[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] According to Figures 1-4 As shown in the figure, it includes a portal rigid frame body 1. Four groups of threaded holes 11 are opened on both sides of the portal rigid frame body 1, and eight groups of mounting holes 12 are opened at the top of the portal rigid frame body 1. Anti-deformation mechanisms 2 are installed at both ends of both sides of the portal rigid frame body 1. The anti-deformation mechanism 2 includes fixing plates 21. The number of fixing plates 21 is four groups, and the four groups of fixing plates 21 are respectively placed at the positions of the two top corners on both sides of the portal rigid frame body 1. Both ends of the fixing plate 21 are screwed and installed with the corresponding threaded holes 11 through fixing bolts 22. Installation rods 23 are installed at the top of the fixing plate 21. Installation rings 24 are sleeved on the outer surfaces of the installation rods 23. One end of the connecting rod 25 is installed on the side surface of the installation ring 24. The two connecting rods 25 are both arranged directly above the portal rigid frame body 1. Installation sleeves 26 are installed at the middle positions of the outer surfaces of the connecting rods 25. Connecting columns 27 are installed at the bottom positions of the outer surfaces of the installation sleeves 26. Installation discs 28 are installed at the bottom ends of the connecting columns 27. Four groups of installation bolts 29 are movably screwed inside the installation discs 28. The four groups of installation bolts 29 are centrosymmetrically arranged with the center point of the installation disc 28. The outer diameter of the bottom end of the installation bolt 29 is adapted to the inner diameter of the installation hole 12. The bottom ends of the installation bolts 29 respectively extend into the corresponding installation holes 12 and are movably screwed with them.

[0021] One end of a support plate 3 is installed on the inner sides of the two fixing plates 21. A number of support rods 31 are arranged in an array at the top of the support plate 3. The top ends of the number of support rods 31 are installed on the inner wall of the top of the portal rigid frame body 1. A number of limiting rods 32 are arranged in an array on one side of the support plate 3. One end of the number of limiting rods 32 is installed on the inner wall of one side of the portal rigid frame body 1.

[0022] During use, the four groups of fixing plates 21 will be respectively installed at the positions of the two top corners on both sides of the portal rigid frame body 1. For reference, see Figure 1As shown, the arrangement of the four groups of fixing plates 21 can limit the positions at the two top corners on both sides of the gabled frame body 1, thereby preventing the gabled frame body 1 from deforming during use. The corresponding two groups of fixing plates 21 are connected through the corresponding two groups of mounting rods 23, the corresponding two groups of mounting rings 24 and the corresponding connecting rods 25, so that the corresponding two groups of fixing plates 21 can restrict and limit each other. The corresponding connecting rod 25 can be installed on the top of the gabled frame body 1 through the corresponding mounting sleeve 26, the corresponding connecting column 27, the corresponding mounting disc 28 and the corresponding plurality of mounting bolts 29, so that the connecting rod 25 can be fixed directly above the gabled frame body 1. The arrangement of the plurality of support rods 31 and the plurality of limiting rods 32 can support the positions at the two top corners on both sides of the gabled frame body 1 accordingly, thus further playing a role in limiting and supporting the gabled frame body 1, and further preventing the gabled frame body 1 from deforming during use. Through the arrangement of the above components, the problem that due to the characteristics of the shape of the gabled frame body 1 itself, during the construction of the gabled frame body 1, the top of the gabled frame body 1 is prone to deformation at the two corners on both sides, resulting in insufficient support force of the gabled frame body 1 for the four side walls and the roof of the factory building, and further causing the collapse of the factory building can be effectively solved.
