Description

Technical Field

[0001] This invention relates to the field of scaffolding technology, and more specifically to a modular facade scaffolding. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It is classified into external scaffolding and internal scaffolding based on its location. External scaffolding is commonly erected on the exterior facade of a building under construction, serving to facilitate construction and protect the building. Existing facade scaffolding generally meets daily needs, but some shortcomings still require improvement.

[0003] Patent document CN104790641A, published on July 22, 2015, discloses a tenon-and-mortise type scaffolding diagonal bracing system, including short screw-connected diagonal bracing and long screw-connected diagonal bracing intersecting with it. The long screw-connected diagonal bracing is located outside the short screw-connected diagonal bracing. Both the upper and lower ends of the short screw-connected diagonal bracing are penetrated by short screws perpendicular to them. The inner end of the short screw is fixed with a tenon I, which is fitted into a corresponding central mortise socket. The outer end of the short screw is connected with a locking nut I. Both the upper and lower ends of the long screw-connected diagonal bracing are penetrated by long screws perpendicular to them. The inner end of the long screw is fixed with a tenon II, which is fitted into a corresponding central mortise socket. The outer end of the long screw is connected with a locking nut II. A limit nut is connected to the middle of the long screw. The short screw-connected diagonal bracing and the long screw-connected diagonal bracing are connected by a central connecting screw at the intersection. This invention can be used in conjunction with mortise and tenon scaffolding to improve the load-bearing capacity and safety of the entire scaffolding and perfect the mortise and tenon scaffolding system.

[0004] The existing facade scaffolding described in the aforementioned patent typically includes three types of poles that act in three directions: uprights for providing height support, horizontal bars for forming a work platform, and diagonal bars for reinforcing protection. The diagonal bars are connected to the platform, and existing technologies often use traditional fastener connections, resulting in low efficiency in the erection and dismantling of the diagonal bars. Therefore, there is an urgent need for a modular facade scaffolding to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a modular facade scaffolding to address the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A modular facade scaffolding includes multiple parallel uprights and horizontal bars connecting adjacent uprights. Diagonal reinforcing bars are arranged on the uprights. The scaffolding also includes: a connecting seat assembly disposed on the uprights to provide a connection node; bolts threaded to the connection nodes, with matching through holes on the diagonal reinforcing bars; and a self-locking assembly disposed at the end of the bolts to limit the movement of the diagonal reinforcing bars connected to the bolts.

[0008] Preferably, the connecting seat assembly includes two support plates, which are symmetrically arranged and fixedly connected to opposite sides of the upright. A first nut is fixedly connected between the two support plates, and a bolt can be threadedly connected to the first nut.

[0009] Preferably, the connecting seat assembly includes two half-hoops, which are symmetrically arranged and connected by bolt fasteners to be sleeved on the upright. A second nut is fixedly provided on the half-hoops, and the bolt can be threadedly connected to the second nut.

[0010] Preferably, the upright is provided with an adjustment hole, and one end of the bolt that is screwed to the second nut passes through the adjustment hole.

[0011] Preferably, the self-locking assembly includes a receiving groove on the bolt, a latch hinged in the receiving groove, a sliding groove on the latch, and a sliding pin fixedly disposed in the receiving groove and movably connected to the sliding groove. When the bolt is tightened at the connection node, the latch has a first position where it is fully retracted into the receiving groove and a second position where its free end swings downward and extends out of the receiving groove.

[0012] Preferably, the bolt is provided with an anti-torsion component that is linked to the latch. When the latch is subjected to the tensioning thrust of the inclined reinforcing rod, the anti-torsion component can extend into the adjustment hole to restrict the rotation of the bolt.

[0013] Preferably, the anti-torsion component includes a locking block movably disposed at one end of the bolt corresponding to the adjustment hole and a movable part movably disposed on the side wall of the bolt. The locking block is provided with a first linkage groove, and a linkage column fixedly connected to one end of the movable part is movably connected in the first linkage groove. A linkage shaft is fixedly disposed at the other end of the movable part, and the linkage shaft movably extends into the storage groove. The latch is provided with a second linkage groove movably connected to the linkage shaft.

[0014] Preferably, the side wall of the bolt is provided with a movable groove that matches the movable part, and the movable part moves in the movable groove with damping.

[0015] Preferably, the upper end of the upright is provided with an extension, and the lower end is provided with a sleeve portion that matches the extension.

[0016] Preferably, the upper side wall of the upright is provided with a toe-shaped member.

[0017] In the above technical solution, the beneficial effects of the present invention are:

[0018] This modular facade scaffolding, by incorporating a self-locking component, allows the diagonal reinforcing bars to be connected to the bolts via through holes after the bolts are first connected to the connection nodes formed by the connecting seat assembly on the uprights. The self-locking component then automatically limits the outer side of the diagonal reinforcing bars, thereby facilitating the fixing and disassembly of the diagonal reinforcing bars and improving the efficiency of scaffolding erection and dismantling.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0032] Please see Figure 1-7 The present invention provides a modular facade scaffolding, comprising a plurality of parallel and spaced uprights 1 and a crossbar 2 connecting two adjacent uprights 1. The uprights 1 are provided with diagonal reinforcing bars 3. The scaffolding also includes: a connecting seat assembly, which is disposed on the uprights 1 to provide a connection node; a bolt 4, which is threadedly connected to the connection node, and the diagonal reinforcing bars 3 are provided with matching through holes; and a self-locking assembly, which is disposed at the end of the bolt 4 to limit the diagonal reinforcing bars 3 connected to the bolt 4.

[0033] Specifically, uprights 1 are usually arranged in pairs, one in each direction outside the building. Multiple sets of uprights 1 are arranged at equal intervals along the horizontal direction parallel to the building facade. In addition, uprights 1 can be erected layer by layer upwards. Horizontal bars 2 are used to connect two uprights 1 in the same group and are set close to the upper end of uprights 1. Horizontal bars 2 are perpendicularly connected to uprights 1, and a triangular reinforcing plate is fixed at the lower angle of the connection. Diagonal reinforcing bars 3 are arranged at an angle to connect multiple sets of uprights 1. The height distribution of the connecting seat assembly on multiple adjacent uprights 1 varies in a stepped manner, so that the multiple connecting nodes are connected and set in the same diagonal line, which matches the erection position of the diagonal reinforcing rod 3; one end of the bolt 4 is provided with an external thread, and the other end is a cylindrical surface. The outer diameter of the cylindrical end is not less than the outer diameter of the threaded end. Thus, when the bolt 4 is tightened with the connecting node, the overhang length and angle position can be fixed; the diagonal reinforcing rod 3 is connected to the bolt 4 by a through hole and is set close to the upright 1. The other side of the diagonal reinforcing rod 3 is limited by the self-locking component; the self-locking component can realize self-locking and unlocking at one time, which is convenient for assembly and disassembly. In practical use, this technical solution first connects the bolt 4 to the connection node formed on the upright 1 by the connecting seat assembly. Then, the diagonal reinforcing bar 3 is connected to the bolt 4 through the through hole. When the diagonal reinforcing bar 3 is close to the upright 1, the self-locking assembly automatically limits the outer side of the diagonal reinforcing bar 3, which facilitates the fixing of the diagonal reinforcing bar 3. When disassembling, the self-locking assembly can be unlocked in one operation, and then the diagonal reinforcing bar 3 can be quickly disassembled, thereby improving the efficiency of scaffolding erection and dismantling.

[0034] Compared with the prior art, the modular facade scaffolding proposed in this embodiment of the invention, by setting a self-locking component, allows the diagonal reinforcing bar 3 to be connected to the bolt 4 by means of through holes after the bolt 4 is first connected to the connection node formed on the upright 1 by the connecting seat assembly. Then the self-locking component automatically limits the outer side of the diagonal reinforcing bar 3, thereby facilitating the fixing and disassembly of the diagonal reinforcing bar 3 and improving the efficiency of scaffolding erection and disassembly.

[0035] As a preferred technical solution of this embodiment, the connecting seat assembly includes two support plates 5, which are symmetrically arranged and fixedly connected to opposite sides of the upright 1. A first nut 6 is fixedly connected between the two support plates 5, and a bolt 4 can be threadedly connected to the first nut 6. Specifically, the support plate 5 is provided with an opening, and the first nut 6 forms the above-mentioned connecting node. The axis of the first nut 6 is perpendicular to the direction of the upright 1. The upright 1 is provided with a circular hole corresponding to the first nut 6, and one end of the bolt 4, which is tightened with the first nut 6, passes through the circular hole to fix the support plate 5 relative to the upright 1.

[0036] In practical use, multiple through holes are evenly distributed at both ends and in the middle of the diagonal reinforcing rod 3. The through holes at both ends of the diagonal reinforcing rod 3 can be fixed by the connecting components described in the above embodiment, and further reinforced by steel wire binding through the openings on the support plate 5. The middle part of the diagonal reinforcing rod 3 mainly serves as a limit to resist the outward tension force of the scaffold. In addition, the erection accuracy of scaffolding is generally low. After fixing the positions of the two ends of the diagonal reinforcing rod 3, the correspondence between the through hole in the middle position and the bolt 4 is prone to deviation. The following embodiment is proposed to solve this problem.

[0037] In another embodiment of the present invention, the connecting seat assembly includes two half-hoops 7, which are symmetrically arranged and connected by bolts to be fitted onto the upright 1. A second nut 8 is fixedly provided on the half-hoops 7, and the bolt 4 can be threadedly connected to the second nut 8. Specifically, the half-hoops 7 are arc-shaped and bent into a sheet shape at both ends. The two half-hoops 7 can be connected by two sets of bolts at both ends, or they can be hinged to each other at one end and connected by a set of bolts at the other end. The two connected half-hoops 7 are fitted onto the upright 1 and can be moved up and down along the outer wall of the upright 1 to adjust their height. The second nut 8 forms the above-mentioned connecting node, and the axis of the second nut 8 is perpendicular to the direction of the upright 1. Since the height of the half-hoops 7 is adjustable, the height of the bolt 4 in the middle part of the corresponding diagonal reinforcing bar 3 can be freely adjusted to adapt to the corresponding through hole. After the bolt 4 in this part is connected to the through hole, it is then tightened to be held and fixed onto the upright 1 by the connection of the two half-hoops 7.

[0038] As a preferred technical solution in this embodiment, the upright 1 is provided with an adjustment hole 9, and one end of the bolt 4, which is screwed and connected to the second nut 8, passes through the adjustment hole 9. Specifically, the setting of the adjustment hole 9 and the setting of the bolt 4 passing through the adjustment hole 9 can pre-limit the adjustable height range of the bolt 4 under the movable function of the two half-hoops 7 fitted on the upright 1, so as to facilitate the quick matching of this part of the bolt 4 with the through hole on the inclined reinforcing bar 3 during actual erection.

[0039] As a preferred embodiment of the above technical solution, the self-locking assembly includes a receiving groove 10 provided on the bolt 4, a latch 11 hinged in the receiving groove 10, a sliding groove 12 provided on the latch 11, and a sliding pin 13 fixedly provided in the receiving groove 10 and movably connected to the sliding groove 12. When the bolt 4 is tightened at the connection node, the latch 11 has a first position where it is fully retracted into the receiving groove 10 and a second position where its free end swings downward and extends out of the receiving groove 10. Specifically, the receiving... A groove 10 is formed at one end of the cylindrical surface of the bolt 4, creating a U-shape. A latch 11 is plate-shaped and embedded in the receiving groove 10. The hinged end of the latch 11 is close to the U-shaped opening of the receiving groove 10, while the free end of the latch 11 faces the inside of the receiving groove 10. The sliding groove 12 and sliding pin 13 limit the rotation angle of the latch 11. When the bolt 4 is tightened at the connection node, the latch 11 can swing up and down, and the angle of this swing is preferably no greater than [missing value]. When the angle exceeds 25°, the latch 11 is fully retracted into the storage groove 10 in the first position, which does not affect the bolt 4 passing through the through hole. In the second position, the free end of the latch 11 swings down and extends out of the storage groove 10 under its own weight, thus limiting it to the outside of the inclined reinforcing rod 3 already connected to the bolt 4. In actual use, when the inclined reinforcing rod 3 is inserted into the bolt 4 through the through hole from the cantilever end, it just presses from the hinge end of the latch 11 towards the free end. Thus, the latch 11 can automatically retract into the storage groove 10 to be in the first position, which does not affect the bolt 4 passing through the through hole. After the inclined reinforcing rod 3 passes through the latch 11, the latch 11 automatically swings down under its own weight to reach the second position, which serves to limit the inclined reinforcing rod 3. Afterwards, when disassembling the inclined reinforcing rod 3, the latch 11 is first actively pushed upward to retract back into the storage groove 10, that is, back to the first position. Then the inclined reinforcing rod 3 can be disassembled along the outer wall of the bolt 4.

[0040] In another embodiment of the present invention, the bolt 4 is provided with an anti-torsion component that is linked to the locking buckle 11. When the locking buckle 11 is subjected to the tensioning force of the inclined reinforcing rod 3, the anti-torsion component can extend into the adjusting hole 9 to restrict the rotation of the bolt 4. Specifically, the bolt 4 is threaded to the connection node. When it is subjected to the axial thrust applied by the tensioning force of the inclined reinforcing rod 3, it may be forced to rotate. This embodiment addresses this issue. The anti-torsion component can restrict the rotation of the bolt 4 relative to the adjusting hole 9, that is, restrict the rotation of the bolt 4. Furthermore, by linking with the locking buckle 11, when the inclined reinforcing rod 3 is pushed outward by the tensioning force, the locking buckle 11 can move further to passively activate the anti-torsion component to restrict the rotation of the bolt 4, thereby preventing the bolt 4 from loosening and failing.

[0041] As a preferred embodiment, the anti-torsion assembly includes a locking block 14 movably disposed at one end of the bolt 4 corresponding to the adjustment hole 9, and a movable member 15 movably disposed on the side wall of the bolt 4. The locking block 14 is provided with a first linkage groove 16, and a linkage post 17 fixedly connected to one end of the movable member 15 is movably connected within the first linkage groove 16. A linkage shaft 18 is fixedly disposed at the other end of the movable member 15, and the linkage shaft 18 movably extends into the receiving groove 10. The latch 11 is provided with a second linkage groove 19 movably connected to the linkage shaft 18. Specifically, the bolt 4 is provided with a through groove matching the locking block 14, and the through groove... The storage slots 10 are co-located. When the bolt 4 is tightened at the connection node, the locking block 14 moves up and down within the through slot. The movable part 15 moves axially along the bolt 4. The first linkage slot 16 is inclined and its upper end is closer to the storage slot 10. When the movable part 15 moves away from the storage slot 10, it moves up through the first linkage slot 16 and the linkage column 17, and the locking block 14 moves up. Conversely, it moves down. The linkage shaft 18 can move with the movable part 15. The sliding pin 13 moves along the sliding slot 12 in an arc shape, and the center of the arc corresponds to the linkage shaft 18 at the end of the second linkage slot 19 away from the sliding slot 12. In actual use, during the initial installation of bolt 4, the movable part 15 does not move, and the locking block 14 does not extend out of the outer wall of bolt 4. Therefore, bolt 4 can be normally screwed onto the connection node, and one end with the locking block 14 extends into the adjustment hole 9. After bolt 4 is tightened, the locking buckle 11 can extend its free end out of the storage groove 10 under its own weight, that is, the locking buckle 11 is in the second position. At this time, the linkage shaft 18 is at the end of the second linkage groove 19 away from the sliding groove 12, and the locking buckle 11 rotates around the linkage shaft 18. The linkage shaft 18 serves as the rotation axis of the locking buckle 11, and the sliding pin 13 slides along the sliding groove 12 to reach the upper end of the sliding groove 12. Then, the inclined reinforcing rod 3 is installed on bolt 4, and the locking buckle 11 can be in the second position to limit the inclined reinforcing rod 3. When the inclined reinforcing rod 3 is installed, the locking buckle 11 can be in the second position to limit the inclined reinforcing rod 3. When the strong rod 3 pushes the latch 11 outward further with the tension force it receives, the free end of the latch 11 is forced downward. At this time, if the latch 11 continues to rotate around the linkage shaft 18 as the axis of rotation, the free end cannot rotate downward. Therefore, the latch 11 begins to rotate around the sliding pin 13 with the upper end of the sliding groove 12. The second linkage groove 19, which is in an inclined state at this time, forces the linkage shaft 18 to move. The linkage shaft 18 then drives the movable part 15 to move away from the storage groove 10. Then, through the first linkage groove 16 and the linkage column 17, the linkage block 14 rises to extend out of the outer wall of the bolt part 4 and is in the adjustment hole 9, thereby limiting the bolt part 4 from rotating at a large angle relative to the adjustment hole 9. That is, the function of preventing the bolt part 4 from loosening is passively triggered. At this time, the position of the latch 11 can be the third position.

[0042] As a preferred technical solution in this embodiment, the side wall of the bolt member 4 is provided with a movable groove 20 that matches the movable member 15. The movable member 15 moves in the movable groove 20 with damping. Specifically, the damped movement of the movable member 15 in the movable groove 20 makes the latch 11 rotate only with the linkage shaft 18 when it is not subjected to external force and is only subjected to its own weight. When the latch 11 is subjected to the thrust of the inclined reinforcing rod 3, the latch 11 rotates with the sliding pin 13 as the axis of rotation, thus forcing the linkage shaft 18 to move.

[0043] As a preferred technical solution of the above embodiments, the upper end of the upright 1 is provided with an extension 21, and the lower end is provided with a sleeve 22 that matches the extension 21. Specifically, the extension 21 and the sleeve 22 are provided to satisfy the upward extension of the upright 1.

[0044] As a preferred technical solution of the above embodiments, a toe-shaped member 23 is provided on the upper side wall of the upright 1. Specifically, the toe-shaped member 23 is used to limit and fix the platform forming components such as the treads erected on the crossbar 2.

[0045] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
