Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring equipment, in particular to a flaring auxiliary tool for pouring concrete in a small-diameter steel pipe column. Background Art

[0002] With the widespread application of steel-concrete structures, steel pipe columns are an important component of them, and their construction quality is directly related to the stability and safety of the overall structure. In the construction process of steel pipe columns, concrete pouring is a crucial link. However, due to the smaller inner diameter of small-diameter steel pipe columns, the reserved pouring openings of their stiffening plates will be smaller, resulting in problems such as great construction difficulty and extremely inconvenient pouring during the concrete pouring process in the column. The traditional method of concrete pouring generally uses a tower crane to lift the hopper. This method not only consumes a lot of manpower, machinery and time resources, but also poses a major safety hazard because the hopper may be subjected to eccentric force during the process of concrete entering the hopper.

[0006] Furthermore, an arc-shaped fitting portion for fitting with the side of the hopper is provided on the top of the fixing cylinder.

[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, an embodiment of the utility model proposes a flaring auxiliary tool for pouring concrete in a small-diameter steel pipe column, comprising: a hopper 1, a discharge pipe 2 and a fixed cylinder 3. The hopper 1 is conical, and the discharge pipe 2 is connected to the bottom of the hopper 1. The fixed cylinder 3 is fixed at the bottom of the hopper 1. The storage pipe is located in the fixed cylinder 3. The fixed cylinder 3 is used to be sleeved on the steel pipe column to be poured. At least two locking components are provided on the fixed cylinder 3 for locking it to the steel pipe column.

[0019] The utility model arranges a locking assembly on the side wall of the fixed cylinder 3 to fix the fixed cylinder 3 and the hopper 1 on the fixed cylinder 3 on the steel pipe column to be poured, thereby preventing the hopper 1 from shifting due to force during the pouring process, and also realizes the expansion assistance for pouring concrete in the small-diameter steel pipe column, which not only improves the pouring efficiency and quality, reduces the construction cost and safety risk, but also has the advantages of simple structure, easy operation, wide application range, and repeated recycling, and has good practicality and promotion value.

[0020] By providing a fitting portion 4 at the top of the fixed cylinder 3, the fixed cylinder 3 can be well fitted with the outer wall of the hopper 1. Furthermore, an annular edge 5 is provided at the top of the hopper 1 to prevent concrete from spilling out of the top of the hopper 1, making it easier to add concrete into the hopper 1.

[0021] As an example, Figure 2 as well as Figure 3 As shown, the locking assembly includes: a sleeve 6 and a locking screw 7. The sleeve 6 is embedded in the side wall of the fixing tube 3. The locking screw 7 passes through the sleeve 6 and is inserted into the fixing tube 3. The locking screw 7 is threadedly connected to the sleeve 6.

[0022] Furthermore, in order to facilitate the fitting of the locking screw 7 to the side wall of the steel pipe column, a locking seat 8 is fixedly provided at the end of each locking screw 7 located at one end in the fixing tube 3. The locking screw 7 only needs to be rotated to make the locking screw 7 move closer to the steel pipe column to be cast, so that the locking seat 8 at the end of the locking screw 7 is finally made to fit tightly with the steel pipe column. Preferably, the side of the locking seat 8 that fits tightly with the steel pipe column can also be designed as an arc surface, thereby increasing the contact area between the locking seat 8 and the steel pipe column and improving the clamping effect of the locking seat 8.

[0023] As another example, Figure 4 As shown, each of the locking components includes: a sliding column 9, a spring 11 and a clamping seat 10, one end of the sliding column 9 is horizontally inserted into the fixed cylinder 3, and the sliding column 9 is slidably connected to the fixed cylinder 3, the clamping seat 10 is fixed to the end of the sliding column 9 located in the fixed cylinder 3, the spring 11 is fixed between the clamping seat 10 and the inner wall of the fixed cylinder 3, and a locking member is provided on the side wall of the end of the sliding column 9 located outside the fixed cylinder 3. Specifically, the locking member includes: an extension rod 12 and a fixing screw 13, the extension rod 12 is fixed On the side wall of the sliding column 9, the extension rod 12 is detachably connected to the side wall of the fixed tube 3 through a fixing screw 13, and the fixing screw 13 is threadedly connected to the side wall of the fixed tube 3; by arranging a spring 11 between the clamping seat 10 and the inner wall of the fixed tube 3, the clamping seat 10 is kept in close contact with the side wall of the steel pipe column under the elastic force of the spring 11, and at the same time, by rotating the fixing screw 13, the fixing screw 13 can drive the extension rod 12 to move closer to the fixed tube 3, so that the sliding column 9 pushes the clamping seat 10 to further clamp the steel pipe column.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
