Description

Technical Field

[0001] This utility model relates to a formwork support system for irregularly shaped beams. Background Technology

[0002] In construction projects, curved concrete beams are frequently encountered. When erecting these beams, curved beam formwork is required. For example, patent application CN202220617556.5, entitled "A Formwork Device for Rapid Construction of Curved Beams," includes a first formwork, a second formwork, crossbars, support rods, and baffles. The first and second formworks are connected by external bolts. Both ends of the first and second formworks are connected to baffles. Support rods are detachably connected to both sides of the first and second formworks, with crossbars overlapping the support rods. Insert holes are drilled through the formwork. Pads and connecting ears are fixed at equal intervals to the bottom of the formwork. Each support rod includes a support plate, hanging blocks, a rod body, and a base plate. The support plate is fixed to the upper part of the inner side of the rod body, the hanging blocks are snapped onto the top of the rod body, and the base plate is welded to the bottom of the rod body. While this formwork device, with support rods connected to the first and second formworks and baffles connected to their end faces, allows for rapid construction, it still has the potential for instability and cannot adjust the thickness of the curved beams it can cast.

[0023] For reference Figure 1 , Figures 4-7As shown, this application provides a support system for irregular beam formwork. The irregular beam is an arc-shaped beam, including an arc-shaped beam formwork assembly 1 and a support member 162 for supporting the arc-shaped beam formwork. The arc-shaped beam formwork assembly 1 includes an arc-shaped base plate 3, front and rear main plates 4, and left and right side plates 14. An adjustment member 5 is provided at the bottom of the front and rear main plates. The adjustment member 5 is used to adjust the width between the front and rear main plates 4 and limit the position of the arc-shaped base plate 3. The front and rear main plates 4 are connected to the left and right side plates 14 by fasteners 6. The arc-shaped base plate 3, the front and rear main plates 4, and the left and right side plates 14 are enclosed together by the adjustment member 5 and the fasteners 6 to form a pouring cavity, and concrete is poured into the pouring cavity. In order to prevent the formwork from bulging, tie rods 15 are provided between the front and rear main plates 4.

[0024] Specifically, the adjusting component 5 includes a horizontal concave-convex plate 51 at the bottom of the front and rear main plates 4. The horizontal concave-convex plate 51 is detachably connected to the front and rear main plates 4, facilitating demolding of the front and rear main plates 4 during subsequent demolding. Each protruding end of the horizontal concave-convex plate 51 has a groove, and a sliding block 52 is provided between the grooves at opposite protruding ends. Both sides of the sliding block 52 are connected to a bidirectional threaded rod 53 via a limiting ring. The distance between the front and rear main plates 4 is adjusted by rotating the bidirectional threaded rod 53. Each sliding block 52 has a vertical limiting part 7, which is configured in two ways.

[0025] like Figure 1As shown, both the front and rear main plates 4 have transverse protrusions on their outer ends. The transverse protrusions are used for the support member 162 to abut against and support the support member 162. The support member 162 includes a scaffold 17 that supports the entire arc beam template. A telescopic support rod 18 is hinged to the upper end of the scaffold 17. The end of the telescopic support rod 18 is provided with an abutment joint, which abuts against the lower end of the transverse protrusion, further improving the support force for the front and rear plates and preventing problems such as bulging and leakage of grout.

[0026] like Figures 2-3 , Figure 8 As shown, this second embodiment is basically the same as the first embodiment, except that: the support member 162 includes a main support part 19 and a side support part 20. The side support part 20 is used to support the front and rear main boards 4. The main support part 19 is used to support the entire arc beam template. The main support part 19 includes multiple support frames 21. Adjacent support frames 21 are connected to each other to form the required support length.

A telescopic abutment plate 22 is hinged in the groove and abuts against the lower end face of the transverse protrusion.

[0027] The above improvements are as follows: the support component 162 includes a main support part 19 and a side support part 20. The side support part 20 is used to support the front and rear main boards 4, and the main support part 19 is used to support the entire arc-shaped beam template. The main support part 19 includes multiple support frames 21. Adjacent support frames 21 are connected by double-headed clamps to form the required support length. The support frame 21 includes multiple symmetrically arranged lifting support columns 211. The lifting support columns 211 are hydraulic rods or multi-stage telescopic columns driven by motors. The upper end of each lifting support column 211 is connected to an abutment platform. 212, vertical plates 213 are fixedly provided on both sides of the abutment platform 212. The end face of the vertical plate 213 facing the front and rear main plates 4 is provided with a groove. A telescopic abutment plate 22 is hinged in the groove.
