Description

Technical Field

[0001] This utility model relates to the field of single-slope double-T slab technology for buildings, and in particular to a prestressed concrete single-slope double-T slab for buildings. Background Technology

[0002] Prestressed concrete single-slope double-T slabs for construction are prefabricated prestressed concrete load-bearing components. They consist of a panel and two ribs forming a double-T-shaped basic structure. The core feature is that the panel has a single sloping angle, which is suitable for external drainage requirements. During manufacturing, prestressing tendons are used to apply compressive stress to the concrete in advance to compensate for its weak tensile strength. It has both large span load-bearing capacity and drainage function, and is widely used in the roofs or floors of buildings such as two-span external drainage factories and warehouses. It is easy to install and can reduce the risk of leakage.

[0003] Currently, most single-slope double-T slabs typically utilize the slope of their surface for drainage. However, although single-slope panels have a slope, rainwater tends to spread randomly along the panel surface when it falls. Some rainwater deviates from the intended drainage direction and lingers at the panel ends or roof edges, increasing the risk of water accumulation. Furthermore, after the double-T slabs are transported to the construction site using lifting rings, they need to be exposed to the elements for a long time, making them susceptible to wind, sun, rain, and corrosion, which affects the roof's appearance and durability.

[0004] Therefore, it is necessary to provide a new type of prestressed concrete single-slope double-T slab for construction to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a prestressed concrete single-slope double-T slab for building construction.

[0006] The prestressed concrete single-slope double-T slab for building provided by this utility model includes: a panel, rib beams symmetrically and fixedly connected to the bottom end of the panel, a crossbeam fixedly connected to the bottom end of the panel, and horizontal rib plates fixedly connected to both the left and right sides of the bottom end of the panel. Insulation components are installed inside the bottom ends of the rib beams. Insert rods are inserted into the inner walls of the four corners of the panel. A fixing rod is fixedly connected to the top end of each insert rod. A lifting ring is rotatably connected to the inner wall of the top end of the fixing rod. A first nut is threaded to the outer bottom end of each insert rod. Two washers are inserted through the outer bottom end of each insert rod. A strong spring is sleeved between the two washers on the outer bottom end of the insert rod. A second nut is threaded to the outer bottom end of each insert rod. Multiple guide grooves are formed on the top surface of the panel.

[0007] Preferably, the thermal insulation component includes a thermal insulation board, the inner wall of which has multiple prestressing tendon holes, glass wool is placed inside the prestressing tendon holes, and the inner wall of the glass wool is wrapped with prestressing tendons.

[0008] Preferably, the two sides of the crossbeam are fixedly connected to the adjacent side of the two rib beams, and the adjacent side of the two transverse rib plates is fixedly connected to the distant side of the two rib beams.

[0009] Preferably, the top end of the first nut contacts the bottom end of the panel.

[0010] Preferably, the bottom end of the first nut contacts the top end of the top washer, and the top end of the second nut contacts the bottom end of the bottom washer.

[0011] Preferably, the two ends of the strong spring are fixedly connected to the adjacent side of the two washers respectively.

[0012] Compared with related technologies, the prestressed concrete single-slope double-T slab for construction provided by this utility model has the following beneficial effects: This utility model, through the cooperation of a plug rod, nut, strong spring and washer, can stably connect the lifting equipment and the lifting ring when hoisting and transferring double T-plates, ensuring safe transfer. After the transfer and installation are completed, the lifting ring and other components can be easily removed, avoiding long-term exposure of the lifting ring to wind, sun and rain and corrosion, thus ensuring the cleanliness and durability of the roof appearance.

[0013] This invention effectively guides rainwater to flow in a preset direction by creating multiple drainage channels on the top surface of the panel. This greatly reduces the random diffusion of rainwater along the panel surface, lowers the risk of rainwater accumulating at the panel ends or roof edges, and further improves the drainage efficiency and reliability of the single-slope double-T panel.

[0014] This invention utilizes an internal insulation component at the bottom of the rib beam, along with insulation boards and glass wool, to provide excellent thermal insulation and protection for the prestressing tendons. This reduces the impact of external temperature changes on the prestressing tendons, ensures the stability of their performance, and thus helps maintain the overall structural strength of the double-T slab, extending its service life.

[0017] To make the objectives, technical solutions, and advantages 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 merely for explaining the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] Please see Figures 1 to 4 A prestressed concrete single-slope double-T slab for building construction includes a panel 1. Ribs 2 are symmetrically fixedly connected to the bottom end of the panel 1 to ensure that the panel 1 will not deform excessively when bearing load. A crossbeam 3 is fixedly connected to the bottom end of the panel 1 to connect the two ribs 2 into a whole, further enhancing the lateral stability of the double-T slab. Horizontal ribs 4 are fixedly connected to the left and right sides of the bottom end of the panel 1. The two sides of the crossbeam 3 are fixedly connected to the side of the two ribs 2 that are close to each other, and the two sides of the horizontal ribs 4 are fixedly connected to the side of the two ribs 2 that are far from each other. The horizontal ribs 4 can effectively distribute the load on the panel 1 and transfer it to the ribs 2. The insulation component is installed inside the bottom end of the rib beam 2. The insulation component includes a thermal insulation board 5, which is made of high-performance thermal insulation material. It can block the conduction of external temperature and play a good role in thermal insulation. The inner wall of the thermal insulation board 5 has multiple prestressing tendon holes, and glass wool 6 is placed in the prestressing tendon holes. Glass wool 6 is a material with good thermal insulation and sound insulation properties. It fills the prestressing tendon holes, which can not only further enhance the thermal insulation effect, but also play a role in buffering and protecting the prestressing tendons 7. The inner wall of the glass wool 6 is wrapped with prestressing tendons 7. These prestressing tendon holes are neatly arranged, providing space for the arrangement of prestressing tendons 7. Prestressing tendons 7 are the key components for realizing the prestressing function of the double T plate. They are tensioned before concrete pouring and relaxed after the concrete hardens, which can enable the concrete to bear pre-compression stress, thereby improving the crack resistance and load-bearing capacity of the double T plate. Insert rod 8 is inserted into the inner wall of the four corners of panel 1. The top of the insert rod 8 is fixedly connected to the top of the fixed rod 9. The top of the fixed rod 9 is rotatably connected to the inner wall of the top of the fixed rod 9. The hanging ring 10 can rotate freely on the inner wall of the top of the fixed rod 9. The bottom of the insert rod 8 is threadedly connected to the first nut 11. The top of the first nut 11 is in contact with the bottom of panel 1. Two washers 12 are inserted into the bottom of the insert rod 8. They have a certain thickness and strength to increase the force-bearing area and prevent damage to the insert rod 8 and panel 1 when the nut is tightened. The bottom of the first nut 11 is in contact with the top of the top washer 12. A strong spring 13 is sleeved between the two washers 12 on the outside of the insert rod 8. The two ends of the strong spring 13 are fixedly connected to the adjacent side of the two washers 12 respectively. The bottom of the insert rod 8 is threadedly connected to the second nut 14. The top of the second nut 14 is in contact with the bottom of the bottom washer 12. The top surface of the panel 1 has multiple drainage channels 15, which can guide rainwater to flow in a preset direction, prevent rainwater from spreading irregularly on the surface of the panel 1, and thus improve the drainage efficiency of the double T panel.

[0020] The working principle of the prestressed concrete single-slope double-T slab for building provided by this utility model is as follows: In the process of using the prestressed concrete single-slope double-T slab for this building, the hoisting operation is carried out first. When the double-T slab needs to be transferred, the operator connects the hook of the hoisting equipment with the lifting ring 10. Then the hoisting equipment is started. After the double-T slab is transported to the construction site and installed, if it is necessary to adjust or remove the lifting ring 10 and other components, the second nut 14 can be rotated. When the second nut 14 is rotated, the second nut 14 rotates at the bottom of the outer side of the insertion rod 8. Then the second nut 14 is removed. At this time, the washer 12 can be easily removed along with the strong spring 13 without the limitation of the second nut 14. Then the first nut 11 is turned and removed, so that the limitation of the insertion rod 8 is eliminated. Then the insertion rod 8 can be used to remove the fixing rod 9 and the lifting ring 10 to prevent the lifting ring 10 from being exposed to corrosion for a long time. When the double-T slab is put into use for drainage, rainwater falls on the top surface of panel 1. Since panel 1 has a single inclined slope and multiple guide channels 15, the rainwater will flow along the guide channels 15. The guide channels 15 guide the rainwater to flow in a preset direction, reducing the random diffusion of rainwater along the surface of panel 1. This allows the rainwater to flow more concentratedly to the drainage area, reducing the risk of water accumulating at the slab end or roof edge. In addition, for thermal insulation, thermal insulation components are installed inside the bottom end of the rib beam 2. The thermal insulation board 5 plays the main role in thermal insulation. The glass wool 6 installed in the prestressing tendon holes on its inner wall can provide thermal insulation protection for the prestressing tendons 7 that pass through it, reducing the impact of external temperature changes on the prestressing tendons 7, ensuring the performance stability of the prestressing tendons 7, and thus maintaining the overall structural strength and service life of the double-T slab.
