A sealed end concrete heating and thermal insulation device is characterized in that the heating insulation body and support frame include a self limiting temperature point, a heat preservation layer and a waterproof layer, and a plurality of connecting rope bodies are arranged on the surface of the insulation layer, and the inner surface of the heat insulation layer is coiled on the inner surface of the insulation layer from the temperature limiting point, and is detachable by connecting the rope body. The supporting frame is supported on the heating insulation body, and the supporting frame is provided with right angle parts at the two ends. The end plate of the right angle part is provided with a threaded hole. The axial of the threaded hole is parallel to the heating insulation, and the screw hole is fitted with the thread connected top screw. The utility model can effectively improve the maintenance and heat preservation measures for the construction of the sealed end concrete during the winter construction, improve the working efficiency, and ensure that the temperature of the sealed end concrete is not less than 5 centigrade during the curing period, and the heating and thermal insulation device is immediately covered after the completion of the closed concrete construction.
【技术实现步骤摘要】
一种封端混凝土加热保温装置
本技术涉及加热保温装置,具体地说是一种应用于冬期梁体封端混凝土施工中的封端混凝土加热保温装置。
技术介绍
一般铁路梁场项目由于工期紧,任务重,需要进行冬期施工,而严寒的冬季气候远低于5℃,难以满足封端养护规范设计要求,由于早期混凝土强度上升缓慢,低温气候易造成封端混凝土开裂现象,难以保证施工质量,在严寒气候下,仅通过篷布、棉织物等覆盖方式进行保温养护难以满足封端养护规范设计要求。
技术实现思路
本技术的目的是为了弥补现有养护方式的不足,提供了一种封端混凝土加热保温装置,确保在预制梁封端施工后养护温度不低于5℃。本技术是通过以下技术方案来实现的:包括加热保温体和支撑架,所述加热保温体包括自限温点伴热带、保温层和防水层,所述保温层上表面排列有多个连接绳体,所述自限温点伴热带盘绕在保温层的内表面,并通过连接绳体可拆卸连接固定,所述自限温点伴热带的两端与插座的正负极连接;所述支撑架支撑在加热保温体四周,且所述支撑架对应两端设有直角件,所述直角件的末端板上设有螺纹孔,所述螺纹孔的轴向与加热保温体平行,所述螺纹孔配合有螺纹连接的顶紧螺杆。进一步,所述保温层包括第一保温层和第二保温层,所述第一保温层和第二保温层的内、外表面均设有连接绳体,所述自限温点伴热带盘绕在第一保温层的内表面,并通过连接绳体可拆卸连接固定,所述第二保温层通过绳体与第一保温层可拆卸连接固定,所述防水层内表面设有连接绳体,所述防水层通过连接绳体与第二保温层可拆卸连接。进一步,所述第一保温层为棉织物篷布材质,所述第二保温层为土工布材质。与已有技术相比,本技术有益效果体现在:本技术装置设 ...
