Definitions

  • laminas of insulation have been inserted between an inner structural concrete wall panel and an outer decorative concrete face panel or shell.
  • the assembly be tied together to provide no significant movement of the various lamina relative to each other.
  • the face panel be sufficiently integrated with the structural panel to prevent inadvertant loss thereof such as sliding off of the face shell during shipment or erection or pulling off due to wind suction.
  • differential temperature effects could cause thermal cracking of either the structural or face panel if there is no flexibility or capability of yielding in the connection between the panels.
  • the present invention provides a tie system to integrate the face panel, insulation panel and structural panel to provide good performance and minimize thermal cracking and also provide sufficient integrity to maintain a tight interface between the insulation and structural panel and prevent the entry of water therebetween.
  • a precast insulative concrete panel construction comprising a first concrete panel section having longitudinally extending reinforcing rods, insulative panel sections super-imposed on said first panel section and having gaps between said sections, a second concrete panel section having corresponding longitudinally extending reinforcing rods and tie means to connect said reinforcing rods of said first and second panels, to maintain said panels in unitary assembly and to allow for non-composite expansion and contraction of said panels due.to temperature differentials so that cracking of said panels due to temperature changes is minimized.
  • the tie means comprises C-shaped ties having allochiral hook end portions with said end portions engaged with said reinforcing rods and said ties having a thickness greater than 3.76 mm (.148 inches) and less than 12.7 mm (.5 inches).
  • the invention further provides a method of making a composite concrete insulative panel comprising the steps of:
  • the invention provides a sandwich wall panel and method of making the same which includes an insulative lamina sandwiched between a structural concrete panel and a concrete face panel.
  • a system of integrating the panel sections and insulative lamina is provided which minimizes composite action of the panel under stress which could lead to thermal cracking due to differential temperature effects.
  • the structure which integrates the three lamina maintains a tight interface between the insulation and the structural panel.
  • C-shaped ties connecting longitudinally extending reinforcing rods in both concrete panels and having a diameter of 6.35 to 4.76 mm (of 1/4 to 3/16 inch) were found to provide the desired balance between rigidity and non-composite action.
  • the method of the invention relates to the assembly of the panels wherein the C-ties are held in place, while the cast structural panel is wet, by the abutting ends of the overlying blocks of insulation.
  • the abutting ends are pressed against the C-ties with the lower hook of the C-ties engaged with the reinforcing rods in the lower panel.
  • the reinforcing rods for the face panel are pressed into the upper curves of the C-ties by blocks of wood supported on the insulation to properly orient and position the reinforcing rods in the upper hook portions and support the reinforcing rods until the face panel has cured.
  • Fig. 1 shows a sandwich panel 8 which includes a pre-stressed concrete structural panel section 10 which can be formed by an apparatus such as that shown in U.S.-A-3,382,304 or U.S.-A-3,979,171.
  • the panels can be 10.16 cm., 15.24 cm., 20.32 cm., 25.4 cm., 30.48 cm., (four inches, six inches, eight, ten or twelve inches) thick.
  • wall panels are 15.24 cm or 20.32 cm (six or eight inches) thick.
  • C-shaped ties 16 preferably formed from stainless steel are embedded in the panel and, as illustrated in Fig. 2, hooked around the strands 14.
  • the connector ties 16 have hook shaped ends in allochiral relation.
  • the C-ties 16 are positioned between the abutting ends 21 between adjacent insulative panels 20, as illustrated in Fig. 1 and 3.
  • the insulative panels 20 are pressed together as the C-ties are inserted to support them in wet concrete.
  • the C-ties 16 can be arranged in a pattern as illustrated in Fig. 3, with four C-ties adjacent the ends of the panel, with two C-ties staggered at spaced intervals along the length of the panel. With the use of 121.92 cm (4 foot) insulation panels the C-ties 16 are spaced at 121.92 cm (4 foot) intervals.
  • Tests were conducted to compare the measured deflection of the face panel with the theoretical composite deflection and the theoretical non-composite deflection when a load was applied to the structural panel. Bars measuring 3.175 mm by 25.4 mm (1/8 inch by 1 inch) were tested as ties between the panels and were found to provide too much composite action which could lead to panel cracking due to differential temperature effects.
  • Figures 5, 6, 7, and 8 illustrate comparison of test results with theoretical calculated composite and non-composite deflections.
  • a face tie arrangement such as that shown in Fig. 1 was employed with the ties at a 121.92 cm (4 foot) spacing.
  • the structural panel cross-section was 15.24 cm (6 inch) pre-stressed with 5.08 cm (2 inches) of urethane insulation plus a 5.08 cm (2 inch) thick facing panel.
  • the tests involved a panel 8.38 m (27 feet 6 inches) in length.
  • the panels were supported at two points 160 cm (5 feet 3 inches) from the ends.
  • the panels were loaded up by piercing the face panel and insulation and applying the load directly on the panel 10 and deflections were measured. Both cantilever and main span tests were performed.
