Description

Technical Field

[0001] The utility model belongs to the technical field of protective nets, and in particular relates to a building construction protective net that can be quickly disassembled and assembled. Background Art

[0002] A construction project refers to an engineering entity formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. During the construction of a construction project, it is usually necessary to install a protective net on the construction scaffolding to prevent building materials from falling from the scaffolding and injuring construction workers on the ground.

[0003] Reference patent number: CN 220790684 U is a construction engineering construction protection net. This patent, through the cooperation between the protection net storage shell, the winding roller, the net slot, the circular rotating plate, the second U-shaped plate and the third screw, can adjust the unfolded size of the protection net body according to the size of the construction site when installing the protection net body, thereby ensuring that the protection net body can accurately and effectively protect the construction site. Through the cooperation between the first U-shaped plate, the second screw and the clamping plate, the unfolded protection net body can be easily fixed on the construction frame.

[0004] During use of the utility model, although the protective net is easy to adjust the size and install quickly, the side edges of the protective net lack support when the two storage shells (i.e., the first fixing rod and the second fixing rod) are separated. When a heavy object falls into the protective net, the sides of the protective net are easy to deform towards each other, causing the heavy object to slide from the sides. There is a lack of support mechanism for the protective net. At the same time, when the steel pipe rack becomes loose, it cannot provide timely reminders and there is a lack of an alarm mechanism, which poses certain safety hazards. Utility Model Content

[0009] As a preferred embodiment, the limiting assembly includes a pressure plate, and the first support rod and the second support rod are slidably connected with a pressure plate at one end close to the protective net, and the first support rod and the second support rod at the top are respectively movably connected with a fixing knob, and the fixing knob is threadedly connected to the bottom pressure plate, so as to facilitate fixing the protective net through the pressure plate.

[0010] As a preferred embodiment, a resistance ring is installed on the fixing knob, and the resistance ring is used to resist the end of the top pressure plate away from the protective net, so that a pair of pressure plates move toward each other, thereby firmly fixing the protective net.

[0011] As a preferred embodiment, a snap-fit ​​groove is provided at one end of the pressure plates close to each other, and the snap-fit ​​groove is used to snap-fit ​​with the woven steel wire on the protective net to increase the firmness of the fixation of the protective net, so that the woven steel wire of the protective net can be snapped into the snap-fit ​​groove, thereby limiting the detachment and movement.

[0012] As a preferred embodiment, a sliding frame is installed on the rack, the pressure sensor is installed on the sliding frame and connected to the rack, and a second spring is installed between the sliding frame and the first fixed rod, and the second spring is used to push the rack and the gear to engage, thereby preventing the gear from excessively pushing the rack to move and damaging the pressure sensor.

[0013] As a preferred embodiment, a screw is rotatably connected to the first fixed rod, and a resistance block is threadedly connected to the threaded end of the screw. The resistance block is slidably connected to the first fixed rod, and the resistance block is used to resist the sliding frame, so that the gear and the rack can be disengaged during transportation to release the alarm.

The first support rod and the second support rod rotate with each other to form a certain angle, and the fixing knob makes a pair of pressure plates contact each other, so as to clamp and fix the protective net firmly, and the buckling groove can buckle with the braided steel wire on the protective net, so as to increase the fixing firmness and avoid deformation of the protective net.

[0016] The utility model provides a buzzer, a pressure sensor, a gear and a rack. When the steel pipe rack becomes loose, the displacement between the first fixed rod and the second fixed rod will change, thereby causing the first support rod and the second support rod to rotate. The gear rotates to drive the rack to slide, thereby causing the sliding frame to pull or push the pressure sensor. The pressure sensor will generate a pressure electric signal under the limit of the first spring. When the pressure electric signal generated by the pressure sensor changes too much, the buzzer will sound an alarm to prompt that the steel pipe rack is loose, thereby facilitating timely reinforcement and increasing safety.
