Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an auxiliary pouring tool for exterior wall structural columns. Background Technology

[0002] Structural columns are reinforced concrete columns installed within the walls of multi-story brick-concrete buildings. They connect with the ring beams of each floor, forming a spatial frame structure that resists bending and shear, enhancing the overall integrity and stability of the building and serving as a crucial measure to prevent collapse. Traditionally, during the concrete pouring process for structural columns, formwork is erected outside the reinforcing steel bars, with a grouting inlet and funnel at the top. Concrete is then poured into the formwork using grouting equipment or manually through the funnel. After pouring and formwork removal, funnel-shaped concrete bulges remain at the grouting inlet, requiring subsequent chiseling and cleaning. This process is not only time-consuming and labor-intensive but also makes it difficult to ensure the integrity and flatness of the wall surface.

[0003] To address the issue of removing protrusions after casting, existing technologies employ inserting sealing plates before the concrete initially sets to separate the grout inside the structural column from excess grout in the funnel. For example, Chinese patent "202323457529.X" discloses a structural column casting structure that uses a leveling mechanism to press down a sealing shovel plate, making the front end of the structural column flush with the formwork, thus preventing concrete protrusions and ensuring the smoothness of the column's outer surface. However, while this method separates the grout in different areas, the concrete grout in the funnel cannot be quickly and effectively discharged, remaining in the casting funnel. This not only wastes materials but also makes demolding difficult, affecting the final quality of the structural column.

[0004] Therefore, it is necessary to study an auxiliary pouring tool for external wall structural columns. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an auxiliary pouring tool for external wall structural columns, which effectively solves the problems of the inconvenience of discharging the remaining slurry in the existing pouring funnel, the inability to recycle excess concrete, resulting in material waste, and the difficulty of demolding, which easily damages the integrity of the concrete column inside the structural column.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an auxiliary pouring tool for exterior wall structural columns, comprising a bottom mold, a hopper, and a sliding plate. A rope wheel is provided above the bottom mold, and a hopper that gradually slopes inward is provided in the middle of the bottom mold. Outer seats are symmetrically provided on the left and right sides of the bottom mold, forming a discharge channel between the hopper and the bottom mold. Slide grooves are symmetrically provided on the inner sidewalls of the outer seats. The left and right sides of the sliding plate are fitted and locked in the slide grooves, and the front side of the sliding plate is flush with the front end of the bottom mold. The top of the sliding plate is fixedly connected to a steel wire rope on the rope wheel. Driving the rope wheel to rotate can make the sliding plate slide up and down in the discharge channel to block or open the discharge channel.

[0007] Furthermore, an outer seat is fixed on the bottom mold below the hopper, and the left and right sides of the hopper are fixed to the outer seat by bolts, and the sliding plate is slidably engaged in the groove of the outer seat.

[0008] Furthermore, hooks are symmetrically provided on the outer seat, and storage boxes are hung on the hooks. The top of the storage boxes is connected to the discharge channel.

[0009] Furthermore, the storage box has symmetrical hook grooves on its left and right sides, and hooks are symmetrically provided on the outer seat to hang the storage box on the hooks on the outer seat, so that the remaining slurry in the hopper flows down into the storage box from the discharge channel.

[0010] Furthermore, the slide plate is provided with sliders at both ends, and the top of the sliders is provided with a hanging ring. The output end of the steel wire rope on the rope wheel extends vertically downward and is connected to the hanging ring, so as to use the rotation of the rope wheel to drive the slide plate to move up and down through the steel wire rope.

[0011] The beneficial effects of the above technical solution are as follows: The auxiliary pouring tool for exterior wall structural columns provided by this utility model avoids the formation of concrete protrusions at the grouting port in traditional methods through the dynamic control of the sliding plate, reducing material waste. It also ensures that the structural column is flush with the exterior wall, improving the flatness and overall aesthetics of the wall surface. Furthermore, excess grout can be recycled, further conserving resources. This solution has a simple structure, is easy to operate, and can significantly improve construction efficiency and the forming quality of the structural column.

[0012] This new technology employs a dynamic sealing technique using a sliding plate. A rope pulley drives the sliding plate to rise and fall within a vertical chute. During pouring, the sliding plate is lowered to open the grouting channel; upon completion, the sliding plate is raised to close the grouting port, simultaneously triggering the opening of the discharge channel. This eliminates the concrete protrusion problem inherent in traditional processes. The connection between the discharge channel at the bottom of the hopper and the storage box allows for the automatic discharge and centralized collection of uncured material, effectively preventing waste.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0020] Example 1: This example aims to provide an auxiliary pouring tool for external wall structural columns. It is mainly used to achieve precise sealing of the grouting port and recovery of residual material in the funnel during the pouring process of structural columns. It is proposed to address the problems of concrete protrusions that are easy to produce in traditional pouring methods, which require subsequent chiseling, and the inconvenience of recovering residual grout in the funnel, resulting in material waste.

[0021] like Figure 1-4 As shown, the auxiliary pouring tool for the external wall structural column provided in this embodiment includes a bottom mold 2, a hopper 3, and a sliding plate 5. The bottom mold 2 is used to fix on the wall surface of the external wall 1 on the left and right sides of the grouting space of the structural column to be poured. A rope wheel 4 is fixed above the bottom mold 2, and an outer seat 6 is symmetrically fixed on the bottom mold 2. The left and right sides of the hopper 3 are fixed to the outer seat by bolts. The outer seat is evenly fixed with main ribs (not shown in the figure) along the vertical direction by tie bolts to form the external mold support of the structural column. The hopper 3 is open on the side facing the bottom mold 2 and at the top. The hopper 3 gradually tilts and shrinks inward towards the bottom mold 2 from top to bottom. A grouting port 15 communicating with the inner cavity of the hopper 3 is provided on the side wall of the bottom mold 2. Grout is injected into the hopper 3 using grouting equipment. The grout in the hopper 3 enters the interior of the structural column pouring space from the grouting port 15.

[0022] like Figure 2 and 3As shown, a discharge channel 8 is formed between the hopper 3 and the bottom mold 2. Specifically, the bottom of the hopper 3 is provided with an opening, and there is a gap between the bottom of the hopper 3 and the bottom mold. This gap forms a discharge channel 8 between the hopper 3 and the bottom mold 2. On the inner sidewall of the outer seat 6 on the left and right sides of the discharge channel 8, there are vertical grooves 7. The slide plate 5 is located in the discharge channel 8, and its left and right sides are adapted to slide and be fitted in the grooves 7. The front side of the slide plate 5 is flush with the front end of the bottom mold 2, and the overall width of the slide plate 5 is greater than the size of the grouting port 15 of the structural column to ensure that the grouting port 15 of the structural column is covered, so that the main body of the structural column is flush with the outer wall 1.

[0023] Furthermore, sliders are provided at both ends of the slide plate 5. The slider structure is adapted to the shape of the slide groove 7 and is slidably installed in the slide groove. A hanging ring is provided at the top of the slider. The position of the hanging ring is on the same vertical line as the position of the rope wheel 4. The output end of the steel wire rope on the rope wheel extends vertically downward and is connected to the hanging ring, driving the rope wheel 4 to rotate forward and backward, thereby driving the slide plate 5 to move up and down through the steel wire rope. In this embodiment, two sets of rope wheels 4 are provided on the bottom mold 2. Each set of rope wheels 4 is provided with a rotating handwheel, and the two sets of rope wheels 4 are respectively fixedly connected to the left and right sides of the slide plate 5 to ensure the stability of the slide plate 5 during the up and down movement.

[0024] In this embodiment, the on-site construction personnel drive the rope wheel 4 to rotate by rotating the rope wheel 4, which in turn pulls the slide plate 5 up and down within the discharge channel 8 via the wire rope. Figure 3 As shown, when the slide plate 5 slides to match the discharge interval, grout is injected into the hopper 3 through the grouting equipment, so that the grout flows from the grouting port 15 of the structural column into the pouring space of the structural column. After the grouting is completed, the rope wheel 4 is driven to rotate again, driving the slide plate 5 to move upward until it completely covers the outside of the grouting port 15. At this time, the slide plate 5 is located above the discharge channel 8, the discharge channel 8 is opened, and the grout in the hopper 3 is discharged downward along the discharge channel 8 to the storage box for recycling, avoiding waste. It should be noted that the rope wheel described in this embodiment can be a fixed pulley structure, with the wire rope wrapped around the rear end of the fixed pulley and wound on the miniature winch. To reduce costs, it can also be a small hand-cranked bidirectional self-locking winch to facilitate the lifting and lowering of the slide plate.

[0025] Furthermore, such as Figure 4 As shown, in order to facilitate the guidance and recycling of the slurry in the hopper 3, hooks 9 are symmetrically provided on the outer seat 6. A storage box 10 is hung on the hooks 9. Specifically, hook grooves 11 are symmetrically opened on the left and right sides of the storage box to hang the storage box on the hooks on the outer seat. At the same time, the top of the storage box is connected to the discharge channel, so that the remaining slurry in the hopper 3 flows down from the discharge channel 8 into the storage box 10, which facilitates the recycling of excess concrete slurry.

[0026] Working principle description: The auxiliary pouring tool for the external wall 1 structural column provided in this embodiment is used by fixing the auxiliary device outside the pouring space of the structural column. Then, ensure that the sliding plate 5 is inserted into the groove of the outer seat 6 and is in the lowest position. At this time, the sliding plate 5 is located below the discharge channel 8. During the pouring operation, turn the handwheel of the rope wheel 4 to pull up the sliding plate 5, so that the sliding plate moves upward to the discharge channel 8 and is blocked. The hopper 3 is connected to the grouting port 15. Start the grouting equipment to inject concrete into the hopper 3. The grout enters the structural column cavity through the grouting port 15. Observe the pouring height of the structural column. Stop grouting when the concrete is close to the top of the grouting port 15. Then, install the storage box below the hopper and continue to turn the handwheel of the rope wheel 4 to lift the sliding plate 5. After the sliding plate 5 moves up, it completely blocks the grouting port 15. The discharge channel 8 is then opened. The remaining concrete in the hopper 3 flows downward along the discharge channel at the bottom of the inclined hopper. The grout flows into the storage box 10, completing the automatic recovery of the residual grout. The funnel and sliding plate can be removed with the formwork after the structural column is formed.

[0027] The auxiliary pouring tool for exterior wall structural columns provided in this embodiment aims to solve problems such as residual protrusions at the grouting port, material waste, and inconvenience in recycling residual materials during the traditional structural column pouring process. This utility model, through the cooperation of a sliding plate and a discharge channel, achieves precise injection of grout and discharge of excess grout, thereby improving construction efficiency and molding quality. It also avoids the formation of concrete protrusions at the grouting port as in traditional methods, reducing material waste, and ensures that the structural column is flush with the exterior wall, improving wall surface flatness and overall aesthetics.

[0028] Example 2, based on Example 1, involves a sliding engagement between the sliding plate and the outer seat via a groove. However, since the funnel is filled with concrete slurry during casting, to prevent the concrete slurry from flowing into the groove and affecting the vertical movement of the sliding plate, the sliding plate and the outer seat can also have a convex-concave fit structure in practical applications, such as... Figure 5 As shown, a lifting ring 12 is provided at the top of the slide to connect to a rope pulley via a steel wire rope. This design in this embodiment, with its concave-convex mating structure, reduces the risk of concrete slurry seeping into the slide, effectively reducing jamming and improving construction efficiency.

[0029] The above-described embodiments of this utility model do not constitute a limitation on the scope of protection of this utility model. The basic concept of this utility model is to set a sliding plate outside the grouting port of the structural column. When the sliding plate is placed inside the discharge channel, the discharge channel is blocked, allowing the grout in the hopper to enter the pouring space of the structural column. When the sliding plate covers the outside of the grouting port, the discharge channel is opened, allowing excess grout in the hopper to be discharged from the discharge channel. This not only makes the surface of the formed structural column flush but also allows for the recycling of excess concrete grout in the hopper, avoiding waste. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
