Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a springboard for scaffolds. 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. The springboard in the scaffolding is the main platform for carrying workers and objects.

[0003] The installation of the springboard needs to be carried out after the single-layer overall frame of the scaffolding is completed. During the installation process, it needs to be placed inside the frame at the lower corner. In order to ensure the structural strength of the scaffolding, the springboard is often made of metal, so the weight of the springboard is heavy. The process of placing the springboard requires multiple adjustments in posture, and the gussets at both ends of the springboard are buckled to the crossbars of the frame. The operation is cumbersome, time-consuming and labor-intensive, and the gussets may be deformed or broken during transportation or long-term use. The damage to the gusset structure requires welding repair, or the entire springboard is scrapped. The springboard is difficult to repair and has high replacement costs. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1 and Figure 2 In the utility model, a springboard for scaffolding includes a frame 1, a steel mesh 2 is fixedly installed on the top of the frame 1, two movable grooves 3 are provided on the left and right sides of the frame 1, a buckle 4 is rotatably connected inside the movable groove 3, and a reset spring 5 is fixedly installed at the rotation connection between the buckle 4 and the movable groove 3.

[0025] The frame 1 includes a steel frame 11, and fixing rods 12 are installed on both sides of the steel frame 11. A mounting rod 13 is integrally formed on the side of the fixing rod 12 away from the steel frame 11. The movable groove 3 is opened on the mounting rod 13. The steel frame 11 and the fixing rod 12 are both provided with mounting holes 14. Bolts are inserted into the inner sides of the corresponding mounting holes 14 on the steel frame 11 and the fixing rod 12, and are fixed by bolts.

[0026] In the utility model, since the buckle ring 4 is hinged to the inner side of the movable groove 3, during the process of placing the springboard, the springboard is lifted up. When the buckle rings 4 on both sides hit the crossbar of the scaffolding, they are forced to fold downward, thereby reducing the width of the entire springboard, allowing the springboard to easily pass through the left and right crossbars, and then move the springboard to above the two crossbars. After the buckle ring 4 loses the restriction of the crossbar, the elastic force of the reset spring 5 drives the buckle ring 4 to reset, and then it can be carried on the crossbar to complete the installation of the springboard. In the narrow space of the scaffolding frame, the difficulty of assembling the springboard is reduced, the efficiency of placing the springboard is improved, and it is more time-saving and labor-saving.

[0027] Since the springboard serves as the direct bearing surface for personnel and objects, the connection points between the buckle rings 4 at both ends of the springboard and the skeleton crossbars are the main stress points. Factors such as transportation and long-term use may cause the buckle rings 4 to deform or break. By removing the bolts, the fixing rods 12 and the installation rods 13 on both sides of the steel frame 11 can be removed, so that the buckle rings 4 can be replaced, reducing the maintenance difficulty and replacement cost of the springboard.

[0028] The cross-section of the fixing rod 12 is C-shaped, and the left and right edges of the steel frame 11 are wrapped inside the fixing rod 12 .

[0029] In the utility model, the C-shaped fixing rod 12 can wrap the side of the steel frame 11. After the bolts are installed, the contact surface between the fixing rod 12 and the steel frame 11 is larger, thereby dispersing the stress points and improving the stability and reliability of the installation of the fixing rod 12 and the steel frame 11.

[0030] Among them: the elastic force of the return spring 5 is slightly greater than the gravity of the buckle 4.

[0031] In the utility model, the elastic force of the reset spring 5 is only provided to overcome the gravity of the buckle 4 to complete the reset work, avoiding excessive elastic force, which causes the buckle 4 to be folded downward after being resisted, so that construction workers can save more effort when assembling the springboard.

[0032] Wherein: the top of the buckle ring 4 in the initial state contacts the inner top wall of the movable groove 3.

[0033] In the utility model, the inner top wall of the movable groove 3 can limit the upward turning of the buckle 4, thereby ensuring the stability of the structure after the buckle 4 is mounted on the cross bar.

[0034] Wherein: a fixing pin 6 is inserted into the installation rod 13 , and the bottom end of the fixing pin 6 extends to the inside of the movable groove 3 and is inserted into the buckle 4 .

[0035] In the utility model, the fixing pin 6 is plugged into the buckle ring 4, and after the springboard is assembled, the buckle ring 4 is locked to fix the structure of the buckle ring 4 and improve the stability of the buckle ring 4.

[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
