Abstract

The utility model discloses an improved structure for fire-proof doors, wherein, side frame strips are fixedly arranged on the junction of the side edges of two door plates. An edge frame is fixedly arranged on the side margin of each door plate. A plurality of connecting frames are fixedly arranged on the proper position of the edge frame. A plurality of spacer regions are formed between the connecting frames through the butt joint between the two door plates. The positions of the side frame strips corresponding to each spacer region are respectively provided a spray hole injected with light liquid fireproof PU foaming. Accordingly, the utility model can have a fireproof performance, and can have better bending resistant and impact resistant performances at the time of bearing temperature change.

Description

The labeled door structure-improved

The utility model relates to a kind of labeled door structure-improved.

In today that Building technology is showing improvement or progress day by day, modern architecture all has obvious lifting in structural strength and construction aesthetic perception, yet in building safety was healed valued modern society, the fire line of building promoted the real necessity that has; Thereby common temperature detecting system, sprinkler system, emergency access and the generally labeled door setting of the better fire line of door body tool in the modern architecture.

And just Taiwan and the world respectively want country to regard to the standard of labeled door, its heat-resisting heat run temperature grade generally is divided into 30 fens, 1 hour, 2 hours, and the standard heating-up temperature is respectively 840 ℃, 925 ℃, 1010 ℃, and Taiwan is that regulation must be when Men Tiyi side heating 1 hour and temperature reach 925 ℃ at first kind labeled door, its body opposite side temperature must not be higher than 260 ℃, and the door body must not overshoot distortion curvature and produce the crack, produce the flame gap of circulating to prevent a body.

And known more novel Fireproof door structure is announced shown in No. 309987 as Fig. 5 Taiwan, mainly vertical in labeled door, horizontal housing 11 ', be provided with two-layer internal-rib frame 20 ' in the space that 12 ' and two door-plates 10 ' are enclosed, and wife's frame 20 ' is in last, establish the vertical rib bar 21 ' that a section is Jiong shape between horizontal housing 12 ' down, and wear the horizontal bar 22 ' that helps in vertical rib bar 21 ', and the horizontal bar 22 ' that helps stays on indulging on the housing 11 ' of both sides, another internal-rib frame 20 ' then is located at another door-plate 10 ', and keep a gap between two internal-rib framves 20 ', and establish a PLASTIC LAMINATED 30 ' in two internal-rib framves 20 ' folder, to constitute labeled door.

Though yet aforementioned structure can have better fire line by general door body, but because of door-plate 10 ' and PLASTIC LAMINATED 30 ' tool one clearance space, its intensity is not good, and door-plate 10 ' easily produces the torsional deformation situation when bearing high temperature, and door-plate 10 ' easily produces indent even produces the disappearance in crack when being subjected to external force collision.

And for example shown in Fig. 6,7 be Taiwan another announce Fireproof door structure No. 322115, be to be hollow state between two door-plates 40 ' of this labeled door wherein, and fill between door-plate 40 ' must ready mix concrete 50 ' and plastic rubber material 60 '.

Owing in two door-plates 40 ' the higher concrete of proportion 50 ' material is set when only aforementioned structure is implemented, make this body weight significantly to increase, and far surpass general labeled door weight, and cause child or physical chump to be difficult to promote to open the labeled door situation, do not meet fire prevention escape requirement.

Do not link because of two door-plates, 40 ' central authorities have skeleton again, make that door-plate 40 ' central authorities easily produced the dilatancy situation when door body was heated.

The purpose of the utility model be to provide a kind of can have fire line and can be when bearing high temperature the labeled door structure-improved of the preferable anti-tortuosity of tool and resistance to impact.

For reaching above-mentioned purpose, the utility model two door-plate side junction surfaces set firmly the side frame bar, and set firmly frame in the door-plate lateral margin, it is characterized in that: this side frame bar appropriate location sets firmly some binding frames, and it is fixed by the butt joint of two door-plates, each links the some spacer regions of formation between frame, is provided for injecting the spray-hole of the liquid fire prevention of light weight PU foaming again respectively in the position, the corresponding each septal area of side frame bar of door body.

By above structure, the utility model promptly has following characteristics:

1, some binding frames is set between two door-plates, makes door-plate can have better anti-tortuosity.

2, fire prevention PU foaming is set between two door-plates, makes the preferable fire line of Men Tike tool, and, can prevent to produce when door-plate is impacted indent or crack situation because of being solid between two door-plates.

3, the fire prevention PU foaming of light weight is set, the easily user demand of promotion when making a body weight can meet escape in two door-plates.

4, respectively link on the frame, downside engages by fire prevention PU foaming respectively and coats, and makes Men Tike have better entire combination intensity.

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 be the utility model partly make up cross-sectional schematic;

Fig. 2 is the structural representation of the utility model;

Fig. 3 is that the group of the utility model is established the action schematic diagram;

Fig. 4 is that the group of the utility model is established cross-sectional schematic;

Fig. 5 is known product structure schematic diagram;

Fig. 6 is known product structure schematic diagram;

Fig. 7 is known product structure schematic diagram.

See also Fig. 1,2, the utility model mainly sets firmly side frame bar 2 in 11 welding of the junction surface of two door-plates, 1 side, and set firmly some Jiong types in side frame bar 2 appropriate locations welding and link frames 3, respectively link 3 of frames when making two door-plates, 1 butt welding in spot fixed and form several spacer regions 4, and the dual side-edge of binding frame 3 can be affixed to promote the anti-tortuosity and the impact resistance of door-plate 1 by fire prevention and two door-plates, 1 inner face; In 4 positions, side frame bar 2 corresponding each septal areas of door body both sides spray-hole 5 is set respectively again.

See also Fig. 3,4, the spray-hole 5 of these 4 both sides, each septal area connects the injection tube head respectively, and the liquid state fire prevention PU foaming 6 of injecting light weight simultaneously with high pressure, make this fluidised form fire prevention PU foaming 6 can be full of in the spacer region 4 rapidly, and can in the short time, condense into solid (in about 2 minutes), and because spacer region 4 two sides are injected liquid fire prevention PU foaming 6 simultaneously, make this liquid state fire prevention PU foaming 6 can be riddled in the spacer region 4 before not condensing into solid as yet, and simultaneously can by fire prevention PU foaming 6 with link on the frame 3, following side engagement is to promote door body entire combination intensity; In the welding of door-plate 1 lateral margin frame 7 is set again, makes frame 7 can cover each spray-hole 5, and can promote a side edge intensity.

Claims

1, a kind of labeled door structure-improved, wherein two door-plate side junction surfaces set firmly the side frame bar, and set firmly frame in the door-plate lateral margin, it is characterized in that: this side frame bar sets firmly the binding frame, and it is fixed by the butt joint of two door-plates, each links and forms spacer region between frame, is provided for injecting the spray-hole of the liquid fire prevention of light weight PU foaming again respectively in the position, the corresponding each septal area of side frame bar of door body.
