How to groove the concrete wall to save trouble, how to open the groove of the concrete wall

1.Use a cutter to cut out the outer outline of the groove along the line drawn on the wall. 2.Use a chisel to chisel out the length, width, and depth of the groove.

1) Disclosure: Before the disclosure, the owners had better prepare a list of switches, sockets, network cables, and the location and number of switches, sockets, network cables, and ** lines required for different functional areas of each room, and they can also be marked on the floor plan and brought to the site.

2) Spring line: ink cartridge, pull out the thin line, press on both sides, mention in the middle, snap, and the wiring is completed.

3) Slotting: The electric drill goes into battle, put on gloves, start drilling the groove, and groove along the line that has been bounced before.

4) Graduation photo: Eight hours later, the graduation photo of the trunking will be on the stage.

Precautions for wall slotting.

1) After clarifying the specific needs, the construction personnel should play the ink line according to the position marked by the positioning, and carry out the wall slotting treatment, and prohibit violent slotting.

2) Because the transverse slotting will destroy the load-bearing of the whole building, reduce the seismic capacity and make the wall easy to crack, so in the slotting process, it should generally be vertical and vertical slotting, and the phenomenon of transverse slotting of the wall is not allowed to be greater than 30cm.

3) When wiring in the bedroom and living room area, the trunking should be buried next to the keel under the floor to prevent too much slotting from causing cracking of the wall, but the kitchen and bathroom are absolutely not allowed to walk wires on the ground.

4) The corners of the channel should be rounded to prevent the corners from scratching the threading pipe.

5) In order to avoid uneven wall surface after scraping putty after sealing, or the wall paint cracking caused by too long prevention and control time and too shallow sealing groove, the depth of wall slotting of the embedded diameter of the line pipe should not be less than 3cm.

6) When the solid wall is slotted, in order to reduce the damage to the safety of the wall structure caused by the slotting, a special slotting machine must be used. The width of the groove should be about 10mm larger than the outer diameter of the pipe, and the depth of the groove should not be less than the outer diameter of the pipe plus 15mm, and the length of the horizontal groove of the wall should not be greater than 80cm.

1. Before slotting, you can soak the parts that need to be slotted with water, so that drilling with a drill bit will save a lot of effort. Moreover, the decoration master said that one of the advantages of using a drill bit to open the socket socket box is to be able to accurately open the position of the socket cassette, and it is much more convenient to seal it if you don't want to do the socket later.

2. At the same time, for the slotting on the TV background wall, a similar method is also adopted, first use a hammer and a drill bit on the wall to make a vertical outline, and then slowly open it with an electric drill, which is simple and trouble-free, as shown in the figure below.

3、After the wall groove is laid, you can bury the wire guard pipe prepared in advance,The reason why you need to use a wire guard pipe,The advantage is that it can not only play a certain role in protecting the line behind the TV,And the threading and later maintenance will be much more convenient。

1) Try not to groove horizontally on the load-bearing wall:

From the perspective of the overall structure and seismic resistance of the house, slotting on the load-bearing wall and beams and columns, the slotted wall is not a whole, but is cut into two or even more parts, which will definitely have a certain impact on the safety of the wall and even the entire house. Try not to make transverse grooves on the load-bearing wall, which will damage the wall, not only destroy the wall structure, but also bury potential safety hazards!

2) Pay attention to the thickness and depth of transverse slotting

The horizontal slotting of the wall should pay attention to the thickness, the general principle does not allow the transverse slotting of the wall, and if it must be done, it must be paid attention to before slotting, and consider whether it is necessary. The wall slotting must be parallel and perpendicular according to the requirements, and the pipeline that must be flat from the ground is controlled at a height of 60-90 cm and a depth of 4 cm.

3) The depth of the groove should be consistent and the groove line should be straight

The depth of the wall slotting should be consistent, the groove line should be straight, and the control line should be popped out on the wall first, and then the wall should be cut with a marble machine and manually slotted. When the line is installed, the line must be guarded with a casing, the casing connection should be tight and smooth, the inside of the corner should be cut at the right-angle corner, and the arc-shaped interface should be cut on one side of the incision, and then bent for installation. After the installation of the waterway pipes, seal all the trunking of the bathroom with cement and sand mixture.

After the trunking and floor filling slag are dry, clean the ground and wall again, and the wall and floor can be waterproofed when the water is dry, and the wall waterproofing can be done one meter high. If there is a furniture wall behind the kitchen and bathroom wall, it must be made all over the wall.

Use a cutting machine and an electric hammer to open the trunking. This process requires workers to be proficient in the use of the cutting machine, so that they can cut in strict accordance with the line, and they must also be careful and careful to prevent damage to other walls.

The wall is slotted deep, the concrete wall has a 2-3cm cement mortar protective layer, and the steel bar has a protective layer in the wall, so it can be opened to at least 4cm, even if it touches the steel bar, but the back of the steel bar is also concrete, so the steel bar can be bypassed. All kinds of line pipe grooves should be advocated to be slotted by the cutting machine, so that they are horizontal and vertical.

Workers are required to ensure that the wire is as deep as possible when slotting, and it is required to lay steel wire mesh outside when it encounters the place where the steel bar cannot be deep, so as to avoid cracking of the paint in the future. The intersection of the conduit of the specification should be grooved in the ground or used as a bridge. If the tubing passes under the keel, it should not simply be raised up, but should be grooved on the back of the keel so that the tubing can pass through and catch the tubing.

It is strictly forbidden to groove on the load-bearing wall:

When some construction teams carry out hydropower renovation construction, they directly groove and lay line pipes on the load-bearing wall, which may affect the load-bearing structure of the house, and there are greater safety hazards. Key details: If you need to route the line on the load-bearing wall, you can use an insulated yellow wax pipe instead of a PVC pipe, because the yellow wax pipe is relatively thin, as long as the cement layer on the load-bearing wall is chiseled, it can be buried.

Generally, the wall surface should be avoided as much as possible to avoid transverse slotting

Laying water pipes and wires requires slotting in the wall, but it must also be implemented in accordance with the specifications, otherwise there will be potential safety hazards. For example, when some workers lay the wires in some rooms, they directly groove the wall horizontally, and the length is very large. Generally, the span of the transverse slotting on the wall should not be too large, because the transverse slotting can easily cause the plastering layer of the wall to sink due to gravity, resulting in cracks in the future.

It is understood that although the transverse groove on the light wall does not affect the structure of the overall house, considering that this has an impact on the structure of the light wall itself, even if it is a light wall, most brand companies are not allowed to open the transverse groove.

Use a cutter to cut out the outer outline of the groove along the line drawn on the wall.

2.Use a chisel to chisel out the length, width, and depth of the groove.

Concrete wall grooving machine.

Concrete wall slotting machine is a practical power tool, mainly used for water and electricity installation and other processes for concrete, old fire, granite, ordinary brick walls, etc. wall slotting work, generally composed of the main engine and auxiliary machine, the host is mainly responsible for wall slotting work. The auxiliary machine is a special vacuum cleaner used to absorb dust. The main machine consists of a fuselage, motor, shell, gear, switch, bracket, knife cover, output shaft, handle, blade, etc.

As we all know, the traditional wall grooving, to cut out the line seam first and then chisel out the wire groove with an electric hammer, this method is not only complex to operate, low efficiency, labor-consuming and time-consuming, not to mention the damage to the wall. The concrete wall slotting machine can open the construction groove at one operation, the speed is fast, the line is not needed and then use other auxiliary tools, a molding, is the old house bright line to dark line, new house decoration, ** line, network cable, cable TV, water and electricity lines and other ideal slotting tools.

Good advanced slotting machine, brick concrete wall can be done in minutes, and the plumber is blessed.

Wall grooving machine, the tool that electricians and decorators dream of.

In general, it is hammered out with a chisel and a hammer. There are too few professional slotting machines, after all, the cost is put there.

It is best to find a professional master to do it, and you should know the line position in the wall before slotting the wall.
