Product introduction: Gypsum board is an indispensable decorative material in decoration engineering. The traditional ordinary gypsum board often needs manual setting-out and positioning during construction, which has poor accuracy, an additional construction process, low work efficiency, long construction period and high product breakage rate. In the construction site, the position of elastic line is not fixed or accurate, and the phenomenon of blind drilling of construction screws often occurs, which not only destroys the integrity of gypsum board system, but also seriously reduces the sound insulation and fire prevention performance of gypsum board system. Even if the artificial elastic line positioning is carried out, there are practical problems such as irregular keel spacing and screw spacing (for example, the construction spacing of these two screws is 20cm, while the construction spacing of the other two screws may become 18cm), which leads to poor stress in the ceiling or partition wall system, leading to serious engineering quality problems such as cracking and deformation within a period of time after the gypsum board system is completed; There is no clear standard for the distance between the keel and the screw in the construction site, and the distance between the keel in the construction site is generally irregular, which makes the construction supervision difficult and the acceptance workload complicated. The nonstandard construction of ordinary gypsum board system due to the lack of clear standards for the distance between keel and screw in site construction is the main reason for serious engineering quality problems such as sound insulation, decreased fire resistance, cracking and deformation of gypsum board system.
Keyi Kangding gypsum board won two national patents, which realized the factory positioning and completely solved the technical problems of difficult positioning and construction of ordinary gypsum board system. Positioning line gypsum board system accurately sets the building installation positioning line on the gypsum board construction surface according to the national construction specification, with accurate positioning, which can be directly used in the construction site without manual positioning line, thus reducing the labor intensity of workers and the damage rate of gypsum board, with high efficiency, short construction period and simple and clear supervision and acceptance work; Not only does it put an end to the phenomenon of blind drilling of empty screws and crooked screws, but it also ensures that the excellent sound insulation and fire prevention performance of gypsum board system will not be reduced because of inadequate construction; The worldwide problem of uneven internal stress caused by uneven spacing between keel and screw and hidden trouble of engineering quality caused by irregular construction of gypsum board system is thoroughly solved, which ensures that the gypsum board system of positioning line will not crack and deform for a long time and realizes significant technical progress in the field of gypsum board system.
