Abstract
The utility model relates to closed guard gate's technical field, particularly relates to a kind of sealed door sash structure, comprises doorframe and embedded pressing bar, and the cross sectional shape of doorframe is U-shaped, and embedded pressing bar is arranged on a side of doorframe, embedded pressing bar and doorframe integrated setting.Goal of the invention of the present utility model is to provide a kind of sealed door sash structure, while the technical scheme adopting the utility model to provide maintains former sash structure rigidity and intensity, by needing the embedded pressing bar of heat treatment to change cold working into, improve the steadiness between embedded pressing bar and doorframe.
Description
Technical field
The utility model relates to closed guard gate's technical field, particularly relates to a kind of sealed door sash structure.
Background technology
People's air defense is also known as civil defence, and be that government mobilizes and organizes the masses, take anti-air strike, measure of fighting calamities and providing relief, implement rescue action, the activity of strick precaution and disaster mitigation harm, the door of civil defence preventive works access is closed guard gate.
Wherein steel concrete sealed door is the one of closed guard gate, and existing steel concrete sealed door is spliced into the steel framework of interior sky by shaped steel, in frame, cloth muscle and disturbing concrete form.Steel concrete sealed door, also needs to arrange rubber strip on doorjamb to ensure its obturation effect when making.As shown in Figure 2, existing rubber strip technique for fixing often adopts and weld embedded pressing bar 20 on steel framework 10, compresses rubber strip play airtight effect by embedded pressing bar 20.
Under the carefully studying and verify of inventor, find that existing band has following defect in use:
Doorjamb 10 structure that shaped steel welds embedded pressing bar 20 belongs to hot-working, need the weld seam of welding very long, require high to solder technology, very easily produce various bending and torsional deformation, and produce larger internal stress, have a strong impact on dimensional errors and the planeness of door leaf, and then affect seal, manufacturing scrap rate is high.
Utility model content
Goal of the invention of the present utility model is to provide a kind of sealed door sash structure, while the technical scheme adopting the utility model to provide maintains former sash structure rigidity and intensity, by needing the embedded pressing bar of heat treatment to change cold working into, improve the steadiness between embedded pressing bar and doorframe.
In order to achieve the above object, the utility model provides a kind of sealed door sash structure, comprises doorframe and embedded pressing bar, and the cross sectional shape of doorframe is U-shaped, and embedded pressing bar is arranged on a side of doorframe, embedded pressing bar and doorframe integrated setting.
Because the utility model is that steel plate bending is become certain shape, embedded pressing bar and doorframe integralization are arranged, the doorframe of this structure is adopted to maintain the same rigidity of former sash structure and intensity, also can meet closely cooperating between embedded pressing bar and doorframe simultaneously, and then ensure that the airtight effect of the rubber strip compressed by embedded pressing bar, and by needing the embedded pressing bar of heat treatment to change cold working into, improve the steadiness between embedded pressing bar and doorframe.
As further improvement of the utility model, embedded pressing bar is arranged at the end of described doorframe one side, or embedded pressing bar is arranged at the centre position of doorframe one side.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.Apparently, the accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model embodiment doorframe schematic diagram;
Fig. 2 is the utility model prior art doorframe sectional view;
Fig. 3 is the utility model embodiment doorframe sectional view;
Fig. 4 is the sectional view of the another kind of position of the utility model embodiment doorframe.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
embodiment 1
As shown in Figure 3, present embodiment discloses a kind of sealed door sash structure, comprise doorframe 10 and embedded pressing bar 20, the cross sectional shape of doorframe 10 is U-shaped, and embedded pressing bar 20 is arranged on a side 11 of doorframe 10, embedded pressing bar 20 and doorframe 10 integrated setting.
Because the utility model is that steel plate bending is become certain shape, embedded pressing bar and doorframe integralization are arranged, the doorframe of this structure is adopted to maintain the same rigidity of former sash structure and intensity, also can meet closely cooperating between embedded pressing bar and doorframe simultaneously, and then ensure that the airtight effect of the rubber strip compressed by embedded pressing bar, and by needing the embedded pressing bar of heat treatment to change cold working into, improve the steadiness between embedded pressing bar and doorframe.
As shown in Figure 3-4, wherein embedded pressing bar 20 can be arranged at the end of doorframe 10 1 side 11, or is arranged at the centre position of doorframe 10 1 side 11.
Above-described embodiment, does not form the restriction to this technical scheme protection domain.The amendment done within any spirit at above-mentioned embodiment and principle, equivalently to replace and improvement etc., within the protection domain that all should be included in this technical scheme.
