[0022] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0023] In order to solve the problems of long construction period, high cost and serious waste in the demolition and modification of concrete structure foundation by traditional technology, this embodiment provides a reinforcement component suitable for concrete foundation beam, including Figure 1 , 2 The two rows of beam top bearing flat steels 1 and 2 are used to fix the two sides of the beam top of the foundation beam 0 in the horizontal direction. Figure 3 , 4 The flat steel hoops shown are composed of two rows of bottom beam flat steels 2 fixed on the two horizontal sides of the bottom of the foundation beam 0; also include a plurality of transverse gusset plates 3 evenly arranged along the longitudinal direction of the foundation beam 0 for fixing between the two rows of top beam stress flat steels 1 or the two rows of bottom beam flat steels 2; and the bottom beam stress angle steel 4 shown in 5 for welding outside the bottom beam flat steel 2, one side of which is located on the beam wall in the vertical direction of the foundation beam 0.

[0024] Depend on Figure 1 or Figure 2 It can be seen that it also includes a steel hoop 6 for fixing to the top of the frame column 5, and Figure 3 or Figure 4 The flat steel hoop 7 fixed to the outside of the bottom of the frame column 5 is used to reinforce the frame column. Figure 2 The steel hoop 6 shown in the figure and the beam top load-bearing flat steel 1 or Figure 4 The flat steel hoop 7 and the load-bearing angle steel 4 at the bottom of the beam are respectively welded with equal-generation inclined flat steels 8 to achieve rigid support for the reinforcement of the frame column and the reinforcement flat steel assembly of the foundation beam 0, thereby completing the overall reinforcement.

[0025] Also includes multiple Figure 5 The vertical tie plates 9 are evenly arranged along the longitudinal direction of the foundation beam 0, and the lower end of the vertical tie plates 9 is welded to the load-bearing angle steel 4 at the bottom of the beam, and the upper end of the vertical tie plates 9 is connected to the lower end of the screw end bar steel hoop 10; the screw section of the screw end bar steel hoop 10 passes upward through the foundation beam 0 and the load-bearing flat steel 1 at the top of the beam and is fastened by a nut. Figure 5 It is clearly visible that an angle steel 11 is provided between the frame column 5 column angle and the steel hoop 6, and the angle steel 11 and the steel hoop 6 are fixed to the frame column 5 in sequence by chemical bolts 12. The angle steel 11 realizes the rigid connection and support of the beam top load-bearing flat steel 1 and the steel hoop 6.

[0026] In specific implementation, the foundation beam 0 and the steel hoop 6 or flat steel hoop 7 need to be connected by adhesive steel glue, and the gap between the beam bottom stress angle steel 4 and the foundation beam 0 needs to be filled with epoxy resin after the fixed connection with other components is completed. That is, the gaps between the adjacent horizontal tie plates 3, the vertical tie plates 9 and the gaps between them and the foundation beam are filled with epoxy resin. The gap between the steel hoop 6 and the frame column 5 is also filled with epoxy resin. Finally, a concrete layer needs to be poured outside the steel hoop 6.

[0027] It should also be noted that, in order to enhance rigid protection, the beam top load-bearing flat steel 1 is fixed to the foundation beam 0 by bolts.

[0028] Finally, with the help of Figure 6 and Figure 7 It can be seen that the vertical tie plate 9 between the screw end rod steel hoop 10 and the foundation beam, the gap between the vertical tie plate 9 and the foundation beam is provided with a steel pad 13. Figure 7 It can be seen that the angle steel, i.e. the beam top stress angle steel 14, is wrapped outside the side beam and fixedly connected to the corresponding beam bottom stress angle steel 4 through the vertical tie plate 9 here. The transverse tie plate 3 set between the beam top stress flat steel 1 and the cutout of the beam top stress flat steel 1 can be flat-welded to achieve the flatness of the surface layer.

[0029] In summary, it is not difficult to see that the reinforcement components suitable for concrete foundation beams provided in the above embodiments have simple structures, small numbers of components, are easy to implement, have short construction periods, low costs, are highly efficient and practical, and can effectively protect the foundation beams of existing subway vehicle depots.
