Description

Technical Field

[0001] The utility model relates to the technical field of construction enclosures, in particular to a construction enclosure structure which can effectively reduce occupied space. Background Art

[0002] During the construction of engineering projects, especially municipal engineering projects, it is crucial to maintain the safety of the construction area and prevent surrounding residents and pedestrians from mistakenly entering the construction area. To achieve this goal, special fences are usually set up around the construction area. These fences not only play a role in isolation, but also are an important measure to ensure construction safety. These fences are usually composed of multiple independent guard plate units connected together, designed to facilitate transportation and on-site assembly. At the same time, through this combination, when a single plate unit is damaged, it can be quickly replaced, greatly improving the maintainability and economic benefits of the enclosure system.

[0003] The patent with the publication number CN218522445U discloses an assembled construction enclosure structure, including a base, a first fixing screw is arranged on the top of the base, a first column and a second column are arranged on the top of the base, a pressure strip is arranged on the first column and the second column, a second fixing screw is arranged on the pressure strip, an enclosure is arranged on the side of the pressure strip, a hole is opened on the enclosure, a card slot is opened on the side of the first column, a limited position opening is arranged in the card slot, a clamp is arranged on the second column, and rubber columns are arranged on both sides of the clamp. The utility model is provided with a member including an enclosure, a pressure strip, a first column and a second column. When the enclosure is damaged after being used for a period of time, only the corresponding enclosure plate needs to be replaced to make the enclosure continue to be used, thereby increasing the service life of the enclosure. At the same time, the fixing method of the pressure strip makes it more convenient and quick to replace the enclosure, thereby increasing the speed of erecting the enclosure.

[0004] Although the above-mentioned prior art improves the maintainability and safety of the hoarding, it still faces certain limitations, especially when the length of the hoarding is fixed. This makes it impossible to flexibly adjust the enclosed ground space, especially in the city center or in a construction environment with limited space, the hoarding may occupy too much space. In view of this, we propose a construction hoarding structure that effectively reduces the occupied space. Utility Model Content
