Description

The invention relates to the invention, in particular to the lamination of industrial buildings. '

Known lantern cover industrial buildings with anti-aircraft lanterns. Antiaircraft lights provide us- ⁵

natural light conditions [1].

However, the use of zenith flashlights is limited, as they do not provide for the natural aeration of buildings. In addition, such lights are impractical in buildings where, under the conditions of the technological process, direct sunlight is not allowed.

Closest to the proposed solution is a coating with a U-shaped svetoeratsionnymi lanterns [2].

However, the construction of such lamps requires a significant increase in the steel consumption per device of superstructure lanterns, and the number of types of mounted elements increases. For example ’except rafters

structures and reinforced concrete slabs fences, lamppost panels, lampposts and connections between them are added.

The purpose of the invention is to reduce the costs. Yes, they became with the increase of industrial- ity due to the reduction of the nomenclature of prefabricated elements.

This goal is achieved by the fact that in the coating of a building with a U-shaped lantern including roof trusses reinforced concrete ribbed plates supported on them, the lantern carrying elements and the glazing of the lantern, the lantern bearing elements are made of coating plates installed in the middle of the truss with the formation of ( a lamppost, with the light openings with glazing between the edges of the installed plates, and the lantern frame rigidly integrated with the roof trusses. '.

FIG. 1 shows a lantern with a width of 6 m with vertical glazing; on

FIG. 2 - a lantern with inclined glazing or any significant

with a width of about m below, and 3 m above, in FIG. 3 - a lantern with inclined glazing with a width at the bottom of 9 m, and at the top 6 m.

The coating includes truss truss 1, reinforced concrete ribbed plates 2, bearing elements of the flashlight 3, steel braces 4, and sash 5 glazing. FIG. 3 shows a variant of the coating, where, in addition to plates 3 m wide, there are additional plates 1.5 m wide laid on the upper farm belt at the edge of the lantern. In this case, to prevent local bending of the upper truss belt, additional rods are arranged in it (shown by dotted lines).

The need for a device such a lamp is dictated by the desire to improve its lighting qualities. In addition, increasing the width of the lamp provides the best use of it for unloading trusses. At the same time, the variant of coating on ₂₅ fig. 3 is one of the possible.

... The peculiarity of the constructive solution is that the carrier elements of the lantern 3 are made of ribbed plates, the same as ^ plate 2, in which the shelf is removed within the height of the light opening between the ribs, and the remaining part of the shelf serves as an onboard fence lantern. Concrete ribbed plate width of 3 m (3x6 or 3x12 m) Collateral ³⁵ Chiva typical single-stage apparatus glazing lamp 1.75 m height 1,464-11 series matching at normal altitude airborne ograzhu * Denia, Compound ⁴⁰ between the lamp elements are made to weld through eavesdropping details by known methods.

The proposed solution in comparison with the known can significantly reduce the consumption of steel ⁴⁵ . This is achieved through the implementation of the supporting elements of the lantern of reinforced concrete ribbed plates.

Besides saving steel execution 'lamp ⁵⁰ elements of reinforced concrete ribbed plates can reduce the number of types of prefabricated elements lantern ^ improving these industrial coatings in general. Concerning; 55 remove part of the shelves in the plates for the pass, the light flux, then this fact does not contribute Zaurud · *

changes in platemaking technology.

In the proposed solution, the need to arrange connections between the upper belts of the trusses under the headlamp can be eliminated. This is ensured by the fact that the rigidity and durability of reinforced concrete ribbed plates allows the entire construction of the lamp superstructure to be incorporated into the joint work with roof trusses. In this case, the compressive forces are transmitted to the lamppost elements, and the braces 4 work in tension. According to the data of numerical analysis, with a total unloading of the bottom part of roof trusses, the compressive forces in the upper belt can be reduced to three times, which is sufficient to eliminate the need for arranging connections between the upper trusses of the trusses.

The inclusion of the construction of a lamp superstructure in collaboration with roof trusses is especially advisable in precast-monolithic coatings, where reinforced concrete slabs located on roof trusses are combined with the upper belt to work together with it in compression.

In this case, the maximum reduction of the material consumption of the lamp cover is ensured. Thus, the inclusion of a lamp-house superstructure in collaboration with truss trusses reduces the material consumption of these farms and eliminates the need for arranging connections between them.

The proposed solution allows to reduce the consumption of steel in lantern covers with U-shaped lanterns up to £ 25 with a decrease in the number of types of precast elements. It should be noted that while saving steel in the coating, there may be an increase in the consumption of concrete up to 5 "7%, for example, with the vertical position of the lantern panels (Fig. 1).
