Description

Technical Field

[0001] This utility model relates to the field of protective netting technology, specifically protective netting for construction projects. Background Technology

[0002] In construction engineering, safety nets are an important building facility. Multiple safety net devices are typically used on construction sites to enclose the site, thereby enhancing safety during construction.

[0003] Currently, the general structure of existing construction safety nets is as follows: a metal mesh is fixed to the inside of a square frame, ear plates are fixed to both horizontal sides of the square frame, and a mounting base is fixed to the bottom. In use, anchor bolts are used to fix the mounting base to the construction site, thus completing the installation and fixing of a single safety net. Then, multiple bolts and nuts are used to splice adjacent safety nets together.

[0004] It is easy to see that the existing protective nets are quite cumbersome to install, requiring the tightening of many bolts and nuts, which is inefficient; moreover, the existing protective nets are generally fixed structures and are large in size, making them inconvenient to store and transport. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a protective net for construction projects, which can be easily spliced ​​and installed when in use, and can be easily stored and transported when not in use.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] The protective netting for construction projects includes a winding box, a winding mechanism, a protective netting body, and a base. The winding box is open on the left side and has a base installed at the bottom. One side of the protective netting body is connected to a hook, and the other end is connected to the winding mechanism installed inside the winding box. The netting body is wound into the winding box by the winding mechanism. The right side of the winding box is provided with hanging rings that correspond one-to-one with the hooks.

[0008] As an improvement, the winding mechanism includes a winding tube, a handwheel, and a rotary positioning structure. The winding tube is rotatably connected between the upper and lower side walls of the winding box, and its top end extends to the outside of the winding box, where the handwheel is fixed. The rotated winding tube is fixed by the rotary positioning structure, and the protective netting is connected to and wound onto the winding tube. The protective netting can be easily wound up for storage or unwound for use.

[0009] As an improvement, the rotary positioning structure includes a fixed end face gear plate, a movable end face gear plate, and a knob nut. The fixed end face gear plate and the movable end face gear plate mesh with each other, and each has a through hole pre-drilled in its middle portion for the winding drum to pass through. The fixed end face gear plate is fixed to the top surface of the winding box, and the upper side of the movable end face gear plate abuts against a knob nut threaded onto the winding drum. This allows the winding drum to be fixed in place after the protective netting has been fully wound or partially unwound.

[0010] As an improvement, it also includes a threaded drill rod and a second handwheel; the base is generally inverted T-shaped, and each end is integrally formed with a threaded sleeve. The threaded drill rod is threaded into the threaded sleeve, and after passing through the pre-drilled hole on the base, the conical head at the bottom is inserted into the ground, and the second handwheel is fixed at the top. This allows for convenient and stable installation and fixing of this new invention onto the ground of a construction site.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] 1. When using this new type of equipment, the hooks on the protective net and the rings on the winding box can be used to easily splice two adjacent pieces of this new type of equipment together; they can also be easily disassembled.

[0013] 2. When not in use, this new type of protective netting can be rolled up as much as possible into the winding mechanism inside the winding box, thus reducing its space occupation and making it easier to store, load, and transport. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Safety netting for construction projects includes:

[0022] The winding box 1, base 3, threaded drill rod 11 and handwheel 2 12 are all included. The winding box 1 is open on the left side. The base 3 is in the shape of an inverted T. Threaded sleeves 13 are integrally formed at both ends. Threaded drill rod 11 is threaded into threaded sleeves 13. After passing through the pre-drilled hole on the base 3, the conical head at the bottom is inserted into the ground. Handwheel 2 12 is fixed at the top.

[0023] The winding mechanism and the protective net body 2 are as follows: The protective net body 2 is made of steel wire mesh and has a hook 4 connected to one side. The right side of the winding box 1 is provided with a hanging ring 5 corresponding to the hook 4. Three hooks 4 and three hanging rings 5 ​​are evenly arranged vertically. The winding mechanism includes a winding tube 6, a handwheel 7, a fixed end face toothed disc 8, a movable end face toothed disc 9, and a knob nut 10. The winding tube 6 is rotatably connected between the upper and lower side walls of the winding box 1, and the top end extends to the outside of the winding box 1 and is fixed with a handwheel 7. The fixed end face toothed disc 8 and the movable end face toothed disc 9 are engaged with each other, and each has a through hole for the winding tube 6 to pass through. The fixed end face toothed disc 8 is fixed on the top surface of the winding box 1, and the upper side of the movable end face toothed disc 9 is abutted against a knob nut 10 threaded onto the winding tube 6.

[0024] In the specific implementation of this embodiment:

[0025] After placing two adjacent "construction safety nets" side by side on the construction site ground, pull the safety net body 2 to completely unroll it, and hook the hook 4 on it to the hanging ring 5 on the winding box 1 of the adjacent "construction safety net". In this way, the two adjacent "construction safety nets" can be spliced ​​together. Then, rotate the threaded drill rod 11 clockwise until it drills as deep into the ground as possible, and the installation of a single "construction safety net" is completed.

[0026] It is worth mentioning that multiple "construction engineering protective nets" can be spliced ​​together to form a temporary protective wall. In order to make the length of the protective wall more accurate, the protective net body at the end of the protective wall can be unrolled in two parts.

[0027] It is easy to understand that after partially unwinding or rewinding the protective netting 2, tightening the knob nut 10 will allow the fixed end face gear 8 and the movable end face gear 9 to mesh securely together. This will fix the winding drum 6 in place.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
