1. Project i, project overview of the construction of the exterior brick restoration project the outside bricks are fined to the original outside bricks; the requirement for the outside bricks is the same as the original colour and process of the original wall, and the pasting of the tiles is treated with the original stitching process, with the same materials scratched 3 mm thick at the grass-roots level. The outside bricks are preceded by a scaffolding of bamboo, followed by the removal of the concrete slurry and the original exterior wall requiring a part of the brick. The external walls are then sprouted into waterproof sand. Once the water-proof slurry has been finished, the bricks are put on and then the external wall bricks are washed. Construction preparation 1 material requirement (1) cement: cement from mine no. 42. 5 or ordinary silicate. A certificate of exit or a copy of the test shall be obtained and shall be used as a result of the test for more than three months. (2) leaning clay. (3) sands: fine sand, sifted before. (4) bricks: they shall be balanced in size, type, specification, pattern, colour, and must be consistent with the original outer wall bricks, the surface of the bricks shall be squared to the same level and thickness, and shall not suffer from defects such as lack of twig, loss of angles or fractures. (5) quality requirements should be met, e. G., 801 glue and mineral pigments. 2 the main machines are weighs, iron plates, 5 mm sifts, window sifts, carts, large buckets, small buckets, flats, wood plasters, iron plasters, bars, bars, bars, feet, square feet, iron-level feet, grey slots, spoons, mills, brushes, wirebrushes, brooms, maxes, hammers, chalks, small white wires, rags or cotton wires, steel blades, small shovels, hand-held electric saws, slits, slits, sews, pallet boards, hammers, cartridges, nails, red pencils, lead wires, tool bags, etc. 3 operating condition (1) the use of bamboo scaffolding shall be supported and installed in advance, and its vertical poles, etc., shall be removed from the wall and door corner 153, 0200 mm. The shelf would have to be high enough to meet the construction requirements. (2) the pre-positioning of holes and drainage pipes shall be completed, the doors and windows shall be fixed and the cracks shall be clogged with 1:3 concrete sand, and the embedded material used in the sews on the windows of the aluminium alloy doors and windows shall conform to the design requirements and shall be clogged and pre-stamped with protective film. (3) the floors of the walls are cleaned and pre-filled with scaffolds, windowsills, etc. (4) selection of bricks by the size and colour of the bricks and their sorting for storage. (5) large areas should be sampled and sampled to determine the construction process and operational points, and submitted to the construction staff before doing so. Once the template has been completed, it must be certified by the quality review department before the team can be organized to work according to the template. The technical preparation works, due to the large number of lines and the fact that they are side-lined, make it difficult for large areas and lines to sew, to separate the layers, ensure local coordination and integration with the whole, and avoid the cutting of large areas. At the branch, each layer is separated and the sew is adjusted between 5 and 6 mm. Iii. Brick construction on the outer wall (1) process: grass-roots treatment of the hanging vertically, set-up, break-out of bricks with a line of grey cakes and a line of ground sand-balls, immersion of bricks and bricks on the sides of bricks; cleaning of the outer wall: examination of the cavity of the wall, flattening of the bricks or concrete that emerges from the wall. The remaining sand, dust, dirt, oil stains, etc. Were removed from the walls. (2) grizzly cakes: depending on the situation on the ground, hanging vertically, looking for rules and pastings. (3) the brick wall shall be nailed to the wire at the junction between the brick wall and the plume: the brick wall shall be nailed to the ten*10 wire at the junction between the plume. The width of the wire is 300 mm wide per side. Six bulge tube plums set a fixed point and span 450 mm. (4) brush interface: after cleaning the dust from the wall, full of the interface. To increase the glue of the ash layer and the wall. Reduced dust-covered empty drums, detachment. (5) grass-roots plaster: after a wet day ahead of schedule, a glass of 107 gel cement plaster with a water weight of 15 per cent, followed by a head-to-head plaster with a ratio of 12. 5 or 13 and a 20 per cent mass of 107 gel, a thin layer of plaster with a plaster. For the second time, the slurry of the same match was used to level the band, with a short bar, with a low cavity pre-filled, and finally with a plaster. Once the bottom dust has been wiped out, the next day water is poured for conservation. (6) bricks, bullet lines: bricks can be discharged as required by drawings when 6 to 70% of grass-roots ash is dry. A vertical and horizontal control line is inserted on the bottom slurry. From the top floor, it can begin to be hung vertically by a specially designed large line of barbed wire, followed by the setting of points and the making of grey cakes according to the specifications and sizes of ceramic bricks. The line is controlled horizontally by the floor, with the vertical line being controlled horizontally by the main angles and interlayers, with the dome being the baseline. At the bottom of each layer, this is used as a reference point, 6 to keep the bottom ash straight and square. At the same time, care should be taken to highlight the water slopes and drip lines (torts) on the facade, the waist, the windows, the rain caps, etc. It is not less than 10 millimeters deep, coherent and must be a brick. (7) the window and window openings are properly repaired: bricks are drained, the door and window openings are inspected behind the bullet line, the width of the door and window openings is adjusted to the vertical line, and the height above and below the window openings is adjusted to the perpendicular line. The location of the door and window openings is consistent with the design layout requirements. (8) selection of bricks: the selection of bricks requires the correctness, flatness, non-fissileness, the soundness of the angles, the balance of colours, the absence of cavity and twisting. No, no, no. (9) standard points: standard points are pasted with scrap bricks on the ground floor slurry, with the angles of the bricks raised and the angles used as the standard for flatting the surface of the paste. (10) base ruler: the standard for the lower exit of the first brick is set on the basis of the height of the lower bounds of the calculated bottom brick. Bottom 7 is generally about 1 cm lower on top of the floor, so that the floor covers the wall. (11) placing bricks: once the floor of a brick is mixed with 107 cedar cement coatings, it is attached directly to the bottom ash. The gate or angular angle shall be marked by a row of bricks erected at a distance of 2 m from the long wall, which shall be used as a criterion for the verticality and flatness of the surface of the wall and shall then be applied to the attached line on both sides. The tiles leave a gap as required by the design (general 3-8 mm). (12) embedding the edges: sideding with bricks of fittings attached to the face. (13) sutures: when the symptoms of self-censorship and imperviousness are covered, they are sewn with a special suture. 5. Detailed figures for each section. Material control 1. Material control: entry of materials, semi-finished products and finished products is subject to rigorous testing in accordance with the specifications, drawings and construction requirements and is ineligible for immediate exit. Establish a robust system of material testing and verification. The products that were not qualified for the second test were strongly withdrawn. The sub-sector works require a secondary examination of the materials, including cement, sand and bricks on the outer wall. Cement: this project uses regular 325 silicate cement, which must have a certificate of accreditation and stability to meet the requirements. 7-day strength and 28-day strength of secondary tests. In general, the seven-day strength will be sufficient. Sands: rough or middle sand, sifted before. The field sample was tested and used. Bricks on the outer wall: the surface should be flat and the colours consistent. Surface sizes, water intake and anti-frozenness must meet regulatory requirements. The second check is valid for use. The materials used to find layers, binds, glues and stitches and embedding should be tested prior to the construction of the facade paste. The design requirements are met before they can be used. 2. Bricks shall paste quality indicators and means of testing (1), the types, specifications, colours, and patterns of coating bricks shall conform to the design requirements. Installations are solid, non-slanted, elastic and cracks. (2) the surface shall be flat, clean, colour-nine, to the extent that it is not subject to warp, damage, colour alteration, alkaline, stains, slurry flow marks, light colour loss. (3) the whole set of bricks is cut together, the edges are neat, and the length of the wall's skirts, kick lines, the face of the front of the door and window is highlighted. (4) the seam shall be filled with a dense, smooth, uniform width, slurred, coloured, and the bricks in the bright and bright corners in the right direction. 3. Professional construction guarantees that my company will have a professional construction team attached to the outside wall. Professional construction technology and first-class construction management. At the same time, our company has a comprehensive system of management, training and evaluation of the construction workforce, which fundamentally ensures the quality of the workers required for the project, thereby providing a solid foundation for the quality objectives of the project. 5. Implementation of the system of inspection and acceptance (1) self-inspection: upon completion of the construction of each sub-project, the construction team is required to perform a self-inspection of the products under construction and, if quality acceptance standards are met, the team leader completes the self-inspection log form. (ii) cross-checking: following an examination of qualified sub-engineering projects from 10 to 10, the construction teams organized by the technical head of the project department and organized by the sub-officer and the quality officer shall conduct cross-checks, which shall be addressed carefully and in a timely manner. (3) hand-over inspection: the upper and lower stages of the process are deemed to meet the requirements of the sub-project quality inspection and acceptance criteria by means of cross-checking, and only after the completion of the handover records by the parties and the signature of the sub-contractor is approved by the sub-contractor prior to the completion of the sub-process, with the personal supervision of the project technical officer. 6. Quality issues that are prone to occurrence: 6. 1 low-level surface deviations and poor grass-roots processing or construction, such as too tight as dusting each layer; weak porcelain bricks and no water spilling, and poor bonding between layers, can easily create empty drums and fall。6. 2 slurry co-ordinates are non-existent, density control is poor and sands contain excessive amounts of mud; or, on the same construction side, the use of several different co-comparison slurry, resulting in different dry contractions11 and empty drums. Work should be done in strict compliance with process standards and emphasis should be placed on grass-roots processing and self-censorship, and empty drums should be immediately returned to work. It would be appropriate to complete the whole or the independent part once. 6. 3 discrepancies in the break-up and unevenness of the wall: mainly due to the fact that the structure was not carefully calibrated to the size of the drawings prior to the construction, which was not sufficiently handled at the grass-roots level; and the low number of greycake control points, which resulted in the unevenness of the wall. Owing to the fine lined bricks, the sizes of each of the outer wall blocks were not consistent, the selection of bricks was not fine and was not properly performed, which resulted in the slitting of the partitions. The bricks of the same size should be placed on a wall. The non-bullet work should be handled exclusively. 6. 4 the yin-yang angles are different: they are mainly the result of non-compliance with the rules, the formula and the rules. 6. 5 wall-based contamination: mainly because the sew is not purified in a timely manner or because of other types of work and processes, such as contamination of the wall. They can be washed with cotton silk 12 and hydrochloric acid and washed with water. V. Safe construction management of the exterior wall is the focus of the project's safe construction management. In response to the importance of the security construction of the outer wall, our company has put in place a strict security operating system for the construction of the outer wall. 2. Safety belts shall be worn while working on the outer shelf by workers who paste outer wall bricks. 3. Items, such as materials and tools, that are not allowed to go down or to be dumped while operating on the outer shelf. 4. In the course of their operation, they shall maintain their jobs and strictly prohibit the operation of alcohol. 5. It is prohibited to wear slippers, heels, skirts, slippers, nailed shoes, etc. 6. The exterior scaffolding, protective facilities, security signs, warning signs and scaffolding sidewalls shall not be removed without unauthorized removal, which must be reinforced and agreed to by the construction manager. No rest and sleep on scaffolds shall be allowed. 8. The tool shall be loaded into a tool bag at any time when it is in use. 9. Scaffolds 13 and the sides of the plate should be secured to prevent the sounding board. 10. Overload risk of scaffolding: the scaffolding shall be mounted on a load not exceeding 270 kn per square metre, i. E. The laying of bricks on scaffolding shall not exceed this standard. 11) persons who engage in external wall pasting must be in good health and must not be allowed to perform high-altitude work because of hypertension, anaemia, severe heart disease, mental illness, diarrhea, depth near-sightedness at more than 500 degrees, as well as persons who have been examined by a doctor and found unfit for high-altitude operations. Medical examinations are carried out once a year for personnel working on the climb. (1) when operating on the platform, on the side of the house, the face shall be outwardly bound with safety belts. (2) do not work too hard on the outer shelf to prevent the loss of balance and attachment. (3) operation shall cease in the event of heavy rain, fog and strong winds above class 6. (4) the pasting of outer wall bricks does not permit night work. Workers are required to check the safety of the outer scaffold when they are on board and to meet the operational requirements; are the points of connection robust; are the outer scaffolds in place; and are seat belts and accessories intact? The construction will be completed only after ensuring that the construction measures meet security requirements. Special attention should be paid to the control of the construction load on scaffolds. The ministry of project services has a professional scaffolder who carries out daily inspections of the scaffold, and the operator shall immediately notify the scaffolder of the need to repair and strengthen the outer rack and shall not alter it without permission. The mountains are full of white bones, and the green water hangs their souls。
