Description
Technical field
The utility model relates to a kind of building prefabricated components, is specifically related to a kind of novel prefabricated post, belongs to technical field of civil engineering.
Background technology
In order to enhance productivity, reduce personnel labor intensity, and improve the building unit quality, at present in the industrialization of construction industry field, generally studying the prefabricated of reinforced concrete building member, as reinforced concrete prefabricated column, reinforced concrete prefabricated beam, reinforced concrete prefabricated board.
Wherein, aspect reinforced concrete prefabricated column, the key technology difficult point that need to solve is the hypomere prefabricated post and being connected of epimere prefabricated post, two kinds of solutions are arranged at present, the one, hypomere prefabricated post vertical reinforcement is reserved long length at the prefabricated post end face, and stretch out floor end face certain-length, and the epimere prefabricated post is connected with steel bar connector at the lower end vertical reinforcement, the floor between the last hypomere prefabricated post build finish after, the epimere prefabricated post risen winch to the relevant position, and the vertical reinforcement that the reinforcing bar prefabricate that makes epimere prefabricated post lower end stretches out flooring with the hypomere prefabricated post is inserted in, and one by one steel bar connector injected high-strength fast hard non-shrinkage cement mortar then.Another kind of way is that last hypomere prefabricated post is connected vertical reinforcement in corresponding bean column node position by welding or mechanical connection manner, adopt diagonal brace then or utilize up and down the built-in connection of shell of column make the epimere prefabricated post at beam-column connection and corresponding floor plates construction stage retaining member the plane stability under wind load and other horizontal loads.
The first method key of success is the quality of reinforcing bar connector and high-strength fast hard non-shrinkage cement mortar, its corresponding technical requirements is higher, the problem that exists is that each root vertical reinforcement all needs a reinforcing bar connector, and need slip casting one by one, cost of production is higher, and it is more loaded down with trivial details to construct, and the centering requirement of last hypomere prefabricated post vertical reinforcement and reinforcing bar connector is high, the centering difficulty is big, particularly when last prefabricated post reduced cross-sectional, all the more so.Therefore the prefabricated post of using this method to connect generally is applicable to multilayer, up and down the unconverted building of column section.
The difficult point of second method construction is at the intensive position of this reinforcing bar of beam-column connection, because there being the built-in connection of prefabricated post, can make that the beam longitudinal reinforcement that stretches into bean column node passes through bean column node for the built-in connection of avoiding prefabricated post need detour, so increased the beam steel difficulty of processing, also influenced the anchoring effect of beam steel, on the other hand in order to guarantee that the epimere prefabricated post is keeping plane stability at beam-column connection and corresponding floor plates construction stage, its built-in connection cross section can be bigger, and the connection of prefabricated post built-in connection and vertical reinforcement are to be in a kind of work high above the ground state when connecting, both dangerous also inconvenient, efficiency of construction is lower.Therefore this connected mode is applicable to the building that column section is less, the floor floor height is lower.
