Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a falling object interception device for buildings. Background Technique

[0002] In some old communities with high and dense buildings, due to high occupancy rates and mixed populations, incidents of falling objects injuring people occur frequently. Especially in some places where there are windows above the walkways, in order to install, a shielding net will be installed to intercept falling objects. Since the structure and function of the shielding net are simple, for falling objects dropped from particularly high floors, during the falling process of the falling object, due to the conversion of gravitational potential energy into kinetic energy, the speed of the falling object when it contacts the shielding net is very high. Due to the interception of the shielding net, the impact force of the falling object on the shielding net is very large. There is no buffer mechanism on the shielding net, and the firmness of the shielding net is not enough, so it is easy for the falling object to break through the shielding net, which is not conducive to the service life of the shielding net to intercept falling objects and reduces safety. Therefore, a falling object interception device for buildings is needed to meet the requirements. Content of the Utility Model

[0003] The purpose of the utility model is to solve the shortcoming of poor safety of the shielding net when intercepting falling objects in the prior art, and to propose a falling object interception device for buildings.

Enclosing plates are fixed at the peripheral edges of the second grid plate. Adjacent two enclosing plates are fixed together. An anti-offset component is jointly provided on each enclosing plate and the second grid plate and the first grid plate.

[0006] Preferably, the anti-offset component includes a plurality of insertion holes. The plurality of insertion holes are all arranged on the enclosing plate and the second grid plate. An insertion rod is inserted in each insertion hole. The plurality of insertion rods are all fixed on the first grid plate.

[0007] Preferably, a first baffle is provided below the support frame. A plurality of locking components are fixed on the first baffle. The plurality of locking components are respectively fixed on the plurality of support legs.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Embodiment 1: Refer to Figures 1-3, A falling object interception device for buildings, including a support frame 1 and multiple support legs 2. Multiple support legs 2 are all fixed on the support frame 1. A first grid plate 3 is fixed on the support frame 1. Multiple springs 4 are evenly fixed on the first grid plate 3. A second grid plate 5 is fixed on multiple springs 4. By setting multiple springs 4, the impact force when the falling object drops is buffered, the damage to the second grid plate 5 and the first grid plate 3 caused by the impact force when the falling object drops is reduced, and the effective service life is extended. Peripheral edges of the second grid plate 5 are all fixed with enclosing plates 6. Adjacent two enclosing plates 6 are fixed together. The setting of multiple enclosing plates 6 blocks the falling objects on the second grid plate 5, so that the falling objects on the second grid plate 5 will not fall onto the ground outside the second grid plate 5 due to elasticity;

[0019] Each enclosing plate 6 and the second grid plate 5 and the first grid plate 3 are all jointly provided with an anti-offset component. The setting of multiple anti-offset components enables the second grid plate 5 to move up and down in a straight line when moving, so that the positions between the second grid plate 5 and the first grid plate 3 will not be skewed. The anti-offset component includes multiple insertion holes 8. Multiple insertion holes 8 are all arranged on the enclosing plate 6 and the second grid plate 5. An insertion rod 7 is inserted in each insertion hole 8. Multiple insertion rods 7 are all fixed on the first grid plate 3. The cooperation of multiple insertion rods 7 and multiple insertion holes 8 restricts the movement route of the second grid plate 5, and at the same time protects multiple springs 4, so that multiple springs 4 will not be damaged even when the second grid plate 5 is unevenly stressed.

[0020] During use, if the aisle is long, multiple such falling object interception devices for buildings are used side by side, and there should be no gaps between adjacent two support frames 1, and they should be closely attached together. When the falling object drops, it first contacts the second grid plate 5. The setting of multiple enclosing plates 6 enables the falling object not to fall from the edge of the second grid plate 5. When the impact force of the falling object acts on the second grid plate 5, the second grid plate 5 moves towards the first grid plate 3. The lengths of multiple insertion rods 7 inserted in multiple insertion holes 8 gradually increase, and multiple springs 4 are also compressed. By setting the second grid plate 5 and the first grid plate 3 to form a double-layer protection, the effect of falling object interception is increased, and multiple springs 4 are also arranged between the second grid plate 5 and the first grid plate 3 to buffer the impact force when the falling object drops, so as to reduce the damage to the second grid plate 5 and the first grid plate 3 caused by the impact force when the falling object drops, and extend the effective service life.

[0021] Embodiment 2: In Embodiment 1, although the double-layer protection of the second grid plate 5 and the first grid plate 3 is set, for fragile falling objects, due to the interception of the second grid plate 5 and the first grid plate 3, they will break into multiple pieces and then pass through the second grid plate 5 and the first grid plate 3, which will instead increase the area of hurting people. Refer to Figure 1 、 2And 4, as another preferred embodiment of the present utility model, is different from Embodiment 1 in that a first baffle 9 is provided below the support frame 1, and a plurality of locking components are fixed on the first baffle 9. The plurality of locking components are respectively fixed on a plurality of support legs 2. The first baffle 9 is of an arc structure and is made of transparent acrylic plate. Two second baffles 10 are symmetrically fixed on the first baffle 9. The cooperation of the arc-shaped first baffle 9 and the two second baffles 10 intercepts the debris passing through the second grid plate 5 and the first grid plate 3, so that the debris passing through the second grid plate 5 and the first grid plate 3 will not fall to the ground below the first grid plate 3. A plurality of holes 18 are provided through each of the second baffles 10. The arrangement of the plurality of holes 18 reduces the water blocking ability of the two second baffles 10, enables the rainwater falling on the first baffle 9 to fall faster, and reduces the pressure on the first baffle 9;

[0022] The locking component includes a fixing block 11 fixed on the first baffle 9. A first clamping plate 12 is fixed on the fixing block 11. Two first fixing plates 14 are symmetrically fixed on the first clamping plate 12. Two bolts 16 are symmetrically fixed on each of the two first fixing plates 14. Each two bolts 16 jointly penetrate through a second fixing plate 15. A second clamping plate 13 is jointly fixed on the two second fixing plates 15. A nut 17 is provided on each bolt 16. By tightening a plurality of nuts 17, the plurality of second clamping plates 13 and the plurality of first clamping plates 12 respectively clamp on the plurality of support legs 2 to fix the heights of the first baffle 9 and the two second baffles 10. When it is necessary to clean the falling objects intercepted on the first baffle 9, loosen the plurality of nuts 17 to make the clamping force between each second clamping plate 13 and each first clamping plate 12 on each support leg 2 become loose, and pulling can reduce the height of the first baffle 9, facilitating the staff to clean the falling objects intercepted on the first baffle 9.

[0023] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
