Method to reinforce structures of building cover

FIELD: construction.

SUBSTANCE: method to reinforce structures of a building cover, comprising bearing structures, runs and an enclosure, consists in installation of reinforcement beams from channels resting against bearing structures between existing runs. In the areas of resting of reinforcement beams onto bearing structures they cut a section of an upper shelf of a channel, using welding, they fix a similar section at the opposite side, turning cross sections of the channel into a z-shaped one. Final installation of reinforcement beams is carried out by means of their rotation around the longitudinal axis.

The invention relates to the field of construction, and in particular to methods of reinforcement of structures with lightweight roofs of buildings.

There is a method of amplification of structural coverage, including supporting structures and fencing in the form of ribbed slabs (Malygin, A.I., Spitting B.C. the Restoration and strengthening of the enclosing structures of buildings and constructions. Tomsk. "Print factory", 2002, str). Strengthening of structural coverage is to install reinforcing beams with the upper zone of rolled I-beams.

The disadvantage of this method of amplification is the complexity of the installation of all reinforcing trussed beams in the cavity between the bearing structure and reinforced cladding and the need to use podklinivaja elements.

There is a method of amplification of structural coverage, including supporting structures, beams, flooring and decking (KTN. I.S. Rebrov. Strengthening the core metal structures. M.: stroiizdat, 1988. p.12-13). The reinforcement beams and flooring is accomplished by the supply of additional beams I-beam section.

The disadvantage of this method of amplification is the complexity of deciding reinforcing beams and transmitting the load from the deck to additional I-beams.

Closest to the invention is a method of strengthening structures p is the closure of the building, including supporting structures, runs and fencing, consisting in the installation between existing purlin reinforcing beams of channel, based on the supporting structure and attached the ends to the adjacent purlins (RF patent No. 2199636. IPC E04B 5/10. Bulletin No. 6 dated 27.02.2003).

The disadvantage of this method of amplification is the complexity of the installation of reinforcing beams of channel in the opening between the bearing and enclosing structures of coverage and getting them to work together.

The invention is directed to reducing the labor required for the installation of reinforcing beams and reliability enable load-bearing and enclosing structures in the joint operation.

The result is achieved that in the known method of strengthening the roof structures of buildings, including structures, runs and fencing, consisting in the installation between existing purlin reinforcing beams of channel leaning on their supporting structures, according to the invention before installation of the reinforcing beams in places bearing on their supporting structures cut out portion of the upper shelf sections and the welding of the fixed similar plot shelves on the opposite side of the wall, turning the cross section of the channel in the z-shaped, and the final installation of reinforcing beams is carried out by its rotation around the longitudinal axis.

On Phosa constructive slit coating.

Figure 2 shows the process of transformation of the area channel section reinforcing beams in the z-shaped cross-section. Dashed lines indicate the cut section of the shelf.

Figure 3 shows the final installation of reinforcing beams by its rotation around the longitudinal axis.

Method of strengthening the roof structures of buildings, including supporting structures 1, runs 2 and enclosure 3 is installed between the existing purlin 2 reinforcing beams of channel 4, based on the supporting structure 1. In reinforcing beams 4 before you install them in places bearing on the supporting structures 1 cut out portion of the upper shelves and the welding of the fixed similar plot shelves on the opposite side of the wall, turning the cross section of the channel in the z-shaped (Figure 2). Next, the reinforcing beam 4 is slid into the cavity between the bearing structure 1 and enclosure 3 and by its rotation around the longitudinal axis mounted in operating position between the bearing 1 and enclosing 3 designs. When turning the reinforcing beam 4 in the area of its bearing on the supporting structures 1 overall height z-shaped section is not changed and is equal to the height of the cross section of the existing 2 runs. Therefore, is provided with a contact bearing 1 bearing 3 structures, i.e. their inclusion in the joint operation.
