Embodiment Construction

[0032] Attached to the following Figure 1-6 This application will be described in further detail.

[0033] The embodiment of the present application discloses a frame beam prestressing reinforcement device and a construction method thereof. refer to Figure 1-3 As shown, the frame beam prestressing reinforcement device and the construction method thereof include two groups of support blocks 11 installed on the bottom surface of the frame beam along the length direction of the frame beam, and the two groups of support blocks 11 are oppositely arranged, and the support blocks 11 are blocks in the shape of a rectangular parallelepiped. structure. Both the front and rear sides of the support block 11 are welded with a support straight plate 12 , and the support straight plate 12 is provided with two sets of bolt through holes 13 penetrating the upper and lower sides of the support straight plate 12 along the length direction of the frame beam, and each set of bolt through holes...

Abstract

The invention relates to the technical field of frame beams, and discloses a frame beam prestress reinforcing device and a construction method thereof.The frame beam prestress reinforcing device comprises a plurality of sets of supporting square blocks fixed to the bottom face of a frame beam, a plurality of steel wire pull ropes penetrating through the supporting square blocks and a screwing mechanism arranged on the bottom face of the frame beam and used for screwing the steel wire pull ropes into a twisted shape; the screwing mechanism comprises a locking square column fixed to the bottom face of the frame beam and a spiral cylinder arranged on the bottom face of the frame beam in a sliding mode, the locking square column is provided with a spiral through hole, the spiral cylinder is located on the peripheral face of the spiral cylinder and is provided with spiral lines in a surrounding mode, and the spiral cylinder is in spiral fit with the locking square column. A power mechanism used for driving the spiral cylinder to rotate in the locking square column is arranged on the bottom face of the frame beam. The steel strand has the effect that the effect that the reinforcing effect cannot be achieved gradually when the gravity and the pulling force of the steel strand are not tightened gradually is improved.

Description

technical field [0001] The invention relates to the technical field of frame beams, in particular to a frame beam prestressing reinforcement device and a construction method thereof. Background technique [0002] Prestress is to avoid the premature appearance of cracks in reinforced concrete structures, and to make full use of high-strength steel bars and high-strength concrete. surface loads and sufficient mid-span flexural capacity of the slab. The commonly used reinforcement methods in the prior art include the bonding carbon fiber reinforcement method, the bonding steel plate reinforcement method, and the enlarged section method. [0003] For example, the Chinese utility model patent with the authorization announcement number CN209145324U discloses a large-span cast-in-situ slab with an external prestressed reinforcement structure, including a cast-in-place slab body and a prestressed reinforcement mechanism arranged on the surface of the poured slab body. The prestress...
