Abstract
The invention relates to a combined type door frame of a fireproof door, and belongs to the technical field of fireproof doors. The combined type door frame of the fireproof door is used for being connected with a door leaf and comprises a frame first end, a frame second end and a frame connecting piece; the frame connecting piece is connected with the frame first end and the frame second end through expansion bolts to form an angle form structure. According to the combined type door frame of the fireproof door, the structure is simple, the installation is convenient, gaps between the door leaf and the door frame can be reduced, fire resistance performance of the door frame is improved, and the door frame is prevented from deformation.
Description
Technical field
The present invention relates to labeled door technical field, particularly relate to a kind of assembly type fireproof door frame.
Background technology
Whether labeled door effectively prevents fires, its fire-proof door leaf and fireproof door frame all no less importants.Existing fireproof door frame adopts too much wood materials, have ignored fire-protection rating requirement after reaching aesthetic; And some have ignored the fire proof seal at the contact surface place of door leaf and framework, destroy overall labeled door fireproof performance.In addition, also need to consider how to install firm, close the problems such as tight.
Summary of the invention
For solving the problem, the invention provides one and having compared with high fireproof and assembly type fireproof door frame close-connected with door leaf.
The invention provides a kind of assembly type fireproof door frame, for being connected with door leaf, comprising frame first end, frame the second end, frame connecting pieces; Described frame first end and described frame the second end are connected and composed corner-shape structure by expansion bolt by described frame connecting pieces.
This assembly type fireproof door frame, structure is simple, is convenient to install, and expansion bolt can be utilized to be connected with door leaf by the corner-shape structure of doorframe.Relative to integrated sash structure, assembly type doorframe, for door leaf structure more compact siro spinning technology, reduces doorframe and door wing gap, improves doorframe fire line, intercepts fire and smoke spread.
Preferred as the present invention, described frame first end and described frame the second end are equipped with heat-insulating fire-proofing plate.
Preferred as the present invention, described frame first end is identical structure with described frame the second end.
Preferred as the present invention, described frame first end or described frame the second end are ladder-shaper structure; Described frame connecting pieces is the right-angle structure with the inclined-plane that two are connected with described frame first end trapezoidal faces and described frame the second end trapezoidal faces respectively.
Preferred as the present invention, described frame first end or described frame the second end are cube like structure; Described frame connecting pieces is the right-angle structure with the plane that two are connected with described frame first end rectangular surfaces and described frame the second end rectangular surfaces respectively.
Preferred as the present invention, described corner-shape structure and door leaf junction are provided with the seal groove being with pre-buried fireproofing glue strip.
Preferred as the present invention, described door frame surface is provided with fire resistant coating.
Preferred as the present invention, be provided with support ironware in described frame first end, described frame the second end.
The present invention has following beneficial effect:
Combination fire-proof door sash structure of the present invention is simple, be convenient to install, and be conducive to reducing door leaf and doorframe gap, raising doorframe fire resistance, prevents door frame distortions.

Detailed description of the invention
Assembly type fireproof door frame of the present invention, comprises frame first end 1, frame the second end 2, frame connecting pieces 3.Described frame connecting pieces 3 respectively by expansion fastener, as expansion bolt connect described frame first end 1 and as described in frame the second end 2, described frame first end 1, described frame the second end 2, described frame connecting pieces 3 three form corner-shape structure.Consistent in order to make to connect compactness between doorframe with door leaf, described frame first end 1, described frame the second end 2 are designed to identical structure, finally make described corner-shape structure be a symmetrical structure.
As Fig. 1, the present invention designs described frame first end 1 or described frame the second end 2 is cube structure.Described frame connecting pieces 3 is the corner-shape structure less than the corner-shape structure of described frame first end 1, described frame the second end 2, described frame connecting pieces 3 three formation.This little corner-shape structure is the right-angle structure with the plane that two are connected with described frame first end 1 rectangular surfaces and described frame the second end rectangular surfaces respectively.When above-mentioned rectangular surfaces is connected by expansion bolt with plane, bolt connects in vertical plane direction, after fire causes temperature to raise, bolt expands and makes frame connecting pieces 3 and frame first end 1 and frame the second end 2 compact siro spinning technology, especially compact siro spinning technology between doorframe and door leaf, doorframe and door wing gap reduce.As preferably, as Fig. 2, the present invention also designs described frame first end 1 or described frame the second end 2 is ladder-shaper structure; Described frame connecting pieces 3 is for having the right-angle structure on the inclined-plane that two are connected with described frame first end 1 trapezoidal faces and described frame the second end 2 trapezoidal faces respectively.When above-mentioned trapezoidal faces is connected by expansion bolt with inclined-plane, bolt connects in straight bevel facet direction, after fire causes temperature to raise, bolt expands and makes trapezoidal faces and inclined-plane close contact, when doorframe is connected with door leaf, add ramp effect, make doorframe more be close to door leaf, further reduce gap between doorframe and door leaf, further increase doorframe fire resistance.
Also can improve doorframe fireproof performance in other respects.Such as, described frame first end 1, described frame the second end 2 are provided with heat-insulating fire-proofing plate 4.As Fig. 1, when frame connecting pieces 3 is enough thick, can also be provided with heat-insulating fire-proofing plate 4 in frame connecting pieces 3.When doorframe is connected with door leaf, forms fire proof heat-insulation layer at door leaf periphery, avoid door frame distortions, improve doorframe durability; The corner-shape structure that described frame first end 1, described frame the second end 2, described frame connecting pieces 3 three are formed and door leaf junction are provided with the seal groove being with pre-buried fireproofing glue strip, if this doorframe is for boats and ships, also again in this seal groove windproof adhesive tape can be set more; Described door frame surface is provided with fire resistant coating, as the fire proofing material mixed primarily of magnesia, magnesium chloride solution, remodeling agent etc., improves door frame surface fireproof performance.
In addition, in order to improve the fastness of doorframe, this frame connecting pieces 3 can be metalwork, also can be provided with support ironware in described frame first end 1, described frame the second end 2, utilizes metalwork to strengthen doorframe intensity, makes doorframe fire resistance period more permanent.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
