Description

Technical Field

[0001] The utility model relates to the technical field of scaffold connection, in particular to a scaffold connection structure. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. According to the location of the scaffolding, it can be divided into external scaffolding and internal scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; according to the structural form, it can be divided into vertical pole scaffolding, bridge scaffolding, door scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.

[0003] An important aspect of urban renewal is the renewal of building facades, and the most common method of construction is the use of scaffolding. However, due to the complex site environment of the renewed building, there are often high and low spans, horizontal slopes, and vertical slopes. Therefore, during the scaffolding process, more cases require the use of temporary reinforcement with a brace.

[0004] When constructing high-rise buildings, bridges, tunnels and other projects, in order to increase the stability of the structure, it is often necessary to use a brace to support and fix the structure. Chinese patent CN201921029994.4 discloses an adjustable scaffolding base, which has the disadvantages of simple structure, insufficient support stability, height adjustment relying on a spiral rod, the brace adjustment angle cannot be fixed, and it is easy to become unstable when supported on an inclined surface. The inclination of the brace needs to be maintained between 45° and 60° during the construction process. When the inclination of the brace is not within the above range, it not only affects the completion acceptance of the scaffolding construction, but also affects the stability of the scaffolding construction. The brace is usually manually constructed to adjust the inclination of the brace during the construction process, and the manual construction process has uncertain factors, so that the brace needs to be manually constructed for a long time to calibrate the angle of the brace, which not only affects the progress of the scaffolding construction, but also when the angle of the brace is not up to the standard, the scaffolding will have safety hazards and cannot ensure the safety of workers using the scaffolding.

Example 2

[0043] refer to Figures 1 to 7 The steps of using the utility model are as follows:

[0044] P1: First install the positioning frame 3 through the installation component 8;

[0045] P2: Insert the bottom of the tossing support 1 into the interior of the tossing support fixing sleeve 2, and insert the limiting strip 16 on the surface of the tossing support 1 into the limiting groove 15 to align the tossing support 1, and then position the tossing support 1 in the interior of the tossing support fixing sleeve 2 through the positioning assembly 9;

[0046] P3: Then, pull out the positioning pin 13 from the positioning hole 12 to separate the positioning pin 13 from the positioning hole 12, and then rotate the castor support fixing sleeve 2 through the castor support 1, so that the castor support fixing sleeve 2 drives the movable rod 4 inside the positioning frame 3 to rotate, so that the screw 142 can drive the connecting plate 7 to rotate after the rotation, so that the connecting plate 7 can drive the movable disk 6 to move inside the angle limiting arc groove 5 after the rotation, and when the inclination angle of the castor support 1 is required to be 45 degrees, align the axis of the movable disk 6 with the axis of the forty-five degree hole 10, and then insert the positioning pin 13 into the forty-five degree hole 10 through the connecting plate 7 and the movable disk 6, when the inclination angle of the castor support 1 is required to be 60 degrees, align the axis of the movable disk 6 with the axis of the sixty degree hole 11, and then insert the positioning pin 13 into the sixty degree hole 11 through the connecting plate 7 and the movable disk 6;

[0047] P4: After the positioning pin 13 is inserted into the 45 degree hole 10 or the 60 degree hole 11, the positioning pin 13 is pushed inward and rotated. After the positioning pin 13 rotates inward, the positioning pin 13 can be installed on the bottom of the castor fixing sleeve 2 through the threaded mounting assembly 14, thereby completing the positioning of the castor at 145 degrees or 60 degrees.

[0048] The working principle and use process of the utility model are as follows: when in use, the fixing plate 82 is installed on the mounting track plate 81 through the bolts 83 on the fixing plate 82, so that the fixing plate 82 installs the positioning frame 3 on the mounting track plate 81, and then the tossing support 1 is inserted into the interior of the tossing support fixing sleeve 2, and the limiting strip 16 is inserted into the interior of the limiting groove 15, so that the opening of the through hole 93 of the tossing support 1 corresponds to the opening of the screw sleeve 91, and then the threaded installation rod 92 is inserted into the interior of the tossing support fixing sleeve 2, so that the left end of the threaded installation rod 92 is screwed into the interior of the screw sleeve 91 through the through hole 93, so that the threaded installation rod 92 inside the through hole 93 cooperates with the screw sleeve 91 to position and install the tossing support 1, and then the positioning pin 13 is pulled out from the inside of the positioning hole 12, so that the positioning pin 13 is separated from the positioning frame 3, and then the tossing support 1 is rotated, so that the tossing support 1 drives the tossing support fixing sleeve 2 to rotate, so that the tossing support fixing sleeve 2 passes through the movable rod 4 drives the connecting plate 7 to rotate, so that the connecting plate 7 rotates and drives the movable disk 6 to move inside the angle limiting arc groove 5. When the movable disk 6 moves inside the angle limiting arc groove 5 and the axis center is opposite to the axis center of the 45-degree hole 10, the positioning pin 13 is inserted into the positioning hole 12 through the connecting plate 7 and the movable disk 6, so that the castor 1 is inclined at 45 degrees. When the movable disk 6 moves inside the angle limiting arc groove 5 and the axis center is opposite to the axis center of the 60-degree hole 11, the positioning pin 13 is inserted into the positioning hole 12 through the connecting plate 7 and the movable disk 6, so that the castor 1 is inclined at 60 degrees. Subsequently, the interior of the positioning hole 12 is rotated so that the threaded groove 143 can be screwed on the surfaces of the screws 142 on both sides of the fixing block 141, so as to position the positioning pin 13 and ensure the stability of the positioning pin 13 when in use, thereby facilitating the positioning of the inclination angle of the castor 1 and achieving the positioning effect.

[0049] In summary, the scaffolding connection structure and the method of using the same, by setting the 45-degree hole 10 and the 60-degree hole 11, enable the brace 1 to be quickly positioned at an inclination of 45 degrees and 60 degrees, thereby solving the problem that the inclination of the brace is usually adjusted manually during the construction process. The manual construction process has uncertain factors, which requires a long time to calibrate the angle of the brace during construction, which not only affects the progress of the scaffolding construction, but also when the angle of the brace during construction does not meet the standard, the scaffolding will have safety hazards and cannot ensure the safety of workers when using the scaffolding.
