Description

Technical Field

[0002] In the construction of conventional multi-storey and high-rise reinforced concrete houses, after the main structure construction such as beams, slabs and columns is completed, secondary structure construction such as masonry, structural columns and plastering will be carried out. During the secondary structure construction, it is inevitable to work at high altitudes. If the external frames of the construction elevator and other parts are removed too early before the masonry construction is carried out, there will be safety risks such as objects hitting and people falling from high altitudes. If there are no safe and stable protective measures, the quality of masonry construction cannot be guaranteed.

The protective net 100 is arranged on the facade of the building, vertically and in contact with the floor slab. It is a lightweight, high-strength, flexible mesh structure that can withstand the impact of an operator or an object accidentally falling and has a certain safety factor. The suspension mechanism 200 is located on the floor slab that needs to be constructed and is connected to the protective net 100. At least two suspension mechanisms 200 are arranged on each floor slab.

[0051] During actual installation, multiple suspension mechanisms 200 are first fixed on the floor to be constructed according to the construction situation, and then the protection net 100 is connected to the suspension mechanism 200. The connected protection net 100 is perpendicular to the floor and fits tightly with the edge of the floor.

[0052] In some embodiments, Figure 2 As shown, the above-mentioned suspension mechanism 200 is optimized.

[0053] In fact, the protective net connector 3 in this embodiment is two U-shaped hooks with a diameter of 10 cm, which are placed side by side with a spacing of 20 cm and welded to the suspension beam 1. In particular, in the suspension mechanism 200 located on the roof of the construction building, the protective net connector 3 is welded above the suspension beam 1; in the suspension mechanism 200 located on the first floor of the construction building, the protective net connector 3 is welded below the suspension beam 1;

[0054] During actual installation, use a safety rope made of nylon or cotton material to fix the protective net 100 and the protective net connector 3 together, adjust the distance between the front end of the suspension mechanism 200 and the edge of the floor, so that the edge of the protective net 100 connected to the rear U-shaped hook fits with the edge of the floor.

[0055] In some embodiments, Figure 1 , 2 As shown, the bracket 2 is optimized. In this embodiment, the height of the bracket 2 is adjustable, and the installation height of the suspension beam 1 can be adjusted according to the waterproof requirements of the floor masonry or the height of the flip beam.

[0056] During actual construction, the masonry waterproofing requirements and the height of the flip beam will affect the installation height of the suspension beam 1. Different construction sites have different masonry waterproofing requirements and flip beam heights. This embodiment adjusts the installation height of the suspension beam 1 by adjusting the height of the bracket 2 to adapt to different construction conditions.

[0057] Furthermore, if Figure 5 , 6 As shown, the bracket 2 is optimized. In this embodiment, the bracket 2 includes an upper bracket 21 and a lower bracket 22. The upper bracket 21 is connected to the suspension beam 1; the lower bracket 22 is connected to the floor slab; the lower end of the upper bracket 21 is vertically and adjustably inserted into the upper end of the lower bracket 22.

[0058] During actual installation, the height of the bracket 2 is adjusted by adjusting the insertion depth of the upper bracket 21 and the lower bracket 22. The structure is simple, stable and controllable, and easy to install and disassemble.

[0059] In some embodiments, Figure 5 As shown, the upper bracket 21 is optimized. In this embodiment, the upper bracket 21 includes a cross-beam connecting tube 21a, a first vertical connecting tube 21b and a first reinforcement 21c. The cross-beam connecting tube 21a is connected to the suspension beam 1; one end of the first vertical connecting tube 21b is welded to the cross-beam connecting tube 21a, and the other end is vertically adjustably inserted into the upper end of the lower bracket 22; the first reinforcement 21c is welded to the cross-beam connecting tube 21a on one side and to the first vertical connecting tube 21b on the other side.

[0060] During actual installation, the cross beam connecting pipe 21a adopts a channel steel with a length of about 60 cm and a model of 90mm×90mm×4mm. A hole with a diameter of 20mm is opened in the center of both sides of the channel steel every 20 cm, which is convenient for connecting with the suspension beam 1 through bolts; the first vertical connecting pipe 21b adopts a square steel with a model of 70mm×70mm×4mm, and a hole with a diameter of 20mm is opened in the center line of the side every 10 cm, which is convenient for connecting with the lower bracket 22 and adjusting the height; the first reinforcement 21c adopts a triangular steel plate with a flank to strengthen the stability of the connection between the cross beam connecting pipe 21a and the first vertical connecting pipe 21b.

[0061] In some embodiments, Figure 6 , 7 As shown, the lower bracket 22 is optimized. In this embodiment, the lower bracket 22 includes a floor connecting pipe 22a, a second vertical connecting pipe 22b and a second reinforcement 22c.

[0064] During actual installation, adding a counterweight bracket 4 can increase the impact resistance of the suspension mechanism 200; the distance between the counterweight bracket 4 and the bracket 2 is much greater than the distance between the bracket 2 and the edge of the floor slab, which can effectively increase the impact resistance torque of the counterweight bracket 4, thereby improving the reliability and safety of the protective device.

[0065] In some embodiments, Figure 7As shown, the counterweight bracket 4 is optimized. In this embodiment, the counterweight bracket 4 has the same structure as the bracket 2. Two counterweight rods 41 are connected to the lower bracket 22 of the counterweight bracket 4, and a plurality of counterweight blocks 42 are connected to the counterweight rods 41.

When conditions permit, the counterweight block 42 can be made of metal with high density and high hardness such as steel; after the counterweight block 42 is placed, a steel wire rope is used to pass through the hole on the floor connection pipe 22a and the top of the counterweight rod 41 to form a closed loop to fix the counterweight rod 41 and the counterweight block 42 together.

[0067] In some embodiments, Figure 4 As shown, the suspension beam 1 is optimized. In this embodiment, the suspension beam 1 includes a front beam 11, a rear beam 12 and a connecting beam 13. A protective net connecting member 3 is provided on the front beam 11.

[0069] In some embodiments, Figure 1 , 2 As shown, the high-altitude edge masonry construction protection device is optimized. In this embodiment, the high-altitude edge masonry construction protection device also includes a sensor alarm 300. The sensor alarm 300 is fixed at the bottom of the floor or under the structural beam near the edge of the floor, and is used to remind the workers when they enter a certain range from the edge of the floor.

[0070] In fact, in this embodiment, the sensor alarm 300 is an infrared sensor voice prompter powered by a rechargeable battery that can be purchased on the market. The sensor alarm 300 can be installed at the bottom of the floor or under the structural beam near the edge of the floor. Multiple sensor alarms 300 can be installed on the same construction floor; when construction workers enter within 1.5m from the edge of the floor, the sensor alarm 300 can sound an alarm to remind the construction workers to pay attention to safety, prevent falling, and wear safety protection equipment.
