Problems solved by technology

[0003] There are several problems in the back flute of the prior art: first, steel back flutes are basically used in the market, resulting in heavy weight, difficult handling, long construction period, and prone to corrosion; second, most of the existing back flutes use channel steel , square tube, large amount of welding, the force of the weld after combination is easy to cause stress concentration

Abstract

The invention discloses an anti-corrosion aluminum formwork reinforcing back bar, which comprises single pipes and a connecting piece. The single pipes are extruded aluminum profiles, and the sectionof each single pipe is a closed cavity; grooves I and grooves II are formed in the two side faces of the cavities correspondingly, and reinforcing ribs for dividing each cavity into five chambers arearranged in the cavity; the connecting piece is a hollow aluminum pipe with the rectangular section; and the grooves I in the two single pipes are provided with outward openings, formed in a back-to-back mode and connected into a back bar plate single body structure through the hollow aluminum pipe arranged between the back faces of the two single pipes. According to the anti-corrosion aluminum formwork reinforcing back bar, the problems that rigidity is insufficient, and transformation is prone to occurring are solved while lightweight is ensured, and the hydrostatic pressure of concrete is resisted better; and chromized layers and electrostatic sprayed layers are arranged on the surfaces of the aluminum profile single pipes, abrasion resistance and anti-aging capacity of the back bar areimproved, the surface anti-corrosion capacity of the back bar is further improved greatly, and thus the service life of the aluminum alloy profiles can be effectively prolonged.

Description

technical field [0001] The invention belongs to the field of aluminum alloy formwork, and in particular relates to a corrosion-resistant aluminum formwork for reinforcing back corrugation. Background technique [0002] In the field of construction, aluminum alloy formwork has many advantages such as short construction period, many reusable times, low average cost of use, convenient construction, high efficiency, good stability, high bearing capacity, and environmental friendliness, and its application scope is gradually expanding. In order to ensure the surface flatness of cast-in-place concrete and resist the lateral pressure generated by pouring, it is necessary to use back corrugated reinforced formwork to prevent problems such as mold explosion and flatness out-of-tolerance. [0003] There are several problems in the back flute of the prior art: first, steel back flutes are basically used in the market, resulting in heavy weight, difficult handling, long construction per...
