Description
Shear Resistant Building Panel Assembly Background of the Invention This invention relates to building constructions and, more particularly, to a form of construction with concrete panels supported by metal or wood studs or beams.
Many different types of cementitious building panels have been provided in the past to form walls, floors or roofs of building structures. Some of these panels have included insulation and others have included structures cast in the panels for attaching both interior and exterior finishing panels thereto.
Many examples of previously known cementitious wall panels are included in U.S. Patents 2,071,349; 2,270,672;
Many different types of cementitious building panels have been provided in the past to form walls, floors or roofs of building structures. Some of these panels have included insulation and others have included structures cast in the panels for attaching both interior and exterior finishing panels thereto.
Many examples of previously known cementitious wall panels are included in U.S. Patents 2,071,349; 2,270,672;
2,704,935; 3,442,056; 3,956,864; 4,112,646; 4,185,437 and 4,602,467. Many of these include various projections for providing a bond between the metal studs or beams and formed concrete panels. These include projecting lugs of various designs, etc.
It is the object of the present invention to provide a support system for pouring a concrete panel in which the connectors between the panels, metal or wood studs or beams and concrete panel have high shear resistance.
Summary of the Invention The present invention in its broadest aspect relates to a novel connector for joining formwork panels to supporting studs or beams such that high shear resistance is provided in a concrete panel formed on the formwork panels. This connector is a dished shear connector having a flat base and upturned skirt portion formed from heavy gauge sheet steel. A
plurality of these shear connectors are positioned on the formwork panels in alignment with the studs or beams, and with the skirt portion extending outwardly away from the formwork panels. In this position the shear connectors, formwork panels and studs or beams are securely fastened together and a concrete panel is poured on the formwork. The concrete surrounds the upturned skirt portions resulting in an extremely strong structure have, in particular, high shear resistance, i.e. it resists sliding or lateral movement between the components of the floor structure when subjected to shear forces.
One preferred embodiment of the present invention comprises a formwork assembly including a plurality of C-shaped sheet steel channel beams, each having a central web and inner and outer flanges, these beams being laterally spaced from each other. Sheet steel formwork panels are placed in contact with the outer faces of the inner flanges and extend across between the channel beams.
A plurality of said dished shear connectors are placed at spaced locations on the formwork panels and in alignment with the beam inner flanges. Then the dished connectors, formwork panels and studs or beams are connected together by means of screws or welds. With the formwork assembled in this manner, a concrete panel is formed on the formwork panels with the shear washers embedded therein.
When connector screws are used, they may be tightened to a position in which they draw the metal surrounding the screw consisting of the flange, formwork and shear connector into a coextensive generally conical configuration. This provides exceptionally high shear resistance between the concrete slab, the formwork and the stud or beam.
The dished shear connector is typically a washer made from 12 to 16 gauge sheet steel and is preferably circular with a diameter of about 2 to 3 inches and a skirt 2a height of about 0.5 to 1 inch. The free edge of the side wall is preferably fluted. It is also advantageous to use at least two screws to hold the shear washer securely to the beam.
According to an alternative embodiment of the invention, the screws for holding the dished shear washer may be replaced by a welded connection, such as a spot weld or a plug weld.
Such welds are easily carried out and are also highly effective in terms of shear resistance.
According to a still further embodiment of the invention, it is possible to substitute the C-shaped steel channel beams with wooden beams. These are used together with the screws and dished washers to provide a very inexpensive structure having high shear resistance.

mesh 18 is positioned above the dished washers 15 and a concrete panel 25 is poured on top of formwork panel 14. The coextensive conical areas surrounding the screw provide very high shear resistance between the formwork panel 14 and flange 12, as well as against the concrete 25.
The dished shear washer 15 has a substantially flat bottom face with an upturned skirt portion and an axial hole.
According to an alternative embodiment as shown in Figures 3 and 4, the dished shear washer 20 has a flat bottom wall 21 with holes 22 and a skirt portion 23 with flutes 24. This fluted design gives greater strength and greater shear resistance between the dished shear washer and concrete.
Figure 2 shows an embodiment in which the steel channel member is replaced by a wooden beam 39. This is particularly useful in wooden frame construction where the wooden beams form part of the final structure. As with the steel channel, the screw 16 forms a very strong connection to the wood and firmly holds the dished washer with excellent shear resistance.
Details of how the dished shear washers function can be seen in Figures 5 and 6. Channel members 70 are used having a web portion 71, a short top flange 72 and a large bottom flange 73. Formwork panels 14 with service channels 26 are laid on top of flange 72 and these are then joined by the dished shear washer 20 and.screws 16. Reinforcing mesh 18 is placed above the shear washers and a concrete panel 25 is poured. Hat channels 74 are connected to the bottom flanges 73 and these support ceiling panels 75.
A typical full assembly of a deck including a series of studs or beams 10, formwork panels 14 and dished shear washers 15 is shown in Figure 8. From Figures 7 and 8, it will be seen that the formwork panels can take various forms and in Figure 7, it includes a flat panel 27 and recessed sectians 26 which provide runways for electrical and mechanical services.

10 Particular designs for special construction situations are shown in Figures 15, 16 and 17. In Figure 14, a pair of channel members 40 are positioned back-to-back and they serve to outline a large beam. Additional metal panels 41 and 42 are placed laterally from the back-to-back channels 4o to create a formwork which is filled with concrete 46.

C-shaped members are typically made from 16 to 11 gauge pickled and oiled or galvanized steel with web heights ranging from 6 to 18 inches. The formwork panels are typically made from about 28 gauge steel with a concrete panel having a thickness of about 2 to 2.5 inches formed thereon.
The desired shear resistance is at its maximum against the concrete when the capacity of the screw in shear is matched with the metal of the beam and that of the dished washer. For instance, a dished washer made of 14 gauge steel having an area of 1.75 in2 against concrete capacity of 2500 psi offers 4375 psi resistance at the concrete after 28 days and a resistance of 2187 psi after 24 hours. This resistance of 2187 psi is sufficient to allow early removal of temporary shoring. If a screw is used having allowable capacity of 2000 psi in shear, then all components are closely matched fox maximum shear resistance.
A particularly preferred embodiment of this invention is the one shown in Figures 3-6, using a 28 gauge steel deck connected to 16 gauge steel C-channels by means of shear washers having a diameter of about 2.5 inches and a height of 0.75 inch made from 14 gauge steel and each held by two #14 screws. When a concrete panel 2 to 2.5 inches thick is poured on this formwork, the shear washer provides 5000 psi maximum shear resistance when connected to a concrete slab having a strength of 3500 psi. The shear resistance in the C-channel is 6,000 psi and the two screws provide a minimum shear resistance of 5,200 psi.
