Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a king's style of calligraphy end bucking restraint is supported, including core 1, sleeve 2, angle steel 3, adhesive-free material 4, filling material 5, stiffening rib 6, antislip strip 7 and end board 8, core 1 sets up inside sleeve 2, core 1 is hot rolling H shaped steel or welding type H shaped steel, 1 upper end of core and lower extreme both sides meet with the activity of angle steel 3 respectively, the upper end and the lower extreme of core 1 all are provided with adhesive-free material 4, adhesive-free material 4 is 2mm thick waterproofing membrane, be provided with filling material 5 between the upper surface of core 1 and the inner wall of lower surface and sleeve 2, filling material 5 is C30 pea gravel concreten, the web both sides of core 1 all are provided with one or more stiffening rib 6 perpendicularly, the length of stretching into sleeve 2 of stiffening rib 6 is 250mm, core 1 intermediate position is provided with antislip strip 7, sleeve 2 both ends are provided with end board 8 respectively.

As shown in fig. 5, the sleeve 2 is a rectangular steel pipe, the upper end and the lower end of the two side surfaces of the sleeve 2 are respectively provided with a plurality of welding holes 21, the distance between each row of welding holes 21 is 1m, the aperture of each welding hole 21 is 6mm, and the sleeve 2 is plug-welded with the angle steel 3 through the welding holes 21.

As shown in fig. 6, the end plate 8 is provided with a king-shaped through groove, the end parts of the core material 1 and the stiffening ribs 6 are movably arranged in the king-shaped through groove, and the end plate 8 is only welded with the sleeve 2 and is not welded with the core material 1 and the stiffening ribs 6.
