Description

Technical Field

[0001] This utility model belongs to the field of scaffolding, and specifically relates to a horizontal load-bearing truss for lifting scaffolding. Background Technology

[0002] Climbing scaffolding is a commonly used construction equipment in high-rise building construction. It consists of guide rails and electric hoists installed on the scaffold, wall-mounted supports and lifting supports installed on the exterior walls of the building. The wall-mounted supports limit and guide the guide rails, and the lifting supports are connected to the lifting chains of the electric hoists to drive the scaffold to rise and fall along the exterior walls of the building, thus facilitating construction workers to carry out their work.

[0003] However, the structural components of existing climbing scaffolds are not designed according to the same standards by different manufacturers, and their shapes and dimensions are different. This makes it impossible to achieve universality of climbing scaffold parts from different manufacturers. When climbing scaffolds are used in different engineering projects, due to differences in building structures, when climbing scaffold materials need to be supplemented, the climbing scaffold subcontractor has to repurchase from the original manufacturer instead of borrowing from or integrating social resources from peers. This results in low flexibility and high operating costs.

[0004] Patent document with application number "202410346224.1" discloses an attached lifting scaffold for construction protection in prefabricated buildings. It includes an inner upright, with a triangular brace bolted to the rear end of each inner upright. A horizontal support truss is bolted to the rear end of the triangular brace. Steel plate scaffolding and steel mesh scaffolding are fixedly connected to the rear end of the inner upright. An outer upright is fixedly connected to the rear end of the steel plate scaffolding and steel mesh scaffolding. An outer protective net is fixedly connected to the rear end of the outer upright. A guide rail is fixedly connected to the front end of the inner upright, and a support mechanism is provided on the circumference of the guide rail. A lifting mechanism is bolted to the surface of the inner upright. In this prior art, the inner upright, outer upright, and triangular brace of the lifting scaffold all use special standards. Their cross-sectional dimensions, length modulus, and hole positions are all non-standard, making them incompatible with commercially available scaffolding parts. This results in low flexibility and high cost.

In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application.

[0043] There are two main frames 100 arranged parallel to each other. Multiple sub-frames 200 are arranged between the two main frames 100. Planar connecting trusses 300 are detachably connected to each sub-frame 200 or between a sub-frame 200 and a main frame 100, and remain perpendicular to both the main frames 100 and the sub-frames 200. Each main frame 100 includes: a first main vertical member 110, a first secondary vertical member 120, a first horizontal member 130, and a first diagonal member 140. The first main vertical member 110 and the first secondary vertical member 120... Two first horizontal bars 130 are arranged in parallel, connecting the first main vertical bar 110 and the first secondary vertical bar 120 and perpendicular to them. The first main vertical bar 110, the first secondary vertical bar 120, and the two first horizontal bars 130 together form a first passage 150. Two first diagonal bars 140 are arranged within the first passage 150. The two ends of the first diagonal bars 140 are fixedly connected to the first main vertical bar and the first secondary vertical bar 120 respectively, and the two first diagonal bars 140 extend towards the upper end of the first passage 150. The guide rail connector 400 is C-shaped, with a bayonet 420 at one end. The bayonet 420 engages with the side of the first main vertical rod 110 and is welded to it. First connecting holes 410 are provided on both sides of the guide rail connector 400, allowing the bayonet 420 to pass through. The bayonet 420 can be engaged with the connecting rod of the climbing frame guide rail 700, and bolts are passed through the first connecting holes 410 to connect the guide rail and the guide rail connector 400. Here, the climbing scaffold guide rail 700 is preferably selected in the form of a square connecting tube. The structural form of the climbing scaffold guide rail 700 is common knowledge in the industry and will not be described in detail here. The upper and lower ends of the first main vertical rod 110 and the first secondary vertical rod 120 are respectively welded with a first ear plate 160. The first ear plate 160 is perpendicular to the plane where the first passage 150 is located. The two sides of the first ear plate 160 extend outward and are respectively opened with two first through nail holes 161. The two first through nail holes 161 are set in the vertical direction.

[0044] In addition, within the same first passage 150, the connection ends of the two first diagonal bars 140 and the first main vertical bar 110 are close to each other, while the connection ends of the two first diagonal bars 140 and the first secondary vertical bar 120 are far apart from each other, thereby enabling the first diagonal bars 140 and the first horizontal bar 130 to form a triangular support structure, thereby improving the support strength of the horizontal support bar 310.

[0045] The sub-frame 200 includes: a second vertical rod 210, a second horizontal rod 220, and a second diagonal rod 250. There are two second vertical rods 210 arranged in parallel. Two second horizontal rods 220 are connected between the two second vertical rods 210, with each end welded perpendicularly to the side of one of the second vertical rods 210. A second passageway 230 is formed between the two second vertical rods 210 and the two second horizontal rods 220. A second ear plate 240 is welded to the upper and lower ends of each second vertical rod 210. The second ear plate 240 and the second passageway 230 are located at... The plane is vertical. The two sides of the second ear plate 240 extend outward and are respectively provided with two second through holes 241. The position of the second through holes 241 is consistent with the position of the first through holes 161 and the diameter is the same. Two second diagonal rods 250 are provided in the second through opening 230. The two ends of the second diagonal rods 250 are respectively welded to the side of a second vertical rod 210 and the two second diagonal rods 250 are close to the upper end and the lower end of the second through opening 230 respectively. The inclination direction of the two second diagonal rods 250 is consistent with the inclination direction of the first diagonal rod 140.

[0046] In addition, the sub-frame 200 also includes another implementation: when the load is small or when the frame needs to be installed in the vertical direction of the horizontal load-bearing truss, the two ends of the second horizontal bar 220 are detachably fixed to the second vertical bar 210; a third ear plate 260 is welded to the upper and lower ends of the second vertical bar 210, the third ear plate 260 is perpendicular to the second ear plate 240 and the two sides of the third ear plate 260 extend outward and are provided with two third through nail holes 261; a fourth ear plate 221 is welded to the two ends of the second horizontal bar 220, the fourth ear plate 221 is provided with a fourth through nail hole 222, the position of the fourth through nail hole 222 corresponds to the position of the third through nail hole 261 and is connected by bolts.

[0047] A horizontal strut 310 is provided at the upper and lower ends of the planar connecting truss 300. A diagonal strut 320 connects the two horizontal struts 310. A fifth ear plate 311 is welded to each end of the horizontal strut 310. A fifth through-bolt hole 312 is provided on the fifth ear plate 311. The position of the fifth through-bolt hole 312 corresponds to the position of the second through-bolt hole 241 and the first through-bolt hole 161, and they are connected by bolts. The upper end of the planar connecting truss 300 is also provided with... A reinforcing cross brace 330 is parallel to the cross brace 310 and is fixedly connected by a connecting plate 340. When the span of both sides of the planar connecting truss 300 is greater than twice the module of the scaffold cross brace, there are more than two diagonal braces 320. The connecting ends of each diagonal brace 320 facing the upper end of the planar connecting truss 300 are far apart from each other, and the connecting ends of each diagonal brace 320 facing the lower end of the planar connecting truss 300 are close to each other, thus forming an inverted triangular structure.

[0048] Scaffolding connection parts 500 are welded to the upper ends of the first main vertical bar 110, the first secondary vertical bar 120, and the second vertical bar 210. The spacing between each scaffolding connection part 500 is a multiple of the module of the scaffolding horizontal bar. The industry standard specifies that the module of the scaffolding horizontal bar is 30cm. The scaffolding connection part 500 is a connection structure such as a flange connection plate, a sleeve, or a single or double ear plate. Here, the scaffolding connection part 500 on the first main vertical bar 110 and the first secondary vertical bar 120 is preferably a flange connection plate, and the scaffolding connection part 500 on the second vertical bar 210 is preferably a sleeve.

[0049] A detachable reinforcing and fixing rod 600 is also installed on the planar connecting truss 300. The reinforcing and fixing rod 600 has a second connecting hole 610 corresponding to the first connecting hole 410. The first connecting hole 410 and the second connecting hole 610 are used to install the lifting point fixing seat 800. The lifting point fixing seat 800 is a part used to connect the upper and lower lifting points of the climbing frame electric hoist. Its structure and usage are common knowledge in the industry and will not be described in detail here. Two hooks 620 are welded to the side of the reinforcing and fixing rod 600. The hooks 620 can be hooked onto the body of the cross brace 310 from below. Bolts can also be installed on the body of the reinforcing and fixing rod 600. The end of the bolt can extend from the opening of the hook 620 and lock the cross brace 310 to prevent the hook 620 from coming off.

[0050] In summary, the horizontal load-bearing truss for the lifting scaffolding in this embodiment is modularly assembled through a detachable main frame 100, a secondary frame 200, and a planar connecting truss 300. Scaffolding connection parts 500 are provided at the top of the main frame 100 and the secondary frame 200 according to the scaffolding crossbar module. This allows for increased installation density according to the module to ensure overall structural strength, thus ensuring compatibility with ordinary scaffolding system members and providing high flexibility in use. Guide rail connectors 400 are provided on the main frame 100, and reinforcing and fixing hangers 600 are installed on the planar connecting truss 300, thereby stably connecting the guide rails and the hanging point fixing seats 800, enabling it to have high load-bearing capacity when used compatible with ordinary scaffolding members.
