Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, an embodiment of the present invention provides a wall body unilateral formwork system, which includes a foundation guide wall 2, a panel 4, a keel structure and a supporting frame 9 sequentially disposed on a unilateral side of a wall body 1, wherein the supporting frame 9 is disposed on a foundation slab 3, and a foot margin 10 connected to a bottom of the supporting frame 9 is disposed on the foundation slab 3, and the foot margin 10 is an adjustable foot margin; the wall body unilateral formwork system further comprises foundation bolts 11, fixing rods corresponding to the upper portions of the foundation bolts 11 are arranged on the supporting frame 9, and after the upper portions of the foundation bolts 11 penetrate through the fixing rods, I-shaped steel communicating parts 14 are pressed and fixed with the fixing rods through gaskets 13 and double nuts 12.
As shown in fig. 1, the supporting frame 9 comprises a vertical rod, a cross rod and an inclined rod which are connected in sequence, one side of the vertical rod is connected with the keel structure, the cross rod is vertically connected with the bottom of the other side of the vertical rod, one end of the inclined rod is connected with the end of the cross rod, and the other end of the inclined rod is connected with the vertical rod.
The ground feet 10 are arranged at one ends of the cross rods connected with the inclined rods.
In this embodiment, the keel structure includes secondary joist 5 and main joist 6, secondary joist 5 with main joist 6 all adopts the ladle wood, can satisfy the strength requirement, multiplicable turnover number of times simultaneously.
As shown in fig. 1 and 2, the lower portion of the anchor bolt 11 is embedded in the foundation slab 3, the upper portion of the anchor bolt 11 extends out of the foundation slab 3 and then extends obliquely upward, and the fixing rod is perpendicular to the upper portion of the anchor bolt 11.
