Definitions

  • the present application relates to a steel-reinforced concrete building structure according to the preamble of claim 1.
  • pre-cast concrete there are many other limitations concerning the usage of pre-cast concrete, such as only one-way loading (to the two opposite supporting walls or beams, i.e. in a hollow core pre-stressed pre-cast) and the inability to get a rigid continuous floor slab or a smooth ceiling surface or one that could extend rigidly and continuously , in both horizontal directions.
  • an "off the shelf' panel was needed which fits almost anywhere and is designed for this kind of loading, a panel where the structure can be built an the wiring done later on without any disturbances of the panel or any adjacent panels, one where large openings on one side or even an open space garage or mall with standard panel size would be constructed with high speed and ease.
  • US 1,516,074 A shows a reinforced concrete building construction.
  • a column is integrally casted with a capital having four sides with a stepped rim.
  • reinforcing elements in form of steel bars are provided.
  • T-girders In this previously disclosed construction load on the floor is transmitted via T-girders to the columns only by bearing forces. It is not possible to transmit bending moments of a noteworthy degree.
  • US 1,516,074 A shows all the features of the preamble of claim 1 and of the preamble of claim 4.
  • a steel-reinforced concrete building structure comprising at least four vertical supports, each support consisting, in use, a vertical column and a square pre-cast horizontal panel centered on the top of the column, is provided as disclosed in claim 1.
  • This structure evenly distributes the load of the floor slab to each column and consequently to the four walls enclosing the area; thus the affecting load of each support structure is reduced. This effect results in thinner walls and thinner columns which allows a more flexible design of the building. Also extra stories are possible in comparison to buildings according to the state of the art because of the reduced weight and height of the slabs.
  • the column of the support is formed as an hollow column having a steel cage along its longitudinal axle to be filled with concrete. These columns are penetrating the whole building uninterrupted from footing to the roof.
  • the size of columns and slabs are reduced providing an higher erection speed, light weight and longer spans with less slab thickness and nonetheless a strong rigid slab.
  • the continuous steel columns from footing to the roof reduces the wall or columns size since the columns are not pinned at the top and the bottom of each floor. This is especially advantageous where smaller columns are desirable as in shopping malls, theaters or office buildings.
  • the column in form of a rectangular panel is an integral part of the horizontal panel creating a "T"-shaped cross-section of the pre-cast panel.
  • the column or support of the horizontal panel constitute a part of the wall and the horizontal panel a part of the floor of the building when a plurality of pre-cast panels were connected by means of i.e. flexible steel connections. Additionally there are shafts (or ducts) running vertically through the support of each pre-cast panel.
  • the slabs are rigidly resting on walls or columns with the freedom of movement continuity of moment in slabs connected by hinges to the wall below.
  • this system is ideal for high rise buildings providing a high erection speed, light weight and longer spans with less slab thickness although a strong rigid slab is provided that can transfer wind and earth quake forces to a central core shear wall.
  • the walls and columns in high rises do not carry additional slab moments from each floor, therefore they do not have to be enlarged unnecessarily since the slabs are monolithic and rigid enabled to carry the lateral forces to the building core that is designed to handle it.
  • This panel which does not form part of the invention, is used to construct buildings having essentially horizontal planes (floor slabs) penetrated by vertical walls (or columns).
  • the planes are rigid and inflexible and are preferably connected to an intersecting plane by means of a hinge connection. Due to this flexible connection no moment is transferred to walls or columns which is advantageous in high rises were axial loadings are already excessive. This is also true for large slabs that can exert considerable moments onto columns in the case the connection between slab and column is very stiff. Since the slabs resting on walls and/or columns do not transfer moments to the vertical members or do receive moments, large building may be constructed by using single-size pre-cast panels that fit almost all the cases. Due to the panels rigidity the moments are redistributed and partly transferred to adjacent slabs.
  • the column consists of an exterior concrete shell. This further increases the bearing capacity of the column.
  • the height of the stepped rim is basically half of the height of the panel.
  • the reinforcement elements are steel bars penetrating the pre-cast panel of the support in vertical pairs parallel to the upper and the lower surface of the pre-cast panel.
  • the steel bars are connected to the floor slab which preferably also consists of such reinforcement elements, which distribute the load and the moments to the supports.
  • the floor slab to be positioned on the horizontal slab is pre-cast. This allows a quick erection of the building.
  • the pre-cast floor slab is positioned on one corner of the stepped rim of the pre-cast panel.
  • the pre-cast floor slab is positioned on two adjacent stepped rims.
  • the steel bars of the pre-cast-panels form a support grid where the floor slab is cast onto.
  • Fig. 1 shows four supports 1 with a column 2 having a pre-cast panel 3 on its top.
  • the square panel 3 is stepped down to half of its thickness, forming a stepped rim 4 with a width of about 10 cm.
  • the stepped rim 4 is reinforced by means of steel bars 5 running horizontally and parallel through the panel 3 and protruding about half a meter on all four sides in vertical pairs close to the top and the bottom panel 3 surfaces.
  • the hollow column 2 is centered below the pre-cast panel 3 and fixed by means of a flexible pinned connection to the panel 3 above.
  • a steel cage 6 in the middle of the column 2 is filled with concrete either at site or pre-cast with an exterior concrete shell 7.
  • a grid 8 made of reinforcing steel-bars is formed between the four supports 1.
  • Fig. 2 depicts another embodiment not being part of the invention of an steel-reinforced concrete building structure 10 having a square pre-cast panel 30 which is reinforced by reinforcing elements like steel bars 50. Below the pre-cast panel 30 a rectangular support 20 is positioned below the pre-cast panel 30 .
  • This support 20 consists of concave cavities 60 along its borders which are arranged perpendicular to the pre-cast slab 30 and serve for the acceptance of IT and electric cables.
  • Fig. 3 still another embodiment not being part of the invention of a steel-reinforced concrete building structure 10 is shown wherein the pre-cast panel 30 is of an rectangular shape.
  • Figs. 4A to Fig. 4E describe the embodiment of Fig. 3 in further details.
  • Fig. 4A is a cross-sectional view of the building structure 10 wherein steel bars 50 protrude the stepped part and the larger part of the pre-cast panel 30 as well.
  • Fig. 4B the pre-cast panel 30 is shown from above. Again the protruding steel bars 50 are shown which are running in parallel through the pre-cast panel 30. In the middle of the smaller side of the pre-cast panel 30 there is a concave cavity 60 for the acceptance of IT and electric cables. Hollow shafts 70 are running through the support 20 perpendicular to the pre-cast panel 30.
  • Fig. 4C two pre-cast panels 30 which are connected to each other are shown from above.
  • a cross-sectional view of four building structures 10 forming two stories within a building is described.
  • two adjacent supports 20 were connected by a flexible conduit 80 for example made of PVC or flexible steel.
  • the PVC conduits run horizontally on either side of the wall at about 30 cm and 110 cm from the bottom ending at concave cavities 60 of the supports 20 which are used for IT and electric cables.
  • the conduit 80 can also be used to connect by wiring the slabs in the center of the room, the slabs to an other side of the room, to the floor below as to the floor above, as well as rooms on each side of the support.
