Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a scaffold for large-span structure construction. Background Art

[0002] A large number of scaffolds are required during the construction of large-span structures. Scaffolds are a kind of work platform set up to ensure the smooth progress of each construction process. The existing scaffolds are not very convenient to disassemble and assemble, so it takes a lot of time to disassemble and assemble, which will delay the construction progress. In addition, the existing scaffolds have many parts after being disassembled, so it is very easy for a part to be lost when the scaffolds are disassembled.

[0003] For example, a Chinese invention patent disclosed in the publication number of Chinese patent CN109113317B and the authorization announcement date of December 8, 2020 discloses a scaffold for construction, including a hollow plate, a No. 1 support column, and a No. 2 support column. The lower end of the hollow plate is clamped with a No. 1 support beam and a No. 2 support beam on both sides, and the No. 1 support beam and the No. 2 support beam are clamped with connecting beams on both sides of the lower ends. The two ends of the connecting beam pass through the No. 1 support column and the No. 2 support column respectively. A connecting ring is fixedly connected to one side of the connecting beam, and a pull rope is tied to the outer surface of the connecting ring.

[0004] However, in actual use, the above-mentioned scaffolding is provided with too many parts, so that people will increase the operation steps when disassembling and assembling, which will consume a lot of time and affect the construction progress. In addition, since the above-mentioned scaffolding has many parts, when people disassemble the scaffolding and all the parts are piled together, it is very easy for parts to be lost, so that the scaffolding cannot be assembled smoothly.

[0019] In this embodiment, when the scaffolding needs to be installed, the two support rods are first pulled outward, and the angle between the first pedal 1 and the second pedal 2 will increase. When the first pedal 1 and the second pedal 2 are both in a horizontal state, the baffle 4 will overlap the first groove 5, and the first pedal 1 and the second pedal 2 will not continue to fold downward. In addition, when the first pedal 1 and the second pedal 2 are both in a horizontal state, the first support rod 6 and the second support rod 7 will also be in a horizontal state to improve the stability of the scaffolding. When people need to recycle the scaffolding, the two support frames 3 are brought close to each other, and the first pedal 1 and the second pedal 2 and the first support rod 6 and the second support rod 7 are folded together, so that the scaffolding can be quickly recycled.

[0020] like Figure 1-3 As shown, the second support rod 7 is located at one end of the first support rod 6 and is fixedly connected to the first connecting block 8. The first support rod 6 is located at one end of the second support rod 7 and is provided with a second groove 9 that cooperates with the first connecting block 8. The first connecting block 8 is movably connected to the second groove 9. In this embodiment, when the first support rod 6 and the second support rod 7 are in a horizontal state, the first connecting block 8 will overlap with the second groove 9, and the first support rod 6 and the second support rod 7 will not continue to fold downward.

[0021] like Figure 1-3As shown, the first support rod 6 is located at both ends of the second groove 9 and is fixedly connected with the second connecting blocks 10 respectively. The first connecting block 8 and the second connecting block 10 are both provided with matching through holes 11, and a fixing pin 12 is movably inserted in the through hole 11. In this embodiment, when the first support rod 6 and the second support rod 7 are in a horizontal state, the through holes on the first connecting block 8 and the second connecting block 10 will be aligned. At this time, the fixing pin 12 is inserted into the through hole 11, so that the structure of the entire scaffolding will be very stable.

[0022] like Figure 1-3 As shown, a connecting rope 13 is provided at one end of the first support rod 6, and one end of the connecting rope 13 is fixedly connected to the fixing pin 12. In this embodiment, the fixing pin 12 is always connected to the first support rod 6 through the design of the connecting rope 13, so that the fixing pin 12 will not be lost.

[0023] like Figure 1 As shown, four fixing columns 14 are fixedly connected to the top of the support frame 3, and four sleeves 15 are fixedly connected to the bottom of the support frame 3. In this embodiment, when the construction height is high, multiple scaffolds can be installed on the scaffold. During operation, the sleeve 15 at the bottom of the scaffold to be installed is aligned with the supporting column at the top of the scaffold and installed, thereby increasing the height of the scaffold. In addition, through the design of the sleeve 15, people can install rollers at the bottom of the scaffold to facilitate the movement of the scaffold.

[0024] Working principle: during use, when the scaffolding needs to be installed, first pull the two support rods outward, then the angle between the first pedal 1 and the second pedal 2 will increase, and when the first pedal 1 and the second pedal 2 are both in a horizontal state, the baffle 4 will overlap into the first groove 5, and the first pedal 1 and the second pedal 2 will not continue to fold downward, and when the first pedal 1 and the second pedal 2 are both in a horizontal state, the first support rod 6 and the second support rod 7 will also be in a horizontal state, and the first connecting block 8 will overlap into the second groove 9, and the first support rod 6 and the second support rod 7 will not continue to fold downward, and at this time, the through holes provided on the first connecting block 8 and the second connecting block 10 will be aligned, and the first support rod 6 will be aligned. The fixing pin 12 connected by the connecting rope 13 at the end is inserted into the through hole 11, so that the structure of the whole scaffolding will be very stable. When the construction height is high, multiple scaffoldings can be installed on the scaffolding. During operation, the sleeve 15 at the bottom of the scaffolding to be installed is aligned with the supporting column at the top of the scaffolding and installed, so that the height of the scaffolding is increased. In addition, through the design of the sleeve 15, people can install rollers at the bottom of the scaffolding to facilitate the movement of the scaffolding. When people need to recycle the scaffolding, first remove the fixing pin 12 from the through hole 11, and then move the two support frames 3 close to each other, so that the first pedal 1 and the second pedal 2 and the first support rod 6 and the second support rod 7 are folded together, so that the scaffolding can be quickly recycled.
