[0002] The prefabricated floor slabs used in existing buildings are cast in the workshop, with prefabricated steel skeletons in the walls, and then poured with cement, transported to the construction site, and assembled by workers and cranes. Prefabricated floor slabs are not absolutely easy to use. It is difficult to align the positioning holes of the wall during the assembly process, and there are problems with the sealing of the wall gaps. Therefore, it can be carried out through the prefabricated forming skeleton, which is a semi-prefabricated construction method. It can make the forming skeletons fully fixed and avoid the problem of poor sealing of the gaps between the walls. The existing M-shaped steel forming skeleton has been developed as the main structural support, and then the steel bars are tied and fixed to form a steel cage in the shape of the plate, which greatly reduces the assembly time of the forming skeleton and improves efficiency.

[0003] The molded frame is the main rigid support built into the wall. The prefabricated steel cage needs to be transported and assembled. Since the steel bars are fixed by bundling or welding, directly lifting the molded frame will cause uneven local force and deformation of the molded frame due to the unstable center position. Therefore, the utility model prepares a hoisting fixture for the molded frame, which is used to fix the molded frame to prevent the molded frame from being locally deformed during the lifting, transportation and installation process. Utility Model Content

[0017] Figure 2 : Schematic diagram of the steel frame structure installed in the utility model.

[0018] In the accompanying drawings, the list of components represented by each reference numeral is as follows: steel frame 8, square tube 1, cross beam 2, transverse through hole 11, first bolt 3, first support block 6, slot 12, second bolt 4, third bolt 5, second support block 7, flange 15, lifting ear 13, lifting hole 14. DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1-2 As shown: a formed steel frame lifting fixture, including square tubes 1 installed on both sides of the steel frame 8, the cross-section of the steel tubes is a square, the square tubes 1 are parallel to each other, the corresponding surfaces are close to the sides of the steel frame, and extend along the length direction of the steel frame 8, and multiple beams 2 are installed between the steel frames 8 on both sides; the four corresponding faces of the square tubes, one face overlaps and is close to the side of the steel frame, and the other adjacent face is in the same plane as the plane of the steel frame.

[0021] The square tube 1 is provided with a plurality of transverse through holes 11 along the length direction for the first bolt 3 to pass through, and the intersection of the crossbeam 2 and the square tube 1 is fixed by the first bolt 3; the transverse through holes are circular holes that pass through the opposite sides of the square tube and are used to install the first bolt to fix the square tube and the crossbeam.

[0022] The square tube 1 is also provided with a slot 12 along the length direction, and the slot 12 is provided in a direction perpendicular to and one-to-one correspondence with the direction of the transverse through hole 11, for inserting the first support block 6, which is inserted into the slot 12 and fixed by the second bolt 4. The first support block is a strip structure, and after being inserted into the slot, the corresponding steel frame portion has an extension, and the extension portion is used to support the steel frame.

[0023] The utility model lifts by fixing the square tube with a hoist. After the square tube and the cross beam are spliced ​​and fixed, as an integral frame, the cross beam has two, and the composed frame is a square structure. The intersection of the square tube and the cross beam is fixed by a first bolt, which then plays a role of resisting torsion after lifting.

[0024] The crossbeam is used to support the square tubes on both sides and to fix the steel frame by tying the steel bars to fix the entire steel frame to the frame. The first support block increases the supporting performance of the steel frame.

[0025] The square tubes and beams are installed by bolts and can be easily disassembled and reused after being spliced ​​with the steel frame.

[0026] The steel frame designed in the utility model mainly utilizes M-shaped steel, which has the advantage that the stamped rolled edges increase the rigidity and stability of the light steel lattice, and also increase the bond strength with concrete, making the combination of prefabrication and cast-in-place more reliable. At the same time, the steel bar connection structure is simple, and the overall seismic resistance, impermeability and fire resistance are more superior.

[0027] The steel skeleton is prefabricated in the factory, accurately hoisted and connected on site, and finally poured with concrete, eliminating the process of supporting and removing the formwork. It can also avoid the formation of weak links in the post-casting nodes and post-casting strips, reducing energy consumption and costs.

[0028] This type of steel is a special zinc-aluminum-magnesium steel product with high strength, high corrosion resistance and easy forming, which can be used for the structural walls of high-rise buildings. The seismic resistance, tensile strength and yield ratio of this type of steel have been proven to be able to replace high-strength steel bars.

[0029] like Figure 1 As shown: the square tube 1 is also provided with a longitudinal through-hole, which is perpendicular to the direction in which the transverse through-hole 11 is opened, and is used to pass the third bolt 5, and the third bolt 5 is used to fix the second support block 7 to the square tube 1. The transverse through-hole and the longitudinal through-hole are located on the corresponding end faces of the square tube, and are used to make the first support block and the second support block different in length direction after being fixed, so that the steel skeleton has support points in both the transverse and longitudinal directions. The specific second support block does not pass through the slot, but is abutted against and fixed to the square tube. There are two groups of specific corresponding square tubes, which are evenly arranged. The first support block 6 and the second support block 7 are both plate structures, having a plug-in part that cooperates with the slot 12 and a hook-shaped part for support. The plug-in part also has a socket for the bolt to pass through, which is convenient for the bolt to be positioned, fixed, and disassembled and installed. The first support block and the second support block have the same structure, can be disassembled and installed, and can be reused.

[0030] like Figure 1 As shown: the crossbeam 2 is composed of bar steels arranged symmetrically on both sides. The ends of the bar steels on both sides are fixed by connecting plates to form a crossbeam 2 with a square end face. The side of the bar steel is bent twice inwardly, and the bar steel is provided with a weight-reducing groove. The support strength is improved after the bar steels on both sides are bent. At the same time, a groove is reserved between the bar steels on both sides for the first bolt to pass through. The square tube 1 is formed by the mother tube and the child tube being fixed by docking. The mother tube and the child tube are connected at the docking point with a flange 15, which is opened and fixed by bolts. The mother tube is longer than the child tube, and is used to select child tubes of different lengths for assembly according to the length of the steel skeleton, so that the overall length of the square tube is just matched. It is fixed by a flange, and can be detached and matched for reuse. The end of the square tube 1 has a lifting ear 13, and the lifting ear 13 has a lifting hole 14. The end of the square tube has a sealing plate, which is fixed by welding. The sealing plate is used to weld and fix the lifting ear. The lifting holes of the square tubes on both sides correspond to each other, and are used for the lifting tool to pass through for lifting.

[0031] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
