Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a seepage-proof pre-embedded sleeve device for basement exterior walls. Background Technology

[0002] Currently, with the development of the construction industry, there are more and more buildings with basements, and the requirements for waterproofing of basement exterior walls are also very high. During construction, in conventional basement structures, through-wall sleeves are usually welded with water-stop plates or water-stop rings in the middle of the sleeve, and pre-embedded construction is carried out directly during construction.

[0003] The existing technology has the following problems:

[0004] 1. Currently, the installation of basement exterior wall sleeves is time-consuming, labor-intensive, has a high risk of leakage, and is expensive, which leads to an increase in the number of construction workers and special operation personnel and a slower work speed.

[0005] 2. Currently available basement exterior wall sleeve devices on the market are extremely prone to water seepage and leakage. Utility Model Content

[0006] The purpose of this utility model is to provide a seepage-proof pre-embedded sleeve device for basement exterior walls, in order to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pre-embedded sleeve device for waterproofing basement exterior walls, including a flange sleeve, a water-stop steel ring is provided inside the flange sleeve near the middle, a steel pipe is provided inside the flange sleeve, and a flange cover is inserted into one side of the flange sleeve.

[0008] A stud is provided at the connection between the flange cover and the flange sleeve, and a nut is threaded onto the outer surface of the stud. A flange is fixedly connected to the other side of the flange sleeve, and a water-stop rubber ring is provided on one side of the flange.

[0009] The present invention further illustrates that a rubber sealing ring is provided at the connection between the flange cover and the flange sleeve, and a PE foam board is filled between the flange sleeve and the steel pipe.

[0010] The above technical solution enhances sealing performance through the installation of rubber sealing rings. PE foam boards are used to fill the gap between the flange sleeve and the steel pipe. PE foam boards are made primarily of polyethylene resin with added foaming agents, crosslinking agents, and other additives. They possess advantages such as low density, cushioning, heat resistance, low water absorption, stable chemical properties, resistance to corrosion, good mechanical properties, toughness, flexibility, abrasion resistance, good processing performance, and ease of molding, effectively preventing leakage.

[0011] This utility model further illustrates that a low-modulus polyurethane sealant is filled between the flange sleeve and the steel pipe.

[0012] The above technical solution uses low-modulus polyurethane sealant to seal the gap between the flange sleeve and the steel pipe. Low-modulus polyurethane sealant has excellent water resistance, oil resistance, aging resistance and corrosion resistance, resulting in better water-stopping effect.

[0013] This utility model further illustrates that the outer surface of the flange sleeve is coated with a waterproof coating, and the waterproof coating is a polyurea waterproof coating.

[0014] The above technical solution involves spraying a waterproof coating on the outermost layer. Polyurea waterproof coating is a solvent-free, pollution-free, highly reactive protective coating that is a green, environmentally friendly, and elastic waterproof material that can cure quickly, further improving the water-stopping effect and preventing leakage.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] This utility model provides a seepage-proof pre-embedded sleeve device for basement exterior walls. The device, through the installation of a water-stop steel ring, forms a seepage-proof quality assurance system, offering better seepage prevention than conventional flange sleeves. It avoids increased construction costs due to maintenance. The sleeve is poured into the exterior wall along with the concrete. The steel pipe and flange sleeve are connected by a flange cover using studs and nuts, simplifying installation and reducing overall installation costs. The water-stop rubber ring on the flange further enhances the water-stopping effect, strictly preventing leakage. The rubber sealing ring increases sealing performance, preventing water leakage between the flange sleeve and the steel pipe, thus meeting the user's needs.

[0017] This utility model provides a pre-embedded sleeve device for waterproofing basement exterior walls. It utilizes a PE foam board to fill the gap between the flange sleeve and the steel pipe. PE foam board has advantages such as low density, cushioning, heat resistance, low water absorption, stable chemical properties, resistance to corrosion, good mechanical properties, toughness, flexibility, abrasion resistance, good processing performance, and easy molding, effectively preventing leakage. Low-modulus polyurethane sealant is then used to seal the gap between the flange sleeve and the steel pipe. Low-modulus polyurethane sealant has excellent water resistance, oil resistance, aging resistance, and corrosion resistance, further enhancing the waterproofing effect. Finally, a waterproof coating is sprayed on the outermost side. Polyurea waterproof coating is a solvent-free, pollution-free, highly reactive protective coating that is a green, environmentally friendly, and elastic waterproof material that cures quickly, further improving the waterproofing effect and strictly preventing leakage, meeting the user's needs.
