Description

Technical Field

[0001] The utility model relates to the technical field of building construction moulds, in particular to a rotatable corbel-free structural column feeding port. Background Art

[0002] A structural column refers to a reinforced concrete column set in the wall of a multi-layer brick-concrete structure in order to enhance the integrity and stability of the building. The structural column is connected to the ring beams of each layer to form a space frame that can resist bending and shearing. It is an effective measure to prevent the collapse of the house. The structural column is set at the four corners of the outer wall, the intersection of the horizontal wall and the outer longitudinal wall at the staggered level, on both sides of the larger opening, and at the intersection of the inner and outer walls of the large room. In order to facilitate the pouring of concrete, the upper part of the structural column template usually uses a template reserved for feeding. For the post-cast structural column, since there is a ring beam at the upper end, the feeding port can only be set on the side of the upper part, and the concrete is poured through the feeding port set at the side. After the concrete pouring construction is completed, a horizontally extended concrete corbel will be left at the top of the structural column. The concrete corbel needs to be removed later, and the feeding port needs to be re-processed and installed when the next structural column template is installed. Although this on-site processing and one-time use of the feeding port solves the problem of concrete feeding of the structural column, it also generates certain labor costs and material costs, and the template turnover rate is low. After the concrete corbel is removed, the visual quality of the structural column is seriously affected. Chinese patent 2022200612385 discloses "A tool for secondary structural columns to facilitate sporadic concrete pouring", with the announcement number CN217734882U. A flow outlet is set at the trapezoidal box and the right end. The top of the trapezoidal box is rotatably connected to a sealing plate that matches the flow outlet, and the bottom of the trapezoidal box is fixedly connected to a telescopic rod. The tool adds concrete into the trapezoidal box through the feeding port, aligns the flow outlet with the place where pouring is required, and tilts the trapezoidal box to pour out the concrete in the trapezoidal box. The operation is simple and convenient, and the concrete is not easy to scatter, thereby saving a certain amount of resources. However, this tool for pouring concrete can only solve the problem of pouring concrete, and still needs to cooperate with the traditional disposable feeding port. The feeding port cannot be reused, and there are still redundant concrete corbels that need to be removed after pouring is completed. Summary of the invention

[0003] In view of the above technical problems, the utility model provides a rotatable feeding port for structural columns that does not require cutting of the corbels. After the casting is completed, no redundant concrete corbels will be formed on the structural columns. The feeding port has a simple structure, is easy to use, and can be reused, thereby speeding up the construction progress, reducing labor and lowering construction costs.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model discloses a rotatable feeding port of a structural column which does not require the removal of the corbels, comprising a feeding channel of a rectangular cylindrical structure, a channel side hole being opened on one side of the feeding channel, a side plate being hinged on the channel side hole, side panels perpendicular to the side panels being arranged on both sides of the side panels, a hook being arranged on the end of the side panel away from the side panel, and positioning columns adapted to the hooks being arranged on the outer walls of the feeding channel on both sides of the channel side hole.

[0006] Through this solution, the feeding port has a simple structure, is easy to use and reusable. No excess concrete corbels will be left after pouring concrete, which can save the manpower and material resources spent on manually removing the corbels, thereby speeding up the construction progress, reducing labor and lowering the construction cost.

[0007] Preferably, a vibrator is fixedly mounted on the outer wall of the side plate.

[0008] Through this solution, the concrete near the feeding port is vibrated and compacted, which is beneficial to improving the quality of concrete pouring.

[0009] Preferably, the lower end of the side panel is hinged on the lower edge of the channel side hole, the side panel is a triangular plate structure with the bottom edge fixedly connected to the edge of the side panel, and the hook is arranged on the vertex of the side panel.

[0010] According to the solution, when the side panels are opened to cast concrete, the side panels and the side edge panels form a dustpan-shaped channel, which can prevent concrete from leaking.

[0011] Preferably, the hook includes a hook seat fixedly connected to the side panel, a hook head fixedly connected to one end of the hook seat, a hook plate hinged to the other end of the hook seat, and a torsion spring installed on the hook plate. The front end of the hook head is semicircular and invades the rotation trajectory of the hook plate. The torsion spring pushes the hook plate and overlaps the hook plate on the hook head.

[0012] Through this solution, the opening and closing of the side panels can be facilitated.

[0013] Preferably, the front end of the hook head is provided with a hook head step for overlapping the hook plate, and the front end of the hook plate is provided with a hook plate step adapted to the hook head step.

[0014] Through this solution, the hook head and the hook plate are firmly overlapped and accurately positioned.

[0015] Preferably, a limiting screw is inserted through the two parallel side walls of the feeding channel, and a limiting nut is installed on the limiting screw.

[0016] This solution facilitates the assembly and disassembly of the feeding channel.

[0017] The utility model has the advantages of simple structure, convenient use and repeatability, and no redundant concrete corbels will be left after pouring concrete, thus saving manpower and material resources spent on manually cutting off the corbels, thereby speeding up the construction progress, reducing manpower and lowering the construction cost.

In order to facilitate assembly and disassembly, the steel plates cannot be welded, and a limit screw 8 is inserted through the two parallel side walls of the feed channel 1, and a limit nut is installed on the limit screw 8, and the limit nut is located on the outside of the steel plate. During assembly, after adjusting the spacing between the two side walls, tighten the limit nut.

[0024] The side plate 3 is hinged on the side hole 2 of the channel. Figure 2 As shown, the lower end of the side panel 3 is hinged on the lower edge of the channel side hole 2, and the two are connected by a hinge, and the upper end of the side panel 3 can be turned outward; the side panels 4 perpendicular to the side panels 3 are arranged on both sides of the side panel 3, and the side panels 4 are triangular plate structures with the bottom edges fixedly connected to the edges of the side panels 3. The side panels 3 and the side panels 4 on both sides together form a dustpan-like structure, as shown in FIG. Figure 1 As shown, when the side plate 3 is opened outward, the side plate 3 is tilted and overlapped on the channel side hole 2. When pouring, the concrete flows into the feeding channel 1 along the side plate 3. After the pouring is completed, as shown in FIG. Figure 2As shown, the side plate 3 is closed, and the inner wall of the side plate 3 is flush with the inner wall of the feeding channel 1, and no redundant bracket structure is left; a hook 5 is provided on the side plate 4 at one end away from the side plate 3, and the hook 5 is provided on the vertex of the triangular side plate 4. Positioning columns 6 adapted to the hook 5 are provided on the outer wall of the feeding channel 1 on both sides of the channel side hole 2. When the side plate 3 is closed, the position of the side plate 3 can be locked by hanging the hook 5 on the positioning column 6, and the concrete is waiting for solidification. In addition, a vibrator 7 is fixedly installed on the outer wall of the side plate 3. The vibrator 7 can vibrate and finish the concrete in the channel side hole 2 after the concrete pouring is just completed and the side plate 3 is closed, so as to improve its surface quality and avoid defects such as bubbles, honeycombs, and rough surfaces of the concrete. In addition, a handle is provided on the vibrator 7. When pouring concrete, the position of the side plate 3 can be stabilized by holding the vibrator 7 and the side plate 3 by the handle, and the handle can be used to assist in applying force when vibrating and finishing, so as to improve the efficiency of vibrating and finishing.

[0025] like Figure 3 As shown, the hook 5 comprises a hook seat 51 fixedly connected to the side plate 4, a hook head 52 fixedly connected to one end of the hook seat 51, a hook plate 53 hinged to the other end of the hook seat 51, and a torsion spring 54 installed on the hook plate 53. The hook plate 53 is rotatably connected to the hook seat 51 through a hinge shaft. The front end of the hook head 52 is semicircular and intrudes into the rotation track of the hook plate 53. The torsion spring 54 pushes the hook plate 53 and overlaps the hook plate 53 on the hook head 52. The torsion spring 54 is installed on the hinge shaft of the hook plate 53. One end of the torsion spring 54 is fixedly connected to the hook seat 51, and can also be hooked on a fixed point of the hook seat 51. The other end of the torsion spring 54 overlaps the hook plate 53, generating a certain driving force on the hook plate 53, so that its front end is pressed on the hook head 52. The front end of the hook head 52 has a hook head step 521 for overlapping the hook plate 53, and the front end of the hook plate 53 has a hook plate step adapted to the hook head step 521. Figure 1 , Figure 2 As shown, when the hook plate 53 is overlapped on the hook head 52, the hook plate step and the hook head step 521 are engaged with each other, and the hook plate 53 and the hook head 52 form a closed ring, which can cover the positioning column 6, thereby limiting the position of the side plate 3; Figure 3 As shown, when the hook plate 53 is pushed open by an external force, a gap is generated between the hook plate 53 and the hook head 52, allowing the positioning column 6 to enter and exit through the gap.

[0026] When in use, the feeding port is set at the corresponding structural column position, and the steel plate constituting the feeding channel 1 is closely attached to the wall on both sides of the structural column according to the position of the structural column, and the limiting screw 8 is passed through the parallel two side walls of the feeding channel 1, and fixed by the limiting nut, so that the steel plate of the feeding channel 1 is vertical and not easy to tilt. When pouring concrete, open the side plate 3 and tilt it about 45 degrees, and form a dustpan opening with a large top and a small bottom on one side of the feeding channel 1, and pour a proper amount of concrete through the dustpan opening. After the pouring is completed, close the side plate 3 to make the side plate 3 vertical, and then open the vibrator 7 to slightly vibrate the concrete inside the side plate 3 to finish the surface. After the vibrating and finishing is completed, close the vibrator 7, hang the hook 5 on the positioning column 6, and fix the position of the side plate 3. After the initial setting of the concrete and before the final setting, open the side plate 3, disassemble the feeding channel 1, and save it after cleaning for reuse.
