Splicing structure and splicing method of glass fiber reinforced cement prefabricated part
The invention discloses a splicing structure and a splicing method of glass fiber reinforced cement prefabricated parts, the splicing structure comprises a plurality of mutually spliced prefabricated plate bodies, a splicing seam is arranged between two adjacent prefabricated plate bodies, a plurality of horizontal reinforcing bars are arranged on the left and right side surfaces of the prefabricated plate bodies, and the horizontal reinforcing bars are arranged on the left and right side surfaces of the prefabricated plate bodies. The horizontal reinforcing bars on one sides of every two adjacent prefabricated slab bodies are arranged in a splicing seam, the horizontal reinforcing bars and the splicing seam are bound and fixed through steel wires, a seam filling material is poured into the splicing seam, an alkali-resistant fiber cloth layer is laid on the position, close to the upper surface of the splicing seam, of the seam filling material, and epoxy resin mixed glue is smeared on the surface from the alkali-resistant fiber cloth layer to the splicing seam. According to the invention, the horizontal reinforcing bars are reserved on the prefabricated slab body, so that the shrinkage cracking of the joint filling material in the gaps can be effectively reduced, and the alkali-resistant fiber cloth layer can play a surface layer anti-cracking role, thereby effectively solving the problem that the splicing seam parts between the large-scale GRC modeling single pieces are easy to crack.
本发明公开了一种玻璃纤维增强水泥预制构件的拼接结构及拼接方法，其拼接结构包括：多个相互拼接的预制板本体，相邻两个预制板本体之间设有拼接缝，其中，预制板本体的左右侧面上均设于多个胡子筋，相邻两个预制板本体一侧的胡子筋均置于拼接缝内，且二者通过钢丝捆绑固定，拼接缝内灌注有填缝材料，填缝材料上靠近拼接缝的上表面的位置铺贴耐碱纤维布层，耐碱纤维布层至拼接缝的表面涂抹有环氧树脂掺胶。本发明通过在预制板本体上预留胡子筋，可以有效减少缝隙中的填缝材料的收缩开裂，并且耐碱纤维布层可以起表层抗裂作用，从而有效解决了大型GRC造型单件之间拼接缝部位易开裂的问题。
