Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a cantilever scaffold support with adjustable length. Background Art

[0002] Cantilever scaffolding is a type of scaffolding commonly used in high-rise building construction. It is mainly supported by the structure of the building. Usually, cantilever beams or cantilever structures are set at the edge of each floor, and then the scaffolding is fixed to these cantilever structures. The advantage of this is that it can reduce the occupation of ground space while providing the necessary working platform and safety protection for construction.

[0003] The cantilever scaffolding support has an important influence on the overall stability of the scaffolding project. When constructing a cantilever scaffolding, due to the influence of some protruding structures such as balcony panels and air-conditioning outdoor unit panels in the building structure, there are usually supports of different lengths. The two commonly used lengths are 1.4 m and 1.9 m.

[0004] However, for reusable cantilever scaffolding supports, conventional supports of two lengths need to be made separately, and it is impossible to achieve the conversion of two lengths on one support. For example, the scaffolding supports purchased during the first batch of construction may not meet the quantity requirements of different lengths for the next construction, resulting in idle supports, and the need to purchase scaffolding supports of the missing length specifications, which will increase the cost of the project and affect the project efficiency, and needs to be improved. Summary of the invention

[0008] In a preferred example, the present invention can be further configured as follows: the vertical adjustment support assembly includes a first vertical perforated steel plate and a second vertical perforated steel plate, the upper end of the first vertical perforated steel plate is welded and fixed to the horizontal long support steel plate, the lower end of the second vertical perforated steel plate is rotatably connected to the oblique long support steel plate by bolts, and the holes on the first vertical perforated steel plate and the second vertical perforated steel plate are used to communicate with each other and for bolts to pass through to achieve connection.

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a cantilever scaffold support with adjustable length includes a vertical supporting angle steel 1, a transverse long supporting steel plate 2, a transverse short supporting steel plate 3, an oblique long supporting steel plate 4 and an oblique short supporting steel plate 5.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the vertical support angle steel 1 is vertically arranged on the building wall, and the transverse long support steel plate 2 is horizontally welded and fixed to the upper end of the vertical support angle steel 1. The transverse short support steel plate 3 is rotatably connected to the end of the transverse long support steel plate 2 away from the vertical support angle steel 1 by bolts. When the oblique long support steel plate 4 is turned upward, the oblique long support steel plate 4 is fixed to the transverse long support steel plate 2 by bolts.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the oblique long support steel plate 4 is obliquely arranged at the upper end of the vertical support angle steel 1, and is rotatably connected to the vertical support angle steel 1 by bolts. The oblique short support steel plate 5 is rotatably connected to the end of the oblique long support steel plate 4 away from the vertical support angle steel 1 by bolts. The ends of the transverse short support steel plate 3 and the oblique short support steel plate 5 that are close to each other are fixed by bolt connection.

[0020] When it is necessary to switch the cantilever scaffold support from 1.9 m to 1.4 m, remove the bolts between the transverse long support steel plate 2 and the transverse short support steel plate 3, and then remove the bolts between the oblique long support steel plate 4 and the oblique short support steel plate 5.

[0021] Then, the oblique long supporting steel plate 4 is controlled to flip upward so that the end positions of the oblique long supporting steel plate 4 and the transverse long supporting steel plate 2 are in contact with each other. Then, bolts are used to penetrate the end positions of the oblique long supporting steel plate 4 and the transverse long supporting steel plate 2 in sequence to achieve the connection and fixation of the end positions of the oblique long supporting steel plate 4 and the transverse long supporting steel plate 2, thereby realizing the switching of one of the states of the cantilever scaffolding support.

[0022] When it is necessary to switch the cantilever scaffolding support from 1.4 m to 1.9 m, remove the bolts at the end positions of the oblique long support steel plate 4 and the transverse long support steel plate 2, then use bolts to connect the transverse long support steel plate 2 and the transverse short support steel plate 3, and then use bolts to connect the oblique long support steel plate 4 and the oblique short support steel plate 5.

[0023] Then, the oblique long supporting steel plate 4 is controlled to flip downward, so that the end position of the oblique short supporting steel plate 5 is in contact with the end position of the transverse short supporting steel plate 3, and then bolts are used to penetrate the end positions of the oblique short supporting steel plate 5 and the transverse short supporting steel plate 3 in sequence to realize the switching of the cantilever scaffolding support to another state.

[0024] Therefore, by providing freely disassembled and installed transverse short support steel plates 3 and oblique short support steel plates 5, and cooperating with the rotatable oblique long support steel plates 4, the length adjustment of the entire cantilever scaffolding support can be realized, and free switching between the two lengths of 1.4 m and 1.9 m can be realized, which meets the needs of most construction projects for cantilever scaffolding supports, reduces project cost and improves project efficiency.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a vertical adjustment support assembly 6 and an oblique adjustment support assembly 7 are arranged between the transverse long support steel plate 2 and the oblique long support steel plate 4, so as to realize the connection support between the transverse long support steel plate 2 and the oblique long support steel plate 4, thereby improving the structural strength and load-bearing capacity of the entire cantilever scaffolding support.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the vertical adjustment support assembly 6 is vertically arranged and connects the middle positions of the transverse long support steel plate 2 and the oblique long support steel plate 4. The vertical adjustment support assembly 6 includes a first vertical perforated steel plate 61 and a second vertical perforated steel plate 62.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the upper end of the first vertical perforated steel plate 61 is welded and fixed to the transverse long support steel plate 2, and the lower end of the second vertical perforated steel plate 62 is rotatably connected to the oblique long support steel plate 4 by bolts. The holes on the first vertical perforated steel plate 61 and the second vertical perforated steel plate 62 are used to communicate with each other and are used for bolts to penetrate and connect.

[0028] When it is necessary to switch the cantilever scaffolding support from 1.4 m to 1.9 m or from 1.9 m to 1.4 m, the bolts connecting the first vertical perforated steel plate 61 and the second vertical perforated steel plate 62 can be removed, and then the second vertical perforated steel plate 62 can be controlled to rotate synchronously following the rotation of the oblique long support steel plate 4, and the holes of the first vertical perforated steel plate 61 and the second vertical perforated steel plate 62 can be aligned to achieve the connection and fixation of the first vertical perforated steel plate 61 and the second vertical perforated steel plate 62, thereby achieving free adjustment of the length of the vertical adjustment support assembly 6, thereby satisfying the free switching of two different length states of the cantilever scaffolding support.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the lower end of the oblique adjustment support assembly 7 is connected to the middle position of the oblique long support steel plate 4, and the upper end is inclined upward and away from the vertical adjustment support assembly 6 to connect the horizontal long support steel plate 2. The oblique adjustment support assembly 7 has a first oblique perforated steel plate 71 and a second oblique perforated steel plate 72.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the upper end of the first oblique perforated steel plate 71 is welded and fixed to the transverse long supporting steel plate 2, and the lower end of the second oblique perforated steel plate 72 is rotatably connected to the oblique long supporting steel plate 4 by bolts. The holes on the first oblique perforated steel plate 71 and the second oblique perforated steel plate 72 are used to communicate with each other and are used for bolts to penetrate and connect.

[0031] When it is necessary to switch the cantilever scaffolding support from 1.4 m to 1.9 m or from 1.9 m to 1.4 m, the bolts connecting the first oblique perforated steel plate 71 and the second oblique perforated steel plate 72 can be removed, and then the second oblique perforated steel plate 72 can be controlled to rotate synchronously following the rotation of the oblique long support steel plate 4, and the holes of the first oblique perforated steel plate 71 and the second oblique perforated steel plate 72 can be aligned to achieve the connection and fixation of the first oblique perforated steel plate 71 and the second oblique perforated steel plate 72, thereby achieving free adjustment of the length of the oblique adjustment support assembly 7, thereby satisfying the free switching of two different length states of the cantilever scaffolding support.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an oblique fixed reinforcement plate 8 is arranged between the vertical supporting angle steel 1 and the transverse long supporting steel plate 2, the lower end of the oblique fixed reinforcement plate 8 is welded and fixed to the lower end of the vertical supporting angle steel 1, and the upper end is welded and fixed to the transverse long supporting steel plate 2, and is connected to the first oblique perforated steel plate 71.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an oblique movable reinforcement plate 9 is arranged between the transverse long supporting steel plate 2 and the end of the oblique long supporting steel plate 4 away from the vertical supporting angle steel 1, the lower end of the oblique movable reinforcement plate 9 is fixed to the middle position of the oblique long supporting steel plate 4 by bolts, and the upper end is inclined upward and away from the vertical supporting angle steel 1 and connected to the transverse long supporting steel plate 2 by bolts.

[0034] Therefore, by respectively arranging an oblique fixed reinforcement plate 8 and an oblique movable reinforcement plate 9 between the vertical supporting angle steel 1, the transverse long supporting steel plate 2 and the oblique long supporting steel plate 4, support between the vertical supporting angle steel 1, the transverse long supporting steel plate 2 and the oblique long supporting steel plate 4 can be achieved, thereby improving the structural strength and load-bearing capacity of the entire cantilever scaffolding support.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the transverse short supporting steel plate 3, the oblique short supporting steel plate 5 and the oblique movable reinforcing plate 9 are attached to the back side of the transverse long supporting steel plate 2 after being disassembled, and the transverse long supporting steel plate 2 is penetrated by a plurality of mounting holes 21 for bolts to pass through the connection positions of the transverse short supporting steel plate 3, the oblique short supporting steel plate 5 and the oblique movable reinforcing plate 9.

[0036] When it is necessary to switch the cantilever scaffold support from 1.9 m to 1.4 m, the transverse short support steel plate 3 and the oblique short support steel plate 5 can be flipped to be horizontal with the transverse long support steel plate 2, and the transverse short support steel plate 3 and the oblique short support steel plate 5 are located on the back side of the transverse long support steel plate 2. Then, the bolts originally connected to the oblique short support steel plate 5 are passed through the corresponding mounting holes 21 to fix the transverse short support steel plate 3 and the oblique short support steel plate 5. At the same time, the oblique movable reinforcement plate 9 can be disassembled, and the bolts originally connected to the oblique movable reinforcement plate 9 are passed through the corresponding mounting holes 21 to fix the oblique movable reinforcement plate 9.

[0037] Therefore, by opening a mounting hole 21 on the transverse long supporting steel plate 2, the disassembled transverse short supporting steel plate 3, the oblique short supporting steel plate 5 and the oblique movable reinforcement plate 9 can be attached to the back side of the transverse long supporting steel plate 2 to avoid loss of components. At the same time, the total length of the cantilever scaffolding support can be quickly adjusted to improve engineering efficiency.

[0038] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
