Construction method for large-span roof truss
The invention provides a construction method for a large-span roof truss. The construction method comprises the following steps that the position of a temporary supporting frame is determined; then the hoisting sequence and the hoisting route of each section of sectional hoisting piece are determined; a temporary supporting assembly is mounted on a floor structure steel beam; multiple pressure bearing pieces are mounted on the temporary supporting assembly; the multiple sections of sectional hoisting pieces and embedding rods are sequentially hoisted on the multiple pressure bearing pieces correspondingly, and are assembled in the high altitude; and after a truss structure is assembled, the temporary supporting assembly is disassembled, wherein the disassembling step comprises the following sub-steps that the pressure bearing pieces are cut off, the height of cutting off of each time is controlled according to the unloading displacement amount of the supporting position until the trussstructure does not generate the downward displacement after cutting off of a certain time is completed, and then the temporary supporting assembly is removed. According to the provided construction method for the large-span roof truss, the truss deflection is adjusted through a method of cutting off the pressure bearing pieces multiple times, so that slow movement of all the parts of the truss structure is facilitated, and the unloading precision can be quite conveniently controlled.
本发明提供了一种大跨度屋盖桁架施工方法，包括确定临时支撑架的位置；然后确定各段分段吊装件的吊装顺序以及吊装路线；将临时支撑组件安装在楼层结构钢梁上；在临时支撑组件上安装多个承压件；依次将多节分段吊装件和嵌补杆分别吊装在多个承压件上，并在高空中进行拼接；桁架结构拼装完成后，对临时支撑组件进行拆卸；拆卸步骤如下：对承压件进行割除，并根据支撑位置的卸载位移量控制每次割除的高度直至完成某一次的割除后桁架结构不再产生向下的位移；然后拆除临时支撑组件。本发明提供的一种大跨度屋盖桁架施工方法，对承压件采用多次割除的方法进行桁架挠度的调节，有利于桁架结构各部位缓慢的移动，能很方便的控制卸荷精度。
