Embodiment 1
[0023] see Figure 1-Figure 2 , a rotary anti-return device for hanging baskets, including a set of rotary anti-return single pieces (the numerical control of the rotary anti-back single pieces can be arranged in parallel according to actual conditions), the rotary anti-back single The parts include shear arm 1, base 2 and rotating structure 3.
[0024] The shear arm 1 includes a shear arm body detachably connected to the concrete box, wherein the shear arm 1 is a rectangular cavity welded by six plates, and the side lengths of the top plate 1.1 of the rectangular cavity are equal It is 1 to 1.2 times the length of the corresponding side at the top of the four side panels.
[0025] Base 2 is used to fix the base body with the main longitudinal beam of the hanging basket. It is an open rectangular cavity formed by welding a bottom plate and four side plates. There are two side plates opposite to each other. A circular hole 2.1 is provided, and the circular holes 2.1 on the tw...

The invention provides a rotary retaining device for construction cradles. The device comprises at least one group of rotary single retaining parts. Each rotary single retaining part comprises a shear-resistant arm, a base and a rotating structure, wherein the shear-resistant arm comprises a shear-resistant arm body; the base comprises a base body and a round hole with an internal thread, and the round hole is formed in the base body; the rotating structure comprises a screw rod and a tightening part, the screw rod is provided with an external thread matched with the internal thread of the round hole, the screw rod penetrates the round hole, and the tightening part is arranged on the screw rod. The rotary retaining device is stable in structure, effective in retaining, convenient and quick in mounting, simple in operation, attractive in appearance, economical, available for bidirectional adjustment in occurrence of pre-embedding errors, wide in application range and suitable for construction of any construction cradles. The invention further discloses a retaining method of the rotary retaining device. The method includes: mounting the shear-resistant arms and the bases, and rotating the screw rod to enable the sliding structures to closely fit the corresponding shear-resistant arms to complete a retaining process, so that construction cradle retaining is realized.
Description
technical field [0001] The invention relates to the field of hanging basket construction, in particular to a rotary anti-backward device and an anti-backward method for hanging baskets. Background technique [0002] Hanging basket is an important temporary equipment for bridge cantilever construction, suitable for various types of bridges, such as girder bridges, rigid frame bridges, arch bridges, cable-stayed bridges, etc. In recent years, there are many forms of hanging baskets used in concrete suspension grouting construction at home and abroad, each with its own characteristics, such as parallel truss type, flat chord without counterweight type, bow string type, rhombus type, sliding cable-stayed type, prestressed cable-stayed formula etc. There are so many hanging baskets at home and abroad, but the proportion of hanging baskets that can really be used for walking on large slopes is extremely small. Along with the popularization and application of bridges containing c...
