Before installation and construction, reasonable arrangement is carried out in advance, specifically, construction drawings are designed according to the on-site cantilever structure 3, a construction area is confirmed (so as to avoid influencing other construction areas), selection of building materials is determined (for example, the sizes and materials of the main beam 12, the secondary beam, the suspender 21 and the like are determined), stress measurement and calculation are carried out on the whole construction platform to form a calculation book, corresponding experts are organized to demonstrate stress of the suspension platform, and the demonstration can be implemented through the method so as to ensure the stability of the construction platform for installing the cantilever structure 3 curtain wall and the construction safety of construction workers. During installation construction, the suspension platform 1 is assembled on the ground in step S100, so that the assembly difficulty and cost of the suspension platform 1 are reduced, and the construction safety of construction workers is ensured. Thereafter, in step S200, the suspended platform 1 is hoisted to the lower side of the cantilever structure 3 by the crane prepared in advance, so that the suspended platform 1 is hoisted, and the stability of the suspended platform 1 is ensured. Then, a scaffold structure is installed at the extension 11 of the suspended platform 1 for a construction worker to stand on the scaffold structure to install a curtain wall for the sidewall of the cantilever structure 3, through step S300. Like this, accomplish the installation that is used for the construction platform of encorbelmenting structure 3 curtain installation with the mounting method through the construction platform that is used for the installation of encorbelment structure 3 curtain, make the installation that is used for the construction platform of encorbelmenting structure 3 curtain installation go on in order and rationally, reduced the installation degree of difficulty and the cost of the construction platform that is used for the installation of the structure 3 curtain of encorbelmenting, the convenience of the construction platform installation that is used for the installation of the structure 3 curtain of encorbelmenting has been promoted, the construction cycle of the construction platform installation that is used for the installation of the structure 3 curtain of encorbelmenting has been shortened, the stability of the construction platform that is used for the installation of the structure 3 curtain of encorbelmenting has been guaranteed, be convenient for realizing the standardized construction of curtain.
In some embodiments, the mounting of the scaffolding structure on the extension 11 of the suspended platform 1 includes erection of a scaffolding body, connection of the scaffolding body to the suspended structure 3 by wall connectors, full hanging of a safety net outside the scaffolding body, and the like.
Optionally, as shown in fig. 1-4 in combination, assembling the suspended platform 1 on the ground comprises the following steps:
step S110, connecting a main beam 12 and a secondary beam of the suspension platform 1;
and S120, laying templates on the main beams 12 and the secondary beams.
In this way, through step S110 and step S120, the connection (for example, welding connection) of the main beam 12 and the secondary beam and the laying of the template on the main beam 12 and the secondary beam are completed on the ground, so that the construction of the suspension platform 1 is completed, a stable suspension platform 1 is formed, and the stability of the suspension platform 1 and the safety of construction when the suspension platform 1 is hoisted in the subsequent step are improved.
Optionally, as shown in fig. 1-3 and 5, hoisting the suspended platform 1 to the lower part of the cantilever structure 3 includes the following steps:
step S210, hoisting the suspension platform 1 to the position below the cantilever structure 3;
and S220, connecting the suspension platform 1 with the cantilever structure 3 through the connecting structure 2.
In this way, through steps S210 and S220, the suspension platform 1 is lifted to the lower side of the cantilever structure 3 by the crane, and the construction worker completes the connection of the suspension platform 1 and the cantilever structure 3 by using the connection structure 2, thereby completing the lifting of the suspension platform 1 below the cantilever structure 3. The suspension platform 1 and the cantilever structure 3 are connected through a suspension rod 21, a diagonal draw bar 22, a connecting cable 23 and the like, so that the stability of connection between the suspension platform 1 and the cantilever structure 3 is ensured.
Optionally, as shown in fig. 1-3 and 6, hoisting the suspended platform 1 to the lower part of the cantilever structure 3 includes:
step S230, sequentially hoisting a plurality of suspension platforms 1 along the length direction of the cantilever structure 3 below the cantilever structure 3;
and step S240, connecting the adjacent suspended platforms 1.
In this way, through the steps S230 and S240, the plurality of suspended platforms 1 are sequentially hoisted to the lower side of the cantilever structure 3 along the length direction of the cantilever structure 3, and the adjacent suspended platforms 1 are connected, thereby completing the hoisting of the integral suspended platform 1. Wherein, through adopting a plurality of platforms 1 of suspending in midair to hoist in proper order, reduced the degree of difficulty and the risk of suspending in midair of platform 1, the security when having promoted the construction platform installation that is used for the installation of the 3 curtain of structure of encorbelmenting. Moreover, the installation of the construction platform for installing the cantilever structure 3 curtain wall can be orderly and reasonably carried out, the installation difficulty and the cost of the construction platform for installing the cantilever structure 3 curtain wall are reduced, the convenience for installing the construction platform for installing the cantilever structure 3 curtain wall is improved, the construction period for installing the construction platform for installing the cantilever structure 3 curtain wall is shortened, the stability of the construction platform for installing the cantilever structure 3 curtain wall is ensured, and the standardized construction of the curtain wall is convenient to realize.
Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
