Detachable open type invisible protective net

Abstract

The invention belongs to the field of construction and building materials, and discloses a detachable open type invisible protective net which comprises an upper frame rail, a lower frame rail and netpieces. The upper ends and the lower ends of the net pieces are connected with the upper frame rail and the lower frame rail; the upper frame rail comprises an upper main section strip, the upper main section strip comprises an upper connecting portion and an upper body, the upper connecting portion is used for fixing the upper main section strip, the upper body is used for being connected with ahang groove member, and the hang groove member is connected with the upper body by bolts; the lower frame rail comprises a lower main section strip, the lower main section strip comprises a lower connecting portion, a lower body, bearing grooves and a butting structure, and the butting structure is positioned above the bearing grooves; the net pieces comprise nets, upper clamp rods which are clamped with the hang groove member are arranged on the upper portions of the nets, and lower clamp rods which are clamped with the bearing grooves are arranged on the lower portions of the nets. The detachable open type invisible protective net has the advantages that the detachable open type invisible protective net can be quickly detached and recovered; personnel can access the detachable open typeinvisible protective net to carry out outdoor equipment mounting and maintaining, personnel escape and rescue and the like on the premise that the detachable open type invisible protective net is notdestroyed and use functions of the detachable open type invisible protective net are not deteriorated; the construction cost, the use cost and the maintenance cost of the detachable open type invisible protective net in late periods can be reduced.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a detachable and openable invisible protective net. Background technique [0002] With the development and progress of society, the design of buildings is more and more in line with people's aesthetics. In addition to achieving sufficient strength in structure, it is also necessary to maintain a unified design in appearance. For the sake of safety, people often set up protective windows or protective nets at the positions of windows to realize functions such as anti-theft and anti-falling. However, the protective windows of traditional stainless steel pipes or iron sash windows not only greatly reduce the appearance, but also seriously damage the facade effect of the building designed by the architect, which greatly reduces the grade of the building. In order to avoid this problem, people began to install invisible protective nets, which can not destroy th...

AI Technical Summary

Problems solved by technology

[0003] 1. In case of danger, the protective net blocks the windows and cannot escape through the windows, which increases the difficulty of rescue and reduces the survival rate of personnel

In this case, the protective net can only be cut off destructively to realize the rescue of personnel, and the damaged protective net can only be redone if it is to be restored, which increases the cost of use

[0004] 2. When it is necessary to carry out outdoor construction (such as the installation and maintenance of the outdoor unit of the air conditioner), due to the blockage of the protective net, the outdoors cannot be easily reached through the window, and the protective net can only be removed in a destructive way and then reinstalled. Restoration, increased construction cost and use cost

[0005] 3. After the installation of the non-detachable protective net, after a long period of use, its local strength and toughness will be irreversibly reduced, which can no longer meet the safety requirements, and must be replaced as a whole to recover, and the use and maintenance costs are high.

[0006] Due to the above-mentioned technical defects and other problems in the existing protective net, it has not been generally accepted by people, and it has not been popularized in a large area.
