Description

Technical Field

[0001] The invention relates to the field of building tools, in particular to a safety scaffold for the construction of a spherical building steel structure. Background Art

[0002] Scaffolding is an important tool to assist workers in the construction of building walls. It can be flexibly assembled according to the height of the building walls. However, the current scaffolding usually forms a square structure after splicing. When facing a curved building wall, although it can be built, it is difficult to fit tightly with the curved wall, resulting in a large gap between the scaffolding and the wall. This situation not only increases the difficulty of construction for workers, but also increases the risk of workers falling due to excessive spacing. Although current technology can adapt to curved walls by customizing curved scaffolding with a specific curvature, due to its fixed curvature, when facing walls with different curvatures, this curved scaffolding has poor adaptability and may still not fit perfectly.

[0003] In addition, when the scaffolding is built to a higher position, in order to ensure the safety of workers, the conventional practice is to lay a protective net on the side of the scaffolding away from the wall to prevent workers from falling. However, when the entire scaffolding needs to be covered, due to the large overall area, this not only increases the difficulty of laying the scaffolding for workers, but also makes the subsequent storage and disassembly work more arduous. Summary of the invention

[0004] In order to overcome the shortcomings of existing scaffolding that it is difficult to fit tightly against curved walls due to fixed structure and curvature limitation, resulting in increased construction difficulty and safety hazards, and at the same time, the laying and subsequent treatment of large-area protective nets during high-altitude operations also increase the complexity of the work and labor intensity, the present invention provides a spherical building steel structure construction safety scaffolding.

[0029] Example 1

[0030] like Figure 1-Figure 5As shown, a spherical building steel structure construction safety scaffolding includes a steel pipe 1, a vertical beam plate 2, a horizontal beam plate 3, a bearing plate 4, a wall connecting member 5, a diagonal brace 7 and a tossing brace 8; each steel pipe 1 is connected to two clamping parts 1001, and each clamping part 1001 is provided with a plurality of clamping grooves; a vertical beam plate 2 is commonly connected between every two front and rear opposite steel pipes 1; a first embedded part 2001 is provided at both ends of each vertical beam plate 2, and each first embedded part 2001 is clamped on the clamping groove of the adjacent clamping part 1001; a horizontal beam plate 3 is commonly connected between every two left and right opposite steel pipes 1 located at the rear side; each horizontal beam Both ends of the plate 3 are provided with a second engaging portion 3001, and each second engaging portion 3001 is clamped on the clamping groove on the adjacent clamping portion 1001; a bearing plate 4 is placed on each of the two vertical beam plates 2 that are opposite to each other; a pedal 4001 is provided on the upper side of each bearing plate 4; two first sliding grooves 2002 are provided on the upper side of each vertical beam plate 2; a slider is provided on the lower side of each bearing plate 4, and the slider slides on the adjacent first sliding grooves 2002; a wall connecting piece 5 is clamped on all the steel pipes 1 on the front side; a diagonal brace 7 is clamped on all the steel pipes 1 on the rear side; a throw brace 8 is clamped on all the steel pipes 1 on the rear side;

[0031] It also includes a slide plate 6 and a storage system; each carrier plate 4 is provided with a plurality of second slide grooves 4002; each second slide groove 4002 is slidably connected to a slide plate 6; and each carrier plate 4 is connected to a storage system.

[0032] It also includes a support plate 101 ; a plurality of support plates 101 are slidably connected in each bearing plate 4 ; and each support plate 101 is fixedly connected to the adjacent slide plate 6 .

[0033] It also includes bolts 102 and locking plates 103; a plurality of bolts 102 are rotatably connected to the lower side of each bearing plate 4; a locking plate 103 is commonly connected between every two left and right opposite bolts 102; a rectangular hole is opened on each second slide groove 4002; a plurality of extrusion parts 10301 are arranged on each locking plate 103, and each extrusion part 10301 is vertically opposite to the rectangular hole on the adjacent second slide groove 4002.

[0034] Each pedal 4001 is provided with a plurality of through slots.

[0035] The surface of each pedal 4001 is made of anti-slip material to prevent workers from slipping and getting injured when walking on the load-bearing plate 4.

[0036] After the locking plate 103 locks the slide plate 6, a gap is left between the locking plate 103 and the lower side of the carrying plate 4, so that workers can put their fingers in to hold the carrying plate 4, making transportation more convenient.

[0037] Before construction, workers first fix four steel pipes 1 on the ground, then insert the first engaging portion 2001 on the vertical beam plate 2 into the engaging groove of the corresponding engaging portion 1001, so that the vertical beam plate 2 is fixed between the two steel pipes 1 opposite to each other in the front and rear, then insert the second engaging portion 3001 on the cross beam plate 3 into the engaging groove of the corresponding engaging portion 1001, so that the cross beam plate 3 is also fixed on the engaging portion 1001, and finally, insert the slider on the lower side of the load-bearing plate 4 into the first sliding groove 2002 of the vertical beam plate 2, and the construction of one set of scaffolding is completed. Repeat the above steps to build multiple sets of scaffolding. Finally, to ensure the stability of the scaffolding, workers install wall connecting parts 5 on the steel pipes 1 close to the wall, and clamp them on the wall to firmly connect the steel pipes 1 to the wall, thereby enhancing the overall stability of the scaffolding. At the same time, in order to prevent the scaffolding from shaking during use, workers install diagonal braces 7 between multiple groups of steel pipes 1 away from the wall to form a triangular support structure to further enhance the stability of the scaffolding. Finally, a brace 8 is installed on the steel pipes 1 of the low-level scaffolding away from the wall to ensure that the multi-layer scaffolding has a sufficient support angle during use to prevent the occurrence of swaying.

[0038] When facing a spherical or curved building surface, it is difficult for a conventional square scaffold to fit closely to the wall, resulting in a large distance between the scaffold and the wall, increasing the difficulty of construction and the risk of workers falling. In addition, although the use of a curved scaffold can partially solve the fitting problem, due to its fixed curvature design, it is difficult to adapt to building walls with different curvatures, thereby limiting the adaptability of the curved scaffold. In order to solve this problem, a plurality of slide plates 6 are arranged on the bearing plate 4. When the scaffold needs to be built on the curved building wall, the worker only needs to push the bearing plate 4 to slide forward in the first slide groove 2002 close to the wall. Due to the influence of the curvature of the wall, the order in which the slide plates 6 contact the wall is not consistent. The same results in a difference in sliding distance. When the bearing plate 4 is clamped and fixed on the vertical beam plate 2, the front end of the slide plate 6 can still maintain contact with the curved wall, thereby adapting to walls of different curvatures. This design effectively avoids the generation of an excessive gap between the scaffolding and the wall, which not only reduces the difficulty of construction, but also prevents workers from falling between the scaffolding and the wall. Furthermore, when encountering a raised structure on the curved wall, the slide plate 6 itself is used to push against the wall, so that the slide plate 6 can be adjusted separately when it is pushed against the wall to adapt to the adjustment when the wall is raised. This design allows the scaffold to fit tightly when facing a curved wall with a raised structure, thereby improving the adaptability and safety of the scaffold.

[0039] It is considered that in order to prevent rainwater from accumulating on the supporting board 4 after construction, the water accumulated on the pedal 4001 is discharged downward through the through groove provided on the pedal 4001, so as to prevent the workers from slipping due to the water accumulated on the supporting board 4.

[0040] It is also considered that after the skateboard 6 is added, in order to prevent the skateboard 6 from slipping when the workers step on it, when the skateboard 6 adapts to the curved wall, the workers can adjust it through the bolt 102 located under the load-bearing plate 4. The specific operation is as follows: the worker twists the bolt 102 to gradually embed it into the load-bearing plate 4, and then pushes the locking plate 103 to gradually approach the second slide groove 4002 on the lower side of the load-bearing plate 4. When the extrusion portion 10301 passes through the rectangular hole on the second slide groove 4002 and contacts the skateboard 6, the worker continues to twist the bolt 102 to make the extrusion portion 10301 clamp the skateboard 6, thereby ensuring that the skateboard 6 cannot slide. This design effectively prevents the workers from slipping and falling when stepping on the skateboard 6. At the same time, in the process of the workers carrying the load-bearing plate 4, the locked skateboard 6 can also prevent it from sliding and hitting the workers, further ensuring the safety of the workers.

[0041] It is also taken into consideration that when the skateboard 6 is provided to adapt to the curved wall, the supporting plate 4 is adjusted to avoid the skateboard 6, resulting in a larger hollow space between the skateboard 6 and the supporting plate 4, and then a height difference between the supporting plate 4 and the skateboard 6. When workers step on the supporting plate 4, they are prone to step on the skateboard 6 and fall. Therefore, by providing multiple support plates 101 in the supporting plate 4, during the adjustment of the skateboard 6, the skateboard 6 also synchronously drives the support plates 101 to extend and retract in the supporting plate 4, and then the support plates 101 are used to make up for the height difference between the skateboard 6 and the supporting plate 4, and at the same time make up for the hollow space between the supporting plate 4 and the skateboard 6, so as to avoid workers falling and getting injured when stepping on them.

[0042] Example 2

[0043] On the basis of Example 1, Figure 1 , Figure 2 and Figure 6-Figure 8 As shown, the storage system includes a baffle 201, a protective net 202, a roller 203, an elastic member 205 and a buckle 206; a plurality of elastic members 205 are fixedly connected in each supporting plate 4, and the elastic member 205 is a spring; a baffle 201 is slidably connected in each supporting plate 4; the baffle 201 and the elastic member 205 located in the same supporting plate 4 are fixedly connected; a roller 203 is rotatably connected to the rear side of each baffle 201 through a spiral spring; a protective net 202 is wound on each roller 203; two buckles 206 are fixedly connected to the rear side of each protective net 202, and a locking rod 1002 is provided on all steel pipes 1 located on the rear side.

[0044] A drawstring 204 is also included; a drawstring 204 is fixedly connected to the rear side of each buckle 206 .

[0045] A clamping plate is provided on the rear side of each protective net 202, which is clamped on the rear side of the supporting plate 4 when the protective net 202 is stored, so as to facilitate workers to pull the protective net 202 out of the supporting plate 4, and prevent the roller 203 from over-winding the protective net 202, thereby preventing the pull rope 204 from being rolled into the supporting plate 4.

[0046] Each protective net 202 is woven with metal wires, and the metal wires are used to reduce the weight of the protective net 202, making it easier for workers to carry it.

[0047] In the process of building a scaffold, when the number of scaffolding layers is high, it is necessary to build a safety net on the side of the high-rise scaffolding away from the wall to avoid the risk of workers falling during construction. When laying the safety net, all scaffoldings need to be covered, resulting in a larger safety net as a whole, making it more difficult for workers to lay the safety net, and it is extremely inconvenient to store the safety net later. Therefore, for scaffolding with fewer layers, the protective net 202 can be stored in the carrying plate 4 without being unfolded, which is convenient for the protective net 2 02 can be stored, transported and stored. When it is necessary to lay the protective net 202, the worker only needs to stand on the lower supporting plate 4 and pull the protective net 202 located in the upper supporting plate 4, thereby releasing the protective net 202 wound by the winding roller 203. At this time, the spiral spring in the winding roller 203 is gradually tightened. When the winding roller 203 completely releases the protective net 202, the worker pulls the protective net 202 again toward the locking rod 1002 under the steel pipe 1, thereby pulling the winding roller 203 and the baffle 201 together. The protective net 202 moves backward, thereby stretching the elastic member 205. Finally, the worker only needs to buckle the buckle 206 on the protective net 202 on the locking rod 1002 of the steel pipe 1 to complete the laying of the protective net 202 of the single set of scaffolding, making it more convenient for the workers to lay the protective net 202. At the same time, when the protective net 202 needs to be stored, the buckle 206 on the protective net 202 only needs to be separated from the locking rod 1002 on the steel pipe 1, so that the elastic member 205 loses the restriction of the steel pipe 1, and then rebounds to drive the baffle 201 and the roller 20 3 returns to the initial state, at this time, the worker holds the protective net 202 and slowly brings it back to the carrier plate 4 under the reset of the elastic member 205, and finally the roller 203 rewinds the protective net 202 under the drive of the spiral spring, so that the protective net 202 is completely stored in the carrier plate 4. In the subsequent process of dismantling and transporting the scaffolding by the workers, the protective net 202 stored in the carrier plate 4 does not need additional transportation and disassembly work, making the subsequent disassembly and transportation work more efficient and convenient, and reducing the workload of manual labor.

[0048] It is also taken into consideration that since the overall height of the steel pipe 1 is higher than the height of the workers, it is more difficult for the workers to stretch the protective net 202 in the upper supporting plate 4. In order to facilitate the workers to pull out the protective net 202, a pull rope 204 is added to the buckle 206 of the protective net 202. The workers can raise their hands and hold the pull rope 204 to pull out the protective net 202, thereby avoiding the difficulty for the workers to pull out the protective net 202 due to the steel pipe 1 being too high. At the same time, the setting of the pull rope 204 can also be used to wrap the pull rope 204 around the locking rod 1002 after the buckle 206 buckles the locking rod 1002 for double protection, thereby preventing the protective net 202 from loosening in a windy environment and improving the stability of the protective net 202 during the construction process.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
