Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and specifically to a sector-shaped foldable protective net framework for buildings. Background Art

[0002] During building construction, there are many granular or small-sized building materials such as cement, sand, nails, nuts, etc. at the construction site, which are likely to scatter during construction. Therefore, on the one hand, to protect the environment, and on the other hand, to protect the safety of on-site construction workers, in existing building construction, a dust-proof dense mesh is mostly used to avoid the above safety hazards. When laying the dust-proof dense mesh, generally, a framework composed of vertical bars and horizontal bars needs to be erected first, and then the dust-proof dense mesh is fixed by means of knots and the like. This laying method is cumbersome, and as the construction progress advances, the laying work of the above dust-proof dense mesh also needs to be repeated, which not only wastes manpower and material resources, but also is not conducive to the promotion of future intelligent construction. Therefore, a foldable framework for protection can better make up for the above deficiencies. To make the foldable framework adapt to different building shape characteristics and achieve the functions of rapid storage and installation, a sector-shaped foldable protective net framework for buildings is designed.

[0003] According to the comparative document (patent name: A building protection frame, authorization announcement number: CN104975724A, application number: 201510355596.1), the device has good protection effect, but its structure is relatively complex, the installation process is cumbersome, it requires a lot of time and man-hours, and it occupies a large area and is not convenient for storage. Summary of the Invention

[0007] Preferably, a square groove one is opened at the center of the slidable connector one. The square groove one is adapted to support rod one. The slidable connector one can axially slide outside support rod one with support rod one as the axis through the square groove one. The upper and lower ends of the slidable connector one are in an arc-shaped structure, and two fixing holes one are opened at both the upper and lower ends.

[0034] The fan-shaped folding protective net framework for buildings adopts a modular design. When in use, the foldable framework is unfolded and the dust-proof dense net is fixed. When folding is required, the folding frame 1 can slide through the sliding connector 102 that can axially slide on the support rod 1 and the sliding connector 207 that can axially slide on the support rod 206, so that the connecting rod 205 moves in the square groove 2041 of the connecting rod 104, the support rod 101 and the support rod 206 approach each other, and the connecting rod 205 and the connecting rod 104 are in the same plane to complete folding. The folding column 1 and the folding column 2 can be folded through the hinge embedded in the centers of the folding column 1 and the folding column 2, completing the folding of the folding column 1 and the folding column 2. This can avoid the repeated laying of protective facilities. At the same time, the opening angle of the folding frame can be adjusted to adapt to different building shapes. The folding effect is good, the use is simple, it can be quickly folded and stored and opened for use following the progress of the construction. After folding, it occupies a small space and is easy to store and carry. After opening, it has stable force and is convenient to use. At the construction site, it can be lifted simultaneously with other protective devices, improving the construction efficiency and avoiding the problem that the repeated laying work of the dust-proof dense net needs to be repeated as the construction progress advances.
