Description

Technical Field

[0001] The utility model belongs to the technical field of earthquake-reducing and isolation structures, and in particular relates to a fireproof earthquake-reducing and isolation structure for building engineering. Background Art

[0002] Seismic isolation technology belongs to "flexible seismic resistance" and its seismic resistance effect is significantly better than traditional "rigid seismic resistance". It is currently the most advanced technology in the field of building seismic resistance. Building structure seismic reduction is equivalent to installing "fuses" on the main body of the building. Usually, these "fuses" are no different from ordinary structural components and they ensure the normal use function of the building in an elastic state. When an earthquake comes and the seismic force borne by these "fuses" exceeds their yield bearing capacity, the "fuses" will enter a state of "plastic deformation energy consumption" and "concentrate" and dissipate the seismic energy input into the building through reciprocating deformation.

[0003] The commonly used seismic isolation structure includes an outer shell, and a seismic isolation component installed inside the outer shell for energy absorption and shock reduction, usually a spring or a rubber plate. However, the elasticity of the above-mentioned seismic isolation component will be affected under high temperature conditions such as fire, which will greatly reduce the seismic isolation effect of the entire seismic isolation device and weaken the energy absorption and buffering effect during subsequent seismic isolation. Utility Model Content

[0004] The purpose of the utility model is to provide a fireproof construction engineering seismic isolation structure, which can protect the seismic isolation components and avoid the elasticity reduction caused by excessive temperature of the seismic isolation components in high temperature environments such as fire, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fireproof construction engineering seismic isolation structure, comprising a substrate and a seismic isolation component, wherein there are two substrates, the seismic isolation component is fixedly connected between the two substrates, a fireproof structure is fixedly connected between the two substrates, the seismic isolation component is arranged inside the fireproof structure, both ends of the seismic isolation component are fixedly connected with thermal insulation pads, and one end of the two thermal insulation pads is respectively fixedly connected to one side of the two substrates.

[0006] Furthermore, the side of the top end of the substrate is fixedly connected with mounting holes which are equidistantly distributed around the axis of the substrate.

[0007] Furthermore, the shock-absorbing and isolating component comprises a shell, the interior of which is fixedly connected with shock-absorbing rubber plates at equal intervals from top to bottom, and a lead core is embedded in the middle of the shell.

[0008] Furthermore, the fireproof structure includes a spring and a glass fiber fireproof tube, the two ends of the spring are respectively fixedly connected to one side of the two substrates, there are two glass fiber fireproof tubes, the two glass fiber fireproof tubes are respectively arranged on the inner side and the outer side of the spring, and the two ends of the glass fiber fireproof tube are respectively fixedly connected to one side of the two substrates.

[0009] Furthermore, the longitudinal section of the glass fiber fireproof tube is wavy.

[0010] Furthermore, a shaping cylinder is fixedly connected to one side of the glass fiber fireproof cylinder close to the spring. The shaping cylinder is made of rubber. Both ends of the shaping cylinder are fixedly connected to one side of the two base plates respectively.

[0011] Furthermore, the thermal insulation pad comprises a steel plate, the steel plate has several layers, and an asbestos layer is fixedly connected between every two upper and lower adjacent steel plates.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the fireproof structural cover is on the periphery of the entire seismic isolation component to protect the seismic isolation component, and in high temperature environments such as fires, it can prevent the seismic isolation component from overheating and causing a decrease in elasticity, thereby affecting the seismic isolation effect. The thermal insulation pad plays a role of insulation to prevent heat on the substrate from being transferred to the seismic isolation component, further reducing the impact of high temperature on the seismic isolation component.

[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] like Figure 1-3 As shown, a fireproof construction engineering seismic isolation structure includes a substrate 1 and a seismic isolation component 2, there are two substrates 1, the seismic isolation component 2 is fixedly connected between the two substrates 1, a fireproof structure 3 is fixedly connected between the two substrates 1, the seismic isolation component 2 is arranged inside the fireproof structure 3, both ends of the seismic isolation component 2 are fixedly connected with thermal insulation pads 4, one end of the two thermal insulation pads 4 is respectively fixedly connected to one side of the two substrates 1, the seismic isolation component 2 includes an outer shell 21, and shock-absorbing rubber plates 22 are fixedly connected to the inside of the outer shell 21 at equal distances from top to bottom, and a lead core 23 is embedded in the middle of the outer shell 21.

[0021] According to the above structure, when in use, the shock-absorbing rubber plate 22 plays a role of buffering and shock-isolating. The fireproof structure 3 covers the periphery of the shock-absorbing and isolation component 2 as a whole to protect the shock-absorbing and isolation component 2. In a high temperature environment such as a fire, the shock-absorbing and isolation component 2 can be prevented from overheating and causing a decrease in elasticity, thereby affecting the shock-absorbing and isolation effect. The thermal insulation pad 4 plays a role of heat insulation to prevent the heat on the substrate 1 from being transferred to the shock-absorbing and isolation component 2.

[0022] like Figure 1 As shown, the side of the top of the substrate 1 is fixedly connected with mounting holes 11 which are equidistantly distributed around the axis of the substrate 1 .

[0023] According to the above structure, when mounting, the base plate 1 is fixed at a target position by passing the bolts through the mounting holes 11 .

[0024] like Figure 3 and 4 As shown, the fireproof structure 3 includes a spring 31 and a glass fiber fireproof tube 32, the two ends of the spring 31 are fixedly connected to one side of the two substrates 1 respectively, there are two glass fiber fireproof tubes 32, the two glass fiber fireproof tubes 32 are respectively arranged on the inner side and the outer side of the spring 31, the two ends of the glass fiber fireproof tube 32 are respectively fixedly connected to one side of the two substrates 1, the longitudinal section of the glass fiber fireproof tube 32 is wavy, and the side of the glass fiber fireproof tube 32 close to the spring 31 is fixedly connected with a shaping tube 33, the material of the shaping tube 33 is rubber, and the two ends of the shaping tube 33 are respectively fixedly connected to one side of the two substrates 1.

[0025] According to the above structure, the glass fiber fireproof tube 32 has a heat insulating effect to prevent the high temperature in a fire environment from reducing the elasticity of the shock-absorbing rubber plate 22. The glass fiber fireproof tube 32 is wavy. When vibrated, the shock-absorbing and isolating component 2 will deform to buffer and absorb energy. The wavy shape of the glass fiber fireproof tube 32 can provide the necessary material length for the deformation of the glass fiber fireproof tube 32. The spring 31 plays a role in supporting the glass fiber fireproof tube 32. The shaping tube 33 can keep the glass fiber fireproof tube 32 wavy.

[0026] like Figure 4 As shown, the heat insulating pad 4 includes a steel plate 42, the steel plate 42 has several layers, and an asbestos layer 41 is fixedly connected between every two upper and lower adjacent steel plates 42.

[0027] According to the above structure, the asbestos layer 41 plays a role of heat insulation when in use. The asbestos layer 41 is arranged between adjacent steel plates 42, which can improve the overall heat insulation effect of the insulation pad 4 and prevent heat from being transferred to the shock-absorbing and isolating component 2 through the substrate 1.

[0028] The working principle of the utility model is as follows: during installation, the base plate 1 is fixed at the target position by passing bolts through the mounting holes 11. When in use, the shock-absorbing rubber plate 22 plays a role in buffering and isolating shocks. The fireproof structure 3 covers the periphery of the shock-absorbing and isolating component 2 as a whole to protect the shock-absorbing and isolating component 2. In a high-temperature environment such as a fire, the shock-absorbing and isolating component 2 can be prevented from being overheated and causing a decrease in elasticity, thereby affecting the shock-absorbing and isolating effect. The heat-insulating pad 4 plays a role in heat insulation to prevent the heat on the base plate 1 from being transferred to the shock-absorbing and isolating component 2. The glass fiber fireproof tube 32 has a heat-insulating effect to prevent the elasticity of the shock-absorbing rubber plate 22 from being reduced due to high temperature in a fire environment. The fiberglass fireproof tube 32 is wavy in shape. When vibrated, the shock-absorbing and isolating component 2 will deform to buffer and absorb energy. The wavy shape of the fiberglass fireproof tube 32 can provide the necessary material length for the deformation of the fiberglass fireproof tube 32, so that the fiberglass fireproof tube 32 can deform together with the shock-absorbing and isolating component 2. The spring 31 supports the fiberglass fireproof tube 32. The shaping tube 33 can keep the fiberglass fireproof tube 32 wavy. The asbestos layer 41 plays a role of heat insulation. Asbestos layers 41 are arranged between adjacent steel plates 42, which can improve the overall heat insulation effect of the insulation pad 4 and prevent heat from being transferred to the shock-absorbing and isolating component 2 through the substrate 1.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
