Prefabricated Building for Storage or the like


The present invention relates to a demountable prefabricated building incorporating novel roof support modules which also serve to support storage racks or shelves in the building.


It is well known that on all manufacturing sites a portion of the site must be used as a storage area for the raw materials or components used in the manufacturing process. The allocation of a large portion of the site for storage limits the area which can actually be used for the manufacturing process and all manufacturers seek to restrict the space used for the storage of raw materials and components to a minimum.. Generally the storage area takes the form of a warehouse in which the materials are protected from damage by extreme weather conditions although in some manufacturing industries the raw
materials can be left in the open. Where it is
essential to keep the stored materials under cover
the warehouse represents a fixed part of the manufacturing site which can only be used for storage. If a manufacturer should wish to expand the production
area into the storage area it is necessary to remove
a portion of the existing warehouse. This is of
course an extremely expensive procedure.
A typical conventional storage, building is
shown in the U.K. Patent Specification No.1406449 and comprises several solid partitions made up of frameworks of horizontal and vertical rods supporting storage
racks or shelves. However, the partitions include
concrete walls and the upper, ends of the vertical
rods are embedded in a concrete roof so that it is not feasible for the building to be dismantled and moved
to a different location.
U.K. Patent Speci ication No.1173520 shows
how a field stores dump can be constructed from
cubic stores containers which can be stacked or
linked together by means of mating metal loops.
While such units are quite versatile for example for
military use, they would be of limited use for
industrial purposes.

The present invention provides a demountable prefabricated building comprising at least two
support modules supporting a roof extending between
5 them, characterized in that each said support module (12) comprises a plurality of uprights (13) connected to one another by horizontal struts (14) in a three
dimensional structure, the upper ends of the uprights being provided with flanges (20) to which are releasably

10 secured supporting elements (25,27) for the roof (11)
and at least some of said horizontal struts (18) also
serving to support storage racks (34) or shelves.
The building can be made up of any number of modules preferably arranged in rectangular formation.

15. The modules are themselves preferably rectangular
in plan view, and those supporting outer edges of the
roof can be provided with cladding on their outer
sides to form walls for the building.

Figure 1 is a perspective view of a building for storing materials ,
Figure 2 is a perspective view of a primary
roof support module ,
25 Figure 3 is a perspective view of a roof support link module, Figure 4 is a sectional elevation showing a roof supported on roof support modules,
Figure 5 is a portion of an alternative roof, support module, and
Figures 6 and 7 are elevations, each showing a portion of a roof and the associated roof support module.

Figure 1 shows a warehouse for storing materials comprising a roof 11 supported on rows 12 formed of alternate primary and link roof support modules.
Each primary roof support module, as shown in Figure 2, consists of six vertical columns 13
interconnected- by horizontal steel angle girders 14. The module is reinforced by diagonal steel angle girders 15, 16, extending between the columns 13 on one side of the module and between the columns 13 at each end of the module. The top of each coluinn 13 is provided with a rafter connection 20 by which the module is connected to rafters in the roof 11.
Each roof support link module, as shown in
Figure 3, comprises two vertical columns 19 each provided at their top with a rafter connection 20.
The vertical columns 19 are interconnected by a
series of steel angle girders 21 and horizontal girders 22 extends from either side of the vertical
columns 19 for connection at their ends to a primary
roof support module. The connection of the link
module to the primary module is achieved by means
of a series of cleats 28 which connect to the horizontal
angle girders 21 on the link module.
As can be seen from Figures 1 and 4 the roof
11 of the warehouse has a central ridge 23 with ridge
rafters 24 on either side. Support units 25,27
of suitable size and shape rest on the horizontal
flanges 20 and are bolted to them. These units in
turn support the rafters 24. The connection of the
ridge rafters 24 to a rafter connection 20 of a roof
support module is shown in Figure 6.
In the construction of large warehouses it is
necessary to arrange two rows of roof support modules
back to back between the outer wall of the warehouse '
and the central ridge. In this case, as shown in
Figure 7, valley rafters 31 which connect to form
a valley gutter 32 are used, the valley gutter 32
being connected to the rafter connections 20 of the
roof support modules . The roofing rafters are covered
with a suitable form of cladding, for example
Perspex Nylon (Registered Trade Mark) sheet. As
can be seen in Figure 1 the rows 12 of roof support
modules may be used to form the outer walls of the

~ warehouse and in this case they are also covered with a suitable cladding 32 such as asbestos sheet or glass fibre-reinforced plastics corrugated sheet. In addition the roof support modules at each end of the warehouse are provided with hinges for carrying doors for closing the warehouse.
The rows of roof support modules provide racks which can be used for the storage of materials in the warehouse. In a preferred embodiment, illustrated in Figure 5, a plurality of tubes 34 may be welded between the horizontal steel angle girders 18 to provide storage shelves particularly suitable for storing drums. Alternatively steel, mesh or
chipboard shelves may be carried by the angle girders 18.
As shown in Figure 6 a spray line 26 may be provided along the central ridge 23 of the roof for sprinkling water onto material stored in the warehouse in the event of fire.
It will be appreciated that the combination of rack and link modules designed for supporting the roof rafters make it possible to quickly erect a storage building of any design, shape or size.
Substantial cost savings are achieved and it has been found, in some instances, that a storage warehouse constructed of the rack and link modules according to the present invention can be erected for approximately one third of the cost of erecting a warehouse of the same size using conventional
building methods.
The modules are particularly suitable for
erecting a building on an existing concrete area, for example a dock and goods receiving compound, because there is no need to prepare the ground before
installing the modules. However where a previously unused area is to be used as. a site for the storage building it is normally desirable to reduce the
ground level to provide a foundation for the building. The ground level is reduced to take a hard core layer of 15-20 cm which is consolidated with strips of
reinforced concrete 10-15 cm thick laid lengthwise to correspond with the rows of roof support modules .
The roof support modules can be built in standard units on jigs and generally are about 3 metres long, one metre wide and 3.5 metres high. In the errection of a building they are set in single rows at the sides and back to back below the valley rafters and central ridge. The primary roof support modules are
approximately 2.5 metres apart and the link modules introduced between the primary modules. All the
modules are bolted to the floor and to each other as necessary.
The roof is formed by connecting the standard roof rafters to the rafter connections on the modules , four connections being made for each five metres of roof span with a maximum distance between the rafter connections of three metres. Sheeting angles, jig made, are fitted to the rafters to mount the roof cladding. Cladding for covering the side walls is bolted direct to the lateral angles at the rear of the modules .
It is envisaged that some of the horizontal angle girders could be movable so that the racks can be located at different positions on the modules.
The building shown in Fig.l is a free standing building. However, it will be appreciated that a building according to the invention could also be - used to extend existing buildings,for example in the form of a "lean to".
