Description

Double-sided pedal

Technical Field

The invention relates to the field of composition or accessories of scaffolds, in particular to a double-sided pedal.

Background

The scaffold is used as an auxiliary facility in the building construction process, and ensures that the construction process is smoothly carried out and the working platform is erected. The scaffold is also used for the construction of large ships in shipbuilding factories, but the difference is that the large ships are constructed in a modularized mode, and all modules forming the ships are independently constructed firstly and then are combined and spliced. The scaffold is erected by taking each module as a working object. In addition, the module is subjected to a plurality of processes such as welding, sand blasting, paint spraying and the like during the construction process, the process sites also include outdoor and indoor closed sites, and the module is required to be turned over during the construction process so as to perform operations on various parts.

The pedal is a part of the scaffold and is used for workers to walk and stand. In the prior art, the pedal is often a door-shaped structure formed by bending a plate, a plurality of small holes are formed in the top surface, one surface of the pedal is downward, only the top surface can be stepped, and one side of the pedal cannot be stepped by a person. During module construction, scaffold and module fixed connection, therefore scaffold will overturn along with the module upset, and footboard after the upset then can't supply to apply workman's walking, stand, and it is fixed to overturn after needing to demolish, and the work load of dismouting footboard is very big, and construction latency is very long, seriously influences the efficiency of construction of naval vessel.

Preferably, the cross section of the upper side panel and the lower side panel is of a door-shaped structure, the upper side panel and the lower side panel are butted in a mode that the openings are opposite, end side lines of the upper side panel and the lower side panel are both bent inwards to form curled edges, one curled edge of the upper side panel abuts against one folded corner of the lower side panel from the inside, the other curled edge of the upper side panel wraps the other folded corner of the lower side panel from the outside, and the lower side panel is symmetrically arranged in the same mode.

Preferably, the cross section of the folded angle and the curled edge is acute angle structure.

Preferably, the end plate is riveted to the upper or lower side panel.

Preferably, the pedal further comprises a pipe sleeve, wherein the pipe sleeve penetrates through the upper surface and the lower surface of the pedal body to tread the pedal face and is fixedly connected with the pedal body.

Preferably, the upper end port and the lower end port of the pipe sleeve are smooth.

Compared with the prior art, the invention has the beneficial effects that: the pedal body of the closed box-packed structure can be treaded on the upper surface and the lower surface, and can be used for workers to walk and stand, so that the scaffold can be directly used after being turned over along with the ship module, and the scaffold does not need to be installed and fixed after being dismantled, thereby shortening the construction waiting time and greatly improving the construction efficiency; in addition, the process requirements and construction site restrictions of ship module manufacturing are fully considered, the steel shot subjected to sand blasting cannot fall inside the pedal, and if the steel shot falls inside the pedal, the steel shot can fall out and smash the paint surface in the paint spraying process to damage the paint surface, so that the problems are completely avoided. The present invention generally meets the need for efficient ship building.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

As shown in fig. 1-3, a double-sided pedal comprises a pedal body 1, wherein the pedal body 1 is of a closed box-shaped structure, and the upper surface and the lower surface of the pedal body 1 are treading surfaces 2. Therefore, the pedal body 1 can be directly used after being turned over along with the scaffold, and does not need to be dismounted and then turned over for installation and fixation, so that the time waste caused by dismounting the pedal, turning over and installation and fixation is eliminated, and the module building efficiency is improved. In addition, because the pedal body 1 is of a closed box-packed structure, steel shots in the sand blasting process cannot be left in the pedal body 1, and residual water cannot be left in the pedal body 1 in open-air operation, so that the paint surface quality problem caused by the steel shots and the residual water is eliminated in the subsequent paint spraying process, and the paint surface quality is effectively ensured.

In this embodiment, the pedal body 1 includes an upper side panel 3, a lower side panel 4 and an end plate 5, the upper side panel 3 and the lower side panel 4 are butted up and down, the end plate 5 is disposed at both ends, and the upper side panel 3, the lower side panel 4 and the end plate 5 together form a closed box-like structure.

In the present embodiment, the cross section of the upper panel 3 and the lower panel 4 is a door-shaped structure, the upper panel 3 and the lower panel 4 are butted in a manner that the openings are opposite, the end edges of the upper panel 3 and the lower panel 4 are both bent inwards to form a turned edge 6, one turned edge 6 of the upper panel 3 abuts against one folded corner 7 of the lower panel 4 from the inside, the other turned edge 6 of the upper panel 3 wraps the other folded corner 7 of the lower panel 4 from the outside, and the lower panel 4 is symmetrically arranged in the same manner.

With such a structure, on the one hand, the structural strength of the pedal body 1 is improved due to the tension generated by the upper side panel 3 and the lower side panel 4 at the curled edges 6 and the folded corners 7, and even if the width of the pedal body 1 is relatively small, the middle part of the pedal body is not deformed; on the other hand, the joint of the upper side panel 3 and the lower side panel 4 has better sealing performance, and can effectively prevent water from flowing into the pedal body 1.

In the present embodiment, the cross-section of the folded angle 7 and the folded edge 6 are both acute angle structures. Thereby ensuring that the upper side panel 3 and the lower side panel 4 generate enough tension at the curled edges 6 and the folded corners 7, and ensuring that the pedal body 1 has enough structural strength; meanwhile, the cross sections of the folded angle 7 and the turned edge 6 are acute-angle structures, so that the sealing performance is stronger relative to a right-angle structure, and water is guaranteed not to flow into the pedal body 1.

In this embodiment, the end plate 5 is riveted with the upper side panel 3 or the lower side panel 4, the connection is reliable and firm, the use of screw connection is avoided, the time is long, the screw is easy to fall off, the screw falls off when spraying paint, the paint surface can be damaged, and therefore, the riveting fixation is used, and the quality of the paint surface is also ensured.

In this embodiment, the pedal device further comprises a pipe sleeve 8, and the pipe sleeve 8 penetrates through the upper and lower surfaces of the pedal body 1 and the treading surface 2 and is fixedly connected with the pedal body 1. The pipe sleeve 8 is used for penetrating through a rope for lifting the pedal body 1 to ascend and descend, the pipe sleeve 8 protects the lifting rope, the lifting rope is prevented from directly rubbing the pedal body 1 in the using process, and the lifting rope is easily abraded and cut off due to direct rubbing.

In this embodiment, the upper and lower end ports of the pipe sleeve 8 are smooth, further protecting the hoisting ropes.

In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
