Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, and in particular to a suspended formwork support for a large cantilever cap beam with limited clearance. Background Technology

[0002] Large cantilever cap beams are a common structural form in urban viaducts. They are simple and elegant in design, with beautiful lines, and offer significant advantages for double-level traffic engineering, providing ample ground space beneath the cantilever sections. Large cantilever cap beams are typically constructed using ground-supported scaffolding. However, when the clearance beneath the cantilever is limited, such as when ground space needs to be used for vehicular traffic and heavy traffic makes it difficult to occupy surface roads, ground-supported scaffolding becomes impractical. Therefore, there is an urgent need for a formwork support structure for large cantilever cap beams that does not obstruct traffic flow below. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a suspended formwork support for large cantilevered cap beams with limited clearance.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a suspended formwork support for a large cantilever cap beam with limited clearance, comprising steel pipe columns, which are detachably installed on the top of the pier cap and located on the front and rear sides of the pier column. A load-bearing frame is installed on the top of the pier column, and a cap beam is installed on the top of the load-bearing frame. Several hanging rods are detachably installed obliquely between the steel pipe columns and the adjacent sides of the load-bearing frame. A transverse horizontal bracing is detachably installed between the tops of the opposite faces of two corresponding steel pipe columns on the left and right sides, and a longitudinal horizontal bracing is detachably installed between the tops of the opposite faces of two corresponding steel pipe columns on the front and rear sides.

[0005] Specifically, the outer wall of the steel pipe column is provided with a first ear plate corresponding to the top of the hanger, the transverse horizontal connection end, and the longitudinal horizontal connection end, and is bolted and fixed to the hanger, the transverse horizontal connection, and the longitudinal horizontal connection through the first ear plate.

[0006] Specifically, the load-bearing frame includes crossbeams, longitudinal beams, and horizontal braces. Several crossbeams are arranged side by side at equal intervals and are connected and fixed by two longitudinal beams. The two longitudinal beams are connected by several horizontal braces.

[0007] Specifically, the top of the crossbeam is provided with second ear plates on both the front and rear sides, corresponding to the bottom end of the hanger, and is bolted to the hanger through the second ear plates.

[0008] Specifically, the foundation is equipped with embedded parts, which are bolted to the steel pipe column.

[0009] Specifically, the transverse bracing consists of two parallel chords and two intersecting web members.

[0010] In particular, the longitudinal bracing consists of two parallel chords and two intersecting web members.

[0011] The beneficial effects of this utility model are: the structure of this utility model is easy and quick to install and dismantle, all components are connected by bolts, and the amount of on-site welding work is small; the support is a suspended structure, which does not affect the traffic flow of the road below the cantilever; it has wide applicability, high turnover rate of the support, and reduces project cost.

[0016] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figures 1-3 As shown, a suspended formwork support for a large cantilever cap beam with limited clearance includes steel pipe columns 11. The steel pipe columns 11 are detachably installed on the top of the pier cap 19 and located on the front and rear sides of the pier column 18. The pier cap 19 is provided with embedded parts 14, which are bolted to the steel pipe columns 11. The pier cap 19 is located below the ground line 20. The embedded parts 14 are installed in the pier cap 19 and are pre-embedded during the pouring of the pier cap 19 to fix the steel pipe columns 11 on the pier cap 19.

[0019] A load-bearing frame 12 is installed on top of the pier 18, and a cap beam 17 is installed on top of the load-bearing frame 12. The load-bearing frame 12 includes crossbeams 121, longitudinal beams 122, and horizontal braces 123. Several crossbeams 121 are arranged side by side at equal intervals and are connected and fixed by two longitudinal beams 122. The two longitudinal beams 122 are connected by several horizontal braces 123. The load-bearing frame 12 is located below the formwork of the cap beam 17 and is used to bear all the loads of the formwork and the pouring of the cap beam 17. The load-bearing frame 12 is a suspended structure and will not affect the traffic flow of the road in the clearance limit 21 below the cantilever. The number of crossbeams 121 should be determined according to the cantilever length of the cap beam 17 and the load size. The horizontal braces 123 can enhance the overall stability of the load-bearing frame 12.

[0020] Several hangers 13 are detachably installed diagonally between the steel pipe column 11 and the adjacent load-bearing frame 12. The outer wall of the steel pipe column 11 is provided with a first ear plate 111 corresponding to the top of the hanger 13, and is bolted to the top of the hanger 13 through the first ear plate 111. The front and rear sides of the top of the crossbeam 121 are provided with a second ear plate 124 corresponding to the bottom of the hanger 13, and is bolted to the bottom of the hanger 13 through the second ear plate 124. The hangers 13 effectively transfer the load on the load-bearing frame 12 to the steel pipe pile 11.

[0021] A transverse horizontal bracing 15 is detachably installed between the tops of the opposite faces of two corresponding steel pipe columns 11 on the left and right sides. A longitudinal horizontal bracing 16 is detachably installed between the tops of the opposite faces of two corresponding steel pipe columns 11 on the front and rear sides. The transverse horizontal bracing 15 consists of two parallel chords and two intersecting web members, and the longitudinal horizontal bracing 16 consists of two parallel chords and two intersecting web members. The outer wall of the steel pipe column 11 is provided with a first ear plate 111 corresponding to the connection end of the transverse horizontal bracing 15 and the connection end of the longitudinal horizontal bracing 16, and is bolted and fixed to the transverse horizontal bracing 15 and the longitudinal horizontal bracing 16 through the first ear plate 111. The transverse horizontal bracing 15 can enhance the overall transverse stability of the support structure, and the longitudinal horizontal bracing 16 can enhance the overall longitudinal stability of the support structure.

[0022] This utility model features a convenient and quick structure for installation and disassembly, with all components connected by bolts, minimizing on-site welding work. The support is a suspended structure, which does not affect traffic flow on the road below the cantilever. It has wide applicability, high support turnover rate, and reduces project costs.
