Light partition boards need to be spliced during installation, but if there is no skill and experience in splicing, problems will occur after splicing. The common problem is uneven, or cracks, and there are large cracks on the wall, which will not only affect the normal use, but also greatly affect the beauty of the wall, Therefore, cracks must be avoided during the installation of light partition board, so how should they be avoided?

1、實際上輕質(zhì)隔墻板在進行拼接時多少都會有一些縫隙，但是安裝質(zhì)量好的情況下縫隙是非常小的，所以如果輕質(zhì)隔墻板出現(xiàn)損壞現(xiàn)象時，施工的墻體中縫隙可能會更大，所以這時候我們就有必要將其作為隔斷板進行封堵。

1. In fact, there will be some gaps in the light partition board during splicing, but the gap is very small when the installation quality is good. Therefore, if the light partition board is damaged, the gap in the construction wall may be larger, so it is necessary to block it as a partition board at this time.

2、對于地面不平整，或者是板長的制作誤差和梁、柱底面高度的模板誤差，這種情況下輕質(zhì)隔墻板的上下接縫一般在3-8厘米范圍內(nèi)，在接縫處可以用水泥砂漿、板頭、磚塊等硬物填充，使用水泥砂漿填充兩板連接處時必須飽滿、密實，還要擠出的多余砂漿并及時刮掉。另外換需要注意輕質(zhì)隔墻板邊調(diào)整處理槽必須在接縫處的水泥砂漿和墻板干透后抹灰時一起處理。

2. For the uneven ground, or the fabrication error of plate length and the formwork error of beam and column bottom height, in this case, the upper and lower joints of light partition board are generally within 3-8 cm. The joints can be filled with hard objects such as cement mortar, plate head and brick. When filling the joint of two plates with cement mortar, it must be full and dense, The excess mortar shall be extruded and scraped off in time. In addition, it should be noted that the light partition board edge adjustment treatment tank must be treated together with the cement mortar at the joint and plastering after the wall board is completely dry.

3、如果擔(dān)心水泥砂漿黏合力不夠的情況下，我們還可以采用聚合物黏結(jié)砂漿作為安裝嵌縫砂漿，這種砂漿具有很強的粘接力和較強的韌性，硬化時不收縮，用于輕質(zhì)建筑板材安裝時可以不落漿，保證嵌縫砂漿飽滿，增強嵌縫的粘接強度，抑制收縮應(yīng)力的破壞作用，嵌縫砂漿自身不收縮減少收縮應(yīng)力。

3. If we are worried that the adhesive force of cement mortar is not enough, we can also use polymer bonding mortar as the installation caulking mortar. This mortar has strong adhesive force and strong toughness, does not shrink when hardening, and does not fall when used for the installation of light building plates, so as to ensure that the caulking mortar is full, enhance the bonding strength of caulking and inhibit the destructive effect of shrinkage stress, The caulking mortar does not shrink and reduces the shrinkage stress.

4、另外輕質(zhì)隔墻發(fā)現(xiàn)在較長墻體施工安裝過程中，建議在安裝時每隔3～5米距離預(yù)留一處安裝縫暫時不做處理，讓此段墻體自由收縮7～10天，待收縮應(yīng)力已基本釋放、變形穩(wěn)定后再用聚合物嵌縫砂漿將此連續(xù)接縫填實。這樣可避免長墻累積收縮應(yīng)力過大造成縫隙。

4. In addition, it is found that during the construction and installation of the long wall, it is recommended to reserve an installation joint every 3 ~ 5m during installation, and do not deal with it temporarily, so that the wall can shrink freely for 7 ~ 10 days. After the shrinkage stress has been basically released and the deformation is stable, the continuous joint can be filled with polymer caulking mortar. This can avoid the gap caused by excessive accumulated shrinkage stress of long wall.

5、選材也是很重要的，在選用板材前，深入各板材生產(chǎn)企業(yè)進行考察，了解其生產(chǎn)工藝、質(zhì)量保證體系、材料臨時堆放場地，以保證板材各項指標(biāo)都符合國家標(biāo)準(zhǔn)、有足夠的板材晾曬時間、保證材料的干燥，就是保證安裝后正常使用的前提。

5. Material selection is also very important. Before selecting plates, go deep into various plate production enterprises to investigate and understand their production process, quality assurance system and temporary material stacking site, so as to ensure that all indexes of plates meet national standards, have sufficient plate drying time and ensure the drying of materials, which is the premise to ensure normal use after installation.

6、另外安裝輕質(zhì)隔墻板時，也會對門框造成影響，所以為避免門框上部倒八字裂縫，可在門框與長墻連接處，距門框兩塊板處預(yù)留一收縮縫暫不處理以釋放應(yīng)力，7～10天后再用聚合物水泥砂漿填實處理，遮陽就可以避免門框處出現(xiàn)縫隙。

6. In addition, the installation of light partition board will also affect the door frame. Therefore, in order to avoid the inverted splay crack on the upper part of the door frame, a shrinkage joint can be reserved at the connection between the door frame and the long wall and at the two plates away from the door frame, which will not be treated temporarily to release the stress. After 7 ~ 10 days, it can be filled with polymer cement mortar to avoid the gap at the door frame.

7、我們還要注意對輕質(zhì)隔墻板根部處理。在條板施工安裝完畢之后，派專人對立板根部檢查，并用砼達到終凝之后，再拔掉木楔填細(xì)石砼，這樣才能夠保證正常安全使用。

7. We should also pay attention to the root treatment of light partition board. After the strip construction and installation is completed, a special person shall be assigned to inspect the root of the opposite plate, and after the concrete reaches the final setting, the wooden wedge shall be pulled out and filled with fine aggregate concrete, so as to ensure normal and safe use.
