[0001] The utility model relates to the technical field of protection sheds, in particular to a protection shed for building construction. Background Art

[0002] During the construction of high-rise buildings, in order to prevent pedestrians from being hit by falling objects, protective sheds are often built on pedestrian walkways to prevent workers from being injured. Currently, most construction protective sheds are built with scaffolding. Although local materials are used and the cost is low, the protective sheds built with scaffolding lack the necessary buffer. In actual use, there are the following problems:

[0003] Due to the lack of buffering, if a person falls and directly hits the protective shed, it will cause great harm to the workers. It cannot absorb a certain amount of impact force and reduce personal injury. Moreover, falling objects from high altitudes without buffering can easily cause a large impact on the structure of the protective shed, affecting its reliability. Utility Model Content

[0007] Preferably, any of the above schemes has a plurality of spring positioning plates fixedly connected to the top surface of the fixed plate at positions corresponding to the plurality of telescopic dampers, a buffer spring is fixedly connected to the center of the top surfaces of the plurality of spring positioning plates, and the tops of the plurality of buffer springs are pressed against the center of the bottom surface of the ceiling.

[0008] The technical effect achieved by adopting the above solution is: absorbing the impact force through the buffer spring, thereby further absorbing the kinetic energy.

[0022] Embodiment 1: Figures 1 to 3 As shown, a construction protection shed includes a top plate 1, four corners of the bottom surface of the top plate 1 are fixedly connected with support legs 2, a fixing plate 3 is fixedly connected at the center of the top surface of the top plate 1, a plurality of telescopic dampers 5 are fixedly connected to the middle parts of the two side surfaces of the fixing plate 3, the telescopic ends of the plurality of telescopic dampers 5 on both sides of the fixing plate 3 are respectively and commonly fixedly connected with a connecting shaft 6, the outer walls of the two connecting shafts 6 are rotatably connected with a plurality of connecting sleeves 7, the middle parts of the outer walls of the plurality of connecting sleeves 7 are fixedly connected with connecting columns 8, the plurality of connecting columns 8 on both sides are fixedly connected with a ceiling 4 at one end away from the connecting sleeves 7, the ceiling 4 is made of elastic steel plate, the ceiling 4 is a left-right symmetrical pointed roof structure, and the plurality of connecting columns 8 on both sides of the bottom surface of the ceiling 4 are symmetrically arranged with the pointed roof ridge of the ceiling 4 as the center line.

[0023] As an optional technical solution of the utility model, a plurality of spring positioning plates 10 are fixedly connected to the top surface of the fixed plate 3 at positions corresponding to the plurality of telescopic dampers 5, and a buffer spring 11 is fixedly connected to the center of the top surfaces of the plurality of spring positioning plates 10. The tops of the plurality of buffer springs 11 are pressed tightly against the center of the bottom surface of the ceiling 4. When the middle part of the ceiling 4 is impacted and pressed downward, the impact force is absorbed by the buffer springs 11, thereby further absorbing kinetic energy.

[0024] As an optional technical solution of the utility model, the connecting sleeve 7 is located at the center between the connecting shaft 6 and the connection between the plurality of telescopic dampers 5. The plurality of telescopic dampers 5 are in a retracted state under normal conditions, thereby preventing the connecting sleeve 7 from interfering with the telescopic damper 5. The retracted state allows the telescopic damper 5 to retain the maximum damping sliding space.

[0025] As an optional technical solution of the present utility model, the bottoms of several telescopic dampers 5 are fixedly connected with support ribs 9, the bottom surfaces of the support ribs 9 are fixedly connected to the top surface of the top plate 1, and the outer shells of several telescopic dampers 5 are completely within the range of the top surface of the top plate 1, so that the bottoms of the telescopic dampers 5 are completely supported, reducing the vertical stress they are subjected to.

[0026] As an optional technical solution of the present invention, the size of the ceiling 4 is larger than the size of the top surface of the top plate 1, and a buffer pad is fixedly connected to the top surface of the ceiling 4, so that the ceiling 4 can completely cover the top plate 1, and the buffer pad can reduce the damage to the top surface of the ceiling 4 caused by falling objects.

[0027] A construction protection shed, the working principle is as follows:

[0028] 1) When a falling object hits the ceiling 4, the inclined roof structure of the ceiling 4 can make the falling object slide down and weaken the impact force;

[0029] 2) The elasticity of the ceiling 4 itself can also absorb part of the kinetic energy. Then the ceiling 4 is compressed, and the edges on both sides extend toward the outer wall, thereby pulling the telescopic damper 5 to extend. The kinetic energy is absorbed by the damping sliding of the telescopic damper 5, thereby reducing the impact force.

[0030] 3) After the middle part of the roof 4 is pressed down by the impact, the impact force is absorbed by the buffer spring 11, thereby further absorbing the kinetic energy.

[0031] To sum up, in the construction protection shed, when falling objects hit the ceiling 4, the inclined roof structure of the ceiling 4 itself can make the falling objects slide down and weaken the impact force. At the same time, the elasticity of the ceiling 4 itself can also absorb part of the kinetic energy. Then the ceiling 4 is compressed, and the edges on both sides extend toward the outer wall, thereby pulling the telescopic damper 5 to extend. The kinetic energy is absorbed by the damping sliding of the telescopic damper 5, and the impact force is reduced, thereby greatly improving the buffering effect, improving the overall reliability, and reducing the damage to the falling workers.
