Tell me how to adjust the cracks in the wooden door.

The owner, Mr. Shan, has been very confused recently. The new wooden door at home just made him feel that the sound insulation effect was not as good as before. You can clearly hear the voices in the living room in the bedroom. After careful observation, he found that the crack of the door seemed a little big. He thought about it carefully, and the sample doors on the market all fit. My door will not fail, will it? At present, the sound insulation performance is not a rigid index of the living room wooden door, but there are indeed many quality factors, and consumers can't ignore this link.

The crack of the door has a standard size.

As for the statement that the sample doors reflected by Mr. Shan are all put together, the wooden door samples displayed in the store are really put together, otherwise they will hardly notice that there are big gaps in these wooden doors. But the door of Mr. Shan's house "seems a little big". Does this meet the requirements?

Regarding the number of seams left, there are relevant requirements in the wooden door industry standard. Generally speaking, the gap between the door and the ground must be 5-8 mm, the gap between the left and right sides of the door and the door frame should not exceed 6 mm, and the top seam of the door should not exceed 2 mm. If the gap is too large, it will not only affect the appearance, but also affect the sound insulation effect, and the air inlet will not keep warm in winter; Of course, if the gap is too small, the wooden door will shrink and expand, and it will be deformed when it is wet in summer, which will lead to bad opening and closing. Mr. Shan can take his own scale to measure the size of the crack and see if it is in compliance.

Non-rigidity index of sound insulation

As for the sound insulation effect of wooden doors, there is no hard index about sound insulation in the current wooden door industry standard, unless it is a special sound insulation door. Generally speaking, consumers can achieve the sound insulation effect required by normal room life as long as they buy qualified wooden door products with medium and high prices and install them in a standardized way.

In addition, the sound insulation performance of wooden doors is also related to the material. Generally speaking, the higher the material density, the stronger the sound insulation performance. If the dragon skeleton inside the wooden door is loose and the two door panels on the surface are thin, then the sound insulation performance of this wooden door is poor. In addition, the sealing strip of the wooden door is not tightly attached, and the upper and lower seams of the door are too large, which will also affect the sound insulation performance of the wooden door.

The sound transmission in the living room is very complicated and the sound insulation is not good, which is not only related to the wooden door. Whether the wall, ceiling and floor materials of Mr. Shan's house have been moved may affect the spread of sound indoors, so Mr. Shan should make a comprehensive judgment and not simply "convict" the wooden door.

The installation level is very important.

After all, wooden doors are customized products, and their overall quality is closely related to installation. If it is improperly installed, the gap of the wooden door is too large, which has a great influence on the sound insulation effect. Mr. Shan can check the cracks in the door himself: first, see if the crack size is in compliance; Secondly, close the door and check whether the seams on the door are balanced and whether there is a situation where one side is wide and the other side is narrow. If it is not balanced, it means that the door frame is not straight and affects the appearance; If there is a gap between the door cover line and the wall surface, it is likely that the wall surface is not vertical or uneven in thickness. You can contact the workers to handle it and seal it with sealant.

But not all gaps have to be tightly filled. For example, when installing, the gap between the door cover and the wall does not need to be filled with foam glue. Styrofoam has elasticity and plasticity. If you play it too tightly, the door cover will be pushed out into an arc and won't close the door. When gluing, only the imaginary part and the real part can be used, and generally a gap of 5 cm is needed to facilitate the longitudinal expansion and ventilation curing of foam glue.

In the process of use, consumers should also pay attention to the maintenance and use of the door. When it is dry in winter, use a humidifier indoors, or wipe the wooden door with a wringing wet cloth every day to relieve dryness; Try to keep the door open before and after heating, so as to ventilate the room and reduce the influence of drying shrinkage on the door. Consumers can also push back and forth by hand to check whether there is a gap between the lock and the door. If so, they can use their own tools to tighten or contact the manufacturer for handling, which is beneficial to the use of the door. In addition, a qualified door must stop no matter where it is pushed. If it is an automatic switch, it means that the door is skewed during installation or use, and you can contact the manufacturer for adjustment.
