Description

Detachable and replaceable precast beam column Technical Field The utility model relates to the technical field of detachable and replaceable precast beam columns, in particular to a detachable and replaceable precast beam column. Background The fabricated reinforced concrete building is a core form of building industrialization, and has the remarkable advantages of high construction speed, short construction period, quality improvement, energy conservation, consumption reduction, clean production and the like. Building industrialization and engineering structural earthquake resistance face higher requirements and challenges, which require that the main load bearing members be quickly repaired after damage and that the load bearing capacity be maintained at a considerable level. The traditional connection mode of assembled column and foundation, such as plug-in connection, tenon connection and thick liquid anchor connection, has the problems of complex procedure structure, inconvenient construction, great difficulty, high manufacturing cost, difficult quality control, indirect load transmission, incapability of being replaced after damage, and the like. Disclosure of utility model The utility model aims to provide a detachable and replaceable precast beam column so as to solve the problem that the precast beam column cannot be replaced after the traditional assembly type column is damaged in a connecting mode. In order to achieve the purpose, the detachable and replaceable precast beam column comprises an upright post arranged at the upper end of a foundation, openings are formed in four corners of one end, close to the foundation, of the upright post, first connecting pieces are arranged at the openings, each first connecting piece comprises a first connector, an anchor bolt and first reinforcing steel bars, the first connectors are arranged at the openings, the first connectors can seal the openings, the anchor bolts are arranged in the foundation, first nuts are connected with one ends of the anchor bolts penetrating into the connectors in a threaded manner, the first reinforcing steel bars are arranged in the upright post, the first reinforcing steel bars are located above the first connectors, second nuts are connected with one ends of the first reinforcing steel bars penetrating into the first connectors in a threaded manner, and concrete is poured in the upright post. The method has the advantages that the first connectors are arranged in the upright posts, then the first reinforcing steel bars are arranged in the upright posts and connected with the first connectors, finally concrete is poured into the upright posts to form prefabricated upright posts, and the prefabricated upright posts can be detachably replaced through the detachable connection of the first connectors at the lower ends of the upright posts in the anchor bolts of the foundation, when the components are changed due to aging, damage or functional requirements, the components can be conveniently detached and replaced without large-scale detachment and reconstruction, the cost and difficulty of later maintenance and reconstruction are reduced, the first connectors are arranged at the openings at four corners of the upright posts, the upright posts are connected with the foundation deeply from a plurality of parts, the anchor bolts are matched with the first nuts to provide reliable anchoring force, and the upright posts are firmly fixed on the foundation; the first reinforcing steel bar penetrates into the first connector and is fixed by the second nut, the integrity and the stability of connection are further enhanced, the external force effect can be effectively resisted, the structural safety is guaranteed, the first connector can seal the opening, the construction mode is favorable for construction operation, all parts can be accurately positioned in the installation process, meanwhile, the internal connecting parts can be protected to a certain extent, the corrosion of external factors to the connecting parts is reduced, the service life of the structure is prolonged, the tightening degree of the nuts is guaranteed to meet the design requirement by tools such as torque spanners, and the reliability and consistency of connection are guaranteed.
