Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the enlarged diagram of masonry block;
Be labeled as in figure: 1-builds layer, 11-masonry block, 111-prefabricated section, 112-heat insulation, 113-fixed support, 12-separation layer, 13-expanding layer, 14-louvre by laying bricks or stones.
Detailed description of the invention
For the ease of understanding the utility model, below in conjunction with accompanying drawing, the utility model is further detailed.
As shown in Figure 1, the utility model drying grate insulated wall, original layer of building by laying bricks or stones is improved, layer 1 of building by laying bricks or stones after improvement is made up of multiple masonry block 11 laid out in parallel, multilayer is built layer 1 by laying bricks or stones and is laid in successively outward the inwall of funnel body from interior, building layer 1 by laying bricks or stones is at least two-layer, this arrange be in order to prevent ground floor build by laying bricks or stones layer 1 by unexpected being burnt after total collapse; Adjacent building by laying bricks or stones between layer 1 is provided with separation layer 12, increases integrally-built intensity; As shown in Figure 2, described masonry block 11 is built by laying bricks or stones by heat insulation 112 and prefabricated section 111 and is formed, and prefabricated section 111, in inverted " L " shape, is fastened on heat insulation 112.
Relatively firm in order to make to build by laying bricks or stones between masonry block 11 neighbouring when layer 1 is paved with on funnel body inwall, make neighbouring masonry block 11 Heterogeneous Permutation.
Because drying grate insulated wall works in hot environment, because being heated, masonry block 11 can produce expansion, increase expanding layer 13 between upper and lower masonry block 11, the material selection polyethylene PV plate of expanding layer 13, avoid mutually extruding the stability that impression builds layer 1 by laying bricks or stones because of expansion between masonry block 11.
As preferred version of the present utility model, high-strength corundum fireproof brick selected by prefabricated section 111.
Concrete, described heat insulation 112 is formed by from interior anchoring brick layer, asbestos layer and refractory fiber floor of building by laying bricks or stones successively outward; First weld with wall with special anchored brick fixture, adopt the continuous welding of E4303 welding rod, weld spacing 300mm, then spreads anchored brick, 300mm asbestos and 500mm refractory fibre, finally pours into a mould.
As preferred version of the present utility model, build by laying bricks or stones between layer 1 and separation layer 12 and built by laying bricks or stones by high-strength steel fibre castable; Built by laying bricks or stones by phosphate high alumina mud between heat insulation 112 and prefabricated section 111, puzzle joint is 2mm.High-strength steel fibre castable workability is good, and the presetting period is moderate, only need shake a little or just pourable shaping without the need to vibrations in construction, and wearability, iron-resistant powder aggressivity are good, have good heat-resistant knocking stability and excellent high temperature strength.
Concrete, in order to prevent ground floor build by laying bricks or stones layer 1 by unexpected being burnt after whole body of wall collapse, while also in order to improve the structural strength of body of wall, between heat insulation 112 and prefabricated section 111, fixed support 113 is vertically set; Fixed support 113 has the external part of band bending, and the tail end of described fixed support 113 is vertically fixed on separation layer 12; The upper end of described prefabricated section 111 is provided with bending groove, and the external part of fixed support 113 and the bending groove of prefabricated section 111 upper end fasten.Fixed support 113 forms fenestral fabric, plays fixation, avoids the situation causing bottom to build layer 1 entirety by laying bricks or stones loosening due to local masonry block 11 distortion to occur, thus the service life of whole drying grate insulated wall is effectively extended.
Concrete, separation layer 12 needs to be used for as fixed support 113 provides substrate, selects intensity high and the good stainless steel separator of conductivity of heat.
Concrete, be provided with multiple through louvre 14 of building layer 1 by laying bricks or stones building by laying bricks or stones on layer 1, the temperature difference of each section can be reduced, improve the quality of finished product.
