Description

Technical Field

[0001] The utility model relates to the field of scaffold installation, in particular to a support structure for an attached lifting scaffold at a high overhead floor. Background Art

[0002] Attached lifting scaffolding refers to a scaffolding that is erected to a certain height, attached to a building structure through an attachment support device, lifted layer by layer along with the building structure by relying on its own lifting mechanism, and has the functions of safety protection, anti-overturning, anti-falling and synchronous control. Lifting scaffolding mainly comprises wall-attached supports, climbing guide rails and a climbing scaffold main body, wherein the climbing guide rails are installed on one side of the wall-attached supports, and the climbing scaffold main body is installed on the outer side of the climbing guide rails. For a climbing scaffold with a suspended height lower than 5m, the climbing guide rail can only be supported by the wall-attached support fixed on the main structure, while for some high-rise buildings, the suspended floor is often larger than 5m, and some heights reach ten meters. For such high-rise buildings with high suspended floors, the conventional climbing scaffold support structure can no longer meet the support requirements.

[0003] At present, in order to achieve effective support for the climbing scaffold of high overhead floor buildings, a Chinese patent with application number 2018217169059 discloses an attached lifting scaffold support device for high overhead floor structures, which comprises a steel wire rope pulling embedded part, a steel column embedded part and a rigid tie rod embedded part respectively pre-embedded in a building floor, a steel column is vertically welded on the steel column embedded part, one end of the steel wire rope is fixedly connected with the steel wire rope pulling embedded part, and the other end is pulled and fixed on the steel column, one end of the steel pipe is fixedly connected with the steel column embedded part, and the other end is fixedly supported on the steel column. The support structure fixedly installs the steel column on the building floor at the high overhead floor, fixes the wall-attached lifting scaffold support on the steel column, and provides a support point for the attached lifting scaffold through the wall-attached lifting scaffold support, which effectively solves the problem that there is no place for the support point of the supporting column of the attached lifting scaffold to bear force due to the large spacing between horizontal members of the high overhead floor structure. When the above support device is installed, the outer side of the column needs to be flush with the outer end face of the floor slab, so as to ensure that after the wall-attached support is installed, it is placed outside the floor slab. For a structural layer with side beams poured on the floor slab, if the above support structure is directly used, the wall-attached support will be placed inside the side beam after installation, and cannot extend out of the floor to connect with the climbing guide rail. Summary of the Invention

[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a support structure for an attached lifting scaffold at a high overhead floor, and solve the problem that the existing support for lifting scaffolds is not applicable to structural layers provided with side beams.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A support structure for an elevated, attached, lifting scaffold includes columns fixed to the floor slab and at least one wall-mounted support installed on the outside of the columns. An mounting base is provided between the wall-mounted support and the columns. The mounting base is a square frame welded from multiple square steel bars, and its thickness corresponds to the thickness of the edge beams on the floor slab. The wall-mounted support, mounting base, and columns are fixedly connected by at least two double-ended bolts and fastening nuts at both ends of the double-ended bolts. A grounding beam is fixedly connected to the lower end of the columns and is placed on the floor slab, fixedly connected to the floor slab by grounding bolts and locking nuts. At least one diagonal brace is provided inside the columns, with its upper and lower ends connected to the columns and the grounding beam, respectively. By adding a mounting base between the column and the wall-mounted support, and connecting and fixing the column, mounting base, and wall-mounted support with double-ended bolts and fastening nuts, the inner end of the wall-mounted support is aligned with the outer surface of the edge beam and the same mounting surface as other wall-mounted supports fixed to the exterior wall, effectively ensuring the installation of the climbing guide rail. Simultaneously, the lower end of the column connects to a grounding beam, which is fixed to the floor slab with grounding bolts, making installation and disassembly convenient and ensuring high structural stability.

[0007] Furthermore, the column includes two vertically arranged left square tubes and two right square tubes. Multiple horizontally arranged connecting square tubes are spaced between the left and right square tubes. The left, connecting, and right square tubes are connected by tie rods that pass through them sequentially and are then secured with threaded nuts. In this way, the column is composed of multiple square tubes connected and fixed by tie rods, ensuring that the column's strength meets the set requirements. Moreover, the square tubes and connecting components are all conventional building materials, eliminating the need for custom-made columns.

[0008] Furthermore, the grounding beam is the same width as the column and is composed of multiple rectangular tubes of equal length. Multiple connecting through holes are evenly spaced along the length of each left and right square tube and the rectangular tubes. A connecting plate is provided on both sides of the column, tightly attached to the side ends of the column and the grounding beam. The connecting plates are connected and fixed to the column and the grounding beam using fasteners. In this way, the grounding beam, composed of multiple rectangular tubes, is fixed to the column via connecting plates, and the rectangular tubes of the grounding beam are fixed to the square tubes of the column via fasteners and connecting plates, making installation and disassembly relatively convenient.

[0009] Furthermore, a diagonal brace mounting plate is provided on the opposite side of the mounting base, closely attached to the inner side of the column. Two spaced-apart first lugs are vertically fixed on the diagonal brace mounting plate, and two second lugs are provided on two rectangular tubes of the grounding beam. The upper and lower ends of the diagonal brace are respectively fixedly connected to the first and second lugs via connectors. In this way, the first lugs on the diagonal brace mounting plate correspond to the second lugs on the grounding beam, facilitating the connection and fixation of the diagonal brace.

[0010] Furthermore, a connecting lug is welded and fixed on both sides of the diagonal brace mounting plate. A pre-embedded support is provided on the floor slab and on both sides of the column, with each pre-embedded support corresponding to a connecting lug. A telescopic strut connects the connecting lug and the pre-embedded support on the same side. In this way, the telescopic struts on both sides of the column further increase the lateral support of the column, providing support on the inner side and both sides of the column, i.e., the column has three-way support, making the structure more stable and providing stronger wind resistance.

[0011] Furthermore, the telescopic strut includes a lower tube, an upper tube, an upper adjusting screw, and a lower adjusting screw. The lower end of the upper tube is fitted onto the lower tube and can slide along the length of the lower tube. An adjusting nut is welded and fixed to the upper end of the upper tube and the lower end of the lower tube. The lower end of the upper adjusting screw is threadedly engaged with the adjusting nut on the upper tube, and the upper end of the lower adjusting screw is threadedly engaged with the adjusting nut on the lower tube. An upper connecting piece that mates with a connecting lug is fixed to the upper end of the upper adjusting screw, and a lower connecting piece that connects to a pre-embedded support is fixed to the lower end of the lower adjusting screw. In this way, the telescopic strut can extend and retract along its length. During installation, its length can be adjusted in real time according to the position of the pre-embedded support and the installation height of the connecting plate to adapt to installation requirements. Simultaneously, the upper tube, lower tube, upper adjusting screw, and lower adjusting screw are all rigid components, providing excellent support.

[0012] Furthermore, multiple positioning holes are spaced apart along the length of the lower tube. After the upper tube is adjusted to its extended or retracted position, a tightening bolt passes through the positioning holes to fix the upper and lower tubes together. In this way, after adjusting the upper tube, the lower tube can be fixed to the upper tube by the tightening bolt, increasing its strength.

[0013] Furthermore, reinforcing square steel bars are also connected to the columns and diagonal braces at an angle. This addition of reinforcing square steel bars further increases the connection strength between the diagonal braces and the columns. Attached Figure Description

[0020] Currently, when installing attached lifting scaffolding, wall-mounted supports are typically installed directly on the exterior wall, followed by the installation of climbing rails and the main body of the scaffolding on one side of the wall-mounted supports. However, if the floor has a high ceiling, installing only one wall-mounted support on each floor's exterior wall is insufficient for the installation of the climbing rails. Therefore, at least one additional wall-mounted support needs to be added in the middle of the floor to meet the installation requirements of the main body of the scaffolding. Therefore, it is crucial to develop a support frame that provides sufficient support for the wall-mounted supports in the middle of the floor and ensures that the wall-mounted supports on the exterior wall are on the same installation plane.

[0021] like Figures 1-4As shown, this embodiment provides a support structure for an elevated floor-mounted attached lifting scaffold, including a column 4 fixed to the floor slab and at least one wall-mounted support 2 installed on the outside of the column 4; a mounting seat 3 is also provided between the wall-mounted support 2 and the column 4, the mounting seat 3 being a square frame welded from multiple square steel bars (specifically, the mounting seat 3 includes two spaced square frames and a connecting rectangular tube welded and fixed between the two square frames), and the thickness of the mounting seat 3 corresponds to the thickness of the edge beam 1 on the floor slab. The wall-mounted support 2, the mounting seat 3, and the column 4 are fixedly connected by at least two double-ended screws 10 and fastening nuts placed at both ends of the double-ended screws 10; a grounding beam 5 is provided at the lower end of the column 4 and fixedly connected thereto, the grounding beam 5 being placed on the floor slab and fixed to the floor slab by grounding bolts and locking nuts; two diagonal braces 8 are spaced apart on the inner side of the column 4, and the upper and lower ends of the two diagonal braces 8 are respectively connected to the column 4 and the grounding beam 5. In this way, by adding a mounting base 3 between the column 4 and the wall-mounted support 2, and connecting and fixing the column 4, mounting base 3, and wall-mounted support 2 with double-ended screws 10 and fastening nuts, the inner end of the wall-mounted support 2 is aligned with the outer side of the edge beam 1, and with the same mounting surface as other wall-mounted supports 2 fixed to the exterior wall, effectively ensuring the installation of the climbing guide rail. Simultaneously, the lower end of the column 4 is connected to a grounding beam 5, which is fixed to the floor slab with grounding bolts, making installation and disassembly convenient and ensuring high structural stability.

[0022] like Figure 3As shown, the column 4 includes two vertically arranged left square tubes 41 and two right square tubes 42. Multiple horizontally arranged connecting square tubes 43 are spaced between the left and right square tubes 41 and 42. The left square tubes 41, connecting square tubes 43, and right square tubes 42 are connected by a pull rod that passes through each tube sequentially and is then fixed with a threaded fastening nut. The grounding beam 5 is the same width as the column 4 and is assembled from multiple rectangular tubes of equal length. Multiple connecting through holes are evenly spaced along the length of each left square tube 41, right square tube 42, and rectangular tube. A connecting plate 6 is provided on both the left and right sides of the column 4, tightly abutting the sides of the column 4 and the grounding beam 5. The connecting plate 6 is fixed to the column 4 and the grounding beam 5 by fasteners. Each connecting plate 6 has multiple mounting holes corresponding to the connecting through holes on the left square tube 41, right square tube 42, and rectangular tube. The tie rods pass through the connecting plate 6 and the column 4, as well as the connecting plate 6 and the grounding beam 5, and are secured to the connecting plate 6, column 4, and grounding beam 5 by engaging with nuts. Thus, the column 4, composed of multiple square tubes connected and fixed by tie rods, ensures that the column 4 meets the set strength requirements. Furthermore, the square tubes and connecting components are all standard building materials, eliminating the need for customization of the column 4. The grounding beam 5 is composed of multiple rectangular tubes connected together. The grounding beam 5 is fixed to the column 4 via the connecting plate 6, and the rectangular tubes of the grounding beam 5 are fixed to the square tubes of the column 4 via fasteners, making installation and disassembly convenient.

[0023] Furthermore, a diagonal brace mounting plate 7 is provided on the opposite side of the mounting base 3, which is tightly attached to the inner side of the column 4. Two spaced-apart first lugs 71 are vertically fixed on the diagonal brace mounting plate 7, and two second lugs are provided on two of the rectangular tubes of the grounding beam 5. The upper and lower ends of the diagonal brace 8 are fixedly connected to the first lugs 71 and the second lugs respectively through connectors. In this way, the first lugs 71 provided on the diagonal brace mounting plate 7 correspond to the second lugs on the grounding beam 5, which facilitates the connection and fixation of the diagonal brace 8.

[0024] Furthermore, a connecting lug 72 is welded and fixed on both sides of the diagonal brace mounting plate 7. An embedded support 11 is provided on both the floor slab and both sides of the column 4, with each embedded support 11 corresponding to a connecting lug 72. A telescopic strut 9 is connected between the connecting lug 72 and the embedded support 11 on the same side. Two screw holes for double-ended screws 10 are also provided in the middle of the diagonal brace mounting plate 7; one is a circular hole, and the other is a strip-shaped hole. Thus, the telescopic struts 9 provided on both sides of the column 4 further increase the lateral support of the column 4, providing support on the inner side and both sides of the column 4, i.e., the column 4 has three-way support, making the structure more stable and providing stronger wind resistance.

[0025] Furthermore, the telescopic support rod 9 includes a lower tube 93, an upper tube 94, an upper adjusting screw 92, and a lower adjusting screw 91. The lower end of the upper tube 94 is fitted onto the lower tube 93 and can slide along the length of the lower tube 93. An adjusting nut is welded and fixed to the upper end of the upper tube 94 and the lower end of the lower tube 93. The lower end of the upper adjusting screw 92 is threadedly engaged with the adjusting nut on the upper tube 94, and the upper end of the lower adjusting screw 91 is threadedly engaged with the adjusting nut on the lower tube 93. An upper connecting piece that mates with the connecting lug 72 is fixed to the upper end of the upper adjusting screw 92, and a lower connecting piece that connects to the pre-embedded support 11 is fixed to the lower end of the lower adjusting screw 91. In this way, the telescopic support rod 9 can extend and retract in the length direction. During installation, its length can be adjusted in real time according to the position of the pre-embedded support 11 and the installation height of the connecting plate 6 to adapt to installation requirements. Meanwhile, the upper tube 94, the lower tube 93, the upper adjusting screw 92, and the lower adjusting screw 91 are all rigid components, which can provide excellent support.

[0026] Furthermore, multiple positioning holes are provided at intervals along the length of the lower tube 93. After the upper tube 94 is adjusted to the desired position, a tightening bolt is passed through the positioning holes to fix the upper tube 94 and the lower tube 93 together. In this way, after adjusting the upper tube 94, the lower tube 93 can be fixed to the upper tube 94 by the tightening bolt, increasing its strength.

[0027] Furthermore, reinforcing square steel bars arranged at an angle are connected to the column 4 and the diagonal brace 8. In this way, the connection strength between the diagonal brace 8 and the column 4 can be further increased after adding the reinforcing square steel bars.

[0028] In this embodiment, the square tubes on the column 4, the rectangular tubes on the grounding beam 5, the diagonal brace 8, the upper tube 94 and the lower tube 93 of the telescopic support rod 9, and the reinforcing square steel are all steel rectangular tubes, and multiple holes are provided at equal intervals along the length of each rectangular tube to facilitate the connection and installation of each component.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
