Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete pouring device for a structural column without chiseling out a bell mouth. Background Art

[0002] The bell mouth on the structural column can increase the earthquake resistance: when pouring the structural column, the bell mouth is opened on the column body, so that the concrete can be stressed outward under the shear force, thereby increasing the earthquake resistance of the column. Convenient for steel bar bonding: The bell mouth of the column body also serves to facilitate the bonding of steel bars. The steel bars above and below the bell mouth can extend outward through the bell mouth and be poured together with the concrete, so that the steel bars and concrete are tightly bonded, improving the bearing capacity of the column. Reduce the stress concentration of concrete: The bell mouth can disperse the stress of the concrete, thereby reducing the stress concentration of the concrete and increasing the bearing capacity of the structural column.

[0003] Nowadays, construction is becoming more and more standardized. Secondary structures often involve the construction of structural columns. The bell mouths of structural column concrete pouring are mostly processed on-site with wooden formwork. Before opening the bell mouth, the position and size of the bell mouth are marked on the column, and then the bell mouth is flattened and trimmed using mechanical equipment or manual tools to ensure that it is smooth and flat so that it can better bond with the concrete. However, after pouring, the joint position needs to be chiseled, which wastes a lot of labor and materials. At the same time, the dust generated during the chiseling process will also pollute the environment.

[0004] Therefore, there is an urgent need for a device that can avoid chiseling after the construction of the structural column and recover the excess material in the bell-mouth device to avoid material waste. Utility Model Content

[0005] In view of this, the utility model provides a structural column bell mouth free concrete pouring device, which avoids the need to chisel the joint position after pouring, can recycle excess material, reduces material waste and environmental pollution, shortens the construction period, reduces labor input, and reduces construction costs.

[0006] The utility model provides a structural column bell mouth free concrete pouring device which adopts the following technical scheme:

[0007] A bell-mouth concrete pouring device for a structural column without chiseling out the bell-mouth comprises a template, a fixing plate and an inclined back plate, wherein the fixing plate fixes the inclined back plate on the template, the top of the inclined back plate is open, the end of the inclined back plate away from the template has an inclined surface, the bottom of the inclined surface is open, a sliding inclined plate is slidably provided on the inclined surface, and the sliding inclined plate can close the opening of the inclined surface.

[0008] Optionally, a vertical partition is provided on the template, and the vertical partition is used to cut concrete to make the concrete surface flat.

[0009] Optionally, a handle 1 is provided on the oblique back panel.

[0019] The following is combined with Figure 1 The utility model is described in further detail.

[0020] The utility model embodiment discloses a concrete pouring device for a structural column without chiseling out the bell mouth.

[0021] Reference Figure 1 A structural column bell-mouth-free concrete pouring device comprises a template 1, a fixed plate 2 and an inclined back plate 7. The fixed plate 2 fixes the inclined back plate 7 on the template 1. The top of the inclined back plate 7 is open, and the end of the inclined back plate 7 away from the template 1 has an inclined surface, and the bottom of the inclined surface is open. A sliding inclined plate 9 is slidably provided on the inclined surface. The sliding inclined plate 9 can close the opening of the inclined surface. After the sliding inclined plate 9 slides up and down, a hole can be formed to release the residual concrete for recycling.

[0022] The device can be processed on site and can be reused. The template 1 is used as the installation foundation, and a wooden template 1 can be used. The wooden template 1 is provided with a grouting opening, and when the structural column is cast, the excess concrete is carried into the oblique back plate 7 through the grouting opening.

[0023] The fixing plate 2 is trumpet-shaped, and angle steels are arranged on both longitudinal sides of the fixing plate 2. The angle steels are provided with fixing holes 3, and nails can be passed through the fixing holes 3 to fix the angle steels on the template 1.

[0024] A vertical partition 4 is provided on the template 1. After pouring is completed, the vertical partition 4 is moved to cut the concrete entering the inclined back plate 7 from the leakage port to make the concrete surface smooth. The vertical partition 4 can effectively cut the concrete to make the surface of the concrete cast at the trumpet position smooth, avoiding chiseling of the joint position after pouring.

[0025] The setting of the inclined back plate 7 allows the concrete to slide along the inclined surface and flow out from the opening.
