TECHNICAL FIELD

[0001] The utility model relates to steel structure technical field, specifically is a steel structure installation base. BACKGROUND

[0002] Steel structure base is an important component in steel structure engineering, which is directly related to the stability and safety of the whole structure. The commonly used materials of steel structure base include concrete, high-strength steel and the like. The concrete base has good bearing capacity and durability, and the steel structure base is often used in high-rise buildings due to its high strength and toughness.

[0003] In the prior art, when connecting the base and the I-beam, the lower end of the I-beam is usually fixed and installed on the concrete base by using a bolt fastener, achieving relatively firm and close installation. However, this connection form makes all the components be hard connected, so that the I-beam rigidly conducts the force to the remaining components when stressed, lacking a buffer space, so that the overall structure has poor seismic resistance. UTILITY MODEL CONTENT

[0004] The utility model solves the above-mentioned technical problem that the I-beam rigidly conducts the force to the remaining components when stressed, lacking a buffer space, so that the overall structure has poor seismic resistance, and provides a steel structure installation base.

[0005] To solve the above technical problem, the utility model provides a technical scheme of a steel structure installation base, which comprises an I-beam and further comprises:

[0006] a mounting frame, which is welded to the lower end of the I-beam, is hollow inside and is provided with four openings at four corners, has an open upper end, and is provided with a cover plate on the upper surface;

[0007] a damping member, which is hot-bent and formed from metal material and has a U-shaped longitudinal section; the damping member is detachably connected to the mounting frame and the cover plate at opposite ends;

[0008] a base, which is located below the damping member and is welded to the end of the damping member.

[0009] Further, the longitudinal section of each opening is dovetail-shaped.

[0010] Further, a metal pin is arranged at the lower end in each opening, and a limiting strip is rotatably arranged at the upper end of the metal pin; a through groove one is arranged at the upper end of the damping member and can accommodate the limiting strip, and a through groove two corresponding to the through groove one is arranged on the cover plate.

[0011] Further, the length of the limiting strip is smaller than the length of the through groove one and the through groove two and greater than the width of the through groove one and the through groove two.

[0012] Further, the base is integrally poured into concrete when installed.

[0013] Further, the base is provided with a plurality of reinforcing legs, the reinforcing legs are L-shaped, and the lower ends thereof are directed in different directions.

[0014] Compared with the prior art, the utility model has the advantages of:

[0015] By adopting the heat-pressed metal damping member with a certain thickness, the rigid connection between the I-beam and the base is reduced, thereby reducing vibration conduction and improving the overall seismic resistance.

[0016] The damping member and the mounting frame at the upper end are not completely fixedly connected, and there is a deformation displacement space, so that buffering is further realized and vibration conduction is reduced when actually stressed. BRIEF DESCRIPTION OF DRAWINGS
