DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0023] Combination Figure 1 A fireproof structure of a plug-in steel keel curtain wall includes a base plate 1, a support plate 3 is snap-connected to the upper end of the base plate 1, two groups of support plates 3 are fixedly connected, and a fireproof plate A5 is snap-connected between the two groups of support plates 3.

[0024] The utility model is further described below in conjunction with embodiments.

[0025] Embodiment 1:

[0026] See also Figure 1-Figure 5 A threaded hole 21 is provided on one side of one group of support plates 3, a screw rod 2 is threadedly connected inside the threaded hole 21, a chamber 25 is provided inside the screw 2, an air hole 23 is provided on one side of the screw 2, a rotating shaft 26 is fixedly connected inside the screw 2, a fan blade 24 is fixedly connected to one side of the rotating shaft 26, and a handle 22 is fixedly connected to the other side of the rotating shaft 26, and a rotating hole 32 is provided on one side of the other group of support plates 3, and the screw rod 2 is rotatably connected to the other group of support plates 3 through the rotating hole 32.

[0027] Specifically, the clamping width is adjusted according to curtain walls of different sizes, and the handle 22 is turned to make the rotating shaft 26 rotate accordingly. At this time, the screw 2 also rotates. Since the screw 2 and the other set of support plates 3 are rotatably connected, the other set of support plates 3 are moved left and right to adjust the clamping width. When the rotating shaft 26 rotates, the fan blades 24 also rotate, and wind blows from the air holes 23 onto the fireproof board A5, which can dry the fireproof board A5 in a humid environment and reduce the adverse effects of moisture on the fireproof material.

[0028] Embodiment 2:

[0029] See also Figure 1-Figure 4 A mounting groove 11 is provided at the upper end of the base plate 1, and a fireproof cotton strip 13 is fixedly connected inside the mounting groove 11. A snap-fit ​​groove A31 is provided on the inner sides of the two groups of support plates 3. The moisture-proof board 4 and the fireproof board B8 are snap-fitted inside the snap-fit ​​groove A31. A snap-fit ​​groove B12 is provided on the upper surface of the base plate 1, and one group of support plates 3 is snap-fitted with the base plate 1 through the snap-fit ​​groove B12. A spring A7 is fixedly connected to one side of the mounting groove 11, and a block 33 is fixedly connected to one side of one group of support plates 3. The block 33 is fixedly connected with two groups. A snap plate 71 is fixedly connected to one side of the spring A7, and the snap plate 71 is snap-fitted between the two groups of blocks 33. A spring B6 is fixedly connected to the inner wall of the mounting groove 11, and the other end of the spring B6 is fixedly connected to one group of support plates 3.

[0030] Specifically, the fixed connection of the fireproof cotton strip 13 can play a fireproof role. When replacement is needed, it is only necessary to turn the handle 22 to drive the screw 2 to rotate, so that one group of support plates 3 is away from the other group of support plates 3, and the fireproof cotton strip 13 can be taken out from the installation groove 11, which is very convenient for replacement. The fireproof board B8 can prevent fire above the curtain wall. In winter, the warm air conditioner will make the relatively warm air in the room rise, and the relatively cold air will sink, which may cause moisture to move upward along the warm air. The moisture-proof board 4 is fixedly connected at the top to prevent the influence of the curtain wall in a humid environment. The spring B6 is in a compressed state, and the elastic force generated by the compression provides support force for the connected support plates 3, and the clamping of the curtain wall is more secure. During the movement of one group of support plates 3, the card plate 71 is squeezed, so that the spring A7 is compressed, so that the card plate 71 and the card block 33 are out of the engaged connection state, and when the support plate 3 contacts the surface of the curtain wall, the squeezing of the spring A7 is retracted, so that the card plate 71 is engaged and connected between the two groups of card blocks 33 for fixation.
