INSERT FOR CONCRETE CONSTRUCTION.
Application filed May is,
T 0 all 1071MB it may concern:
Be it known that we, EDWIN V. Knzmns, and ARTHUR C. VVALwon'rH, (in, both citizens of the United States, residing at Melrose and Newton, respectively, county of Middlesex, and Commonwealth of Massachusetts, have invented acertain new and useful Improvement in Inserts for Concrete Construction, of which the following is a specilcation, reference being had therein to the accompanying drawings.
The invention relates to a new and useful improvement in inserts particularly intended for use in buildings made of concrete and suitable for furnishing meansby which to attach fixtures to the walls or ceilings of the building, one instance of such use being to serve as a pipe hanger. In buildings of concrete construction, it is impracticable to attach the device directly to the concrete wall or ceiling after the building is completed and the concrete has hardened. For this reason it is desirable to have the insert attached to or connected withthe wall or ceiling at the same time and in connection with the construction of the wall or ceiling by embedding in the concrete at least a portion of the insert. It is preferable to have the device made in two parts, one part, which is the insert, beinga fixed element embedded or anchored in the concrete so as to hold it securely against displacement or beingpulled out by the weight that is suspended from it, and the other part being a separable element such as a bolt which may be detachably connected at one end with the insert, the other end being adapted to form a support or holder for the object which is to be hung from it. For this purpose the insert is so constructed and embedded in the concrete as to provide an entrance passage to it for the separable element, the connecting portions of the two elements being so constructed that the separable element may be easily engaged with the insert and locked in connection therewith in such manner that there will be no danger of accidental displacement and yet so that it may be easily removed when it is desired to replace one separable element by another. It is also desirable that the outer end of the insert shall not protrude beyond the surface of the wall or ceiling.
Our novel insert is so constructed that there will be a sufiicient body of concrete un der and adjacent the parts of the insert so Specification of Letters Patent.
Patented Aug. 2, 1921.
1919. Serial N0. 297,987.
that the load will be taken by the concrete as well as the metal of which the insert is composed and therefore the insert may be made from thin metal which would not in tself be sufficient to carry the load which is imposed on it. Furthermore, if in time the insert should rust out, the concrete will still carry the load safely. v
The invention will be fully understood from the following description when taken n connection with the accompanying drawings, and the novel features thereof will be pointed out and clearly defined in the claim at the close of this specification.
In the drawings, Figure l is a vertical sectional view showing an insert embodying the lnvention, inserted in a wall of concrete construction.
Fig. 2 is a section on line 2-2 of Fig. 1.
Fig. 3 is a bottom view of the fixed member of the insert as it appears when embedded in the concrete, showing the slot in the under side.
Fig. 4 is a view in elevation of the fixed member of the insert before being embedded.
Fig. 5 is a plan view, and Fig. 6 an end view of the fixed member.
Fig. 7 is a vertical sectional view showing the fixed member of the insert attached to a wooden form by nails to hold it in placewhile the concrete is being poured and setting, the form to be afterward removed and the nails cut off below the concrete.
For convenience of description, the insert ill be referred to as though connected with a ceiling or other horizontal wall, although it is to be understood that it is adapted for use in connection with a vertical wall as well as with a horizontal wall.
Referring now to the drawings, the insert A is a hollow shell composed of two parts 0 and 65 made of some suitable metal, as for instance, cast iron or wrought iron, the walls of which may be relatively thin and weak. It has an open slotted mouth on the under side as shown in Fig. 3, having a relatively long and narrow portion 2, said slot being broadened out on both sides at one end forming a wide portion 3, so that the 'slot is somewhat T or keyhole shaped. The recess or chamber in the interior of the insert is shaped in cross section like the slotted mouth. The wide portion of the slot extends along one end up to the top of the shell ano thence along the entire top of the shell as shown in Fig. 1, forming a passageway of sufficient width to receive the broad side of the head 4 of the separable element or bolt B while the shank 5 of the bolt extends out through the narrow portion 2 of the slot.
Preferably, the wide portion 3 of the slot is curved where it merges from the vertical portion to the horizontal portion as shown in Fig. 1 so as to afford ready passage for the head of the bolt while it is being introduced from the entrance end and moved up into the horizontal portion of the slot and to enable it to readily turn the corner. At the junction of the narrow portion2 of the slot with the wide portion of the slot there will be formed shoulders 6, 6 one on each side which form seats for the flange portion of the head 4 of the boltB.
The narrow portion 2 of the slot in the insert has two vertical parallel walls 7, 7 and the broadening out of this portion at one end and the top to form the widened portion 3 of the slot, gives a wing formation at the end and top on the outside of the casing which of itself would form an anchor when the device is embedded in the cement. Preferably, however, there are formed additional flanges 8, 8 one on each part. c and d of the insert which distribute the load. On the bottom of the insertare formed two pairs of lugs 18 one on each part c and (Z to receive nails or tacks 11 which are driven into the wooden form 9. After the cement has been poured and has become set, the wooden form 9' will be removed and the portions of the'nails ll'which entered the wooden form 9 and which will be left projecting after the wooden form has been removed, willthen be cut off or broken out of the concrete so that the ends of the nails will not project below the surface of the concrete as shown in Fig. 2.
The bolt B can be introduced into the element A by'holding it in a substantially horizontal position while the head is bein introduced into the lower end of the broad portion 3 of the slot, then while grasping the bolt at its outer end, the shank of the bolt being of sufficient length to extend below the ceiling when in place, the head of the bolt may be swung upward following the course of the broad portion of the slot 8 until the head of the bolt reaches the horizontal portion of the slot 3. It may be adjusted in any part of the horizontal portion of the slot which is desired. The lower end of the bolt as shown in Figs. 1 and 2 will then hang down through the bottom of the narrow portion of the slot.
The head, however, will be seated on the shoulders 6 so that there is no danger of its becoming pulled out by a downward strain. The downwardly projecting lower end of the shank5 ofthe bolt may be formed suitably for connection with whatever object is'to be suspended from it. It may be formed with a loop for a pipe hanger or it may be screw threaded so that the object may be screwed on to it or formed in any other suitable way to make proper connection with the object that is to be suspended.
comes to the curved bend in the head passage, then the bolt can be tipped so that the flange of the head will follow the course of-the passage around the bend and thence down and out at the bottom.
From the foregoing, it will be seen that the load carried by the insert is transmitted to the concrete surrounding it' and that the security of the object connected to it does not depend upon the strength of the metal composing the insert. On the contrary, the load is carried by the masses of concrete at and b which'are directly below the sides of the chamber 3 and'the flanges 8, 8, and consequently the walls of the insert may be made very thin. This makesit possible to make the insert from stamped metal if desired in which case it will be necessary to make the insert in two parts which are afterward secured together.
What we claim is:
An insert for use in concrete building construction to hold a headed member, said insert comprising a shell having an entrance opening which extends up from the bottom for the passage of the headed member, said opening-being widened at one end to form a T-shaped passage, said widening continuing up on one side of'the chamber and thence across the top, forming at the top horizontal wing portions to receive and support the head of said member, the inner face of the wall of the horizontal wing portions of the chamber extending laterally beyond the plane of the outer face of the natures.
