supporting the glass bodies 2 are formed square and are provided at all four corners with extensions 3 in the form of laterally projecting abutments, and the width of the spaces 4 and 5 is determined by the dimensions of the adjoining abutments 3. The edges 7 of the glass panels 2 which are undercut as at 8 are so inserted in the frames 1 that the inner surfaces 9 of the abutments 3 are opposite to the undercut edges 8. The iron rods 6a are of rectangular cross-section and are embedded in the cement which fills the longitudinal spaces 4, the the iron rods 6b which are of circular cross-section lie similarly in the transverse spaces 5. The iron rods 6a, 6b are not connected in any particular way to the abutments 3 of the frames 1, but are secured in their position by the binding material which fills the intermediate spaces. The sides 7 of the glass panels 2 are undercut or tapered from the upper to the lower side in order to obtain a maximum area for the passage of light. Figure 4 shows a modified form of the metal frame for use in concrete structures as above described, the corners 1a of these frames being of special construction. In the arrangement shown each corner is provided with angular abutments 10 having an exterior recess 11. The four adjoining corners 1a of the frames, each having an exterior recess 11, form an opening of suitable shape, which facilitates the insertion of the binding material at the junction of the frames and at the crossing of the iron rods 12 lying thereunder. By this means an otherwise weak point of the structure is efficiently avoided. Having now particular described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:— 1. A building element for use as part of a glazed reinforced concrete structure consisting of a metal frame adapted to support a transparent panel and having lateral projections serving as distance pieces for the adjacent elements.2. A glazed reinforced concrete structure comprising a series of metal frames each adapted to support transparent panels and having lateral projection so relatively arranged that spaces are left between the edges of each adjacent frame, these spaces being filled with cement or other binding material and containing reinforcing metal rods as set forth. 3. A building element of the kind set forth in Claim 1 comprising a frame having a rim for supporting the transparent panel, this rim being provided with extensions forming lateral abutments for the adjacent edges of the transparent panel the edges of which are preferably undercut and tapered as and for the purpose set forth. 4. A building element of the kind set forth in Claim 1 herein the adjoining corners of the lateral flanges form an opening as and for the purpose set forth. 5. The building element for use as part of a glazed reinforced concrete structure as described and illustrated in Figures 1 to 3 or in Figure 4 of the accompanying drawings. Dated this 25th day of October, 1909.
