Referring to fig. 7, a plurality of grid square tubes 1 are parallelly installed on keel angle steel 3, and the specific number is determined according to the length of the keel angle steel 3 and the distance between the grid square tubes 1, so that a grid ceiling is formed.
In the construction, in order to avoid the waste that produces in the construction from dropping, the bottom of cantilever frame generally needs to be sealed, and in this embodiment, in order to seal the cantilever frame, closed form 4 has been set up on I-steel 1000. The closed template 4 is a general closed template, and comprises a template body with a sealing effect, and a batten back edge and a steel pipe main edge which are arranged on the lower surface of the template body and used for supporting the template body. In this embodiment, in order to make things convenient for later stage rubbish clearance to improve the turnover rate of closing 4 templates, add one deck galvanized iron on the upper surface of closing 4 template bodies of template, galvanized iron surface is more smooth than general wooden template body, has higher intensity moreover, and difficult rust corrosion can promote the efficiency of rubbish clearance, reduces 4 in use of closing template and is corroded or the possibility of damaging moreover. In order to avoid the fine waste and water generated in the construction from sliding downwards along the wall body, the closed formwork 4 in the embodiment is arranged close to the wall body of the shear wall, and the lap joint of the galvanized iron sheet and the joint of the closed formwork 4 and the wall body are sealed by weather-resistant glue.
For the installation of convenient closed form 4, can set up the draw-in groove of placing of laying closed form 4 on the cantilever frame, for the landing in convenient upper strata construction rubbish floor, improve the efficiency of rubbish clearance simultaneously, place the draw-in groove and make closed form 4 to wall body one side slope, make closed form 4 and horizontal plane form an contained angle c, contained angle c satisfies 15 degrees and is less than or equal to 30, contained angle c is 15 in this embodiment.
In addition, because a large amount of waste water can be generated in the upper layer construction process, if the generated waste water flows downwards along the wall body, the appearance can be influenced, and part of decorated outer vertical surfaces can be polluted, so that a water retaining mechanism of the outer vertical surfaces needs to be arranged, and the waste water on the upper layer is prevented from flowing downwards. The overhanging frame in this embodiment is arranged on the shear wall, and the wall body is not provided with an opening for waste water to be collected inside, so that the water interception mechanism directly intercepts and discharges water, and the adopted water interception mechanism is an overhanging type water stop plate 5. In order to facilitate installation and removal, the overhanging type water stop plate 5 is arranged on the wall surface between the I-shaped steel 1000 and the closed template 4, the water stop device is made of metal materials, generally sheet metal materials such as iron sheets and the like which are common in construction places can be adopted, the overhanging type water stop plate 5 is in an L shape, the short side of the L shape is fixed on an outer wall body by an explosive bolt, and meanwhile, a rubber gasket 51 is arranged between the overhanging type water stop plate 5 and the wall body, so that flowing water on the wall body can flow onto the overhanging type water stop plate 5. In order to attach the overhanging type water stop plate 5 to the wall body, a top pressing angle steel 52 is further arranged on the outer side of the short side, during installation, a right-angle opening of the top pressing angle steel 52 faces upwards, one side of the top pressing angle steel 52 and the short side of the overhanging type water stop plate 5 are fixed on the wall surface together, and the short side of the overhanging type water stop plate 5 and a rubber gasket 51 on the inner side of the short side are tightly attached to the wall surface.
Because the overhanging type water stop plate 5 is arranged on the wall surface between the I-beam 1000 and the closed template 4, the I-beam 1000 is positioned below the overhanging type water stop plate 5, and the hole for installing the I-beam 1000 is formed in the wall body, so that the lower outer wall is polluted by the wastewater generated in the construction process of the floor where the I-beam 1000 is positioned, the hollow rubber rod for placing the wastewater to flow out is arranged at the bottom of the I-beam 1000, the hollow rubber rod is arranged at the part of the I-beam 1000 positioned in the wall body, the distance between the hollow rubber rod and the outer wall surface is generally adjusted between 290mm and 310mm according to the thickness of the wall body, and the distance between the hollow rubber rod and the outer wall surface in the embodiment is 300 mm.
Because grid square tube 1 is fixed on I-steel 1000 with the mode of approximate hanging in midair through fossil fragments angle steel 3 and connection snap ring 2, if the distance is too big between the fossil fragments angle steel 2 on same horizontal plane or the facade, grid square tube 1 fixed effect is not good, it is flagging easily, influence the impression, it can drop more probably, become the potential safety hazard, therefore, the distance between the fossil fragments angle steel 3 on the same plane should be less than 1000mm, in this embodiment, because the width of cantilever frame is not big, fossil fragments angle steel 3 on the horizontal direction is equipped with two, the distance between two fossil fragments angle steel 3 is 1000 mm.
In order to further improve the appearance of the bottom of the cantilever frame, in this embodiment, the lower surfaces of the i-steel 1000 and the closed template 4 and the supporting mechanism arranged on the lower surfaces adopt paint of the same color for color spraying treatment, and black paint spraying is adopted in this embodiment.
