Translated fromChinese技术领域technical field
本实用新型涉及格构式塔吊基础辅助设备技术领域，具体涉及一种可周转单元化的格构式塔吊基础上人装置。The utility model relates to the technical field of lattice type tower crane foundation auxiliary equipment, in particular to a turnover unitized lattice type tower crane foundation climbing device.
背景技术Background technique
格构式塔吊基础主要由预埋于灌注桩内的钢格构柱及在其上浇筑的钢筋混凝土承台或焊接钢板组成，以此作为承受塔吊荷载的基础。这种结构形式在深基坑工程运用中相对于传统方式(例如：①开挖塔吊基础土方，将塔吊基础作用在地下室底板处；②利用混凝土桩作为塔吊基础)具有以下优点：施工方法简便，相对工期较短，质量安全有保证；格构柱材料可回收，成本相对较低的特点。因此，目前在较大深基坑地下室施工过程中，更多地采用格构式塔吊基础作为现场塔吊的基础形式。The lattice tower crane foundation is mainly composed of steel lattice columns pre-buried in cast-in-place piles and reinforced concrete caps or welded steel plates poured on them, as the basis for bearing the tower crane load. Compared with traditional methods in the application of deep foundation pit engineering (for example: ① excavating the earthwork of the tower crane foundation, and applying the tower crane foundation to the basement floor; ② using concrete piles as the tower crane foundation), it has the following advantages: the construction method is simple, Relatively short construction period, quality and safety are guaranteed; lattice column material can be recycled, and the cost is relatively low. Therefore, at present, in the construction process of large deep foundation pit basement, the lattice tower crane foundation is more used as the foundation form of the on-site tower crane.
在深基坑地下室结构施工过程中，若采用格构式塔吊基础，塔吊操作人员需从地下室开挖面采用上人装置，上至塔基混凝土承台，进而到达塔吊操作室。现有的上人装置通常采用钢管搭设上人马镫或爬梯，由于其为临时搭设装置，安全性与灵活性较差；且在进行下一标高楼层作业时，还需要将整个架体拆除，吊装完成需再次安装上人装置，施工工艺较为繁琐，反复拆搭耗时耗力，成本投入较大。因此，一种可周转、施工简便、更加安全与经济的格构式塔吊基础专用上人装置亟待开发。In the construction process of the basement structure of the deep foundation pit, if the lattice tower crane foundation is used, the tower crane operator needs to use the upper device from the basement excavation surface, up to the tower foundation concrete bearing platform, and then to the tower crane operation room. The existing climbing devices usually use steel pipes to set up stirrups or climbing ladders. Because they are temporary devices, the safety and flexibility are poor; and when the operation on the next elevation floor is carried out, the entire frame body needs to be dismantled and hoisted. After the completion, it is necessary to re-install the upper-hand device, the construction process is relatively cumbersome, the repeated dismantling and erection are time-consuming and labor-intensive, and the cost investment is relatively large. Therefore, there is an urgent need to develop a special access device for lattice tower crane foundations, which can be turned around, is easy to construct, and is safer and more economical.
