RU2504630C1 - Device for reinforcement of ceiling with wooden beams - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: device for reinforcement of ceiling with wooden beams includes metal beams along its whole length, mounted in the gaps between wooden beams. Bottom point of metal beams is located below the top of wooden beams with total inner dimension of the rest of ceiling. At metal beam top, a top rod band passing through a wooden beam and connected by supports with lower rod band is mounted, with the wooden beam resting on lower rod band over supporting plates.

EFFECT: enhanced structural capability of ceiling under reconstruction.

Description

The invention relates to the field of construction and can be used in the repair and reconstruction of buildings with wooden floors without resettlement of residents or users of the building being repaired.

A device is known for reinforcing a floor with wooden beams, (FRG application No. 3812447 from 1989 MKI E04C 3/18) containing wooden beams, a ceiling structure, metal beams and upper floor structures with transverse elements and a floor. Metal beams are made in the form of a bent profile of a U-shaped cross-section with horizontal bends installed by the shelf upwards over a wooden beam.

The disadvantage of the described technical solution is the incomplete release of wooden beams from loads, as well as the need to arrange the floor in logs, which can lead to an increase in the thickness of the floor.

As a prototype, a device has been adopted to strengthen the floor with wooden beams and reinforced floor (see RF patent No. 2120008, published 02.08.1996) including wooden beams, ceiling structure, reinforcing metal beams and the upper floor structure. Metal beams are mounted between the wooden beams. The top of the wooden beams is located above the bottom of the metal beams, the upper face of which is in the same plane with the top of the transverse elements or below the top of the transverse elements, and the total dimension "in the light" of the remaining part of the floor, the reinforcing metal beams and the new upper floor structure are chosen equal to the thickness of the existing floor . The lower shelves of metal beams are supported by the ends of a vaulted sheet curved upward, the generatrix of which is parallel to the metal beams. Monolithic concrete is laid on the vaulted sheet along its entire length, on which the floor is arranged. A wooden beam with a ceiling structure is suspended from the upper generatrix of the vaulted sheet on steel rods. The metal beam is made in the form of a bent U-shaped profile, installed with the shelf up and located above the wooden beam. The upper structures of the ceiling are supported on the horizontally bent ends of the U-beam.

The disadvantage of the prototype is the complexity of the design, the complexity of the installation, the lack of reinforcement of the beam itself.

The technical result is the strengthening of the ceiling structure.

The technical result is achieved by the fact that the device for strengthening the floor with wooden beams, contains the entire length of the metal beams that are installed in the spaces between the wooden beams, while the lower point of the metal beams is located below the top of the wooden beams with a total dimension "in the light" of the remaining part of the floor , a new top floor structure.

A feature is that on the upper part of the metal beam is installed, the upper core belt passing through the wooden beam and rigidly connected by the uprights to the lower core belt, while the wooden beam rests on the lower core belt through the base plates.

In comparison with the prototype, the proposed technical solution allows you to: strengthen wooden floors, without resorting to their complete dismantling, to work without the complete resettlement of residents or users of buildings; keep the thickness of the floor, which, in turn, saves the size of the doors and other things; the force of the beam itself is produced.

The invention is illustrated graphically.

Figure 1 shows a fragment of the overlap with a wooden beam, figure 2 is a view A.

A device for strengthening the floor with wooden beams (FIGS. 1, 2) contains metal beams 1 along the entire length, which are installed in the spaces between the wooden beams 2. The lower point of the metal beams 1 is located below the top of the wooden beams 2 with the total remaining light parts of the floor. The upper core belt 3 consists of pipes 4 and the rods passing through them 5. The upper core belt 3 goes through the wooden beam 2. The upper core belt 3 is connected by the posts 6 to the lower core belt 7. The wooden beam 2 is supported on the lower core belt 7 through the support plates 8.

Claims (1)

A device for reinforcing a floor with wooden beams, containing metal beams along the entire length that are installed in the spaces between the wooden beams, the lower point of the metal beams being located below the top of the wooden beams with a total dimension "in the light" of the remaining part of the floor, characterized in that the upper part of the metal beam has an upper core belt passing through the wooden beam and connected by struts to the lower core belt, while the wooden beam rests on the lower a core belt through support plates.
