Ten mysterious weapons inspection room had to bring!

First, Shantou

This tool is very important in the process of housing inspection. The purpose of this tool is as follows: In the acceptance of the main structure of newly-built houses, you can use the small hammer to gently tap the wall that has been initially painted and hear the voice of “empty”. The cement mortar was not evenly filled or its amount was not enough. The internal wall surface plastering layer was cracked and sanding occurred. These conditions all indicated that the housing quality was unqualified.

If you hear a dull knock, then there is no problem with quality.

Judging from the circumstances of previous house collections and inspections, empty drums usually appear on both sides of the windowsill or in the middle of the wall. For empty positions, the construction party must carry out serious rectification. If the emptying area is below 37.5px × 37.5px, the impact on owners' decoration will not be too great.

Empty drum rectification proposal: knock down the plaster layer at the empty drum, clear the grassroots, and re-level it with the same cement mortar. Clean water for 7 days to prevent it from cracking again.

Additional Note: When tapping with a hoe, you can place several newspapers on the wall to avoid leaving a trail.

Second, flashlight

The more glare the light, the better. The purpose is to survey the main structure of the house and see if the wall is straight and there is no part that is convex or concave. Use the flashlight against the bottom of the wall and look up. The part where the shadow appears is the problem area. And so on, all the walls can understand the basic situation. At the same time, you can also check whether there is construction waste in the flue and vent.

For uneven areas on the walls, the owners can re-smooth themselves with putty during the renovation. However, in order to avoid any omissions, we must use a flashlight to carefully check whether there is a running phenomenon in the inspection. Although there are few problems in running the wall, if we can't detect the wall running in the inspection In the case of renovation, more materials and labor will be consumed for re-decorating the walls.

Wall running correction suggestions: If the running part of the wall deviation is not large, you can use an angle grinder to smooth the formation. For walls with large deviations, they should be leveled by hand and then smoothed with cement mortar.

Supplementary note: The best choice for emergency flashlight flashlight, not only has a strong light, but the light is not easy to diverge.

Third, lighter

In the inspection of the house, there are usually reserved holes in the exhaust passage of the kitchen and bathroom. By using a lighter, it is possible to detect whether the exhaust passage is normal. The method of use is to use fire to ignite the paper to smoke and place it about ten centimeters below the mouth of the flue to see if the smoke rises to the mouth of the flue and it is immediately bent and sucked away. If so, then there is no problem with the exhaust passage.

From the current construction process, there is usually no problem with the vent, but in order to avoid blocking problems, it should be tested. Once a problem is found, the constructor must be promptly asked to carry out repairs.

Additional Note: When using the fire test pipeline, everyone avoids burns when lit the paper. You can light a cigarette and put it on the vent to see if the smoke can be sucked away.

Fourth, tape measure

It has a great role in the inspection of the house and can be used to measure the top beam, window frames, bathroom height difference, floor height and house area. When measuring the top beam and window frame, the height of both ends should be measured separately from the ceiling. If the error is within 12.5px, it is within the reasonable range of the building, but if it exceeds 12.5px, the construction part should be required to flatten the excess part to facilitate the decoration. When putty. The height difference between the bathroom and the living room floor should be about 50px. The error cannot be too large, otherwise it will bring some inconvenience to the decoration.

Measuring the area of ​​a house using a tape measure is the most complicated. There are many owners who want to control the area of ​​their own homes when they are collecting their houses. This must be based on the floor plans in the annex to the contract. This floor plan must also have specific dimensions. For example, if the width between the living rooms is 4m, then the owner can measure the part of the living room that corresponds to the size of the house icon. The measurement data should also include half the thickness and the plaster layer on both sides of the wall. thickness. The general wall thickness is 600px or 750px, and the thickness of the plaster layer is about 100px.

Remarks: You can buy a 5 meter steel tape measure at a hardware store, and the price is around 5 yuan.
