Description

Technical Field

[0001] This utility model relates to the field of structural column devices, and in particular to a device for eliminating the need for chiseling the funnel-shaped opening during the pouring of structural columns. Background Technology

[0002] Structural columns are common secondary construction components in building construction. They require reinforcement binding, formwork erection, and concrete pouring after the masonry work is completed. When pouring concrete for structural columns, since there is no space above, a flared section needs to be created on the top side of the column to facilitate construction. In conventional practice, wooden formwork is typically used for structural columns, and therefore, wooden formwork is also commonly used for the flared section. However, this method has the following disadvantages: the flared section concrete cannot be separated from the structural column, requiring secondary chiseling after formwork removal, resulting in material waste and increased labor costs.

[0003] While some new approaches exist, they still have limitations. For example, Chinese patent CN222501041U involves pushing a movable plate to seal the opening after concrete pouring, which cannot guarantee the precise volume and density of the concrete. Furthermore, the reinforcement method for the entire device is unclear. Another example is Chinese patent CN221502689U, where the rectangular baffle experiences excessive friction when pushed upwards through the concrete, making it difficult for workers to operate. Additionally, misalignment between the column formwork and the rectangular baffle requires secondary chiseling. Similarly, Chinese patent CN222478169U also suffers from misalignment between the column formwork and the rectangular baffle, excessive friction when pushing the sliding inclined plate upwards, and the hopper cannot be removed separately, increasing the device's turnover cost. Therefore, a chiseling-free device for pouring the bell-shaped opening of structural columns is needed to solve the problems of traditional methods requiring secondary chiseling and the inability to reuse the device. Utility Model Content

[0004] The purpose of this utility model is to provide a device for eliminating the need to remove the funnel-shaped opening during the casting of structural columns, thereby solving the existing technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A device for eliminating the need for chiseling when casting a structural column funnel includes a template, a funnel, and insert plates. The template has an opening in the upper middle part, and L-shaped folding plates are respectively provided on both sides of the opening. The insert plates are respectively inserted into the L-shaped folding plates on both sides. A connecting ear plate is connected to one side of the L-shaped folding plate. L-shaped grooves are provided on the upper part of both sides of the connecting ear plate, and the funnel is hung on the L-shaped grooves on both sides.

[0007] Furthermore, the template is provided with a U-shaped reinforcing rib on its outer side, and the opening is provided on the inner side of the U-shaped reinforcing rib.

[0008] Furthermore, the connecting ear plate is configured as a U-shaped structure, and the connecting ear plate is fixed to the L-shaped folding plate by welding.

[0009] Furthermore, the horn-shaped opening includes a rectangular plate and two triangular plates, which are respectively connected to both sides of the rectangular plate. Each of the two triangular plates is provided with a hanging nail, which is hung on an L-shaped groove. The rectangular plate is inclined, and one end of the rectangular plate rests on the bottom of the connecting ear plate.

[0010] Furthermore, an arc-shaped limiting rod is provided on the lower side of the bottom end of the rectangular plate. One end of the arc-shaped limiting rod is welded to the rectangular plate, and the other end of the arc-shaped limiting rod abuts against the template and the U-shaped reinforcing rib respectively.

[0011] Furthermore, the insert plate includes a sealing plate, a reinforcing end plate, and a handle. The reinforcing end plate is connected to the top of the sealing plate, the handle is connected to one side of the reinforcing end plate, and the two sides of the sealing plate are respectively inserted into the L-shaped groove.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0022] like Figure 1-4 As shown, a non-chiseling device for pouring a funnel-shaped opening in a structural column includes a template 1, a funnel-shaped opening 4, and insert plates 5. The template 1 has an opening 14 in its upper middle part. L-shaped folded plates 6 are respectively provided on both sides of the opening 14. The insert plates 5 are inserted into the L-shaped folded plates 6 on both sides of the opening 14. The L-shaped folded plates 6 on both sides of the opening 14 serve as grooves for the insert plates 5. A connecting ear plate 3 is connected to one side of the L-shaped folded plate 6. L-shaped grooves 15 are provided on the upper parts of both sides of the connecting ear plate 3. The funnel-shaped opening 4 is hung on both sides of the L-shaped grooves 15. The L-shaped grooves 15 facilitate the hanging of the funnel-shaped opening 4, which can be detached separately. In use, concrete enters through the funnel-shaped opening 4 to pour the structural column. After pouring, the insert plates 5 are inserted into the L-shaped folded plates 6, allowing the funnel-shaped opening 4 to be removed. The remaining concrete on the funnel-shaped opening 4 can be reused.

[0023] like Figure 2 As shown, the template 1 has a U-shaped reinforcing rib 2 on its outer side. The two sides of the U-shaped reinforcing rib 2 are inclined to enhance the stability of the template. The opening 14 is located on the inner side of the U-shaped reinforcing rib 2. The template 1 uses a standardized steel mold for easy reuse. The size of the template 1 should be larger than the structural column, preferably 340mm (width) × 210mm (height). The connecting ear plate 3 is set as a U-shaped structure, and the connecting ear plate 3 is fixed to the L-shaped folding plate 6 by welding. The L-shaped folding plate 6 forms an L-shaped bend. The L-shaped bend and L-shaped groove can also be changed to U-shaped, Z-shaped, or 7-shaped, that is, they can be replaced without affecting the function.

[0024] like Figure 3As shown, the flared opening 4 includes a rectangular plate 7 and two triangular plates 8. The two triangular plates 8 are respectively connected to both sides of the rectangular plate 7. Each of the two triangular plates 8 is provided with a hanging nail 9, which is hung on an L-shaped groove 15. The rectangular plate 7 is inclined, and one end of the rectangular plate 7 rests on the bottom of the connecting ear plate 3. By placing the rectangular plate 7 of the flared opening 4 on the bottom of the connecting ear plate 3 and hanging it on the L-shaped groove 15 via the hanging nails 9, the flared opening 4 and the connecting ear plate 3 are made into a detachable device, facilitating disassembly and reuse after pouring. An arc-shaped limiting rod 10 is provided on the lower side of the bottom end of the rectangular plate 7. One end of the arc-shaped limiting rod 10 is welded to the rectangular plate 7, and the other end of the arc-shaped limiting rod 10 abuts against the template 1 and the U-shaped reinforcing rib 2, respectively. The arc-shaped limiting rod 10 abuts against the template 1 and the U-shaped reinforcing rib 2 to support the flared opening and prevent it from tipping over due to excessive weight of the concrete. To fully address the issue of misalignment, an insert plate is inserted into the top opening to ensure it is flush with the formwork surface, effectively guaranteeing the flatness of the top of the structural column and achieving true chiseling-free construction. The insertion-isolation method eliminates the need for calculations of allowances and ensures concrete density, resulting in better concrete forming. Taking into account the actual frictional resistance, the insert plate is inserted from top to bottom for easier operation. The flared opening uses a hanging lug design and is rotatable, ensuring convenient operation even when there is concrete inside. The flared opening is detachable and reusable, reducing the cost of device manufacturing and use.

[0025] like Figure 4 As shown, the insert plate 5 includes a sealing plate 11, a reinforcing end plate 12, and a handle 13. The reinforcing end plate 12 is connected to the top of the sealing plate 11, and the handle 13 is connected to one side of the reinforcing end plate 12. The two sides of the sealing plate 11 are respectively inserted into the L-shaped groove 15. After the pouring is completed, the insert plate 5 is inserted into the L-shaped folding plate 6 to isolate the concrete at the flared end, and then the flared end and the concrete on it are reused.

[0026] The type, specifications, and length of all materials used in the flared-mouth no-chiseling device of this utility model can be replaced without affecting its function. In addition to pressing the square timber for reinforcement, the device can also be reinforced with tie rods through openings. Besides welding, the various components can also be connected using bolts or other methods.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
