DE10238371B3 - Cubicle used in the construction of hotels and dwellings comprises a base plate, wall elements, and a ceiling plate - Google Patents

Abstract

Cubicle comprises a base plate (1), wall elements (2), and a ceiling plate (3). The wall elements are dimensioned so that their width corresponds to the edge length of the base plate minus the thickness of the wall element, and their height is selected so that at least three wall elements stood on top of each other form the height of the cubicle. Preferred Features: The wall elements are made of a light-weight material, preferably lightweight concrete or foam mortar.

Description

The invention relates to a room cell according to the preamble of claim 1. This is also an industrial one Prefabricated room cell, which as a compact or elementary Building system is delivered.

These prefabricated room cells are preferred used in new hotel construction and residential construction.

Further areas of use Prefabricated room cells are in the construction of boarding schools, crane houses, nursing homes and the like to see.

Because in these areas mostly recurring Grundrißgestaltungen as well as equipment or equipment of these room cells necessary and required are the benefits an industrial prefabrication by saving construction times directly on the construction site.

The well-known building designs of room cells can be classified into concrete construction, GRP construction and dry construction.

The according to known concrete construction Manufactured room cells have an extremely high level in conventional production Weight on.

To be able to compensate for this disadvantage somewhat Space cells also cast from so-called lightweight concrete to reduce the weight to keep the space cell within limits.

A disadvantage of this type of Space cells, however, is that this Lightweight concrete as an aggregate can be added to significant amounts of sand the required density can be achieved.

When using heavy concrete, which a higher one As is known, the spatial cells are thin-skinned made to keep the weight of the room cell low.

This influence on the weight of the room cell is again important because all means of transport and hoists, which from the manufacture of the room cell to the installation of the Space cell in the building, must be selected according to the weights of the room cells. Furthermore there are significant effects on the design of the statics for the structure, in particular in terms of ceiling and traffic loads.

All manufactured using this well-known concrete construction method However, room cells have the disadvantage that when casting these monolithic room cells while cracks occur during the drying process.

Are these superficial and visible in the walls the room cell these cracks afterwards be closed.

However, this is significant Additional effort connected.

However, these cracks occur inside on the wall, they can no longer be closed and thus reduce the static stability the room cell.

A disadvantage of the room cells, which are made of GRP, is the high effort in manufacturing and a complicated processing in the design and equipment the room cell.

The different ones are particularly unfavorable thermal expansion coefficient between GRP and other building materials, such as tiles.

Here is an inevitable later crack formation go out.

In addition, the requirements to noise and fire protection according to DIN only with considerable and cost-intensive additional measures to fulfill.

The well-known room cells, which are created in the dry construction principle have the disadvantage on that to warranty the static load-bearing capacity reinforced stand structures made of U- and Rectangular profiles are required.

However, these are due to the high manual effort costly.

The invention is based, which Weight problems in transport and assembly of the known To reduce space cells and a high static load capacity to reach.

This task is performed by a room cell according to the main claim 1 and in a further embodiment according to subclaims 2 to 6 solved.

The invention is based on the 1 and 2 are explained in more detail, whereby 1 a side view and 2 the top view of the room cell according to the invention shows on a prefabricated base plate 1 become wall elements 2 placed transversely on which a ceiling plate 3 is put on.

These wall elements 2 are preferably dimensioned so that their width corresponds to the edge length of the base plate minus the thickness of the wall element.

The height of the wall element 2 is preferably chosen so that at least 3 wall elements standing on each other 2 the height of the room cell.

The wall elements 2 The room cell according to the invention are preferably prefabricated from lightweight concrete, preferably aerated concrete, in accordance with the dimensions of the room cell.

As the material of the wall elements 2 the room cell are also many other lightweight materials, such as expanded concrete or with concrete as a binder in plat pre-burned clay balls conceivable.

In a test variant created a room cell, the wall elements of which have a bulk density class of 0.6. The calculated value of the thermal conductivity was 0.16 W in this embodiment.

The wall elements designed in this way 2 the space cell according to the invention are preferably installed in the composite, as in 1 becomes clear.

The connection of the wall element 2 with each other takes place by means of the materials selected for the respective lightweight material in known mortar or adhesive technology.

The room cell according to the invention designed in this way Fulfills all structural requirements with regard to thermal insulation, fire protection and the like. As well as all static requirements.

In a special embodiment of the solution according to the invention, a stabilizer grid can be used to transport the space cell according to the invention 4 to be ordered.

This stabilizer grille 4 preferably consists of two stabilizers 5 , one each under the base plate 1 and the other over the ceiling tile 3 the room cell is arranged so that the legs as stabilizers formed in parallel 5 are connected to a main web running in the middle of the cell.

The length of the legs of the stabilizers 5 depends on the sizes of the base or ceiling slab 1 and 3 chosen so that the leg ends of the stabilizer 5 over the two plates 1 and 3 protrude.

The vertically opposite leg ends of the stabilizers 5 are preferably by means of clamping elements 6 releasably connected like tension screws.

In a further embodiment, the under the bottom plate 1 arranged stabilizer 5 replaced by that in the bottom plate 1 fasteners 7 incorporated, preferably welded to the bottom profile, which are the lower receptacle of the clamping elements 6 serve.

These tensioning elements 6 as well as the entire stabilizer grid 4 can be removed after inserting the room cell into the building structure, but it is also possible to leave these clamping elements on the room cell.
