Prefabricated parts set for the construction of paved surfaces

The invention relates to a prefabricated part for the construction of paved surfaces, such as roadways, Landing runways, depot areas or the like, consisting of parallel at a distance next to each other, transversely to edge supports or Boundaries of the roadway, runway or the like. Support beams to be arranged, attachable to them and parallel to Profiled stiffening beams running along the edge supports and covering panels that can be placed on them.

Such a set of components made of steel is

already known. ^ j

Furthermore, a set of components is known in which on the foundations anchored in the ground as boundaries of the roadway or serving as edge stubs longitudinal beams are arranged in the longitudinal direction of the roadway and combined with supporting beams serving as cross beams to form a prestressed concrete framework, over the cross beams are 10 m long, very heavy bearing tokens laid, the ale underlay for the actual road surface. Although calibrated

such prefabricated parts sets are advantageous distinguish the fact that roads can be reached relatively quickly with them, is the use sohwerer supporting decks, which have to provide the necessary load-bearing capacity, are perceived as a disadvantage, since these are only transported using extremely large construction machines or transport machines can be.

It is also already known to use plastic sheets in the To use road construction and to attach them to concrete piles. It is also known, composite building boards from synthetic resin concrete and an insulating, brick or other building material as a second layer. Finally, it is known to use semicircular profile girders directly in the soil sando layer when building roads embed or put on the substrate and the gaps between the beams to fill with building material and to lay the paving slabs over the surface leveled in this way.

The invention is based on the object of providing a set of prefabricated components for the rapid construction of paved surfaces create, which is on the one hand easy and, above all, quick to lay, on the other hand through low weight and ultimately characterized by great resilience.

The invention consists in the combination of the following features:

The supporting beams point towards the facing plates Top side recesses at a distance from each other

on; in the recesses are located such einsetsbar _s that they conclude across several support beams, for example in road longitudinally extending stiffening carrier flush with the support beam upper side, and the covering panels are designed as sandwich panels and have at least one glass fiber-reinforced plastic layer and a resin concrete layer.

It is particularly useful to use the stiffening beams

train with an inverted hat-shaped profile, m

so that this m in appropriately shaped recesses

can be used on the top of the supporting beam and there can be well anchored.

The V _e rstärkungsträger are preferably made of glass fiber reinforced plastic, preferably polyester or epoxy resins or Butadienmischpolymerisatharzen. If necessary, reinforcement beams made of aluminum or steel can also be used.

The reinforcement beams and the decking plates are in

usually separate parts of the prefabricated parts set; j

Advantageously, the reinforcement beams; jedoeh ™

also with the covering plate by gluing and / or {|

Rivets must be firmly connected. This enables a To relocate part of the laying work from the construction site to the factory.

According to a preferred feature of the invention are in the inversely hat-shaped profiled reinforcement beams Pipe pieces of appropriate length with pipe connectors known per se for receiving cables

or anchored as supply lines »piping Measure enables; when laying the prefabricated components, the simultaneous production of any necessary Supply lines without any special additional effort. Can also be used in the reinforcement beams Radiators or fasteners for cables, pipes or electrical radiators, e.g. heating foils or heating grids, which can be retrofitted, provided the reinforcement beams are provided as components of the prefabricated component set that are separate from the facing plates. The Against moisture and heat insulating effect used by reinforcement beams made of plastics will.

A method for the rapid construction of _t roads or the like on sandy or loamy subsoil using a set of prefabricated components according to the invention is, for example, that the subsoil is solidified by a synthetic resin, for example based on polyurethane or epoxy-polyamide, and the Covering plates and reinforcement beams before this synthetic resin hardens. relocated with partial insertion in this.

A preferred embodiment of the invention is shown in the drawing. In it are:

Fig. 1 is a view of a covering plate with inverted hat-shaped reinforcement beams on the underside in the longitudinal direction of the street, i.e. in the direction of these reinforcement beams;

2 shows a corresponding view of a support beam with cutouts for receiving the reinforcement beams;

Fig. 3 is a view of the support beam from above and Fig. 4 is a perspective view of a portion of a laid surface mount made of prefabricated parts according to the invention with partially broken away covering.

Fig. 1 shows the facing plate 1, consisting of a glass fiber reinforced plastic layer 2 and one artificial concrete layer on top 3.

On the underside of the Belqgplatten 1 are reinforcement beams 4 arranged, the profile of which is inverted hat-shaped. Depending on the static requirements, a or several such reinforcement beams 4 can be provided. These consist primarily of glass fiber reinforced Plastic.

According to FIGS. 2 and 3, the supporting beam 5 is made of concrete. In the upper surface of the support beam 5 there are recesses 6, which correspond to the profile of the reinforcement beams 4 are formed and arranged at appropriate intervals from one another.

The connection of the reinforcement beams 4 with the facing plates 1 as well as the connection of both the reinforcement beams 4 and the facing plates 1 with the support beam 5 can be done by gluing.

While the distance 7 between two adjacent support beams 5 with a thickness of a glass fiber reinforced Covering slab 1 of 8 mm was at most 15-20 cm, it is with the prefabricated components according to the invention Fig. 4 possible, this distance 7 to 30 cm up to 1 m to increase. This distance 7 is exclusively dependent

on the number of reinforcement beams 4 per meter of panel width, on the section modulus of the cross-sectional profile and of the flexural strength of these reinforcement beams 4. The edge supports 8 serve as Abutment for the supporting beams 5.

Over the width of the covering plate 1 or over the length of the support beam 5, reinforcement beams 4 different cross-sectional design and / or different material can be used. It however, it is advisable to design their cross-section in accordance with the recesses 6 of the supporting beams 5.

Inside the inverted, hat-shaped reinforcement beams Depending on your needs, you can use pipes, radiators, cables or fasteners for such be anchored. Pipelines built into the prefabricated components are especially of the same length as the Reinforcement beams are used, they can preferably be equipped with pipe connecting means known per se so that only the pipe connection has to be made on site. In practice you will Let the pipes protrude from the reinforcement beam of facing plates to be joined, the pipe connection Finish with the decking panels pulled apart and then push the decking panel closer, whereby the tube within the reinforcement beam does not participate in this movement of the covering plate, so that after the pipe on the other when the deck plate is pushed up The end of the reinforcement beam protrudes and thus in turn is ready to make the next pipe connection when the next facing plate to be attached is ready the tube is pulled far enough out of the reinforcement beam.

If the reinforcement beams are delivered as separate parts of the prefabricated component set, the Installation of pipelines, cables, heating equipment or the like in the reinforcement beams equipped with appropriate fastening means be carried out on the construction site before they are attached to the paving slabs.
