Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to a protective device and a protective system. Background Art

[0002] During the construction of steel structures, protective nets are typically installed inside and outside the building to prevent falling objects. Inside the building, the nets are typically hung from hooks welded to the edges of the lower flanges of two adjacent steel beams. However, these hooks are numerous, and operators must install and remove the nets one by one, resulting in low work efficiency, high operational risks, and the hooks cannot be recycled.

[0003] The prior art discloses an electric sliding safety net device with adjustable size, such as Figure 1 As shown, an eyebolt 01 is fixed at one corner of the horizontal opening. A wall connection piece 02 is installed at each of the other three corners of the horizontal opening. A steel wire rope 03 passes through the eyebolt 01 and the three wall connections 02 in sequence. Three sides of the safety net 04 are connected to the steel wire rope 03 via quick-release buckles 05. A traction rope 06 is connected to the fourth side of the safety net 04. The other end of the traction rope 06 is connected to a winch 07, which pulls the safety net 04 along the steel wire rope 03. Two rigging turnbuckles 08 are connected to the eyebolt 01. The two ends of the steel wire rope 03 are connected to the two rigging turnbuckles 08. The operator tightens the steel wire rope 03 by adjusting the rigging turnbuckles 08 to ensure that the steel wire rope 03 is taut.

[0004] In the above solution, an operator can connect the quick-release buckle 05 to the wire rope 03 and the safety net 04 on one side of the horizontal opening and use the winch 07 to pull the safety net 04. This solution is highly efficient, has minimal operational risk, and the quick-release buckle 05 can be recycled. However, the operator needs to actively check whether the wire rope 03 is taut. If the wire rope 03 is slack, the operator needs to manually adjust the rigging turnbuckle 08 to tighten the wire rope 03. This operation is inconvenient and easy to forget, resulting in poor protection. Utility Model Content

[0045] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0046] The following combination Figures 2 to 4 , describing the embodiments of the present utility model.

[0047] According to an embodiment of the present utility model, on the one hand, a protective device is provided, which is used to be arranged between two objects to be fixed 1 arranged at intervals, including: a protective net 2, which is arranged between the two objects to be fixed 1; a plurality of fixing components 3, which are fixedly connected to each object to be fixed 1 along the extension length direction of the objects to be fixed 1, and each fixing component 3 is provided with a penetration channel; a first connecting member 4, which is penetrated in the penetration channel; a second connecting member 5, which is sleeved on the outside of the first connecting member 4 and fixedly connected to the protective net 2, and the second connecting member 5 is slidably connected to the first connecting member 4, and the second connecting member 5 is provided with an avoidance channel, which is used for the second connecting member 5 to drive the protective net 2 to slide on the first connecting member 4 to avoid the fixing component 3.

[0048] By arranging a protective device between the two objects to be fixed 1, falling objects from high altitude can be prevented, and personal danger to the operator can be avoided; by arranging multiple fixing components 3 on the object to be fixed 1, and the first connecting member 4 is passed through the passing channel of the fixing component 3, multiple parts of the protective net 2 can be supported by the fixing component 3, so that the protective net 2 is in a taut state, and no operator needs to check it. The protective effect is good, and the middle position of the protective net 2 can be prevented from loosening during use, so that falling objects from high altitude fall through the gap between the protective net 2 and the object to be fixed 1; by sliding the second connecting member 5 to the first connecting member 4, the protective net 2 can be connected only at one end of the object to be fixed 1. After the connection is completed, the protective net 2 can be directly slid from one end to the other end to complete the laying of the protective net. The work efficiency is high, the operation risk is small, and the second connecting member 5 is convenient for recycling.

[0049] In this embodiment, the object to be fixed 1 is a steel beam. As a convertible embodiment, the object to be fixed 1 can also be a concrete beam or floor panel or other building structure or other structure that needs to be protected at high altitude, without making too many restrictions here.

[0050] like Figure 3As shown, along the extended length direction of the protective net 2, a plurality of fixing components 3 are evenly arranged on each steel beam; the fixing components 3 on the two steel beams are arranged relative to each other. By evenly arranging a plurality of fixing components 3 on each steel beam, the protective net 2 can be fixedly supported at each position along the length direction of the steel beam to prevent the protective net 2 from collapsing in the middle; by arranging the fixing components 3 on the two steel beams relative to each other, the connection of the protective net 2 is facilitated and the sliding is smoother. As a convertible embodiment, the fixing components 3 can also be arranged more only at the ends and middle positions of the steel beam, and less at other positions. As a convertible embodiment, the fixing components 3 can also be arranged on other sides of the steel beam, and there are no excessive restrictions here.

[0051] like Figure 4 As shown, the fixing assembly 3 in this embodiment includes: a first fixing member 31, one end of which is fixedly connected to the steel beam; a second fixing member 32, which is fixedly connected to the other end of the first fixing member 31, and the second fixing member 32 is provided with a through-channel. Specifically, the first fixing member 31 is a flat plate, one end of which is welded to the steel beam, and the other end extends horizontally, and the second fixing member 32 is arranged near the other end of the flat plate. By forming the fixing assembly 3 from the first fixing member 31 and the second fixing member 32, it is convenient to form two side surfaces with different cross-sectional dimensions, thereby facilitating the second connecting member 5 to avoid the fixing assembly 3. As a convertible embodiment, it is also possible that a sleeve member is welded to the other end of the flat plate, and the second connecting member 5 is passed through the through hole of the sleeve member. As a convertible embodiment, when the steel beam is a concrete beam, the first fixing member 31 is pre-embedded in the concrete beam.

[0052] like Figure 4 As shown, in this embodiment, the second fixing member 32 has an inverted U-shaped cross-section. The closed end of the second fixing member 32 and the first fixing member 31 together form a through-hole. Furthermore, the first fixing member 31 is provided with two through-holes, through which the two ends of the second fixing member 32 extend. The fixing assembly 3 includes a fastener 33, which is used to securely connect the first fixing member 31 and the second fixing member 32. The second fixing member 32 is provided with external threads, and the fastener 33 is a nut. By forming a through-hole with the closed end of the second fixing member 32, which has an inverted U-shaped cross-section, and the first fixing member 31, the structure is simple and easy to operate. By inserting the two ends of the second fixing member 32 into the through-holes of the first fixing member 31 to form a fixed connection, the second fixing member 32 can be recycled. As an alternative embodiment, the cross-section of the second fixing member 32 can also be circular or semicircular, as long as it can form a through-hole, and there are no further restrictions here. As a convertible embodiment, the two end portions of the second fixing member 32 may be welded to the first fixing member 31 , and no further restrictions are imposed here.

[0053] In this embodiment, the first connecting member 4 is a steel wire rope. As a convertible embodiment, the first connecting member 4 can also be a steel strand or other connection structure, which is not limited here.

[0054] like Figure 3 As shown, in this embodiment, there are multiple second connecting members 5. By providing multiple second connecting members 5, the connection strength of the protection net 2 can be improved to prevent the protection net 2 from being loose and affecting the protection effect.

[0055] like Figure 4 As shown, the cross-section of the second connecting member 5 in this embodiment is "C"-shaped, and the "C"-shaped opening forms an avoidance channel. Along the extending length direction perpendicular to the steel beam, the dimension a of the opening is greater than the dimension b of the first fixing member 31, and smaller than the cross-sectional dimension c of the first connecting member 4. Here, the dimension a of the opening is the height between the two opposite walls of the opening, the dimension b of the first fixing member 31 is the thickness of the first fixing member 31, and the cross-sectional dimension c of the first connecting member 4 is circular. By setting the cross-sectional shape of the second connecting member 5 to "C", it is convenient to connect with the first connecting member 4 and the protective net 2, and the opening is convenient to avoid the fixing component 3 so that the second connecting member 5 can slide on the first connecting member 4; by setting the size of the opening to be larger than the size of the first fixing member 31 and smaller than the cross-sectional dimension of the first connecting member 4, the second connecting member 5 can avoid the fixing component 3 when sliding on the first connecting member 4 and will not fall off the first connecting member 4.

[0056] like Figure 2 As shown, in this embodiment, a traction member is fixedly connected to the end of the protective net 2 perpendicular to its extended length. The traction member is used to pull the protective net 2 to slide on the first connecting member 4. The traction member is a steel wire rope. The provision of the traction member facilitates rapid deployment of the protective net 2. As an alternative embodiment, the traction member can also be provided in the extended length direction of the protective net.

[0057] According to an embodiment of the present invention, on the other hand, a protection system is provided, comprising: two steel beams, which are spaced apart; and the above-mentioned protection device, which is arranged between the two steel beams.

[0058] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
