Description

Technical Field

[0001] The utility model relates to the technical field of high-speed box girder formwork, in particular to a common bracket for side beams in a high-speed box girder formwork. Background Art

[0002] In the field of transportation engineering, the prefabricated small box girder structure adopts a layout form of side beams on both sides and several middle beams. The prefabricated box girder in this structure is composed of three components: bottom plate, web plate and top plate. There are significant differences in the design of the middle beam and side beams, such as Figure 1 and Figure 2 As shown, Figure 1 This is a structural diagram of the existing side span beam. Figure 2 This is a structural diagram of the existing side span outer beam. The two are mainly reflected in the change of the wing plate width. The traditional prefabricated construction method often relies on fixed formwork technology, that is, designing and processing exclusive formwork for the different specifications of the center beam and side beam.

[0003] For example, Chinese patent CN219666973U discloses a prefabricated box girder formwork for high-speed railways. This allows for efficient reuse of formwork, meeting the construction requirements of prefabricated box girders at different angles. However, the formwork for the center beam and side beams cannot be mixed, requiring optimized designs for each beam. Therefore, exploring new technologies that can allow for the mixed use or rapid conversion of formwork for center beams and side beams is crucial for further improving the construction efficiency and cost-effectiveness of prefabricated small box girder structures. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then proposes a common bracket for side beams in a high-speed box beam template.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A common bracket for side beams in a high-speed box girder template includes a base frame, a side frame is provided on each side of the base frame, the base frame and the side frame are fixedly connected together, a web template is provided on the base frame and the side frame, wing plate replacement templates are provided at both ends of the web template, and sealing parts are provided at the ends of the wing plate replacement templates.

[0007] Furthermore, the side frame includes a bottom support, a bottom plate is provided on the bottom support, a vertical plate is provided on the bottom plate, an upper support plate is provided on the vertical plate, a side plate is provided between the upper support plate and the bottom plate, an outer support is provided on the side of the vertical plate away from the upper support plate, a fixing plate is installed on the outer support, and a pull rod is provided between the two vertical plates.

[0008] Furthermore, the web template is fixedly connected to the wing plate replacement template by bolts.

[0009] Furthermore, the wing panel replacement template is a side beam replacement block.

[0010] Furthermore, the blocking member includes a sliding rod, the end of which is provided with an adjustable side beam baffle. The sliding rod can slide along the vertical plate and the fixed plate and be fixed by bolts and nuts. The adjustable side beam baffle cooperates with the side beam replacement block.

[0011] Furthermore, the vertical plate and the fixed plate are provided with through holes for accommodating the insertion of the sliding rod.

[0012] Furthermore, the wing panel replacement template is a center beam replacement block.

[0013] Furthermore, the blocking member is a center beam comb plate, and the center beam comb plate is fixedly connected to the center beam replacement block.

[0014] Furthermore, an inner mold is provided at the center of the web template.

[0015] Compared with the existing technology, the present invention has the following advantages: it can achieve efficient sharing of formwork for the center beam and side beams, significantly reducing formwork investment and production costs. By sharing the bracket and web formwork, the different requirements of the center beam and side beams can be met by simply replacing the flange formwork, greatly improving formwork utilization and construction efficiency.
