The annual heating period is almost over, and wood products, walls, tiles and furniture-type products are partially constricted, deformed and riser skin due to low ventilation during heating, high temperature differentials and different humidity. Such phenomena as blackening of the floor, deformation of the floor, slitting of the surface of the wall, empty drums of bricks and cracking of furniture will be addressed centrally once heating has ceased。
Black spot on the floor
Last summer, when mr. Tung entered his new home and began the warm season, he found black spots on his floor, which, according to mr. Tung, were more frequent in the floor connector and the floor connector to the wall。
Reason analysis:
It's possible the floor gets darker. This is related to the fact that the floor was not completely dry before it was laid. After entering the heating season, the temperature on the ground rises, the tide evaporates faster, and the floor is drenched by leaks, which then darken the ground. This occurs mainly on the ground floors of wood complexes and on the floors of wood complexes, which rarely occur on the floors of reinforced wood complexes. This is particularly the case in families that are warm。
At the same time, because of the dry and humid nature of the wood, the wood floors and the woody composite floors are prone to deformation. Indoor temperature and humidity changes, heat swells and freezes, there are small cracks in floor connections, some of the wood floors have large cracks and even loosed out of the buttons, and others can recover themselves by spring。
Solutions:
For darkened floors, there is no particularly good treatment, but only after heating has been completed and the contact plant has been replaced。
For floor cracks, if they cannot be restored, the heating season will be completed and the plant will be contacted for repairs. The newly renovated house, after two to three years, will stabilize the floor。
The maintenance is also properly enhanced on a daily basis, with some floor wax on a regular basis。
There's a gap in the wall
Not only did black spots and cracks appear on the floor, but mr. Tung also found larger problems in the walls after winter heating, such as cracks between the walls and the top, cracks in the walls, cracks on the face and empty drums of bricks。
Reason analysis:
As the walls swell and shrink during the winter heating period, they crack, which is addressed after the heating has ended。
With the onset of the heating season, the tiles on the wall will also be empty, crack or fall, mainly because of the damage to the volume of water released, because the cement layer before the tiles is slurry, which begins to heat up, the room temperature rises, the sand under the tiles will shrink, disfigure, the tiles and the cement layer will be removed, the cement layer and the wall will be removed, and if the owners do not use the special tile coating material, such as straight sand, at the time of the renovation, the tiles and the walls will fall off if they are not properly bound together。
Solutions:
It is also very simple for the walls to be broken, with the cracks cut open, bandaged in the cracks and then scratched and painted on the surface. There are no significant problems with the patching of the wall, and if it is white, normal repairs are performed. In the case of paint repair with colour, the difficulty is compounded by the fact that there will be a difference in the colour of the wall during subsequent repair, so if the colour of the wall paint is coloured, the extra paint will be left in advance, saves the need to repaint the color difference from the double-painted paint。
The treatment of empty wall brick drums can wait until spring, when you buy yourself a bag of a special bag of straight paste sand and paste the tiles, and if your home's renovation is still under warranty, you can ask the original renovation company or the property to fix them, bearing in mind that the paste cannot be mixed with the traditional cement sand itself, so that it is difficult to match the scale, while the amount of clay in the sand reduces the hardness and viscosity of the cement, preferably using the finished straight paste. Mr. Li jian, chairman of the board of directors for the decoration of the holy places, some of the most important of which are plating techniques and techniques. Thus, in order to avoid empty walls, the first is to improve the quality of the tiles and the second is to improve technical processing capacity。
At the same time, mr. Tung also discovered the deformation and cracking of the household furniture. Deformation and fragmentation of wood furniture and redwood furniture, most of which are due to lower water content in the air, release water from relative wood species, when the wood furniture is split and there are structural changes, as we often hear in the heating season, the sound of wood change. In winter, therefore, in order to maintain the furniture, it would be preferable to regulate indoor humidity with a wetter and, after the heating period, to maintain the wood furniture and the redwood furniture with wax。
Wallback problem
After the renovation of the house was completed, and after the heating period, it would be difficult to maintain the house if there were problems with the hidden works. Upon completion of the renovation of ms. Xu's house, she found that the damage to the neighbor's heating tablet caused problems of re-alkalinity on the wall of her home。
Reason analysis:
The return of alkaline to the walls, whether new or old, carries the problem of alkalinization due to the excessive weight of water, especially in the wet environment, which is the underlying cause of the impact on the quality of paint. At this point, the owner cannot simply repair the back-up problem of his/her own wall, but first ascertains the state of his/her neighbor's heating and then fixes his/her own problems, or else repeats. In the course of the renovation, there are many opportunities for problems with hidden works, such as waterproofing, wall retrofitting and water heating。
Solutions:
The first waterproofing project, where the vast majority of construction workers are currently working for the general population, the waterproofing project has been wrong, the standard waterproofing work should be to level the wall and ground prepared for waterproofing, not to be rough on the surface, pending the drying of the cement layer and the painting of waterproofing materials. The current material should be painted three times, so that the waterproofing layer has a thickness of between 0. 5 mm and 1. 5 mm, so that it can be waterproof, so that the waterproofing layer is dry and then closed, until the waterproofing is tested, there are no leaking marks in the adjacent wall after 48 hours, to confirm that there are no leakage points before pulling up, to pull up the tiles, and to do so only if the coating of the tile is used, of course, by removing the pulling of the tiles, which can be done directly。
The second wall modification should comply with industry standards, prohibit the mixing of red bricks and cement sands, introduce light material such as gas-heated cement bricks, build more solid ash with straight-up sand mortars, which need to be maintained if cement sand is used。
The third is the retrofitting of hydropower roads, which include both up and down water, and the selection of materials of stable performance, such as ppr thermal smelting tubes or stainless steel materials. The main link after the completion of the construction is the pressure test, which many of the construction staff will press for half an hour, which is extremely wrong and should be done three times. The first was an ultra-pressure check, where the work was completed for a six-to-eight-kg test, requiring the cutting of the water table, a 24-hour portion of the retrofit, calculated on the basis of ambient temperature and atmospheric pressure, to see if there were leakage points and to ensure that there were no problems. The second pressure test was a water table, at a time when pressure was higher than the normal water supply pressure, which was less than 6 kg, because the glass on the water table was afraid of high pressure. The process consisted mainly of checking whether the modified water route was open and whether there was a problem with the hot-melting pipe blockage, i. E., the water flow was weak, so that the pipe could be blocked once confirmed. The third pressure test was a re-pressure test after all the valve taps had been installed, with the aim of checking whether the hardware valves had any quality defects and whether they had been installed with excessive force to break the hardware. The upgrading of circuits requires checking whether workers are licensed to take up jobs, i. E., technical issues, whether the power lines are produced by a regular manufacturer, and whether they meet the design requirements. It should be recalled that the kitchen and toilet, as well as air conditioners, should use 4 square wiring, check whether the fuse protection of the wires has passed off, whether construction has been regulated, etc., and, if there are more appliances in the home, choose metal-protector tubes, thus avoiding interference with signal lines.
