[0001] The utility model relates to the technical field of water conservancy and building construction, in particular to a formwork structure for an upward-turned circular arc wall / plate. Background Art

[0002] In the field of water conservancy construction, a sluice gate usually consists of a gate chamber and upstream and downstream connecting sections. When the designed water retaining level of the sluice gate is higher than the discharge control water level and the height difference between the two is large, a breast wall is usually set up to reduce the gate height and reduce the gate opening and closing force. The breast wall is generally a reinforced concrete structure, and the connection with the gate pier is either fixed or simply supported. The structure has a combination of a wedge-shaped plate that is thin on the top and thick on the bottom, and a beam-slab.

After each vertical tension bolt 15 penetrates the top beam 11, an inner horizontal bar 10, an outer horizontal bar 10, the platform formwork 1 and the bottom beam 12 in sequence, the two ends of each vertical tension bolt 15 are respectively correspondingly locked to the top beam 11 and the bottom beam 12; the first side beam 13 and the second side beam 14 are respectively correspondingly abutted against the outer sides of the plurality of fan-shaped vertical plates 8 and the plurality of L-shaped vertical plates 9.

[0026] It should be noted that the bottom beam 12 and each vertical tension bolt 15 should be staggered with the supporting frame 3 below in space to avoid mutual interference.

[0027] In the utility model, a plurality of L-shaped vertical plates 9 are fixedly connected to the outer sides with reinforcing cross beams 17 , and the outer sides of the reinforcing cross beams 17 are fixedly connected to the reinforcing vertical beams 18 , thereby playing the role of reinforcing the upward-turned arc wall / plate formwork assembly 2 .

[0032] After the upward-turned arc wall / plate platform formwork 2, namely the inner arc formwork 4 and the outer arc formwork 5, are assembled at the construction site, steel bars are laid on the platform formwork 1 and in the arc-shaped channel 6.

[0033] Next, the top beam 11 and the bottom beam 12 are respectively connected to the top ends of several fan-shaped vertical plates 8 and the bottom surface of the platform formwork 1, and then the vertical tension bolts 15 are respectively passed through the top beam 11, an inner horizontal bar 10, an outer horizontal bar 10, the platform formwork 1 and the bottom beam 12 in sequence, so that the two ends of each vertical tension bolt 15 are respectively locked to the top beam 11 and the bottom beam 12.

[0034] During the specific construction, it should be ensured that the bottom beam 12 and each vertical tension bolt 15 are staggered in space from the supporting frame 3 below, so as to avoid mutual interference.
