Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and in particular relates to an assembled earthquake-resistant steel frame for steel structure buildings. Background Art

[0002] Steel structure engineering is a structure made mainly of steel. It is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. It is one of the main types of building structures.

[0003] Since conventional steel structures lack earthquake-resistant mechanisms, when an earthquake occurs, the vibration acts directly on the top, and the vibration intensity attenuation is relatively small, which has a relatively large destructive force on the top steel structure, resulting in the problem of relatively low earthquake resistance of conventional steel structures.

[0004] To this end, we proposed an assembled earthquake-resistant steel frame for steel structure buildings to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem of relatively low earthquake resistance of conventional steel structures and proposes an assembled earthquake-resistant steel frame for steel structure buildings.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The assembled earthquake-resistant steel skeleton for steel structure buildings includes a pillar, a buffer spring is inserted into the upper part of the pillar, a nut is threadedly installed on the lower part of the buffer spring, the upper end of the buffer spring is fixedly connected to a mounting plate, a first conical spring is arranged between the pillar and the mounting plate, the upper end of the first conical spring contacts the lower end of the mounting plate, and the lower end of the mounting plate is fixedly connected to the pillar. During installation, the lower part of the buffer spring is inserted into the pillar so that the upper end of the first conical spring is supported on the lower end of the mounting plate, and the nut is screwed under the buffer spring so that the buffer spring is butted against the pillar. The crossbeam is installed on the mounting plate. When an earthquake occurs, the vibration is buffered by the first conical spring and the buffer spring and then acts on the mounting plate. The buffered force acts on the crossbeam through the mounting plate, thereby reducing the destructive strength of the vibration on the crossbeam and improving the earthquake resistance.

[0008] Preferably, the upper end of the mounting plate is hollowed out to form a mounting hole.

[0009] Preferably, a safety wire is embedded inside the nut, and the safety wire passes through the lower part of the buffer spring. After the nut is screwed onto the lower part of the buffer spring, the safety wire is embedded into the lower part of the nut, and the safety wire passes through the buffer spring to prevent the nut from loosening.

[0010] Preferably, the pillar comprises a column and a socket, and the socket is symmetrically fixedly connected to the upper part of the column. The socket facilitates the docking of the buffer spring and the pillar.

[0011] Preferably, the pillar further comprises a reinforcing plate, which is fixedly connected between the column and the socket, and the reinforcing plate is used to increase the firmness between the column and the socket.

[0012] Preferably, the buffer spring includes a second conical spring and a threaded column, and the lower end of the second conical spring is fixedly connected to the threaded column. The vibration of the socket acts on the second conical spring through the threaded column, and then acts on the mounting plate after being buffered by the second conical spring, so as to reduce the vibration intensity of the mounting plate.

[0013] Preferably, the nut comprises a hexagonal spiral ring, and a limited rotation groove is provided at the lower end of the hexagonal spiral ring. The iron wire is passed through the limited rotation groove and then through the threaded column, and the iron wire is bent to prevent the nut from rotating in a loose direction.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Install the crossbeam on the mounting plate. When an earthquake occurs, the vibration is buffered by the first conical spring and the buffer spring and then acts on the mounting plate. The buffered force is applied to the crossbeam through the mounting plate, thereby reducing the destructive force of the vibration on the crossbeam and improving the earthquake resistance.

[0016] 2. After screwing the nut onto the lower part of the buffer spring, embed the safety wire into the lower part of the nut and pass the safety wire through the buffer spring to prevent the nut from loosening.

[0017] 3. The vibration of the socket acts on the second conical spring through the threaded column, and then acts on the mounting plate after being buffered by the second conical spring, so as to reduce the vibration intensity of the mounting plate. BRIEF DESCRIPTION OF THE DRAWINGS
