Abstract
Abstract A method of building construction which utilizes prefabricated floor elements and cast in situ support elements therefor. Forms are erected at horizontally spaced locations with each form defining a vertical support section and at least one horizontal support section. A prefabricated floor element is positioned on the horizontal support sections of the forms with the floor element partially spanning the horizontal distance between the vertical support sections of the forms. Concrete is then poured into the forms and, after setting, forms a support element having a vertical portion and at least one horizontal portion with the horizontal portion forming a rigid connection with the prefabricated floor element. The cast in situ support elements can be a wall, column or the like. After setting, the forms are removed and the process repeated in a horizontal and/or vertical dimension.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
122 words
A method of building construction comprising the steps of: 1. erecting at horizontally spaced locations at least two forms for a setable, plastic material, said forms each defining a vertical support section and at least one horizontal support section; 2. positioning a prefabricated floor element on the horizontal support sections of said forms, said floor element partially spanning the horizontal distance between the vertical support sections of said forms; 3. placing a setable, plastic material in each of said forms, said material forming in each form a support element having a vertical portion and at least one horizontal portion with the horizontal portion forming a rigid connection with said floor element; and, 4. removing said forms after said plastic material has set.
Claim 2
Independent Claim
122 words
A method of building construction comprising the steps of: 1. erecting at horizontally spaced locations at least two forms for a setable, plastic material, said forms each defining a vertical support section and at least one horizontal support section; 2. positioning a prefabricated floor element on the horizontal support sections of said forms, said floor element partially spanning the horizontal distance between the vertical support sections of said forms; 3. placing a setable, plastic material in each of said forms, said material forming in each form a support element having a vertical portion and at least one horizontal portion with the horizontal portion forming a rigid connection with said floor element; and, 4. removing said forms after said plastic material has set.
Claim 3
Dependent Claim
42 words
The method of claim 1 wherein said forms are erected at horizontally spaced locations such that the length of the prefabricated floor element will be within the range of 70 to 90 per cent of the distance between said vertical support sections.
Claim 4
Dependent Claim
27 words
The method of claim 1 wherein said forms are erected so that the resulting vertical portion of said setable, plastic material formed support element is a wall.
Claim 5
Dependent Claim
27 words
The method of claim 1 wherein said forms are erected so that the resulting vertical portion of said setable, plastic material formed support element is a column.
Claim 6
Dependent Claim
27 words
The method of claim 1 wherein said forms are erected so that the resulting vertical portion of said setable, plastic material formed support element is a frame.
Claim 7
Dependent Claim
51 words
The method of claim 1 further comprising erecting at horizontally spaced locations and in vertically alignment with two previously formed support elements two forms for a setable, plastic material, said forms each defining a vertical support section and at least one horizontal support section and, thereafter, repeating steps 2 through 4.
Claim 8
Dependent Claim
26 words
The method of claim 1 wherein said forms are erected so that the resulting vertical support element has a portion which extends above the horizontal portion.
Claim 9
Dependent Claim
12 words
The method of claim 1 wherein said setable plastic material is concrete.
Claim 10
Dependent Claim
63 words
The method of claim 1 wherein said forms each have two horizontal support sections positioned on opposite sides of said vertical support section and wherein said setable plastic material is placed in said forms to form a support element having a vertical portion and two horizontal portions with at least one of said horizontal portions forming a rigid connection with said floor element.
Claim 11
Dependent Claim
64 words
The method of claim 9 further comprising erecting at least three of said forms at horizontally spaced locations and positioning a prefabricated floor element between at least the first and second forms and the second and third forms on horizontal support sections thereof with said setable, plastic material formed horizontal portion support element forming a rigid connection with each of said prefabricated floor elements.
