Description

Technical Field

[0001] The present invention belongs to the technical field of building drainage, and in particular relates to a zero-drop plate type integrated pipe well drainage system and a construction method thereof. Background Art

[0002] In existing building drainage technology, the traditional same-floor drainage system usually requires lowering the floor or raising the bathroom surface to achieve pipe layout, which leads to complex construction, long cycle, low space utilization, and poor adaptability to the renovation of existing building structures. In addition, the following problems are common in the renovation of old houses: ① Lack of a unified solution for pipe well reconstruction: Existing prefabricated pipe technology has not been optimized for the characteristics of old buildings, making it difficult to achieve rapid installation and subsequent maintenance; ② Complex construction and low efficiency: Traditional pipeline installation needs to be carried out inside the building, which takes up a large space and requires multiple adjustments to the management position. The construction process requires a lot of on-site cutting and welding, which is cumbersome and difficult to control quality; ③ Large space occupation: lowering the floor or raising the surface will reduce the indoor net height and affect the user experience; ④High risk of water leakage: The pipeline interface is not sealed enough, which may lead to leakage due to construction errors.

[0003] In view of the above problems, the existing technology has not yet provided an efficient modular solution that can not only achieve zero-drop slab same-floor drainage but also adapt to the renovation of old buildings. Therefore, an integrated, factory-prefabricated, and on-site fast-assembled drainage system is urgently needed to improve construction efficiency, save space, and reduce maintenance costs. Summary of the invention

[0004] The present invention provides an integrated, factory-prefabricated, on-site quickly assembled drainage system, a zero-drop plate integrated pipe well drainage system and a construction method thereof, which improves construction efficiency, saves space and reduces maintenance costs.

[0005] The present invention provides a zero-drop plate integrated pipe well drainage system, which adopts the following technical solutions: A zero-drop plate integrated pipe well drainage system, comprising: A steel frame structure, wherein the steel frame structure is arranged on the outside of the building wall, and a plurality of pipe clamps are fixed on the steel frame structure, and a stop rubber ring is arranged on the inner side of the pipe clamp; An assembled drainage pipe module, the assembled drainage pipe module includes a sewage riser, a wastewater riser and a ventilation riser, the sewage riser and the wastewater riser are respectively spliced ​​end to end through a three-way joint, the sewage riser, the wastewater riser and the ventilation riser are penetrated in the stop rubber ring of the steel frame structure, the sewage riser and the wastewater riser are installed at the interface of the sewage riser and the wastewater riser, and the sewage riser and the wastewater riser are provided with an inspection port; the third interface of the three-way joint is connected to the drainage branch pipe of each floor, and the drainage branch pipe is located above the floor plate; A protective plate, which is integrated on the outside of the steel frame structure and is used for external protection and waterproofing of the assembled drainage pipe module; The drainage system is produced by modular prefabrication and assembled and installed on site to achieve same-floor drainage of zero-drop slabs in the renovation of old houses.

[0006] Preferably, the protective plate is a galvanized plate.

[0007] Preferably, the sewage riser, wastewater riser and ventilation riser are made of HDPE or HTPP material.

[0008] Preferably, the sewage riser and the wastewater riser are connected to the ventilation riser via an H-tube, and the ventilation riser passes through a stop rubber ring.

[0009] Preferably, a waterproof steel casing is arranged between the drainage branch pipe and the building wall, and the gap between the waterproof steel casing and the drainage branch pipe is filled with flame-retardant dense material and waterproof paste.

[0010] Preferably, the steel frame structure is a detachable frame structure, which is matched with the assembled drainage pipe through preset connection nodes.

[0011] Preferably, each floor slab is provided with a water-sealed floor drain and a rear outlet of the toilet. The water-sealed floor drain is connected to the three-way joint of the wastewater riser through a drainage branch pipe and a water trap arranged on the outside of the building wall. The rear outlet of the toilet is connected to the three-way joint of the sewage riser through a drainage branch pipe, so as to realize same-floor drainage of the zero-drop floor.

[0012] The present invention also provides a construction method of a zero-drop plate integrated pipe well drainage system, comprising the following steps: (1) On-site measurement and BIM modeling: Conduct on-site dimension measurements of building walls, floor slabs, and drainage requirements, design the three-dimensional layout of pipe wells and drainage systems using BIM software, determine the installation locations of steel frame structures, sewage risers, wastewater risers, ventilation risers, and inspection ports, and generate construction instructions; (2) Modular prefabrication: prefabricate the assembled drainage pipe modules in the factory according to the BIM model, including sewage riser, wastewater riser, ventilation riser, tee joint, expansion joint and inspection port, and pre-install the pipe clamp and stop rubber ring; Prefabricated steel frame structural components, which include a detachable frame structure and pre-set connection nodes; Prefabricated galvanized sheet protection plate with reserved access door or inspection opening; (3) On-site assembly and installation: fix the steel frame structure to the outside of the building wall; Fix the prefabricated sewage riser, wastewater riser and ventilation riser on the steel frame structure through pipe clamps and stop rubber rings, and install expansion joints at the interfaces of sewage riser and wastewater riser; Connect the drainage branch pipes on each floor to the sewage riser and wastewater riser through three-way joints, and connect them to the water-free floor drain and the back outlet of the toilet; A waterproof steel casing is installed at the connection between the drainage branch pipe and the building wall, and the gap is filled with flame-retardant dense material and waterproof paste; Install galvanized sheet protection to form a closed pipe well structure; (4) System acceptance test: perform pressure test on the drainage system to check the tightness of the pipes and the displacement adaptability of the expansion joints; Check and accept the waterproofness of the protective plate and the stability of the steel frame structure; Ensure that the drainage system can achieve the same-floor drainage function of the zero-drop slab without the need to sink or raise the floor slab.

[0013] Beneficial effects of the present invention: (1) Zero drop slab design: The drainage branch pipe is connected to the sewage riser and wastewater riser by laying on the wall or surface layer, avoiding dropping the slab or raising the surface layer. This not only significantly reduces the damage to the building structure during construction, but also maximizes the retention of indoor space and increases the utilization rate of indoor space.

[0014] (2) Modular and efficient construction: Steel frames, sewage risers, wastewater risers, ventilation risers, protective panels and other components are prefabricated in the factory and only require simple assembly on site, greatly shortening the construction period.
