Abstract
A concrete pouring form for use in permanently joining at the job site precast reinforced or prestressed posts and beams. The posts and beams are precast and will be used in the erection of the building when they have reached their maximum strength. Only sufficient concrete will be poured at the job site, as needed, to interconnect the posts and beams and perhaps the floors. Forms are used for joining together the adjacent ends of the posts and beams and providing therebetween a cavity into which concrete can be poured. The forms are preferably sectional so as to be separated and removed after the amount of concrete poured at the jobsite has set fully. These forms have clips thereon which can be connected with suitable guy supports for stabilizing the joint during the setting of the poured concrete therein.
