[0026] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] like Figure 1-8 As shown, a detachable wall column dustpan mouth concrete pouring device includes a triangular dustpan mouth 1, a dustpan mouth connection component, and a pouring mouth closing plate component; a pouring mouth 3 is opened on a wooden template 2, and the pouring mouth closing plate component is arranged on the wooden template 2 outside the pouring mouth 3; the triangular dustpan mouth 1 is connected to the wooden template 2 through the dustpan mouth connection component and is located outside the pouring mouth 3; the triangular dustpan mouth 1 is located outside the pouring mouth closing plate component. The triangular dustpan mouth 1 is made of metal.
[0029] like Figure 3 As shown, the pouring port closing plate assembly includes a slide plate 4 and two slide grooves 5, the two slide grooves 5 are respectively connected to the two sides of the pouring port 3, and the slide plate 4 is slidably connected between the two slide grooves 5. The slide plate 4 and the slide groove 5 are both made of metal. The size of the slide plate 4 is larger than the pouring port 3.
[0030] like Figure 6 As shown, a cutting head 6 is provided at the upper end of the side wall of the slide plate 4 close to the pouring port 3 .
[0031] Specifically, after the wall and column concrete are poured and compacted, the metal slide plate 4 fixed on the wooden formwork 2 is slid upward, the pouring port 3 is closed, the concrete protruding from the wall is cut off, and then the upper bolt 9 steel bar is taken out, and the metal dustpan mouth 1 is turned downward to recycle this part of the concrete.
[0032] Specifically, the chute 5 is welded and assembled by two steel plates with a width of 20mm / 30mm and a thickness of 4.5mm, and fixed on the 600×600mm plywood with self-tapping screws with a spacing of 40mm and a length of 25mm. To ensure that the metal slide plate 4 slides smoothly, a 1mm thick rubber strip (width 20mm, same as the steel plate at the bottom of the chute) can be placed between the chute and the template base when the metal slide is installed. The metal slide plate is 4mm thick and rolled into an L shape, which can slide up and down in the chute 5 to open or close the pouring port 3. The upper back of the metal slide plate 4 is welded with a steel plate (cut head 6) with the same width as the pouring port and the same thickness as the plywood, which is appropriately polished into an inclined surface and a blade shape to reduce the resistance when sliding upward and cutting the concrete.
[0033] like Figure 1 , 7 As shown, there are two groups of dustpan mouth connection components, which are respectively connected to the upper and lower ends of the triangular dustpan mouth 1; the dustpan mouth connection components include two latch hole plates 7, two latch tubes 8 and a latch 9; the two latch hole plates 7 are respectively connected to the two sides of the pouring mouth 3, and the two latch tubes 8 are respectively connected to the two sides of the triangular dustpan mouth 1. The latch 9 penetrates the latch tube 8 and the latch hole plate 7 to connect the triangular dustpan mouth 1 with the wooden template 2. The latch hole plate 7 is connected to the wooden template 2 by a plurality of screws 10. The latch 9 is a steel bar.
[0034] Specifically, after the post-cast wall column concrete pouring is completed, the metal triangular dustpan mouth 1 can be immediately used after cleaning, and repeated use can save costs.
[0035] Specifically, the metal triangular dustpan mouth 1 is rolled from a 4mm thick steel plate and is used for concrete pouring. After pouring, the dustpan mouth mold can be disassembled and removed to recycle the concrete protruding from the wall, and the dustpan mouth mold can be used in a turnover manner.
[0036] Specifically, the latch hole plate 7 is made of a steel pipe with an inner diameter of 10 mm, a wall thickness of 2 mm, and a length of 30 mm; the latch 9 is made of φ8 steel bars and is L-shaped.
[0037] Specifically, before pouring concrete, slide the metal slide plate 4 downward to open the pouring port 3 and prepare to start pouring concrete. Stop pouring until the concrete in the triangular dustpan port 1 is at least 30 mm higher than the bottom of the beam. Slide the metal slide plate 4 upward to close the pouring port 3 and cut off the protruding wall concrete. Nail the bottom of the slide plate 4 to temporarily fix the metal slide plate. Take out the upper latch 9, turn the triangular dustpan port 1 downward, and recover the concrete in the mold. Take out the lower latch 9, remove the triangular dustpan port 1, clean it and use it in a turnover manner.
[0038] The detachable wall column dustpan concrete pouring device solves the problems of concrete waste, labor input eliminated by traditional construction methods and construction waste generated; it also reduces the number of high-altitude operations and eliminates safety hazards.
[0039] It can be cast in one time without the need for later chiseling. The triangular dustpan mouth 1 construction mold is easy to turn over and can be reused to save costs, effectively solving the shortcomings of traditional construction methods.
