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

[0002] Safety nets are used to prevent workers or objects from falling from heights, and to avoid or reduce casualties from falling or injuries from falling objects. They are overall protective equipment for workers and work surfaces at heights. In order to facilitate storage and reuse, safety nets will be disassembled from the main frame of each scaffolding after the construction is completed. Since the safety net is tied to the main frame with ropes or wires, frequent installation and disassembly can easily cause damage to the binding parts. Therefore, damage and looseness at the connection position will not play an effective protective role. Utility Model Content

[0024] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] In the embodiment of the utility model, Figure 1-Figure 3 The foldable construction safety net comprises a first support frame 1, a second support frame 2, a safety net body 3 and a memory metal segment 4; the first support frame 1 and the second support frame 2 are arranged opposite to each other, and a bending notch is constructed therebetween; the safety net body 3 connects the first support frame 1 and the second support frame 2; the memory metal segment 4 is arranged in the bending notch, and the memory metal segment 4 has a memory state of being a straight line in a natural state, so that the first support frame 1 and the second support frame 2 are located in the same plane, and the safety net body 3 is unfolded.

[0027] Specifically, in the embodiment of the utility model, the first support frame 1 and the second support frame 2 are arranged at relative intervals to constitute the support frame body, thereby improving the overall stability; the four sides of the safety net body 3 are respectively fixed to the inner walls of the first support frame 1 and the second support frame 2 to form a complete safety net system that can be directly spliced ​​or installed for use.

[0028] In the embodiment of the utility model, since a bending notch is formed between the first support frame 1 and the second support frame 2 (the number of the bending notches is limited by the structure of the above-mentioned two support frames, and no further description is given here), in order to facilitate the storage of the safety net, a memory metal segment 4 is provided at the bending notch, which is used to connect the first support frame 1 and the second support frame 2 to form a complete frame structure to improve the overall stability, and on the other hand, since the memory metal segment 4 has a memory state that is linear along the left and right directions in a natural state, the first support frame 1 and the second support frame 2 can be arranged along the left and right directions, and then the safety net body 3 can be in an unfolded state to play a protective role; conversely, when it is necessary to store, the first support frame 1 and the second support frame 2 are overlapped, so that the memory metal segment 4 is arranged in an arc shape, and since the safety net body 3 has a certain degree of softness, it can be folded together with the above-mentioned support frame, and it is convenient for transportation and storage after storage; since the safety net body 3 is folded and unfolded together with the support frame, the two are relatively fixed, so there is no need to frequently install and disassemble the safety net body 3, which reduces the breakage rate of the two joints and improves the reuse rate of the safety net body 3.

[0029] Of course, in other embodiments, in order to further reduce the footprint of the folded safety net body 3, a plurality of bending notches may be provided in the first support frame 1 and / or the second support frame 2 for installing the memory metal segments 4 so that the safety net body 3 can be folded in a Z shape.

[0030] The utility model improves the overall stability of the safety net body 3 by using two support frames, and the connection does not need to be disassembled, thereby reducing damage to the safety net body 3; at the same time, the first support frame 1 and the second support frame 2 are connected by a memory metal segment 4, so that the two support frames can be folded relative to each other for easy storage and transportation.

[0031] like Figure 2 , Figure 3 As shown, in one embodiment, the memory metal segment 4 includes a mounting block 401 and a memory metal wire 402 embedded in the mounting block 401. The mounting block 401 is arranged at the bending notch and is used to connect the first support frame 1 and the second support frame 2. Specifically, in order to enable the memory metal segment 4 to connect the first support frame 1 and the second support frame 2 and have a memory state, the present embodiment divides the memory metal segment 4 into a mounting block 401 and a memory metal wire 402. The mounting block 401 is made of a flexible material and is installed at the bending notch to connect the first support frame 1 and the second support frame 2. Of course, the safety net body 3 near the bending notch can also be connected to the surface of the mounting block 401 to avoid a gap between the safety net body 3 and the two support frames when unfolded. The memory metal wire 402 is used to improve the structural strength of the mounting block 401 and enable the two to be arranged in a straight line in a natural state.

[0032] like Figure 2 , Figure 3 As shown, in one embodiment, the memory wire 402 is in a U-shaped structure, and its open end faces the second support frame 2 to form the memory state. Specifically, in order to enable the memory wire 402 to form two states of a straight line and an arc, the memory wire 402 is embedded in the mounting block 401 in a U-shaped structure, and its open end faces the second support frame 2. In other embodiments, the open end of the memory wire 402 can also face the first support frame 1, depending on the installation requirements.

[0033] Further, if Figure 2 As shown, in one embodiment, a through hole is provided at one end of the second support frame 2 close to the bending notch, and the open end of the memory wire 402 extends into the through hole. Specifically, in order to improve the stability of the memory wire 402, this embodiment prevents the memory wire 402 from detaching from the mounting block 401 by extending the open end of the memory wire 402 into the through hole (not shown) of the second support frame 2.

[0034] Preferably, the mounting block 401 is formed with a U-shaped mounting groove 403 , and the memory metal wire 402 is adaptively arranged in the mounting groove 403 , so as to limit the memory metal wire 402 in the mounting block 401 .

[0035] Preferably, an adhesive layer is provided between the memory metal wire 402 and the mounting groove 403 to firmly fix the memory metal wire 402 in the mounting block 401 .

[0036] like Figure 1 As shown, in one embodiment, the proximal ends of the first support frame 1 and the second support frame 2 are open structures, and the distal ends of the two are closed structures. Specifically, in order to make the safety net body 3 flat in the unfolded state, this embodiment defines the structure of the two support frames, that is, the proximal ends of the two are open structures, which are used to make the safety net body 3 seamlessly transition from one support frame to the other support frame, and also facilitate the folding of the two support frames; at the same time, the distal ends of the two are closed structures, which are used to connect and fix the edges of the safety net body 3. On the other hand, the bending notch is set at the proximal ends of the two to avoid installation interference between the memory metal segment 4 and the safety net body 3.

[0037] like Figure 1 As shown, in one embodiment, the first support frame 1 is provided with a countersunk hole 5, and the second support frame 2 is provided with a protrusion 6 matched with the countersunk hole 5, so as to limit or release the relative movement of the first support frame 1 and the second support frame 2. Specifically, in the storage state, in order to avoid a large angle between the two support frames, thereby increasing the occupied area, the present embodiment provides matching countersunk holes 5 and protrusions 6 at corresponding positions of the two support frames, so that in the storage state, the protrusions 6 are embedded in the countersunk holes 5, ensuring that the two support frames always remain in an overlapping state; on the contrary, in the unfolded state, the protrusions 6 are separated from the countersunk holes 5, and the two support frames are located in the same plane under the action of the memory wire 402.

[0038] like Figure 1 As shown, in one embodiment, the first support frame 1 and the second support frame 2 are provided with a plurality of hanging holes 7. Specifically, in order to install the first support frame 1 and the second support frame 2 at corresponding positions, or to splice two by two, in this embodiment, the hanging holes 7 are provided on the two support frames, so that the two support frames can be spread apart by external hanging parts, and the memory metal wire 402 is prevented from being bent due to accidental touching.

[0039] like Figure 1 As shown, in one embodiment, the first support frame 1 and the second support frame 2 are provided with a plurality of support ribs 8 for supporting the safety net body 3 to improve the overall structural strength.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
