Description

Technical Field

[0001] The utility model specifically relates to a tool-type cantilever steel pipe scaffold, belonging to the technical field of cantilever scaffolds. Background Art

[0002] Cantilever scaffolding is a commonly used form of scaffolding in construction. When constructing traditional scaffolding, the upper scaffolding needs to rely on the lower foundation to be constructed, while the cantilever scaffolding uses the main body of the building as the lower foundation, or even relies entirely on the main body of the building as support, which can play a better role in safety protection in construction and decoration projects.

[0003] For example, the Chinese invention patent application document with publication number CN105298098A discloses a cantilevered fastener steel pipe scaffolding, including a horizontal steel beam, a large cross bar and vertical bars, one end of the horizontal steel beam is welded with a steel plate and fixedly connected to the wall through a locking piece, a large cross bar and a longitudinal bar are horizontally arranged on the top of the horizontal steel beam, and vertical bars are vertically arranged on the top of the horizontal steel beam, and the large cross bar, longitudinal bar and vertical bars are installed together by a steel pipe clamp.

[0004] The above-mentioned scaffolding can be erected on any floor with flexible layout; the setting of the support rod increases the connection strength and ensures the overall stability and firmness; the handrails are arranged on the scaffolding board to ensure the safety of the users.

[0005] The construction of cantilever scaffolding not only relies on crossbeams for support, but also requires the use of diagonal stay mechanisms or diagonal bracing mechanisms for joint support. Traditional scaffolding relies on steel pipes and snap-on fixings for clamping steel pipes for one-to-one docking, and steel pipes are used to build the main body of the protective frame. Generally, comprehensive protection usually requires more complex component assembly, and too many components increase the difficulty of construction and extend the construction period. Therefore, for the existing cantilever steel pipe scaffolding, it is very necessary to simplify the assembly steps and reduce the labor operations of workers, and thus the utility model is proposed.

The assembly chassis is fixedly connected to the bearing beam through assembly bolts. An upper retaining piece is fixed on the outer wall of the vertical rod member, and the upper retaining piece is located above the upper surface of the bearing beam. The vertical rod member and the bearing beam are integrally formed with less disassembly.

[0009] The connecting structure includes a ring body part, a side plate part is fixed on the side wall of the ring body part, a disassembly plate is fixed on the side plate part through a fixing bolt, and the disassembly plate is fixed to the protective arm. An escape notch corresponding to the outer shape of the limiting block is opened on the ring body part. The connecting structure and the protective arm are integrally formed with less disassembly.

[0010] An arc-shaped track frame is fixed on the outer wall of the ring body part, a seat body block is slidably clamped on the arc-shaped track frame, the side wall of the seat body block is attached to the outer wall of the ring body part, and a lower ear plate is fixed at the bottom of the seat body block.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 6As shown in the figure, a tool - type cantilever steel pipe scaffold includes a bearing beam 1. One end of the bearing beam 1 is fixed on the building main body, and the bearing beam 1 is used to bear the main gravity. On the other end of the bearing beam 1, a vertical rod member 2 is installed. A support ring 201 is fixed on the outer wall of the upper part of the vertical rod member 2, and a limit block 202 is fixed on the side wall of the top of the vertical rod member 2. A connecting structure 3 is sleeved on the upper part of the vertical rod member 2. A protective arm 4 is fixed on the connecting structure 3. A joint mechanism 5 is rotatably installed at the end of the protective arm 4, and the joint mechanism 5 is used to fixedly connect the positions of the protective arms 4 on both sides.

[0025] An assembly hole is opened at the end of the bearing beam 1. The bottom of the vertical rod member 2 passes through the assembly hole, and an assembly chassis 203 is fixed at the bottom of the vertical rod member 2. The assembly chassis 203 is fixedly connected to the bearing beam 1 through assembly bolts. An upper retaining piece is fixed on the outer wall of the vertical rod member 2, and the upper retaining piece is located above the upper surface of the bearing beam 1. The vertical rod member 2 and the bearing beam 1 are less likely to be disassembled as a whole.

[0026] The connecting structure includes a ring body part 301. A side plate part 302 is fixed on the side wall of the ring body part 301. A disassembly plate 303 is fixed on the side plate part 302 through a fixing bolt, and the disassembly plate 303 is fixed to the protective arm 4. An escape notch 304 corresponding to the outer shape of the limit block 202 is opened on the ring body part 301. The connecting structure and the protective arm 4 are less likely to be disassembled as a whole.

[0027] An arc - shaped track frame 305 is fixed on the outer wall of the ring body part 301. A seat body block 306 is slidably clamped on the arc - shaped track frame 305. The side wall of the seat body block 306 is attached to the outer wall of the ring body part 301. A lower ear plate is fixed at the bottom of the seat body block, and a positioning bolt 307 is assembled on the lower ear plate through a threaded hole. One end of the positioning bolt 307 passes through the lower ear plate and is close to the outer wall of the ring body part 301.

[0028] Two connecting structures 3 are sleeved above the support ring 201, but the corresponding seat body block 306 structures are mirror - flipped. The seat body blocks 306 arranged on the outer walls of the corresponding ring body parts 301 are close to each other, and part of the seat body blocks 306 respectively extend to one side of the opposite ring body part 301. The connecting structures 3 are respectively connected to the protective arms 4 in two directions, so as to facilitate the formation of protection on one side. After the connecting structure 3 is sleeved in place, adjust the position of the seat body block 306, and then fix it through the positioning bolt 307. The position of the seat body block 306 determines the maximum limit of the included angle between the protective arms 4 on both sides after docking. The advantage of this is that after adjusting and limiting the opening angle between the protective arms 4, a better preset shape can be formed, avoiding the excessive flexibility of the protective arms 4 and thus being difficult to control. At the same time, the need for fixing a single protective arm 4 is reduced, and the usage method is more flexible.

[0029] The top of the vertical rod member 2 is provided with a clamping hole, and an extension rod member 6 located above the vertical rod member 2 is inserted and installed through the clamping hole. The upper part of the extension rod member 6 is also provided with a support ring 201 and a limit block 202. When it is necessary to expand the protection range, the extension rod member 6 can be added.

[0030] The combined mechanism 5 includes a rotary joint part 501 fixed at one end of the protective arm 4. A semi-cylindrical shell 502 is horizontally rotatably installed on the rotary joint part 501. A threaded part is provided on the outer wall of the semi-cylindrical shell 502. The semi-cylindrical shells 502 at one end of the protective arm 4 can form a complete cylinder. A combined fixing cylinder 503 is installed outside the semi-cylindrical shell 502 by a threaded method. An intermediate pipe 7 is clamped and assembled between the semi-cylindrical shells 502. When it is necessary to connect the intermediate pipe 7, the combined fixing cylinder 503 should be removed first, then the intermediate pipe 7 is inserted into the semi-cylindrical shell 502, and then the combined fixing cylinder 503 is reinstalled.

[0031] This scaffolding needs to be assembled and used with multiple independent units. Repeatedly setting this scaffolding along the outer wall of the building can form a better protection effect. After the fixed bearing beam 1 is completed, the vertical rod member 2 with the protective arm 4 is connected, and the protective arm 4 is rotated to a suitable position so that the protective arms 4 can be butted against each other, and at the same time, a side safety protection is formed. Then, the protective arms 4 are connected by the combined mechanism 5 to form a protection, and the installation is very fast. Subsequently, a walking partition can be added according to requirements.

[0032] During use, the vertical rod member 2 is fixed on the bearing beam 1. During use, the connecting structure 3 needs to be sleeved outside the vertical rod member 2 through the limit block 202 first, and then the protective arm 4 is rotated to the outside of the protection. The seat blocks 306 can limit each other's positions to prevent the protective arm 4 from opening too much. Then, the semi-cylindrical shells 502 are butted against each other. Since both ends of the protective arm 4 are restricted, the protective arm 4 can adopt a telescopic rod form, so as to expand the protection range.
