The supporting longitudinal beams 21 and the supporting transverse beams 22 can be connected together by welding, U-shaped or L-shaped corner connectors, screws and other common methods and components.
As shown in fig. 3, two adjacent left and right skylight units 1 are separated from each other, a waterproof strip 81 is sandwiched between the gaps between the two adjacent left and right sashes 12 to form a first waterproof layer, most of the water is blocked outside the room, the waterproof strip 81 is installed on the outer end surface of the sash frame 123, and an upper layer and a lower layer can be provided to enhance the waterproof effect. In addition, a concave position is enclosed between the two adjacent horizontal frames 112 of the window frame 11 and the supporting beam 22 supported below the horizontal frames to form a built-in first drainage channel 51 with an upward opening, so that a small amount of incoming water can be smoothly drained through the first drainage channel 51, and the structure is used as a second waterproof layer. By the built-in drainage structure, a drainage ditch does not need to be additionally arranged outside the skylight unit, so that the height of the raised part of the skylight can be greatly reduced. In the first drainage channel 51, the bottom of the transverse frame 112 can be fixedly connected to the supporting beam 22 by screws, and the joints of the screws are sealed for water prevention. In this embodiment, the bottoms of the adjacent transverse frames 112 of the two adjacent left and right window frames 11 are supported by the same transverse frame 112, which not only saves the installation time, but also improves the waterproof effect.
In order to further improve the waterproof performance, an inner waterproof rubber strip 83 and an outer waterproof rubber strip 83 are further arranged between the window frame 11 and the window sash 12 to form a third waterproof rubber strip and a fourth waterproof rubber strip, the outer waterproof rubber strip 83 can be installed at the bottom of the outer side of the window sash frame 123, the inner waterproof rubber strip 83 can be installed at the top of the inner side of the window frame 11, the position of the outer waterproof rubber strip 83 is lower, and the position of the inner waterproof rubber strip 83 is higher. In addition, in the present embodiment, the outer periphery of the window sash 12 protrudes beyond the outer periphery of the window frame 11, which is more favorable for waterproofing. When the skylight is closed, the four waterproof layers can ensure that water cannot enter the room, and the waterproof performance is greatly improved.
The skylight system with the built-in drainage structure can be applied to a roof with skylight units on the same plane, in this case, the same built-in drainage structure can be adopted between the skylight units adjacent to each other in the front and the back as that between the skylight units adjacent to each other in the left and the right, and the longitudinal drainage grooves and the transverse drainage grooves are communicated with each other and are communicated with the outside.

Similarly, the inner and outer waterproof rubber strips 83 arranged between the window frame 11 and the window sash 12 form a third waterproof strip and a fourth waterproof strip.
As shown in fig. 4, the front part of the supporting longitudinal beam 21 at the rear part of the supporting framework 2 is convexly provided with a supporting platform 23, the top part is convexly provided with an inserting part 24, and the supporting longitudinal beam 21 at the front part of the supporting framework 2 is provided with a slot 25 with a downward opening. The longitudinal frame 111 at the rear side of the window frame 11 supports and is fixed on the supporting platform 23 by screws, the insertion part 24 is inserted into the insertion slot 25 of the front supporting longitudinal beam 21 below the rear adjacent skylight unit 1, and the gap at the insertion part is filled with sealant and provided with a waterproof adhesive tape to improve the waterproof performance. The supporting longitudinal beam 21 at the rear part of one skylight unit 1 and the supporting longitudinal beam 21 at the front part of the skylight unit 1 adjacent to the rear part are respectively fixed at the front side and the rear side of the support 3 by bolts. The structure enables the front and the rear supporting frameworks 2 to be stressed together, so that systematic stress and water resistance are formed, and the structure is more reliable.
A rear side sealing edge 122 is fixed at the top of the rear side of the window sash 12 of the front skylight unit 1, a waterproof rubber strip 84 is installed on the rear side sealing edge 122, a cover sheet 6 is fixedly installed on the front support longitudinal beam 21 below the rear skylight unit 1, and when the skylight is closed, the waterproof rubber strip 84 is clamped between the bottom of the cover sheet 6 and the rear side sealing edge 122 to form a first waterproof path. The concave position enclosed between the rear longitudinal frame 111 of the window frame 11 and the rear support longitudinal beam 21 and the insertion part 24 thereof forms a built-in third drainage groove 53 which is used as a second waterproof, the third drainage groove 53 is communicated with the first drainage groove 51, and the cover sheet 6 covers the third drainage groove 53. Similarly, the inner and outer waterproof rubber strips 83 arranged between the window frame 11 and the window sash 12 form a third waterproof strip and a fourth waterproof strip. This makes it possible to incorporate a drainage structure around the skylight unit 1, thereby ensuring the reliability of water resistance and eliminating the need for a separate drainage ditch around the skylight unit.
It can be seen that the skylight system of the invention is provided with a built-in drainage channel on each skylight unit, the drainage channel is closed and is formed into a first waterproof layer by a waterproof rubber strip, the built-in drainage channel is used as a second waterproof layer, and the inner and outer waterproof rubber strips arranged between the window frame 11 and the window sash 12 form a third waterproof layer and a fourth waterproof layer.
