Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building construction net. Background Art

[0002] During construction, there is a high probability of falling objects from high altitudes. In order to ensure the safety of personnel entering and exiting the construction site, it is necessary to set up a building net to protect the area around the building, block falling objects from high altitudes, and ensure the safety of construction personnel entering and exiting the site. At present, by setting up a blocking net around the building, the blocking net is fixed to the four sides of the building by ropes, and the falling objects falling during construction can be intercepted by the blocking net.

[0003] According to the "A kind of construction net" proposed in application number CN202322348963.8, the impact force on the barrier net can be converted into elastic potential energy, avoiding damage to the barrier net due to excessive instantaneous impact force and increasing the service life of the barrier net; the reel can rotate to recycle the barrier net and use the plug rod to insert into the core shaft, so that the plug rod also plays the role of locking the reel.

[0004] However, when the impact force of the falling object is too large, the elastic potential energy converted is also large. The elastic potential energy will restore the barrier net again, causing the falling object to bounce again, and the bounce direction is uncertain, resulting in insufficient safety. Therefore, in response to the above phenomenon, a construction net is proposed to meet the needs of actual use. Utility Model Content

DETAILED DESCRIPTION

[0019] Embodiment 1, by Figure 1-4 The utility model comprises a mounting base 1 and a blocking net 2, a support plate 11 is fixedly mounted on the side of the mounting base 1, a card slot 12 and a slide slot 13 are provided on the support plate 11, the blocking net 2 comprises a flexible net 21, a first cross bar 22 and a second cross bar 24 are fixedly mounted on both sides of the flexible net 21, a first anti-slipping head 23 is fixedly mounted on both ends of the first cross bar 22, a second anti-slipping head 25 is fixedly mounted on both ends of the second cross bar 24, the first cross bar 22 is movably clamped in the card slot 12, the second cross bar 24 is movably mounted in the slide slot 13, an elastic component 15 and an energy-consuming component 16 are provided on the side of the support plate 11, and one end of the elastic component 15 is movably connected to the energy-consuming component 16.

[0020] In this embodiment, after the falling object body 100 falls on the flexible net 21, the deformation of the flexible net 21 itself and the movement of the second cross bar 24 drive the elastic component 15 to deform and store energy, and the energy-absorbing component 16 does not affect the shortening of the elastic component 15, but limits the recovery speed of the elastic component 15, so that the elastic potential energy of the elastic component 15 is not released immediately, thereby preventing the falling object body 100 from bouncing too high a height on the flexible net 21, thereby improving the safety of the barrier net 2.

[0021] The elastic component 15 includes a guide rod 151, a piston 152 is fixedly mounted on one end of the guide rod 151, a mounting ring 153 is fixedly mounted on the surface of the guide rod 151, a spring body 154 is arranged on the side of the mounting ring 153, and the spring body 154 is movably sleeved on the surface of the guide rod 151. The surface of the guide rod 151 is movably sleeved with a mounting sleeve 155 and a limiting sleeve 156, the side of the mounting ring 153 is fitted with the side of the limiting sleeve 156, one end of the spring body 154 is movably sleeved on one side of the mounting sleeve 155, and the mounting sleeve 155 and the limiting sleeve 156 are both fixedly mounted on the side of the support plate 11.

[0022] In this embodiment, after one end of the guide rod 151 is subjected to force, the spring body 154 is compressed by the mounting ring 153 , and the guide rod 151 is guided and limited by the mounting sleeve 155 and the limiting sleeve 156 .

[0023] A mounting fastener 17 is fixedly installed at one end of the guide rod 151, and both ends of the second cross bar 24 are movably installed inside the mounting fastener 17. A fastening screw 171 is threadedly installed on the side of the mounting fastener 17. A mounting buckle plate 14 is fixedly installed at one end of the support plate 11, and the second cross bar 24 can be easily removed and installed through the set mounting buckle plate 14.

[0024] In this embodiment, the mounting fasteners 17 are two semicircular locks, and the second cross bar 24 can rotate in the mounting fasteners 17 to achieve the reeling of the flexible net 21. In addition, the second cross bar 24 can be fixed by the set fastening screws 171 to control the tension of the flexible net 21.

[0025] The energy-absorbing component 16 includes an energy-absorbing shell 161 . A mounting groove 18 is provided on the side of the support plate 11 . A fastening plate 19 is fixedly installed on the side of the support plate 11 . The energy-absorbing shell 161 is clamped in the fastening plate 19 . Both ends of the energy-absorbing shell 161 fit with the inner walls of both sides of the mounting groove 18 .

[0026] In this embodiment, the energy dissipation component 16 is fixed by using the mounting groove 18 and the fastening plate 19 .

[0027] The inner wall of the energy-absorbing shell 161 is integrally formed with a limiting protrusion 162, the piston 152 is movably installed inside the energy-absorbing shell 161, a control head 163 is threadedly installed on the surface of the energy-absorbing shell 161, a side groove 164 is provided on the side of the control head 163, and the side groove 164 is connected to the interior of the energy-absorbing shell 161, a floating plate 165 is movably installed inside the control head 163, and a center hole 166 is provided in the middle of the floating plate 165.

[0028] In this embodiment, Figure 3 As shown, when the piston 152 moves from right to left in the energy-absorbing shell 161, the gas inside the energy-absorbing shell 161 will be discharged through the central hole 166. However, since the diameter of the central hole 166 is small, the floating plate 165 is lifted up by air pressure, and the air inside the energy-absorbing shell 161 can be quickly discharged from the side groove 164, so that the movement of the piston 152 from right to left is slightly affected, and the elastic component 15 can store energy normally.

[0029] When the piston 152 moves from left to right in the energy-absorbing shell 161, the outside air enters the interior of the energy-absorbing shell 161 through the center hole 166. However, due to the small diameter of the center hole 166, the movement speed of the piston 152 is limited, thereby slowing down the reset speed of the elastic component 15 and reducing the height to which the barrier net 2 bounces the falling object body 100.

[0030] Working principle: After the falling object body 100 falls on the flexible net 21, the deformation of the flexible net 21 itself and the movement of the second cross bar 24 drive the elastic component 15 to deform and store energy, and the energy-absorbing component 16 does not affect the shortening of the elastic component 15, but limits the recovery speed of the elastic component 15, so that the elastic potential energy of the elastic component 15 will not be released immediately, thereby preventing the falling object body 100 from bouncing too high a height on the flexible net 21, thereby improving the safety of the barrier net 2.
