Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense doors, and particularly relates to an angle steel member for a civil air defense door frame. Background Technique

[0002] The civil air defense door frame is mainly used for installing and supporting civil air defense doors to ensure that in emergency situations such as war and natural disasters, it can effectively isolate and resist external impacts and damages. The civil air defense door frame is usually made of high-strength steel, such as angle steel, channel steel, etc.;

[0003] The existing civil air defense door frame structures are mostly composed of single-layer angle steel or frame plates. For example, a civil air defense door frame of a Chinese utility model patent with the publication number CN215595323U. This application sets a support beam at the top of the frame body. The support beam can support the weight of the wall after the wall is built on the top of the door frame, thereby reducing the pressure borne by the frame body itself. Therefore, the possibility of the door frame deforming can be reduced. At the same time, multiple reinforcing plates are arranged on both sides of the frame body. The reinforcing plates can enhance the stability of the two side edges of the frame body. However, since the civil air defense door frame is directly poured into the concrete wall later, the flat setting on the outside of the frame body in this application, even with multiple anchor rods, cannot make the door frame and the concrete wall have a strong connection. That is, when a violent impact occurs from one side, it is easy for the frame body to be displaced and peeled off from the concrete wall. In addition, when the existing civil air defense door frame body is welded and assembled, external fixtures need to be used to fix each component to achieve the positioning connection between the components, resulting in low welding efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an angle steel member for a civil air defense door frame, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An angle steel member for a civil air defense door frame includes two door frame side plates, a threshold plate and a door head plate. The door frame side plates are fixedly connected to the threshold plate and the door head plate. A plurality of frame anchor hooks are fixedly installed on the rear sides of the door frame side plates, the threshold plate and the door head plate respectively. Two hinge bottom plates are fixedly installed on one side of one of the door frame side plates. Diagonal flat steels are fixedly installed at the joints of the two door frame side plates, the threshold plate and the door head plate respectively.

[0007] Preferably, two slots are respectively opened on the opposite sides of the two door frame side plates, and two slots are also respectively opened on the opposite sides of the threshold plate and the door head plate. Opening two slots on one side of the door frame side plates, the threshold plate and the door head plate respectively can facilitate the positioning connection of the door frame side plates and the threshold plate or the door frame side plates and the door head plate through diagonal flat steels.

[0008] Preferably, a triangular plate is fixedly connected between the two frame anchoring hooks, and both sides of the triangular plate are fixedly installed at the inner corners of the door frame side plate or the threshold plate and the inner side of the door head plate. Connecting the frame anchoring hooks through the triangular plate can improve the installation stability of the door frame side plate by pouring the frame anchoring hooks into the wall. At the same time, the bearing capacity of the door frame side plate can be improved through the triangular plate.

[0009] Preferably, an L-shaped insertion plate is fixedly installed on one side of the hinge bottom plate. Two connecting plates are fixedly installed on the side of the L-shaped insertion plate opposite to the hinge bottom plate. Four fixing seats are also fixedly installed on the hinge bottom plate on the side of the L-shaped insertion plate. A communicating screw groove is provided in the fixing seat and the hinge bottom plate. The hinge bottom plate is inserted and installed on one side of one of the door frame side plates through the L-shaped insertion plate and the connecting plate and welded and fixed. Installing the hinge bottom plate on one side of one of the door frame side plates through the L-shaped insertion plate and the connecting plate can pour concrete into the cavity between the hinge bottom plate and the L-shaped insertion plate and the connecting plate in the later stage, improving the tensile capacity of the hinge bottom plate and making the installation of the civil air defense door more stable.

[0010] Preferably, plugs are fixedly installed on both straight-edge parts on the outside of the inclined flat steel. The inclined flat steel is welded and fixed at the included angle between the door frame side plate and the threshold plate or between the door frame side plate and the door head plate. The plugs are inserted into the corresponding slots. Through the setting of the inclined flat steel and the plugs, the connection and positioning between the door frame side plate and the threshold plate or between the door frame side plate and the door head plate can be facilitated, making the welding structure between the door frame side plate, the threshold plate, and the door head plate more stable.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] For the civil air defense door frame angle steel part of the present utility model, the connection parts of the door frame side plate, the threshold plate, and the door head plate are connected through the inclined flat steel and the plugs, which can realize the quick positioning connection of the door frame side plate, the threshold plate, and the door head plate and facilitate the improvement of the welding efficiency;

[0013] The door frame side plate, the threshold plate, and the door head plate adopt an angle steel structure, and two frame anchoring hooks are installed at the inner corner positions of the door frame side plate, the threshold plate, and the door head plate through a triangular plate, so that one side of the door frame side plate, the threshold plate, and the door head plate can be in contact and fixed on the impact surface of the concrete wall, thereby improving the connection strength and bearing capacity between the overall door frame and the concrete wall. The hinge bottom plate is installed on one side of the door frame side plate through the L-shaped insertion plate and the connecting plate, which can improve the tensile capacity of the hinge bottom plate and ensure the stable installation and rotation of the civil air defense door.
