The position, number, and installation method of the lifting rings 161 should meet the design requirements. During construction, the construction personnel should frequently check the lifting rings 161. If the nuts are loose or damaged due to collision of the lifting rings 161, the construction personnel should immediately tighten or replace the lifting rings 161.

[0045] When the steel formwork structure 10 with the opening is used, the steel formwork structure 10 with the inclined support should be stacked face to face and rely on the wall. At this time, an included angle is formed between the steel formwork and the ground. The included angle is a self-stabilizing angle, and the self-stabilizing angle can be 75°-80°. If the steel formwork structure 10 without the inclined support is placed, the construction personnel need to erect a scaffold on the site. If the steel formwork structure 10 is not on the wall, the steel formwork structure 10 should be directly placed in a larger scaffold. It is not allowed to rely on other formworks or components to avoid sliding and falling. In the use process of the steel formwork structure 10, the anchor bolt of the steel formwork structure 10 with the inclined support is most easily damaged. Therefore, when the steel formwork structure 10 with the inclined support is installed, the construction personnel need to add double-sided protective plates to the steel formwork structure 10 with the inclined support, and extend the weld of the steel formwork structure 10 with the inclined support, so as to protect the anchor bolt of the steel formwork structure 10 with the inclined support. When the steel formwork structure 10 lands, the steel formwork structure 10 should be avoided from colliding with the anchor bolt as much as possible.

[0046] The steel formwork structure 10 can be hung on the outer wall of the triangular frame, and the material of the outer hanging tripod hook should meet the national standard and be attached with the material certificate. Moreover, the construction personnel should frequently check the hook. When the steel formwork structure 10 is lifted, whether the steel formwork structure 10 is in a stable state should be paid attention to. When the steel formwork structure 10 is in place, the steel formwork structure 10 should avoid colliding with the outer hanging tripod. When the steel formwork structure 10 is lifted, the steel formwork structure 10 should pay attention to not scratch the safety net. When the construction personnel construct, only the operating tools are allowed to be placed on the outer hanging tripod, and the construction materials are not allowed to be stacked. When the outer wall form is removed, a plurality of operators should be avoided from being concentrated in one place. In any case, the stacking load of the outer hanging tripod should be less than 120kg / m. When the outer hanging tripod is installed, the concrete strength of the wall body should be greater than 7.5MPa.

[0047] The installation process of the utility model is as follows: before the steel formwork structure 10 is installed, the transportation personnel transport the steel formwork structure 10 to the construction site. Then, the construction personnel check the specification size and flatness of the steel formwork structure 10 one by one, and the construction personnel also need to accept the combined plate surface seam width, height difference and female-male angle form. The construction personnel can assemble the steel formwork structure 10 according to the form drawing after the steel formwork structure 10 is accepted.

[0048] When the steel formwork structure 10 is installed, the construction personnel sets the vertical ribs 112 in the vertical direction and connects the vertical ribs 112 with the steel formwork 111. The steel formwork 111 is provided with an opening 1111. Then, the construction personnel passes the connecting bolts 171 through the vertical ribs 112, so that the connecting bolts 171 are connected with the second connecting portions 1722 of the connecting clamps 172. The construction personnel sets the horizontal back ribs 113 in the horizontal direction. The construction personnel positions the wing plates 173 through the positioning grooves 1732 and the positioning blocks 1132. Then, the construction personnel connects the fastening bolts 17 with the first connecting portions 1721 through the through holes 1731. Further, the horizontal back ribs 113 are connected with the vertical ribs 112 through the connecting clamps 172. Subsequently, the construction personnel sets the upper beam side form 12 at the upper end of the opening 1111 and connects the upper beam side form 12 with the steel formwork 111. The construction personnel sets the lower beam side form 13 at the lower end of the opening 1111 and connects the lower beam side form 13 with the steel formwork 111. Then, the construction personnel connects the top blocking plate 14 with the upper beam side form 12 through bolts. The construction personnel connects the beam cover plate 15 with the lower beam side form 13 through bolts. The construction personnel connects the side blocking plate 16 with the vertical ribs 112 through bolts. Subsequently, the construction personnel connects the vertical ribs 112 of two adjacent formwork bases 11 through the splicing bolts 192, so that the two adjacent formwork bases 11 are connected.

[0049] At the inside corner position, the construction personnel connects one side of the inside corner splicing angle steel 18 with the inside corner and passes the hook head bolts 183 through the thick steel plate 182 and the angle form horizontal partition plate 1811. The angle form horizontal partition plate 1811 is connected with two angle form vertical ribs 1812, which are connected with two adjacent vertical ribs 112 respectively, so that the two adjacent vertical ribs 112 are connected at the inside corner position. At the outside corner position, the construction personnel connects one side of the outside corner splicing angle steel 19 with the outside corner and connects the other side of the outside corner splicing angle steel 19 with the vertical ribs 112 through the splicing portions 191. Therefore, the two splicing portions 191 are connected with two adjacent vertical ribs 112 through the splicing bolts 192 respectively, so that the two adjacent vertical ribs 112 are connected at the outside corner position. After the steel formwork structure 10 is installed, the construction personnel can reinforce and correct the steel formwork structure 10 and should check the perpendicularity, the joints and the firmness of the steel formwork structure 10 one by one.

[0050] The utility model provides a kind of steel formwork structure with opening, which is provided with an opening on the steel formwork.Compared with the construction technology of the whole steel large formwork, the steel formwork structure with opening can reduce the material input of the large formwork, effectively saving the cost.In the traditional whole steel large formwork, the door and window opening is reserved by using a plug frame, and the opening is a fully closed structure.When working, the construction personnel must climb over the top of the wall formwork from one side of the wall to the other side, which is very inconvenient and has low work efficiency.In the steel formwork structure with opening of the utility model, an opening is provided on the steel formwork, and the construction personnel can freely walk back and forth between the two working surfaces through the opening.During the construction process, the construction personnel can operate and inspect the two working surfaces of the steel formwork structure at the same time.Therefore, the construction personnel can conveniently construct on the steel formwork structure of the utility model, effectively solving the technical problem of the inconvenience of the construction of the existing large formwork structure.Compared with the traditional whole steel large formwork, the steel formwork structure of the utility model is beneficial to improving the work efficiency of the construction personnel.

[0051] The steel formwork structure with opening adopts a pre-assembled assembly method, which can reduce a large amount of on-site construction work compared to the traditional wood formwork technology, effectively saving the workload of the construction personnel.During the construction of the traditional wood form, the phenomena of swelling, eating and running of the formwork may occur, and the quality of the R and L corners cannot be guaranteed.Especially at the door and window opening, if the span size is large and the height is high, it is easy to cause deformation of the opening, which causes great difficulty in decoration, resulting in the inability to install the door and window or the small size of the door and window.The steel formwork structure with opening not only inherits the advantages of the whole steel large formwork, such as high strength and good integrity, but also greatly improves the forming process of the door and window opening.The door and window opening is sealed by a steel blocking plate, and is open, with good overall rigidity.The deformation of the opening can be observed at any time during concrete pouring, and the common problems of the traditional wood formwork will not occur.Furthermore, the quality of the R and L corners and the size of the wall section can be fully guaranteed, which can better meet the conditions of later decoration and construction.

[0052] In summary, although the utility model has been disclosed as above with preferred embodiments, the above preferred embodiments are not intended to limit the utility model, and those skilled in the art can make various modifications and decorations without departing from the spirit and scope of the utility model, therefore the protection scope of the utility model is subject to the scope defined by the claims.
