Precast reinforced concrete partition board installation
1 range
This process standard applies to civil construction non-load-bearing inner partition installation.
2 construction preparation
2.1 Materials and main equipment:
2.1.1 prefabricated reinforced concrete partition board: the quality should be consistent with "reinforced concrete prefabricated components quality inspection and evaluation standards", should be factory certification. The wall plate should be marked with the model number and positive and negative numbers, covered with qualified inspection chapter.
2.1.2 electrode: the use of E43-type electrode, should be factory certification.
2.1.3 Connection plate: generally 40 × 60 × 40 × 4 (mm).
2.1.4 connecting bars: the general diameter of not less than φ10, length 100 ~ 120 (mm).
2.1.5 Cement: No. 425, No. 525.
2.1.6 main equipment: the use of the main structure of lifting machinery and tools.
2.2 Operating conditions:
2.2.1 in accordance with the location of the construction site layout plan shown in the location of storage partition board, storage site should be flat, solid, to prevent water, subsidence. Stow the partition plate of the inserted frame to be firm and stable. Partition plate should be stored.
2.2.2 according to the design drawings check board number, and check the board of the embedded iron pieces are complete, and the above debris, rust clean. The hanging rings on the partition board shall be firm and complete.
2.2.3 in the installation of the floor to clean up the installation site, in the partition wall adjacent to the main structure of the wall board to install the positioning of the elevation position line. In the floor, a good wall plane flat line position. The wall plate type is written on the outside of the floor installation location.
2.2.4 Check the structure of the wall and floor to connect the partition board embedded parts are complete, the location is correct. The omission should be re-burying buried.
3 operating process
3.1 Process flow:
Installation in place → inspection, correction → support, reinforcement → welding fixed → caulking
3.2 installation in place: partition board installed in two ways, one can be with the construction of the structure in the deduction floor slab before hanging into the hanging with the installation, welding; the other is in the buckle floor before the room needs Wall hanging into the room against the wall when the safe, to be installed after the artificial.
3.3 Check the calibration: check the model installed to prevent the occurrence of the phenomenon of the wrong board number. Installed in accordance with the floor has been playing a good position on the line placed wedge, put the stability of the wall, with the card in the rings part of the temporary support for the wall board card. Review the installation position, adjust the deviation, vertical correction with the care board.
3.4 Reinforcement: wall plate horizontal position and vertical position correction, the site in support of rings, the board will be the bottom of the wedge Rolling back tight to prevent displacement, skew. Board to sew under the height of 20 ~ 30mm is appropriate. It is strictly forbidden to place the partition board directly on the floor and do not add any treatment.
3.5 fixed welding: partition board position correction, the board embedded parts and structural walls (or partition wall) between the buried parts welded steel plate with a solid welding must be done on three sides surrounded by welding, embedded parts shall not convex Out of the structural wall.
3.6 caulking: partition board welding is safe, the surrounding gap are 1: 2.5 cement mortar twist plug dense, mortar mixed with 10% of the amount of cement 107 plastic, seam width greater than 30mm when filled with C20 tofu concrete twist real. When the slab mortar has a certain strength after the exit wedge, the wedge hole filling. Slab mortar should be done dense, smooth, straight corners, to facilitate decoration.
4 quality standards
4.1 Warranty items:
4.1.1 raw materials used should meet the design requirements and construction specifications, and a factory certificate.
4.1.2 The model, location and connection of the fixed node shall conform to the design requirements. Partition board should be factory "certificate."
4.1.3 with Dou Dou concrete or mortar to do the slit, metering to be accurate, packing to be dense, serious conservation. Its strength should meet the design requirements.
4.2 Basic Items:
4.2.1 Components location, node structure, connection anchorage practices, should meet the design requirements.
4.2.2 Connecting steel plate should be full of three-sided welding, full weld, welding wave uniform, welding slag and spatter to remove clean.
4.2.3 weld length and thickness of the weld meet the design requirements, the weld surface smooth, no burns, depression, welding, cracks, undercut, stomata and slag and other defects.
4.3 Permissible deviation items, see Table 4-42.
Table 4-42
Line item Allowable deviation (mm) Inspection method
1 verticality 3 with 2m care board
2 Axis position offset 3 size check
3 wall patchwork 5 with a ruler, wedge-shaped feeler check
4 Elevation ± Check with level or scale
5 protection of finished products
5.1 partition board stacking site should be flat, solid, not water or subsidence. Planks should be placed in the insert stand, below the pad of wood or square wood, to prevent breaking or bending deformation.
5.2 partition board transport and lifting process, should take measures to prevent fracture.
5.3 Installation of equipment to be perforated in the board through the wall when the board is strictly prohibited sledgehammer slam the wall, serious damage to the wall panels should not be used.
5.4 wall board correction, welding after the timely caulking, not before the caulking, the wedge wedge to wedge, not loose to prevent wall displacement.
6 should pay attention to quality problems
6.1 embedded pieces of displacement: the production of wall panels without careful control, to the construction caused difficulties.
6.2 partition board loading and unloading, transport, stacking do not pay attention to finished product protection to make the wall missing Corrugated angle: the wall is damaged, the application of cement mortar with 1: 2.5% D% 107 glue repair.
6.3 component production strong bottom of the pool is low, so that deformation of wall panels.
6.4 Welded partition board according to the provisions of the use of prepared steel plate connection to prevent welding is not strong. There should be no shortage of connecting pieces to prevent the number of welding points is not enough.
6.5 partition board installation, should sit slurry, caulking, to prevent pendulum float.
