Environmentally friendly steel structure installation and construction method

Abstract

The present invention proposes an environmentally friendly steel structure installation and construction method, which includes the following steps: fixing the steel structure support ribs and the steel structure columns; setting the steel mesh; installing the aluminum formwork; pouring the mixed material through a mixing pouring head; and removing the aluminum formwork after the mixed material solidifies. In the actual implementation process, by pouring a mixture of mixed concrete and water-absorbing foamed particles, the connection nodes are covered in the mixture, thereby reinforcing the connection nodes and improving the seismic performance. At the same time, the steel mesh can effectively enhance the crack resistance of the wall. The water-absorbing foamed particles can absorb the moisture that penetrates into the mixture, accelerate the drying of the wall, avoid moisture corrosion of the connection nodes, and increase the service life of the steel structure. During the construction process, the aluminum formwork can be reused, reducing the generation of construction waste, thereby achieving the purpose of protecting the environment.

[0039] S5: After the mixed material solidifies, the aluminum template 4 is removed.

[0040] During the actual implementation process, the connection nodes are covered in a mixture of concrete and water-absorbing foam particles by pouring, thereby reinforcing the connection nodes and improving the seismic performance; the steel mesh can effectively enhance the wall's resistance to cracking; the water-absorbing foam particles can absorb the moisture in the concrete after pouring, accelerating the drying of the wall. At the same time, in daily use, the water-absorbing foam particles can absorb the moisture that penetrates into the wall, accelerate the drying of the wall, avoid moisture corrosion of the connection nodes, and increase the service life of the steel structure; during the construction process, the aluminum formwork can be reused to reduce the generation of construction waste, thereby achieving the purpose of protecting the environment.

[0041] Preferably, the steel structure support rib 2 used in step S1 is provided with a plurality of through holes for the mixed material to pass through. The mixed material entering the through holes strengthens the connection between the steel structure support rib 2 and the concrete after solidification.

[0042] Preferably, the aluminum template 4 used in step S2 has a casting hole at its upper end, a gate plate 41 for opening or closing the casting hole, a sliding groove connected to the gate plate 41 for sliding the gate plate 41, and a first drive device for sliding the gate plate 41. The gate plate 41 has corresponding holes corresponding to the casting holes.

[0043] Preferably, the first drive device includes a threaded seat mounted on the gate 41, an adjustment screw engaged with the threaded seat, and a drive motor for driving the adjustment screw. The threaded seat includes an adjustment nut engaged with the adjustment screw. The drive motor rotates the adjustment screw, which, through the engagement of the screw and the threaded seat, drives the gate 41 to slide open or close the casting hole.

In actual implementation, the leak-proof part closes the inner hole through the side wall of the elastic tube. When the casting tube is connected to the casting hole, the casting tube extends into the inner hole through the leak-proof hard tube to squeeze the side wall to open the inner hole, thereby opening the casting hole for casting. When the casting tube is removed, the side wall of the elastic tube recovers and closes the inner hole; the elastic tube is made of rubber material.

[0045] Preferably, the connection device used in step S2 includes a screw connecting the steel structure support rib 2 and the steel mesh 3, a first nut located on both sides of the steel structure support rib 2 to lock the steel structure support rib 2, and two second nuts located on the steel mesh 3 to lock the steel mesh 3.

During pouring through the mixing and pouring head 5, the mixing blade 51 thoroughly stirs the water-absorbing foamed particles with the concrete, evenly mixing the water-absorbing foamed particles into the concrete.

At the same time, prevent the water-absorbing foam particles in the mixing chamber from absorbing moisture from the concrete, causing the mixed materials to solidify quickly, and prevent the mixed materials from being unable to be discharged from the mixing chamber.
