Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic facility foundations, in particular to a roof photovoltaic combined strip foundation. Background Art

[0002] Rooftop photovoltaic projects refer to the installation of photovoltaic power generation systems on the roofs of buildings. Building roofs can be divided into color steel plate roofs, concrete flat roofs and concrete sloping roofs. For color steel plate roofs and concrete sloping roofs, photovoltaic modules can be directly connected to the building roofs through special aluminum alloy rails. This connection method imposes less additional load on the building roofs, and the buildings can often meet the corresponding load requirements. For concrete flat roofs, in order to increase the power generation of the photovoltaic system, photovoltaic modules are often arranged with an angle. Therefore, it is impossible to use special aluminum alloy rails to directly connect to the building roof. Instead, they need to be fixed through photovoltaic brackets similar to the ground, and the photovoltaic brackets need to be fixed to the building roof through a newly built bracket foundation.

[0003] At present, in the construction of such rooftop photovoltaic projects, the photovoltaic support foundation mostly uses concrete counterweights. Using this technical solution, 0.65KN / m 2 For existing buildings whose roofs are not designed as human-friendly roofs, the above-mentioned additional loads cannot meet the requirements of the additional photovoltaic loads as the design bearing capacity of the original building roof panels cannot, thus limiting the construction of roof photovoltaic projects. Utility Model Content

[0004] The utility model overcomes the shortcomings of the prior art and provides a roof photovoltaic combined strip foundation.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions.

[0006] A roof photovoltaic combined strip foundation comprises channel steel and a concrete foundation, wherein the channel steel is arranged along the load-bearing wall of a building, and a concrete foundation is poured outside the channel steel; the channel steel is vertically connected to a roof beam of a roof through a first anchor bolt; the channel steel and a concrete foundation bracket are vertically connected through a second anchor bolt, and the second anchor bolt extends out of the top of the concrete foundation; two channel steels at an intersection are arranged up and down, and the roof beam and the intersection of the two channel steels are vertically connected around through a third anchor bolt; the third anchor bolt extends out of the top of the concrete foundation.

[0007] Furthermore, the second anchor bolts are arranged around the intersection of the two channel steels.

[0008] Furthermore, the second anchor bolts and the third anchor bolts are arranged alternately.

[0009] Furthermore, the top of the first anchor bolt extends out of the channel steel and is located in the concrete foundation at the same time.

[0010] Furthermore, the first anchor bolts are arranged at intervals along the channel steel.

[0011] The beneficial effects of the utility model compared with the prior art are:

[0012] The utility model is for the roof of an existing building whose roof structure is a concrete flat roof. By newly building a reinforced concrete combined strip foundation along the wall of the existing building, the load of the newly built photovoltaic power generation on the roof is transmitted to the wall of the original building with higher bearing capacity through the newly built reinforced concrete combined strip foundation, avoiding additional load on the roof panel with poor bearing capacity, thereby realizing the construction of roof photovoltaic power generation on the roof of an existing building with poor bearing capacity of the roof panel.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail in combination with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0020] See also Figure 1-4The present embodiment proposes a roof photovoltaic combined strip foundation, comprising a channel steel 1 and a concrete foundation 2, wherein the channel steel 1 is arranged along a load-bearing wall 9 of a building, and a concrete foundation 2 is cast outside the channel steel 1; the channel steel 1 is vertically connected to a roof beam 4 of a roof through a first anchor bolt 3; a prefabricated plate 5 is provided above the roof beam 4; the channel steel 1 and the concrete foundation 2 are vertically connected through a second anchor bolt 6, and the second anchor bolt 6 extends out of the top of the concrete foundation 2; two channel steels 1 at an intersection 7 are arranged up and down, and the roof beam 4 and the intersection 7 of the two channel steels 1 are vertically connected around through a third anchor bolt 8; the third anchor bolt 8 extends out of the top of the concrete foundation 2.

[0021] The second anchor bolts 6 are arranged around the intersection 7 of the two channel steels 1 .

[0022] The second anchor bolts 6 and the third anchor bolts 8 are arranged alternately.

[0023] The top of the first anchor bolt 3 extends out of the channel steel 1 and is located in the concrete foundation 2 at the same time.

[0024] The first anchor bolts 3 are arranged at intervals along the channel steel 1 .

[0025] The support foundation is arranged along the wall with higher bearing capacity of the existing building. The load generated by the new photovoltaic on the roof is transmitted to the wall with higher bearing capacity of the original building through the reinforced concrete joint strip foundation, avoiding additional load on the roof panel with poor bearing capacity. The reinforced concrete joint strip foundation mainly relies on its own weight and structural integrity to meet the load transmitted by the upper photovoltaic support structure. When the self-weight of the reinforced concrete joint strip foundation cannot meet the bearing capacity requirements of the upper structure, the bearing capacity of the foundation can be increased by planting reinforcement with the wall of the existing building to meet the bearing capacity requirements of the upper structure. Specific implementation method:

[0027] 1. Determine the location and bearing capacity of the walls of existing buildings;

[0028] 2. Construct reinforced concrete combined strip foundation on the wall whose bearing capacity can meet the relevant requirements;

[0029] 3. The photovoltaic bracket is connected to the newly built reinforced concrete joint strip foundation through the foundation embedded parts;

[0030] 4. The load generated by the newly added photovoltaic power generation is connected to the walls of the original building with a higher bearing capacity through a newly built reinforced concrete joint strip foundation, effectively avoiding additional loads on the roof panels with poor bearing capacity.

[0031] The above content is a further detailed description of the utility model in combination with a specific preferred implementation method. It cannot be determined that the specific implementation methods of the utility model are limited to this. For ordinary technicians in the technical field to which the utility model belongs, they can make several simple deductions or substitutions without departing from the utility model, which should be regarded as belonging to the utility model and the scope of patent protection determined by the submitted claims.
