SCAFFOLDING FOR GENTEBING AlNZD THE LIKE.
Application filed April 23, 1921. SerialNo. 463,880.
I '0 all whom it may concern:
Be it-known that I, J O-SEPH R. S-IaoRE', a citizen of the United States, and ttIQSldBIll? of Newark, county of Essex, and State of,
New Jersey, have invented certain new and useful Improvements in Scaffolding for Centering and the like, of which thefollowing is a specification.
This invention relates to an improved support or scaffold for temporary use, such as is employed for supporting centering of concrete structures, but, of course, beingadapted for use with tile or othermaterialsnecessarily supported while setting or being otherwise secured in place. 7
The advantages of the structure are that it requires much less lumberthan is used in the old form of centering support, that less labor and time are used in erecting and removing it, that it insures greater working space below, that it permits a greater num ber of re-uses, and that it is very substantial for use under super-imposed loads.
The invention includes a series of girders and beams which-are each a unitary structure and so constructedas to withstand the required load, done by providing trusses on girders and beams so-as to give the required rigidity and to-provide a plain top surface, these being supported on suitable uprights.
The invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view, broken away to show a scaffolding made according to my improved invention, illustrating different methods of arranging the timbers. Figure 2 is aside view of one end e f-a girder or beam, and Figure 3 is a similar view of a modified form of construction. Figure lis a perspective view showing a beam in section and illustrating one form of strut. Figure 5 is a face view of the bottom of a modified form of strut, and Figure 6 is a perspective view showing some of the parts in section and illustrating the arrangement of the parts adjacent to a column.
The old method of erecting scaffolding for centering and like purposes has been to arrange a large number of uprights, which are suitably cross-braced and'to which horizontal beams are nailed or otherwise secured, and then the boards for forming the center-- ing to support a cement, tile or similar ceiling or floor placed on top of these. The old form necessitated a large number of uprights in heavy structures, soclose together, in fact, as toprovide but little Working space underneath, this being confined usually to aisles .or longitudinal spacesibetween rows of uprights. j i
When the workhad been; completed and the whole structure had tobe taken out, in
the old. form in the knocking down of: the scafiolding a great deal of lumber-Was destroyed,.which is. a considerable factor because so much-lumber is used in ythejstrud ture itself. With this large number ,of'uprights, especially on'ground floors, they; had been placed close together, which, ofcourse, makes it necessary. to putsome of them-0n the ground and not on the cement footings of the structure, and in cold weathe-r,.where itis necessary to place braziersor-firesto keep the cement from freezing, the thawingthat takes place underneath many of: the uprights permits them to settle into the-ground,
coNcnErE and the centering consequently settles, and
there is an unevensurface at the top of the scaffolding, due. to thissettling.
In my improvedscafioldihg theuprightsare placed much-further adapt, inmost cases it being possible'touse .on the bottom or ground floor the cement footings of the columns and bridge the spaces between the uprights by beams, which in themselves are unitary structuresand are laid onthe up rights, and then, if necessary, in turn are i used as girders to support transverse beams bridging the spaces between the girders,-and there is but little nailingto be done, and when the device is toibei knocked downand removed there is very little spoiling or, destroying of lumber, and there is much less lumber andlabor used in the erection, removing and re-erection than with the old form of scaffolding.
The main vertical support of the scatfold is usually in the form of uprights 10, it being usual to employ joists or studding commensurate in size with the load to. be carried, and suitably braced by boards '11 which are usually nailed to the uprights and around the place where the concrete columns arev to rise. Extending from one upright to i usually provided with turn-buckles by means of which they can be given the proper tension, and by means of which any shrinkage in the beam or other looseness due to through said chamtered ends and provide them, on their outer ends, with nuts 16 hearing against the bearing plates 17, as will be seen more particularly from Figures 2 and In the case of girders I usually provide double tension rods 14:, in this case the hearing plates 17 being replaced by plates 18 which project beyond the side edges of the girder and through which projecting ends the tension'rods pass and are secured.
Spanning the space between the girders I arrange the beams 19, which are trussed similar to the manner in which the girders are trussed, in the shorter type using only one strut-placed in the middle of the beam and having the tension rod bearing on the under side of this strut, as will be seen from Figure 3.
Figure 4 shows a detail of a strut, this strut having a channel 20 at the top into which the girder or beam sets, thus preventing lateral motion of the two parts relative to each other, and the foot 21 is recessed to receive the tension rod 14:.
In Figure 5 I show a wooden strut 22 which is provided with a foot 23 channelled to receive the bottom end of the strut andhaving its lower part perforated to receive the tension rod or tension rods lat. It will thus be seen that each beam or girder is a unitary structure in itself, and as a trussed element it v is sim lv laid in its pro er lace in the scaf- U i l vfolding, is placed in position without the necessity of nailing it and is consequently easy to remove, and they are not bulky, so that many of them can be transported in a motor truck or the like.
On the top oi the beams I elace the 'cen tering, usually consistingof boards 24: which form a surface on which the concrete, tile or other platform, such as a ceiling or under surface of a floor, can be supported until it sets and is able to maintainitselt in position. V v
In Figure .1 I show also the cooperation of this form of scaffolding with the forms used around columns, these columns being shown in dotted outline at 25, and the surrounding timbers to maintain the scaffold are shown in the immediate foreground in Figure 1, this portion of-the framework be ing of the usual type.
If desired, I may provide the uprights with broader tops as by providing each with a bracket 26, shown in Figure 2,01" a cap 2'7, shown to the left in vFigure 1, which is extensive enough to permit the setting of the ends of tour beams on the top of one upright. o
I claim;
1. A scafioldingfor supporting centering comprising uprights, readily removable trussed girders of nonecollapsible form supported on the tops of the uprights, and readily removable trussed beams of non-collapsible form supported at their ends on the girders, said structure permitting the plac+ ing of the uprights only on the footings of columns, and centering arranged on said beams to hold a cement fioor thereon and to prevent said cement from contacting with the beams or girders. r
2. A scaffolding for centering comprising a substantially rectangular framework of trussed girders, a set of trussed beamslsupported at their ends on the girders, and uprights arranged only at the ends of the girders and supporting the same, whereby the uprights can be located on the footings of columns, and whereby the intermediate space between uprights can be leftclear;
In testimony that I claim the foregoing, I have hereto set my hand, this 22nd day of April, 1921.
JOSEPH 1a. SHORE.
