Detailed Description

The following further describes embodiments of the present invention with reference to the drawings.

In the figure 1, the device comprises a panel 1, a secondary keel beam 2, a pressing plate 3, a truss 4, a top beam 4-1, a top beam side plate 4-11, a bottom beam 4-2, a bottom beam side plate 4-21, a support rod 4-3, an inclined support 4-4, a cross plate frame 5, a pair-penetrating pull rod 6, a winch 7, a fixing clamp 8, a positioning rod 9, an embedded pull rod 10 and the like.

As shown in figure 1, the invention relates to a concrete structure wall single-side formwork structure which comprises a panel 1, wherein a plurality of parallel secondary keel beams 2 are uniformly distributed on the surface of the panel 1, the secondary keel beams 2 are made of I-shaped steel and are made of aluminum materials, a plurality of trusses 4 are sequentially and vertically arranged on the secondary keel beams 2 along the length direction, each truss 4 comprises a top beam 4-1 and a bottom beam 4-2 which are arranged in parallel, the corresponding top beam 4-1 is vertically connected with the bottom beam 4-2 through a plurality of support rods 4-3, two inclined struts 4-4 are symmetrically arranged on two sides of each support rod 4-3, and the support rods 4-3, the adjacent inclined struts 4-4 and the corresponding top beam 4-1 or bottom beam 4-2 form a right-angled triangle.

The two ends of the top beams 4-1 which are arranged in parallel are respectively connected through a pressing plate 3.

The top beam 4-1 comprises two top beam side plates 4-11 which are arranged in parallel, one side end part of the diagonal brace 4-4 and the brace 4-3 extends into the space between the two top beam side plates 4-11 and is fixedly connected with the two top beam side plates 4-11; the bottom beam 4-2 comprises two bottom beam side plates 4-21 which are arranged in parallel, and the other end parts of the inclined strut 4-4 and the strut 4-3 extend into the space between the two bottom beam side plates 4-21 and are fixedly connected with the two bottom beam side plates 4-21.
