Detailed Description
The present invention will be described in detail with reference to specific embodiments.
The invention relates to a T-shaped steel plate socket fixed assembly type prefabricated external wallboard splicing piece which comprises a T-shaped steel plate 2, wherein two ends of the T-shaped steel plate 2 are inserted into the end surfaces of two adjacent concrete inner leaf plates 1 to realize splicing.
The T-shaped steel plate 2 comprises a flange plate 6 and a web plate 7, wherein the web plate 7 and the flange plate 6 are perpendicular to each other, and the cross section of the web plate forms a T shape. The flange plate 6 level of T style of calligraphy steel sheet 2 sets up, and the vertical setting of web 7, the terminal surface of lamina 1 in the horizontal both ends insert the concrete. Be provided with steel sheet bolt hole 5 on the web 7 of T style of calligraphy steel sheet 2, the position that lamina 1 corresponds steel sheet bolt hole 5 in the concrete is equipped with reserved bolt hole 4, utilizes bolt 3 to insert reserved bolt hole 4 and steel sheet bolt hole 5 and fixes T style of calligraphy steel sheet 2 and lamina 1 in the concrete mutually, realizes assembling of lamina 1 in two adjacent concrete. A plurality of steel plate bolt holes 5 are formed in one web plate 7 of the T-shaped steel plate 2. One side of the concrete inner blade plate 1 is provided with a reserved bolt hole 4, and a bolt 3 is sequentially inserted into the reserved bolt hole 4 and a steel plate bolt hole 5 of a T-shaped steel plate 2 web plate 7 from the side.
