Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
In the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or positional relationship shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the apparatus or element of the present invention must have a specific orientation, and thus, should not be construed as limiting the present invention.
Examples
As shown in fig. 1 to 3, a steel structure closed member connection structure includes an inner sleeve steel pipe 100, and an upper column steel pipe 200 and a lower column steel pipe 300 sleeved outside the inner sleeve steel pipe 100, wherein the inner sleeve steel pipe 100, the upper column steel pipe 200 and the lower column steel pipe 300 are connected by bolts, corresponding bolt holes 400 are formed at the joints, and corresponding nuts 110 are fixedly disposed inside the bolt holes 400 of the inner sleeve steel pipe 100.
The nuts 110 are fixed inside the bolt holes 400 of the inner sleeve steel pipe 100 by welding. The bolt hole 400 has a diameter equal to the inner diameter of the nut 110.
The inner walls of the upper column steel pipe 200 and the lower column steel pipe 300 are attached to the outer wall of the inner sleeve steel pipe 100. The cross-sectional shapes of the upper column steel pipe 200 and the lower column steel pipe 300 are the same as the cross-sectional shape of the inner sleeve steel pipe 100. The cross section of the inner sleeve steel pipe 100 is rectangular.
The inner wall of the bolt hole 400 is provided with threads, so that the tightness of bolt connection is improved, and the stability of the connection node is improved.
When the steel pipe is installed, the bolt 500 only needs to be screwed in from the outside, and the nut 110 is already fixed on the inner side of the bolt hole 400 of the inner sleeve steel pipe 100, so the operation space is large when the steel pipe is installed, and the steel pipe is not limited by the narrow space in the steel pipe; in addition, the inner sleeve steel tube 100, the upper column steel tube 200 and the lower column steel tube 300 are connected through bolts, so that the mounting and dismounting efficiency is improved, and the recovery is facilitated.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
