Description

Technical Field

[0001] The utility model relates to the technical field of old door and window reconstruction, and specifically refers to an old door and window frame material reconstruction structure. Background Art

[0002] The doors and windows of second-hand houses and old buildings that are more than ten or twenty years old generally use aluminum alloy, steel, plastic steel, or wooden frame materials, single or double-layer glass, which can meet the most basic requirements of wind load resistance, water tightness, air tightness, and sound insulation, but the thermal performance is generally poor (ordinary plastic steel windows are slightly better), because single aluminum or steel frame materials are good conductors of heat, and become a bridge for conducting indoor and outdoor temperature differences; single-layer or ordinary double-layer insulating glass also has poor thermal insulation performance. Old doors and windows lead to high air conditioning energy consumption, and it is difficult to avoid fogging and condensation on doors and windows due to the temperature difference between indoor and outdoor.

[0003] In the face of many drawbacks of old doors and windows, many renovation methods have emerged. The method commonly used in the market is to dismantle the original old doors and windows and replace them with ordinary insulated aluminum alloy doors and windows or higher-end system doors and windows. This renovation method undoubtedly has obvious performance improvements compared to the original old doors and windows, but there are also problems such as high price and complicated operation.

[0004] There is also a renovation plan that uses the original doors and windows and adds a new plastic door and window on the indoor side; however, under this renovation method, problems such as the new frame and the old frame are not firmly connected and the installation is cumbersome.

[0005] Therefore, the transformation structure of old door and window frames has become an urgent problem to be solved. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a reconstruction structure for old door and window frame materials, which can realize the close connection between new and old door and window frame materials when the old doors and windows are reconstructed.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a reconstruction structure of old door and window frame materials, comprising a new frame and an old frame, wherein the new frame and the old frame are connected by a rubber strip;

[0008] The new frame includes a lower frame and an upper frame, both of which are rectangular and divided into upper and lower parts by a partition frame;

[0009] The upper frame and the lower frame both include a transverse frame and a longitudinal frame, and a cover plate is provided at the joint of the transverse frame and the longitudinal frame.

[0010] Furthermore, the rubber strips are arranged at intervals, and glue injection holes are left between adjacent rubber strips; structural glue is injected into the inner side of the rubber strips through the glue injection holes, and the structural glue bonds the new frame and the old frame together.

[0011] Furthermore, the bottom transverse frame of the lower frame includes a first frame body and a first slide rail and a second slide rail. The first slide rail and the second slide rail are both arranged on the top of the first frame body and are arranged in parallel.

[0012] Furthermore, the partition frame includes a second frame body, an upper slide rail and a lower slide rail. The upper slide rail and the lower slide rail have the same structure and are symmetrically arranged on the upper and lower sides of the second frame body.

[0013] The advantages of the utility model compared with the prior art are: the utility model connects the new window frame and the old window frame through the combination of adhesive strips and structural adhesives, making the connection between the two more firm, while increasing the horizontal and vertical load capacity of the window frame; the cavity structure and the thermal insulation effect of the double-sided adhesive strips + structural adhesives make the thermal insulation performance of the new and old door and window frame materials after the composite is greatly improved compared with the old doors and windows before the renovation.

[0025] The following is a further detailed description of the old door and window frame material reconstruction structure of the utility model in conjunction with the accompanying drawings.

[0026] Combined with Figure 1-7 , the utility model is introduced in detail.

[0027] A reconstruction structure for old door and window frames, comprising a new frame 1 and an old frame 2, which are connected by a rubber strip 3 so as to be combined into a whole; the new frame 1 comprises a lower frame 4 and an upper frame 5, both of which are rectangular and are divided into upper and lower parts by a partition frame 6; the upper frame 5 and the lower frame 4 both comprise a transverse frame 7 and a longitudinal frame 8, and a cover plate 9 is provided at the joint of the transverse frame 7 and the longitudinal frame 8.

[0028] Preferably, the rubber strips 3 are arranged at intervals, and glue injection holes 10 are left between adjacent rubber strips 3; structural glue 11 is injected into the inner side of the rubber strips 3 through the glue injection holes 10, and the structural glue 11 bonds the new frame 1 and the old frame 2 together. By injecting the structural glue 11, the connection between the new frame 1 and the old frame 2 is made more firmly.

[0029] In one embodiment of the present application, the bottom horizontal frame 7 of the lower frame 4 includes a first frame body 12 and a first slide rail 13 and a second slide rail 14. The first slide rail 13 and the second slide rail 14 are both arranged on the top of the first frame body 12 and the two are arranged in parallel. The lower frame 4 is connected and fixed to the wall through the first frame body 12, and the first slide rail 13 and the second slide rail 14 are used for the window sash to slide along them to open and close.

[0030] Preferably, the structure of the top transverse frame 7 of the upper frame 5 is the same as the structure of the bottom transverse frame 7 of the lower frame 4 and the two are symmetrically arranged.

[0031] In one embodiment of the present application, the partition frame 6 includes a second frame body 15 , an upper slide rail 16 and a lower slide rail 17 . The upper slide rail 16 and the lower slide rail 17 have the same structure and are symmetrically arranged on the upper and lower sides of the second frame body 15 .

[0032] Preferably, the structure of the longitudinal frame 8 is the same as that of the transverse frame 7; the same structure facilitates unified production and manufacturing, while the structural performance is guaranteed.

[0033] The specific implementation process of the utility model of a structure for transforming old door and window frames is as follows:

[0034] The new and old door and window frame materials are bonded into a whole through thickened strong EVA black foam double-sided adhesive strip 3 + structural adhesive 11, and jointly bear vertical and horizontal loads. The new frame 1 and the old frame 2 are combined into a whole, which enhances the lateral rigidity of the original door and window, and the ability to resist wind load will not only not be weakened, but will be greatly enhanced.

[0035] The adhesive strip 3 for bonding the new frame 1 and the old frame 2 adopts a strong EVA black foam double-sided adhesive strip 3, which has good thermal insulation performance due to the internal sponge bubble organization; according to the structural flatness of the surface of the old frame 2, the double-sided adhesive strip 3 with a thickness of 5, 8, and 10 mm is used to level the bonding surface of the frame material, and the double-sided adhesive strip 3 has the effect of temporarily (and permanently) fixing the new and old frame 2 materials; the width of the adhesive strip 3 is determined according to the exposed size of the old frame 2, the length of the adhesive strip 3 is not more than 50 cm, and an 8 mm wide gap is reserved at the splicing of the adhesive strip 3. After the temporary fixation and adjustment of the new and old frame 2 materials are completed, black structural glue 11 is injected into the reserved splicing gap of the adhesive strip 3. The double-sided adhesive strip 3 and the structural glue 11 work together to reliably bond the new frame 1 and the old frame 2 into a whole; because the linear double-sided adhesive strip 3 and the dot-shaped structural glue 11 are both poor conductors of heat, while bonding the new frame 1 and the old frame 2, they play a role of a broken bridge to isolate heat conduction.

[0036] The new frame 1 added on the indoor side is made of PVC-U plastic material with low thermal conductivity. In addition, the cavity structure of the frame 5 material and the thermal insulation effect of the double-sided tape 3 + structural adhesive 11 make the thermal insulation performance of the new and old door and window frame materials better.

[0037] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
