4. Construction method
Install the bearing at the bottom of the beam. During installation, you should Make the symmetrical center line of the support coincide with the symmetrical center line of the beam bottom plate, and the deviation shall not be greater than the first tightening of the support bolts. The tightening degree of each bolt should be basically the same. After the bolt tightening is completed, there shall be no gap between the support and the beam support plate. gap.
. Install the anchor bolts in the anchor bolt holes of the support. The length of the bolt extending out of the nut is the diameter of the bolt. Tighten the nuts and sleeve bolts to prevent grout leakage at the joint between the sleeve bolts and the bottom surface of the support.
Mark the longitudinal and transverse symmetrical support center lines on the supporting pads. Chisel the surface of the supporting pads, remove debris left in the anchor bolt holes, and saturate the surface of the supporting pads with water, but no open water is allowed during construction. Then lay a thick layer of dry hard non-shrinkage mortar (i.e. high-strength mortar) on the top surface of the supporting pad stone and compact it to make the surface smooth. Note that the mortar elevation should take into account the compression of the mortar after the beam is dropped. Remove debris left in the anchor bolt holes, and before the beam is in place, pour super early-strength bearing grouting material into the anchor bolt holes to below the top surface of the supporting pad.
The slurry is prepared according to the weight ratio of powder to water). Water should be added into the mixing barrel first, and then the weighed grouting material should be gradually added. Stir with an electric mixing gun while adding the material, until all the powder is added, and then continue stirring for a few minutes to make the slurry uniform. The mixed slurry should be poured within minutes.
When the beam is dropped, the center line of the support should coincide with the longitudinal and transverse symmetrical center line of the support on the top of the pad. After the beam is dropped, the high-strength mortar should be cured in time.
After the grouting material of the anchor bolt holes reaches the specified strength, tighten the anchor bolts, remove the temporary connecting plate of the bearing, and install the bearing sealing enclosure plate.
