The invention discloses an assembled concrete building connection structure, which belongs to the technical field of building structures. The connecting structure includes a first prefabricated component and a second prefabricated component, the end of the first prefabricated component is pre-embedded with a connecting
pipe, the second prefabricated component is pre-embedded with a plug-in component that matches the connecting tube, the plug-in component is connected to the The
pipe fittings are plugged in, and the plug-in components and the connecting pipes are also fixed as a whole through pouring concrete. The embedded section of the plug-in components includes a tubular shell, a
limiter and a
perfusion channel. The tubular shell and the
perfusion channel are connected by a
limiter, and the
limiter The fittings are fixed on the inner wall of the tubular shell, the plug-in section is inserted into the connecting
pipe fitting, and the embedded section is provided with a concrete pouring port. The connection structure of the present invention is simple in structure and reasonable in design, which improves the overall stability and
earthquake resistance of the concrete building; and has low
assembly difficulty, without multiple processes such as bolts and
welding, which significantly shortens the construction period and reduces construction costs.
