Abstract
The present invention relates to a roof adapted to cover a manure storage tank. The roof comprises a plurality of trusses and sheeting members. The roof is constructed so as to minimize the lateral forces on the manure storage tank and to eliminate vertical forces on the centre point of the floor of the storage tank.
Description

S
A number of covers for manure storage tanks are known in the art. A number of these are inflatable covers which do not provide for ventilation of thf; storage tank.
Access to the manure storage tank for emptying of the storage; tank, for example, is difficult. Furthermore, the life span of inflatable cover members is limited. Such covers also need to be secured to the storage tank. These are often secured to the tank in such a fashion that forces oru the cover are transmitted laterally to the tank which could lead to cranking of the said tank.
Other non-inflatable domes have a very complex structure. ~y way of example, Canadian patent application 2,220,382 provides a ventilated flexible dome. The dome includes a circular base, a rigid ridge pole, support cables connecting the base to the ridge pole:, a cover and a flexible membrane arranged on the support cables, a ventilation cone with a r~_gid ridge pole. The construction of such a dome cover is complex and a cable arrangement i~; necessary to support the structure. Furthermore, the cover attaches tc> the outside of the storage tank and, as such, any pressure applied to the cover would create lateral forces on the storage tank which increases the risk of cracking of fhe storage tank.
The roof of the present invention has a structure which affords it flexibility to withstand the forces applied thereon. Furthermore, the structure of the roof is such as to minimize lateral forces applied to the storage tank thus minimizing the risk of cracking thereof It is important to minimize the risk of cracking of the manure storage tank which could result environmental damage and in costly clean-up operations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The roof 10 is adapted to cover manure storage tank I2 having a generally cylindrical wall structure. The roof 10 has a frusto-conical configuration. As illustrated in Figure 2, it comprises a central, tubular hub 14. The hub 14 comprises an upper ring 1b and a lower ring 18 spaced from one another by members 20 which are disposed perpendicularly to the rings 16 and I8. The hub I4 can be made of steel.
As seen in Figures 2 to 4, the roof 10 also comprises a plurality of trusses 22 which ~°xtend ~-adially outwardly therefrcnn. ~t'11e trusses 22 are made of steel or of other suitable material having comparable strength characteristics. Each truss 22 has a proximal end 24 and a distal end 26. The proximal end 24 of each truss 22 is connected 'to the hub I4. The hub 14 serves to anchor alI of the trusses 22 and allo~,vs for the roof to be constructed without a central support post. This avoids the disadvantages associated with. a cent~~al support post, namely the transmission of vertical forces to the floor of the tank 12 and the associated risks of cracking of the tank I2 which could result therefrom. The hub 14 also allows for ventilation of the gases emanating from the storage tank I2.
Each truss 22 comprises parallel upper beams 28 and lower 'beams 30 spaced apart and secured together by V-shaped chord members 32 and intermittent vertical cormecting members 34 which extend perpendicularly to the upper 28 and lower 30 beams.
Support beams 36 interconnect the upper beams 28 of the adjacent trusses 22. The support beams 36 can be secured to the upper beams 28 of the trusses 22 by means of screws. The upper beams 28 of the trusses 22 and the support beams 36 form the upper surface 38 of the roof 10.
1 S A post member 40 extends perpendicularly to the distal end 26 of each parallel upper beam 28 and lower beam 30. W a preferred embodiment as illustrated, the post member 40 is an I-shaped beam. The post member 40 has an upper end 42 and a lower end 44. The lower ends 44 of the post members 40 form the periphery 46 of the roof 10.
Sheeting panels 48 serve as a covering for the roof 10. The sheeting panels 48 are preferably made of steel. They can also be made of any other suitable material such that the panels have suffrcient strength and are impermeable, such. as corrugated tar paper panels and the Like. The sheeting panels 48 are secured to the upper surface 38 of the roof I O. In a prefez~ed embodiment, the sheeting panels 48 are secured by means of screws to the support beams 36.
Plate members 50 having low frictional surfaces are secured to the lower end 44 of the post members 40. In a.preferred embodiment, the plate member 50 is made of polyethylene such as UHMW polyethylene. The plate members SO minimize the lateral forces which will be transmitted from the roof 10 to the manure storage tank I2.
As seen in pigure 5, the lower ends 44 of the post members 40 are secured to the storage tank 12 by means of brackets 52 which will prevent the roof 10 from lifting off the storage tank 12. The brackets 52 do not prevent the movement back an<l forth of the post membE;rs 40.
As seen in Figure 6, a reinforcement belt 54 comprising a plurality of interconnectef. units 56 is secured about the outer surface of the post members 40. The reinforcement belt <~4 will prevent the post members 40 from being displaced off the surface of the storage tank: 12 by the forces being exerted on the roof I0, such as the weight of snow during the winter, which could result in the collapse ofthe roof 10.
In a preferred embodiment: which is not illustrated, an access door can be constructed! in the roof 10 by making an opening between two adjacent trusses 22 in one of said sheeting panel 48 and through the support beams 36 and securing a door in said opening. The door can be used to gain access to the storage; tank 12 without having to remove the roof I O from the tank IS i2.
In use, the roof 10 is placed on the manure storage tank 12. It is secured to the storage tank 12 by means of the brackets 52. The construction of the roof 10 is such that it can withstand forces applied thereon, such as the weight of snow during the winter time. The plate members 50 minimize the transmission c~f lateral forces from the roof 10 to the storage tank 12 which could possibly lead to the cracking of the tank 12. 'The reinforcement belt 5~4 is secured about the outer surface o1"the post members 40 to prevent their displacement off the surface of the storage tank and the resulting collapse of the roof I0.
In the drawings and specification ., there have been disclosed typical Preferred embodiments of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and riot for purposes of limitation, the scope of the invention being set forth in the following claims.
