Detailed Description
The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in fig. 1, the utility model discloses the strenghthened type encloses the purlin and includes first sharp roof beam 3 and the sharp roof beam 4 of second, the one end of first sharp roof beam 3 and the one end fixed connection of the sharp roof beam 4 of second, and fixed mode can adopt welding or bolted connection, and first sharp roof beam 3 and the sharp roof beam 4 mutually perpendicular of second after connecting form the angle steel structure.
Be provided with a plurality of slant strengthening rib 2 between first sharp roof beam 3 and the second sharp roof beam 4, the both ends of slant strengthening rib 2 respectively with first sharp roof beam 3 and second sharp roof beam 4 fixed connection, be fixed with connecting rod 1 between a plurality of slant strengthening ribs 2 in proper order. The oblique reinforcing ribs 2 and the connecting rods 1 can enhance the overall strength of the enclosing purlin and prevent two linear beams forming the angle steel structure from deforming under the action of external force.
The internal structure of the first linear beam 3 and the second linear beam 4 is the same. Taking the first linear beam 3 as an example, as shown in fig. 2, the first linear beam 3 includes a left steel plate 6 and a right steel plate 6, three i-beams 7 are arranged between the two steel plates 6 at equal intervals, the three i-beams 7 are vertically arranged, and 56 i-beams 7 are selected as the i-beams 7. A plurality of inner reinforcing ribs 10 are arranged in the web plate among the three I-shaped steels 7 along the radial direction, and all the inner reinforcing ribs 10 are parallel to each other. Longitudinal reinforcing ribs 8 are respectively welded on the web plates on the outer sides of the two I-shaped steels 7 positioned on the edges, the longitudinal reinforcing ribs 8 are respectively connected with the web plates of the two steel plates 6 and the I-shaped steels 7, and all the longitudinal reinforcing ribs 8 are parallel to each other. The middle part of the longitudinal reinforcing rib 8 is provided with a transverse reinforcing rib 9, and the transverse reinforcing rib 9 is respectively connected with the I-shaped steel 7 and the longitudinal reinforcing rib 8.
The end faces of the free ends of the first linear beam 3 and the second linear beam 4 which are not connected are provided with baffles, and connecting plates 5 are fixed on the baffles. As shown in fig. 3 and 4, the connecting plates 5 are divided into two structures, namely a male head 11 and a female head 13, and one of the connecting plates 5 on the first linear beam 3 and the second linear beam 4 is the male head 11, and the other is the female head 13. Male head 11 and female head 13 can be pegged graft the installation, and corresponding position all processes pinhole 12 on male head 11 and the female head 13 for the installation locating pin.
