The application discloses a prestressed steel pipe truss anti overlapping composite plate, which relates to the technical field of laminated plates and weight reducing blocks, in order to reduce the incremental cost brought by prefabricated buildings. The steel pipe truss comprises a steel pipe truss and a base plate, the steel pipe truss is arranged inside the base plate, the steel pipe truss also comprises a connecting block, a first fixed pipe and a weight reducing block, the left and right sides of the connecting block are welded with a lower chord reinforcement, the top of the lower chord reinforcement is welded with a second fixed pipe, the first fixed pipe is fixedly installed inside the first fixed pipe, and the second fixed pipe is internally provided with a web bar reinforcement, An upper chord reinforcement is welded between the two web member reinforcements, and a weight reducing block is prefabricated between the truss and the truss. Compared with the laminated plate in the prior art, the application is generally composed of a large number of bottom chord reinforcement in a cross structure, and its own weight is high. However, the steel pipe truss adopted by the utility model is composed of connecting blocks and vertical bottom chord reinforcement, which greatly reduces the overall weight of the floor slab. The web member reinforcement is fixed with the bottom chord reinforcement through the second fixed pipe to prevent displacement during the pouring process. Prevent displacement during pouring. Prevent displacement during pouring< br/>

一种预应力钢管桁架减重叠合板
[0001]本申请涉及叠合板的
,尤其是涉及一种预应力钢管桁架减重叠合板。
技术介绍
[0002]叠合楼板是由预应力板和现浇钢筋混凝土层叠合而成的装配整体式楼板。预应力叠合板板整体性好,板的上下表面平整,便于饰面层装修,密拼工法,免模免撑,适用于大跨度、大荷载的框架建筑,叠合楼板的一组成部分是现浇混凝土层,其厚度因楼板的跨度大小而异,但至少应与预制薄板的厚度相等。随着跨度的增大,往往在现浇混凝土层内填以聚苯乙烯泡沫或PPE 塑料箱体;箱体铺在预制薄板韵上都,形成一个籍黪断面,以减轻现浇混凝土的重量并可作为叠合楼板的保温隔音层。由于在现浇混凝土层内配置了负钢筋,形成了一些峰间支点,使箱形断面成为连续结构。现浇层内另按缝构、防火等要求,镰设钢筋并铺设备种管线。
[0003]现有技术中的叠合板一般重量较重,在日常使用中当需要大量叠合板组合时,容易使其断裂。
技术实现思路
[0004]为了降低叠合板的重量,本申请提供一种预应力钢管桁架减重叠合板。
