Abstract
Abstract A method of constructing a multi-storey building comprises the steps of laying a foundation ring beam for the external walls of the building, erecting a plurality of ground floor columns around the foundation ring beam, the ground floor columns being supported by the foundation ring beam and extending over substantially the height of the ground floor of the building, placing panels between the adjacent pairs of ground floor columns to form the external walls of the ground floor storey of the building, and constructing the higher storeys of the building successively one upon another. Each of the higher storeys is constructed by erecting a plurality of columns around the building, each of said columns being supported by a respective column of the storey immediately below and extending over substantially the height of that storey; supporting a floor on the upper edges of the wall panels of the storey immediately below, and by placing panels between the adjacent pairs of the columns to form the external walls of that storey. The uppermost storey of the building is covered by a roof which is supported on the upper edges of the wall panels of that storey. Each of the panels may comprise a core of reinforced concrete housed within a sheath made of non-corrosive material. The sheath constitutes a mold for casting the core and a permanent protective convering for the core when the concrete has been cured.

Claim 1
Independent Claim
205 words
A method of constructing a multi-storey building comprising the steps of laying a foundation for the external walls of the building, erecting a plurality of ground floor columns around the foundation, the ground floor columns being supported by the foundation and extending over substantially the height of the ground floor of the building, placing panels between the adjacent pairs of ground floor columns to form the external walls of the ground floor storey of the building, and constructing the higher storeys of the building successively one upon another, wherein each of the higher storeys is contructed by erecting a plurality of columns around the building, each of said columns being supported by a respective column of the storey immediately below and extending over substantially the height of that storey, by firmly clamping the wall panels of the storey immediately below in position, by then supporting a floor on the upper edges of the wall panels of the storey immediately below, and then by placing panels between the adjacent pairs of said columns to form the external walls of that storey, the uppermost storey of the building being covered by a roof which is supported on the upper edges of the wall panels of that storey.
Claim 2
Independent Claim
205 words
A method of constructing a multi-storey building comprising the steps of laying a foundation for the external walls of the building, erecting a plurality of ground floor columns around the foundation, the ground floor columns being supported by the foundation and extending over substantially the height of the ground floor of the building, placing panels between the adjacent pairs of ground floor columns to form the external walls of the ground floor storey of the building, and constructing the higher storeys of the building successively one upon another, wherein each of the higher storeys is contructed by erecting a plurality of columns around the building, each of said columns being supported by a respective column of the storey immediately below and extending over substantially the height of that storey, by firmly clamping the wall panels of the storey immediately below in position, by then supporting a floor on the upper edges of the wall panels of the storey immediately below, and then by placing panels between the adjacent pairs of said columns to form the external walls of that storey, the uppermost storey of the building being covered by a roof which is supported on the upper edges of the wall panels of that storey.
Claim 3
Dependent Claim
48 words
A method according to claim 1, wherein each column of each of the higher storeys is connected to the respective column of the storey immediately below by means of a tubular connector, the tubular connector being externally threaded and engaging with internally-threaded end portions of the two columns.
Claim 4
Dependent Claim
77 words
A method according to claim 2, wherein each tubular connector is screwed into the lower of its associated columns, an apertured joint plate is placed round the connector and overlying the upper edges of the two wall panels of the storey immediately below, and the upper of its associated columns is then screwed down onto the connector so as to force the joint plate down against said panel upper edges thereby clamping said panel firmly in position.
Claim 5
Dependent Claim
16 words
A method according to claim 1, wherein the ground floor columns are equispaced around the foundation.
Claim 6
Dependent Claim
31 words
A method according to claim 1, wherein the foundation is a foundation ring beam made by pouring concrete into a formwork positioned within a foundation excavation, the formwork containing reinforcement members.
Claim 7
Dependent Claim
22 words
A method according to claim 1, wherein the bases of the ground floor columns are housed in respective recesses in the foundation.
Claim 8
Dependent Claim
16 words
A method according to claim 1, wherein all the wall panels have the same basic shape.
Claim 9
Dependent Claim
19 words
A method according to claim 1, wherein the panels are prefabricated and are placed in position using a crane.
Claim 10
Dependent Claim
40 words
A method according to claim 8, wherein each of the panels is made of concrete cast into aluminium moulds, and wherein the moulds are left in place after the concrete has been cured so forming integral parts of the panels.
Claim 11
Dependent Claim
23 words
A method according to claim 6, wherein each of the columns and each of the ground floor columns is made of tubular steel.
Claim 12
Dependent Claim
26 words
A method according to claim 10, wherein the recesses in the foundation are formed by drilling holes in the foundation after the concrete thereof has cured.
Claim 13
Dependent Claim
32 words
A method according to claim 1, further comprising the step of constructing a floor for the ground floor storey between the steps of forming the foundation and erecting the ground floor columns.
Claim 14
Dependent Claim
16 words
A method according to claim 12, wherein said floor is made by casting a concrete slab.
Claim 15
Dependent Claim
38 words
A method according to claim 1, wherein the floor of each higher storey is made by laying profiled floor sheets over the entire area of the building and by casting a slab of concrete over said floor sheets.
Claim 16
Dependent Claim
34 words
A method according to claim 1, wherein the roof is made by laying profiled roof sheets over the entire area of the building and by casting a slab of concrete over said roof sheets.
Claim 17
Dependent Claim
42 words
A method according to claim 15, wherein a layer of rigid polyurethane foam is fixed to the top surface of the roof slab, and a layer of waterproof cement is laid on the top surface of said layer of rigid polyurethane foam.
Claim 18
Dependent Claim
20 words
A method according to claim 1, further comprising the steps of constructing internal walls within each storey of the building.
Claim 19
Dependent Claim
