6 Claims.

Our invention relates to a rigid frame building and method of making the same.

Pre-fabricated sectional buildings for various uses are known to the art. These comprise frames including familiar trusses formed of a number of small members triangulated to make the truss.

One object of our invention is to provide a rigid frame sectional building of more economical construction than the conventional type,

Another object of our invention is to provide a rigid frame sectional building which eliminates the flimsy X bracing, which is customarily used in the prior art in the plane of the lower chord of the trusses.

Still another object of our invention is to provide a rigid frame sectional building providing additional head room while avoiding the awkward and wasteful truss construction.

A further object of our invention is to provide a rigid frame sectional building which may be more expeditiously shipped, fabricated and erected.

A still further object of our invention is to provide a sectional building which is of more rigid construction than has heretofore been achieved.

Other and further objects of our invention will appear from the following description.

In the accompanying drawings which form part of the instant specification and are to be read in conjunction therewith and in which like reference numerals are used to indicate like parts in the various views; I

Fig. 1 is a perspective view wtih parts broken away showing a rigid frame sectional building embodying the construction of our invention.

Fig. 2 is an elevation showing two elements of the rigid frame.

Fig, 3 is an elevation showing one of the elements of the rigid frame which when joined to the elements shown in Fig. 2, will make one complete transverse rigid frame.

Fig. 4 is a plan view of an I-beam showing the lines of cutting to produce columns used in our invention.

Fig. 5 is a sectional view taken on the line 5-5, Fig. 1.

Fig. 6 is a sectional view taken on the line 6-6, Fig. 3,

Fig. 7 is a sectional view taken on the line I-I, Fig. 3.

A rigid frame building is one which obtains its rigidity by virtue of immobile joints, in distinction to one in which the rigidity is imparted by triangulation of smaller steel members to form trusses.

The transverse members of the building are virtually integral beams formed in the desired shape. Each transverse member in the rigid frame construction is called a bent. Each bent comprises two columns which are rigidly connected to knees or haunches, to which the roof beam is secured to the columns.

Referring now to Fig. 2, it will be seen that column I supports a haunch 2, which is welded or otherwise integrally secured to the column I. The roof beam is composed of two members 3 and 4, which may be conventional I-beams, welded at 5 and reinforced by an angle plate 6. For ease in transportation,- we form each bent of three pieces, two members each comprising a column I and a haunch 2, and a roof beam member. Each haunch 2 is drilled with holes 1. Each end of the roof beam is drilled with holes 8. Plates 9 are adapted to be secured to the roof beam end and haunch to connect the same by means of bolts or rivets III. The junction is made near the point of inflection which is the point of zero moment. In this manner we are enabled to pre-fabricate a bent in three sections for ease in transportation, and yet retain the necessary rigidity for a rigid frame building. It is to be understood, of course, that the junction between the roof beam and the haunch may be made in any other suitable manner as, for example, by welding or'the like.

The haunch 2 is formed of a web II and upper and lower flanges I2 and I3. The roof beam 4 is of I-beam cross section, The haunch 2 is welded to the column I and a web It is welded to the column, as can be readily seen by reference to Figs? and 3. This web adds strength at the point of increased stress.

The columns I, of course, carry a compression load. They carry, too, a moment which increases upwardly. For this reason we form our columns I with a web I5 of increasing width. In forming our columns, we take an I-beam I6, shown in Fig. 2, and cut it into two portions along the line H, thus forming two columns from a single I-beam. Each member formed by cutting the I-beam I6 into two parts, is provided with only one flange III. In order to increase the strength of our columns and at the same time provide means for securing the sides of the building between bents, the webs I5 are provided with a plurality of openings I9, as can be readily seen by reference to Figs. 1, 2 and 3.

The side wall sections adapted to be secured between bents-are made up in one piece and shipped as such, A cross sectional view of a section is shown in Fig. 5, in which a panel 20 of galvanized corrugated sheet metal is spotwelded along its edges to angle members 2| and 22 respectively. The angle members are the same length as the height of the web I! of a column. The angles 2| and 22 have one web thereof spotwelded to the sheet metal panel 20. The other webs 2| and 22', respectively, are provided with holes corresponding to the holes I9 of the webs l of the columns When two adjacent panel sections 20 are aligned on each side of a web l5, they may be bolted to the web l5 by bolts 23, as can readily be seen by reference to Fig. 5. When the panels are securely bolted in place, each column I will then become a tapered built-up I-beam column. It will be seen that our construction at once secures the panels in place and forms the I-beam,

columns of the bents.

Doors and windows as desired are installed in the panels 20 in the shop. By reference to Fig. 1, it will be seen that a window 24 is provided in the panel section 20.

Purlins are made of standard mill-shaped channels 25 and bolted to the top flange of the roof beam portions of the bents. The purlins 25 support a galvanized sheet metal roof 26, as can be readily seen by reference to Figs. 1 and 2.

Crossed rods 21, which can readily be seen in Fig. 1, are secured in the plane of the purlins and necessary bays to give rigidity.

stringers 28 may be welded to the angles 2| and 22 of each panel, and the corrugated sheet metal 20 spot-welded to the stringers to give the panels the desired rigidity.

The column portions of the bents are tied together by stringers 29 and form the bottom margin of each panel. It is understood, of course, that the bents may be supported by any suitable foundation, such as concrete piles or concrete walls.

It will be seen that we have accomplished the objects of our invention. The panel sections, bent sections, roof purlins, roof sheeting, and rods may be easily shipped to any desired location, and buildings of various sizes may be readily constructed in the field from the pre-fabricated parts.

The length of the building is determined by the number of bents employed. The distance between bents is governed by the width of the panels.

Buildings according to our invention are more economically constructed than those of conventional construction. Our construction eliminates the flimsy X bracing, such as is usually used in the plane of the lower chord of regular trusses.

Our construction enables additional head room to be obtained, and produces a more modern building of neater appearance. Our construction, furthermore, gives a building a. more rigid character than has heretofore been thecase with sectional buildings of the prior art.

If desired, insulation may be placed between the stringers 28 and between the purlins 25, and

any desired sheeting secured over the insulation, giving a building the interior of which presents a finished appearance.

It will be understood that certain features and sub-combinations are of utility and may be employed without reference to other features and sub-combinations. This iscontemplated by and is within the scope of our claims. It is further obvious that various changes may be made in details within the scope of our claims without departing from the spirit of our invention. It is, therefore, to be understood that our invention is not to be limited to the specific details shown and described.

Having thus described our invention, we claim:
