Description

The present invention provides a structure for replacing a beam containing a beam, preferably to relieve the load of a beamed timber beam. The slab comprises beams supporting the supporting structure, optionally bridging elements, filling and cladding, the relief structure having reinforced concrete strips located between the original beams and reinforced concrete strips directly or indirectly attached to the original beams.

In construction practice, the load-bearing structure of loft ceilings and intermediate ceilings is mostly beams supported by masonry. The beams are either closely spaced or spaced apart. In the latter case, the free spaces between the beams are covered in some conventional manner, e.g. wooden beams with decking, steel beams with brick vaults and reinforced concrete beams with ceramic or concrete lining bodies.

In the case of slab structures, their load-bearing capacity may not meet the needs and expectations. This is especially true for slabs containing wooden beams, which lose their load-bearing capacity as a result of aging or otherwise destroying the wood. The decay of wooden beams most often occurs when they are resting on the walls. In such cases, it is necessary to increase the load-bearing capacity of the slabs or to replace the slab structures.

There are many methods known to increase the load-bearing capacity of slabs. They are characterized by the addition of a load bearing support structure to the existing slab structure. The auxiliary structure is placed either below or above the existing slab structure. Generally, auxiliary structures placed under the original slabs are made using dry technology, while those placed above the slabs are made using wet technology. One of their advantages is that the main walls and slabs of the building do not have to be demolished and it is usually possible to preserve other structures in their original state.

Their disadvantage is that the thickness of the load-bearing part of the slab structure is definitely increased. Reinforcement from below will reduce ceiling height and from above will not restore original flooring. A further disadvantage is that it is absolutely necessary to break down the bulkheads.

Replacing the slab structure results in a new structure that is virtually perfect, as the old slab is demolished and a new, modern slab is made. This also has the disadvantage that dismantling and rebuilding the entire internal structure is extremely labor intensive, e.g. removal and rebuilding of partitions, electrical and other fittings.

A solution known from Hungarian Patent Application No. 190 182, which can be used to increase the load-bearing capacity of beamed timber beams, attempts to overcome the above deficiencies.

In essence, the filling of the slab structure over the wooden beams is removed and reinforced concrete slabs are replaced. The connection between the wooden beams and the reinforced concrete slab is called shear. Implemented by "spikes". The slab structure of the slab structure, also known as "wooden concrete", is made of reinforced concrete slab and its drawn belt is made of wood beams.

The design has the advantage of reinforcing the slab without dismantling the entire wood slab and at the original slab thickness.

However, it has the disadvantage that the slab has to be demolished over the entire surface of the slab and the slab has to be replaced by reinforcing reinforced concrete slab over the whole slab.

A further disadvantage is that the reinforced concrete slab over the entire timber beam is unfavorable in terms of building physics, primarily in terms of vapor diffusion, since it closes the possibility of ventilation of the timber beams and accelerates the fungus of the timber and thus its destruction.

The design requires a great deal of material and labor.

It is an object of the present invention to provide a solution which is the same but easier and quicker to replace the slab. It was also the task of preserving the advantages of the known methods of increasing load-bearing capacity, but eliminating their disadvantages.

The idea of the invention is based on the recognition that if the slab is not completely reinforced, but only by strips, and the reinforcing reinforced concrete strips are reinforced in a specific way, then the problem can be solved. Therefore, slab reinforcement can be performed in batches, demolition work is only required in the reinforcement lanes and only to a limited extent.

In accordance with the object of the present invention, the structure of the present invention is used to replace a beam containing a beam, preferably a beamed timber beam, which comprises beams on a supporting structure, generally a wall structure, optionally spaced between has reinforced concrete slabs and the reinforced concrete slats are directly or indirectly attached to the original beams - such that the reinforcing structure is preferably provided with beams joining the reinforced concrete slabs, the reinforced concrete slabs being supported by the slab supporting structure and are connected to each other by transverse drawbeams relative to their axis.

A further feature of the structure according to the invention may be that the reinforced concrete slab is supplemented with a reinforced concrete slab made with it.

A further feature may be that the original beams are attached to the cantilever beams and / or suspended from the drawer beams.

The present invention has technical advantages as well as economic advantages over the known solutions. The primary fact is that slab structure does not change the thickness of the slab structure. to2

Another advantage is that it can be used to reinforce beamed ceilings of any material. This is not only the case with damaged or obsolete slabs, but also for example. reinforced concrete beamed ceilings, where due to the changed usage it is necessary to increase the load bearing capacity of the slab. In such cases, the existing beams can be made to work with slabs and thus significantly increase the load-bearing capacity of the slab.

It is also advantageous that by appropriately selecting disk tracks, you can save a significant part of the breakdown. Failure to do so will lead to a reduction in costs, lead time and labor requirements, which will be economically advantageous.

The invention is illustrated by way of exemplary embodiments, with reference to the accompanying drawings

Figure 1 is a cross-sectional view of a reinforced slab, a

Figure 3 is a sectional view taken along plane III-ΙΠ in Figure 2.

The confirmation of Figure 1 was performed as follows. From the weakened covered beamed timber slab, the load-bearing cover (1) and the filling (2) placed directly under the load were removed. Advantageously, the upper deck (3) has been removed during every second beam. The beams (4) were treated with preservative and antifungal agents.

In the strip of upper cut-out (3), the lower plank (5) is supported by the temporary posts (6). The formwork formed by the beams (4) and the lower deck (5) is provided with an insulating foil (7). Connecting elements (8) are incorporated in the side of the beam (4) to provide a force transfer connection between the reinforced concrete strip (9) and the beams (4). The recesses (15) are deepened in the supporting wall structure (12) to raise the reinforced concrete strip (9).

Subsequently, reinforcement and concreting of the reinforced concrete slab (9) was carried out. After the concrete has solidified, the filling (2) and the cover (1) have been restored to their original state and the temporary masts (6) have been removed. The reed plaster (10) under the slab remained intact throughout the workflow.

Figure 2 is a plan view of another slab, while Figure 3 is a sectional view of the same. During the reinforcement, the reinforced concrete slab (9) is completed with the head plate (11) and connected to the draw beam (14). Drawer beams (14) and beams (4) are fastened to the switching element (8). In addition to the supporting structure (12) running along the edge beam (13), the significance of the reinforcing structure according to the invention lies in its ability to adapt to a wide range of the slabs to be reinforced and the load-bearing requirements of the new slab.
