[0041] The utility model will be described in further detail below in combination with the drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0042] It should be noted that if the utility model embodiments involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain posture (as shown in the drawings). If the certain posture changes, the directional indications also change accordingly.

In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that the ordinary skilled in the art can realize it. When the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0044] Please refer to Figures 1-5 A glass-steel grating double-layer curtain wall connecting structure without beam column:

[0045] It comprises an inner layer column 1 and a steel grating 2 located in the outer layer, and a plurality of inner and outer curtain wall connecting pieces 3. The inner layer column 1 serves as the supporting structure of the inner layer curtain wall and bears a certain load; the steel grating 2 constitutes the outer layer curtain wall, and the beam column structure is directly connected with the inner glass curtain wall, having the functions of beauty and protection.

[0046] The U-shaped connecting piece 31 is installed on the outer side column surface of the inner layer stand column 1 through the first positioning bolt 311 arranged on both sides thereof. The U-shaped connecting piece 31 is designed in a shape that can tightly fit the outer side column surface of the inner layer stand column 1, and the first positioning bolt 311 can firmly fix the U-shaped connecting piece 31 on the inner layer stand column 1, thereby ensuring the stability of the connection and providing a solid foundation for the subsequent connection work.

[0047] The cantilever arm 321 is connected to the front end surface of the U-shaped connecting piece 31 by welding. The cantilever arm 321 is an important component of the connecting structure, and the tenon socket 322 arranged at the front end thereof is a rectangular cavity inside, and the front end and the top are not closed, serving as a plug-in port for the tenon plug 342. This design enables the cantilever arm 321 to provide support while facilitating connection with the front end connecting piece 34.

[0048] The front end connecting piece 34 is a connecting arm 341, and the tenon plug 342 is arranged at one end of the inner side of the connecting arm 341 and is matched with the tenon socket 322. The tenon plug 342 of the connecting arm 341 can be accurately inserted into the tenon socket 322 at the front end of the cantilever arm 321, thereby realizing the tight connection of the two.

[0049] The tenon plug 342 arranged at the front end of the connecting arm 341 is inserted into the tenon socket 322 at the front end of the cantilever arm 321, and then the tenon end of the cantilever arm 321 and the connecting arm 341 is fixed by two second positioning bolts 323. Such a connection mode not only can ensure the firmness of the connection, but also can withstand external forces on the curtain wall to some extent, thereby improving the overall stability of the curtain wall.

[0050] The front end of the connecting arm 341 is connected to the inner side surface of the steel grating 2 by welding. Through this connection mode, the inner layer stand column 1 and the steel grating 2 are effectively connected together, so that the double-layer curtain wall forms a whole. The steel grating 2 as the outer layer curtain wall not only can play a decorative role, but also can provide a certain protection function to protect the inner layer curtain wall from the influence of external factors.

[0051] The reinforcing angle steel 33 is arranged at the bottom of the connecting end of the U-shaped connecting piece 31 and the cantilever arm 321. The arrangement of the reinforcing angle steel 33 can further enhance the stability of the connecting structure, improve the bearing capacity of the connecting part, effectively prevent the connecting part from being deformed or damaged when subjected to external forces, thereby ensuring the safety and reliability of the connecting structure of the double-layer curtain wall.
