Preferably, corresponding connection holes are respectively provided on the contact surfaces of the flat plate and the connector flat plate.

Preferably, at least one installation hole is respectively provided on the horizontal plate, joint horizontal plate and movable connection plate.

The beneficial effects of the utility model are: a vertical movable back corrugated for building formwork, the back corrugated is directly hung on the vertical formwork L-shaped connecting piece of the vertical formwork, and the end is locked with the plane formwork through the joint structure, The vertical formwork has good rigidity like the ribbed formwork, and at the same time, the back corrugation should be continuous and integral, so that multiple vertical formworks can be integrated to improve the integrity of the vertical formwork; moreover, the vertical movable back corrugation, including Common thickness modulus section plus non-used constant modulus section and movable connection plate; the combination of the two can meet the requirements of different thickness modulus changes. The back flute is made of lightweight and durable aluminum alloy material. Energy saving and environmental protection, while simplifying the assembly scheme of plate formwork, the assembly is smooth, saving materials and labor, and simplifying the formwork structure. The assembly process of similar templates improves work efficiency.

detailed description

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Figures 1, 2, and 3, a vertically movable back flute for building templates includes a back flute and a joint structure connected to the back flute. The back flute includes two flat plates 1 and is arranged on two The horizontal plate 2 between the flat plates 1, the horizontal plates 2 are uniformly respectively between the flat plates 1; the joint structure includes two joint flat plates 3 and a joint horizontal plate 4 arranged between the two joint flat plates 3; The two joint plates 3 mentioned above are arranged on the outer sides of the two plates 1 respectively; Wherein, the plate 1 and the horizontal plate 2 are fixedly connected by welding.

The movable connecting plate 5 is installed between two flat plates 1 through a mortise and tenon connection structure; the two sides of the movable connecting plate 5 are respectively provided with tenons 51; Mortise 11.

The width of the flexible connecting plate 5 is smaller than the width of the flat plate 1 . Both end faces of the movable connecting plate 5 are not flush with the end faces of the flat plate 1 .

Corresponding connecting holes 12 are respectively provided on the contact surfaces of the flat plate 1 and the connecting flat plate 3 . The inside of the connection hole 12 is fixedly connected by a bolt connection, and the connection is stable.

The horizontal plate 2 , the joint horizontal plate 4 and the movable connecting plate 5 are respectively provided with installation holes 6 .

When in use, the back flute is closely attached to a plurality of vertical templates 7 spliced with each other, and the joint structure is attached to the bottom of the plane template 8 . Wherein, the vertical formwork 7 has a vertical formwork L-shaped connecting piece 71, and the L-shaped connecting piece 71 and the horizontal plate 2 are connected through a bolt connection; Fixed connection.

The utility model relates to a vertical movable back corrugated for building formwork, the back corrugated is directly hung on the vertical formwork L-shaped connecting piece 71 of the vertical formwork 7, and the end is locked with the plane formwork 8 through the joint structure. Tight, so that the vertical formwork 7 has good rigidity like a ribbed formwork, and at the same time, it should be back corrugated and continuous, so that multiple vertical formworks 7 are integrated, and the integrity of the vertical formwork 7 is improved; Movable back corrugation, including commonly used plate thickness modulus section plus non-used constant modulus section and movable connecting plate 5; the combination of the two can meet the changing requirements of different plate thickness modulus. The back flute is made of lightweight and durable aluminum alloy material. Energy saving and environmental protection, and at the same time simplify the assembly plan of plate formwork, save materials and labor, simplify the formwork structure, its structure is simple, easy to use, simple to operate, simple to make, reduce production costs, save resources, and simplify the production of plate formwork Assembling process improves work efficiency.

Inspired by the above-mentioned ideal embodiment according to the utility model, and through the above-mentioned description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model.
