Technical Field
[0001] The utility model relates to the technical field of waterproof floors for building decoration, and specifically refers to a waterproof device for a sliding door spaced between a balcony and an interior room. Background Art
[0002] In the field of modern home decoration, the reasonable planning and aesthetic design of interior spaces are the keys to enhancing living comfort and aesthetic experience. As an important transitional area connecting the interior and exterior, the design of the balcony should not only meet functional requirements but also balance aesthetics and practicality. Due to its light weight, durability, and ease of maintenance, aluminum alloy sliding doors have become the preferred material for partitioning the balcony and interior spaces. However, with the increasing requirements for the home environment, the existing aluminum alloy sliding doors are gradually showing deficiencies in load-bearing capacity and waterproof performance.
[0003] Firstly, the balcony area is directly exposed to the external environment and is easily affected by natural factors such as rain and dust. Therefore, the waterproof structure design of the floor at the bottom of the sliding door is crucial, as it not only relates to the dryness and cleanliness of the interior environment but also directly affects the service life of the building. The existing aluminum alloy sliding doors usually adopt a single U-shaped steel plate as the support structure at the bottom. This design is already difficult to provide sufficient bearing capacity when facing the increasing weight of the door body, and it is also difficult to achieve a more ideal waterproof effect.
[0004] Secondly, as aluminum alloy sliding doors tend to be larger in size and heavier in material in design, the traditional support structure can no longer meet the needs of modern home decoration. This not only affects the use experience of the sliding door but also poses higher requirements for construction and installation.
[0005] In view of the above problems, designing an aluminum alloy sliding door waterproof device that can not only carry a heavier door body, provide high waterproof performance, but also be constructed simply and quickly has become an urgent technical problem to be solved in the current interior decoration field. Summary of the Invention
[0006] The purpose of the utility model is to provide a waterproof device for a sliding door spaced between a balcony and an interior room, which has high load-bearing capacity, good waterproof performance, and is convenient for construction, aiming at the deficiencies of the above situation.
[0007] To achieve the above object, the technical solution of the utility model is as follows: A waterproof device for a sliding door between a balcony and an interior, comprising: a structural floor slab, a balcony decorative floor, an interior decorative floor, and a sliding door. The sliding door is located between the balcony decorative floor and the interior decorative floor. Below the sliding door are provided: a supporting wooden keel, a fixed connecting piece, a supporting square steel keel, a U-shaped steel plate without a bottom surface, a steel plate connecting piece, a bottom sill platform, a top sill platform, a waterproof coating layer, and a waterproof mortar filling area. Among them, the bottom sill platform is cast on the structural floor slab, the width of the top sill platform is smaller than that of the bottom sill platform, and the top sill is cast above the bottom sill platform. During installation, the U-shaped steel plate without a bottom surface is fixed to the bottom surface of the supporting square steel keel through the steel plate connecting piece. The middle groove of the U-shaped steel plate without a bottom surface is inserted over the top sill platform, and the peripheral groove of the U-shaped steel plate without a bottom surface is inserted over the bottom sill platform. A waterproof mortar filling area with a triangular cross-section is cast on the step formed between the supporting square steel keel, the top sill platform, and the bottom sill platform. The waterproof coating layer is coated on the connected supporting square steel keel, waterproof mortar filling area, bottom sill platform, and structural floor slab. The sliding door is pressed on the top surface of the supporting square steel keel through the supporting wooden keel, and the fixed connecting piece fixedly connects the bottom of the sliding door, the supporting wooden keel, and the top surface of the supporting square steel keel together.
[0008] Both the bottom sill platform and the top sill platform are rectangular structures.
[0009] The waterproof mortar filling area has left and right regions. The left waterproof mortar filling area is located between the balcony decorative floor and the sliding door, and the right waterproof mortar filling area is located between the interior decorative floor and the sliding door.
[0010] The waterproof coating layer has left and right regions. The left waterproof coating layer is located between the balcony decorative floor and the sliding door, and the right waterproof coating layer is located between the interior decorative floor and the sliding door.
[0011] The sliding door is a double-door structure. The supporting wooden keel includes a left supporting wooden keel and a right supporting wooden keel corresponding to the double-door panels respectively. The supporting square steel keel includes a left supporting square steel keel corresponding to the left supporting wooden keel and a right supporting square steel keel corresponding to the right supporting wooden keel.
[0012] Polyurethane foam caulking agent is filled in the gap between the left supporting wooden keel and the right supporting wooden keel.
[0013] The sliding door includes an aluminum alloy door frame and insulating tempered glass.
[0014] The balcony decorative floor sequentially includes from bottom to top: a cement mortar leveling layer, a tile adhesive layer, and floor tiles. Among them, silicone weatherproof sealant is filled between the floor tiles and the corresponding left supporting wooden keel.
[0015] The indoor decorative floor successively includes, from bottom to top: overhead wooden square support keels, a base fireproof board, a sound insulation and moisture-proof pad, and parquet floors.
[0016] After adopting the above structure, through the support of the support square steel keels, the convex-shaped steel plates without bottom surfaces, the bottom ground ridges, and the top ground ridges, the load-bearing capacity of the sliding door is greatly improved; the waterproof coating layer is coated on the support square steel keels, the waterproof mortar filling area, the bottom ground ridges, and the structural floor slab, and waterproof coating layers are provided on both sides of the sliding door, so that the accumulated water on the balcony cannot seep through from below the balcony decorative floor, ensuring the dryness of the interior; the sliding door and the support square steel keels are connected by support wooden keels, realizing the buffering of the sliding door and the fine adjustment of the installation angle. The polyurethane foam caulking agent in the gaps of the support wooden keels also has the function of enhancing waterproofing. Therefore, the utility model has the characteristics of high load-bearing capacity, good waterproof performance, and convenient construction. BRIEF DESCRIPTION OF THE DRAWINGS
