Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a construction joint seepage prevention and water-stopping structure. Background Technology

[0002] When installing larger aluminum alloy doors and windows, elevator transportation is not feasible. Hoisting is required to transport the aluminum alloy doors and windows to the designated floors. During hoisting, suction cups are often used to adhere to the glass surface, and lifting equipment is used for high-rise hoisting. However, this method of hoisting can result in a small fixed surface area for the doors and windows. Moreover, the weight of the doors and windows during hoisting can affect the stability of the aluminum alloy doors and windows during transportation due to the heavy weight. Because the fixed area of ​​the door and window surface is small, it is not possible to effectively pull the doors and windows, which poses a high degree of danger. Utility Model Content

The inner side of the pre-embedded steel plate waterstop has an arc-shaped groove. A rubber waterstop strip is fixed above the arc-shaped groove. A water-swellable waterstop strip is installed below the rubber waterstop strip of the pre-embedded steel plate waterstop. An adhesive layer is fixed at the bottom of the water-swellable waterstop strip, and a sealing filler layer is provided above the water-swellable waterstop strip. A balance strip is fixed on one side of the pre-embedded steel plate waterstop. An installation groove is opened on the inner side of the balance strip, and an anchoring steel bar is passed through the bottom of the installation groove.

[0005] Preferably, an inner layer is fixedly provided on the inner side of the sealing filler layer, and two sets of symmetrical sliding strips are fixedly provided on the inner side of the inner layer.

[0006] Preferably, the water-swellable waterstop strip is installed below the rubber waterstop strip and is bonded to the concrete surface through an adhesive layer, with the water-swellable waterstop strip and the rubber waterstop strip stacked one on top of the other.

[0007] Preferably, the sealing filler layer is filled on top of the construction joint, covering the water-swellable waterstop strip and the rubber waterstop strip, and the sealing filler layer is composed of polysulfide sealant.

[0008] Preferably, the anchoring bars are distributed at equal intervals on both sides of the pre-embedded steel plate waterstop, and the anchoring bars are welded and fixed to the external concrete structure.

[0010] Preferably, a connecting strip is fixedly provided above the rubber waterstop strip, and a cover plate is fastened and connected above the sealing filler layer. The cover plate is made of stainless steel, and a drainage blind pipe is provided at the bottom of the construction joint.

[0011] (1) By setting up a combination structure of pre-embedded steel plate waterstop, rubber waterstop, and water-swellable waterstop, multiple waterstop defense lines are formed, which significantly improves the waterproof performance of construction joints. By using anchor steel bars that are evenly distributed, the waterstop is firmly connected to the concrete structure, avoiding displacement or falling off during construction and improving installation stability.

[0012] (2) By setting a sealing filler layer and a stainless steel cover plate, the upper part of the construction joint is effectively sealed to prevent external rainwater or groundwater from directly infiltrating, while also having good weather resistance and aesthetics.
