What is the method used to punch holes outdoors to the designated position indoors?

Reinforced concrete walls can generally open less than 200 holes, and the hole opening tool is generally using rhinestones. It is impossible to hit concrete with an ordinary drill bit, and the drill bit can be annealed and smoothed with one eye, and it is not particularly easy to use with a cement drill bit, and it has to have an impact function.

There are several ways to fix the shelf on the wall: the narrower one can be nailed to the wall with wooden strips (the general red brick wall can be directly nailed into the cement steel nail, if it is a concrete wall, it is necessary to punch the hole with an electric hammer and then use a wooden wedge to hammer into the hole and then nail the wooden strips) The next is to fix the shelf on the wooden strips, and then use other wooden boards to flatten the wooden strips on the reverse side, and then nail the veneer and brush the paint OK.

When satellite positioning cannot be used in the indoor environment, indoor positioning technology is used as an auxiliary positioning of satellite positioning to solve the problem that the satellite signal is weak and cannot penetrate the building when it reaches the ground. The final location of the object is currently located.

There is no particularly good way, that is, through measurement positioning, the focus of measurement is to select the reference point, in order to improve the accuracy, at least two reference points should be selected, the starting point of the reference point should be the common position of the inner wall and the outer wall, even if the starting position can not be determined at the same time, the starting position should be determined by measurement, such as the window edge or the door frame edge, the corner edge of the wall, etc. FYI.

You can't punch holes indoors, but if you need to decorate the house, you can punch holes, and it doesn't have any effect.

To decorate the house, the main directions need to be punched in the following directions:

1. Punch holes for smoke exhaust outlets.

When punching holes for the smoke exhaust outlet, it is best to pay attention to the flue hole to be regular, so as to avoid inconvenience when installing the pipe. When the flue hole is opened, the lower edge should not be on the top of the wall cabinet, otherwise the gap in the wall cabinet may cause smoke to escape, resulting in the aftertaste of the flue. It is best not to block the flue hole by the gas pipe, which can prevent it from being squeezed when installing the flue.

2. Cabinet installation punching.

The most important point is to figure out the direction of the wires and water pipes in the wall when punching holes, so as to avoid breaking the wires and water pipes in the wall.

3. Punching lamps and lanterns.

When decorating, many owners will choose "water pipe to the top", so when punching holes for the lamp on the top of the living room, you should pay attention not to break the water pipe; At the same time, it is necessary to avoid cement cavities at the top, so as not to affect the quality of the house.

4. Air conditioning installation punching.

It is necessary to purchase an air conditioner in advance before punching the hole. Then, according to the shape of the indoor air conditioner and the position you want to hang, you can make a hole. Then wait until the wall is almost finished before installing, so that it will not cause damage to the wall.

Precautions for interior decoration punching.

1. When punching holes in the interior decoration, it is necessary to pay attention to the different size of the holes in each room, and the problems encountered are also different, such as the installation position of the range hood when punching, in line with the installation size of the range hood, too high or too low will affect the effect.

2. When installing the bathroom, it is necessary to budget the location of the furniture and arrange the space reasonably. For example, the location of the shower, the location of the water heater, especially when the water heater is installed, we must pay attention to the space for water supply and discharge, and reserve enough space for rent. Otherwise, it will be more troublesome when installing the water and sewage pipes.

3. There are many places that need to be punched in the interior decoration, and we all go to punch holes after pasting the wallpaper, so we must plan the location before punching, and there is no way to fill the wrong hole, which will affect the overall effect of home decoration.
