Description
SPECIFICATION
Reinforcement for concrete structures
This invention relates to a reinforcement unit capable of transmitting transverse forces in reinforced concrete structures and having a plurality of steel reinforcement rod lengths and at least one longitudinal connecting member for the reinforcement rod lengths, in which the reinforcement rod lengths run substantially orthogonally to the longitudinal direction of the connecting member and are secured thereto, and can be built into a reinforcement grid, for example by setting them up on timbering.
The term reinforced concrete structure includes the pre-stressed type. Reinforcement grids include all the reinforcement systems commonly used in reinforced concrete structures. The reinforcement rod lengths can be provided at their ends with plates, heads or other shaped members or bends. They can be fitted with spacers to determine their distance from the timbering.
In known reinforcement units of this type (DE-PS 27 27 159, DE-OS 30 1 5 407), the connecting member is a rigid longitudinally extending component, integrated in the static sense in the reinforcement within the reinforced concrete structure. In one such embodiment, the connecting member is a length of flat steel to which the reinforcement rod lengths are welded. The reinforcement unit acts as a thrust reinforcement for flat roofs of plain or pre-stressed reinforced concrete laid on concrete stanchions and is disposed on a radius from the stanchions, the flat steel lengths lying on the radii. In the other embodiment, the length of flat steel is replaced by rigid steel reinforcement rods, which as it were form a lower chord of the reinforcement unit.The known reinforcement units are neither capable of nor designed for deforming in the longitudinal direction defined by the connecting member, so as to assume on the construction site a zigzag, circular, rectangular or other like shape relative to the direction in which the reinforcement rod lengths are arrayed. The fabrication of the known reinforcement units is costly because of the welding operations. The reinforcement units themselves are unwieldy, and can therefore only be transported, handled and installed on site with difficulty.
In this context, the object of the invention is to provide a reinforcement unit of the type initially described that is simple from both the fabrication and the manipulation viewpoints, and furthermore adapatable so that on the construction site it can assume a zigzag or a circular, rectangular or square array, as required for the static strength of the component.
According to the present invention, the connecting member is formed as a flexible component, so that the reinforcement rod lengths can be laid close together or used in a zigzag, circular, rectangular or other array in concrete.
Laid close together refers more particularly to zigzag grouping, but also to coiling, for example coiling on themselves or on a drum.
The connecting member can consist of a plastics strip with slits or pockets into which the reinforcement rod lengths are inserted. In this case, one can use welded joints, which can easily be produced in thermoplastic materials. However, the reinforcement rod lengths can also be secured to the connecting member by means of binding wires or clips.
The connecting member itself can also take the form of thin metal strip or wire netting. In the context of the invention, flexible means that the connecting member can bend sufficiently to allow coiling, uncoiling and the various arrays referred to, including variations in the spacing of the reinforcement rod lengths by deforming the connecting member.
The accruing advantages are to be seen in that the reinforcement unit of the invention can be fabricated and manipulated more simply than the known embodiments. A particular advantage arises from the fact that on the construction site the reinforcement unit can be arranged in a zigzag, circular, rectangular, square or other shape, as dictated by the static strength requirements of the reinforced concrete structure.
Embodiments of the invention will now be described, by way of example only, with reference to the accompanying diagrammatic drawings, in which: Figure 1 is a side elevation of a reinforcement unit in accordance with the invention;
Figure 2 is a plan view of the unit of Fig. 1;
Figure 3 corresponds to Fig. 1 but shows another embodiment;
Figure 4 is a plan view of a reinforcement unit in accordance with the invention in a coiled condition; and
Figure 5 shows alternative arrangements a, b and c for reinforcement units in accordance with the invention.
The reinforcement units shown in the Figures are intended for reinforced steel structures, such as slabs with supports, girders and walls and are capable of transmitting transverse forces. In basic construction they each consist of a plurality of steel reinforcement rod lengths 1 and at least one longitudinal connecting member 2 for the reinforcement rod lengths. The reinforcement rod lengths 1 run substantially orthogonally to the longitudinal direction of the connecting member 2, to which they are secured.
By comparing Figs. 1 and/or 3 on the one hand with Fig. 4 on the other hand, it will be seen that the connecting member 2 is formed as a flexible component, so that the reinforcement rod lengths 1 in the embodiment shown can be disposed in a coiled array and uncoiled at the construction site. At the construction site they may be arranged in a straight array as in Fig. 2, or zigzag, circular, square, rectangular or other array, as shown in Fig. 5 arrangements a to c.
In the embodiment shown in Fig. 1, each of two connecting members 2 takes the form of a plastics strip, while in the embodiment shown in Fig. 3, the connecting member 2 is a strip of wire netting, the reinforcement rod lengths 1 being secured to the strips 2 with binding wire, but other methods could alternatively be adopted.
