Description

A kind of roof door

Technical field

This utility model relates to building engineering field, is specifically related to the roof staircase that door opening is located in sloped roof cover plate and joins The roof door that set uses.

Background technology

Ancient architecture is mostly brick and tile ramp-roof structure, and roof is seldom utilized.After man invented and application cement, build Building industry and obtained unprecedented development, roof also can build up firm flat-tope structure, fully can add roof from these people To utilize, particularly modern countryside.But, to conveniently utilize roof, it is necessary to by stair, but prior art is also the most well Roof in scheme.From setting up stair within doors, it is necessary to build a staircase higher than roof parapet at roof, and open just Often the roof door of door height could facilitate upper and lower roof, the most not only has individual staircase projection to affect building at roof overall Attractive in appearance, and too increase the construction cost of staircase；As set up outside room roof on forestair the most unsightly, and hold Subject to wind and rain Exposure to Sunlight to corrode, so the stair of the upper roof of great majority are that to be built in be main within doors.In order to keep the whole of building Body is attractive in appearance, and in minimizing, roof builds stair and the cost of staircase, and facilitates upper and lower roof, is badly in need of design a kind of new-type upper The technical scheme of roof.

The purpose of this utility model is the scheme for designing structure a kind of roof door of offer between a kind of Novel staircase, to solve Above-mentioned the deficiencies in the prior art, have simple in construction, construction cost is low, can build up and flush with parapet compared with the prior art Stealthy staircase, holding building overall appearance are smooth attractive in appearance, facilitate the advantages such as upper and lower roof.

Summary of the invention

The technical solution of the utility model is: propose for the door designing setted structure use of described roof staircase A kind of roof gate technique scheme, the design structure of described roof staircase is mainly by body of wall, stair, lamina tecti and door opening group Becoming, the lamina tecti of a composition staircase at least oblique capping is constituted, and the lower end of oblique capping connects on top floor or floor Parapet, other periphery and wall connecting, door opening is positioned at the lamina tecti of oblique capping.The lamina tecti of composition staircase, turns being provided with The stair of platform can be constituted lamina tecti by an inclined-plane and a plane, and skewback is predominantly on the top of stair step, surface plate It is predominantly on the top of stair turntable, it is possible to be directly made up of at least one sloped roof cover plate；Can to the stair not being provided with turntable Lamina tecti is constituted, it is possible to be directly made up of at least one sloped roof cover plate by an inclined-plane and a plane.Inside it is provided with door opening The angle α that lamina tecti inclined-plane forms with top floor face is: 90 ° of ＜ α ＜ 180 °, door opening is the most flat with this lamina tecti inclined-plane OK.Being positioned at the door opening on lamina tecti inclined-plane, be arranged over a back timber, both sides are provided with a side bar, are provided with door below, and jointly to Outside door opening, protruding composition has dash and reinforces the door collar tie beam of door opening acting by their periphery.The surface plate portion of composition staircase lamina tecti Point, can horizontal bedding, it is possible to suitably tilt bedding, it is positioned at ceiling at a head and is about one to the vertical dimension of stairway step The height of door.Described roof door is mainly made up of doorframe, door leaf, door-hinge, support bar, sealing strip, door lock, handle, its feature Being: doorframe is contained in door opening outer periphery, door-hinge is arranged between doorframe and the top of door leaf, and support bar one end connects door leaf, separately One end connects doorframe or door collar tie beam.Doorframe top is set as short straight hook and hangs on the door beam of projection with set, and doorframe inner edge periphery is outside Protruding composition dash surrounding edge.The upper end of doorframe and door leaf is respectively designed to corresponding short the most hook-shaped, hangs on a back timber with folded, door Translating into lower hook eaves under fan periphery, be just buckled in doorframe waterproof groove during closedown, groove inner bulge becomes dash surrounding edge and higher than recessed Projection outside groove, with rainwater leakage prevention.In order to light and steadily switch door leaf, need to switch with support bar power-assisted door leaf, install Support bar between door leaf and doorframe or body of wall is the flexible member with near-linear elastic curve, as with gas and liquid Support bar for working media.Door leaf is swing type switching motion, and upper rotation is for opening, and backspin, for closing, blocks at door when door leaf leaves to the greatest extent Above hole.
