Description

Technical Field

[0001] This utility model relates to the field of protection technology, specifically to a protective device for building demolition operations. Background Technology

[0002] Demolition projects refer to the demolition of existing or partially completed buildings or structures. Based on the extent of demolition, they are divided into complete demolition and partial demolition. With the acceleration of urban modernization in my country, the number of old building demolition projects is increasing. The structures of the demolished objects have also evolved from brick-and-wood structures to mixed structures, frame structures, and slab structures, and from house demolition to the demolition of chimneys, water towers, bridges, docks, and other buildings or structures.

[0003] Most existing protective devices consist of multiple interconnected metal plates fixed to the ground, forming a protective ring around the building. During demolition, it is inevitable that stones will fly. When these stones hit the metal plates, the impact force acts directly on the metal plates because the plates lack cushioning. This not only causes dents on the surface of the metal plates, but also, since the ground around the demolished building is usually uneven, the metal plates are not securely fixed to the ground. Under the impact of stones, the metal plates may wobble, resulting in poor stability. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem this invention aims to solve is that the metal plate lacks cushioning, which may cause it to sway and become unstable under the impact of stones.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a protective device for building demolition operations, including two fixed rods arranged on opposite sides, a metal plate between the fixed rods, a fixed column on the fixed rods, a fixed rod movably inserted into the fixed column, a spring sleeved on the fixed column between the fixed rod and the fixed rod, a fixing mechanism for limiting the fixed rod at one end of the fixed column, an elastic net between the fixed rods, and a stabilizing mechanism on the bottom surface of the fixed rod.

[0008] As an improvement, the fixing mechanism includes a threaded groove on the fixing column, a stud threadedly connected to the threaded groove, and a limiting plate at one end of the stud for limiting the second fixing rod.

[0009] As an improvement, the stabilizing mechanism includes a plug rod that is movably inserted into the bottom surface of a fixed rod, and a crossbar is provided on the bottom surface of the plug rod, on which a soil nail is movably inserted.

[0010] As an improvement, the insertion rod is provided with multiple slots, and a pin that mates with the slots is movably inserted into the first fixing rod. One end of the pin is provided with a limiting post, and a tension spring sleeved on the pin is provided between the limiting post and the first fixing rod.

[0011] As an improvement, the crossbar is provided with a groove, and the soil nail is located in the groove.

[0012] (III) Beneficial Effects

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] By setting up a fixed rod, springs, and an elastic net, when stones are thrown, they will fall onto the elastic net, preventing them from hitting the metal plate and causing damage. At the same time, the springs can weaken the kinetic energy of the stones, increasing the weight of the stones intercepted by the elastic net. The fixed mechanism can keep the metal plate fixed, and by increasing the contact area with the ground, the stability can be improved, making the whole structure less prone to shaking.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] As per the instructions Figures 1 to 3As shown, a protective device for building demolition operations includes two fixed rods 1 arranged on opposite sides, a metal plate 2 between the fixed rods 1, a fixed post 3 on the fixed rods 1, a second fixed rod 4 movably inserted into the fixed post 3, a spring 5 sleeved on the fixed post 3 between the second fixed rod 4 and the fixed rod 1, a fixing mechanism 6 for limiting the second fixed rod 4 at one end of the fixed post 3, an elastic net 7 between the second fixed rods 4, and a stabilizing mechanism 8 on the bottom surface of the fixed rods 1.

[0022] As per the instructions Figures 2 to 4 As shown, the fixing mechanism 6 includes a threaded groove 9 on the fixing post 3, and a stud 10 is threadedly connected to the threaded groove 9. One end of the stud 10 is provided with a limiting plate 11 that limits the fixing rod 4. By setting the detachable limiting plate 11, it is convenient to remove the fixing rod 4 and the elastic net 7.

[0023] The stabilizing mechanism 8 includes a plug rod 12 that is movably inserted into the bottom surface of the fixing rod 1. A crossbar 13 is provided on the bottom surface of the plug rod 12. A soil nail 15 is movably inserted into the crossbar 13. A groove 14 is provided on the crossbar 13. The soil nail 15 is located in the groove 14. By setting the groove 14, the soil nail 15 is located below the surface of the crossbar 13, which does not affect the installation of the fixing rod 4.

[0024] The insertion rod 12 is provided with multiple slots 16, and the fixing rod 1 is movably inserted with a pin 17 that cooperates with the slots 16. One end of the pin 17 is provided with a limiting pin 18, and a tension spring 19 is sleeved on the pin 17 between the limiting pin 18 and the fixing rod 1.

[0025] In practical use, first place the fixing rod 1 on the ground, then fix the fixing rod 1 with the soil nail 15, then install the fixing rod 2 4 and the elastic net 7 on the front side of the fixing rod 1 through the fixing post 3, then align the stud 10 with the threaded groove 9 and tighten it. At this time, one end of the spring 5 abuts against the fixing rod 2 4. When it is necessary to adjust the height of the fixing rod 1, push the limiting post 18 outward, the tension spring 19 is stretched, and the insertion post 17 moves away from the slot 16. Then lift or push the fixing rod 1 upward. When the appropriate height is reached, release the limiting post 18, the tension spring 19 pulls the insertion post 17, so that the insertion post 17 enters the slot 16, and the height adjustment of the metal plate 2 is completed.
