[0002] High-rise buildings have become the mainstream form of new buildings in my country, and fire prevention is a key design concern. The "Code for Fire Protection Design of Buildings" provides the setting of fire-fighting facilities, which involves fire water tanks. Existing fire water tanks are usually equipped with tie nets (angle steel, etc.) to resist water pressure and ensure the integrity of the water tank structure.

[0003] Due to its high flexibility and other characteristics, high-rise buildings usually have a long natural vibration period. Under the action of wind loads and seismic loads, they will produce a large structural response. At this time, the tuned liquid damper (TLD) arranged on the building can reduce the vibration of the building through the sloshing of the water inside it. Conventional TLD devices usually arrange damping enhancement devices in the water tank to enhance the vibration reduction effect, but the damper is expensive and needs to be optimized and adjusted according to the natural frequency of the structure. The adaptation process is complicated and difficult to adjust after installation. Utility Model Content

[0040] The present embodiment is a fire water tank with enhanced TLD function, including a water tank body. A plurality of water guides are arranged in the water tank body. The water guides can convert the horizontal water flow direction in the body into a vertical direction, increase the collision of the water body, and enhance the energy consumption performance of the overall structure.

[0041] In this example, the water tank panels that make up the water tank body can be stamped stainless steel panels to prevent rust. The water tank panels include a number of petal-shaped protrusion panels and a number of flat box panels. Compared with the circular protrusions, the petal-shaped protrusion panels not only strengthen the middle stiffness and compressive resistance of the panels, but also improve the compressive resistance of the wall panels at the four corners, improve the stress performance of a single panel, and enhance the aesthetics.

[0042] The surface protrusions may be in the shape of petals, which not only enhances the out-of-plane stability of the plate when resisting water pressure, but also further improves the ornamental value of the water tank.

[0043] In this embodiment, relevant holes are left on the water tank body, including a water inlet pipe opening, a vent pipe opening, a water outlet pipe opening, a drain pipe opening and an overflow pipe opening.

[0044] In this embodiment, the water inlet is used to connect to the water inlet, and the water inlet should be provided with a corresponding rising stem gate valve and stop valve. At the same time, a float valve should be provided below the water inlet to detect whether the water body reaches the preset water level. The vent pipe is used to connect to the vent pipe, and a technical device to prevent debris from falling into the vent pipe is provided. The water outlet is used to connect to the outlet, and the inlet and outlet pipes should be provided with corresponding rising stem gate valves and check valves.

[0045] In this case, the drain pipe port is used to connect to the drain pipe, which should be set at the bottom of the water tank. The overflow pipe port is connected to the overflow pipe, the diameter of the overflow pipe should be more than twice that of the inlet pipe, and indirect drainage should be adopted.

[0046] In this embodiment, an inspection port is left at the top of the water tank body, and a ladder is provided for later inspection and cleaning of the water tank.

[0047] In this embodiment, a reinforcement mesh connecting the side walls is provided inside the water tank body, and the reinforcement mesh has longitudinal reinforcements and transverse reinforcements. Both the longitudinal reinforcements and the transverse reinforcements are corrugated reinforcements, and have crests and troughs of corrugated steel plates arranged alternately along the length direction of the reinforcements, so as to improve the lateral stiffness of a single reinforcement and reduce the single-piece thickness of the reinforcement mesh.

[0048] In this embodiment, a plurality of vertical tie bars are provided inside the water tank body, the vertical tie bars connect the top plate and the bottom plate of the water tank body, and the vertical tie bars can be corrugated tie bars.

[0049] In this example, a number of oblique slits are provided on the corrugated steel bars, and the oblique slits are arranged one by one in correspondence with the crests and troughs of the corrugated steel plate. The oblique slits can reduce the amount of steel used and allow water to pass through the oblique slits during the sloshing process, thereby increasing the contact area between the water and the steel bars, enhancing the interaction between the two, and enhancing the energy consumption performance of the water tank.

[0050] In this embodiment, the water guiding member has a π-shaped cross-section, and has an inlet section, an outlet section, and a connecting section connecting the inlet section and the outlet section, wherein the inlet section is used to guide water into the water guiding member and gradually change the flow direction of the water as the water enters the water guiding member; the water entering the water guiding member changes its flow direction after hitting the connecting section and flows out of the water guiding member under the guidance of the outlet section, and the outlet section gradually changes the flow direction of the water as the water flows out of the water guiding member.

[0051] In this example, the water guide can be in a straight line or a curved line, wherein the cross-sections of the inlet section and the outlet section in the curved line are arc-shaped curves; in the straight line, the inlet section is divided into an inlet oblique section, an inlet bending section and an inlet vertical section along the flow direction of the water body, the cross-sections of the inlet oblique section and the inlet vertical section are straight lines, and the inlet oblique section smoothly transitions to the inlet vertical section via the inlet bending section.

[0052] In this example, the height of the water guide should be adjusted according to the designed water level of the water tank, with the bottom of the water guide section being consistent with the designed water level. In this example, the water guide is fixed on the inner wall of the water tank body and on the tensioning net inside the water tank body.

[0053] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
