Heat-bridge-breaking anchor bolt suitable for fabricated type composite external wall panel

QUAN XIAONING

The invention discloses a heat-bridge-breaking anchor bolt suitable for a fabricated type composite external wall panel. The anchor bolt comprises a heat preservation box and a first diffusion plate, the left end of the first diffusion plate is fixedly connected with an internal thread pipe, the inner surface of the internal thread pipe is in threaded connection with a first lead screw, the left end of the first lead screw is fixedly connected with a second diffusion plate, a second screw rod is movably connected to the left side of the second diffuser plate, a first end is fixedly connected to the left side of the second diffusion plate, and a first through groove is formed in the surface of the first end. According to the heat-bridge-breaking anchor bolt suitable for the fabricated type composite external wall panel, by arranging the first diffusion plate and screwing the first lead screw into the internal thread pipe to be matched with the second diffusion plate and the first end, the shearing resistance of the heat-bridge-breaking anchor bolt is enhanced after the heat-bridge-breaking anchor bolt is installed, and a heat bridge can be broken; and meanwhile, a third through groove in the second lead screw can be fixed to a steel wire mesh of a steel wire mesh frame system, and the overall strength is improved.

本发明公开了一种适用于装配式复合外墙板的锚栓，包括保温箱和第一扩压盘，所述第一扩压盘的左端固定连接有内牙丝管，所述内牙丝管的内表面螺纹连接有第一丝杆，第一丝杆的左端固定连接有第二扩压盘，第二扩压盘的左侧活动连接有第二丝杆，第二扩压盘的左侧固定连接有第一端头，第一端头的表面开设有第一通槽，本发明涉及断热桥锚栓技术领域。该适用于装配式复合外墙板的断热桥锚栓，通过设置有第一扩压盘，将第一丝杆旋入内牙丝管中，配合第二扩压盘和第一端头等，使得断热桥锚栓在安装后不仅抗剪力加强，而且能实现断热桥，同时第二丝杆上的第三通槽可与钢丝网架体系的钢丝网进行固定，提高整体强度。
