Description

Technical Field

[0001] This invention belongs to the field of construction equipment technology, specifically relating to a molding and sealing device for pouring structural columns. Background Technology

[0002] To enhance the integrity and stability of buildings, reinforced concrete structural columns should be installed in the walls of multi-story brick-concrete structures. These columns, connected to the ring beams of each floor, form a spatial frame that can resist bending and shearing, effectively preventing the building from collapsing.

[0003] In the current construction, only one concrete pouring port is reserved at the junction of the top of the structural column and the bottom of the beam. Due to the spatial constraints of the pouring port, a wedge-shaped funnel-shaped guide pouring device that can be fixed to the outside of the pouring port is usually used to assist in the pouring process.

[0004] For example, patent (CN204590631U) discloses a concrete column pouring tool with an inclined guide plate located between two side plates. A sleeve is provided at the lower end of the guide plate, and the guide plate is fitted onto a fixed shaft through the sleeve so that the guide plate can rotate around the fixed shaft. This concrete column pouring device ensures that the concrete column is formed in one go, significantly reducing the construction cost of concrete column pouring and reducing the workload of workers. However, the following problems still exist: after the concrete is poured, the pouring opening needs to be sealed. This requires not only timely removal of the pouring device but also the addition of an extra sealing structure, thus failing to achieve the technical effect of convenient construction. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a molding and sealing device for the casting of structural columns, so as to solve the technical problem that the existing diversion casting device lacks an integrated sealing structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A molding and sealing device for casting structural columns includes a flow guiding unit and a sealing unit arranged opposite to each other. The flow guiding unit includes a fixed plate with an opening at the top and uprights formed on both sides of the opening. The sealing unit includes a first limiting strip and a second limiting strip fixedly connected to the uprights on both sides. A sliding plate is slidably connected between the first limiting strip and the second limiting strip. The height and thickness of the first limiting strip, the second limiting strip, and the sliding plate are the same, and the height is greater than the height of the opening. The height of the fixed plate is greater than the sum of the heights of the opening and the sliding plate.

[0008] Furthermore, the inner surface of the first limiting strip is concave to form an arc surface. A limiting groove is formed on the side of the sliding plate facing the first limiting strip. A sliding block of the same height as the limiting groove is provided between the sliding plate and the first limiting strip. Part of the sliding block extends into the limiting groove and slides along the depth direction of the limiting groove, connecting it to the sliding plate. Multiple horizontally spaced elastic connecting members are evenly arranged between the bottom surface of the sliding block and the bottom of the limiting groove along the height direction. These elastic connecting members are always in a compressed state. The side of the sliding block away from the limiting groove... The outer surface of the sliding plate is convex and arc-shaped, and the curvature is consistent with the inner surface of the first limiting strip. The inner surface of the second limiting strip is a periodically continuous undulating curved surface, and an arc-shaped limiting groove is opened in the middle of the curved surface. A semi-circular rotating groove is opened on the side of the sliding plate facing the second limiting strip. The vertical distance from the lowest point of the rotating groove to the bottom surface of the sliding plate is greater than the vertical distance from the bottom surface of the first limiting strip to the bottom surface of the fixed plate. A rotating disk is rotatably connected to the opening of the rotating groove. The side of the rotating disk is convex and arc-shaped and is adapted to the limiting groove on the inner surface of the second limiting strip.

[0009] Furthermore, two opposing semi-circular protrusions are welded to both sides of the rotating groove. The axis of the protrusions penetrates the center of the rotating groove. A crossbar limiting groove is opened at the center of the inner side of the protrusion. A crossbar that matches the crossbar limiting groove is provided at the center of both sides of the rotating disk.

[0010] Furthermore, the first limiting strip and the second limiting strip have through grooves on their sides perpendicular to the side direction. A first handle is fixedly connected to the outer arc surface of the sliding block, and the first handle passes through the through groove and protrudes from the first limiting strip. A second handle is fixedly connected to the side of the sliding plate away from the sliding block, and the second handle passes through the through groove and protrudes from the second limiting strip.

[0011] Furthermore, multiple first rolling shafts are spaced apart along the height direction below the first limiting strip. Each first rolling shaft includes a cylindrical first shaft perpendicular to the fixed plate and a first rotating body rotatably connected to the first shaft. The cross-section of the first rotating body is circular, and the diameter of the first rotating body gradually decreases from both ends inward along its length to form a concave arc surface. The concave arc surface is adapted to the convex arc surface of the sliding block. The concave arc surface of the first rotating body coincides with the projection of the inner arc surface of the first limiting strip in the vertical direction. Multiple second rolling shafts are spaced apart along the height direction below the second limiting strip. Each second rolling shaft includes a cylindrical second shaft perpendicular to the fixed plate and a cylindrical second rotating body rotatably connected to one end of the second shaft. When the rotating disk is located at the deepest point of the inner curved surface of the second limiting strip, the side of the sliding plate is in contact with the side of the second rotating body.

[0012] Furthermore, the bottom of the fixed plate is provided with a fixed limiting block for providing limiting support for the sliding plate. The vertical distance from the top surface of the fixed limiting block to the bottom surface of the opening is equal to the height of the sliding plate. Below the first limiting strip and the second limiting strip, there is a sliding limiting block that moves in the horizontal direction. The vertical distance from the top surface of the sliding limiting block to the top surface of the upright is the same as the height of the sliding plate.

[0013] Furthermore, the flow guiding unit includes a right-angled triangular side plate that is fixed perpendicularly to the column. The side of the side plate with the short right-angled side is in contact with the side of the column, and the length of the short right-angled side of the side plate is equal to the height of the opening. The top surface of the side plate with the long right-angled side is flush with the top surface of the column.

[0014] Furthermore, a rotating plate is provided below the side plate, which is used to close the bottom surface where the inclined surfaces of the two side plates are located.

[0015] Furthermore, a fixing rod with protruding ends is provided on the bottom surface of the rotating plate along the length direction of the rotating plate. The fixing rod is fixedly connected to the bottom surface of the rotating plate through a fixing bracket. A hook is rotatably connected to the outer side surface of the side plate, and the hook is used to hook the fixing rod.

[0016] The beneficial effects of this invention are as follows:

[0017] (1) Compared with the prior art, when concrete is poured, the sliding plate slides down until the opening is fully exposed. When the pouring port needs to be sealed after the concrete is poured, the sliding plate slides down until the opening is completely blocked, thereby sealing the pouring port. The sealing unit and the diversion unit adopt an integrated design. After the concrete is poured, the pouring port can be sealed without removing the diversion device, which significantly enhances the applicability of the whole device and effectively improves the convenience and efficiency of construction.

[0018] (2) In addition, the elastic connector is always in a compressed state, so that the rotating disk on the other side of the sliding plate abuts against the inner curved surface of the second limiting strip. During the upward movement of the sliding plate, the rotating disk rolls on the continuously undulating inner surface, so that the sliding plate can slide back and forth to smooth the concrete at the pouring opening while rising, so that a dense, uniform, smooth and durable surface layer is formed on the surface of the pouring opening, which not only improves the physical and mechanical properties of the structural column, but also has an aesthetic effect.

Detailed Implementation

[0034] Example 1, specifically as follows Figures 1-12 As shown.

[0035] A molding and sealing device for casting structural columns includes a flow guiding unit and a sealing unit arranged opposite to each other, such as... Figure 1 As shown, the flow guiding unit includes a rectangular fixing plate 1. The opening 11 at the top of the fixing plate 1 is the concrete flow channel. The size of the opening 11 matches the size of the pouring port. Uprights 12 are formed on both sides of the opening 11.

[0036] A right-angled triangular side plate 2 is welded to one side of the fixed plate 1. The surface of the side plate 2 is perpendicular to the surface of the fixed plate 1. The side of the side plate 2 containing the shorter right-angled side contacts the outer surface of the upright 12, and the length of the shorter right-angled side of the side plate 2 is equal to the height of the opening. The top surface of the side plate 2 containing the longer right-angled side is in the same horizontal plane as the top surface of the upright 12. The outer surface of the side plate 2 is in the same plane as the side of the fixed plate 1. This technical solution effectively ensures the length of the guide section in the guide unit and the accommodating space of the entire guide channel.

[0037] like Figure 1 , Figure 2 As shown, a semi-cylindrical lug 13 is provided on the side of the fixing plate 1 facing the side plate 2. The lug 13 is located below the side plate 2 and close to the inclined surface of the side plate 2. The thickness of the lug 13 is less than the thickness of the side plate 2, and the lug 13 is integrally formed with the fixing plate 1. An opening is provided between the two lugs 13. Figure 3 The mounting groove 32 shown has a circular cross-section, and its inner diameter is the same as the radius of the lug 13. A rotating shaft 33 of the same length as the mounting groove 32 is provided within the mounting groove 32. The radius of the rotating shaft 33 is smaller than the inner diameter of the mounting groove 32. Cylindrical limiting protrusions are integrally formed at both ends of the rotating shaft 33. Limiting grooves are formed on both sides of the mounting groove 32, and the rotating shaft 33 is rotatably connected to the lugs 13 on both sides through these limiting grooves.

[0038] A rotating plate 31 of the same length as the mounting groove 32 is welded to the side of the rotating shaft 33. The width of the rotating plate 31 is the same as the side length of the inclined side of the side plate 2. When the rotating plate 31 rotates counterclockwise until the upper surface of the rotating plate 31 is in contact with the inclined surfaces of the two side plates 2, the top edge of the rotating plate 31 is in the plane where the top surface of the side plate 2 is located, and the flow guiding unit reaches the working state.

[0039] To fix the rotating plate 31 in the working state, a fixing rod 34 is specially provided below the rotating plate 31, and the fixing rod 34 is located at the middle position of the lower surface of the rotating plate 31. The extension direction of the fixing rod 34 is consistent with the length direction of the rotating plate 31, and both ends of the fixing rod 34 extend out of the outer plate surface of the side plate 2. Two rods are distributed at intervals along the rod body of the fixing rod 34. Figure 4 The fixed bracket 35 shown is used to lock the fixed rod 34 to the side plate 2.

[0040] like Figure 5 As shown, a horizontal bar 36 perpendicular to the plate surface is welded on the outer plate surface of the side plate 2. The horizontal bar 36 is located directly above the fixed rod 34. A coaxial limiting block 38 is welded on the outer end face of the horizontal bar 36. A sleeve 37 is fitted on the part of the horizontal bar 36 between the limiting block 38 and the side plate 2. The inner diameter of the sleeve 37 is the same as the diameter of the horizontal bar 36. The sleeve 37 is rotatably connected to the horizontal bar 36. A hook 39 is welded on the outer side face of the sleeve 37. The bent part of the hook 39 is adapted to the fixed rod 34.

[0041] The fixed plate 1 has a side facing away from the flow guiding unit, as shown in the image. Figure 1 The sealing unit shown includes a first limiting strip 41 and a second limiting strip 42 welded to the two side uprights 12, respectively. The first limiting strip 41 and the second limiting strip 42 have the same height and thickness. The length of the cross-section of the first limiting strip 41 is less than the length of the cross-section of the upright 12, the outer surface of the first limiting strip 41 is flush with the outer surface of the upright 12, and the inner surface of the first limiting strip 41 is concave to form an arc surface. Similarly, the length of the cross-section of the second limiting strip 42 is less than the length of the cross-section of the upright 12, and the outer surface of the second limiting strip 42 is flush with the outer surface of the upright 12. It is particularly important to emphasize that, as... Figure 6 As shown, the inner surface of the second limiting strip 42 is a periodically continuous undulating curved surface, and an arc-shaped limiting groove 421 is opened in the middle of the curved surface.

[0042] A rectangular sliding plate 43 of uniform height and thickness is provided between the first limiting strip 41 and the second limiting strip 42. Spacing is left between both sides of the sliding plate 43 and the first limiting strip 41 and the second limiting strip 42, respectively. Figure 7As shown, a rectangular groove 51 is formed in the middle of the side of the sliding plate 43 facing the first limiting strip 41. A sliding block 52, at the same height as the limiting groove 51, is provided between the sliding plate 43 and the first limiting strip 41. Part of the sliding block 52 extends into the limiting groove 51 and slides along the depth direction of the limiting groove 51, connecting it to the sliding plate 43. Multiple horizontal elastic connectors 53 are evenly spaced along the height direction between the bottom surface of the sliding block 52 and the bottom of the limiting groove 51. In this embodiment, the elastic connectors 53 are springs. One end of the spring is welded to the bottom of the limiting groove 51, and the other end is welded to the side of the sliding block 52. The elastic connectors 53 achieve an elastic connection between the sliding block 52 and the sliding plate 43. The side of the sliding block 52 away from the limiting groove 51 convexes outward into an arc surface, and the arc is consistent with the inner surface of the first limiting strip 41, thereby achieving surface contact between the sliding block 52 and the first limiting strip 41.

[0043] In order to ensure sufficient travel of the sliding plate 43, in this embodiment, the height of the first limiting strip 41 is greater than the height of the opening 11.

[0044] like Figures 8-10 As shown, a rotating groove 431 is formed on the side of the sliding plate 43 facing the second limiting strip 42. The longitudinal section of the rotating groove 431 is semi-circular. It should be noted that the vertical distance from the lowest point of the rotating groove 431 to the bottom surface of the sliding plate 43 is greater than the vertical distance from the bottom surface of the first limiting strip 41 to the bottom surface of the fixed plate 1. Two opposing semi-circular protrusions 432 are welded to both sides of the rotating groove 431. The axis of the protrusions 432 penetrates the center of the rotating groove 431. A rotating disk 54 is provided inside the rotating groove 431. The diameter of the rotating disk 54 is smaller than the diameter of the rotating groove 431. A crossbar limiting groove is formed at the center of the inner side of the protrusions 432. Crossbars that are adapted to the crossbar limiting groove are welded at the center of both sides of the rotating disk 54, thereby realizing the rotating connection between the rotating disk 54 and the protrusions 432. In addition, it is worth noting that the side of the rotating disk 54 is convex and arc-shaped, and is adapted to the limiting groove 421 on the inner side of the second limiting strip 42.

[0045] A through groove 55 is formed at the middle position of the side of the first limiting strip 41 and the second limiting strip 42, perpendicular to the side direction. On one side of the first limiting strip 41, one end of the cylindrical first handle 56 passes through the through groove 55 and is welded to the arc surface of the sliding block 52, while the other end of the first handle 56 protrudes from the outer side of the first limiting strip 41. On the other side of the second limiting strip 42, one end of the second handle 57 passes through the through groove 55 and is welded to the side of the sliding plate 43, while the other end of the second handle 57 protrudes from the outer side of the second limiting strip 42. It is important to emphasize that, in order to ensure sufficient travel of the sliding plate 43, both the first handle 56 and the second handle 57 are located above the rotating disk 54. The through groove 55, the first handle 56, and the second handle 57 facilitate the application of force to the sliding plate 43 and the lifting of the sliding plate 43.

[0046] The height of the fixed plate 1 is greater than the sum of the height of the opening 11 and the height of the sliding plate 43. This is to provide a continuous limiting effect on the sliding plate 43 below the first limiting strip 41, such as... Figure 11 , Figure 12 As shown, a first rolling shaft 44 and a second rolling shaft 47 perpendicular to the surface of the fixed plate 1 are respectively provided on both sides of the sliding plate 43's remote movement trajectory.

[0047] The first rolling shaft 44 includes a cylindrical first shaft body 441 perpendicular to the fixed plate and a first rotating body 442 rotatably connected to one end of the first shaft body 441. The end of the first shaft body 441 away from the first rotating body 442 is threadedly connected to the fixed plate 1. The cross-section of the first rotating body 442 is circular, and its diameter gradually decreases from both ends inward along its length to form a concave arc surface. The concave arc surface of the first rotating body 442 is adapted to the convex arc surface of the sliding block 52. It is particularly noteworthy that the projection of the concave arc surface of the first rotating body 442 and the inner arc surface of the first limiting strip 41 in the vertical direction coincides.

[0048] The second rolling shaft 47 includes a cylindrical second shaft body 471 and a second rotating body 472 rotatably connected to one end of the second shaft body 471. The end of the second shaft body 471 away from the second rotating body 472 is threadedly connected to the fixed plate 1. The second rotating body 472 is cylindrical. It should be noted that when the rotating disk 54 is located at the deepest point of the inner curved surface of the second limiting strip 42, the side of the sliding plate 43 is in contact with the side of the second rotating body 472.

[0049] With the sealing unit in place, during concrete pouring, the sliding plate 43 descends until the opening 11 is fully exposed. When sealing the pouring opening is required after concrete pouring, the sliding plate 43 rises until it completely covers the opening 11, thus sealing the pouring opening. The sealing unit and the diversion unit are integrated, allowing for pouring opening sealing without removing the diversion device after concrete pouring. This significantly enhances the applicability of the entire device and effectively improves construction convenience and efficiency.

[0050] Furthermore, the elastic connector 53 is always in a compressed state, causing the rotating disk 54 on the other side of the sliding plate 43 to abut against the inner curved surface of the second limiting strip 42. During the upward movement of the sliding plate 43, the rotating disk 54 rolls on the continuously undulating inner surface, allowing the sliding plate 43 to slide back and forth to smooth the concrete at the pouring opening. This promotes the formation of a dense, uniform, smooth, and durable surface layer at the pouring opening, which not only improves the physical and mechanical properties of the structural column but also enhances its aesthetic appeal.

[0051] It should be further noted that the bottom of the fixing plate 1 is also welded with something like... Figure 1 The rectangular fixed limiting block 45 shown has a cross-sectional length that matches the cross-sectional length of the upright 12, and a cross-sectional width that matches the thickness of the sliding plate 43. The vertical distance from the top surface of the fixed limiting block 45 to the bottom surface of the opening 11 is equal to the height of the sliding plate 43. When the sliding plate 43 slides down until its top surface is flush with the bottom surface of the opening 11, the fixed limiting block 45 provides support and limits for the sliding plate 43. At this time, the top surface of the sliding plate 43 can connect the opening 11 and the pouring port, preventing concrete from falling into the gap between the opening 11 and the pouring port during the pouring process.

[0052] Additionally, the fixed plate 1 has sliding grooves on both sides (not shown in the figure). One end of the groove is located directly below the limiting strip 4, and the other end extends horizontally to the bottom of the sliding plate 2. A cuboid sliding limiting block 46 is slidably connected to the groove. The length of the cross-section of the sliding limiting block 46 is less than the length of the cross-section of the first limiting strip 41. The vertical distance from the top surface of the sliding limiting block 46 to the top surface of the upright 12 is the same as the height of the sliding plate 43. When the sliding plate 43 slides upward until it completely covers the opening 11, the sliding limiting block 46 slides to the bottom of the sliding plate 43 and provides support for the sliding plate 43. Furthermore, the sliding of the sliding limiting block 46 to the bottom of the first limiting strip 41 does not affect the sliding of the sliding plate 43.

[0053] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
