Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and particularly relates to a protective net for construction engineering. Background Technique

[0002] With the continuous development of social economy and the continuous improvement of construction level, various buildings have sprung up across the country. The emergence of various buildings has greatly improved people's living quality. However, in building construction, in order to prevent high-altitude falling stones, etc., it is usually necessary to set up a protective net outside the building or by the roadside to prevent building materials from falling and injuring pedestrians.

[0003] Many of the existing protective nets for construction engineering are temporary and are installed by simple bolts and nuts. This simple method is prone to looseness, which may lead to the inclination or collapse of the protective net. Moreover, it is very inconvenient and time-consuming to assemble and disassemble. At the same time, during the construction process, due to different construction environments, the effective length of the protective net needs to be adjusted during the construction of the protective net, and the versatility of the existing protective nets is not strong.

Detailed implementation mode

[0016] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0017] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0018] Embodiment 1, as shown in Figure 1 、 Figure 2 shown, a protective net for construction engineering of the present application includes a first base 1 and a second base 2; the first base 1 is arranged on the left side of the second base; on the top surface of the first base 1, a first column 3 and a housing 4 are fixedly installed in sequence from right to left; on the second base 2, a winch 5 and a second column 6 are fixedly installed in sequence from right to left; the front cross-sections of the first column 3 and the second column 6 are T-shaped, and first driven rollers 7 are fixedly installed at the left and right ends of the tops of the first column 3 and the second column 6; the outer surface of the winch 5 is surrounded by the main body of the protective net 8, and the other end of the main body of the protective net 8 passes through the first driven roller 701 on the right side of the second column, the first driven roller 702 on the left side of the second column, the first driven roller 703 on the right side of the first column, and the first driven roller 704 on the left side of the first column in sequence, passes through the top surface of the housing 4 and is fixedly wound around the outer surface of the second driven roller 9; the second driven roller 9 is fixedly installed inside the housing 4 through a first support column 10 whose other end is fixedly connected to the bottom surface of the inner wall of the housing 4;

[0019] The first base 1 and the second base 2 are detachably arranged on the ground; during use, the effective area of the protective net body 8 required is calculated according to the environment of the construction site, and the effective area of the protective net body 8 is changed by changing the relative distance between the first base 1 and the second base 2, so that the protective net for construction projects of the present application can be applied to various scenarios and has strong versatility; during storage, the protective net body 8 is wound on the outer side of the second driven roller 9, and the protective net body 8 is drawn to the winch 5 by starting the motor on the back of the winch 5 to realize the unfolding of the protective net body 8. Pedestrians can walk under the protective net body 8 between the first base 1 and the second base 2, and the protective net body 8 intercepts the building materials falling from a height.

[0020] The inner side of one end of the protective net body 8 close to the winch 5 is fixedly connected to the top end of a canvas 11. The canvas 11 is in contact with the inner side of the protective net body 8. The width of the front and rear ends of the canvas 11 is the same as that of the protective net body 8. The inner side of the canvas 11 away from the end connected to the protective net body 8 passes through the first driven roller 701 on the right side of the second column, the first driven roller 702 on the left side of the second column, the first driven roller 703 on the right side of the first column, and the first driven roller 704 on the left side of the first column in sequence and then passes through the top surface of the housing 4 and is fixedly wound on the outer side of the fourth driven roller 12; the fourth driven roller 12 is fixedly installed inside the housing 4 by a second support column 13 whose other end is fixedly connected to the bottom surface of the inner wall of the housing 4; thus, a canvas 11 is arranged below the protective net body 8 between the first base 1 and the second base 2, which can effectively intercept gravel or sand and gravel smaller than the mesh opening of the protective net body 8 and prevent pedestrians' clothes from being soiled.

[0021] At the entrance of the protective net body 8 and the canvas 11 into the housing 4 at the top inside the housing 4, there are also two third driven rollers 14, namely the left third driven roller 1401 and the right third driven roller 1402; the left third driven roller 1401 is in contact with the outer side of the protective net body 8, and the right third driven roller 1402 is in contact with the inner side of the canvas; the inner side of the protective net body 8 between the left third driven roller 1401 and the right third driven roller 1402 is in close contact with the outer side of the canvas 11; since the canvas 11 is soft, it is easy to fold during the winding or extraction process, which is likely to affect the effective area of the canvas 11. The setting of the third driven roller 14 flattens the canvas 11 and clamps the canvas 11 and the protective net body 8 during the subsequent movement, so that the canvas 11 and the protective net body 8 will not shift during the extraction process, affecting the ability to intercept the falling building materials.

[0022] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
