A Quick Mounting and Dismounting Buckle Fixture for Cross Fixing Tubes for Concrete Formwork

Abstract

The invention discloses a quick crossed fixed pipe demounting and fastening fixture for concrete formwork. The quick crossed fixed pipe demounting and fastening fixture comprises two fasteners made of plastics, each fastener comprises a first side wall, a second side wall and a third side wall and is provided with a recess matched with a fixed pipe in shape, wherein the first, second and third side walls are sequentially connected together. The fasteners are connected back to back in a manner that the recesses face outwards. When the fixed pipes are fastened by the quick crossed fixed pipe demounting and fastening fixture, firstly, crossed fixed pipes are erected outside the concrete formwork spliced in a horizontal plane, the recess of one fastener is fastened on one fixed pipe at the cross of the two fixed pipes, and the recess of the other fastener is fastened on the other fixed pipe. The fasteners made of plastics have certain elastic deformation, so that the recesses can deform and expand and restore, and the two fasteners can be quickly respectively fastened on the two fixed pipes with slight force and can be quickly and conveniently demounted in a laborsaving manner. Besides, the fasteners cannot run out on the fixed pipes randomly, safety of fastening of the fasteners is ideal.

Description

technical field [0001] The invention relates to a buckle clamp for a cross fixing pipe for a concrete formwork. Background technique [0002] When splicing concrete formwork before pouring, multiple concrete formworks are spliced ​​together, and vertical fixed pipes are erected outside the concrete formwork, and two fixed pipes that intersect each other need to be fixed together. [0003] In order to solve the above-mentioned problems, the applicant applied for "a kind of cross-fixed pipe buckle clamp for concrete formwork" whose publication number is 102909779A, such as figure 1 As shown, it mainly includes two fasteners 10a and two locks 20a. The fastener 10a has a first side wall 11a, a second side wall 12a and a third side wall 13a which sequentially enclose an arc-shaped notch 14a, and the arc-shaped notch 14a matches the shape of the fixing pipe for the concrete formwork. The lock 20a is movably installed on the first side wall 11a of the fastener in such a way that ...

Problems solved by technology

[0005] However, a plurality of concrete formworks 1a are spliced ​​in the horizontal plane, and fixed pipes 2a intersecting each other are erected outside the concrete formwork 1a to support or fix the concrete formwork 1a. The lock piece 20a, for the fixed pipes 2a that cross and overlap each other in the horizontal plane, the fixed pipe 2a is clamped by the lock piece 20a, which is cumbersome to operate, and the clamping and disassembly are very slow
