Cable trench combined formwork

Abstract

The invention discloses a cable trench combined formwork which comprises panels, middle upright posts, corner upright posts, fixing needles and supporting beams, wherein the middle upright posts and the corner upright posts are fixed on the ground through the fixing needles; the adjacent middle upright posts and / or corner upright posts are connected through the panels; and the strength between thepanels is increased through the supporting beams; first mounting grooves for fixing the panels are formed in the two sides of the middle upright posts, and first fixing holes for allowing the fixingneedles to pass through are formed in the middles of the middle upright posts in a penetrating mode; and the corner upright posts are of an L-shaped structure, and second mounting grooves for fixing the panels are formed in the two edges of the corner upright posts, and second fixing holes for allowing the fixing needles to pass through are formed in the middle of the corner upright posts in a penetrating mode. According to the cable trench combined formwork, through the split design of the fixing needles, the middle upright posts and the corner upright posts, a frame is convenient to assembleand splice; and the waist-shaped holes are formed, so that the positions of the middle upright posts and the corner upright posts can be finely adjusted, and the adaptability is better.

Description

technical field [0001] The invention relates to the field of construction, in particular to a composite formwork for cable trenches. Background technique [0002] Cable trenches are usually buried underground, and are often constructed at a later stage. The construction period is short and the construction conditions are poor. In particular, the construction space is limited. The construction cost is high, the quality is difficult to control, and the ready-made is messy, which makes it difficult to reflect civilized construction. Contents of the invention [0003] Aiming at the defects of the above prior art, the main purpose of the present invention is to overcome the deficiencies of the prior art, and discloses a cable trench combination formwork, including panels, middle columns, corner columns, fixing pins and support beams. The middle column and the corner column are fixed on the ground through the fixing pins, the adjacent middle columns and / or corner columns are co...
