When floor steel deckis only bent according to the span, the steel floor steel deckcan be connected with the steel beam, because the bottom of the slab is smooth, and there is enough joint area with the steel beam. Therefore, no treatment can be directly laid in the past (to avoid opening floor steel deckand steel beam and a virtual cut patch);

　　The composite floor slab of the closed platform can reduce the thickness of the floor and increase the clearance height. With an open bearing board, the minimum thickness required 126mm, and the use of the plate, minimum 104mm;

　　The building floor steel deckreplaces the traditional formwork and improves the shortcomings of the traditional formwork;

　　The floor steel deck floor steel deckreplaces the lower steel bar completely, and reduces the quantity of the steel reinforcement on the spot, thereby reducing the labor quantity on the spot and speeding up the construction speed. At the same time, the original design of lower reinforcement can provide more space for laying wires and wires in the floor;

　　The floor floor steel deckis simple, quick and easy to assemble;

　　The opening floor floor steel deckshall block the floor steel deckat the port so as to avoid pouring the concrete into thefloor steel deck the bottom of the plate, and the end floor steel deckis closed without the end blocking plate;

　　随着国内建筑产业的飞速发展以及建筑材料的日新月异,钢筋桁架楼承板也应运而生,在近几年的大型钢构项目中被广泛采用。本篇简要介绍钢筋桁架楼承板材料的性能及优点,并结合工程案例重点阐述钢构厂房中钢筋桁架楼承板施工的控制重点。                                               

　　楼承板(钢承板，建筑压型钢板)是采用镀锌钢板经辊压冷弯成型，其截面成V型、U型、梯形或类似这几种形状的波形，主要用作永久性模板，也可被选为其他用途。 

　　常用厚度:0.8mm 0.9mm 1.0mm 1.2mm 

　　型号:YX75-230-690 YX75-200-600 YX51-305-915 YX51-240-720 

　　YX76-305-915 YX76-344-688 YX51-250-750 YX75-200-800 

　　l 1、楼承板作为浇筑砼的模板，节省大量临时性模板，省去了模板支撑； 

　　l 2、楼承板堆放、运输、安装方便，减少施工工作量、改善工人施工条件； 

　　l 3、焊钉穿透楼承板焊接在钢梁上翼缘后楼承板可对钢梁起侧向支撑作用 

　　l 4、便于敷设通信、供电、采暖管线； 

　　l 5、楼承板作为模板直接支承于钢梁上，可以为各种工种提供宽敞的工作平台，因此浇筑砼及其他工种均可多层立体作业，可明显缩短工期
