Abstract:
The invention relates to a framework construction having low weight, high rigidity and strength and of the kind comprising beams (11) in the form of tubes, which are interconnected by means of joints (21) to form a three-dimensional frame structure. The beams (11) in their basic shape consist of two tubes (13) connected to one another by means of a web (14), forming an I-beam (12). The beams (11), depending on load conditions and demands for rigidity, are assembled from several I-beams, forming L, U and/or box-profiles or combinations thereof. In order to form the frame structure, at least the tubes (13) of the beams are connected to each other through tube joints (21) at the ends of the beams and/or along the length of the beam in regions (22) designed therefore. The tube joints (21) are non-rotationally mounted to at least the tubes.
Abstract:
The invention relates to a shaped element for use in a building construction and to a building construction erected using said shaped element. The aim of the invention is to produce a building construction which is simple and economical to erect and which can be taken down easily. To this end, the shaped element (2) has a connecting structure (19) which can be connected to a counter-structure (20) configured in a connecting area of another shaped element (2) with a positive fit. The shaped elements (2) can be interconnected with a positive fit in order to erect at least parts of the building construction using said shaped elements (2). Cavities (18) in the shaped elements (2) can be filled e.g. with water in order to improve the static of the building construction.
Abstract:
A modular building system (100) including preformed extrusion-molded polymeric material (116). Parts include integral connector elements (160, 162) which can be slidably and snappingly reversibly interconnected to form the basic frame (102) and panel structures (108) of an overall building. The interconnected region permits limited ranges of angular as well as translational relative motion between adjacent, connected elements. Parts are assembled simply and quickly in the field, without requiring skilled labor or specialized tools, to form a functionally solid and stable building which responds to loads and temperature changes with yieldable, accommodating deformations that minimize the likelihood of building structural damage, and effectively transmit necessary loads to the ground via load-transfer paths through the building.
Abstract:
This modular system consists of 9 particular profiles (1/3 Fig. 1, 2, 3, 4, 5, 6, 8, 10, 13) and 4 standard profiles (1/3 Fig. 7, 9, 11, 12), everybody will be available in different lengths with constant principal step equal to the side of the profile (1/3 fig. 10). It is possible to have the profiles of the system in different dimensions and each of the resultant groups will be compatible between them through to tubular profiles of telescopic connection. In particular three groups: small, medium and big; they have profiles that combine between them constituting a system modular complex. Like particular case the side of the profile (10) of the varied groups will have the length of 16mm, 32mm and 64mm and this will be also the modular step of the same profiles. The profiles (1/3 Fig. 1, 2, 3, 5, 13) present holes of fixing. The system has opened to the experimentation for realize prototypes and/or structures not only of furniture. Through the combination of the different profiles have gotten rigid or articulated joints, assembling and disassembling, eliminating the obligation of components produced for injection if are opted for the technique of the extrusion. The terminal closings of the profiles allow an adaptation and are in a particular case realized in metallic plate cut and folded up so as to get for elastic effect the connection of attrition in the inside of the same profiles.
Abstract:
A method of building which comprises taking honeycomb panels (as herein defined) having at least one flat edge for bonding to an adjacent structural unit, and bonding the panels and/or units together to form a composite building structure. The adjacent structural unit may be another honeycomb panel, or a beam, corner, or other desired unit. The honeycomb panel is preferably that of our European patent number 0 708 706. The honeycomb configuration of this structure makes it an ideal panel and it can be manufactured in an open or faced panel format. Furthermore it can be made in large sizes for example 0.9 m x 2.5 m and 40 mm thick. The panel can be modularised by constructing the fibre reinforcement into a narrow width panel preform, say 300 mm wide. At the moulding stage three fibre preforms can be loaded into an appropriate mould tool and a panel made of 900 mm width. A further property of the panel is that it acts like a beam in all directions, but is particularly effective as a beam when loaded on its edge. The construction of the panel may be such that the honeycomb format is always integrated into and bounded by a continuous straight edge. By effectively fastening a composite beam section such as a flat plate or box section to the edges of the panel, the properties of the panel, functioning as a beam, can be so enhanced as to make if effectively a beam.
Abstract:
An extrusion (22) for use in a floor assembly that is secured to a rigid underlying support (10, 12, 14). The extrusion has an exposed surface (30) and a base section (64) underlying the exposed surface. The extrusion is made of first extruded material, preferably a hard polyvinyl chloride (PVC) and more preferably a co-extrusion of a recycled polyvinyl chloride substrate (64) covered by a weatherable polyvinyl chloride capstock (66). The base section has at least a portion (102, 104, 106, 108) thereof including a second extruded material which is interposed between the plastic extrusion and the rigid underlying support when the plastic extrusion is secured to the rigid underlying support. The second extruded material resists undesired squeaking from occurring when weight bearing loads move on the floor assembly. A floor assembly adapted to be secured to an underlying rigid support and a complete floor assembly and rigid underlying support are also disclosed.
Abstract:
An I-beam structure (50) is made from discarded tire belts (14) wherein the beam web is constructed from two car or truck tire belts joined centrally along their lengths tread to tread (16). Flange members (45) are made of a single ply of truck tire belts joined end to end or of a two ply laminated structural material (40) wherein each ply is a continuous car tire belt, and the two plies are bonded tread to tread along their lengths. The flange forming members (45) are attached to the web by adhesive or vulcanization bonding which may be reinforced with mechanical fasteners.
Abstract:
The invention concerns a plastic composite profiled girder, in particular an aircraft wing spar, comprising at least two chords (1) with bonding flanges and at least one web (2) inserted into the bonding flanges and connecting the chords (1) to each other. The chords (1) are made from resin-impregnated rovings and the web (2) is made from resin-impregnated wovens or lay-ups, and the chords (1) and web (2) are joined to each other by adhesive bonding. The chords (1) are produced by pultrusion, the web (2) being inserted into the bonding flange of both chords (1) and fixed there using a thixotropic adhesive (4). This construction ensures that the full flange bonding width is maintained even if the height of the component is varied.

Construction elements of predetermined cross-sectional profiles are formed of wood, plastic and/or metal. These construction elements are useful in building construction, preformed panel systems and preformed truss structures. The shapes of the construction elements are also adaptable to a toy construction set.
