Photovoltaic support column base for saddle plate roof

Abstract

The invention discloses a photovoltaic support column foot for a saddle plate roof. The photovoltaic support column foot is characterized in that a saddle plate (1) is provided with a column foot through hole matched with a column foot bottom plate (3); the column foot bottom plate (3) is fixedly arranged in the column foot through hole; an oblique notch is formed in the lower end of the column bottom sleeve (4), the lower end of the column bottom sleeve (4) is fixedly arranged on the column foot bottom plate (3), and the axis of the column bottom sleeve (4) is parallel to the plumb line direction; the lower end of the stand column is slidably arranged in a column bottom sleeve (4). The photovoltaic support (9) is fixedly installed on the stand column. The multiple fixing bolts are arranged on the stand columns, the length of the stand columns extending into the column bottom sleeves is adjustable, it is guaranteed that the relative elevation of the top faces of the multiple stand columns is not changed, and then it is guaranteed that the dip angle of the photovoltaic support is not changed; according to the device, the cement-based grouting material is poured below the column base bottom plate, and the chemical anchor bolt nut is tightened after the cement-based grouting material reaches the strength, so that the perpendicularity of the photovoltaic bracket upright column is ensured, and the smooth installation of the photovoltaic bracket is further ensured.

Description

technical field [0001] The invention relates to a column foot of a photovoltaic support used for a saddle board roof, and belongs to the technical field of photovoltaic support. Background technique [0002] When installing photovoltaic brackets on the saddle roof, because the saddle roof is curved, it is difficult to connect the column foot and the roof. Generally, expansion bolts are used to fix it, but the strength of the expansion bolts is low, and the structural safety is poor. And the thickness of the saddle plate is relatively thin, and there is no condition for arranging connecting parts at its top position. The saddle board also has the function of drainage in the longitudinal direction, that is, there is a certain slope in the longitudinal direction of the saddle board, and the lowest point of the saddle board is the rainwater drainage route, so it is obviously inappropriate to arrange connectors at the lowest point. In addition, the roof photovoltaic brackets are...

[0002] When installing photovoltaic brackets on the saddle roof, because the saddle roof is curved, it is difficult to connect the column foot and the roof. Generally, expansion bolts are used to fix it, but the strength of the expansion bolts is low, and the structural safety is poor.

Moreover, the thickness of the saddle board is relatively thin, and there is no condition for arranging connecting parts at its top position

The saddle board also has the function of drainage in the longitudinal direction, that is, there is a certain slope in the longitudinal direction of the saddle board, and the lowest point of the saddle board is the rainwater drainage route. It is obviously inappropriate to arrange connectors at the lowest point

In addition, the roof photovoltaic brackets are generally arranged with front and rear columns. When the straight line direction of the front and rear columns is parallel to the longitudinal axis of the saddle board, the elevation of the feet of the front and rear columns is very easy. Inconsistent, in order to ensure the verticality of the columns of the photovoltaic support, this also increases the difficulty of the design of this type of photovoltaic support
