Claims. 1

This invention relates to a metal wall construction and is for an insulated metal wall for structures such as ship hulls, deck house of a boat, and the like.

While the invention is especially applicable to hulls and deck houses for boats, and will be specifically described in that connection, it is to be understood that the term deck house is used in a broad sense to include similar structures. Metal housing of this kind is formed with vertical stiffeners or reinforcements to which is secured a metal sheathing. This sheathing is entirely weatherproof, but affords no insulation against external temperatures, and the present invention provides a neat, economical and efficlent insulated wall structure.

According to my invention, the insulation is confined between the steel sheathing and plywood or like panels. The panels in turn are held immovably in place by strips or battens which are bolted to the webs of the upright metal studs or supports, the entire insulated structure being prol, overlying these margins,

vided without any other metallic fastenings be-- 7 tween the insulation and the metal wall.

The invention may be more fully understood by reference to the accompanying drawings, in which:

Fig. l is a sectional plan view through a portion of a ship having a hull or deck house wall embodying the present invention;

Fig. 2 is a detail horizontal section through a portion of the wall where a doorway is formed;

Fig. 3 is a horizontal section on a larger scale than Fig. 1 showing several panels of the wall;

Fig. 4 is a fragmentary horizontal section on a larger scale than Fig. 3, showing a part of the wall adjacent one of the supporting structures as constructed throughout certain parts when framing flange is not insulated; and

Fig. 5 is a similar view for'parts requiring insulation of framing flanges as generally is desirable for the living quarters of a boat.

Referring first to Figs. 1 and 3, the deck house wall is comprised to a metal sheathing formed of light gauge metal plate, this metal sheathing being designated 2. At intervals along the wall are upright structural metal sections preferably of a T section, these having a web portion 3 and a flange portion 4. The metal sheathing is welded to the vertical edge of these T sections as more plainly shown at 5 in Figs. 4 and 5.

According to the present invention, battens or layers of soft insulating material designated 6 are laid against the sheathing on the inner face of the wall, the insulation being of appropriate:

thickness. It may be any suitable insulating material, preferably a. fireproof material such as mineral wool which may be prepared into battens of uniform thickness. The insulation extends across the full width of the space from one upright structural member to the next. Laid against the inner face of the insulation are panels l which are preferably formed of insulating material or plywood, but which may be formed of any appropriate fiber or composition material, or which may even be metal. The panels I are of a width such that they may be inserted into the space between two structural sections. the edges of the panels 1 preferably being spaced a slight distance from the webs 3 of the structural stiffeners.

Secured to the webs 3 of the metal sections by means of transversely extending bolts or rivets B are timbers or battens 9 which fit under the flanges 4 of the structural sections and which bear against the vertical margins of the panels The strips or timbers 9 are of a dimension such as to press the panels inwardly against the resistance of the insulation material, thereby squeezing the insulation material between the sheathin 2 and the panels I to firmly hold the insulation material in place. At the same time the outward pressure of the insulation pressing the panels against the wooden strips or battens 9 firmly holds the panels 1 in place.

Thus it will be seen that an insulated wall of neat appearance is very economically provided without any need for any extra welding. The structural sections 3 may be pre-fabricated with holes at appropriate locations to receive the through pins or bolts 8. The wooden strips or battens 9 can be pre-cut to length before being taken aboard the ship, and the panels I may be fabricated or out before they are brought aboard, to the necessary size. The only operations that need be performed after the deck house is erected, to complete the insulation of the walls, is laying the insulation in place, and the application of the panels 1, and the securing of the strips 9 to the structural sections. This can be done rapidly by unskilled labor, and does not even require the services of a carpenter.

In the ship's ofiices, or living quarters, it may be desirable to provide more complete insulation, and at the same time conceal and provide a padding over the flanges 4 of the metal sections. This may be easily accomplished as shown in Fig. 5 by also laying a pre-formed strip of insulating material in on the outer face of the flange 3 4 of the metal sections over which is laid a strip of canvas or other fabric I I. The strip of canvas is made wide enough so that the sides of the strip may be folded under the flanges 4 and brought in against the webs 3 of the sections. The wooden strips 9, as they are clamped into place, stretch this canvasror fabric tight, andclamp the edges of the fabric. to the two fiaces. of. theweb, 3. In Fig. 5 these edges of the strip of canvas are designated [2, This provides effective insue lation and padding over the flanges of the sections with very nominal additional. expenseandlabor.

Fig. 1 illustrates a portion" of.- a ship structurein which there is a transverse; bulkhead. lfifand? longitudinally-extending bulkheads I4, with a doorway at 15 establishing communicationbee tween the area on one side of the transverse bulkhead and the other. The portion of the deck: house forwardly of the bulkhead I3 may be living quarters, in which the metal sections are: completely insulated, as shown in-Fig. 5, whereas the portions of the wall-rearwardly ofthe. bulkhead l3 may be constructed without the insulation over the flanges, this part of the. wall being constructed as shown in Fig. 4. It. willbe seen. that whether the flanges are. insulated or not, the basic construction is the. same, and-the-fact that in some portionsof the wall the flangesof. the: sections are to be covered, whereas in-others theyare not, does not require any difierencein the general construction-or. assembly.

In Fig. 2 there is shown aconstruction. which; is used where there is a doorthrough the deck. house. In this instance the upright. structural section which is similar to all of the other.struc.- tural sections, andwhich in Fig. 2 is designated [6, is welded to the metal sheathing a slig l'1t.-distance back from the opening in the. sheathingwhere the doorway is located, so. that there-is a2 projecting ledge of sheathing ll in Fig. 2- beyond.- the section iii. The insulatedwallis constructed? aspreviously described up tothe sectionl-B, and. a wooden strip or batten 9 is secured, in. place. on. one side of the web of the structuralmemberl6.v Fitted under. the flange. of. thestmcturalmember l6 and confined by the overhang ll of the sheathing is anotherv wooden strip- 18.. This strip I8 is. especially. desirable where the structuralmember- I6 is to be covered with insulation asfdescribedinconnection with Fig. 5. The actual door frameis indicated in dottedlines and. ismar-ke'd. I9. It forms no part of the present invention, however- From, the foregoing. itv will be seen that the present invention provides aneat, economical, and easily installed-wallv construction, whichcan be rapidly installed and which. provides effective and efficient insulation without undue increase of cost or labor. Not only is the insulation desir able from the standpoint. ofoomfort, but also from the standpoint of deadening. noise. andv sound. The inventionmoreover provides, a layer of soft insulation and then, by reason; of. the. insulating qualities of. the plywood or other: panels, a layer of hard insulation, the first layer being against the steel constitutin the. outer.- wall of. the deck. house, and the. second formingthe inside finish of the deck house or other structure/the wooden strips or timbers 9" also improving the appearance, as thesetimbers and thepanels may be appropriately finished.
