Summary of the invention
The purpose of this utility model is to provide the beam-column connection of the employing steel tube concrete superposed column of a class easy construction.
The technical solution adopted in the utility model is:
Steel pipe and with the end board assembly of shaped steel welding on hole is set respectively, monolateral screw bolt passes end board assembly and steel pipe, be connected steel pipe with shaped steel; The outside of steel pipe and shaped steel is the vertical muscle of colligation post, column tie-bar, the vertical muscle of beam and beam stirrup respectively; The inner concrete of cast in steel pipe, steel pipe is poured into a mould outside concrete outward, and shaped steel is poured into a mould the beam concrete outward.
Described end board assembly is flush end plate or arc-shaped end plate.
The cross section of described steel pipe is square, rectangle or circle.
The transversal of described shaped steel is I shape or cross.
The beneficial effects of the utility model are:
(1) such connected node Path of Force Transfer is clear and definite, can effectively transmit or bear Shear force within the beam end and moment of flexure.Outside concrete can effectively be protected inner steel pipe, shaped steel and reinforcing bar under fire, delays the rising of steel temperature, improves the fire resistance of node.
(2) this category node does not need or only needs factory's welding job amount seldom, only need be on steel pipe and end board assembly the prepared screw-bolt hole hole, easy to process, the welding residual stress of having avoided Site Welding to cause and the impact of weldquality.
(3) adopt monolateral bolt on-the-spot splicing steel pipe and shaped steel, can erect fast overall frame construction, facilitate further reinforcing bar binding and concreting.
(4) its work progress has adopted factory's weldable steel parts, the assembled steel pipe of on-the-spot bolt and shaped steel to form the operation that steel frame, on-the-spot assembling reinforcement and concreting complete node construction, the reliable steel tube concrete superposed column connected node of can providing convenience, have advantages of that speed of application is fast, power transmission is clear and definite, fire resistance is good.
