Description

Technical Field

[0001] This utility model relates to the field of building construction protection technology, and more specifically, to a safety protection device for building construction. Background Technology

[0002] Currently, dense-mesh safety nets and horizontal safety nets are widely used in construction as the main safety protection facilities against falling objects. They are made of high-strength polyethylene or nylon, with a mesh density of no less than 800 meshes / 100cm / , which can intercept small falling objects (such as screws and gravel). However, safety nets still need to be installed and fixed with the help of support frames and connecting components. For example, the patent with announcement number CN221722368U discloses a safety net for falling objects in safety engineering. It fixes the net body with an installation frame, and further uses ropes and hooks to fix the installation frame to achieve on-site installation of the net body. However, because the safety net is made of high-strength polyethylene or nylon, it has both elasticity and toughness. However, using an installation frame to fix the edge of the net body, there is a safety hazard that the net body may slip during the support process after a falling object. In addition, in order to facilitate the replacement of the net body, multiple installation frames are used for installation, which will increase the self-weight of the protective device, and thus increase the burden on the ropes, hooks and other connecting devices.

[0003] Based on the above description, there is an urgent need for a safety protection device for building construction that is highly stable and not prone to slippage. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection device for construction, which aims to solve the technical problem that existing safety nets used in construction, which use installation frames to fix the net body, are prone to slipping off the edges when catching falling objects.

[0005] The embodiments of this utility model are achieved through the following technical solutions:

[0006] A safety protection device for construction includes multiple nets and a pair of connecting components; the multiple nets are stacked; the pair of connecting components are respectively located at both ends of the multiple nets; the connecting components are connected to the nets through multiple hook components; each layer of the net has multiple connecting holes; the connecting holes of the multiple layers of the net correspond to each other; each hook component passes through the connecting holes of the multiple layers of the net simultaneously.

[0007] Preferably, the connecting component is a perforated strip plate; the hook assembly includes a first hook body; one end of the first hook body is connected to the perforated strip plate; and multiple layers of netting are sequentially hooked onto the other end of the first hook body.

[0008] Preferably, the connecting component is a U-shaped groove; the hook assembly includes a first hook and a second hook; the first hook and the second hook are arranged opposite to each other; the connecting parts of the first hook and the second hook are both embedded in the groove cavity of the U-shaped groove and connected to the U-shaped groove.

[0009] Preferably, the hooking portion of the first hook is arranged opposite to the hooking portion of the second hook; the multiple layers of net are all hooked between the hooking portions of the first hook and the hooking portions of the second hook.

[0010] Preferably, the hooking part of the first hook is an arc-shaped plate; the hooking part of the second hook is a semi-circular plate; the end of the semi-circular plate away from the U-shaped groove extends into and is embedded in the interior of the arc-shaped plate through the notch.

[0011] Preferably, the arc-shaped plate includes a first side and a second side; the first side extends toward the U-shaped groove; the second side is recessed and provided with a limiting groove; the end of the semi-circular plate of the first side away from the U-shaped groove extends into the limiting groove from the notch of the arc-shaped plate.

[0012] Preferably, the first side portion is provided with radially extending ear blocks; the ear blocks are provided with multiple through holes for the rope to pass through.

[0013] Preferably, the end of the connecting component away from the hook component is provided with multiple lifting lugs.

[0014] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0015] This invention employs a hook-and-hook assembly to allow for the simultaneous stacking and hooking of multiple nets, forming a stable support structure and extending service life.

[0016] Secondly, each layer of netting has multiple connection holes at its end. Then, in the same vertical direction, the hook assembly passes through the corresponding connection holes of each layer of netting in sequence, thereby achieving the hooking of the netting and the connection of the connection assembly.

[0017] Secondly, by using connecting components to install multiple hook components at equal intervals, the uniformity of force on the net body is ensured after the hook components hook onto the net body, thereby improving the stability of the connection at the end of the net body. This fully guarantees the stability of the net body when receiving falling objects and avoids the safety hazards caused by the easy slippage of the connection at the end of the net body.

[0022] The specific implementation method is described below with reference to the accompanying drawings.

[0023] Example 1

[0024] Please see Figures 1 to 3 This utility model provides the following technical solution: a safety protection device for building construction, which is applicable to situations where there is a risk of falling objects from heights during building construction.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, a safety protection device for construction includes multiple nets 1 and a pair of connecting components 2; the multiple nets 1 are stacked; the pair of connecting components 2 are respectively located at both ends of the multi-layer nets 1; the connecting components 2 are connected to the nets 1 through multiple hook components 3; each layer of nets 1 is provided with multiple connecting holes; the connecting holes of the multi-layer nets 1 correspond to each other; each hook component 3 passes through the connecting holes of the multi-layer nets 1 simultaneously.

[0026] In this embodiment, hook components 3 are used to simultaneously hook multiple nets 1, forming a stable support structure and extending service life. Each layer of net 1 has multiple connection holes at its end. In the same vertical direction, hook components 3 pass through the corresponding connection holes of each layer of net 1 in sequence, thereby hooking the net 3 and connecting it to the connecting components 2. Furthermore, by using connecting components 2 to install multiple hook components 3 at equal intervals, the uniformity of force on the net 1 is ensured after the hook components 3 hook the net 1, thereby improving the stability of the connection at the end of the net 1 and fully ensuring the stability of the net 1 when receiving falling objects, thus avoiding the safety hazard of the connection at the end of the net 1 easily slipping.

[0027] In this embodiment, the connecting holes on the mesh body 1 can be the mesh holes of the mesh body 1 itself. To further ensure the stability of the connection, a pair of ring pads can be set on the mesh holes. The pair of ring pads are connected to the two sides of the mesh body 1 respectively, and the hook assembly 3 passes through the opening in the middle of the ring pad. The ring pads are made of hard and corrosion-resistant plastic, alloy or other materials. The pair of ring pads can be fixedly connected by bonding, welding or other methods depending on the specific material.

[0028] Specifically, such as Figure 1 As shown, the connecting component 2 is a strip-shaped perforated plate; the hook component 3 includes a first hook body 31; one end of the first hook body 31 is connected to the strip-shaped perforated plate; and the other end of the first hook body 31 is sequentially hooked with multiple layers of net body 1.

[0029] In this embodiment, the connecting component 2 can be a strip-shaped perforated plate, and the hook component 3 can be only a first hook 31. The hook part of the first hook 31 can be a U-shaped hook, or a bent hook with a central angle greater than 270°, to prevent the net body 1 from falling out of the sleeve opening. The connecting part of the first hook 31 is a connecting perforated plate, and the connecting hole block and the strip-shaped perforated plate are screwed together by bolts. The strip-shaped perforated plate is provided with multiple screw holes at intervals to facilitate the flexible installation of multiple first hooks 31, which can be used to adapt to the connection requirements of different net bodies 1 and ensure the stability of the net body 1 after connection.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, the connecting component 2 is a U-shaped groove; the hook assembly 3 includes a first hook 31 and a second hook 32; the first hook 31 and the second hook 32 are arranged opposite to each other; the connecting parts of the first hook 31 and the second hook 32 are both embedded in the groove cavity of the U-shaped groove and connected to the U-shaped groove. The hooking parts of the first hook 31 and the hooking parts of the second hook 32 are arranged opposite to each other; the multi-layer net 1 is hooked between the hooking parts of the first hook 31 and the hooking parts of the second hook 32.

[0031] In this embodiment, the connecting component 2 can preferably be a U-shaped groove; the hook component 3 preferably uses a first hook 31 and a second hook 32, so that it can not only achieve stable hooking of the multi-layer mesh 1, but also be stably embedded in the U-shaped groove, and be positioned and connected by bolts, which is more stable than using only a strip perforated plate; furthermore, the U-shaped groove is also provided with multiple screw holes at intervals, so as to flexibly install the hook component 3 according to the mesh size of the mesh 1.

[0032] Specifically, such as Figure 3 As shown, the hooking part of the first hook 31 is an arc-shaped plate 311; the hooking part of the second hook 32 is a semi-circular plate 321; the end of the semi-circular plate 321 away from the U-shaped groove extends into and is embedded in the interior of the arc-shaped plate 311 through the notch. The arc-shaped plate 311 includes a first side and a second side; the first side extends into the U-shaped groove; the second side is recessed and provided with a limiting groove 3111; the end of the semi-circular plate 321 on the first side away from the U-shaped groove extends into and is embedded in the limiting groove 3111 through the notch of the arc-shaped plate 311.

[0033] In this embodiment, the central angle of the arc-shaped plate 311 is greater than 270°, which facilitates both the pre-hooking of the multi-layer mesh 1 and the setting of the limiting groove 3111 for limiting the installation of the second hook 32 for closure.

[0034] Specifically, such as Figure 1 and Figure 3 As shown, a radially extending ear block 4 is provided on the outer side of the first side; the ear block 4 has multiple through holes for the rope to pass through.

[0035] In this embodiment, each first hook 31 is provided with an ear block 4, and a pair of connecting components 2 are provided with multiple ear blocks 4, so as to facilitate the cross-shaped installation of reinforcing ropes at the bottom layer of the net body 1 or at the bottom of each layer of the net body 1; the two ends of the reinforcing ropes are respectively connected to the ear blocks 4 provided on the pair of connecting components 2. Specifically, the ends of the reinforcing ropes pass through the holes of the ear blocks 4 and are knotted to prevent them from falling off.

[0036] Specifically, such as Figure 1 and Figure 3 As shown, the end of the connecting component 2 away from the hook component 3 is provided with multiple lifting lugs 21.

[0037] In this embodiment, the lifting lug 21 is provided with a through hole, and multiple lifting lugs 21 facilitate the installation of the protective device at the construction site by combining high-strength steel ropes and the like.
