Description

Technical Field

[0001] The present invention relates to the technical field of skylights, and particularly to a new type of waterproof profile for smoke exhaust skylights, a corner fitting, and a smoke exhaust skylight composed thereof. Background Art

[0002] A smoke exhaust skylight usually consists of multiple frame profiles and glass or light-transmitting panels, etc. The corner positions where the frame profiles are connected to each other are butt joints. These butt joints can be right angles, acute angles or obtuse angles, and the specific shapes and angles are determined according to design and functional requirements. The butt joint is a key part of the smoke exhaust skylight structure. It is necessary to ensure the stability of the connection and also do a good job in sealing and waterproofing to prevent rainwater, dust, etc. from entering the room. However, due to certain defects in the design of the frame profiles and the relatively weak structure of the butt joint assembly of the frame profiles themselves, it is very difficult to achieve a completely tight fit at the butt joint of the skylight, which in turn leads to an unsatisfactory sealing and waterproofing effect at this place. At the same time, due to many inevitable factors, rainwater will seep into the interior of the frame profile from the gap between the contact surfaces of the frame profile and the glass or light-transmitting panel in the smoke exhaust skylight, and then seep into the room from the connection of the butt joint. Therefore, it is difficult for the existing frame profiles on the market to achieve a good waterproof function.

[0003] In order to effectively overcome the water seepage defect at the butt joint of the frame profile, the common practice on the market at present is to apply glue at the butt joint. However, under the action of the long-term natural environment, the glue is prone to aging, cracking and other situations. For example, in areas with frequent high-temperature exposure and rain erosion, the service life of the glue will be greatly shortened. Once the glue fails, the water seepage defect at the butt joint will be exposed again, and the problem of water seepage cannot be completely solved. Therefore, how to effectively solve the water seepage problem at the butt joint of the frame profile is the top priority at present. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above problems, and provide a new type of waterproof profile for smoke exhaust skylights, a corner fitting applied to the new type of waterproof profile for smoke exhaust skylights, and a smoke exhaust skylight composed of the new type of waterproof profile for smoke exhaust skylights and the corner fitting.

[0005] The purpose of the present invention is achieved through the following solutions: A new type of waterproof profile for smoke exhaust skylights mainly consists of a profile main body. At both ends of the profile main body, butt joint end faces are respectively provided. The profile main body is composed of a profile main board, a clamping plate arranged at the top position of the upper end of the profile main board, a water collecting groove arranged at the upper end position of the profile main board, and a corner fitting cavity arranged on the profile main board and below the water collecting groove; a water blocking plate is arranged inside the water collecting groove and at the position of the butt joint end face, and an installation groove is formed between the clamping plate and the upper edge of the water collecting groove.

[0006] The corner position of the water receiving trough is composed of a trough bottom edge, an inner trough vertical edge connected to the trough bottom edge and close to the indoor side, and an outer trough vertical edge connected to the trough bottom edge and close to the outdoor side. The baffle plate has at least a baffle edge fixedly connected to the inner trough vertical edge as a whole and a bottom edge connected to the trough bottom edge as a whole.

[0007] The baffle edge of the baffle plate, the inner trough vertical edge and the trough bottom edge meet at a point A, the upper end of the baffle edge forms a point C with the inner trough vertical edge, and the end of the bottom edge of the baffle plate close to the outer trough vertical edge forms a point B with the trough bottom edge; the length between the point A and the point B is greater than 1 mm, and the length between the point A and the point C is greater than 0.1 mm.

[0008] Furthermore, the baffle plate is a polygon in the same plane or a polygon in non - same planes.

[0009] To ensure that rainwater does not accumulate, a water - falling hole is also provided at the position of the trough bottom edge and at the end face of the corner.

[0010] As one of the preferred ways, the water - falling hole is located on the extension line of the bottom edge of the baffle plate. As the second preferred way, part of the water - falling hole is located on the extension line of the bottom edge of the baffle plate and part of it is located on the bottom edge of the baffle plate.

[0011] According to requirements, the water - falling hole can be made in a strip shape, and its width is between 0.5 and 20 mm.

[0012] Another object of the present invention is to provide a corner fitting applied to the new type of waterproof profile for smoke exhaust skylights. The corner fitting is composed of a first corner block and a second corner block, and corner fitting inclined surfaces are provided at the upper ends of the first corner block and the second corner block.

[0013] Furthermore, more than one protruding edge is provided on the corner fitting inclined surface, and the overall external shape formed by the protruding edge and the corner fitting matches the internal shape of the corner fitting cavity.

[0014] To facilitate the fixation of the corner fitting, grooves are provided on both side surfaces of the first corner block and the second corner block.

[0015] According to requirements, the present invention can also be provided with mutually - communicating through - cavities inside the first corner block and the second corner block.

[0016] The present invention also provides a smoke exhaust skylight composed of a new type of waterproof profile for smoke exhaust skylights and corner fittings. The smoke exhaust skylight is at least composed of two relatively - arranged window sashes. Each window sash is composed of a lighting plate, 4 profile bodies, and corner fittings arranged inside the corner fitting cavities of adjacent two profile bodies; the installation grooves on all the profile bodies are connected end to end in sequence to form an installation ring groove, and the lighting plate is embedded and installed in the installation ring groove.

[0017] On all sides of the daylighting board, there are edge guards. When these edge guards are connected end to end in sequence, they form a circular edge guard. When the daylighting board is installed inside the installation ring groove, the circular edge guard can cover the upper edge of the water collection trough inside it.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] (1) In the present invention, a water baffle is provided inside the water collection trough of the waterproof profile of the new smoke exhaust skylight and at the position of the corner joint. Not only can the water collection trough collect the infiltrated rainwater to prevent the water from flowing around inside the profile, but also the setting of the water baffle can further block the water flow, avoiding the rainwater in the water collection trough from infiltrating into the room through the corner joint of the profile. Through the two-layer waterproof design, the technical defect of easy water infiltration at the corner joint can be completely solved.

[0020] (2) In the present invention, chamfers are provided at the upper ends of the first corner block and the second corner block of the angle code, and the chamfers of the angle code can further drain the rainwater flowing in from the bottom of the water collection trough to the side of the angle code cavity away from the indoor direction, accelerating the flow rate of the rainwater and preventing the rainwater from accumulating at the corner joint position of the angle code cavity, further enhancing the waterproof effect.

[0021] (3) In the present invention, edge guards are provided on all sides of the daylighting board. When these edge guards are connected end to end in sequence, a circular edge guard is formed on the daylighting board. When the daylighting board is installed inside the installation ring groove formed by the installation groove of the profile main body, the circular edge guard can cover the upper edge of the water collection trough inside it. It can not only prevent water from infiltrating at the connection between the daylighting board and the profile, but also play a certain protective role for the daylighting board to prevent its edge from being damaged by collision or the like.

Detailed implementation manners

[0037] The present invention will be further described in detail below in conjunction with embodiments, but the implementation manners of the present invention are not limited thereto.

[0038] Embodiment 1

[0039] As Figures 1 to 7As shown in the figure, at both ends of the profile body 1 of the novel smoke exhaust skylight waterproof profile of the present invention, corner bumps 2 are respectively formed, and the vertical end faces formed on the profile body 1 along the side edges of the corner bumps 2 are corner bump end faces 21. Different angles can be formed by docking the corner bump end faces 21 between two profile bodies 1. For example, if the corner bump 2 of one profile body 1 is 45°, then when two profile bodies 1 are combined by docking the corner bump end faces 21, a 90-degree angle can be formed, that is, the two profile bodies 1 are perpendicular to each other; another example is when the corner bump 2 of one profile body 1 is 60°, then when two profile bodies 1 are combined by docking the corner bump end faces 21, a 120° angle can be formed, that is, an obtuse angle is formed between the two profile bodies 1; and another example is when the corner bump 2 of one profile body 1 is 30°, then when two profile bodies 1 are combined by docking the corner bump end faces 21, a 60° angle can be formed, that is, an acute angle is formed between the two profile bodies 1.

[0040] In this embodiment, the corner bumps 2 at both ends of the profile body 1 are both 45°, and the profile body 1 is composed of a profile main board 11, a clamping board 10 arranged at the top position of the upper end of the profile main board 11, a water receiving groove 12 arranged at the upper end position of the profile main board 11, and an angle code cavity 13 arranged on the profile main board 11 and located below the water receiving groove 12. A water blocking board 3 is arranged inside the water receiving groove 12 and at the position of the corner bump 2, and an installation groove 14 for installing a lighting board 4 is formed between the clamping board 10 and the upper edge of the water receiving groove 12.

[0041] The water receiving groove 12 is used to receive rainwater that enters the interior of the profile body 1 through various channels, and the collected rainwater is discharged into the interior of the angle code cavity 13 through a number of drainage holes 15 arranged at the bottom of the water receiving groove 12 and communicated with the angle code cavity 13. At the same time, a number of drainage holes 15 are also arranged at the bottom of the angle code cavity 13 to discharge the rainwater flowing into the interior of the angle code cavity 13 to the outside.

[0042] The specific structure of the water receiving groove 12 is as Figure 9 shown. This structure is the structure of the water receiving groove 12 at the corner bump end face 21. The water receiving groove 12 is composed of a groove bottom edge 121, a groove inner vertical edge 122 connected to the groove bottom edge 121 and close to the indoor side, and a groove outer vertical edge 123 connected to the groove bottom edge 121 and close to the outdoor side. The water blocking board 3 is polygonal, and it has at least one blocking edge fixedly connected and integrally formed with the groove inner vertical edge 122 and a bottom edge connected and integrally formed with the groove bottom edge 121, and the other edges and the overall shape of the water blocking board 3 can be set arbitrarily according to needs. For example, it can be Figure 9 the triangle shown, or it can be Figure 10The trapezoid shown. Correspondingly, all sides of the water baffle 3 can be in the same plane or not in the same plane. The present invention preferably adopts the method of setting all sides of the water baffle 3 in the same plane. Unless otherwise specified, the water baffle 3 described below refers to the case where all its sides are set in the same plane.

[0043] The bottom edge 121 of the water collecting groove 12 can be horizontally arranged, and its structure is as Figure 9 shown. The bottom edge 121 can be inclinedly arranged, and its structure is as Figure 8 shown.

[0044] Since the water baffle 3 is used to block the rainwater in the water collecting groove 12 from flowing into the corner 2, the baffle edge, the inner vertical edge 122 of the groove and the bottom edge 121 of the groove need to be connected to each other, and the three meet and form an intersection point A; after the baffle edge and the inner vertical edge 122 of the groove are integrally formed, an intersection point C is formed between its upper end and the inner vertical edge 122 of the groove; an intersection point B is formed between the bottom edge of the water baffle 3 and the end close to the outer vertical edge 123 of the groove and the bottom edge 121 of the groove. That is, the water baffle 3 forms three intersection points in the water collecting groove 12, namely intersection point A, intersection point B and intersection point C. To ensure the water blocking effect of the present invention and comprehensively consider factors such as the internal space size of the entire profile body 1, the length between intersection point A and intersection point B in the present invention is greater than 1 mm, and the length between intersection point A and intersection point C is greater than 0.1 mm.

[0045] According to different manufacturing processes, the water baffle 3 can be formed into a corresponding shape from a separate material in the above manner and then fixed inside the water collecting groove 12 by welding or bonding, etc., or can be directly formed by folding or stamping the bottom edge 121 of the water collecting groove 12.

[0046] In order to prevent rainwater from accumulating at the corner end face 21 and to discharge the rainwater in the water collecting groove 12, a water drain hole 16 is further provided inside the water collecting groove 12 and at the position of the corner end face 21. The position of the water drain hole 16 can be set according to actual needs. For example, it can be set on the extension line of the bottom edge of the water baffle 3, or part of the water drain hole 16 is on the extension line of the bottom edge of the water baffle 3 and part is on the bottom edge of the water baffle 3.

[0047] Of course, according to actual needs, the water drain hole 16 can also be set in two halves. One half is set on the bottom edge 121 of the water collection groove 12 of one profile main board 1, and the other half is set on the bottom edge 121 of the water collection groove 12 of another profile main board 1 connected thereto. When the two profile main boards 1 are assembled and connected, the two half water drain holes 16 on the two profile main boards 1 will form a complete water drain hole 16. Similarly, according to needs, the water drain hole 16 can also be only set at the edge of one water collection groove 12 and communicate with the connected profile main board that matches it at the same time.

[0048] The shape of the water drain hole 16 can be any shape. For example, it can be made into a circular shape, an oval shape or a long strip shape. When it is made into a long strip shape, the width of the water drain hole 16 needs to be set between 0.5 and 20 mm.

[0049] According to needs, a water drain hole extension end 161 can also be formed on the water drain hole 16 in this embodiment to further enhance the drainage effect of the baffle 3 in the water collection groove 12.

[0050] The outer side surface of the baffle 3 (i.e., the side surface facing the miter end face) can be in the same vertical plane as the miter end face 21. At this time, after the two corresponding profile bodies 1 are connected, the two baffles 3 will be closely attached to each other, and its structure is as Figure 11 shown. On the contrary, when the plane where the baffle 3 is located is not in the same vertical plane as the miter end face 21, then after the two corresponding profile bodies 1 are connected, a baffle gap 162 will be formed between the outer side surfaces of the two baffles 3, and its structure is as Figure 12 shown.

[0051] It should be noted that, as a special case, when the baffle 3 is formed by folding or stamping the bottom edge 121 of the water collection groove 12, since a gap will be formed between the outer side surface of the baffle 3 and the miter 2 end face of the profile body 1, when the two corresponding profile bodies 1 are connected, the gaps on each profile body 1 will combine to form a complete gap hole, and this gap hole can be used for drainage. Therefore, in this case, a water drain hole 16 that is connected or not connected to the gap hole can be set on the bottom edge 121, or the water drain hole 16 can also be not set.

[0052] The corner code cavity 13 in this embodiment is used to install the corner code 5, and two adjacent profile bodies 1 can form a whole through the corner code 5. The structure of the corner code 5 is as Figure 4 、 Figure 5 shown. It is composed of a first corner block 51 and a second corner block 52, and both the first corner block 51 and the second corner block 52 have a certain thickness. At the same time, corner code inclined surfaces 6 are provided at the upper ends of the first corner block 51 and the second corner block 52.

[0053] The first corner block 51 has an inner side surface 511 of the first corner block and an outer side surface 512 of the first corner block, and the second corner block 52 has an inner side surface 521 of the second corner block and an outer side surface 522 of the second corner block. Among them, the included angle formed between the inner side surface 511 of the first corner block and the inner side surface 521 of the second corner block is the same as the degree of the corner collision 2 formed between the two profile bodies 1.

[0054] All the corner code inclined surfaces 6 need to face the outer vertical edge 123 of the water collection groove 12, that is, the top edge of the inner side surface 511 of the first corner block 51 is higher than the top edge of the outer side surface 512 of the first corner block, and the top edge of the inner side surface 521 of the second corner block 52 is higher than the top edge of the outer side surface 522 of the second corner block. After setting according to the above structure, the rainwater dripping from the drain hole 15 at the bottom of the water collection groove 12 will directly drip on the corner code inclined surface 6. Since the corner code inclined surface 6 faces the outer vertical edge 123 of the water collection groove 12, the rainwater will flow along the corner code inclined surface 6 and through the outer side surface 512 of the first corner block and the outer side surface 522 of the second corner block into the bottom of the corner code cavity 13, and finally be discharged outdoors through the drain hole 15 at the bottom of the corner code cavity 13.

[0055] As another solution, in this embodiment, one or more protruding edge blocks 7 can also be provided on the corner code inclined surface 6, and the overall external shape formed by the protruding edge block 7 and the corner code 5 matches the internal shape of the corner code cavity 13. For example, when the corner code cavity 13 is a rectangular cavity, the top of the protruding edge block 7 is a horizontal plane, and it forms a rectangle together with other parts of the corner code 5, and the shape and size of this rectangle should match the shape and size of the rectangular corner code cavity 13, so as to strengthen the fastening between the corner code 5 and the corner code cavity 13 through the protruding edge block 7.

[0056] As needed, the corner code 5 in this embodiment can be made into a solid body, and its structure is as Figure 4 , 5 shown, or a through cavity 8 can be provided inside the corner code 5, that is, a mutually connected through cavity 8 is provided inside the first corner block 51 and the second corner block 52 respectively, and its structure is as Figure 6 shown. Among them, Figure 6 only the structure when one through cavity 8 is provided on each of the first corner block 51 and the second corner block 52 is shown, and the number of through cavities 8 can be set according to the lengths of the first corner block 51 and the second corner block. At the same time, the through cavity 8 on the first corner block 51 and the through cavity 8 on the second corner block 52 can be mutually connected or independently provided, and it does not affect its overall performance.

[0057] As another solution, when a through cavity 8 is provided inside the first corner block 51 and the second corner block 52, the through cavity 8 can divide the first corner block 51 and the second corner block 52 into two opposite parts, and the corner code inclined surface 6 only needs to be provided on the part where the inner side surfaces of the first corner block 51 and the second corner block 52 are located. In this way, the rainwater dripping on the corner code inclined surface 6 can be drained into the through cavity 8. Figure 13 The partial sectional structure diagram of this solution is shown. The corner code inclined surface 6 is provided on the inner side surface 511 of the first corner block of the first corner block 51, and the corner code inclined surface 6 is not provided on the outer side surface 512 of the first corner block.

[0058] To further enhance the fastening performance between the corner code 5 and the profile body 1, a number of grooves 53 are provided on both the outer side surface 512 of the first corner block and the outer side surface 522 of the second corner block. When the corner code 5 is arranged inside the corner code cavity 13, the side wall of the corner code cavity 13 can be stamped with bumps matching the grooves 53 on the outside of the corner code cavity 13, so as to ensure that the corner code 5 can be firmly fixed inside the corner code cavity 13 without detachment.

[0059] Embodiment 2

[0060] This embodiment is a smoke exhaust skylight composed of the new type of waterproof profile for smoke exhaust skylight, the corner code 5 and the lighting panel 4 recorded in Embodiment 1, and its overall structure is as Figure 14 shown, and its end face structure is as Figure 7 shown. In this embodiment, the smoke exhaust skylight is composed of two relatively arranged window sashes 17. Each window sash 17 is fixedly installed on the corresponding foundation or section steel through a hinge or a hinge. Each window sash 17 is composed of a lighting panel 4, 4 profile bodies 1, and a corner code 5 arranged inside the corner code cavity 13 of two adjacent profile bodies 1.

[0061] In this embodiment, the angles of the corner contacts 2 at both ends of the profile body 1 are both 45°, and the included angle formed between the first corner block 51 and the second corner block 52 of the corner code 5 should be 90°, so as to ensure that when the corner code 5 is inserted into the corner code cavity 13 of two adjacent profile bodies 1, these two profile bodies 1 can form a right angle. Since the corner code 5 is arranged inside the corner code cavity 13, it is Figure 14 not shown in the figure. Since an installation groove 10 is provided on each profile body 1, when 4 profile bodies 1 are fixedly connected end to end in sequence to form a rectangle, the installation grooves 10 on each profile body 1 will also be connected end to end in sequence to form a rectangular installation ring groove, that is, the rectangular installation ring groove is formed by connecting all the installation grooves 10 end to end in sequence.

[0062] The lighting panel 4 is embedded and installed in the installation ring groove. To further enhance the anti-leakage effect, the lighting panel 4 is provided with a flange 9 on all its sides. After the flanges 9 are connected end to end in sequence, they also form a rectangular ring-shaped flange. When the lighting panel 4 is installed inside the installation ring groove, the ring-shaped flange can cover the upper edge of the water collecting trough 12 inside it, thereby preventing rainwater from seeping into the room through the gap between the lighting panel 4 and the water collecting trough 12.

[0063] As described above, the present invention can be well implemented.
