Description
Technical field
The utility model relates to and is a kind ofly applicable to the simple and easy strip foundation of photovoltaic module fixed bracket in solar earth photovoltaic plant structure is set.
Background technology
In solar earth photovoltaic plant, photovoltaic module fixed bracket basis mainly contains following several at present: 1, single footing; 2, conventional strip basis; 3, spiral steel pile foundation.Its structure respectively as Figure 1-3.General, except spiral piling bar adopts Q235B steel, other basic materials all adopt concrete and rebar.
By cases of engineering, finding, there are some problems in above basis separately.Specifically as shown in table 1.
Table 1
As shown in Figure 4, for the basic structural plan arrangement schematic diagram being connected of existing photovoltaic module support and conventional strip, it is in the drawings for arranging from top to bottom two grade beams 2, the front column 31 of photovoltaic module support is located at a grade beam above, and rear column 32 is arranged at a grade beam below, very large (the 20000mm left and right of this grade beam entire length, or more than), if the right and left landform is variant, it arranges more difficult, and the scope of application is more restricted.In addition, this grade beam structure is set, it need to tackle special engineering, the length of design basis beam does not possess the ability of batch production, the concrete of its use and reinforcing bar amount are also larger, are not very desirable on difficulty of construction, transportation and engineering time.And, front column and rear column are separately positioned on different grade beams, and its center of gravity lays respectively at the grade beam of top and the grade beam of below, and whole photovoltaic module support below does not have beam, in actual use, the photovoltaic bracket overturning moment that opposing wind load causes is more difficult
Utility model content
The purpose of this utility model is to overcome the deficiency of existing various bracket basis, and meets bracket basis safety, stable requirement.
For achieving the above object, the utility model adopts following technical scheme.
In a kind of photovoltaic plant, the simple and easy strip foundation of photovoltaic module support arranges structure, it comprises the grade beam that is arranged at ground, photovoltaic module support is arranged on this grade beam, this photovoltaic module support comprises front column and rear column, every group of front column of this photovoltaic module support is connected with single grade beam with rear column, and each grade beam is parallel being set up in parallel laterally.
This grade beam cross section is rectangular configuration.
Inside this grade beam, four jiaos are provided with vertical muscle, and vertical muscle outside is provided with some stirrups.
This grade beam cross section is inverted T shape structure, its T-shaped wider one setting that faces down.
Two jiaos of the T-shaped shorter one side of this basis Liangqi inner sides and lower position thereof are provided with vertical muscle, and vertical muscle outside is provided with some stirrups.
This grade beam top is provided with U-bolt or embedded iron parts, and this U-bolt or embedded iron parts are connected with photovoltaic module support.
This grade beam external surface is provided with anticorrosive coat.
Spacing between each grade beam is 2500-3000mm.
The beneficial effects of the utility model are as follows.
1, wider place applicability
Simple and easy strip foundation is by between column before and after the photovoltaic bracket, grade beam being set, thereby before and after basic center of gravity is moved between column, increased the basic overturning or slip resistance analysis arm of force, can only by basis, conduct oneself with dignity and be resisted the photovoltaic bracket overturning moment that wind load causes.
Simple and easy strip foundation and foundation soil contact area are larger, and this kind of base form can adopt in the situation that bearing capacity of foundation soil is lower, therefore adapt to the topsoil in various places.By add anti-corrosive rust inhibitor in concrete, the bituminous epoxy layer that the external surface on basis can brushing different-thickness is as anti-corrosion material, and place that can cannot be applicable at bolt piling bar is used.
2, quantity of material is saved more
The concrete in simple and easy strip foundation (square-section) and (inverted T shape) cross section and amount of reinforcement are much smaller than single footing and conventional strip basis, for conventional strip basis with the simple and easy strip foundation of this case in the situation that sectional area is identical, photovoltaic bracket for same form is arranged, the total length on conventional strip basis is 2 times of simple and easy strip foundation head factory substantially, and the length of concrete volume and reinforcing bar is also 2 times.
3, construction period is shorter
Spiral steel pile foundation needs special equipment to hole and drive piles in place.For fixing photovoltaic array, the quantity of front and back column is certain.Simple and easy strip foundation is that front and back upright post basic is constructed together, the spiral steel pile foundation of comparing, and the construction quantity on basis reduces half, and does not need special piling machinery.If simple and easy strip foundation is prefabricated, site operation speed can be faster so.
4, cost is lower
Obviously, the engineering quantity of simple and easy strip foundation is lower than single footing and conventional strip basis, so cost also can be lower than this type of basis.Compare with spiral piling bar, simple and easy strip foundation is used most basic constructional materials, does not need special factory's customization and produces, and according to Practical Project example experience, every cost per kw is 76% left and right of the every cost per kw of spiral piling bar.
5, site operation is less to environmental perturbation
Simple and easy strip foundation is directly placed on the topsoil in place, obtains the ability of enough anti-horizontal loadings by larger foundation ' s bottom area, does not therefore need larger buried depth, general buried depth 200mm～300mm, and whole place does not need large area boring and excavation.Vegetation deterioration area is few, and environmental perturbation is few.
