Technical Field

The utility model relates to a window structure field especially relates to a daylighting structure that is used for reflection of light unit in skylight and has utilized this reflection of light unit.

Background

With the rapid construction of high-speed rail passenger stations in China, the relationship between the appearance of the stations and the functional streamline has long-standing optimization and development. The use of the skylight of the station hall is quite common by combining the operation cost of the station and environmental protection and energy conservation. In the design of a station house in the past, a skylight is generally designed by combining a steel structure roof and can be divided into a centralized skylight and a strip-shaped skylight. Due to the combination of the fire-fighting rehearsal function, the opening mode can be divided into a flat opening mode and a side opening mode. The existing skylight for the railway station house has strong functionality, is single in structure, is straight up and straight down, and does not consider the problems of excessive incident angles, light reflection, excessive flow increase and the like. For example, the high-speed rail station in the great wall of octada is located in the scenic spot of the great wall of octada, and the main functions of the station are placed underground in order to protect the natural landscape and the human landscape on the ground to the maximum extent. The ground only keeps the functions of entering and leaving stations, waiting and working. The main platform and technical room are placed under the ground for minus 102 meters. The two are connected by a diagonal passage. Because the large-area space of the station room is underground, the introduction of natural light and the light comfort level are particularly important, and the feeling of oppression of passengers is avoided.

Patent CN205894436U discloses a suspended ceiling structure, in which a skylight is composed of two arc-shaped supporting rods and a glass fiber gypsum board supported by the two supporting rods. The area surrounded by the glass fiber gypsum board is the lighting channel. Because the supporting rod is arc-shaped, the lighting channel naturally extends along the arc to form a wide mouth. It can be seen that the skylight of this patent initially realizes the function of increasing the light overflowing amount by using a wide-mouth design. However, due to the design of the arc-shaped lighting channel, the reflection of the light by the glass fiber gypsum board is relatively divergent, and the light cannot be guided in a concentrated and accurate manner, so that the light cannot be accurately irradiated to areas which are deep and difficult to be irradiated by the light, such as an inclined passage (escalator) in a station.

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, which are not repeated herein, but the present invention is not limited to the following embodiments.

Fig. 1 is a cross-sectional view schematically showing a lighting structure according to an embodiment of the present invention in an installation state, and as can be seen from fig. 1, the installation state of the present invention refers to a state in which the lighting structure is installed in a sunroof. Fig. 2 is a view showing the overall lighting effect of a skylight to which the lighting structure of the present invention is applied. Fig. 3 shows a light reflection effect diagram of the skylight with the lighting structure of the present invention, which aims to show the path of light reflected by the lighting structure. As shown in fig. 1, the utility model discloses a daylighting structure meets in proper order and forms the tube-shape by a plurality of reflection of light unit circumference, including support 1, reflecting plate 2 and mounting 3 in every reflection of light unit, and support 1 comprises the frame that horizontal pole and the vertical pole that intercrossing set up constitute, and reflecting plate 2 and mounting 3 then are located the both sides of the frame of constituteing support 1 respectively. Since the main functions of the bracket 1 are to mount the reflection plate 2 and to fix the mounting angle thereof, the bracket 1 in the present embodiment is a single-layer light steel keel frame in order to reduce the weight of the bracket 1. The reflecting plate 2 is laid on the bracket 1 and can be used as a reflecting medium of light, and the fixing piece 3 is connected with the bracket 1 and is used for supporting the reflecting unit. The utility model discloses in, two-layer reflecting plate 2 is laid to each position, utilizes two-layer reflecting plate 2 to laminate each other promptly and constitutes a whole board, can improve intensity from this. Thus, when the bracket 1 is attached to the sunroof in an inclined manner as shown in fig. 1, the lower end of the reflection plate 2 is also inclined. The width of the lower end of the lighting structure is larger than that of the upper end, and the lighting effect graph shown in fig. 2 can be used for increasing the light throughput (or light inlet area) so as to improve the overall brightness in the station. In order to form the whole lighting structure into a cylinder shape so as to form a lighting channel, the number of the light reflecting units is more than three. In this embodiment, four light reflecting units are provided, so that the lighting structure forms a quadrangular frustum-shaped tube. In addition, the reflecting plate 2 is a rectangular flat plate, so that the extending path of the lighting channel is a straight line, and the reflected light of the reflecting plate 2 is not diffused in this way, so that the light can be guided more accurately. Referring to fig. 3, after the light irradiated on the reflection plate 2 is reflected, the light is precisely irradiated to an inclined passage area (i.e., an escalator area) where the light is not easily irradiated. The utility model discloses in, the material of reflecting plate 2 is calcium silicate, and it is installed on support 1 through self-tapping screw, can be so that light is soft and not dazzling.

The utility model discloses in, in the skylight opening was installed to the mode that the daylighting structure wholly adopted hoist and mount, consequently still set up hoist and mount pole 4 in the daylighting unit. One end of the hoisting rod 4 is connected with the bottom of the bracket 1, and the other end is connected with the wall in the skylight opening. Referring to fig. 1, the lower end of the hoisting rod 4 is connected with a hanging piece a, and the bottom of the bracket 1 of the utility model is connected with a keel system, so the hanging piece a in the embodiment is arranged on the keel system. Because the hoisting point of the lighting structure is positioned at the bottom end of the lighting structure, the upper end of the lighting structure is easy to incline or shake, and the fixed part 3 can support the light reflecting unit at the upper end, so that the problem is solved. The main body of the fixing member 3 is a support rod 3a, and one end of the support rod 3a is provided with a mounting plate 3 b. The fixing pieces 3 are all located on the outer side of the lighting structure, one end of the supporting rod 3a far away from the mounting plate 3b is fixedly connected to the support 1 (for example, in a fixing mode such as a tapping screw), and the mounting plate 3b is fixedly connected to the inner wall of the skylight opening through a screw. In order to make the support 1 be the tilt state after installing on the skylight, the utility model discloses a mounting 3 is connected with support 1 slope. Namely, the angle between the supporting rod 3a of the fixing piece 3 and the bracket 1 is less than 90 degrees, so that the bracket 1 can be in an inclined state after the supporting rod is horizontally installed in the skylight opening. In this embodiment, the middle and the end of the bracket 1 are respectively connected to a fixing member 3, so that the two fixing members 3 are separated and parallel to each other, thereby stably supporting the whole lighting structure. Of course, the number of the fixing members 3 may be set according to the actual situation, but at least two are set as described above.

As can be seen from fig. 1, the fixing member 3 is installed horizontally, so the inclination angle of the reflection plate 2 in the installation state is mainly determined by the included angle between the bracket 1 and the supporting rod 3a of the fixing member 3, and if the inclination angle of the reflection plate 2 is too large, more light rays are reflected to the ground, so that the amount of light rays reflected to the inclined passage is less, which is not beneficial to increasing brightness to the dim inclined passage; if the inclination angle is too small, the angle between the reflected light and the horizontal plane is too small to reach the inclined passage. In this embodiment, the bracket 1 is at an angle of 78 ° to the support bar 3a of the mount 3. Referring to fig. 4, the reflecting plate 2 is inclined at an angle of 78 ° according to the solar altitude 26.5 of the winter solstice day in the beijing area, so that the light can be ensured to extend into the tunnel through reflection. Compare the reflection path in the vertical plate in fig. 4, the utility model discloses can guarantee station room and tunnel of leaving a station winter, it is indoor that more light gets into to have when the sun altitude angle is lower. In addition, in the installed state, the size of the bracket 1 in the vertical direction and the diameter of the inscribed circle of the shape surrounded by the upper end also affect the lighting effect of the whole lighting structure. As can be seen from the light reflection diagram shown in fig. 3, if the size of the support 1 in the vertical direction is too large, the light will be reflected back and forth between the reflective plates 2, so that most of the energy of the light will be absorbed by the reflective plates 2, and the light intensity transmitted to the station will be reduced; if the size in the vertical direction is too small, the amount of light irradiated on the reflection plate 2 is too small, so that most of the light is irradiated into the station without being reflected, and the effect of increasing the light flux by the wide-mouth form of the light-collecting passage is not large. Therefore, in the present invention, the size of the bracket 1 in the vertical direction after being installed is 1200 mm. For a general skylight design, it is necessary to avoid the dim indoor due to too small amount of incoming light, and avoid the glare due to too high amount of incoming light. Therefore, in the installation state, the diameter of the inscribed circle of the shape surrounded by the upper end (namely the area with the minimum width) of the lighting structure is 1200mm, and therefore reasonable lighting of the skylight is achieved.

As shown in fig. 1, the upper end of the reflector 2 is spaced from the top window glass, which also prevents all light entering the window from entering the light collecting channel formed by the reflector 2. In order to gather together the light that gets into the window from window top printing opacity glass, the utility model discloses a support 1 upper end extends towards the 3 place inclines in one side of mounting, forms an extension section. In the installation state, this extension is vertical state for the upper end of whole daylighting structure forms a straight section of thick bamboo. And because the support 1 builds the hollow out construction that forms for having the fossil fragments, consequently in order to cooperate the upper end extension section of support 1 to realize holding together the light function, the upper end of reflecting plate 2 also is towards the one side bending at mounting 3 places, has formed a bending segment, can shelter from the inboard at the upper end extension section of support 1 after the installation, has realized the effect of gathering together light from this. As can be seen from figure 1, the utility model provides a lighting structure's hoist and mount portion is located the lower extreme of support 1, and consequently the lower extreme of support 1 also extends towards mounting 3 place lopsidedness, forms another extension section, meets as the downside of hoist and mount position with the fossil fragments system to indirect and hoist and mount pole 4 is connected. Thus, in another embodiment, if the extension section is located above the keel system after the bracket 1 is installed, the hanging member a may be provided on the extension section so that the hanging portion of the bracket 1 is directly connected to the hanging rod 4. The utility model discloses in, this extension is basically parallel with the horizontal plane under the mounted state. Since this extension is part of the support 1, it is also made of light gauge steel, with its underside facing directly into the station, and in order to avoid light reflections, the lower end of the reflector plate 2 is also bent towards the side where the fixture 3 is located, forming another bend. The bending section is vertical to the upper end bending section, and after the reflecting plate 2 is arranged on the support 1, the lower end bending section is just positioned below the hoisting part of the support 1, so that the reflecting plate is shielded. Therefore, the utility model provides an upper and lower both ends of reflecting plate 2 possess two to buckling and mutually perpendicular's the bending segment with one side, the structure of integral type not only can accomplish the effect of sheltering from and gathering together light like this, still is convenient for process and equipment.
