What is the role of steel edge sealing?

The steel edge waterstop is a composite of retractable rubber and galvanized steel strips. The steel edge sealing tape is mainly compressed or stretched between the deformation joints of the concrete by the middle rubber section, and acts as a sealing and sealing effect.

In general, the adhesion of concrete and rubber is poor. In conventional construction, because the rubber is a soft elastomer, the concrete is not easily compacted during pouring, so when the concrete seam expands, pulls away, and twists, it will The rubber water stoppages often appear loose and fall off, resulting in leakage at higher head pressures.

For joints with large deformation joints, it is more prominent. The use of galvanized steel band rubber combined waterstops can basically overcome these deficiencies of pure rubber bridge waterstops. In addition, this combined type water-stopping belt also has a dual function: on the one hand, it can extend the way and delay the speed of water seepage; on the other hand, the galvanized steel belt and the concrete have good adhesion, so that the water stop belt can withstand greater pulling force. And torsion force, so as to ensure that there will be no loosening and shedding phenomenon in the effective deformation range of the concrete in the rubber water stop zone and improve the water stop effect.

The steel-edge rubber waterstops are semi-finished materials, which are likely to cause quality ignorance due to construction and lead to quality risks. Attention should be paid to various technical indexes during construction. Quality department inspections must be strictly performed in accordance with the standards; rubber waterstops are prone to ageing in the open air. The parts are prone to ageing, and the tensile strength after aging is greatly reduced. Therefore, it is necessary to pay attention to the protection of the naked-leakage part; pay attention to the scientific and rational treatment of deformation joints at the rubber water-stop belt; the rubber seal of the back-adhesion type should be hardly protected; The hose should not be used for large deformation projects. If leakage occurs, grouting can be done effectively and quickly. The waterproof quality is reliable and does not recur. Its comprehensive cost is the most economical and completely solves the weaknesses of traditional water stoppages.

Steel-edge rubber sealing has its advantages and weaknesses. It is particularly important how to select rubber sealing tapes for construction joints and deformation joints in waterproof construction and how to construct them. The construction unit must not decide on its own choice, otherwise it will result in engineering quality and structural safety. Immeasurable loss, this is the result of any construction management personnel and construction units do not want to see, so familiar with the performance of rubber water stop, pay attention to the installation and use requirements of rubber water stop is the prerequisite for the selection of rubber water stop .
