technical field

The utility model relates to a border enclosure structure, in particular to a conversion base for a border enclosure and a multipurpose border enclosure.

Background technique

Usually, at construction sites such as foundation pits of industrial and civil buildings, main structures, or ditches of municipal engineering, enclosure railings should be set up on the sides of foundation pits with large height differences to prevent construction workers from falling from high places and causing casualties. At the construction site, the special steel bars pre-buried on the edge of the building are usually used as the fulcrum, and the fasteners and steel pipes are used to build protective railings, or to bind iron wires, moso bamboo or wooden poles to form protective railings. When steel pipes are combined with various fasteners, it is time-consuming and labor-intensive to set up, and the stability is poor, and the steel pipes protrude, hindering passage and subsequent construction operations. When using square tubes and round tubes for welding, it needs to be made to length according to the shape of different foundation pits or ditches, and the reuse rate is low.

In addition, after the construction of the foundation pit is completed, most of the perimeter fence railings, which are time-consuming and material-consuming, need to be removed from the site. In the subsequent structural construction stage, with the appearance of the perimeter opening and the elevator shaft opening, there is still Protective facilities such as safety doors for access elevators are required. It can be seen that for different enclosure objects, the perimeter enclosure and the elevator safety door protection need to enter the site once respectively, and the perimeter enclosure cannot be reused. At present, the construction cost of foundation pit perimeter protection is high, the benefit is low, and it cannot be reused, resulting in a serious waste of resources.

Under the requirements of green construction, the development of a multi-purpose and reusable temporary enclosure system is of great significance for reducing construction costs, shortening the construction period and improving the level of on-site management.
