This invention relates to rooms for ships, constructed of metal and capable of being taken to pieces, in which the walls, ceiling and floor consist of standardized constructional elements 5 which can be assembled where required without special tools. The constructional elements consist of two or morespaced metal plates. The main feature resides in the construction of the abutting edges or the connection of the individual 10 elements together. The connection must be effected without the use of additional means, such as riveting, welding and the like, and yet must be absolutely secure. It is also necessary to take care that there should be a possibility of 5 providing insulation between the individual elements. Finally the possibility of a tolerance or compensation is required in order to be able to make the rooms of any desired shape, it being remembered that smooth walls are required. These requirements which are applied to the connection between the constructional elements also apply to the connection between the elements and the ceiling and floor. It is desirable that the various abutting edges of the elements 25 should all be of similar construction.

Metal constructional elements are known in which the abutting edges are similarly shaped on all sides. In some cases the abutting edges are flat and are embraced by holding means; and in other cases the constructional elements have similarly shaped tongues and grooves, which either interengage directly or are held by suitably shaped intermediate pieces. In all these cases the points of connection leave projections 35 and thus do not fulfil the requirement of providing smooth wall surfaces. Also the connecting means, for example the post-like intermediate pieces, are not suflicient for making it possible to assemble the constructional elements in such a 40 manner as to completely close the space. Recognizing this fact it has been proposed to provide constructional elements with step-like abutting edges, but a connection made therewith does not meet the simplest requirements of a reliable assembly of the elements because a lateral bending along the abutting edges was possible.

The invention fulfils the general requirements for constructional elements for building up rooms for ships, which can be taken apart and in addition further considerable advantages are obtained, which in the first place meet the extensive endeavours at standardization in fitting out ships. At the same time there is a reduction in the original cost of the constructional elements 55 and in the cost of assembly.

' According to the invention use is made, for connecting the constructional elements together, of post-like intermediate pieces, which either embrace or are embraced by the constructional plates, without forming external projections. The connection of the elements with the ceiling and the floor is efiected by means of head and foot intermediate pieces which have the same holding section as the post-like intermediate pieces. The ceiling intermediate pieces are made in two parts in the longitudinal direction, the two parts extending along the wall embracing the upper edge of the elements being adjustable. Further, the foot connecting piece is made roofshaped at the lower edge and is supported on wedge-shaped strips extending along the wall on both sides which can be drawn together by tension screws, and thus cause the elements to be clamped between the ceiling and floor. The possibility of adjusting the ceiling and floor strip connection has the further advantage that any loosening of the elements due to distortion of the ship can be met by re-adjustment. It is naturally possible instead of the two-part ceiling and floor strips to use strips in one piece, but in order to facilitate a completely closed assembly of the elements it ,is advisable to have either the ceiling or the floor strip made in two parts and adjustable.

The use according to the invention of post-like intermediate pieces and of ceiling and floor strips provided with the same holding section makes it possible to construct the elements with all the abutting edges of the same shape, which involves considerable saving in the manufacture. It is possible either to secure between the metal plates of the elements simple round, oval or polygonal grooves or similarly shaped tongues at the abutting edges by spot welding or the connecting partsmay be made directly from the metal plates. The abutting parts of the elements may simultaneously serve as distance pieces for the metal plates. The desire for standardization is met by the elements according to the invention in a manner which can scarcely be made more simple.

It is of great importance that the post-like intermediate pieces can be made directly from insulating material so that the elements can be completely insulated from one another. The surrounding of the post-like intermediate pieces by the constructional elements causes a reduction of the static requirements thereof so that they can be made of insulating material of high quality but cheap and light.

Various constructional examples of the invention are illustrated in the accompanying drawing. Figures 1-8 show cross-sections through the connection points of two constructional elements,

10 connecting piece in a. round form, Figure 3 shows it in rectangular shape and Figure 4 in square shape. Figure 5 illustrates a construction in which the abutting parts e extend outwardly like tongues, While the connecting part (1 has correspondingly shaped groove-like engagement places. In Figures 6, 7, and 8 three different constructions of the connecting parts I, g, h are shown which serve for obtaining angular or curved walls. Naturally the connecting pieces c, d, f, g, it can be hollow or solid, as required.

In Figures 9 and 10 end connections of the elements to the ceilings, floors and supports are illustrated. In the constructional form with groovelike abutting parts b according to Figure 9, on

the one hand a rigidly connected cover strip 1' and on the otherhand a round connecting piece 0 is provided. The counter member In serving for receiving the latter is constructed in two parts with the object of obtaining complete closure.

Figure 10 shows a form in which the two-part closure members I and m are adjustable by means of screws n, while the upper cover strip 1 directly embraces the tongue-like abutting part e of the constructional element, the lower countermemher m has oblique surfaces 0 in roof-shaped arrangements, on which rests the connecting piece p provided with similar surfaces. It is therefore possible when loosening occurs to readjust the connection, whereby the two parts of the countermember m slide like wedges below the connecting piece p and press the latter upwards.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:- 1

1. In rooms for ships, constructional elements comprising separated parallel plates forming a double wall, curved parts entirely embraced between the planes of said parallel plates and rigidly connected thereto adjacent the edges of said parallel plates, means for holding said constructional elements in place relative to each other comprising posts, the longitudinal sides of which are curved to fit the said curved parts whereby a smooth surface is formed of connected constructional elements, and two parallel strips adjusted between the said curved parts and the ceiling of the room, said strips having each a curved surface to fit against a portion of the curved surface of said curved parts, adjustable means connecting said strips whereby the strips are made to grasp tightly said curved parts.

2.
