Waterproof node structure warms up bathroom

Abstract: The utility model relates to a waterproof node structure warms up bathroom There is the water hidden danger on heating coil stream to indoor ground downstream in bathroom in the conventional waterproof node of bathroom threshold The utility model discloses in the bathroom including from bottom to top lay in proper order microlith concrete screed -coat, waterproof layer, protective layer, warm up the heat preservation, heating coil, microlith concrete screed -coat, stone material anchor coat, stone surface layer, its characterized in that the extension period number of ground heating coil sets up stone material anchor coat and threshold stone in the upper portion that the bathroom threshold was located, the lower part of extension section of ground heating coil sets up the V style of calligraphy bank of turning one's coat The utility model discloses set up the V style of calligraphy bank of turning one's coat in ground heating coil lower part, the ground heating coil of being convenient for is buckled The utility model has the advantages of simple structure and reasonable design and construction convenience and since the bathroom warm up waterproof node the construction quality defect reach the effective control for the maintenance cost reduces by a wide margin

Passive form house wall structure

Abstract: The utility model discloses a passive form house wall structure, wall body pour the building wall after the completion by reinforced concrete, the anti screed -coat that splits of coating on the wall body inner wall, outer wall body is by the anti screed -coat that splits, graphite polystyrene board, alkaline -resisting glass fiber gridding cloth, the anti -crack mortar layer, outer wall putty and outer wall decorative layer are constituteed, the anti screed -coat that splits of coating on the wall body outer wall, at the anti graphite polystyrene board who pastes by the fixed two -layer fissure of displacement of solar heat protection bridge heat preservation nail on splitting the screed -coat, fixed alkaline -resisting glass fiber gridding cloth on graphite polystyrene board, on alkaline -resisting glass fiber gridding cloth coating anti -crack mortar layer, outside coating wall putty on the anti -crack mortar layer again, the last outer wall decorative layer of fixing on outer wall putty. The utility model discloses it is thermal -insulated effectual to keep warm, and the gas tightness is strong, and graphite polystyrene board 's coefficient of heat conductivity only is 0.032 W (M. K), has effectively reduced " the invasion " of thermal loss of indoor cold and room separately cooling hot -air.

Method for manufacturing a plaster false floor.

Abstract: of EP0300135Known mould elements have a level mould board and a multiplicity of feet arranged on the underside of the mould board. With stable mould elements, there is the problem that, depending on the nature of the bare floor, not all the feet stand on the bare floor. After its completion, the false floor is then hollow at these points and is thus less able to bear loads. With other mould elements, use is made of a relatively thin foil which is filled with fluid screed. However, it is not possible to walk on the foil when pouring the screed. To overcome these disadvantages, a mould element is proposed on the underside of which three feet are attached in a triangle-like arrangement. The false floor is produced by laying a multiplicity of such mould elements, to which a screed is applied. This ensures that all the feet of the false floor stand on the bare floor. The mould elements are used in the retrospective construction of false floors, in particular for floor installations.

Method for bonding on gypsum screeds

Abstract: The adherence on a calcium sulfate-based screed with a residual humidity of more than 1% and/or after a measured duration after casting the screed, of less than 3 weeks, and/or on a waterproofed screed uses mortar adhesive with a base of water repellent calcium sulfate.

Apparatus and method for forming concrete planks or slabs

Abstract: 1,098,630. Moulding concrete. SPAN DECK Inc. Nov. 9, 1965, No. 47417/65. Heading B5A. [Also in Division E1] A concrete building element having a heat and sound insulating core is made by first laying and consolidating a layer 21 of a " dry " concrete mix on a longitudinally extending casting bed (33) Figs. 1, 2 (not shown), laying reinforcing rods (31) therein and pre-tensioned cables (30) thereover and then continuously depositing therein vermiculite from a hopper 87 and a " wet " concrete mix from a hopper 89, both hoppers being mounted on a frame 84 movable on wheels 86. A downwardly depending portion 110 of hopper 87 opens into the forward end of a core mould 88 which comprises only a front wall 106, side walls 105 and a top wall 104 which slopes downwardly rearwardly. The rearwardly disposed hopper 89 deposits the wet concrete from a shoot 117 on to the top and sides of the core mould, so that as the frame 84 moves the layer of vermiculite from the interior of the core mould is surrounded by the wet concrete. A treble cord plank (20), Figs. 13, 14 is formed by disposing three core moulds longitudinally in parallel, the vermiculite and wet concrete being distributed evenly thereto. A shoe 131 and a screed (96), Fig. 6, smooth the " wet " concrete as the frame passes the concrete being distributed evenly by a vibrator 134 carried by a pulley driven eccentrically weighted shaft. The frame 84 is removed when it has travelled the length of the bed 33, the inset plank then being cured for 12-15 hours by lowering thereover a hood (149) which is filled with steam from pipes 152. After curing the pre-tensioned cables are cut and the plank is cut into suitable lengths using a diamond saw (154), Fig. 12 (not shown). The core may be removed to give hollow planks, and " wet " concrete may be used for the base layer 21. A series of planks may then be transversely joined to form floors. In a further embodiment for making a single cored slab, Figs. 16-18 (not shown) a simplified apparatus is described in which the vermiculite and " wet " cement hoppers (217), (215) respectively are combined. In both embodiments a "dry" concrete mix comprises 820 lb. of expanded shale, 188 lb. of cement and sufficient water to bring the mix to a damp, slightly sticky but still granular consistency; a wet" mix comprises 730 1b. of # inch - # inch limestone, 730 lb. of “ inch dust expanded shale, 517 1b. of cement and sufficient water to give a 6 inch slurry. The density of the " dry " mix is about 65 1b./cu. foot, and the '' wet " 110 1b./cu. foot or more, the latter having a 28 day strength of 5000 p.s.i.
