Description

1 TITLE: Portals
DESCRIPTION
2335212 This invention concerns portals.
Portals are generally a form of entrance to a building. It is desirable for portals for public buildings to be light and airy. Therefore, portals are often provided with glazed roofs. It is also desirable for portals to be of strong construction whilst allowing as much glazed area as possible.
An object of this invention is to provide a portal construction.
According to this invention there is provided a portal construction comprising a framework having a glazed roof mounted thereon.
The fi-amework preferably comprises vertical support posts, rafters each connected to a support post and to a ridge, and eaves beams connecting the support posts.
The rafters are preferably of rectangular hollow section. Preferably the rafters have internal formations for location of connectors used to join rafters. Main rafters are preferably shaped to receive glazing beams of a conventional conservatory roof system, such as channels formed in top sides of the rafters.
At ridge ends connectors are preferably provided whereby the angle of the rafters connected thereto is radially adjustable. The preferred connector for a ridge end comprises a pair of spaced parallel plates having aligned holes to take a bolt through a pivotable 2 member. The parallel plates are preferably provided by channel section extrusion cut and machined appropriately. The pivotable member preferably has a tenon or the like for locating in the end of a rafter.
To form an apex for a portal of the invention, preferably a rafter component is provided having a central, preferably flat top, section and angled wing sections on opposite ends of the central section. Rafter sections may then be connected to either end using rafter to rafter connectors as mentioned above.
The ridge end connectors may, therefore, be fixed to one side of the central section of the rafter component. The ridge end connector is ideally, therefore, of C-section. Other C-section connectors may be used to connect ridge members to one or both sides of the or other apex forming rafter components.
The eaves beams are preferably of L-section having attachment means on one side for internal cladding, if desired, and on the opposite side for attachment of guttering or brackets for supporting guttering.
It may be convenient to use cleats shaped to mate with support posts and fixed thereto to attach the eaves beam to the support posts. The support posts are preferably of the same section as the rafters to which they are connected.
The glazed roof used on portals of the invention preferably comprises a ridge beam and glazing bars extending therefrom. The ridge beam preferably sits on the ridge members of the portal fi-amework and the glazing bars on the rafters. The glazing bars are preferably of the type described in our GB Patent No. 2275958 or our GB Patent Application No. 9705044.7.
3 The ridge beam may be of the type described in our co-pending Patent Application No. GB 2310870A.
This invention will now be further described, by way of example only, with reference to the accompanying drawings, in which:
Figure 1 shows a typical fi-amework for a portal; Figure 2 shows a ridge end of the portal of Figure 1 with glazing bars fitted; Figure 3 shows the ridge end of Figure 2 from the other side without glazing bars fitted, Figure 1; Figure 1; Figure 4 shows part of the eaves of the portal of Figure 1; Figure 5 shows a rafter to vertical support connection from outside the portal of Figure 6 shows a rafter to vertical support connection from inside the portal of Figure 7 is a section through a main rafter of the portal of Figure 1; Figure 8 is a section through a hip rafter of the portal of Figure 1; Figure 9 is a section through an eaves beam of the portal of Figure 1; Figure 10 shows a hip rafter connector of the portal of Figure 1; Figure 11 shows a rafter connector as used in the portal of Figure 1; and Figure 12 is an end view of a connection cleat used in the portal of Figure 1. Referring to the accompanying drawings a portal comprises a fi-amework 10 of the type shown in Figure 1 carrying a glazed roof The framework 10 as shown is for illustrative purposes and portals can be constructed having any of the typical features illustrated. The f=ework shown has two different hipped end shapes 12, 14, one being 4 rectangular and the other being a bell end. An entrance porch fi- amework 16 is provided set forwards from the main fi-amework.
The fi-amework 10 comprises vertical support posts 18 connected to main rafters 20 in turn connected to ridge beams 22. At each end of the portal framework hip rafters 24 are connected between the ends of the ridge and the support posts 18. Around the perimeter of the framework connected to the tops of the support posts 18 are caves beams 26. The main rafters 20 are actually connected to special rafter components 28 to which the ridge beams are connected and at each end of the ridge the hip rafters. The rafter components 28 comprise a central section 30 with short angled rafter sections 32 at each end.
The main rafters 20 are generally of hollow rectangular section having a top 33, bottom 34 and sides 35. The top 33 has a channel 36 formed therein to receive glazing bars as will be described later. Sides 35 of the rafters 20 have outer decorative shaping. On the internal surfaces of the top 33 and bottom 34 are pairs of ribs 38 which are to aid location of connectors 40 (see Figure 11) forjoining rafters the special rafter components 28.
The connectors 40 comprise a pair of walls 110 connected by webs 112 spaced inwardly from ends of the walls. The walls have inwards returns 112 at their ends that form gaps in which the ribs 38 of the rafters 20 can locate.
The hip rafters 24 are also hollow rectangular sections and have a top 42, a bottom 44 and side walls 46. The top 42 has a central channel 48 for receiving packing material for supporting so-called Georgian glazing bars which have their undersides indented. The side walls 46 have decorative formations on their outer surfaces. Internally of the hip rafters 24, the top and bottom each have a pair of longitudinal ribs 50 to aid location of ridge end connectors 52 (see Figure 10).
The support posts 18 are of the same shape as the rafter to which they are connected.
The eaves beams 26 (see Figure 9) are generally L-shaped having an intended vertical wall 54 and an intended horizontal wall 56. On the intended inner surface of wall 54 are fir-tree section ribs 58, 60 to which internal PVCu cladding can be attached. On its opposite face are a pair of spaced hook formations 62, 64, which provide locations for attachment of brackets 66 for guttering 68 (see Figure 6). At the top of wall 54 is a longitudinally slotted enlargement, which can receive slidingly heads of bolts used to secure the glazing bars to the caves beam. The caves beams 26 are connected to the support posts 20, 18 via connector cleats 70 of the type shown in Figure 12. The cleats 70 have a central part 72 and wings 74 either parallel therewith or at a chosen angle thereto as necessary. Positioning of the cleats 70 is shown, for example, in Figure 4.
Ridge beams 22 are connected to main rafters 20 by means of C:-section connectors 80 that are bolted to the rafters and into which ends of the ridge beams are bolted. At ridge ends where a hipped roof end is to be provided a differently shaped C-section connector 82 is used. The connectors 82 have spaced semi-circular plates 84 with corresponding through holes 85 to receive bolts 86 through ridge end connectors 52 (see Figure 10). The connectors 52 have extending therefrorn a pair of tenons 86 that slot into the ends of the hip rafters. Screws or bolts through sides of the rafters into the tenons fix the rafters in place.
Both the connectors 80 and 82 may be made from the same extruded aluminium section. The connectors 80 are simply cut to size from a length of aluminium extrusion, whereas the connectors 82 require fixther machining of a cut length of the extrusion., 6 To fix glazing to the roof of the portal glazing bars 89 are fixed on top of the rafters. The glazing bars are of the type described in our co- pending patent application number GB 9705044.7 which comprise generally an inverted T-section bar 90 having a top capping 92 and a bottom capping 94 mounted thereon. The cappings 92 and 94 have co-extruded gasket material on their edges. The bottom capping has its gaskets trapped between glazing material 96, such as polycarbonate sheeting, and the bar 90, whereas the gasket material of the top capping is pressed onto the glazing material, The top capping has depending internal formations that are captured in a slot of the glazing bar.
The glazing bars 90 are connected to a ridge member 100 of the type described in our co-pending patent application number GB 2310870A mounted on top of the ridge beams 22.
Walls of the portal may be formed as desired. Typically bottom parts may be filled in and upper parts may be in the form of windows.
