专利汇可以提供Modular utility vault专利检索，专利查询，专利分析的服务。并且A modular construction for underground utility vault. Semicylindrical end sections are molded in the form of a relatively thin shell from fiberglass or other moldable material of similar physical characteristics. The shells are formed with a series of radially offset circumferentially extending ribs which provide increased rigidity to the shell and also form shelves for supporting elements such as transformers, connection points, etc. within the vault. The end section is one form of structural module which may, in some installations, be combined with a second modular element in the form of a flat side panel having a cross-sectional configuration matching that of the end section. Two end sections may be secured to each other to form a cylindrical vault or, alternatively, two end sections may be assembled with one or more pairs of side panels attached to and mounted between the opposed end sections. A cover element of laminated molded sheet material closes the opening at the upper end of the completed vault and is provided with internal stiffening ribs. A lock and retainer-hinge assembly is employed to releasably lock the cover in position and enables the cover, when unlocked, to either be swung upwardly as on a hinged mounting or removed entirely.，下面是Modular utility vault专利的具体信息内容。

权利要求

1. A utility vault comprising a pair of like semicircular sections of a molded plastic material having a high strength-toweight ratio, such as fiberglass, each of said sections comprising an axially elongate generally semicylindrical shell of relatively thin uniform wall thickness, a plurality of radially offset circumferentially inwardly extending ribs integrally formed in each of said shells, the ribs on the respective shells being axially aligned with each other to extend continuously around the periphery of the tubular vault, each rib having a flat substantially horizontal first wall extending radially inwardly from the semicylindrical shell wall and a frusto-conical second wall integral with and inclined outwardly from the radially inner edge of said first wall to the semi-cylindrical shell wall, the first walls of said ribs being disposed on the upper side of said ribs when said tubular vault is in an upright position, to define a plurality of peripherally extending shelves in the interior of the vault, the uppermost one of said shelves being located in adjacent spaced relationship to the upper end of the vault to constitute a closure seat, said ribs further defining frustoconical channels in the exterior walls of said shell with the upper wall of said channels being substantially horizontal, means on the vertical edges of each of said sections for securing said sections together to form a tubular vault, and a cover closure comprising an upper and a lower member of sheet plastic material having a high strength-to-weight ratio, such as fiberglass, said lower layer being interconnected to said upper layer and having vertically extending rib sections having a depth substantially equal to the vertical spacing between said upper end of said vault and said uppermost one of said shelves.

2. A vault as defined in claim 1 wherein said securing means includes a pair of like side panels secured to and extending between said semi-circular sections, each of said side panels having a generally flat configuration and having a plurality of offset ribs thereon identically matching the interior and exterior configuration of said ribs on said semi-circular sections and defining a continuation of said interior shelves and said exterior channels.

3. A vault as defined in claim 1 wherein said ribs define at least two shelves in addition to said uppermost one of said shelves, one of said two shelves being located adjacent said uppermost one of said shelves and the other of said two shelves being located adjacent the lower end of said shell.

4. A utility vault as defined in claim 1, wherein said closure cover comprises a generally flat upper lid member, shaped to overlie and project outwardly beyond the upper rim of said tubular vault and said lower lid member is integrally bonded to the lower side of said upper lid member and said rib sections comprise uniformly spaced vertical inner and outer ribs extending substantially around the peripheral area of said lower lid member, with uniformly spaced vertical ribs extending transversely of said lower member between opposite locations on said inner rib.

5. A utility vault as defined in claim 1 including means for locking said cover closure in place to enclose the upper end of the vault, means defining a lock receiving recess in said cover closure having a hasp receiving opening therein, said means for locking including a hasp fixedly secured to said uppermost one of said shelves and projecting upwardly therefrom through said opening, and detachable hinge means on the side of said vault opposite said locking means comprising pin means fixedly secured to at least one of said shells above said uppermost shelf and projecting radially inwardly, and opening means defined in said vertically extending rib section of said cover closure for receiving said pin means to detachably and hingeably couple said cover closure to said shells.

6. In a utility vault designed to be buried in tHe ground with its uppermost part substantially flush with the ground surface, means on the uppermost part of said vault defining an upward-facing closure seat, a cover for said vault comprising: a generally flat horizontal lid member shaped in conformity with said uppermost part of said vault, a generally flat lower horizontal member spaced below said lid member, each of said members being of fiberglass or the like, a peripheral flange and a plurality of vertical ribs integrally bonding said members to each other, means defining a releasable lock between said walls and said cover, a pin projecting horizontally inwardly of said vault above said seat, and means for defining an opening in said peripheral flange loosely receiving said pin to positively retain said cover on said seat in cooperation with said lock and to accommodate hinging and removal of said cover when said lock is released.
