A system formed by a composite beam and a composite plate

The invention relates to a system formed by a composite beam and a composite plate for use on roofs, subfloors or subfloors of buildings, comprising a composite beam, composite plates supported by it and a casting component, and in which the composite beam consists of one or more profile plates.

Composite plates and beams and their systems are known from, among others, 10 Finnish patent applications 862035, 863396, and American patent 2,064,910. In addition, the profile mold systems known from EP application publication 240857 and Finnish patent 63465 are extensively related to the scope of the invention. FI application 862035 proposes a system in which the mold 15 of a composite beam is formed by two galvanized steel sheets that are connected to each other from below. Casting is performed on the assembly formed by the composite plate and the composite beam, whereby a uniform structure is obtained. Here, the composite beam has to be reinforced separately, despite the fact that the joint points 20 at the bottom of the composite beam form the gripping edge. Reinforcement is needed both in the composite beam itself, to attach it to the composite plate and as top surface reinforcement at the beam. The object of the invention is to simplify the reinforcement of the system. In particular, it is desired to simplify the reinforcement connecting the composite beam and the plate and the upper surface of the slab 25. The main features of the invention are set out in the appended claims. The invention can also be applied when bolted structures are used in the system to bind different parts together. When these are placed sufficiently high and made sufficiently protruding, they then act at least in part as top surface reinforcement.

In the following, the invention is illustrated by the accompanying figures, which show some embodiments of the invention.

Figure 2 shows another embodiment 2 81166 The system comprises a composite beam profile 2 and composite plates 1 supported by an edge protrusion 3 of the beam profile. These remain inside the casting component 9 and act as the upper surface reinforcement of the continuous slab at the support. The transverse steel bars 8 are mounted through holes 5 made near the upper surface 4 of the composite beam profile 2. The connecting beam here includes prestressing elements-10 tit 6, 7 and 10.

Here, the transverse iron bars 8 have three functional functions. In addition to acting as the top surface reinforcement of the continuous slab at the support, they connect the slab to the composite beam 15 and thirdly, they act as an adhesion of the internal casting mass 11 of the composite beam to the composite beam profile 2.

The system according to the invention is applicable in various contexts. Figure 2 shows a system similar to Figure 1. Here, however, the composite beam profile 12 is slightly different from the shape of Figure 1. It comprises an outwardly bent step 15, on which the connecting plates 1 are placed. Here again, the operation of the transverse iron bars 8 corresponds to the operation of the system shown in Figure 1.

In particular, it should be noted that the composite beam profiles 2 can also be assembled from two or more parts, whereby the bolts used for assembling them can act as said transverse iron bars for performing one or more of said tasks.
