Description

Technical Field

[0001] The utility model relates to the field of scaffolding, in particular to a triangular cantilever rod of a disc-lock scaffolding. Background Art

[0002] At present, the scaffolding in the construction process cannot be well placed and connected in some construction areas. Although the connection method of the bolt and the connection fastener is convenient for the transportation and connection of the bracket, in some special environments where the scaffolding must be suspended, the connection of the scaffolding cannot be placed flat and effectively, which leads to a decrease in the stability and safety of the bracket. In addition, due to the possibility of errors in the manual connection method using the bolt, the connection is not standardized. It is now urgent to design a cantilever rod to facilitate better operation by construction workers and more stable connection of the scaffolding. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a triangular cantilever rod of a scaffolding with a buckle, so as to optimize the buckle pins of the scaffolding, realize multi-angle pin fixation of the scaffolding, and reduce the situation of improper installation of the scaffolding caused by human operation.

[0004] In order to achieve the above-mentioned purpose, a triangular cantilever rod of a disk-lock scaffolding is designed, comprising a disk-locked disk, a vertical rod arranged in the middle of the disk-locked disk and a horizontal rod connected to the vertical rod at one end, the disk-locked disk is provided with a plurality of through holes along the circumferential direction, and an arc-shaped through groove is provided between two adjacent through holes; a latch is provided at the other end of the horizontal rod, and the latch comprises a long latch arranged in the middle and short latches located on both sides of the long latch, the arrangement of the long latch and the short latch is matched with the curvature of the arc-shaped through groove, and the spacing between the long latch and the short latch is matched with the distance between the through hole and the arc-shaped through groove.

[0005] Preferably, the buckle-type disc of the utility model is provided with four equally distributed through holes along the circumferential direction, and the arc-shaped through grooves and the through holes are staggered.

[0006] Preferably, the latch at the other end of the cross bar of the utility model is used to connect to the through hole or through groove of another buckle-type disc.

[0007] Preferably, the long pin of the cross bar pin of the utility model is used to connect the through hole or the through slot. When the long pin is connected to the through hole of another disc-type disc, the short pin is respectively connected to the through slots on both sides of the through hole. When the long pin is connected to the through slot of another disc-type disc, the short pin is simultaneously connected to the same through slot.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] 1. The design of the triangular cantilevered rod of the disc-lock scaffolding can effectively improve the safety of aerial work. The working platform is set up on the cantilevered components, which avoids the workers working in the air. While improving the construction efficiency of the construction personnel, it also ensures the safety of the construction.

[0010] 2. Even if it is not used as a working platform, it can be set up as a binding point for construction workers' safety belts to ensure the safety of the workers.

[0011] 3. The triangular cantilever rod design of the disc buckle scaffolding also reduces the difficulty of setting up some scaffolding to a certain extent, so that the place where the working platform needs to be set up does not need to set up the working support from the ground. It prevents the adjustable bottom support of the working scaffolding and the supporting scaffolding from being placed and set in an irregular manner due to space reasons.

[0018] In order to make the purpose, principle and structure of the utility model clearer, it is further described below in conjunction with the drawings and specific embodiments.

[0019] Embodiment 1:

[0020] The present embodiment provides a triangular cantilever rod of a disc-lock scaffold, comprising: a disc-lock 1, a vertical rod 2, a horizontal rod 3, a latch 4 and a cantilever operating platform 5.

[0021] The disc 1 has a diameter of 130 mm, and has 4 symmetrical through holes 1.1 and 4 symmetrical through slots 1.2 evenly distributed thereon. The through holes 1.1 have a width of 22 mm and are 6 mm from the edge of the disc (see Figure 2 ).

[0022] The latch 4 adopts a three-pronged latch (see Figure 1 ), so that the long pin 4.1 can be inserted into the disc through hole 1.1, and the short pins 4.2 at both ends can lock the crossbar, so that the connection between the pin 4, the disc buckle 1, the crossbar 2 and the vertical pole 3 is more stable, avoiding the unstable connection of the scaffolding caused by the mistakes of the construction workers. The width of the bottom plate of the pin 4 is 44mm, the thickness of the middle long pin 4.1 is 3mm, the length is 52mm, and the thickness of the short pins 4.2 at both ends is 2mm, and the length is 31mm. The clear span between the short pins 4.2 at both ends and the middle long pin 4.1 is 22mm.

[0023] Specific installation steps:

[0024] Prefabricate cantilever rods of various sizes in the factory to facilitate on-site construction needs. The crossbar angle can be prefabricated to 90 degrees (see Figure 3 ), the cross bar length can be in four sizes: 0.3m, 0.6m, 0.9m, and 1.2m (the length size is determined based on the actual situation on site).

[0025] The prefabricated disc-type scaffolding cantilever rods and other components such as vertical poles 2 and cross bars 3 of required sizes are transported to the site. Lay out the lines on site to confirm the reference point of the erection, place the adjustable base at the reference point, and adjust the adjustable base nut to approximately the same height according to the size. Then install the starting pole vertical pole 2, and insert the starting pole vertical pole 2 into the adjustable base. Then connect the sweeping pole cross bar 3 and the disc 1 on the starting pole vertical pole 2 through the pin 4, and the height of the sweeping pole cross bar 3 from the ground shall not be higher than 550mm. Then install the vertical poles and cross bars, and use socket-type connections between the vertical pole 2 and the starting pole vertical pole 2, and between the vertical poles 2 and the vertical poles 2 to form a rigid connection, the vertical pole 2 and the cross bar 3. After the foundation frame is erected, the cantilever bar crossbar is connected to the adjacent vertical bar disc 1 that has been erected through the special pin 4. The middle long pin 4.1 of the special pin 4 is normally inserted into the crossbar 3 hole and the through hole 1.1 of the buckle disc to form a connection. The other two short pins 4.2 are fixed on both sides of the cantilever crossbar 3 and inserted into the through groove 1.2 of the buckle disc to play a common fixing and limiting role. Each span should be connected to the cantilever bar, and this process is repeated to continuously build a cantilever platform with enough pedals (see Figure 4 ). Then, the prefabricated pedal with a certain angle is installed on the cantilever rod to build a cantilever work platform 5 (see Figure 5 The prefabricated steel pipe central short vertical pole can still be connected to the vertical pole by the socket method, and can also be made into a non-cantilevered rod.

[0026] Embodiment 2:

[0027] In the assembly method of the first embodiment, the long pin 4.1 of the pin 4 can also be inserted into the through slot 1.2, and the short pins 4.2 on both sides are also inserted into the through slot 1.2 to achieve the fixation of the buckle 1, the cross bar 2, and the vertical bar 3.

[0028] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
