The scaffold 4 is provided in the lateral direction, and each support frame 3 below is connected, the scaffold 4 is erected on each support frame 3, and a constructor builds a capping beam on the scaffold 4.

The bearing groove 101 of the bridge pier 1 realizes the vertical support of the bracket 2 through the support of the supporting leg 203, and then the bracket 2 vertically supports the scaffold bracket 4 above through the supporting frame 3. Each bracket 2 is connected with the scaffold bracket 4 through the support frame 3, so that the scaffold bracket 4 forms radial limit to each bracket 2, each bracket 2 can be stably attached to the bridge pier 1, the support legs 203 are kept in plug connection with the bearing grooves 101, the bridge pier 1 stably vertically supports the bracket 2, and the stability of a support system is improved.

In the above-mentioned exemplary embodiment, the bracket of the multi-column capping beam supporting system is connected with the bridge pier in an inserting manner, so that the bridge pier directly supports the bracket in the vertical direction, the bracket has stronger bearing capacity, the scaffold bracket is also supported by the bridge pier, and the bearing capacity of the supporting system is increased; the scaffold bracket is connected with each bracket through the supporting frame, so that the brackets are kept upright and stable, the support teaching bracket is stable, and the stability of a support system is improved; the pier sets up the loading groove, has reduced its structure volume, makes the concrete quantity reduce, and when the pier set up the ox horn, need set up the reinforcing bar and extend to the ox horn in support it, the loading groove makes the pier need not to additionally set up the reinforcing bar and supports it, still makes the reinforcing bar quantity reduce for the construction progress, reduces construction cost, has solved current support system support ability not enough, increases the problem of construction degree of difficulty and material quantity.

In some embodiments, as shown in fig. 6, the bearing groove 101 is embedded with a channel steel 102, and the support leg 203 is inserted into the channel steel 102. The channel steel 102 reinforces the inner wall of the bearing groove 101, the materials are easy to obtain, the installation is simple, and the bearing groove 101 is prevented from cracking under the heavy pressure of the supporting legs 203, so that the stability of the bearing groove to the bracket support is ensured.

In some embodiments, the support frame 3 includes a middle support frame 301 and a rim support frame 302. The supporting frames 3 are arranged in the transverse direction, the supporting frames 3 between two adjacent bridge piers 1 are middle supporting frames 301, the supporting frames 3 at two ends in the transverse direction are edge supporting frames 302, namely, the two supporting frames 3 at the outermost side are edge supporting frames 302, and the supporting frame 3 at the middle is middle supporting frame 301.

The space 5 also provides an operation space for constructors, so that the construction of a supporting system and the construction of a bridge are more convenient.

In some embodiments, the bridge pier 1 has the connecting ribs 103 arranged radially, and the protruding connecting ribs 103 are embedded in the bridge pier 1, so that the construction difficulty of the bridge pier 1 is not increased. The two ends of the connecting ribs 103 are respectively connected with the corresponding brackets 2 on the two sides of the bridge pier 1, and the brackets 2 on the two sides are connected in a pulling way through the connecting ribs 103, so that the brackets 2 are kept stable in the radial direction and cling to the bridge pier, and the upper structure is kept stably supported. In addition, the bracket 2 can be independently and stably fixed on the pier 1 through the supporting legs 203 and the connecting ribs 103, and the supporting frame 3 is overlapped to the bracket 2 in the process, so that the bracket 2 is not required to be supported, and the construction of a supporting system is easier.
