Jinan rock wool board external wall thermal insulation system has excellent thermal insulation, sound insulation and fire protection performance, which can meet the thermal insulation and energy saving requirements of buildings, and is convenient to install, with obvious energy-saving and environmental protection effects, strong economic applicability, high cost performance and broad application prospects. Let's talk about the key points of the construction technology of rock wool board external wall insulation.
巖棉板外墻保溫施工技術(shù)的施工流程如下：
The construction process of rock wool board external wall insulation construction technology is as follows:
一，基層處理完成后，使用20mm厚的防水砂漿完成找平。二，在建筑物外墻面彈線，掛設(shè)基準(zhǔn)線，用滿粘法黏貼巖棉板。三，按8個/m2的數(shù)量為安裝錨固件，抹底層砂漿，壓入鋼絲網(wǎng)。四，安裝巖棉板固定件，抹面層砂漿，壓入耐堿網(wǎng)格布。
1、 After the base course is treated, use 20mm thick waterproof mortar to finish leveling. 2、 Snap the line on the outer wall of the building, hang the reference line, and stick the rock wool board with the full adhesion method. 3、 The quantity of anchors shall be 8 pieces/m2, the bottom mortar shall be plastered, and the steel wire mesh shall be pressed. 4、 Install the rock wool board fastener, plaster the surface layer mortar, and press in the alkali-resistant mesh cloth.
施工準(zhǔn)備
Construction preparation
施工工具包括攪拌機(jī)、沖擊鉆、鉆頭、切割機(jī)、手推車、鐵鍬、平口批刀、鋸齒批刀及鋁合金刮杠等。巖棉板、粘結(jié)劑、鋼網(wǎng)、錨栓及抹面砂漿等施工材料進(jìn)場后，應(yīng)放置在提前選定的干燥、清潔、易于施工的場地。建筑物的圍墻應(yīng)預(yù)留施工洞口和空調(diào)洞口，如果環(huán)境溫度在5℃以下、風(fēng)力超過5級或雨天，則不可進(jìn)行巖棉板外墻保溫施工。全部完成施工材料進(jìn)場、機(jī)械設(shè)備安裝、防護(hù)設(shè)施安裝及技術(shù)交底后，可以開展巖棉板外墻保溫施工。
Construction tools include mixer, impact drill, drill bit, cutting machine, trolley, shovel, flat screwdriver, serrated screwdriver, aluminum alloy scraper, etc. Construction materials such as rock wool board, adhesive, steel mesh, anchor bolt and plastering mortar shall be placed in a dry, clean and easy construction site selected in advance after mobilization. Construction openings and air conditioning openings shall be reserved for the enclosure of the building. If the ambient temperature is below 5 ℃, the wind force exceeds 5 or rainy days, the thermal insulation construction of rock wool board exterior wall is not allowed. After the mobilization of construction materials, installation of mechanical equipment, installation of protective facilities and technical disclosure are completed, the thermal insulation construction of rock wool board exterior wall can be carried out.
基層墻體處理
Base course wall treatment
為完成后續(xù)施工，保證工程質(zhì)量，必須確?；鶎訅w表面潔凈，不能有灰塵、油污、脫模劑等；確保墻面平整，不平整位置用水泥砂漿找平或者用角磨機(jī)打磨平整?；鶎訅w表面不能太干燥，干燥時應(yīng)灑水使之濕潤。采用防水砂漿進(jìn)行基層找平時，對于不同材料的墻面交界位置，可采用熱鍍鋅電焊網(wǎng)覆蓋，將電焊網(wǎng)壓入砂漿中，固定錨栓。找平層的表面須平整，立面須垂直，陰陽角方正度≤4mm。
In order to complete the follow-up construction and ensure the project quality, it is necessary to ensure that the surface of the base wall is clean and free of dust, oil stain, release agent, etc; Ensure that the wall is flat, and the uneven position is leveled with cement mortar or polished with an angle grinder. The surface of the base course wall should not be too dry, and should be watered when dry. The waterproof mortar is used for leveling the base course. For the junction position of the wall of different materials, the hot-dip galvanized welding mesh can be used to cover, press the welding mesh into the mortar, and fix the anchor bolt. The surface of the leveling layer must be flat, the elevation must be vertical, and the squareness of the internal and external corners ≤ 4mm.
墻面彈線
Snap line on the wall
施工前完成技術(shù)交底，讀懂圖紙細(xì)節(jié)，做好所有檐子造型，根據(jù)圖紙要求彈出水平基準(zhǔn)線，根據(jù)水平基準(zhǔn)線貼保溫板。在外墻表面讀取水平和垂直尺寸，使用手動式劃線器做好控制點標(biāo)識。固定吊頂彈線，用墨斗彈出水平控制線和垂直控制線。
Complete the technical disclosure before construction, read the details of the drawing, do a good job of all eaves modeling, snap the horizontal reference line according to the requirements of the drawing, and stick the insulation board according to the horizontal reference line. Read the horizontal and vertical dimensions on the exterior wall surface, and use the manual scriber to mark the control points. Fix the ceiling snapping line, and use the ink bucket to snap the horizontal control line and vertical control line.
掛基準(zhǔn)線
Hanging datum line
在建筑物的外墻位置，如陰角、陽角、飄窗邊沿、陽臺邊沿、平窗的窗套和其他技術(shù)圖紙要求的位置要外掛垂直基準(zhǔn)線。所有樓層在適當(dāng)位置掛設(shè)水平基準(zhǔn)線，用于控制巖棉板水平垂直。在保溫系統(tǒng)的一排巖棉板下方，散水標(biāo)高為100mm之處，用墨線彈出水平控制線。該位置需要選用防水性能好的保溫材料完成保溫施工，如擠塑聚苯板、可發(fā)性聚苯乙烯板或者硬發(fā)泡聚氨酯板等。
The vertical reference line shall be hung at the external wall of the building, such as the internal corner, external corner, the edge of the floating window, the edge of the balcony, the window cover of the flat window and other positions required by the technical drawings. All floors shall be hung with horizontal reference lines at appropriate positions to control the horizontal and vertical of rock wool board. Under a row of rock wool boards in the thermal insulation system, the horizontal control line is snapped with ink line at the apron elevation of 100mm. At this location, thermal insulation materials with good waterproof performance should be selected to complete the thermal insulation construction, such as extruded polystyrene board, expandable polystyrene board or rigid foam polyurethane board.
粘貼巖棉板
Paste rock wool board
巖棉板尺寸允許誤差在1.5mm以內(nèi)。先完成網(wǎng)格布翻包，在門窗洞口和變形縫兩側(cè)粘貼網(wǎng)格布，總寬度在200mm左右，翻包位置的寬度在80mm左右。網(wǎng)格布裁剪長度為板厚度加180mm。在網(wǎng)格布翻包部位涂抹專用粘結(jié)劑，涂抹范圍長為80mm，寬為2mm。壓入涂抹了專用粘結(jié)劑的網(wǎng)格布，其他部分甩出，掛設(shè)在旁邊備用。在巖棉板背面滿涂專用粘結(jié)劑，粘結(jié)劑厚度在3mm內(nèi)，粘結(jié)后檢查是否牢靠。
The allowable error of rock wool board size is within 1.5mm. First, complete the turn-over of the grid cloth, and paste the grid cloth on both sides of the door and window opening and the deformation joint, with the total width of about 200mm, and the width of the turn-over position of about 80mm. The cutting length of grid cloth is the plate thickness plus 180mm. Apply the special adhesive on the turn-over part of the mesh cloth, with a length of 80mm and a width of 2mm. Press in the mesh cloth coated with special adhesive, throw out the other parts and hang them aside for standby. Apply the special adhesive on the back of the rock wool board, the thickness of the adhesive is within 3mm, and check whether it is firm after bonding.
