[0002] Housing construction refers to a project with a roof, beams, walls, foundations and the ability to form an internal space to meet people's needs for production, residence, study, public activities, etc. Housing construction projects are generally referred to as construction projects, which refer to the various technical work such as survey, planning, design, construction, installation and maintenance for the construction, reconstruction or expansion of housing buildings and ancillary structures, as well as the completed engineering entities. When building a house, guardrails are often required to isolate the construction site from the external environment. At present, most of the guardrails used in housing construction are spliced ​​with multiple small guardrails to protect the construction site of the house building. However, the splicing of existing small guardrails is mostly connected by bolts and nuts, and the splicing is relatively cumbersome and very inconvenient during subsequent disassembly. Therefore, we propose a guardrail for housing construction. Utility Model Content
