DETAILED DESCRIPTION

[0015] The technical scheme of the utility model will be more clearly and completely described below by the description of the preferred embodiment of the utility model in combination with the drawings.

[0016] As Figure 1As shown, the preferred embodiment of the fireproof connection structure for the interlayer node of the glass curtain wall of this utility model includes a concrete wall 1, a column 2 on the outer side of the concrete wall 1, an upper horizontal beam 3 above the side of the column 2, an upper glass sub-frame 31 on the side of the upper horizontal beam 3 away from the concrete wall 1, a first insulated glass above the upper glass sub-frame 31, a lower horizontal beam 4 below the side of the column 2, a lower glass sub-frame 41 on the side of the lower horizontal beam 4 away from the concrete wall 1, a second insulated glass 52 between the lower glass sub-frame 41 and the upper glass sub-frame 31, and a third insulated glass 53 at the bottom of the lower glass sub-frame 41. The upper horizontal beam 3 and the lower horizontal beam 4 are stainless steel beams.

[0017] like Figure 2 As shown, flame-retardant and fireproof strips 71 are provided between the upper crossbeam 3 and the upper glass sub-frame 31, and between the lower crossbeam 4 and the lower glass sub-frame 41, respectively. Steel fireproof pressure plates 72 are provided on the outer side of the upper glass sub-frame 31 and the outer side of the lower glass sub-frame 41, respectively. An aluminum alloy outer cover 73 is provided on the outer side of the steel fireproof pressure plate 72.

[0018] like Figure 1 As shown, a first stainless steel plate 32 is connected below the upper beam 3. The first stainless steel plate 32 is L-shaped. A floor is provided at the top of the concrete wall 1. The L-shaped end of the first stainless steel plate 32 extends to the bottom of the floor. An upwardly inclined first mounting plate 33 is provided at the end of the first stainless steel plate 32. A first fireproof adhesive part 34 is provided between the first mounting plate 33 and the top of the concrete wall 1. When smoke and fire between the first mounting plate 33 and the floor reach the top of the column 2, the first fireproof adhesive part 34 expands due to heat, sealing the gap between the first mounting plate 33 and the floor, thereby isolating the smoke and fire below the upper beam 3 and preventing the smoke and fire from easily rising to the upper floor.

[0019] like Figure 1 As shown, a second stainless steel plate 42 is provided on the inner side of the lower crossbeam 4. The head of the second stainless steel plate 42 is parallel to the floor level, the middle part of the second stainless steel plate 42 is perpendicular to the floor level, and the tail of the second stainless steel plate 42 is parallel to the floor level. The tail of the second stainless steel plate 42 is located at the bottom of the concrete wall 1. A downwardly inclined second mounting plate 43 is provided at the tail of the second stainless steel plate 42. A second fireproof adhesive part 44 is provided between the second mounting plate 43 and the bottom of the concrete wall 1. The gap between the second mounting plate 43 and the floor level is sealed by the second fireproof adhesive part 44. Thus, when the galvanized steel frame suppresses the smoke and fire, some of the smoke and fire will enter the gap between the second mounting plate 43 and the floor level. At this time, the second fireproof adhesive part 44 expands due to heat and seals this gap, making it difficult for the smoke and fire to spread upward through the gap. This also prevents the temperature between the outside of the floor level and the double-glazed glass from rising rapidly. On the one hand, it can protect the double-glazed glass; on the other hand, it can extend the function of the first fireproof adhesive part 34 at the upper crossbeam 3.

[0020] As shown in Figure 1 The lower part of the upper cross beam 3 and the upper part of the lower cross beam 4 are respectively provided with a first galvanized steel frame 61, and the first galvanized steel frame 61 is filled with fireproof cotton 63. A second galvanized steel frame 62 is arranged between the column 2 and the concrete wall 1, the second galvanized steel frame 62 is located between the two first galvanized steel frames 61, and the second galvanized steel frame 62 is filled with fireproof cotton 63. The filled fireproof cotton 63 is a non-combustible material, so when the fire spreads to the galvanized steel frame from the next floor, the fireproof cotton 63 is not easy to be burned by the fire, thereby suppressing the fire below the galvanized steel frame, avoiding the spread of the fire through the floor of the area upwards, providing more escape space and escape time for people, and meanwhile, the structure of the whole glass curtain wall interlayer joint is not easy to be damaged.

[0021] The glass curtain wall concave-convex interlayer joint fireproof connecting structure can delay the spread speed of the fire, and is beneficial to improve the fireproof effect of the glass curtain wall.

[0022] The above specific embodiments only describe the preferred embodiments of the utility model, and do not limit the protection scope of the utility model. Without departing from the design concept and spirit category of the utility model, various deformations, substitutions and improvements of the technical scheme of the utility model made by the ordinary skilled in the art according to the description and drawings of the utility model should belong to the protection category of the utility model. The protection scope of the utility model is determined by the claims.
