Abstract
The utility model provides a seismic restraint steel door frame with simple structure, which can effectively reduce impact deformation of a door frame caused by the deformation of a wall body during an earthquake and impact to the door, ensure that the door can be opened normally even in the state of deformation caused by the earthquake to enable people to escape, and increase the escape probability of people during the earthquake. The seismic restraint steel door frame comprises an upper frame, a lock side mullion, a doorsill and a hinge side mullion, wherein two ends of the upper frame and two ends of the doorsill are respectively connected via the lock side mullion and the hinge side mullion. The seismic restraint steel door frame is characterized in that both the upper frame and the lock side mullion comprise inner frames and outer frames that are fastened and are mutually matched via elastic coupling pieces.
Description
Technical field
The utility model relates to the shake-proof technology field, is specially the shatter-proof doorframe of a kind of steel.
Background technology
Common steel door frame all adopts integral structure, when doorframe is installed, two kinds of mounting meanss are arranged usually, a kind of be reinforcing bar freeze grouting the mode that installs and fixes (freeze on steel framework with reinforcing bar one end, the other end freezes on the building steel embedded part or on the iron that is fixed on body of wall expands, then in the pour water mode that installs and fixes of silt particle slurry of doorframe inner chamber), another kind is directly directly doorframe and body of wall to be installed and fixed with the iron expansion bolt, these two kinds of mounting means doorframes and building all are that rigidity is connected and fixed form, under normal circumstances, mounted doorframe and door all leave the gap of 2mm～6mm between the sheet, guarantee that a sheet can normally open.When earthquake takes place when, the building wall body deformability can directly act on doorframe by the rigidity connector of installing to be caused doorframe to be squeezed impacting and inclination and distortion and the door sheet is stuck, it can't normally be opened, simultaneously, the flexural deformation that is hit of lock side munnion also can be blocked dead bolt a sheet can't be opened, personnel can't the very first time by a door escape hedging.
Summary of the invention
At the problems referred to above, the utility model provides a kind of steel shatter-proof doorframe, it is simple in structure, the blastic deformation that owing to deformation of wall doorframe is produced in the time of effectively alleviating earthquake, reduce the impact of opposite house, guarantee that door can normally open under the earthquake shock deformation state being subjected to, allow people's escape of being opened the door, the escape probability of the personnel during the raising earthquake disaster.
Its technical scheme is such, it comprises upper ledge, lock side munnion, mud sill and hinge side munnion, described upper ledge and mud sill two ends are welded to connect by lock side munnion and hinge side munnion respectively, it is characterized in that: described upper ledge and described lock side munnion include inside casing and housing, cooperate by Flexible Connector between the mutual spiral-lock of described inside casing and housing, described inside casing and housing.
It is further characterized in that: be connected by spring between the inside casing of described upper ledge and the housing; Described spring is fixed in the housing inboard of described upper ledge; Described spring is provided with three, and described three springs are evenly arranged along described upper ledge length direction; Be connected by M shape brace between the inside casing of described lock side munnion and the housing; Described M shape brace is fixed in the housing inboard of described lock side munnion by connector; Described M shape brace is provided with five, and described five M shape braces evenly distribute along described lock side munnion length direction; All be filled with glass wool in the inside casing of the inside casing of described upper ledge and the cavity between the housing and described lock side munnion and the cavity between the housing; The housing of described upper ledge and the two ends of described mud sill are welded to connect with the housing of described lock side munnion, described hinge side munnion respectively.
Compare with common steel sash structure, the beneficial effects of the utility model are: its upper ledge and lock side munnion are inside casing, the branch body structure of the mutual spiral-lock of housing, pass through spring between inside casing and the housing, Flexible Connectors such as M shape brace are connected, when deformation of wall, the housing compressive deformation, in, spring between the housing and M shape brace can play efficient buffer and negative function to distortion, the feasible upper ledge that directly cooperates with the door sheet, the inside casing of lock side munnion is indeformable within the specific limits or be out of shape less, guaranteed to have the gap of necessity between door sheet and the inside casing and be not stuck, a sheet can normally be opened under the deformation of wall state; Filling glass cotton between inside casing and the housing can further play buffering and offset the effect that housing is out of shape, and then guarantee can normally open at the situation Xiamen of deformation of wall sheet.
