Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a construction engineering protection net. Background Art

[0002] During construction, in order to improve work safety and maintain environmental hygiene, protective nets are generally installed around buildings. Their main function is to prevent falling objects from high altitudes from causing harm to construction workers, while also curbing the spread of dust and reducing pollution to the surrounding environment.

[0003] However, although the current protection net system is usually composed of a fixed frame structure carrying the net surface, there are still several aspects of this design that need to be improved:

[0004] 1. The contradiction between structural rigidity and spatial adaptability: The current combination of the frame and mesh of the protective net is relatively fixed, and its size and shape are not easy to change flexibly. This fixedness leads to the inability of the protective net to make efficient spatial adaptability adjustments when facing areas of different sizes and shapes to be protected, and it occupies a large area of ​​the site, which is not conducive to achieving the best layout on a limited construction site.

[0005] 2. Lack of bottom protection: When installing the existing protection net system, the bottom of the frame usually needs to be supported and positioned with the help of a fixed seat. This structural feature inevitably forms a certain gap between the protection net surface and the ground. The existence of this gap not only weakens the overall airtightness of the protection net, making it difficult to effectively cover and protect the ground working area, but also provides a channel for potential safety hazards and dust escape. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide a construction engineering protection net to solve the technical problems faced by existing construction protection nets in actual applications, such as occupying too much space, being difficult to adapt to complex construction environments, and having poor bottom protection effects.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: a construction engineering protection net, comprising:

[0008] A first upright column, a first connecting portion being provided on a side thereof;

[0009] A second column has a winding space formed inside thereof, a winding shaft is rotatably connected in the winding space and a lead-out groove is formed through the side of the second column;

[0010] A flexible protective net, one end of which is fixed to the winding shaft, and the other end of the flexible protective net is wound on the winding shaft and at least partially passes through the lead-out groove;

[0011] A plurality of bottom protection nets are arranged closely in sequence at the bottom of the flexible protection net, and a side of the plurality of bottom protection nets away from the flexible protection net is folded upward along the connection position thereof and is detachably connected to the flexible protection net through a first flexible connection piece;

[0012] Wherein, the portion of the flexible protective net passing through the lead-out groove is provided with a second connecting portion, and the first connecting portion and the second connecting portion are detachably connected.

The flexible protective net can be wound on the winding shaft inside the second column and can be freely extended and retracted through the lead-out groove, which solves the problem of fixed size and poor spatial adaptability of traditional protective nets. In this way, the protective net can quickly adjust the coverage and shape according to the specific needs of the actual area to be protected, significantly reducing the floor space and improving the adaptability in complex construction environments. In addition, due to the addition of several bottom protective nets, which are detachably connected to the flexible protective net through the first flexible connector, the defect of the lack of bottom protection of the existing protective net is effectively compensated.

[0016] The utility model is further configured such that another first connecting portion opposite to the lead-out groove is provided on the other side of the second column away from the lead-out groove.

[0017] By adopting the above technical solution, the second column can be expanded through another first connecting part, so that it can continue to be connected to another second column, thereby further expanding the coverage of the flexible protective net.

[0018] The utility model is further configured such that the first connection portion is sheet-shaped and vertically distributed on the side wall of the first column, the first connection portion is provided with a plurality of connection holes spaced apart along its length direction, and the second connection portion is a plurality of hook portions corresponding one-to-one to the connection holes.

[0019] By adopting the above technical solution, the flexible connection net and the first column can be easily disassembled and connected through a plurality of connection holes and hook parts, making the overall practicality of the protective net more convenient and quick.

[0020] The utility model is further configured that the connecting hole is a strip-shaped waist hole, and the waist holes are vertically distributed, and the hook part is a sheet-shaped hook corresponding to the waist hole.

[0022] The utility model is further configured such that a hard side plate is fixed along an edge of one side of the flexible protective net passing through the lead-out groove, and a plurality of the hook parts are sequentially arranged on the hard side plate.

[0023] By adopting the above technical solution, the hard side plates are fixed on the edge of the flexible protective net, which helps to keep the net surface flat, prevent deformation, and improve the protective effect.

[0024] The utility model is further configured such that the sides of the bottom protective net are provided with flexible edge sealing, the first flexible connecting member includes a first fixing ring and a first flexible rope for connecting the first fixing ring and the flexible edge sealing, and each first flexible connecting member on the bottom protective net is provided with two and symmetrically distributed on both sides of its bottom edge.

[0025] By adopting the above technical solution, the two first flexible connectors symmetrically distributed on the bottom protective net and the connection method between the first flexible connector and the flexible edge sealing ensure that the bottom protective net remains balanced during stretching and contraction, avoiding deflection that affects the protective effect.

[0026] The utility model is further configured such that the flexible protective net passes through the side of the lead-out groove and is provided with a second flexible connector at its bottom, and the second flexible connector includes a second fixing ring and a second flexible rope for connecting the second fixing ring and the edge of the flexible protective net.

[0027] By adopting the above technical solution, the second flexible connecting member can further tighten and fix the bottom edge of the flexible protective net to the ground through the second flexible rope and the second fixing ring, further strengthening the fit between the bottom edge of the flexible protective net and the ground, preventing the net surface from sagging or lifting up, and enhancing the tightness of the bottom protection.

[0028] The utility model is further configured such that a pair of transition edges with arc-shaped cross sections are symmetrically provided on the inner side of the winding space located at the opening of the lead-out groove.

[0029] By adopting the above technical solution, the design of the transition edge smoothes the edge of the lead-out slot opening, reduces the friction resistance when the mesh surface enters and exits, and protects the flexible protective net from wear.
