Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a funnel device for pouring concrete at the top of a structural column. Background Technology

[0002] In current construction technology, cast-in-place concrete is commonly used for the construction of secondary structural columns in building buildings. As a critical component of the seismic-resistant structure, the quality of the structural column's construction directly affects the seismic resistance of the masonry structure. Currently, wooden formwork is often used on construction sites to support the structural columns, with a notch pre-reserved at the top. A wooden flared opening is installed at the notch for the concrete pouring inlet.

[0003] For the flared openings created with wooden formwork, the concrete needs to be chipped away after it has hardened. Since structural columns are commonly used seismic-resistant components in masonry projects, this chipping work is extensive, and the removed concrete cannot be reused, leading to material waste and generating a large amount of construction debris. It also increases labor costs. Chipping can easily damage the structural column, reducing its overall seismic performance and thus affecting its usability.

[0004] Therefore, developing a one-time molding device for pouring concrete at the top of structural columns has become an urgent problem for construction professionals. Utility Model Content

[0005] The purpose of this utility model is to provide a funnel device for pouring concrete at the top of a structural column, which can avoid secondary chiseling, simplify the construction process, improve construction efficiency, reduce material waste, and lower construction costs.

[0006] To achieve the above objectives, this utility model provides a casting funnel device for the top of a structural column, comprising an L-shaped side plate and a front panel disposed inside the L-shaped side plate. The L-shaped side plate and the front panel are connected by a rotating shaft. The L-shaped side plate is fixedly connected to the rotating shaft, and the front panel is rotatably connected to the rotating shaft. A first angle steel is welded to the outer side of the top corner of the two L-shaped side plates near the template position, and a second angle steel is welded to the outer side of the bottom corner of the two L-shaped side plates near the template position. Two L-shaped handles are welded to the front panel.

[0007] Preferably, a hollow steel cylinder is welded to the top of the first angle steel, the hollow steel cylinder is tangentially arranged with the first angle steel, a detachable L-shaped screw is provided inside the hollow steel cylinder, the L-shaped screw is made of plain round steel bar, and the hollow steel cylinder and the rotating shaft are arranged on the same vertical plane.

[0008] Preferably, the rotating shaft is fixedly disposed between the two L-shaped side plates, and the front panel rotates around the L-shaped side plates by rotating it with the rotating shaft. The side of the L-shaped side plate is an isosceles right triangle.

[0009] Preferably, the front panel has a sealed position and an open position during rotation. When the front panel is rotated to the open position, the front panel is away from the outlet of the funnel. When the front panel is rotated to the sealed position, the front panel closes the outlet.

[0010] Preferably, the edge of the L-shaped side panel is provided with a protrusion to fix the position of the front panel when it is open.

[0011] Preferably, the L-shaped handle is made of threaded steel to increase friction when rotating the front panel and improve the operability for construction workers.

[0012] The beneficial effects of this utility model are as follows: (1) It can be made from common building materials such as scrap steel plates, steel cylinders and steel bars on the construction site. It is easy to install and convenient to use.

[0018] Example like Figure 1-3 As shown, a funnel device for pouring concrete at the top of a structural column includes an L-shaped side plate 2 and a front panel 5 disposed inside the L-shaped side plate 2. The L-shaped side plate 2 and the front panel 5 are connected by a rotating shaft 4. The L-shaped side plate 2 is fixedly connected to the rotating shaft 4, and the front panel 5 is rotatably connected to the rotating shaft 4. A first angle steel 7 is welded to the outer side of the top corner of the two L-shaped side plates 2 near the template position, and a second angle steel 6 is welded to the outer side of the bottom corner of the two L-shaped side plates 2 near the template position. Two L-shaped handles 3 are welded on the front panel 5. Three threaded holes are provided on the first angle steel 7 and the second angle steel 6 for fixing the funnel device so that the device does not move during the concrete pouring process.

[0019] A hollow steel cylinder 1 is welded to the top of the first angle steel 7. The hollow steel cylinder 1 is tangential to the first angle steel 7. A detachable L-shaped screw 8 is installed inside the hollow steel cylinder 1. The L-shaped screw 8 is made of plain round steel bar. The hollow steel cylinder 1 and the rotating shaft 4 are set on the same vertical plane.

[0020] The rotating shaft 4 is fixedly set between the two L-shaped side plates 2. The front panel 5 rotates around the L-shaped side plate 2 through the rotating connection with the rotating shaft 4. The side of the L-shaped side plate 2 is an isosceles right triangle. The front panel 5 is in close contact with the L-shaped side plate 2, and the two sides of the front panel 5 that are in contact with the side plate are smooth, which facilitates the rotation of the front panel 5 later.

[0021] The front panel 5 has a sealed position and an open position during rotation. When the front panel 5 rotates to the open position, the front panel 5 moves away from the outlet of the funnel. When the front panel 5 rotates to the sealed position, the front panel 5 closes the outlet. The rotation range of the front panel 5 is between the position close to the inclined side of the L-shaped side plate 2 and the position parallel to the support template.

[0022] The edge of the L-shaped side plate 2 is provided with protrusions 9 to fix the position of the front panel 5 when it is open. The L-shaped handle 3 is made of threaded steel to increase friction when rotating the front panel 5 and improve the operability of the construction personnel. The L-shaped screw 8 is made of plain round steel bar to reduce friction when moving the L-shaped screw 8 and make it easier for the construction personnel to operate.

[0023] Working principle: When using this device to pour concrete, first firmly fix the device to the formwork, then open the front panel 5 to its maximum angle using the L-shaped handle 3. Next, apply a release agent to the inside of the device. Before pouring concrete, calculate the concrete volume in advance, then pour the concrete. When the concrete volume reaches the target value, rotate the front panel 5 using the L-shaped handle 3 to close the pouring opening. At this point, the height of the front panel 5 exceeds the height of the hollow steel cylinder 1. Then, pass the L-shaped screw 8 through the two hollow steel cylinders 1 to lock the front panel 5 in place, preventing it from opening freely and ensuring the concrete fills the top of the structural column. After the concrete reaches a certain strength, open the front panel 5. Due to the design of the front panel 5, no corbel phenomenon will occur after the concrete has solidified, eliminating the need for secondary chiseling after pouring. This simplifies the construction process, improves construction efficiency, reduces material waste, and saves construction costs.

[0024] Therefore, the present invention provides a casting funnel device for the top of a structural column with the above-mentioned structure, which can avoid secondary chiseling, simplify the construction process, improve construction efficiency, reduce material waste, and lower construction costs.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
