[0039] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0040] like Figures 1 to 5 As shown, the embodiment of the utility model provides a curtain wall groove embedded device, comprising:

[0041] U-shaped steel channel 1;

[0042] The U-shaped steel channel 1 is fixed to the composite floor structure 3 by anchor bolts 2;

[0043] Ribbed steel bars 4 are evenly spaced on one side of the U-shaped steel channel 1;

[0044] The ribbed steel bars 4 are pre-embedded in the composite floor structure 3;

[0045] The first end of the platform bracket fixing member 5 is connected to the U-shaped steel channel 1 through a fixing bolt 6;

[0046] The second end of the platform bracket fixing member 5 is connected to the platform bracket member 7;

[0047] The platform bracket 7 is connected to the unit curtain wall system 9 through a T-shaped bracket 8 .

[0048] In this embodiment, the U-shaped steel channel 1 can also select channel steel of suitable specifications as needed. The closed end of the U-shaped steel channel 1 is evenly provided with multiple anchor bolts 2, and the multiple anchor bolts 2 are buried in the composite floor structure 3; the open end of the U-shaped steel channel 1 is consistent with the surface height of the composite floor structure 3, and ribbed steel bars 4 are evenly arranged among the multiple anchor bolts 2. The ribbed steel bars 4 are welded to the closed end of the U-shaped steel channel 1, and the ribbed steel bars 4 extend one end distance on both sides of the U-shaped steel channel 1 to keep the embedded parts stable. The extended length is set as needed. The distance from the ribbed steel bars 4 to the inside of the floor is 350mm to 600mm, which depends on the size of the horizontal shear force borne by the embedded parts. The minimum spacing of the ribbed steel bars 4 is 6d (d is the diameter of the steel bar) and the maximum does not exceed 300mm, which is generally 100mm. To 150mm is more appropriate. The ribbed steel bar 4 is pre-embedded in the composite floor structure 3; the first end of the platform code fixing piece 5 is connected to the U-shaped steel channel 1 through a fixing bolt 6; to facilitate the installation of the nut of the U-shaped steel channel 1, a section of the slot leg is milled off at both ends of the U-shaped steel channel. The U-shaped steel channel 1 uses a rectangular nut 20, which helps to increase the contact area between the nut and the U-shaped steel channel and improve the bearing capacity. This solution is for thin floor slabs and high-bearing capacity embedded parts. The U-shaped steel channel 1 is generally made of 40mm*40mm*5mm or 50mm*50mm*6mm steel. For embedded parts that are not subjected to much force, the commonly used trough-type embedded parts on the market can be used; the second end of the platform code fixing piece 5 is connected to the platform code piece 7; the platform code piece 7 is connected to the unit curtain wall system 9 through the T-shaped code piece 8.

[0049] The platform bracket fixing member 5 is designed to reduce eccentric load, which helps to reduce the additional load of the slot-type embedded device.

[0050] For the embedded parts supporting the unit curtain wall panels on the thin floor, wind load is the main control load and shear bearing capacity is the key point of design control. The method of welding ribbed steel bars at the bottom of the U-shaped steel channel is adopted to transfer the horizontal force to the inside of the composite floor structure through the U-shaped steel channel and ribbed steel bars, thereby improving the shear bearing capacity of the channel embedded parts.
