[0002] The cap beam support structure across existing roads is a commonly used support structure for beam construction on existing roads. Supports are built on both sides of the road to erect the beam to support the various loads required during the beam construction process to ensure construction safety and quality. This structure needs to be designed according to the specific site conditions, beam size and load requirements to ensure the stability and safety of the support. The traditional support structure requires the construction of a cap foundation in addition to the original cap foundation, which increases the construction volume. The strength of the additional construction foundation is different from that of the cap foundation, resulting in uncontrollable support stability. In order to ensure the strength of the support, the only option is to increase the support structure. Utility Model Content

In order to ensure the strength of the support, the only way is to increase the support structure parts.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cap beam support structure across an existing road, comprising a main beam, support columns are provided on both sides of the lower surface of the main beam, a pedestal foundation is provided at the lower end of the support column, an inclined support tube is provided at the inner end of the upper surface of the two pedestal foundations and below the main beam, two inclined support tubes are provided at the upper end of the pedestal foundation on each side, a pull rod is provided between the outer surface of the two inclined support tubes and the support column, a support beam is provided between the upper ends of the two inclined support tubes, a vertical support tube is provided at the outer end of the upper surface of the two pedestal foundations and on the outer side of the support column, four vertical support tubes are provided on the pedestal foundation on each side, a stress frame is provided between the upper ends of the four vertical support tubes, and a stress beam is provided at the upper end of the stress frame.

[0005] Preferably, a pre-buried support beam is provided at a position of the inner upper end of the pedestal foundation corresponding to the inclined support tube and the vertical support tube, and the inclined support tube and the vertical support tube are fixedly connected to the pre-buried support beam by bolts.

[0006] Preferably, a pre-buried tension beam is provided at a position on the outer surface of the support column corresponding to the pull rod, and the pull rod is fixedly connected to the pre-buried tension beam by bolts.

[0007] Preferably, pads are provided at the upper ends of the four inclined support tubes and between the support beams, and support beams are provided on the upper surfaces of the support beams.

[0008] Preferably, a reinforcing wedge is provided between the upper ends of the two support columns and the main beam.

[0009] Compared with the prior art, the beneficial effects of the utility model are: instead of the traditional support structure which needs to construct a pedestal foundation outside the original pedestal foundation, the support utilizes the pedestal foundation and does not require an additional construction foundation. It is suitable for situations with limited height requirements, can be pre-stressed by itself, does not require additional counterweights, is beneficial to safety, and ensures support strength on the basis of a simple structure.
