Description
Technical Field
[0001] This utility model relates to the field of protective netting technology, and in particular to a protective netting for construction projects. Background Technology
[0002] Construction engineering refers to the physical engineering project formed by the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines and equipment. In order to protect the safety of construction workers during the construction process, protective nets need to be installed at high-rise buildings or deep pits.
[0003] Existing construction safety nets are installed by connecting multiple nets together with connecting posts to surround the danger zone and protect pedestrians and construction workers. However, because the size of the nets is fixed, the nets may not be long enough or the angle may not be suitable after installation, resulting in gaps between the net and the building or another net. This leaves the gap area unprotected and affects the protection of personnel. Utility Model Content
[0004] The technical problem this utility model aims to solve is that, due to the fixed size of the protective net, the length of the protective net may be insufficient or the angle may be unsuitable after installation, resulting in gaps between the protective net and the building or another protective net, causing the gap area to be unprotected and affecting the protection effect on personnel.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a protective net for construction projects, comprising: a protective net body, which is installed and fixed on the ground by connecting columns to provide protection for personnel, wherein the protective net body is composed of a first protective net and a second protective net; and an adjustment component, wherein the adjustment component is disposed between the first protective net and the second protective net, and the length and size of the protective net body are adjusted by changing the distance between the first protective net and the second protective net.
[0006] Preferably, the adjusting assembly includes: two shaft brackets, which are respectively fixed to adjacent sides of the first guardrail and the second guardrail; two round hole rods, which are respectively rotatably mounted on the two shaft brackets via bearings; a round tube, which is fixed to the round hole rod near the first guardrail; and a round rod, which is fixed to the round hole rod near the second guardrail, and the round rod slides inside the round tube.
[0007] The effect achieved by the above components is as follows: By setting the adjustment assembly, the first protective net is first fixed to the ground by the connecting post. At this time, the second protective net is manually pulled, causing the second protective net to move the shaft frame away from the first protective net. This causes the shaft frame to move the round hole rod and the round rod, allowing the round rod to slide along the inside of the round tube. When the second protective net moves to a position that is close to or in contact with the building or another protective net body, the second protective net is fixed to the ground by another connecting post, changing the distance between the first and second protective nets. This completes the length adjustment of the protective net body. At the same time, the round tube and the round rod cooperate with each other. The system fills the gap between the first and second protective nets, providing interception and protection for personnel. Simultaneously, the rotational nature of the shaft and the perforated rod allows for adjustment of the angle between the first and second protective nets, enabling angle adjustment of the protective net body itself. This allows the protective net body to flexibly handle various arc or right-angle areas, reducing situations where the net body is insufficient in length or mismatched in size after installation, resulting in gaps between the net body and the building or another protective net body, thus affecting the protection of personnel. This improves the installation flexibility and ease of use of the protective net body.
[0008] Preferably, the adjusting assembly further includes a cutting ring, wherein the cutting ring is fixed to the opening of the round tube, and wherein the cutting ring is sleeved on the round rod and conforms to the surface of the round rod to remove the adhering impurities.
[0009] The effect achieved by the above-mentioned components is that by setting the cutting ring, the cutting ring can scrape off the adhering impurities by adhering to the surface of the round rod during its movement, thereby reducing the situation where impurities enter the interior of the round tube and increase friction.
[0010] Preferably, the adjusting assembly further includes: a protrusion, wherein the protrusion is fixed to the round rod; and a slide, wherein the slide is formed on the round tube, and the protrusion is placed inside the slide to limit the movement of the round rod.
[0011] The effect achieved by the above components is that by setting up protrusions and slides, the protrusions can slide left and right inside the slides and intercept and limit the round rod, reducing the possibility of the round rod shaking or falling out of the round tube.
[0012] Preferably, the adjustment assembly further includes two positioning pins, wherein the two positioning pins are slidably mounted on the bottom of the two circular hole rods, and the end of the positioning pin near the ground is conical.
[0013] The effect achieved by the above-mentioned components is as follows: by setting positioning pins, personnel can insert the positioning pins into the ground to assist in limiting the positioning of the round hole rods after the two round hole rods have been adjusted, and at the same time, the middle position of the first and second protective nets is reinforced, thereby improving the stability of the middle area of the protective net body.
[0014] Preferably, both positioning pins have multiple barbs fixedly connected to their surfaces, and the surfaces of the barbs are triangular.
[0015] The effect achieved by the above-mentioned components is that by setting barbs, the barbs can be inserted into the soil along with the positioning pin, increasing the resistance between the positioning pin and the soil and reducing the possibility of the positioning pin slipping.
[0016] Preferably, it further includes: a protective component, the protective component comprising: a perforated plate, wherein bolts are provided inside the perforated plate, wherein the bolts are screwed into threaded grooves opened on the protective net body to fix the perforated plate; and a rubber pad, wherein the rubber pad is fixed to the perforated plate.
[0017] The effects achieved by the above components are as follows: By setting up the protective components, the perforated plate is first manually moved to a position where it fits against the surface of the protective net body, so that the inner wall of the perforated plate coincides with the inner wall of the threaded groove. At this time, the bolts are manually screwed into the perforated plate and the threaded groove to fix the position of the perforated plate and the rubber pad, thus fixing the perforated plate and the rubber pad to the protective net body. When an object or person collides with the protective net body, the rubber pad intercepts the object or person, preventing direct contact between the object or person and the protective net body. Utilizing the high elasticity of the rubber, it deforms upon impact, converting mechanical energy into heat energy for dissipation, effectively attenuating vibration waves, reducing energy transfer, and lowering the impact intensity. This achieves further protection for the protective net body, objects, or personnel, reducing the possibility of objects directly colliding with the protective net body and causing deformation or damage to the protective net body. At the same time, it can reduce the injury caused to personnel when the protective net body collides with personnel, improving the protection effect for personnel.
[0018] Preferably, the protective component further includes an auxiliary block, wherein the auxiliary block is uniformly fixed to the nut of the bolt.
[0019] The effect achieved by the above-mentioned components is that by setting up auxiliary blocks, the hands can be stopped, reducing the chance of slipping when personnel manually turn the bolts.
[0020] The beneficial effects of this utility model are:
[0021] By setting adjustment components, the length and angle of the protective net body can be flexibly changed, making the protective net body adaptable to various ground surfaces and scenarios. This reduces the possibility of insufficient length or unsuitable angle of the protective net body after installation, resulting in gaps between the protective net body and the building or another protective net body, which would leave the gap area unprotected and affect the protection effect on personnel. This improves the installation flexibility and ease of use of the protective net body. Attached Figure Description

[0030] Figure 1-4 The protective netting for construction projects shown includes: a protective netting body 1, which is installed and fixed on the ground via connecting posts 2 to provide protection for personnel, wherein the protective netting body 1 is composed of a first protective net 11 and a second protective net 12; and an adjustment component 3, wherein the adjustment component 3 is disposed between the first protective net 11 and the second protective net 12, and the length and size of the protective netting body 1 are adjusted by changing the spacing between the first protective net 11 and the second protective net 12.
[0031] Figure 2 and Figure 3The adjustment assembly 3 shown includes: two shaft brackets 31, which are respectively fixed to the adjacent sides of the first protective net 11 and the second protective net 12; two round hole rods 32, which are respectively rotatably mounted on the two shaft brackets 31 via bearings; a round tube 33, which is fixed to the round hole rod 32 on the side near the first protective net 11; and a round rod 38, which is fixed to the round hole rod 32 on the side near the second protective net 12, and the round rod 38 slides inside the round tube 33. By setting the adjustment assembly 3, the first protective net 11 is first fixed to the ground by the connecting column 2. At this time, the second protective net 12 is manually pulled, so that the second protective net 12 drives the shaft brackets 31 to move away from the first protective net 11, so that the shaft brackets 31 drive the round hole rods 32 and the round rod 38 to move, so that the round rod 38 slides along the inside of the round tube 33. When the second protective net 12 moves to the side of the building or another protective net body 1, the adjustment assembly 31 is adjusted to allow the adjustment assembly 32 to be adjusted to allow the adjustment assembly 3 ... When the netting is in close proximity to the ground, another connecting post 2 is used to fix the second protective netting 12 to the ground, thereby changing the distance between the first protective netting 11 and the second protective netting 12. This allows for the adjustment of the length of the protective netting body 1. At the same time, the round tube 33 and the round rod 38 work together to fill the gap between the first protective netting 11 and the second protective netting 12, providing interception protection for personnel. The rotation between the shaft bracket 31 and the round hole rod 32 can be used to adjust the angle between the first protective netting 11 and the second protective netting 12, thereby adjusting the angle of the protective netting body 1. This allows the protective netting body 1 to flexibly handle various arc or right angle areas, reducing the possibility of insufficient length or mismatched size after installation, which could result in gaps between the protective netting body 1 and the building or another protective netting body 1, leaving the gap area unprotected and affecting the protection effect on personnel. This improves the installation flexibility and ease of use of the protective netting body 1.
[0032] Figure 2 and Figure 3 The adjustment assembly 3 also includes: a cutting ring 34, which is fixedly connected to the opening of the round tube 33. The cutting ring 34 is sleeved on the round rod 38 and adheres to the surface of the round rod 38 to remove adhering impurities. By setting the cutting ring 34, the cutting ring 34 can adhere to the surface of the round rod 38 during its movement to scrape off the adhering impurities, reducing the possibility of impurities entering the interior of the round tube 33 and increasing friction. The adjustment assembly 3 also includes: a protrusion 39, which is fixedly connected to the round rod 38; and a slide 35, which is opened on the round tube 33. The protrusion 39 is placed inside the slide 35 to limit the movement of the round rod 38. By setting the protrusion 39 and the slide 35, the protrusion 39 can slide left and right inside the slide 35 and intercept and limit the movement of the round rod 38, reducing the possibility of the round rod 38 shaking or falling out of the interior of the round tube 33.
[0033] Figure 2 and Figure 3The adjustment component 3 shown also includes two positioning pins 36, which are slidably installed at the bottom of two round hole rods 32. The end of the positioning pin 36 near the ground is conical. By setting the positioning pins 36, personnel can insert the positioning pins 36 into the ground to assist in limiting the round hole rods 32 after the two round hole rods 32 have been adjusted. At the same time, the middle position of the first protective net 11 and the second protective net 12 is reinforced, improving the stability of the middle area of the protective net body 1. Multiple barbs 37 are fixedly connected to the surface of each of the two positioning pins 36. The surface of the barbs 37 is triangular. By setting the barbs 37, the barbs 37 can be inserted into the soil along with the positioning pins 36, increasing the resistance between the positioning pins 36 and the soil and reducing the possibility of the positioning pins 36 sliding.
[0034] Figure 3 and Figure 4 The system also includes: a protective component 4, comprising: a perforated plate 41, with bolts 43 inside the perforated plate 41, wherein the bolts 43 are screwed into the threaded grooves 45 on the protective net body 1 to fix the perforated plate 41; and a rubber pad 42, wherein the rubber pad 42 is fixed to the perforated plate 41. By setting the protective component 4, the perforated plate 41 is first manually moved to a position where it is in contact with the surface of the protective net body 1, so that the inner wall of the perforated plate 41 coincides with the inner wall of the threaded groove 45. At this time, the bolts 43 are manually screwed into the positions of the perforated plate 41 and the threaded groove 45 to fix the positions of the perforated plate 41 and the rubber pad 42, thereby fixing the perforated plate 41 and the rubber pad 42. Fixed to the protective net body 1, when an object or person collides with the protective net body 1, the rubber pad 42 intercepts the object or person, preventing direct contact between the object or person and the protective net body 1. Utilizing the high elasticity of the rubber, it deforms upon impact, converting mechanical energy into heat energy for dissipation, effectively attenuating vibration waves, reducing energy transfer, and lowering impact intensity. This achieves further protection for the protective net body 1, the object, or the person, reducing the likelihood of objects directly colliding with the protective net body 1 and causing deformation or damage to it. At the same time, it can reduce the injury to personnel when the protective net body 1 collides with them, improving the protection effect for personnel.
[0035] Figure 3 and Figure 4 The protective component 4 shown also includes an auxiliary block 44, which is uniformly fixed to the nut of the bolt 43. By setting the auxiliary block 44, the hand can be blocked, reducing the chance of the hand slipping when the person manually turns the bolt 43.
[0036] Working principle: First, the first protective net 11 is fixed to the ground by the connecting post 2. Then, the second protective net 12 is manually pulled, causing the second protective net 12 to move the shaft frame 31 away from the first protective net 11. This causes the shaft frame 31 to move the round hole rod 32 and the round rod 38, allowing the round rod 38 to slide along the inside of the round tube 33. When the second protective net 12 moves to a position that is close to or in contact with the building or another protective net body 1, the second protective net 12 is fixed to the ground by another connecting post 2, changing the distance between the first protective net 11 and the second protective net 12. This completes the length adjustment of the protective net body 1. At the same time, the round tube 33 and the round rod 38 work together to fill the gap between the first protective net 11 and the second protective net 12, providing interception protection for personnel. The rotation between the shaft frame 31 and the round hole rod 32 can also be used to adjust the angle between the first protective net 11 and the second protective net 12, thereby achieving angle adjustment of the protective net body 1.
[0037] First, manually move the perforated plate 41 to a position where it fits against the surface of the protective net body 1, so that the inner wall of the perforated plate 41 coincides with the inner wall of the threaded groove 45. Then, manually screw the bolt 43 into the perforated plate 41 and the threaded groove 45 to fix the perforated plate 41 and the rubber pad 42 in place, thus fixing the perforated plate 41 and the rubber pad 42 onto the protective net body 1. When an object or person collides with the protective net body 1, the rubber pad 42 intercepts the object or person, preventing direct contact between the object or person and the protective net body 1. Utilizing the high elasticity of the rubber, it deforms upon impact, converting mechanical energy into heat energy for dissipation, effectively attenuating vibration waves, reducing energy transfer, and lowering the impact intensity, thereby achieving further protection for the protective net body 1, the object, or the person.
[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
