Description

Technical Field

[0001] The utility model belongs to the technical field of building structures, and particularly relates to an installation structure of a galvanized plate for sealing between curtain wall floors. Background Technique

[0002] Since the curtain wall is hung on the exterior wall of the building, the gaps between the vertical keels lead to each floor. To play roles such as sound insulation and fire prevention, a fireproof layer such as mineral wool should be inlaid in the gaps between the floors to seal between the floors.

[0003] At present, the fireproof layer is usually supported by a galvanized plate. However, during the fixing process of the galvanized plate, it is usually fixed to the horizontal keel with screws, and in order to ensure the stability of the fixing structure, a large number of screws are provided, which results in a large number of screw holes on the horizontal keel, and the structural strength of the horizontal keel itself is damaged, affecting the building quality. Content of the Utility Model

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides an installation structure of a galvanized plate for sealing between curtain wall floors. By adding a support bracket to support the galvanized plate, the galvanized plate does not need to be fixed to the horizontal keel with screws, greatly reducing the number of screw holes on the keel frame, reducing the damage to the keel frame structure, and ensuring the building quality.

[0005] The specific technical solution adopted by the utility model is as follows:

[0006] An installation structure of a galvanized plate for sealing between curtain wall floors includes a floor slab, a galvanized plate and a keel frame respectively fixedly connected to the floor slab. The curtain wall is fixedly connected to the floor slab through the keel frame. The keel frame is formed by overlapping a horizontal keel and a vertical keel. A fireproof layer is supported on the galvanized plate, and a support bracket fixedly connected to the galvanized plate is additionally provided. The support bracket is located between adjacent vertical keels. Both ends of the support bracket are turned outwards to form flanges perpendicular to the support bracket. The support bracket is fixedly connected to the vertical keels on both sides through the flanges of the support bracket.

[0007] The galvanized plate has a groove-shaped structure. One side of the galvanized plate is fixedly connected to the floor slab, and the other side of the galvanized plate is fixedly connected to the vertical keel through the support bracket. The fireproof layer is filled in the groove of the galvanized plate.

[0008] The support bracket has an L-shaped strip structure. The support bracket is located at the included angle of the galvanized plate close to the keel frame. The support bracket is fixedly connected to the galvanized plate with screws. The head of the screw is located in the groove of the galvanized plate and is blocked by the fireproof layer.

[0009] A limiting plate is further provided on the bearing bracket. A plurality of groups of limiting plates are arranged at intervals along the length direction of the bearing bracket. A limiting groove is formed among the limiting plate, the floor slab, and the galvanized plates on the upper and lower sides, and a heat insulation layer is filled in the limiting groove.

[0010] Reinforcing ribs are further provided on the limiting plate, and a series connection is formed among multiple groups of limiting plates by means of the reinforcing ribs.

[0011] The beneficial effects of the present utility model are as follows:

[0012] In the present utility model, a bearing bracket is additionally provided. The bearing bracket is erected between adjacent vertical keels and supports the galvanized plate, so that the galvanized plate does not need to be fixedly connected to the horizontal keel with screws, ensuring the structural integrity of the horizontal keel. When the flanging of the bearing bracket is connected to the vertical keel, only a few screws are required to complete the fixed connection between the two. Compared with the traditional method of fixedly connecting the galvanized plate to the horizontal keel with screws, the number of required screws is greatly reduced, thereby reducing the damage to the keel frame structure and ensuring the building quality.

[0017] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0018] Specific embodiment, as Figures 1-3 shown, the present utility model provides an installation structure for sealing galvanized plates between floors of a curtain wall, including a floor slab 1, a galvanized plate 2 and a keel frame respectively fixedly connected to the floor slab 1. The curtain wall 11 is fixedly connected to the floor slab 1 by means of the keel frame. The keel frame is formed by overlapping a horizontal keel 3 and a vertical keel 4. A fireproof layer 5 is supported on the galvanized plate 2. A bearing bracket 6 fixedly connected to the galvanized plate 2 is additionally provided. The bearing bracket 6 is located between adjacent vertical keels 4. The two ends of the bearing bracket 6 are turned outwards to form flangings 7 perpendicular to the bearing bracket 6. The bearing bracket 6 is fixedly connected to the vertical keels 4 on both sides by means of the flangings 7 of the bearing bracket 6.

[0019] Currently, the fireproof layer 5 is usually supported by the galvanized sheet 2. However, during the fixing process of the galvanized sheet 2, it is usually fixed to the horizontal keel 3 with screws. And to ensure the stability of the fixing structure, a relatively large number of screws are set, which results in a large number of screw holes on the horizontal keel 3, damaging the structural strength of the horizontal keel 3 itself and affecting the building quality.

[0020] Therefore, in the present utility model, a support bracket 6 is additionally provided. The support bracket 6 is erected between adjacent vertical keels 4 and supports the galvanized sheet 2, so that the galvanized sheet 2 does not need to be fixed to the horizontal keel 3 with screws, ensuring the structural integrity of the horizontal keel 3. When the flanging 7 of the support bracket 6 is connected to the vertical keel 4, only a few screws are needed to complete the fixed connection between the two. Compared with the traditional method of fixing the galvanized sheet 2 to the horizontal keel 3 with screws, the number of required screws is greatly reduced, thereby reducing the damage to the keel frame structure and ensuring the building quality.

[0021] As Figure 1 shown, the galvanized sheet 2 has a groove-shaped structure. One side of the galvanized sheet 2 is fixedly connected to the floor slab 1, and the other side of the galvanized sheet 2 is fixedly connected to the vertical keel 4 with the help of the support bracket 6. The fireproof layer 5 is filled in the groove of the galvanized sheet 2. The groove-shaped galvanized sheet 2 can form a supporting effect on the fireproof layer 5, and the fireproof layer 5 can be fireproof rock wool.

[0022] As Figures 1-2 shown, the support bracket 6 has an L-shaped long strip structure. The support bracket 6 is located at the corner of the galvanized sheet 2 close to the keel frame. The support bracket 6 is fixedly connected to the galvanized sheet 2 with screws. The head of the screw is located in the groove of the galvanized sheet 2 and is shielded by the fireproof layer 5. In the traditional structure of the galvanized sheet 2 and the horizontal keel 3, the screw positions may be soaked by rainwater, resulting in the screws rusting and being corroded, and the corrosion may even cause fracture. However, in the present utility model, the screws are shielded by the fireproof layer 5, and the fireproof layer 5 has a certain water absorption capacity, playing a waterproof role for the screws.

[0023] As Figure 1 and Figure 3 shown, a limiting plate 8 is further provided on the support bracket 6. The limiting plates 8 are arranged in multiple groups at intervals along the length direction of the support bracket 6. A limiting groove is formed between the limiting plates 8, the floor slab 1, and the galvanized sheets 2 on the upper and lower sides. The limiting groove is filled with a heat insulation layer 9. In the traditional curtain wall 11 structure, the heat insulation layer 9 is usually a long whole piece to ensure that the heat insulation layer 9 is constrained and fixed by the vertical keel 4. However, the overly long heat insulation layer 9 will increase the construction difficulty for construction workers. Therefore, in the present utility model, multiple groups of spaced limiting plates 8 are provided below the support bracket 6, and each group of limiting plates 8 can constrain a group of heat insulation layers 9, so that a long heat insulation layer 9 between adjacent vertical keels 4 is changed into multiple shorter heat insulation layers 9, and the shorter heat insulation layers 9 are more convenient for construction workers to install.

[0024] As Figure 1 and Figure 3 shown, a reinforcing rib 10 is further provided on the limit plate 8. Multiple groups of limit plates 8 are connected in series by means of the reinforcing rib 10, and the setting of the reinforcing rib 10 further increases the overall structural strength of the curtain wall 11.
