Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an installation structure and a construction method for a supporting platform of an electromechanical seismic isolation module with a super-large deformation. Background Art

[0002] my country is a country prone to earthquakes, and earthquakes are distributed over a wide area. Due to the significant advantages of seismic isolation technology, seismic isolation technology is regarded as the most effective measure to improve the resilience of buildings. Seismic isolation technology separates the upper and lower structures of buildings, and absorbs earthquake energy by establishing an isolation layer, reducing the damage to the upper structure caused by the earthquake, and realizing the principle of normal use after the earthquake. However, a large amount of experience in earthquake disasters has shown that the seismic isolation layer deforms greatly under the action of an earthquake, and the number and types of pipes inside it are large. Among them, the pipes passing through the seismic isolation layer will bend or axially deform due to the displacement of the seismic isolation layer. If only ordinary pipes are used for the pipes passing through the seismic isolation layer, the ordinary pipes will be damaged by the earthquake, and the normal operation of the electromechanical system after the earthquake cannot be guaranteed. It may also cause various secondary disasters and cause greater economic losses. It can be seen that it is very important to reasonably design and construct seismic isolation of pipes in seismic isolation buildings.

[0003] Many codes issued by my country also mention relevant measures for flexible pipes, such as Article 3.1.8 of Code for Seismic Design of Mechanical and Electrical Engineering of Buildings (GB 50981-2014), Article 5.4.1 of Code for Construction and Acceptance of Seismic Isolation Engineering of Buildings (JGJ 360-2015), and Article 12.1.3 of Code for Seismic Design of Buildings (GB 50011-2010, 2016 edition). Seismic isolation technology for water supply and drainage pipes with deformation exceeding 700 mm has not been studied in depth. In Appendix A of JG / T541-2017 "Flexible Pipes for Seismic Isolation of Buildings", the allowable displacement parameters of seismic isolation hoses only list 150mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, 600mm, 650mm and 700mm. There is no design for seismic isolation hoses with large deformations greater than or equal to 800mm. At present, the main problems for seismic isolation modules with large deformations are:

[0004] (1) The length of the seismic isolation hose with a deformation of 800 mm is a first-time design, and there are no relevant mature design cases and reference materials;

[0005] (2) The seismic isolation module is too long and the installation space is limited;

[0006] (3) This type of seismic isolation module with extremely large deformation is extremely long and easily deformed when installed horizontally, resulting in poor appearance and easy shaking during operation.

[0007] When the design length of a single seismic isolation hose is between 1.6 meters and 2.6 meters, two seismic isolation hoses are usually connected with a connecting elbow (L-type connection) when installed horizontally (hereinafter referred to as this structure as a pipe seismic isolation module). The seismic isolation hose has a small rigidity, and it is easy to sag in the middle of the seismic isolation hose when installed horizontally. The flange part is severely stressed, and the service life is greatly reduced. If the seismic isolation hose uses a hanging chain or a hanging rod to slow down the sagging of the hose, because the hanging rod or the hanging chain usually slides in a slide rail or on a turntable, the movement trajectory of the seismic isolation hose will be greatly restricted during an earthquake, and it is difficult to give full play to the seismic isolation capacity of the seismic isolation hose. In addition, the strength and durability of the hanging chain or the hanging rod are relatively poor, and they are easily damaged or stuck during an earthquake. They are prone to aging and poor appearance. Summary of the invention

[0008] In order to overcome the defects of the prior art, an installation structure and construction method of a support platform for an ultra-large deformation electromechanical seismic isolation module is provided to solve the problem that the 800mm ultra-large deformation seismic isolation hose is difficult to install in a limited space using the traditional installation method and is easily damaged or stuck during an earthquake.

[0013] An elastic member for pulling the second pulley toward the outer curved side of the connecting elbow is installed on the supporting platform.

[0014] Furthermore, the pipes in the non-seismic isolation zone are suspended from the building ceiling in the non-seismic isolation zone through brackets, and the design elevation of the support platform is lower than the design elevation of the brackets.

[0015] Furthermore, the elevation difference between the support platform and the bracket is 100 mm.

[0016] Furthermore, the first pulley includes a first base and two rows of first rollers installed on the first base, the first base is arranged along the row direction of the first seismic isolation hose or the second seismic isolation hose, and the two rows of first rollers are arranged along the width direction of the first base.

[0017] Furthermore, there are a plurality of the first pulleys, and the plurality of the first pulleys are arranged at intervals along the length direction of the first seismic isolation hose or the second seismic isolation hose, and a distance between two adjacent first pulleys is less than 700 mm.

[0018] Furthermore, the second pulley includes a second base and two rows of second rollers installed on the second base, the first base is arranged along the row direction of the plurality of connecting elbows, and the two rows of second rollers are arranged along the width direction of the second base.

[0019] Furthermore, the outer edge of the support platform is suspended on the building ceiling of the seismic isolation zone through multiple suspension rods, and the multiple suspension rods are arranged at intervals along the circumferential direction of the outer edge of the support platform. The elastic member is connected to a suspension rod and the second pulley.

[0020] Furthermore, the elastic member is a spring.

[0021] The present invention provides a construction method for an installation structure of a super-large deformation electromechanical seismic isolation module support platform, comprising the following steps:

[0022] The supporting platform is suspended from the building ceiling in the seismic isolation area;

[0023] A plurality of first pulleys and a second pulley are movably arranged on the support platform, so that the plurality of first pulleys on one side of the support platform are arranged along a first horizontal direction, and the plurality of first pulleys on the other side of the support platform are arranged along a second horizontal direction, and the second pulley is movably arranged in the middle of the support platform, and the second pulley is arranged along the row direction of the plurality of connecting elbows;

[0024] A plurality of first seismic isolation hoses arranged side by side are fixedly mounted on a plurality of the first pulleys on one side of the support platform, a plurality of second seismic isolation hoses arranged side by side are fixedly mounted on a plurality of the first pulleys on the other side of the support platform, and a plurality of connecting elbows arranged side by side are respectively connected to the other ends of the first seismic isolation hoses and the second seismic isolation hoses and placed on the second pulleys;

It is a "planar dynamic structure", which subverts the traditional "dynamic structure of the facade" in "moving". The traditional structure "moving" is the hanger or chain + seismic isolation module, which is a "dynamic structure of the facade". The installation structure of the support platform of the electromechanical seismic isolation module with super large deformation of the present invention reduces the impact on the vertical space.

[0029] The seismic isolation module of the installation structure of the ultra-large deformation electromechanical seismic isolation module support platform of the present invention can slide relatively freely on the pulley. The pulley has a larger range of movement and a freer direction of movement, which can give full play to the deformation capacity of the seismic isolation module, thus changing the current situation in which the seismic isolation module of the traditional method cannot give full play to the seismic isolation capacity.

[0030] The seismic isolation hose of the mounting structure of the support platform of the super-deformation electromechanical seismic isolation module of the present invention is protected by the support platform and supported by a pulley, which overturns the original practice of suspending the seismic isolation module with a hanging chain or a hanging rod, and greatly improves the safety and durability of the seismic isolation module.

[0036] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] Reference Figures 1 to 4 As shown, the present invention provides an installation structure of a support platform for an electromechanical seismic isolation module with a super-large deformation, comprising: a support platform 1, a first pulley 2, a second pulley 3, and an elastic member 4.

[0039] In this embodiment, an isolation gap a is formed between the building ceiling 8 in the isolation zone and the ceiling 9 in the non-isolation zone. The support platform 1 is suspended on one side of the building ceiling 8 in the isolation zone close to the isolation gap. The support platform is pentagonal.

[0040] The seismic isolation module includes a plurality of L-shaped connecting elbows arranged side by side and seismic isolation hoses connected to both ends of the L-shaped connecting elbows. Seismic isolation hoses are connected to both ends of each row of L-shaped connecting elbows. One end of a row of seismic isolation hoses away from the L-shaped connecting elbows is connected to a common pipeline in a non-seismic isolation area, and both are connected by flanges; one end of another row of seismic isolation hoses away from the L-shaped connecting elbows is connected to a common pipeline in a seismic isolation area, and both are connected by flanges.

[0041] There are multiple first pulleys. There are multiple first pulleys, and the multiple first pulleys are arranged at intervals along the length direction of the first seismic isolation hose or the second seismic isolation hose, and the distance between two adjacent first pulleys is less than 700 mm.

[0042] The number of the second pulley is one.

[0043] Wherein, a plurality of first pulleys 2 are movably arranged on both sides of the support platform 1. In this embodiment, two first pulleys are arranged on each side of the support platform.

[0044] Specifically, the plurality of first pulleys 2 on one side of the support platform 1 are arranged along the first horizontal direction. The plurality of first pulleys 2 on one side of the support platform 1 are fixed with a plurality of first seismic isolation hoses 51 arranged side by side. The first seismic isolation hoses 51 are arranged along the first horizontal direction.

[0045] The multiple first pulleys 2 on the other side of the support platform 1 are arranged along the second horizontal direction. The second horizontal direction is arranged at an angle to the first horizontal direction. The multiple first pulleys 2 on the other side of the support platform 1 are fixed with multiple second seismic isolation hoses 52 arranged side by side. The second seismic isolation hoses 52 are arranged along the second horizontal direction. One end of the second seismic isolation hose 52 is connected to the pipe 7 in the non-seismic isolation area.

[0046] In this embodiment, the seismic isolation hose is connected to the elbow via a flange, and the seismic isolation hose is connected to a common pipeline in a non-seismic isolation area via a flange.

[0047] The second pulley 3 is movably arranged in the middle of the support platform 1. The second pulley 3 is fixed with a plurality of connecting elbows 6 arranged side by side. The two ends of the connecting elbows 6 are respectively connected to the other ends of the first seismic isolation hose 51 and the second seismic isolation hose 52 through pipe clamps. The second pulley 3 is arranged along the row direction of the plurality of connecting elbows 6.

[0048] In this embodiment, the first horizontal direction is perpendicular to the second horizontal direction, and the second pulley is arranged along the third horizontal direction, that is, the third horizontal direction is the setting direction of the bisector of the angle between the first horizontal direction and the second horizontal direction.

[0049] The elastic member 4 is mounted on the supporting platform 1. The elastic member 4 is used to pull the second pulley 3 toward the outer curved side of the connecting elbow 6.

[0050] In this embodiment, the pipe 7 in the non-seismic isolation zone is suspended from the building ceiling 9 in the non-seismic isolation zone by a bracket 71. The design elevation of the support platform 1 is lower than the design elevation of the bracket 71. During an earthquake, the bracket in the non-seismic isolation zone will not collide with the support platform in the seismic isolation zone in the horizontal space.

[0051] As a preferred implementation, the elevation difference between the support platform 1 and the bracket 71 is 100 mm.

[0052] In this embodiment, the combination of the first pulley and the second pulley is similar, and the first pulley is used as an example in the following figure ( Figure 4 ) specifically describe its structural composition.

[0053] The first pulley 2 includes a first base 21 and two rows of first rollers 22 mounted on the first base. The first base is arranged along the arrangement direction of the first seismic isolation hose 51 or the second seismic isolation hose 52. The two rows of first rollers are arranged along the width direction of the first base.

[0054] The second pulley 3 includes a second base and two rows of second rollers mounted on the second base. The first base is arranged along the row direction of the plurality of connecting elbows 6. The two rows of second rollers are arranged along the width direction of the second base.

[0055] The outer edge of the support platform 1 is suspended on the building ceiling of the seismic isolation zone through a plurality of suspension rods 11. The plurality of suspension rods 11 are arranged at intervals along the circumferential direction of the outer edge of the support platform 1. The elastic member 4 is connected to a suspension rod 11 and the second pulley 3.

[0056] As a preferred embodiment, the elastic member 4 is a spring. The use of a spring as the elastic member can make the seismic isolation module in a straight state rather than a bent state at ordinary times, thereby improving the visual performance of the seismic isolation module.

[0057] In this embodiment, the connecting elbow and the two seismic isolation hoses are used as a complete seismic isolation module. The function of the spring is to put the second pulley and the seismic isolation module fixed on the second pulley in a slightly stressed state, so that the seismic isolation module can maintain a good shape in non-earthquake conditions (90 degrees at the connecting elbow and the rest of the parts are in a straight line state). During an earthquake, the spring can slightly absorb the energy of the earthquake and reduce the shaking of the seismic isolation module. After the earthquake, the spring can quickly restore the seismic isolation module to its original state.

[0058] When the installation space is limited and the isolation modules need to be arranged on both sides, the isolation support platform can be made into a double-layer structure (the cantilever platform + pulley + spring structure + isolation module are all independent layers, but the platform columns can be shared). The columns and cantilever platform of this structure are relatively static. During an earthquake, only the pulley + isolation module + spring are moving, which subverts the traditional structure of the traditional isolation module where the suspension chain or suspension rod + isolation module are all moving, which "occupies vertical space".

[0059] The installation structure of the ultra-large deformation electromechanical seismic isolation module support platform of the present invention has the scalability to be made into double-layer or multi-layer structures, and has a stronger seismic isolation capability, breaking the current situation that the traditional pipeline seismic support system has a small displacement capacity and is difficult to be made into a multi-layer structure.

[0060] The present invention provides a construction method for an installation structure of a super-large deformation electromechanical seismic isolation module support platform, comprising the following steps:

[0061] S1. Hang the supporting platform 1 on the building ceiling in the seismic isolation area.

[0062] S2. Moveably set a plurality of first pulleys 2 and a second pulley 3 on the support platform 1, so that the plurality of first pulleys 2 on one side of the support platform 1 are set along the first horizontal direction, and the plurality of first pulleys 2 on the other side of the support platform 1 are set along the second horizontal direction, and the second pulley 3 is movably set in the middle of the support platform 1, and the second pulley 3 is set along the row direction of the plurality of connecting elbows 6.

[0063] S3. Fix the multiple first seismic isolation hoses 51 arranged side by side on the multiple first pulleys 2 on one side of the supporting platform 1, fix the multiple second seismic isolation hoses 52 arranged side by side on the multiple first pulleys 2 on the other side of the supporting platform 1, and respectively connect the multiple connecting elbows 6 arranged side by side to the other ends of the first seismic isolation hoses 51 and the second seismic isolation hoses 52 and place them on the second pulley 3.

[0064] S4. Connect one end of the second seismic isolation hose 52 to the pipeline in the non-seismic isolation area.

[0065] S5 , fix the first seismic isolation hose 51 and the second seismic isolation hose 52 on the first pulley 2 , and fix the connecting elbow 6 on the second pulley 3 .

[0066] S6, installing the elastic member 4 on the supporting platform 1 and the second pulley 3 to pull the second pulley 3 toward the outer curved side of the connecting elbow 6.

[0067] Taking the project in which the deformation of the seismic isolation hose is 800 mm as an example, the installation structure of the support platform of the electromechanical seismic isolation module with super-large deformation of the present invention is specifically described.

[0068] The bracket of the non-seismic isolation zone is installed in the non-seismic isolation zone. It is installed at the edge of the seismic isolation zone and is made of No. 6 channel steel. The length of the bracket extending into the seismic isolation joint a is 450mm, and the length of the pipe in the non-seismic isolation zone extending into the seismic isolation joint is 700mm.

[0069] A support platform is installed in the seismic isolation area. The support platform is made into a pentagon, and the bottom crossbeam of the support platform is made of No. 10 channel steel. The hanger on the support platform is close to the seismic isolation joint, and the support platform extends into the seismic isolation joint by 500mm. The height difference with the bracket in the seismic isolation area is 40mm, and the axial distance between the hanger and the bracket is greater than 800mm, so that during an earthquake, the bracket and the support platform will not collide in the horizontal space.

[0070] Install ordinary pipes and isolation modules in non-isolated areas.

[0071] The seismic isolation module uses four parallel L-shaped connecting elbows, and four first seismic isolation hoses and four second seismic isolation hoses connected to the L-shaped connecting elbows. The length of ordinary pipes in the non-seismic isolation area extending into the seismic isolation joint is 700mm. The second seismic isolation hose extends into the seismic isolation joint by 100mm. The seismic isolation module is 100mm higher than the installation height of the support platform, and is first supported by the second pulley and the first pulley. The ordinary pipes in the non-seismic isolation area are connected to the second seismic isolation hoses with flanges. The ordinary pipes in the seismic isolation area are connected to the first seismic isolation hoses with flanges. The ordinary pipes in the non-seismic isolation area are fixed with brackets 9, and the height difference between the brackets and the support platform is 100mm.

[0072] One second pulley and four first pulleys are used, wherein the second pulley is used to fix and support the L-shaped connecting elbow in the seismic isolation module, and the other four first pulleys 4 are arranged below the first seismic isolation hose and the second seismic isolation hose, respectively, and the length of the first pulley is 50mm wider on both sides of the outer edge of the installation width of the first seismic isolation hose and the second seismic isolation hose in a row. The height of the second pulley and the first pulley are both 100mm, which can ensure that the seismic isolation module in the seismic isolation area and the ordinary pipes in the non-seismic isolation area can be installed at the same height. The second pulley and the first pulley both use 4mm thick steel plates as the support surface of the seismic isolation hose, that is, the base. 1.5-inch universal wheels (i.e. rollers) are installed under the base, and the universal wheels are arranged in two rows in the long side direction of the base. The long-side spacing of the universal wheels is 440mm, and the short-side spacing is 230mm.

[0073] The first pulley is arranged at 1 / 3 and 2 / 3 of the first isolation hose and the second isolation hose respectively; a spring with a normal tension of 2 kg and a tension of 16 kg at maximum deformation is installed at the outer corner of the second pulley. The other end of the spring is fixed on the suspension rod that is 135° on both sides of the outer corner of the second pulley.

[0074] A bracket is installed in the non-isolation area to allow ordinary pipes to extend into the isolation joint, and a suspended support platform (consisting of a support platform + pulley + elastic parts) of the isolation module is installed in the isolation area. The vertical distance between the table top of the support platform in the isolation area and the bracket in the non-isolation area is 40mm (greater than the longitudinal wave amplitude of the earthquake of 20mm), which effectively prevents the collision between the isolation platform in the isolation area and the fixed bracket in the non-isolation area.

[0075] The width of the pulley is 280mm. The edge spacing between the pulleys is less than 700mm. Due to the support of the pulley, the seismic isolation module in the seismic isolation zone has almost no sagging phenomenon. The pulley and the seismic isolation module are fixed with pipe clamps.

[0076] The seismic isolation hose can slide relatively freely on the platform under the action of the pulley, which can give full play to the deformation capacity of the seismic isolation hose. This structure subverts the practice of traditional structures where the suspension chain or suspension rod will weaken the deformation capacity of the seismic isolation short tube. The spring fixed on the second pulley and the platform suspension rod can also restore the seismic isolation module to its original state after an earthquake.

[0077] When the installation space is limited and the seismic isolation modules need to be arranged on both sides, the seismic isolation support platform can be made into a double-layer structure (the support platform + pulley + spring structure + seismic isolation module are all two independent layers, but the platform hanger can be shared).

[0078] The installation structure of the support platform of the super-large deformation electromechanical seismic isolation module of the present invention is a "support platform + cantilever platform + pulley + elastic member" structure, and the "moving" parts are the seismic isolation module + pulley + elastic member, and the cantilever bracket and the suspension rod of the support platform are stationary, which is a "planar dynamic structure", subverting the traditional "dynamic structure of the facade" in the "moving" approach. The traditional structure "moving" is the suspension rod or suspension chain + seismic isolation module, which is a "dynamic structure of the facade". The installation structure of the support platform of the super-large deformation electromechanical seismic isolation module of the present invention reduces the impact on the vertical space.

[0079] The seismic isolation module of the installation structure of the ultra-large deformation electromechanical seismic isolation module support platform of the present invention can slide relatively freely on the pulley. The pulley has a larger range of movement and a freer direction of movement, which can give full play to the deformation capacity of the seismic isolation module, thus changing the current situation in which the seismic isolation module of the traditional method cannot give full play to the seismic isolation capacity.

[0080] The seismic isolation hose of the mounting structure of the support platform of the super-deformation electromechanical seismic isolation module of the present invention is protected by the support platform and supported by a pulley, which overturns the original practice of suspending the seismic isolation module with a hanging chain or a hanging rod, and greatly improves the safety and durability of the seismic isolation module.

[0081] The installation structure of the support platform for the super-large deformation electromechanical seismic isolation module of the present invention is suitable for the horizontal installation of seismic isolation modules with a deformation of not less than 800 mm, filling the gap of the lack of mature cases for the horizontal installation of super-large deformation seismic isolation modules. The distance between each support point in the installation structure of the support platform for the super-large deformation electromechanical seismic isolation module of the present invention is less than 700 mm, which can effectively prevent the seismic isolation module from sagging, which is different from the traditional anti-seismic support system (which cannot prevent the seismic isolation module from sagging).

[0082] The elastic member in the mounting structure of the supporting platform of the super-deformation electromechanical seismic isolation module of the present invention can partially absorb the seismic energy and the impact and vibration energy of the pipeline medium, and can make the seismic isolation module relatively still (keep the module in a straight state to improve the appearance) and automatically return to the original state after the earthquake.

[0083] The "dynamic" structural part of the installation structure of the ultra-large deformation electromechanical seismic isolation module support platform of the present invention is in the plane and does not require a high vertical space; while the traditional seismic support system is a "vertical" dynamic structure. If the traditional seismic support system is to be transformed into this ultra-large displacement seismic isolation support system, it is because the traditional seismic support is designed for seismic resistance, not for seismic isolation modules. When the seismic support system is modified and used for seismic isolation modules, because the seismic support system is too complex and has weak deformation ability, in order to meet the requirement of 800mm universal deformation, the installation space needs to be particularly large and the structure is particularly complex. In addition, the stress generated by the seismic support system is too large, and either the pipe will be damaged, the pipe clamp will be damaged, or the seismic isolation module will be damaged. It cannot meet the requirements of the large universal displacement of the seismic isolation module and cannot be damaged and automatically restore to its original state.

[0084] The installation structure of the support platform of the super-large deformation electromechanical seismic isolation module of the present invention solves the quality risks of horizontal installation of super-large deformation seismic isolation modules, can give full play to the deformation capacity of the seismic isolation modules, can reduce the encroachment on vertical space, solves the design and construction difficulties of horizontal installation of super-large deformation seismic isolation modules, reduces operation and maintenance costs, and improves the safety and durability of the pipeline seismic isolation system.

[0085] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
