Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a concrete partition for casting beams and columns. Background Technology

[0002] In building construction, beams and columns are typically poured using concrete of different grades. Therefore, during pouring, it is necessary to isolate the beam-column joints, pouring high-strength concrete first, followed by low-strength concrete, to avoid mixing different grades of concrete. Currently, the most commonly used insulated barrier consists of an airbag and an air nozzle. During construction, the airbag needs to be placed inside a reinforcing mesh in a deflated state. The reinforcing mesh generally includes main bars arranged along the beam direction and stirrups connecting the main bars. Due to the small spacing between adjacent main bars, it is not easy to place the airbag at the bottom of the reinforcing mesh. Utility Model Content

[0003] The purpose of this utility model is to provide a concrete partition for casting beams and columns.

[0004] This utility model is achieved through the following measures: a concrete partition for casting beams and columns, including an air bladder and an air nozzle set at the center of the top of the air bladder, characterized in that upper and lower retaining rings are fixedly set on the outer wall of the air bladder away from the casting area. The retaining ring has an opening for placing a reinforcing rib, and the opening faces the main rib adjacent to the airbag.

[0005] Furthermore, the width of the opening is generally smaller than the outer diameter of the reinforcing rib, and the reinforcing rib is fixed inside the retaining ring by the elastic deformation of the retaining ring.

[0006] Furthermore, threaded sections are fixed at both the upper and lower ends of the reinforcing rib, and threaded limiting rings are provided on the threaded sections and on the outside of the retaining ring.

[0007] Furthermore, the retaining ring is made of plastic. The plastic material provides elastic deformation, allowing it to securely hold the reinforcing rib and prevent it from falling off.

[0008] Furthermore, the reinforcing bar is provided with several horizontal bars at intervals along the axial direction, and the length of the horizontal bars is shorter than the distance between two adjacent main bars.

[0009] Furthermore, the reinforcing ribs and horizontal ribs are made of metal, such as steel.

[0010] The method of using the concrete partition for cast beams and columns according to this utility model is as follows: First, assemble the airbag with the reinforcing rib in the uninflated state. Insert the reinforcing rib into the opening of the retaining ring. Since the opening width is smaller than the outer diameter of the reinforcing rib, the retaining ring will elastically deform and thus clamp the reinforcing rib, ensuring that the reinforcing rib is fixed to the outer wall of the airbag (if there is a threaded limit ring, it can be tightened and fixed through the threaded limit ring).

[0011] Because of the reinforcing bars, the airbag can be easily placed within the steel mesh at the beam-column joint along with the reinforcing bars, keeping the reinforcing bars away from the area to be poured. Inflation is done through a nozzle at the top of the airbag, causing it to expand and fit tightly against the steel mesh, forming an effective concrete partition. After inflation, the airbag can withstand the pressure of concrete pouring, ensuring that different grades of concrete do not mix. The reinforcing bars and horizontal reinforcement bars, being away from the area to be poured, can withstand some of the concrete pressure, preventing excessive deformation of the airbag and affecting the partition effect. After pouring, the gas in the airbag is released, causing it to contract, and the reinforcing bars and airbag can be removed.

[0012] The beneficial effects of the technical solution provided by this utility model embodiment are as follows: Reinforcing ribs are provided on the outer wall of the airbag, providing rigid support and making it easier for the airbag to be inserted into the narrow space between adjacent main ribs, overcoming the disadvantage of difficulty in placing the airbag in a deflated state in the prior art; the reinforcing ribs and horizontal ribs can block the airbag, preventing excessive deformation when subjected to concrete pressure. The opening of the retaining ring for fixing the reinforcing rib faces the main rib, preventing the reinforcing rib from detaching from the retaining ring under stress. After the partition is removed, the airbag, retaining ring, and reinforcing ribs can all be recycled and reused, reducing material waste and conforming to the concept of green construction.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. Of course, the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0017] See Figures 1-4 A concrete partition for casting beams and columns includes an airbag 1 and an air nozzle 8 located at the center of the top of the airbag 1. The feature is that upper and lower retaining rings 2 are fixedly installed on the outer wall of the airbag 1 away from the casting area. The retaining ring 2 has an opening 201 for placing the reinforcing bar 3, and the opening 201 faces the main reinforcing bar 6 adjacent to the airbag 1.

[0018] The width of the opening 201 is generally smaller than the outer diameter of the reinforcing rib 3. The reinforcing rib 3 is fixed in the retaining ring 2 by the elastic deformation of the retaining ring 2.

[0019] Both ends of the reinforcing rib 3 are fixed with threaded sections, and threaded limiting rings 4 are provided on the threaded sections and on the outside of the retaining ring 2.

[0020] The retaining ring 2 is made of plastic. The plastic material provides elastic deformation and allows it to securely hold the reinforcing rib 3 in place, preventing it from falling off.

[0021] The reinforcing bar 3 is provided with several horizontal bars 5 at intervals along the axial direction, and the length of the horizontal bars 5 is shorter than the distance between two adjacent main bars 6.

[0022] The reinforcing ribs 3 and horizontal ribs 5 are made of metal, such as steel.

[0023] The method of using the concrete partition for cast beams and columns according to this utility model is as follows: First, assemble the airbag 1 with the reinforcing rib 3 in the uninflated state. Insert the reinforcing rib 3 into the opening 201 of the retaining ring 2. Since the width of the opening 201 is smaller than the outer diameter of the reinforcing rib 3, the retaining ring 2 undergoes elastic deformation, thereby clamping the reinforcing rib 3 and ensuring that the reinforcing rib 3 is firmly fixed to the outer wall of the airbag 1 (when there is a threaded limiting ring 4, it can be tightened and fixed by the threaded limiting ring 4).

[0024] Because of the fixing of the reinforcing bars 3, the airbag 1 can be easily placed inside the steel mesh (composed of main bars 6 and stirrups 7) at the beam-column joint along with the reinforcing bars 3, with the reinforcing bars 3 away from the area to be poured. Air is inflated into the airbag 1 through the air nozzle 8 at the top, causing the airbag 1 to expand and fit tightly against the steel mesh, forming an effective concrete partition. After inflation, the airbag 1 can withstand the pressure during concrete pouring, ensuring that concrete of different grades does not mix. The reinforcing bars 3 and horizontal bars 5, being away from the area to be poured, can withstand some of the concrete pressure, preventing excessive deformation of the airbag 1 and affecting the partition effect. After pouring, the gas in the airbag 1 is released, causing the airbag 1 to contract, and the reinforcing bars 3 and the airbag 1 are removed.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
