The difference between the olecranon and the gutter is that there is a difference between the shape of the olecranon and the gutter. In addition to the olecranon drip line, the gutter is a U-shaped gutter.
Exterior wall divider construction plan four, construction preparation
4.1 Material Preparation
4.1.1: After investigation, there is no pvc plastic line with a width of 20mm and a depth of 15mm in the finished product. Contact the manufacturer to customize the mold according to the color template and sample image provided by Party A. The production cycle lasts for about 10 days. At least one batch must be produced. Produce 20,000 meters.
4.1.2 According to the amount of work, starting time, construction time required to arrange an appropriate storage space, mixing site. Organize the material entry time, control the number of material arrivals, make a good entry record, and report the amount to the supervisor for confirmation. Do a good job of material release records and collect the factory certificate for each batch of materials.
V. Construction process flow structure Primary treatment - lifting vertical lines, bullet control lines, cakes - retesting the flatness of the grass - brushing interface mortar - the construction of the underlying plastering mortar - longitudinal strip longitudinal control line - - Inlaying and dividing strips - Two-story cement mortar troweling - Acceptance of external wall plastering layer - Coating construction VI. Construction process description
6.1 Make a mark. Before the construction of the plastering plaster layer, a construction thickness mark shall be made on the wall surface. Follow the steps below to make the plastering patch:
6.1.1 Check the wall surface flatness with a 2m-feet first on each floor and check the verticality of the wall with a 2m pallet.
6.1.2 At a distance of about 10cm from the top of the floor and at a distance of about 10cm from the big wall of the Yin/Yang angle, a 30mm × 30mm square cement board is used as a standard cake paste according to the thickness of the vertical control line of the steel hanging at the big corner.
6.1.3. After the standard cake is fixed, pull the horizontal control line between the two levels of the cake. The specific method is to insert the small garden nail with a small line into the standard cake, straighten the small line, and make the small line control better than the standard paste. The cake is slightly higher by 1mm and several standard cakes are pasted horizontally at 1.5m intervals between the two cakes.
6.1.4 Hang a vertical line about 10cm away from the bottom of the floor with a line drop, and paste standard cakes 10cm above the corner of the big wall. (After the floor is high, they should be completed by two people.) Then stick the standard cakes in a vertical direction about 1.5m apart.
6.2 Interface mortar construction After construction of each layer of cake application, interface mortar construction shall be carried out. The interface mortar shall be prepared with 1:1 cement and fine sand, mix with water and add white water glue with 20% water, and stir with paint. The interface mortar is evenly painted on the wall surface. Note that the interface mortar layer should not be applied too thick.
6.3 plastering mortar construction
6.3.1 The interface mortar can be applied after the mortar is dry.
6.3.2 In the preparation of plastering mortar, a special person shall be set up for the stirring to ensure the accuracy of the mixing time and the amount of water added. The quality of the agitation at the construction site can be judged by observing its operability.
6.3.3 The plastering mortar shall be completed by layering operation. The thickness of each plastering shall not exceed 10mm, and the layered plaster shall be equal to the thickness of the gray cake. The construction interval shall be 24 hours for each layer.
6.3.4 Plastering mortar The bottom layer is plastered in the order from top to bottom and from left to right. The thickness of the plastering layer of the plastering mortar is to be leveled with the ash cake. After smearing the entire wall, use a big bar to rub it back and forth across the wall, go high and low, and then press it again with an iron trowel to make the surface smooth and consistent in thickness. Plaster mortar should pay attention to clean floor ash during construction, and ground ash should be used again in 4 hours.
6.4 inlay and divider construction
6.4.1 After the construction of the bottom layer plastering is completed and the flatness is concealed, the construction of the partitioning strip can be carried out. In the construction, one facade is the construction section.
6.4.2 Eject each layer of horizontal control line on the bottom plastering surface; pop up the vertical control line on the outer wall corner, exterior wall door and window hole. Then according to the requirements of the drawings and the size of the pop-up construction of each floor separator line.
6.4.3 Use hard-soled cement slurry (admixed with 20% of water) according to the emplacement and embedment to fix the partition strips. The edge of the cement is made into a triangle, and the partition strip is pressed to a thickness of 8mm. The next day the wet water is maintained. Pay attention to the degree of horizontality while checking, and the deviation from the bullet is controlled within 2mm.
6.4.4 After the partition strip has a certain strength, the construction of the plastering surface layer can be carried out. The construction method is the same as that in section 6.3.4. The plastering surface and the partitioning strip are flattened and flattened with an iron plate without any rough surface or sanding phenomenon.
6.4.5 Remove the mortar in the separator, and water conservation 2 times every other day for one week.
6.4.6 After plastering mortar is completed, a complete quality inspection shall be conducted according to the requirements of the inspection lot. On the basis of the self-qualification, the construction quality records were collated and submitted to the supervisor and Party A for concealed inspection and acceptance.
Seventh, the outer wall kerf process construction As the exterior wall separation joint method is post-increment design, the site 13#, 16#, 9# building external wall plaster has been completed construction, in order to achieve decorative effects while reducing construction costs, decided on the above 3 The exterior wall of the building is used for slotting and molding.
7.1 Lines
7.1.1 Eject each layer of horizontal control lines on the bottom plastering surface; vertical control lines are ejected on the outer wall corners, exterior wall doors, and window openings. According to the requirements of the drawings and the size of the pop-up construction of each layer separator line.
7.1.2 According to the requirements of the drawings and size of each layer of separation pop-up construction line, construction line width 26mm. The sequence goes from bottom to top.
7.2 Slots are cut by cutting machine according to the construction position. The cutting depth of the cutting machine is adjusted to 20mm and the cutting is fixed. After the cutting is completed, the flat steel braze is used to remove and the mortar pieces in the seam are removed. The depth of the crack is removed. Not less than 18mm. Check that the slash straightness is controlled within 3mm.
7.3 Insert the dividers. Use a small brush to clean the dust in the slits and moisten the water. Fill the gap with a 10mm thick plain cement mortar (add 20% water to the water) and press the pvc divider into the seam. Excess cement mortar. Cement mortar should be filled with pressure lines, pay attention to control the consistency of cement mortar, not to flow through the joints, grouting edge seams prevail, depending on the site temperature control.
