Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

Example 1: the utility model provides a strength nature post crab-bolt and pre-buried bearing structure of shaped steel post simultaneously, as shown in figure 1, including the square rail of penetrating from top to bottom, square rail includes vertical angle bar 1 of establishing in the four corners department and the crossbeam 2 that is used for connecting adjacent angle bar 1, and adjacent angle bar 1 all is through two crossbeams 2 fixed connection that are parallel to each other from top to bottom.

The protection rod 3 that the equidistance was arranged is vertically fixed on crossbeam 2, and the upper end of protection rod 3 extends to the top of the crossbeam 2 of the top, and the upper portion of protection rod 3 is equipped with the external screw thread. The external thread on the upper part of the guard bar 3 is matched with the nut to be used for connecting the flange plate at the bottom of the section steel column.

The periphery of the square fence is fixedly provided with an inclined supporting plate which extends towards the outside of the square fence and inclines downwards, the lower end of the inclined supporting plate is flush with the bottom of the square fence, and the inclined supporting plate is used for preventing the square fence from toppling under the action of external force.

As shown in fig. 1 and 2, each angle iron 1 is fixedly provided with a first inclined supporting plate 4 and a second inclined supporting plate 5. The length of the inclined supporting plate is adjustable, the inclined supporting plate comprises a first inclined supporting plate 4 extending in the left-right direction and a second inclined supporting plate 5 extending in the front-back direction, and the first inclined supporting plate 4 and the second inclined supporting plate 5 are identical in structure.

As shown in fig. 3, the first inclined supporting plate 4 includes a sleeve plate 6 and a movable plate 7, the sleeve plate 6 is a hollow bar-shaped plate structure, the movable plate 7 is a solid bar-shaped plate structure, a slot for inserting the movable plate 7 is formed inside the sleeve plate 6, the sleeve plate 6 is provided with a through first screw hole, the movable plate 7 is provided with a plurality of second screw holes 702 arranged at equal intervals along the length direction of the movable plate 7, the first screw hole can correspond to one of the second screw holes 702, and the sleeve plate 6 and the movable plate 7 are fixedly connected by a bolt 8 penetrating through the first screw hole and one of the second screw holes 702; the lower end of the movable plate 7 is provided with an arc-shaped clamping groove 701 for clamping the reinforcing steel bars of the raft.

The working principle is as follows: after the square fence is placed on the raft, the lower ends of the angle irons 1 are inserted between reinforcing steel bars of the raft.

And mounting a flange piece at the lower end of the section steel column to be mounted on the upper part of the protective rod 3, and fixing by adopting a nut.

Adjusting the length of the first inclined supporting plate 4 to enable the arc-shaped clamping grooves 702 at the lower end of the first inclined supporting plate 4 to clamp raft reinforcing steel bars on the left side and the right side extending in the front-back direction, and then fixing the adjusted length of the first inclined supporting plate 4 by using nuts 8;
