Problems solved by technology

The connection of box-section steel pipe members is generally welded, but welding at the construction site is slow in efficiency and unstable in quality
With bolt connection, the closed box shape of the component cross-section affects the bolt tightening operation. It is often necessary to "open the skylight" on the side wall and then weld it closed. The construction is inconvenient and difficult to disassemble. The above two methods are especially not suitable for small cross-section box shapes. Cross-section steel pipe members and unit houses where most of the interior and exterior decoration is completed in the factory and need to be disassembled flexibly

Embodiment

[0023] Such as figure 1 , 3 As shown, a connection device for a box-section steel pipe member includes an upper box-section steel pipe member 10, a lower box-section steel pipe member 20, an upper box-section steel pipe member 10 and a lower box-section steel pipe member 20 The connecting inner core 30 is placed inside the connecting inner core 30, and the width of the connecting inner core 30 is slightly smaller than the inner diameter of the box-section steel pipe member. The upper box-section steel pipe member 10 and the lower box-section steel pipe member 20 are respectively fixed to the connecting inner core 30 by bolts. The upper and lower ends of the connecting inner core 30 are respectively provided with threaded screw holes 33, and the upper box-shaped steel pipe member 10 and the lower box-shaped steel pipe member 20 are also provided with screw holes corresponding to the positions of the screw holes connecting the inner core 30. holes, can be fixed by long bolts. ...

Abstract

The invention discloses a connecting device for box-shaped section steel tube components. The connecting device comprises an upper box-shaped section steel tube component section and a lower box-shaped section steel tube component section. The upper box-shaped section steel tube component section and the lower box-shaped section steel tube component section are connected through connecting inner cores arranged in the upper box-shaped section steel tube component section and the lower box-shaped section steel tube component section. The upper box-shaped section steel tube component section and the lower box-shaped section steel tube component section are fixed to the connecting inner cores through bolts. Welding can be avoided during field splicing of the box-shaped section steel tube components with small sections, the bolt connecting operation is simple and convenient, and the connecting requirements of anti-knock steel structure frame beams and columns can be met.

Description

technical field [0001] The invention relates to the connection field of box-section steel pipe members, in particular to a connection device suitable for box-section steel pipe members with smaller cross-sections. Background technique [0002] Box-section steel pipe members are generally used in unit splices in unit houses for column connections. The connection of box-section steel pipe members is generally welded, but welding at the construction site is slow in efficiency and unstable in quality. With bolt connection, the closed box shape of the component cross-section affects the bolt tightening operation. It is often necessary to "open the skylight" on the side wall and then weld it closed. The construction is inconvenient and difficult to disassemble. The above two methods are especially not suitable for small cross-section box shapes. Sectional steel pipe members and unit houses where most of the interior and exterior decorations are done in the factory and need to be ...
