Description

Technical Field

[0001] This utility model relates to the field of concrete impact buffering technology, and in particular to a buffering device for reducing concrete impact. Background Technology

[0002] Currently, the commonly known method of concrete pouring is using flexible hoses. Concrete is transported to the construction site using equipment such as concrete placing booms, truck-mounted concrete pumps, and ground pumps. However, improper operation during concrete pouring can cause damage to the underlying building materials due to the impact of the concrete, affecting the quality of the project.

[0003] To avoid damage to the building materials of the next layer caused by existing pouring methods, this utility model provides a buffer device that can reduce the impact force of concrete pouring, reduce the damage of concrete to the building materials of the next layer, and thus improve the construction quality. Utility Model Content

[0004] The purpose of this invention is to provide a buffer device that reduces the impact force of concrete. It can make initial contact with the falling concrete through a steel plate, thereby reducing the impact force of the concrete falling directly and thus achieving buffering.

[0005] This utility model is implemented as follows:

[0006] A buffer device for reducing the impact force of concrete includes a steel plate. Two retaining rings and rotating nuts are fixedly connected around the upper end of the steel plate. The retaining rings and rotating nuts are arranged symmetrically. A steel column is arranged at the symmetrical position of the retaining rings and rotating nuts. The inner side of the rotating nut is rotatably connected to one end of the steel column through a rotating shaft. Two retaining rings are arranged on the top of the steel plate. The outer surface of the retaining rings is fixedly connected to two adjacent steel columns.

[0007] The outer sides of the two adjacent ends of the retaining ring are fixedly connected with retaining ring fixing nuts, and bolts are provided on the two adjacent sides of the retaining ring. The inner side of the retaining ring fixing nut is threadedly connected to the surface of the bolt.

[0008] The side of the retaining ring and rotating nut that are close to each other is in contact with the steel column, and the contact surface between the retaining ring and rotating nut and the steel column is set to be smooth.

[0009] The retaining ring is made of stainless steel, and the inner side of the retaining ring is roughened.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] This utility model, through the cooperation of structures such as steel plates, retaining rings, rotating nuts, and steel columns, allows the concrete pouring hose to make initial contact with the steel plate during concrete pouring, thereby buffering the impact of the concrete on the underlying building materials and improving construction quality. At the same time, the structure is simple and easy to install. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Please see the appendix Figure 1 and attached Figure 2 A buffer device for reducing the impact force of concrete includes a steel plate 2. Two retaining rings and rotating nuts 1 are fixedly connected around the upper end of the steel plate 2 and are symmetrical to each other. A steel column 3 is set at the symmetrical position of the retaining rings and rotating nuts 1. The inner side of the rotating nut 1 is rotatably connected to one end of the steel column 3 through a rotating shaft. Two retaining rings 4 are set on the upper part of the steel plate 2 and are symmetrical to each other. The outer surface of the retaining ring 4 is fixedly connected to the two adjacent steel columns 3.

[0017] Preferably, due to the large impact force of concrete, in order to ensure the durability of the device, steel plate 2 is made of 5mm thick steel plate.

[0018] By setting up the cooperation between the steel plate 2, the retaining ring rotating nut 1 and the steel column 3, the retaining ring 4 is fixedly installed on the pouring end of the concrete pouring hose, thereby indirectly fixing the steel plate 2. When the concrete hose is pouring concrete, the concrete will make its first contact with the steel plate when it falls, thus buffering the impact of the concrete on the underlying building materials and improving the construction quality.

[0019] Please see the appendix Figure 1 and attached Figure 2 The outer sides of the two close ends of the retaining ring 4 are fixedly connected with retaining ring fixing nuts 5, and bolts are provided on the two close sides of the retaining ring 4. The inner side of the retaining ring fixing nuts 5 is threadedly connected to the surface of the bolts.

[0020] By setting the bolt and the retaining nut 5 to be threaded together, the distance between the retaining nut 5 can be adjusted by rotating the bolt, so that the retaining nut 4 can be adapted to concrete pouring hoses of different diameters, which is convenient for installation and disassembly.

[0021] Please see the appendix Figure 1 and attached Figure 2 The side of the retaining ring rotating nut 1 that is close to each other contacts the steel column 3, and the contact surface between the retaining ring rotating nut 1 and the steel column 3 is set to be smooth.

[0022] By setting the contact surface between the retaining ring rotating nut 1 and the steel column 3 to be smooth, the friction is reduced, making the steel column 3 more stable when rotating inside the retaining ring rotating nut 1.

[0023] Please see the appendix Figure 1 and attached Figure 2 The retaining ring 4 is made of stainless steel, and the inner side of the retaining ring 4 is roughened.

[0024] By using stainless steel for the retaining ring 4, the problem of corrosion caused by long-term contact with water is reduced, thus significantly extending its service life. By making the inner side of the retaining ring 4 rough, the friction is increased when the retaining ring 4 contacts the output end surface of the concrete hose, making the retaining ring 4 more stable when installed on the concrete hose.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
