GARDNER PO BOX 443 MUDGEERABA QLD 4213 Invention title: IMPROVEMENTS TO BUILDING CONSTRUCTIONS The following statement is a full description of this invention, including the best method of performing it know to me:- This invention relates to improvements to building constructions and in particular to building constructions for agricultural purposes such as a plant nursery building or greenhouse.

Many different forms of building constructions are available for plant nursery or other applications. In one form of building, disclosed in my application No. 26474/84, a plurality of upright channel sectioned side members are provided and carry at their upper ends longitudinally extending gutter sections to which a roof frame assembly is supported by a plurality of brackets.

Various different roof frame assemblies have been proposed for buildings of the above type and for other plant nursery buildings and generally it is important in such buildings that an efficient means is provided to enable venting of hot air. Such proposals in the past have involved the provision of vent systems at the roof apex and whilst such systems are suitable in many circumstances they do increase the overall cost of buildings.

15 The present invention aims to overcome or alleviate the above disadvantages or at least to provide an alternative to the presently known building S: constructions by providing an improved vent assembly for buildings of the above type. systems for such buildings. Other objects and advantages will become apparent from the following description.

20 The present invention thus provides a vent assembly in a building of the type having a plurality of spaced apart transversely extending arcuate roof frame members and flexible sheet-like roof covering means supported by said roof frame members to define the roof of said building said vent assembly including roller means extending longitudinally of said building and transversely of said roof frame members and supported thereby, said roller means being adapted to be rotated to roll up portion of said roof covering means along said roof frame members from at least one side of said roof frame members towards the apex of said roof to define an opening in said roof for venting air fiom said building.

The building may include longitudinally extending substantially horizontal spaced apart side frame meir bers, the roof frame members extending V FROM JOHN R 5 CiFRDHER POE10 6 ~413 .0 9 90I 0 PHONE HO. +61 7 5 M 1633 run. 04 1996 09:05011 P06 3 between the respective hiorizontal side framne memibers. The horizontal fralic mnembers may be in the forlii of gutters for collctig water froin thc roof of the building, A further substantially horizontal memiber may bc secured to the roof frmre members irt a position spaced fromn a side miember and extending pai-alJe i ereto, the area bet-Avcen the furthier memiber and tlue side mnemlber defining the vent optniuig which is opened or closed by the roller meanis. The roof covering ineanL may include a main roof covering which terminates at thie further mnember and vThich is secured thereto. The roof covering means also may incltudes a secondary coverlng between the furthier inembem' and said fi-lme nember which i' adapted io be rolled up by the roller means.

A cable nia also be provided to extend longitudinally of the building and at a posiimon spaced from the side framie member. A further covering in thie form of At plastics film muay be s5ecured to the Gable and to the adjacent side frame n iiber to define a seal ovcr which the roller means is rolled in moving towards 1. Lfos,.d position.

The further inember suitably is in the form of or defines a gutter for collecting water from the main roof covering, The fuirther member may be a member of Z-sectioiled formn in cross section.

The embodiment of Fig. 2 shows three such building constructions forming a multi-bay building where intermediate wall frames 11' defined by upstanding intermediate frame members 12 are common to adjacent bays, As shown in more clearly in Figs. 3 the side frame members 12 are of channel sectioned form and are supported at their lower end in back to back relationship to further foundation channel members 16 whilst at their upper ends the members 12 cany brackets 17 or 18 which define a seat for the elongated gutter members 13. Each bracket 17 or 18 as shown includes a first flange portion 19 which extends into the channel of the members 12 and is secured thereto by means of bolts passed through aligned apertures in the flange portion 19 and side members 12, The brackets 17 and 18 also include further flange portions extending at right angles to the flange portion 19 with this portion being apertured so as to facilitate connection by bolting to the gutters 13. The further 25 flange portions 20 are provided with a pair of upstanding flange portions 21 which are spaced apart substantially the same as or slightly more than the distance between the side flanges of the gutters 13 so that gutters 13 locate neatly therebetween, the flange portions 21 providing a support for the gutter sections 13 during high wind loading on the roof 15. 1t will be seen that the bracket 18 includes enlarged flange portions 20 and 21 so as to define a mount for a pair of 0.00 0 0*0*

For supporting the roof fiame members 15 a plurality of brackets 22 are provided (see Fig. each bracket 22 being in the form of a short section of pipe flattened and apertured at one end 23 and defining a socket at its other end 24 for neat receipt of the end of an arcuate roof member 15. The flatlened end 23 is disposed at an obtuse angle to the opposite end 24, however, this angle may be varied by simple bending of the end 23 relative to the end 24 to compensate for variations in the ground surface upon which the building is erected, As shown in Fig. 4 the flattened end 23 of the bracket 22 is secured to a flange portion 21 of the bracket 17 or 18 by means of a bolt or other fastening 25 passed through the aligned apnrt:res in the flattened portion 23 and flange portion 21, The gutter 13 is also apertured in this region so that the bolt passes therethrough as shown whereby the bracket 22 is fully supported.

At positions 30 intennediate the upstanding members 12 the channel brackets 31 may be employed being secured to the underside of the gutters 13 and having the roof frame members 15 connected thereto in a similar manner to that shown in Fig. 4. The roof fiame members 15 are thus supported between the opposite side frame members or gutter sections 13 to define the apex of the building intermediate the ends of the roof frame members The roof covering 26 of the building 10 preferably is in the form of a fabric or sheeting which may be a woven fabric, for example a shade cloth or an impervious material such as a plastic film and is disposed above the roof "frame members 25 For this purpose, a Z-sectioned frame member 39 extends longitudinally of the building, parallel to the gutters 13 but spaced therefrom.

One side of the Z-sectioned member 39 is cut-out at spaced positions 40 (see Fig, so as to locate about respective arcuate roof frame members 15. Pieferably a iA' beading member 41 extends along the Z-sectioned member 39 to brace sane in 30 the regions of the cut-out portions 40, the beading member 41 being secured to FROMI JOH-N P G GARD4F- PHO'IE NO. +61 7 5574 16G3. Jun, LJ,4 1996 09:07klr P099 6 the Z-sectioned member 39 in any suitable manner, for example by welding. The region between the gutter member 13 and frame member 39 comprises a vent opening 27, Fabric 42 wound about a roller 43 is secured to the top flange 44 of the Z-section member 39 by any suitable fastener or clamp 45 and it will be apparent that the roller 43 being supported on and extending transversely of the roof frame members 15 may be rolled up or down to open or close the vent opening 27 betwetu the member 39 and gutter 13 by rolling up or unrolling the fabric 42 wound thereon. The main roof fabric or sheeting 26 in this embodiment terminates at, and is secured to the member 39 by an elongated fastener system 46 at the mid flange 47. The member 39 thus acts as a gutter to collect, in the region 48 between the junction of the mid flauge 47 and end flange 49, water run off from the roof fabric 26, A cable 50 is also located in the vent region 27 extending longitudinally of the building and generally parallel to the gutter 13 and member 49, The cable 50 may be either supported on the brackets 22 or roof members 15 and may be tensioned between end roof frame members. A plastic film 51 is secured to the cable 50 and extends between the cable 50 and top flange 28 of the gutter 13 and is secured thereto by a longitudinally extending clamp 52. The film 51 serves as a bottom seal for the vent assembly 38 adjacent the gutter 13.

A shade cloth or other pervious material 53 may also be provided to extend between the gutter 13 where it is secured by the clamp 52 and member 39 where it is secured by the clamp 45 and over the film 51 and roller 43.

When the roller 43 is rolled up, such as to the position of Fig. 4, hot air will be permitted to exit from the building through the vent opening 27 whilst cool air will be allowed to enter being assisted by laminar air flow over the building. When the roller 43 is rolled downwardly, (as shown in dotted outline) it will be positioned over the film 51 so that the roof 15 will be weatherproof "i with water gathering in the fabric 42 of the blind 43 being directed onto the film ~O 51 and into the gutter 13.

i; FROM JOHN R G GARDNER PHONE NO. :+61 7 5574 1633 hui-. 04 1996 09.07A1 7 The vent assembly 38 described ibove may be incorporated inb a part of the building fr-ame and may either cxtend the full length of thie building or only be provided in a sinai] section of thec building.

The frame of the buildig 10 is designed to follow the contour of the land upon which thc building is erected so as to minimise excavation costs, this being accommnodated by the usc of the brackets 22 which may be bent to the requirced angle in accordance with the contour. All the side members 12 in this situation are supported vertically and the gu~tter's follow the fall of the land. It is preferred that the building be reasonably level across its width with a fall down (he length of the buildin~g for good drainage purposes.

The building described above may have many configurations as desired for a suitable puilpose such as for greenhiouses or shade houses.

Whilst the above has been given by wvay of Ilustrative embodiment of the invention, all suich variations and modifications as would be apparent to persons skilled in the art are deemed to fall withiin tli broad scope aud ambit of time invention ns herein defined in the appended claims.
