二、Construction methods and technical measures

1. Process flow

1.1. Clean, measure and put out the light partition wall and the contact parts of structural walls and floors at the base level

1.2. Double-check the bullet line

1.3. Install and calibrate the partition wall with saw board sizing

1.4. Mortar on the bottom of the filling board, grouting to repair joints and sticking anti-crack cloth

1.5. Slotted wire-buried pipe plaster and coating

1.6. Plate seam and wall repair

1.7 Final acceptance

2. Key points of installation and construction

2.1 Basic cleaning of contact parts between lightweight partition walls and structural metope and floor

To thoroughly clean the roof, floor surface and wall of the partition board to be installed, the concrete structure surface in contact with the partition board must be smooth and compact.

2.2 Put out and carry the partition board

The elastic base line at the wall panel installation site is perpendicular to the floor or beam base line to ensure the flatness and perpendicularity of the wall panel installation and indicate the position of the door. After the wall panel enters the site, according to the thickness of the wall panel, people or machines are used to lift the wall panel to the installation site for flexible handling.

2.3 sawing plate

When the height of the wallboard is insufficient, a patch is used to cut and adjust the width and length of the wallboard as required to reduce the wallboard loss rate.

2.4 sizing

Use professional installation to fill seam paste, wipe clean the surface dust of concave and convex groove of wallboard with dishcloth, wet the concave and convex groove of wallboard with water, and then wipe professional mortar in the groove of wallboard and floor baseline.

2.5 plate

Spelt good slurry wall plate moved to install location is good after, immediately to baseline, up and down with Jimmy wallboard pried from the bottom up, hard make near between plates, polymer mortar from joint extrusion, and then scrape off the wall surface sizing agent, must assure board with board between seam pulp full, then the temporary fixation with a wedge.

2.6 in place

Squeeze the wallboard so that the mortar is extruded from the joints, then scrape off the mortar that protrudes from the seams of the wallboard surface and hold it in place temporarily with wooden wedges.

2.7 correction

After the initial assembly of the wallboard, the professional crowbar shall be used for adjustment and correction, and the evenness and perpendicularity shall be checked with 2M straight ruler. After crowbar correction, wood wedge and reinforcement shall be fixed up and down.

2.8 Grouting seam repair

After installing the corrected wallboard for one day, fill the joints between the upper and lower stitching boards with special mounting paste, and pull out the wooden wedge to fill with mortar.

2.9 Stick anti-crack cloth

After the mortar is finished, after 3-5 days of dry shrinkage of the combined mortar, the fiber mesh cloth is affixed to the joint of the board with latex.

2.10 Slotted buried pipe

If you want to bury hidden pipelines, switch boxes, etc., you can use a portable saw cutting line slot installation, to be installed after the mortar repair can be.

2.11 Plastering and coating

Finally, paint the bottom of the batch can be applied. If you need to paste the tiles without scraping, paste the tiles directly on the wallboard with water slurry or directly paste the wallpaper wood veneer.

3. Technical measures

3.1 Before the partition board is installed, it must be checked and accepted by the quality inspection personnel and submitted to the on-site supervisor for inspection before it can be used.

3.2. The installation operator shall check the partition wall panel block by block, and shall not use the partition wall panel with specifications and sizes exceeding the allowable deviation or with serious appearance defects.

3.3 Channel steel shall be brushed to prevent embroidery. It must be firmly fixed according to the required quantity, specification and model. No less release, leakage or loosening is allowed.

3.4 In the process of partition board installation, when the pipeline needs to be slotted, use a cutting knife to cut, it is strictly prohibited to pick the groove at will.

3.5 When large water pipe wind pipe passes through the partition board, the width of each wall board shall not be greater than 600MM. Temporary support shall be made when exceeding the limit, and then channel steel or Angle steel shall be used to reinforce the upper edge of the entrance. The specific method can be decided after consultation with relevant technicians.

4, partition wall installation quality requirements

4.1. All materials used in the production and installation of partition wall panels must meet the relevant national specifications and shall not release harmful substances. All kinds of test reports are complete.

4.2 The quality, location and quantity of connectors used for partition panel installation must meet the requirements.

4.3 Partition board installation must be firm and the connection between partition board and partition board and surrounding structure must be reliable.

4.4 The partition board joints shall be disposed in place, installed in a vertical and flat manner to meet the requirements, and in a correct position without cracks or defects.

4.5 The partition board surface is smooth, uniform and clean with uniform and straight joints.

4.6 The holes, grooves and boxes on the partition board are in correct position, with square cutting and neat edges.

3. Various construction management measures

1. Protection measures for finished products

1.1 After entering the building, materials should be transported in time to prevent rain and snow from getting wet.

1.2 The partition board stacking site shall be flat and there shall be square wood liners under the boards. When unloading the boards, it shall be put lightly without collision. It is strictly prohibited to lift, lay flat or stack laterally at an Angle greater than 75 degrees.

1.3 In the construction, all professional jobs should be closely coordinated and the working procedure should be rationally arranged. It is strictly prohibited to reverse the working procedure.

1.4 When installing the embedded parts, the percussive drilling shall be applied to the inner wall of scraping putty, and no gouging shall be carried out.

1.5 It is strictly prohibited to transport cars to collide with the partition board and its doors and Windows.

1.6 After the partition board is stuffed with fine stone concrete, do not lean against objects on the partition board for three days to avoid loosening.
