Description

Hollow construction plates are known that are made of two sheets of asbestos cement or other material and make it possible to obtain a carrier light and fire-resistant construction of coatings and walls.

However, the well-known types of TIPS have 1 flaws, limiting the area of their application and the fact that the cavity of the plates consists of several compartments, which makes it difficult for the heaters to be laid inside the plates, and the structural fins of the plates constitute a cold freeze through designs. The interface of such plates is FLAT: the edges require a careful fit and do not ensure the joint work of the plates in the coating.

The floor slab according to the described invention is free from the listed drawbacks and allows the radio channel to solve the construction of a prefabricated warm fencing of a building, mainly of an industrial type. The main distinguishing feature of:) that plate is that it is made of two sheets of the same profile, each sheet on one side undulating

is bent and attached by the edge of the bent part to the edge of the flat part of another sheet so that between the sheets of the ol sheet there is a cavity for the insulation, and the edges form the shelves intended to match the overlap with the adjacent plates.

FIG. 1 shows a general view of a 1-layered plate in a perspective view; in fig. 2 - matching of yes and p.chit in the construction of the coating in transverse cross section; in fig. 3 is a profile of a slab serving as a cover device without a rolled carpet; in fig. 4 - a cut on such a coating; pas F1 and 5 - the butt end of the slabs pas across the farm; on fnp 6 - floor beam dh device flooring significant span (cross section); on f11g. 7 - the same beam, with insulation in the lower part of the cavity; in fig. 8- plate with a cavity divided by horizontal diaphragms into several air spaces (chambers) in cross section; in fig. 9 - end part of the same plate in longitudinal section; in fig. 10 - multi-chamber plate with diaphragms, the edges of which are fixed in the shelves between the edges of the outer sheets of the plate (cross section).

The basement plate (Fig. 1) is made of two sheets 5 / and 2, nzroTOBjicifHbix nz asbestos cement or other material. Each HMCirr sheet is flat and has a well-groomed long-edge. At the point of transition from the flat part to the dead end, there is a landing), the depth of which corresponds to the depth of the sheet. Sheets / and 2 are inverted n (1O () and,; i-grovan 11 Omk with edges r, different sides and are firmly connected. Between each tofnjH.) Thus, it turns out n;:; 1 t with a cavity, 1 meyuii and thick shelves and 5, on the side, in the plane of the liepxHe sheet, with e;

bottom sheet. The cavity of the ichitum is filled with light utenlitel 6, for example, m1I1ralnaya wool, asbestos waste, etc. The ends of the plate provide: -l: diasrhamms 7 of Cello asbestos cement or other material. .1 GMY closed, the cavity of the p.; Gits and at the same time serve to ensure the stability of the cross section of the glitas on the supports. For the rigidity of the rigidity of the fine-grained structure of the phragm. P can be installed, the cavity of the cavity in the span.

In order to reinforce the hollow plate, it is possible to use wavyly curved elements laid in its nolostn as part of asbestos cement or similar sheet material. Ycislntel; you .e elements can be of two types: a) short, installed on the plate at known distances from each other; b) the entire length of the slab, with the longitudinal direction of the waves.

The indicia are secured in the cavity of the slab with cement glue or other means.

When laying on the girders (or on the upper trusses on the farms themselves), the plates fit between the longitudinal sides of the overlap between themselves so that the upper and lower shelves of each plate enter the 5 landing plates of adjacent plates (Fig. 2). Such a mating of the plates in the construction of the fence gives the following effect: a) as a result of the wide overlap, the need for machining and fitting the faces is eliminated; b) due to the support of each item on adjacent two levels

they work together in a construction without the risk of interruptions between the individual sheets of the slab; c) a tortuous, elongated junction between the fences of the fence protects against blowing and freezing at the junction; d) the surfaces of both the roof and the ceiling are flat.

The roll of the roof is glued on the slabs without leveling the device: 11, it is sheathed. With a slope of not less than 25–30 ° and a njn-iT y1-parallel frame, the coating may be arranged parallel to the skirt without a roll coil. For: this purpose is served by 1; 1 duplicated co-operation (fng. 3), in which the section height is from side 1; the upper shelf is no longer on the thickness of this shelf than the height on the lower shelf side, and the top sheet is made without upset and is waterproof composition; the upper shelf can be given an increased width. With this modification, the Htn-i plates are laid over the overlap slope so that the water flow is reliably ensured (Fig. 4). Oprani plates on the top of the farm can in this case be carried out, as shown in the fng. 5. The gap between the ends of the plates is compacted with mineral wool padding or laying of a harness. The slabs are secured with a bar that is installed on the bitumen with bolts, and an asbestos-cement ridge is placed on top of the bar.

When the device is made of the described plates, the warm wall enclosures of the plate are installed horizontal and roll to the vertical elements of the frame. Due to the deep overlap, the seams are reliably protected from leakage. The outer sheets of the slabs can be painted and painted to obtain the color etching of the facade of the building. Both in the coatings and in the walls, the longitudinal seams between the slabs can be compacted with bundles or pads, for example, from bituminized cardboard, mineral wool, etc., or filled with mastic, mortar or other plastic mass.

When arranging coatings of significant spans (up to 6 g), the cross section of the plates should be developed in height

and the slabs are in the form of hollow beams. In such beams, it is necessary to give the S-shaped side walls, forming a rounded groove and a comb, which makes it possible to obtain a mutual conjugation of the beams nestled “into gpunta {fig. 6).

At such a junction with local load on one beam, the elements of the cover are drawn on both sides of it, which is especially significant for large spans.

In hollow beams, having a significant sectional height, there is no need to fill the entire cavity with insulation. To fix the thermally insulating material in the lower part of the cavity, a sheet of abestocement or other similar material is laid in the beam, forming a fixed horizontal diaphragm (Fig. 7).

In both slabs and beams, the required thermal resistance can be achieved, in addition to thermal insulation filling, with a device in the cavity of a series of closed air spaces or chambers. To this end, sheets of asbestos cement or other low-permeable material that are firmly abutted against the side and end walls (Fig. 8 and 9) can be fixed inside the slab or beam. To achieve a more reliable breakdown of the air chambers, it is proposed to use profiled sheets, the edges of which are fixed in the shelves between the edges of the outer plates of the plate (Fig. 10).

The technical and economic effect from the application of the above-described building boards in the coatings of industrial buildings consists mainly in the following: 1) low weight of the coating (60-70 kg / m), saving

steel in bearing metal structures; 2) the ability to overlap larger spans than known types of prefabricated fire resistant structures allow; 3) the simplicity and industrialism of the manufacture of plates with the possibility of varying over a wide range of their thermal resistance; 4) the simplicity of the motivation of the coating, the possibility of its implementation in a short time and without seasonal restrictions.
