And the protection plate can be adjusted to play different buffering roles and is arranged on the open space of the unbackfilled top of the fertilizer groove. The top open space, which is not backfilled, of the fertilizer groove is provided with an adjustable protection plate with different buffering effects, and the protection plate buffers gravity impulse impact generated by falling of different objects in the top open space of the fertilizer groove without generating noise to affect the construction environment. The problem that an existing isolation plate cannot carry out buffering protection and noise reduction on gravity impulse impact generated by falling of different objects is solved.

Description

Technical Field

[0001] The utility model relates to a protective structure for falling objects in a fertilizer trough that has not been backfilled, and belongs to the technical field of building construction. Background Art

[0002] During the construction of the foundation pit and podium building, since the fertilizer trough between the underground shear wall and the foundation pit wall cannot be backfilled immediately after the basement is completed, the open space on the top of the fertilizer trough needs to be protected to prevent objects from falling and causing injuries to workers in the fertilizer trough.

[0003] The existing protection technology for the top of the fertilizer trough is shown in Chinese Patent Publication No. CN217501290U. Although the isolation board can protect the open space on the top of the fertilizer trough at different angles, the falling objects are different at different working times, and the gravity impulse impact generated by the falling objects on the isolation board will produce noise affecting the construction environment, resulting in the problem that the existing isolation board cannot buffer, protect and reduce noise for the gravity impulse impact generated by the falling of different objects. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a protection structure for falling objects in a fertilizer tank that has not been backfilled.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a protection structure for falling objects in a fertilizer tank that has not been backfilled, comprising:

[0007] The fertilizer trough is formed between the underground shear walls and the foundation pit wall space, and the top of the fertilizer trough that is not backfilled is an open space;

[0008] The protective plate can be adjusted to play different buffering roles and is installed on the open space at the top of the fertilizer tank that has not been backfilled.

[0009] One end of the protection plate is rotatably hinged on the foundation pit wall through a hinge, and the other end of the protection plate is at the top surface of the underground shear wall.

[0010] The protective plate comprises a rigid bottom plate;

[0011] A middle plate, the middle plate is fixed to the rigid bottom plate;

[0012] A rigid top plate is mounted on the middle plate through an elastic member with elastic force and a retractable telescopic rod.

[0013] The middle plate is provided with a through hole for accommodating the elastic member and the telescopic rod. The fixed end of the telescopic rod is fixed on the rigid bottom plate. The telescopic end of the telescopic rod is fixedly connected to the elastic member. The elastic member is fixedly connected to the rigid top plate. When the telescopic rod is extended, it pushes against the elastic member to lift the rigid top plate so that there is a gap between it and the middle plate but it does not contact the rigid top plate.

[0014] The telescopic rod is a telescopic rod or a pneumatic telescopic rod.

[0015] The middle part of the rigid bottom plate is supported by a telescopic support member, and the rigid bottom plate is rotatably hinged on the foundation pit wall by a hinge.

[0016] The support member is a telescopic rod or a pneumatic telescopic rod.

[0017] The beneficial effect of the utility model is that an adjustable protective plate with different buffering effects is installed in the open space at the top of the fertilizer trough that has not been backfilled. The protective plate can buffer the gravitational impulse impact caused by the fall of different objects in the open space at the top of the fertilizer trough without generating noise that affects the construction environment, thereby solving the problem that the existing isolation plates cannot buffer, protect and reduce noise for the gravitational impulse impact caused by the fall of different objects.

[0020] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0021] like Figure 1 shown.

[0022] The present application discloses a protection structure for falling objects in a fertilizer tank that has not been backfilled, comprising:

[0023] A fertilizer trough 1 is formed between the underground shear wall 11 and the foundation pit wall 12, and the top of the fertilizer trough 1 that is not backfilled is an open space.

[0024] The protective plate 2 is installed obliquely, and one end of the protective plate 2 is rotatably hinged on the foundation pit wall 12 through a hinge 3, and the other end of the protective plate 2 is at the top surface of the underground shear wall 11. The middle part of the bottom surface of the protective plate 2 is adjustable and supported by a retractable support member 4.

[0025] The protective plate 2 comprises a rigid bottom plate 21 made of a steel plate or a wooden plate, the middle part of the rigid bottom plate 21 is adjustable supported by a support member 4, and the rigid bottom plate 21 is rotatably hinged to the foundation pit wall 12 through a hinge 3;

[0026] A middle plate 22 made of a foam pad or a palm pad, the middle plate 22 is bonded or bolted to the rigid bottom plate 21;

[0027] The rigid top plate 23 is made of a steel plate or a wooden plate. The rigid top plate 23 is installed on the middle plate 22 through an elastic member 24 with elastic force formed by a spring or elastic rubber and a retractable telescopic rod 25. The middle plate 22 is provided with a through hole for accommodating the elastic member 24 and the telescopic rod 25. The fixed end of the telescopic rod 25 is fixed on the rigid bottom plate 21. The telescopic end of the telescopic rod 25 is fixedly connected to the elastic member 24, and the elastic member 24 is fixedly connected to the rigid top plate 23. When the telescopic rod 25 is extended, it pushes against the elastic member 24 to lift the rigid top plate 23 so that there is a gap between it and the middle plate 22 but it does not contact it.

[0028] The support member 4 and the telescopic rod 25 can both be formed by a hydraulic telescopic rod or a pneumatic telescopic rod.

[0029] After the rigid top plate 23 presses the elastic member 24 to contact the middle plate 22, the rigid top plate 23 no longer has a buffer distance, so the distance that the telescopic rod 25 pushes the elastic member 24 to extend out of the through hole of the middle plate 22 is a distance that ensures that the rigid top plate 23 plays a buffering role; when the telescopic rod 25 is retracted so that the telescopic rod 25 and the elastic member 24 are completely in the through hole of the middle plate 22, the rigid top plate 23 is pulled to directly contact the middle plate 22, and the rigid top plate 23 can no longer combine with the elastic member 24 to play a buffering role.

[0030] Then, by pushing the elastic member 24 out of the through hole of the middle plate 22 through the telescopic rod 25 to different distances, the rigid top plate 23 combined with the elastic member 24 can play a buffering role to different degrees, so that the protective plate 2 can be adjusted to play different buffering roles and be installed in the open space at the top of the fertilizer tank 1 that has not been backfilled.

[0031] The present application installs an adjustable protective plate 2 with different buffering functions in the unfilled top open space of the fertilizer tank 1. The protective plate 2 can buffer the gravitational impulse impact caused by the falling of different objects in the open space at the top of the fertilizer tank 1 without generating noise that affects the construction environment, thereby solving the problem that the existing isolation plates cannot buffer, protect and reduce noise for the gravitational impulse impact caused by the falling of different objects.
