Description

Technical Field

[0001] The utility model relates to the field of aluminum honeycomb waterproof floors, and specifically to a novel aluminum honeycomb waterproof floor structure for rail transit trains. Background Art

[0002] At present, the development of rail transit vehicle equipment technology has advanced by leaps and bounds. Flame retardancy, lightweight, low noise, energy conservation and environmental protection have become the trends in the development of rail transit vehicle interiors; at the same time, these are also the requirements and goals put forward by rail transit services for vehicle interiors in the new era. Therefore, there is a huge demand for new materials and structures that meet the above requirements and have better decorative performance, both in terms of variety and quantity. Among them, lightweight metal materials, polymer materials, composite materials, aluminum honeycomb materials, etc. have occupied an increasingly important position in rail transit vehicle interior materials.

[0003] During the splicing process of aluminum honeycomb waterproof floors, since there is an easy occurrence of gaps between two sets of floors during splicing, although the floors themselves have waterproof functions, there are certain gaps at the splicing joints of the two sets of floors. If water enters the floors and stays for a long time, the floors will deteriorate, become moldy and smelly, resulting in damage and deformation of the floors, reducing the waterproofness of the floors and being prone to damage the sides of the floors. For this reason, new technical solutions need to be designed to solve the problem. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a novel aluminum honeycomb waterproof floor structure for rail transit trains, so as to solve the technical problem that there are certain gaps at the splicing joints of the current two sets of floors. If water enters the floors and stays for a long time, the floors will deteriorate, become moldy and smelly, resulting in damage and deformation of the floors, reducing the waterproofness of the floors and being prone to damage the sides of the floors.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a novel aluminum honeycomb waterproof floor structure for rail transit trains, including a plate body. First connection grooves are opened on both sides at the two ends of the plate body, and second connection grooves are opened on both sides at the other two ends of the plate body. First threaded holes are opened on the plate body below the four second connection grooves, and the four first threaded holes are respectively communicated with the four first connection grooves. Second threaded holes are opened on the plate body above the four first connection grooves, and the four second threaded holes are respectively communicated with the four second connection grooves. First fixing bolts and second fixing bolts are respectively threadedly connected in the four first threaded holes and the four second threaded holes.

[0006] Preferably, sealing gaskets are fixedly connected to the peripheries of the plate body, and the sealing gaskets are elastic.

[0007] Preferably, gaskets are provided at one end of the four first connecting grooves close to the first threaded holes and one end of the four second connecting grooves close to the second threaded holes.

[0008] Preferably, the lengths of the first fixing bolts and the second fixing bolts are respectively smaller than the inner lengths of the first connecting grooves and the second connecting grooves.

[0009] Preferably, the first connecting grooves and the second connecting grooves are arranged in a staggered manner, and the second connecting grooves are located above the first connecting grooves.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. Through the combination of structures such as the plate body, the first connecting groove, the second connecting groove, the first fixing bolt, the second fixing bolt, the first threaded hole, the second threaded hole and the sealing gasket, when the plate bodies are spliced with each other, the first fixing bolt or the second fixing bolt is screwed to connect with the first threaded hole and the second threaded hole on another plate body, so that the plate bodies can be quickly and tightly spliced. And during the splicing process, the elastic sealing gasket is used to increase the sealing performance between adjacent plate bodies, thereby improving the sealing effect between adjacent plate bodies, and avoiding the occurrence of gaps when adjacent plate bodies are spliced, resulting in poor waterproof performance and damage to the plate bodies.

[0012] 2. Through the setting of the gaskets, not only can the brightness inside the first connecting groove and the second connecting groove be increased, but also the looseness of the first fixing bolt and the second fixing bolt during the splicing of the plate bodies can be avoided, which affects the firmness of the splicing of the main body.

Sealing gaskets 11 are fixedly connected to the periphery of the plate body 1, and the sealing gaskets 11 are elastic. During operation, when the plate bodies 1 are spliced with each other, the first fixing bolts 22 or the second fixing bolts 32 are screwed to be connected with the first threaded holes 21 and the second threaded holes 31 on another plate body 1, so that the plate bodies 1 can be quickly and tightly spliced.

[0021] Furthermore, refer to Figure 2 and Figure 4 , the lengths of the first fixing bolts 22 and the second fixing bolts 32 are respectively smaller than the inner lengths of the first connection grooves 2 and the second connection grooves 3, which is convenient for disassembling the first fixing bolts 22 and the second fixing bolts 32 from the first connection grooves 2 and the second connection grooves 3 respectively.
