Jinchang expansion joint factory direct Hebei Hengshui bridge expansion joint military factory was established in 1995, it is located in Hengshui City, Hebei Province. It is a collection development, design, production and sales of expansion joint manufacturers. Construction joints steps: 1, will require the construction unit joints hoisting, check whether the center line coincides with the beam centerline seam, the top surface and the road surface elevation is consistent, timely adjustments. The anchors embedded steel and welding joints firmly, and then across the 12 or 16 level bars. Expansion joints must be dismantled immediately positioning plate, engraved to locate the screw, and rubbed off the wheel burr horn, make up paint. Sealed with adhesive tape or wood joints the top slot in the notch portion 50 of the pouring of concrete; with the plug-in vibrator, vibrator fully dense. Smooth over the surface of the concrete section. Check the top surface with a ruler joints, excessive segment, should be smooth and the road. Only well after the opening of the concrete health. With anti-wall, sidewalk construction joints, the Senate made the mounting process operation. Jinchang expansion joint factory outlets 2, before installation [2] shall check whether the expansion joints with a factory certificate, manual, etc., and invite supervision, design and appearance of the officer on the joints, geometric precision inspection and acceptance, after passing before use. Scribed on the bridge, cutting: according to the location of the release of the expansion joint design center line, according to the design dimensions measured from the centerline position joints with concrete protection sideline, concrete cutting sewing machine according to the draw bridge asphalt concrete cutting edges. To ensure the trimming is not damaged, it can be divided into two cuts. The first slit edges aside from the protection zone 5cm, pending before pouring concrete, and then along a second cutting edges accurately. Slit requirements straight, accurate, careful not to damage the bridge deck waterproofing layer to protect the waterproof layer roll when cut. 3, be sure to promptly clean up the deck, filling the gap: artificial air compressor to clear cutting of asphalt concrete within the range, and chiseled loose concrete, and will clean up debris inside seam. Aperture width must meet the design requirements, after cleaning up the joints with benzene board blocking strict. Recovery embedded Anchorage, reserved number of bars to be consistent with the design drawings, not according to timely repair welding. Air compressor to clean up again. To prevent solder joints during installation flower burn foam board, foam board can be covered and protected on both sides with steel or iron. Jinchang joints when factory outlets 4. When you want to install expansion joints in place with a crane lifting, you should check good crane hook, to prevent decoupling, should be in strict accordance with the manufacturer reserved hoisting crane lifting bits, and in accordance with design drawings tie rolled steel. In the fixed process used method of controlling the cable straight along the middle and degree of telescopic device, with a length greater than 3m beam or aluminum alloy steel having sufficient rigidity to control the ride height on both sides of the expansion joints. I-beam in the vertical direction at 1m spacing joints placed and pressed on both sides of the road with the seam, the joints with a wedge-shaped steel pad level, and then use the 3m ruler wicket stand with homemade piecewise precise leveling, adjusting level process should be made of steel wedges. After the expansion joints in place, it should be adjusted to the center line and elevation joints, according to the actual road surface elevation level on both sides of the seam is determined 5m range.
