Description

Technical Field

[0001] The utility model belongs to the technical field of assembled building structures, and in particular relates to an assembled connection device for a steel pipe column. Background Art

[0002] With the construction of green prefabricated buildings, steel pipe columns are widely used in large-span steel structure buildings, column components of high-rise and super-high-rise steel structure buildings, and bridge structures.

[0003] At present, the auxiliary connection device used for the segmented connection of steel pipe columns is usually to temporarily weld the ear plates to the upper and lower steel pipe columns, and then use the clamping plate to connect with the ear plates through bolts. Specifically, four ear plates are generally temporarily welded around the upper and lower steel pipe columns. Before hoisting, the slag and floating rust on the top surface of the lower steel pipe column and the bottom surface of the upper steel column should be cleaned to ensure that the upper and lower steel columns are in contact and tight. After the steel pipe column is hoisted into place, the center line of the steel pipe column should coincide with the center line of the lower section of the steel pipe column, and all four sides are taken into consideration. The clamping plate is respectively connected and fixed with the ear plates on the upper and lower steel pipe columns by bolts. After the temporary clamping plate is connected, the steel pipe columns are welded. After the steel pipe column is welded, the ear plates are cut off and polished flat, which causes damage to the ear plates. The welding and cutting process is easy to cause damage to the steel pipe column. Its installation and disassembly takes a lot of time, increases the construction cost, reduces the construction efficiency, and does not utilize turnover and recycling. Utility Model Content

[0029] See also Figures 1 to 4 As shown, the embodiment of the utility model provides a steel pipe column assembly connection device. The steel pipe column assembly connection device includes a plurality of connection components 1 and two limit components 2 for fixing on the steel pipe column 8, and a gap 4 is formed between the two limit components 2. After the two limit components 2 are respectively fixed on the two mutually butted steel pipe columns 8, the gap 4 is used for construction workers to weld and fix the weld between the two mutually butted steel pipe columns 8.

[0030] In the above embodiment, the limiting assembly 2 includes a fastener 21 and two half-rings 22 for sleeved steel pipe columns 8. The two half-rings 22 are detachably connected by the fastener 21. The two half-rings 22 surround a through hole 3 for penetrating the steel pipe column 8. The two half-rings 22 are sleeved on the steel pipe column 8, and the ends of the two half-rings 22 are butted against each other, and then the fastener 21 is used to lock the two half-rings 22 so that the two half-rings 22 are connected and sleeved on the side wall of the steel pipe column 8. In this way, before the two steel pipe columns 8 are butt-welded, one of the limiting assemblies 2 is fixed to the end of one of the steel pipe columns 8, and the other limiting assembly 2 is fixed to the end of the other steel pipe column 8. The half-ring 22 on one limiting assembly 2 and the half-ring 22 on the other limiting assembly 2 are detachably connected by the connecting assembly 1 through the gap 4, so that the two butt-jointed steel pipe columns 8 can be temporarily fixed.

[0031] In the above embodiment, the semi-ring member 22 includes a semi-ring portion 221, a first half ear portion 222 and a second half ear portion 223. The first half ear portion 222 and the second half ear portion 223 are respectively connected to the upper and lower ends of the semi-ring portion 221, and the first half ear portion 222 and the second half ear portion 223 are both protruding from the outer side wall of the semi-ring portion 221, and are connected to the second half ear portion 223 through a connecting assembly 1.

[0037] In the above embodiment, the semi-ring portion 221 , the connecting plate 7 , the first stiffening plate 5 and the second stiffening plate 6 are integrally formed, so as to further improve the overall strength of the semi-ring member 22 .

[0038] In the above embodiment, the fastener 21 includes a first screw 211 and a first nut 212 . The first screw 211 passes through the connecting plate 7 and is fastened to the first nut 212 , so that the two half-rings 22 are detachably connected through the fastener 21 .

[0039] In the above embodiment, the connecting assembly 1 includes a second screw 11, a second nut 12 and a pad 13. The second screw 11 passes through the two opposite second half-ears 223 and passes through the pad 13 to be fixedly connected with the second nut 12, so that the pad 13 rests on the second half-ear 223, so that the two limit assemblies 2 can be detachably connected through the connecting assembly 1.
