The support frame also includes a first support component symmetrically arranged on both sides of the upper end of the door frame and a second support component symmetrically arranged on both sides of the lower end of the door frame.
[0006] The first support component includes right-angled arc-shaped clamping plates symmetrically installed in the annular grooves on the front and rear sides of the door frame. Support inclined rods are installed on the right-angled arc-shaped clamping plates. A connecting inclined plate is connected between the two ends of the right-angled arc-shaped clamping plate. A first tension rod is installed between the two connecting inclined plates on the front and rear sides of the door frame.
[0007] The second support component includes T-shaped clamping plates symmetrically installed in the annular grooves on the front and rear sides of the door frame. A second tension rod is installed between the two T-shaped clamping plates on the front and rear sides of the door frame. A horizontal connecting rod for binding with wall steel bars is fixed on the T-shaped clamping plate.
[0008] As a further improvement of the utility model, adjustment through holes are arranged along the length direction of the horizontal connecting rod. A limit screw is installed in the adjustment through hole. The limit screw is bound and connected with the wall steel bars to prevent the door frame from sliding left and right during pouring.
[0009] As a further improvement of the utility model, a connecting rod is installed between the two support inclined rods on the same side of the door frame.
[0010] As a further improvement of the utility model, the two ends of the connecting rod are connected to the two support inclined rods through fasteners. The connection through fasteners is convenient for disassembly.
[0011] As a further improvement of the present utility model, a third pair of tie rods is installed between the two connecting rods.
[0012] As a further improvement of the present utility model, the right-angled arc-shaped clamping plate is hinged to the support inclined rod, and the support inclined rod is a telescopic rod, which is convenient for adjusting the support angle of the support inclined rod.
[0013] The beneficial effects of the present utility model are as follows: The present utility model can ensure that after the door frame of the civil air defense door is erected and the concrete is poured, the verticality of the front surface and the inner side of the left and right frames of the door frame meets the requirements, ensuring the stability and reliability of the door frame support frame; after the door leaf is installed and adjusted, the fitting gap is within the industry requirements, meeting the protection and airtight performance requirements of the civil air defense door.
