Description

Technical Field

[0001] This utility model relates to a vibration reduction structure for high-rise buildings, specifically a rooftop swimming pool with building vibration reduction function. Background Technology

[0002] High-rise buildings have become the mainstream form of new construction in my country, and vibration reduction is a key design focus. Due to their high flexibility, high-rise buildings have relatively long natural periods, resulting in significant structural dynamic responses under wind loads and earthquakes. Simultaneously, with continuously rising housing prices and strained land and water resources, the rational conservation of land and water use is crucial.

[0003] Structural vibration control technology is mainly based on two principles: (1) changing the dynamic characteristics of the structure, such as modifying the structural stiffness; (2) installing additional damping devices that can absorb and dissipate some of the structural energy, of which TLD is a typical passive energy dissipation device.

[0004] Currently, TLD (Transient Dynamic Damping) systems used in building construction often employ an excessive number of water tanks, resulting in high manufacturing costs, large space requirements, and drawbacks such as the inability to reuse the water. Furthermore, shallow-water TLDs have shallow water levels and low water mass, limiting their vibration reduction effect. Deep-water TLDs, on the other hand, have higher water levels and greater water mass, making them ideal for rooftop swimming pools. Existing research indicates that TLD systems achieve optimal vibration reduction when their swaying frequency is close to and slightly lower than the building's natural frequency. Therefore, controlling the water level h within the swimming pool to achieve the desired swaying frequency remains a challenge.

[0005] Swimming pool dampers (TLDs) installed on building rooftops can reduce vibration and dissipate energy through the inertia and viscosity of the liquid within the pool. Furthermore, rooftop swimming pools make better use of space, require no floor area, offer unobstructed views, and allow for the reuse of water resources. Utility Model Content

The swimming pool is installed on the rooftop, and the water in the pool is connected to the water pipes on each floor, thus saving land and water.

[0007] This utility model provides the following technical solution:

[0008] A rooftop swimming pool with building vibration reduction function is located on the roof of a building. It includes a main swimming pool and a covered water level regulating pool. The main swimming pool and the water level regulating pool are connected by a passage. The main swimming pool is equipped with a drain pipe, an emergency drain pipe and a ladder.

The water level regulating pool is equipped with a faucet, a water pipe, an automatic water level regulator and a hollow copper float. A faucet is installed on the water pipe and an automatic water level regulator is installed on the faucet. The automatic water level regulator is connected to the hollow copper float in the water level regulating pool.

[0009] Furthermore, the drainage pipe is used to connect the main swimming pool to the water pipes on each floor or the external greening pipes.

[0010] Furthermore, the emergency drainage pipe is connected to the drainage pipes of the floors below the building.

[0011] Furthermore, the escalators are located at the four corners of the main swimming pool.

[0012] Furthermore, the hollow copper float is located in the water level regulating tank, and the automatic water level regulator controls the on / off state of the faucet based on the position and height of the hollow copper float.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 This utility model discloses a rooftop swimming pool with building vibration reduction function. The swimming pool is located on the roof 3 of a building and includes a main swimming pool 1 and a covered water level regulating pool 2. The main swimming pool 1 and the water level regulating pool 2 are connected by a channel 1a. The main swimming pool 1 is equipped with a drain pipe 1b, an emergency drain pipe 1c and a ladder 1d. The channel 1a, drain pipe 1b and emergency drain pipe 1c are located on the side of the main swimming pool 1. The water level regulating pool 2 is equipped with a faucet 2a, a water pipe 2b, an automatic water level regulator 2c and a hollow copper float 2d. The faucet 2a is installed on the water pipe 2b and the automatic water level regulator 2c is installed on the faucet 2a. The automatic water level regulator 2c is connected to the hollow copper float 2d in the water level regulating pool 2.

[0021] The bottom of the main swimming pool 1 is a slope with a gradually decreasing height.

[0022] Drainage pipe 1b is used to connect the main swimming pool 1 to the water pipes on each floor or the external greening pipes.

[0023] Emergency drainage pipe 1c connects to the drainage pipes of the floors below the building.

[0024] Escalators 1d are located at the four corners of the main swimming pool 1. Escalators 1d are arranged at the four corners of the main swimming pool 1 to facilitate swimmers getting in and out of the water.

[0025] The hollow copper float 2d is positioned at a suitable location in the water level regulating tank 2. The hollow copper float 2d is connected to the automatic water level regulator 2c. The automatic water level regulator 2c controls the opening and closing status of the faucet based on the position and height of the hollow copper float 2d.

[0026] This utility model connects the water level regulating tank 2 and the main swimming pool 1 together through pipe 1a, and uses faucet 2a and automatic water level regulator 2c to jointly regulate the water level of the water level regulating tank 2, thereby regulating the water level of the swimming pool 1 through the principle of communicating vessels. The main switch of the water level regulating tank 2 can be set on the wall of the floor below. The water in the swimming pool can be connected to the water pipes or greening pipes of each floor through the drain pipe 1b to realize the reuse of water.

[0027] The water in the main swimming pool of this invention can be in a circulating state. If the swimming pool needs to be cleaned, the water can be discharged into the sewer pipe through the drain pipe or emergency drain pipe. The swimming pool of this invention can also be used as a water storage tank. The water in the swimming pool can be discharged into the nearby green belt through the drain pipe, thereby realizing the reuse of water resources.

[0028] This utility model also provides a design method for a rooftop swimming pool type damper.

[0029] Step 1: Determine the natural period, frequency, and mass of the existing building using existing data;

[0030] Step 2: Obtain the dimension L of the swimming pool on the roof of the high-rise building along the vibration direction;

[0031] Step 3: Design the water level of the swimming pool according to the natural frequency of the building structure, so that the natural frequency of the rooftop swimming pool is close to the natural frequency of the building structure, and control the ratio of water volume to building mass to be about 1%.

[0032] This invention analyzes the TLD formed by a rooftop swimming pool using a TLD model based on the lumped mass method. The TLD model based on the lumped mass method is described below.

[0033] When using the TLD model based on the lumped mass method, the calculation of each parameter is as follows:

[0034] Rectangular TLD:

[0035]

[0036]

[0037]

[0038]

[0039]

[0040] In the formula: M is the mass of the water, L is the dimension of the swimming pool in the direction of vibration, g is the acceleration due to gravity, and h is the depth of the water in the swimming pool. The first-order oscillation frequency of the TLD. The damping ratio for water level sloshing in the tank can be calculated using the logarithmic decay method.

[0041] It should be noted that the main core of this utility model is to design the water level of an existing rooftop swimming pool to change the sloshing frequency of the liquid, making it closer to the vibration frequency of the building structure, thereby achieving the vibration reduction effect of a TLD. The idea of ​​using an existing rooftop swimming pool to form a TLD is superior to the conventional practice of setting up a dedicated TLD.

[0042] This invention achieves vibration reduction by controlling the water level of a rooftop swimming pool in a high-rise building, thus combining the functions of a swimming pool and a tuned liquid damper (TLD). Determining a suitable water level optimizes the TLD's water quality and sloshing frequency, thereby reducing vibrations in the high-rise building structure under seismic and wind loads without significantly increasing construction costs, thus improving the building's seismic performance. Unlike conventional TLD design methods, this invention does not require numerous small water tanks as TLDs; instead, it utilizes the existing rooftop swimming pool, reducing vibration reduction costs without compromising the pool's normal functionality.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
