Detailed Implementation

[0020] Figs. 1~4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figs. 1~4 The present invention will be further described below.

[0021] like Fig. 1 As shown, a self-stabilizing initial support structure for cantilever scaffolding includes multiple steel cantilever beams 5 arranged side by side. The rear section of each steel cantilever beam 5 is located on the surface of the base plate 3, and each steel cantilever beam 5 is fixed to the surface of the base plate 3. The front section of each steel cantilever beam 5 extends outward from the edge of the base plate 3 to the outside of the base plate 3.

[0022] A fixing beam 6 is also provided on the upper surface of the section of the steel cantilever beam 5 located outside the base plate 3. The fixing beam 6 is perpendicular to the steel cantilever beam 5, and multiple fixing beams 6 are provided, arranged at intervals along the length of the steel cantilever beam 5 on the upper surface of the steel cantilever beam 5. Scaffolding 1 is arranged on the surface of the fixing beam 6. The structure of scaffolding 1 is implemented using conventional structures in this field. Under the support of the steel cantilever beam 5, the scaffolding 1 is located entirely outside the base plate 3.

[0023] The steel cantilever beam 5 and the fixed beam 6 are both implemented by the open channel steel in the art, and the adjusting fixing seat 4 is arranged on the surface of at least one steel cantilever beam 5. Fig. 2 The inclined pull rod 2 is further arranged, the bottom of the inclined pull rod 2 is connected with the adjusting fixing seat 4, and the upper end of the inclined pull rod 2 extends to the upper part of the scaffold 1 in an inclined manner and is fixed.

[0024] As known from the above, in the self-stabilizing structure of the cantilever scaffold, the inclined pull rod 2, the steel cantilever beam 5 and the scaffold 1 form a triangular structure, the self-stabilizing structure is realized without or without arranging the upper layer bottom plate and without the aid of the wall embedded part, and the stability of the scaffold 1 is improved.

[0025] As shown in Figs. 3~4 The adjusting fixing seat 4 includes the fixed plate 12 arranged horizontally, and one adjusting clamping plate 10 is arranged on each side of the lower surface of the fixed plate 12. The outer ends of the two adjusting clamping plates 10 are flush with the outer ends of the fixed plate 12, the inner ends of the two adjusting clamping plates 10 are inclined structures and are arranged in a spaced manner from the bottom surface of the fixed plate 12. The inner ends of the two adjusting clamping plates 10 are arranged in a spaced manner, and the spacing between the two adjusting clamping plates 10 is greater than the waist width of the waist of the channel steel (the steel cantilever beam 5) and less than the width of the top flange of the channel steel (the steel cantilever beam 5).

[0026] One adjusting bolt 13 is arranged on each side of the upper surface of the fixed plate 12, the adjusting bolt 13 penetrates the adjusting clamping plate 10 and one end of the fixed plate 12 from bottom to top on the corresponding side, and the adjusting bolt 13 is fixed by the nut after extending to the upper surface of the fixed plate 12.

[0027] The support pipe 11 is arranged at the middle part of the two adjusting bolts 13 and is fixed vertically on the surface of the fixed plate 12. The first hoop 7 is sleeved outside the support pipe 11, and the first hoop 7 is fixed in a lifting and rotating manner outside the support pipe 11 by the bolt in the first hoop 7. The second hoop 8 is further arranged on the side of the first hoop 7 and is rotatably arranged on the side of the first hoop 7. The bottom of the inclined pull rod 2 penetrates the inside of the second hoop 8, and the second hoop 8 is fixed with the inclined pull rod 2 by the fastening bolt 9 in the second hoop 8.

[0028] Since the adjusting fixing base 4 is slidably mounted on the surface of the profile steel cantilever beam 5, the adjustment of the fixing point of the diagonal pull rod 2 at the bottom before and after is realized, the adjustment of the fixing point of the diagonal pull rod 2 at the bottom up and down is realized through the first clamping hoop 7 which can be lifted, the adjustment of the fixing point of the diagonal pull rod 2 at the bottom at any rotating angle is realized through the rotating connection between the first clamping hoop 7 and the supporting pipe 11 and the rotating connection between the first clamping hoop 7 and the second clamping hoop 8, therefore, after the diagonal pull rod 2 is fixed, the diagonal pull rod 2 will not cause the force of the scaffold 1 and the profile steel cantilever beam 5 in other directions except the pulling force between the scaffold 1 and the profile steel cantilever beam 5, so that the bearing capacity of the initial support self-stabilizing structure of the cantilever scaffold is ensured.

[0029] The specific construction process is as follows:

[0030] Firstly, the profile steel cantilever beam 5 with a corresponding length is selected according to the distance of the outer exploration of the scaffold 1, and the profile steel cantilever beam 5 is fixed on the surface of the bottom plate 3, the distance of the outer exploration of the outer end of the profile steel cantilever beam 5 is not less than the width of the scaffold 1. The fixed beam 6 is arranged on the surface of the profile steel cantilever beam 5, and the scaffold 1 is arranged on the surface of the fixed beam 6.

[0031] The adjusting fixing base 4 is mounted from the inner end of the profile steel cantilever beam 5, the wing plate on the upper part of the profile steel cantilever beam 5 is clamped between the two adjusting clamping plates 10, after the adjusting fixing base 4 is moved to the appropriate position, the adjusting bolt 13 is locked, the fixed plate 12 and the adjusting clamping plate 10 are fixed, and the adjusting fixing base 4 and the profile steel cantilever beam 5 are fixed.

[0032] After the height of the first clamping hoop 7 and the relative angle with the supporting pipe 11 are adjusted, the first clamping hoop 7 and the supporting pipe 11 are fixed, after the relative angle between the second clamping hoop 8 and the first clamping hoop 7 is adjusted, the second clamping hoop 8 and the diagonal pull rod 2 are fixed through the fastening bolt 9, and the upper part of the diagonal pull rod 2 and the upper part of the scaffold 1 are fixed, so that the diagonal pull rod 2, the profile steel cantilever beam 5 and the scaffold 1 form a triangular structure, and the stability of the scaffold 1 is improved.

[0033] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to obtain equivalent embodiments. However, any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
