Description
Technical Field
The utility model belongs to the technical field of photovoltaic supports of photovoltaic power stations, and particularly relates to a connecting piece for a photovoltaic support.
Background
In a photovoltaic power station, a photovoltaic module is called as a module for realizing photoelectric conversion, a photovoltaic support is a steel support for supporting the photovoltaic module, and the photovoltaic support is generally arranged in open air on a wide open field. Photovoltaic brackets are generally divided into fixed brackets, fixed adjustable brackets, and tracking brackets.
The fixed photovoltaic support is generally divided into a single-upright photovoltaic support and a double-upright photovoltaic support, and is the most commonly used photovoltaic support with wide application.
The double-upright-column photovoltaic support is in the earliest adopted photovoltaic support form, has the advantages of good stability, small steel consumption, simple and convenient construction and optimal economy. The double-upright-column photovoltaic bracket consists of purlines, inclined beams, round steel cross supports, double upright columns, a group of herringbone inclined struts and round steel cross column supports, wherein the purlines, the inclined beams and the round steel cross supports are tensioned among the inclined beams, and the round steel cross column supports are tensioned on the side of a higher upright column of the longitudinal double upright columns. When calculating the sloping of the double-column photovoltaic support, the upper flange of the double-column photovoltaic support is limited by purlines and purline supports, and the calculation length of the double-column photovoltaic support can generally select the distance between the purlines. For the lower flange of the oblique beam, the calculated length of the lower flange is actually the distance between two upright posts due to the capability of transmitting longitudinal horizontal force of only the double upright posts, and the lower flange is used as a thin-wall curled channel steel with extremely small steel consumption. If the purline is used as a support to forcibly reduce the calculated length only because the height of the oblique beam is not large, the potential use risk is obviously caused. For example, for a thin-wall curled channel purline with the same height, the upper part of the purline is provided with the top rigidity formed by a full-spread assembly which is more effective than an inclined beam, and the purline is used as a secondary beam, and the lower flange still needs to be formed by an effective system formed by purlines, stay bars and the like, so that the calculation length can be reduced. According to the arrangement of the photovoltaic support, if an effective support system is to be formed on the lower flange of the oblique beam, an effective pressure force transmission system must be provided in addition to the cross tie, which is obviously costly and difficult to realize. The diagonal girder as a main girder is obviously unsuitable and not compliant with the specification if the actual supporting condition of the lower flange is completely ignored and the calculated length of the lower flange is forcibly reduced according to the top purline.
The single upright post is also an earliest fixed photovoltaic bracket form, and the specific gravity of the single upright post in the fixed bracket is higher and higher along with the recent significant horse-feeding of agricultural light complementation, forest light complementation and fishing light complementation projects. The single-upright-column photovoltaic bracket consists of purlines, inclined beams and round steel cross supports and single upright columns, wherein the purlines, the inclined beams and the round steel cross supports are tensioned among the inclined beams, and the purlines, the inclined beams and the round steel cross supports are directly used for supporting the photovoltaic modules. The calculated length of the upper flange of the inclined beam of the single-upright photovoltaic support is identical to that of the upper flange of the double-upright photovoltaic support. The lower flange of the vertical force transmission pillar is only provided with a single middle upright post, and the calculated length of the lower flange out of the plane is about twice of the half of the oblique beam, namely about the actual length of the oblique beam, according to the cantilever length from the pillar to the beam edge. The actual calculation length of the lower flange is larger than that of the double upright posts, and if the lower flange is selected according to actual conditions, larger steel consumption is caused. Similar to the double column case, the lower flanges are difficult to form into an effective support system, and the risk of instability is greater if the actual support situation is ignored.
When the fixed adjustable basic structure is arranged in the same structure form as the fixed bracket, the inclined beam has the problem that the inclined beam is basically consistent with the fixed bracket.
