Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of civil engineering, in particular to a suspension structure system based on vertical cable. BACKGROUND

[0002] With the continuous expansion of the scale of urban development, land resources are becoming increasingly scarce, and industrial land supply is in short supply. In the face of the above situation, more and more cities have changed the traditional method of expanding industrial facilities in the plane space and implemented the mode of expanding industrial facilities in the vertical space, so as to realize the purpose of saving industrial land and maximizing the concentration of industrial facilities, that is, "industrial up".

[0003] When the industry goes up, the production, office, research and development, design and other needs of the enterprise need to be carried out in the same building, and the building structure needs to create multiple production large spaces, multiple office spaces, vertical transportation and horizontal transportation channels and other functional areas in the vertical space.

[0004] In the Chinese patent with publication number CN 106996153B, an overall tensioning suspension system is disclosed, in which the suspension structure is suspended in the main structure, the suspension structure includes a plurality of floor slabs arranged vertically in layers, the topmost floor slab is fixed to the top of the main structure, the bottommost floor slab is anchored and supported on the ground by a stable cable rod, and each adjacent two floor slabs in the middle are anchored and supported by a cable rod. This kind of suspension structure can reduce production vibration while providing different functional spaces for industrial up projects.

[0005] However, this system needs special design for the compatibility of efficient vertical and horizontal transportation channels. At the same time, in the face of the demand of industrial up project for large-span large space at the bottom of the building and production and research space at the top, the compatibility of this system is insufficient.

[0006] Therefore, the existing tensioning suspension system has the technical problem of low applicability due to the above technical defects, and thus it is necessary to develop a high-applicability suspension system to meet the functional requirements of industrial up projects and effectively promote the rapid development of this new type of industrial mode. SUMMARY

[0007] In view of the technical problem of low applicability of the existing tensioning suspension system, the purpose of the present application is to provide a suspension structure system based on vertical cable, which can create multiple production large spaces, multiple office spaces, vertical transportation and horizontal transportation channels and other functional areas in the vertical space of the building structure, thereby improving the applicability of the suspension structure system and overcoming the problems existing in the prior art to some extent.

[0008] To achieve the above objectives, the present invention provides a suspension structure system based on vertical tension, comprising a vertical main structure, a horizontal rigid floor suspension device, and a vertical integral tension cable device. The horizontal rigid floor suspension device includes several horizontal rigid floor suspension layers of varying lengths, which are symmetrically arranged along the middle of the vertical main structure, decreasing in length towards both ends. The two end faces of the vertical integral tension cable device are respectively fitted to the two end faces of the vertical main structure, and the two sides of the vertical integral tension cable device are respectively arranged along the two end ports of the several horizontal rigid floor suspension layers and connected to each horizontal rigid floor suspension layer. By applying a preload, a constraint force relative to the vertical main structure can be generated on each horizontal rigid floor suspension layer.

[0009] Furthermore, the plurality of horizontal rigid floor suspension layers respectively include a first horizontal rigid floor suspension layer, a middle horizontal rigid floor suspension layer and a top horizontal rigid floor suspension layer. The first horizontal rigid floor suspension layer, the middle horizontal rigid floor suspension layer and the top horizontal rigid floor suspension layer are distributed sequentially upward along the vertical main structure to form floors of different heights.

[0010] Furthermore, the vertical main structure includes, from the outside to the inside, a load-bearing structure, a vertical spiral track, and an elevator shaft; the vertical spiral track is located in the middle of the elevator shaft and is integrally set between the load-bearing structures, and the vertical spiral track spirals upward along the height to form a vertical channel of the structure.

[0011] Furthermore, the first horizontal rigid floor suspension layer and the middle horizontal rigid floor suspension layer are connected by a vertical spiral channel or elevator shaft, and the top horizontal rigid floor suspension layer is connected by an elevator shaft.

[0012] Furthermore, a first prefabricated suspension space is provided at the bottom of the horizontal rigid floor suspension layer.

[0013] Furthermore, the first prefabricated suspended space is suspended to the bottom of the horizontal rigid floor suspension device by means of a suspension connection and vibration damping device.

[0014] Furthermore, the suspension connection and vibration damping device includes several sets of suspension connection and vibration damping components, which are symmetrically arranged at the top of the first prefabricated suspension space; each set of suspension connection and vibration damping components includes a fixing cable and an energy dissipation device; the two ends of the fixing cable are respectively connected to the first prefabricated suspension space and the horizontal rigid floor suspension device; the vibration damping device is provided on the fixing cable and its two ends are respectively connected to the first prefabricated suspension space and the horizontal rigid floor suspension device.

[0015] Furthermore, a second prefabricated multi-story space is provided above the top horizontal rigid floor suspension layer. The second prefabricated multi-story space is assembled from a structural frame and internal columns.

[0016] Furthermore, the second prefabricated multi-story space is connected to the top horizontal rigid floor suspension layer by setting up a swing self-resetting system.

[0017] Furthermore, the swing self-resetting system includes pre-tensioned cables and an energy dissipation device at the bottom of the column;

[0018] The pre-tensioned cable passes through the inner column of the second prefabricated multi-story space, connecting the second prefabricated multi-story space to the top horizontal rigid floor suspension layer;

[0019] The energy-consuming device is installed at the bottom of the second prefabricated multi-layer space structure frame and is attached to the top horizontal rigid floor suspension layer.

[0020] The energy-consuming device deforms and consumes energy when the second prefabricated multi-layer space vibrates and shakes. After the vibration ends, the second prefabricated multi-layer space returns to its original position under its own weight.

[0021] The suspension structure system based on vertical tension provided by this invention can meet the needs of industrial buildings for multi-story production spaces, multi-story office spaces, vertical transportation and horizontal transportation channels through reasonable spatial arrangement, which greatly improves the applicability of the suspension structure.

[0022] Secondly, the vertical main structure, the horizontal rigid floor suspension layer, and the vertical integral tension cable of this invention form a tensioned cable structure along the height of the structure, which makes the force transmission path simple and clear, the structure is subjected to reasonable stress, and improves the reliability of the suspension structure.

[0023] Meanwhile, this invention makes full use of various damping devices or systems. For example, the main structure and the suspension body can interact with each other, which can play a role similar to a tuned mass damper, and can keep the displacement of the top of the main structure within a very small range. The swaying self-resetting between the multi-level office space at the top and the top horizontal rigid floor can fully reduce the whiplash effect of the structure. Attached Figure Description

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0036] See Figure 1 The present invention provides a suspension structure system based on vertical tension cable, including a vertical main structure 1, a horizontal rigid floor suspension device 2, a vertical integral tension cable device 3, a prefabricated suspended office space 4, and a multi-level office space on the top 6.

[0037] See Figure 2 The horizontal rigid floor suspension device 2 includes several horizontal rigid floor suspension layers. The lengths of the several horizontal rigid floor suspension layers are not consistent. The several horizontal rigid floor suspension layers are symmetrically arranged along the middle of the vertical main structure 1, with the length decreasing sequentially from both ends.

[0038] This plan does not limit the structural options for those with inconsistent lengths of the suspended layers forming a horizontal rigid floor. For example: see [link to example]. Figure 2 During the initial construction, horizontal rigid floor suspension layers of different lengths can be prefabricated and symmetrically arranged along the middle of the vertical main structure 1 towards both ends.

[0039] Secondly, see Figure 3 Alternatively, the horizontal rigid floor suspension layer of each floor can be prefabricated to be of uniform length, and reinforcement components 24 can be added to both ends of the horizontal rigid floor suspension layer of each floor.

[0040] Specifically, the longest reinforcing components 24 are installed at both ends of the horizontal rigid floor suspension layer located in the middle of the vertical main structure 1, so that the horizontal rigid floor suspension layer located in the middle of the vertical main structure 1 is the longest floor layer.

[0041] The horizontal rigid floor suspension layers distributed on both sides of the middle floor are provided with reinforcement components 24 of gradually decreasing length along the vertical main structure 1, so that several horizontal rigid floor suspension layers are symmetrically arranged with their lengths decreasing from the middle to both ends along the vertical main structure 1.

[0042] The above two structural schemes do not limit the length of the suspended layer of the horizontal rigid floor. The specific structural scheme can be selected according to the actual situation.

[0043] Several horizontal rigid floor suspension layers can be divided into a first horizontal rigid floor suspension layer 21, a middle horizontal rigid floor suspension layer 22, and a top horizontal rigid floor suspension layer 23.

[0044] Among them, the first horizontal rigid floor suspension layer 21, the middle horizontal rigid floor suspension layer 22 and the top horizontal rigid floor suspension layer 23 are distributed upward along the vertical main structure 1 in sequence, and the first horizontal rigid floor suspension layer 21, the middle horizontal rigid floor suspension layer 22 and the top horizontal rigid floor suspension layer 23 are rigidly connected to the vertical main structure to form floors of different heights.

[0045] Furthermore, the vertical main structure 1 is the main vertical force transmission component, see [reference needed]. Figure 2 From the outside to the inside, it includes a load-bearing structure 11, a vertical spiral channel 12, and an elevator shaft 13.

[0046] The load-bearing structure 11 is the main load-bearing component, which has sufficient rigidity to resist all horizontal and vertical loads. It is located in the middle of the overall suspension structure system and is the vertical force transmission component of the overall suspension system. Its interior is a hollow structure, which is used to set up the vertical spiral track 12 and the elevator shaft 13. The vertical spiral track 12 and the elevator shaft 13 are distributed inside the load-bearing structure. The vertical spiral track 12 and the elevator shaft 13 are used to provide vertical transportation functions for goods and personnel, respectively.

[0047] Furthermore, the vertical spiral channel 12 is located in the middle of the elevator shaft 13 and is integrally set between the load-bearing structures 11. It spirals upward along the height, allowing transport vehicles to travel vertically and providing vertical transportation function for the structure.

[0048] Since the vertical spiral hoistway 12 is used to transport goods, there is no need to transport goods at the top horizontal rigid floor suspension layer 23 and above. Therefore, the vertical spiral hoistway 12 can only reach the first horizontal rigid floor suspension layer 21 and the middle horizontal rigid floor suspension layer 22. The elevator shaft 13 can reach the first horizontal rigid floor suspension layer 21, the middle horizontal rigid floor suspension layer 22 and the top horizontal rigid floor suspension layer 23.

[0049] The vertical spiral walkway 12 transport equipment can be used to transport the equipment from the ground to the next floor. It can be connected with the first horizontal rigid floor suspension layer 21 or the middle horizontal rigid floor suspension layer 22. The first horizontal rigid floor suspension layer 21 or the middle horizontal rigid floor suspension layer 22 provides a horizontal passage for the structure.

[0050] Specifically, as the vertical spiral channel 12 ascends along the height, it can move within the first horizontal rigid floor suspension layer 21 and the middle horizontal rigid floor suspension layer 22 after reaching each floor, thus realizing the transportation of goods in the horizontal passageway within the large space of different floors.

[0051] The structure and working principle of the vertical spiral channel 12 and the elevator shaft 13 are well known to those skilled in the art, and will not be described in detail here.

[0052] It should be noted that this design does not limit the external shape of the main vertical structure. For example, see [link to example]. Figures 4-5 It can be a rectangular structure or a cylindrical structure, depending on the specific circumstances.

[0053] See 1- Figure 5 The vertical integral tensioning cable device 3 is a steel cable 31. The steel cable 31 is connected to the vertical main structure 1 and the horizontal rigid floor suspension layer respectively. The three of them form a tensioned structure along the height of the structure. The application of prestress provides vertical constraint for the horizontal rigid floor suspension device.

[0054] Specifically, the upper and lower ends of the steel cable 31 are tensioned to the upper and lower ends of the vertical main structure 1, respectively, and the left and right ends are set along the ports of each horizontal rigid floor suspension layer and connected to each horizontal rigid floor suspension layer.

[0055] Because the length of each horizontal rigid floor suspension layer is inconsistent, the vertical constraint force of the steel cable 31 will generate several component forces, which can generate a thrust relative to the vertical main structure 1 on each horizontal rigid floor suspension layer, tightening each horizontal rigid floor and presenting an overall spindle shape.

[0056] The number of steel cables 31 is not limited in this scheme. It is preferable to use several cables symmetrically distributed along the vertical main structure 1 and several horizontal rigid floor suspension layers, so as to ensure that the horizontal rigid floor suspension layers can be stably assembled with the vertical main structure 1.

[0057] The vertical main structure 1, the horizontal rigid floor suspension device, and the vertical overall tension cable device 3 form a tensioned cable structure along the height of the structure, with a simple and clear force transmission path and reasonable structural stress.

[0058] It should be noted that the vertical integral tension cable device 3 is limited by the distribution structure along the outer surface of the structure. The vertical integral tension cable 3 can be evenly arranged according to different structural shapes, and the specific distribution structure can be determined according to the actual situation.

[0059] Furthermore, the upper part of the horizontal rigid floor suspension layer is the production space, in which the prefabricated suspended office space 4 is connected in the factory or on the ground and then suspended to the lower part of the horizontal rigid floor suspension layer through the suspension connection and vibration damping device 5.

[0060] See Figure 6 The suspension connection and vibration damping device 5 is installed on the top of the prefabricated suspended office space 4 and connected to the internal columns of the prefabricated suspended office space 4. The office space is connected to the horizontal rigid floor suspension layer of each floor through the suspension connection and vibration damping device 5 to form the prefabricated suspended office space structure.

[0061] Secondly, the prefabricated suspended office space, extending from the lower level to the upper part of the horizontal rigid floor suspension layer, provides a large production space for the structure, meeting production needs.

[0062] Furthermore, the suspension connection and vibration damping device 5 includes several sets of suspension connection and vibration damping components, which are symmetrically arranged on the top of the prefabricated suspended office space. Each set of suspension connection and vibration damping components includes a fixing cable 51 and an energy dissipation device 52.

[0063] The prefabricated suspended office space 4 has pre-drilled holes 53 in its columns. The fixing cable 51 in the suspension connection and vibration damping device passes through the holes and is connected to the upper horizontal rigid floor suspension layer. The prefabricated suspended office space 4 is suspended by applying pre-tension force.

[0064] The suspension connection and vibration damping device 5 can absorb the vibration of the horizontal rigid floor suspension device 2 caused by production equipment, transportation equipment, etc. while fixing the prefabricated suspended office space 4, thereby ensuring the comfort of the prefabricated suspended office space 4.

[0065] In addition, the suspension connection and vibration damping device 5 and the prefabricated suspended office space 4 are fitted together with the vertical main structure 1 during assembly, and can interact with the vertical main structure 1. They can play a role similar to the tuned mass damper, and can keep the displacement of the top of the main structure 1 within a very small range when it shakes.

[0066] The structural composition of the vibration damping device is not limited here. The specific configuration can be determined according to the actual situation. For example, it can be a vibration damping spring or vibration damping rubber. The vibration damping spring or vibration damping rubber is sleeved on the fixing cable 51, and the two ends are respectively in contact with the prefabricated suspended office space 4 and the horizontal rigid floor suspension device 2 to dampen the horizontal rigid floor suspension device 2, thereby ensuring the comfort of the prefabricated suspended office space 4.

[0067] Furthermore, the top multi-level office space 6 is located above the top horizontal rigid floor suspension layer 23 at the very top of the structure. The structural frame 61 of the top multi-level office space is connected to the top horizontal rigid floor suspension layer 23 using a swing self-resetting system.

[0068] See Figure 7 The swing self-resetting system includes a pre-tensioned cable 62 and an energy dissipation device 63 at the bottom of the column.

[0069] The pre-tensioned cable 62 passes through the inner column of the top multi-level office space 6 and connects the top horizontal rigid floor suspension layer 23 of the top multi-level office space 6.

[0070] The energy-consuming device 63 is installed at the bottom of the structural frame 61 of the multi-story office space and is attached to the top horizontal rigid floor suspension layer 23.

[0071] The vertical constraint between the top multi-level office space 6 and the top horizontal rigid floor suspension layer 23 is only ensured by the pre-tension cable 62 of the swing self-resetting system. At the columns of the top multi-level office space 6 where there is no pre-tension cable 62, the horizontal constraint between it and the top horizontal rigid floor suspension layer 23 is released, allowing the top multi-level office space 6 to swing freely.

[0072] It should be noted that this scheme does not limit the structural method for releasing the horizontal constraint between the pre-tensioned cable 62 and the top horizontal rigid floor suspension layer 23. There are many supports in the field of civil engineering that can achieve this effect. Their specific working structures and working principles are well known to those skilled in the art, so they will not be described in detail here.

[0073] An energy-dissipating device 63 is installed at the bottom of the column. The energy-dissipating device 63 is used to buffer the energy generated by the shaking or vibration of the multi-story office space 6 at the top due to external forces.

[0074] like Figure 8 As shown, under the action of wind load, seismic load and other loads, the columns of the six parts of the multi-story office space at the top detach from the top horizontal rigid floor suspension layer 23, causing the energy dissipation device 63 to deform and reduce vibration.

[0075] Because the center of gravity of the multi-level office space at the top is still within the projected area of ​​the structure while it is shaking, it will not overturn. Therefore, after the shaking ends, it will self-reset under the pre-tension of the pre-tension cable 62 and its own gravity.

[0076] The composition and working principle of the energy-consuming device 63 are well known to those skilled in the art, and will not be described in detail here; at the same time, the structural type of the energy-consuming device is not limited in this solution, and can be determined according to the actual situation.

[0077] The suspension structure based on vertical tension, constructed using the above scheme, can meet the functional needs of industrial multi-story buildings for large multi-level production spaces, multi-level office spaces, and vertical and horizontal transportation channels through reasonable spatial arrangement. This greatly improves the applicability of the suspension structure.

[0078] Secondly, the vertical main structure, the horizontal rigid floor suspension layer, and the vertical integral tension cable of this invention form a tensioned cable structure along the height of the structure, which makes the force transmission path simple and clear, the structure is subjected to reasonable stress, and improves the reliability of this suspension structure.

[0079] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
