The connection is such that it allows and pivoted at H to the sides of aslot formed in 5 the two members to move relatively in the manthe end of the beam, the end of the latter being ner ofa sliding hinge which facilitates erection relieved a-t l8 to provide clearance for erection and and dismantling as hereinafter described. The 'collapsingand also recessed at l8a to support the ends of thebeam are provided with supporting adjacent end of the lug l6 when the beam is in lugs as usual but these lugs are-hingedly attached position in the work. The hinges are preferably to facilitate the removal of the beam fromthe so arranged that the lugs cannot pivot beyond a finished work. position substantially level with the top of the To enable the invention to be fully understood beam. The pivot pin Il may be left short in the it will now be described by reference to the achole on either side or alternatively a hole or lug is companying drawings, in which: provided as shown at 2 9 and 30 respectively for Fig. lis an elevation showing a support or beam the purpose of supporting the stirrups carrying 5 the centering of the supporting beam in cases where the floor is suspended from a cross beam made up of a rolled steel joist encased in plastic material or the like construction. When the beam has been erected in position as indicated in Fig. 1 the two members Ill and ll are locked together by suitable means here shown as clips each con.- sisting of a toggle lever l9 pivoted at 20V to the flange of the member l and engaging one end of a link 2i shaped to embrace the flange of the member 5 l on each side. A lug or eye 22 is secured to the member ill for attachment of a tackle 2.3. and several such lugs may be provided if desired.
A beam constructed as above described may be used in constructing a iloor as follows:
Referring to Fig. 9. The two members It), II having been assembled by nesting the one within the other and engaging the rollers M in the channels l3 the outer ends of the members are raised to the abutments 22a. of the new floor level. and the hinged lugs Eli are held in position in said abutments. This causes the two members to move relatively in the manner of a sliding hinge as shown. The tackle 23 is then applied and the inner end of the member H is raised until the two members are in alignment; the toggles l9 are then adjusted to hold the two members rigidly together (Fig. 1). The floor is then applied on the upper side of the beam and when it is finished the toggles are unlocked allowing the two members of the beam to be pulled down again into the position shown in Fig. 9 and finally the hinged lugs i6 are prised clear of the abutments and the beam is removed.
Figs. 10 and 11 show the application of the invention to a floor construction wherein the whole of the centering is slung from a cross beam such as a steel joist 4t embedded in some plastic material placed at the same time as the floor. In this construction an endless stirrup 32 of steelbar is placed over the joist ll? and the lugs it of the members Ni, ii are inserted in the loops of the stirrup 32 as shown and if necessary bound in place by light wire ties passed through holes formed in the lugs. The shuttering 34 of the joist iil is then placed in position and held in place by a stirrup 35 supported in holes 3i] formed in the members ill, H or if desired the holes 30 may be replaced by lugs over which the stirrup is hooked.
In disassembling the lugs 16 are prised clear shearing the light wire ties, if any, the stirrup 32 being left buried in the plastic material. shows the plastic floor i! in position.
Fig. 6 shows the invention applied to a curved beam, the members 10, H and lugs l6 being as described with reference to Fig. 1 except that the members Ni, ii are curved and the lugs it do not pivot beyond a position substantially level with the ends of the members l6, ll.
Fig. '7 shows the invention used to support a floor made of hollow clay or precast concrete tiles as with the main beams 25 of plastic material cast in situ. A series of beams A constructed according to the invention are indicated diagrammatically.
Fig. 8 shows a series of beams A supporting a floor consisting of a solid slab 26 of plastic material cast in situ, the spaces intervening between the means being supported by metal or wood forms 2? supported at the joint planes by wood or similar chocks 28 suitably spaced and resting on the out-turned flanges at the bottom of the webs of the beams A. 7
It will be understood that a beam constructed as hereinbefore described is rendered incapable Fig. 10
of sagging by the use. of the locking clips referred to. The beam does not depend upon telescoping for development of the necessary reaction to the bending moment and in Which the metal is not most economically disposed for this purpose and in addition the beam breaks contact with the plastic material on disassembling by tension and not by shearing or sliding. Further the beam can be erected from the floor below that to be built, which is a great advantage in practice. The improved beam is preferably formed from two inserted channel members of rectangular crosssection arranged with bases uppermost and having deep sides with out-turned flanged edges but other forms of open hollow section or sections with out-turned or plain edges may be employed. The webs of the channels can be pierced or latticed for lightness if desired, but the section should be so shaped that it is symmetrical in reard to a vertical central plane so that it is centrally loaded by the weight coming upon it.
Other forms of sliding pivotal connections may be employed for the members forming the beam and a beam may consist of more than two members. Various means may be designed for locking the members of the beam together when in the working position, and bolts may be used if desired.
Although the improved beam according to the invention is most usefully applied to the construction of floors and the like, it may be used for the supporting of vertical surfaces thus acting as a Walling. In its curved form the beam may be used in the construction of arches and the like.
I claim:
1. An adjustable and collapsible support for use as a temporary support in building operations comprising two interfitting sheet metal members of open hollow section, a groove in one of said members, a fixed pivot on the other of said members engaging said groove and providing a sliding pivotal connection between said members and means for locking the said members together when the support is erected in position.
