Problems solved by technology

[0003] However, due to the difficulty in forming the steel keel, in order to ensure the sealing strength of the sealing strip between the glass plate and the steel keel, it is necessary to form a rubber groove on the bearing surface of the steel keel. The glue groove itself has a certain width. On the one hand, the glue The groove makes the bearing surface no longer continuous, reduces the bearing area of ​​the glass plate, and increases the difficulty of forming the steel keel; on the other hand, to ensure sufficient bearing capacity for the glass plate, the width of the glue groove will bring the overall steel The increase in the width of the keel makes the steel keel itself unable to be slim, which affects the visual effect of the overall curtain wall

Embodiment 1

[0023] Such as figure 1 As shown, the first embodiment of the closed-cavity curtain wall system of the present invention includes a keel 1, a curtain wall panel 2, a pressure plate 3 and a locking bolt 4. Boss 11, between the outline of the main body of the keel 1 and the outline of the boss 11, there is a closed section 12 that makes the bearing surfaces on both sides of the boss 11 form a continuous surface and ensures that the inner cavity of the main body of the keel 1 is a closed cavity. The curtain wall panel 2 is carried on the keel 1 On the bearing surface of the bearing surface, the pressure plate 3 is pressed on the curtain wall panel 2, the locking bolt 4 is penetrated on the pressure plate 3 and is tightly connected with the boss 11, and a sealing strip 5 is arranged between the curtain wall panel 2 and the keel 1. A sinking groove 111 for preventing the sealing strip 5 from falling off is formed on the platform 11 . During installation, first install the sealing ...

Embodiment 2

[0028] Such as figure 2 As shown, the second embodiment of the closed-cavity curtain wall system of the present invention, the curtain wall system is basically the same as Embodiment 1, the only difference is that in this embodiment, the boss 11 is formed with a side above the sinking groove 111 Protrude 112 toward. The arrangement of the lateral protrusions 112 strengthens the sinking groove 111 and the boss 11 at the same time, improving the connection strength.

Embodiment 3

[0030] Such as image 3 As shown, the third embodiment of the closed cavity curtain wall system of the present invention, the curtain wall system is basically the same as the embodiment 1, the only difference is: in this embodiment, the top surface of the sinking groove 111 is set as a slope, and the top slope is made The glue sinking tank 111 is an internal expansion tank as a whole. The setting of the inclined surface makes the sinking groove 111 an internal expansion groove as a whole, which further improves the effect of preventing the sealing rubber strip 5 from falling off.

Abstract

The invention discloses a closed cavity type curtain wall system. The closed cavity type curtain wall system comprises a keel, a curtain wall plate, a pressing plate and a locking bolt, wherein a boss extending out of the outline of a keel body is formed on the bearing face of the keel; a closed section is arranged between the outline of the keel body and the outline of the boss, wherein the closed section enables the bearing faces on the two sides of the boss to form a continuous face and guarantees that an inner cavity of the outline of the keel body is a closed cavity; the curtain wall plate is borne on the bearing face of the keel; the pressing plate is arranged on the curtain wall plate in a pressing mode; the locking bolt is arranged on the pressing plate in a penetrating mode and connected with the boss in a fastened mode; a sealing rubber strip is arranged between the curtain wall plate and the keel; and a rubber sinking groove used for preventing the sealing rubber strip from falling off is formed in the boss. The curtain wall system has the advantages of being stable and reliable in structure, high in strength, thin in product and attractive in appearance.

Description

technical field [0001] The invention mainly relates to the field of building doors and windows, in particular to a closed-cavity curtain wall system. Background technique [0002] Curtain walls generally include steel curtain walls and aluminum curtain walls. Aluminum curtain walls are easy to form, but they do not have fire resistance. The existing steel curtain wall includes steel keel, steel pressure plate, glass plate and bolts. The glass plate is connected to the steel keel through the steel pressure plate and bolts. A sealing strip will be placed between the glass plate, the steel keel and the steel pressure plate to ensure the sealing performance. and connection strength. [0003] However, due to the difficulty in forming the steel keel, in order to ensure the sealing strength of the sealing strip between the glass plate and the steel keel, it is necessary to form a rubber groove on the bearing surface of the steel keel. The glue groove itself has a certain width. On...
