Combined back-pasting type water stop belt

Abstract

A combined back-pasting type water stop belt comprises a first connecting plate, a second connecting plate, convex ribs, connecting ribs, a central arc-shaped part and a hydrophilic rubber circular pipe; the first connecting plate, the second connecting plate and the central arc-shaped part are made of rubber materials; the first connecting plate and the second connecting plate are fixedly connected with two side edges of the central arc-shaped part respectively; the arc surface of the central arc-shaped part is downward; a plurality of convex ribs are arranged on the lower surfaces of the first connecting plate and the second connecting plate; the bottom of the central arc-shaped part is fixedly connected with the hydrophilic rubber circular pipe through the connecting ribs, and the hydrophilic rubber circular pipe is parallel to the central arc-shaped part; The bottom of the central arc-shaped part is connected with the hydrophilic rubber circular pipe through the connecting ribs; the central arc-shaped part has a sealing effect on a construction joint, the hydrophilic rubber circular pipe expands when meeting water and can fill the construction joint, a double-safety effect is achieved; and even if the central arc-shaped part or the connecting plate is punctured, the hydrophilic rubber circular pipe can also have a good waterproof effect.

Description

technical field [0001] The invention belongs to the technical field of water stop for building construction joints, and in particular relates to a combined back-adhesive water stop belt. Background technique [0002] Waterproofing of buildings has always been a key issue in the construction field. At present, the waterstops used in my country are mainly divided into mid-buried rubber waterstops and back-mounted rubber waterstops according to the usage conditions. The mid-buried waterstops are often separated from structures. The steel bars are disturbed, so the back-mounted waterstop (also called the outer-mounted waterstop) is widely used in tunnel waterproofing, and the rubber back-mounted waterstop has good elasticity, wear resistance, and anti-aging properties And tear resistance, strong adaptability to deformation, good waterproof performance, but there are many sharp stones and steel heads in the concrete, the waterstop is easy to be punctured or torn, and the crack will...

[0002] Waterproofing of buildings has always been a key issue in the construction field. At present, the waterstops used in my country are mainly divided into mid-buried rubber waterstops and back-mounted rubber waterstops according to the usage conditions. The mid-buried waterstops are often separated from structures. The steel bars are disturbed, so the back-mounted waterstop (also called the outer-mounted waterstop) is widely used in tunnel waterproofing, and the rubber back-mounted waterstop has good elasticity, wear resistance, and anti-aging properties And tear resistance, strong adaptability to deformation, good waterproof performance, but there are many sharp stones and steel heads in the concrete, the waterstop is easy to be punctured or torn, and the crack will expand without a lot of external force, Therefore, it is easy to damage the waterproof belt in the process of fixing the waterstop and pouring concrete; the waterstop with hydrophilic properties can form a reliable seal in the concrete joints, but the hydrophilic waterstop is very difficult in the presence of water Rapid expansion will cause the seal to fail, so after installing the hydrophilic waterstop, it is necessary to pour concrete for the second time as soon as possible to prevent rain or water in the air from reacting with the waterstop
