Description

Technical Field

[0001] This utility model relates to the field of building technology, and more specifically, to a concrete pouring funnel for structural columns. Background Technology

[0002] Structural columns, also known as reinforcing columns, are reinforced concrete columns installed in the walls of multi-story brick-concrete structures to enhance the overall integrity and stability of the building. These columns connect to the ring beams on each floor, forming a spatial frame capable of resisting bending and shear, and are an effective measure to prevent building collapse. Structural columns are typically placed at the four corners of exterior walls, at the intersection of transverse and longitudinal walls in staggered floor areas, on both sides of large openings, and at the intersection of interior and exterior walls in large rooms. Furthermore, the requirements for structural column placement vary depending on the number of stories and the seismic intensity. The minimum cross-sectional size of a structural column is 240mm × 180mm, with 412φ vertical reinforcement commonly used, and stirrup spacing not exceeding 250mm. As the seismic intensity and number of stories increase, the cross-section and reinforcement grade of structural columns at the four corners of the building can be appropriately increased.

[0003] The lifting-type concrete pouring funnel disclosed in application number CN202320912729.0 is an increasingly mature technology. This utility model discloses a lifting-type concrete pouring funnel, including a base, a column, a square groove, a movable plate, a pouring funnel, rollers, a pull rope, and a motor. The column is screw-mounted above the base and is designed close to the base. A square groove is fitted onto the column, allowing it to move up and down vertically along the column. A movable plate, screw-mounted, is located on one side of the square groove, extending away from the base. The pouring funnel is mounted on the movable plate. Rollers are located at the top of the column. One end of the pull rope passes through the rollers and is connected to the movable plate; the other end is connected to a rotating shaft. The rotating shaft is connected to the motor via a coupling. The motor is screw-mounted to the base and is located away from the column. Fixing rods are installed at the four corners of the base. This utility model has a reasonable design; the motor and pull rope can pull the movable plate up and down, thereby changing the height of the pouring funnel.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist:

[0005] However, the production challenge of conventional structural columns is that concrete needs to be injected into the wall gaps to form a cylindrical column and placed vertically. The batches of structural column concrete to be produced are columnar, hence the name structural column. However, this type of cylindrical concrete inevitably involves mixing concrete materials with sand and gravel before being transferred to a concrete pouring machine and poured into a pouring funnel. Due to varying construction progress, the distance between the funnel and the structural column concrete needs to be constantly adjusted according to the pouring progress. Continuing construction operations are also required at the top of the already shaped structural column. Since the height is variable, conventional pouring funnels naturally do not meet production requirements. Furthermore, the concrete pouring funnel itself needs to transfer the processed concrete material and move up and down to gradually build up into a cylindrical column shape, which limits construction and makes it difficult to improve the construction efficiency of subsequent structural column concrete pouring. Utility Model Content

[0006] The purpose of this utility model is to provide a concrete pouring funnel for structural columns, in order to solve the production problem of conventional structural columns mentioned in the background art. This problem is that concrete needs to be injected into the gaps in the wall to form a column shape and placed vertically. The batches of structural column concrete to be produced are column-shaped, hence the name structural column. However, this type of column-shaped concrete inevitably involves mixing concrete materials with sand and gravel, and then transferring it to a concrete pouring machine. When it is poured into the pouring funnel, due to different construction progress, it is necessary to continuously change the interval between the funnel and the structural column concrete according to the pouring progress, and to continue construction operations on the top of the structural column that has already been shaped in the early stage.

[0007] This utility model embodiment provides a concrete pouring funnel for structural columns, including a support mechanism. The support mechanism includes a concave bracket supported by the ground. A placement frame is symmetrically installed on the top of the concave bracket. A connecting rod is horizontally installed on the side wall of the placement frame. An outer frame bracket is installed on the side wall of the connecting rod. A hopper is installed in the middle of the outer frame bracket. A material trough is opened at the top of the hopper. A surrounding rod is installed around the four corners of the concave bracket with connecting buckles. A connecting upright is vertically installed at the top center of the surrounding rod. An upper frame is provided at the top of the connecting upright.

[0008] As a preferred embodiment of this utility model: the bottom of the hopper is provided with a discharge mechanism.

[0009] The discharge mechanism includes hinges installed on both sides of the bottom of the hopper, and hopper covers are respectively hinged to both sides of the bottom of the hinges.

[0010] As a preferred embodiment of this utility model: a closed door is installed at the bottom of the hopper cover, a drive roller is provided in the middle of the hopper cover, a transmission rod is provided in the middle of the drive roller, a linkage actuating plate is provided in the middle of the transmission rod, and a pneumatic cylinder is installed at one end of the actuating plate.

[0011] As a preferred embodiment of this utility model: the cylinder body extension end of the pneumatic cylinder is connected to the linkage plate for transmission, and a vibration excitation mechanism is installed on the side of the hopper cover.

[0012] As a preferred embodiment of the present invention: the vibration mechanism includes a vibration base installed on the side wall of the hopper cover, and a plurality of vibrators are installed on the surface of the vibration base. The output end of the vibrator is set to vibrate with the surface of the hopper through the vibration base.

[0013] As a preferred embodiment of the present invention: a casting mechanism is installed on the side wall of the concave bracket, the casting mechanism includes a square frame installed on the side wall of the concave bracket, an upper top plate is provided at the top center of the square frame, and a transmission roller is installed at the top center of the upper top plate.

[0014] As a preferred embodiment of this utility model: a transmission base is installed at the top of the transmission roller shaft, a support rod is installed at the top of the transmission base, a bearing frame is hinged to the top of the support rod via the scheduling roller shaft, and an I-shaped bracket is installed at the top of the bearing frame.

[0015] As a preferred embodiment of this utility model: a telescopic bracket is connected to the top center of the I-shaped bracket, and a shaping mechanism is installed at the end of the telescopic bracket. The shaping mechanism includes an upper sliding ring installed on the side wall of the telescopic bracket. A plurality of fastening holes are sequentially opened on the top surface of the upper sliding ring. A lifting sliding rod is installed at the top of each of the plurality of fastening holes, and a lower sliding ring is sleeved at the bottom of the lifting sliding rod.

[0016] As a preferred embodiment of this utility model: the bottom of the lower sliding ring is supported by the ground, the top of the upper sliding ring is equipped with a conical cover, the top of the conical cover is provided with a feeding opening, the top of the feeding opening is connected to a conduit, and the other end of the conduit is connected to the bottom position of the hopper cover via a material pump.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1) The concave bracket and placement frame are used as the support for the hopper body to share the weight of the overall hopper. The hopper cover is triggered by the pneumatic cylinder to open the sealing door, ensuring uniform discharge of concrete from the hopper, avoiding manual feeding, speeding up the feeding efficiency, and preventing hopper blockage. Combined with the vibrator and vibrating base, vibration is generated to accelerate the transfer of concrete materials, reduce the pressure of manually making and transporting structural column concrete, and uniformly transport the produced concrete raw materials to the location of the structural column under construction, completing the work connection between different processes and improving construction efficiency.

[0019] 2) The use of guide pipes and conical seat covers facilitates the slow, layer-by-layer feeding of the concrete raw materials for the structural columns. When construction is required, the height range of the upper sliding ring can be changed to dampen and fix it at a certain height. The fastening openings allow for easy up-and-down sliding along the positions of multiple lifting sliding rods, facilitating pouring. This addresses the issue that in practical work, the concrete for structural columns needs to have its pouring height adjusted due to differences in the construction period. This improves the adaptability of the constructed concrete for structural columns, gradually forming the uniformity of the structural columns themselves and preventing tilting or misalignment during unloading and pouring.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example

[0032] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a concrete pouring funnel for structural columns, including a support mechanism 1. The support mechanism 1 includes a concave bracket 11 that supports the ground. A placement frame 12 is symmetrically installed on the top of the concave bracket 11. A connecting rod 13 is horizontally installed on the side wall of the placement frame 12. An outer frame bracket 14 is installed on the side wall of the connecting rod 13. A hopper 15 is installed in the middle of the outer frame bracket 14. A material trough 16 is opened at the top of the hopper 15. A connecting buckle 17 is installed at each of the four corners of the concave bracket 11. A surrounding rod 18 is installed around the middle of the top of the surrounding rod 18. A connecting rod 19 is vertically installed at the top middle of the connecting rod 19. An upper frame 191 is provided at the top of the connecting rod 19.

[0033] In this embodiment: the bottom of the hopper 15 is provided with a discharge mechanism 2.

[0034] The discharge mechanism 2 includes hinges 21 installed on both sides of the bottom of the hopper 15, and hopper covers 22 are respectively hinged to both sides of the bottom of the hinges 21.

[0035] By using the hinge 21 and the hopper cover 22, the hopper cover 22 is opened to discharge or closed at the connection of the hinge 21, so as to prevent the discharge speed from being too fast and exceeding the speed of material unloading, piling and solidifying in the casting funnel.

[0036] In this embodiment: a closed door 23 is installed at the bottom of the hopper cover 22, a drive roller 24 is provided in the middle of the hopper cover 22, a transmission rod 25 is provided in the middle of the drive roller 24, a linkage actuating plate 26 is provided in the middle of the transmission rod 25, and a pneumatic cylinder 27 is installed at one end of the actuating plate 26.

[0037] The pneumatic cylinder 27 is used. After the cylinder body is energized, the transmission rod 25 drives the opening and closing power of the hopper cover 22, which pushes the closing door 23 to discharge and close the material.

[0038] In this embodiment: the cylinder extension end of the pneumatic cylinder 27 is connected to the linkage plate 28 for transmission, and the side of the hopper cover 22 is equipped with a vibration mechanism 3.

[0039] The vibration mechanism 3 used accelerates the discharge efficiency and avoids stagnation and blockage at the discharge point.

[0040] In this embodiment: the vibration mechanism 3 includes a vibration base 31 installed on the side wall of the hopper cover 22. Several vibrators 32 are installed on the surface of the vibration base 31. The output end of the vibrator 32 is set to vibrate with the surface of the hopper 15 through the vibration base 31.

[0041] The vibrator 32 and the hopper 15 structure generate vibration, at which time the concrete material is discharged from the bottom of the hopper 15 faster due to the vibration.

[0042] In this embodiment: a casting mechanism 4 is installed on the side wall of the concave bracket 11. The casting mechanism 4 includes a square frame 41 installed on the side wall of the concave bracket 11. An upper top plate 42 is provided at the top center of the square frame 41. A transmission roller shaft 43 is installed at the top center of the upper top plate 42.

[0043] The transmission roller shaft 43 is used to change the position of the upper concave bracket 11.

[0044] In this embodiment: a transmission base 44 is installed at the top of the transmission roller shaft 43, a support rod 45 is installed at the top of the transmission base 44, a bearing frame 47 is hinged to the top of the support rod 45 through the scheduling roller shaft 46, and an I-shaped bracket 48 is installed at the top of the bearing frame 47.

[0045] The system employs a scheduling roller 46 and a support frame 47. The I-shaped bracket 48 allows for easy adjustment of the elevation angle of the support frame 47 to facilitate the opening and closing of the hopper for material discharge and to prevent material blockage.

[0046] In this embodiment: A telescopic bracket 49 is connected to the middle of the top of the I-shaped bracket 48. A shaping mechanism 5 is installed at the end of the telescopic bracket 49. The shaping mechanism 5 includes an upper sliding ring 51 installed on the side wall of the telescopic bracket 49. A plurality of fastening holes 52 are sequentially opened on the top surface of the upper sliding ring 51. A lifting sliding rod 53 is installed at the top of each of the plurality of fastening holes 52. A lower sliding ring 54 is sleeved at the bottom of the lifting sliding rod 53.

[0047] The lifting sliding rod 53 is used to change the position and height of the upper sliding ring 51, and the position of the sliding ring is changed up and down. While pouring material, it is smoothed and shaped, and gradually cast into a column shape, thus preventing the twisting and skewing of the finished structural column.

[0048] In this embodiment: the bottom of the lower sliding ring 54 is supported by the ground, and a conical cover 55 is installed at the top of the upper sliding ring 51. A feeding opening 56 is opened at the top of the conical cover 55, and a conduit 57 is connected to the top of the feeding opening 56. The other end of the conduit 57 is connected to the bottom position of the hopper cover 22 through a material pump.

[0049] The concrete material is delivered through the delivery opening 56 and the guide pipe 57, and at this moment, the concrete material reaches the surface of the delivery opening 56 from the position of the guide pipe 57 to achieve downward penetration.

[0050] In practical use, step one: delivery of concrete pouring materials;

[0051] At this time, personnel need to put the material into the hopper 15 from the position of the trough 16. When the material needs to be discharged, the personnel discharge the material from the hopper cover 22 according to the hinge 21. According to the connection of the hinge 21, the hopper cover 22 is hinged to one end of the corresponding actuating plate 26 from the cylinder body of the pneumatic cylinder 27. After the pneumatic cylinder 27 extends and retracts, it controls the linkage plate 28, which drives the closed door 23 to change from closed to open. The unobstructed structural column concrete will be pumped from the hopper cover 22 into the guide pipe 57 through the material pump.

[0052] Step 2: Speed ​​up material feeding;

[0053] When the vibrator 32 is powered on, it generates oscillation. The vibration is transmitted through the vibrating base 31 and accelerates the discharge of material from the hopper 15. The vibration can cause the concrete attached to the hopper 15 to fall down and avoid blockage.

[0054] At this time, the transmission roller shaft 43 is hinged at one end, which drives the transmission base 44 to rotate, changing the direction of the telescopic support 49. According to the up and down change of the bearing frame 47, the position of the telescopic support 49 and the upper sliding ring 51 is changed. The conical cover 55 is inserted into the feeding opening 56 through the guide tube 57, and the body of the lifting sliding rod 53 slides. The position of the upper sliding ring 51 is changed by using the hole position of the fastening opening 52, thereby changing the accumulation and shaping of the concrete raw material of the structural column.

[0055] The contents not described in detail in this description are existing technologies known to those skilled in the art. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
