5 Claims, 10 Drawing Figures PATENTED FEB 8 1972 INVENTOR. NATALE J. TUM MA RELLO FIG 1 MEANS FOII ll/IGUNTING CONCIIETE STRUCTURAL MEMBERS This application is an improvement of my prior copending application, Ser. No. 23,302, filed Mar. 20, 1970 for MEANS FOR MOUNTING CONCRETE STRUCTURAL MEM- BERS, and my U.S. Pat. No. 3,507,315 granted Apr. 21, 1970.
This invention relates to means for mounting wall panels such as precast concrete slabs, prestressed concrete beams and girders, or for anchoring heavy machinery.
More particularly, the invention relates to mounting large heavy panels, for instance, synthetic stone panels or other heavy masonry pieces, or other heavy components such as large machines.
The invention is not limited to mounting wall panels, but may be used for mounting components in any plane, for instance, on walls, ceilings, floors, etc.
In my prior application and patent, the mounting nut is adjustable in one plane only. In the present application, the mounting nut is also adjustable in and out along its axis.
Many large office buildings are being built with their entire outer walls being faced with stone or synthetic stone panels instead of the conventional method of laying bricks. These panels are large and heavy and are generally prefabricated with mounting attachments incorporated or embedded in them so that the panels can be lifted up by a crane and bolted into place on the steel frame of the building.
The present invention provides fastening means which are adjustable laterally and along its axis to be aligned to receive a bolt which is mounted in a mounting hole of a structural member. The adjustment is provided by a pair of threaded members which are threadedly connected to a nut movable along coordinate axes so that the mounting hole can be lined up as required.
In modern building construction, heavy wall panels are bolted onto the frame of the building. These panels are hoisted in place by means of derricks. It is difficult or impossible to locate the panel mounting aperture in a precast concrete panel with sutficient accuracy. Therefore, adjustment means must be provided so that these panels can be secured to the building frame quickly under difficult conditions.
Accordingly, a principal object of the invention is to provide new and improved means for mounting precast concrete panels or members to a supporting structure.
Another object of the invention is to provide new and improved means for adjustably mounting precast panels or structural members to the frame of a building.
Another object of the invention is to provide new and im proved means for adjustably mounting precast concrete members comprising a nut member which is adjustable along three orthogonal axes.
Another object of the invention is to provide new and im proved means for fastening wall panels, structural concrete beams, girders, machinery and equivalent members to a supporting structure comprising a first internally threaded hollow member, said member being anchored to a member to be mounted on a supporting member with bolts, a second externally threaded member mounted in the threads of first member, said second member having a shaftway and a hollow interior space, a nut adapted to be mounted in said interior space, the outside dimension of said nut being greater than the diameter of said shaftway, and means to movably mount said nut in said interior space whereby said nut is adjustable in all directions in a plane perpendicular to its axis and along its axis to receive a mounted bolt.
These and other objects of the invention will be apparent from the following specification and drawings, of which:
FIG. I is a sectional view of an embodiment of the inventron.
FIG. 2 is a sectional view of the first internally threaded hollow member, reduced in size.
FIG. 3 is a top view of FIG. 2, reduced in size.
FIG. 4 is a sectional view of the second externally threaded member, reduced in size.
FIG. 5 is a top view of FIG. 4, reduced in size.
FIG. 6 is a sectional view of the locking nut, reduced in size.
FIG. 7 is a top view of FIG. 6, reduced in size.
FIG. 8 is a sectional view taken along the lines 8--8 of FIG. 2, reduced in size.
FIG. 9 is a sectional view of the nut, reduced in size.
FIG. I0 is a top view of the nut of FIG. 9, reduced in size.
Referring to the figures, the invention generally comprises a first internally threaded hollow member 1 which has an extending foot or anchor portion I. The anchor portion preferably has a T-shaped cross section, as shown in FIG. 8, and preferably has a pair of notches 3 and 4 for receiving anchor rods 3 and 4! for the purpose of securely anchoring the member I in the concrete wall panel 5, which is to be mounted on the structural supporting member 6 by means of the bolt 7. The structural supporting member 6 is mounted on a structural I-I-beam 8.
A second externally threaded member 10 is threadedly mounted in the member I. The member 10 has a hollow interior I I and a shaftway 12 to receive the bolt 7.
Mounted inside the hollow space 11 is a nut 13, the outside dimension of which is larger than the shaftway 12. The nut is fioatably mounted in the member 10 by means of a magnet 14 which is securely connected to the nut and which is magnetically connected to sheet metal 22 with ends bent to fit the interior lips 15, 15 of the member 10. The magnet 14 may be a plastic sheet impregnated with magnetic particles. Therefore, the nut can float inside hollow space 11, and self-centering bolt 7, which is inserted through the hole 7' in the structural member 6, can make thread contact with nut 13. Nut 13 is so shaped and sized that it will lock itself against the sides of hollow interior 11.
A locking nut cover 17 which is externally threaded to fit on member I and which has an extending lip I7 is adapted to engage the member 10 to lock it in place.
A plastic cylinder 20 and plastic cover 21 are mounted on the assembly so as to completely cover the assembly, and plastic insert 19 is set into bottom of member I. The purpose of the plastic cover and insert is to protect the assembly and keep liquid concrete out of the assembly while the panel is being poured. After the concrete is set, cover 21 is removed. In other words, the entire assembly is set in the concrete form and the panel 5 is poured in a form around the mounting assembly so that the mounting assembly is securely anchored in the cast panel by means of the foot portion 1 and preferably by reinforcing rods 3' and 4.
In operation, the panel 5 is mounted on a structural member 6 by first locating and aligning the panel as closely as possible with the hole 7. If there is any misalignment, the panel is moved out slightly from the structural member 6, and the assembly rotated by hand to line up the nut 13 with the hole 7. Preferably, the depth adjustment should be made first and then the locking cover 17 tightened up to lock the depth adjustment of the member 10. The nut 13 is still free to move in any direction or quadrant perpendicular to its axis by means of the magnetic holding member 14. Therefore, the self-centering bolt 7 may be inserted and the nut 13 will be moved by the tapering end of the bolt 7 so as to engage the threads of the nut 13. The depth adjustment is necessary if the building frame member 8 is warped, bent, out of plumb, or deformed in any way.
FIG. 2 is a detail sectional view of the member I and FIG. 3 is a top view of the member 1.
FIG. 4 is a sectional view of the member 10 showing the nut 13, and FIG. 5 is a top view of FIG. 4.
FIG. 6 is a sectional view of the locking nut cover 17 and FIG. 7 is a top view of FIG. 6.
FIG. 8 is a sectional view of the anchor member 1 taken along the lines 88 of FIG. 2.
FIG. 9 is a sectional view of the nut 13 and FIG. 10 is a top view of FIG. 9.
The mounting assembly may be mounted as deep as desired within the cast concrete member 5, depending on the thickness of the member 5. The only element that would need to be changed in size would be the plastic cover 20 and this cover could be color coded to indicate the proper depth of the mounting assembly within a particular panel. The length of the cover 20 automatically sets the depth.
The mounting assembly may be used for mounting heavy machinery, structural members and other heavy bodies.
