Description

一种钢筋桁架楼承板的支撑结构A kind of support structure of steel truss floor deck

技术领域technical field

本发明涉及建筑技术领域，特别是指一种钢筋桁架楼承板的支撑结构。The invention relates to the technical field of construction, in particular to a support structure for a steel truss floor deck.

背景技术Background technique

以钢筋为上弦、下弦及腹杆，通过电阻点焊连接而成的桁架叫做钢筋桁架。钢筋桁架与底板连接固定形成整体的组合承重板叫做钢筋桁架楼承板。目前，以钢结构为主体的钢筋桁架楼承板在大跨度建筑及超高层建筑中运用较多，而此类建筑物施工过程中危险性较大且工期要求较高。便捷安全的施工措施不仅可以保证作业人员的人身安全，也可以提高作业效率。根据设计及规范要求，当进行长跨度楼承板浇筑时，需要在楼承板下方设置支撑结构，以避免底板的长边中部向下凹陷甚至造成坍塌。A truss connected by resistance spot welding with steel bars as the upper chord, lower chord and web member is called a steel bar truss. The combined bearing plate in which the steel truss and the bottom plate are connected and fixed to form a whole is called a steel truss floor bearing plate. At present, reinforced truss floor slabs with steel structure as the main body are used more in long-span buildings and super high-rise buildings, and the construction process of such buildings is more dangerous and requires higher construction period. Convenient and safe construction measures can not only ensure the personal safety of operators, but also improve work efficiency. According to the design and specification requirements, when the long-span floor deck is poured, it is necessary to set up a support structure under the floor deck to prevent the middle of the long side of the bottom plate from sinking downward or even causing collapse.

如附图1所示，现有一种支撑结构是采用钢管支撑架+托梁体系，楼承板1’两端架设在钢梁3’上，在楼承板1’下部设置钢管支撑架2’，并通过上部加设托梁4’作为临时支撑体系。该结构的缺点在于：①钢管支撑架底部需要平坦的板面，因此必须等到下方的楼承板浇筑完成并达到一定强度后方可使用，施工周期将大大加长，无法实现立体施工，楼层越高的建筑施工越慢；②临时支撑体系拆卸繁琐，耗用时间长；③钢管支撑架投入使用后周转周期较长，投入量较大。As shown in Figure 1, an existing support structure adopts a steel pipe support frame + joist system. , and add joists 4' to the upper part as a temporary support system. The disadvantages of this structure are: 1. The bottom of the steel pipe support frame needs a flat surface, so it must wait until the floor deck below is poured and reaches a certain strength before it can be used. The construction period will be greatly lengthened, and three-dimensional construction cannot be achieved. The slower the construction; ② the dismantling of the temporary support system is cumbersome and time-consuming; ③ the steel pipe support frame is put into use with a longer turnover period and a larger investment.
