Description

Technical Field

[0001] The utility model relates to the technical field of protection nets, in particular to a safety protection net for high-rise buildings. Background Art

[0002] The safety of high-rise building construction workers is a top priority. Safety nets play a crucial role during construction, especially at height. Currently, a common protective measure involves laying safety nets on scaffolding and tying them to the scaffolding with ropes. However, during the tying process, workers may not secure the ropes tightly enough, and after extended use, the ropes may become loose, compromising the net's effectiveness. Furthermore, when the net is subjected to external forces, the forces acting at the ties are concentrated, creating large gaps between the net and the scaffolding, potentially damaging the net. Utility Model Content

[0003] In order to solve the technical problems in the above background technology that the connection between the protective net and the scaffolding is poor and the protective net is prone to damage due to uneven force around the protective net, the utility model provides a high-rise building safety net.

[0004] The technical solution of this utility model is as follows:

[0005] A high-rise building safety net includes a bracket and a rectangular grid-shaped net on it; the bracket includes four strip-shaped connecting rods, the connecting rods are "S"-shaped and pass through the mesh holes on the side of the net, and the four connecting rods are in a rectangular structure connected end to end; the connecting rods are also provided with fixing buckles that can be connected to scaffolding.

[0006] By passing the connecting rod through the mesh of the protective net in an "S" shape, when the protective net is subjected to external force, the connecting rod can disperse the force borne by the protective net and transmit it to the scaffolding through the fixing buckle, and the point-like force concentrated at the edge connection of the protective net during the original bundling connection is changed into a linear force, the force on the edge of the protective net is more balanced, and the stability of the connection between the protective net and the scaffolding is improved.

[0007] Specifically, the connecting rod comprises a cylindrical body with a latching plate at one end and a slot at the other end that engages with the latching plate. The cylindrical body creates relatively low friction with the netting, and the absence of sharp edges reduces wear on the netting. The latching plate and slot allow for quick positioning of two adjacent connecting rods, facilitating installation.

[0008] Furthermore, the platform is provided with first through-holes extending through both sides thereof, and the two opposing side walls of the slot are provided with second through-holes extending through both sides of the connecting rod. When the platform and slot are engaged, the first through-holes and the second through-holes intersect. The inner walls of the first through-holes and the second through-holes are both threaded. When the platform and slot are engaged, fastening bolts can be passed sequentially through the first through-holes and the second through-holes to securely connect the two connecting rods, providing a relatively strong connection.

[0009] Specifically, the fixing buckle comprises a main body with two arc-shaped notches on one side. Locking members are located outside the notches, respectively, to secure the connecting rod and scaffolding within the two notches. Connecting the scaffolding and connecting rod via these fixing members replaces the direct tying of the scaffolding and netting with straps, enhancing overall stability. Furthermore, the notches are designed to match the dimensions of the scaffolding and connecting rod, enabling quick and efficient installation and ensuring reusability.

[0010] Further preferably, rubber strips are provided on the inner walls of the two notches to increase the friction coefficient between the scaffolding and the connecting rod and the inner walls of the notches, thereby playing an anti-slip role.

[0011] As a preferred embodiment, a plurality of fixing buckles are provided on any of the connecting rods along the length direction of the connecting rod, and the fixing buckles are equidistantly arranged so that the force exerted on the connecting rod can be transmitted to the scaffolding more evenly, while ensuring that a stable connection effect can be maintained between the connecting rod and the scaffolding after a fixing buckle is damaged.

[0012] Furthermore, the protective net includes a plurality of mesh belts that are crisscrossed in both directions, and the mesh belts are arranged in an equidistant array along the longitudinal and transverse directions to ensure that the tensile strength of the protective net in different directions is consistent.

[0013] As a preferred embodiment, the surface of the protective net is coated with a flame retardant antistatic coating, which can prevent fires caused by electric welding sparks.

[0014] Through the above design, the beneficial effects of the high-rise building safety net of the utility model are:

[0015] (1) When the guard net is subjected to external force, the connecting rod can disperse the force borne by the guard net and transmit it to the scaffolding, changing the point-like force of the original binding connection method into a linear force form. The force on the edge of the guard net is more balanced. At the same time, the fixed buckle is used instead of the rope binding method to improve the stability of the connection between the guard net and the scaffolding.

[0016] (2) The connecting rod is inserted into the mesh on the side of the protective net in an S-shaped manner. The S-shaped insertion method realizes the movable connection between the protective net and the connecting rod. During transportation, the protective net and the connecting rod can be packed and transported separately, which is convenient and fast. Moreover, the connecting rod can be connected and assembled end to end, and can adapt to protective nets of different sizes and protection requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example

[0026] Combine Figure 1 This embodiment provides a high-rise building safety net 2, including a bracket 1 and a rectangular grid-shaped protective net 2 thereon. The protective net 2 is connected to the scaffolding through the bracket 1, and the protective net 2 and the bracket 1 are detachably connected.

[0027] Furthermore, the protective net 2 includes a plurality of mesh belts 21 that are crisscrossed in both directions. The mesh belts 21 are arranged in an equidistant array along the longitudinal and transverse directions to ensure that the tensile strength of the protective net 2 in different directions is consistent.

[0028] As a preferred embodiment, the surface of the protective net 2 is coated with a flame retardant antistatic coating, which can prevent fires caused by electric welding sparks.

[0029] In this embodiment, the bracket 1 includes four bar-shaped connecting rods 11. The connecting rods 11 are arranged in an "S" shape and pass through the mesh holes on the side of the protective net 2. The four connecting rods 11 form a rectangular structure connected end to end. By inserting the connecting rods 11 in the mesh holes of the protective net 2 in an "S" shape, when the protective net 2 is subjected to external forces, the connecting rods 11 can disperse the forces exerted on the protective net 2. This converts the concentrated point-like forces at the edge connection of the protective net 2 when the binding connection is used into linear forces, resulting in a more balanced force on the edge of the protective net 2.

[0030] Specifically, combined Figure 2 The connecting rod 11 includes a cylindrical rod body 111, one end of which is provided with a clamping platform 112, and the other end is provided with a clamping groove 113 that can be clamped with the clamping platform 112. The friction between the cylindrical rod body 111 and the protective net 2 is relatively small, and there are no sharp edges and corners, which reduces wear on the protective net 2. The cooperation between the clamping platform 112 and the clamping groove 113 can achieve rapid positioning of two adjacent connecting rods 11, facilitating installation.

[0031] Furthermore, the clamping platform 112 is provided with first through-holes extending through both sides thereof, and the two opposing side walls of the clamping slot 113 are provided with second through-holes extending through both sides of the connecting rod 11. When the clamping platform 112 and the clamping slot 113 are engaged, the first through-holes and the second through-holes intersect. The inner walls of the first through-holes and the second through-holes are both threaded. When the clamping platform 112 and the clamping slot 113 are engaged, tightening bolts can be passed sequentially through the first through-holes and the second through-holes to securely connect the two connecting rods 11, providing a strong secure connection.

[0032] In specific implementation, combined with Figure 3 The card slot 113 passes through the end of the rod body 111 away from the card platform 112. When the connecting rod 11 is not long enough and two connecting rods need to be overlapped in parallel, the card platform 112 can be directly inserted into the card slot 113 along the length direction of the rod body 111; in addition, the card slot 113 also passes through the side wall of the rod body 111. When the two connecting rods 11 are overlapped perpendicularly to each other, the card platform 112 can be inserted into the card slot 113 along the length direction perpendicular to the other connecting rod 11.

[0033] In this embodiment, the connecting rod 11 is further provided with a fixing buckle 12 that can be connected to the scaffolding. The fixing buckle 12 replaces the binding rope to enhance the stability of the connection.

[0034] As a preferred embodiment, a plurality of fixing buckles 12 on any of the connecting rods 11 are provided along the length direction of the connecting rod 11, and the fixing buckles 12 are equidistantly arranged so that the force exerted on the connecting rod 11 can be transmitted to the scaffolding more evenly, while ensuring that after a fixing buckle 12 is damaged, a stable connection effect can still be maintained between the connecting rod 11 and the scaffolding.

[0035] Specifically speaking, the structure of the fixing buckle 12 is combined with Figure 4 The fixing buckle 12 includes a main body 121 with two arc-shaped notches on one side. Locking members 122 are also provided on the outside of the two notches, respectively, to compress and secure the connecting rod 11 and the scaffolding within the two notches. Connecting the scaffolding and connecting rod 11 with the fixing members replaces the method of directly tying the scaffolding and protective net 2 with straps, enhancing overall stability. Furthermore, the two notches are designed to match the size of the scaffolding and connecting rod 11, enabling quick installation, improving installation efficiency, and allowing for reuse.

[0036] Further preferably, rubber strips are provided on the inner walls of the two notches to increase the friction coefficient between the scaffolding and the connecting rod 11 and the inner walls of the notches, thereby playing an anti-slip role.

[0037] In a specific implementation, the locking member 122 includes an arc-shaped pressure plate, one side of which is hingedly connected to the main body block 121, and the other side is provided with a bolt that can lock it with the main body block 121, and the open side of the arc-shaped pressure plate is provided with an anti-slip rubber strip.

[0038] In another embodiment, combined Figure 5 The fixing buckle 12 includes a main body block 121, and a first arc-shaped notch that can be connected to the scaffolding is provided on one side of the main body block 121, and two second arc-shaped notches that can be connected to the connecting rod 11 are provided in parallel on the other side opposite to the first notch. The outer sides of the first notch and the second notch are provided with locking parts 122 that can respectively press and fix the connecting rod 11 and the scaffolding in the notch.

[0039] When the protective net 2 of the present invention is subjected to external force, the connecting rod 11 can disperse the force borne by the protective net 2 and transmit it to the scaffolding, changing the point-like force of the original binding connection method into a linear force form. The force on the edge of the protective net 2 is more balanced. At the same time, the fixing buckle 12 replaces the rope binding method to improve the stability of the connection with the scaffolding. The connecting rod 11 is "S"-shaped and penetrates the mesh on the side of the protective net 2. The "S"-shaped penetration method realizes the movable connection between the protective net 2 and the connection. During transportation, the protective net 2 and the connecting rod 11 can be packaged and transported separately, which is convenient and fast. Moreover, the connecting rod 11 can be assembled end to end, and can adapt to protective nets 2 of different sizes and protection requirements.
