Description

Building energy-saving outward casement window with safety guardrail and mosquito-proof function

Technical Field

The invention relates to a building energy-saving heat-insulating outward casement window, in particular to a structure with a detachable invisible mosquito-proof screen window at an opening leaf part, a detachable anti-falling guardrail and a guardrail rod capable of being installed on a lower fixed window.

Background

The energy-conserving outer flat-open window of building that current engineering field used except only door and window open, close, energy-conserving function, no longer has other functions, if: the mosquito-proof function, open fan position and do not have child anti-falling function, the fixed window does not have the guardrail function of seting up defences.

In order to meet the completion acceptance standard specified in residential design Specifications (GB 50096-2011), the existing energy-saving casement window for buildings can be used for completion acceptance only by adding a zinc steel protective railing; after the zinc steel protective railing is additionally arranged, the indoor space is occupied; the hollow glass of the casement window is generally installed outdoors, so that the hidden danger of safety of constructors and the risk of falling of the glass from a building exists; the conversion frame can realize the interior installation of the hollow glass, but the cost of the aluminum alloy door and window is obviously increased.

Due to the problems and the defects, most developers pay houses to owners through completion and acceptance, and because doors and windows installed by the developers do not have the functions, the owners start to dismantle old windows and replace new windows after receiving house-handing keys, and dismantle zinc steel protective railings which are not attractive and occupy indoor space. The system door and window with the anti-mosquito screen sash or the anti-falling guardrail for children with individual requirements is required to be replaced besides the function of ventilation of the opening sash. And because the 'system door and window' requires that the aluminum profile has a wider series of scales (the width of the cross section) in order to realize anti-mosquito screen sash and child falling-prevention guardrail, the specification of the common system window is at least the requirement of 90 mm-145 mm series or larger scale, and the functions can be realized. Therefore, the cost of the system door and window is generally higher, generally between 800 and 1800 yuan/square meter, and the general family, especially the salary family is hard to bear.

The technical problem to be solved by the invention is mainly that aiming at the field of building engineering, the energy-saving side-hung door and window (a house built by developers or investors) for building in the field of existing real estate buildings is generally adopted between 50-80 series, and aluminum door and window profiles between 50-80 series only realize the opening and closing functions of an opening sash due to the limitation of section width, do not have the mosquito-proof function, do not have the falling-down prevention function for children at the opening sash part, do not have the protection railing function at a fixed window part, and can be checked and accepted as the completion only by additionally installing a zinc steel protection railing; the hollow glass generally adopts an outdoor installation process, so that potential safety hazards such as personnel safety risks and glass falling risks exist; when the 'conversion frame aluminum section' is adopted, the interior of the hollow glass can be realized, but the disadvantages of cost increase of the aluminum alloy door and window and the like are obviously overcome.

The indoor and outdoor surfaces of the frame material of the heat-insulation outward casement window are the same mold, and the indoor and outdoor surfaces of the stile material are the same mold, so that the stile material is universal internally and externally, and by adopting the design, the main section aluminum material mold can be reduced, the stock variety can be reduced, and the utilization rate of the aluminum material can be improved;

the notch width design of frame material, well club material, fan material is hinge notch (K groove or C groove) for uniform size, and the fixed window of being convenient for is general with the glass line ball of opening the fan, has reduced glass line ball aluminium alloy mould, has reduced the stock of glass line ball variety, has improved the utilization ratio of glass line ball aluminum product.

The design can also realize the universality of main section aluminum materials of the inward opening window and the outward opening window, namely the inward opening window and the outward opening window can be opened in an inward mode. The fixed glass can be embedded in the hollow glass without adding a conversion frame, so that the aluminum material is saved.

The sliding mechanism (sliding rail, vertical frame, etc.) of the invisible screen window can be the same section bar, plastic sliding grooves are embedded in the section bar, the two ends of the handle are provided with upper and lower plastic handle end sockets with opposite directions, the end sockets are provided with blocking blocks to limit the invisible screen from entering the screen box after contracting to proper positions, the plastic end sockets are assembled at the two ends of the aluminum product of the handle to form the handle of the invisible screen window, the plastic end sockets are provided with sliding blocks and small holes, and the small holes are used for fixing the screen. The sliding blocks are used for moving in the slide ways of the upper and lower tracks to stretch and contract the screen window, and the upper and lower handle end socket sliding blocks enter the upper and lower slide way grooves and the left or right hidden yarns are provided with locking strips, so that the screen can be prevented from wrinkling, the screen can be prevented from being blown away by wind, the aim of preventing mosquitoes is fulfilled, and the effects of sealing and preventing the handle from rebounding are also achieved.

Stealthy screen window is under shrink quiescent condition, and the screen window draws the hand power and is sheltered from by interior frame gib block, and is unusable, and the yarn section of thick bamboo box is blocked to first handle this moment, prevents that the screen window handle from further retracting. When the hidden yarn pulling device is used, the first handle is a traction handle, hidden yarns are slightly pulled out and are pulled away from the exposed inner frame clamping strip, and then the sunken second handle is a normal handle.

The connection of the screen mesh of the hidden screen, the screen cylinder and the screen sash handle is embedded, the problem that the hidden screen mesh in the current market only adopts a nylon mesh and is bonded on the screen cylinder by using a double-sided adhesive tape is solved, the hidden screen window can be made of a stainless steel screen mesh, and the purpose of preventing rat bites is achieved.

The embodiments of the present invention are described only for the preferred embodiments of the present invention, and not for the limitation of the concept and scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the design concept of the present invention shall fall into the protection scope of the present invention, and the technical content of the present invention which is claimed is fully set forth in the claims.
