Problems solved by technology

Since the density and strength of the grout in the sleeve or in the round hole cannot be tested non-destructively on site, this connection method has caused considerable controversy in the industry, and has even been questioned by structural engineers. The cost of the method is high, which increases the overall cost of prefabricated concrete components, which is not conducive to the promotion and popularization of prefabricated buildings; and the bolt connection in the mechanical connection is also difficult to popularize because of the high cost; and other methods in the mechanical connection , and welded connections, lashing connections, etc. are mainly used for cast-in-place parts of concrete components

Abstract

The invention relates to a ring rib pin tenon connection structure of concrete members with pin bolt connection used in combination with tenon connection. The ring rib pin tenon connection structure of the concrete members is characterized in that the ring rib pin tenon connection structure consists of pre-embedded ring ribs, reserved tenon grooves, reserved pin holes, pins and grouting slurry ofthe concrete members; connection ends of two concrete members connected to each other are provided, wherein one ends are the pre-embedded ring ribs, and the others are the reserved tenon grooves and pin holes; the pre-embedded ring ribs of one member or tenons pre-embedded with ring ribs are inserted into the tenon grooves of another member; the pins are then inserted into the reserved pin holes;bonding slurry is filled or injected into the gaps inside the tenon grooves and pin holes of the members; after the slurry solidifies, the slurry becomes grouting slurry, and the two concrete membersare connected together. A construction method of the ring rib pin tenon connection structure is also related to. The ring rib pin tenon connection structure and the construction method thereof have the advantages of not only reducing costs but also improving safety of the structure, facilitating construction and inspection, and having broad application prospects.

Description

technical field [0001] The invention relates to the technical field of concrete structures in civil engineering, in particular to a connection structure of concrete components, in particular to a ring reinforcement pin tenon connection structure of concrete components and a construction method thereof. Background technique [0002] At present, the gradual replacement of cast-in-place concrete structures by prefabricated concrete structures is an inevitable trend in the development of the construction industry, and has even become a national development strategy. The connection technology of prefabricated concrete components in the construction of prefabricated concrete structures is usually in the form of sleeve grouting connection, grout anchor lap connection, mechanical connection, welding connection and lashing lap connection. Among them, the first two are the main connection forms of vertical prefabricated components. The connection principles of the two are similar. The...
