Abstract
Description
Technical Field
[0001] This utility model relates to a construction device, specifically a suspended operating platform. Background Technology
[0002] In the field of building construction, steel beams, as the core load-bearing components of large-span spatial structures, are widely used in industrial plants, commercial complexes, and transportation hubs. Their installation locations are often at height, and the surfaces below are often unsupported, sometimes requiring decorative or other construction work on the lower sides of the steel frame structure composed of steel beams.
[0003] When working under steel beams, scaffolding can be erected to build a three-dimensional support frame from the ground up to the working surface under the steel beams, forming a stable working platform. However, this method is not suitable for working at heights. While movable and liftable mechanized platforms are suitable for working at heights and can directly transport personnel and tools to the working surface under the steel beams, they require a flat and unobstructed ground surface, and the cost of purchasing or renting such equipment is relatively high.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.
[0021] like Figure 1 As shown, the suspended operating platform of this utility model is located below a steel frame structure. The steel frame structure includes several transverse steel beams and longitudinal steel beams 10. The suspended operating platform includes a main keel 1, U-shaped suspension rods 2, a fixing structure 3, secondary keels 4, and scaffold boards 5. The main keel 1 is located below the longitudinal steel beams 10 and extends along the extension direction of the longitudinal steel beams 10. Several U-shaped suspension rods 2 are suspended from each longitudinal steel beam 10 through the fixing structure 3, and the lower end of the U-shaped suspension rods 2 supports the main keel 1 below the main keel. The secondary keel 4 is erected above the main keel 1, and the extension direction of the secondary keel 4 is perpendicular to the extension direction of the longitudinal steel beams 10. The secondary keel 4 and the main keel 1 form a keel frame. The scaffold boards 5 are laid on top of the secondary keel 4.
[0022] Multiple lifting points are set on each longitudinal steel beam 10 as needed, and U-shaped lifting rods 2 are set at each lifting point. The numerous U-shaped lifting rods 2 serve as load-bearing components to ensure the safety of the entire suspended platform.
[0023] like Figure 2 As shown, another configuration of the keel frame in this invention involves a secondary keel 11 perpendicular to the secondary keel 4, positioned above the secondary keel 4. The main keel 1, secondary keel 4, and secondary keel 11 form the keel frame. Scaffold boards 5 are laid on top of the secondary keel 11 to increase the stability of the suspended operating platform. Fixing clamps 6 are used to connect and fix the secondary keel 4 and secondary keel 11 at their connection points; the scaffold boards 5 and secondary keel 11 are then connected by bolts.
[0024] like Figure 3As shown, the fixing structure 3 includes an angle steel 301, a rubber pad 302, and a nut 303. The rubber pad 302 is positioned above the longitudinal steel beam 10, and the angle steel 301 is positioned above the rubber pad 302 to prevent the angle steel 301 from sliding on the longitudinal steel beam 10. The angle steel 301 spans across the longitudinal steel beam 10, and its length is greater than the width of the longitudinal steel beam 10. One leg of the angle steel 301 is in contact with the upper surface of the top of the longitudinal steel beam 10. The length direction of the angle steel 301 is perpendicular to the extension direction of the longitudinal steel beam 10, and both ends of the angle steel 301 protrude outward in the width direction of the longitudinal steel beam 10. Connecting holes are provided at both ends of the angle steel 301. The two ends of the upper part of the U-shaped suspension rod 2 are threaded, and each of the two ends of the upper part of the U-shaped suspension rod 2 passes through a connecting hole and is threadedly connected to the nut 303.
[0025] This utility model can use two nuts 303 to fix the U-shaped suspension rod 2. A washer is provided between the nut 303 and the angle steel 301 to increase the stability of the connection between the U-shaped suspension rod 2 and the angle steel 31.
[0026] like Figure 4 As shown, at the connection between the secondary keel 4 and the main keel 1, the secondary keel 4 and the main keel 1 are connected by a fixing sleeve 6. The scaffold board 5 is connected to the secondary keel 4 using M5 self-tapping bolts, and the bolt spacing is less than or equal to 600mm.
[0027] like Figure 5 As shown, this utility model also provides several uprights 7 on the edge of the keel frame, and several horizontal bars 12 on the uprights 7, with a spacing of 600mm between the upper and lower horizontal bars 12; diagonal braces 8 are provided on the inner side of the uprights 7 every 2.4m, the upper end of the diagonal brace 8 can be welded to the uprights 7, and the lower end of the diagonal brace 8 can be bolted to the scaffold board 5; and toe boards 9 are provided at the bottom edge of the keel frame.
[0028] The bottom of the upright 7 is fixed to the keel and the horizontal bar 12 by welding. The bottom of the upright 3 is welded to the keel with a 250mm long M25 steel bar. The height of the toe plate 9 in this utility model is 20cm.
[0029] The guardrail consists of upright pole 7, horizontal pole 12, diagonal brace 8, and toe board 9, which further ensures the safety of construction workers.
[0030] This utility model also provides support rods with a length of 1.2m at both ends of the longitudinal steel beam 10, with the distance between the support rods not exceeding 8m. Two steel wire ropes are respectively installed at 1200mm and 600mm from the beam surface of the support rods. The steel wire ropes are connected to the support rods at both ends of the longitudinal steel beam, and the steel wire ropes are tensioned and used as safety ropes.
[0031] The wire rope has a diameter of 8mm. After the wire rope is tensioned, both ends are fixed with rope clamps with a diameter of 8mm. The number of rope clamps shall not be less than 3, and the spacing between the rope clamps shall be kept at 6cm. The length of the last rope clamp from the end of the rope shall not be less than 140mm.
[0032] When construction workers walk on the platform, their safety belts must be suspended from the steel wire rope.
[0033] During installation, the following steps are taken: First, support rods and wire ropes are installed at both ends of the longitudinal steel beam. Second, installers place rubber pads 302 and angle steel 301 on the steel beam and suspend the U-shaped suspension rods 2 from the longitudinal steel beam 10. Then, a tower crane or truck crane is used in conjunction with a guide rope to control the direction of the main keel 1, and the main keel 1 and secondary keel 4 are erected on the U-shaped suspension rods 2. Next, the first scaffold board 5 is laid on the secondary keel 4, and construction workers stand on the ladder suspended from the steel beam. The construction platform connects the main keel 1 and the secondary keel 4 with fixing sleeves 6. When there is a secondary keel 11, the secondary keel 11 and the secondary keel 4 are connected with fixing sleeves 6. The scaffold board 5 is fixed to the secondary keel 4 with bolts. Then, the next scaffold board 5, the intersection nodes 4 of other main keels 1 and secondary keels, and the intersection nodes of other secondary keels and secondary keels are fixed. Finally, the uprights 7, horizontal bars 12, diagonal braces 8 and toe boards 9 are installed on the suspended operating platform.
[0034] After installation, construction workers must suspend their safety belts from the safety ropes when walking on the platform.
