外墻保溫的做法及其優缺點

时间:2015-12-11     作者:華東公司【原创】   阅读

1.外墻保溫形式單一材料保溫外墻:加氣混凝土、燒結保溫磚復合保溫外墻:
The form of a single material of external wall insulation of exterior wall thermal insulation: 1 aerated concrete, sintering brick insulation composite insulation wall:
按照保溫材料設置位置的不同,可分為內保溫、外保溫和夾心保溫外墻。 保溫裝飾一體化板材其他:保溫砌塊等2.外墻內保溫技術墻內保溫是將保溫材料置于外墻體的內側。
According to the thermal insulation material is arranged in different position, can be divided into internal insulation, heat preservation and insulation sandwich wall. Thermal insulation and decoration integrated plate other: thermal insulation block 2 wall insulation technology in wall insulation is arranged in the outer wall thermal insulation material on the inner side of the.
優點:
Advantages:
1)對飾面和保溫材料的防水、耐候性等技術指標的要求不甚高,紙面石膏板、石膏抹面砂漿等均可滿足使用要求,取材方便;
1) waterproof, weather resistance and other technical indicators to cover and heat preservation material requirements are not very high, gypsum board, gypsum plaster mortar can meet the use requirement, convenient;
2)內保溫材料被樓板所分隔,僅在一個層高范圍內施工,不需搭設腳手架;
2) internal insulation materials are separated by a floor, the construction in only one storey range, without scaffold;
3)在夏熱冬冷和夏熱冬暖地區,內保溫可以滿足要求;
3) in hot summer and cold winter and hot summer and warm winter area, internal insulation can meet the requirements of;
4)對于既有建筑的節能改造,特別是目前當房屋賣給個人后,整棟樓或整個小區統一改造有困難時,只有采用內保溫的可能性大一些。因此,近幾年,外墻內保溫也得到廣泛的應用。
4) to transform both energy-efficient construction, especially at present when the housing sold to individuals, there are difficulties in the whole building or the whole area of unified transformation, only the use of thermal insulation in the possibility of some. Therefore, in recent years, external wall insulation is widely used.
缺點:
Disadvantages:
1)由于圈梁、樓板、構造柱等會引起熱橋,熱損失較大;
1) because the ring beam, floor, structural column will cause the bridge, more heat loss;
2)由于材料、構造、施工等原因,飾面層出現開裂;
2) due to the material, structure, construction and other reasons, the decorative layer cracking;
3)不便于用戶二次裝修和吊掛飾物;
3) for user two decoration and jewelry;
4)占用室內使用空間;
4) occupy the indoor use of space;
5)對既有建筑進行節能改造時,對居民的日常生活干擾較大。
5) of the existing building energy-saving renovation, the daily life of residents disturbed.
6)墻體受室外氣候影響大,晝夜溫差和冬夏溫差大,容易造成墻體開裂。
6) the wall by the outdoor climate, the temperature difference between day and night and summer and winter temperature difference is big, easy to cause the wall cracking.
3.外墻夾心保溫技術外墻夾心保溫是將保溫材料置于外墻的內、外側墻片之間,內、外側墻片可采用混凝土空心砌塊。
3 exterior wall heat insulation technology of external wall thermal insulation sandwich sandwich thermal insulation material is arranged in the outer wall is inside, outside wall, lateral wall in between, can adopt hollow concrete block.
優點:
Advantages:
1)對內側墻片和保溫材料形成有效的保護,對保溫材料的選材要求不高,聚苯乙烯、玻璃棉以及脲醛現場澆注材料等均可使用;
1) the formation of the effective protection of the medial wall and insulation materials, the selection of insulation material requirements is not high, polystyrene, glass wool and UF site casting materials can be used;
2)對施工季節和施工條件的要求不十分高,不影響冬期施工。在黑龍江、內蒙古、甘肅北部等嚴寒地區曾經得到一定的應用。
2) on the construction season construction conditions and requirements are not very high, does not affect the construction in winter. Once a certain application in severe cold area of Heilongjiang, Inner Mongolia, north of Gansu.
缺點 :
Disadvantages:
1)在非嚴寒地區,此類墻體與傳統墻體相比尚偏厚;
1) the cold regions in the non, such wall and wall is thick compared to traditional;
2)內、外側墻片之間需有連接件連接,構造較傳統墻體復雜;
2) connector between the inner lateral walls, need, compared with the traditional wall complex structure;
3)外圍護結構的“熱橋”較多。在地震區,建筑中圈梁和構造柱的設置,“熱橋”更多,保溫材料的效率仍然得不到充分的發揮。
3) the peripheral structure of "thermal bridge" more. In the earthquake zone, building the circle beam and structural column settings, "bridge" more efficient thermal insulation material, still not get into full play.
4)外側墻片受室外氣候影響大,晝夜溫差和冬夏溫差大,容易造成墻體開裂和雨水滲漏
The 4 lateral walls) by the outdoor climate, the temperature difference between day and night and summer and winter temperature difference is big, easy to cause the wall cracking and water leakage
