Demountable multiple level building structures
| Details |
Inventors: Rice, Edward K.;
Assignee: Unicon Parking Structures, Inc. (Van Nuys, CA)
Primary Examiner: Faw, Jr.; Price C.
Assistant Examiner: Raduazo; Henry
Attorney, Agent or Firm: Lyon & Lyon
A multiple level building structure utilizing a first set of precast reinforced concrete modules having integral supporting legs separated by a second set of precast or in situ cast reinforced concrete modules, each of the second set of modules being supported along opposite side margins by members of the first set of modules; the structure also including, if desired, a third set of modules of greater width than the first or second set of modules, the modules having tendon guideways therein and being secured together by removable post tensioning tendons strung through the guideways. |
|
DETAILED DESCRIPTION I claim: 1.
A method of constructing a building structure, characterized by: a.
precasting supporting modules, each having transverse guideways; b.
positioning the supporting modules in predetermined spaced and coplanar relation; c.
stacking similarly positioned supporting modules thereon to form a multiple level structure; d.
extending tendons through the guideways and between the supporting modules of an upper level; e.
placing a casting form to extend between spaced supporting modules at said upper level; f.
casting a supported slab in the form and around the portions of tendons extending between the supporting modules; g.
lowering the casting form to a lower position at the level of a lower pair of spaced supporting modules while having said cast slab supported at said upper level; h.
extending tendons through the guideways and between the supporting modules at the lower level; i.
casting a further supported slab, in said casting form and repeating said step of lowering said casting form and repeating said step of lowering said casting form; j.
and after completion of each level tensioning, the tendons exert transverse compression loads in the supporting and supported modules.
2.
A method as defined in claim 1, wherein said casting form is suspended by cables and the supported slabs are cast about the cables, characterized by: a.
sliding the cables through any previously cast supported slab as the form is lowered to a lower casting position.
Description:
BACKGROUND AND SUMMARY OF THE INVENTION Reference is made to my previous application for a Precast Concrete Building Construction, filed June 2, 1969, Ser.
No.
837,986.
Disclosed in the previous application is a multiple story structure primarily adapted, but not limited, for use as a parking garage, the structure utilizing a set of precast reinforced concrete units or modules, each comprising a slab and four supporting legs.
These are set side-by-side and end-to-end, as well as stacked vertically to form a multistory structure
