UNITED STAJT'E'SD- PATENT ounce SYLVESTEB B. OREAMER AND HARRY R. ANSEL, OI COLUMBUS, OHIO, ASSIGNORS TO THE INTERNATIONAL DERRICK & EQUIPMENT COMPANY, 01' COLUMBUS, OHIOfA congona'rron or 01110 BUILDING STRUCTURE Application filed May 21, 1928. 7 Serial No.. 279,837.

Our invention relates to building structures. It has to do, more particularly, with building structures which are made of sheet metal.

Buildings of this type are put to a wide variety of uses. It is frequently-desirable to insulate these buildings for various reasons. For instance, they are sometimes usedas workshops or for storage of materials that may be injured by temperatures which are too low or that may be injured by condensation moisture gathering upon the interior of the walls of the building. It is also sometimes necessary to insulate a building of this type in such a manner as to protect the interior of the building from excessive heat, due to the rays of the sun striking the buildingor due to other causes.

Heretofore, some attempt has been made to insulate metal buildings both of the standard type and the non-standard type. The most common method of accomplishing this hasbeen to erect buildings in the usual manner, then apply wooden strips upon the interior to the structural frame to which the metal sheets are attached and, finally, to attachthe insulating material to these wooden strips. The application of these wooden strips is laborious because it is usually necessary to notch the strips to fit around the various steel members. This structure results in an air space between the plaster-board or other insulating material and the sheeting which is usually of such width that it is possible for air currents to become started and thus cause more or less ventilation which tends to reduce the insulating properties of the entrained air.

This practice of applying the insulation after the building is erected has, in the past, required removal of the insulation before the building could be dismantled. Furthermore, it has also required destruction of much of the insulating material or such injury thereto as to prevent its subsequent use.

One of the objects of our invention is to provide a means for insulating a metal building and a means for applying the insulation to a standard metal building in such manner that the efiectiveness of such insulation will be increased. Another object of our invention is to provide a method of applying insulation to a standard metal building without increasing the erection cost of the building. Still another object of our invention is to provide a means for insulating a metal building which is of such form and so applied that the building may be disassembled, transported to a new location, if desired, and then reassembled without either injuring or removing the insulation.

In obtaining these and other objects, we have conceived the idea of providing a panel for standard sectional buildings which embodies both a sheeting unit and insulating means. The structure of our device is such that it may be constructed-as an entity in the shop and transported and installed in a manner similar to the installation of panels which are now being marketed without insulation.

Our invention preferably takes the form of a panel structure to which is applied a sheet or sheets of metal lined with commercial insulating material in sheet form. The

insulating material is preferably placed in between the structural framework and the metal sheeting of our panel and in intimate contact with this metal sheeting. It is held in place by the metal clamps and rivets or bolts which holdthe metal sheeting and the cap strip in assembled position uponthe skeleton framework of the panel.

The preferred embodiment of our inven tion is shown in the accompanying drawings wherein similar characters of reference designate corresponding parts and wherein:

Figure 1 is a perspective view of a panel section embodying our invention. I

Figure 2 is a detail in perspective showing the manner of utilizing. one of the cap strip clamping means for clamping the insulating material to the metal sheeting.

Figure 3 is a section taken on line 33 of Figure 1. p

Figure 4 is a sectional view similar to Figure 3 but showing our invention as embody.- ing corrugated sheeting.

Figure 5 is a sectional view showing a mod ified form of the means for attaching the insulating material to the sheeting. 1

Referring to the drawings, we have shown a structural panel comprising top andbottom horizontal girts 1, vertical side columns 2 and an intermediate girt 3. These girts and columns preferablytake the form of angle irons and are so connected together as to form a skeleton framework of rectangular form.-

' thereon is the metal sheet which is preferably comprised of a plurality of panels 5 joined by cap strips 6 and interlocking clamps 7. 8 and 9 extending entirely through the insulating material.

The clamps 7 are of the type preferably used for attaching the metal sheets and cap strips to the intermediate girts 3. This clam is provided with a T-shaped head, like the clamp shown in Figure 3, and with a. bifur cat-ed shank designed to embrace the out.- standing flange of the angle iron constituting the intermediate girt. Inasmuch as it is usually desirable to cut an opening in the insulating material for the passage of this clamp 7 through it, we preferably plug this opening with a. pieceof insulating material,

as at 10.

The clamps 8 are what is known as J-clamps and are provided with a T-head, as shown in Figure 3. and with a shank that is bent laterally after passing throughthe insulating material so as to embrace the girts 1 and hold the cap strip firmly .in position. \Ve preferably provide-plugs 11 of insulating material for fitting in the openings which have been cutv through the insulating material for the passage of the shanks of the clamps 8.

The clamps 9 are similar in construction to the clamps 8. However, they are preferably supplemented by bearing strips 12 which are interposed between the bent over portions of the shanks of the clamps and the insulat iug material. The openings through which these clamp shanks pass are, likewise, closed by plugs of insulating material 13.

The metal sheeting and the insulating material are additionally secured to the skeleton framework by bolts and nuts or rivets which pass through the girts 1 and 3, and the columns 2.

In Figure 4 of the drawings, we have shown.

15 are shown as being assembled with the insulating material 16. The sheeting and insulating material are held in assembled relation by means of rivets 17 and a metal strip 17 It will be understood that any type of sheeting and any form of fastening means may be employed. I

A modified form of means for attaching the insulating material to the sheeting is shown in Figure 5. In this figure a T-head bolt 18 is applied to the sheeting and cap strip to serve the same pur ose as the clamps 9. A nut 19 serves to 1101 the cap strip and the metal sheets in assembled relation. The shank of the bolt 18 extends through a hole in the insulating material and a washer or strip 20, preferably of metal, and nut 21 serve to hold the insulating material to the sheeting. It will be seen that we have provided a unitary structure in the form of an insulated panel. This insulated panel may be incorporated in a building structure or removed therefrom as an entity. It may be completely fabricated in the shop at the time of assembly which is, of course, the time most favorable for doing this work in the cheapest and most economical manner. Practically no field work is necessary over and above that which is usually required in assembling panels for non-insulated standard buildings.

and WOl'kIlltll'l-llkG appearance and when it is found desirable to move the building, the panels'can be unbolted and moved without injury to the insulating material. In other words, the entire building can be salvaged and used over and over again. Buildings constructed of our insulated panels may be readi- 'ly heated in an economical and efficient manner during the colder months. During the hotter months, the interiorof the building is protected "against undue heat due to the rays of'the sun. Likewise, the gathering of condensation moisture on the metal sheets, due to the difference between the temperatures on the outside and inside of the building, is pre eluded. In fact, our invention provides an economical means of. overcoming practically all the objections which are ordinarily raised to the standard steel building for. use of fac- Furthermore, the structure presents a neat tory buildings, warehouses and transformer houses and other types of electrical equipment where condensation, or moisture is an objectionable feature.

Having thus described our invention, what we claim is:

1. Building structure comprising a skeleton framework constructed of angle irons, a metal-sheeting unit; constructed of a plurality of panels of metal sheeting and cap strips, a sheet of insulating material interposed between said metal sheeting unit and said framework, and means passing through said sheet of insulating material for securing said framework, said metal sheeting unit and said sheet of insulating material being secured together to form a panel.

2. A building structure comprising a skeleton metal frame, a metal sheeting unit mounted thereon and constructed of a plurality of panels of metal sheeting and means for securing said metal sheeting in position, a sheet of msulatmg material carried with said. frame work, and means connecting these parts together to form a panel.

In testimony whereof we herebynflix our signatures. 1
