top sleeves 6 on the base 1, and the two bottom sleeves 8 on the winnowing basket mold 2 should be coaxially arranged with the two bottom sleeves 8 on the base 1. Then, one end of the top pin 5 should be passed through the four top sleeves 6 in sequence, and one end of the bottom pin 7 should be passed through the four bottom sleeves 8 in sequence to complete the installation of the winnowing basket mold 2. When disassembling the winnowing basket mold 2, simply remove the top pins 5 and the bottom pins 7 to remove the winnowing basket mold 2.
