Description

A kind of sliding door and window
Technical field
The invention belongs to window technology field, and in particular to a kind of sliding door and window.
Background technology
The major defect of existing sliding door and window is poor waterproof properties.Seam crossing between door and window and wall is used at fluid sealant Reason, fluid sealant aging or seal incomplete caused by construction reason, cause the drop of sealing property with the increase of usage time Low, outdoor rain easily infiltrates into wall;Groove structure is formed between the housing slide rail of sash lower transverse frame, inside casing slide rail, baffle plate, Easy ponding, ponding easily penetrate into wall from the junction of lower transverse frame and munnion;The housing of window frame is connected with inside casing by heat insulating strip, with The increase of usage time, the sealing between heat insulating strip and interior housing is caused due to reasons such as the deformations or heat insulating strip aging of window frame Performance reduces, and ponding penetrates into wall from seam.
Discharged water poor performance to solve door and window, the problem of air-tightness is poor, Normal practice is two after sash splicing Daub is held, or it is undesirable using gasket seal, effect.First, daub cannot be guaranteed that splicing seams tightly seal, and easily production Rubber pollutes;Secondly as fluid sealant does not have adhesive strength, glue cracking is easily caused in transport/handling process, is not had close Seal effect;Third, gasket seal has certain water imbibition in itself, easily mouldy to rot, service life is shorter, from substantial solution Never seepage problem.Therefore, the present inventor makes further research to this, develops a kind of sliding door and window, thus this case produces.
The content of the invention
In order to overcome the shortcomings of described in background technology, the present invention provides a kind of sliding window, and the sliding door and window is able to ensure that spelling Seam tightly seals, and fundamentally solves seepage problem, improves the air-tightness of whole window.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of sliding door and window, including horizontally disposed upper cunning and downslide and two bandings being vertically arranged, upper cunning, downslide And two bandings form an erection of doors and windows framework.
Described upper cunning connects inner profile frame by two heat insulating strips and outer profile frame forms, and upper sliding bottom is provided with sliding modeling Material, upper sliding plastic play a part of enhancing heat preservation and insulation;Wool top is provided with the groove of inner profile frame, wool top is set Groove is provided at both ends with wool top plug, and wool top can prevent mosquito from entering, and thermal insulation simultaneously prevents rainwater to be splashed into;Outer profile frame side is consolidated Surely connect apron flashing, apron flashing can rainwater-proof stitched from door and window rail top or lower cap head seam flow into it is indoor.
Described downslide is made up of two heat insulating strip connection inner side frame of section bar and outside frame of section bar, the height of inner side frame of section bar Apparently higher than the height of outside frame of section bar, be advantageous to rapid draining, it is indoor to prevent that rainwater from penetrating into, inner side frame of section bar upper part and outer Side frame of section bar upper part is provided with glidepath, and two glidepaths are parallel to each other, by that will pacify on two glidepaths Dress door and window lower bottom part is installed on downslide upper surface.
Described banding is made up of two heat insulating strip connection inner side fan bandings and outside fan banding;Fan banding medial surface in outside Leather strap card interface is vertically arranged with, leather strap is decorated by leather strap card interface clamping banding, sets banding to decorate leather strap and plays decoration Effect, improve the aesthetics of the sliding door and window;Banding is fanned in inner side and the medial surface junction of outside fan banding forms an installation Groove, be provided between mounting groove upper and lower ends and upper cunning and downslide connecting portion hole for injecting glue banding closedtop is stifled and the low envelope of banding Stifled, banding closedtop, which is blocked up between upper cunning, is provided with sliding closure, is provided with closure of gliding between the low closure of banding and downslide, passes through The hole for injecting glue that banding closedtop is blocked up in closure low with banding carries out injecting glue, and glue seals in the presence of extruding to splicing seams, Ensure that splicing seams tightly seal;Banding plastic, banding modeling are installed in the stifled mounting groove between the low closure of banding of banding closedtop Material can enhance heat preservation and insulation;Bayonet socket is provided with banding plastic, being arranged with banding by bayonet socket seals leather strap, door and window Banding sealing leather strap is squeezed power bounce-back when fan is closed, and greatly improves air-tightness, watertightness.
Preferably, described banding closedtop blocks up lateral surface middle position and is provided with notch, the banding closedtop directly over notch Block surface and be provided with top hole for injecting glue, banding closedtop blocks up left and right sides and is arranged at intervals with the top step knot to bend inwards Structure, spaced top step structure are mutually agreed with mounting groove so that banding closedtop blocks up buckle and is installed on inside mounting groove, leads to Cross top hole for injecting glue and glue is injected into the stifled inside of banding closedtop, glue can block up outer surface in banding closedtop and set from the spilling of notch Upper sliding closure bumping post notch, because banding closedtop blocks up smaller, set notch make it that injecting glue is full, ensures to splicing seams Preferably realize sealing.
Preferably, the low closure left and right sides of described banding are arranged at intervals with the bottom hierarchic structure to bend inwards, left The bottom hierarchic structure of right two sides is mutually agreed with mounting groove, and an inside casing, inside casing and bottom are provided with the inside of the low closure of banding Hierarchic structure it is highly consistent, the low closure bottom surface of banding between inside casing and bottom hierarchic structure is provided with bottom hole for injecting glue. The low closure of banding is blocked up compared to banding closedtop, and its volume is larger, it is necessary to an inside casing is set inside it, just can guarantee that and pass through bottom It is fuller that portion's hole for injecting glue is injected into its internal glue, it is ensured that splicing seams tightly seal, and improve the air-tightness of whole door and window.
Preferably, described banding plastic is that section is S-shaped structure, and S-shaped structure upper and lower ends distinguish shape up and down Into the projection mutually snapped connection with mounting groove so that banding plastic is preferably installed on inside mounting groove, strengthen door and window every Hot heat-insulating property.
It is an advantage of the invention that:
(1)Mounting groove between inner side fan banding of the invention and outside fan banding is blocked using special injecting glue, and lap-joint sets Put multiple-sealed, sealing property greatly improves, and efficiently solves stitching portion seepage problem;
(2)Sliding sash corner of the present invention sets anti-sway, injecting glue integral seal, can effectively improve flatness, also can Ensure the tight sealing of splicing seams, greatly improve air-tightness, watertightness.
