Abstract
The utility model discloses a protective sealed door and the bound edge thereof including an integrated frame, of which the cross section is a combination of a C-shaped main body and a later handle. The steel plate employed in the utility model is formed through one-time bending, which reduces cost. Corners are circular and smooth, which is unlikely to hurt hands. Moreover, the appearance is beautiful, and the market competitive edge is sharpened.
Description
Technical field
The utility model is the improvement to steel bar concrete airtight blast door, sealed door door leaf bound edge, relates in particular to a kind ofly to economize with material, makes simple steel bar concrete airtight blast door, sealed door door leaf shell steel framework bound edge.
Background technology
Steel bar concrete airtight blast door, sealed door are to be used for the people's air defence basement; And the converting from wartime to peacetime production and vice versa that the underground space is taken into account people's air defense and needed uses partition door, adopts reinforced concrete structure usually, for satisfying corresponding protective capacities; Usually do thicklyer; Quality is heavier, and for example gate-width is that single fan closed guard gate weight of 2.0 meters reaches 2.5 tons, therefore the door leaf steel framework is required that enough intensity and stiffness need be arranged; Secondly, requiring must have the sealing edge of a knife on the door leaf steel framework.Prior art adopts the moulding of channel-section steel assembly welding usually; In-line edge of a knife vertical welding is connected to the channel-section steel side, yet door leaf steel framework height is generally about 2.2 meters the so solder side of length inevitable generation thermal deformation in welding process; Be prone to cause channel-section steel and the flexural deformation of the sealing edge of a knife; After welding is accomplished, must carry out mechanical checkout to it, increased the correction work amount.Because of present no corresponding special-shaped material, so can only select the bigger channel-section steel of specification, cause with material increase, recruitment increases.Above-mentioned deficiency still has is worth improved place.
Summary of the invention
Goal of the invention: the purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of making simple, with the protection door leaf bound edge of material province.
Technical scheme: in order to solve the problems of the technologies described above, described airtight blast door of the utility model and sealed door door leaf bound edge, it is made up of the integral type frame, and this integral type frame cross section is the combination of C shape main body and horizontal handle.
Said C shape main body and horizontal handle are the one cold roll formings.
Said integral type frame adopts the steel plate of 4mm.
The horizontal handle of said integral type frame is shorter, and length is 16mm.
The length of said C shape main body is 100mm, and width is 40mm.
The corner of said integral type frame is circular-arc.
The utility model, not only can be selected to be fit to the steel plate of thickness, thereby reduced to use the blocked up waste that causes according to the door leaf actual (real) thickness owing to adopt bending forming of steel plate with respect to prior art; Secondly, cold roll forming does not need to weld again, thereby has avoided the distortion that produces in the manufacturing process, does not need to carry out shaping again, and the 3rd, the somewhat little circular arc of the corner angle of cold roll forming, smooth nature, good hand touch is difficult for hindering hand, and good looking appearance has increased the market competitiveness.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: steel plate adopts a bending forming, has lowered cost, and corner is relatively slicker and more sly, is difficult for hindering hand, good looking appearance has increased the market competitiveness.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein:
1, integral type frame; 2, C shape main body; 3, horizontal handle; 4, corner
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, described airtight blast door of the utility model and sealed door door leaf bound edge, it is made up of integral type frame 1, and this integral type frame 1 cross section is the combination of C shape main body 2 and horizontal handle 3; Said C shape main body 2 is one cold roll formings with horizontal handle 3; Said integral type frame 1 adopts the steel plate of 4mm; The horizontal handle 3 of said integral type frame 1 is shorter, and length is 16mm; The length of said C shape main body 2 is 100mm, and width is 40mm; The corner 4 of said integral type frame 1 is circular-arc.The utility model steel plate adopts a bending forming, has lowered cost, and corner is relatively slicker and more sly, is difficult for hindering hand, and good looking appearance has increased the market competitiveness.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
