Description

Technical Field

[0001] The utility model relates to the field of construction, and in particular to an aviation obstruction light installation technology. Background Art

[0002] At present, there are a large number of super high-rise buildings that have been built or are under construction in my country. For buildings with height restrictions in the protection zone near the airport, or super high buildings outside the airport protection zone, according to the "Aviation Obstruction Lights (MH / T6012-2015)" promulgated by the state, such buildings need to be equipped with aviation obstruction lights protruding from the roof and facade curtain wall on the top floor and refuge floor respectively.

[0003] Existing aviation obstruction lights have a monotonous design and color, and lack standardized mounting bases. When installed on building roofs and exterior glass curtain walls, they appear obtrusive and lack refinement. They don't mesh well with the meticulously designed, standardized production of building curtain wall glass systems, significantly diminishing the facade's aesthetics and resulting in subpar results.

[0004] In order to standardize the facade curtain wall system of super high-rise buildings, it is necessary to uniformly design and produce the installation base of aviation obstruction lights to simplify the workflow and reduce installation risks. Utility Model Content

[0005] The purpose of the present utility model is to provide an external surface mounting device for an aviation obstruction light to solve at least one of the above-mentioned technical problems.

[0006] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0007] An aviation obstruction light facade installation device includes a steel structure base for connecting to a curtain wall and a support bracket to which the aviation obstruction light is fixed;

[0008] The support bracket includes a first support frame, a first flange is provided at the bottom of the first support frame, and at least three first bolt holes are formed on the first flange and pass through the first flange, and the first flange is connected to the steel structure base by bolts, and a second flange is provided at the top of the first support frame, and at least three second bolt holes are formed on the second flange and pass through the second flange;

[0009] The support bracket further includes a second support frame, the bottom of the second support frame is provided with a third flange, the third flange is provided with at least three third bolt holes extending vertically therethrough, the apertures of the third bolt holes are the same as the apertures of the second bolt holes, and the third flange is connected to the second flange by bolts;

[0010] The aviation obstruction light is fixed on the second supporting frame.

[0011] In the above design, the support bracket fixes the aviation obstruction light, and the aviation obstruction light has the need to adjust its direction. The integrated structure of the support bracket is difficult to meet the need to adjust the direction of the aviation obstruction light. Therefore, in this design, the support bracket includes a first support bracket and a second support bracket. Its beneficial effect is that the steel structure base is connected to the curtain wall to adapt to the overall style of the building's facade; the first support bracket is flange-connected to the steel structure base, playing a role of stable and firm support; the second support bracket is flange-connected to the first support bracket, and the aviation obstruction light is fixed on the second support bracket. When the aviation obstruction light needs to adjust its direction, the second support bracket can be rotated to achieve the need for direction adjustment.

[0012] Furthermore, the aviation obstruction light is a top-mounted aviation obstruction light, and a fourth flange is provided on the top of the second support frame. The fourth flange is provided with at least three fourth bolt holes running through the fourth flange, and the bottom of the top-mounted aviation obstruction light is provided with a fifth bolt hole at a position corresponding to the fourth bolt hole. The top-mounted aviation obstruction light is fixed to the top of the fourth flange by means of bolts passing through the fourth bolt hole and the fifth bolt hole.

[0013] In the above design, the top-mounted aviation obstruction light is fixed to the second support frame through a flange connection, which has the beneficial effects of simple structure, firm installation and low manufacturing cost.

[0014] Furthermore, the first support frame and the second flange are welded together, and the second support frame and the third flange and the fourth flange are welded together; a first rib in the shape of a right triangle is provided between the first support frame and the second flange, and between the second support frame and the third flange and the fourth flange.

[0015] In the above design, the welding connection has the characteristics of firm connection, simple implementation process and low implementation cost. The ribs are arranged between the support frame and the flange to enhance the bearing capacity and strengthen the structural strength.

[0016] Furthermore, the aviation obstruction light is a side-mounted aviation obstruction light, and the second support frame is provided with a limiting through groove running through left and right. Two support plates are provided on the side of the side-mounted aviation obstruction light opposite to the light-emitting surface, and limiting holes are provided on the support plates. The second support frame is clamped between the two support plates, and the limiting bolts are passed through the limiting hole of one of the support plates, the limiting through groove on the second support frame, and the limiting hole of the other support plate in sequence. The two ends are then locked and fixed by nuts, so that the support plates are clamped and fixed to the second support frame.

[0017] In the above design, the support plate and the second support frame on the back of the aviation obstruction light are connected and fixed together by bolt connection. The beneficial effect of this connection method is that it has a simple structure and is easy to install. The bolt connection makes the fixation firm and also reduces the manufacturing cost.

[0018] For further optimization, the outer diameter of the second support frame remains unchanged from top to bottom and then gradually increases, and the bottom of the second support frame is provided with a flange extending outward, and the flange serves as the third flange.

[0019] In the above design, the outer diameter of the second support frame remains unchanged from top to bottom and then gradually increases, which has the beneficial effect of providing stable support; the flange extending outward from the bottom of the second support frame is used as a flange, which has the beneficial effect of the integrated flange formed by the flange having higher structural strength.

[0020] Further optimized, there are two groups of limiting grooves, the plane of the upper group is perpendicular to the central axis of the second support frame, and the plane of the lower group is at an acute angle to the central axis of the second support frame.

[0021] In the above design, the beneficial effects of setting up two groups of limit slots are as follows: first, the bolt inserted into the first group of limit slots forms a fixed point, and the bolt inserted into the second group of limit slots forms a second fixed point. The first group of limit slots allows more than one bolt to be inserted, and the second group of limit slots allows more than one bolt to be inserted, so that the support plate has at least two fixed points, which can effectively improve the stability of the aviation obstruction light. Secondly, the bolt inserted into the first group of limit slots can move along the first group of limit slots, and the bolt inserted into the second group of limit slots can move along the second group of limit slots, so that the distance between the two fixed points is adjustable, thereby adapting to aviation obstruction lights of different specifications with different bolt hole distances on the support plate.

[0022] Furthermore, the bottom of the first support frame is connected to a disc-shaped base, the first flange is sleeved on the first support frame, the outer diameter of the base is larger than the inner diameter of the first flange, and the inner diameter of the first flange is larger than the outer diameter of the first support frame; the distance from the first bolt hole to the central axis of the first flange is larger than the distance from the outer edge of the base to the central axis of the base.

[0023] In the above design, the first flange is mounted on the first support frame, and the base prevents the first flange from falling off the first support frame. The first flange can rotate on the first support frame, which has the beneficial effect of facilitating alignment of the bolt holes of the first flange with the bolt holes on the mating steel structure base, facilitating the passage of bolts through the bolt holes and facilitating installation. The distance between the first bolt hole and the central axis of the first flange is greater than the distance between the outer edge of the base and the central axis of the base. This ensures that the outer edge of the base does not hinder the passage of bolts through the bolt holes.

[0024] Furthermore, a strip protrusion extending radially along the base is provided on the upper end surface of the base, the cross-section of the strip protrusion is a right-angled triangle, the strip protrusions are arranged at equal intervals, and form a ring with the center of the base as the center; a strip groove with an opening facing downward is provided on the lower end surface of the first flange, the groove width of the strip groove is not less than the maximum width of the strip protrusion, the number of the strip grooves is the same as the number of the strip protrusions, and the strip grooves are arranged at equal intervals, and form a ring with the center of the first flange as the center.

[0025] In the above design, the beneficial effect is that the positions of the base and the first flange can be limited by the strip-shaped protrusions and the strip-shaped grooves, thereby preventing the base from rotating after being installed in place.

[0026] Furthermore, a groove with a downward opening is provided under the first flange, and the depth of the groove is not less than the thickness of the base. The base is accommodated in the groove, and at least three second ribs in the shape of right-angled triangles are provided between the base and the first support frame. A strip notch is provided on the bottom of the groove to allow the second ribs to extend out; the maximum distance from the strip notch to the center of the first flange is less than the maximum distance from the second rib to the central axis of the second support frame, but greater than the minimum distance from the rib to the central axis of the second support frame, so that the second rib is partially located in the groove and partially extends out of the strip notch.

[0027] The above design has the following advantages: first, the groove can effectively accommodate the base, preventing the base from leaking out and affecting the appearance; second, the strip-shaped notch can limit the position of the ribs, thereby limiting the position of the base, preventing the base from rotating after being installed.

[0028] Furthermore, at least three sixth bolt holes are formed on the first flange and pass through the first flange, and the diameter of the sixth bolt holes is different from the diameter of the first bolt holes.

[0029] In the above design, two sets of bolt holes with different diameters are provided on the first flange. This has the advantage that during installation, either the first or sixth bolt hole can be selected to accommodate steel structure bases with different bolt hole diameters. By selecting both the sixth and first bolt holes, the problem of similar looseness and aging damage caused by bolt holes of a single size can be avoided.

[0030] The steel structure base of the utility model is connected to the curtain wall to adapt to the overall style of the building's facade; the supporting bracket includes a first supporting bracket and a second supporting bracket, the first supporting bracket is flange-connected to the steel structure base, and plays a role of stable and firm support; the second supporting bracket is flange-connected to the first supporting bracket, and the aviation obstruction light is fixed on the second supporting bracket. When the aviation obstruction light needs to adjust its direction, the second supporting bracket can be rotated to achieve the need to adjust the lighting direction of the aviation obstruction light. The design of the first and second supporting brackets has better flexibility.

[0031] The first flange is rotatably mounted on the first support frame, and its beneficial effect is that the first flange can be rotated, which makes it easy to align the bolt holes of the first flange and the bolt holes on the docking steel structure base, making it easy for the bolts to pass through the bolt holes, facilitating installation, improving installation efficiency, and reducing labor consumption.

The aperture of the third bolt hole is the same as that of the second bolt hole. The third flange is connected to the second flange by bolts.

[0046] The aviation obstruction light is fixed on the second support frame 4.

[0047] In this embodiment, the support bracket fixes the aviation obstruction light, and the aviation obstruction light has the need to adjust the direction. The integrated structure of the support bracket is difficult to meet the need to adjust the direction of the aviation obstruction light. Therefore, in this design, the support bracket includes a first support bracket 2 and a second support bracket 4. Its beneficial effect is that the steel structure base 1 is connected to the curtain wall to adapt to the overall style of the building's facade; the first support bracket 2 is flange-connected to the steel structure base 1, playing a role of stable and firm support; the second support bracket 4 is flange-connected to the first support bracket 2, and the aviation obstruction light is fixed on the second support bracket 4. When the aviation obstruction light needs to adjust its direction, rotating the second support bracket 4 can achieve the need for direction adjustment.

[0048] Reference Figure 2 As shown, the aviation obstruction light is a top-mounted aviation obstruction light. A fourth flange is provided on the top of the second support frame 4. The fourth flange is provided with at least three fourth bolt holes extending vertically therethrough. A fifth bolt hole is provided at the bottom of the top-mounted aviation obstruction light at a position corresponding to the fourth bolt hole. The top-mounted aviation obstruction light is fixed to the top of the fourth flange by bolts passing through the fourth and fifth bolt holes.

[0049] In this embodiment, the top-mounted aviation obstruction light is fixed to the second support frame 4 through a flange connection, which has the advantages of simple structure, firm installation and low manufacturing cost.

[0050] Furthermore, the first support frame 2 is welded to the second flange, and the second support frame 4 is welded to the third flange and the fourth flange; a first rib 3 in the shape of a right triangle is provided between the first support frame 2 and the second flange, and between the second support frame 4 and the third flange and the fourth flange.

[0051] In this embodiment, the welding connection has the characteristics of firm connection, simple implementation process and low implementation cost. The rib 3 is provided between the support frame and the flange to enhance the bearing capacity and strengthen the structural strength.

[0052] Reference Figure 1 、 Figure 3 As shown, the aviation obstruction light is a side-mounted aviation obstruction light. A limiting through groove is provided on the second support frame 4, which runs through the left and right sides. Two support plates 5 are provided on the side of the side-mounted aviation obstruction light opposite to the light-emitting surface. The support plates 5 are provided with limiting holes. The second support frame 4 is clamped between the two support plates 5. The limiting bolts 6 pass through the limiting hole of one of the support plates 5, the limiting through groove on the second support frame 4, and the limiting hole of the other support plate 5 in sequence. The two ends are then locked and fixed by nuts, so that the support plates 5 are clamped and fixed to the second support frame 4.

[0053] In this embodiment, the support plate 5 and the second support frame 4 on the back of the aviation obstruction light are connected and fixed together by bolt connection. The beneficial effect of this connection method is that it has a simple structure and is easy to install. The bolt connection ensures firm fixation and reduces manufacturing costs.

[0054] For further optimization, the outer diameter of the second support frame 4 remains unchanged from top to bottom and then gradually increases. The bottom of the second support frame 4 is provided with a flange extending outward, and the flange serves as a third flange.

[0055] In this embodiment, the outer diameter of the second support frame 4 remains unchanged from top to bottom and then gradually increases, which has the beneficial effect of providing a stable support effect; the flange extending outward from the bottom of the second support frame 4 is used as a flange, which has the beneficial effect of the integrated flange formed by the flange having higher structural strength.

[0056] For further optimization, there are two groups of limiting grooves, the plane of the upper group is perpendicular to the central axis of the second support frame 4, and the plane of the lower group is at an acute angle to the central axis of the second support frame 4.

[0057] In this embodiment, the beneficial effects of providing two groups of upper and lower limiting slots are as follows: first, a bolt inserted into the first group of limiting slots forms one fixed point, and a bolt inserted into the second group of limiting slots forms a second fixed point. The first group of limiting slots allows for the insertion of more than one bolt, and the second group of limiting slots allows for the insertion of more than one bolt, so that the support plate 5 has at least two fixed points, which can effectively improve the stability of the aviation obstruction light. Second, the bolt inserted into the first group of limiting slots can move along the first group of limiting slots, and the bolt inserted into the second group of limiting slots can move along the second group of limiting slots, so that the distance between the two fixed points is adjustable, thereby adapting to aviation obstruction lights of different specifications with different bolt hole distances on the support plate 5.

[0058] Reference Figure 4 As shown, the bottom of the first support frame 2 is connected to a disc-shaped base 7, and the first flange 8 is sleeved on the first support frame 2. The outer diameter of the base 7 is larger than the inner diameter of the first flange 8, and the inner diameter of the first flange 8 is larger than the outer diameter of the first support frame 2; the distance from the first bolt hole to the center axis of the first flange 8 is larger than the distance from the outer edge of the base 7 to the center axis of the base 7.

[0059] In this embodiment, the first flange 8 is mounted on the first support frame 2. The base 7 prevents the first flange 8 from falling off the first support frame 2. The first flange 8 can rotate on the first support frame 2. This advantageously allows for easy alignment of the bolt holes of the first flange 8 with the bolt holes on the mating steel structure base 1, facilitating the passage of bolts through the bolt holes and facilitating installation. The distance between the first bolt hole and the central axis of the first flange 8 is greater than the distance between the outer edge of the base 7 and the central axis of the base 7. This ensures that the outer edge of the base 7 does not obstruct the passage of bolts through the bolt holes.

[0060] Furthermore, a strip protrusion extending radially along the base 7 is provided on the upper end surface of the base 7, the cross-section of the strip protrusion is a right-angled triangle, and the strip protrusions are arranged at equal intervals, forming a ring with the center of the base 7 as the center; a strip groove with an opening facing downward is provided on the lower end surface of the first flange 8, the groove width of the strip groove is not less than the maximum width of the strip protrusion, the number of the strip grooves is the same as the number of the strip protrusions, and the strip grooves are arranged at equal intervals, forming a ring with the center of the first flange 8 as the center.

[0061] In this embodiment, the beneficial effect is that the positions of the base 7 and the first flange 8 can be limited by the strip-shaped protrusions and the strip-shaped grooves, thereby preventing the base 7 from rotating after being installed in place.

[0062] Furthermore, a groove with an opening facing downward is provided below the first flange 8, and the depth of the groove is not less than the thickness of the base 7. The base 7 is accommodated in the groove, and at least three second ribs 3 in the shape of right-angled triangles are provided between the base 7 and the first support frame 2. A strip-shaped notch is provided on the bottom of the groove to allow the second ribs 3 to extend out; the maximum distance from the strip-shaped notch to the center of the first flange 8 is less than the maximum distance from the second rib 3 to the central axis of the second support frame 4, but greater than the minimum distance from the rib 3 to the central axis of the second support frame 4, so that the second rib 3 is partially located in the groove and partially extends from the strip-shaped notch.

[0063] In this embodiment, the beneficial effects are as follows: first, the groove can effectively accommodate the base 7, preventing the base 7 from leaking out and affecting the appearance; second, the strip-shaped notch can limit the position of the rib 3, and further limit the position of the base 7, preventing the base 7 from rotating after being installed in place.

[0064] Furthermore, at least three sixth bolt holes are formed on the first flange 8 and pass through the first flange 8 vertically. The diameter of the sixth bolt holes is different from that of the first bolt holes.

[0065] In this embodiment, two sets of bolt holes with different diameters are provided on the first flange 8. This advantageously allows for the selection of either the first or sixth bolt hole during installation to accommodate the steel structure base 1 having different bolt hole diameters. The simultaneous selection of the sixth and first bolt holes can also avoid the problem of similar looseness or aging damage caused by bolt holes of a single size.

[0066] Furthermore, in order to provide a concise description of the exemplary embodiments, all features of the actual embodiment may not be described, i.e., those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention.

[0067] It should be understood that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but for those of ordinary skill having the benefit of this disclosure, the development effort will be a routine task of design, fabrication, and production without undue experimentation.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
