Embodiment Construction

[0008] Such as figure 1 As shown, the present invention is a new and old concrete structure splicing device in a renovation project, which includes a group of anchoring devices, the device consists of an anchoring steel plate 1, a plywood 2, a rib plate 3, a bolt 4, a rubber water stop plate 5, and a grouting valve 6 When cutting the old concrete structure, a through groove is longitudinally cut in the middle of the structure, and the rubber water stop plate 5 is installed in the through groove; the anchor steel plate is attached to the cutting surface of the old concrete structure 9, and the water-swelling The rubber plate and the bolts are fastened and sealed; after tightening, the splint will clamp the rubber water-stop plate, so that a closed sealed cavity is formed between the old concrete structure and the rubber water-stop plate; the lower grouting valve connects the grouting pump and the grouting pipe , the upper exhaust valve is fully opened; when grouting, the middle...

Abstract

The invention relates to reconstruction engineering, in particular to assembling of a new concrete connector and a used concrete connector in reconstruction engineering. An anchoring clamping device is manufactured in sections according to the specifications of a used concrete structure; the used concrete structure and a rubber water stop plate mounting groove are cut; the anchoring clamping device is mounted; bolts are fastened; expansion cement paste is injected into an upper injection valve and a lower injection valve in a balanced mode, and the pressure is maintained for initial setting; injection pipes are dismantled, and the anchoring clamping device is dismantled after the expansion cement paste is totally solidified; and structure steel bars are welded, and a new concrete structure is constructed. Operation is convenient, a large quality of labor costs and material costs are saved, and meanwhile generation and discharging of building garbage are reduced.

Description

technical field [0001] The invention relates to a renovation project, in particular to the assembly of new and old concrete joints in the renovation project. Background technique [0002] When carrying out engineering transformation in the built-up area, the existing concrete structure of the transformed site must be chiseled out, but there are some situations where the buried depth, specification and strength of the existing concrete structure are similar to those of the reconstructed new concrete structure. If this part of the existing old concrete structure Making full use of it and splicing it with the new concrete structure will save a lot of manpower and material resources, and will also reduce the generation and discharge of construction waste. Most of the common new and old concrete structures are assembled with interface agent, which is not suitable for load-bearing structures. Contents of the invention [0003] The invention aims to overcome the defects of the p...
