[0041] Please also read Figures 1 to 10 , the disc-type scaffolding provided by an embodiment of the present invention is described below.

[0042] See also Figures 1 to 5The embodiment of the present invention provides a disc-type scaffolding, including a frame-type support structure composed of a plurality of vertical poles 10, horizontal poles 20 and latches 30, and a plurality of protective components 40 arranged on the outer facade side of the frame-type support structure. The plurality of vertical poles 10 are arranged in a rectangular array, and each vertical pole 10 is provided with a plurality of connecting plates 11 at intervals along its own length direction. The connecting plates 11 are provided with a plurality of connecting holes 111 along its own circumferential direction. The connecting holes 111 penetrate the thickness direction of the connecting plates 11. The connecting holes 111 are usually long strip-shaped holes for the latches 30 to be inserted. The vertical pole 10 is also provided with a threaded section 12 between two upper and lower adjacent connecting plates 11. One end of the threaded section 12 is provided with a limiting portion 13 protruding from the outer circumferential surface of the vertical pole 10. The limiting portion 13 is annular, and the threaded section 12 is threadedly matched with a clamping nut 14. The plurality of horizontal poles 20 are respectively connected between two adjacent vertical poles 10, and the two ends of the horizontal poles 20 are respectively provided with connecting nuts 14. The connecting head 21 has an assembly groove for accommodating the connecting disk 11. The connecting head 21 is provided with a through connecting groove in the vertical direction, and the connecting groove corresponds to the connecting hole 111 up and down; a plurality of latches 30 are inserted into the connecting groove and the connecting hole 111 one by one, and are used to connect and fix the connecting disk 11 and the connecting head 21 as a whole; a plurality of protective components 40 are respectively arranged between two adjacent vertical poles 10, and the protective components 40 include a mesh frame 41 and a mesh sheet 42 covering the mesh frame 41, and connecting hooks 43 are respectively arranged on opposite sides of the mesh frame 41, and the connecting hooks 43 are sleeved on the outer periphery of the vertical pole 10 and are located between the limiting portion 13 and the clamping nut 14, and the clamping nut 14 applies a clamping force to the connecting hook 43.

[0043] Compared with the prior art, the disc-type scaffolding provided by the embodiment of the present invention has the following beneficial effects:

[0044] The disc-type scaffolding provided by the embodiment of the present invention comprises a vertical pole 10, a horizontal pole 20, a latch 30 and a protective assembly 40, wherein the vertical pole 10, the horizontal pole 20 and the latch 30 form a frame-type support structure, and the protective assembly 40 is detachably mounted on the facade side of the frame-type support structure. When construction needs to be stopped in windy weather, the protective assembly 40 can be removed to avoid damage to the disc-type scaffolding caused by excessive wind load on the protective assembly 40. Connecting hooks 43 are respectively provided on both sides of the net frame 41 of the protective assembly 40, and the connecting hooks 43 are used to connect with the vertical pole 10. The vertical pole 10 has a threaded section 12, and the threaded section 12 is provided with a clamping nut 14. The clamping nut 14 and the limiting portion 13 can clamp the connecting hook 43 firmly.

[0045] The embodiment of the present invention provides a hook-shaped connecting hook 43 on the protection component 40. When installing, it is only necessary to sleeve the connecting hook 43 on the upright pole 10 and lock and fix the connecting hook 43 by the clamping nut 14, which is convenient for installation and removal. Under the locking of the clamping nut 14 and the limiter 13, the connecting hook 43 will not fall off, and the fixation is firm and reliable, which greatly improves the installation and removal efficiency of the disc-type scaffolding protection component 40, and solves the problem of inconvenient and time-consuming disassembly of the mesh frame 41 on the disc-type scaffolding in the prior art.

[0046] In the embodiment of the present invention, the vertical pole 10 and the horizontal pole 20 are detachably connected by a latch 30. As required, an inclined pole can be further provided between two adjacent vertical poles 10, and the two ends of the inclined pole are respectively connected to the connecting plate 11. The inclined pole makes the overall structure of the disc-type scaffold more stable. The vertical pole 10 can be a single pole body, or can be obtained by plugging multiple pole bodies up and down. The horizontal pole 20 is shorter in length and is usually a single pole body. The two ends of the horizontal pole 20 are respectively connected to the two connecting plates 11, and the horizontal pole 20 and the connecting plate 11 are fixed together by the latch 30.

[0047] The protection component 40 includes a mesh frame 41, a mesh 42 and a connecting hook 43. The mesh frame 41 is generally in the shape of a square or approximately square frame structure, and is made of metal material (such as aluminum alloy, stainless steel), with high structural strength and strong anti-deformation ability. The mesh 42 covers the mesh frame 41, and the mesh 42 can be a metal mesh or a nylon mesh. The connecting hook 43 is fixedly connected to both sides of the mesh frame 41. In order to ensure a firm connection, a plurality of connecting hooks 43 are respectively provided on both sides of the mesh frame 41.

[0048] See also Figure 4 and Figure 5 In some possible embodiments, an elastic connector 44 is further provided between the connecting hook 43 and the mesh frame 41. When the connecting hook 43 is sleeved on the vertical pole 10, the elastic connector 44 is in a tension state.

[0049] In this embodiment, an elastic connector 44 such as a rubber rod or a spring is provided between the connecting hook 43 and the mesh frame 41, and the elastic connector 44 is in a tension state after installation. Such a setting has the following two effects: on the one hand, since the elastic connector 44 has a certain elastic deformation amount, it can make up for a certain size error. When there is an error between the spacing between the two vertical poles 10 and the design size, the elastic deformation amount of the elastic connector 44 can make up for the error, ensuring that the protective component 40 is smoothly installed between the two vertical poles 10. On the other hand, the elastic connector 44 of the installed protective component 40 is in a tension state. When encountering a large wind load, the wind force on the mesh frame 41 and the mesh 42 can be absorbed and offset by the telescopic deformation of the elastic deformation member, which can improve the wind resistance of the protective component 40.

[0050] The latch 30 is a wedge-shaped member that is thick at the top and thin at the bottom. Since the latch 30 is small in size, it is easy to be lost after the disc-type scaffolding is dismantled.

[0051] To solve the problem that the latch 30 is easily lost, please refer to Figure 3 and Figure 6 In some possible embodiments, the assembly groove separates the connector 21 into a first connection portion 211 located above the connection disk 11 and a second connection portion 212 located below the connection disk 11; the first connection portion 211 is provided with a through first slot 2111 along the up-down direction, and the second connection portion 212 is provided with a through second slot 2121 along the up-down direction, the first slot 2111 and the second slot 2121 together form a connection groove, and the hole size of the second slot 2121 is larger than the hole size of the first slot 2111; the lower end of the latch 30 has a limiting protrusion 31, and when the latch 30 is lifted from bottom to top, the limiting protrusion 31 can pass through the second slot 2121 and can be stopped and limited by the first slot 2111.

[0052] In this embodiment, a limiting protrusion 31 is provided at the lower end of the plug 30. The limiting protrusion 31 can be a rivet, screw or other structure protruding from the side wall of the plug 30. After the plug 30 is inserted into the connection slot on the connector 21, the limiting protrusion 31 is obtained by installing a rivet, screw or welding a protrusion at the lower end of the plug 30. In this way, when the plug 30 is pulled out upward, due to the limitation of the limiting protrusion 31, the plug 30 cannot be disengaged from the first slot 2111 of the first connecting portion 211.

[0053] It is understandable that due to the existence of the limiting protrusion 31, when the limiting protrusion 31 is formed, the latch 30 and the cross bar 20 become a combination, and during the subsequent installation and removal of the disc-type scaffold, the latch 30 and the cross bar 20 will not be separated. In this way, the latch 30 is permanently limited on the connecting head 21 of the cross bar 20, which plays a role in preventing loss.

[0054] It should be noted that when designing the shape of the connector 21 and the latch 30, care should be taken to design the assembly groove to be larger in height so that the connection plate 11 has a certain installation margin in the assembly groove to prevent the lower end of the latch 30 from interfering with the connection plate 11 and affecting the connection between the connection plate 11 and the cross bar 20.

[0055] After the latch 30 is inserted into the connection slot and the connection hole 111, it is necessary to use a hammer to hammer the latch 30 into a certain depth from the top so that the latch 30 firmly wedges the connector 21 and the connection plate 11 together to prevent the crossbar 20 and the vertical bar 10 from shaking. When dismantling the disc-type scaffolding, it is necessary to hammer the latch 30 out from the bottom. Figure 1 and Figure 2As shown, a connection plate 11 of a vertical pole 10 in the middle position can be provided with three or even four cross bars 20 at most, that is, 3-4 latches 30 can be provided on a connection plate 11. When the disc-type scaffolding also includes diagonal bars, the diagonal bars also need to be installed together with the connection plate 11 through the latches 30, so that a connection plate 11 can be provided with 6-8 latches 30 at most. During installation and disassembly, the latches 30 need to be frequently hammered in and out one by one, which is labor-intensive and inefficient.

[0056] To solve the above problems, see Figure 3 and Figure 6 In some possible embodiments, a limiting groove 32 is provided at the upper end of the latch 30 on a side away from the vertical pole 10, and a hoop 50 is sleeved on the vertical pole 10. When a plurality of latches 30 are provided on the connecting plate 11 along its own circumferential direction, the hoop 50 is sleeved in the limiting grooves 32 of the plurality of latches 30.

[0057] In this embodiment, the hoop 50 can be a split structure, which is obtained by combining two semi-annular components, or it can be an integrated annular component in the embodiment described below. Figure 3 As shown, the sleeve is arranged in the limiting grooves 32 of multiple latches 30. On the one hand, during installation and disassembly, the hoop 50 can be hammered downward or upward to drive multiple latches 30 to move downward or upward at the same time, which improves the construction efficiency compared with hammering the latches 30 one by one. On the other hand, the setting of the hoop 50 also helps the construction personnel to intuitively understand whether the multiple latches 30 are at the same height. When the height of one of the latches 30 is inconsistent with the other latches 30, the hoop 50 cannot be installed smoothly because the limiting grooves 32 of the multiple latches 30 are misaligned with each other at this time, so as to avoid the situation that the latches are not inserted tightly. On the other hand, when the disc-type scaffolding is installed, the hoop 50 can tighten the multiple latches 30 together at the same time, and the latches 30 are not easy to loosen. It also helps to prevent the disc-type scaffolding from shaking due to the loosening of the latches 30, so that the safety of the product is guaranteed.

[0058] See also Figure 3 and Figure 6 In some possible embodiments, the hoop 50 is a rigid ring, and the inner wall of the hoop 50 is provided with a plurality of avoidance grooves 51 at equal intervals along its circumferential direction, and the avoidance grooves 51 are used for the top end of the latch 30 to pass through.

[0059] In this embodiment, the hoop 50 is an integral rigid component, which can be made of steel, cast iron and other materials, and is durable and not easy to damage. When installing the hoop 50, align the plurality of avoidance grooves 51 with the plurality of latches 30, and then install the hoop 50 downward into the limiting grooves 32 of the latches 30, and then rotate the hoop 50 slightly to make the avoidance grooves 51 and the latches 30 misaligned with each other.

[0060] See also Figure 1 , Figures 7 to 10 In some possible embodiments, the disc-type scaffolding further includes a plurality of pedal assemblies 60, which are detachably arranged between adjacent cross bars 20 for storing materials and for construction workers to move around.

[0061] See also Figure 7 , Figure 8 , Fig. 9 and Fig.10 In some possible embodiments, the pedal assembly 60 includes a plurality of pedal units 61 arranged in sequence along the length direction of the cross bar 20, a slot 611 is provided on one side of the pedal unit 61, and an insertion rod 612 is provided on the other side, the slot 611 of the previous pedal unit 61 is plugged into the insertion rod 612 of the next pedal unit 61, and connecting hangers 615 are respectively provided at both ends of the pedal unit 61 adjacent to the cross bar 20, and the connecting hangers 615 are hook-shaped and used to be hung above the cross bar 20.

[0062] In this embodiment, the pedal assembly 60 is formed by splicing a plurality of pedal units 61. Each pedal unit 61 is small in size and light in weight, and is easy to install. The pedal unit 61 is a rectangular plate-shaped component. Both ends of the pedal unit 61 are hung on the crossbars 20 on both sides by connecting hangers 615. The structure is simple and easy to install.

[0063] The pedal unit 61 may be hollowed out or made of a solid metal plate. In order to improve the anti-skid effect, an anti-skid layer may be provided on the upper surface of the pedal unit 61 or anti-skid patterns may be processed.

[0064] See also Figure 7 , Figure 8 , Fig. 9 and Fig.10 In some possible embodiments, the pedal unit 61 has a accommodating cavity, and the pedal assembly 60 also includes a plurality of locks 62, which are respectively arranged on the pedal unit 61. The locks 62 include a locking block 621 and a transmission mechanism. The locking block 621 is slidably arranged on the insertion rod 612 along the diameter direction of the insertion rod 612. The locking block 621 has a locked state and an unlocked state. When in the locked state, the locking block 621 extends out of the insertion rod 612. When in the unlocked state, the locking block 621 is accommodated in the insertion rod 612. The interior of the slot 611 has a locking groove that is plugged in and adapted to the locking block 621. The transmission mechanism is arranged in the accommodating cavity, and is used to drive the locking block 621 to switch between the locked state and the unlocked state.

[0065] In this embodiment, two adjacent pedal units 61 are connected as a whole via a lock 62. After locking, no gap will be generated between the adjacent pedal units 61. The integrated pedal assembly 60 is also not prone to vibration or shaking, which can improve the stability of the pedal assembly 60. Construction workers can walk on the pedal assembly 60 more smoothly and safely.

[0066] See also Figure 7 , Figure 8 , Fig. 9 and Fig.10 In some possible embodiments, the transmission mechanism includes a rack 622 and a gear 623. The rack 622 is arranged in the accommodating cavity along the sliding direction of the locking block 621, and the rack 622 is connected to the portion of the locking block 621 extending into the accommodating cavity; the gear 623 is arranged in the accommodating cavity and meshes with the rack 622 for transmission. The gear 623 rotates forward or backward to drive the locking block 621 to extend or retract from the locking rod, thereby achieving locking or unlocking.

[0067] See also Figure 8 , Fig. 9 and Fig.10 In some possible embodiments, a lock core 613 is provided on the upper surface of the pedal unit 61, and the lock core 613 is coaxially connected to the gear 623. A protective cover 614 is provided on the upper surface of the pedal unit 61, and the protective cover 614 has a protective state covering the top of the lock core 613 and an open state removed from the top of the lock core 613. The lock core 613 is driven by a key, and a special key manager is responsible for keeping it. In order to prevent the lock core 613 from being blocked by impurities such as mud, a protective cover 614 is provided on the lock core 613.

[0068] During daily use, the protective cover 614 is in a protective state, and the cover is arranged above the lock core 613. Only when the buckle type scaffold needs to be dismantled, the protective cover 614 needs to be opened, and the lock core 613 is driven to rotate by the key, thereby driving the two lock blocks 621 to be retracted into the lock rod, so that the pedal units 61 are separated from each other.
