Description

Technical Field

[0001] The utility model relates to the field of solar photovoltaic assembly installation, in particular to a photovoltaic foundation bracket for a prefabricated hollow slab roof. Background Art

[0002] At present, many household houses are built 20 to 30 years ago. The roofs are in good condition and have a large free area, but the roofs are relatively old. The roof panels are prefabricated hollow slabs and cannot be used as load-bearing components of photovoltaic foundations. At present, the roof photovoltaic brackets are mostly fixed in cement piers and expansion bolts, which can be regarded as node loads. The concentrated load of cement piers is large, and the expansion bolts are not firmly fixed in the prefabricated hollow slabs, which are not suitable for this roof form. Now there is a need for a bracket foundation that can be combined with this roof structure to effectively transfer photovoltaic loads to solve the current problems related to photovoltaic installation on the roofs of household houses. Utility Model Content

[0003] The utility model aims to provide a photovoltaic base support for a prefabricated hollow slab roof to solve the problems in the prior art.

[0004] A photovoltaic foundation support for a prefabricated hollow slab roof comprises a base, one end of the base is fixedly connected to a strip foundation, the strip foundation is prefabricated or cast, the strip foundation is straddled on a brick wall, and both ends of the strip foundation are respectively placed on a load-bearing brick wall. The load of the entire photovoltaic system is directly transmitted to the load-bearing brick wall through the foundation support, and then transmitted to the foundation of the house, so that the stress on the foundation of the house is more uniform and safer. The other end of the base is connected to an inclined beam through a column, and the inclined beam is connected to a solar photovoltaic module through a purlin.

[0005] The base is fixedly connected to the strip foundation via a connecting plate and bolts, and the upright column is sleeved with the base and fixed via bolts.

[0006] At least two columns are provided, and the two columns include a first column and a second column. The first column is connected to one end of the inclined beam, and the second column is connected to the other end of the inclined beam. The first column and the second column are respectively connected to the head end and the end of the inclined beam to provide support for the inclined beam.

[0007] There are three columns, including a first column, a second column and a third column. The first column is connected to one end of the inclined beam, the second column is connected to the other end of the inclined beam, and the third column is connected to the middle of the inclined beam. The weight load of the solar photovoltaic module is decomposed to the strip foundation connected to the columns through the first column, the second column and the third column, so that the load distribution is more uniform.

[0008] The column is connected to the inclined beam through a triangular connector, the column is rotatably connected to one corner of the triangular connector by a bolt, the other two corners of the triangular connector are connected to the inclined beam through a screw, and the column is connected to the inclined beam through the triangular connector. During the installation process, after the column is vertically fixed, the triangular connector facilitates the adjustment of the installation angle of the inclined beam, which is convenient for installing other columns.

[0009] A diagonal brace is provided between the second column and the third column, one end of the diagonal brace is connected to the column on the base through a triangular connector, and the other end is connected to the diagonal beam through a triangular connector. The diagonal beam between the second column and the third column lacks a middle support, and one end of the diagonal brace is connected to the middle of the diagonal beam between the second column and the third column, and the other end is connected to the second column, so as to construct a triangular structure, so that the support of the diagonal beam is more stable.

[0010] The solar photovoltaic components are provided in two groups, and the two groups of photovoltaic components are arranged on the inclined beams through purlins.

[0011] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0012] 1. Good stability: The strip foundation has a larger contact area, which can more evenly disperse the load of the photovoltaic support bracket and improve the stability of the entire photovoltaic support system;

[0013] 2. High bearing capacity: Strip foundation can bear large vertical and horizontal loads;

[0014] 3. Convenient construction: The construction of strip foundation is relatively simple, and can be prefabricated or cast-in-place, with a short construction period and high efficiency;

[0015] 4. Simple load transfer: Both ends of the strip foundation are placed on the load-bearing walls respectively. The load of the entire photovoltaic system is transferred to the strip foundation through the columns, then to the load-bearing wall, and then to the foundation of the house, making the force more uniform and safer.

Figure 2 As shown, the strip foundation 8 is in the shape of a long strip and can be prefabricated or cast, with a short construction period. The other end of the base 7 is connected to the inclined beam 3 through a column, and the inclined beam 3 is connected to the solar photovoltaic module 1 through the purlin 2.

[0022] The base 7 is fixedly connected to the strip foundation 8 via a connecting plate 7.1 and bolts, and the column is sleeved with the base and fixed via bolts.

[0023] At least two columns are provided, and the two columns include a first column 5.1 and a second column 5.2. The first column 5.1 is connected to one end of the inclined beam 3, and the second column 5.2 is connected to the other end of the inclined beam 3. The first column 5.1 supports the head end of the inclined beam 3, and the second column 5.2 supports the end of the inclined beam 3. The first column 5.1 and the second column 5.2 complete the support of the head and the end of the inclined beam 3.

[0024] The column is connected to the inclined beam 3 through a triangular connector 4, and the column is connected to one corner of the triangular connector 4 by rotation through bolts. The other two corners of the triangular connector 4 are connected to the inclined beam 3 through screws. The triangular connectors connected to the inclined beam 3 are fixed at two corners by screws, and the other corner is connected to the column by bolts. The column is connected to the triangular connector at only one point, which is convenient for adjusting the installation angle during installation.

[0025] Two groups of solar photovoltaic components 1 are provided, and the two groups of solar photovoltaic components 1 are arranged on the inclined beams 3 through purlins 2.
