2023-09-01- readings1. Fabric preparing:
The polymer mortar bonding coating, plastering covering, and window fiber content fine mesh towel required for the undertaking. All supplies must have certificates of conformity and be sure prompt provide.
2. Building preparation:
1. Technical arrangements: ① Pertinent workers engaging in the construction should carefully acquaint themselves with all the drawings, construction approaches, and expert the construction methods. Specialized difficulties and pulling issues should be settled and applied before development, and style adjustments and negotiations must be dealt with promptly. ② Get ready development specialized disclosure actions over time and finished the authorization methods. ③ Allocate special personnel to be accountable for the selection and arrangement of technical info. ④ Arrange coaching and construction The employees are proficient in the development process of the exterior wall heat retaining material and plastering covering. ⑤ Jot down the written technological disclosure for each procedure, and arrange personnel to make the disclosure just before the start of function. ⑥ Do a excellent career of making the processing machinery.
2. Evaluation and approval just before design and construction functioning problems: ① The building foundation must complete the examination and recognition in the development and oversight system just before thermal efficiency building could be performed. Examine the bottom level having a 2-gauge ruler along with a wedge-molded feeler evaluate, and employ it for an acknowledgement record. ②The top of the foundation training course has to be neat and firm, free from debris, grease, loosened grout, and so forth. ③ The building and acknowledgement of the external wall space and external surfaces windows and doors is completed, as well as the bottom fulfills the appropriate needs of GB50300-2001 "Unified Standards for Development Good quality Acknowledgement of Building Technology". ④The air conditioning opening and air cooling bracket are put in. ⑤Construction gear ready to fee electric mixing machine, slotting device, electrical hammer, trowel, pallet, okay-toothed hands discovered, wallpaper blade, take cable, coarse sandpaper, measuring tools, 2-gauge ruler, yin and yang sides, ink fountain, Outside power supply device. ⑥Climatic situations The environment and base temperatures of your functioning site shall not lower than 5°C, the blowing wind power shall stop being in excess of stage 5, and development cannot be completed in rainy times. ⑦Construction operations conditions The development procedure of the energy efficiency facade of your walls should satisfy the circumstances of construction procedure and security.
3. Development method:
(1) Design method: The building of the regular coating takes the layer because the device, and also the sanding, meshing, and plastering are carried out from top to bottom, along with the span of streaming drinking water throughout design at space temperatures is much more than 12 time.
Particular approach flow: bottom treatment method → cable establishing → mincing and mending, secret examination → plastering mortar on the bottom covering → pressing in to the travelling bag and strengthening fine mesh towel → pasting the mesh towel and pressing in the mortar → plastering the surface level of mortar → mending the hole and looking at for approval →Brush water-proof flexible color or dealing with bricks externally.
(2) Development operations: 1. Series placing: ① Engage in control line: In line with the technical requirements of your constructing facade design along with the external wall structure insulation and outside artwork layer, show up the horizontal and straight handle collections in the outer doors and windows, expansion seams, decorative seams, and so forth. about the wall surface ② Hang up the reference point collection : Dangle straight datum lines in the yin and yang edges of the exterior wall of the constructing along with other necessary areas, and suspend horizontal facial lines at appropriate placements on each floor to manipulate the verticality and flatness of the plastering covering.
2. Preparing of polymer exterior energy insulating material bonding mortar: ① Focused mixing: prepare polymer mortar in accordance with the requirements in the polymer emulsion product or service specs ② A unique particular person is responsible for this job.
3. Grinding: ① 4 several hours following the efficiency table is pasted, and once the adhesive actually gets to a specific link power, utilize a special mincing tool to grind the unevenness on the surface in the insulating material board. Grind within a route parallel to the joints from the efficiency table ② After mincing, utilize a brush or compressed oxygen to clean up up the trash produced by the mincing operation.
4. Prepare polymer emulsion external thermal insulation plastering mortar and get ready plastering mortar according to the specifications of your manufacturer's merchandise instructions.
5. Plastering mortar for that base: Right after the heat retaining material level of your polystyrene board is done and checked out and approved, the plastering design with polymer mortar is carried out, along with the plastering is divided into 2 types: the base level as well as the surface level. For the overall put additional insulating material board, firstly apply a level of polymer mortar to complete the trapezoidal groove, use mortar to roughen and stage, and protect the stainlesss steel wire fine mesh by 1 to 2 millimeters. For that pasted plastering bottom polymer mortar, the fullness is operated at 2-3mm. Concurrently, the pre-inlayed overturned fine mesh fabric is pressed in the mortar, as well as the strengthened fine mesh material employed in the four corners from the door and home window as well as the yin and yang edges are immediately pressed into the mortar. midst.
6. Laying grid towel: Hit the grid fabric in the primary polymer mortar, then work with a trowel to flatten the grid towel in the middle to the environment, with the curved aspect from the fine mesh material experiencing inward. It is needed to be smooth and compacted, and the mesh material is strictly disallowed from wrinkling the mesh cloth must not be pressed too strong, and also the surface area must be open to the underlying mortar. The duration of just one net should not be in excess of 6 yards. When there is an overlap inside the paving, the length of the overlap should be satisfied, which happens to be 100 millimeters from the side to side route and 80 mm in the top to bottom path.
7. Area layer mortar: Prior to the foundation coating mortar condenses, use the surface coating mortar. The fullness is operated at 1-2mm. Prevent hollowing. The whole thickness from the bottom layer and surface coating should not be more than 5 mm.
Throughout the intermittent time period of construction, the plastered work surface must be left in the normal disconnection areas, for example enlargement bones, yin and yang corners, grid joints, and programs, and many others. If it is on the huge region, the outer lining coating mortar must not completely protect the put grid fabric, and also the bottom layer mortar in the grid fabric must be rubbed in steps, and the length in between the rubbing must not be less than 150 millimeters, in order to prevent the flatness of your mesh material overlap. Deviation surpassed.
8. Treatment of "seams": ① Expansion joint parts, keep growth bones with the side to side layer for each coating, polystyrene boards are put in foam plastic rounded rods in the development joints, and also the growth joints are loaded with lotion as soon as the benzene boards are pasted. Depart the snow ②Grid seam: When making the grid seam, reduce the groove, bury the grid towel inside the groove, and put the plastic-type material U-molded strip to level together with the work surface covering well before plastering the surface covering mortar ③Drip groove : Very first eliminate a groove on the polystyrene table, the groove is greater than the drip groove, put the grid material in to the groove, mixture it with polymer mortar, and after that place the plastic groove into the groove ④Decoration Outlines: Elaborate collections ought to be packaged into concave or convex styles in accordance with the impact of design style facades. The convex design must be embodied by polystyrene panels. On this page, the mesh cloth and plastering mortar cannot be disconnected. For the position of the series, adhesive the highly processed polystyrene board on the related placement. The table along with the collection are built-in. If the range protrudes over 100 in the wall, anchor pins are required.
9. Strengthening coating technique: Once the outside heat retaining material covering flows and rammed, it is not necessarily needed to produce a support layer when laying bricks on the exterior, but it is essential to create a strengthening level once the exterior wall is paved with bricks.
①Reinforcement covering of your initial covering: Thinking about the affect opposition needs of the walls surface of the initially layer, a layer of mesh towel is added on such basis as normal additional efficiency, and another coating of plastering mortar is used to improve the impact level of resistance. The complete thickness from the plastering mortar at the bolstered aspect is operated at 5 ~7 millimeters is suitable, and development important joints needs to be still left within the support covering process and standard exercise. As soon as the very first wall surface is pasted with marble surface area level, the marble area coating is pasted on the insulation board, so the size in the polystyrene board is 4 cm, and 1.2 thick 20×20 galvanized stainlesss steel cable mesh is additional right after the polystyrene table is pasted. , Use special temperature preservation pins to fix the metal wire mesh, implement polymer accommodating anti-cracking mortar, the density of your mortar is 1 cm, rub it by using a solid wood trowel, after which remember to brush it with stretchy painting.
② Strengthening level for doorway and window openings: The polystyrene boards at the four corners in the front door and home window availabilities needs to be staggered, no bones are made it possible for, and a covering of 400×200mm fine mesh fabric is put into the four edges over the path of 45 qualifications for encouragement, along with the strengthening mesh is in the huge area fine mesh Under the material.
4. Quality requirements
