No. 214,226, filed Dec. 30, 1971, now abandoned.
- the invention herein is concerned with apparatus which is intended to be installed in the deck of a building during the construction thereof to provide depending hangers below the deck.
- apparatus which is intended to be installed in the deck of a building during the construction thereof to provide depending hangers below the deck.
- hanger inserts of the invention one may support pipes and conduits, automatic sprinkler apparatus,
- deck construction is a type of construction which is extensively.
- the floor of one level isdefined on the upper surface of a givendeck while the ceiling of the lower level is defined by the lower surface of the same deck.
- Fluted or corrugated sheet steel is utilized as a floor base and filled with a substantial layer of concrete poured in situ.
- Utility service conduits are laid insuitable formations of the sheet steel member prior to pouring concrete upon the upper surface .of the member. There may be outlets for these conduits on the upper surfaces of the concrete layer which are prelocated in the concrete or otherwise identified to be used at a later time.
- the bottom of this layer of concrete is in intimate contact with the steel base whose underside is exposed below'as the ceiling for the lower level.
- the resulting deck structure is strong and ,substantiallyfireproof.
- Different means are-utilized to assemble the several partsof the hanger so that it may readily swing or yield and return to its original vertical position perpendicular to the horizontal sheet steel member even though struck or moved by a workman or an object prior to thev pouring of the concrete.
- the upper portion of the boltlike member is permanently embedded I and the lower end thereof extends below the sheet steel member and is available for securement of structural members thereto.
- Either a stud arrangement or a I threaded socket may be provided.
- FIG. 1 is a fragmentary sectional view taken through the latter being shown, for the most part, in elevation;
- FIG. 2 is a sectional view taken through the hanger insert of FIG. 1 generally along the line 2-2 and lookfeet the installation from below after the concrete has I set. This is a difficult and expensive technique.
- the invention contemplates a type of hanger insert which obviates some problems arising in any attempt to provide hanger inserts for pre-installation.
- the insert must be simple andstrong so that it can be installed effectively and easily. Also, it must be economical and result in a strong installation below the deck after the concrete has set.
- the insert must not readily be pulled out or permanently bent over prior to the pouring of the concrete. This is important because until the concrete has been fully poured, workmen may step on the inserts,
- the hanger insert comprises an elongate boltlike ing upwardly;
- FIG. 3 is a perspective view of the sheath member of the structure of FIG. 1;
- FIG. 4 is a fragmentary view illustrating a modified form'of the invention using a sheath member which is different from that illustrated in FIG. 1;
- FIG. 5 is a side elevational view with portions in section as showing a further modified form of the invention.
- FIG. 6 is a bottom plan view of the sleeve member of FIG. 5;
- FIG. 7 is a sectional view through the sleeve member of FIG. 6 taken generally along the line 77 and in the direction indicated;
- FIG. 8 is a view similar to that of FIG. 1 showing a further modified form of the invention.
- the hanger insert of the invention is designed to be installed in decking of the type which involves poured concrete prior to the pouring of the concrete so that the setting of the concrete will permanently anchor the insert in the deck.
- FIG. .1 there is illustrated a portion of a steel floor deck comprising a horizontal'sheet steel member 10 having a layer of concrete 12 of substantial thickness above the same and in intimate contact therewith.
- the hanger insert of the invention is designated generally by the reference character 14 and is shown partially above and partially below the horizontal sheet steel member 10.
- the insert 14 comprises an elongate boltlike member having an upper cylindrical body portion 16 and a lower cylindrical body portion 18, the lower body portion 18 protruding below the sheet steel member 10 maydrop; t 1 After theinsert has 1A sheathmember 28 is provided to securethe boltlike member to th e'sheet steel member 10; The sheath member28 is best illustrated in FIG 31.
- lt is a sleevelike' structure formed from thin sheet spring-steel and has a' cylindrical body 30o'pen atthe bottom as shown at132 and'providecliwith an axial; s arse therehy givingthe sheath member hodilyresilience; At its upper there i v are providedflangelike ears'36'jand aplurality ofispring L finger-s38 spacedrbelowthe" 6211 8436.
