The setting out lines should be clear and the positions should be accurate. Lay out the lightweight partition walls to be cut according to the requirements so that later cutting can be done according to the setting out lines. The width and length of the partition wall are reasonably cut, thereby maximizing the loss rate of the lightweight partition wall, thereby reducing the cost. At the same time, measuring the dimensions and cutting them after laying out the lines can effectively plan the splicing area, width and load between each board. The uniform distribution of force can avoid the local load concentration of spliced lightweight partition walls, which may easily cause deformation, cracks or hollows at the connection between boards or between boards and doors and windows in later construction, as well as surface plastering quality problems, etc. Greatly improve the connection strength and deformation resistance between boards and extend the service life;

S3, cutting

Cut the lightweight partition wall according to the size measured in step S2. The lightweight partition wall entering the site must meet the specification requirements of "GB15762-2020 Autoclaved Aerated Concrete Panels" before it can be shipped to the construction site for installation; maintenance period: Lightweight partition walls should be stored in the factory for 5 days after leaving the kettle before leaving the factory. The dry density, compressive strength, and drying shrinkage value of the board should meet the requirements of the specification. During the cutting process, ensure that the reserved door openings and window openings are Lightweight partition walls all have L-shaped transfer parts. The horizontal spacing between L-shaped transfer parts is not less than 100mm. A single-piece door headboard is used above the reserved door opening, and a single-piece window is used above the reserved window opening. The roof board is a single-piece door headboard or window top board that uses the L-shaped transfer parts of the lightweight partition walls on both sides of the door or window opening to greatly increase the stability of the installation of door frames and windows in the later stages of this construction method. sex, to avoid the light partition wall located above the door or window opening being directly pressed onto the door frame or window, which may easily lead to deformation, cracks or hollows at the connection between the board and the door and window, as well as surface plastering quality problems, etc., that is, to further improve The connection strength and deformation resistance between boards are improved and the service life is extended;

S4. Install embedded parts and steel plate clamps

The embedded parts include φ8x200 steel bars and φ8x250 steel bars. The φ8x200 steel bars driven into the ground at an angle of 45 degrees are placed between two adjacent pieces of the bottom lightweight partition wall. They are located between the topmost lightweight partition wall and the top surface of the structural wall. Set up φ8x200 steel bars to be driven in at an angle of 45 degrees. The light partition wall located in the middle layer is driven into a transition area between two adjacent spliced pieces at an angle of 45 degrees. In S2, fix the U-shaped card on the top of the wall, and fix the L-shaped card on the lightweight partition wall cut in step S3. Each lightweight partition wall contains at least one L-shaped card; Diagonal 45-degree steel bars of different lengths as well as U-shaped and L-shaped clips are installed between the partition wall and the ground, the lightweight partition wall and the lightweight partition wall, and the lightweight partition wall and the top surface of the structural wall, that is, increasing the plate and The splicing connection strength and deformation strength between boards and between boards and walls, while increasing the stress distribution points between boards and between boards and walls, and finally combined with the later mortar, latex and fiberglass mesh Grid stickers effectively achieve multiple reinforcements to avoid local load concentration on spliced lightweight partition walls that may easily cause deformation, cracks or hollows at the joints between boards or between boards and doors and windows during later construction, as well as surface plastering quality problems. occurs, thereby greatly improving the connection strength and deformation resistance between boards and extending the service life;

S5. Apply mortar

Add the ALC special adhesive to a proportion of water to make a paste, and apply it to the laying out area where the groove of the lightweight partition wall contacts the structural wall and floor. It must be spread evenly to ensure the LC special adhesive. The agent is full, and the excess mortar can be fully squeezed out during installation to avoid the need to fill a large area with special mortar after installation, causing the mortar at the junction to be unsaturated and easily causing deformation, cracks or voids at the connection between boards or between boards and doors and windows. Drums and surface plastering quality problems occur, thereby greatly improving the connection strength and deformation resistance between boards and extending the service life;

S6, board installation

Use vertical plate tools to align and splice the lightweight partition walls, squeeze out the ALC special adhesive from the joints, and use a crowbar to move the lightweight partition walls back and forth to ensure the ALC between the upper and side panels of the lightweight partition wall. The special adhesive is used for dense bonding to avoid the existence of holes between the joints of the boards, which may cause deformation, cracks or hollows at the joints between the boards or the joints between the boards and doors and windows, as well as surface plastering quality problems. , thus greatly improving the connection strength and deformation resistance between boards and extending the service life. Then first scrape off the ALC special adhesive protruding from the joints of the lightweight partition board, and finally use wooden wedges to seal them Temporarily fixed, the wedge-shaped structure of the wooden wedge can be used to stably place and fix the lightweight partition wall, and adjust the position of the lightweight partition wall during the later step S7 correction construction to avoid the lightweight partition wall from being damaged due to excessive load during the splicing process. Shifting, skewing, or squeezing out the mortar between boards creates voids, which may cause deformation, cracks or hollows at the connection between boards or the connection between boards and doors and windows, as well as surface plastering quality problems, etc., which will greatly affect the quality of plastering on the surface. Improve the connection strength and deformation resistance between boards and extend the service life;

S7, calibration

Use a ruler to check the flatness and verticality of the wall surface of the spliced lightweight partition wall, and adjust it to within the standard range. Then use a wooden wedge to tighten the lightweight partition wall at the lower end of the lightweight partition board, and use a nail gun to Fix the lightweight partition wall with the L-shaped card on the adjacent lightweight partition wall or the lightweight partition wall and the U-shaped card, so that the lightweight partition wall can be installed on wooden wedges, L-shaped cards, U-shaped cards and pre-embedded Pieces of φ8x200 steel bars and φ8x250 steel bars are stably shaped under the multiple effects until the ALC special adhesive dries;

S8, grouting and patching

After installing the corrected lightweight partition wall for 1 day, use a special installation polymer slurry and add water in proportion to make a slurry, fill the joints between the upper and lower seam boards, pull out the wooden wedges and fill them with mortar , use the ALC special adhesive to dry and cure for 1 day. After one day, it will have a certain supporting bearing capacity. Pull out the wooden wedges and fill them with mortar. This will achieve phased construction, effectively ensuring the good shape of the lightweight partition wall, and avoiding the later filling of the mortar with the ALC special adhesive. The long time interval between bonding construction may affect the solidification stability of the support;

S9, apply anti-cracking cloth

3-5 days after the grouting in step S is completed, that is, after the special installation polymer slurry has dried and shrunk, use latex to affix 50mm fiberglass mesh cloth to the joints of the boards to further realize phased construction, and use latex Attach 50mm fiberglass mesh cloth to the joints of the boards. After the latex dries, the 50mm fiberglass mesh cloth will further improve the connection strength and deformation resistance between the boards and extend the service life.

Furthermore, in step 3 of this technical solution, when the end height of a single lightweight partition wall is insufficient to completely seal the wall to be blocked, a patching board should be used for sealing. When cutting the patching board, it is necessary to ensure that adjacent The transfer part between the two vertical lightweight partition walls is assembled in a Z-shape, and the vertical staggered distance between the two lightweight partition walls is not less than 300mm. That is, the staggered splicing of the lightweight partition walls is used to further increase the board size. The connection strength and deformation resistance between the plates and the distribution of the load force are more even. Due to the Z-shaped staggered splicing between the plates, the embedded parts and steel plate clamps installed in step S4 are in the whole piece to be installed. The regional distribution is even, and at the same time it helps to distribute the load of the spliced lightweight partition wall evenly, that is, it further increases the connection strength and deformation resistance between the panels and makes the load intensity more evenly distributed.

Furthermore, in this technical solution, the embedded parts in step 2 also include profile steel welded in the horizontal and vertical directions. The profile steel can be I-shaped steel, square steel or double channel steel. When the two lightweight pieces are used in step 3, When the end height of the partition wall is insufficient to completely block the wall to be blocked, profile steel should be used to vertically divide the wall; that is, the large area to be installed can be divided into smaller installation areas by welding the profile steel. This further increases the support stability, connection strength and deformation resistance between plates and makes the load distribution more uniform.

Furthermore, in this technical solution, the φ8x200 steel bars or φ8x250 steel bars located near the profile steel are first driven into the lightweight partition wall and then welded to the profile steel, that is, the male and female falcons of the lightweight partition wall are used to reinforce the welding between the steel structures. Groove splicing and mortar curing, as well as multiple curing of fiberglass mesh and latex, further improve the connection strength and deformation resistance between large plates, make the distribution of load force more uniform, and extend the lightweight partition construction using this method. Wall lifespan.

Furthermore, in step 3 of this technical solution, when the height of the upper wall of the door or window opening is greater than 600mm or the width of the door or window opening exceeds 1.5m, it is necessary to use a lintel plate equipped with steel bars to form a lightweight partition wall above the door or window opening. Supporting can further increase the load strength of the lightweight partition wall above the door opening or window opening, and the uniformity of load distribution, which can relatively improve the connection strength and deformation resistance between boards and extend the service life.

Furthermore, this technical solution sets the spacing of L-shaped cards to ≤600mm, and the driving distance of the L-shaped cards to the edge of the lightweight partition board is 80mm, thus avoiding the long construction period, tediousness, high cost or loss caused by excessively dense installation of L-shaped cards. Lightweight partition boards are easily broken due to stress, which may cause deformation, cracks or hollowing at the connection between boards or the connection between boards and doors and windows, as well as surface plastering quality problems, etc., which relatively improves the quality of the boards. connection strength and deformation resistance and extend service life.

Furthermore, this technical solution uses lightweight partition walls to install from the edge of the door opening to both sides in sequence. Partition walls with openings should be installed from the opening to both sides; partition walls without openings should be installed sequentially from one end of the wall to the other end. The lightweight partition walls or panels cut during construction should be installed at the inner corners of the wall or between the whole plates close to the inner corners to avoid door openings caused by installation errors in the installation gaps between the plates during the construction process. Or the size of the window opening is not up to standard and needs to be reworked, resulting in a long construction period or affecting the connection strength and deformation resistance between boards.

Further, this technical solution uses one or more combinations of a total station, a theodolite, a level, a construction line, an ink fountain, a pencil and a line hammer to pay out the wire in step S2, thereby realizing different ways of setting out the wire. Convenience, accuracy and re-checking and calibration can avoid the skewing of later splicing of panels due to poor placement accuracy, which may cause the lightweight partition panels to easily break due to stress and cause the joints between panels or panels to connect doors and windows to easily appear. Deformation, cracks or hollows, as well as surface plastering quality problems occur.

Furthermore, in this technical solution, the dimensions measured in step S2 also include the location, size and quantity of pipelines, distribution boxes, sockets and switch boxes. The depth of the slotted wires shall not be greater than 1/3 of the plate thickness, and the width of the slotted wires shall not be greater than 1/3 of the plate thickness. It shall not be larger than 50mm. For lightweight partition walls that need to be grooved on both front and back sides, the distance between the two grooves is ≥ 150mm. For grooves with a depth greater than 1/3 of the board thickness or horizontal grooves along the board width, a lightweight partition wall with a thickened protective layer must be used. plate;

Further, this technical solution also includes the following steps:

S10, slotted buried pipe

After applying the anti-cracking cloth for 7 days in step S9, use a portable electric saw to cut the wire trough according to the position, size and quantity of the pipelines, distribution boxes, sockets and switch boxes measured in step S2 to avoid ALC special adhesive, special The installation of polymer slurry, latex and fiberglass mesh cloth is not completely dry, causing the connection between boards to easily break due to stress, causing deformation and cracks to easily occur at the connection between boards or between boards and doors and windows. Or hollow drums or surface plastering quality problems occur. After the line pipes, distribution boxes, sockets and switch boxes are installed, use mortar to fill them up. Finally, apply the batch of base paint. If you are applying ceramic tiles, you don’t need to scrape them. Gray, you can directly paste the tiles on the wall board with cement slurry, or you can directly paste wallpaper, wood trim, etc. The vertical pipelines on the partition board should not be located at the joints between the vertical boards. After the pipelines are laid, use special ALC The adhesive is filled in, and the surface is slightly lower than the wall panel surface by 2mm, and then the special repair material is used to fill it up twice, that is, the laying of concealed pipelines supporting the construction of lightweight partition boards can be realized, and the grooving of hidden pipelines can be avoided. As a result, the connection between boards or between boards and doors and windows is prone to deformation, cracks or hollows, as well as surface plastering quality problems.
