Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to an assembleable inclined tower limb beam bracket. Background Art

[0002] In bridge construction design, cable-stayed bridges are widely used by designers due to their beautiful appearance and large span. The lower limb of the cable-stayed bridge tower is tilted outward, and the upper limb is tilted inward. The lower crossbeam is set at the intersection of the broken line of the lower and upper limbs. During the construction of the crossbeam of a large-span cable-stayed bridge, since the tower columns are generally large in height and the crossbeam position is generally more than 60m, it is impossible to directly install steel pipe piles on the lower part of the crossbeam to support the cast-in-place bracket. For this reason, it is necessary to install shear members in the pre-buried space on the inner side of the tower limb, and install the tower limb crossbeam bracket through the installed shear members. In this way, during the construction of the lower crossbeam, the load is transferred to the tower limbs on both sides through the installed shear members and the constructed bracket, thereby providing conditions for the safe construction of the lower crossbeam.

[0003] Prior art discloses support structures for lower crossbeams of cable-stayed bridges. For example, CN206859068U discloses an assembled support frame structure for lower crossbeams of cable-stayed bridge towers. The structure comprises a bottom formwork system for casting the lower crossbeams and a support system supported below the bottom formwork system and arranged transversely to the bridge. The structure also comprises two sets of triangular trusses spaced transversely and fixed to the tower limbs on either side via lower supports. Horizontal straight beams arranged transversely to the bridge are mounted on the two sets of triangular trusses. The ends of the straight beams are fixedly connected to the tower limbs on either side via upper supports. The straight beams are located below the support system and are fixedly connected to the support system. The lower support is a connector with one end pre-embedded in the tower limb and the other end extending transversely to the outside of the tower limb. The lower end of the triangular truss is fixed to the portion of the connector extending outside the tower limb. The assembled support frame structure for lower crossbeams of cable-stayed bridge towers disclosed in this patent is easy to install, reduces the workload of aerial welding, and is simple to construct and operate. It is undeniable that the support frame structure disclosed in this patent can indeed achieve the above-mentioned effects, but it still has certain shortcomings: since the triangular truss is fixed to the tower limb through the lower support, and the straight beam is fixedly connected to the tower limb through the upper support, this requires that the upper and lower supports at the corresponding upper and lower positions need to have high installation accuracy to ensure the stability and safety of the structure; in addition, although the triangular truss itself is a stable structure, in actual application, the spaced arrangement of the two triangular trusses may produce certain instability factors in the transverse direction of the bridge, especially under the influence of external factors such as self-weight and construction load.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.
