[0037] The utility model will be further described below in conjunction with the accompanying drawings:

[0038] See also Figures 1 to 13 As shown, the utility model provides an anchor rod lattice beam slope scaffolding 1, comprising: a vertical pole 11, an oblique cross bar 12 perpendicular to the pole 11, and a transverse sweeping rod 13 and a longitudinal sweeping rod 14 installed at the bottom of the pole 11, the pole 11 comprises an inner pole 111 and an outer pole 112, the transverse sweeping rod 13 and the longitudinal sweeping rod 14 are connected to the inner pole 111 and the outer pole 112 through a rotating fastener 113, the oblique cross bar 12 is connected to the inner pole 111 and the outer pole 112 through a cross fastener 114; the inner pole 111 is tied to an anchor rod 21 pre-buried in the slope 2 through a wall connecting member 15, and the wall connecting member 15 comprises a wall connecting member inner rod 151 , an outer rod 152 of the wall connection member and a steel pipe 153 of the wall connection member, an inner rod 151 of the wall connection member is pre-buried in the slope 2 and welded to the anchor rod 21, one end of the outer rod 152 of the wall connection member is threadedly connected to the inner rod 151 of the wall connection member through a tapered sleeve 154, the other end of the outer rod 152 of the wall connection member is connected to the steel pipe 153 of the wall connection member, and the steel pipe 153 of the wall connection member is connected to the inner vertical rod 111 through a steel pipe fastener 155; by setting the tapered sleeve 154 for the connection between the outer rod 152 of the wall connection member and the inner rod 151 of the wall connection member, it is convenient to temporarily remove and restore the outer rod 152 of the wall connection member, and setting the sleeve 154 to a cone also facilitates the installation and removal of the sleeve 154.

[0039] It is worth mentioning that please refer to Figure 3As shown, during the construction of the lattice beam foundation 4, a template 24 for supporting the template before pouring the lattice beam concrete and a reinforcing wood square back rib 25 located outside the template 24 for reinforcing the template before pouring the lattice beam concrete are provided on the slope surface 23, and the outer rod 152 of the wall connecting member avoids the reinforcing wood square back rib 25 and passes through the template 24 and is threadedly connected with the inner rod 151 of the wall connecting member;

[0040] When the template 24 is removed, the outer rod 152 of the wall connecting member is temporarily removed first, and then the outer rod 152 of the wall connecting member is installed on the inner rod 151 of the wall connecting member after the template 24 is removed, so as to form a Figure 4 The lattice girder formwork 24 is shown in a state after being removed.

[0041] When the wall connecting member 15 is removed, the outer rod 152 of the wall connecting member is removed first, and then the conical sleeve 154 is taken out. Finally, the hole left by the conical sleeve 154 is sealed with cement mortar 5, so as to form a Figure 5 The state after the wall connection parts are removed is shown.

[0042] The anchor lattice beam slope scaffolding provided by the utility model adopts a double-row structure of inner uprights and outer uprights, connects the inner uprights and the outer uprights by oblique cross bars, and arranges wall connecting pieces on the inner side of the scaffolding, so that the inner uprights are connected with the anchor rods pre-buried in the slope through the wall connecting pieces, thereby ensuring the stability of the scaffolding frame and improving the safety of high-altitude operations; since the wall connecting pieces are constructed as a structure in which the outer rod of the wall connecting piece is threadedly connected to the inner rod of the wall connecting piece, the wall connecting piece is easy to assemble and disassemble, further improving the convenience of erecting and disassembling the scaffolding.

[0043] Specifically, in this embodiment, the arrangement of the anchor lattice beam slope scaffolding is as follows: Fig.13 The horizontal distance d1 of the scaffold shown is about 1.05m, the height step h is between 1.8-2.0m, the diagonal layout d2 is not greater than 2.2m, the vertical distance is about 1.5m (not shown in the figure), and the total height of the scaffold is not greater than 15m (not shown in the figure).

[0044] As a preference, see Figure 2 , Figure 6 As shown, the arrangement positions of the vertical poles 11 are all provided with first pads 31, which are anchored on the concrete foundation 3 by expansion bolts 32, and the vertical poles 1 abut against the first pads 31. Specifically, the first pads are made of 150*150*18mm plywood, and the first pads are anchored to the concrete foundation 3 by M10 expansion bolts to resist the oblique side sliding force of the vertical poles 1.

[0045] For further information, see Figure 6As shown, the angle formed between the bottom end face of the upright pole 1 and the first pad 31 is tightened by a wooden wedge 33, and the wooden wedge 33 is fixed to the first pad 31 by a cement nail 34. By arranging the wooden wedge 33 between the bottom end face of the upright pole 1 and the first pad 31, it is ensured that the bottom end face of the upright pole 1 is subjected to uniform force.

[0046] It is worth noting that if Fig.10 As shown, the axial force N is calculated by the slope angle θ and the uprights. The calculated axial force N of the uprights can be obtained by calculating the weight of the scaffolding itself. According to the formula F=N*cosθ, the design value of the lateral horizontal force F can be calculated. The uprights and the foundation must maintain balance, and it is necessary to ensure that the actual anti-slip force in the horizontal force direction is greater than the design value of the lateral horizontal force F; therefore, by arranging a first pad at the upright arrangement position and arranging a wooden wedge between the bottom end face of the upright and the first pad, the oblique lateral sliding force of the upright can be effectively resisted and the bottom end face of the upright can be ensured to be evenly stressed.

[0047] As a preference, see Figure 2 , Figure 7 , Fig. 9 As shown, one end of the oblique cross bar 12 is connected to a second pad 121, and the oblique cross bar 12 is vertically supported on the slope surface 23 of the slope 2 through the second pad 121; a plurality of nails 122 are provided on the second pad 121, one end of the nail 122 is inserted into the second pad 121, and the other end is inserted into the oblique cross bar 12.

[0048] Specifically, the second pad 121 is made of 150*150*18mm plywood, such as Figure 7 , Figure 8 Drive three 5 cm nails into the second pad 121 as shown, or Fig. 9 As shown, a 5 cm nail is driven into the middle of the second pad 121, the nail is driven into the second pad 121 by 10-15 mm, and the exposed part of the nail cap is inserted into the oblique cross bar 12, so that the second pad 121 is connected to the oblique cross bar 12 to prevent the second pad 121 from loosening or sliding down.

[0049] Preferably, vertical scissor braces (not shown) are provided at intervals of 15 m on the outside of the outer pole 112 in the longitudinal direction, and the width of the scissor braces is not less than 4 spans.

[0050] As a preference, see Figure 2 As shown, a zigzag diagonal brace 16 is provided at the end of the scaffold 1 , and the zigzag diagonal brace 16 is connected to an inner upright pole 111 and an outer upright pole 112 located at the end of the scaffold 1 .

[0051] As a preference, see Fig.10As shown, soil nails 22, such as steel bar soil nails or steel pipe soil nails, are pre-buried between the anchor rods 21 to serve as the tie points of the wall ties 15, and the wall ties 15 at opposite positions are welded to the soil nails 22. By adding steel bar soil nails or steel pipe soil nails, the anchor rods are replaced as the tie points of the wall ties at the positions where there are no anchor rods 21. The steel bar soil nails or steel pipe soil nails are much smaller than the anchor rods in terms of force performance, and the construction is also simpler.

[0052] Specifically, in one example, the following is used: Fig.11 , Fig.12 The steel flower pipe soil nail 22 shown in the figure has a pointed cone-shaped head welded to the steel pipe head 221 to facilitate driving into the soil. 1 / 2 of the entire length of the steel pipe is welded with a steel bar or angle steel barb 222. The barb 222 is welded symmetrically along the circumference of the steel pipe. The barb 222 is arranged close to one end of the steel pipe head 221, and a grouting circular hole 223 is set behind the barb 222.

[0053] As a preference, see Figure 1 As shown, horizontal rods 17 are installed on the vertical rods 11. The horizontal rods 17 include transverse horizontal rods 171 and longitudinal horizontal rods 172 installed on the transverse horizontal rods 171. Scaffolding boards 18 are laid on the transverse horizontal rods 171 and the longitudinal horizontal rods 172 to form a slope construction operation platform.

[0054] For further information, see Figure 1 As shown, a handrail 19 is installed on the outside of the scaffolding board 18. When the slope angle θ is greater than 65 degrees, the handrail 19 is installed on the outer pole 112; when the slope angle θ is less than 65 degrees, as shown in FIG. Fig.13 As shown, guardrail uprights 191 are firstly added to the oblique crossbar 12 and the outer uprights 112 , and then the handrail 19 is installed on the guardrail uprights 191 .

[0055] Passage entrances and exits are set on both sides of the scaffolding (not shown in the figure), and construction workers enter the passage from the side of the slope; further, up and down passages are set in the middle of the scaffolding, and safety belt hanging points with a spacing of 1m are required on both sides of the scaffolding.
