Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

As shown in fig. 1 and 2, this embodiment provides an adjustable shaped steel strutting arrangement for scaffold frame encorbelments, and it is including setting up wallboard preformed hole 3 of seting up in end bearing plate 2 and the prefabricated wallboard 1 of one side of prefabricated wallboard 1, and the opposite side of placing prefabricated wallboard 1 behind end bearing plate 2 and the wallboard preformed hole 3 is worn to establish by the end of wearing to utilize first high-strength bolt 4 to adopt the locking of first double-nut 5, all press from both sides between end bearing plate 2 and the first high-strength bolt 4 and between the opposite side of prefabricated wallboard 1 and the end of wearing to establish of first high-strength bolt 4 and be equipped with first gasket 6.

The upper and lower both ends of end carrier plate 2 are fixed with backup pad 7 and bottom suspension fagging 8 respectively, it has the tip of the I-steel girder 9 of encorbelmenting to go up to place between backup pad 7 and the bottom suspension fagging 8, it has stiffener 10 to encorbelment to weld between the I-steel girder 9 upper and lower parts, and the end of wearing to establish that utilizes second high strength bolt 11 wears to establish backup pad 7, stiffener 10 and bottom suspension fagging 8 to adopt the locking of second double nut 12, all press from both sides between backup pad 7 and the second high strength bolt 11 and between the end of wearing to establish of bottom suspension fagging 8 and second high strength bolt 11 and be equipped with second gasket 13.
