Description

Technical Field

[0001] The invention relates to the technical field of seismic isolation bearings, and in particular to a seismic isolation bearing insulation device. Background Art

[0002] After decades of development, seismic isolation technology has been applied to some extent in actual projects at home and abroad. Practice has proved that seismic isolation technology can effectively reduce the response of structures under earthquakes and significantly improve the toughness and seismic performance of structures. With the promulgation of the "Regulations on Seismic Management of Construction Projects", seismic isolation technology has shown an explosive growth trend.

[0003] Due to the vast geographical area of ​​my country, some areas are in extremely cold regions, and the temperature difference between day and night is large. The low temperature environment in Hebei, Shanxi, Inner Mongolia, Liaoning, Jilin, Heilongjiang, Shaanxi, Gansu, Qinghai, Xinjiang, Sichuan, Tibet and other places in my country reaches -42℃~-20℃. At the same time, due to the needs of building functions, some seismic isolation bearings are in open-air environments (such as the situation of setting up seismic isolation layers on the top of the overhead layer, etc.). Since most seismic isolation bearings (especially rubber bearings) use polymer materials such as rubber, synthetic rubber or polymer materials, the strain capacity of polymer materials such as rubber is reduced in low temperature environments, resulting in the seismic isolation bearings being unable to effectively adapt to the deformation of the structure. This will affect its shock absorption and seismic isolation performance, reduce the seismic effect, and make it difficult to use the seismic isolation bearings normally.

[0004] Therefore, the impact of low temperature on the performance of seismic isolation bearings cannot be ignored. In extremely cold areas, it is necessary to consider the insulation design of seismic isolation bearings so that they can function in low temperature environments. However, current designs rarely consider protective measures for seismic isolation bearings under outdoor environmental conditions in cold regions. Summary of the invention

[0005] The purpose of the present invention is to provide a seismic isolation bearing insulation device to address the problem that seismic isolation bearings in the background technology are difficult to use normally in low temperature environments, and current designs rarely consider protection measures for seismic isolation bearings under outdoor environmental conditions in cold areas.

[0006] In a first aspect, the present invention provides a seismic isolation bearing insulation device, comprising an outer insulation structure and an inner insulation structure arranged along the circumference of the bearing body, wherein the outer insulation structure abuts against the outer side of the inner insulation structure;

[0007] The outer thermal insulation structure and the inner thermal insulation structure can be deformed horizontally following the support body;

[0008] It also includes an intelligent heating system, which is located on the inner side of the inner insulation structure and is used to heat the support body.

[0009] The seismic isolation bearing insulation device described in the present application includes an outer insulation structure and an inner insulation structure. The outer insulation structure and the inner insulation structure are arranged along the circumference of the bearing body to isolate the bearing body from the outdoor environment. At the same time, an intelligent heating system is arranged on the inner side of the inner insulation structure. The bearing body is heated by the intelligent heating system to ensure that the bearing body can function normally in a low-temperature environment, thereby solving the problem of insufficient applicability of the bearing body under low-temperature conditions. Furthermore, the outer insulation structure and the inner insulation structure can deform horizontally following the bearing body, so as to achieve coordinated deformation of the inner and outer insulation structures and the bearing body, so that the inner and outer insulation structures can deform together with the bearing body under small and medium earthquakes, thereby making the inner and outer insulation structures less susceptible to damage and reducing the replacement frequency.

[0010] Preferably, the external thermal insulation structure comprises at least two vertically arranged first thermal insulation layers, and expansion joints are provided between adjacent first thermal insulation layers;

[0011] The inner thermal insulation structure is a laminated structure, and has an extension portion thereon, and the extension portion is filled into the expansion joint.

[0012] The external thermal insulation structure is at least two vertically arranged first thermal insulation layers, and expansion joints are provided between adjacent first thermal insulation layers. The expansion joints are used to separate and displace two adjacent first thermal insulation layers. When the support body moves horizontally, the two adjacent first thermal insulation layers can separate and move separately, so that the external thermal insulation structure can adapt to the horizontal deformation of the support body.

[0013] Furthermore, the internal insulation structure is a laminated structure, and when the support body moves horizontally, the laminated structure can adaptively deform horizontally to adapt to the horizontal deformation of the support body;

[0014] Furthermore, since the inner thermal insulation structure has an extension part, the extension part is filled into the expansion joint, and the expansion joint is filled by the extension part, so that two adjacent first thermal insulation layers are separated, and the functions of thermal insulation, filling and aesthetics are achieved.

[0015] Preferably, the first thermal insulation layer has an annular step on one side close to the expansion joint, and adjacent annular steps form a boss;

[0016] The outer side of the inner heat-insulating structure is provided with an annular groove, the extension portion is located in the annular groove, and the boss is embedded in the annular groove.

[0017] A boss is formed by adjacent annular steps of the first insulation layer, and the boss is embedded in the annular groove on the inner insulation structure. When the support body moves horizontally, the support body pushes the internal insulation structure, and the internal insulation structure drives the outer insulation structure to move together to ensure the consistency of the movement displacement of the inner and outer insulation structures.

[0018] Preferably, the first thermal insulation layer is assembled from at least two first thermal insulation blocks, and a clamp is sleeved on the outer wall of the first thermal insulation layer. The first thermal insulation layer is assembled from at least two first thermal insulation blocks fixed by the clamp. When the first thermal insulation layer is damaged during use, the clamp is opened, and then the old first thermal insulation block is removed and replaced with a new first thermal insulation block to form a new first thermal insulation layer. It is easy to install and disassemble and convenient to operate.

[0019] Preferably, the inner insulation structure is composed of at least two laminated insulation blocks;

[0020] The first thermal insulation layer is in contact with the laminated thermal insulation block, and the first joint seams between adjacent laminated thermal insulation blocks and the second joint seams between adjacent first thermal insulation blocks are offset from each other.

[0021] The inner insulation structure is composed of at least two laminated insulation blocks, which is convenient for installation and replacement. Furthermore, the first insulation layer is in contact with the laminated insulation block, that is, the laminated insulation block is clamped by the first insulation layer, so that the multiple laminated insulation blocks form the inner insulation structure, avoiding the need to fix the multiple laminated insulation blocks separately as a whole.

[0022] In addition, the first splicing seams between adjacent laminated insulation blocks and the second splicing seams between adjacent first insulation blocks are staggered with each other. The staggered design makes the splicing seams of the laminated insulation blocks and the first insulation blocks not directly overlap, thereby avoiding repeated alignment of the splicing seam lines, avoiding stress concentration at the seams of the first insulation blocks, and ensuring the stability of the first insulation layer.

[0023] Preferably, the intelligent heating system comprises electric blankets, and the electric blankets are arranged at intervals along the circumference of the support body.

[0024] Preferably, the electric blankets are arranged in vertical layers. By arranging the electric blankets in vertical layers, the electric blankets in two adjacent layers can be separated and displaced to adapt to the horizontal deformation of the support body.

[0025] Preferably, the intelligent heating system further comprises a temperature sensing device, which is connected to the electric blanket and is used to monitor the external temperature. The temperature sensing device is provided with a temperature sensing threshold, which triggers the electric blanket to heat when the threshold is exceeded.

[0026] In a second aspect, the present invention discloses a seismic isolation bearing, comprising the bearing body and the thermal insulation device described in the present application, wherein the outer thermal insulation structure and the inner thermal insulation structure are arranged circumferentially around the bearing body;

[0027] The support body comprises a lead core and a laminated rubber arranged on the lead core, and the electric blanket is arranged on the laminated rubber.

[0028] The seismic isolation bearing of the present application includes a bearing body, which includes a lead core and laminated rubber. Through the laminated rubber on the lead core, when an earthquake occurs, the laminated rubber can adaptively deform horizontally to reduce the seismic force. At the same time, the outer insulation structure and the inner insulation structure are arranged around the bearing body circumferentially to isolate the bearing body from the outdoor environment, and the outer insulation structure and the inner insulation structure can deform horizontally following the bearing body to achieve coordination of the deformation of the inner and outer insulation structures and the bearing body, so that the inner and outer insulation structures are not easily damaged and the replacement frequency is reduced. The bearing body is then heated by an electric heating blanket arranged on the laminated rubber to solve the problem of insufficient applicability of the bearing body under low temperature conditions, so that the seismic isolation bearing of the present application can be used normally in low temperature environments, thereby improving the scope of use of the seismic isolation bearing.

[0029] In a third aspect, the present invention discloses a construction method of a seismic isolation bearing insulation device, which is used to construct the insulation device of the present invention, comprising the following steps:

[0030] S1: Arranging an electric blanket on the support body;

[0031] S2: installing laminated insulation blocks along the circumference of the support body, and assembling the laminated insulation blocks to form the inner insulation structure;

[0032] S3: installing a first insulation block circumferentially outside the inner insulation structure, assembling the first insulation blocks to form the outer insulation structure, and fixing the outer insulation structure with a clamp.

Furthermore, the outer insulation structure and the inner insulation structure can deform horizontally following the bearing body, so as to achieve coordinated deformation of the inner and outer insulation structures and the bearing body, so that the inner and outer insulation structures deform together with the bearing body under small and medium earthquakes, thereby making the inner and outer insulation structures less susceptible to damage and reducing the replacement frequency.

[0053] Example 1

[0054] like Figure 1-Figure 5 As shown, this embodiment discloses a seismic isolation bearing insulation device, comprising an outer insulation structure 1 and an inner insulation structure 2 arranged along the circumference of a bearing body 10, wherein the outer insulation structure 1 abuts against the outer side of the inner insulation structure 2;

[0055] The outer thermal insulation structure 1 and the inner thermal insulation structure 2 can be deformed horizontally along with the support body 10;

[0056] It also includes an intelligent heating system, which is located on the inner side of the inner thermal insulation structure 2 and is used to heat the support body 10 .

[0057] The outer thermal insulation structure 1 and the inner thermal insulation structure 2 are arranged along the circumference of the support body 10 to isolate the support body 10 from the outdoor environment. At the same time, an intelligent heating system is arranged on the inner side of the inner thermal insulation structure 2. The support body 10 is heated by the intelligent heating system to ensure that the support body 10 can function normally in a low-temperature environment, thereby solving the problem of insufficient applicability of the support body 10 under low-temperature conditions. Furthermore, the outer thermal insulation structure 1 and the inner thermal insulation structure 2 can deform horizontally following the support body 10, so as to achieve coordinated deformation of the inner and outer thermal insulation structures and the support body 10, so that the inner and outer thermal insulation structures can deform together with the support body 10 under small and medium earthquakes, thereby making the inner and outer thermal insulation structures less susceptible to damage and reducing the replacement frequency.

[0058] In one or more embodiments, Figure 3 , Figure 5 As shown, the external thermal insulation structure 1 includes at least two vertically arranged first thermal insulation layers 11, and expansion joints 3 are provided between adjacent first thermal insulation layers 11;

[0059] like Figure 3 , Figure 4 As shown, the inner thermal insulation structure 2 is a laminated structure, and an extension portion 21 is provided on the inner thermal insulation structure 2 , and the extension portion 21 is filled into the expansion joint 3 .

[0060] The external thermal insulation structure 1 is composed of at least two vertically arranged first thermal insulation layers 11, and expansion joints 3 are provided between adjacent first thermal insulation layers 11. The expansion joints 3 are used to separate and displace two adjacent first thermal insulation layers 11. When the support body 10 moves horizontally, the two adjacent first thermal insulation layers 11 can separate and move separately, so that the external thermal insulation structure 1 can adapt to the horizontal deformation of the support body;

[0061] The expansion joint 3 can make the external thermal insulation structure 1 adapt to the deformation of the support body 10, so as not to hinder the isolation support from functioning and to prevent the external thermal insulation structure 1 from being damaged as much as possible.

[0062] Furthermore, the inner thermal insulation structure 2 is a laminated structure, and when the support body 10 moves horizontally, the laminated structure can adaptively deform horizontally to adapt to the horizontal deformation of the support body 10;

[0063] Furthermore, since the inner thermal insulation structure 2 has an extension portion, the extension portion 21 is filled into the expansion joint 3, and the expansion joint 3 is filled by the extension portion 21, so that two adjacent first thermal insulation layers 11 are separated, and the expansion joint 3 is filled and aesthetically pleasing.

[0064] In the present application, the external insulation structure 1 adopts a semi-rigid insulation material, such as a rock wool board.

[0065] In the present application, the inner insulation structure 2 adopts a flexible insulation material, such as embossed grid aluminum silicate foil, and multiple layers of aluminum foil are vertically stacked to form a laminated structure, wherein the multiple layers of aluminum foil are sequentially connected end to end to form a whole, so that the inner insulation structure 2 can not only be deformed in the horizontal direction, but also be a whole, which is convenient for installation and disassembly.

[0066] In this application, the thermal insulation material has a combustion grade of A and is hydrophobic.

[0067] In an optional embodiment, if Figure 5 As shown, the first thermal insulation layer 11 has an annular step 111 on one side close to the expansion joint 3, and adjacent annular steps 111 form a boss 112;

[0068] An annular groove 22 is formed on the outer side of the inner heat-insulating structure 2 , the extension portion 21 is located in the annular groove 22 , and the boss 112 is embedded in the annular groove 22 .

[0069] A boss 112 is formed by the adjacent annular steps 111 of the first thermal insulation layer 11, and the boss 112 is embedded in the annular groove 22 on the inner thermal insulation structure 2. When the support body 10 moves horizontally, the support body 10 pushes the inner thermal insulation structure 2, and the inner thermal insulation structure 2 drives the outer thermal insulation structure 1 to move together, so as to ensure the consistency of the movement displacement of the inner and outer thermal insulation structures.

[0070] In an optional embodiment, if Figure 7 As shown, the first insulation layer 11 is assembled from at least two first insulation blocks 101, and a clamp 114 is sleeved on the outer wall of the first insulation layer 11, wherein the clamp 114 is circumferentially arranged around the first insulation layer 11 to fix the plurality of first insulation blocks 101 together, as shown in FIG. Figure 3 .

[0071] The first insulation layer 11 is assembled by at least two first insulation blocks 101 fixed by a clamp 114. When the first insulation layer 11 is damaged during use, the clamp 114 is opened, and then the old first insulation block 101 is removed and replaced with a new first insulation block 101 to form a new first insulation layer 11. It is easy to install and disassemble and easy to operate.

[0072] In an optional embodiment, if Figure 7 As shown, the inner thermal insulation structure 2 is composed of at least two laminated thermal insulation blocks 201, which is convenient for installation and replacement;

[0073] The first thermal insulation layer 11 is in contact with the laminated thermal insulation block 201 , and the first joint seams 202 between adjacent laminated thermal insulation blocks 201 and the second joint seams 102 between adjacent first thermal insulation blocks 101 are offset from each other.

[0074] The first insulation layer 11 is in contact with the laminated insulation block 201, that is, the laminated insulation block 201 is clamped by the first insulation layer 11, so that the multiple laminated insulation blocks 201 form the inner insulation structure 2, avoiding the need to fix the multiple laminated insulation blocks 201 individually as a whole;

[0075] In addition, the first splicing seam between adjacent laminated insulation blocks 201 and the second splicing seam between adjacent first insulation blocks 101 are staggered with each other. The staggered design makes the splicing seam positions of the laminated insulation blocks 201 and the first insulation blocks 101 not directly overlap, thereby avoiding repeated alignment of the splicing seam lines, avoiding stress concentration at the joints of the first insulation blocks 101, and ensuring the stability of the first insulation layer 11.

[0076] In one or more embodiments, Figure 2 As shown, the intelligent heating system includes electric blankets 4, which are arranged at intervals along the circumference of the support body 10. The support body 10 is heated by arranging the electric blankets 4.

[0077] In an optional embodiment, the electric blankets 4 are arranged in vertical layers. By arranging the electric blankets 4 in vertical layers, the electric blankets 4 of two adjacent layers can be separated and staggered to adapt to the horizontal deformation of the support body 10;

[0078] Furthermore, the gap between two adjacent layers of electric blankets 4 is aligned with the expansion joint 3 on the external thermal insulation structure 1 , so that the electric blanket 4 does not restrict the horizontal displacement of the support body 10 .

[0079] In an optional embodiment, if Figure 2 As shown, the intelligent heating system also includes a temperature sensing device 5, which is connected to the electric blanket 4 and is used to monitor the external temperature. When the temperature sensing device 5 detects that the temperature is lower than the minimum temperature threshold, an alarm is triggered to start heating, and when the temperature is higher than the maximum temperature threshold, heating is stopped, so that the temperature can function in a low temperature environment of -20°C to 40°C.

[0080] In an optional implementation, the electric blanket 4 is powered by a solar energy reserve power source or a pre-buried cable.

[0081] In an optional embodiment, if Figure 6 As shown, an L-shaped plate 113 is provided at the annular step 111 of the outer thermal insulation structure 1, and a portion of the inner thermal insulation structure 2 is bonded to the L-shaped plate 113, so that the outer thermal insulation structure 1 and the inner thermal insulation structure 2 are connected together.

[0082] Example 2

[0083] On the basis of Example 1, Figure 1 , Figure 2As shown, in this embodiment, an isolation bearing insulation device, the outer insulation structure 1 and the inner insulation structure 2 are both rectangular structures, which are equal to the cross-section of the pier 40, so that after the insulation device is installed on the existing isolation bearing of the pier 40, the structure is beautiful and elegant.

[0084] In an optional embodiment, if Figure 2 As shown, there are four triangular areas 6 between the inner thermal insulation structure 2 and the support body 10, the electric blanket 4 is located in the triangular area 6, and the electric blanket 4 is arranged on the support body 10, and the middle part of each side of the inner thermal insulation structure 2 is in contact with the support body 10;

[0085] A temperature sensing device 5 is also provided in each triangular area 6 , and the temperature sensing device 5 is used to monitor the external temperature. Furthermore, a lightning protection grounding wire 7 is provided in at least one triangular area 6 .

[0086] In an optional implementation, a displacement sensor and a mechanical sensor are installed in the triangular area 6 to measure the force and displacement of the seismic isolation bearing caused by an earthquake.

[0087] Example 3

[0088] On the basis of Example 1 or Example 2, Figure 1 , Figure 2 As shown, this embodiment discloses a seismic isolation bearing, comprising a bearing body 10 and a heat preservation device as in Embodiment 1 or Embodiment 2, wherein an outer heat preservation structure 1 and an inner heat preservation structure 2 are circumferentially arranged around the bearing body 10;

[0089] The support body 10 includes a lead core 20 and a laminated rubber 30 disposed on the lead core 20 , and the electric blanket 4 is arranged on the laminated rubber 30 .

[0090] By arranging the laminated rubber 30 on the lead core 20, when an earthquake occurs, the laminated rubber 30 can adaptively deform horizontally to reduce the seismic force. At the same time, the outer insulation structure 1 and the inner insulation structure 2 are arranged circumferentially around the support body 10 to isolate the support body 10 from the outdoor environment, and the outer insulation structure 1 and the inner insulation structure 2 can deform horizontally following the support body 10 to achieve coordinated deformation of the inner and outer insulation structures and the support body 10, so that the inner and outer insulation structures are not easily damaged and the replacement frequency is reduced. The support body 10 is then heated by the electric blanket 4 arranged on the laminated rubber 30 to solve the problem of insufficient applicability of the support body 10 under low temperature conditions, so that the seismic isolation bearing of the present application can be used normally in a low temperature environment, thereby improving the scope of use of the seismic isolation bearing.

[0091] In this embodiment, Figure 1As shown, the pier 40 is divided into an upper pier and a lower pier, and the support body 10 is installed between the upper pier and the lower pier. Furthermore, a sleeve 70 is connected to the support positioning plate 60, and the sleeve 70 is pre-buried in the pier 40. The support flange plate 50 is fixed to the support positioning plate 60 by a support bolt 80, wherein the support bolt 80 passes through the support flange plate 50 and is connected in the sleeve 70;

[0092] like Figure 3 , Figure 5 As shown, when the external insulation structure 1 includes two first insulation layers 11, the internal insulation structure 2 is firstly arranged around the circumference of the support 10 body, and then the internal insulation structure 2 is surrounded by the two first insulation layers 11. The junction between the upper and lower piers and the first insulation layers 11 is sealed and aesthetically treated with an aesthetically pleasing annular insulation sealing strip.

[0093] Example 4

[0094] On the basis of Example 1 or 2, this embodiment discloses a construction method of a seismic isolation bearing insulation device, and the construction of the insulation device as described in Example 1 includes the following steps:

[0095] S1: Arrange the electric blanket 4 on the support body 10;

[0096] S2: Install the laminated insulation blocks 201 along the circumference of the support body 10, and assemble the laminated insulation blocks 201 to form an inner insulation structure 2;

[0097] S3: Install the first insulation block 101 circumferentially on the outer side of the inner insulation structure 2 , assemble the first insulation blocks 101 to form the outer insulation structure 1 , and fix the outer insulation structure 1 with a clamp 114 .

[0098] The inner insulation structure 2 is formed by a plurality of laminated insulation blocks 201, which is convenient for the installation and disassembly of the inner insulation structure 2. The outer insulation structure 1 is formed by assembling a plurality of first insulation blocks 101 and then fixed by a clamp 114, which is convenient for the installation and disassembly of the outer insulation structure 1. The construction method of the insulation device of this embodiment installs the electric blanket 4, the inner insulation structure 2 and the outer insulation structure 1 on the existing seismic isolation support, thereby insulating the existing seismic isolation support, so that the existing seismic isolation support can be used normally in a low temperature environment.

[0099] In an optional implementation manner, the power cables required by the present application are pre-buried at designated points during the civil construction of the upper and lower piers, and sufficient displacement and deformation conditions are reserved according to the design requirements;

[0100] In an optional implementation, the installation of the thermal insulation device is implemented after the construction of the seismic isolation support and the upper seismic isolation layer is completed and the formwork is removed, or it can be implemented after the upper main body is completed.
