一、橡胶止水条简单介绍 橡胶止水条是采用一种既有橡胶制品特性, 又有遇水自行膨胀以止水的功能。 广泛应用于人 防、地铁、隧道、污水处理工程、游泳池等以及其他混凝土工程施工缝、伸缩缝、裂缝。

　　First, rubber sealing strip is a brief introduction to rubber water stop strip, which is characterized by both rubber products and water swelling. Widely used in civil air defense, subway, tunnel, sewage treatment works, swimming pools, and other concrete construction joints, expansion joints, cracks.

　　二、橡胶止水条的分类

　　Two. Classification of rubber stop strip

　　1.腻子型止水条 腻子型遇水膨胀止水条是近期研制的新产品, 它具有遇水膨胀的特殊性能。具有弹性接缝止 水材料的密封防水作用, 当接缝两面侧距离加大到弹性防水材料的弹性复原率以外时, 由于 该材料具有遇水膨胀的特性。在材料膨胀范围以内仍然能起止水作用。

　　1., putty type waterproof strip, putty type water expansion water stop strip is a new product developed recently, it has the special properties of water swelling. The waterproof effect of elastic joint waterproof material, when the distance between the two sides of the joint increases to the elastic recovery rate of the elastic waterproof material, because the material has the characteristics of water swelling. It can still stop water within the range of material expansion.

　　2.制品性止水条 制品型遇水膨胀橡胶止水条它具有吸水后膨胀率高,加压不失水,与空气接触不风化,耐酸 碱性稳定,抗老化等优点。该产品主要应用于盾构施工法现砌接缝防水,建筑物变形缝、施 工缝用止水带以及金属、混凝土等各类预制构件接缝防水。

　　2. product water stop strip type water expansion rubber water stop strip, it has high expansion rate after water absorption, pressure does not lose water, contact with air is not weathering, acid and alkali stability, anti-aging and other advantages. The product is mainly used in the shield construction method of waterproof joint, the building deformation joints, construction joints with water stop and metal, concrete and other prefabricated joint waterproof.

　　3.自粘性胶条 自粘性胶条是由丁基橡胶填充挤增塑剂及其它特种助剂, 经过特殊工艺加工而成的一种新型橡胶防水材料。它不仅填充砼土气孔缝隙,而且在一定压力下,与混凝土有良好的粘结力, 使其与混凝土联为一体,起到防水止水的作用。

　　3. self adhesive adhesive tape self adhesive strip is filled with butyl rubber, extrusion plasticizer and other special additives, a new type of rubber waterproof material processed by special process. It not only fills the pore gap of concrete soil, but also has good bonding force with concrete under certain pressure, so that it can be combined with concrete to play the role of waterproof and sealing.

　　本产品具有良好的气密性,较好的粘接强度,极强的自粘性和变形性,可以不用粘接剂在 一定条件下与新浇混凝土直接粘接,克服过去止水材料因与混凝土界面粘接不牢引起的环绕 渗漏问题,具有良好的耐水性、耐酸碱性及耐老化性能,可广泛应用于水利、水电工程及各 类工民建工程。

　　This product has good air tightness, good bonding strength, self adhesive deformation and strong adhesive bonding, can not directly with fresh concrete under certain conditions, to overcome the past due to leakage of sealing material around the bonding interface between concrete and solid caused, has good water resistance, acid and alkali resistance the aging performance, can be widely used in civil engineering, water conservancy and Hydropower Engineering and all kinds of.

　　三、橡胶止水条的安装方法

　　Three. The installation method of rubber stop strip

　　1.在下一节混凝土浇筑前,已出现的纵(水平)向或横(环)向施工缝界面上均应安装止水条。

　　1. before the next section of concrete pouring, the longitudinal (horizontal) or transverse (ring) interface should be installed on the construction joints.

　　2.如何将止水条固定在当头板上,则要根据该框架的施工方法和机具设备能力来确定,可用 铁钉、螺栓或铁丝固定。总之其固定方法可由施工人员充分发挥其想象力,达到预留凹槽方 便、快捷、省料之目的。

　　2. how to fix the water stop strip on the head plate is determined according to the construction method and equipment capacity of the frame, and can be fixed with nails, bolts or wires. In short, its fixed method can give full play to its imagination by the construction staff, so as to achieve the purpose of convenient, quick and saving the reserved groove.

　　3.需粘贴固定止水条的施工缝,后浇缝的界面应保持干燥、平缝、施工前须清除界面上的浮 渣、尘土及杂物。

　　3. need to paste the fixed water stop construction joint, the interface of the pouring joint should be kept dry, flat seam, before construction, must clear the scum, dust and sundries on the interface.

　　4.橡胶止水条安装部位确定后,在需安装止水条的界面上和止水条的底面均涂上薄薄一层胶 粘剂,待胶液挥发一段时间后再进行粘贴,或用高强度锚钉将止水条固定在安装的部位。

　　4. rubber seal installation position is determined, the surface was coated with a thin layer of adhesive in the installation of the sealing of the interface and the sealing of the bottom, until the glue volatilized after a period of time and then paste, or with high strength anchor will seal in the parts of the fixed installation.

　　5.若遇混凝土界面潮湿或凹凸不平,胶粘剂粘贴固定不牢时,可视具体状况用高强度锚钉进 一步加强固定。总之,止水条必须与混凝土界面紧密接触固定牢实、防水止水条脱离界面而 失去抗渗的作用。

　　5. in case of concrete interface wet or uneven, adhesive paste is not firmly fixed, according to the actual situation with high strength anchor to further strengthen fixed. In short, water must be close contact with concrete interface, waterproof seal from the fixed solid interface and lost anti permeability role.
