Guangxi Qinglong Chemical Building Materials Co., Ltd. and Guangdong Qinglong Construction Engineering Co., Ltd. have been granted national utility model patents.

Recently, the "Space-Saving Vertical Plaster Casting Frame" jointly developed by Guangxi Qinglong Chemical Building Materials Co., Ltd. and Guangdong Qinglong Construction Engineering Co., Ltd. was officially granted a utility model patent by the State Intellectual Property Office, patent number: ZL202123400430.7. The patent application was submitted on December 30, 2021, and the authorization announcement was made on June 10, 2022, marking another significant breakthrough for the two companies in the field of plaster production equipment technology.

Traditional gypsum production methods suffer from space waste.

In traditional gypsum production, gypsum molds are typically placed horizontally on the ground for pouring and molding. Workers pour the mixed gypsum slurry into the mold, seal it after pouring, and then let it stand for several days to allow the gypsum to fully solidify before removing the mold. While this horizontal production method is simple to operate, it has a significant drawback—it requires a large area and limits production scale. With increasingly scarce land resources, how to increase production capacity within limited production space has become a pressing problem for gypsum production companies.

Technological Innovation: Vertical Structure Achieves Space Saving

In response to the aforementioned industry pain points, the R&D team of Guangxi Qinglong Chemical Building Materials Co., Ltd. and Guangdong Qinglong Construction Engineering Co., Ltd.—inventors Lei Jingling, Zhang Ke, and Song Dunqing—innovatively designed a vertical casting frame structure.

This vertical plaster mold support frame mainly consists of two parts: a support frame and a spacer anti-tipping component. The support frame supports one end of multiple plaster molds, while the other end of the plaster molds is connected to the spacer anti-tipping component. The spacer anti-tipping component further includes a connecting plate and a connector. One end of the connector is movably inserted into the plaster mold, and the other end is movably connected to the connecting plate.

In practical use, the bottom of the plaster mold is supported by the ground, while the top, which is suspended, rests on a support frame. This vertical placement method allows multiple plaster molds to be poured and molded simultaneously in the vertical direction, effectively reducing the floor space occupied by the plaster molds and saving production space.

Detailed design enhances practicality and versatility

Beyond its core vertical structural design, this molding frame also demonstrates ingenuity in its details. The connecting plate features grooves, and the connectors are loosely or tightly connected to the connecting plate via fasteners (such as screws and nuts). This design allows the position of the connectors to be flexibly adjusted according to the different spacing between adjacent plaster molds, offering high versatility and adapting to the production needs of plaster molds of various specifications.

The connectors can be made of square or round steel pipes, making the materials readily available and the manufacturing costs controllable. Overall, this patented technology features a simple structure, ease of operation, and low manufacturing costs, making it suitable for widespread application in the gypsum production industry.

Patent protection helps companies build technological barriers.

According to the patent certificate information, the patent term for this utility model patent is ten years, commencing on December 30, 2021. The patentee is required to pay the annual fee before December 30th of each year in accordance with the Patent Law and its Implementing Regulations to maintain the validity of the patent right.

This patent authorization not only affirms the R&D capabilities of Guangxi Qinglong Chemical Building Materials Co., Ltd. and Guangdong Qinglong Construction Engineering Co., Ltd. in the field of gypsum production equipment, but also builds a strong technological barrier for the companies in market competition. With the continued growth in demand for gypsum products in the construction industry, this space-saving vertical molding frame technology is expected to play a positive role in improving production efficiency and reducing production costs.

Patented technologies help industries improve quality and efficiency.

Against the backdrop of increasingly scarce land resources and continuously rising production costs, achieving space conservation and capacity enhancement through technological innovation is a crucial direction for the transformation and upgrading of gypsum production enterprises. The vertical formwork technology, for which Guangxi Qinglong Chemical Building Materials Co., Ltd. and Guangdong Qinglong Construction Engineering Co., Ltd. recently obtained patent authorization, provides the industry with a practical and feasible solution.

In the future, with the further promotion and application of this technology, it is expected to help more gypsum production enterprises expand their production scale, improve production efficiency, and enhance economic benefits, thus promoting the gypsum production industry towards a more intensive and efficient direction.
