Background

This is currently the state of the art commonly used in the industry.

Prefabricating a concrete strip foundation (or a concrete block) on site, connecting the prefabricated concrete strip foundation with a roof through expansion bolts, and then performing water proofing again at the position where the expansion bolts are arranged on the roof; and the photovoltaic support foundation is balanced by mass concrete, so that the connection between the photovoltaic support foundation and the roof is ensured.

The existing roof support has the following basic defects:

1. the foundation takes root, the expansion bolt is used for connecting the roof and the foundation, the water resistance of the roof is damaged, and the roof is easy to leak when the treatment is not good;

2. the construction is complicated, a large amount of manpower is needed on the site, and the construction is not economical;

3. the large-size foundation easily damages the original roof drainage channel, so that the roof drainage is difficult;

4. often, due to the limitation of field conditions, the engineering quality is difficult to ensure;

5. the uplift resistance of the foundation is ensured through the balance weight, and the roof load is increased;

in summary, the problems of the prior art are as follows:

(1) the expansion bolts are adopted for connecting the roof and the foundation, so that the water resistance of the roof is easy to damage, the water-proof treatment is needed, and the roof is easy to leak when the treatment is not good.

(2) The waterproof is reworked, the concrete foundation is manufactured on site, the construction is complicated, a large amount of manpower is needed on site, and the method is not economical.

(3) The original roof drainage channel is easy to damage, so that the roof drainage is difficult.

(4) Due to the limitation of field conditions, it is difficult to ensure the quality of the concrete foundation.

(5) The load of the roof is increased more.

The difficulty in solving the technical problems is as follows:

the stress of the photovoltaic support foundation is guaranteed, the waterproof performance is not damaged, and the weight of the foundation is reduced as much as possible.

The significance of solving the technical problems is as follows:

with the rapid development of the photovoltaic industry, the market needs to use the existing building roof to arrange the photovoltaic panels, arrange the photovoltaic panels on the existing building roof, and need a system which can meet the stress requirement of the photovoltaic support foundation, keep the original waterproof and drainage system of the roof as much as possible, and reduce the load increased by the roof as much as possible.

Disclosure of Invention

To the problem that prior art exists, the utility model provides a roofing photovoltaic support.

The utility model is realized in such a way that the photovoltaic bracket of the roof is provided with a concrete block;

the U-shaped foundation bolt is embedded in the concrete block;

the steel plate is sleeved on the U-shaped foundation bolt;

and the nut is spirally sleeved on the U-shaped foundation bolt on the outer side of the steel plate.

The concrete block foundation is manufactured by a factory, the mixing ratio of the concrete blocks can be controlled, the strength of the concrete blocks is ensured, and the concrete blocks are maintained; the embedded part consisting of the U-shaped foundation bolt and the steel plate can be accurately positioned and poured in the concrete block body, so that the size of the concrete block body can be accurately controlled, and the quality of a finished product is ensured; the construction is completed in a factory, so that the construction speed is high, the labor cost is saved, the environment is protected, and the construction method is safe, economical and reasonable; the concrete block foundation is built on the roof, so that the original roof is kept waterproof, and the roof leakage is avoided; because the concrete block foundation has small cross-sectional area, the original roof drainage waterway is not influenced through reasonable arrangement, and the smooth roof drainage is ensured.

Furthermore, a mortar layer is poured between the concrete block and the roof panel.

The concrete block is built on the roof through the mortar layer, the tensile bearing capacity of the concrete block is improved by using the adhesive force of the mortar layer, the weight of the concrete block can be reduced under the same condition, and the weight increment of the roof is reduced.

Another object of the utility model is to provide an install photovoltaic power generation device on roofing photovoltaic support basis.
