建筑外墙保温结构 Building exterior wall insulation structure

技术领域: Technical field:

本实用新型涉及一种建筑物外墙的保温隔热结构。The utility model relates to a thermal insulation structure for the outer wall of a building.

背景技术: Background technique:

现在为了使建筑物更加节能,许多建筑的外墙上都需要设置保温结构,防止热量传递。通常的保温结构是在建筑外墙上多次手工涂抹上聚合物颗粒形成保温层,再在保温层表面涂抹上抗裂层,但是这种多次现浇施工形成的保温层不均匀,容易产生裂缝,保温效果不可靠,抗裂层和保温层的结合牢固度也较差,整体保温结构的施工效率低,增加了工期,综合造价高。并且,许多建筑物会在抗裂层表面再增加石材等装饰层,而保温结构的整体强度及承载力很差,在装饰层施工中非常容易破损,会限制建筑物的外墙装饰选择,使建筑保温结构的推广也受到影响。Now in order to make buildings more energy-efficient, many buildings need to be provided with thermal insulation structures on the exterior walls to prevent heat transfer. The usual thermal insulation structure is to manually smear polymer particles on the outer wall of the building to form an insulation layer, and then apply an anti-crack layer on the surface of the insulation layer. However, the insulation layer formed by this multiple cast-in-place construction is uneven and prone to Cracks, unreliable thermal insulation effect, poor combination of anti-crack layer and thermal insulation layer, low construction efficiency of the overall thermal insulation structure, increased construction period, and high overall cost. Moreover, many buildings will add decorative layers such as stone materials on the surface of the anti-crack layer, but the overall strength and bearing capacity of the thermal insulation structure are very poor, and it is very easy to be damaged during the construction of the decorative layer, which will limit the choice of exterior wall decoration of the building. The promotion of building insulation structures has also been affected.

实施例1:如图1和图2所示,保温层1设在外墙4的表面,保温层1表面则设有抗裂层2,在保温层1和抗裂层2之间还设有网状的钢丝层3,且钢丝层3通过膨胀螺栓5固定连接在外墙4上。保温层1采用聚合物颗粒,一般是聚苯颗粒混合胶液浆料制成,三厘米左右的厚度已能够较好隔热。本实施例的聚苯保温层1经检测,导热系数为0.054w/m.k,小于国标值的0.06w/m.k,保温性能更好。钢丝层3一般可用0.5毫米左右的钢丝网,抗裂层2一般则可以用玻纤或布纤水泥砂浆,涂抹三毫米左右即可。抗裂层2为高强度结构层,一般材料配比为玻纤或布纤∶水泥∶砂:=1∶100∶160,而水灰比为0.35,抗压强度≥40MPa,抗拉强度≥3.5Mpa。Embodiment 1: As shown in Figure 1 and Figure 2, the insulation layer 1 is arranged on the surface of the outer wall 4, and the surface of the insulation layer 1 is provided with an anti-crack layer 2, and a mesh is also arranged between the insulation layer 1 and the anti-crack layer 2. Shaped steel wire layer 3, and the steel wire layer 3 is fixedly connected to the outer wall 4 by expansion bolts 5. The insulation layer 1 is made of polymer particles, generally polystyrene particles mixed with glue slurry, and the thickness of about three centimeters can better insulate heat. The polystyrene insulation layer 1 of this embodiment is tested and found to have a thermal conductivity of 0.054w/m.k, which is less than the national standard value of 0.06w/m.k, and has better thermal insulation performance. The steel wire layer 3 generally can use the steel wire mesh of about 0.5 millimeter, and the anti-crack layer 2 can generally use glass fiber or cloth fiber cement mortar, smear about 3 millimeters and get final product. Anti-cracking layer 2 is a high-strength structural layer, the general material ratio is glass fiber or cloth fiber: cement: sand: = 1:100:160, and the water-cement ratio is 0.35, compressive strength ≥ 40MPa, tensile strength ≥ 3.5 MPa.

本实施例在施工时采用现场制作,先将足够面积的钢丝层3通过垫块和膨胀螺栓5平行隔空固定连接在外墙4上,隔空距离在三厘米左右,然后可以将混合好的聚苯颗粒浆料用压力喷涂或手工涂抹的方式浇灌入钢丝层3和外墙4之间的空间,并填满凝固形成保温层1。再在钢丝层3连同保温层1表面涂抹玻纤或布纤水泥砂浆形成抗裂层2,即可完成对建筑外墙4的保温结构施工。根据需要,一般的外墙装饰层7则设在抗裂层2外表,可以使用石材、涂料等。This embodiment adopts on-site production during construction. First, the steel wire layer 3 with a sufficient area is fixedly connected to the outer wall 4 through spacers and expansion bolts 5 in parallel. The space distance is about three centimeters. Then the mixed poly The benzene particle slurry is poured into the space between the steel wire layer 3 and the outer wall 4 by pressure spraying or manual smearing, and is filled and solidified to form the insulation layer 1 . Then apply glass fiber or cloth fiber cement mortar on the steel wire layer 3 and the surface of the insulation layer 1 to form an anti-crack layer 2, and then the construction of the insulation structure of the building exterior wall 4 can be completed. According to needs, the general exterior wall decoration layer 7 is located on the surface of the anti-crack layer 2, and stone materials, paints, etc. can be used.

由于保温层1会热胀冷缩,一般保温层1、钢丝层3和抗裂层2组成的保温结构以长度、宽度均不超过20米为独立单元,如图3所示,各独立单元之间设有伸缩缝6,且伸缩缝6内填有弹性填料,弹性填料一般使用聚氨酯材料,能弹性伸缩,并且防水密封。Since the thermal insulation layer 1 will expand with heat and contract with cold, generally the thermal insulation structure composed of the thermal insulation layer 1, the steel wire layer 3 and the anti-crack layer 2 is an independent unit with a length and a width of no more than 20 meters, as shown in Figure 3. Expansion joints 6 are arranged between them, and elastic fillers are filled in the expansion joints 6, and the elastic fillers generally use polyurethane materials, which can elastically expand and contract, and are waterproof and sealed.

实施例2:如图4和图5所示,保温层1连同钢丝层3组成预制保温板的形式,在保温层1和外墙4之间还设有粘结层8。由于采用预制板形式,保温层1的均匀度和质量较可靠。施工时,可以将预制保温板通过粘接层8连接在外墙4表面,再用膨胀螺栓5将其固定,安装速度较快。Embodiment 2: As shown in FIG. 4 and FIG. 5 , the thermal insulation layer 1 and the steel wire layer 3 form a prefabricated thermal insulation board, and an adhesive layer 8 is also provided between the thermal insulation layer 1 and the outer wall 4 . Due to the use of prefabricated panels, the uniformity and quality of the insulation layer 1 are relatively reliable. During construction, the prefabricated insulation board can be connected to the surface of the outer wall 4 through the adhesive layer 8, and then fixed with the expansion bolt 5, and the installation speed is fast.

预制保温板每块的面积不大,如图6和图7所示,一般各预制保温板表面的钢丝层3边缘通过钢丝网9相搭接,保温层1边缘之间则填充胶液泥浆,且各预制保温板搭接构成的独立单元的长度、宽度也均不超过20米,这样可以组成较大的面积,并保证整体强度。多个预制保温板搭接成的独立单元之间也需要伸缩缝6,处理同实施例1。同样,在形成抗裂层2后,也可根据需要施工设置装饰层7。The area of each prefabricated insulation board is not large, as shown in Figure 6 and Figure 7, generally the edges of the steel wire layer 3 on the surface of each prefabricated insulation board are overlapped by a steel wire mesh 9, and glue liquid mud is filled between the edges of the insulation layer 1. Moreover, the length and width of the independent units formed by the overlap of prefabricated insulation boards are not more than 20 meters, which can form a larger area and ensure the overall strength. Expansion joints 6 are also required between independent units formed by lapping of multiple prefabricated insulation boards, and the treatment is the same as in Embodiment 1. Similarly, after the anti-crack layer 2 is formed, the decorative layer 7 can also be constructed and provided as required.
