purlins and covering material.
bers and arrangements of the sectional units.‘
Referring to Figs. 1 to 3, the building illus
trated represents an airplane shed or hangar,
the plan dimensions being for example 175 feet
long and 95 feet wide, giving a clear inside width
of about 90‘ feet; with these dimensions the 35
building may comprise ?fteen complete roof
arches A, with ?fteen pairs of wall stanchions B,
providing fourteen bays 0, each 12 feet 6 inches
long, two such bays being represented in Figs.
2 and 3.
Each wall stanchion is shown as built
up of three similar sectional, units a, giving 'a
clear height of about 25 feet inside the building.
Each roof arch is shown as built up of ten simi
lar sectional units a, ?ve on each side of the
centre line of the building at the corners, where
the roof is connected to the walls, slightly modi
?ed sectional units b are provided, for a purpose
hereafter ‘explained, these corner units being con
nected between the outmost sectional units a- of
the roof arch A and the topmost units a of‘the
wall-stanchion B.
50
.
The main sectional units a, when assembledtoé }
gether to form a main arch or principal A of the
roof, have their abutting ends substantially ver- ‘
tical while their top and bottom membersare
55
2
2,124,242
inclined at a relatively small angle (for example
15 degrees) to the horizontal; in order that sec
tional units a of the same form may serve for
vertical side wall stanchions B of the structure,
in which the abutting ends will be inclined to the
horizontal, the foundations 0 upon which the
walls rest are each given a slightly oblique top
face, inclined at the same angle as the main arch
or roof principal A, the substantially vertical
10 rhomboidal units of the walls resting endwise on
these oblique faces.
The sectional units a are arranged for bolting
together at their meeting ends directly or by
‘means of cover straps across the joints, or for
15 assembling in any other convenient manner, the
spacing of the bolt holes or the like being uniform
in all the units as Well as in the foundation mem
bers c on which the walls ‘are ‘mounted; similarly
spaced bolt holes or the like may be’ provided at
other points of some or all of the units, for ex
ample to allow of securing the outermost units
of fth’eroof'principals‘ in suitable angular relation
to the topmost units of‘the walls, so that the
roof can rest directly upon the top of‘the wall at
25
each side.“ Preferably,'however, a modi?ed form
of ‘unit b is provided for the corner-connection of
the roof to the walls or for the connection between
other sectional units in angular relation.
‘ The'preferred construction of the main sec
39 tional units a is shown more clearly in Figs. 4 to 6,
‘ where it" can be seen. that‘the unit is of rhom
boidal shape, the ends ‘being substantially ver
tical (in the position'occupied when forming a
sectional‘ unit of the‘ roof arch) and the top and
bottom‘lon'gitudinal members or booms being in
clined atlan angle of about 15 degrees to the hori
zontal. " The 'unit ~is built up by b'olting together
a number of rolled steel angles, vcut to suitable
lengths, comprising end members a1, longitudinal
members or booms a2, arranged in pairs, and di
agonal stays as. The members a1 a2 are secured
together'by means of angle plates w1E at each
corner of the unit, one of these plates being bolted
between‘ the two' ‘longitudinal members‘ a2 and
45 having the end of the member a1 bolted thereto;
‘ the second'an‘g‘le plate a4 has ‘its side flange ex
tending in the reverse direction. At each end of
the unit, the sidel?ang'es of- the two angle plates
a4 at'the top‘ and ofrt'he two atxthe bottom are
flush, with the ?ange of the angle a1 so as to
‘ form" an 'end'surface'for jointing to an adjacent
un‘it’f'by ‘bolts passing through holes in these
?anges.‘ The booms a2 may also ‘be formed with
correspondingly arranged bolt holes, so that two
55 such units can be bolted together in angular rela
‘ tion as analternative to ‘the end-to-end relation.
The modi?ed corner unit I; (Fig. '7) differs from
the standard
a mainly in that its lower longi
tudinal member or boom 1)2 is cranked or offset to
60
provide end‘ portions of, different depth; one end
121 ‘is of. the same depth as the end a1 of the
standard unit, but the other end 123 is made
65
stanchion unit a, or in a reversed position, with
the end b1 resting on the top of a wall-stanchion
unit and the face b4 bolted to the vertical end a1
of a roof principal unit a. The corner unit also
provides a slight increase of strength, as com
pared with the bolting of a standard roof unit a
upon the top of a similar Wall-stanchion unit a,
by reason of the stiffening due to the extra depth
at the corner where the maximum stresses in the
frame occur.
The corner units may also be em
ployed for connecting sectional units in angular
relation at other positions, for example for the
10
ridge connection of the two principals of a roof
arch, twov such units being inverted and bolted
together at their deeper ends b3, and the other 15
ends 121 being bolted to the ends a1 of the‘main
units forming the roof principals.
It will be understood that the sectional units
may be built up by bolting, riveting or welding
together any suitable rolled steel sections to form
a girder structure of rhomboidal shape, and that
the units may be composed of metal sheets or
pressings built up in any convenient manner.
For example, Fig. 8' shows the corner unit b
formed by pressed steel booms b2 of channel sec
tion having their side flanges connected together
25
by‘parsnei steel plates b5 cut out to provide
apertures of which the edges are reinforced by
continuous lips b6; flat steel plates are welded
between'the extremities :of the booms b2 and 30
platesb? to ‘form the ends b1 b3 of the unit, and
also at intermediate points of the length to form
diaphragms b7, stiffening webs I)8 being welded
between the plates b5 to’ connect the lips I)6 with
the booms 62. or' diaphragms b".
Each- of the wall stanchions B has its lowest
sectional unit a bolted down upon a foundation
member‘c (Figs. IQ and 11) havinga pair of
oblique steel‘angles c1 secured thereto, the top
faces “of the‘ angles 01 having the same inclina
tion as theroof principals, viz. 15 degrees, so that
35
40
when the unit a is laid in a vertical position upon
this member 0, its end a1 will rest evenly upon the
oblique angles (31, upon which it will then be se
cured bybolts passing through bolt holes provided
to’ correspond with those in the end (11. The
member 0 may consist, of a steel plate, having the
oblique angles c1 riveted thereto and itself riv
eted in'place between two channel steel bearers

secured to’ the sleepers e;; alternatively the sleep
to pairs of pressed steel sleepers e, the whole
ers e may be held down by sand bags ?lled on the 55
site and laid across the sleepers.
, The severalmain arches A and wall-stanchions
B thus constituted'are connected together in the
longitudinal direction by purlins g and external
side rails h respectively, arranged at the points of
60
connection of‘ theends a1 of the main units a,
and also at intermediate points half-way along
deeper, for example about half as deep again; the
offset face I)? of the deeper end, extending par,
allel to the top boom, is made of width equalto
the depth of the end b1, and formed with corre
spondingly arranged bolt holes, so that this unit

12), the extremities of the purlins being slotted
transversely at g1 so as to engage with bolts 2'1
projecting from the sides of the saddle blocks; the

supported by pressed steel sole-plates s, to the
number for example of four to each length of
track; the sole-plates are secured to the track by
spot-welding ‘and are anchored by angle-iron 10
stakes s1 driven obliquely through holes 82 in the
?at ends of the plates, the earth being excavated
to allow the laying of the track and then re
placed level with the latter. The lower ends of
the bars 0 are ?tted with socket sleeves o2 carry
bars o from being blown inwards or outwards of
the building by wind pressure. The ‘sleeves o2
are provided with hand-operated drop bolts 05 20
braces k, preferably adjustable in length to allow

The roof and walls may be covered with canvas,
but are preferably covered with galvanized sheets

vented from crowding too closely together as they
run along the overhead track p by means of stops 25
or bumpers o6 fastened near their top ends, these
stops abutting together as shown in dotted lines
in Fig.- 15.
The opening and closing of the doors may be
operated by wires t attached to the bars 0 ad 30
jacent to the center of the doorway, by knotting
to eye-bolts t1 near the top ends of these bars,
the wire passing freely through the eye-bolts of
the other vertical bars; preferably one endless
length of wire is employed at each doorway end 35
of the building, the overhead track rail 10 be

pair of vertical pulleys u u1 (Fig. 18) and a hori
zontal pulley. 11,2 (Fig. 19) so that the wire is
looped over the doorway with a crossing at the
sheets. Alternatively, as shown in Fig. 2 in the
case of the wall-covering sheets, the end lap may

than two sheets at any point. Transparent top
panels m, consisting of oiled fabric or like mate
rial, may be ?tted to the sides of the shed, as
shown in Fig. 9, in order to give light to the
55 interior.
Doors may be provided at either or both ends
of the building, these doors being preferably
divided at the center; in the arrangement shown
in Figs. 1a and 13, the door 7!», which extends
60 across one half of the doorway, is constructed
of canvas or like material, sitffened by vertical
steel bars or arranged to travel upon rollers 01
along an overhead track 12‘ formed by a T~section
member mounted across the doorway, so that the
65 canvas doors or curtains can be run aside, the
bottom ends of the bars 0- being adapted for ?x
ing to screw pickets or the like when the doors
are shut. The track-member p may be mounted
70 upon hangers 121 above the doorway, these be
ing steadied by oblique stays 122 (see Fig.‘ 13)
anchored to the purlins g in the end bay of the
roof. A canopy q is provided across the top of
the door opening, covering in the hangers p1 as
75 well as the‘ space above the track-member 10 up
tion as required by appropriate movement of the
winch handle 01. '
The doors may be made of material other
than canvas or the like, particularly where 55
danger of ?re exists; for example, as shown in
Fig. 23, the vertical bars 0 may be hinged at 10‘1
to steel slats to which are themselves hinged to
gether at wz, the hinges being disposed at inter
vals of ?ve feet for example along the edges of 60
the bars and slats. The hinges may be either
inside or outside the shed, and they are ar
ranged -to limit the unfolding movement so that
the slats cannot reach a straight-line position.
When the door is opened by bringing the bars 0
together by means of the operating wire, the
slats fold up together as shown in dotted lines
on the right of the ?gure.
'
The erection of the shed can be effected by
assembling the several units to form the stan: 70
chions and raising the latter by hand; the roof
principals, also formed by assembling the re?
quired number of units a, with or without corner
units b, to make up the two halves of each arch
A, are then hoisted into position by suitable 75
4
2,124,242
tackle, employing a number of assembled units a
or other members to constitute a pole or derrick.
. By. way- of example, the main units-a may be
roof to one of said'walls, said member comprising
a straight longitudinal boom, a second, longitu
dinal boom cranked intermediate of its ends, two
8>feet long, 2 feet 3 inches deep, and 6 inches
wide; thus three assembled units a will make
up a stanchion 24 feet high, and ?ve assembled
units a will make up a roof principal or girder 40
feet' long, allowing with the addition of the
ends of different lengths connecting said booms,
corner units 1) for a roof span of about 95 feet,
10 as already mentioned in relation to Figs. 1 to 3,
stanchions and roof principals forming a series
of parallel frames, each of said side wall stan
chions and roof principals being formed by the
height can be reduced to about 21 feet near the
walls. The dimensions of the units may them
25 selves be varied from those mentioned by way
of example, the units being made of lighter
design (for example 18-inches deep) for spans
up to 65 feet and of heavier design (for example
3 feetdeep) for spans over 120 feet.
The invention may obviously be applied to the
construction of portable or “sectional” buildings
to be used as-garages for motor trucks or the like
or as store-sheds for any purpose, whether tem
porary or permanent.
