Integral tubular anchor bolt pair adopting inorganic anchoring material
The invention discloses an integral tubular anchor bolt pair adopting an inorganic anchoring material, which comprises a tubular anchor bolt rod body which is inserted into an anchor hole of a concrete member and is provided with a full-length hollow through inner hole, and an expansion self-locking end which is arranged at the bottom end of the anchor bolt rod body and is used for temporarily fixing the anchor bolt rod body at the bottom of the anchor hole, the anchor locking flat head is arranged at the top end of the anchor bolt rod body and used for fixing an anchored part, a gap formed by the anchor bolt rod body and a concrete hole wall is communicated with a through inner hole of the anchor bolt rod body, and inorganic anchoring materials are poured into the anchor bolt rod body through pressure. The inorganic anchoring material is diffused from the anchor bolt rod body to concrete hole wall gaps under the action of pressure until the gaps are completely filled; the formed anchor bolt is simple in structure, reliable in anchoring and good in fire resistance, the service life of the anchor bolt can be the same as that of a main body structure, normal displacement of the steel plate relative to a concrete surface can be directly limited, relative shear displacement of the anchor bolt and the steel plate in the surface can be eliminated, and the direct shear stress relation between an anchored part and the anchor bolt is formed.
本发明公开一种采用无机锚固料的整体式管状锚栓副，包括用于插设于混凝土构件锚孔内的具有全长中空贯通内孔的管状锚栓杆体，和设置于锚栓杆体底端的用于将锚栓杆体临时固定于锚孔孔底的膨胀自锁端，以及设置于锚栓杆体顶端的用于固定被锚固件的锁锚平头，锚栓杆体与混凝土孔壁形成的间隙与锚栓杆体的贯通内孔连通设置，向锚栓杆体内压力灌注无机锚固料，无机锚固料在压力作用下从锚栓杆体内向混凝土孔壁间隙扩散填充直至完全填充间隙；所形成的锚栓构造简单、锚固可靠、抗火性能好并能与主体结构同寿命，既能直接限制钢板相对于混凝土面的法向位移，也能消除锚栓与钢板在面内的相对剪切位移，形成被锚固件与锚栓之间的直接剪切受力关系。
