illllullllln ITTORNEV CONCRETE INSERT APPARATUS This invention relates to concrete insert apparatus, in general, and more particularly to such devices possessing full adjustability and therefore the capability of assuring registration with an object to be fixedly mounted on a concrete floor.
The prior art discloses a multiplicity of insert or anchoring devices for concrete. Certain early devices utilized, possessed disadvantages, as once embedded in the concrete they were not capable of being easily adjusted thereby consuming valuable time and therefore, if care and precision were not taken in so embedding these devices, they would not register with the holes of the object to be secured to the concrete floor or wall; and to achieve registration often became a costly task,.
Cognizant of this problem, other insert devices permitted adjustability over limited regions. Such devices suffered in that their adjustment factors were relatively small and hence time-consuming care again had to be exercised in embedding such devices. Certain of these devices employed capative nuts with complicated restraining members, difficult and costly to fabricate. Another disadvantage of such devices was the susceptibility of jamming the device if concrete were accidentally poured within the inserts cavity during the embedding process.
Certain other adjustable devices maintained or permitted the securing means enclosed within the inset to be finally positioned at some angle with respect to the concrete floor or surface, making it difficult to attach the machine or other device thereto.
Still certain other prior art devices as inserted in the concrete protmded from the floor surface and hence if heavy machinery were moved or pushed along the floor, such devices would naturally interfere with the consequent motion.
it is therefore an object of the present invention to provide improved concrete insert apparatus capable of being easily adjusted, offering no major obstacles protruding from the concrete floor, made in simple and economical configurations.
These and other objects of the present invention employ a longitudinally tubular member disposed about a given axis and having an open faced end; a bolt member ofa length less then the length of the longitudinal member has a threaded end and a head end portion, and is coupled within the tubular member to permit positioning of the bolt along any one ofa plurality of axes parallel to the given axis and intersecting the area bounded by the open faced end of the tubular member; while further permitting the threaded end of the bolt member to extend beyond the surface of the concrete after initial adjustment of the bolt has been made corresponding to any desired position, while finally maintaining the bolt completely below the concrete floor.
Other objects and advantages will become apparent in the ensuing specification and appended drawings, in which:
FIG. I is a vertical sectional view of a concrete insert according to this invention.
FIG. 2 is a vertical sectional view of an alternate embodiment.
FIG. 3 is a vertical sectional view ofa further embodiment.
FIG. 4 is a vertical sectional view of another embodiment further showing a machine device secured to a concrete floor utilizing the embodiment.
FIG. Sis a sectional view ofa further embodiment.
FIG. 6 is a sectional view of still a further embodiment. Referring to FIG. I a longitudinal tubular member 10 is disposed about a given axis I1 and is shown embedded in a concrete slab [2. Member I is shown as having a frustoconical cross section, but other configurations as rectangular, cylindrical and so on, would suffice. The frustoconical section has advantages in that it offers resistance to forces directed upwards and along axis II from pulling the insert out of the concrete slab 12.
The bottom face 14 is closed while a front face I is opened. The bottom face 14 has a hole or aperture l6 therein,
oriented about axis 11. An eyebolt 18, or other suitable fastening device is inserted through the hole in the face 15 and secured to the tubular member by means of a nut [7 or other locking device. The eye end of the bolt I8 is coupled to a chain member 19, having first and last links. The chain I) may be fabricated from a strong constructrial material as steel, iron, etc., as is the eyebolt l6.
A bolt member 20 ofa length less than the length of the tubular member 10 is positioned within the hollow of member 10, and has a threaded end and a head end, which has an eye configuration. The last link of the chain 19 encircles, and therefore couples the eye of the bolt or the head end, to the tubular member 10 via the chain l9.
FIG. I shows a grouting 21 oriented within the hollow cnclosed by the tubular member 10 and serves to maintain any desired position of the bolt 20 within the member l0.
Before the insertion of the grout material 21, the bolt 20, is loosely positioned as indicated above The length ofthe chain [9 plus the length of the bolt 20, enable the threaded end of the bolt to move in a vertical direction along axis ll, to permit the threaded end of the bolt 20 to be positioned above the concrete floor 22. The length of the chain 19 also permits positional variation of the bolt 20 along all axes parallel to axis ll, for example as axis to. Such axes include all axes which are parallel to axis ll and intersect the area hounded by the open face IS.
The assembly comprising elements l0, 16, 20 is first embedded in the concrete slab [2 in accordance with predetcrmined dimensions of a machine member to be secured to the concrete floor. The assembly may be capped during this process to avoid cement or concrete from entering the cavity of tubular member I0. Any cap is convenient as the bolt 20 is within the hollow confines of member 10 and does not protrude therefrom.
The machine, to be secured, may have two or more bolt-accomodating holes located at different points on the periphery of its base, each of which is to be associated with an insert device, as shown in FIG. I, and located at an approximate position of the floor. The machine is then pushed or slid into place, conveniently, as the insert devices offer no protrusions above the floor and hence do not offer obstacles. When the machine is so positioned, the workman reaches into the hollow of tubular member It] with a long-nosed plier on other suitable device and captures the loosely positioned bolt 20. He then inserts the bolt through the corresponding accommodating hole in the base assembly of the machine and fastens a nut 23 thereto. After all bolts, as 20, of the devices are thusly secured to the machine base, he fills the hollow recesses with a suitable grout or epoxy material 2] by means of any exposed area of the open face 15, not overlapped by the machine leg. After the grout material hardens it fixedly couples the chain 19, the bolt within 6 and to the tubular member lit. The frustoconical shape shown serves to further lock the grout material and therefore the member It) to the concrete when a force is applied upwards along axis ll.
FIG. 2 shows a sectional view of an alternate embodiment. A longitudinal tubular member 30 is disposed about an axis 3]. The member 30 is of a frustoconical configuration and may be fabricated from steel or some other suitable constructrial material. A bolt member 32 has a threaded end and a head end. The head end of the bolt 32 is of a relatively larger dimension when compared to the dimensions of the shaft of the threaded portion of bolt 32. The bolt 32, as shown, before insertion of the grout 34, is simple placed within the hollow confines of the tubular member 30. and does not protrude therefrom, as the length of bolt 32 is less than the height of the tubular member 30. After the member 30 is embedded in a concrete slab 38, and the machine to be secured, with its accommodating hole, is positioned; the workman captures the bolt and raises the bolt so that the threaded portion protrudes through the top opening face 34 and through the accommodating hole in the machine. The nut 33 is then coupled to the threaded end of the bolt 32, which is restrained from turn ing by the workman. The bolt 32, as positioned is therefore on an axis parallel to axis H and substantially perpendicular to the plane containing the concrete floor 39. The grout is then poured into the hollow of member [0, through the open faced end 35 and allowed to harden, thus fixing the bolt 32 in the operational position.
The bolt 32, as can be seen, can be positioned before the in sertion of the grout along any axis parallel to the axis I I, while permitting the threaded end to protrude above the open face 35 or above the concrete floor 39. The head ofthe bolt 30 is dimensioned so that the distance 37 from the center or axis of the threaded shaft to the end of the side of the bolt head is approximately equal to that distance 40, between a line 4| drawn parallel to axis II from the inside surface of the tubular member before the frustoconical section, to the sloping wall of the frustoconical section at a distance 43 above the base 36.
FIG. 3 shows a longitudinal tubular member 50, which may be of a cylindrical or rectangular configuration having a base 5| with a surrounding flange 52. A hole 54 in the approximate geometrical center of the base 5|, accommodates a screw or bolt member 55 which has one end coupled to a expandable or flexible steel cable 56. The other end of cable 56 is fixedly coupled to the head end ofa bolt 57 having a threaded portion at the other end thereof.
lt can be seen from the figure that positional variation is the same as that shown above, with the cable SI for example, replacing the chain member 19 of FIG. 1. The grouting 56 serves to maintain and couple the bolt 57, the cable 56 to the member 50 in the desired position parallel to the axis 59.
FIG. 4 shows a sectional view of an anchoring device having a grout accommodating passageway 60 contiguous with the hollow enclosed by a longitudinal tubular member 6|.
Briefly, longitudinal member 61 has a base 63, an eye bolt 64 through a hole in the base and secured to the base by means of a nut 65.
A chain 66 is coupled between the eye aperture of bolt 64 and the eye of the anchoring bolt 67. As such the elements shown are similar to those shown in FIG. I and are capable of all the easy positional and adjustability aspects of the device described in conjunction therewith.
The difference being the passageway, 60, which communicates with the hollow enclosed by tubular member 6 I.
in certain applications the machine leg 69 may be of such large dimensions as to cover the open face of the tubular member, This presents no problem in securing the bolt 67 thereto, as the machine 7| may be lifted slightly above the insert and the bolts thus inserted and secured with an ap propriate nut as 70. The machine 71 is thusly located, but not yet rigidly fixed to the concrete floor. However, the machine when lowered to the concrete floor 73, has the legs 69, thereof, covering the open face area and hence one cannot insert the grout.
For such latter applications a tubular member 62 has a passageway 60 therein communicating at one end with the hollow of the tubular member 6l via a hole 64 drilled in the side of the member 6], and terminating at the other end at an open face lying in the same plane as the open face of tubular member 6|. The member 62 may be so secured by any suitable means such as threading, force fit and so, with the hole 64 in member 6].
The entire assembly as shown is embedded in the concrete slab 73. After securing the machine 71 grout is poured into the top open face of member 62 and enters the hollow cavity as shown. The location of the hole 61 is such as to ensure that the grout as poured will fixedly couple the chain 66 and the bolt 67 to the tubular member 6]. The member 62 as embedded in the concrete offers further resistance to a force in a direction tending to pull the entire assembly from the concrete slab 73.
FIG. 5 and FIG. 6 show sectional vertical views of alternate embodiments of concrete inserts according to this invention, having grout accommodating members 85 and 86 with passageways and 8| respectively, further showing cap covers 82 and 83 for the respective open face ends of longitudinai tubular members 85 and 86, and cap covers 87 and 88 for the open face ends of the grout passageway members 89 and 90. Such units as shown in FIGSv 5 and 6, would be cmbeddcd in the concrete with the cover caps shown therein in place. After setting of the concrete all the caps shown would be removed. The bolts 92 and 93 contained therein positioned appropriately and thence secured by suitable nuts to the accommodating holes in the machine base. At which step in the procedure the grout would be poured into the hollow of the tubular members 85 and 86, via the passageways 80 and 8| to secure and coupled the entire assembly as described above.
