Abstract

The invention discloses a large-span concrete beam retard-bonded prestressed construction method, and relates to the technical field of constructional engineering. The large-span concrete beam retard-bonded prestressed construction method aims to solve the problem that the large-span prestressed construction cost is greatly improved due to the fact that required prestressed tendons are mostly purchased directly during existing large-span prestressed construction. The method comprises the steps of 1, burying prestressed steel strands; 2, checking a component; step 3, manufacturing prestressed tendons; step 4, penetrating prestressed tendons; step 5, inspecting an anchorage device; step 6, installing the anchorage device, and pre-detecting tensioning equipment; step 7, tensioning; step 8, duct grouting; and step 9, plugging an anchor head.

Description

Technical field[0001]The present invention relates to the field of construction engineering, in particular, a large span concrete beam to slow bonding prestressing construction method.Background technique[0002]Construction project refers to engineering entities formed by the construction of various housing buildings and their accessory facilities and its installation activities of their supporting lines, pipelines, and equipment. Among them, "Housing Buildings" refers to the top cover, beam column, wall, foundation, and engineering that can form internal space, meet people's production, residence, learning, and public activities. Prestressed projects are before the project structure component is loaded. The steel bars in the zipper block are applied, and the pre-stress, improve the stiffness of the member, and the time to delay the occurrence of cracks, and increase the durability of the member. For mechanical structures, it is implicitly produced in advance, which is the advantage ...
