Abstract

In a space structure comprising a multiplicity of separately formed elongate members interconnected at their ends at a plurality of mutually spaced connection positions or nodes by separately formed node connectors to form a lattice-work structure, each elongate member is made of resin bonded glass or other inorganic reinforcing fibre. Preferably, each node connector is also made of resin bonded glass or other inorganic reinforcing fibre or, if made of steel or other metal or metal alloy, has a coating or covering layer of corrosion- resistant non-metallic material. At least some of the elongate members may be of tubular form.

Description

SPECIFICATION Improvements In or Relating to Space Structures This invention relates to space structures of the kind in which a multiplicity of separately formed elongate members are interconnected at their ends at a plurality of mutually spaced connection position or nodes by separately formed node connectors to form a lattice-like structure. Space structures of this kind will hereinafter be referred to as "space structures of the kind described".
In addition to their obvious use as scaffolding and other supporting structures for building purposes, space structures of the kind described are used in the construction of roofs of buildings for many different purposes including industrial buildings, supermarkets, shops, and other commercial buildings, raiiway stations and other transport buildings, sports stadia and halls and swimming baths.
It is the general practice to employ for the elongate members of a space structure of the kind described tubes or rods of metal or metal alloy, usually steel or aluminium, which are interconnected at the nodes by node connectors of metal or metal alloy. In most cases a space structure of the kind described made of steel or other metal or metal alloy is perfectly satisfactory, but where the space structure is to form the roof of a building or a cover over an area where the space structure is likely to be subjected to a corrosive atmosphere which will attack and ultimately weaken the component elements of the space structure, such as the roof of a chemical plant, brewery or swimming bath or a cover over a reservoir, the length of time the space structure can be in service before it must be replaced or repaired is limited and regular inspection of the structure must be made to ensure that the structure can be repaired or repiaced before there is any danger to human life due to collapse of the structure.
It is an object of the present invention to provide a space structure of the kind described in which the risk of deterioration of the structure due to a corrosive atmosphere is eliminated or at least substantially reduced.
According to the present invention, in our improved space structure of the kind described, each elongate member is made of resin bonded glass or other inorganic reinforcing fibre.
In most cases, to maintain the weight of the space structure as low as possible, preferably some or all of the elongate members are of tubular form.
Preferably, each node connector is also made of resin bonded glass or other inorganic reinforcing fibre so that there is substantially no metal or metal alloy present in the structure. A preferred node connector has a plurality of threaded holes whose axes meet at or near the centre of the connector and in each of which is detachably secured a connector bolt which is in axial alignment with and rotatably mounted at an end of an elongate member.
Where a bolt rotatably mounted at the end of an elongate member is of steel or other metal or metal alloy, preferably its exposed surfaces are coated with or are covered by a layer of a nonmetallic material that is resistant to a corrosive atmosphere.
The invention also includes, for use in the construction of a space structure of the kind described, a node connector made of resin bonded glass or other inorganic reinforcing fibre or made of steel or other metal or metal alloy and having a coating or covering layer of corrosionresistant non-metallic material.
The invention further includes, for use in the construction of a space structure of the kind described an elongate member of resin bonded glass or other inorganic reinforcing fibre having rotatably mounted at each of its ends and in axial alignment with the member a connector bolt or other elongate connection means for connection to a node connector of a space structure.

SPECIFICATION Improvements In or Relating to Space Structures This invention relates to space structures of the kind in which a multiplicity of separately formed elongate members are interconnected at their ends at a plurality of mutually spaced connection position or nodes by separately formed node connectors to form a lattice-like structure. Space structures of this kind will hereinafter be referred to as "space structures of the kind described". In addition to their obvious use as scaffolding and other supporting structures for building purposes, space structures of the kind described are used in the construction of roofs of buildings for many different purposes including industrial buildings, supermarkets, shops, and other commercial buildings, raiiway stations and other transport buildings, sports stadia and halls and swimming baths. It is the general practice to employ for the elongate members of a space structure of the kind described tubes or rods of metal or metal alloy, usually steel or aluminium, which are interconnected at the nodes by node connectors of metal or metal alloy. In most cases a space structure of the kind described made of steel or other metal or metal alloy is perfectly satisfactory, but where the space structure is to form the roof of a building or a cover over an area where the space structure is likely to be subjected to a corrosive atmosphere which will attack and ultimately weaken the component elements of the space structure, such as the roof of a chemical plant, brewery or swimming bath or a cover over a reservoir, the length of time the space structure can be in service before it must be replaced or repaired is limited and regular inspection of the structure must be made to ensure that the structure can be repaired or repiaced before there is any danger to human life due to collapse of the structure. It is an object of the present invention to provide a space structure of the kind described in which the risk of deterioration of the structure due to a corrosive atmosphere is eliminated or at least substantially reduced. According to the present invention, in our improved space structure of the kind described, each elongate member is made of resin bonded glass or other inorganic reinforcing fibre. In most cases, to maintain the weight of the space structure as low as possible, preferably some or all of the elongate members are of tubular form. Preferably, each node connector is also made of resin bonded glass or other inorganic reinforcing fibre so that there is substantially no metal or metal alloy present in the structure. A preferred node connector has a plurality of threaded holes whose axes meet at or near the centre of the connector and in each of which is detachably secured a connector bolt which is in axial alignment with and rotatably mounted at an end of an elongate member. Where a bolt rotatably mounted at the end of an elongate member is of steel or other metal or metal alloy, preferably its exposed surfaces are coated with or are covered by a layer of a nonmetallic material that is resistant to a corrosive atmosphere. The invention also includes, for use in the construction of a space structure of the kind described, a node connector made of resin bonded glass or other inorganic reinforcing fibre or made of steel or other metal or metal alloy and having a coating or covering layer of corrosionresistant non-metallic material. The invention further includes, for use in the construction of a space structure of the kind described an elongate member of resin bonded glass or other inorganic reinforcing fibre having rotatably mounted at each of its ends and in axial alignment with the member a connector bolt or other elongate connection means for connection to a node connector of a space structure.
