The invention provides an arc-shaped roof prestressed reinforcement arrangement system and a construction method thereof. The arc-shaped roof prestressed reinforcement arrangement system comprises anupper arc-shaped prestressed reinforcement layer and a lower arc-shaped prestressed reinforcement layer, wherein the upper arc-shaped prestressed reinforcement layer is located below the upper non-prestressed reinforcement layer; the lower arc-shaped prestressed reinforcement layer is located above the lower non-prestressed reinforcement layer; each arc-shaped prestressed reinforcement layer comprises prestressed reinforcements which are uniformly arranged at intervals; the prestressed reinforcements comprise slow-bonding prestressed reinforcements; each prestressed reinforcement comprises a tensioning end, a fixing end and a steel strand connected to the tensioning end; each tensioning end comprises a spiral reinforcement I, a small bearing plate, a clamping piece anchor and a cavity diewhich are sequentially arranged; and each fixing end comprises a spiral reinforcement II, a single-hole bearing plate and an extrusion anchor which are sequentially arranged. According to the arc-shaped roof prestressed reinforcement arrangement system, the slow-bonding prestressed reinforcements are independently arranged in an arc-shaped roof and are effectively bonded with the full-length rangeof concrete, so that when holes need to be formed due to function change in the use stage, the prestressed steel strands can be flexibly cut off, and the arc-shaped roof prestressed reinforcement arrangement system has obvious technical advantages compared with non-bonded and bonded prestressed reinforcements.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a system for laying prestressed steel bars on a curved roof and a construction method thereof. Background technique [0002] Prestressed steel bars can effectively reduce the temperature cracks caused by large spans because they can bring better tensile or compressive resistance when used, so they are popularized in the construction industry. However, most of the existing prestressed steel bars are unbonded prestressed steel strands, which are clad on the basis of bonded steel strands, and do not directly contact with concrete soil, which is convenient for tensioning and gripping with concrete. Insufficient binding force, it is easy to loosen during use, which affects the performance. Bonded prestressed steel strands mean that the steel strands are in direct contact with the concrete. There is no outsourcing plastic tube, and the binding force with the concrete is strong, but...
