Description

Technical Field

[0001] The invention belongs to the technical field of building roof drainage, and in particular relates to a skylight drainage structure. Background Art

[0002] A skylight is a building enclosure structure that consists of a light-transmitting panel and a supporting system, does not share the effects on the main structure, and has an angle with the horizontal direction of less than 75°. In order to meet the lighting requirements, the panels of the skylight are generally made of glass, polycarbonate board (PC board), ETFE film and other materials.

[0003] In order to make the skylight more transparent and light, designers and owners often use steel columns as supporting components. The larger the area of ​​the skylight, the more severe the drainage problem. Traditional skylight steel columns only serve as support for the skylight. Rainwater collected by the skylight is often discharged freely, or a drainage pipe is set outside the skylight to drain the rainwater to the ground ditch or other locations through an exposed drainage pipe. For details, please refer to the patent document with publication number CN211817493U. The skylight drainage structure in the prior art is mostly in the form of drainage gutters with exposed drainage pipes.

[0004] Rainwater collected by the skylight can be discharged to the ground through either free drainage or a drainage pipe installed outside the skylight. Both methods have certain disadvantages. First, the free drainage of rainwater from the skylight gives people a very poor experience, and at the same time, it will cause the eaves panel of the skylight to sag and pollute the panel. The installation of a drainage pipe outside the skylight will affect the facade effect. Summary of the invention

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 9As shown, the present invention includes a skylight roof 10, a support column and a drainage system, wherein the drainage system includes a water collection tank 31 and a drainage pipe 32, the water collection tank 31 is fixedly arranged at the edge of the skylight roof 10, one side of the water collection tank 31 is connected to the top surface of the skylight roof 10, the inlet end of the drainage pipe 32 is connected to the bottom of the water collection tank 31, and the outlet end of the drainage pipe 32 is connected to the drainage main pipe network pre-buried under the ground 40, and the support column includes a column 21 and an inclined support column 22, the lower end of the column 21 is fixedly connected to the ground 40, and the upper end of each column 21 is fixedly connected to a plurality of inclined support columns 22 (part of which is inclined and extends upward) extending obliquely. The upper end of at least one inclined support column 22 is fixedly connected to the bottom of the water collecting tank 31 (generally, each column 21 can be provided with one or two inclined support columns 22 dedicated to arranging the drainage pipe 32), and the drainage pipe 32 is inserted into the inner cavity of the inclined support column 22 from the upper end surface of the inclined support column 22, and passes through the inner cavity of the inclined support column 22 and the inner cavity of the column 21 in turn, and then extends to below the ground. The support columns with the drainage pipe 32 arranged inside are all made of steel pipe structure, and the inclined support column 22 is provided with at least one drainage pipe connection support node. The column 21 is provided with at least one drainage pipe connection support node, the support column at the location of the drainage pipe connection support node includes an upper steel pipe column 24 and a lower steel pipe column 25 connected by an annular weld 23, the drainage pipe 32 at the location of the drainage pipe connection support node includes an upper water pipe 33 and a lower water pipe 34 connected by plug-in matching, the lower end of the upper water pipe 33 is inserted into the upper end inner cavity of the lower water pipe 34, and at least one circle of sealing strip 35 (preferably two circles) is provided between the matching surface of the upper end inner wall of the lower water pipe 34 and the outer wall of the upper water pipe 33, the upper steel pipe column 24 The inner wall of the lower steel pipe column 25 is welded and fixed with a first partition 26 (usually fixed by spot welding) near the lower end of the pipe mouth, and the first partition 26 has a first limiting hole for the upper water pipe 33 to pass through, and the inner wall of the first limiting hole and the outer wall of the upper water pipe 33 are connected by a first rubber sleeve 28; the inner wall of the lower steel pipe column 25 is welded and fixed with a second partition 27 (usually fixed by spot welding) near the upper end of the pipe mouth, and the second partition 27 has a second limiting hole for the lower water pipe 34 to pass through, and the inner wall of the second limiting hole and the outer wall of the lower water pipe 34 are connected by a second rubber sleeve 29. The drain pipe 32 is generally preferably made of stainless steel pipe, and the sealing strip 35 is generally preferably made of EPDM sealing strip.

[0026] It is understandable that the drain pipe 32 needs to pass through the inner cavity of the oblique support column 22 and the inner cavity of the column 21 in sequence and then extend to below the ground. The connecting fork area of ​​the oblique support column 22 and the column 21 must be provided with a corresponding steel joint 39. The oblique support column 22, the column 21 and the steel joint 39 are generally fixed as a whole by welding. The part where the drain pipe 32 passes through the steel joint 39 can be realized by an integrated elbow structure, or it can be connected by adding an elbow joint.

[0027] See also Figures 7 to 9 For each drainage pipe connection support node, during the specific assembly, the upper steel pipe column 24, the first partition plate 26, the first rubber sleeve 28, and the upper water pipe 33 can be assembled into an integral component one, and the lower steel pipe column 25, the second partition plate 27, the second rubber sleeve 29, the lower water pipe 34, and the sealing strip 35 can be pre-assembled into an integral component two, and then the integral component one and the integral component two are accurately aligned, and then the upper water pipe 33 at the node is correspondingly inserted into the lower water pipe 34, and then the upper steel pipe column 24 and the lower steel pipe column 25 at the node are welded and fixed.

[0028] To further facilitate assembly, the first rubber sleeve 28 is fixed to the first partition plate 26 through an annular slot, and the second rubber sleeve 29 is fixed to the second partition plate 27 through an annular slot. The lower water pipe 34 includes a lower water pipe body and a plug sleeve 36 that are coaxially arranged and connected together. The lower water pipe body has the same diameter as the upper water pipe 33. The inner diameter of the plug sleeve 36 is larger than the outer diameter of the upper water pipe 33. The upper water pipe 33 is connected to the plug sleeve 36. The lower water pipe body has the same diameter as the upper water pipe 33, which can make drainage smoother. In addition, since the inner diameter of the plug sleeve 36 is larger than the outer diameter of the upper water pipe 33, the transition connection between the plug sleeve 36 and the lower water pipe body can also play an axial limiting role on the upper water pipe 33.

[0029] To further facilitate assembly, a sealing groove for accommodating the sealing strip 35 is provided on the inner wall of the plug-in sleeve 36 .

[0030] To make drainage smoother, the inlet end of the drainage pipe 32 is connected to the water collection tank 31 through the water inlet bucket 37.

[0031] In order to avoid clogging of the drainage system, necessary filtering devices should be considered, which can be set as a whole on the top of the water collection tank 31, or can be designed separately for each drainage pipe 32. The preferred solution is to set the water inlet on the top of the water collection tank 31 as a whole, and the water inlet on the top of the water collection tank 31 is closed by a filter grate 38, which can generally be made of stainless steel.

[0032] In order to further enhance the aesthetic effect of the building facade, the side of the water collection tank 31 away from the lighting roof 10 is equipped with an outer panel 40, and the outer panel 40 can generally be made of aluminum.
