Problems solved by technology
[0002] The existing industrial and civil door frames are fixed to the wall, mainly using the fixed mounting parts on the door frame and the metal prefabricated body of the wall to be connected by welding. The mounting parts on the door frame must be reserved in advance according to the site opening wall The location of a good embedded part depends on the site. It needs electric welding to implement it. During the installation process, the adjustment range of the matching gap between the door frame and the wall is small and difficult, and the installation accuracy and efficiency are low.

Embodiment Construction
[0020] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.
[0021] Such as figure 1 with figure 2 As shown, a non-welded door frame installation structure, including a door frame 1, a number of mounting holes 3 are symmetrically opened on the door frame 1, and a number of limit claws 4 protrude from the mounting holes 3 along the periphery of the hole to the inside of the door frame 1, The limit claw 4 and the door frame 1 are integrally formed by stamping.
[0022] Hollow top wall screws 5 are pre-installed in the installation holes 3, such as image 3 with Figure 4 As shown, the hollow top wall screw 5 is a cylinder 51 structure with a stepped hole 53. On the outer wall of one end of the cylinder 51, a convex ring 52 protrudes radially outward. The outer diameter of the cylinder 51 is Smaller than the aperture of the mounting hole 3, the outer diameter of the protruding ring 52 is greater than the a...

The invention relates to a non-welding type door frame installing structure, and belongs to the field of door frame installation. The non-welding type door frame installing structure comprises a door frame. A plurality of installing holes are symmetrically formed in the door frame and protrude and extend from the peripheries of the holes to the interior of the door frame to form a plurality of limiting clamping claws. Hollow wall ejecting screws are preinstalled in the installing holes. The door frame is placed in a door hole of a wall. Installing screws penetrate through the hollow wall ejecting screws and extend into the wall so that one ends of the hollow wall ejecting screws can be connected with the door hole in a butt joint mode. The door frame is fixed into the door hole of the wall by screwing down the installation screws. The door frame and the wall can be positioned by adjusting the hollow wall ejecting screws according to the door hole gap of the wall on site, the errors caused by measurement errors of the door hole size on site to installation position gaps are eliminated, and installation accuracy is ensured; meanwhile, in the installation process of the door frame and the wall, the door frame and the wall do not need to be fixed through welding, and the non-welding type door frame installing structure is flexible, changeable and high in applicability.
