Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a method for installing prefabricated bathroom external components. Background Technology

[0002] In the construction industry, the installation of prefabricated bathroom fixtures has always been a crucial step. However, with the development of the construction industry and the increasing demands for building safety and practicality, traditional installation methods for prefabricated bathroom fixtures have gradually revealed numerous problems.

[0003] In special locations such as hospitals, the safety hazards in restrooms are particularly prominent. The slippery environment makes users prone to accidents, and traditional installation methods cannot meet the special safety requirements of hospitals. At the same time, the sturdiness of traditional prefabricated wall panels is significantly insufficient, and their strength is insufficient to withstand large loads. This makes it easy for traditional external components to fall off or loosen, which not only affects safety but also damages the wall panels.

[0004] During construction, traditional methods rely on complex procedures such as on-site drilling, connection, and fixing. This not only increases the difficulty of construction but also leads to low efficiency and extended construction periods. Moreover, on-site drilling can easily damage tiles, and the hole size error is relatively large, making it difficult to guarantee installation accuracy. In addition, traditional installation methods have high requirements for the material of the secondary structure wall, making them unsuitable for various types of walls such as concrete structural walls, red brick walls, ALC panel walls, and light steel keel partition walls, thus greatly limiting their applicability.

[0005] In response to the problems mentioned above, there is an urgent need for a new installation method to address the shortcomings of traditional methods in terms of safety, construction efficiency, installation accuracy, and applicability, so as to meet the needs of modern building construction.

Detailed Implementation

[0028] This specific implementation adopts the following technical solution: a method for installing prefabricated bathroom external components, including the following steps: A. Preliminary Technical Preparations Based on the project design drawings and relevant specifications, a detailed construction plan and detailed design guidelines were prepared. The actual dimensions of the secondary structural walls and bathrooms were verified on-site. The drawings were further refined, especially for special areas such as the safety shower bench and washbasin. After completion, all parties were notified to inspect and confirm the material samples. The refined drawings were then sent to the factory for technical briefing and production coordination. The factory produced the prefabricated bathroom external components according to the confirmed cutting and production drawings and material samples, strictly producing them in batches. After production, batch sampling inspections and in-factory assembly tests were conducted to ensure component quality. Components were delivered to the project site in batches and properly handed over according to the on-site construction progress. B. Surveying and Setting Out Draw a one-meter line from the one-meter line control point of the secondary structure, and accurately lay out the finished surface control line in the bathroom. The line is clear and the error is controlled within ±1mm. C. Installation of a safety shower seat / stool Fire-retardant boards are used to reinforce the wall panel installation area, and 8mm galvanized steel plates are attached to the inner and outer sides of the secondary structure wall. The bench is then connected with M8 stainless steel bolts and secured to the wall panel and wall as a whole with spring-loaded fastening sleeves. D. Installation of prefabricated wall panel washbasins Structural Design: The prefabricated wall panel washbasin installation structure consists of prefabricated wall panels, mounting frames, and fixing bolts. The installation and fixing structure uses a reinforcing plate with bent reinforcing back ribs to improve stability. The reinforcing plate has main connection holes and pre-fixing holes, which divides the installation into pre-fixing and fixing stages, improving the accuracy of installation dimensions and ensuring installation strength and efficiency. Installation and fixing technology of bent reinforced back ribs: In the preparation stage, when installing the washbasin in the prefabricated wall panel, first fix the bent reinforced back ribs. The reinforced plate is equipped with main connection holes and pre-fixing holes, which are perpendicular to the installation position of the mounting frame. The washbasin installation position is reinforced during the early design of the prefabricated wall panel. During installation, ensure that the reinforced plate and the mounting frame are installed to the position of the local reinforced flame-retardant plate. In the pre-fixing stage, the reinforced plate is first pre-fixed to the prefabricated wall panel with screws and pre-fixing holes. Then, the fixing bolts are passed through the main connection holes, and the prefabricated wall panel is installed in the corresponding position. The pre-drilled holes on the mounting frame are initially connected with the fixing bolts. The mounting frame is composed of horizontal galvanized angle steel and vertical galvanized angle steel connected with fixing bolts. In the fixing stage, the washbasin is installed on the mounting frame. After leveling and adjusting the height, the fixing bolts are tightened, and hardware accessories such as washbasin and faucet are installed. E. Installation of wall-mounted components The "L"-shaped connection of the reinforcing plate: The main installation structure of the prefabricated wall panel external connection reinforcement component is fixedly connected by the "L"-shaped connection formed by bending the two ends of the reinforcing plate at 90°. The overall installation support has high strength and the structure is safe and reliable. It works better with the reinforcing steel plate behind the building wall to better bear the force and transfer the force to the wall surface. The bent inner reinforcing plate creates a gap between the prefabricated wall panel and the building wall to achieve moisture-proof and breathable function. In addition, the fixing parts on the outer surface of the wall panel can extend the fasteners into the gap to make the outer surface decoration and the external component firmly integrated. Installation and fixing of the "L"-shaped connector reinforcement plate: The wall panel is locally reinforced at the installation position of the "L"-shaped connector and the external component according to the design drawings. The treated area is replaced with fire-retardant board instead of the original wall panel material to improve the strength of the wall panel and increase the installation stability of the external component. First, the outer surface reinforcement steel plate of the secondary structure wall is installed to the position shown in the drawings. Then, the bottom plate of the "L"-shaped connector is attached to the secondary structure wall. The outdoor reinforcement plate, the building wall and the indoor reinforcement plate are connected in sequence through the reserved connection holes using bolt assemblies to make the three connected and stable as a whole. During installation, pay attention to leveling the reinforcement plate before tightening. The outer surface of the indoor reinforcement plate is fixed to the reinforcement plate by passing self-tapping screws through the external component, tile, decorative wall panel and reinforcement plate in sequence. The self-tapping screws extend into the gap formed by the "L"-shaped connector to make the whole thing fixed to the reinforcement plate.

[0037] The invention is used as follows: It features a reasonable and simple structure, low production cost, and convenient installation. Before construction, a construction plan and detailed drawings are prepared based on the design documents. After verifying the dimensions of the secondary structure walls, specific details are added to the reinforcement parts of external components such as the safety shower bench and washbasin. The factory production end is then briefed, and the factory produces the components according to the drawings. After random sampling and testing, the components are delivered according to the schedule. Then, based on the position in the design drawings, a one-meter line is drawn from the one-meter line control point of the secondary structure, with the error controlled within ±1mm. Next, an automatic drilling machine is used to precisely drill the wall holes for the installation of the safety shower bench, the prefabricated wall panel washbasin, and the external wall components.

Finally, the external wall-mounted components are installed. "L"-shaped reinforced plates with 90° bends at both ends are bolted to the inner and outer steel plates of the secondary structure wall. The external components are fixed to the reinforced plates with tiles and wall panel self-tapping screws, forming an integrated load-bearing structure.
