The invention discloses a prestress clasp nail structure for masonry reinforcement. The prestress clasp nail structure comprises a forward rotation wall nail and a reverse rotation wall nail, each ofthe forward rotation wall nail and the reverse rotation wall nail is in a right angle shape formed by a first section and a second section, and a forward rotation external thread and a reverse rotation external thread are respectively arranged at the free ends of the first sections of the forward rotation wall nail and the reverse rotation wall nail, a forward rotation internal thread matched withthe forward rotation external thread and a reverse rotation internal thread matched with the reverse rotation external thread are arranged at the two ends of a hole of a fastening sleeve respectively, nuts are in threaded connection with the middles of the second sections of the forward rotation wall nail and the reverse rotation wall nail respectively, the diameters of the free ends of the second sections of the forward rotation wall nail and the reverse rotation wall nail are gradually increased to form conical heads, a gasket and an expansion sleeve respectively sleeve the forward rotationwall nail and the reverse rotation wall nail between the nut and the conical heads, strip-shaped grooves are formed in the ends, facing the conical heads, of the expansion sleeves in the length direction and extend to the free ends of the expansion sleeves, the inner diameter of the expansion sleeves is consistent with the outer diameter of the middle section of the conical heads, the forward rotation wall nail section and the reverse rotation wall nail section which are provided with the expansion sleeves are located in drilled holes in the adjacent masonry respectively, and fastening sleeves are located on the surface of a wall body. The structure can reliably reinforce the masonry.
本发明公开了一种砌体加固用预应力扒钉结构，包括正旋墙钉和反旋墙钉，它们均由一段和二段构成直角形，正旋墙钉和反旋墙钉的一段自由端分别设有正旋外螺纹和反旋外螺纹，一紧固套筒的孔两端分别设有与正旋外螺纹适配的正旋内螺纹和与反旋外螺纹适配的反旋内螺纹，正旋墙钉和反旋墙钉的二段中部分别螺纹连接有螺母，正旋墙钉和反旋墙钉的二段自由端直径逐渐变大呈锥头，螺母与锥头之间的正旋墙钉和反旋墙钉上分别套设有垫片和膨胀套筒，朝向锥头的膨胀套筒端沿其长度方向设有条形槽，条形槽延伸到膨胀套筒自由端，膨胀套筒内径与锥头中段外径一致，带膨胀套筒的正旋墙钉段和反旋墙钉段分别位于相邻砌体上所钻孔内，紧固套筒位于墙体表面上；该结构能可靠加固砌体。
