Embodiment Construction

[0013] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the panel 1 of the present invention is a steel plate, and the back of each panel 1 is fixed together with the web bar 2 with bolts. The web 2 is made of channel steel and angle steel. The upper end of the inner chord 6 is provided with a wedge slot hole 15, and the lower end is provided with a positioning plate 17. The positioning plate 17 is provided with a wedge iron groove 16. The inner chord 6 of the upper and lower templates Through the wedge hole 15, the wedge iron and the positioning plate 17 are connected, the wedge iron is wedged into the overlapping slot of the wedge slot hole 15 and the wedge iron groove 16 on the positioning plate 17, so that it can bear the inner chord 6 of the upper and lower templates. At the same time, the setting of the wedge iron groove 16 also makes the distance between the inner chords 4 of the upper and lower formwork adjustable, which can ensure uninterrupted conti...

Abstract

A reversal moulding board of bidirectional curvature is enabled to be adjusted. It adopt at least two moulding board just upright to each other, each moulding board consists of faceplate, inner string pole, abdomen pole, outer string pole, aclinic regulate device, plumb regulate device, task flat roof, anchor wimble, anchor tendon. Inner string pole is fixed on back of the faceplate, outer string pole link to inner string pole by abdomen pole, task flat roof is mounted between inner and outer string pole. Aclinic regulate device consists of regulate pedestal and aclinic regulate pole, plumb regulate device consists of front crossbeam, front slippery block, back crossbeam, back slippery block, plumb regulate pole and cleat. Each moulding board has a row of anchor tendons. Middle and nether boards link to orientation board by with the wedge slot hole. Adopt the above structure, bidirectional curvature of the moulding board can be regulated, and sequentially reversal ascend fast, this invent device can adapt to construction of complicate shape, curvature variably roller concrete arched dam.

Description

technical field [0001] The invention relates to a formwork for concrete building construction, in particular to a two-way curvature-adjustable overturn formwork suitable for the construction of concrete arch dams with complex shapes and large curvature changes. Background technique [0002] At present, in the construction of hyperbolic RCC arch dams with large curvature at home and abroad, Doka cantilever formwork or flipped formwork are mostly used. Although the formwork can meet the requirements of continuous lifting, it cannot adjust the two-way curvature. Contents of the invention [0003] The purpose of the present invention is to provide a two-way adjustable flip template, which can overcome the above-mentioned deficiencies in the prior art. Accurately meet the construction requirements of hyperbolic RCC arch dams with large curvature, and the construction quality is good. [0004] The purpose of the prese...
