Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a protective net structure for deep foundation pit supporting engineering of high-rise buildings. Background Art

[0002] The protective nets used in deep foundation pit support projects mainly include deep foundation pit protective nets. This type of net is mainly used for the safety protection of construction projects, and can provide sufficient defense for deep foundations, deep foundation pits and other projects. It is mainly used to isolate the construction site from the surrounding environment during foundation pit excavation, earthwork, building construction and other engineering operations to ensure that the construction site is safe and orderly. It can also effectively reduce the impact of noise and vibration on surrounding residents and play a role in protecting surrounding residents. During the use of the protective net, the protective net is set to a fixed size, so the scope of use of the protective net is limited. For some openings, using one protective net cannot protect them well, and using two protective nets will be larger than the width of the hole. In this way, the traditional protective net cannot be well applied to the protection of the hole, reducing the applicability of the equipment and affecting the scope of use of the equipment.

[0003] In order to solve the above problems, the utility model patent with publication number CN218912339U discloses a protective net for construction projects, which can be adjusted according to the size of the holes, thereby increasing the applicability of the equipment, avoiding the problem that traditional equipment cannot provide good protection when encountering special holes, improving the scope of use of the equipment, and increasing the effect and quality of the equipment during use.

[0004] During the use of the above-mentioned protective net, it is not convenient to shrink the protective net when not in use, which makes it inconvenient to pick up and carry the protective net during transportation due to its large size and large number, and it occupies more storage space during vehicle transportation. At the same time, when the protective net is stored, it also occupies more factory space, which reduces the retractability of the protective net. It is also inconvenient to adjust the protective width of the protective net according to needs, which reduces the adjustability of the protective net. When installing the protective net, it is usually necessary to screw multiple screws for installation, which makes the installation process more complicated and troublesome, requires a lot of manpower and time, and wastes human resources. At the same time, it is not convenient to disassemble the protective net, which increases the working time and disassembly cost when installing and disassembling the protective net, reduces work efficiency, and thus delays work progress.

A handle 25 is fixedly connected to the middle part of the left side of the gear 2 10 for shaking the gear 2 10 for rotation.

[0033] A mounting groove 11 is provided on the inner side of the mounting column 3 for facilitating the installation of a sliding rod 12. The right side of the right protective net 1 is fixedly connected with the sliding rod 12 for facilitating the installation of the protective net. A fixing plate 13 is fixedly connected to both upper and lower ends of the right side of the right protective net 1. A square groove 14 is provided on the inner side of the middle part of the fixing plate 13 for installing a card block 18. A mounting block 15 is slidably connected to the inner side of the square groove 14. Two springs 16 are fixedly connected to the front side of the mounting block 15 for increasing the elastic force of the card block 18 for facilitating the rebound of the card block 18 and improving the tightness of the engagement. Two connecting columns 17 are fixedly connected to the front side of the mounting block 15. A card block 18 is fixedly connected to the rear side of the mounting block 15 for engaging with the card groove 19.
