Description

Technical Field

[0001] The invention relates to an energy-saving and heat-insulating multi-chamber crossbeam structure of a unit curtain wall, belonging to the technical field of unit curtain walls. Background Art

[0002] In the field of building curtain walls, unit curtain wall systems are widely used. The inner and outer cavities of traditional unit beams are usually directly connected and basically at the same elevation. In actual use, when encountering windy and rainy weather, due to the pressure difference between the external environment and the interior of the building, rainwater will flow along the outer cavity of the unit beam under the action of the pressure difference and enter the inner cavity through the drainage hole. Especially in the case of heavy rainfall or long duration of wind and rain, after a large amount of rainwater enters the inner cavity, the water accumulation in the inner cavity gradually increases and the water level rises. The inner sealing strip is mainly used to prevent a small amount of rainwater from penetrating under normal circumstances and impurities such as dust from entering the room. It is not designed for large amounts of water accumulation. When the water accumulation in the inner cavity reaches a certain height, the rainwater may break through the protection of the inner sealing strip and penetrate into the room, causing adverse effects on indoor decoration, equipment and personnel activities. Therefore, a new solution is needed to solve this problem. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] As attached Figure 1-3 As shown, an energy-saving and heat-insulating multi-chamber beam structure of a unit curtain wall described in the present invention comprises a unit column 1, a unit upper beam 3, a unit lower beam 2 and a curtain wall glass 4.

[0026] The unit upper cross beam 3 and the unit lower cross beam 2 are respectively connected and fixed to the upper and lower ends of the unit column 1, and the unit column 1 can be fixed to the main structure of the building by hanging. The upper and lower ends of the curtain wall glass 4 are respectively connected and fixed to the unit upper cross beam 3 and the unit lower cross beam 2 to form a unit plate; the upper and lower adjacent unit upper cross beams 3 and unit lower cross beams 2 are connected and fixed to each other.

[0027] The first chamber 21, the second chamber 22 and the third chamber 23 are sequentially arranged on the lower cross beam 2 of the unit from the outside to the inside. The first chamber 21, the second chamber 22 and the third chamber 23 are not connected to each other. A plurality of ventilation holes 211 are opened on the outer wall of the first chamber 21. The first chamber 21 is connected to the outside through the plurality of ventilation holes 211; a ventilation chamber 24 is arranged above the first chamber 21, and the ventilation chamber 24 is connected to the first chamber 21; a ventilator 25 is arranged at the upper end of the lower cross beam 2 of the unit, and the ventilator 25 is connected to the ventilation chamber 24, forming an indoor-ventilator 25-ventilation The ventilation structure of cavity 24-first cavity 21-outdoors ensures the ventilation effect of the fully enclosed curtain wall; considering that the thermal performance of the curtain wall at the above-mentioned ventilation structure is relatively weak, the first cavity 21, the second cavity 22 and the third cavity 23 that are not connected to each other are set on the lower cross beam 2 of the unit to block the heat loss in the room and improve the heat transfer coefficient of the curtain wall, thereby ultimately achieving the purpose of energy saving and heat preservation. At the same time, since the first cavity 21, the second cavity 22 and the third cavity 23 are not connected to each other, the water from the outside cannot enter the room through the lower cross beam 2 of the unit, thereby ensuring the waterproof effect.

[0028] In this embodiment, the ventilator 25 is configured as an inwardly opening window, and the ventilator 25 is fixedly connected to the middle of the upper end of the unit lower cross beam 2, and the upper end of the ventilator 25 is flush with the upper end of the unit lower cross beam 2 to ensure the appearance of the curtain wall.

[0030] A fourth chamber 31 and a fifth chamber 32 are sequentially arranged on the upper cross beam 3 of the unit from top to bottom. The fourth chamber 31 and the fifth chamber 32 are not connected to each other. The fourth chamber 31 and the fifth chamber 32 that are not connected to each other have the same function as the first chamber 21, the second chamber 22 and the third chamber 23 mentioned above, which are to block heat loss and improve the energy-saving and thermal insulation effect of the curtain wall.

[0032] An upper decorative line 41 is provided at the upper end of the curtain wall glass 4, one end of the upper decorative line 41 is connected and fixed to the upper cross beam 3 of the unit, and the other end of the upper decorative line 41 presses the upper end of the curtain wall glass 4 from the outside; a lower decorative line 42 is provided at the lower end of the curtain wall glass 4, one end of the lower decorative line 42 is connected and fixed to the lower cross beam 2 of the unit, and the other end of the lower decorative line 42 presses the lower end of the curtain wall glass 4 from the outside. By arranging the upper decorative line 41 and the lower decorative line 42, not only the appearance effect of the curtain wall glass 4 can be guaranteed, but also the upper and lower ends of the curtain wall glass 4 can be fixed, making the structure more stable.

[0033] An aluminum alloy glass support strip 5 is arranged between the lower end of the curtain wall glass 4 and the lower decorative line 42 to support the lower end of the curtain wall glass 4. During the actual installation process, a rubber pad can also be arranged on the top surface of the aluminum alloy glass support strip 5 as a buffer layer to prevent the lower end of the curtain wall glass 4 from directly contacting the aluminum alloy glass support strip 5 and causing damage to the curtain wall glass 4.

[0034] A water-shedding strip 6 is provided between the upper unit beam 3 and the lower unit beam 2 adjacent to each other to ensure the sealing between the adjacent unit panels, thereby further improving the waterproof effect.
