Description

The invention relates to the building materials industry, namely to the manufacture of multi-layer reinforced concrete panels with embedded heating pipes.

The purpose of the invention is to reduce the labor intensity of panel manufacturing.

FIG. Figure 1 shows a diagram of a mold with cracker; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

In the manufacture of reinforced concrete panels with convective channels, slot-forming agents are placed in the form, heating pipelines are installed, the concrete mixture of the lower inner layer is laid, a liner is placed to form a convective channel made in the form of slats, which are embedded in the concrete mixture of the lower inner layer, t vibrating, then install a protective partition and insulation and make the laying of the concrete mixture of the upper outer layer, vibrating t and heat the panel.

Form 1 is equipped with slot-type 2, supported on the bottom 3 of the form, heating pipe 4 is installed in the lower inner layer of concrete 5, in which a convective channel 6 is made, bounded by end faces 7 of the slot-forming unit 2 and two parallel rectangular strips 8. Above the convective channel 6, a protective partition 9 and a heater 10 are placed, while the protective partition 9 is supported on the slit-forming agents 2. The upper outer layer of concrete 11 is placed on the layer

in the warming agent 9 and in the lower inner layer, it is 5.

The method is carried out as follows.

After being laid in mold 1 with creamers 2 pipelines 4 for heating along the entire surface of bottom 3 of mold 1, the lower inner layer of concrete 5 is laid, which in the interval between the slots {gel 2 has a smaller thickness by convective size channel 6, then rectangular strips 8, which top are flush with the top of the slit formers 2, and pressed down 1-2 cm down into the form 1 closest to the face facets of the 7 slots of the gap 2, are installed in pairs on each side of them. layer of concrete 5, then vibrate) this layer, then the inc The middle layer of insulation 10 is applied in the form of slabs, resulting in a combination with rectangular strips 8, the cavity of the convective channel 6 is blocked from flowing, and the upper outer layer of concrete 11 is finally laid and vibrated, followed by heat treatment of the resulting workpiece.

I To obtain the best quality (4 cm concrete is used when laying the lower inner layer). When a non-rigid heater 10 of the slab is protected from the convective side of the channel 6, it is prevented from sinking by means of a preliminary installation; , for example, 7-8 mm thick asbestos-cement wiHcra. The rectangular slats 8 are made of this waste

sheet. The width of the rectangular planks exceeds the width of the convective channel by 1-2 cm (which prevents the concrete from flowing into the channel.

The application of the proposed method of manufacturing three-layer reinforced concrete panels with convective channels allows to achieve a reduction in the labor intensity of the production of panels by 10.9 people. min / m and decrease

COST at 0,224 rubles / m.
