Description

Technical Field

[0001] The invention relates to the field of construction engineering, and in particular to a cantilever scaffold support with fine-adjustable height. 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 impact on the overall stability of the scaffolding project. When constructing cantilever scaffolding, the consistent height of the scaffolding on the same level is crucial to safety and overall stability.

[0004] If there is a slight height difference in the scaffolding, it will cause local stress concentration, which will cause the scaffolding system to tilt, and in severe cases, it will cause the scaffolding to collapse. As the scaffolding support that bears the entire weight, the height difference requirement is very high.

[0005] However, in the actual construction process of the scaffolding, when handling the installed scaffolding with height difference, a certain supporting structure is usually added. This operation method is more troublesome and also increases the construction cost, which needs to be improved. Summary of the invention

[0006] In view of the deficiencies in the prior art, the object of the present invention is to provide a cantilever scaffold support with fine-tunable height, which can adjust the existing height difference through simple operation to meet the overall balance of the scaffold.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: A cantilever scaffold support with fine-adjustable height, comprising: Vertical support angle steel is set vertically on the building wall; A transverse supporting angle steel is horizontally arranged at the upper end of the vertical supporting angle steel; An oblique support angle steel, one end of which is arranged at the lower end of the vertical support angle steel, and the other end of which extends obliquely upward and is fixed to the transverse support angle steel; A pair of adjustment mechanisms are arranged at the upper and lower ends of the vertical support angle steel and are used to control the vertical sliding of the transverse support angle steel and the oblique support angle steel respectively.

[0008] In a preferred example, the present invention can be further configured as follows: the adjustment mechanism includes a thickened steel block, a fixed open-hole steel block, an adjusting bolt and a fastener, the thickened steel block is horizontally arranged on the lower end side wall of the transverse supporting angle steel or the oblique supporting angle steel close to one end of the vertical supporting angle steel, the fixed open-hole steel block is arranged on the side wall of the vertical supporting angle steel and is located below the thickened steel block, the adjusting bolt is vertically threadedly connected to the fixed open-hole steel block and is used to push the thickened steel block to slide vertically, and the fastener is used to fix the transverse supporting angle steel and the oblique supporting angle steel.

[0009] In a preferred example, the present invention can be further configured as follows: the fastener includes a fastening bolt and a nut, the fastening bolt horizontally penetrates the vertical supporting angle steel, the nut is threadedly connected to the fastening bolt, and the transverse supporting angle steel and the oblique supporting angle steel are vertically provided with long sliding holes, the sliding holes are located above the thickened steel block, and are used for the fastening bolt to pass through and vertically slide.

[0010] In a preferred example, the present invention can be further configured as follows: a reinforcing steel block located above the sliding hole is horizontally arranged on both the transverse supporting angle steel and the oblique supporting angle steel.

[0011] In a preferred example, the present invention can be further configured as follows: a plurality of reinforcing support steel plates are welded and fixed between the transverse support angle steel and the oblique support angle steel, and the plurality of reinforcing support steel plates are arranged in an N shape.

[0012] In a preferred example, the present invention can be further configured as follows: an infrared transmitter is provided at the upper end of the vertical support angle steel, and a receiving plate for irradiation by the infrared transmitter is vertically provided at one end of the lateral support angle steel away from the vertical support angle steel, and scale lines are provided on the receiving plate.

At the same time, a simple adjustment method is adopted to realize height adjustment, eliminate height differences, and eliminate possible dangers of the scaffolding; 2. By setting reinforcing steel blocks on the transverse support angle steel and the diagonal support angle steel, the structural strength and bearing capacity of the stress-bearing positions of the transverse support angle steel and the diagonal support angle steel are increased to ensure the stability of the entire cantilever scaffolding support; 3. By setting up reinforced supporting steel plates, the structural strength and pressure-bearing capacity of the entire cantilever scaffolding support are increased to ensure the stable use of the cantilever scaffolding support.

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

[0017] like Figure 1 , Figure 2 , Figure 3 As shown, a cantilever scaffold support with fine-adjustable height includes a vertical support angle steel 1, a horizontal support angle steel 2, an oblique support angle steel 3 and a pair of adjustment mechanisms 4.

[0018] like Figure 2 , Figure 3 As shown, the vertical support angle steel 1 is vertically arranged on the building wall, the transverse support angle steel 2 is horizontally arranged at the upper end of the vertical support angle steel 1, and one end of the oblique support angle steel 3 is arranged at the lower end of the vertical support angle steel 1, and the other end is obliquely extended upward and welded to the transverse support angle steel 2.

[0019] like Figure 2 , Figure 3 As shown, a plurality of reinforcing support steel plates 5 are welded and fixed between the transverse support angle steel 2 and the oblique support angle steel 3. The plurality of reinforcing support steel plates 5 are arranged in an N shape to increase the structural strength and pressure bearing capacity of the entire cantilever scaffolding support and ensure the stable use of the cantilever scaffolding support.

[0020] like Figure 2 , Figure 3 As shown, a pair of adjustment mechanisms 4 are arranged at the upper and lower ends of the vertical support angle steel 1, and are respectively used to control the vertical sliding of the transverse support angle steel 2 and the oblique support angle steel 3, so as to realize the position adjustment of the entire cantilever scaffolding support.

[0021] like Figure 2 , Figure 3As shown, an infrared transmitter 6 is disposed at the upper end of the vertical support angle steel 1, and a receiving plate 7 for irradiation by the infrared transmitter 6 is vertically disposed at one end of the transverse support angle steel 2 away from the vertical support angle steel 1, and a scale line 8 is disposed on the receiving plate 7.

[0022] When installing and fixing the cantilever scaffolding support, the vertical support angle steel 1 can be fixed to the building wall with bolts, and then the infrared transmitter 6 is turned on to make the light spot directly shine on the receiving plate 7. At this time, the initial installation position of the cantilever scaffolding support can be determined by the position of the light spot on the receiving plate 7 and the scale line 8 on the receiving plate 7.

[0023] If there is a slight height difference after the cantilever scaffolding support is installed, the light spot will change on the receiving plate 7, thereby intuitively reflecting the actual height position of the cantilever scaffolding support. Then the adjustment mechanism 4 can be used to achieve synchronous adjustment of the height positions of the transverse support angle steel 2 and the oblique support angle steel 3, thereby achieving position adjustment of the entire cantilever scaffolding support.

[0024] During the adjustment process of the transverse supporting angle steel 2 and the oblique supporting angle steel 3, the position of the light spot is continuously observed to eliminate the slight differences between the two end points on the same scaffold and the supports on the same layer of scaffolding, thereby ensuring the overall stability and safety of the scaffolding project. At the same time, a simple adjustment method is used to achieve height adjustment, eliminate height differences, and eliminate possible dangers of the scaffolding.

[0025] like Figure 2 , Figure 3 As shown, the adjustment mechanism 4 includes a thickened steel block 41, a fixed perforated steel block 42, an adjustment bolt 43 and a fastener 44. The thickened steel block 41 is horizontally arranged on the lower end side wall of the lateral support angle steel 2 or the oblique support angle steel 3 close to one end of the vertical support angle steel 1, and the fixed perforated steel block 42 is arranged on the side wall of the vertical support angle steel 1 and is located below the thickened steel block 41. The adjustment bolt 43 is vertically threadedly connected to the fixed perforated steel block 42 and is used to push the thickened steel block 41 to slide vertically.

[0026] like Figure 2 , Figure 3 As shown, the fastener 44 is used to fix the transverse supporting angle steel 2 and the oblique supporting angle steel 3 , and the fastener 44 includes a fastening bolt 45 and a nut 46 .

[0027] like Figure 2 , Figure 3 As shown, the fastening bolt 45 horizontally penetrates the vertical support angle steel 1, and the nut 46 is threadedly connected to the fastening bolt 45. The transverse support angle steel 2 and the oblique support angle steel 3 are vertically provided with a long strip sliding hole 47, which is located above the thickened steel block 41 and is used for the fastening bolt 45 to pass through and slide vertically.

[0028] When it is necessary to control the transverse support angle steel 2 and the diagonal support angle steel 3 to slide in the vertical direction, the fastening bolts 45 and nuts 46 can be loosened first, and then the adjusting bolts 43 can be controlled to move forward or rotate. At this time, the adjusting bolts 43 can push the transverse support angle steel 2 and the diagonal support angle steel 3 to move upward, and can also release the support for the transverse support angle steel 2 and the diagonal support angle steel 3, so that the transverse support angle steel 2 and the diagonal support angle steel 3 automatically move downward under their own gravity, thereby realizing convenient and rapid adjustment of the height position of the transverse support angle steel 2 and the diagonal support angle steel 3. After the transverse support angle steel 2 and the diagonal support angle steel 3 are in the appropriate position, the nuts 46 are tightened, and the transverse support angle steel 2 and the diagonal support angle steel 3 are fixed by the cooperation of the fastening bolts 45 and the nuts 46, so as to ensure the stability of the transverse support angle steel 2 and the diagonal support angle steel 3 during operation.

[0029] like Figure 2 , Figure 3 As shown, a reinforcing steel block 9 located above the sliding hole 47 is horizontally arranged on both the transverse supporting angle steel 2 and the oblique supporting angle steel 3 .

[0030] Because holes are opened on the transverse support angle steel 2 and the diagonal support angle steel 3, the structural strength will be weakened accordingly, and the end positions of the transverse support angle steel 2 and the diagonal support angle steel 3 are the main stress-bearing parts, so reinforcing steel blocks 9 are arranged at this position to increase the structural strength and bearing capacity of the stress-bearing positions of the transverse support angle steel 2 and the diagonal support angle steel 3, thereby ensuring the stability of the entire cantilever scaffolding support.

[0031] 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.
