Technical Field

[0001] This invention relates to the field of building construction, and in particular to a fixing device for the connection position of cantilevered scaffolding and steel profiles. Background Technology

[0002] With the continuous development and progress of my country's construction industry, in order to meet social needs, people have begun to build more and more high-rise buildings. Scaffolding, as a workplace and transportation channel set up for high-altitude workers, is indispensable in the construction of high-rise buildings.

[0003] The bottom steel sections of cantilevered scaffolding are the main load-bearing structure connecting the upper scaffolding, and their stability and safety are crucial to the safety and stability of the entire scaffolding system. However, in current installation processes, due to the lack of clear specifications for the fixing methods of the horizontal and vertical steel sections at the bottom of cantilevered scaffolding, many construction companies use rather arbitrary methods, sometimes even requiring drilling holes in the steel sections for fixing. This could pose significant safety hazards and affect the safety and stability of the cantilevered scaffolding, and needs to be improved. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a fixing device for the connection between cantilevered scaffolding and steel profiles, which improves safety and stability.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a fixing device for the connection position of a cantilevered scaffold and a steel frame, comprising: Horizontal steel sections are arranged horizontally and at intervals on the building facade; Longitudinal steel sections, with horizontal crossbeams resting on multiple transverse steel sections; The transverse fixing frame includes a pair of C-shaped lower supports with openings facing away from each other and abutting against the web and upper and lower flanges of the transverse steel section. Meanwhile, the upper end of the lower supports extends horizontally outward to the outside of the upper flange. The longitudinal fixing frame includes a pair of C-shaped upper supports with openings facing away from each other and abutting against the web and upper and lower flanges of the longitudinal steel section, while the lower end of the upper support extends horizontally outward to the outside of the lower flange. The upper end of the upper support is bent and provided with a clamping plate for holding the upper wing plate. A pair of clamping plates abut against each other. Each clamping plate is provided with a semi-circular insert plate. A pair of insert plates are interlocked and inserted into the end position of the cantilever scaffold. Bolt fasteners are distributed at the four corners of the lower bracket and the upper bracket at their respective ends that are close to each other.

[0006] In a preferred embodiment, the present invention may be further configured such that: a hook is provided on one side of the insert plate, and a retaining ring is provided on the other side for the hook to pass through.

[0007] In a preferred embodiment, the present invention may be further configured such that: a pair of sliding sleeves are fitted on the longitudinal steel section, and a positioning tube is vertically arranged on the sliding sleeve, the positioning tube being inserted into the end of the cantilever scaffold.

[0008] In a preferred embodiment, the present invention may be further configured such that: the sliding sleeve includes a sleeve and side plates, the sleeve is slidably sleeved on the upper wing plate of the longitudinal steel section, and the side plates are disposed on both sides of the sleeve and clamp both sides of the web of the longitudinal steel section.

[0009] In a preferred embodiment, the present invention may be further configured such that: an amplitude processor is provided on the outer side wall of the lower support, an amplitude sensing alarm and an amplitude data display screen are provided on the side of the amplitude processor, and a dual-axis vibration pickup is provided on the side wall of the amplitude processor.

[0010] In a preferred embodiment, the present invention may be further configured such that: a transverse strain gauge is provided at the lower end face of the transverse steel section, a strain processor is provided below the amplitude processor, and a strain sensing alarm and a strain data display screen are provided beside the strain processor.

[0011] In a preferred embodiment, the present invention may be further configured such that: a waterproof junction box is provided on the outer side wall of the lower support, the waterproof junction box is distributed on both sides of the amplitude processor and extends to the lower end face of the transverse steel.

By setting up horizontal and vertical fixing frames, the horizontal and vertical steel sections are clamped together, and bolt fasteners are used to connect and fix the horizontal and vertical fixing frames, thereby realizing the connection between the steel section and the cantilever scaffold. This avoids the need for drilling holes in the steel section for anchoring, achieving non-destructive anchoring, and accurately positioning the reasonable anchoring position of the cantilever scaffold. This improves the safety and stability of the anchoring position of the cantilever scaffold and the steel section, and is highly practical. 2. By adding devices to the horizontal and vertical fixed frames that can monitor the horizontal and vertical amplitude and strain of the cantilevered scaffold in real time, it is possible to provide early warning of the overturning of the cantilevered scaffold, thereby improving the safety and stability of the cantilevered scaffold in the suspended state.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, a fixing device for the connection position of a cantilever scaffold and a steel section includes a transverse steel section 1, a longitudinal steel section 2, a transverse fixing frame 3, a longitudinal fixing frame 4, and bolt fasteners 5.

[0017] like Figure 1 As shown, the transverse steel sections 1 are horizontally and spaced apart on the building facade, and the longitudinal steel sections 2 are horizontally supported on multiple transverse steel sections 1 and are used to connect the cantilevered scaffolding.

[0018] like Figure 1 , Figure 2 As shown, the transverse fixing frame 3 includes a pair of C-shaped lower supports 31 with openings facing away from each other and abutting against the web and upper and lower wing plates of the transverse steel 1. At the same time, the upper end of the lower support 31 extends horizontally outward to the outside of the upper wing plate.

[0019] like Figure 1 , Figure 2 As shown, the longitudinal fixing frame 4 includes a pair of C-shaped upper supports 41 with openings facing away from each other and abutting against the web and upper and lower flanges of the longitudinal steel 2. At the same time, the lower end of the upper support 41 extends horizontally outward to the outside of the lower flange.

[0020] like Figure 1 , Figure 2 As shown, the bolt fasteners 5 are distributed at the four corners of the lower bracket 31 and the upper bracket 41 at their respective ends, and are used to tighten and fix the four corners of the lower bracket 31 and the upper bracket 41, thereby connecting the transverse fixing frame 3 and the longitudinal fixing frame 4, and connecting the transverse steel 1 and the longitudinal steel 2.

[0021] like Figure 1 , Figure 2 As shown, the upper end of the upper support 41 is bent and fitted with a clamping plate 42 that clamps and presses against the upper surface of the upper wing plate. The inner sides of the pair of clamping plates 42 abut against each other and wrap around the upper wing plate. Each clamping plate 42 is vertically fitted with a semi-circular insert plate 43. When the pair of upper supports 41 are interlocked, the pair of insert plates 43 are also interlocked and are tubular, allowing the end of the cantilever scaffold to be inserted.

[0022] like Figure 1 , Figure 2 As shown, a hook 44 is provided on one side of the insert plate 43, and a retaining ring 45 is provided on the other side for the hook 44 to pass through. Therefore, when a pair of insert plates 43 are fastened together, the hook 44 passes through the retaining ring 45 and achieves a second locking between the pair of insert rods, increasing the stability and tightness of the insert rods during operation.

[0023] like Figure 1 , Figure 3 As shown, a pair of sliding sleeves 6 are fitted on the longitudinal steel section 2. A positioning tube 61 is vertically installed on the sliding sleeve 6. The positioning tube 61 is inserted into the end of the cantilever scaffold to realize the limiting and fixing of the cantilever scaffold in multiple positions, and to realize the support of the cantilever scaffold, thereby increasing the stability of the connection position.

[0024] like Figure 1 , Figure 3 As shown, the sliding sleeve 6 includes a sleeve 62 and a side plate 63. The sleeve 62 is slidably sleeved on the upper wing plate of the longitudinal steel 2, and the side plate 63 is disposed on both sides of the sleeve 62 and clamps both sides of the web of the longitudinal steel 2 to achieve a snap-fit ​​fixation with the longitudinal steel 2.

[0025] Therefore, by setting up transverse fixing frames 3 and longitudinal fixing frames 4 to tighten the transverse steel 1 and longitudinal steel 2, and using bolt fasteners 5 to connect and fix the transverse fixing frames 3 and longitudinal fixing frames 4, the connection between the steel and the cantilever scaffold can be realized. This avoids the need for drilling holes in the steel for anchoring and achieves non-destructive anchoring. It also accurately positions the reasonable anchoring position of the cantilever scaffold, improves the safety and stability of the anchoring end position of the cantilever scaffold and the steel, and is highly practical.

[0026] like Figure 4 As shown, each lower support 31 has an amplitude processor 32 installed on its outer side wall. A pair of amplitude processors 32 are symmetrically distributed and located in the same cross-section, perpendicular to the neutral axis of the transverse steel 1. Each amplitude processor 32 is equipped with an amplitude sensor alarm 33 and an amplitude data display screen 34 on its side. The amplitude sensor alarm 33 is used to sound an alarm when the amplitude exceeds a preset value, and the amplitude data display screen 34 is used to display amplitude fluctuation data and record the maximum value.

[0027] like Figure 4As shown, a dual-axis vibration pickup 35 is provided on the side wall of the amplitude processor 32. The dual-axis vibration pickup 35 can monitor the horizontal and vertical vibration amplitude of the cantilever scaffold and feed back the monitored vibration amplitude to the amplitude processor 32. The amplitude processor 32 processes the data and determines whether the specified amplitude has been reached. If it has been exceeded, the amplitude sensing alarm 33 will sound an alarm.

[0028] like Figure 4 As shown, two sets of transverse strain gauges 36 are installed at the lower end face of the transverse steel section 1. The two sets of transverse strain gauges 36 are distributed in pairs, are located in the same cross section, and are parallel to the neutral axis of the transverse steel section 1. A strain processor 37 is installed below each amplitude processor 32. A strain sensing alarm 38 and a strain data display screen 39 are installed beside the strain processor 37. The strain sensing alarm 38 is used to sound an alarm when the value is exceeded, and the strain data display screen 39 is used to display the strain data and record the maximum value.

[0029] like Figure 4 As shown, the transverse strain gauge 36 can monitor the strain of the bottom steel of the cantilever scaffold and transmit the strain value to the strain processor 37 for processing to determine whether the allowable strain value is exceeded. If it is exceeded, the strain sensing alarm 38 will sound an alarm.

[0030] like Figure 4 As shown, a waterproof junction box 7 is provided on the outer side wall of the lower support 31. The waterproof junction box 7 is distributed on both sides of the amplitude processor 32 and extends to the lower end face of the transverse steel 1.

[0031] like Figure 4 As shown, all waterproof junction boxes 7 can prevent water from splashing in, ensuring that the amplitude sensor alarm 33, strain sensor alarm 38 and transverse strain gauge 36 can operate normally in rain and in severe weather.

[0032] Therefore, by adding devices to the transverse fixing frame 3 and the longitudinal fixing frame 4 that can monitor the horizontal and vertical amplitude and strain of the cantilever scaffold in real time, it is possible to provide early warning of the overturning of the cantilever scaffold and improve the safety and stability of the cantilever scaffold in the suspended state.

[0033] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
