Description

Technical Field

[0001] This utility model belongs to the field of decoration and renovation technology, specifically relating to a prefabricated partition wall for underground powerhouses of hydropower and pumped storage power stations. Background Technology

[0002] Hydropower and pumped-storage power plants typically utilize underground powerhouses due to abundant groundwater and the resulting humid environment. In current engineering practice, the fire-resistant walls of underground powerhouses are usually constructed using 240mm thick autoclaved aerated concrete (AAC) brick masonry. Specifically, the masonry walls are built using 240mm AAC bricks (strength ≥ MU10), reinforced with φ6@200 (two-way) steel bars on both sides, and secured with φ6 tie bars @600 in a staggered pattern, finished with a 20mm thick 1:2.5 cement mortar plaster. This masonry wall technique has the following disadvantages:

[0003] (1) Since the underground factory has a high floor height, most of them exceed 4 meters, a lot of structural columns and connecting beams need to be added. At this time, scaffolding needs to be erected when building the walls, which is very difficult and dangerous, and not conducive to safe construction.

[0004] (2) Construction organization typically involves constructing the main structure and masonry walls first, followed by the installation of mechanical and electrical equipment. Many ventilation openings and cable openings need to be reserved in the masonry walls. Due to limitations imposed by the manufacturer's mechanical and electrical equipment and inadequate coordination between upstream and downstream professionals, the openings are often improperly reserved or not pre-reserved during construction, necessitating the demolition of the 240mm thick autoclaved lime-sand brick masonry wall. Sometimes, even after mortar, putty, and paint have been applied, new openings are required. Masonry walls often contain many hidden electrical wires, pipes, and other facilities; re-opening these openings may damage these internal facilities, pollute the operating environment, and result in difficulties in construction organization, complex construction processes, long construction times, and low efficiency, thus affecting the construction cycle.

[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] See Figures 1 to 3 This utility model provides a prefabricated partition wall for underground powerhouses of hydropower and pumped storage power stations, including a keel frame, filling material 6, panel 7, lower floor slab 9, concrete ground beam 10, upper floor slab 11, special screws 12 and bolts 13.

[0027] A concrete ground beam 10 is fixedly installed on the ground of the lower floor slab 9; a keel frame is assembled between the top surface of the concrete ground beam 10 and the upper floor slab 11 using bolts 13; the keel frame is filled with filling material 6; and multiple panels 7 are assembled on both sides of the keel frame using special screws 12.

[0028] In one specific implementation, the filling material 6 is made of hydrophobic rock wool board. The panel 7 is made of Botte fireproof board, a green and environmentally friendly new building material. It is a lightweight, fire-resistant, Class A non-combustible board made of silicate materials, mainly composed of calcium silicate, and is asbestos-free, possessing anti-mildew and anti-insect properties. The special screws 12 are self-tapping screws M4.8X25, and the bolts 13 are M12×100 stainless steel expansion bolts.

[0029] The concrete ground beam 10 has the same thickness as the prefabricated partition wall, and the height of the concrete ground beam 10 is not less than 200mm. By setting the concrete ground beam 10, the supporting strength and moisture-proof performance of the prefabricated partition wall can be effectively improved.

[0030] In one specific implementation, the keel frame includes a top keel 1, a bottom keel 2, a longitudinal keel 3, a transverse keel 4, and a reinforcing keel 5;

[0031] The top keel 1 is assembled and installed on the bottom surface of the upper floor slab 11; the bottom keel 2 is assembled and installed on the top surface of the concrete ground beam 10; between the top keel 1 and the bottom keel 2, multiple longitudinal keels 3 are set at vertical intervals; multiple transverse keels 4 are set parallel from top to bottom along the length direction perpendicular to the longitudinal keel 3.

[0032] Reinforcing keels 5 are installed along the length of multiple longitudinal keels 3, perpendicular to their length. These reinforcing keels 5 are mainly located around openings in the prefabricated partition wall, used to enhance the strength of the keels at these openings and other locations.

[0033] To enhance the structural stability and strength of the keel frame, the longitudinal keel 3 and the transverse keel 4 are welded together to form a whole.

[0034] In this application, the top keel 1, bottom keel 2, longitudinal keel 3, transverse keel 4, and reinforcing keel 5 can all be made of 50×50×5mm hot-dip galvanized steel pipe. The spacing of the longitudinal keels 3 shall not exceed 600mm, and the spacing of the transverse keels 4 shall not exceed 2400mm.

[0035] To facilitate the assembly of the keel frame, the top keel 1 is provided with a first fixing hole, and the top keel 1 is connected and fixed to the upper floor slab 11 by bolts 13 passing through the first fixing hole; the bottom keel 2 is provided with a second fixing hole, and the bottom keel 2 is connected and fixed to the concrete ground beam 10 by bolts 13 passing through the second fixing hole.

[0037] This utility model provides a prefabricated partition wall for underground powerhouses of hydropower and pumped storage power stations. It is a light steel keel glass board partition wall, which is a non-load-bearing fireproof partition wall with light steel keel as the frame and glass fireproof board as the panel. It has the advantages of being green, energy-saving and environmentally friendly, and having efficient and fast construction.

[0038] The prefabricated partition wall for the underground powerhouse of a hydroelectric and pumped storage power station provided by this utility model has the following advantages:

[0039] 1. During use, prefabricated buildings are more green, energy-efficient, and environmentally friendly, and are recyclable, meeting the requirements of sustainable development. Due to the characteristics of their panel specifications, they also possess the advantage of overall integrity; partition walls are often composed of several large wall panels spliced ​​together, resulting in efficient and rapid construction. During construction, strong technical expertise is often not required; assembly is simple, eliminating the need for traditional bricklayers, requiring only simple training to operate the equipment; no cement mortar is needed during construction, resulting in no littering and a safe and aesthetically pleasing appearance; and their comprehensive performance, including environmental protection, heat insulation, sound insulation, fire resistance, and economy, is superior.

[0040] 2. Prefabricated partition walls successfully avoid most of the uncontrollable problems associated with wet construction, reducing environmental pollution caused by wet work. This application directly uses pre-produced components, requiring only anchoring and splicing on-site, greatly improving construction accuracy, reducing process complexity, shortening construction time, and increasing efficiency and quality. Compared to traditional masonry partition walls, this application utilizes an industrialized production process, with prefabricated components mass-produced in the factory in a short time. Multiple prefabricated components only need to be transported to the site for assembly, significantly saving costs, shortening the construction period, and reducing labor and management costs.

[0041] 3. All pre-embedded pipelines such as wires and pipes are inside the light steel keel frame, which is easy to cut on site and makes it very convenient to open holes. On site, you only need to remove the panel to open the hole and add additional keel around the opening.

[0042] This invention can be mass-produced in a factory, reducing costs through large-scale production. Prefabricated partition walls allow for rapid on-site installation, significantly shortening the construction cycle and reducing labor and management costs. The entire system installation is dry work, facilitating on-site cutting and rapid construction; it also offers advantages such as convenient construction and efficient assembly / disassembly, thus meeting usage requirements. Prefabricated decoration structures greatly improve decoration efficiency, ensure decoration quality, are environmentally friendly, and can be widely applied to wall and other decoration projects.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
