Embedded rubber water stop band with transverse built-in reinforcing ribs

Abstract

The invention discloses an embedded rubber water stop band with transverse built-in reinforcing ribs. The embedded rubber water stop band comprises a water stop band body, wherein clamp heads are respectively arranged at the two side edges of the water stop band body along the width direction of the water stop band body; a plurality of reinforcing plates are arranged in the water stop band body atintervals along the length direction of the water stop band body; a certain distance is formed between any two adjacent reinforcing plates; each reinforcing plate extends along the width direction ofthe water stop band body. The embedded rubber water stop band has the advantages that by arranging the reinforcing plates in the water stop band body along the length direction of the water stop band, the transverse support is provided for the water stop band; in the construction process, especially in the concrete pouring process, the rubber water stop band still can maintain the horizontal state without the outside support device, the anchoring ability and waterproof ability of the rubber water stop band are enhanced, and the construction time for additional arrangement of the water stop band support device is shortened.

Description

technical field [0001] The invention relates to the technical field of waterstops used in civil engineering, in particular to a laterally built-in reinforcement type mid-buried rubber waterstop. Background technique [0002] The mid-buried waterstop is an important waterproof material for the concrete joints in the tunnel. It is installed in the middle of the second lining of the tunnel. It can deform with the displacement of the tunnel deformation joint without losing the waterstop function. Using its waterstop and soft characteristics, the Water is intercepted beyond the second lining. [0003] The current waterstops have low transverse stiffness and are easy to bend. The construction quality of the waterstop is also an important part of tunnel waterproofing. At present, during the construction of the waterstop, one side of the waterstop is erected, the other side is suspended, and the "end" of the waterstop is flat with steel clips. It ensures that the waterstop will no...

Problems solved by technology

[0003] The current waterstop is less rigid in the lateral direction and is easy to bend

The construction quality of the waterstop is also an important part of tunnel waterproofing. At present, during the construction of the waterstop, one side of the waterstop is erected, the other side is suspended, and the "end" of the waterstop is flat with steel clips. It ensures that the waterstop will not sag or deform during construction, but it increases the construction time, delays the construction progress, and virtually increases the construction cost, and the waterstop is in direct contact with the steel bar, which causes the gap between the waterstop and the steel bar It is difficult to compact the concrete between the waterstop and the steel bar, and the concrete between the waterstop and the steel bar is also prone to cracks and pores during the process of marking, which affects the construction quality and increases the hidden danger of water leakage

Remove the steel clips, the waterstop will easily sag and deform due to its own gravity, and in the process of pouring concrete, the waterstop will also shift due to the impact, flow and vibration of the concrete. In this way, it cannot be guaranteed that the anchor end of the waterstop can be fully anchored in the concrete, causing the waterstop to fail to fully exert its waterproof function

Since there is no adhesive force between the rubber of the waterstop and the concrete, the concrete at the joint will become thinner after the waterstop is shifted, causing the phenomenon of "dropping blocks", which seriously affects driving safety

[0004] When the waterstop is produced and vulcanized, in order to ensure the appearance quality of the waterstop and prevent rubber shortage, the sum of the upper and lower semi-finished films between the molds is greater than the thickness of the mold cavity, and the rubber is in a fluid state when it is pressurized and heated. The rubber needs to flow out from the delivery end of the mold, and at the same time it will drive the reinforcement plate to change its original position, resulting in too large spacing between the reinforcement plates and unqualified products
