Problems solved by technology
In order to disperse the excessive compressive stress at the anchorage end of prestressed steel bars, the existing temporary fastening system often needs to be equipped with additional steel pressure-bearing backing plates, which increases the cost
In order to avoid the setting of backing plates, in some applications, large and long end anchors are used to disperse the stress and ensure the stability during tension; the existing method not only uses a lot of steel, but also is heavy, inconvenient to operate, and increases manpower Cost and Energy Consumption

The invention discloses a temporary fastening connection system applicable to prefabricated large components, including large prefabricated components, the fastening connection system includes anchor beams, anchor beams located at both ends of large prefabricated components and corresponding in positions form a group, the anchor beams There are multiple groups symmetrically arranged, and each group of anchor beams is installed with prestressed tendons on the inside and outside of the large prefabricated component; Suspension studs are installed at both ends, and the suspension studs are vertically arranged with the prestressed tendons and pass through the middle of the anchor beam; after the fastening connection systems are installed on the two large prefabricated components, the two large prefabricated components are connected , the prestressed tendons are prestressed after passing through the anchor beams on the two large prefabricated components. The fastening connection system can be suspended and installed at any set height, effectively avoiding the setting of prestressed tunnels or tensioning tooth plates on the original concrete components, and can be reused with low cost.
Description
technical field [0001] The invention relates to the technical field of temporary fastening of prefabricated large components, in particular to a temporary fastening connection system applicable to prefabricated large components. Background technique [0002] In the construction, installation, and testing of civil engineering structures, it is often necessary to temporarily fasten some large prefabricated components, and tensioned prestressed steel bars are a widely used temporary fastening measure. [0003] At present, the prestressed steel bars used for temporary fastening of prefabricated large components often penetrate into the channels reserved in the prefabricated concrete components. Under the state of tension and anchorage, the precompressive stress is transmitted to the end face of the concrete component through the anchorage and its lower backing plate; Some use templates to make tooth plates during prefabrication of concrete components, and anchor prestressed stee...
