Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a protective net for building engineering. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Safety nets are widely used in construction engineering. As a protective structure for separating construction areas, safety nets are installed on the perimeter of the construction area. By isolating the area with safety nets, external personnel can be prevented from entering, thereby ensuring the safety of construction operations.

[0003] In terms of structure, existing protective nets mostly adopt a prefabricated mesh panel structure. During installation, the protective net is laid out and installed by docking and assembling. Although the installation is convenient, the main structure of the prefabricated protective net is a rigid plate base, which is not only very inconvenient for transportation and storage, but also very inconvenient for turning during installation in non-linear areas. Therefore, a protective net for construction engineering is proposed. Utility Model Content

[0032] Working principle or structural principle: During installation, the layout of the protective netting is planned according to the characteristics of the construction area. First, the reference support piles 2 are installed at key nodes in the installation area by bolting. Then, the vertical reinforcing bars 4 in the middle of the mesh protective netting 1 are snapped into the slots at the ends of the limiting buckles 6 through slotted fasteners. During installation, ensure that the horizontal connecting bars 5 are engaged with the notches in the middle of the limiting buckles 6. Then, tighten the fastening nuts 7 to lock the vertical reinforcing bars 4 in place. During installation, the support piles 2 can be flexibly arranged and installed according to the site conditions. Similarly, the limiting installation of the key nodes in the middle of the mesh protective netting 1 and the support piles 2 is completed in sequence, thus completing the installation of the protective netting. Installation process In the process, for the long straight section of the protective net, before installation, a set of reinforcing beams 3 are first installed at the lower part of the supporting piles 2 using the connecting sleeve 10. Then, the vertical reinforcing column 4 end of the mesh protective net 1 is aligned and inserted with the reinforcing column insertion hole 9 in the middle of the reinforcing beam 3 through the slot positioning. Similarly, the connection and installation of the upper reinforcing beam 3 are completed. Then, the installed mesh protective net 1 is locked and limited by the limiting buckle 6, and the vertical reinforcing column 4 after insertion is locked and limited by the bolts. The installation of the long straight section of the mesh protective net 1 is completed. After use, the mesh protective net 1 is separated and disassembled. The mesh protective net 1 is rolled up and stored as a whole to reduce its storage volume, which can effectively facilitate the transportation and storage of the protective net.

[0033] In summary, this protective netting adopts a semi-rigid mesh netting 1, which is constructed by interlacing vertical reinforcing columns 4 and horizontal connecting ribs 5. It combines vertical rigidity with flexibility, allowing for flexible installation and layout according to the shape of the construction area. After use, it can be rolled up for easy transport and storage. The mesh netting 1 uses a split-pillar installation structure with fasteners, utilizing the vertical support of the split-pillar support columns 2 in conjunction with the limiting fasteners 6 and vertical... The interlocking of the reinforcing columns 4 provides support for the mesh netting 1. The structure is simple and easy to assemble and disassemble. During installation, the supporting columns 2 can be flexibly arranged and installed according to the site conditions, which greatly improves the convenience of installation and operation and the flexibility of use of the netting. The reinforcing beams 3 are split and are connected to the vertical reinforcing columns 4 of the mesh netting 1 through the hole insertion. The assembly and disassembly are convenient. When laying out long straight sections of netting, the addition of reinforcing beams 3 can effectively improve the support stability of the netting.
