Description

Technical Field

[0001] The invention relates to the technical field of anti-floating anchor rod construction in building engineering, in particular to a waterproof connection structure for improving the installation stability and waterproof effect of an anti-floating anchor rod anchor plate. Background Art

[0002] In construction projects, the traditional method for anchoring basement anti-floating anchors is to lay prestressed circular anchor plates on a concrete cushion, followed by the construction of waterproofing and protective layers. However, due to the lack of an effective fixing device, these traditional anchor plates are susceptible to displacement due to horizontal stress, resulting in damage to the waterproofing layer and a significant risk of leakage.

[0003] Patent application number CN202311859702.0 discloses a waterproofing construction method for the connection between prestressed anti-floating anchor rods and raft slabs, relating to the field of waterproofing technology for anti-floating anchor rods. This method utilizes seven waterproofing measures: waterproof coating, waterproof reinforcement layer, waterproof membrane, water-swelling waterproof rubber sleeve, asphalt waterproof grease, water-swelling sealing strip, and anti-seepage concrete. These measures address various potential leakage risks associated with anti-floating anchor rods, effectively preventing water seepage at the anchor rods and improving the waterproofing quality of the basement raft slab.

[0004] Although there are some improvement schemes in the above patent technology (the combination of pads and nuts), the problem of insufficient stability of the anchor plate has not been solved, especially in terms of integrated waterproof construction and cost control. Summary of the Invention

[0005] The purpose of the present invention is to provide a waterproof connection structure for an anti-floating anchor node to solve the problems raised in the above background technology:

[0006] (1) How to solve the problem of unstable installation and poor waterproofing effect of traditional anti-floating anchor plates.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A waterproof connection structure for an anti-floating anchor node;

[0009] It includes anti-floating anchor rods, waterproof connection components, polymer cement waterproof mortar layer and fine stone concrete protective layer;

[0010] The lower end of the anti-floating anchor rod extends into the concrete anchor body of the building basement structure layer, and a concrete cushion layer is poured beside the concrete anchor body of the building basement structure layer;

[0011] The waterproof connection assembly includes an anchor plate and an embedded bracket. A through hole is opened at the center of the anchor plate. The anti-floating anchor rod extending from the upper side of the concrete anchor body passes through the through hole of the anchor plate. The embedded bracket is a frame structure. The embedded bracket is wrapped around the outer side of the anchor plate. The lower end of the embedded bracket extends into the concrete anchor body of the basement structure layer of the building.

[0012] The polymer cement waterproof mortar layer and the fine stone concrete protective layer are laid in sequence on the upper side of the concrete anchor body of the basement structure layer of the building, and the polymer cement waterproof mortar layer and the fine stone concrete protective layer completely cover the waterproof connection components.

[0013] On the basis of the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, a polymer cement waterproof mortar layer, a self-adhesive polymer modified asphalt waterproof membrane, a base plate waterproof layer and a fine stone concrete protective layer are sequentially laid on the upper side of the concrete cushion layer.

[0015] Furthermore, the upper end surface of the concrete anchor body of the basement structure layer of the building is higher than the upper end surface of the concrete cushion layer, and the concrete cushion layer and the concrete anchor body are sealed by a sealing paste.

[0016] Furthermore, the embedded bracket includes six horizontal bars and several longitudinal bars. The six horizontal bars are evenly divided into two groups. The two groups of horizontal bars are distributed up and down. The anchor plate is located between the two groups of horizontal bars. The three horizontal bars in the same group are connected in sequence to form a closed triangular frame. The two groups of horizontal bars form a triangular frame that is fixedly connected by several longitudinal bars. The lower ends of the several longitudinal bars are respectively extended into the concrete anchor body of the basement structure layer of the building.

[0017] Furthermore, the lower end of the longitudinal rod is provided with a bend that bends in the radial direction of the anti-floating anchor rod.

[0018] Furthermore, the waterproof connection assembly also includes two self-locking nut anchors, which are respectively cooperated with the anti-floating anchor rods. The two self-locking nut anchors are located on the upper and lower sides of the anchor plate, and the two self-locking nut anchors are respectively against the upper and lower end surfaces of the anchor plate.

[0019] The waterproof connection structure of this anti-floating anchor node solves the technical problems of discontinuous waterproofing and easy leakage of traditional anti-floating anchor nodes through structural innovation and material coordination. It has high reliability, convenient construction and economy, and is suitable for complex underground engineering environments.

[0020] Compared with the existing technology, the waterproof connection structure of this anti-floating anchor node has the following significant advantages:

[0021] (1) Multi-layer coordinated protection: a four-layer waterproof barrier is formed by sealing paste (filling the gap between the concrete cushion layer and the anchor body), polymer cement waterproof mortar layer (covering the anchor plate and bracket), self-adhesive waterproof membrane (full paving with continuous overlap) and fine stone concrete protective layer (mechanical protection), which completely blocks the water seepage path and reduces the leakage risk by 100%.

[0022] (2) The structural stability is enhanced. The triangular frame welded structure composed of six horizontal bars and three vertical bars of the embedded bracket disperses the stress on the anchor plate, improves the ability to resist horizontal displacement, and avoids deformation or displacement of traditional anchor plates caused by stress concentration.

[0023] (3) The embedded depth of the longitudinal rod is optimized, and the lower end of the longitudinal rod is embedded in the concrete anchor body ≥300mm to ensure the rigid connection between the bracket and the main structure, and the horizontal deviation of the anchor plate installation is ≤3mm.

[0024] (4) Construction efficiency and cost optimization, standardized module installation: embedded brackets are prefabricated in the factory and assembled on site, which shortens the construction period by 30% and reduces labor costs by 20%.

[0025] (5) The materials are highly compatible, and the sealant is highly compatible with the waterproof membrane. Seamless bonding can be achieved without special treatment, reducing the rework rate.

[0026] (6) Long-term durability is improved. Annular reinforcement ribs are installed around the anchor plate through-holes to prevent cracking at the edges of the steel plate. Steel mesh is installed within the fine stone concrete protective layer to improve crack resistance. The fully enclosed waterproof structure avoids subsequent leakage repairs and reduces overall maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

The concrete cushion layer 400 and the concrete anchor body 300 are sealed with a sealant (not shown).

[0044] The waterproof connection assembly includes an anchor plate 210 and an embedded bracket 220 . A through hole 211 is opened at the center of the anchor plate 210 , and the anti-floating anchor rod 100 extending from the upper side of the concrete anchor body 300 passes through the through hole 211 of the anchor plate 210 .
