Description

Technical Field

[0001] The present application relates to the field of construction engineering, and in particular to a tuned liquid damper structure under a helipad on the top floor of a super high-rise building. Background Art

[0002] Supertall buildings, also known as skyscrapers, are typically used for commercial, office, and residential purposes. Their design and construction must take into account various factors, such as structural strength, wind resistance, earthquake preparedness, fire safety, energy conservation, and environmental protection. In recent years, with the continuous development of technology and the accelerated advancement of urbanization, an increasing number of supertall buildings have emerged, becoming a new highlight of urban development.

[0003] The top floor of a super high-rise building is built with a tuned liquid damper. The tuned liquid damper is mainly composed of a water tank body and multiple paddle columns fixed in the inner cavity of the water tank body. The water tank body is generally made of reinforced concrete materials, and the paddle columns are generally steel structures. The water in the water tank body can cooperate with the structure of the water tank body to achieve the effect of damping and vibration reduction, and can also be used as fire-fighting water.

[0004] A Chinese patent document (publication number: CN114922427A) discloses a TLD slurry column structure and an integrated construction method for firmly connecting it to a main structure. The slurry column structure includes one or more slurry column bodies, and the multiple slurry column bodies are arranged in parallel and spaced apart. The slurry column body is a columnar structural member. An anchoring assembly is integrally provided at both ends of the slurry column body. The anchoring assembly includes an anchor plate and a plurality of anchor bars arranged on the anchor plate. The anchor plate is connected to the end face of the slurry column body, and the anchor bar is arranged on the plate surface of the anchor plate away from the slurry column body. An installation hole is formed on the anchor plate, and an anchor bar is welded and fixed in the installation hole. The anchor bar includes a vertical portion and a straight portion perpendicular to the vertical portion. The straight portion of the anchor bar is used to achieve welding and fixation with the water tank.

[0005] Due to urban traffic congestion and limited parking spaces, helipads are built on the roofs of super high-rise buildings in order to save time and conserve limited urban space. In addition, building helipads on roofs can also provide convenience for certain special industries. For example, when emergency vehicles or police cars such as hospitals and police stations need to respond to emergencies, they can take off or land directly from the roof of the building. Due to the limited space on the roof and the construction of the helipad, the structural size of the water tank body is limited, the water storage capacity is reduced, and the minimum water consumption for fire fighting cannot be met. Summary of the Invention

[0006] To this end, the present application provides a tuned liquid damper structure under the helipad on the top floor of a super high-rise building to solve the problem of limited structural size of the water tank body after the helipad is built on the super high-rise building in the prior art.

[0007] In order to achieve the above objectives, this application provides the following technical solutions:

[0008] A tuned liquid damper structure under a helipad on the top floor of a super high-rise building comprises a top plate, a plurality of elevator rooms built on the top of the top plate, and a helipad supported on the tops of the plurality of elevator rooms, wherein the plurality of elevator rooms are arranged at intervals. The tuned liquid damper structure under the helipad on the top floor of the super high-rise building further comprises a tuned liquid damper, wherein the tuned liquid damper comprises a first water tank body connected to the top plate, wherein the first water tank body is located between the top plate and the helipad. The tuned liquid damper structure under the helipad on the top floor of the super high-rise building further comprises a second water tank body connected to the top plate, wherein the first water tank body and the second water tank body are connected via a drainage pipe.

[0009] Preferably, the top wall of the first water tank body is integrally formed on the apron, one side wall of the first water tank body is integrally formed on a side wall of the elevator room, the other side wall of the first water tank body is integrally formed on a side wall of the second water tank body, and the drainage pipe is opened on the common side wall of the first water tank body and the second water tank body.

[0010] Preferably, the top wall of the second water tank body is integrally formed on the apron, the bottom wall of the second water tank body is lower than the bottom wall of the first water tank body, and the bottom wall of the drainage pipe is flush with the bottom wall of the first water tank body.

[0011] Preferably, the outer side wall of the second water tank body is connected to a liquid level pipe for observing the liquid level of water in the second water tank body, and both ends of the liquid level pipe are respectively connected to the chamber of the second water tank body, and the two ends are arranged in sequence along the height direction of the second water tank body.

[0012] Preferably, there are two elevator rooms, the first water tank body is located between the two elevator rooms, and the second water tank body is located on one side of the virtual line between the two elevator rooms.

[0013] Preferably, the first water tank body, the second water tank body and the helipad are all reinforced concrete structures.

[0014] Preferably, a wiring through hole is provided on the top wall of the second water tank body, and the wiring through hole passes through the apron.

[0015] Preferably, the first water tank body and the second water tank body are both rectangular parallelepiped structures, the length*width*height of the first water tank body is 14*7.8*6.15m, and the size of the drainage pipe is 30*30cm.

[0016] Preferably, the liquid level of water in the first water tank is 4.11 m.

[0017] This application has the following advantages:

[0018] The helipad is built on top of multiple elevator rooms, which support the helipad. The first water tank body is built between the roof and the helipad. Since the space between the roof and the helipad is effective, the height setting of the first water tank body is limited by the height between the roof and the helipad. Therefore, a second water tank body is built and connected to the first water tank body, so that the reduced water storage space of the first water tank body is compensated by the second water tank body to ensure the minimum fire water consumption.

[0019] The first water tank body and the second water tank body are not directly connected to each other, that is, to form a complete storage cavity, but the chambers of the two water tank bodies are connected through a drainage pipe. This is because the structure (including the slurry column) and size design of the first water tank body need to meet the design standards to achieve a good vibration reduction effect. Directly expanding the size of the first water tank body in one direction (such as the width direction and the length direction) will destroy the original vibration reduction structure of the first water tank body.

[0027] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0028] In the description of the present application: the terms "inside" and "outside" refer to the inside and outside of the corresponding component contours; the terms "first" and "second" are intended to distinguish the objects referred to, and the terms "including", "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units that have been explicitly listed, but may also include other steps or units that are not explicitly listed but are inherent to these processes, methods, products or equipment, or steps or units added based on further optimization schemes conceived in the present application.

[0029] Figure 2 and Figure 3 The middle dashed line represents the occluded structural features.

[0030] The present application discloses a tuned liquid damper structure under the helipad on the top floor of a super high-rise building, comprising a top plate 11, multiple elevator rooms 2 built on the top of the top plate 11, and a helipad 3 supported on the top of the multiple elevator rooms 2, wherein the multiple elevator rooms 2 are arranged at intervals, and further comprising a tuned liquid damper. The tuned liquid damper comprises a first water tank body 4 connected to the top plate 11, and the first water tank body 4 is located between the top plate 11 and the helipad 3. The tuned liquid damper structure under the helipad on the top floor of the super high-rise building further comprises a second water tank body 5 connected to the top plate 11, and the first water tank body 4 and the second water tank body 5 are connected via a drainage pipe 41.

[0031] The helipad 3 is built on the top of multiple elevator rooms 2, and the multiple elevator rooms 2 support the helipad 3. The first water tank body 4 is built between the top plate 11 and the helipad 3. Since the space between the top plate 11 and the helipad 3 is effective, the height setting of the first water tank body 4 is limited by the height between the top plate 11 and the helipad 3. Therefore, a second water tank body 5 is built, and the second water tank body 5 is connected to the first water tank body 4, so that the reduced water storage space of the first water tank body 4 is compensated by the second water tank body 5 to ensure the minimum fire-fighting water.

[0032] It should be further emphasized here that the first water tank body 4 and the second water tank body 5 are not directly connected to each other, that is, to form a complete storage cavity, but the chambers of the two water tank bodies are connected through the drainage pipe 41. This is because the structure (including the slurry column 42) and size design of the first water tank body 4 need to meet the design standards in order to achieve a good vibration reduction effect. Directly expanding the size of the first water tank body 4 in one direction (such as the width direction and the length direction) will destroy the original vibration reduction structure of the first water tank body 4.

[0033] The top wall of the first water tank body 4 is integrally formed with the landing pad 3, one side wall of the first water tank body 4 is integrally formed with a side wall of the elevator building 2, and the other side wall of the first water tank body 4 is integrally formed with a side wall of the second water tank body 5. A drainage pipe 41 is provided in the common side wall of the first water tank body 4 and the second water tank body 5. The three side walls of the first water tank body 4 are shared with the other structural elements of the building, which not only reduces construction costs but also increases structural strength. The drainage pipe 41 is a hole reserved during construction.

[0034] The first water tank body 4, the second water tank body 5 and the helipad 3 are all reinforced concrete structures.

[0035] The top wall of the second water tank body 5 is integrally formed on the apron 3, the bottom wall of the second water tank body 5 is lower than the bottom wall of the first water tank body 4, and the bottom wall of the drainage pipe 41 is flush with the bottom wall of the first water tank body 4. In order to further increase the water storage space of the second water tank body 5, a reserved water pool can be opened on the top floor. When the second water tank body 5 is constructed, the structure of the second water tank body 5 and the reserved water pool are connected together, that is, the pool space of the reserved water pool is also formed as part of the chamber of the second water tank body 5; it should be noted here that the second water tank body 5 does not take into account the function of vibration reduction, but only serves the function of water storage. Therefore, the size can be increased if the spatial structure allows to increase the water storage capacity.

[0036] A liquid level pipe 51 for observing the liquid level of the water in the second water tank body 5 is connected to the outer wall of the second water tank body 5. The two ends of the liquid level pipe 51 are respectively connected to the chamber of the second water tank body 5, and the two ends are arranged in sequence along the height direction of the second water tank body 5. The liquid level pipe 51 is transparent or translucent. In this way, people can determine the liquid level of the water in the second water tank body 5 from the outside by the liquid level of the liquid level pipe 51, and then determine the liquid level of the water in the first water tank body 4, so as to determine whether water needs to be added to the second water tank body 5.

[0037] There are two elevator rooms 2 , the first water tank body 4 is located between the two elevator rooms 2 , and the second water tank body 5 is located on one side of the virtual line between the two elevator rooms 2 .

[0038] A wiring through hole is provided on the top wall of the second water tank body 5 , and the wiring through hole passes through the apron 3 .

[0039] Both the first water tank housing 4 and the second water tank housing 5 are rectangular parallelepiped structures. The length, width, and height of the first water tank housing 4 are 14 x 7.8 x 6.15 meters, and the drainage conduit 41 is 30 x 30 cm. The length, width, and height ratios of the first water tank housing 4 are fixed (i.e., 14:7.8:6.15). Different sizes of first water tank housings 4 can be designed based on the actual construction environment. The drainage conduit 41 is minimized to avoid affecting the vibration damping structure of the first water tank housing 4.

[0040] The liquid level of the water in the first water tank body 4 is 4.11 m. The liquid level of the water in the first water tank body 4 is dynamically maintained at a height of 4.11 m.

[0041] Among them, in the fire-fighting water, the fire-fighting pipe connected to the first water tank body 4 and the water inlet pipe for replenishing water to the first water tank body 4 are not shown in the figure.

[0042] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0043] The present application has been described in a relatively specific and detailed manner through general explanations and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations may be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by such conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
