摘要:
A greenhouse includes a frame structure (1), an outer transparent covering layer (2), and a transparent inner layer (7). A transparent insulating sheet-like material is located between the inner and outer layers in close proximity to the inner layer (8). The insulating sheet-like material has a cellular structure (4, 5) with the axis of its cells generally oriented normal to the plane thereof material so as to transmit incident light therethrough. The insulation material helps to retain heat within the structure while avoiding detrimental effects, such as loss of light transmissivity. The creation of an air gap on one side between the transparent insulation and one of the glazings allows for control of moisture and snow buildup.

A lightweight building construction system comprising multiple similar stressed roof and wall paneling modules (22, 122) assembled together to form a modular building envelope. Each roof module (22, 122) typically includes a double-skin panel (1,4/101) having structurally interacting inner and outer layers (4,3/104,103) joined together at mid-span and stretched in a V-shaped configuration between spaced-apart structural elements (9, 109). A linear gutter (2) can hang from the double-skin panel (22) at the junction of the inner and outer layers (4,3) thereof to drain water, thereby preventing ponding problems. The stressed paneling modules (22) may be supported by lightweight non-rigid tensely arched members (15, 16).

摘要:
A rigid structural member for a building in which the member has four sides each provided with a groove having narrow opening. Two of the grooves on two opposite sides be used to assemble structural members together to provide completed building assemblies by the use of screw-threaded members while, in the completed assembly, the other two grooves are used for holding two building enclosure sheets in spaced positions, one on each side of the completed assembly. For this purpose, elongate holding members are located in the grooves to hold the sheets in place. The holding members have a particular design which secures them in place within the grooves. The grooves are preferably T-shaped and are all of the same size and shape to increase the versatility. In addition, the structural member may be formed into building structures which are hinged together such that they may be in a collapsed condition for storage and transportation or may be relatively pivoted into an erected condition.
摘要:
A process for erecting an inflatable building structure which is especially adapted for housing plants. The process includes the steps of(1) installing a plurality of support posts in the ground or other suitable base;(2) attaching a roof structure formed from one or more inflatable membranes to the plurality of support posts; and(3) inflating the inflatable membrane.Preferably the inflatable membrane has peripheral rigid support members which are each attached to a row of associated posts. The roof structure formed from the inflatable membrane(s) together with rigid support members may be initially laid on the ground before being elevated. There also may be provided an upper securing cable extending across the top of the or each inflatable membrane which may initially be in a slack condition but which is subsequently tensioned before inflation. There also may be provided a lower support cable extending under the or each membrane which may initially be in a slack condition but which is subsequently tensioned before inflation. The invention also provides an inflatable building structure erected by the aforementioned process.
摘要:
A double-glazing assembly suitable for horticultural and agricultural growing houses comprises two flexible light-transmitting thermoplastics film, especially polyethylene terephthalate films, separated by a spacing framework. Means are provided to evacuate the enclosure between the sheets during the day-time thereby improving the light transmission of the assembly. The assembly is also preferably provided with means for inflation to optimise the conservation of thermal energy during the night-time.
摘要:
A system for securing the edges of plastic sheeting or the like is formed from metallic extrusions using three elements: a base element; an intermediate element; and a cap element. The base element is mounted to the surface to which the sheeting is to be attached and the cap element is placed over the sheeting and interlocks with the base element. If multiple sheets of plastic film are to be secured, intermediate elements may be used with the cap element installed to secure the top sheet. Tension on the sheetings serves to lock the elements in place.

A shelter for the growth of plants and the like is provided which shelter is comprised of panels. The panels are formed of films which are adapted to control the transmission of energy into the shelter and further adapted to control the flow of fluids stream into and out of the shelter.
摘要:
A device for holding flexible sheet material to a structure including a fixed element that is attachable to the structure and has at one end an elongated cavity and at the other end an intrinsic lock mechanism and a locking device having at one end an arm for holding sheet material against the interior portion of the cavity and for bearing against the open edge of the cavity, the locking element also having the second half of an intrinsic lock device that is adapted to snap into the intrinsic lock device half on the fixed element.
摘要:
A solar heated building comprising a frame, an inner wall supported by the frame, and an outer wall of generally transparent material supported by the frame and spaced outwardly of said inner wall thereby defining a passage therebetween. The passage has an inlet for the flow of air into the passage and an outlet in communication with the interior of the building for flow of air from the passage into the interior of the building. The inner and outer walls are positioned for incidence thereon of solar radiant energy, whereby on flow of air through the passage the air may be heated by the solar radiant energy prior to flowing into the interior of the building.
