Description

Technical Field

[0001] This utility model relates to the field of building tools technology, and in particular to an adjustable template for structural columns. Background Technology

[0002] For multi-story brick-concrete structures, reinforced concrete structural columns need to be cast on-site at vulnerable parts of the walls (the four corners of the exterior walls, the junctions of staggered floors, both sides of large openings, and the junctions of interior and exterior walls of large rooms, etc.) and connected to the ring beams of each floor to form a flexural and shear-resistant spatial frame to improve the overall structural integrity and collapse resistance. The cross-section and reinforcement requirements of the structural columns vary depending on the number of building stories and the seismic intensity; therefore, the formwork must be adjustable and adaptable.

[0003] The current construction generally uses wooden formwork: two main boards are placed on the front and back sides of the pre-reserved toothed joint in the brick masonry, multiple back ribs are nailed horizontally, and then tie rods are inserted and tightened. A "trumpet-shaped" feed port is temporarily nailed on the top to complete the concrete pouring.

[0004] The structural columns obtained by casting the above-mentioned template structure have certain problems. The flared opening forms a concrete protrusion at the top of the column that is the same size as the inner contour of the opening. It needs to be manually chiseled and repaired later, which is labor-intensive, time-consuming and easily damages the density of the column top. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable template for structural columns to solve the problems mentioned in the background art.

[0006] This utility model provides an adjustable template for a structural column, including a wall and a pair of baffles. The baffles are respectively disposed on the front and rear sides of the wall, and a feed hopper is fixedly connected to the upper front end of the baffle located on the front side of the wall; it also includes: A sealing mechanism is installed inside the feed hopper; A drive mechanism is installed below the feed hopper and is used to drive the sealing mechanism to operate.

[0007] Preferably, each of the two pairs of baffles has a reinforcing member fixedly connected to one end facing away from the other. The reinforcing member includes a reinforcing rib, and there is a pair of reinforcing ribs arranged vertically. The baffle between the reinforcing ribs has a through hole, and a fixing rod is embedded inside the through hole. The front and rear side walls of the fixing rod have threaded grooves, and the front and rear side walls of the fixing rod are fitted with gaskets. The end of the gasket near the baffle abuts against the reinforcing rib. Nuts are fixedly connected to both ends of the fixing rod by threads.

[0008] Preferably, the sealing mechanism includes a sealing plate, which is rotatably connected inside the feed hopper. Arc-shaped tubes are fixedly connected symmetrically to the front and rear of the baffle. The ends of the arc-shaped tubes are fixedly connected to the outer wall of the front side of the feed hopper. Arc-shaped rods are slidably connected to the inner wall of the arc-shaped tubes. The output end of the arc-shaped rods extends into the feed hopper and is fixedly connected to the front end of the sealing plate.

[0009] Preferably, the arc-shaped rod has equidistant grooves on its sidewall, and the arc-shaped tube has clearance holes on its outer wall.

[0010] Preferably, the drive mechanism includes a rotating shaft, which is rotatably connected to the front side wall of the feed hopper via a bearing seat. Gears are fixedly connected to both the front and rear side walls of the rotating shaft. The gears are located inside the clearance hole and mesh with the tooth groove. A worm gear is fixedly connected to the middle side wall of the rotating shaft. A mounting bracket is fixedly connected to the front end of the feed hopper. A worm is rotatably connected between the mounting bracket and the feed hopper. The worm meshes with the worm wheel. A handle is fixedly connected to the front end of the worm.

[0011] Preferably, the front end face of the feed hopper is provided with a discharge port, and a guide pipe is fixedly connected to the front end of the feed hopper, and the guide pipe is connected to the discharge port.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a rotatable sealing plate installed inside the feed hopper; during pouring, the sealing plate is opened, and the concrete smoothly enters the column body along the hopper wall; after filling, rotating the sealing plate can cut off the hopper cavity from the top of the column, and the excess concrete is automatically discharged through the discharge port and guide pipe, so that no hard protrusion is formed on the top of the column, completely eliminating the need for later chiseling and repair processes, significantly shortening the finishing time, and ensuring that the concrete at the top of the column is dense and intact.

[0013] 2. This utility model allows the sealing plate to cut off the hopper cavity from the column top by rotating the handle, which is highly accurate and easy to operate; the worm gear and worm wheel have a reverse self-locking function, which can effectively resist the impact of pouring and prevent the sealing plate from rotating on its own, thus ensuring construction safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-5 As shown, this utility model has the following two specific embodiments. Example 1

[0018] An adjustable formwork for structural columns includes a wall 1 and a pair of baffles 2, the baffles 2 being respectively disposed on the front and rear sides of the wall 1, with a feed hopper 25 fixedly connected to the upper front end of the baffle 2 located on the front side of the wall 1; it also includes: Sealing mechanism 3 is installed inside the feed hopper 25; Drive mechanism 4 is installed below the feed hopper 25 and is used to drive the sealing mechanism 3 to operate. A pair of baffles 2 are fixedly connected to a reinforcing member at opposite ends. The reinforcing member includes a reinforcing rib 21. There is a pair of reinforcing ribs 21 distributed vertically. The baffle 2 located between the reinforcing ribs 21 has a through hole. A fixing rod 22 is embedded in the through hole. The front and rear side walls of the fixing rod 22 have threaded grooves. The front and rear side walls of the fixing rod 22 are fitted with a gasket 23. The end of the gasket 23 near the baffle 2 abuts against the reinforcing rib 21. Nuts 24 are fixedly connected to both ends of the fixing rod 22 by threads. The front end face of the feed hopper 25 is provided with a discharge port 251, and a guide pipe 252 is fixedly connected to the front end of the feed hopper 25. The guide pipe 252 is connected to the discharge port 251.

[0019] In this embodiment, as Figures 1-2As shown, a pair of baffles 2 are tightly attached to the front and rear facades of the wall 1, forming a reliable tension with the fixing rod 22 via reinforcing ribs 21. After tightening the nuts 24 at both ends of the fixing rod 22, the formwork system has sufficient rigidity to resist the lateral pressure of the concrete and avoid bulging. Before pouring, the sealing mechanism 3 is adjusted by the drive mechanism 4 to open the channel between the hopper cavity and the column top, at which point a complete injection cavity is formed inside the feed hopper 25. Concrete is injected into the feed hopper 25 by the pump pipe and flows smoothly into the column cavity along the hopper wall. When the column is about to be filled, the drive mechanism 4 adjusts the sealing mechanism 3 to isolate the feed hopper 25 from the column top in time. Excess concrete is discharged to the recycling bucket through the discharge port 251 and the guide pipe 252, leaving the column top surface flat without protrusions. After the concrete has initially set, the nuts 24 are loosened and the fixing rod 22 is pulled out, allowing the baffles 2 on both sides to be quickly removed, realizing early formwork removal and recycling. Example 2

[0020] The difference from Embodiment 1 is that this embodiment discloses the specific structures of the sealing mechanism 3 and the driving mechanism 4; The sealing mechanism 3 includes a sealing plate 31, which is rotatably connected inside the feed hopper 25. Arc-shaped tubes 32 are fixedly connected to the front and rear of the baffle 2. The ends of the arc-shaped tubes 32 are fixedly connected to the front outer wall of the feed hopper 25. Arc-shaped rods 33 are slidably connected to the inner wall of the arc-shaped tubes 32. The output end of the arc-shaped rods 33 passes through the inside of the feed hopper 25 and is fixedly connected to the front end of the sealing plate 31. The side wall of the arc-shaped rod 33 is provided with toothed grooves 331 at equal intervals, and the outer wall of the arc-shaped tube 32 is provided with clearance holes 321; The drive mechanism 4 includes a rotating shaft 41, which is rotatably connected to the front side wall of the feed hopper 25 via a bearing seat. Gears 42 are fixedly connected to both the front and rear side walls of the rotating shaft 41. The gears 42 are located inside the clearance hole 321 and mesh with the tooth groove 331. A worm gear 43 is fixedly connected to the middle side wall of the rotating shaft 41. A mounting bracket 44 is fixedly connected to the front end of the feed hopper 25. A worm 45 is rotatably connected between the mounting bracket and the feed hopper 25. The worm 45 meshes with the worm gear 43. A handle 46 is fixedly connected to the front end of the worm 45.

[0021] In this embodiment, as Figures 3-5 As shown, when the handle 46 drives the worm gear 45 to rotate, the worm gear 45 drives the worm wheel 43 and the rotating shaft 41 to rotate synchronously. The gears 42 fixed at both ends of the rotating shaft 41 mesh with the tooth grooves 331 of the arc-shaped rod 33 at the clearance hole 321, converting the rotational motion into the precise arc sliding of the arc-shaped rod 33, thereby realizing the angle adjustment of the sealing plate 31. When the sealing plate 31 closes upward, the excess concrete at the top of the column is automatically discharged along the discharge port 251 and the guide pipe 252. After the concrete has initially set, the nut 24 can be loosened and the fixing rod 22 can be pulled out, allowing the baffles 2 on both sides to be quickly removed, realizing early removal and recycling of the formwork.

[0022] The working principle of this utility model is as follows: A pair of baffles 2 are attached to the two sides of the toothed joint of the wall 1. The fixing rod 22 is passed through the through hole and the washers 23 are put into both ends in sequence. The nuts 24 are tightened. The upper and lower reinforcing ribs 21 form a tension system, so that the formwork can obtain the rigidity to resist the lateral pressure of the concrete. At this time, the feed hopper 25 is located at the top of the baffle 2 and is connected to the column cavity. Turning the handle 46 clockwise drives the worm gear 45 to drive the worm wheel 43 to rotate. The rotation of the worm wheel 43 drives the rotating shaft 41 to rotate, which in turn drives the gears 42 at both ends to rotate synchronously. Then, the gears 42 mesh with the tooth groove 331 of the arc rod 33 through the clearance hole 321, pushing the arc rod 33 to move inward along the arc tube 32. As a result, the arc rod 33 pulls the sealing plate 31 to flip to the inclined position, and the bottom of the hopper cavity is fully opened, forming a smooth material injection channel. Pumped concrete is injected from above the feed hopper 25 and flows down the hopper wall into the column cavity; the volume of the hopper cavity is greater than the pumping volume in one go, which can reduce impact air bubbles and improve the density of the column body; When it is observed that the mortar is about to reach the column top elevation, the handle 46 is turned counterclockwise, and each transmission component moves in the opposite direction. The arc rod 33 pushes the sealing plate 31 to flip upward to the vertical position, immediately cutting off the connection between the hopper and the column top. At this time, the excess concrete is automatically discharged through the discharge port 251 and the guide pipe 252, and the column top surface remains flat without the traditional horn-shaped protrusion. After the concrete has initially set, loosen nut 24, pull out fixing rod 22, and then slide baffle 2 outward to detach it from the wall. Sealing plate 31 remains in feed hopper 25 and is hoisted with the formwork to the next structural column location, achieving rapid early removal and reuse. Throughout the process, the self-locking characteristics of the worm gear 45 and its intermeshing ensure that sealing plate 31 will not shift under pumping impact, guaranteeing construction safety and molding quality.

[0023] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
