復合板質量控制的措施及建議

來源:http://www.babyflay.com/ 日期:2022-02-14 發布人:jiangucaigang
以巖棉復合板為例,保溫材料巖棉板要求:選用阻燃板,密度為≥140kg/m3,導熱系數≤0.04w/m.k,垂直于外表的抗拉強度≥10KPA,抗壓強度≥40kpa,燃燒功能等級為a級。
Taking rock wool composite board as an example, the requirements for rock wool board as thermal insulation material: select flame-retardant board, the density is ≥ 140kg / m3, the thermal conductivity is ≤ 0.04w / m.k, the tensile strength perpendicular to the surface is ≥ 10KPA, the compressive strength is ≥ 40kpa, and the combustion function grade is Grade A.
優選玻璃纖維網布:煙臺保溫板薄抹灰外墻外保溫體系中運用的玻璃纖維網布,由于埋在水泥砂漿中,要求耐堿。根據數據,煙臺聚苯板外墻保溫體系可到達40-50年的運用壽命。如果運用耐堿玻璃纖維網格布,它將在水泥的堿性環境中提前破壞破碎,這將大大縮短整個體系的運用壽命。因而,有必要選用耐堿玻璃纖維網格布。
Glass fiber mesh is preferred: the glass fiber mesh used in Yantai insulation board thin plastering external wall external insulation system is required to be alkali resistant because it is buried in cement mortar. According to the data, Yantai polystyrene board exterior wall insulation system can reach the service life of 40-50 years. If the alkali resistant glass fiber mesh cloth is used, it will be damaged and broken in advance in the alkaline environment of cement, which will greatly shorten the service life of the whole system. Therefore, it is necessary to choose alkali resistant glass fiber mesh cloth.
粘結砂漿的挑選:由于現場摻入水泥,施工進程中難以操控水泥的質量和配比,增加了施工進程的復雜性。單組分粘結砂漿施工簡略。只能通過加水和現場拌和的方法運用,以防止因水泥等資料增加不當而導致粘結砂漿質量下降。施工時盡量選用單組分粘結砂漿。
Selection of bonding mortar: due to the addition of cement on site, it is difficult to control the quality and proportion of cement in the construction process, which increases the complexity of the construction process. Construction of single component bonding mortar is simple. It can only be used by adding water and on-site mixing, so as to prevent the decline of bonding mortar quality due to improper addition of cement and other materials. Single component bonding mortar shall be selected as far as possible during construction.
挑選錨固件:挑選錨固件后,有必要首要進行錨固件的樣品施工和拉伸試驗。
Selection of anchors: after the selection of anchors, it is necessary to first carry out the sample construction and tensile test of anchors.
2、材料應合理寄存
2. Materials shall be properly deposited
做好施工前的準備工作,做好倉庫管理工作。在許多施工現場,常見的是巖棉板進入現場后露天堆積。巖棉板的日曬雨淋非常容易引起板結構變形和收縮變形。
Make preparations before construction and warehouse management. In many construction sites, it is common for rock wool boards to accumulate in the open air after entering the site. The sun and rain of rock wool board are very easy to cause board structure deformation and shrinkage deformation.
3、基層處理有必要合格
3. The treatment of base course must be qualified
對于外保溫工程(特別是抹灰層較薄的外保溫體系),抹灰層與飾面層之間的尺度誤差在很大程度上取決于基層。因而,施工前有必要對基層的尺度誤差進行評定。
For external insulation works (especially the external insulation system with thin plastering layer), the scale error between plastering layer and finishing layer largely depends on the base course. Therefore, it is necessary to evaluate the scale error of the base before construction.
4、現場膏體按比例配制
4. The on-site paste is prepared in proportion
粘結料漿在外墻保溫巖棉板施工中起著重要作用。比例有必要嚴厲按照闡明執行,并留意及時性。
Binder slurry plays an important role in the construction of external wall thermal insulation rock wool board. It is necessary to strictly follow the instructions and pay attention to timeliness.
5.巖棉復合板資料尺度的挑選有必要標準合理
5. The selection of data scale of rock wool composite board is necessary and the standard is reasonable
6.正確結構玻璃纖維網布
6. Glass fiber mesh with correct structure
鋪貼網格布壓入膠結層,外表抗裂砂漿應充沛刮平網格布,但厚度不宜過厚。對于抹灰層較薄的體系,保護層的厚度應不小于3mm,且不大于6mm,以隱藏的網格為準,以充沛發揮網格布反抗溫度引起的應力。如果抗裂砂漿太厚,格柵布就不能起到很好的作用,簡單造成外表裂縫。門窗洞口及陰陽角四周加鋼筋網,一層墻面滿鋪一層鋼筋網。
The grid cloth shall be paved and pressed into the cementation layer, and the anti crack mortar on the surface shall fully scrape the grid cloth, but the thickness shall not be too thick. For the system with thin plastering layer, the thickness of the protective layer shall not be less than 3mm and not more than 6mm, subject to the hidden grid, so as to give full play to the stress caused by temperature. If the anti crack mortar is too thick, the grid cloth can not play a good role and simply cause surface cracks. Reinforcement mesh shall be added around door and window openings and internal and external corners, and a layer of reinforcement mesh shall be fully paved on the wall on the first floor.
7.建議選用條狀粘結法粘貼巖棉板
7. It is recommended to use strip bonding method to paste rock wool board
所謂條狀粘結法是將砂漿攤鋪在整個板材上,然后用鋸齒抹子將其攤鋪,并將多余的砂漿掛起。該方法施工在處理平整的墻體上,可防止空鼓的發生,不會產生巖棉板的翹曲變形,也可防止因封邊不嚴而滲水、通風、掉落。條帶粘結法消耗的砂漿與點粘結法消耗的砂漿幾乎相同。
The so-called strip bonding method is to spread the mortar on the whole plate, then spread it with a serrated trowel, and hang the excess mortar. This method can prevent hollowing and warping deformation of rock wool board, and can also prevent water seepage, ventilation and falling due to lax edge sealing. The mortar consumed by strip bonding method is almost the same as that consumed by point bonding method.
8.防止外表砂漿裂縫應留意的問題
8. Problems needing attention to prevent surface mortar cracks
外表抹灰砂漿抹兩遍,總厚度操控在3mm~6mm之間。
The surface shall be plastered with mortar twice, and the total thickness shall be controlled between 3mm and 6mm.
