Abstract
The utility model discloses a kind of plastic-steel door and window with connecting corner brace, it comprises plastic corner brace, rectangular bolt and truncated cone-shaped expanding block; There are 45 ° of inclined planes plastic corner brace one end, and there is the cavity matched with truncated cone-shaped expanding block the other end, and cavity wall evenly has multiple perps; The butt end end face of truncated cone-shaped expanding block is fixed with the nut matched with rectangular bolt, taper end is plugged in the cavity of plastic corner brace; Have the via hole of rectangular bolt in plastic corner brace and truncated cone-shaped expanding block, rectangular bolt is threaded on nut through via hole in plastic corner brace and truncated cone-shaped expanding block; The inclined plane of plastic corner brace is evenly distributed with multiple projection.Use plastic-steel door and window of the present utility model, the bonding strength at its group angle place is high, reduces the generation of corner crack phenomenon, improves application life, add its sealing performance, and then enhance its tightness and watertightness, heat preservation energy-saving.The utility model is processed simply, is easy to operation, and highly versatile, application life is strong.
Description
Technical field
The utility model relates to a kind of component of building plastic-steel door and window, especially relates to a kind of plastic-steel door and window corner cut intensity that 45 ° are spelled angle place and connects corner brace.
Background technology
The plastic-steel door and window used in the market, it adopts inner form of adding steel lining to carry out the raising of bulk strength, and bight adopts 45 ° to organize angle connection.At its bight connecting portion, process owing to adopting welding manner, it can only carry out the welding of casing plastic, its inner steel lining can not weld in junction, steel lining has the cavity of 5-10mm in the position of 45 ° of corner cuts, so its bight link position belongs to weak link, easily causes corner crack when running into high wind pressure, cause doors and windows sealing poor, application life is low.
Utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of plastic-steel door and window with connecting corner brace, is fixed in steel lining by this corner brace grafting, can strengthen plastic-steel door and window bight bonding strength, reduces the generation of corner crack phenomenon.
For achieving the above object, technical solution of the present utility model is: a kind of plastic-steel door and window is with connecting corner brace, and it comprises plastic corner brace, rectangular bolt and truncated cone-shaped expanding block; There are 45 ° of inclined planes plastic corner brace one end, and there is the cavity matched with truncated cone-shaped expanding block the other end, and cavity wall evenly has multiple perps; The butt end end face of truncated cone-shaped expanding block is fixed with the nut matched with rectangular bolt, taper end is plugged in the cavity of plastic corner brace; Have the via hole of rectangular bolt in plastic corner brace and truncated cone-shaped expanding block, rectangular bolt is threaded on nut through via hole in plastic corner brace and truncated cone-shaped expanding block; The inclined plane of plastic corner brace is evenly distributed with multiple projection.
Truncated cone-shaped expanding block described above is unit of plastic or metal derby.
During use, corner brace will be connected and insert plastic-steel door and window steel lining section bar inside, rotate rectangular bolt, plastic corner brace is driven to move to truncated cone-shaped expanding block butt end, make plastic corner brace tensioner in steel lining section bar, during two groups of angle section welding, the projection on the inclined plane of plastic corner brace of the present utility model is melted, and two inclined planes also bond together.The utility model is filled with the cavity in group angle place two section bar between steel lining, plays the effect strengthening supporting.Use plastic-steel door and window of the present utility model, the bonding strength at its group angle place is high, reduces the generation of corner crack phenomenon, improves application life, add its sealing performance, and then enhance its tightness and watertightness, heat preservation energy-saving; And outward appearance one, frame fan eurythmy.The utility model is processed simply, is easy to operation, and highly versatile, application life is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposition texture schematic diagram of the present utility model;
Fig. 3 is the decomposition texture schematic diagram that the utility model is arranged in plastics-steel shapes for door and window steel lining.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1, Figure 2 and Figure 3, the present embodiment comprises plastic corner brace 3, rectangular bolt 2 and truncated cone-shaped expanding block 5.Truncated cone-shaped expanding block 5 is unit of plastic, may also be metal derby.There are 45 ° of inclined planes 1 plastic corner brace 3 one end, and there is the cavity matched with truncated cone-shaped expanding block 5 the other end, cavity wall 4 evenly has multiple perps 6.The butt end end face of truncated cone-shaped expanding block 5 is fixed with the nut 8 matched with rectangular bolt 2, taper end is plugged in the cavity of plastic corner brace 3.Have the via hole of rectangular bolt 2 in plastic corner brace 3 and truncated cone-shaped expanding block 5, rectangular bolt 2 is threaded on nut 8 through the via hole in plastic corner brace and truncated cone-shaped expanding block.The inclined plane 1 of plastic corner brace is evenly distributed with multiple protruding 7.9 is steel lining, and 10 is plastics-steel shapes for door and window.
Above-described embodiment is only preferred and exemplary, and those skilled in the art can carry out the improvement of equivalent technologies according to the description of this patent, it is all in the protection domain of this patent.
