Description

Technical Field

[0001] The invention belongs to the technical field of waterproofing of wall bushings, and particularly relates to a waterproofing construction method for strengthening the waterproofing wing plate portion of a wall bushing. Background Art

[0002] Wall bushings are primarily used in basement construction. Whether rigid or flexible, they all have a key component: the waterproof wing ring. These wing rings are crucial. During installation, they are embedded directly into the wall, creating a tighter connection between the waterproof bushing and the wall stop, ensuring a more stable and secure fit, preventing leaks between the bushing and the wall stop.

[0003] During production, the first step is to select the desired location for the wing ring. The wing ring is then placed on the sleeve at the specified location. The spot welding is then used to secure the wing ring. The sleeve and wing ring are then welded together, ensuring a uniform weld. During the welding process, long pauses are not permitted to prevent uneven heat from causing localized deformation of the pipe.

[0004] Reference document CN106812324A describes a method for adding wall sleeves to basement exterior walls, using waterproofing strips to achieve a waterproof seal. However, because the structure involves reinforcing secondary pouring to prevent water seepage, no changes are made to the wing rings. Furthermore, secondary pouring can still easily cause cracking and water seepage in basement concrete components, especially cracking on the water-facing concrete components, which can halve the effectiveness of traditional waterproof wing rings. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the technical problem that the concrete at the connection of the wall sleeve is easily impacted by pouring and thus fails to be poured properly by adopting a multi-layer waterproof structure.

[0006] In order to solve the above technical problems, the inventors have come up with the technical solution of the present invention through practice and summary. The present invention discloses a waterproof construction method for strengthening the waterproof wing plate portion of the wall sleeve, comprising the following steps:

[0007] Step 1: Welding steel plates

[0008] Install the wall sleeve in the waterproof opening. The wall sleeve includes a main pipe and a wing ring. There are multiple sets of main pipes. Check whether the material and specifications of the wall sleeves entering the site meet the design drawings and specifications. After passing the inspection, weld steel plates along the side edges of the wing rings. The thickness of the steel plates should not be less than that of the wing rings, and the width of the steel plates should not be less than 3cm. The welding method is double-sided full welding.

[0009] Step 2: Welding the main reinforcement of the component to the wing ring

[0010] After temporarily fixing the wall sleeve at the designated position in the design drawing, use short steel bars to weld it to the wing ring and the main reinforcement of the component, and there should be no less than 3 welding points on each short steel bar;

[0011] Step 3: Install the hole reinforcement and check

[0012] After the wall sleeve is reinforced, install the hole reinforcement outside the waterproof hole and weld it to the main reinforcement of the component. Then install the stirrups inside the waterproof hole and check whether the hole reinforcement and stirrups are properly installed to ensure the bearing strength of the hole reinforcement.

[0013] Step 4: Apply anti-rust paint and waterproof coating to the wall casing

[0014] After the installation and reinforcement of the wall sleeve is completed, the surface is cleaned, and then the surface of the wall sleeve and the wing ring is painted with anti-rust paint. After the anti-rust paint solidifies, waterproof paint is applied to form a triple waterproof effect;

[0015] Step 5: Pour concrete

[0016] After all the above work is completed, you can pour concrete and strengthen the concrete vibration around the wall sleeve to ensure that there is no honeycombed surface or missing reinforcement in the concrete around the wall sleeve.

[0017] In a further technical solution, the cross section of the steel plate is suitable for being inclined toward one side of the water-stopping direction.

[0018] In a further technical solution, short steel bars are provided on both sides of the wing ring, with four groups provided on each side and distributed in a rectangular shape.

[0019] In a further technical solution, an external closing member is installed on the outside of the stirrup, and the external closing member includes two groups of movable splints, which are respectively connected to the top of the stirrup.

[0020] In a further technical solution, the external closing member includes an external connecting plate, which is provided in two groups and has a connecting port installed on the top. A connecting rod is installed between the connecting ports, and the connecting rod is a threaded rod. The movable splint includes a connecting portion, which is suitable for sliding on the connecting rod, and the connecting rod is suitable for passing through the main reinforcement of two groups of adjacent components.

[0021] In a further technical solution, the outer connecting plate is a thin-walled plate with a thickness of 2 to 3 mm.

[0022] Compared with the prior art, the present invention can achieve the following technical effects:

[0023] Compared with the prior art, the present invention increases the waterproof surface of the wing ring toward the water-stopping direction in order to achieve a water-stopping effect, and after the wall sleeve and the main reinforcement of the component are installed, the surface of the sleeve and the wing ring is painted with waterproof paint to form a triple waterproof effect. By adopting the above technical solution, the wall sleeve constructed through the above steps has an increased waterproof area and water-stopping direction due to the addition of the wall sleeve wing ring, and the waterproof paint is applied to the surface of the wall sleeve. Therefore, even if the wall sleeve of the water-facing concrete component is cracked, water will not easily seep in. The waterproof surface and water-stopping direction of the wing ring form a water-stopping effect similar to that of a water-stopping steel plate. BRIEF DESCRIPTION OF THE DRAWINGS
