Description

Technical Field

[0001] This application relates to the field of building technology, and in particular to a support structure and load-bearing system. Background Technology

[0002] In existing architectural design and construction practices, the waterproofing structure of equipment foundations and roofs usually adopts the integral cast-in-place mode. During the structural construction stage, the equipment foundation support structure (reinforced concrete piers or steel structure embedded parts) and the roof structure layer are poured simultaneously, and all waterproofing processes such as slope finding, heat preservation, waterproof membrane / coating and protective layer are completed in one go. After the equipment arrives, it is directly hoisted onto the pre-set foundation and fixed by pre-embedded anchor plates or chemical anchors.

[0003] However, the foundation dimensions, elevation, and load rating of a single pour often cannot match the requirements of the new equipment after the equipment is replaced. If the foundation position needs to be adjusted or the size needs to be enlarged, the original reinforced concrete and multi-layer waterproof structure must be removed. This not only results in a long construction period and a lot of noise and dust, but also easily causes the roof to leak. Repeated demolition and modification lead to the roof being repeatedly opened and closed, generating a large amount of construction waste. In addition, temporary rain protection measures need to be set up, increasing operation and maintenance costs and downtime risks. Utility Model Content

[0004] This application discloses a support structure and load-bearing system that enables flexible adjustment of the equipment foundation position, size and load as needed, avoiding the problems of leakage risks, long construction period and high operation and maintenance costs caused by the need to remove concrete and damage the existing waterproof layer when constructing a foundation in the traditional way.

[0005] To achieve the above objectives, a first aspect of this application discloses a support structure for equipment support on a building roof. The building roof includes a building surface layer, a first waterproof layer, and a structural layer arranged sequentially from top to bottom. The structural layer includes structural beams. The building roof also has mounting holes corresponding to the structural beams, and the mounting holes penetrate vertically through the building surface layer and the first waterproof layer. The support structure includes:

[0006] A connecting plate is disposed in the mounting hole, the lower surface of the connecting plate is in contact with the structural layer, the upper surface of the connecting plate is flush with the upper surface of the first waterproof layer, the sidewall of the connecting plate is in contact with the first waterproof layer, and the connecting plate is configured to be connected to the structural layer by fasteners.

[0007] A support column is disposed on the upper surface of the connecting plate, and the support column extends along the vertical direction;

[0008] A support plate is disposed on the upper surface of the support column, and the support plate is used to support the equipment;

[0009] A waterproof barrier is provided on the outside of the first waterproof layer and around the periphery of the support column. The waterproof barrier is connected to both the support column and the connecting plate. The waterproof barrier is used to seal the gap between the connecting plate and the first waterproof layer.

[0010] As an optional implementation, the waterproof barrier includes: an insulation layer, which is disposed in contact with the outer peripheral surface of the support column and is connected to both the connecting plate and the first waterproof layer; and a second waterproof layer, which includes a first waterproof area, a second waterproof area, and a third waterproof area that are connected to each other, wherein the first waterproof area is attached to the outer side of the outer peripheral surface of the support column, the second waterproof area is attached to the outer side of the insulation layer, and the third waterproof area is attached to the outer side of the upper surface of the first waterproof layer.

[0011] As an optional implementation, the outer surface of the insulation layer is inclined, and the top end of the outer surface of the insulation layer is closer to the support column than the bottom end of the outer surface of the insulation layer.

[0012] As an optional implementation, the angle between the inclined plane and the horizontal direction is 40° to 50°.

[0013] As an optional implementation, the first waterproof area is provided with a connection hole, and the support structure further includes: a connector, which is disposed in the connection hole and passes through the support column, and is configured to press the second waterproof layer against the outer peripheral surface of the support column; and a first seal, which is disposed in the connection hole and is configured to seal the gap between the connector and the connection hole.

[0014] As an optional implementation, the support structure further includes a second seal, the second seal comprising an adhesive portion and a sealing portion, one end of the adhesive portion and one end of the sealing portion being connected to each other, the adhesive portion being in contact with the outer peripheral surface of the support column, and the sealing portion being in contact with the upper surface of the first waterproof area, the second seal being configured to seal the gap between the first waterproof area and the support column.

[0015] As an optional implementation, the inner circumferential surface of the mounting hole is fitted to the outer surface of the second waterproof area.

[0016] As an optional implementation, the support structure further includes a protective layer that covers the building surface layer and the second waterproof layer, and the protective layer covers the outer surface of the support column that is not attached to the second waterproof layer, and the protective layer extends to the lower surface of the load-bearing plate.

[0017] As an optional implementation, the support column has an installation space inside, the installation space extends through the support column in the vertical direction, the fastener is located in the installation space, and the bearing plate covers the upper opening of the installation space.

The load-bearing system includes: a support structure as described in the first aspect of this application; and a load-bearing structure disposed on a support plate of the support structure, the load-bearing structure being used to support the equipment.

[0019] Compared with the prior art, the beneficial effects of this application are:

[0020] The support structure provided in this application combines equipment support with roof waterproofing, meeting the stable support requirements of building roof equipment. It minimizes damage to the first waterproof layer during the installation of the connecting plate, requiring only partial removal of the first waterproof layer to provide space for the connecting plate installation. This avoids the damage to roof waterproofing and the resulting leakage problems caused by traditional support structures, reducing roof maintenance costs and repair risks. The support structure can adapt to the requirements of different equipment by adjusting components such as support columns and load-bearing plates, improving its flexibility and versatility, and making it suitable for various building roof equipment installation and replacement scenarios.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In this application, the terms "upper," "lower," "top," "bottom," "inner," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0031] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0032] Furthermore, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0033] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0034] In existing architectural design and construction practices, architects, based on preliminary equipment lists and process specifications, complete a full set of detailed structural drawings for the roof structure slabs, slope-forming layer, insulation layer, waterproofing layer, and protective layer, and pre-reserve reinforced concrete piers or embedded steel plate anchors at corresponding locations. During the construction phase, when the reinforcing steel is tied in the roof structure layer, the equipment foundation is poured together with the roof concrete. After the equipment arrives, it is directly hoisted onto the pre-designated foundation and fixed using pre-embedded anchor plates or chemical anchors.

[0035] However, while existing methods facilitate simultaneous delivery in the early stages, the fixed foundation dimensions, elevation, and load-bearing capacity during the design phase make it difficult to adapt to changes in equipment models, weights, and anchor placement later on. This means that if equipment models or loads change, the only solution is to remove the hardened concrete from the roof, cut the reinforcing bars, damage multiple layers of waterproofing, re-install reinforcement or use chemical anchors to secure the new foundation, and then repair the waterproofing a second time. This creates potential leakage risks and significantly extends the construction period. Cold joints exist at the interface between the old and new concrete, and post-installed anchors are prone to fatigue failure under high-frequency vibration and large eccentric loads. Furthermore, the joints of the subsequently applied roofing membrane or coating are highly susceptible to cracking and leakage under temperature cycles and long-term dynamic loads. Repeated demolition and alterations generate substantial construction waste, temporary rain protection measures, and downtime losses, increasing operation and maintenance costs.

[0036] Based on this, the present application discloses a support structure and load-bearing system, which realizes flexible adjustment of the equipment foundation position, size and load as needed, avoiding the problems of leakage hazards, long construction period and high operation and maintenance costs caused by the need to remove concrete and damage the existing waterproof layer when building a foundation in the traditional way.

[0037] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0038] Please see Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of the building roof 200 provided in an embodiment of this application; Figure 2This is a schematic diagram of the support structure 100 provided in an embodiment of this application. This application discloses a support structure 100 for equipment support on a building roof 200. The building roof 200 includes a building surface layer 201, a first waterproof layer 202, and a structural layer 203 arranged sequentially from top to bottom. The structural layer 203 includes structural beams 2031. The building roof 200 also has mounting holes, which are corresponding to the structural beams 2031 and penetrate vertically through the building surface layer 201 and the first waterproof layer 202. The support structure 100 includes a connecting plate 1, which is disposed in the mounting holes. The lower surface of the connecting plate 1 is in contact with the structural layer 203, and the upper surface of the connecting plate 1 is in contact with the first waterproof layer 202. The upper surface of the waterproof layer 202 is flush with the first waterproof layer 202. The sidewall of the connecting plate 1 is attached to the first waterproof layer 202. The connecting plate 1 is configured to be connected to the structural layer 203 by fasteners 11. The support column 2 is set on the upper surface of the connecting plate 1 and extends vertically. The bearing plate 3 is set on the upper surface of the support column 2 and is used to support the equipment. The waterproof barrier 4 is set on the outside of the first waterproof layer 202 and surrounds the periphery of the support column 2. The waterproof barrier 4 is connected to both the support column 2 and the connecting plate 1 and is used to seal the gap between the connecting plate 1 and the first waterproof layer 202.

[0039] The building roof 200 is composed of, from top to bottom, a building surface layer 201, a first waterproof layer 202, and a structural layer 203, with the structural layer 203 containing structural beams 2031. The building roof 200 also has mounting holes corresponding to the structural beams 2031, which vertically penetrate the building surface layer 201 and the first waterproof layer 202. This provides a channel and connection point for the subsequent installation of the support structure 100, while ensuring that the support structure 100 can be directly connected to the main structure of the building, i.e., the structural beams 2031, achieving stable support. This allows the support structure 100 to transfer equipment loads to the main building structure, ensuring the stability and reliability of the equipment support.

[0040] The connecting plate 1 is set in the mounting hole. The lower surface of the connecting plate 1 is attached to the structural layer 203 and connected to the structural layer 203 by fasteners 11. This ensures a stable connection between the support structure 100 and the structural layer 203 of the building roof 200, providing a connection foundation for the entire support system, thereby transferring the equipment load to the structural beam 2031 and ensuring the stability and safety of the equipment installed on the roof.

[0041] Since the mounting hole penetrates vertically through the building surface layer 201 and the first waterproof layer 202, and the upper surface of the connecting plate 1 is flush with the upper surface of the first waterproof layer 202, and the sidewall is attached to the first waterproof layer 202, it is possible to partially remove the first waterproof layer 202 to provide space for the installation of the connecting plate 1 without damaging the integrity of the first waterproof layer 202. At the same time, it can ensure the connection between the connecting plate 1 and the first waterproof layer 202 after installation, and maintain the integrity of the roof waterproofing system.

[0042] The support column 2 is installed on the upper surface of the connecting plate 1 and extends vertically, providing vertical support for the equipment and capable of bearing its weight. The support column 2 transfers and distributes the concentrated load of the equipment to the connecting plate 1 and the structural beam 2031, avoiding localized damage to the roof structure caused by excessive concentration of equipment load, helping to extend the service life of the roof structure and enhance its load-bearing capacity and durability.

[0043] Optionally, the support column 2 can be designed and adjusted according to the height requirements of different equipment to meet the installation and use needs of various equipment, thereby improving the versatility and flexibility of the support structure 100.

[0044] The bearing plate 3 is set on the upper surface of the support column 2, providing a stable installation platform for the equipment, ensuring that the equipment can operate on a stable foundation, which is conducive to the normal operation and accuracy maintenance of the equipment, and reduces the risk of vibration and failure caused by unstable foundation.

[0045] Optionally, the size and shape of the support plate 3 can be designed according to the specific requirements of the equipment to meet the installation needs of equipment of different sizes and shapes, improve the applicability and practicality of the support structure 100, and enable the support structure 100 to better adapt to the support requirements of various building roof equipment.

[0046] The waterproof barrier 4 is installed on the outside of the first waterproof layer 202 and surrounds the periphery of the support column 2. It is connected to both the support column 2 and the connecting plate 1, enhancing the waterproof performance between the support structure 100 and the roof waterproof layer. The waterproof barrier 4 protects the connection between the connecting plate 1 and the support column 2, preventing the connection from being directly exposed to the external environment and subjected to erosion from natural factors such as rainwater and ultraviolet rays, thus extending the service life of the connection and ensuring the long-term stability and safety of the support structure 100.

[0047] Meanwhile, the waterproof barrier 4 can prevent water from seeping into the roof from the gap between the support column 2 and the connecting plate 1, thus compensating for any potential weaknesses in the waterproofing and improving the reliability and stability of the roof waterproofing system.

[0048] Thus, the support structure 100 provided in this embodiment combines equipment support with roof waterproofing, meeting the stable support requirements of building roof equipment. This minimizes damage to the first waterproof layer 202 during the installation of the connecting plate 1, requiring only partial removal of the first waterproof layer 202 to provide space for the installation of the connecting plate 1. This avoids the damage to roof waterproofing and the resulting leakage problems caused by traditional support structures 100, reducing roof maintenance costs and repair risks. The support structure 100 can adapt to the requirements of different equipment by adjusting components such as the support column 2 and the load-bearing plate 3, improving its flexibility and versatility, and making it suitable for various building roof equipment installation and replacement scenarios.

[0049] Please see Figure 2 and Figure 3 , Figure 3 for Figure 2 In the enlarged view at point A, in some embodiments, the waterproof barrier 4 includes: an insulation layer 41, which is attached to the outer peripheral surface of the support column 2 and is connected to both the connecting plate 1 and the first waterproof layer 202; and a second waterproof layer 42, which includes a first waterproof area 421, a second waterproof area 422, and a third waterproof area 423 that are connected to each other. The first waterproof area 421 is attached to the outer side of the outer peripheral surface of the support column 2, the second waterproof area 422 is attached to the outer side of the insulation layer 41, and the third waterproof area 423 is attached to the outer side of the upper surface of the first waterproof layer 202.

[0050] The insulation layer adheres to the outer perimeter of the support column 2 and connects to the connecting plate 1 and the first waterproof layer 202. In cases of significant indoor-outdoor temperature differences, without insulation, the surface temperature of the support column 2 may fall below its dew point, causing water vapor in the air to condense on the column surface. The insulation layer 41 reduces condensation, preventing roof leaks, equipment damage, and structural corrosion caused by condensation buildup, thus ensuring stable equipment operation and the safety of the roof structure.

[0051] The second waterproof layer 42 is composed of three interconnected waterproof zones: a first waterproof zone 421, a second waterproof zone 422, and a third waterproof zone 423, forming a complete waterproof barrier. The first waterproof zone 421 is attached to the outer periphery of the supporting column 2, forming the first waterproof barrier on the outside of the insulation layer 41, preventing water from seeping in through the gap between the supporting column 2 and the insulation layer 41. The second waterproof zone 422 is attached to the outside of the insulation layer 41, not only protecting the insulation layer 41 from water erosion but also working synergistically with the insulation layer 41 to further enhance the waterproof effect. The third waterproof zone 423 is attached to the outer surface of the upper surface of the first waterproof layer 202, working in conjunction with the original first waterproof layer 202 to form double waterproof protection, improving the reliability and durability of the roof waterproofing.

[0052] The second waterproof layer 42 avoids weak points in the roof waterproofing caused by the installation of the support structure 100, reduces the risk of roof leakage, reduces the later maintenance costs and frequency, and provides a more stable and reliable waterproofing solution for the building roof equipment support.

[0053] Please see Figure 2 In some embodiments, the outer surface of the insulation layer 41 is a slope, and the top of the outer surface of the insulation layer 41 is closer to the support column 2 than the bottom of the outer surface of the insulation layer 41.

[0054] In preventing condensation, the sloping structure helps guide the water flow. When water vapor in the air condenses on the surface of the support structure 100, the sloping surface guides the condensate away from the support column 2, thus preventing condensate from accumulating around the support column 2. This reduces the risk of condensate seeping into the connection between the support column 2 and the structural layer 203, and also reduces the risk of metal component corrosion and electrical short circuits caused by condensate accumulation, ensuring the normal operation and service life of the equipment.

[0055] In terms of enhancing waterproofing performance, the slope of the insulation layer 41, together with the surrounding waterproofing layer, forms a guiding waterproofing system. When rainwater or other water sources come into contact with the supporting structure 100, the slope can effectively guide the water to the drainage slope direction of the waterproofing layer, accelerating the excretion of water and reducing the time that water stays around the supporting structure 100.

[0056] Meanwhile, the sloping structure also prevents water from forming a back slope around the support column 2, avoiding the risk of leakage due to water accumulation, and further improving the reliability and durability of the entire roof waterproofing system. In addition, the sloping surface helps to optimize the streamline of the support structure 100, reducing local pressure differences that may be caused by water flow impact or wind pressure changes, making the support structure 100 more stable and safer in long-term use.

[0057] In some embodiments, the angle between the inclined plane and the horizontal direction is 40° to 50°. Preferably, the angle between the inclined plane and the horizontal direction can be 45°.

[0058] An angle of 40°–45° between the inclined plane and the horizontal direction optimizes the guidance of condensate. Within this angle range, condensate can flow down the inclined plane more quickly and smoothly. This is because the inclination of the 40° to 50° slope is sufficient for the water flow to overcome surface tension and any possible minor unevenness, thus preventing the accumulation and retention of water droplets. The water can quickly slide down the inclined plane, reducing the risk of seepage caused by water droplet retention and also reducing the possibility of condensate erosion at the joints.

[0059] Furthermore, from a structural stability perspective, the 40° to 50° slope angle guides water flow while also considering the rationality of structural stress. This angle ensures drainage efficiency while avoiding stress concentration issues caused by excessive slope. This allows the insulation layer 41 and the supporting structure 100 to remain stable and intact even under long-term water flow impact and wind loads, extending the service life of the entire supporting structure 100.

[0060] Please see Figure 4 , Figure 4 for Figure 2 A partial enlarged view at point B. In some embodiments, the first waterproof area 421 is provided with a connection hole, and the support structure 100 further includes: a connector 5, which is disposed in the connection hole and passes through the support column 2, and is configured to press the second waterproof layer 42 against the outer peripheral surface of the support column 2; and a first seal, which is disposed in the connection hole and is configured to seal the gap between the connector 5 and the connection hole.

[0061] The connection holes in the first waterproof zone 421, in conjunction with the connector 5, allow the second waterproof layer 42 to be pressed tightly against the outer circumferential surface of the support column 2. This ensures a tight bond between the second waterproof layer 42 and the support column 2. The passage and tightening of the connector 5 prevents moisture from seeping in through the gap between the second waterproof layer 42 and the support column 2. This improves the fit of the second waterproof layer 42 and enhances the overall integrity of the support structure 100, making it more stable and reliable when supporting equipment.

[0062] Meanwhile, the first seal further enhances the sealing performance of the connection. Located within the connection hole, the first seal seals the gap between the connector 5 and the connection hole. It prevents moisture from entering the support structure 100 through the connection hole, ensuring the dryness and safety of the equipment support area. Furthermore, the first seal prevents dust and other impurities in the air from entering the connection, thus protecting the connector 5 from corrosion and wear, and extending the service life of the support structure 100.

[0063] Please see Figure 4 In some embodiments, the support structure 100 further includes a second seal 6, which includes an adhesive portion 61 and a sealing portion 62. One end of the adhesive portion 61 and one end of the sealing portion 62 are connected to each other. The adhesive portion 61 is attached to the outer peripheral surface of the support column 2, and the sealing portion 62 is attached to the upper surface of the first waterproof area 421. The second seal 6 is configured to seal the gap between the first waterproof area 421 and the support column 2.

[0064] The fitting part 61 fits tightly against the outer peripheral surface of the support column 2, while the sealing part 62 fits against the upper surface of the first waterproof area 421, forming a double sealing effect. The second seal 6 not only seals the tiny gap between the first waterproof area 421 and the support column 2, but also further blocks potential paths for water infiltration. The second seal 6 and the first seal work together to form a comprehensive sealing system, ensuring that the support structure 100 can maintain good waterproof performance under complex climatic conditions.

[0065] In addition, the presence of the second seal 6 also ensures the long-term stable operation of the support structure 100, preventing damage to the support structure 100 and increased maintenance costs caused by moisture infiltration, while extending the service life of the entire support structure 100 and reducing maintenance needs.

[0066] Optionally, the second seal 6 can be an angle steel. The strength and rigidity of the angle steel enable it to effectively resist external physical impacts and environmental erosion, while ensuring the durability of the sealing effect. The angle steel has good corrosion resistance, which can maintain the sealing function for a long time, reducing the frequency of maintenance and replacement, thereby extending the service life of the support structure 100.

[0067] Please see Figure 2 In some embodiments, the inner circumferential surface of the mounting hole is in contact with the outer surface of the second waterproof area 422. Regarding waterproofing performance, the contact between the inner circumferential surface of the mounting hole and the outer surface of the second waterproof area 422 enhances the seal between them, preventing moisture from seeping into the roof interior through gaps between the mounting hole and the second waterproof area 422, thus improving the waterproofing performance of the support structure 100.

[0068] In terms of structural stability, the fit between the inner circumferential surface of the mounting hole and the outer surface of the second waterproof zone 422 makes the connection between the support structure 100 and the building roof 200 tighter and more stable. This helps to improve the load-bearing capacity of the support structure 100 and enhances its stability under equipment loads, wind loads, and seismic forces. Furthermore, the fit between the inner circumferential surface of the mounting hole and the outer surface of the second waterproof zone 422 reduces stress concentration caused by temperature changes, structural deformation, and other factors, extending the service life of the support structure 100 and reducing maintenance costs.

[0069] Please see Figure 2 In some embodiments, the support structure 100 further includes a protective layer 7, which covers the building surface layer 201 and the second waterproof layer 42, and covers the outer surface of the support column 2 that is not attached to the second waterproof layer 42, and extends to the lower surface of the bearing plate 3.

[0070] The protective layer 7 covers the building surface layer 201 and the second waterproof layer 42, and extends to the lower surface of the supporting plate 3. It prevents direct impact and abrasion of external objects on the second waterproof layer 42, the outer surface of the supporting column 2, and the building surface layer 201, providing physical protection for the entire supporting structure 100. For example, in severe weather conditions such as hail or strong winds, or in the event of accidental collisions during equipment maintenance, the protective layer 7 can act as a buffer and protector, reducing the risk of structural damage.

[0071] The protective layer 7 covers the outer surface of the support column 2 that is not adhered to the second waterproof layer 42, further enhancing the corrosion resistance and weather resistance of the support column 2. This extends the service life of the support column 2 and also ensures the stability and safety of the support structure 100 during long-term use.

[0072] Please see Figure 2 In some embodiments, an installation space 21 is formed inside the support column 2, the installation space 21 extends vertically through the support column 2, the fastener 11 is located inside the installation space 21, and the bearing plate 3 covers the upper opening of the installation space 21.

[0073] This layout not only avoids potential safety hazards caused by exposed fasteners 11, but also effectively improves the overall integrity and aesthetics of the support structure 100. Meanwhile, the bearing plate 3 covers the upper opening of the installation space 21, serving a dual purpose of sealing and protection. This covering method of the bearing plate 3 prevents foreign objects or moisture from entering through the opening at the top of the support column 2, protecting the internal fasteners 11 and other components from external environmental corrosion, and also ensures the stability and reliability of the support structure 100 during long-term use.

[0074] In addition, this design helps to optimize the stress performance of the support structure 100, so that the weight of the equipment can be more evenly distributed on the entire support structure 100, thereby improving the load-bearing capacity and durability of the support structure 100.

[0075] Please see Figure 5 , Figure 5 This is a structural schematic diagram of the support system 300 provided in the embodiments of this application. A second aspect of this application provides a support system 300 for supporting equipment on a building roof 200. The support system 300 includes: a support structure 100 as described in the first aspect of this application; and a support structure 301 disposed on the support plate 3 of the support structure 100, which is used to support equipment.

[0076] The support plate 3 of the support structure 100 provides a solid foundation for the support structure 301. The support structure 301 itself is used to meet the load-bearing requirements of different equipment, ensuring the stable operation and safety of the equipment.

[0077] It should be noted that the support structure 100 in the load-bearing system 300 has the same structure as any of the support structures 100 in the above embodiments and can bring the same or similar beneficial effects.
