天花石膏板背板加固结构
摘要：
本发明公开了一种天花石膏板背板加固结构，它包括主龙骨、轻钢龙骨副龙骨（8）、石膏板（1），石膏板（1）通过自攻螺丝（2）固定到轻钢龙骨副龙骨（8），石膏板（1）与石膏板（1）的接缝处预留有缝，缝内填充有嵌缝石膏（5）；小条石膏板（4）通过白乳胶（3）粘结在接缝处的背面，小条石膏板（4）位于相邻的轻钢龙骨副龙骨（8）之间，小条石膏板（4）对相邻的轻钢龙骨副龙骨（8）进行支撑；纸带（6）通过胶粘结在石膏板（1）与石膏板（1）的接缝处的正面，纸带（6）外部粘帖有白的确良布（7）。本发明能有效的规避因温度变化而导致的石膏板接缝开裂等问题；安装方便、省工省力，可模数化施工、产品化安装。
摘要（英）：

The invention discloses a ceiling gypsum board backboard reinforcing structure comprising a key keel, light steel keel rider keels (8) and gypsum boards (1). The gypsum boards (1) are fixed to the light steel keel rider keels (8) through self-tapping screws (2), and a seam is reserved in the joint of the gypsum boards (1) and filled with caulking gypsum (5). A small gypsum board (4) is adhered to the back of the joint through white latex (4) and located between the adjacent light steel keel rider keels (8) and supports the adjacent light steel keel rider keels (8). A paper tape (6) is adhered to the front of the joint of the gypsum boards (1) through glue, and white dacron cloth (7) is adhered to the outside of the paper tape (6). The problems of gypsum board joint cracking and the like caused by temperature variation can be avoided effectively; the ceiling gypsum board backboard reinforcing structure is convenient to install, laborsaving and capable of realizing modular construction and productized installation.
