DETAILED DESCRIPTION

[0016] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0017] Example 1 like Figure 1~Figure 3 As shown, an attached scaffold of the present invention comprises a vertical pole 1, a guide rail 2, a wall-mounted support 3, a scaffolding board 4, an upper and lower lifting frame 5, and a supporting truss 10. When in use, a plurality of wall-mounted supports 3 are installed on a building wall 15, and the guide rail 2 is inserted into the wall-mounted support 3 and can move up and down, and the longitudinal height of the guide rail can be extended as required.

[0018] like Fig.28 As shown, the auxiliary support 11 is installed on the guide rail 2 by bolts, and the vertical pole 1 is installed on the auxiliary support 11. The scaffolding board 4 is horizontally set up on the auxiliary support 11, and the side of the scaffolding board 4 is connected to the vertical pole 1 and the guide rail 2 to form the scaffolding frame body.

[0019] The bottom and the middle upper part of the frame body are installed with upper and lower lifting frames 5, and the chain hoist 6 is hung on the upper and lower lifting frames 5. The chain of the chain hoist 6 passes through the lower upper and lower lifting frames 5, so that the chain of the chain hoist 6 rolls in a circle between the two upper and lower lifting frames 5 when driven. The lifting support 7 is installed on the building wall 15, and the lifting support 7 is fixedly connected with the chain of the chain hoist 6 by pins. When the chain hoist 6 is driven, the lifting support 7 is used as the fulcrum to lift the scaffold frame body.

[0020] In the specific application process, in order to ensure the stability of the scaffold frame body and the vertical posture of the scaffold frame body, when the scaffold is in a static use state, the guide rail 2 at the top position of the scaffold frame body is connected to the building wall 15 by using the inclined rod 14.

[0021] A flap 13 is installed at the bottom of the frame body through a hinge 4010. The flap 13 is folded when the frame body is lifted up and down. When the frame body is in static use, the flap 13 is opened and placed on the building wall 15 to prevent objects from falling from the gap between the frame body and the building wall 15 during construction.

[0022] like Figures 35-37 As shown, at the bottom of the frame body, a bottom support rod 8 is provided between the vertical pole 1 and the guide rail 2, a scaffolding board 4 is laid above the bottom support rod 8, and support trusses 10 are installed on both sides of the scaffolding board 4 to form a corridor for workers during construction and a construction platform outside the building. A protective net frame 12 is installed outside the vertical pole 1 of the frame body, and a protective layer diagonal rod 9 is installed between the vertical pole 1 and the guide rail 2 at the top of the frame body. The protective layer diagonal rod 9 can ensure the strength of the external vertical pole 1. The installation height is higher than the guide rail 2 to protect the peripheral safety of the construction at the top of the building.

[0023] In actual use, the attached lifting scaffolding is an external scaffolding that is erected at a certain height by rods and attached to the building wall 15. Relying on its own lifting equipment and devices, it can climb or descend layer by layer with the engineering structure. It has safety protection, anti-tilting, anti-falling and synchronous lifting functions.

[0024] Example 2 like Figure 4~Figure 6 As shown, in this embodiment, the specific shape of the rod body 1 is a hollow rectangle, and wing plates 101 are provided on both sides of the rod body 1. A plurality of connection holes 102 are provided on the rod body 1 and the wing plates 101. The wing plates 101 are provided with holes to connect with the steel plate protection net 12 and the support truss 10. The connection holes 102 on the wing plates 101 can be connected with the protection net frame 12 and the support truss 10. The connection holes 102 on the rod body 1 are connected with the scaffolding board 4, the auxiliary support 11, the bottom rod 8, the protection layer inclined rod 9, etc.

[0025] In actual application, the inner core 103 is connected to the rod body 1 by screws. The inner core 103 is a hollow rectangle, and its size matches the inside of the rod body 1. A hole matching the connecting hole 102 is provided thereon. The two rod bodies 1 are butt-jointed through the inner core 103. The rod body 1 is connected to the reinforcing plate 104 outside and fixed by bolts to extend the length of the rod body 1. At the same time, the overall continuity and stability of the top of the frame are enhanced, while also playing a role of safety protection.

[0026] Example 3 like Figure 7~Figure 10 As shown, in this embodiment, the guide rail 2 is tubular and composed of a plurality of cavities 201, the cavities 201 are distributed parallel to the axial direction of the guide rail 2, and a side plate 202 is provided on the side of the guide rail 2. The side plates 202 are divided into two layers and arranged on both sides of the guide rail 2, and a track groove is formed between the side plates 202. The guide rail 2 is provided with equidistant through holes 203, and threaded holes 204 are provided between the cavities 201, and the through holes 203 are directly opposite to the threaded holes 204, so as to facilitate the installation and removal of screws.

[0027] Similar to Example 2, in this embodiment, the connection between the guide rails 2 is also achieved through the inner core 103. Since the guide rails are subjected to greater force, after the inner core 103 is inserted into the cavity 201, in order to ensure the connection strength, the front side of the inner core 103 is connected to the guide rail 2 and the reinforcement plate 104 by screws, and the side is fixed by the threaded hole 204 and the locking hole 205 on the side of the guide rail 2.

[0028] Example 4 like Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, the wall-mounted support 3 is a frame-like structure, connected to the building wall 15 by screws, and a plurality of plate-like connecting parts 301 are provided on the wall-mounted support 3, and a pair of rectangular tube beams 302 are connected through screw holes on the connecting parts 301, and the rectangular tube beams 302 are connected to the anti-falling device through the anti-falling fixed shaft 152. An unloading support 303 is connected to the top of the rectangular tube beam 302, and an anti-tilting device 304 is connected to the end of the rectangular tube beam 302.

[0029] Specifically, the rectangular tube beam 2 is rectangular, and dovetail grooves 3021 are provided on the upper and lower surfaces, so that it is not necessary to distinguish between the upper and lower parts during installation. A plurality of limit bars 3031 are provided on the unloading support 303 to match the dovetail grooves 3021. During installation, the limit bars 3031 are inserted into the dovetail grooves 3021, and the bolts on the unloading support 303 are tightened at the same time, so that the bolts and the surface of the dovetail grooves 3021 are locked to ensure that the rectangular tube beam 2 and the unloading support 303 do not slide relative to each other.

[0030] The unloading support 303 is movably connected with a screw rod 3033 through an ear plate 3032, and the screw rod 3033 is connected to a sleeve 305, and a support member 3051 is movably provided on the sleeve 305. After the climbing frame body is moved to a suitable position, the screw rod 3033 is swung to make the support member 3051 approach the guide rail 2, and the sleeve 305 is rotated to change the length of the extension of the support member 3051 until the groove on the surface of the support member 3051 is engaged with the nearest through hole 203, thereby supporting the climbing frame body.

[0031] Specifically, the anti-tilt device 304 includes an inner connecting member 3041 and a guide wheel connecting member 3042, both of which are L-shaped right-angle structures. A reinforcing triangle plate is provided at the end of the inner connecting member 3041, and an anti-slip wing plate 3043 is provided at the end of the guide wheel connecting member 3042. The anti-slip wing plate 3043 is higher than the surface of the guide wheel connecting member 3042 and is located in the same vertical direction as the guide wheel 3044. The inner connecting member 3041 and the guide wheel connecting member 3042 are connected by screws. The inner connecting member 3041 is connected to the rectangular tube beam 302, and a guide wheel 3044 is provided on the guide wheel connecting member 3042. The guide wheel 3044 is clamped between the side plates 202.

[0032] When in use, the anti-drop wing plate 3043 and the guide wheel 3044 are both stuck in the track formed by the side plate 202, and the climbing frame body moves up and down under the drive of the chain hoist 6. In the event of an unexpected failure of the guide wheel 3044, the anti-drop wing plate 3043 can ensure that the climbing frame body does not fall off the wall support 3, thereby ensuring the safety of the frame body.

[0033] Example 5 like Figure 16 to Figure 23As shown, in this embodiment, the scaffolding board 4 includes a first main keel board 401, a second main keel board 402 and a secondary keel board 403. The first main keel board 401 and the second main keel board 402 have L-shaped cross-sections and are arranged on both sides of the secondary keel board 403. A plurality of transverse keels 404 are also connected between the first main keel board 401 and the second main keel board 402. The transverse keels 404 are connected to the flap 13 through an L-reinforced connecting plate 405 to increase the lateral force strength. The side of the scaffolding board 404 is connected to the flap 13 through a hinge 4010, and a female buckle 409 that cooperates with the hinge 4010 is provided on the flap 13. Both the hinge 4010 and the female buckle 409 are provided with elliptical pin holes, which are connected together by pins. This structure provides redundancy for the flap 13 during the flipping process. The flap 13 seals the gap between the inner side of the scaffold frame and the building, which can effectively prevent personnel and materials on the floor from falling and provide safe and reliable protection for construction personnel inside and outside the frame.

[0034] In actual application, a first connection part 4031 and a second connection part 4032 are provided on both sides of the secondary keel plate 403, and the first connection part 4031 and the second connection part 4032 cooperate with each other; the first main keel plate 401 and the second main keel plate 402 are also provided with a first connection part 4031 and a second connection part 4032 respectively.

[0035] In practical applications, the first connection portion 4031 and the second connection portion 4032 are concave and convex portions that can cooperate with each other. The concave and convex portions can adopt a dovetail groove structure and are directly inlaid together when used.

[0036] Specifically, the first main keel plate 401 and the second main keel plate 402 are both provided with a bent keel 4012. The bent keel 4012 is perpendicular to the side plate 4011 and is installed at the edge of the side plate 4011, which improves the overall strength on the one hand and prevents the side plate 4011 from being cracked due to excessive tension on the other hand.

[0037] like Fig.17 As shown, the scaffolding board 4 also includes a sub-board 406, the cross section of the sub-board 406 is semi-open, and the side is connected to the first main keel board 401 or the second main keel board 402 through screw holes and screws, and a plurality of sub-keels 407 are arranged in the sub-board 6. The sub-board 406 is used as an extension of both sides of the scaffolding board 4 to reduce the gap between the scaffolding board 4 and the building, or to expand other connecting parts.

[0038] Example 6 like Fig.24 and 25As shown, in this embodiment, the upper and lower lifting frames 5 are frame-shaped, and the interior is divided into multiple cavities by a plurality of main ribs 502.

The ear plates 506 are connected by reinforcing blocks 507, and side ears 506 are provided on the ear plates 506.

[0039] When in use, a pin is inserted into the ear plate 504 for positioning the electric chain hoist 6 .

The wing plates 1111 are provided with grooves, which are used to improve the bending strength on the one hand and facilitate the positioning of the rivets 114 on the other hand.

[0041] like Fig.28 As shown, the structural length of the support truss 10 is shortened, and a connecting hole is added on the side to form an auxiliary support 11.

[0042] The horizontal support truss mainly bears the vertical load of the frame structure and transfers the load to the horizontal support structure of the vertical main frame. The horizontal support truss is arranged above the first layer of scaffolding, parallel to the facade of the building structure, and connected to the vertical main frame and the frame structure uprights. The lateral expansion of the support truss 10 can also be achieved through the inner insert 103 and the reinforcing plate 104.

[0043] Example 8 like Fig.29 As shown, in this embodiment, the lifting support 7 includes a pair of wedge plates 701, the wedge plates 701 are installed on the back plate 702, the back plate 702 is connected to the building wall 15, a reinforcing rod 703 is provided between the wedge plates 701, and a pin 704 is also movably connected between the wedge plates 701, and the pin 704 is connected through the chain hoist 6 to fix the position of the chain.

[0044] Example 9 like Fig.11 , Fig.30 , Fig.31 , Fig.32 , Fig.33As shown, the anti-fall device includes a star wheel 151, a first fixed plate 154 and a second fixed plate 155. The star wheel 151 rotates around the first fixed plate 154 and the second fixed plate 155. The star wheel 151 passes through the first fixed plate 154 and the second fixed plate 155 through a plurality of anti-fall fixed shafts 152 to fix the star wheel 151 on the rectangular tube beam 302; the star wheel 151 is provided with limiting teeth 1511 around it and is connected to the through holes 203 on the guide rail 2.

[0045] The inner ring of the star wheel 151 is provided with star wheel inner teeth 153, and the star wheel inner teeth 153 are a structure with a gradual height extension extending from the surface of the star wheel 151. The first fixed disk 154 and the second fixed disk 155 are provided with a guide groove 156, and the anti-fall block 157 is movably arranged in the guide groove 156. A tension spring positioning rod 1572 is provided between the first fixed disk 154 and the second fixed disk 155, one end of the tension spring 1571 is connected to the tension spring positioning rod 1572, and the other end is connected to the anti-fall block 157, and the tension spring positioning rod 1572 is located at the end of the guide groove 156.

[0046] The star wheel 151 is movably connected to the first trigger block 158 via a torsion spring 1581 and a torsion spring pin 1582. The torsion spring pin 1582 is also connected to a second trigger block 159. The second trigger block 159 is connected to the torsion spring 1581. One end of the first trigger block 158 is connected to the anti-fall block 157. The tail of the torsion spring 1582 is movably connected to the inner tooth 153 of the star wheel.

[0047] The anti-fall block 157 is provided with a slot 1575, and the tension spring 1571 is connected to the anti-fall block tension spring pin 1573 arranged in the slot 1575. The slot 1575 is provided with an anti-fall block positioning pin 1574, which is convenient for contacting and linking with the first trigger block 158.

[0048] Specifically, during use, the scaffolding is in motion, such as lifting, lowering, and sudden falling.

[0049] When the scaffolding frame is lifted, the guide rail 2 contacts the limit teeth 1511 on the anti-fall device, driving the star wheel 151 to rotate slowly, and the inner teeth 153 of the star wheel contact the second trigger block 159 during the rotation. When the second trigger block 159 is subjected to force, it rotates around the torsion spring pin 1582, and the anti-fall block 157 retracts under the action of the tension spring 1571, and the end of the anti-fall block 157 is separated from the inner teeth 153 of the star wheel, and the star wheel 151 can rotate freely. The star wheel 151 continues to rotate, and after the inner teeth 153 of the star wheel are separated from the second trigger block 159, the second trigger block 159 is subjected to the reverse torque of the torsion spring 1581 and returns to its original position around the torsion spring pin 1582, and the first trigger block 158 is in a stationary state. During this period, the star wheel 151 is in an unlocked state, and the frame is lifted normally.

[0050] When the frame is lowered, the anti-fall baffle of the guide rail drives the star wheel 151 to rotate in the opposite direction with the guide rail 2 on the scaffold frame ( Fig.31 Counterclockwise). The second trigger block 159 is squeezed by the star wheel anti-falling tooth 153 and rotates around the torsion spring pin 1582. The second trigger block 159 pushes the connecting pin 1583, and then the first trigger block 158 pushes the anti-falling block 157. After the anti-falling block 157 is stressed, it slides forward in the guide groove 156 in the fixed plate 154. The anti-falling block 157 simultaneously stretches the tension spring 1571, so that the end of the anti-falling block 157 slowly enters the area of ​​the adjacent anti-falling tooth 153. The upper surface of the end of the anti-falling block 157 maintains a small gap with the anti-falling tooth 153. When it continues to pass slowly, the second trigger block 159 and the anti-falling tooth 153 are not contacted and stressed. Under the action of the tension spring 1571, the anti-falling block 157 automatically pulls the anti-falling block 157 backward to its original position. During the return of the anti-falling block 157, the anti-falling block 157 and the first trigger block 158 are driven to return to their original positions around the torsion spring pin 1582.

[0051] When the frame suddenly falls during the lifting process, the anti-fall baffle on the guide rail drives the star wheel 151 to rotate rapidly in the opposite direction. The anti-fall tooth 153 drives the second trigger block 159 to rotate around the torsion spring pin 1582 under force, and the first trigger block 158 pushes the anti-fall block 157 to slide forward in the guide groove 156 in the fixed disk, and the rear tension spring 1571 of the slider is stretched. When the star wheel rotates rapidly, due to the inertia of the anti-fall block 157, the rear tension spring 1571 has not yet pulled the anti-fall block 157, and the inner teeth 153 of the star wheel quickly contact the end of the anti-fall block 157, and the anti-fall block 157 is stressed on the fixed disk, the star wheel 151 is stuck and stops rotating, and the frame stops falling, thereby preventing the frame from falling.

[0052] Example 10 like Fig.34 As shown, in this embodiment, the inclined tie rod 14 includes a pair of hollow tie rods 141, which are connected by threaded rods 142 and can adjust their lengths by flow, thereby controlling the verticality of the frame. In the specific connection, one of the hollow tie rods 141 is connected to the building wall 15 through a hinge, and the other is connected to the guide rail 2 through a hinge.
