Abstract

A CMR (Cellular Mobile Radiotelephone) Cell Site includes a foundation for a CMR equipment edifice. The foundation, together with the edifice, rests on a leveled surface. An antenna tower is mounted on the roof of the edifice and is secured by an antenna mounting brace embedded in the roof of the edifice. The antenna is guyed at three elevations along the antenna's height to three points on the foundation. The edifice encloses a 10-inch-square, steel support column, positioned within the edifice directly beneath the antenna mounting brace, for supporting the antenna tower. Four-inch-thick slabs of concrete are inserted between the floor of the edifice and the support column and between the support column and the roof so as to isolate the interior of the building from electrical disturbances such as lightening.

Dependent claims

A CMR cell site comprising:

a foundation that includes:
(a) a rectangular center structure that includes a front section, a rear section, a left section, and a right section,
(b) a left leg section attached to the rear section and extending substantially cellinearly therewith,
(c) a right leg section attached to the rear section and extending substantially cellinearly therewith,
(d) a left exterior crossmember section attached to the left leg section and to the left section,
(e) a right exterior crossmember section attached to the right leg section and to the right section, and
(f) a nose structure attached to and extending from the front section, said CMR cell site further comprising:
an edifice having a roof and a floor, said roof residing above said floor, and said edifice resting on the foundation, the edifice for housing CMR equipment and ancillary equipment;
a tower brace supported by the roof;
an antenna tower mounted on and supported by the roof and secured by the tower brace;
a support column extending between the roof and the floor of the edifice for providing structural support for the tower;
and

and
(f) a plurality of guy wires attached between the antenna tower and the foundation for guying the antenna tower to the foundation.

15 more elements

A CMR cell site that is transportable to and rapidly deployed at a site location, the CMR cell site comprising:

an edifice having a roof and a floor, said roof residing above said floor, and the edifice for housing CMR equipment and ancillary equipment and for supporting an antenna tower that is erected at the site location;
a foundation that includes:
(a) a rectangular center structure that comprises a front section, a rear section, a left section, and a right section, wherein the left and the right sections each exhibit an oblique panel extending outwardly at a position along the length of the respective left and right section and wherein the rear section comprises a left bracket plate pair disposed at a left end of the rear section and a right bracket plate pair disposed at a right end of the rear section, each of the bracket plate pairs comprising a top bracket plate and a bottom bracket plate and each of the top bracket plates and the bottom bracket plates exhibiting a plurality of mounting holes;
(b) a left leg section having a top plate and a bottom plate and attached to the left bracket plate pair by virtue of mounting bolts inserted in the mounting holes of the left bracket plate pair and in mounting holes in the top and the bottom plates of the left leg section, said left leg section exhibiting an oblique panel extending outwardly at a position along the length of the left leg section;
(c) a right leg section having a top plate and a bottom plate and attached to the right bracket plate pair by virtue of mounting bolts inserted in the mounting holes of the right bracket plate pair and in mounting holes in the top and the bottom plates of the right leg section, said right leg section exhibiting an oblique panel extending outwardly at a position along the length of the right leg section;
(d) a left exterior crossmember section having first and second tongue portions extending at opposite ends of the left exterior crossmember section, said left crossmember first tongue portion removably attached to the oblique panel of the left section and said left crossmember second tongue portion removably attached to the oblique panel of the left leg section;
(e) a right exterior crossmember section having first and second tongue portions extending at opposite ends of the right exterior crossmember section, said right crossmember first tongue portion removably attached to the oblique panel of the right section and said right crossmember second tongue portion removably attached to the oblique panel of the right leg section;
and
(f) a nose structure attached to and extending from the front section;
SAID CMR CELL SITE FURTHER COMPRISING:
an antenna tower brace supported by the roof and having a base plate with at least three mounting bolts extending upwardly therefrom;
an antenna tower mounted on and supported by the roof and having a foundation plate with three apertures complementary to the three mounting bolts in the antenna tower brace base plate for securing the antenna tower;
a plurality of guy anchors, one each disposed at the nose structure, the left leg section, and the right leg section;
a plurality of guy wires attached between the antenna tower and the guy anchors for guying the tower to the foundation;
and
a support member interior to the edifice and extending between the roof and the floor of the edifice at a position beneath the antenna tower brace and the antenna tower for providing structural support for the tower and for providing isolation from electrical disturbances, the support member comprising (i) a column having a top and a bottom, (ii) a thickness of concrete between the bottom of the column and the floor, and (iii) a thickness of concrete between the top of the column and the roof.
