Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a prefabricated basket-style tie rod cantilever scaffolding. Background Technology

[0002] Cantilevered scaffolding utilizes outward-extending cantilever structures from the building structure's edges to support the external scaffolding, transferring all or part of the scaffolding's load to the building structure. The cantilevered support structure of the cantilevered scaffolding must possess sufficient strength, stability, and rigidity to effectively transfer the scaffolding's load to the building structure.

[0003] As shown in the reference case "Panel Tie Rod Cantilever Scaffolding for Prefabricated Building Construction" (Announcement No. CN219826055U), the supporting structure is pre-embedded inside the main building structure. This solves the technical problem of conventional cantilever scaffolding requiring post-construction openings for fixation to the main building, which increases the technical steps for subsequent repairs and waterproofing. This utility model can greatly improve the erection speed of the cantilever layer. Compared with the traditional flat cantilever, this method does not affect subsequent construction such as secondary structure masonry and ground construction. The standardized production of main beams and other components ensures high safety performance. It reduces the length of I-beams, and the main beams and I-beams can be reused, significantly reducing costs.

[0004] According to the above reference materials, the upper and lower tie rods in the above device are made of high-strength bolts. The main beam is equipped with a movable upright base to facilitate the installation of the scaffold uprights. The basket tie rod can adjust its length. After the high-strength bolts pass through the fixing plate, they are fixed to the fixing plate by full welding with double nuts and washers. However, this device has poor bending resistance for cantilevered scaffolds, uneven stress distribution, and is not convenient for the stable installation of cantilevered scaffolds, thus reducing the installation effect of cantilevered scaffolds. Utility Model Content

[0005] Therefore, it is necessary to provide a prefabricated basket-style tie rod type cantilever scaffolding to address the problem of inconvenience in stabilizing the installation of cantilever scaffolding.

[0006] The structure includes a main body, on one side of the bottom of the main body, two load-bearing steel beams are installed, and two ear plates are fixedly connected to the top of the load-bearing steel beams. An installation mechanism is installed at the top of the load-bearing steel beams. The installation mechanism includes two sets of steel tie rods installed on both sides of the main body. Each set of steel tie rods consists of two steel tie rods, and turnbuckles are threaded between the two steel tie rods. A connecting plate is fixedly connected to one end of each steel tie rod. One connecting plate is hinged to the ear plate, and the other connecting plate is installed on one side of the top of the main body by high-strength bolts. Reinforcing components are provided on the inner wall of the turnbuckles.

[0007] In one embodiment, the mounting mechanism further includes mounting plates slidably connected to both ends of the inner wall of the turnbuckle, and the inner wall of the mounting plates is rotatably connected to a threaded sleeve, which is threadedly connected to the steel tie rod.

[0008] In one embodiment, a number of evenly arranged grooves are provided at one end of the outer wall of the threaded sleeve.

[0009] In one embodiment, a limit rod is provided on one side of the outer wall of the mounting plate.

[0010] In one embodiment, a plurality of evenly arranged slots are provided on one side of the turnbuckle, and one end of the limiting rod passes through the mounting plate and is embedded in the inner wall of the slot.

[0011] In one embodiment, the reinforcement component includes two reinforcement rods fixedly connected to one end of the bottom of the load-bearing steel beam. Several evenly arranged fixing bolts are installed at one end of the load-bearing steel beam, and one end of each fixing bolt passes through the load-bearing steel beam and the main structure and is threadedly connected to a nut.

[0012] In one embodiment, two longitudinal steel beams are mounted on the top of the two load-bearing steel beams, and the longitudinal steel beams are disposed on one side of the ear plate.

[0013] Beneficial effects

[0014] 1. The above-mentioned prefabricated turnbuckle-type cantilever scaffolding has two steel tie rods connected to one side of the top of the main structure and the ear plate respectively through connecting plates at one end. The turnbuckle between the two steel tie rods can be tightened to connect them. The two steel tie rods and the turnbuckle are inclined to one side and cooperate with the main structure and the load-bearing steel beam to form a triangular steel load-bearing system. The two sets of steel tie rods can further improve the stability of the cantilever scaffolding. The two threaded sleeves inside the turnbuckle are connected to the steel tie rods. The mounting plate moves with the threaded sleeves inside the turnbuckle. The limiting rod cooperates with multiple slots to fix the threaded sleeves and the mounting plate, which can strengthen the steel tie rods, improve the bending resistance of the cantilever scaffolding, and increase the strength of the cantilever scaffolding.

[0015] 2. When the load-bearing steel beam is installed on one side of the bottom of the main structure, the load-bearing steel beam and two reinforcing rods inclined to one end form a triangular load-bearing system, which can reinforce the load-bearing steel beam. Multiple fixing bolts are installed in a triangular pattern to reinforce the load-bearing steel beam. Two longitudinal steel beams are installed on the load-bearing steel beam with bolts, which can be used to install scaffolding, improve the support strength of cantilever scaffolding, and improve the use effect of cantilever scaffolding.

[0028] The following is combined with Figures 1-4 This invention describes a prefabricated flower basket tie rod type cantilever scaffold.

[0029] In one embodiment, a prefabricated basket-stayed cantilever scaffold includes a main structure 100. Two load-bearing steel beams 200 are installed on one side of the bottom of the main structure 100. Two ear plates 300 are fixedly connected to the top of the load-bearing steel beams 200. An installation mechanism 400 is installed on the top of the load-bearing steel beams 200. The installation mechanism 400 includes two sets of steel tie rods 410 installed on both sides of the main structure 100. Each set of steel tie rods 410 consists of two steel tie rods. A turnbuckle 420 is threaded between the two steel tie rods 410. A connecting plate 430 is fixedly connected to one end of the steel tie rod 410. One connecting plate 430 is hinged to the ear plate 300, and the other connecting plate 430 is installed on one side of the top of the main structure 100 by high-strength bolts. A reinforcing component 490 is provided on the inner wall of the turnbuckle 420.

[0030] It should be noted that the cantilever scaffolding consists of a cantilever beam, a base, a support assembly, an anchoring device, and the scaffolding body. One end of the cantilever beam is fixed to the floor slab or beam of the building with high-strength bolts. The steel tie rod 410 is fixed to the floor slab or beam of the building. The steel tie rod 410 is connected to the ear plate 300 on the cantilever beam to fix the cantilever beam. The other end of the cantilever beam cantilevered the external support scaffolding. The load-bearing steel beam 200 is fixed to the main structure 100 with high-strength bolts. The diagonal steel tie rod 410 is fixed to the upper main structure 100. The steel tie rods 410 are connected to each other through the ear plate 300 and are tightened by turnbuckles 420 to form a triangular steel load-bearing system. This can optimize the bending resistance of the cantilever scaffolding without affecting its normal use.

[0031] like Figure 2 and Figure 3 As shown, the mounting mechanism 400 also includes a mounting plate 440 slidably connected to both ends of the inner wall of the turnbuckle 420. A threaded sleeve 450 is rotatably connected to the inner wall of the mounting plate 440. The threaded sleeve 450 is threadedly connected to the steel tie rod 410. One end of the outer wall of the threaded sleeve 450 is provided with several evenly arranged grooves 460. A limit rod 470 is provided on one side of the outer wall of the mounting plate 440. A number of evenly arranged slots 480 are provided on one side of the turnbuckle 420. One end of the limit rod 470 passes through the mounting plate 440 and is embedded in the inner wall of the slot 480.

[0032] In this embodiment, one end of each of the two steel tie rods 410 is connected to the main structure 100 and the ear plate 300 respectively via a connecting plate 430. The turnbuckle 420 is threadedly connected to the two steel tie rods 410. As the turnbuckle 420 rotates, the two steel tie rods 410 can be tightened. The two threaded sleeves 450 on the turnbuckle 420 can be threadedly connected to the steel tie rods 410 to reinforce them. The steel tie rods 410 are also reinforced by inserting the limiting rod 470 on one side of the mounting plate 440 into the slot 480. This can improve the bending resistance and stability of the cantilever scaffold.

[0033] like Figure 4 As shown, the reinforcement component 490 includes two reinforcement rods 491 fixedly connected to one end of the bottom of the load-bearing steel beam 200. Several evenly arranged fixing bolts 492 are installed at one end of the load-bearing steel beam 200. One end of the fixing bolts 492 passes through the load-bearing steel beam 200 and the main structure 100 and is threaded with a nut. Two longitudinal steel beams 493 are installed at the top of the two load-bearing steel beams 200. The longitudinal steel beams 493 are located on one side of the ear plate 300.

[0034] In this embodiment, two load-bearing steel beams 200 are fixed by fixing bolts 492 and washers. Two reinforcing rods 491 are installed obliquely at the bottom of the load-bearing steel beams 200 to reinforce them. Two longitudinal steel beams 493 are installed on the load-bearing steel beams 200 by high-strength bolts. The longitudinal steel beams 493 are installed on the load-bearing steel beams 200 by two sleeves and bolts. This can improve the stability of the cantilevered scaffolding and increase the installation efficiency of the cantilevered scaffolding.

[0035] Working principle: The load-bearing steel beam 200 is installed on one side of the bottom of the main structure 100 by fixing bolts 492. One end of the steel tie rod 410 is connected to the ear plate 300 by a high-strength bolt. A turnbuckle 420 is threaded between the two steel tie rods 410. The other end of the steel tie rod 410 is connected to the main structure 100 by a high-strength bolt. When the turnbuckle 420 is tightened, it tightens the two steel tie rods 410. The mounting plate 440 moves along the turnbuckle 420. The inner wall of 0 moves to one end, and the rotating threaded sleeve 450 is threadedly connected to the steel tie rod 410 to reinforce the steel tie rod 410. The limiting rod 470 passes through the mounting plate 440 and is embedded in the slot 480 to fix the mounting plate 440. When the load-bearing steel beam 200 is installed, the two reinforcing rods 491 can reinforce the load-bearing steel beam 200. The two longitudinal steel beams 493 are installed on the load-bearing steel beam 200 by bolts. The upright is directly sleeved on the sleeve at the top of the longitudinal steel beam 493. The scaffolding is installed on the longitudinal steel beam 493 by bolts.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
