Description

Technical Field

[0001] This application pertains to the field of building construction, specifically to the renovation of ground structures in old residential communities. Background Technology

[0002] The renovation of old residential communities is an important project for improving people's livelihoods, aiming to enhance the living environment and community functions. During the renovation, it is often necessary to add sports flooring near the existing tiled floors to meet residents' fitness needs. However, existing technologies have the following problems in the construction of such multi-material flooring connections: Existing technologies typically use simple butt joints or simple separators to handle the junctions of different flooring materials, lacking reliable boundary fixing and protection structures. After the sports flooring is laid, due to its certain elasticity and deformation characteristics, it is easy to exert pressure or displacement on adjacent rigid surfaces (such as floor tiles or stone thresholds), resulting in arching, cracking, or widening of gaps at the junction.

[0003] The existing construction sequence and structural layers are unclear. Especially in the area where the threshold stone and sports flooring meet, the elevation is often out of control, waterproofing fails, or the edges are uneven due to overlapping procedures and inaccurate boundary positioning, which affects the overall flatness and aesthetics.

[0004] There is a lack of edge finishing systems suitable for the site conditions of old residential areas that combine the functions of partitioning, support, and decoration. Traditional methods often use cement mortar edging or simple metal strips. The former has poor durability and is easily damaged, while the latter is not firmly fixed and cannot adapt to the coordinated deformation of the original ground structure and the newly constructed sports ground.

[0005] Therefore, there is a need for a floor renovation method that has a clear structure, orderly construction, can effectively separate different floor materials, and ensures a flat and stable interface. Utility Model Content

[0006] The purpose of this utility model is to provide a ground renovation structure for old residential areas, and to provide a sports ground that can be constructed within the community, such as at the junction of a pavilion and the indoor or outdoor ground, so as to increase residents' exercise space and improve their happiness.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: The renovation structure for the ground of an old residential area is characterized by: including a floor tile construction structure, a stone threshold construction structure, and an indoor sports flooring construction structure that are connected in sequence. The top surfaces of the floor tile construction structure, the stone threshold construction structure, and the indoor sports flooring construction structure are flush. A retaining structure is provided between the stone threshold construction structure and the indoor sports flooring construction structure. The retaining structure includes galvanized carbon steel angle brackets, expansion bolts for fixing the galvanized carbon steel angle brackets to the building floor slab, and metal edge strips. The metal edge strips are attached to the surface of the upright plate facing the galvanized carbon steel angle brackets and the indoor sports flooring construction structure.

[0008] More preferably, the floor tile construction structure includes, from bottom to top, an interface agent, C15 concrete, DS mortar leveling layer, DAT mortar bonding layer, and floor tiles, which are sequentially arranged on the building floor slab.

[0009] Furthermore, the construction structure of the stone threshold includes, from bottom to top, two layers of C15 concrete, two layers of DS mortar leveling layer, two layers of DAT mortar bonding layer, and a 20mm thick stone threshold, which are sequentially installed on the building floor slab. The top surface of the vertical plate of the galvanized carbon steel angle bracket is flush with the top surface of the two layers of DS mortar leveling layer.

[0010] Furthermore, the construction structure of indoor sports flooring includes, from bottom to top, three layers of C15 concrete, one layer of neat cement slurry, one layer of construction adhesive cement slurry, one layer of DS mortar waterproofing layer, one layer of DSL mortar base layer, one layer of composite polyvinyl chloride surface layer, and the sports flooring, which are sequentially installed on the building floor slab.

[0011] In addition, the bottom surface of the metal edge strip is located on the top surface of the plain cement slurry.

[0012] More preferably, the thickness of the DS mortar leveling layer is 25mm, and the thickness of the DS mortar waterproof layer is 20mm.

[0013] Compared with the prior art, this utility model has the following features and beneficial effects: This application adopts a technical solution of setting up a retaining structure composed of galvanized carbon steel angle brackets, expansion screws and metal edge strips between the stone threshold construction structure and the indoor sports floor construction structure. It has the technical advantages of clear demarcation, rigid positioning and prevention of lateral disturbance of the sports floor layer, and solves the technical problem of easy arching and cracking at the junction of different floor materials due to material deformation differences.

[0014] This application adopts a technical solution that first constructs galvanized carbon steel angle brackets with a retaining edge structure, making the top surface of the vertical plate flush with the top surface of the DS mortar leveling layer. This solution has the technical advantage of providing accurate elevation benchmarks and boundary support for the construction of stone thresholds and sports flooring, and solves the technical problems of chaotic construction sequence and difficulty in elevation control at the junction.

[0015] This application adopts a technical solution of setting a DS mortar waterproof layer in the construction structure of indoor sports flooring and controlling its thickness to 20mm. It has the technical advantages of effective moisture prevention and enhanced floor durability, and solves the technical problems of interlayer bonding failure and mold growth caused by water seepage in the base layer in sports flooring areas.

[0016] This application adopts a technical solution that attaches and fixes a metal edge trim strip to a galvanized carbon steel corner bracket plate, with its bottom surface located on the top surface of a layer of plain cement slurry. This solution has the technical advantages of firm edge trim, straight edges, and both decorative and protective functions, and solves the technical problems of traditional edge trim methods being prone to loosening, not resistant to impacts, and having poor aesthetics.

[0017] This application adopts a seamless construction technology that ensures the top surfaces of floor tiles, stone thresholds, and sports flooring are flush. This technology has the advantages of enabling barrier-free passage and ensuring the overall flatness and aesthetics of the ground. It also solves the technical problems of safety hazards and visual incoordination for the elderly caused by differences in ground level during the renovation of old residential areas.

[0018] This application adopts a technical solution with clearly defined and controllable material systems for each structural layer (such as a 25mm DS mortar leveling layer and a 20mm DS mortar waterproof layer). It has the technical advantages of high standardization of construction and convenient quality control, and solves the technical problems of material waste and unstable performance caused by arbitrary on-site thickness adjustment.
