Problems solved by technology
[0002] At present, small-diameter concrete columns are more and more widely used in engineering construction. When the building height is high, the concrete columns need to be poured in sections. Grinding with ash or sticking sponge rubber strips to stop leaks, after demolition, it is easy to form common concrete quality problems such as honeycomb, pockmarked surface, and wrong platform at the construction joints

Embodiment 1
[0014] Such as figure 1 and 2 As shown, the reinforcement device of the small-diameter concrete cylindrical formwork of the present invention includes four limiting plates 6 , two tensioning screws 3 , four U-shaped clamps 4 and four fixing nuts 2 .
[0015] Wherein, a semicircular notch is provided at one side edge of each limiting plate 6, and two semicircular notches of the limiting plates 6 are combined to form two intermediate clamping layers, and the two intermediate clamping layers The layers are respectively used to be clamped at the butt joint edges of the two column molds 5 that are butted up and down; two pull screws 3 are arranged in parallel between the upper and lower middle clamping layers; four U-shaped clamps 4 are respectively sleeved on On the four ends of the two paired pull screws 3, and each U-shaped holder 4 is buckled and pressed on the same side edges of the upper and lower middle clamping layers at the same time; the four fixing nuts 2 are respective...

The invention discloses a reinforcing device for a small-diameter concrete cylindrical molding board. The reinforcing device comprises four limiting plates, two opposite-pulling screws, four U-shaped clamping bases and four fixing nuts, wherein a semicircular notch is formed in the side edge at one side of each limiting plate; after being spliced, the semicircular notches of every two limiting plates form two middle clamping layers which are respectively used for clamping butt-joint side edges of two pillar moulds in butt joint; the two opposite-pulling screws are arranged between upper and lower middle clamping layers in parallel; the four U-shaped clamping bases are respectively arranged on four end heads of the two opposite-pulling screws in a sleeving mode, and each U-shaped clamping base is simultaneously buckled on same-side side edges of upper and lower middle clamping layers; and the four fixing nuts are respectively screwed on four end heads of the two opposite-pulling screws to clamp the four U-shaped clamping bases. The reinforcing device can effectively prevent a butt-join seam of the upper and lower pillar moulds from problems of a honeycomb, a pitted surface and slab staggering, and has a relatively good application prospect.
Description
technical field [0001] The invention relates to a construction device for a small-diameter concrete cylinder, in particular to a reinforcement device for a formwork of a small-diameter concrete cylinder. Background technique [0002] At present, small-diameter concrete columns are more and more widely used in engineering construction. When the building height is high, the concrete columns need to be poured in sections. Sanding with ash or pasting sponge strips to plug leaks will cause common concrete quality problems such as honeycombs, pockmarks, and misalignment at the construction joints after the formwork is removed. Contents of the invention [0003] The purpose of the invention: to provide a reinforcement device for butt pouring of small-diameter concrete cylindrical formwork. [0004] Technical solution: The reinforcing device of the small-diameter concrete cylindrical formwork of the present invention includes four limiting plates, two tensioning screws, four U-sh...
