Detailed Description
The present invention is further illustrated by the following figures and specific examples, which are to be understood as illustrative only and not as limiting the scope of the invention, which is to be given the full breadth of the appended claims and any and all equivalent modifications thereof which may occur to those skilled in the art upon reading the present specification.
As shown in figure 1, the graphite molding polyphenyl board heat preservation and sound insulation structure suitable for the water room is laid from bottom to top in sequence and comprises: the cast-in-place concrete slab comprises a cast-in-place concrete slab base layer 1, a graphite polyphenyl board 2, a fine aggregate concrete protective layer 4, a polyurethane waterproof coating layer 5, a cement mortar bonding layer 6 and a decorative surface layer 7. The multilayer arrangement makes ground density bigger, and the performance of heat preservation and sound insulation is stronger, more prevents the condition such as leaking and takes place.
Vertical sound insulation sheets 8 are inserted between the graphite polystyrene board 2 and the polyurethane waterproof coating layer 5 and the wall body 10 and inserted into gaps, so that a sound insulation effect can be further achieved. The vertical sound insulation sheet 8 is higher than the fine aggregate concrete protective layer 4 and is continuously distributed on all wall surfaces at the wall foot in the room. The sound is isolated from the ground as far as possible by being higher than the fine aggregate concrete protective layer 4, and the sound is prevented from entering the room. The corrugated surface of the graphite polystyrene board 2 is paved downwards, and the width between board gaps is less than 2 mm. The smaller the width, the more conformable.
And cleaning the ground base layer to be flat and no scale, no protrusion or recess, removing the wall feet, keeping no dirt attached, and laying the cast-in-place concrete slab base layer 1. Therefore, no sundries are accumulated in the ground layer, and the heat insulation and sound insulation effects of the ground are not influenced.
The fine aggregate concrete protective layer 4 is provided with multilayer steel wire net piece 3 by top position, uses the ligature of thin iron wire when the overlap joint, and the overlap joint width is greater than 100 mm. Leaving space for fastening the steel wire mesh 3. The iron wires of the multiple layers of steel wire mesh sheets 3 at the overlapped position are fixed at the foremost end of the upper layer, two grids and three grids are used as fixing points, the iron wire heads are wound and flattened after the steel wire mesh sheets are tied, and the tying length is 15-25 cm, which is the length most suitable for tying wires. And the iron wire is divided into two parts, and the two parts are folded and bound when being fixed, and the iron wire head is parallel to the net piece when being bound. The problem that the ground is subjected to a series of cracks due to the fact that the organic heat-preservation sound-insulation material graphite polyphenyl plate 2 and the waterproof sealant 9 are punctured by iron wire heads is solved. The steel wire mesh at the expansion joint is required to be disconnected by 1-2 cm. The length of the opening can enable the mesh to be better attached between the upper layer and the lower layer. The distance between the steel wire mesh sheet 3 and the top surface of the fine aggregate concrete protective layer 4 is 10 mm-20 mm. Most preferably 10mm from the top surface of the fine-grained concrete protective layer 4. And the layer is more firm in the layer near the layer separation, and the layer surface is more flat due to the support.
Before the polyurethane waterproof coating layer 5 is poured, the uneven place is smoothed by cement mortar, the position of the pipeline with the sleeve is 20mm higher than the surface of the base layer, and arcs with the convex and concave angles of 10mm are formed. The steel plate is not a right angle, so that the condition of cracking during construction can be avoided.
The thickness of the polyurethane waterproof coating layer 5 is 1mm when a layer of polyurethane waterproof coating is smeared. And (3) ensuring that the upper surface of the fine aggregate concrete protective layer 4 is smooth and dry before the polyurethane waterproof coating layer 5 is poured, basically curing the first coating, and then coating a second coating, wherein the coating scraping direction is vertical to the first coating direction. The coating layer by layer can be more uniform and more fitting according to the thickness, so that the layers are more stable.
The cement mortar bonding layer 6 is arranged on the upper surface of the polyurethane waterproof coating layer 5 and the upper surface of the wall body 10, has a slope extending outwards from the wall base in the horizontal direction, has a slope of 1 percent and a thickness of 20mm, and is a compacted and smoothed 1:2.5 dry and hard cement mortar bonding layer. The design that has on both sides like this for this there is the slope on the ground that has the slope, can draw water and flow toward drainage department, thereby makes indoor subaerial water not accumulate, prevents to leak because water accumulates the long time of dwell and leads to on ground.
The finishing coat 7 is C20 fine stone concrete with the thickness of 40mm and is only poured on the cement mortar bonding layer 6. The facing layer 7 is on the slope, and separates two sides of the cement mortar bonding layer 6 to prevent cracks of the joint.
The width of the abutted seam pasted by the vertical sound insulation sheet 8 is not larger than 1mm, the vertical sound insulation sheet 8 is pasted at all lap joints with waterproof sealant 9 after being pasted, and the waterproof sealant 9 is not arc-shaped at the internal corner pasting position, so that subsequent pasting is facilitated. The vertical sound insulation sheets 8 are made of EPE pearl cotton, an adhesive layer is attached to one side of each vertical sound insulation sheet, and waterproof sealants 9 are adhered among all plate seams, the vertical sound insulation sheets and the plate seams. Not only the bonding is firmer, but also the gap is reduced.
By using the structure, the experiment is carried out in a water room, such as a toilet, and the slope end is provided with a drainage device, such as a floor drain. Comparing the standard of ceramic tile humidity, sound insulation and heat preservation when the ordinary toilet in the residential building in the south Beijing kylin Zhonghai district is not used, the data as the following table 1 are obtained:
TABLE 1
It can be seen that the embodiment can improve the effects of sound insulation and heat preservation while realizing the drainage compared with the common toilet.
