Description

Technical Field

[0001] The utility model belongs to the technical field of building construction equipment, and in particular relates to a falling prevention device for building construction. Background Art

[0002] High-altitude work refers to work performed by people above a certain height reference plane. According to the national standard GB / T 3608-2008 "Classification of High-altitude Work", this includes five basic types of high-altitude work, such as edge, opening, climbing, hanging, and crossing. In the construction industry, the scope of high-altitude work involved is wide, including but not limited to operations on shelves above 2m in buildings, scaffolding, derricks, gantries, construction elevators, and high-altitude work formed when various lifting machinery and equipment are in use.

[0003] The main safety risk of working at height is falling, which can cause serious injury or even death. There are many types of falls, such as falling from edges, falling from holes, falling from scaffolds, and falling from suspended heights. These types of falls are usually related to factors such as lack of proper protective measures, careless operation, and equipment failure.

[0004] In the prior art, in addition to strengthening personal protective equipment, the main means of preventing high-altitude falls is to set up safety nets in areas where high-altitude falling objects may occur to prevent objects from falling and injuring people. However, the existing safety nets are difficult to set up on the one hand, and the structure is not stable enough on the other hand. When subjected to pressure, the safety nets are easily detached due to excessive instantaneous pressure. Utility Model Content

[0005] The purpose of the utility model is to provide a falling prevention device for building construction, which is more stable and reliable by changing the connection structure of the falling prevention device, and can be flexibly installed and erected according to specific construction needs.

[0026] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0027] like Figure 1-Figure 3As shown, a falling prevention device for building construction comprises a plurality of columns 1, a plurality of joints 2 respectively arranged at different heights of each column 1, and a safety net 8 is connected between adjacent joints 2; the joints 2 comprise a mounting base plate arranged in the column 1, and fixing bolts 5 passing through the mounting base plate and the column 1 and connected to the joints 2; a plurality of butt joints 7 are arranged at the edge of the safety net 8, and the butt joints 7 are respectively inserted into the joints 2 and fastened by connecting screws.

[0028] Compared with the prior art, in the prior art, the anti-fall device mainly adopts the form of a safety net 8, which is made of chemical fiber as the main material, and is required to have a small specific gravity, high strength, good wear resistance, large elongation and strong durability. At the same time, it should also have certain weather resistance, and its strength will not decrease too much after being damp. Commonly used materials include synthetic chemical fibers such as vinylon and nylon. The safety net 8 is generally composed of a net body, side ropes, tethers and tendon ropes. The net body is woven by net ropes and has a diamond or square mesh. The side ropes are net ropes on the edges of the net body, which are used to determine the size of the safety net 8. The tethers are used to fix the safety net 8 on the support. On the one hand, the hanging method adopted by this safety net 8 requires a lot of manual operation to be carried out, and each tether is tied to the scaffolding, and it is necessary to perform reverse operation here in the later recovery process, which wastes a lot of manpower. On the other hand, the structure is not stable enough through the hanging method, and the gravity that each tie point can withstand varies according to the different hanging methods of the workers. In the present invention, the hanging method of the safety net 8 is modified to directly insert the butt-joint pipe 7 into the joint 2 and fix it with screws, so that the structure is simpler and the installation and recovery operations are convenient.

[0029] The top and bottom of the joint 2 are both provided with connection threaded holes 6. Multiple butt joints 7 are respectively inserted into different joints 2 at the same height, and the safety net 8 is spread out. The joint 2 is provided with a connection internal thread, and the end of the butt joint 7 is provided with a connection thread head. After the butt joint 7 is inserted into the joint 2, the connection screws are inserted into the butt joint 7 through the upper and lower connection threaded holes 6 of the joint 2, and the screws are tightened to achieve rapid installation of the safety net 8.

[0030] A support reinforcement rib 3 is provided between the upper and lower joints 2 at different heights. The joints 2 are connected to both sides of the column 1, and a triangular support plate 4 is provided between the column 1 and the joint 2. The bearing capacity of the safety net 8 is increased by the support reinforcement rib 3 and the triangular support plate 4.

[0031] In specific use, the utility model has a variety of usage modes:

[0032] Implementation Method 1

[0033] A scaffolding system is adopted, and the multiple columns 1 provided by the utility model are respectively connected to the scaffolding system for fixing, and the joints 2 set on both sides of the columns 1 are respectively exposed as connecting parts. After the columns 1 are built, the net hanging operation can be carried out, and the columns 1 provided by the utility model are provided with joints 2 at different heights. According to the specific environmental requirements of the site, the safety net 8 can be set at different heights, or multiple layers of safety nets 8 can be set. When hanging the net, it is only necessary to use the butt joints 7 to insert them into different positions respectively, use the thread to rotate the butt joints 7 into the joints 2, and then use screws to strengthen and tighten them to avoid problems such as the pipe falling off after being subjected to gravity. Different butt joints 7 are inserted into different joints 2 at the same height to fully open the safety net 8. When recycling, simply remove the screws and other components, and pull out the butt joints 7, avoiding problems such as knotting and entanglement of the tether in the later stage.

[0034] Implementation Method 2

[0035] The utility model can also be used alone. When used alone, a base needs to be set at the bottom of the column 1 to support the ground to prevent the column 1 from tilting. When setting the base, a base with a counterweight needs to be used. After the column 1 is installed on the base, the net hanging operation is performed again. Similarly, by inserting the butt pipe 7 into the joint 2 and tightening and locking it, different butt pipes 7 are inserted into different joints 2 at the same height, so that the safety net 8 is fully opened.

[0036] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
