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] The existing aluminum alloy and plastic doors and windows are hand-made in the workshop and combined into 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 to be stable and fixed. The first stage of the installation process: when packaging the door and window frames, there must be a 10mm gap between the inner and outer frame surfaces, and the screw holes on the back are pasted with double-sided tape and transported to the door and window holes; waiting for the mason to make the external wall batch file , After making the external wall waterproof layer, water-polished floor, fixed-point ejection of horizontal and vertical ink lines, first temporarily fix the door and window frames on the door and...

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, as well as the constraints of high-altitude operations, multiple types of construction on construction sites, safety, and deadlines, there are still large errors in the careful installation of the frame, and the large error will increase the difficulty of installing tempered fixed glass and reduce the fall-off prevention of doors and windows. , waterproof, leak-proof, energy-saving, sliding opening and closing performance, if the error is too large, it is necessary to change the size of the fixed glass or fan frame to install it

Although the steel square tube sub-frame solves the original shortcomings, it has a new disadvantage: it must be made of galvanized square tubes with a wall thickness of more than 2mm and a thickness of more than 25mm so that it will not be weak and heavy, and it will be troublesome to transport and install; Arc welding will cause deflection and warping deformation, so it is very labor-intensive to make a sub-frame with positive angles and flatness, and the single area exceeds 3m 2 It is necessary to add welding temporary support before removing it, otherwise it will sag and deform, it is difficult to install, and the cost of anti-rust paint must be high. Moreover, the screw holes at the bottom will cause a small amount of water leakage, and the sub-frame is on the surface of the door and window. Long-term slight leakage of water will cause the square pipe to rust and swell off the outer wall tiles and waterproof glue joints. The closed square pipe cavity has a speaker effect. There is a lot of echo when the sliding door frame slides. The biggest disadvantage is that the thickness of the sub-frame needs to be wrapped with cement mortar on both sides to the inner plane, which will increase the difficulty and workload of the mason to make the inner and outer window sills. When there is a gap of 20-25mm, the inner and outer window sills should be filled with 45-50mm of mortar, especially the suspension mortar on the top of the sub-frame and the lintel, which must be divided into 2-3 times with an interval of 24 hours each time to make the door and window sill. If the edge deviation of the door and window opening is just above the sub-frame, it is more difficult to make a suspended window sill of more than 50mm, which will increase the cost of the sub-frame, and the danger of cracking and falling if the suspension is too thick. The main disadvantage is that the sub-frame will conduct heat and is not suitable for use in insulating doors and windows. The above shortcomings make it difficult to popularize and apply the sub-frame technique of steel square tubes
