Abstract
Description
Technical Field
[0001] This utility model relates to the field of washbasin technology, specifically a finished washbasin support system. Background Technology
[0002] In recent years, with the sustained and rapid development of my country's economy, the construction industry has gradually transformed towards integration and industrialization, placing higher demands on construction efficiency, assembly precision, and on-site safety. In interior decoration, especially in wet areas such as bathrooms and kitchens, the installation quality of bathroom facilities such as washbasins and sinks directly affects the user experience and overall aesthetics. Currently, traditional washbasin installation often uses on-site welding of angle iron brackets, which presents several problems: First, the angle iron needs to be cut and welded on-site, which is not only cumbersome and time-consuming but also poses significant safety hazards, such as fires caused by welding sparks and injuries from cutting operations; second, on-site processing is limited by worker skill levels and construction conditions, making it difficult to guarantee the dimensional accuracy of the brackets, easily leading to uneven installation and uneven stress on the washbasin, which can cause cracks in the countertop or loosening of the basin; furthermore, traditional angle iron brackets lack adjustment functions, cannot adapt to different sizes of countertops and basins, and cannot meet the requirements of standardized and modular components in industrialized construction, thus limiting the development of prefabricated buildings. Therefore, the industry urgently needs a washbasin support system with features such as adjustability, modularity, safety, and reliability to improve construction efficiency, ensure installation quality, and promote the industrialization of construction. Summary of the Invention
[0003] The purpose of this invention is to solve the problems mentioned in the background art by providing a finished washbasin support system.
[0004] The technical solution of this utility model to achieve the above objectives is as follows: A prefabricated washbasin support system includes a washbasin, a main frame, a secondary frame, a bracket, and a support structure, wherein the main frame, secondary frame, bracket, and support structure are located below the washbasin.
[0005] The main frame is L-shaped, and a positioning hole is opened on the side of the main frame away from the sub-frame for connecting to the wall with expansion bolts; The sub-frame is L-shaped, and its lateral end is slidably installed inside the lateral end of the main frame. The main frame and the sub-frame are fixed together by flange bolts. The bracket is bolted to the side of the sub-frame away from the main frame and is used to support the stone material on the side of the washbasin.
[0006] The supporting structure is located between the washbasin and the ground, with its upper end attached to the washbasin and its lower end attached to the ground.
[0007] Preferably, the support structure includes a U-shaped support plate, a sleeve, a threaded rod, and a wing nut. The U-shaped support plate is located at the upper and lower ends of the support structure. A sleeve is fixed on the lower U-shaped support plate, and a threaded rod is fixed on the upper U-shaped support plate. The end of the threaded rod is inserted into the sleeve, and the threaded rod is engaged with the wing nut. The wing nut is held in place at the opening of the sleeve.
[0008] Preferably, the main frame is provided with anti-mildew silicone, which is applied to the contact surface between the main frame and the washbasin.
[0009] Preferably, the bracket is provided with an elongated hole, which is opened on the bracket.
[0010] Preferably, a foam pad is provided at the contact surface between the support structure and the washbasin, and the foam pad is fixed to the support structure.
[0011] Preferably, the main frame is provided with a reinforcing rod, one end of which is fixed to the lateral position of the main frame and the other end is fixed to the longitudinal position of the main frame, forming a triangle with the main frame.
[0012] This utility model, through its structural design, utilizes the telescopic nature of the main and secondary frames, as well as the height adjustment function of the support structure under the washbasin, to flexibly adapt to countertops and basins of different sizes. This ensures installation accuracy and uniform stress distribution, effectively eliminating the risk of the basin falling due to insufficient support. Finally, the combined load-bearing structure of the main and secondary frames, along with the auxiliary support structure at the bottom of the basin, makes the overall stress distribution of the washbasin more scientific and reasonable, significantly improving the product's stability and durability. Compared to existing technologies that rely on on-site welding of angle iron brackets, which not only results in slow construction progress and generates a large amount of dust and noise, but also suffers from large dimensional errors due to manual processing, easily leading to uneven brackets and uneven stress on the washbasin, posing a risk of countertop cracking or basin loosening over long-term use, this utility model not only saves labor and shortens the construction period, but also standardizes the detailed node construction through standardized and modular design, greatly improving installation quality and reliability, and powerfully promoting the industrialization of building installation engineering.
