Definitions
- the invention relates to a truss for the reinforcement of walls or ceilings consisting of casting compounds, consisting of two longitudinal straps and diagonal bars running between them, the diagonal bars being formed by a steel strip which is bent in a zigzag shape and which extends at its bends with the same Sheet steel belts are connected to existing profiled longitudinal belts.
- the invention has set itself the goal of creating a truss of the type mentioned that is easy to manufacture and still largely rigid.
- a supporting structure should also be able to be formed from such trusses in a simple manner.
- the width of the sheet steel strip of the diagonal bars which is also channel-shaped, and the width of the longitudinal straps extend transversely to the longitudinal center plane of the truss and that the steel sheet strip of the diagonal bars has a piece running parallel to the longitudinal straps in the region of the nodes.
- the sheet steel strip can be obtained by cutting galvanized sheets and then deformed. Since the zinc also has the property of migrating to the cut edges, these cut edges are also protected against corrosion.
- a structure made of truss girders according to the invention can be formed in a simple manner by spacing the longitudinal belts Have bores and at least two approximately parallel truss girders are connected by spacers also provided with bores by means of connecting elements seated in the bores, the spacers consisting of a galvanized sheet steel strip.
- connection of the longitudinal belts to the spacers does not need to absorb large forces, it only serves to secure the truss girders inserted into a mold, a casting compound, in particular concrete or lightweight concrete, being subsequently poured into the mold.
- the connecting members are designed as plastic plugs which have resilient tabs provided with a shoulder which spring into the bores when they are inserted and then spring back. Such plastic plugs only need to be pressed into the holes and then ensure the cohesion of the longitudinal belts with the spacers.
- the plastic plugs can also be used by a simple measure to achieve a safe embedding of the structure in the casting compound.
- This simple measure consists in the fact that the plastic plugs protrude beyond the spacers on the side opposite the tab. Therefore, the plastic plugs inevitably maintain a distance between the walls of the mold and the structure.
- FIG. 1 shows a structure according to the invention made of truss girders and
- FIG. 2 shows the side view of a truss girder.
- FIG. 3 shows, on an enlarged scale, a section through the connection point between a longitudinal belt and a spacer.
- a truss consists of two longitudinal straps 1 and 2 and diagonal bars 3 running between them. Both the longitudinal straps 1 and 2 and the diagonal bars 3 each consist of a galvanized sheet steel strip which is deformed in a channel shape.
- the diagonal bars 3 are somewhat narrower than the longitudinal belts 1 and 2 and are formed by a continuous sheet steel strip which is connected to the longitudinal belts at the nodes 4 by pressing. The bulges formed during the pressing are denoted by 5 in FIG. 2.
- the sheet steel strip of the diagonal bars 3 in the area of the nodes 4 has a parallel to the Longitudinal straps 1 and 2 extending piece in which the steel sheet band and the longitudinal straps 1, 2 are pressed together.
- Truss girder interconnected by spacers 6 are of the same design as the longitudinal belts 1, i.e. they consist of a galvanized sheet steel strip and have the same shape and
- Spacers 6 are made by means of plastic plugs 7, which have resilient tabs 8.
- a shoulder 9 is provided in the area of the resilient tabs 8 and a cylindrical part 10 extends opposite the tabs 8 and ends in an all-round shoulder 11. In the area of the flap 8
- Both the longitudinal belt 1 and the spacer 6 are provided with holes 12 through which the plastic plug 7 is inserted.
- a kind of snap fastener can also be used to connect the spacers 6 to the longitudinal belts 1, 2.
- the sheet steel strip can have further, but also other deformations or bends, by means of which the strength can be increased.
