Description

A Combined Scaffolding Passage for People

technical field

The utility model relates to a walking passage, in particular to a combined scaffolding walking passage, which is applied to temporary walking passages of outer eaves scaffolding of construction projects and deep foundation pit underground engineering scaffolding projects.

technical background

Scaffolding refers to the various supports set up on the construction site for workers to operate and solve vertical and horizontal transportation. A general term in the construction industry, which refers to the construction site used for exterior walls, interior decoration, or places with high floor heights that cannot be directly constructed. It is a component for construction workers to work up and down, or for peripheral safety net maintenance and high-altitude installation. In order to enable construction workers to work on the scaffolding platform and to facilitate the transportation and storage of construction materials, it is necessary to set up a passage on the scaffolding platform. Scaffold access is an increasingly urgent problem to be solved in building exterior eaves and deep foundation pit underground engineering.

In recent years, the research and development work done by engineering technicians in the construction industry on the scaffolding access has been disclosed by the following patent documents:

1. Chinese utility model patent, authorized announcement number CN203755717U, authorized announcement date August 06, 2014 "Deep foundation pit assembled upper and lower pedestrian passageway" discloses a deep foundation pit assembled upper and lower pedestrian passageway, including: respectively composed of four The square column is erected according to the four apex positions of the rectangle to form a left fixed frame and a right fixed frame. The stair platforms are staggered in height, one side of the stair platform is connected to the upper stair platform on the opposite side of the fixed frame through an inclined stair step plate, and the other side of the stair platform is connected to the lower stair platform through an inclined arrangement. The stair step boards are connected.

Its beneficial effect: the pedestrian walkway in the middle adopts a prefabricated structure, and the square column constitutes two relative fixed frames on the left and right, which is convenient for assembling the stair step board between the two opposite fixed frames. The disassembly process is simple, saves labor and trouble, and can be disassembled repeatedly The equipment can be reused, and the material waste is small, which enhances the practicability, safety, aesthetics and material reusability of the upper and lower pedestrian passages.

Its shortcomings:

1) Only for deep foundation pit engineering, the scope involved is narrow, and it is not suitable for scaffolding projects on the ground and outer eaves; 2) The left and right fixing frames, stair platform and stair step board still need to be assembled on site, which is time-consuming;

3) The steel wire mesh is only installed on the stair platform, which does not cover all the parts and has a low safety factor;

4) The entrance and exit settings are not fixed, which cannot achieve standardization, which is not conducive to recycling.

The stairs are set on the frame and surrounded by the outer protective net.

The stairs are parallel double-running stairs and are composed of stair steps, stair landings and stair guardrails. The stair steps, stair landings and stair guardrails are all made of 2.5mm thick patterned steel plates, wherein the stair steps are in the middle, and the stair landings are Located on the left and right sides, the stair guardrail is made of a steel pipe with a diameter of 50mm and is located on the side of the stair steps.

As mentioned above, the fence door between floors is a movable fence door made of steel pipe with a diameter of 50mm, which is used as a passage for entering and leaving the building, with a width of 1000mm and a height of 2000mm.

According to the depth of the foundation pit and the height of the floor, multiple groups of access passages can be set for the access passage of the combined scaffolding, and every two access passages of the combined scaffolding are connected together through bolt holes with high-strength bolts.

Advantages of the utility model

Compared with the prior art, the utility model has the following

1) A single piece is a standard piece, which can be combined up and down according to the height of the building, and can be placed interchangeably on the left and right, so as to change the direction of the entrance and exit;

2) Easy installation and disassembly, simple and fast operation, saving construction period;

3) The safety net is fully covered and the safety factor is high;

4) The components are strong, not easy to damage, low maintenance cost, recyclable, and meet the construction standards of green civilization.
