Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a scaffold mounting structure and a mounting method thereof. BACKGROUND

[0002] The cantilevered scaffold is a kind of scaffold that uses the cantilever structure extending outward from the edge of the building structure to support the outer scaffold, and transfers all or part of the load of the scaffold to the building structure. The cantilever support structure of the cantilevered scaffold must have sufficient strength, stability and stiffness, and be able to transfer the load of the scaffold to the building structure.

[0003] In the related art, the mounting method of the cantilevered scaffold generally uses the cantilever beam or the cantilever frame as the base support of the scaffold, and sequentially sets the scaffold in sections from bottom to top on the cantilever beam. During the process of setting the scaffold upward, the connecting piece arranged on the upper building structure is connected with the scaffold, and then the outer facade of the cantilevered scaffold is provided with a scissors brace and other components.

[0004] The problem of the related art is that in order to ensure that the cantilever beam can provide stable support for the scaffold, it is necessary to ensure that the length of the cantilever beam is long enough so that the cantilever beam can be mostly laid and fixed on the surface of the building structure.

[0041] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0042] Example 1

[0043] This application discloses a scaffolding installation structure. (Refer to...) Figure 1 A scaffolding installation structure includes a scaffolding body 2 and a cantilever mechanism 1 that provides bottom foundation support for the scaffolding body 2. The cantilever mechanism 1 is installed on the building structure and extends outward to provide an installation position for the scaffolding body 2. Taking the building structure with the cantilever mechanism 1 as the lower building structure, when the scaffolding body 2 is installed on the cantilever mechanism 1 and extends upward, a wall tie assembly 3 is also provided on the upper building structure. The wall tie assembly 3 is connected to the portion of the scaffolding body 2 that extends upward through the upper building structure to improve the connection effect between the scaffolding body 2 and the building, thereby improving the stability of the scaffolding body 2.

[0044] Reference Figure 1 and Figure 2 The cantilever mechanism 1 includes a cantilever beam 11, one end of which is fixed to the lower building structure, and the other end extends horizontally outward from the building. A reinforcing component 13 is provided on the extension line of the cantilever beam 11 extending into the building. The reinforcing component 13 is fixed to the building surface. A steel rod 14 is provided between the reinforcing component 13 and the cantilever beam 11. The steel rod 14 is used to connect the cantilever beam 11 and the reinforcing component 13 to improve the connection effect between the cantilever beam 11 and the lower building structure.

[0045] Specifically, the reinforcing component 13 includes a fixed part 131 fixedly connected to the building surface, and a movable part 132 disposed on the fixed part 131. The movable part 132 is configured to be movable relative to the fixed part 131 along the extension direction of the steel rod 14. An elastic connector 33 is disposed between the fixed part 131 and the movable part 132. The relative position of the reinforcing component 13 and the steel rod 14 specifically satisfies the following condition: when the elastic connector 33 is not subjected to external force, the length of the steel rod 14 is slightly shorter than the distance from its connection point with the cantilever beam 11 to the movable part 132. With the above structure, after the steel rod 14 is fixed to the cantilever beam 11, because the steel rod 14 is relatively short, when the steel rod 14 is connected to the movable part 132, the movable part 132 will be displaced in the direction closer to the cantilever beam 11, thereby causing the elastic connector 33 to deform and apply a tensile force away from the cantilever beam 11 to the movable part 132. This tensile force is applied to the cantilever beam 11 through the steel rod 14, further improving the connection effect between the cantilever beam 11 and the lower building structure.

[0046] Furthermore, the steel rod 14 and the cantilever beam 11 are connected in the following manner. A fixing plate 6 perpendicular to the steel rod 14 is formed on the cantilever beam 11. The fixing plate 6 is preferably fixed to the cantilever beam 11 by welding. A through hole is provided on the fixing plate 6. One end of the steel rod 14 passes through the through hole and extends to the side of the fixing plate 6 away from the building and is connected to a first fastener 7. The first fastener 7 is tightened onto the steel rod 14 and abuts against the fixing plate 6 to achieve the connection and fixation of the steel rod 14 to the cantilever beam 11. Preferably, the first fastener 7 is a fastening nut, and a matching external thread is formed on the surface of the steel rod 14.

[0047] Furthermore, to buffer the tension exerted by the steel rod 14 on the fixed plate 6 and prevent the fixed plate 6 from deforming or being damaged, a pressure plate 8 is provided between the first fastener 7 and the fixed plate 6. When the elastic connector 33 applies tension to the steel rod 14 through the movable part 132, the tension first acts on the pressure plate 8 and is dispersed. The dispersed tension then acts on the fixed plate 6 through the pressure plate 8 to achieve buffering.

[0048] It is understandable that multiple fixing plates 6 can be provided, and the multiple fixing plates 6 are evenly distributed along the length of the cantilever beam 11 to connect the steel rod 14 to the cantilever beam 11 multiple times, thereby improving the connection stability.

[0049] Reference Figure 3The cantilever mechanism 1 also includes a fixing component 12, which is used to fix one end of the cantilever beam 11 extending into the lower building structure. The fixing component 12 specifically includes a U-shaped embedded part 121 pre-embedded in the lower building structure. The horizontal part of the U-shaped embedded part 121 is embedded in the lower building structure, and the vertical part extends upward to the top of the lower building structure. The two vertical parts are symmetrically distributed on both sides of the cantilever beam 11. The fixing assembly 12 also includes a pressure plate 122 and a second fastener 123. The pressure plate 122 has through holes for two vertical parts to pass through. One end of the cantilever beam 11 extends between the pressure plate 122, the building surface and the U-shaped embedded part 121, and the lower surface of the pressure plate 122 is in full contact with the upper surface of the cantilever beam 11. The second fastener 123 is tightened to the vertical part of the U-shaped embedded part 121 and abuts against the upper surface of the pressure plate 122 to fix the position of the pressure plate 122 and the cantilever beam 11, thereby realizing the connection between the cantilever beam 11 and the lower building structure.

[0050] Preferred, refer to Figure 4 The cantilever beam 11 adopts an I-beam structure. In the space formed on both sides of the cantilever beam 11 that is recessed towards the center, there are pads 9. The upper surface of the pads 9 abuts against the inner top wall of the cantilever beam 11, and the lower surface abuts against the inner bottom wall. The position of the pads 9 corresponds to the position of the fixing component 12. When the scaffold body 2 is installed on the part of the cantilever beam 11 that extends to the outside of the building, the scaffold body 2 applies downward pressure to one end of the cantilever beam 11, and the end of the cantilever beam 11 connected to the fixing component 12 is subjected to upward pressure. The pads 9 can evenly transmit this pressure to the cantilever beam 11 to prevent deformation at the connection between the cantilever beam 11 and the U-shaped embedded part 121 and the pressure plate 122.

[0051] Reference Figure 1 The wall tie assembly 3 includes an embedded pipe 31 that is pre-embedded in the upper building structure and extends vertically upwards, and a connector 32 that connects to the embedded pipe 31 and extends horizontally outwards from the building. The end of the connector 32 away from the embedded pipe 31 is connected to the scaffold body 2 extending thereto, thereby improving the connection effect between the scaffold body 2 and the building. The connection assembly also includes a fastener 33 that connects the embedded pipe 31 and the connector 32, and the scaffold body 2 and the connector 32. Both the connector 32 and the embedded pipe 31 are set as cylindrical tubular structures, and the fastener 33 adopts an existing component that can connect two perpendicular cylindrical pipes; its structure is not specifically limited here.

[0052] Example 2

[0053] Based on Embodiment 1, this embodiment further includes an anchor rod 4. One end of the anchor rod 4 is connected to the outer side of the superstructure, and it extends downwards at an angle to connect to the end of the cantilever beam 11 furthest from the building, thus forming a bracing structure to improve the connection stability of the cantilever beam 11. The connection method between the anchor rod 4 and the superstructure and the cantilever beam 11 adopts existing technology and will not be described in detail here.

[0054] Furthermore, a supporting rib 5 is provided on the outer side of the lower building structure. The supporting rib 5 includes a first connecting part 51, a second connecting part 52, and a stiffening part 53. The first connecting part 51 is in contact with and connected to the lower surface of the cantilever beam 11. The second connecting part 52 is fixed to the outer side of the lower building structure. The stiffening part 53 is disposed between the first connecting part 51 and the second connecting part 52. The first connecting part 51 and the second connecting part 52 are mutually perpendicular plate structures. The stiffening plate is a right-angled triangular plate. One right-angled side of the stiffening plate is welded and fixed to the first connecting part 51, and the other right-angled side is welded and fixed to the second connecting part 52.
