Abstract

The utility model discloses a prestress large span portal steel frame which comprises an H-shaped steel beam and steel stand columns. Two ends of the steel beam are fixedly arranged at the upper ends of the steel stand columns to form a shape of a portal. The H-shaped steel beam comprises a plurality of sections of prestress H-shaped beams. A flange is arranged at the end of each section of the prestress H-shaped beam. A full prestress tendon which is communicated through the whole span is arranged along the horizontal direction of the side face of the H-shaped beam. Prestress tendons are arranged along the vertical direction close to the outside of the upper portions of the steel stand columns. The full prestress tendon and the prestress tendons are respectively fixed on the H-shaped steel beam and the steel stand columns through high-strength bolts. The prestress large span portal steel frame can satisfy the requirements of a large span and big column spacing and save steel materials, and construction is simple.

Description

The prestressed large-span portal frame
Technical field
The utility model belongs to the prestressed steel structure building field, especially a kind of prestressed large-span portal frame.
Background technology
Mostly with the H type i-beam frame of welding, steelframe and steel column all adopt variable cross-section to existing large span portal frame, to reduce own wt; Save steel, but span has just caused unreasonable structure when strengthening easily; Steel material increases severely; Can't satisfy growing market to large span, the huge pillar distance, low with steel requirement.
Summary of the invention
The present invention is directed to the deficiency of prior art, proposed a kind of prestressed large-span portal frame.
The prestressed large-span portal frame is made up of H section steel beam and steel post; The upper end that the girder steel two ends are installed in two steel posts is a shape; Described H section steel beam is made up of several sections prestressing force H section steel beams, and its every section prestressing force H section steel beam end is provided with flange, and H section steel beam side horizontal direction is provided with the elongated presstressed reinforcing steel that perforation is striden entirely; Steel post top biased outward vertical direction is provided with presstressed reinforcing steel, elongated presstressed reinforcing steel WithPresstressed reinforcing steel all is separately fixed on H section steel beam and the steel post through high-strength bolt.
The beneficial effect of the utility model: the utility model can satisfy large span, the requirement of huge pillar distance, and save steel, construction is simple.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The prestressed large-span portal frame is made up of H section steel beam 1 and steel post 2, and the upper end that the girder steel two ends are installed in two steel posts 2 is a shape, and described H section steel beam 1 is made up of several sections prestressing force H section steel beams; Its every section prestressing force H section steel beam end is provided with flange 3; H section steel beam 1 side horizontal direction is provided with the elongated presstressed reinforcing steel 4 that perforation is striden entirely, and steel post 2 top biased outward vertical direction are provided with presstressed reinforcing steel 5, elongated presstressed reinforcing steel 4 WithPresstressed reinforcing steel 5 all is separately fixed on H section steel beam and the steel post through high-strength bolt.
