Description

Be applied to light production well structure of basement roof

Technical Field

The utility model relates to a lighting well structure, especially a be applied to lighting well structure of basement roof.

Background

With the economic development, the automobile holding capacity of the modern society is greatly increased, and the increasingly severe parking problem draws attention, and particularly in urban areas with precious soil, a large number of underground garages are built in various places for greening and parking. The top plate of the underground garage is covered with soil, green plants and the like are planted on the top plate, the underground garage can be used as a place for people to move and rest, and the underground garage can be parked to bring out the best in each other.

The underground garage is a relatively closed space, and lighting is a problem which must be considered, and the common method comprises the following steps of utilizing an artificial light source to illuminate for 24 hours without interruption, but having high energy consumption and being uneconomical; in addition, a lighting well is arranged on a top plate of the basement, natural light is used for lighting in the daytime, an artificial light source is used for lighting at night, or solar lamps are used for lighting by solar energy stored in the daytime, and the method is relatively economical and also accords with the green building idea advocated at present.

As is well known, the outdoor pipe network and the planting requirements are considered, the basement roof is usually covered with thick soil, most of the soil is more than 1.5 meters especially in the area with large northern frozen soil depth, the lighting well of the basement roof is difficult to open at the moment, and the influence degree of the lighting well on the integrity of the basement roof is directly related to the size of the lighting well. The sunlight is incident to the basement and needs to pass through the distance of 1.5 m plus the thickness of the top plate of the underground chamber, the opening of the lighting well is too small, and the sunlight is shielded by the side wall of the lighting well and cannot take the lighting effect; the too big of opening then destroys great to basement roof wholeness, needs add the roof beam component at the light production well entrance to a cave periphery, influences the structure specialty and arranges, and can reduce the floor height, influences the equipment pipeline.

Therefore, the design of a light production well structure can give consideration to structural integrity and arrangement convenience, and can introduce sunlight into an underground space to the greatest extent, which is a problem to be solved urgently.

Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:

referring to fig. 1 and 2, a lighting well structure applied to a basement roof is arranged in a column network formed by enclosing frame columns 1 and frame beams 2, generally arranged in the middle and comprises an underground part and an overground part, wherein the underground part comprises a quadrangular frustum pyramid type concrete well wall 3, the upper end of the concrete well wall 3 is provided with a reinforcing beam 4, and the lower end of the concrete well wall is supported by the frame beams 2; the above-ground part comprises a waterproof reverse ridge 5 arranged on the reinforcing beam 4, a stand column 7 is fixed on the waterproof reverse ridge 5, a cross beam 8 is supported on the stand column 7, a light-transmitting plate 10 is supported on the cross beam 8, and a rainproof ventilation structure 6 is sealed between the light-transmitting plate 10 and the waterproof reverse ridge 5.

In this embodiment, it is recommended that the waterproof reverse ridge 5 is 0.5-0.8 m higher than the ground, so as to prevent the ground ponding from flowing backwards. The upright post 7 is connected with the waterproof reverse sill 5 through an embedded part 9 arranged in the waterproof reverse sill 5, and is firm and reliable. The light-transmitting plate 10 adopts a slope finding structure, is beneficial to water drainage, can be in the form of two slopes, a single slope, four slopes and the like, and can be adjusted according to the requirements of building landscapes. The light-transmitting plate 10 is usually a glass plate, and may be replaced with a light-transmitting material of other materials. The rain-proof ventilation structure 6 is a rain-proof ventilation shutter, and other parts with rain-proof ventilation function can be adopted. The inclination angle theta of the concrete well wall 3 is not less than the minimum value of the solar altitude angle of the location of the structure and not less than 30 degrees, and when the inclination angle of the well wall is matched with the solar altitude angle, sunlight 12 can be guided into the well wall to the greatest extent. Meanwhile, the optimal size of the opening of the lighting well can be determined by considering the factors of the thickness of the covering soil. The upright posts 7 and the cross beams 8 can be made of steel, aluminum alloy, stainless steel and other light high-strength materials. The lighting well opening can be arranged in the center of the column net, and can also be arranged in the non-center according to the building requirements. The lighting well opening can be rectangular, circular, polygonal and the like, and can be adjusted according to the requirements of building landscapes.

The lighting well adopts the quadrangular frustum pyramid type concrete well wall to reduce the thickness of the top plate earthing 11, fully utilizes the good compression characteristic of concrete materials, can sufficiently enlarge the opening of the hole, avoids the problem that the periphery of the hole and the column need to be additionally arranged to span the same-length concrete beam when the well wall is vertically arranged, and saves materials. In addition, when the inclination angle theta of the well wall is matched with the solar altitude at the position of the structure, sunlight 12 can be guided into the basement to the greatest extent, the blocking of the side wall of the conventional lighting well to incident light is avoided, the lighting efficiency of the lighting well can be greatly improved, the lighting influence range of one lighting well is increased, and the arrangement number of the lighting wells of the underground garage is reduced. The arrangement of the peripheral rain-proof ventilation structure 6 ensures that the basement airflow 13 is fully exchanged with the outdoor space, can improve the air quality of the underground space, and is convenient for building a comfortable underground space.

Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, which is within the scope of the present invention.
