Embodiment 1

[0026] see Figure 1-Figure 2 , a sliding anti-back device for hanging baskets, including a set of sliding anti-back single pieces (the number of sliding anti-back single pieces can also be arranged in parallel according to actual conditions). The return unit includes a shear arm 1, a base 2 and a sliding structure 3.

[0027] The shear arm 1 includes a shear arm body detachably connected to the concrete box. The shear arm body is composed of a screw rod 1.1, a top cap 1.2 and a hook ring 1.3. The top cap 1.2 is welded on the upper end of the screw rod 1.1 , The hook ring 1.3 is welded on the top cap 1.2, wherein the outer diameter of the top cap 1.2 is 1 to 1.2 times the outer diameter of the screw mandrel 1.1.

[0028] The base body used for fixing to the main longitudinal beam of the hanging basket in the base 2 is welded by a top plate 2.1 and two end plates 2.2, and the shape is concave. Two sets of elongated hole groups are arranged symmetrically on the top plate 2.1, ...

Abstract

The invention provides a sliding type retaining device for construction cradles. The device comprises at least one group of sliding type single retaining parts. Each sliding type single retaining part comprises a shear-resistant arm, a base and a sliding structure, wherein the shear-resistant arm comprises a shear-resistant arm body; the base comprises a base body for fixing and long hole groups in the base body, and the length direction of the long hole groups is identical to a traveling direction of the construction cradles; the sliding structure comprises a supporting plate and a contact component, the supporting plate is movably arranged on the base body, the contact component contacts with the shear-resistant arm body, and the supporting plate is provided with mounting hole groups matched with the long hole groups. The sliding type 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 sliding type retaining device. By mounting of the shear-resistant arms and the bases and adjustment of bolts, the sliding structures can closely fit the corresponding shear-resistant arms to complete a retaining process, and great retaining effects are achieved.

Description

technical field [0001] The invention relates to the field of hanging basket construction, in particular to a sliding-type 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 contai...
