Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of building protection equipment, and in particular relates to a foldable protective net frame for buildings. Background Technology
[0002] Traditional building safety netting often uses fixed metal frame structures, which have problems such as large size, heavy weight, time-consuming disassembly and assembly, and large space occupation for transportation and storage, making it difficult to meet the needs of temporary or mobile construction operations. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model provides a foldable protective net frame for construction, which can be quickly folded and stored, achieving convenient transportation and efficient deployment.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a foldable protective net frame for construction, comprising columns, crossbars, and a protective net body installed on the columns. Multiple parallel crossbars are provided between every two columns. Each crossbar includes a first rotating rod hinged to one column, a second rotating rod hinged to the other column, and an anti-rotation component. The first and second rotating rods are hinged together, and can rotate upwards synchronously. When the first and second rotating rods are parallel and have a synchronous downward rotation tendency, the anti-rotation component can prevent the first and second rotating rods from rotating downwards synchronously. Both the first and second rotating rods have pre-set anchor holes for connection and fixation.
[0005] Preferably, the anti-rotation component is a baffle plate disposed on the first rotating rod. The baffle plate is located at the connection between the first rotating rod and the second rotating rod, and is located above the second rotating rod. When the first rotating rod and the second rotating rod are parallel, the second rotating rod will press against the anti-rotation component.
[0006] Preferably, the bottom of the first rotating rod is provided with a clearance groove, the width of the second rotating rod is not greater than the width of the clearance groove, and the second rotating rod can at least partially fit into the clearance groove.
[0007] Preferably, the crossbar is provided with a shaping rod, and each crossbar on both sides of the column is provided with a shaping hole. The two ends of the shaping rod are provided with inserts, which can be inserted into the shaping holes of the crossbars on both sides of the corresponding column, forming a triangular structure with the two crossbars.
[0008] Preferably, the crossbar is provided with a shaping rod, and each crossbar on both sides of the column is provided with a shaping hole. One end of the shaping rod is rotatably connected to the shaping hole of the crossbar on one side of the column, and the other end is provided with a plug, which is inserted into the shaping hole of the crossbar on the other side of the column, forming a triangular structure with the two crossbars.
[0009] Preferably, multiple parallel protective strips are provided between adjacent columns. The protective strips are non-rigid strips, and their height is not less than the height of the protective netting.
[0010] Preferably, the protective strip is a nylon rope covered with an elastic sleeve.
[0011] Preferably, the column is provided with a connecting ring for connecting to the protective net body, and the connecting ring is inclined downward in the direction pointing to the center of the protective net body.
[0012] The technical effects of this utility model are as follows: The hinged design of the first and second rotating rods and the anti-rotation blocking mechanism enable the crossbar to be quickly folded and unfolded and locked, significantly improving the efficiency of disassembly and assembly, while ensuring the structural stability after unfolding.
[0013] The triangular structure formed by the shaped rods and crossbars effectively enhances the overall load-bearing capacity and deformation resistance of the frame, improving the strength and reliability of the protective mesh frame.
[0014] The non-rigid protective strip combined with the elastic sleeve design provides effective protection while reducing the risk of collision, thus better ensuring the protective effect. Attached Figure Description

[0021] The present invention will be further described below with reference to specific embodiments and accompanying drawings.
[0022] like Figures 1-5As shown, a foldable protective net frame for construction includes columns 1, crossbars 2, and a protective net body 3. There are four columns 1 arranged in a square pattern. Two parallel crossbars 2 are arranged between adjacent columns 1. The protective net body 3 is installed on the columns 1 and is located within the enclosure of the columns 1 and crossbars 2. The protective net body 3 has two layers spaced apart from top to bottom.
[0023] Furthermore, each column 1 has a connecting ring 4 on the side wall facing the protective net body 3. The connecting ring 4 is inclined downward along the direction pointing towards the center of the protective net body 3 to preset the direction of force exerted on the column 1 when the protective net body 3 is subjected to force. A reinforcing rib is provided between the connecting ring 4 and the column 1. The reinforcing rib is located below the connecting ring 4 and is fixedly connected to the connecting ring 4 and the column 1 respectively.
[0024] Furthermore, each crossbar 2 includes a first rotating rod 21 and a second rotating rod 22. One end of the first rotating rod 21 is hinged to a column 1 on one side, and the other end is hinged to the second rotating rod 22. One end of the second rotating rod 22 is hinged to a column 1 on the other side, and the other end is hinged to the first rotating rod. The top of the end of the first rotating rod 21 facing the second rotating rod 22 is provided with an anti-rotation member 5. The anti-rotation member 5 is a baffle structure, which is located above the first rotating rod 21 and extends a portion of its length above the second rotating rod 22. Its bottom can interfere with and abut against the top of the second rotating rod 22.
[0025] Furthermore, the bottom of the first rotating rod 21 is provided with a clearance groove 6, and the width of the second rotating rod 22 is smaller than the groove width of the clearance groove 6. When the first rotating rod 21 and the second rotating rod 22 rotate towards each other, part of the second rotating rod 22 can be inserted into the clearance groove 6 to further reduce the volume after folding.
[0026] Furthermore, the crossbars 2 on both sides of each column 1 are connected and fixed by a shaping rod 7. The anti-rotation member 5 on the crossbars 2 on both sides of the column 1 has a shaping hole at its top. In some embodiments, the shaping rod has a post 8 at both ends. The post 8 at both ends of the shaping rod can be inserted into the corresponding shaping hole to form a triangular stable structure with the two crossbars 2. In other embodiments, one end of the shaping rod 7 is rotatably connected to the shaping hole of the crossbar 2 on one side of the column 1, and the other end has a post 8. The post 8 is inserted into the shaping hole of the crossbar 2 on the other side of the column 1 to form a triangular stable structure with the two crossbars 2.
[0027] Furthermore, multiple parallel protective strips 9 are provided between adjacent posts 1. The protective strips 9 are non-rigid strips, and their height is higher than that of the protective net body 3. Both ends are connected and fixed to the posts to further improve the protective effect. The protective strips 9 are nylon ropes covered with rubber sleeves; they can also be rubber strips with a certain degree of elasticity.
[0028] Furthermore, both the first and second rotating rods are pre-drilled with anchor bolt holes to facilitate the quick fixing of the protective net frame with anchor bolts.
[0029] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. The present utility model can be used in similar products. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
