Description
Technical Field
[0001] The present application relates to the field of anti-floating anchor rod waterproofing, and in particular to an anti-floating anchor rod waterproofing node structure suitable for winter construction. Background Art
[0002] With the increasing scarcity of available urban construction land and the rapid advancement of science and technology, basements are being buried deeper and deeper. However, underground construction inevitably requires consideration of the impact of groundwater buoyancy on buildings. Groundwater buoyancy can cause deformation in underground structures, impacting their use or even damaging them, resulting in irreparable economic losses and adverse social impacts. Therefore, to prevent basements from buoying, anti-floating measures are often employed. Anti-floating anchor rods are commonly used in engineering practice as a countermeasure.
[0003] However, the anti-floating anchor rods have to penetrate the waterproof layer of the basement floor, which increases the possibility of water seepage and is a weak link in the waterproof construction. Therefore, a waterproof structure needs to be set up at the position of the anti-floating anchor rods. The general waterproof structure can play a good waterproof role in summer construction. However, in winter construction, due to the influence of temperature, materials such as penetrating crystallization and waterproof mortar are prone to freeze-thaw cracking, and the waterproof effect of the waterproof structure cannot be guaranteed, which may cause construction quality problems.

[0026] The following is combined with Figure 1-3 This application is described in further detail.
[0027] The embodiment of the present application discloses an anti-floating anchor rod waterproof node structure suitable for winter construction. Figure 1 and Figure 2 A floating anchor rod waterproof node structure suitable for winter construction includes a plain concrete cushion layer 11, an anti-floating anchor rod 9, and a steel pad 10. The anti-floating anchor rod 9 is anchored into the ground, and the plain concrete cushion layer 11 is cast at the bottom of the foundation pit. The top of the anti-floating anchor rod 9 extends out of the plain concrete cushion layer 11. After the raft slab is cast, the anti-floating anchor rod 9 is anchored into the raft slab. The steel pad 10 is sleeved on the anti-floating anchor rod 9, and the steel pad 10 is fitted with the plain concrete cushion layer 11. Two water stop rings 91 are also provided on the anti-floating anchor rod 9. The two water stop rings 91 are spaced apart. After the raft slab is cast, the two water stop rings 91 are both inside the raft slab.
[0028] An anti-floating anchor rod waterproof node structure suitable for winter construction also includes a permeable crystallization layer 1, an insulating asphalt layer 2, a waterproof additional layer, a first layer of waterproof coiled material 4, a second layer of waterproof coiled material 6, a rubber ring 7 and an insulating sleeve 8.
[0029] The infiltration crystallization layer 1 is painted on the steel base plate 10, and is also painted on a position 5 cm away from the surrounding of the steel base plate 10. The infiltration crystallization layer 1 is painted using infiltration crystals stored in a heat preservation manner.
[0030] The insulating asphalt layer 2 is overlaid on the surface of the permeable crystal layer 1. Heat-treated, non-solidified asphalt is poured onto the permeable crystal layer 1, solidifying to form the insulating asphalt layer 2. This insulates the permeable crystal layer 1 and protects it from freezing during winter construction. After the insulating asphalt layer 2 is laid, nuts are screwed into the anti-floating anchor rods 9, followed by the installation of the first non-solidified asphalt layer 3. This first non-solidified asphalt layer 3 is poured onto the insulating asphalt layer 2. This layer insulates both the insulating asphalt layer 2 and the permeable crystal layer 1, further protecting the permeable crystal layer 1.
[0031] Anchor holes are opened on the first layer of waterproof membrane 4, and the diameter of the anchor holes is 2 cm larger than the diameter of the anti-floating anchor 9. The first layer of waterproof membrane 4 is fully adhered and laid on the first non-solidified asphalt layer 3, so that the anti-floating anchor 9 is passed through the holes of the anti-floating anchor 9 and the anti-floating anchor 9 is located in the center of the anchor hole.
[0032] After the first layer of waterproof membrane 4 is laid, the second non-solidified asphalt layer 5 is poured on the first layer of waterproof membrane 4, and then the rubber ring 7 is put on the anti-floating anchor rod 9. The rubber ring 7 includes a circular plate 71 and a cylinder 72. The cylinder 72 is fixedly connected to one surface of the circular plate 71, and the cylinder 72 is coaxially arranged with the hole in the circular plate 71. When installing the rubber ring 7, the circular plate 71 is hot-melt fixedly connected to the first layer of waterproof membrane 4, and the anti-floating anchor rod 9 is located in the center position of the cylinder 72, and a nut is screwed into the anti-floating anchor rod 9 so that the nut is located in the cylinder 72, and then non-solidified asphalt is poured into the cylinder 72, and the non-solidified asphalt covers the nut.
[0033] The second layer of waterproof membrane 6 is provided with a cylindrical hole 72 , and the second layer of waterproof membrane 6 is laid on the first layer of waterproof membrane 4 , with the cylindrical hole 72 located in the cylindrical hole 72 .
[0034] After the second layer of waterproof membrane 6 is constructed, a waterproof protective layer 12 is poured to cover the waterproof structure, thereby providing good protection for the waterproof structure.
[0035] refer to Figure 2 and Figure 3The insulation cover 8 is placed on the anti-floating anchor rod 9. Two ridges 81 are provided on the inner wall of the insulation cover 8. The two ridges 81 correspond to the two water stop rings 91. After the insulation cover 8 is placed on the anti-floating anchor rod 9, the corresponding ridges 81 abut against the bottom surface of the water stop ring 91, thereby fixing the insulation cover 8 on the anti-floating anchor rod 9 and playing a role in heat preservation for the anti-floating anchor rod 9. This prevents the heat conduction through the anti-floating anchor rod 9 from causing the insulating asphalt layer 2 and the permeable crystal layer 1 to freeze. When pouring the raft slab, the insulation cover 8 is removed and can be recycled for subsequent use.
[0036] The implementation principle of the anti-floating anchor rod waterproof node structure suitable for winter construction in an embodiment of the present application is: use the insulated stored permeable crystals to brush the permeable crystal layer 1, and use heated non-solidified asphalt to pour on the surface of the permeable crystal layer 1, which has a good thermal insulation effect on the permeable crystal layer 1, prevents the permeable crystal layer 1 from freezing and thawing and cracking during winter construction, and ensures the waterproof effect of the anti-floating anchor rod 9 waterproof structure during winter construction. In addition, by providing the insulation cover 8, it can also prevent the outdoor temperature from being transmitted to the position of the permeable crystal layer 1 through the anti-floating anchor rod 9, thereby further protecting the permeable crystal layer 1.
[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
