Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
A reinforced concrete column having side attachment means for a steel beam and comprising a steel anchor member which is short relative to the column and which is embedded in the concrete, and further comprising an elongated member extending lengthwise of said column, and at least two T-members having legs secured to said elongated member and the crossbars of said T-members being in the plane of a side face of said column and exposed thereat, and said crossbars having fixing bolt holes therein, which constitute means for attachment by means of bolts of the steel beam.
Claim 2
Dependent Claim
96 words
A reinforced concrete column having side attachment means for a steel beam and comprising a steel anchor member which is short relative to the column and which is embedded in the concrete, and further comprising an elongated member extending lengthwise of said column, and at least two T-members having legs secured to said elongated member and the crossbars of said T-members being in the plane of a side face of said column and exposed thereat, and said crossbars having fixing bolt holes therein, which constitute means for attachment by means of bolts of the steel beam.
Claim 3
Dependent Claim
47 words
A column as claimed in claim 1 wherein said anchor member comprises at least two further T-members having legs secured to said elongated member and having crossbars in the plane of a second Side face of said column, said last named crossbars having fixing bolt holes therein.
Claim 4
Dependent Claim
99 words
In a building frame, a reinforced concrete column having embedded in the concrete a metal anchor member which is short in relation to the column, said member having at least two plane surfaces in the planes of two differently orientated side faces of said column, said two plane surfaces being interconnected by, and secured to, at least one web embedded within the concrete with its plane extending lengthwise of the column, said plane surfaces being provided with bolt holes, and at least two steel beams bolted to said two plane surfaces respectively by bolts engaging in said bolt holes.
Claim 5
Dependent Claim
99 words
In a building frame, a reinforced concrete column having embedded in the concrete a metal anchor member which is short in relation to the column, said member having at least two plane surfaces in the planes of two differently orientated side faces of said column, said two plane surfaces being interconnected by, and secured to, at least one web embedded within the concrete with its plane extending lengthwise of the column, said plane surfaces being provided with bolt holes, and at least two steel beams bolted to said two plane surfaces respectively by bolts engaging in said bolt holes.
Claim 6
Dependent Claim
57 words
A building frame as claimed in claim 3 in which said anchor member comprises a short length of I-section steel joist, the flanges of the joist lying in the planes of a pair of opposed side faces of said column and providing the plane surfaces aforesaid and the web of the I-section being embedded in the column.
Claim 7
Dependent Claim
72 words
A building frame as claimed in claim 4 in which there is at least one T-member embedded in the concrete, the leg of the T member constituting a connecting web and being secured to the web of the I-section and the crossbar of the T member lying in the plane of a third side face of the column and having fixing holes, a further steel beam being bolted to said fixing holes.
