AI Technical Summary
In existing public building decoration and renovation projects, the construction process of open drainage ditches is complex, the construction precision is low, which affects the appearance of the decoration and the construction efficiency is low.
A square steel structure is installed on a reinforced concrete floor slab as a shallow drainage ditch. Combined with height-adjusting screws and detachable fixed support components, the construction process is simplified, the accuracy is improved, and a stable drainage system is formed with the concrete structure through drainage sleeves.
It simplifies the construction process, improves construction accuracy and efficiency, adapts to different drainage volumes and decoration layout requirements, and enhances practicality and aesthetics.

Abstract
Claims
1. A shallow trench structure for waterproofing a floor drain of a finished floor, comprising a reinforced concrete floor provided with a floor waterproofing material on top, characterized in that: Two square steel structures are installed above the waterproof floor slab, forming a shallow drainage ditch between them. A height adjustment screw is installed below each square steel structure, with its lower end connected to the reinforced concrete floor slab. Removable fixed support components are installed on the inner sides of the two square steel structures to adjust the width of the drainage ditch. A drainage sleeve is horizontally installed on the side end of each square steel structure, communicating with the drainage ditch. A concrete structure is installed on the outer end of each square steel structure.
2. A shallow trench structure for a polished concrete floor drain according to claim 1, wherein: The square steel structure includes a square steel tube, angle brackets, and angle steel. The square steel tube is set perpendicular to the reinforced concrete floor slab. The angle brackets are connected to the bottom outer side of the square steel tube and are connected to the height adjustment screw. The angle steel is connected to the top of the square steel tube.
3. A shallow trench structure for a polished concrete floor drain according to claim 2, wherein: The steel square tube is configured as a galvanized steel square tube or a stainless steel square tube, and the end of the steel square tube is provided with a sealing plate.
4. The shallow trench drain structure for a polished floor according to claim 2, wherein: A trench cover is provided at the upper end of the square steel structure, and the trench cover is placed between the angle steel of the two square steel structures.
5. The shallow trench drain structure for a polished floor according to claim 3, wherein: The height adjustment screw includes a screw, a height adjustment nut, and a fixing nut. The angle bracket is provided with an elongated hole. The upper end of the screw is located in the elongated hole. The height adjustment nut and the fixing nut are threadedly connected to the upper end of the screw. The height adjustment nut is located below the angle bracket, and the fixing nut is located above the angle bracket. The lower end of the screw is connected to the reinforced concrete floor slab.
6. A shallow trench structure for a polished concrete floor drain according to claim 1, wherein: The height adjustment screw is equipped with a screw waterproofing system, and the screw waterproofing system is in a closed connection with the floor slab waterproofing system.
7. A shallow trench structure for a polished concrete floor drain according to claim 1, wherein: The fixed support assembly includes an inner positioning vertical rod, an upper positioning horizontal screw, a lower positioning horizontal screw, and an outer fixing plate. The upper and lower positioning horizontal screws are arranged parallel to each other, and both ends of the lower positioning horizontal screw are threaded to the inner positioning vertical rod. The inner positioning vertical rod is tightly fitted and limited to the inner side of the steel square tube. The upper positioning horizontal screw passes through the upper end of the inner positioning vertical rod, and both ends of the upper positioning horizontal screw are provided with outer fixing plates. The outer fixing plates are tightly fitted and limited to the outer side of the angle steel.
8. A shallow trench structure for a polished concrete floor drain according to claim 1, wherein: The bottom of the drainage ditch is equipped with a slope-finding structure.
9. A shallow trench structure for a polished concrete floor drain according to claim 4, wherein: The concrete structure includes a concrete layer and a floor finishing layer.
