[0001] This invention belongs to the field of water tank technology, and in particular relates to a new concrete roof structure for an existing water tank. Background Technology

[0002] During the construction of a hydropower station, several water tanks need to be built to supply water for construction. After the hydropower station is completed, some of the water tanks will be combined with permanent ones and converted for other purposes, such as fire-fighting water tanks, in order to save costs. At this time, it is necessary to add roofs to the existing water tanks. Summary of the Invention

Detailed Implementation

[0016] like Figures 1 to 4 As shown, this invention provides a new concrete roof structure for an existing water tank. It includes frame columns 1, roof beams 2, and roof panels 3. The roof beams 2 form a crisscrossing mesh structure. The tops of the frame columns 1 are connected to the intersections of the roof beams 2. The roof panels 3 are mounted on the roof beams 2, and parapet walls 4 are provided around all four sides of the roof panels 3. Access holes 5 are also provided in the roof panels 3. This design allows for the utilization of the existing water tank, enabling it to be modified for other uses, reducing redundant investment, achieving cost reduction and efficiency improvement. Furthermore, the roof structure has strong load-bearing capacity, eliminating the need for significant alterations to the existing water tank and ensuring its structural safety. The parapet walls 4, located around the roof panels 3, not only maintain safety but also allow for the application of waterproof brickwork at the bottom to prevent water seepage into the waterproof layer.

[0017] like Figure 5 and Figure 6 As shown, as one implementation method, the bottom of the frame column 1 is provided with an independent foundation 6, the cross-sectional area of ​​which is larger than that of the frame column 1. This arrangement increases the contact area between the bottom of the frame column 1 and the pool floor, and lowers the overall center of gravity of the independent foundation 6 and the frame column 1, thus improving the stability of the frame column 1. A sloping transition is made at the top of the frame column 1, making the connection between the independent foundation 6 and the frame column 1 more natural. Before pouring the independent foundation 6, the contact surface of the pool floor slab needs to be roughened to improve the connection effect between the independent foundation 6 and the pool floor slab.

[0018] Specifically, the spacing between adjacent frame columns 1 is the same as the spacing between the existing water tank tie plates. This arrangement further improves the stability of the water tank.

[0019] like Figures 9 to 14 As shown, in one implementation, the roof panel 3 extends upward around the access hole 5 to form a platform 7, and a cover plate 8 is provided on the platform 7. This arrangement facilitates access to the water tank for maintenance, and the platform 7 and cover plate 8 prevent water from the roof panel 3 from flowing into the water tank, effectively avoiding contamination of the water tank.

[0020] Specifically, stiffening strips 9 are provided on the inner side of the cover plate 8. This design improves the strength and load-bearing capacity of the cover plate 8, preventing deformation under stress and avoiding the possibility of maintenance personnel falling into the access hole 5 due to deformation of the cover plate 8, thus enhancing the safety of the cover plate 8. The stiffening strips are welded from angle steel and flat steel, forming a square tubular shape. Figure 14 As shown, this can further improve the strength of the cover plate 8, and the angle steel and flat steel are easy to obtain on the construction site and are more convenient to process.

[0021] In this embodiment, the cover plate 8 is provided with opening holes 10 around its perimeter. The opening holes 10 include a central hole 11 and side holes 12 on both sides of the central hole 11. The central hole 11 and the side holes 12 are connected to allow the T-shaped rod 19 to enter the opening holes 10. With the above arrangement, the cover plate 8 can be opened easily. Generally, a T-shaped rod 19 is used, with its end entering the inner side of the cover plate 8 through the opening hole 10. Then, the T-shaped rod 19 is rotated 90 degrees, so that the end of the T-shaped rod 19 rotates from the position opposite to the side hole 12 to the bottom of the cover plate 8. At this time, the T-shaped rod 19 is lifted, and the end of the T-shaped rod 19 can be locked under the cover plate 8, thereby driving the cover plate 8 to open the cover plate 8.

[0022] The opening 10 is surrounded by a stiffening plate 13, which is fixedly connected to the cover plate 8. The stiffening plate 13 can improve the strength of the cover plate 8 around the opening 10, prevent the opening 10 from wearing and deforming due to long-term use, and improve the service life of the cover plate 8.

[0023] As one implementation, the parapet wall 4 includes a high wall 14 and a low wall 15, which are alternately arranged.

[0024] Specifically, the top of the parapet wall 4 is provided with a thickened part 16, the thickness of which is twice the thickness of the parapet wall 4. The thickened part 16 faces the inner side of the parapet wall 4, which plays a certain role in shielding and preventing rainwater from flowing directly down the wall of the parapet wall 4, thereby improving the service life of the roof structure.

[0025] Specific embodiments of the present invention: First, independent foundation 6 is placed on the existing water tank 17 base plate, using an enlarged foundation type, with a lower surface size of 1400mm×1400mm and an upper surface size of 600mm×600mm. The spacing of independent foundation 6 is the same as the spacing of the existing water tank 17 inclined tie plate 18. Before pouring the independent foundation 6, the contact surface of the water tank base plate needs to be roughened.

[0026] Subsequently, frame column 1 was placed on independent foundation 6, with a cross-sectional dimension of 400mm×400mm, and the number was the same as that of independent foundation 6. Frame column 1 and independent foundation 6 were erected and cast together.

[0027] Subsequently, the roof beam 2 is located at the top of the frame column 1, with a cross-sectional dimension of 300mm×900mm. The roof beam 2 is supported on the top of the existing water tank 17 and the inclined tie plate 18.

[0028] Subsequently, the roof panel 3 is located on top of the frame column 1 and the roof beam 2. The panel thickness is 200mm. The roof panel 3 is supported on the top surface of the four surrounding walls of the existing water tank 17. The roof panel 3 and the roof beam 2 are cast together in a mold.

[0029] Subsequently, the manhole 5 is located on the roof panel 3, near the existing steel ladder of the pool 17. The net dimensions of the manhole 5 are 1000mm × 1000mm. The manhole 5 has a platform 7 around it, with a height of 200mm and a width of 100mm. The manhole 5 is cast together with the roof panel 3.

[0030] Subsequently, parapet walls 4 were installed around the roof panel 3, with alternating heights. The heights of parapet walls 4 were 1650mm and 1050mm, and the thickness was 120mm, with the top thickened to 240mm.

[0031] Finally, the manhole 5 cover plate 8 is made of stainless steel and consists of equilateral angle steel 70×6, flat steel-64×5 and 6mm thick patterned steel plate. The manhole 5 cover plate 8 has opening holes 10 around its perimeter and stiffening plates 13 made of flat steel-64×5 are placed next to the opening holes 10. After the manhole 5 cover plate 8 is made, it is placed on the manhole 5.

[0032] This invention forms the roof structure of the existing water tank 17 by setting up frame columns 1, roof beams 2 and roof panels 3. The roof beams 2 form a grid structure by crisscrossing. The top of the frame columns 1 is connected to the intersection point of the roof beams 2. The roof panels 3 are set on the roof beams 2. This can avoid major changes to the existing water tank 17, ensure the structural safety of the existing water tank 17, and save construction costs.

[0033] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
