Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, specifically, it relates to an anti-buoyancy anchor waterproof joint. Background Technology

[0002] Currently, anti-buoyancy anchors are widely used at the bottom of foundations in domestic construction projects to address buoyancy issues caused by high groundwater levels. The end anchor bars of the anti-buoyancy anchors need to penetrate the waterproofing layer of the foundation slab and be anchored within the slab, resulting in a waterproofing node at the junction of the anchor and the waterproofing layer, preventing the waterproofing layer from completely sealing the foundation. Since there are usually many anti-buoyancy anchors, improper waterproofing at this node during the foundation slab waterproofing construction can easily lead to large-scale water leakage in the foundation slab.

[0003] Currently, waterproofing construction at anchor bolt joints often follows the construction methods for pile head waterproofing, using relatively outdated waterproofing materials and processes with significant defects: the waterproofing material cannot adhere tightly to the anchor bolt, resulting in poor overall waterproofing structure, which easily leads to leakage of the base slab and consequently poor waterproofing effect; if anchor bolt misalignment is not corrected in time during grouting, it will lead to severe misalignment of the anchor bolt after grouting, so it is also necessary to ensure that the anchor bolt is centered in the foundation pit. Utility Model Content

[0004] To address the shortcomings of existing technologies, the anti-buoyancy anchor waterproof joint provided by this utility model has good overall integrity and can improve waterproof performance. By cooperating with the clamping component and the rubber cup mouth, it limits the anti-buoyancy anchor and thus solves the problem of anchor displacement.

[0005] The present invention adopts the following technical solution.

[0006] A waterproof joint for anti-buoyancy anchor rods includes an anti-buoyancy anchor rod, and the waterproof joint for anti-buoyancy anchor rods further includes, from bottom to top, a foundation, a concrete pad, a waterproof coating layer, a first waterproof membrane layer, a rubber cup, a second waterproof membrane layer, and an underground structure base plate; the bottom of the anti-buoyancy anchor rod is connected to the foundation, and the top of the anti-buoyancy anchor rod is provided with an expansion waterstop strip;

[0007] The inner wall of the rubber cup mouth is provided with several clamping components, which are connected to the anti-buoyancy anchor rod steel bars. Each clamping component includes a pad, a connector and a clamping part. The pad is fixedly connected to the inner wall of the rubber cup mouth, one end of the connector is fixedly connected to the pad, and the other end is fixedly connected to the clamping part.

[0008] Furthermore, the clamping part is a plastic retaining ring with an opening, and the inner wall of the plastic retaining ring is provided with several anti-slip rubber strips; the side of the pad near the rubber cup opening is designed in an arc shape.

[0009] Furthermore, the waterproof coating layer is applied around the anti-buoyancy anchor rod, with a radius of not less than 250 mm and a thickness of 1-2 mm.

[0010] Furthermore, the waterproof coating layer includes a first waterproof coating layer and a second waterproof coating layer, which are arranged sequentially from bottom to top;

[0011] The first waterproof coating layer uses a cement-based penetrating crystalline waterproof coating, and the second waterproof coating layer uses a non-curing rubber asphalt waterproof coating.

[0012] Furthermore, the thickness of the first waterproof membrane layer is 1.5-2.5mm, and the thickness of the second waterproof membrane layer is 4-5mm.

[0013] The beneficial effects of this utility model are as follows, compared with the prior art:

[0014] 1. This application forms a synergistic waterproofing system by sequentially installing a concrete pad layer, a waterproof coating layer, a first waterproof membrane layer, a rubber cup-shaped rim, and a second waterproof membrane layer from bottom to top. Non-curing rubber asphalt sealant is injected at the joint between the anti-buoyancy anchor and the second waterproof membrane layer. Through its dual bonding properties with the membrane and anchor, the integrity and waterproofing performance of the waterproof joint are improved.

[0015] 2. This utility model uses the adaptability of the arc-shaped pad and the rubber cup mouth to connect the anti-buoyancy anchor bar, which can be squeezed into the open plastic retaining ring, thereby completing the anti-buoyancy anchor bar limiting; during the grouting process, this structure can form a stable radial constraint on the anchor bar, effectively resisting the displacement caused by grouting pressure and soil disturbance, ensuring that the anchor bar is always in the designed position and avoiding damage to the waterproof node caused by misalignment, thus achieving a dual improvement in structural safety and waterproof performance.
