Abstract

The invention relates to an improved assembled constructional reinforced concrete structural member which is characterized in that the connecting end of the concrete structural member extends to form a concrete structure or connecting reinforcement; and the head of the concrete structural member is a cylindrical bolt head and / or a cylindrical thread head which is thickened in the radial direction and has the peripheral thickness of more than or equal to 4mm; the inner side of a bolt head at the cylindrical bolt head end is preliminarily sleeved with a connecting sleeve, of which the outer end is an internal thread and the inner end is a neck. During structural member assembly and reinforcement connection, only the connecting sleeve is needed to be moved outwards along the axial direction and rotated to be screwed together with the cylindrical thread head connected to the other end of the connecting sleeve, so that sleeve connection can be used for locating the reinforcement connection of the assembled concrete structural member, stress strength is achieved after the connection is finished, the construction speed for assembling and connecting the concrete structural member is greatly increased, the strength of a joint is greater than that of reinforcement base metal, the joint is stable in reliability and is not influenced by personal factors, only one connecting sleeve is needed, and therefore, smaller length of only 60-100mm is needed, materials are saved, the connection cost is low, and the defects of large construction workload for assembling an assembled reinforced concrete building in situ, labor waste for in-situ assembly construction, low speed and instable quality are overcome.

Description

technical field

[0001] The present invention is an improvement to reinforced concrete components of prefabricated buildings, and in particular relates to a prefabricated building which is suitable for on-site positioning and assembly of components, does not need to be welded for connection of steel bars of structural parts, quick on-site assembly, reliable connection and good stability, and low cost of steel bar connection Reinforced concrete components. Background technique

[0002] Reinforced concrete prefabricated buildings, because the concrete components are prefabricated in the factory and transported to the construction site for assembly and assembly, it has the advantages of saving building materials, less on-site construction, quick construction, good quality assurance and construction environmental protection, and can realize the industrialization of the factory. gradually gained attention and promotion. However, the assembly and connection of building structural ...
