Example of type of steel edge rubber waterstop construction joint flat web type middle buried waterstop deformation joint middle hole type middle buried waterstop deformation joint middle hole type externally attached Waterstop Strip Edge rubber waterstop setting method plane deformation joint waterstop setting method facade deformation joint waterstop setting method example: externally attached and middle buried waterstop suspension method preset steel edge rubber waterstop joint form steel edge rubber Examples of various joints of rubber waterstop: cross joint of waterstop steel edge rubber waterstop butt joint mode of steel edge rubber waterstop butt joint can adopt two modes: field vulcanization and cold butt joint.
Several micro signals of construction are recommended for you to add by long pressing the identification QR code!..
External rubber waterstop shall be set on the upstream surface; Embedded waterstop is set in the middle of the structure.
On the other hand, the galvanized steel edge has good adhesion with the concrete, so that the waterstop can bear large tension and torsion, so as to ensure that the rubber waterstop will not loose and fall off within the effective deformation range of the concrete and improve the waterstop effect.
2.
The rubber waterstop joint shall be butt joint type instead of lap joint type.
Field vulcanized joints are preferred, and cold butt joint can be used.
Steel edge waterstop, i.e.
The process flow examples are as follows.
steel edge rubber waterstop, is composed of rubber waterstop and steel edge.
3.
The vulcanization time is determined according to the thickness of the steel edge waterstop (350) × The vulcanization time of 10mm steel edge waterstop is 30 ~ 15min) (4) after reaching the vulcanization time, disconnect the power supply, take out the mold, conduct hot vulcanization docking on site, 2 cold docking (1) place a U-shaped hoop on the steel edges at both ends of the waterstop, drill holes with a hand electric drill according to the hole spacing of the U-shaped hoop (2) drill holes outside the riveted U-shaped hoop, Wrap a circle of 2.0mm-thick unvulcanized butyl rubber putty sheet horizontally along the steel edge waterstop and bond the butyl putty sheet (3) stick a layer of 2.0mm-thick rubber sheet on the outside of the unvulcanized butyl rubber putty sheet and bond the rubber sheet.
The deformation joint must be of medium pass type; The construction joint adopts flat plate type.
Application points of steel edge rubber waterstop 1.
It is mainly used for the construction of construction joints and deformation joints of underground waterproof engineering.
The waterstop is cold connected on site.
1 hot vulcanization butt joint (1) fix the U-shaped hoop on the steel edge with rivets (2) put the required rubber into the reserved gap of the waterstop, cut the rubber size according to the reserved gap size, cover the mold, tighten the bolts, put the rubber into the reserved gap, cover the mold, tighten the bolts (3) turn on the power supply, and when the temperature display of the temperature controller reaches the specified temperature (135 ~ 160 ℃), The red light of the temperature controller is on, the power is cut off automatically, and the vulcanization time is recorded.
The steel edge rubber waterstop has dual functions.
It gives full play to the characteristics of waterstop and steel edge, with stronger waterproof and more uniform and reasonable stress.
On the one hand, it can prolong the way and delay the water seepage speed.
