The structure includes a seismic isolation layer, a seismic isolation base plate, and a reverse beam. The seismic isolation layer is installed on the building structure piers, and the reverse beams connect the building structure piers. A seismic isolation base plate is installed at the bottom of the seismic isolation layer, and the base plate has several pre-reserved holes. The reverse beams have several pre-reserved holes. The beneficial effects of this invention are: The pre-reserved holes on the reverse beams allow for the arrangement of air conditioning condensate pipes and fire-fighting main pipes within the reverse beams, avoiding the occupation of the limited space in the seismic isolation layer by these pipes and preventing collisions between these pipes and other pipes within the seismic isolation layer.

Description

Technical Field

[0001] This invention relates to the field of construction engineering technology, specifically to a seismic isolation structure and method for utilizing the net height space in a high-level seismic isolation system for buildings. Background Technology

[0002] Using high-level seismic isolation technology can reduce the seismic fortification intensity of the superstructure, thereby reducing the project cost. However, high-level seismic isolation occupies a portion of the building's above-ground clear height, thus reducing the above-ground clear height.

[0003] For example, Chinese patent (publication number: CN104482343B) discloses an installation method for flexible connecting pipes in seismic isolation buildings. The flexible connecting pipe includes a corrugated pipe and a joint connected to the end of the corrugated pipe. A mesh sleeve is fitted onto the outer side of the corrugated pipe, and a mesh sleeve clamping ring is provided at the connection between the mesh sleeve and the joint. A circular thermoplastic rubber gasket is provided on the inner side of the corrugated pipe. This flexible connecting pipe is suitable for seismic isolation buildings. The construction method includes the following steps in sequence: 1) determining the net height of the isolation layer, 2) installing the isolation layer pipe, 3) installing the fixing frame, and 4) installing the flexible connecting pipe. This flexible connecting pipe has a large deformation capacity, high tensile strength, and is easy to clean of accumulated residues inside. The construction method solves the problems of preventing deformation of the isolation layer pipe during earthquakes and how to achieve flexible pipe connections. It is easy to implement, improves the overall post-earthquake safety of seismic isolation buildings, avoids secondary disasters caused by damage to the isolation layer pipe during earthquakes, and achieves the expected effect of seismic isolation buildings.

[0004] Existing technologies only allow vertical pipelines to pass through or make simple pipeline routing changes through vibration isolation layers. At the same time, in order to ensure convenient maintenance, the height of the vibration isolation layer must also be guaranteed. As a result, existing technologies make the vibration isolation layer occupy a large portion of the overall building height.

[0005] Therefore, it is necessary to propose a seismic isolation structure and method that utilizes the net height space under a high-level seismic isolation system for buildings to address the above-mentioned problems. Summary of the Invention

There is a distance of 200-500mm between the reserved hole on the slab and the inverted beam (the size of the reserved hole on the slab and the distance between the reserved hole and the surrounding beam edge are adjusted according to the column span).

[0012] Preferably, the pre-reserved holes on the plate are sealed with gypsum board, leaving a 10mm gap on the side to facilitate subsequent maintenance and ensure the appearance of the vibration isolation base plate.

[0013] Preferably, the pre-drilled holes on the plate are for air conditioning condenser pipes and fire sprinkler pipes to pass through.

[0014] Preferably, the steel sleeve with pre-drilled holes on the beam is used for pre-drilling and reinforcement of the openings.

[0015] Preferably, the specific location of the reserved holes on the beam is reserved on the inverted beam in conjunction with the arrangement of electromechanical pipelines.

[0035] like Figure 1 and combined Figures 2 to 5 As shown, a seismic isolation structure for utilizing the net height space under a high-level seismic isolation system for buildings includes a seismic isolation layer 1, a seismic isolation base plate 2, and a reverse beam 3. The seismic isolation layer 1 is installed on the building structure piers 4, and the reverse beam 3 is connected between the building structure piers 4. The seismic isolation base plate 2 is installed at the lower part of the seismic isolation layer 1. The seismic isolation base plate 2 is provided with a number of reserved holes 5 on the plate, and the reverse beam 3 is provided with a number of reserved holes 6 on the beam.

[0036] Furthermore, the vibration isolation layer 1 is used to arrange electromechanical pipelines 7.

[0037] Furthermore, the electromechanical pipeline 7 includes air conditioning condenser pipes, fire sprinkler pipes, and cable pipelines.

[0038] Furthermore, the pre-reserved holes 5 on the plate are located at the four corners of the seismic isolation base plate 2, and the pre-reserved holes 5 on the plate are square.

[0039] Furthermore, the length of the reserved hole 5 on the slab is 2~3m and the width is 1.5~2m. There is a distance of 200~500mm between the reserved hole 5 on the slab and the inverted beam 3 (the size of the reserved hole 5 on the slab and the distance between the reserved hole 5 on the slab and the surrounding inverted beam 3 are adjusted according to the column span).

[0040] Furthermore, the pre-reserved hole 5 on the plate is sealed with gypsum board, leaving a 10mm gap on the side to facilitate subsequent maintenance and ensure the appearance of the vibration isolation base plate.

[0041] Furthermore, the pre-drilled hole 5 on the plate is used for the air conditioning condenser pipe and the fire sprinkler pipe to pass through.

[0042] Furthermore, the reserved holes 6 on the beam are reserved and reinforced using steel sleeves.

[0043] Furthermore, the specific location of the reserved hole 6 on the beam is reserved on the inverted beam 3 in conjunction with the arrangement of electromechanical pipelines.

[0044] A method for utilizing the clear height space in a high-level seismic isolation system for buildings, comprising the following steps:

[0045] S1. A vibration isolation base plate 2 is installed at the bottom of the vibration isolation layer 1, and pre-reserved holes 5 are made on the plate at all four corners of the vibration isolation base plate 2.

[0046] S2. Set a pre-drilled hole 6 on the inverted beam 3;

[0047] S3, air conditioning condenser pipes, fire sprinkler pipes and cable pipelines are arranged in vibration isolation layer 1 and pass through the reserved holes 5 on the slab and the reserved holes 6 on the beam;

[0048] S4. After the arrangement is completed, the pre-reserved hole 5 on the plate is sealed with gypsum board, leaving a 10mm gap on the side to facilitate subsequent maintenance and ensure the appearance of the seismic isolation base plate.

[0049] Compared with the prior art, the present invention has the following advantages:

[0050] (1) The present invention realizes the arrangement of air conditioning condensate pipe and fire protection main pipe in the inverted beam by pre-reserved holes on the beam, avoiding the pipe from occupying the limited space of the vibration isolation layer, and avoiding the possibility of the pipe colliding with other pipes in the vibration isolation layer; the pre-reserved holes realize the requirements for subsequent maintenance of pipe network in the vibration isolation layer.

[0051] (2) The present invention reduces the height of the vibration isolation layer and raises the height of the first floor by pre-reserving holes on the slab, pre-reserving holes on the beam and arranging electromechanical pipelines, while keeping the total building height unchanged, so as to achieve a better building user experience.

[0052] (3) The present invention avoids collisions between electromechanical pipelines 7 through reasonable pipe arrangement, saves space of vibration isolation layer 1, and ensures the requirements of on-site construction and subsequent maintenance.

[0053] The pre-reserved holes 5 on the slab are set on the seismic isolation base slab 2 and distributed on the four corners of the seismic isolation base slab 2. The pre-reserved holes 6 on the beam are pre-reserved holes on the inverted beam 3 at the bottom of the vibration isolation layer 1. They are mainly used to pass through the air conditioning condenser pipes and fire sprinkler pipes. The inverted beam 3 is set in the area where a larger clearance is required at the bottom. The pipe arrangement method adopts a reasonable pipe arrangement principle and method to arrange all the electromechanical pipelines 7 on the first floor inside the vibration isolation layer 1, increasing the clear height space of the first floor and making full use of the vibration isolation layer 1.

[0054] The pre-reserved holes 5 are located on the seismic isolation base slab 2, distributed across each slab 2 at its four corners. This facilitates subsequent maintenance, allowing personnel to access the isolation layer 1 for pipeline repairs using aerial work platforms or similar equipment. The pre-reserved holes 5 are square openings, 1.5-2m wide and 2-3m long. There is a 200-500mm distance between the pre-reserved holes 5 and the surrounding inverted beams 3. The dimensions of the pre-reserved holes 5 and the distance between them and the surrounding inverted beams 3 are adjusted according to the column span. The pre-reserved holes 5 are sealed with gypsum board, leaving a 10mm gap at the edges to facilitate future maintenance and maintain the aesthetic appearance of the seismic isolation base slab 2.

[0055] Pre-reserved hole 6 on the beam is a pre-reserved opening on the inverted beam. The specific location of pre-reserved hole 6 on the beam is reserved in conjunction with the pipe network layout. Pre-reserved hole 6 on the beam is mainly used for air conditioning condensate pipes and fire sprinkler pipes. Pre-reserved hole 6 on the beam uses a steel sleeve for reservation and reinforcement. The size of the reserved hole is reserved in conjunction with the pipes that need to pass through.

[0056] The inverted beam 3 is positioned where high clearance requirements exist for the first floor. The pre-drilled holes 6 on the beam address the installation height issues for air conditioning condenser pipes and fire sprinkler pipes.

[0057] The pipework layout method is as follows: Due to the limited space in the vibration isolation layer 1, and the need to arrange all the electromechanical pipelines 7 on the first floor within the vibration isolation layer 1, the installation and operation space for pipelines in the vibration isolation layer 1 is small, and the problem of subsequent maintenance difficulties needs to be solved. Therefore, after the first row of pipelines is installed, pressure testing should be carried out in accordance with the specifications to ensure that there are no leaks before arranging the pipeline insulation. After the insulation is completed, the second row, the third row of pipelines will be constructed layer by layer. The pipework layout method is to avoid the inability to inspect and maintain the vibration isolation pipework layer later. The electromechanical pipelines 7 are comprehensively arranged in advance, and the pipeline positions and elevations are reasonably arranged and optimized to ensure that the pipelines of various disciplines are reasonably arranged within the effective space, so as to ensure the ceiling height and the space for inspection and maintenance of equipment. Holes 5 are reserved in the slab for equipment maintenance.

[0058] This invention utilizes pre-drilled holes 6 on the inverted beam 3 to allow the air conditioning condensate pipe and fire main pipe to be arranged within the inverted beam, avoiding the pipes from occupying the limited space of the vibration isolation layer and preventing the possibility of these pipes colliding with other pipes within the vibration isolation layer. The pre-drilled holes 6 on the beam also meet the requirements for subsequent maintenance of the pipe network within the vibration isolation layer 1. By using the pre-drilled holes 5 on the slab, pre-drilled holes 6 on the beam, and the arrangement of electromechanical pipelines 7, the height of the vibration isolation layer 1 is reduced while the height of the first floor is increased, resulting in a better building experience, all while maintaining the overall building height. Through a reasonable arrangement of the pipe network, collisions with the electromechanical pipelines 7 are avoided, saving space in the vibration isolation layer 1 and ensuring the requirements for on-site construction and subsequent maintenance are met.

[0059] This invention avoids the pipe occupying the limited space of the vibration isolation layer 1 and prevents the pipe from colliding with other pipes in the vibration isolation layer 1. The pre-reserved hole 5 on the slab meets the requirements for subsequent maintenance of the pipe network in the vibration isolation layer 1. It should be noted that the spatial positional relationship of the pre-reserved hole 5 on the slab, the pre-reserved hole 6 on the beam, and the pipe network arrangement method in this invention can be adjusted according to actual needs and is not limited to the positional relationship shown in the figure.

[0060] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
