[0002] In the field of construction engineering, safety protection at construction sites is of paramount importance, directly affecting the life safety of construction workers and the smooth progress of the project. Most current safety protection devices are integrated designs, which are bulky and occupy a large area, making them extremely inconvenient to transport, especially in areas with complex terrain or narrow spaces, where the difficulty of transportation is greatly increased.
[0003] Existing protective devices often use non-removable connections such as welding between components. When a component is damaged, it is extremely inconvenient to replace, which not only increases maintenance costs but may also affect the normal use of other components, thereby shortening the service life of the protective device. In addition, the protective functions of existing protective devices are limited, and most of them only have basic isolation functions. They are difficult to effectively deal with complex situations such as falling objects from heights and flying materials, and cannot provide comprehensive and reliable safety protection for the construction process.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0023] This embodiment describes a protective device for building construction, including a protective plate 4, a crossbeam 6, a protective net 9, two locking posts 5, two internal threaded sleeves 7, two support mechanisms one and two support mechanisms two;
[0024] A protective plate 4 is provided between the two support mechanisms. Two locking posts 5 are provided on the upper end of the protective plate 4. Each locking post 5 is used in conjunction with the corresponding support mechanism 2. The upper ends of the two support mechanisms are engaged with the crossbeam 6 and fixed by the corresponding internal threaded sleeve 7. The outer wall of the crossbeam 6 is provided with a placement groove. The two support mechanisms 2 are symmetrically arranged in the placement groove. A protective net 9 is provided between the two support mechanisms 2. The two ends of the protective net 9 are detachably connected to the corresponding support mechanism 2.
[0025] Each of the aforementioned support mechanisms includes a base 1, a plug rod 2, and a threaded post 3;
[0026] The base 1 has a first insertion hole, the lower end of the insertion rod 2 is inserted into the first insertion hole, the upper end of the insertion rod 2 is fixedly connected to the threaded post 3, the crossbeam 6 has a second insertion port that matches the threaded post 3, the threaded post 3 is inserted into the lower end of the second insertion port, the internal threaded sleeve 7 is slidably inserted into the upper end of the second insertion port and threadedly connected to the threaded post 3, and four sliding grooves are evenly distributed on the side wall of the insertion rod 2, each sliding groove is used in conjunction with the protective plate 4.
[0027] Each of the second support mechanisms includes a crossbar 8, a support rod 10, and a buckle 11;
[0028] The crossbar 8 is hinged to the inner wall of the placement groove on the crossbeam 6. The side wall of the crossbar 8 is detachably connected to the protective net 9. The lower end of the crossbar 8 has a second placement groove. One end of the support rod 10 is hinged to the inner wall of the second placement groove, and the other end of the support rod 10 is hinged to the buckle 11. The buckle 11 is engaged and fixed with the corresponding buckle post 5.
[0029] The building protection device also includes a connecting plate 12; the two side walls of the connecting plate 12 are respectively used in conjunction with corresponding sliding grooves.
[0030] The installation and use process of this utility model is as follows: First, place the base 1 of the two support mechanisms in a pre-set position. This pre-set position is determined according to the actual protection requirements and site conditions of the construction project. It is necessary to ensure that the base is placed stably and conforms to the overall protection layout. Next, accurately insert the lower end of the insertion rod 2 into the insertion hole 1 on the base 1, so that the insertion rod 2 is tightly connected to the base 1. Since the side wall of the insertion rod 2 is evenly distributed with four sliding grooves, and the sliding grooves of adjacent insertion rods 2 are arranged opposite each other, this provides a limiting and guiding function for the subsequent installation of the protective plate 4. After the support mechanism is installed, insert the protective plate 4 vertically downward from above. During insertion, the protective plate 4 fits tightly against the sliding grooves on both sides of the two adjacent insert rods 2. The limiting effect of the sliding grooves ensures that the protective plate 4 is stably fixed between the two support mechanisms, providing a basic protective barrier for the protective device. After the installation of the protective plate 4 is completed, the crossbeam 6 is placed above the two insert rods 2. At this time, the threaded post 3 at the upper end of each insert rod 2 needs to be accurately inserted into the corresponding insertion port 2 on the crossbeam 6. The upper end of the insert rod 2 will abut against the lower end of the crossbeam 6, providing support for the crossbeam 6. Subsequently, the internal threaded sleeve 7 is inserted from the upper end of the insertion port 2, making it threadedly connected to the threaded post 3 inside the insertion port 2. Because... The upper end of the internal threaded sleeve 7 is provided with a boss. When the internal threaded sleeve 7 is tightened with the threaded post 3, the boss will limit the upper end of the crossbeam 6, thereby firmly fixing the crossbeam 6 to the upper end of the two support mechanisms, making the upper structure of the entire protective device more stable. After the crossbeam 6 is installed, open the crossbar 8 hinged to the inner wall of the placement slot 1, and unfold the protective net 9 originally stored in the placement slot 1. The two ends of the protective net 9 are detachably connected to the side walls of the corresponding crossbar 8. This connection method facilitates the installation and replacement of the protective net 9. Next, rotate the support rod 10 in the placement slot 2 at the lower end of the crossbar 8 to make the support rod 10 a suitable angle, and then, put the support rod 10... The buckle 11, hinged at the other end, engages with the corresponding post 5 on the upper end of the protective plate 4 for fixation. This engagement ensures the protective net 9 is stably tensioned between the two support mechanisms, further enhancing the protective effect. If multiple protective devices need to be connected side-by-side or at right angles to further expand the protective range, a connecting plate 12 can be installed. The two side walls of the connecting plate 12 are inserted into the grooves of the insert rods 2 on two adjacent protective devices, ensuring a tight connection between the connecting plate 12 and the insert rods 2. The connecting plate 12 reinforces the connection between the support mechanisms, improving the overall structural strength of the protective device. Through these steps, the installation of the construction protection device is completed. This device, through the close cooperation between its components, provides effective protection for the construction site, ensuring the safety of construction workers and the surrounding environment. Disassembly is simple; the device can be easily removed and stored or transferred to other construction sites by following the reverse order of installation.
