Light steel keel wall construction process light steel keel partition wall practice

The light steel keel partition wall has the advantages of light weight, high strength, good fire resistance, versatility, and easy installation. It has the functions of shockproof, dustproof, soundproof, sound absorbing, and constant temperature. It also has short construction period and easy construction. Not easy to deformation and other advantages. Next Xiaobian will introduce light steel keel wall partition method and light steel keel wall construction technology . Let's take a look.

What is a light steel keel wall?

I believe that for most people, it is certainly not unfamiliar to the partition. The so-called partition wall is the wall in our houses that is used to separate each room. Compared with other types of walls, the biggest difference is that he does not need to have a bearing. We found through investigation that many people nowadays choose light steel keels for partition walls. So why do so many people choose light steel keel as a wall material?

The light steel keel partition wall is a wall in the room. Although the wall has not increased the available area of ​​the house, but because there is a wall, we can carry out a split, so that the house can be more convenient for more The use of more than one person has satisfied our needs for this fast-paced society.

Why do most people choose light steel keel walls?

High safety

In fact, the main reason is because of the advantages of the light steel keel itself. Compared to other types of partition materials, the advantages of light steel keels are mainly reflected in light weight, high strength, good fire resistance, versatility, and easy installation. At the same time, for the walls with light steel keels for partition walls, there are functions of shockproof, dustproof, soundproof and constant temperature. Therefore, in a certain sense, his safety performance is very secure for houses using light steel keels.

Simple and quick

At the same time, for the construction aspect, choosing the light steel keel as the material of the partition wall has the characteristics of shortening the overall construction period, the construction method is simple, and it is not easily deformed. It is also these advantages that make many construction companies like to choose light steel keel as a wall material.

High cost performance

Compared with other types of materials, light steel keels have relatively more advantages. Therefore, both users and constructors prefer to use light steel keels as partition walls. At the same time, the price of light steel keels is more cost-effective than wood keels. More suitable as a consumer's first choice for purchase.

First, light steel keel wall selection requirements

The material specifications and model must meet the design requirements. The quality conforms to the relevant national standards and the “three certificates” is complete.

Commonly used partition wall light steel keel specifications are 75mm and 100mm, length 3m and 4m; ceiling light steel keel specifications are 50mm and 60mm, and its length is also 3m and 4m.

When selecting the light steel keel, first select the corresponding shape according to their own use. The light steel keel is divided into U-shaped, C-shaped, L-shaped, T-shaped and V-shaped according to the sectional shape. Then you must choose the qualified thickness, you can not choose less than 0.6mm products. In order to prevent galvanization on both sides of the light-gauge steel keel, the galvanized layer should be selected to be free from detachment and no tingling.

In addition, the best choice for the selection of galvanized surface snowflake clear pattern, and buried harder "snowboard" galvanized keel, this is generally the original plate galvanized keel, more difficult to rust, and greater strength .

In order to avoid the moisture, deformation, mildew and other quality problems of the partition walls, pillow bases are required at the bottom of the partition walls.

Second, the construction process

Stretching line - mounting boom - installing keel and accessories - installing plasterboard

Third, the construction process technical points

The ceiling keel installation shall meet the requirements of Section 3 of the Code for Construction and Acceptance of Building Decoration Engineering. The ceiling and equipment pipelines, lamps and fittings, and hangers shall be installed after installation.

1, first in the wall, column pop-up ceiling level ink line. Horizontal deviation allows ± 5MM or less.

2. Draw the position of the suspender on the ceiling: Do not use a diameter of 6MM for the person's suspender and a diameter of 8-10MM for the person's suspender. (When the load is too large, the cross section of the boom must be calculated.) The upper suspension rod is controlled at about 100mm from the wall. At the same time, the end of the main keel must not exceed 300 mm. Hanger thread exposed length> 3MM, end can be welded.

3, the main keel spacing is generally 1000MM-1200MM, from the wall of the first main keel distance ≤ 200MM, the main keel joints should be staggered, not on a line, the direction of the boom should be staggered, to avoid the main keel to the side dumping.

4. When the main keel is lifted, try to avoid lamps, broadcast horns, air conditioners, air conditioners, sprinklers, fire probes, etc. Sub-keel spacing is generally 400-600MM.

5. The primary and secondary keel requirements are straight and the height of the arching is not less than 1/200 of the short span of the room. For large-scale ceilings, a horizontal keel should be welded to the main keel every 12m. Light steel big keel can be welded, but it should be spot welded, sub keel can not be welded. After calibration, the keel's hanging pieces and connecting pieces are screwed and clamped.

6、Comprehensively correct the position and level of main and sub-keel; misalignment of connectors. The surface mounted keel shall have no visible curvature. The deviation of docking error of sub-keel should not exceed 2mm. When the interval between the keels is more than 800mm, the cross braces should be added between them, and the main keel should be fixed vertically with a small hanging piece.

7. After receiving the acceptance report of shelter hidden project, install gypsum board. The ceiling panels (and keels) should be arranged in order from the middle of the room to the sides. Hanging plate and keel galvanized self-tapping nail eyelid putty leveling. The joints of the ceiling panels must be installed on the secondary keel not less than 40mm. Board spacing can stay 8-10MM gap. According to the design, the color paste can be used as a surface, but it can also be used to seal the seam tightly with aluminum pressure strips or plastic pressure strips, and fixed with GB857 or GB845 cross countersunk head tapping screws (5*25.5*35).

8, balance uptake, lighting, fire probes, sprinkler heads, broadcast horns, etc. installed in the ceiling board in place.

9, when the boom and equipment fight, add a suspender and adjust the pole position.

10. Decorate suspended ceilings, first position the ink line on the ground, and then use the hanging hammer to set its exact position.

11, heavy-duty lamps, vibration fans, heavy equipment should be directly hung on the reinforced concrete floor, not connected with the keel.

Some questions about the light steel keel partition wall:

1. Compared with brick wall, its light weight, convenient construction, and does not require the advantages of structural support;

2. It is roughly divided into three parts: along the ground (into the ground through the expansion bolts), keel, card pieces;

3, the panel is generally used gypsum board, calcium silicate board; sound insulation is filled with sound insulation cotton; with the keel connected with a self-tapping screw;

4, in the position of the door need to use angle steel or wood keel for door cover;

5, pipe laying need to wear the pipe stuck.

The above discussion on the construction technology of the light steel keel partition wall and the light steel keel partition wall is briefly introduced here, and I hope to help you. For more information, please visit this website. Stay tuned.
