Problems solved by technology

The volume of the steel columns of high-rise steel structures increases with the extension of the longitudinal height and the change of the structural form. If the current traditional rigid support, cable wind rope and other temporary steel column fixing measures are used to install the steel components, the construction period will be greatly reduced. It cannot be guaranteed, and the staggered safe and civilized construction of each construction team cannot meet the requirements, which brings great difficulties to the installation accuracy
[0003] At present, the temporary installation of steel columns in super high-rise steel structures adopts temporary steel supports and cable wind ropes to support and stabilize them, which requires a large investment of construction measures and labor, which increases the construction content and working hours, and requires multiple types of work and multiple processes. The three-dimensional intersection operations affect each other, which brings hidden dangers to construction safety

Embodiment 1

[0022] This embodiment provides a connecting device for butt jointing of steel columns, which is used for butt jointing of an upper steel column (which can be a vertical or inclined upper steel column) on a fixed lower steel column in the construction of a steel structure building, so that the upper steel column The steel column is temporarily fixed on the lower steel column, such as Figure 2~4 As shown, the connecting device includes: lug plate, connecting splint and bolt;

[0023] Among them, there are two ear plates, and the ear plates can be rectangular steel plates. The thickness of the ear plates is generally 20-30mm. Both ear plates are provided with bolt holes, and there are multiple bolt holes, which are evenly distributed on the ear plates. ;

[0024] There are also two connecting splints, and the connecting splints can also be rectangular steel plates. The thickness of the connecting splints is generally 12-18mm. Bolt holes are also provided on the two connecting ...

Embodiment 2

[0031] This embodiment provides a steel column butt joint installation method, which is used for butt installation of an inclined upper steel column on a fixed lower steel column, such as Figure 5 As shown, the steps of the method are as follows, specifically including:

[0032] The butt joints of the upper and lower steel columns to be connected are fixedly connected by the connection device provided in the first embodiment above;

[0033] Step S1, welding the lug plates of the connecting device to the butt ends of the butted upper and lower steel columns respectively;

[0034] Step S2, hoisting the upper steel column above the fixed lower steel column, adjusting the upper steel column to the installation position, so that the position of the ear plate welded at the butt end of the upper steel column corresponds to the position of the ear plate welded at the butt end of the lower steel column;

[0035] Step S3, clamping the lug plates welded at the butt ends of the upper an...

Abstract

The invention discloses a connecting device of a steel column butt joint and an installing method, belonging to the field of steel structure construction. The connecting device comprises two lug plates, two connecting clamp plates and bolts, wherein bolt holes are arranged on the two lug plates; the two connecting clamp plates are provided with bolt holes corresponding to the bolt holes on the two lug plates; and the two lug plates are arranged between the two connecting clamp plates and are fixedly connected into an integral structure through the bolts and the connecting clamp plates. The invention also provides an installing method of an incline steel column butt joint. The connecting device can be used in the butt joint of incline steel columns and is fixed on the butt joint of an upper steel column and a lower steel column to ensure that the upwards-inclining upper steel column is temporally fixed on the lower steel column through the connecting device without arranging a rigid support and pulling a cable wind rope and other temporary fixed facilities, thereby reducing the temporary fixed facilities used in the butt joint of incline steel column members, improving the installation progress of the construction of the steel structure, and shortening the construction period.

Description

technical field [0001] The invention relates to the field of steel structure construction, in particular to a connection device and an installation method for butt jointing of steel columns (steel tube columns and box-shaped columns) in steel structure construction. Background technique [0002] At present, the vertical development of high-rise buildings is getting higher and higher, and the structural design is becoming more and more novel and peculiar, which brings great challenges to the installation technology of super high-rise steel structures. The volume of the steel columns of high-rise steel structures increases with the extension of the longitudinal height and the change of the structural form. If the current traditional rigid support, cable wind rope and other temporary steel column fixing measures are used to install the steel components, the construction period will be greatly reduced. There is no guarantee, and the staggered safe and civilized construction of e...
