其具体安装方法是：The specific installation method is:
先在绑扎好钢筋的梁外墙一侧定位安装好预埋焊板2，然后对梁外墙浇筑结构混凝土，形成建筑物结构外围钢筋混凝土结构1，并在钢筋混凝土结构1的上层预留有能安装高强螺栓14的支撑孔，在所述预埋焊板2的一侧设有结构钢筋6，而在预埋焊板2的另一侧设有保险栓钢筋3和保险栓滑槽5，待浇筑的结构混凝土强度达到要求后；First position and install the pre-embedded welding plate 2 on one side of the beam outer wall where the steel bars are bound, and then pour structural concrete on the beam outer wall to form a reinforced concrete structure 1 around the building structure, and reserve a support hole for installing high-strength bolts 14 on the upper layer of the reinforced concrete structure 1. A structural steel bar 6 is provided on one side of the pre-embedded welding plate 2, and a safety bolt steel bar 3 and a safety bolt chute 5 are provided on the other side of the pre-embedded welding plate 2. After the strength of the structural concrete to be poured meets the requirements;
然后将焊接有悬挑工字钢4的工字钢焊板8插入到工字钢焊板槽7中，并在悬挑工字钢4中焊接有工字钢斜拉焊板10，同时在工字钢斜拉焊板10中通过拉杆下端焊板12连接有下拉螺杆13；而在钢筋混凝土结构1的上层所预留的支撑孔中安装高强螺栓14，所述高强螺栓14的两端通过高强螺帽16与钢筋混凝土结构1的侧面固定连接，同时在钢筋混凝土结构1的一侧面固定有拉杆上端焊板15，所述拉杆上端焊板15通过高强螺帽16固定于高强螺栓14中，并在所述拉杆上端焊板15的端部焊接有上拉螺杆17；所述下拉螺杆13和上拉螺杆17之间通过拉杆螺帽18与拉杆钢筋19相连接，使之形成稳定的斜拉三角形悬挑结构；Then the I-beam welding plate 8 that is welded with the cantilevered I-beam 4 is inserted into the I-beam welding plate groove 7, and the I-beam obliquely-stayed welding plate 10 is welded in the overhanging I-beam 4, and the pull-down screw 13 is connected with the lower end welding plate 12 of the pull rod in the I-beam obliquely-staying welding plate 10; The side of 1 is fixedly connected, and at the same time, one side of the reinforced concrete structure 1 is fixed with a tie rod upper end welding plate 15, which is fixed in a high strength bolt 14 through a high-strength nut 16, and a pull-up screw 17 is welded at the end of the pull-rod upper end weld plate 15; between the pull-down screw 13 and the pull-up screw 17 is connected with a pull-rod reinforcing bar 19 through a pull-rod nut 18, so that it forms a stable cable-stayed triangular cantilever structure;
最后通过拉杆螺帽18与拉杆钢筋19之间的配合，完成所述下拉螺杆13和上拉螺杆17的张拉后，再将保险栓钢筋3下调，使之与所述工字钢焊板8上端锁住后，即可在悬挑工字钢4上施工作业，搭设用于悬挑作业的脚手架。Finally, through the cooperation between the tie rod nut 18 and the tie rod steel bar 19, after the tensioning of the pull-down screw 13 and the pull-up screw 17 is completed, the safety bolt steel bar 3 is lowered to lock it with the upper end of the I-beam welding plate 8, and the construction work can be carried out on the cantilever I-beam 4, and a scaffold for the cantilever operation can be erected.
进一步地，本发明所述的安装方法，其中所述预埋焊板2设有能容纳所述工字钢焊板8的工字钢焊板槽7，在所述预埋焊板2的背部形成有板沟结构，所述结构钢筋6可挂接于板沟结构处，在所述述预埋焊板2中还形成有焊板槽，在所述焊板槽两侧设有用于检测悬挑工字钢4向下倾斜的程度的保险栓滑槽5及保险栓钢筋3；通过斜向上拉所述保险栓钢筋3，可将安装于钢筋混凝土结构1中的预埋焊板2整块取出，便于拆除悬挑工字钢4以及对预埋焊板2重复使用，并在后期外墙抹灰时可将预埋焊板2拆除时所形成凹槽抹平即可。Further, in the installation method of the present invention, wherein the embedded welding plate 2 is provided with an I-beam welding plate groove 7 capable of accommodating the I-beam welding plate 8, a plate groove structure is formed on the back of the embedded welding plate 2, and the structural steel bar 6 can be hung on the plate groove structure, and a welding plate groove is also formed in the described embedded welding plate 2, and safety bolt chute 5 and safety bolt steel bar 3 for detecting the degree of downward inclination of the cantilevered I-beam 4 are provided on both sides of the welding plate groove; Rib 3, the embedded welding plate 2 installed in the reinforced concrete structure 1 can be taken out as a whole, which is convenient for removing the cantilevered I-beam 4 and reusing the embedded welding plate 2, and the groove formed when the embedded welding plate 2 is removed can be smoothed when the external wall is plastered later.
进一步地，本发明所述的一种承插式悬挑脚手架的安装方法，其中通过所述斜拉组件将高强螺栓14和悬挑工字钢4相连接，通过相应拉杆螺帽18与拉杆钢筋19的配合；可调节相应上拉螺杆17或下拉螺杆13的整体长度，以便达到调节悬挑工字钢4的水平状态。Further, in the installation method of a socket-type cantilevered scaffolding according to the present invention, the high-strength bolt 14 is connected to the cantilevered I-beam 4 through the cable-stayed assembly, and the corresponding pull-rod nut 18 cooperates with the tie-rod steel bar 19; the overall length of the corresponding pull-up screw 17 or pull-down screw 13 can be adjusted so as to adjust the horizontal state of the cantilevered I-beam 4.
在实际施工过程中，要求所述保险栓钢筋3必须将工字钢焊板8固定在工字钢焊板槽7内，防止悬挑工字钢4受外力过大时，产生向下弯折现象，若保险栓钢筋3被拉出于保险栓滑槽5，则该悬挑工字钢4应立即拆除，不能继续悬挑作业，以便提高其施工作业的安全性。另外，如果设置于上部的高强螺栓14不满足拉力要求，也可考虑在下部采取部分支撑卸荷方式，采取下部支撑点方式，即在下层相应位置处也设置高强螺栓14，通过采取对称布置上拉组件的方式，来提高整个装置的安全稳定性。In the actual construction process, it is required that the safety bolt reinforcing bar 3 must fix the I-beam welding plate 8 in the I-beam welding plate groove 7, so as to prevent the overhanging I-beam 4 from being bent downward when the external force is too large. In addition, if the high-strength bolts 14 installed at the upper part do not meet the tensile requirements, it is also possible to consider adopting a partial support and unloading method at the lower part, and adopt a lower support point method, that is, high-strength bolts 14 are also installed at corresponding positions on the lower layer, and the safety and stability of the entire device can be improved by adopting a symmetrical arrangement of the pull-up components.
采用本发明所述技术方案，解决了现象普通悬挑工字钢不可避免的缺陷，普通型钢悬挑架需要在建筑物结构上穿孔，这会对建筑物造成局部结构的损伤；并且施工费时、费力；同时还需要增加50～60％的工字钢材料来用于固定脚手架，浪费建材。而同现有的花篮拉杆式工具悬挑架相比，也减少了用于穿墙使用的高强螺栓的使用量，并且能提高其安装效率，降低了悬挑型钢的拆除过程的安全问题。Adopting the technical scheme of the present invention solves the unavoidable defect of ordinary cantilevered I-beams. The ordinary cantilevered steel cantilever needs to be perforated on the building structure, which will cause local structural damage to the building; and the construction is time-consuming and laborious; at the same time, it is necessary to increase 50-60% of I-beam materials to be used for fixing the scaffolding, which wastes building materials. Compared with the existing turnbuckle rod type tool cantilever, it also reduces the amount of high-strength bolts used for penetrating walls, improves its installation efficiency, and reduces the safety problems in the process of dismantling the cantilevered steel.
综上所述，采用本发明所述技术方案，其适应范围广，具有结构简单、制作、安装和使用方便，并便于施工，不仅降低了施工作业成本，在拆除重复使用方面效果明显，还可节省资源和费用，能够重复使用，对后期砌体及外墙施工等无影响，同时，还能达到方便有效地完成脚手架的悬挑，节约施工成本，具有使用便捷，后期拆除无隐患，安全可靠，工作效率高等优点，适合推广应用。In summary, the technical solution of the present invention has a wide range of applications, simple structure, convenient manufacture, installation and use, and is convenient for construction. It not only reduces construction operation costs, but also has obvious effects in dismantling and reusing, and can also save resources and costs.
