Description

Technical Field

[0001] This application pertains to the field of building construction, specifically to a barrier-free renovation structure for old residential building floor tiles and kitchens and bathrooms. Background Technology

[0002] In the renovation of old residential communities, the renovation of kitchen and bathroom floors is both a key focus and a challenge. Current technology typically involves the conventional approach of completely removing the existing flooring and replacing it, or performing simple waterproofing at the doorway. This approach has the following significant drawbacks: The waterproofing system is weak and discontinuous: Existing technologies have relatively simple waterproofing treatments for threshold areas, often only applying a single layer of waterproofing or simple sealing, failing to form a complete and continuous waterproofing system with the interior waterproofing layer, making this area a high-risk area for leakage.

[0003] Water accumulation and poor drainage are likely to occur: If the slope of the renovated ground is not properly made or there is a height difference at the threshold, water can easily accumulate at the entrance of the kitchen and bathroom. The water is difficult to drain to the floor drain, and long-term water accumulation will increase the risk of leakage and affect the use of the property.

[0004] Insufficient consideration of accessibility: Traditional renovations often retain or create obvious thresholds at the entrances to kitchens and bathrooms, which pose access barriers for the elderly and wheelchair users and do not comply with accessibility design principles.

[0005] Unreliable connection between old and new structures: In partial renovations, improper handling at the junction of old and new ground structures can easily lead to cracking or settlement due to differences in materials and structures, damaging the integrity of the waterproof layer.

[0006] The renovation will cause significant damage to the original structure: the overall demolition method involves a large amount of work, will disrupt residents' lives for a long time, and may cause unnecessary damage to the surrounding intact original brick structure.

[0007] Therefore, a kitchen and bathroom floor renovation solution is needed that can ensure waterproofing without any problems, allow for unobstructed passage, minimize damage to the original structure, and ensure a reliable connection between the old and new floors. Utility Model Content

[0008] The purpose of this utility model is to provide a barrier-free renovation structure for old residential floor tiles and kitchen and bathrooms, and to provide a method for constructing sunken kitchen floor tiles without changing the original floor tile structure. It has the advantages of being less prone to water accumulation and having a good water-proof effect.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: A barrier-free renovation structure for old residential building floor tiles and kitchen / bathrooms is characterized by: including the original floor tile structure, threshold stone structure, and kitchen / bathroom waterproofing construction structure. The threshold stone structure includes, from bottom to top, a dry-hardened waterproof mortar layer, a 1.2mm thick polyurethane waterproof coating layer, a DS mortar leveling layer, a 1.5mm thick polymer cement-based waterproof coating layer, a threshold stone adhesive, and a stone threshold door, all sequentially placed on the building floor slab. The kitchen / bathroom waterproofing construction structure includes, from bottom to top, an interface agent, a lightweight aggregate concrete slope layer, a 1.2mm thick polyurethane waterproof coating layer, a 20mm thick DS mortar leveling layer, a 1.5mm thick polymer cement-based waterproof coating layer, a 20mm thick DS mortar leveling layer, a 5mm thick DAT mortar bonding layer, and floor tiles.

[0010] More preferably, the slope of the stone lining above the stone door facing the kitchen / bathroom should be ≤1:10.

[0011] Furthermore, the 1.2mm thick polyurethane waterproof coating layer is inclined upwards and overlaps with the 1.2mm thick polyurethane waterproof coating layer, and the 1.5mm thick polymer cement-based waterproof coating layer is inclined upwards and overlaps with the 1.5mm thick polymer cement-based waterproof coating layer.

[0012] Furthermore, the thickness of the lightweight aggregate concrete sloping layer is greater than 30mm, and the slope towards the floor drain is not less than 0.5%.

[0013] Furthermore, the original brick structure includes, from bottom to top, an interface agent, a lightweight aggregate concrete cushion layer, a 25DS mortar leveling layer, a 5mm thick DAT mortar bonding layer, and an original brick structure, all sequentially placed on the building floor slab.

[0014] Furthermore, the area near the threshold stone structure of the original brickwork is the demolition and reconstruction area, and a waterproof layer is installed on the lightweight aggregate concrete subbase in the demolition and reconstruction area. In addition, the lightweight aggregate concrete subbase is a 60mm LC5.0 lightweight aggregate concrete subbase.

[0015] More preferably, the total thickness of the original floor tile structure is not less than 100mm, and the total thickness of the waterproof construction structure in the kitchen / bathroom is not less than 80mm.

[0016] Compared with the prior art, this utility model has the following features and beneficial effects: This application adopts a double-layer waterproofing system consisting of a dry-hardened waterproof mortar layer, a polyurethane waterproof coating, and a polymer cement-based waterproof coating in the threshold structure, and connects it diagonally upwards with the corresponding double-layer waterproofing layer in the kitchen / bathroom. This solution has the technical advantage of forming a continuous, complete, and multi-layered waterproof barrier in key leakage areas, and solves the technical problems of weak waterproofing at the traditional threshold area and easy separation from the indoor waterproofing layer, leading to leakage.

[0017] This application adopts a technical solution that designs the top surface of the stone door to slope inwards towards the kitchen / bathroom (slope ≤ 1:10). This solution has the technical advantages of eliminating the height difference between the inside and outside of the threshold, guiding water flow inwards, and achieving truly barrier-free passage. It also solves the technical problems of threshold obstruction and easy water backflow at the doorway after the renovation.

[0018] This application adopts a technical solution of setting a lightweight aggregate concrete sloping layer with a thickness of more than 30mm and sloping towards the floor drain (slope ≥ 0.5%) in the base layer of the kitchen / bathroom floor. It has the technical advantages of ensuring smooth drainage of the ground and eliminating local water accumulation, and solves the technical problems of poor drainage and long-term slippery surface caused by insufficient or uneven ground slope.

[0019] This application adopts a technical solution that designates the area near the threshold of the original brick structure as the demolition and reconstruction area, and adds a waterproof layer on the lightweight aggregate concrete cushion layer in this area. This solution has the technical advantage of strengthening the weak waterproof link at the junction of the old and new structures and preventing water from seeping into the original structure from the joint. It also solves the technical problem of hidden leakage that is prone to occur at the junction of the old and new ground in local renovation.

[0020] This application, through a technical solution that clearly limits the total thickness of the original floor tile structure to no less than 100mm and the total thickness of the kitchen / bathroom structure to no less than 80mm, has the technical advantages of ensuring that each structural layer has sufficient strength and stability and controlling the final finished surface elevation, thus solving the technical problems of insufficient bearing capacity or chaotic elevation of the ground structure after renovation.

[0021] This application adopts a technical solution using lightweight aggregate concrete as the main material for the subbase and slope-finding layer. It has the technical advantages of reducing structural load and facilitating on-site construction and slope-finding. It is particularly suitable for renovation scenarios where the load of old floor slabs is limited, and solves the technical problems of heavy self-weight and inconvenient construction when using ordinary concrete.

[0026] Example 1 A barrier-free renovation structure for old residential building floor tiles and kitchen / bathroom designs, such as... Figure 1 As shown, the structure includes the original floor tile structure 1, the threshold stone structure 2, and the kitchen / bathroom waterproofing construction structure 3. The threshold stone structure 2 includes, from bottom to top, a dry-hardened waterproof mortar layer 21, a 1.2-thick polyurethane waterproof coating 22, a DS mortar leveling layer 23, a 1.5-thick polymer cement-based waterproof coating 24, a threshold stone adhesive 25, and a stone threshold 26, all sequentially placed on the building floor slab 4. The kitchen / bathroom waterproofing construction structure 3 includes, from bottom to top, an interface agent 31, a lightweight aggregate concrete slope layer 32, a 1.2-thick polyurethane waterproof coating layer 33, a 20-thick DS mortar leveling layer 34, a 1.5-thick polymer cement-based waterproof coating 35, a 20-thick DS mortar leveling layer 36, a 5-thick DAT mortar bonding layer 37, and floor tiles 38.

[0027] The stone doorway 26 faces the kitchen / bathroom with a slope of ≤1:10. A 1.2mm thick polyurethane waterproof coating layer 2 (33) slopes upwards and overlaps with a 1.2mm thick polyurethane waterproof coating layer 1 (22). A 1.5mm thick polymer cement-based waterproof coating layer 2 (35) slopes upwards and overlaps with a 1.5mm thick polymer cement-based waterproof coating layer 1 (24). The lightweight aggregate concrete sloping layer 32 is greater than 30mm thick, with a slope towards the drain of not less than 0.5%. The original floor tile structure 1 includes tiles sequentially installed from bottom to top on the building floor slab. The interface agent 11, lightweight aggregate concrete cushion layer 12, 25DS mortar leveling layer 13, 5mm thick DAT mortar bonding layer 14, and in-situ roll 15 are on the original brick structure 1. The area near the threshold stone structure 2 is the demolition and reconstruction area. A waterproof layer 5 is provided on the lightweight aggregate concrete cushion layer 12 in the demolition and reconstruction area. The lightweight aggregate concrete cushion layer 12 is a 60mm LC5.0 lightweight aggregate concrete cushion layer. The total thickness of the original brick structure 1 is not less than 100mm. The total thickness of the kitchen / bathroom waterproof construction structure 3 is not less than 80mm.

[0028] Example 2 Based on Example 1, the construction sequence in this example is as follows: First, remove the kitchen / bathroom floor tile structure, then remove part of the original floor tile structure 1 near the kitchen / bathroom. After that, construct the demolition and reconstruction area, and proceed with the construction of the threshold stone structure 2 and the kitchen / bathroom waterproof construction structure 3 in that order. Since the threshold stone structure 2 has a slope and the elevation of the internal waterproof layer is higher than the elevation of the internal waterproof layer of the kitchen / bathroom waterproof construction structure 3, the double waterproof layers on both sides overlap each other. The waterproof layer inside the threshold stone structure 2 is horizontal and then slopes downward. The waterproof layer is constructed above the 1.2mm thick polyurethane waterproof coating 22 and bends upward to the side wall of the 25DS mortar leveling layer 13.
