Thin combined installation door and window auxiliary frame

Abstract

The invention discloses a thin combined installation door and window auxiliary frame which is made of metal or plastic profiles and has a bridge-breaking heat insulation type and an ordinary type, wherein each type has a push-pull mode and a sliding mode. The auxiliary frame is in a shape of double Es, the thickness of the auxiliary frame is larger than 4mm and smaller than 15mm, wall fixing screws and angle steel fixing screw grooves are arranged on the surface of the auxiliary frame, and an angle steel groove and angle steel are arranged on the back surface of the auxiliary frame. The auxiliary frame is provided with a standard seat frame for supporting the installation of the auxiliary frame, wherein the seat frame is made of aluminum alloy or metal profiles and has an adjustable mode and a fixed mode. Clamping rods, clamping hooks, horizontal correction devices, vertical correction devices, sill concentric correction devices and rulers are arranged on the seat frame. In installation, the auxiliary frame is fixed on the seat frame through the screws, the seat frame is installed in a door and window hole to be clamped tightly, correction is performed through a correction device, a wall horizontal inked line and a wall vertical inked line, hard plastic gaskets are wedged the back surface of the auxiliary frame tightly, the auxiliary frame is fixed on the wall through two lines of screws, the seat frame is dismantled, cement mortar is filled in slits between the frame and the wall, and a firm standard door and window auxiliary frame is formed after the cement mortar is coagulated.

Description

Technical field: [0001] The invention relates to the field of door and window sub-frames, in particular to a thin-type combined installation door and window sub-frame. Background technique: [0002] Existing aluminum alloy and plastic doors and windows are hand-made in the workshop to form door and window frames and fan frames. This structure and production method is that the frame is very weak and must be connected to the wall before it can be stably fixed. The first-stage installation process: package the door and window frame, leave a 10mm gap between the inner and outer frames during packaging, paste the double-sided adhesive tape on the screw hole on the back, and transport it to the door and window hole; , Make the exterior wall waterproof layer, water the floor, pop up the horizontal and vertical ink lines at fixed points, first temporarily fix the door and window frame on the door and window holes, and use temporary wood according to the position of the door and wind...

Problems solved by technology

[0003] The above installation methods have the following disadvantages: the originally weak frame is deformed after several times of handling or the wrapping paper is partially damaged. Most of the existing high-rise walls are made of soft lightweight bricks, which are fixed with steel nails due to bumps and fillings. The expansion force of the mortar will loosen and cause the frame to deform and move. The reason is that when the smooth steel nails with the same diameter at the head and tail are pressed in by the hammer, they will squeeze and loosen the light bricks to expand and loosen the steel nails. , Ding Ding, and steel nails nailed to the head cannot meet the frame adjustment requirements with a unit of 1mm, and the deviation is inevitable. In addition, the anchor iron sheet and long wooden wedge will interfere with the filling of the mortar, and the unsaturated cement mortar will reduce the strength of the frame. Compatible with waterproof performance, saturation will bulge and squeeze the frame deformation to increase the error; in order to use the laser ink line meter to refer to the indoor ground horizontal ink line to correct the frame by using the external wall ink line, there will be horizontal errors in the window level between rows plus the horizontal error of the masonry on the external wall tiles rate, causing the push-pull drainage holes to be blocked, and the outer side-opening fan frame to be unable to be installed. To save labor, the error of correcting the frame with a level ruler is larger; the outer wall materials and workers must enter and exit from the frame, which is inevitable. It will damage the frame and wrapping paper, and some of them must be replaced if they are damaged by falling objects from the upper layer. When the film is applied to the labor-saving frame packaging, there is no edge left on the inner and outer back, which will cause a temporary interlayer. Corrosion will cause the waterproof glue to crack and be cleaned Alkaline water on the wall will leak through the joints of the wrapping paper or directly invade the surface of the corroded frame from the damaged part. The damage to the sand surface, flat surface and polishing material is more serious, and sometimes the whole part needs to be replaced. If the construction period exceeds six months, it will also appear. The wrapping paper is fixed on the frame and it is difficult to tear and clean; the door and window frame and leaf are an active combination of a square and a square, or a square and several squares, and the concentric flatness of positive angles is very high. , and the above reasons,
