Description

Technical Field

[0001] The utility model relates to the technical field of anti-sticking of a pouring bucket in concrete pouring, in particular to an anti-sticking covering film for a pouring bucket of a self-compacting filling layer. Background Art

[0002] Self-compacting concrete is the key to the life of CRTSIII slab track structure. Due to its workability requirements, self-compacting concrete usually uses a higher amount of cementitious materials and a certain amount of viscosity enhancer in the mix design to ensure its cohesion. Traditional pouring buckets usually use a special coating method to ensure that the concrete does not stick to the tank, but its cost is high, the construction process is complicated and it cannot maintain anti-sticking properties for a long time.

[0003] In summary, the traditional method of applying special coatings to the pouring bucket is less practical, resulting in the bottom of the pouring bucket being covered with concrete residue, affecting the pouring quality of the self-compacting filling layer of the rear panel, resulting in serious waste of self-compacting concrete.

[0004] How to solve the above problems is the research focus of this program. Utility Model Content

[0005] In order to achieve the above-mentioned purpose of the utility model and to solve the above-mentioned technical problems, the utility model provides an anti-sticking covering film for a self-compacting filling layer pouring bucket.

[0006] The technical solution is as follows: the covering film is arranged on the inner wall of the pouring bucket, the covering film matches the shape of the pouring bucket, can effectively cover the inner wall of the pouring bucket, and prevent the concrete from adhering; the side wall of the pouring bucket is provided with an aluminum alloy sealing edge to provide support and reinforcement for the covering film;

[0007] A waterproof coating layer and an adhesive layer are sequentially arranged between the inner wall of the pouring bucket and the covering film. The waterproof coating layer can block moisture penetration, prevent corrosion of the pouring bucket, and extend the service life of the pouring bucket; the adhesive layer is arranged on the inner wall of the pouring bucket, and can firmly adhere the covering film to the inner wall of the pouring bucket to ensure that it does not slide or fall off during the concrete pouring process; the adhesive layer can ensure structural integrity and prevent the anti-sticking covering film from loosening or being damaged.

[0008] The side wall of the pouring bucket is provided with a plurality of evenly distributed screw holes, the aluminum alloy sealing edge is provided with screw holes matching the side wall of the pouring bucket, and the aluminum alloy sealing edge and the side wall of the pouring bucket are fixedly connected by anchor screws;

[0009] The aluminum alloy edge sealing and the covering film are fixedly connected by anchor screws.

[0010] Anchor screws are used to fix the aluminum alloy edge banding and covering film to the side wall of the pouring bucket to ensure structural firmness.

[0011] The covering film is made of HPDE waterproof board with a thickness of 3mm. HPDE waterproof board has durability and wear resistance, and can effectively prevent concrete adhesion. It can significantly reduce concrete waste and extend the service life of the anti-stick coating.

[0012] The aluminum alloy edge banding is made of 0.7 mm thick galvanized steel sheet. The galvanized steel sheet has strength and corrosion resistance, and can provide structural support and reinforcement for the aluminum alloy edge banding to prevent it from rusting or corrosion. The galvanized steel sheet can enhance the durability and service life of the aluminum alloy edge banding.

[0013] The covering film and the pouring bucket are bonded by adhesive. The adhesive can form a strong and permanent bond between the covering film and the inner wall of the pouring bucket to prevent the covering film from peeling or falling off during the concrete pouring process. The adhesive can ensure the effectiveness of the anti-stick coating and prevent concrete leakage.

[0014] The joints of the covering film are fixed by ultrasonic welding. Ultrasonic welding is used to seal the joints of the covering film to prevent concrete leakage and ensure a smooth surface. It can enhance the effectiveness of the anti-stick coating and improve the overall appearance of the pouring bucket.

[0015] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: the solution provides an anti-sticking covering film for the pouring bucket of the self-compacting filling layer, which is easy to install and use, durable, and can effectively solve the problem of residual material being contaminated on the side wall and bottom of the pouring bucket during the pouring of self-compacting concrete, resulting in insufficient pouring pressure of the subsequent pouring plate, slow flow rate, long pouring time, secondary pouring, affecting the pouring effect of the self-compacting filling layer and causing concrete waste, thereby improving the construction quality, efficiency and economic benefits; its advantages are mainly reflected in the following aspects:

[0016] (1) Significantly reduce concrete waste: The anti-stick coating effectively prevents concrete from adhering to the side walls and bottom of the funnel, reducing the amount of concrete that needs to be cleaned after each use. It can effectively reduce the waste of self-compacting concrete caused by sticking to the tank, from the original 3% loss to 1% or less, and make the concrete flow smoother, further reducing waste;

[0017] (2) Improve concrete quality: The anti-stick coating blocks the contact between concrete and the side walls and bottom of the funnel, reducing the risk of concrete segregation and defects. It can effectively reduce the friction and resistance during the pouring of self-compacting concrete, making the concrete flow smoother, ensuring uniform mixing, improving the pouring quality, and reducing the rate of plate peeling;

[0018] (3) Improve production efficiency: The anti-stick coating simplifies funnel cleaning and reduces downtime. It can effectively save time in cleaning the pouring bucket, from cleaning two plates to cleaning five plates, improving pouring efficiency and making concrete flow smoother, speeding up the filling and emptying of the funnel;

[0019] (4) Reduced labor costs: The anti-stick coating simplifies funnel cleaning, reduces worker time, and allows concrete to flow more smoothly, reducing the number of workers required to fill and empty the funnel;

[0020] (5) Significant comprehensive benefits: It can be used in a cyclical manner and saves costs. This solution improves concrete quality, increases production efficiency, and reduces labor costs in an economical way.

[0021] (6) The size of the covering film and the edge sealing of this solution can be applied to various types of pouring buckets, with strong adaptability and easy processing. BRIEF DESCRIPTION OF THE DRAWINGS
