Bond type connector and bond type steel pipe bundle assembly

Abstract

The invention relates to a bond type connector and a bond type steel pipe bundle assembly, and belongs to the field of steel structures. The invention provides two technical schemes: (1) the bond typeconnector comprises a bag, a middle piece, a first connected piece and a second connected piece; the bag comprises a sealed peripheral side wall and a bottom plate, and is a container with a middle cavity opened toward the top surface; the first connected piece is connected with the bag; the middle piece is connected with the second connected piece; and the middle piece stretches into the cavityfrom the opening and is adhered tightly by a filled binder; and (2) the bond type steel pipe bundle assembly comprises an upper steel pipe bundle and a lower steel bundle; more than one steel unit isarranged and connected sequentially so as to enclose to form steel pipes with cavities; the upper steel pipe bundle and the lower steel pipe bundle comprise first flanges, second flanges and web; thewebs are separation plates of the adjacent steel pipes; and the webs of the upper steel pipe bundle and the lower steel pipe bundle are connected by adopting the bond type connector. The bond type connector and the bond type steel pipe bundle assembly provided by the invention are beneficial to saving steel materials, simple in structure, convenient to manufacture, and suitable for connecting thesteel pipe bundles at any position.

Description

technical field [0001] The invention belongs to the field of steel structures in the construction industry, and in particular relates to a steel pipe bundle connection. Background technique [0002] At present, concrete is poured into the steel pipe bundles as shear walls or columns. The steel pipe bundles are prefabricated in the factory, and the upper and lower steel pipe bundles are connected on the construction site. Since the separating webs of adjacent steel pipes are enclosed inside, the site cannot be directly connected by welding or bolts. , usually using the lap connection of inserting steel bars of equal area, it takes about 90d (d is the diameter of the steel bar) to lap the webs of the upper and lower steel tube bundles, which is very wasteful, and the steel bars are thick and dense, which affects the quality of concrete pouring; because concrete The tensile and shear strength of the joint is only about 2Mpa, which cannot reliably transmit the force of the upper...
