[0020] Please refer to Figure 1 The present utility model provides a technical solution: A bottom reinforcement keel for a scaffolding beam, including a reinforcing crossbar beam 110 and a half fastener 120. Half fasteners 120 are symmetrically and fixedly welded at both ends of the reinforcing crossbar beam 110. Reinforcing vertical bar beams 130 are symmetrically and fixedly installed at the outer bottom ends of the reinforcing crossbar beam 110. A radian crossbeam 140 is fixedly installed at the common bottom ends of the two reinforcing vertical bar beams 130. Both ends of the radian crossbeam 140 are fixedly connected to the bottom ends of both ends of the outer side of the reinforcing crossbar beam 110. The reinforcing crossbar beam 110 and the radian crossbeam 140 are both steel pipes with a size of 48×3.0 mm, and the reinforcing vertical bar beam 130 is a steel pipe with a size of 38×2.5 mm. A plurality of weight-reducing holes are provided on the reinforcing crossbar beam 110 and the radian crossbeam 140.

[0021] In some specific implementation manners, the above fixed connection methods can all be welding fixation, and both ends of the two reinforcing vertical bar beams 130 are respectively arranged at the centers of the reinforcing crossbar beam 110 and the radian crossbeam 140, which improves the supporting force at the center of the reinforcing crossbar beam 110, thereby improving the overall bearing capacity of the reinforcing crossbar beam 110.

[0022] In some specific implementation manners, reinforcing blocks 131 are symmetrically and fixedly installed at both outer ends of the reinforcing vertical bar beam 130. The reinforcing blocks 131 at both ends are respectively fixedly connected to the reinforcing crossbar beam 110 and the radian crossbeam 140. One side of the reinforcing block 131 is inclined. The arrangement of the reinforcing block 131 improves the stability and supportability of the reinforcing vertical bar beam 130.

[0023] Please refer to Figure 2 and Figure 3 A support rod 150 is clamped between the two reinforcing vertical bar beams 130. A level gauge 151 is fixedly installed on one side of the support rod 150. The level gauge 151 is arranged parallel to the reinforcing crossbar beam 110.

When the clamping block 154 is in contact with the limit ring 155, the level gauge 151 is parallel to the reinforcing cross beam 110, facilitating the limitation of the support rod 150 and improving the accuracy during detection.

[0026] Working principle: During use, the reinforcing cross beam 110 is fixedly installed on the scaffold through the half fastener 120.
